(Reporter Yuan Lu) In the future, I will not be afraid to go to the hospital to see a doctor or forget to bring my social security card when I buy medicine in a pharmacy. Just bring a mobile phone. At the first "Digital China" construction summit in Fujian on the 22nd, Ministry of Human Resources and Social Security announced that the first national unified electronic social security card was officially issued, which will be promoted nationwide. The electronic social security card is uniformly issued and managed by the national social security card platform, and has a one-to-one correspondence and unique mapping with the entity social security card.

　　So, how can we "put" the social security card into the mobile phone? It is understood that citizens only need to search for "city name+social security card" on Alipay’s homepage and pass the "brush face" certification to ensure their operation. Then, if you go to the pharmacy to buy medicine, you just need to show the QR code of the electronic social security card and scan the code to pay as usual, and the medicine fee will be deducted directly from your medical insurance balance, just like showing the physical social security card. If you are in a hospital, the public pays attention to the hospital’s Alipay life number. After the visit, you will receive the information to be paid pushed by the hospital life number in Alipay. Click to enter and select "medical insurance payment", and you can settle it with one click through the electronic social security card.

　　Is the electronic social security card safe? In this regard, the Ministry of Human Resources and Social Security said: "Security can be assured." The electronic social security card is based on ensuring the accuracy and security of the cardholder’s information. When users receive and use the card, they need real-time verification and confirmation from the third-party platform and the national social security card platform, and combined with internet security technologies such as electronic authentication and face-brushing authentication, to ensure that it is a "real person, real name and real card". At the same time, hospitals, pharmacies and other related information directly interact with the medical insurance system, and the data does not go through a third-party platform to ensure the safety of user information.

　　According to reports, at present, citizens of 14 cities including Hangzhou, Shenzhen, Wuhan, Xi ‘an, Chengdu, Xiamen, Hefei, Zhengzhou, Xiangtan, Zhenjiang, Tongchuan, Jiaxing, Yiwu and Kaifeng have been able to complete this operation. The data shows that as of the first quarter of 2018, the number of social security card holders nationwide reached 1.12 billion, with a penetration rate of 80.6%, covering all regions.

　　BEIJING, Beijing, March 12 (Reporter Guo Chaokai) On March 12, Ms. Zhang and Mr. Wang walked into the Marriage Registration Service Center of Xicheng District Civil Affairs Bureau in Beijing hand in hand, and went through the marriage registration formalities without barriers. It is reported that this is the first time that the Marriage Registration Service Center of Xicheng District Civil Affairs Bureau of Beijing has provided the visually impaired with a braille version and a large-character barrier-free format marriage registration standard document, and it is also the first time in China to provide the visually impaired with a barrier-free format marriage registration notice and wedding vows.

　　Ms. Zhang has a visual disability level 1, and Mr. Wang has a visual disability level 2. They can’t see or read ordinary characters clearly, so they can only touch Braille or read large characters. The Marriage Registration Service Center of Xicheng District Civil Affairs Bureau in Beijing took the initiative to set up a green channel for the two new couples after learning about their eyesight, and provided a braille version, a large-character version of the marriage registration notice and a wedding oath.

　　According to personal eyesight, Ms. Zhang and Mr. Wang respectively read the Braille version, the large-character version of the marriage registration notice and the wedding vows, and truly felt the sacredness and solemnity of marriage, and their joy and happiness were beyond words.

　　It is an important measure to implement the law of barrier-free environment construction to set up a green channel for marriage registration of visually impaired people and provide barrier-free format marriage registration standard documents to continuously improve the level of social public services. This measure is of great significance to effectively promote the construction of barrier-free environment and further protect the legitimate rights and interests of visually impaired people.

　　The law on barrier-free environment construction shall come into force on September 1, 2023. As the first special law on barrier-free environment construction in China, the law clearly stipulates that the national basic public services use the national general Braille.

　　In order to ensure that the notice of marriage registration in barrier-free format and the wedding vows are standardized and authoritative, the Marriage Registration Service Center of Xicheng District Civil Affairs Bureau of Beijing specially invited China Braille Publishing House to make the notice of marriage registration and the wedding vows in Braille and big characters. As the only comprehensive public welfare publishing organization in China that provides various cultural products and services for more than 17 million visually impaired people, China Braille Publishing House fully demonstrates the effectiveness of the national public welfare publishing and humanitarian communication base, actively undertakes the social responsibility of barrier-free environment construction, and has made positive contributions to further safeguarding and safeguarding the language and cultural rights of visually impaired people.

　　"Tao" is the core of Taoist school represented by Laozi and Zhuangzi. Taoism believes that "Tao" is the origin of the universe and the law governing all movements in the universe. Taoism advocates nature, peace and inaction, and supporting one’s life. Taoist thoughts such as "essence, qi and spirit" are closely related to traditional Chinese medicine and health preservation, such as diet and daily life, body and mind, etc. Here, we will analyze them from ten aspects: clothing, food, housing, transportation, fatigue, leisure, happiness, anger, fame and benefit.

　　1. The clothes are not too warm.Taoism pays attention to simple, decent and comfortable clothes, and chooses the most suitable clothes according to different seasons, different climates and different cultivation realms. If the human body’s meridians and qi and blood are smooth, there will be no feeling of cold. "Clothes are not too warm" means that we can’t rely too much on more clothes to keep warm, but we should improve our own disease resistance and vitality. For the problems of "covering" and "freezing", Taoism chooses "freezing" more. This is the truth that "wearing seven minutes of warmth will make God feel at ease".

　　2. Not enough to eat.Taoist practice is by no means "full of food and nothing to do", but to let go of the noise and noise of the world and seek a quiet and empty spiritual realm. "Not having enough to eat" means that it is not appropriate to eat and drink, and you should always keep your body hungry. Eating more is not conducive to health. As the saying goes, "There are always three points of hunger, and all diseases do not attack each other."

　　"Pigu" is a well-known Taoist health preserving method, which means that people will not eat fruits, vegetables, rice flour and fireworks cooked food for a period of time or even for a long time. It is right to recommend eating less, but professional guidance is needed for "crossing the valley", and ordinary people should not do it casually and blindly.

　　3. You can’t live in luxury.The living environment should be simple and grounded. The "Nine Observances" in Taoist health preservation is to ask people to keep the wind of luxury, to rise and fall with the Tao, and to live forever. Nine Shouts are: Shouhe-Harmony of Yin and Yang; Trustworthiness-the spirit of internal defense; Keeping qi-keeping blood gas inside; Abide by benevolence-follow the path of benevolence and righteousness; Keep simple-frugal to keep healthy and not greedy; Shouyi-don’t save your life for exogenous factors; Keep clear-clear and conform to nature; Keeping the surplus-contentment is always happy; Being weak-being happy with it and flattening its shape. Among them, keeping simplicity, keeping simplicity and keeping purity means advocating simplicity, incorruptibility, returning to nature.

　　4. you can’t be rich.Taoism does not exclude wealth, and "not being rich" means not chasing money excessively or being trapped by money. The line points out the line, behavior, behavior and action, which means that you can’t rely on luxury boats and cars for travel, you can’t spend a lot of money on behavior, you can’t value money over morality, and you can’t use money to clear the way. Taoism believes that "wealth can destroy qi", and excessive pursuit of money will affect cultivation and even cause "dispersion of essence".

　　5. You can’t work too hard.Taoist health care attaches great importance to physical cultivation and physical labor, but it also emphasizes that "moderate work does not hurt the body" and "five strains and seven injuries" is the taboo of Taoist health care. "Five strains" refers to blood injury caused by long-term vision, gas injury caused by long-term lying, meat injury caused by long-term sitting, bone injury caused by long-term standing, and tendon injury caused by long-term walking; The "seven injuries" refer to spleen injury caused by fullness, liver injury caused by anger, kidney injury caused by heavy lifting and sedentary wetland, lung injury caused by cold drinking, mental injury caused by physical exertion, physical injury caused by wind and rain, and mental injury caused by fear. Therefore, people who are good at keeping in good health should try their best to avoid damage to the five internal organs, qi and blood, meridians and bones due to excessive fatigue or excessive emotions.

According to Cailian News, the domestic big model competition continues. The science and technology innovation board Journal reporter learned exclusively from people familiar with the matter that MiniMax, a start-up project of general large model, is carrying out a new round of large-scale financing.Ali is the core lead investor.

Not long ago, the dark side of another big model startup, Moon, also reported the completion of financing of $1 billion, and Ali also appeared among investors.

The science and technology innovation board Journal reporter also learned exclusively that,In this round of large-scale financing on the dark side of the moon, most of the funds came from Ali.This also made Ali a major shareholder outside the dark side team of the month after this round of financing. What is more noteworthy is that,Part of Ali’s investment belongs to calculation payment.

It can be seen that Ali’s investment strategy for domestic large models is becoming more radical after the beginning of the year, and both the frequency and the amount of money are obviously rising. Prior to this, Ali had invested in Baichuan Intelligence, Zhipu AI and 10,000 things. At this point, Ali has completed investment coverage for the first few large domestic models.

Ali’s investment in domestic big models, in addition to holding shares and other considerations, is a more critical strategic point, or laying a first-Mover advantage for Alibaba Cloud’s competition in the AGI era. The strength competition of domestic large-scale entrepreneurial projects is becoming more and more fierce, and the competition and layout of internet giants in this field has also begun to get out of the differentiation situation.

Domestic big models burn money continuously.

The above-mentioned insiders said that the latest round of financing of MiniMax is still in progress, and the final amount has not yet been fully determined."But it will also be a big financing like the dark side of the moon."

The science and technology innovation board Journal reporter learned that most of the two large-scale financing of domestic large-scale models recently came from Ali’s contribution. As for the capital contribution logic of Internet giants including Ali, some investors have analyzed that in addition to holding these domestic large-scale model projects, it is also related to the future development considerations of cloud services of the big manufacturers themselves.

"The more the big model is trained to the back, the greater the capital investment is needed. Different from Internet applications, applications based on big models have to pay reasoning expenses in the use process, so they naturally rely on cloud vendors. Just like the overseas big model war situation, OpenAI binds Microsoft, while Anthropic binds AWS and Google. Internet and cloud service giants are facing this prospect, and their willingness to save money is also strong. "

At present, domestic large models are catching up with GPT 4. According to relevant data, GPT 4 needs to be carried out on a single computing cluster with tens of thousands of A100 parallel computers, and the training takes 4-6 months. In the case of limited supply of computing chips, most domestic large-scale model entrepreneurial projects cannot have the same training conditions, which is also the biggest bottleneck of domestic large-scale models at present. However, domestic head cloud service vendors have rich clusters of computing power. From this perspective, the development of large-scale model startups may be constrained by big Internet companies.

It has been reported in the market that after the supply of computing chips was limited last year, the price of cloud services of big Internet companies increased, and the contract prices of some large model startups and cloud service vendors directly increased by 50%. Yang Zhilin, the founder of the dark side of the moon, also mentioned in a recent interview with the media that the price of the machine changed every day for a period of time. "The price has always changed, and the strategy has always changed. There are many different choices from which channel to buy or rent."

From this perspective,Although two large-scale entrepreneurial projects have received a large amount of financing, the biggest winner in the two transactions may also be Ali as an investor."Regardless of the proportion of computing power payment in Ali’s investment in domestic large models, Ali has realized the long-term binding of the project’s demand for computing power clusters and Alibaba Cloud through investment." The above investors told reporters.

It further stated that for the project side, the binding with the Internet giant is a double-edged sword. That is to say, on the one hand, this deep binding may become a constraint to its own development. "On the other hand, the project has very good training resources at once through this binding, and it is possible to launch a better big model than other domestic startups in a short time."

In a recent interview, Yang Zhilin was also asked questions related to Internet giants. Regarding the view that the big model company is finally acquired by the giants, it said in the answer, "Not necessarily, but they may have a deep cooperative relationship. OpenAI and Microsoft are typical cooperation models, and there are many things that can be referenced and some that can be optimized. "

According to the transaction details disclosed by foreign media, a large part of Microsoft’s investment in OpenAI is also paid by force. Other terms include that Microsoft will get three-quarters of OpenAI’s profits until it recovers up to $10 billion in investment; Microsoft’s shareholding in OpenAI is 49%.

Regarding the above investment trends and details, the science and technology innovation board Journal reporter contacted Ali, MiniMax and the Dark Side of the Moon, but no reply was received as of press time.

The competition for domestic big models is fierce

In 2024, Ali’s investment strategy for domestic large models became radical. Some analysts told the science and technology innovation board Journal reporter that,"Wu Yongming is buying a long-term future for Alibaba Cloud through investment."Wu Yongming is the current CEO of Ali Group, Taotian Group and Alibaba Cloud Intelligent Group.

The industry expects that the development of the big model in the future will bring great changes to the field of cloud services. At present, the Internet giants, who are aware of the impending change, have started the competition in cloud services. Overseas giants such as Microsoft, Google and Amazon not only bind AI customers through equity investment, but also actively cooperate with big model startups to broaden the imagination of future cloud business.

Microsoft is undoubtedly the earliest one among them, and it is also the first giant to reap the fruits. Satyanarayana nadella, CEO of Microsoft, previously said in a conference call that more than 18,000 companies are using Microsoft’s Azure OpenAI service, including customers who have never used Azure before. At the same time, many of the revenue growth of its cloud computing product Azure comes from the GPT 4 portal provided by Microsoft.

The above-mentioned analysts told reporters that before, Ali and Tencent’s investment in domestic large models belonged to "spreading water", but at present they are out of differentiation in investment strategy."Tencent has always been hesitant. On the one hand, it may be because the decision-making level has not fully understood the big model and has expectations for its own mixed model. On the contrary, its foreign investment action has slowed down. After the beginning of the year, Ali obviously became more fierce. "

Last year, Ali and Tencent appeared in the same round of financing of Baichuan Intelligent and Zhipu AI. In addition, Tencent launched MiniMax’s A round of financing last year; Alibaba Cloud has invested exclusively in the Angel Wheel.

From the decision-making level, Ali put forward the strategy of "AI+ platformization" two-wheel drive last year; As for Tencent, at the recent Tencent 2023 annual meeting, Ma Huateng said that in the AI field, "We can finally keep up with the first array, which is not the most advanced, but at least it is not too backward. I think we should combine our scenes later and apply the AI ? ? mixed model to various scenes. In a short period of one or two years, I feel that there will not be a pure native AI application, and it should still be integrated into all our products to improve efficiency. I think this is a great opportunity. " Tencent’s own mixed model was unveiled in September last year.

Among the domestic big manufacturers, Baidu, which publicly stated that cloud services have been boosted by big models, was the first to enter the market and lay out big models. The 2023 financial report released by Baidu recently showed that its non-online marketing revenue was 8.3 billion yuan, up 9% year-on-year, which was the highest quarterly revenue in the history of this sector, mainly due to the expansion of its business in intelligent cloud. At the earnings conference call, Li Yanhong said that "the big model brought about 660 million yuan in revenue to the cloud business".

People familiar with the field of cloud services said: "In the future, cloud vendors without the support of the top-level big model may have a difficult competitive advantage."

At the current stage, the advent of Sora model is also stimulating Internet giants to start a new round of AI investment strategy adjustment. Some insiders told the science and technology innovation board Journal reporter that "Byte and Tencent are now looking at the direction of Wensheng video."

　　 More than 80% of human immune function is based on the balance of intestinal flora. Abuse of antibiotics destroys a large number of probiotics and intestinal microecological balance, which creates conditions for the invasion and reproduction of bacteria in vitro.

　　 At present, there are three major problems in antibiotic supervision in China: first, pollution control started late, drug production and use registration system is lacking, and load estimation is difficult; Second, environmental science is out of touch with hydrology, and it is difficult to trace the process; Third, the lack of advanced sewage treatment process makes it difficult to reduce the load.

　　 At present, there is not enough research on the harm mechanism of antibiotics and insufficient supervision on antibiotic abuse in China. We should revise the standard as soon as possible, strictly control the source and strengthen the research to control the antibiotic pollution in rivers, lakes and reservoirs.

　　In recent years, with the continuous promotion of the great protection of the Yangtze River, the water quality in the Yangtze River basin has improved significantly. However, our reporter’s recent investigation found that the concentration of antibiotics in the Yangtze River basin was high and the aquatic ecosystem was destroyed. What is even more worrying is that related surveys show that about 40% of pregnant women in the Yangtze River Delta have detected antibiotics in their urine, and nearly 80% of children have detected veterinary antibiotics in their urine, and some of them have been banned in clinic, which may seriously damage human immunity.

　　Many authoritative experts have called for bringing the threat of antibiotics into the national security monitoring system as soon as possible, strictly controlling the use and discharge of antibiotics from the source, strengthening the research on the impact of pollution on human health, and improving the level of safety prevention and control.

　　Antibiotic pollution destroys water ecology, and the exposure risk of pregnant children increases.

　　The Yangtze River is an important water source, and its water quality is related to the health of hundreds of millions of people. With the rapid industrialization and urbanization of the Yangtze River Economic Belt, the abuse of antibiotics has become increasingly prominent, which not only has a chronic toxic effect on aquatic organisms, but also tends to produce drug resistance and reduce human immunity.

　　A recent survey by the Yangtze River Protection and Green Development Institute of Hohai University shows that the average concentration of antibiotics in the Yangtze River is 156ng/L (ng/L), which is higher than that in some developed countries in Europe and America. The discharge of antibiotics in the lower reaches of the Yangtze River ranks among the top three in China, with an annual discharge intensity of about 60.0 kg/km2.

　　Destroy the ecology of the Yangtze River basin and have a chronic toxicological effect on aquatic organisms. Professor Chen Qiuwen, director of the Institute of Ecology of Nanjing Academy of Water Sciences and director of the Ecological Environment Center of Yangtze River Protection and Green Development Research Institute, found that antibiotics and their metabolites have potential toxicological risks to aquatic organisms such as microorganisms, phytoplankton and fish that are not resistant to drugs, destroying the energy transmission of aquatic food chain, and then affecting the health of high-trophic organisms and aquatic ecosystems.

　　"If the use of antibiotics is not strictly controlled, there will still be a growth trend in the future." Wang Zhiyuan, a senior engineer at the Institute of Ecology, Nanjing Academy of Water Sciences, believes that the "pseudo-persistence" of antibiotic analysis in drinking water sources in the main stream of the Yangtze River can have a chronic toxic effect on aquatic organisms, leading to antibiotics or resistance genes in aquatic organisms. The Yangtze River Delta region has a high intensity of human activities and a large amount of antibiotics, and the situation of antibiotic pollution prevention and control is more severe than that in the middle and upper reaches of the Yangtze River.

　　Children and pregnant women are generally exposed, which destroys human immunity. In recent years, the School of Public Health of Fudan University investigated thousands of children aged 8-11 and 516 pregnant women. The results showed that 21 kinds of antibiotics for human use, veterinary use or human and veterinary use were detected in children’s urine samples, and 79.6% of school-age children detected one or more antibiotics in their urine, some of which were clinically banned. The exposure of veterinary antibiotics was related to children’s obesity and precocious puberty. In addition, 16 kinds of antibiotics were detected in the urine of pregnant women in Jiangsu, Zhejiang and Shanghai, and the detection rate of one or more antibiotics was 41.6%. The exposure of pregnant women was more common and the risk was greater.

　　Professor Chen Qiuwen believes that antibiotics can not be completely metabolized after entering human bodies and animals through drinking water or eating aquatic products. After a long period of intake, antibiotics follow the blood circulation and spread all over many organs, resulting in a gradual decline in immunity.

　　Experts believe that more than 80% of human immune function is based on the balance of intestinal flora. Abuse of antibiotics destroys probiotics in large quantities, which reduces the number of microorganisms sensitive to antibiotics in the gastrointestinal tract, while the flora with poor sensitivity takes the opportunity to multiply in large quantities, which destroys the microecological balance of the intestine and creates conditions for the invasion and reproduction of bacteria in vitro.

　　Two sources of antibiotics: aquaculture materials+medical discharge

　　Our reporter’s investigation found that antibiotics in water mainly come from hospital and pharmaceutical wastewater, aquatic products and livestock and poultry breeding wastewater, and landfill sites. Most antibiotics cannot be effectively removed under the existing technology, resulting in rivers and lakes becoming antibiotic and drug-resistant gene banks.

　　Researchers from the Yangtze River Protection and Green Development Research Institute found in the middle and lower reaches of the Yangtze River that in the process of breeding pigs, broilers and aquatic products, many farmers used to add various antibiotics to their feed in order to reduce the incidence of infection. For example, colistin sulfate and chlortetracycline are commonly used antibiotics in pig feed, and some one ton of feed can add one catty of antibiotics. Some fishery farmers admit: "Antibiotics must be mixed in the feed for raising fish and crabs, or you will definitely lose money if you die."

　　Wastewater from pharmaceutical factories and hospitals contains high concentrations of antibiotics, which causes serious pollution in river basins. The researchers found that there are sewage outlets of large pharmaceutical production enterprises 5 kilometers upstream of some drinking water sources. For example, there are three pharmaceutical companies near the water source in a city in the Yangtze River Delta, and there are six or seven pharmaceutical factories at the intersection of some tributaries of the Yangtze River. The wastewater contains high concentrations of antibiotics.

　　According to the investigation, in recent years, although the Yangtze River Basin has intensified its rectification efforts, many enterprises in the middle and lower reaches of the Yangtze River have moved to the upper reaches or tributaries, and the pollution situation is grim.

　　The latest research by Zhu Yongguan, an academician of China Academy of Sciences, shows that most of the antibiotics ingested by animals enter the soil and water through animal feces and urine in the form of original drugs or metabolites, and they are toxic to the whole ecological environment through the food chain, affecting the normal life activities and functions of plants, soil microorganisms and animals. More seriously, the environmental residue of antibiotics will induce the selection of resistant bacteria, promote the lateral transfer of resistance genes, and lead to the spread of microbial drug resistance. However, microorganisms carrying resistance genes will further multiply when they spread to new environments, and may transfer resistance genes to pathogenic bacteria through the lateral transfer of genes, which will bring disastrous harm to health.

　　Strengthening antibiotic supervision and improving pollution disposal ability

　　Many authoritative experts pointed out that at present, there is not enough research on the harm mechanism of antibiotics and insufficient supervision on antibiotic abuse in China, which leads to the serious high antibiotic content in rivers, lakes and reservoirs.

　　Zhang Jianyun, an academician of China Academy of Engineering and dean of the Yangtze River Protection and Green Development Research Institute of Hohai University, believes that there are three major problems in antibiotic supervision in China: First, pollution control started late, drug production and use registration system is lacking, and load estimation is difficult; Second, environmental science is out of touch with hydrology, and it is difficult to trace the process; Third, the lack of advanced sewage treatment process makes it difficult to reduce the load.

　　"At present, there is a lack of research on the antibiotic exposure of all ages and people, the impact and mechanism of antibiotic exposure on the health of children and people, and the impact of antibiotic exposure from the environment and food on the microbial resistance of people." Professor Jiang Qingwu, former dean of the School of Public Health of Fudan University, said.

　　Relevant experts appealed that the risk of antibiotic pollution is related to people’s health and the long-term development of the Chinese nation. Standards should be revised as soon as possible, sources should be strictly controlled, research should be strengthened, and antibiotic pollution in the Yangtze River basin should be controlled.

　　Strengthen the construction of antibiotic monitoring capacity and revise relevant standards. Academician Zhang Jianyun pointed out that there is still no mandatory standard for the limit value of antibiotic occurrence level in surface water environment, and suggested that antibiotics should be included in the monitoring index in the national water environment monitoring platform for key control sections, and the reference index of typical antibiotics and the limit control index should be added to the current drinking water standard.

　　Reduce the use and discharge of antibiotics from the source. Professor Tang Hongwu, secretary of the Party Committee of Hohai University and executive director of the Yangtze River Protection and Green Development Research Institute, suggested that the mechanism of antibiotic use registration and discharge control should be improved, and a database of antibiotic pollution sources in river basins in China should be established, with emphasis on monitoring key risk sources that contribute a lot to antibiotic load, such as pharmaceutical factories and farms. At the same time, guide aquaculture practitioners to use antibiotics rationally, reduce the dosage, and put an end to the use of banned antibiotics.

　　Strengthen the research on the impact of antibiotic pollution on health and food, and improve the ability of pollution treatment. Professor Jiang Qingwu suggested that the environmental antibiotic residues and human antibiotic exposure and their impact on health should be comprehensively evaluated, with special attention to the impact on children’s growth and development, and the effects and mechanisms of environmental antibiotic residues on bacterial resistance and human health should be studied, so as to provide reliable basic data and theoretical basis for aquaculture, health supervision, food processing and environmental supervision policies.

◎ Our reporter Chen Xi

　　There are endless health-related news on the Internet, but it is hard to tell the true and false "popular science". They are either from an "alternative" interpretation of a netizen, such as negative pressure wards that make patients have difficulty breathing; Or "warm tips" circulating in the circle of friends, such as Flammulina velutipes containing formaldehyde; Or "research results" from professional journals, such as strong chewing ability, not easy to suffer from Alzheimer’s disease, and drinking milk causes cancer … …

　　Today, the reporter of Science and Technology Daily will take stock of these fake popular science rumors in May one by one to help you clear the fog and find the truth.

　　Drinking milk causes cancer? Truth: Without reliable scientific basis, milk is still a healthy food.

　　The saying that "milk and dairy products are carcinogenic" has been widely circulated among the people. Recently, a paper entitled "Dairy products intake of adults in China is related to cancer risk" seems to give this statement "scientific" evidence.

　　This study is aimed at the population in China, and it has followed up 500,000 people in Chinese for 11 years. Relevant research data show that the intake of dairy products is positively correlated with the risk of cancer — — People who regularly eat dairy products have a higher overall risk of cancer.

　　At the same time, the above research data also points out the health benefits of drinking milk, such as promoting growth and development, but it seems that many netizens only care about "drinking milk in Chinese causes cancer".

　　"Academic circles at home and abroad have been talking about ‘ Is milk carcinogenic ’ In recent studies, researchers generally believe that the benefits of drinking milk are the main ones, and this view has the absolute upper hand. Up to now, there is no reliable scientific basis for the claim that milk is carcinogenic, but the benefits of drinking it are very clear. " Professor Wang Huaqing, director of the Cancer Diagnosis and Treatment Center of Tianjin People’s Hospital, said in an interview with the Science and Technology Daily reporter that milk and dairy products are still recommended to the public as high-quality foods in the nutritional dietary guidelines of most countries in the world.

　　Wang Huaqing believes that the key to a healthy diet lies in a balanced diet. "Simply put, it is ‘ Flower ’ Try to eat, you’d better eat more than 12 kinds of food every day and 25 kinds every week. We should not demonize a certain kind of food or deify a certain kind of food. In China’s dietary structure, residents’ calcium intake is generally insufficient. Therefore, the China Residents’ Dietary Guide (2022), which was published not long ago, recommends taking 300 ml to 500 ml of milk or corresponding dairy products every day. " He added.

　　Flammulina velutipes contains formaldehyde? Truth: The pungent smell is produced by Flammulina velutipes itself.

　　Flammulina velutipes is a popular mushroom product, but recently, there have been "popular science" articles in the circle of friends, such as "it has an odor and contains formaldehyde, and vegetable sellers never eat it themselves". According to the article, Flammulina velutipes, which is common in the vegetable market, contains formaldehyde, which not only hurts liver and kidney, but also causes cancer.

　　In this regard, Professor Ban Litong of tianjin agricultural university introduced in an interview with the Science and Technology Daily reporter that some citizens may smell pungent smell when unpacking the packaging bag of Flammulina velutipes. This is not because formaldehyde is added, but because the temperature changes during transportation, which leads to Flammulina velutipes changing from aerobic respiration to anaerobic respiration, and then some volatile aldehyde gases are produced.

　　Some netizens said that formaldehyde was added to Flammulina velutipes for bleaching. In this regard, Ban Litong introduced that Flammulina velutipes was indeed yellow, and the reason why it turned white was not the result of bleaching with formaldehyde. "Today, most of the Flammulina velutipes on the market are new varieties from Japan. Japanese researchers found white Flammulina velutipes with gene mutation in yellow Flammulina velutipes, and then kept it for cultivation. White Flammulina velutipes not only has good color, but also has fast growth speed and high uniformity. " He said.

　　According to the data, China’s Food Safety Law and Agricultural Products Quality Safety Law clearly stipulate that formaldehyde shall not be used as a food processing aid for production and operation. In other words, it is illegal to add formaldehyde to food in any way.

　　Strong chewing ability is not easy to suffer from Alzheimer’s disease? Truth: over-interpretation, there is no causal relationship between the two.

　　Alzheimer’s disease, commonly known as "Alzheimer’s disease", is a chronic progressive brain disorder caused by the damage of brain cells, which mainly affects the function of the brain, and is manifested in memory, daily living ability and other aspects. According to the current clinical data, there is no effective radical cure for this disease. However, a recent hot search in Weibo has aroused widespread concern. According to this Weibo, a study pointed out that chewing ability can predict the risk of Alzheimer’s disease, and the younger the brain, the lower the risk of Alzheimer’s disease.

　　Although chewing ability and Alzheimer’s disease seem to have nothing to do with each other, it seems that someone really found the basis of "chewing is healthier". In 2012, the American Journal of Geriatrics published a study. The study surveyed 557 elderly people aged 77 and over in Sweden. The results showed that the probability of cognitive impairment was significantly higher in people with multiple teeth falling off and hard food chewing.

　　"The above research is only an epidemiological study, which can only show that there is a correlation between masticatory ability and Alzheimer’s disease, but it can’t explain whether there is a causal relationship between them, and its mechanism needs further verification by scientific research." Zhou Yuying, chief physician of tianjin huanhu hospital Neurology Department, said in an interview with Science and Technology Daily that the exact cause of Alzheimer’s disease has not been clearly defined in the medical field, but some risk factors have been confirmed. Age is the biggest pathogenic factor of Alzheimer’s disease, and the risk of Alzheimer’s disease will increase year by year.

　　"Instead of just exercising masticatory muscles to prevent Alzheimer’s disease, it is better to start with the whole lifestyle." Zhou Yuying said, first of all, a healthy diet can control blood pressure, blood lipid and blood sugar, which will have a certain effect on preventing Alzheimer’s disease. Secondly, studies have shown that exercise is very helpful to prevent Alzheimer’s disease, such as walking and running. Hand movements, such as playing the piano, tapping the keyboard and picking up beans, can also effectively stimulate regional cerebral blood flow, which is very helpful to prevent and slow down Alzheimer’s disease.

　　Zhou Yuying said that people who lack hobbies and lead a dull life are more likely to suffer from Alzheimer’s disease, so environmental stimulation is very effective in preventing this disease. Rich life content and social circle can effectively stimulate the cerebral cortex, and "never too old to learn" can also continue to exercise the brain and prevent Alzheimer’s disease.

　　Does the negative pressure ward make it difficult for patients to breathe? Truth: The pressure difference between the inside and outside of the ward is extremely small, which will not cause any discomfort.

　　In many news reports about the COVID-19 epidemic, a word named "negative pressure ward" often appears. In the process of treating COVID-19 patients, the negative pressure ward played an important role, which can be described as a "hero" in fighting the epidemic. However, due to the lack of understanding of this kind of ward, some people only understand it from the word, and then carry out "popular science" on the Internet, saying that "negative pressure will cause patients to have difficulty breathing". What is the truth?

　　"Negative pressure ward refers to the ward where the air pressure in the ward is lower than that outside the ward, which is mainly set for patients with respiratory infectious diseases." Wang Yizhen, the chief physician of the Department of Critical Care Medicine of Tianjin TEDA Hospital, said in an interview with the Science and Technology Daily reporter that the normal atmospheric pressure is 1.013×105 Pascal (pressure unit), while the pressure difference between the negative pressure ward and the normal atmospheric pressure is only 25 Pascal. "This air pressure difference is difficult for ordinary people to detect, and patients will not feel any discomfort in the negative pressure ward."

　　Because the air pressure in the negative pressure ward is lower than the air pressure outside the ward, the air can only flow in one direction, so that when medical staff enter and leave the ward, it can ensure that fresh air from outside can flow into the ward, but the polluted air in the ward will not spread outward. The polluted air will not be discharged at will, but will be collected through special pipes and put in a fixed place, and then discharged to the outside after being filtered and disinfected layer by layer.

On March 1st, the Regulations of Shanghai Municipality on Controlling Smoking in Public Places (Revised Edition) was fully implemented. Smoking is prohibited in indoor public places, indoor workplaces and public transport in Shanghai.

As we all know, smoking is harmful to health! Smoking is an important risk factor for lung cancer, and the mortality rate of lung cancer is 10-13 times that of non-smokers. In the past 10 years, the incidence and mortality of lung cancer have been ranked first in the world. The incidence of lung cancer is also increasing in China, and it has become the first common malignant tumor in cities. Zhou Chao, the chief physician of the Department of Respiratory Medicine of Shanghai Zhou Pu Hospital, gave a lecture on "Early detection and prevention of lung cancer" for the public.

Risk factors of lung cancer

1. Smoking: recognized as an important risk factor, the mortality rate of lung cancer is 10-13 times that of non-smokers; The longer you smoke, the more you smoke, the higher the incidence and mortality of lung cancer. Smoking is not only harmful to smokers’ own health, but also causes many people to become victims of passive smoking, and the harmful substances they inhale are no less than the smokers themselves.

2. Occupational hazards: long-term exposure to harmful environments, such as asbestos, inorganic arsenic, tobacco heating products, etc., including lung cancer caused by asbestos, lung cancer caused by chloromethyl ether, lung cancer caused by coke oven emissions, lung cancer caused by acetate manufacturing, and lung cancer caused by arsenic; Other carcinogenic factors include nickel compounds, polycyclic aromatic hydrocarbons in soot, tar and petroleum.

3. Air pollution: including indoor small environment and outdoor big environment pollution; The incidence of female lung cancer is related to indoor air pollution, such as coal tar, cooking fume and incomplete combustion products in the kitchen ring; Inhalation of secondhand smoke, etc. Outdoor air pollution, such as smog, fuel waste gas, etc., is becoming more and more serious today with increasing industrialization. Inhaling seriously polluted air is equivalent to inhaling more than 20 cigarettes per person.

4. Ionizing radiation: High dose ionizing radiation can cause lung cancer, and different kinds of radiation have different effects.

5. Others: family inheritance, decreased immune function, viral and fungal infection, imbalance between diet and nutrition, etc.

Early symptoms of lung cancer

Especially for those over 40 years old, who have been smoking excessively for a long time, and the smoking index (smoking years × daily cigarettes) is more than 400.

● Irritating cough with no obvious inducement lasts for 2-3 weeks, and the treatment is ineffective.

Low original chronic respiratory diseases, cough nature change.

● Staying with blood in sputum continuously or only for a short time without other explanations.

● Recurrent pneumonia in the same part, especially segmental pneumonia.

● Lung abscess with unknown causes, no toxic symptoms, no large amount of pus and phlegm, no history of foreign body inhalation and no obvious anti-inflammatory effect.

● Unexplained joint pain of limbs and clubbed fingers (toes)

● X-ray localized emphysema or segmental atelectasis.

● Isolated round lesions and unilateral hilar shadow enlargement.

● The original pulmonary tuberculosis and focus have been stabilized, but the shape or nature has changed.

● Pleural effusion without symptoms of infection and poisoning, especially bloody, which increases rapidly.

● Extrapulmonary manifestations: Be alert to the extrapulmonary manifestations of lung cancer.

What are the screening methods for lung cancer?

At present, there are many screening methods for lung cancer, such as chest fluoroscopy, chest X-ray, chest CT, sputum-based cytology, bronchoscopy, fluorescent fiber bronchoscopy and positron emission tomography (PET), but each has its own advantages and disadvantages, and sometimes it needs to be combined and arranged reasonably.

Chest X-ray: It is the simplest and most economical examination method, but its clarity is low, so it is rarely used now.

● Chest X-ray: It is economical and convenient, and it is an important method to diagnose lung diseases, but it has little effect on improving the screening rate of early lung cancer, so it is not recommended to use it alone for early screening of lung cancer.

● Chest CT: It plays an important role in lung cancer screening. Cross-sectional CT imaging completely eliminates the interference of overlapping tissues and surrounding tissues, and has high density resolution. It can detect hidden lesions that are difficult to find on chest plain film, especially for small nodules in the lung, and can find more early lung cancer.

● Radionuclide imaging: Positron tomography (PET) can reflect tumor metabolism earlier and more accurately, which is beneficial to early diagnosis of tumor, understanding the metastasis and recurrence of disease, staging and evaluation of curative effect, but it is expensive.

● Sputum exfoliated cell examination: the first choice to obtain histopathology of lung cancer is non-invasive examination, but there are many factors affecting the positive rate. (Examiner’s technique, tumor type, frequency and quality of examination)

● Bronchoscopy: It can confirm the pathology and the lesion site.

CT-guided transthoracic puncture: cell and tissue biopsy of peripheral lesions.

● Lung biopsy under mediastinoscopy and thoracoscopy: it is also widely used.

Exploration of thoracotomy: sputum, fiberoptic bronchoscopy and transthoracic puncture are negative and can be used. Consider the patient’s age, lung function and surgical complications to weigh the advantages and disadvantages.

● Others: histopathology (metastatic lymph nodes, pleural biopsy, chest puncture), tumor markers, etc.

How to prevent lung cancer

Like other malignant tumors, lung cancer advocates a three-level preventive strategy.

Primary prevention: At present, it is recognized that smoking is the main related factor of lung cancer, so primary prevention should focus on smoking control. We can: strengthen tobacco control legislation and focus on the supervision of smoking ban in public places; Strengthen publicity, improve the awareness of self-health care of the whole people, and change bad lifestyles; Strive to create a smoke-free environment and reduce the damage to passive smokers.

In addition, air pollution and occupational hazards in the working environment are increasingly closely related to the occurrence of lung cancer. In addition to strengthening personal protective measures, it is also necessary for the state to promulgate and conscientiously implement relevant laws to protect the environment on which we live.

For individuals, besides staying away from harmful substances, it is also important to have a balanced diet, live a regular life, combine work and rest, persist in physical exercise, and increase the ability to prevent and resist diseases.

Secondary prevention: early detection of lung cancer patients mainly through chest X-ray, sputum cytology and chest CT; It is necessary to carry out regular check-ups for high-risk groups, such as occupational physical examination.

Tertiary prevention: Generally speaking, the clinical treatment effect of lung cancer is not ideal, and the average 5-year survival rate after diagnosis is only about 10%. The purpose of tertiary prevention measures for lung cancer is to promote recovery, reduce recurrence and complications, prevent disability and tumor metastasis, relieve pain, provide social, psychological and spiritual support, improve the quality of life and prolong the survival period through various comprehensive treatments.

　　Xinhua News Agency, Beijing, June 3 (Reporter Li Heng, Gu Tiancheng) At present, the epidemic situation in China has shown a steady downward trend, but there are still small fluctuations in some areas. How to prevent and control the epidemic situation during the Dragon Boat Festival holiday? How to ensure the safety and order of mass travel? How to guarantee the "vegetable basket" supply of ordinary people? Experts from the State Council Joint Prevention and Control Mechanism recently responded.

　　"All localities should coordinate the prevention and control of holiday epidemics and the normal travel needs of the masses, and scientifically guide personnel to travel safely and orderly." Lei Zheng Long, deputy director of the CDC of the National Health and Wellness Commission and a first-class inspector, said that governments at all levels should effectively compact the responsibilities of the four parties, strengthen epidemic monitoring and early warning, and strengthen the allocation of personnel and equipment in key areas such as airports, stations, docks and public transport.

　　At the same time, relevant departments should do a good job in ensuring mass travel services, set up nucleic acid detection points reasonably, reduce queuing time and avoid people gathering; Scenic spots should also implement the requirements of "limit, reservation and peak shifting" to scientifically and accurately control the flow of people.

　　Lei Zheng Long suggested that people should arrange their travel time and mode reasonably, know the epidemic risk level and prevention and control policies of the destination in advance, avoid going to high-risk areas, reduce large-scale people gathering activities, and ensure that the epidemic will not spread due to holiday travel.

　　"Vegetable basket" products are closely related to the lives of ordinary people and are important livelihood commodities.

　　Earlier, the the State Council executive meeting deployed measures to further improve agricultural production in spring to ensure a bumper grain harvest and a stable supply of important agricultural products; The Ministry of Agriculture and Rural Affairs and the National Health and Health Commission issued the "Guidelines for Coordinating the Prevention and Control of Epidemic Situation in COVID-19 and Agricultural Production in Spring", clarifying that in areas where there is no epidemic situation, it is strictly forbidden to set up checkpoints without authorization, arbitrarily open roads and close villages, and prevent farmers from going to the fields on the grounds of epidemic prevention; Eleven departments, including the Ministry of Agriculture and Rural Affairs and the National Development and Reform Commission, demand that every effort be made to stabilize the production and supply of "vegetable basket" products, take various measures to unblock the transportation channels of "vegetable basket" products, and make full use of the docking mechanism of "vegetable basket" products & HELIP; …

　　"Looking at all aspects, the current production situation of meat, eggs, milk, fruits, vegetables and fish in China is good, the total supply is sufficient, and the market remains stable, which can fully meet the consumption needs of urban and rural residents." Song Danyang, deputy director of the Department of Market and Information Technology of the Ministry of Agriculture and Rural Affairs, said that the Ministry of Agriculture and Rural Affairs and relevant departments have repeatedly dispatched and deployed production urgently, strengthened monitoring and docking, organized key wholesale markets to increase the supply of "vegetable basket" products in Shanghai and Jilin, and mobilized e-commerce enterprises to give priority protection to areas with serious epidemics, and included agricultural products and agricultural production materials in the scope of key transportation materials.

　　"Dragon Boat Festival holiday in China ‘ Shopping basket ’ The market supply of products is fully guaranteed and the price is expected to remain basically stable. " Song Danyang said that in the next step, the Ministry of Agriculture and Rural Affairs will work with relevant departments to guide all localities to implement differentiated prevention and control measures, ensure the orderly development of agricultural production, further compact the mayor’s responsibility system of "vegetable basket", and do their best to ensure stable production and supply.

　　Vaccination in COVID-19 is the basis of epidemic prevention and control, which can form a better protective barrier.

　　As of June 1st, the national cumulative report of vaccination in COVID-19 exceeded 3.38 billion doses. The number of people over 60 years old covered by vaccination reached 230.21 million, 218.252 million people were vaccinated in the whole process, and 169.135 million people were vaccinated.

　　"The overall vaccination work in COVID-19 is progressing smoothly." Lei Zheng Long said that some provinces have actively explored ideas and accumulated more experience in vaccination work, and the National Health and Wellness Commission has promoted these experiences to all provinces, requiring all localities to further compact their responsibilities, carefully organize and effectively promote vaccination.

You obviously bought a member, but you have to spend another 50 yuan?

On December 11th, Joy of Life launched "Advance Point Screening" on Tencent and iQiyi at the same time, and VIP members can submit it to 50 yuan and watch 6 episodes in advance.

Yes, even if you are a VIP, you have to pay 50 yuan again (if you are not a VIP, you have to do a VIP first).

I believe that the audience is no longer unfamiliar with this operation. In 2019 alone, The Untamed’s "The Moon Shines on My Heart" and "You Without Secrets" and other dramas have started "VVIP". Recently, soso’s "Once upon a time there was a Mountain with a Sword" also adopted the mode of "paying to see the ending in advance".

Such a "re-payment" model has undoubtedly triggered the audience’s spit:

Some people have even started to promote "resources" online.

Some viewers made such a reaction, and the platform could not have been unexpected before launching the "advance screening". So why does the platform still adopt such a model? How many viewers will really pay for this?

2.5 million people are willing to "be leeks"?

As a male drama, Joy of Life has a lot of "sand sculpture" plots. From the setting of crossing at the beginning to the appearance of Guo Qilin (yes, that’s Fan Sizhe), a lot of funny plots are released in the play.

In addition to the plot, many characters in the play are also very lovable. Teng Zijing died to save Fan Xian, which triggered a heated discussion among the audience. Wang Juan even became a "screenwriter out of the circle" and was drawn into Joy of Life’s fan base, which also showed the audience’s love for the plot.

FUNJI data shows that "plot" is the hottest entry in the short comments of Douban, and the number of discussions has reached 173 times.

Douban data shows that Joy of Life scored 8.0, and the number of commentators has exceeded 82,000.

These data and public opinion indicate that Joy of Life has a very high degree of heat. But are these enough to support Joy of Life’s "price increase by relying on heat"?

You know, The Untamed’s comments on Douban reached 666,000, which is eight times that of Joy of Life. Although there is a time factor, The Untamed didn’t pay again until the last five episodes of the series. Compared with the practice of paying in Joy of Life’s plays, he was relatively less anxious.

More importantly, due to the theme and cast, The Untamed attracts the attention of younger female users, and these users are more willing to pay. Tmall data shows that the post-90s generation has become the backbone of social consumption in China, and the "Double Eleven" in recent three years,After 1995, the consumption accounted for more than 50% of the total, and in 2018 it reached 67%.Similarly, this group of people is also the main group supporting content payment, among which the female group is the "top priority".

According to statistics, The Untamed’s audience born after 1995 accounts for about 48%, and female users account for 81%. Such a fan composition also allows The Untamed to play a series derivative. Among them, the ticket price of Nanjing concert caused a sensation, and the ticket price of "a row of tickets in the venue" was even speculated by scalpers to the sky-high price of 151 thousand tickets.

Such data also led to The Untamed’s excellent performance in the "VVIP" mode. Although there is no official data, it was pointed out in a TV program that the platform made a profit of 75 million yuan a day by The Untamed’s "re-payment", which means that a total of 2.5 million people paid for watching the ending in advance (the fee for watching the last five episodes of The Untamed in advance was 30 yuan).

After 10 days of charging, a total of 2.67 million people paid, and the estimated fee is nearly 80 million. It can be found that most payers will pay immediately after the emergence of the New Deal to avoid being spoiled. I am afraid that there are not a few fans who pay for it while spitting on the platform.On the other hand, in Joy of Life, Joy of Life is only 29% and 63% respectively, which is about 20% behind The Untamed.

For this reason, as well as platform competition and other factors (Joy of Life is co-broadcast by Tencent and Iqiyi, and The Untamed is broadcast by Tencent alone), Joy of Life has offered 50 yuan /6 episodes (6 episodes can always be given priority in the process of watching 6 episodes first and 19 episodes later), which seems to be cheaper than 30 yuan /5 episodes (6 yuan/episode) in The Untamed.

At present, Tencent and Iqiyi have not released the relevant data of "re-paid" users, but it can be predicted that Joy of Life will not catch up with The Untamed in terms of payment.

Can "VVIP" become the norm?

In addition to The Untamed and Joy of Life, You Without Secrets (21-32 episodes, 4 episodes ahead of 18 yuan), The Bright Moon Shines on My Heart (31-36 episodes, 6 episodes ahead of 12 yuan) and Once upon a time, There was a Mountain with a Sword (33-37 episodes, 5 episodes ahead of 12 yuan) were also shown in advance to varying degrees.

From the platform point of view, all of these dramas have Tencent videos, and most of the dramas are based on the route of "sweet pet love" and "sand sculpture funny", and most of the fans are aimed at the consumer groups such as young women. From the current drama ideas of major platforms, this part will occupy a large proportion for a long time.

It can be expected that after tasting the sweetness, the future platform is likely to "intensify". It may become the norm for fans to "pay the bill while spitting".

Of course, too much "advance projection" will bring more moral dilemmas and public pressure to the platform. However, in a strict sense, "advance screening" is in line with the laws of economics, fans have the need to look ahead, and it is understandable that the platform provides services, which is essentially a consensual transaction. This model is similar to the principle of selling "queue-jumping tickets" (that is, playing without queuing) in Disneyland.

Compared with the moral dilemma, the greater threat the platform faces may be the reduction of piracy costs.Piracy resources that used to need to be completed by all kinds of technologies may now be available for only 30 to 50 yuan, and then selling them at a low price (for example, 50 yuan buys them, 2 yuan sells them alone, and small profits but quick turnover) will become a new way of piracy. This will not only affect the profit of "advance click", but also endanger the VIP income of the platform.

In fact, in addition to the platform, we can also see the changes of fans from the popularity of "advance screening". Specifically, the needs of fans are showing more levels. In addition to "chasing drama and chasing love beans", the social monetary value of film and television dramas has also increased again and again.

When everyone in your office has bought an advance screening and started talking about the latest hot drama, normal drama chasers will only look out of place. The audience who watched the advance screening can’t wait to get their own comments on social media, and the overwhelming comments will only further reduce the patience of ordinary viewers. It is precisely by grasping this psychology that "advance screening" can be so successful.
