CCTV News:Neihuang County, Anyang City, Henan Province, is a traditional agricultural county in the northern plain of Henan Province. Since 2009, Neihuang County has invested in a large-scale ceramic industry and introduced a number of ceramic enterprises, which has brought about a ceramic industrial park with an annual output value of more than 10 billion yuan. Business is booming and the industry is booming, which is a good thing, but the local people have been calling the media to complain about the pollution caused by the ceramic industrial park in the village recently, and the people are complaining.

　　UAV shoots ceramic industrial park at an altitude of 200 meters.

　　On March 12, 2018, the reporter came to Neihuang County, Henan Province. In order to verify whether there was any pollution problem in the local ceramic industrial park, the reporter used a drone to shoot the ceramic industrial park in Neihuang County at an altitude of 200 meters. As far as the eye can see, there are many factories and bare white powder piled up everywhere. Neihuang Ceramic Industrial Park is the largest ceramic production base and product distribution center in the Central Plains. The industrial park is divided into two parts, one is the production area and the other is the sales area. Although the production enterprises have not started, the business of large and small ceramic tile sales stores is still very prosperous. Sales staff told us that most of the tiles sold by these stores came from the production enterprises in the park. During the conversation, the reporter hoped to know whether ceramic tile production would pollute the environment. Unexpectedly, the salesperson answered directly.

　　Sales staff of ceramic industrial park in Neihuang County, Henan Province: "The pollution is not small, because there is no way to eat groundwater now. When the country stops production, our side stops during the day and produces at night."

　　The surrounding area of the ceramic park looks like a fire scene from afar.

　　In order to find out the truth, the reporter conducted an investigation in and around Neihuang County Ceramic Industrial Park for several days. Finally, on the evening of March 20th, the reporter smelled a strong and pungent smell around the ceramic park, which was suffocating. The company named "Langer Ceramics Co., Ltd." emitted huge smoke. Even in the night, the smoke was extremely amazing, thick and thick, looking from a distance, like a fire scene, and the air was filled with the choking smell of kerosene.

　　Sewage forms a colorful oil stain on the river.

　　The Xiaohe River is the only river in Neihuang County. On the morning of March 21st, the reporter noticed that the "white" sewage was continuously discharged into the river through a drain. These discharged "white water" have foam on the surface and an unpleasant smell. These are the two outlets under the Xiaohe Bridge, and the sewage has formed a colorful oil stain on the river. We walked along the section of the Nitrate River passing through the ceramic park and found that there were seven similar outlets in total. Some villagers who work in the ceramic factory told reporters that the wastewater generated in the ceramic production process will first be discharged into the sewage pool of the factory, and then slowly seep into the ground. Every rainy day, we will "take the opportunity" to discharge it into the nitrate river next to the ceramic park along the rainwater pipeline.

　　Pollution causes crops to fail to collect groundwater.

　　What impact does the pollution caused by ceramic enterprises have on local people? The reporter saw in an interview with Xiaotun Village, the nearest village to the west side of the ceramic industrial park, that the villagers told us about their experiences one after another. Near the ceramic industrial park, the wheat began to turn yellow.

　　Local villagers: "The wheat is too small to be obvious, the pepper is obvious, the fruit is on top, and the wheat is wrapped in a shell. It was obvious as soon as the ceramic factory started. The smoke it emits is glazed in the factory, and the corn is covered with white powder, which is the same as frost. It doesn’t bear ears, and red peppers don’t bear peppers. "

　　The crops in the fields near the ceramic factory are almost never harvested.

　　The villagers told reporters that in recent years, almost all the crops in the fields near the ceramic factory have been harvested every autumn. In the eyes of the villagers, the "culprit" that caused the grain harvest was the "smoke" coming out of the chimney of the ceramic factory. Besides air pollution, the local people are more afraid of the water discharged from the ceramic factory. In the village of Dadikou, which is just across the river from the ceramic park. The groundwater in the village has been polluted, and the water quality of the well water, which was originally clear and bright, has become worse and worse, and it can only be used for washing clothes or feeding animals. As a last resort, the villagers can only go far and near, and dig wells from other villages dozens of miles away. In this villager’s home, he specially pumped a bucket of water from his well more than 30 meters deep.

　　The groundwater is dirty, and there are oily floating objects on the water surface.

　　In order to prove to the reporter that the pollution he suffered was absolutely true, the villager deliberately burned a pot of hot water. Just after heating, the reporter found that a layer of floating objects like oil stains appeared on the water surface, and a lot of scale appeared at the bottom. During the investigation, the reporter visited several villages around the ceramic industrial park. The dirty groundwater can be seen everywhere, and the groundwater in Xizhangbao Village, located on the east side of the ceramic industrial park, has also been seriously polluted. The staff of Guardian Ceramics Co., Ltd. admitted that there was water pollution in the park.

　　Ceramic factories issue "pollution fees" according to the distance.

　　In addition, during the interview, the villagers all mentioned a "pollution fee" issued by the ceramic factory. They told reporters that according to the distance between each field and the ceramic factory, the ceramic factory subsidizes the expenses ranging from 20 yuan to 100 yuan per mu.

　　Reducing cost to avoid "coal to gas" sewage treatment is not up to standard

　　In fact, the environmental protection department has clearly stipulated the emission limits of pollutants such as sulfur dioxide, nitrogen oxides and particulate matter in ceramic industrial enterprises. Then, have the production enterprises in Neihuang County Ceramic Industrial Park strictly implemented the emission standards of pollutants in ceramic industry and installed environmental protection facilities such as desulfurization, denitrification and dust removal?

　　salesman: "One of our factories, the smallest one, has to use 300 to 400 tons of coal. If it is a big factory, it has to reach the concept of 500 to 800 tons. Air pollution, smog and desulfurization will not work, and it will also exceed the standard. You can desulfurize during the day, and I’m still discharging at night. This thing, there is no way, if you want to reduce costs, you can only do this. "

　　Cost-reducing enterprises steal sewage at night

　　The salesperson who claimed to be Neihuang Jiade Ceramics Co., Ltd. told the reporter that in order to reduce costs, enterprises can only use night smuggling. However, if clean energy natural gas is used, it is relatively easier to meet the requirements in the standard, but it will inevitably lead to an increase in the cost of tiles. According to insiders’ calculation, if "changing coal into gas" is implemented in Neihuang production area, the production cost of ceramic enterprises will increase by 18%, and the cost of a tile will increase by 50 cents. For cost reasons, up to now, there are still many ceramic enterprises in Neihuang Ceramic Park that have not changed from coal to gas.

　　Besides the potential waste gas pollution, how do the ceramic factories in Neihuang Ceramic Industrial Park treat their production wastewater? This is a report in Henan Daily in 2016, which clearly reads: "The sewage treatment project in the south of Neihuang City, with an investment of 28 million yuan, can treat 5,000 tons of sewage every day, which can basically meet the sewage treatment needs of ceramic parks. While promoting the transformation and upgrading of the ceramic industry, the project has also achieved both economic and environmental benefits." Two years have passed, has this sewage treatment project with an investment of 28 million yuan been completed, and is it treating industrial wastewater generated by ceramic factories? With all kinds of questions, the reporter came to Bishuiyuan Sewage Treatment Plant in Neihuang Ceramic Park.

　　The staff of several sewage treatment plants told reporters that this sewage treatment plant was put into operation in the second half of 2017. Due to the limitations of the process, it was only responsible for treating the domestic sewage in the ceramic factory. As for where the industrial wastewater generated by the ceramic factory went, they did not know.

　　Functional departments shirk environmental pollution and lack supervision

　　The reporter learned in the Neihuang County Water Affairs Bureau that in the Neihuang County Ceramic Industrial Park, the drain that the reporter saw was not built by government departments, but was built privately. The staff of the Neihuang County Water Affairs Bureau also suggested that the reporter report to the Environmental Protection Office of the Ceramic Park. According to the address provided by the staff of the Water Affairs Bureau, the reporter found the "Zhongyuan Porcelain Capital Environmental Protection Institute".

　　As soon as I entered the door, the reporter thought I was in the wrong place, and the environmental inspection department was located in the marketing hall of the ceramic production enterprise. As an environmental volunteer, the reporter met the person in charge of "Zhongyuan Porcelain Capital Environmental Protection Institute". In the face of a reporter’s question, the person in charge of Zhongyuan Porcelain Capital Environmental Protection Institute told the reporter that the responsibility of Zhongyuan Porcelain Capital Environmental Protection Institute is to check the sewage discharge and air pollution of production enterprises, but when the reporter reported that the enterprise had secretly discharged sewage and secretly built sewage outlets to discharge industrial wastewater directly into the river as an environmental volunteer, the person in charge said that they were "unaware" of the number of sewage outlets under the Xiaohe Bridge and the pollution situation. Neihuang county monitors the groundwater around the ceramic park every year, and has never found any pollution problems. In the face of such an answer, the reporter suggested that it was less than one kilometer from the enterprise to the "Zhongyuan Porcelain Capital Environmental Protection Institute", hoping to take environmental inspectors to check it on the spot, but I didn’t expect it to be rejected by the staff of the Environmental Protection Institute.

　　During the interview, the villagers told reporters that since nearly 90% of the laborers around the ceramic factory are working in the factory, on the one hand, they are polluted hometown, and on the other hand, they are worried about the future, and more are helpless.

　　villager: "Ceramic factory has certain advantages and disadvantages. The advantage is that there is a place to work and earn money, so you don’t have to go out, especially for women. The downside is that the pollution is too strong. "

　　On the one hand, it is a polluted environment, and on the other hand, it is an important source of local tax revenue. Which is more important? This is indeed a multiple-choice question before the local people and the local government. However, a good ecological environment is the fundamental foundation for the sustainable development of people and society. I hope the local government can do this multiple-choice question well, and don’t destroy the homes of future generations for the sake of immediate achievements and immediate interests.

Guo Liang was an early proletarian revolutionary of our party, a famous leader of the workers’ movement, and a close comrade-in-arms who organized and led the workers’ movement with Mao Zedong. Mao Zedong praised him as "a famous organizer of the workers’ movement". On March 29th, 1928, Guo Liang was secretly killed by Kuomintang reactionaries in Qianping, Simenkou, Changsha, at the age of 27. In Guo Liang’s short life, although there are not many poems left behind, they show Shi Ce’s unyielding heart and courage to fight.

"Ask the society, what is the truth?"

Guo Liang, formerly known as Guo Jing Jia, was born in 1901 in Wenjiaba, Sheshan, Tongguan Town, Wangcheng County, Hunan Province (now Guo Liang Village, Tongguan Street). At the age of 11, he changed his name to Guo Liang, hoping to be as resourceful as Zhuge Liang. When Guo Liang was a teenager, he paid close attention to the poor life of the people who were hungry and toiling, and thought deeply about it. He wrote a sharp new-style poem "Ask the Society": A strange question is not worth mentioning by scholars and juren, and it is also common sense for teachers, but they know nothing about it! Where did the Gu Mi of the rich come from? Why do farmers carry grain into the rich man’s barn? Ask the society, what is the truth? Where did the rich man’s house come from? Why do poor people build houses and rich people live in peace? Ask the society, what is the truth? Where do the clothes of the rich come from? Why don’t people who grow cotton and weave clothes cover their bodies? Ask the society, what is the truth? People live in the same world, why are the rich and the poor different? Ask the society, what is the truth? This poem tells the people’s sufferings in plain language and lashes out at social injustice in extremely sharp language, which is particularly easy to resonate and soon spread.

It is also in order to answer these doubts in Ask the Society that Guo Liang read more and more historical books, cared about his family and country, and began to explore the truth actively. In the autumn of 1915, 14-year-old Guo Liang was admitted to Changjun Middle School. With the anti-Japanese patriotic struggle of Hunan people constantly emerging, Guo Liang participated in the patriotic anti-Japanese struggle of Changsha students. In 1916, Guo Liang saw the heads of the murdered revolutionaries on the streets of Changsha, and angrily chanted poems: "How much blood and tears are there?"? Revenge needs to pour water into the cave, and patriotism can’t be afraid of hanging its head! " Grief and indignation gushed out from this poem, and the patriotic fire took root in the young man’s heart.

"A trickle of water sinks into a huge stream"

Once the patriotic fire is lit, it burns in Guo Liang’s young chest. He sympathized with the sufferings of the people and helped the poor to destroy their homes. In the process of dealing with the masses, I also deeply felt the turbulent but confused revolutionary enthusiasm. It seems that Guo Liang, who is surrounded by mountains and mountains, is eager to explore the way of struggle and the direction of progress. In 1919, Mao Zedong founded Xiangjiang Review in Changsha to spread and introduce new ideas. Guo Liang, who has been trying hard to explore the road of saving the country and the people, was struck by Mao Zedong’s article and soon became a loyal reader of Xiangjiang Review. In 1920, Guo Liang was admitted to Hunan No.1 Normal University, and met Mao Zedong by chance. From then on, he often asked Mao Zedong for advice on how to reform the society. Introduced by Mao Zedong, Guo Liang joined Xinmin Society, and then participated in Hunan Marxist Research Association organized by Mao Zedong, He Shuheng and Fang Weixia. In the practice of struggle, Guo Liang began to have a clear revolutionary ideal and struggle ideas, and firmly believed that nothing could be done without transforming the country.

In the winter of 1921, introduced by Mao Zedong, Guo Liang joined the Communist Party of China (CPC) and became one of the earliest party member in Hunan. When joining the party, Guo Liang made a generous statement: "Some people just give an empty mouth, and I, Guo Liang, are willing to give my head to the party." Guo Liang, who joined the Communist Party of China (CPC), finally belonged, and wrote a poem to express his feelings: "A trickle of water sinks into a huge stream, and it turns around without stopping; The back waves push the front waves and fly over the mountains to be free. " He compared his personal strength to a trickle, which, once put into the arms of the Party organization, converged into stormy waves and condensed into a majestic force of revolutionary struggle under the guidance of party flag.

"When will I wash away all my worries?"

After gloriously joining the Party, Guo Liang became more and more mature in thought, and more and more deeply realized that only by mobilizing millions of working people to work together can the action of saving the country have a steady stream of power. In the summer of 1922, after graduating from Hunan No.1 Normal School, Guo Liang immediately joined the revolutionary movement. In August of the same year, appointed by Mao Zedong, Guo Liang went to Yuezhou to carry out the work of Guangdong-Han railway labor movement. When he sailed down the Xiangjiang River to Dongting Lake, he was full of thoughts and couldn’t help chanting, "Xiao Shui, Xiang Shui, flows into the Yangtze River without a head." Long Jun sent me Dongting water, when will I wash away all my worries? " Guo Liang knew that the trip was bumpy and arduous, but he had no time to think about the severity of the difficulties, but immediately devoted himself to the fiery labor movement. On September 9th, Guo Liang organized and led a strike of 3,000 workers on the Guangdong-Han Railway, which shocked the whole country and opened the prelude to the first labor movement climax in Hunan. At the end of the same year, Guo Liang led the kindling of the workers’ movement to his hometown Tongguan. In the struggle, Guo Liang made good use of concise language to complain about the sufferings of ceramic workers, such as: "Digging clay bent his waist, pushing clay bowed his back, burning kiln goods burned his heart, making kiln goods worn his hand, and selling kiln goods lost his leg." In a few words, the injustice of the poor life of ceramic workers for generations was revealed, which aroused the workers’ resonance, condensed the struggle force, led the ceramic workers to resist the so-called "kiln door tax" and organized the establishment of the Tongguan ceramic trade union. On the day when the Tongguan Ceramics Trade Union was established, the Hunan District Committee of the Communist Party of China sent a pun couplet. The first part is "Don’t say that loose sand can’t make a great instrument", and the second part is "You should know that soil can turn into gold".Highly praised Guo Liang for leading generate, a ceramic worker.

In leading the Guangdong-Han railway workers’ strike, the pottery workers’ struggle against taxes and taxes, and the Changsha workers’ struggle against imperialism and feudal warlords, Guo Liang has increasingly demonstrated his ability to approach and inspire the masses. At that time, Bolshevik, the central theoretical publication, commented on Guo Liang: Guo Liang was the pioneer of Hunan workers’ movement. Anyuan in Jiangxi, Shuikoushan in Hunan, Changsha, Guangdong, Han and Zhuping in Hunan, Hubei and Jiangxi provinces, these local workers and other industrial professional workers all organized struggles under his direct and indirect guidance.

"Heroes have never bowed their heads since ancient times."

"Xiang water stirs up the hatred of the river, and the sword breaks the water and flows more. Although good and evil are reversed, heroes have never bowed their heads since ancient times. " This poem was sung by Guo Liang on the way to Wuchang after he was arrested by the enemy. It not only expressed his resentment of "the inversion of good and evil", but also showed his heroic spirit of being fearless and dying. In July, 1924, after Guo Liang was elected as the chairman of Hunan Anti-Imperialism Alliance, he wrote a lot of campaign articles. Under the careful organization of Guo Liang, Hunan once again set off an anti-imperialist climax. Guo Liang, who was at the forefront of the struggle, was wanted several times by Zhao Hengti, the warlord of Hunan at that time. In the face of the wanted notice, Guo Liang laughed it off without fear, and wrote a doggerel: "Zhao thief is persistent, a man looks like a wolf, killing with one hand and burning incense with the other, shouting autonomy and secretly communicating with the powers. If this cub is not removed, the people will suffer, and they will get a dog’s head and a pair of copper coins. Advise the police, don’t be fooled, help the tiger eat, and it will come to no good end. The notice is integrated, so remember to be detailed. " This limerick exposes the ugly face of reactionaries in laughing and cursing, and also points out the direction of struggle for the people in plain language. Under the leadership of Guo Liang and other comrades, anti-imperialist and patriotic activities in Hunan have become increasingly frequent and powerful. Facing the great revolutionary situation, Guo Liang and his comrade-in-arms Xia Minghan touched the scene and recited poems. Guo Liang recited: "One sword hangs on the bedside, and the GREAT GHOST kid comes in." Xia Minghan replied, "Kill all demons and level the world, and the mountains, rivers, the sun and the moon will be rearranged." The two revolutionary heroes expressed their aspirations with poems, and their determination to fight to the end jumped to the page.

In January 1928, dispatched by the CPC Central Committee, Guo Liang served as the secretary of the special committee of Hunan, Hubei and Jiangxi. Under the leadership of his organization, the party organizations in the border areas of Hunan, Hubei and Jiangxi provinces have been restored and developed. On March 27th, Guo Liang was arrested in Yueyang because of a traitor’s informer, and was executed secretly by the reactionary authorities in the early morning of 29th. Before his execution, he wrote a cone-shaped suicide note to his wife, who is also a native of communist party: "Can Ying, my love: Bright running around, homeless and stateless. I’m done. Hope to be kind and caress my son to follow my ambition. This is awkward. " This touching suicide note not only expresses deep attachment to family members, but also expresses infinite expectations for future generations to continue their struggle.

In the new version of Dietary Guidelines for China Residents (2016), the first core recommendation mentions cereals: there are various foods, and cereals are the main ones. What does the grain include? Where is the whole grain? How much grain should we eat every day? Today, Xiaobian will give you a "past lives" of grain.

What is whole grain?

Whole grain refers to the whole grain and its natural nutrients that have not been refined (or processed by grinding and crushing). Compared with refined grains, whole grains contain more B vitamins, minerals, dietary fiber, phytochemicals, tannins, carotenoids, phytic acid, lignin and lignans. Common varieties are grain amaranth, barley, buckwheat and so on. "Whole grain" retains all kinds of nutrients and active ingredients in the grain to the maximum extent, and its health effects in preventing chronic diseases and other fields are remarkable.

How much grain do you want to eat every day?

Dietary Guidelines for China Residents (2016) suggests that healthy adults should consume 250g-400g of cereals and potatoes every day, which is equivalent to 1 small bowl of rice or 1 medium-sized steamed bread per meal. The whole grain and miscellaneous beans are not less than one third (50-150g).

What are the benefits of eating whole grains often?

According to the data of the Whole Grains Council of the United States, eating whole grains regularly can effectively reduce the risk of some chronic diseases, such as type 2 diabetes by 21-30%, cardiovascular disease by 25-28% and stroke by 30-36%. It can also reduce the risk of obesity, colorectal cancer, asthma and inflammatory diseases, maintain normal blood pressure, reduce gum disease and prevent tooth loss.

How to select whole grains

1. According to the suggestion of USDA, firstly, check whether there is the word "whole" in the ingredient list, such as whole oats, whole wheat flour, whole grain corn and whole rye.

2. Even if some foods are marked with "multi-grain", "100% wheat", "high-fiber" and "whole wheat", in fact, they are only added with bran, lacking germ, and do not belong to whole grains, so they need to be carefully recognized when purchasing.

3. When choosing oatmeal, try to choose "pure oatmeal" instead of "nutritious oatmeal" with various ingredients, such as white sugar and vegetable oil powder. "Pure oatmeal" contains higher nutrients, such as dietary fiber, and more sugar and fat in "nutritious oatmeal" is not conducive to cardiovascular health.

Because of the aging immune system, vaccines are less effective for the elderly. Scientists believe that it is more important and more widely used to develop drugs that can enhance the immune function of the elderly than to develop vaccines for the elderly.

Along with skin aging, there is also the immune system. | Figure worm creativity

Author | Doctor of Immunology, Zhao Bei

Recently, many deaths caused by influenza vaccine in Korea have attracted attention. As of October 31st, the death toll rose to 83, of which 71 were over 70 years old (accounting for 85.5%). In addition to the possible quality problems of the vaccine itself, it also reminds us of the fact that the role of the vaccine for young people and the elderly is different.

This is also a difficult point in the development of COVID19 vaccine.

Increasing age, and aging immune system

As people get older, we experience a series of physical changes, such as hearing loss, skin relaxation, joint injury and so on, and even the vitality of the immune system gradually decreases. This phenomenon is called "immune aging". This is also the reason why the elderly have become the main targets of infection and death in Covid-19.

In the face of the out-of-control epidemic in COVID-19, USA, and the emergence of the second round of epidemic peak in Europe, vaccine research and development is in full swing in various countries, which is expected to be a life-saving straw to reverse the situation.

However, vaccines, a means of "actively mobilizing the human immune system to prevent real virus attacks", are usually far less effective in the elderly population-the immune response of the elderly to vaccines is often weaker. That is, the immune system of the elderly is more difficult to be mobilized by vaccines.

This means that vaccines may not protect those who need protection most.

So, how does the immune system age?

Our bodies are naturally resistant to most pathogens. Although the environment is full of pathogens, we still live well most of the time.

The human immune system is divided into innate immunity and acquired immunity. The former is universal immunity. When the body encounters foreign objects (such as skin and mucous membrane), innate immunity will respond quickly. However, although it responds quickly, its ability is limited and it is often broken. For example, when it meets Covid-19, it can’t hold on.

The latter is the acquired immunity of the body, that is, for some pathogens that have not been seen before, the body must first fight with it and learn from it before it can gain immunity to it. The power of acquired immunity is very powerful. As long as the body can withstand the attack of pathogens in "learning" and meet the same pathogens in the future, it will not be a problem at all. For example, infectious diseases such as smallpox and chickenpox, if you get it once, you will generally not get it again.

When the body is invaded by foreign pathogens, such as viruses, innate immunity and acquired immunity will cooperate to resist.

In the innate immune system, immune cells, such as phagocytes and natural killer cells, will recognize or even devour the virus first, and secrete a large number of cytokines to summon more immune cells with different functions to join the battle. Some of these cells, such as phagocytes and dendritic cells, will also transmit the antigens of these viruses (substances that can cause antibody production) to the subsequent T cells and B cells, which are representatives of acquired immune cells.

T-cells and B-cells (shown here as antibodies produced by B-cells) are representatives of immune cells, and they are named after mature parts. The former is mature in thymus (English) and the latter is mature in bone marrow (English). Both are star immune cells. | Figure worm creativity

These two kinds of cells can not only produce antibodies and cytokines to quickly destroy the virus, but also form specific memory cells, so that they can respond quickly after encountering the same virus again.

When the immune system destroys the virus, immune cells will gather locally in the body, forming redness, swelling and heat pain, which is what we usually call inflammation. Proinflammatory factors secreted during this period, such as interleukin -1 and tumor necrosis factor α, can promote the elimination of pathogenic microorganisms, but excessive inflammation may lead to cytokine storms and even life-threatening. Another kind of anti-inflammatory factor, such as interleukin -10, can prevent excessive inflammation and maintain the balance of the body environment.

These factors together constitute our immunity.

And what will happen to our immune function as we get older? What is the impact on vaccine development?

Compared with young people, the immune aging of the elderly is mainly manifested in two aspects:

The initial number of T cells and B cells decreased. Vaccine mainly stimulates B cells to produce antibodies. Only when there are a large number of B cells with high diversity of receptors in the body, the greater the probability of recognizing antigens, and the targeted (directional) antibodies and memory B cells can be formed. -The decrease of B cells will undoubtedly weaken this effect.

Chronic low-grade inflammation is easy to occur after vaccination. The aging and necrotic cells in the elderly can not be removed in time, which will stimulate the immune system continuously, causing immune cells (such as macrophages) to continuously secrete pro-inflammatory cytokines, and the immune response cannot be terminated. The consequence is that the immune system can’t respond the next time the pathogenic microorganism attacks the human body, that is, immune dysfunction.

These lead to different effects of vaccines in the elderly and young people.

Vaccine research and development under "immune aging";

A special vaccine or an auxiliary drug to reverse aging?

For Covid-19, there are about 50 kinds of vaccines being tested in the world, but scientists are still not sure whether the vaccines are equally effective for the elderly.

One of the vaccines "mRNA-1273" being developed by Moderna, a biological company located in Cambridge, Massachusetts, USA, produced antibody levels similar to those of younger subjects in 40 subjects over the age of 56.

However, Pfizer and BioNTech, pharmaceutical companies located in Mainz, Germany, found in the first phase of the experiment that the antibody level induced by the vaccine "BNT162b2" was only half that of young people. It is certain that the antibody level produced by the elderly after vaccination is higher than that caused by the virus infection of their peers, but this is still not enough to explain whether the antibody induced by "BNT162b2" is enough to protect the elderly from the real virus attack.

Most of the vaccines being developed have elderly subjects, but more than half of the 18 latest candidate vaccines have no elderly subjects in clinical trials, which greatly increases the potential risks of vaccines to the elderly.

Some vaccines are being developed, which may have hidden dangers for the elderly. | Figure worm creativity

Facing the phenomenon of immune aging of the elderly, scientists are also actively looking for strategies.

Mainly includes the following two aspects:

(1) The first is how to enhance the immune response of the elderly induced by vaccines.

According to the experience in the research and development of influenza vaccine, the elderly are usually treated by increasing immune stimulating components (such as adjuvants) or increasing the dose of virus antigen to achieve the expected antibody level.

Other scientists have turned to developing drugs to enhance the immune system function of the elderly, that is, supplementing drugs at the same time of vaccination. This way aims to promote the rejuvenation of the immune system of the elderly, even reverse immune aging, and can also resist the virus more effectively when it is infected.

In the above two schemes, the research on reversing age, especially immune aging, has made some progress. In the past 20 years, scientists have found some key small molecular targets. One kind of anti-aging drugs acts on the protein molecule mTOR in the cell growth regulation pathway. Experiments show that inhibiting the expression of mTOR can prolong the life of Drosophila and even mice.

Joan Mannick, one of the founders of resTORbio, a biotechnology company in Boston, Massachusetts, USA, said that "mTOR participates in many biological regulation mechanisms, especially the process of human aging and organ dysfunction".

During his work at Novartis Institute in Cambridge, Massachusetts, Mannick published a study on mTOR protein in 2018, trying to answer the question "Can reducing the content of mTOR protein in the elderly improve the immune system function of the elderly?". 264 participants in the study received low-dose mTOR inhibitor or placebo respectively, and after six weeks, the infection rate of influenza virus and the effect of influenza vaccine were followed up. It was found that the number of people suffering from influenza in the elderly who received mTOR inhibitors decreased significantly, and the immune response caused by influenza vaccine was stronger.

Another study shows that mTOR inhibitor RTB101 can enhance the immune response of the elderly after coronavirus infection, and the elderly who receive mTOR inhibitor have lower coronavirus load and recover faster. At present, resTORbio is testing the preventive or therapeutic effect of RTB101 on Covid-19 infection in 550 elderly people over 65 years old in nursing homes.

In addition, at least four research teams are studying the therapeutic effect of rapamycin, another more mature mTOR inhibitor, on the elderly over 60 years old infected with COVID-19.

In addition, metformin, a drug for the treatment of type 2 diabetes, also inhibits the activity of mTOR protein. Clinical data from China and the United States show that diabetic or obese patients who take metformin have less symptoms of Covid-19 infection and lower mortality.

Carolyn Bramante, a researcher at the University of Minnesota in the United States, pointed out that people with diabetes and obesity show immune deficiency very similar to that of the elderly. At present, Bramante and his colleagues are conducting a study involving 1,500 people to explore whether taking metformin can prevent Covid-19’s infection or alleviate its symptoms. Although the mechanism is not clear, decades of clinical data show that metformin has high safety, can be used in children and even pregnant women, and the cost is very low, which are the advantages of metformin.

(2) The second key is how to avoid causing or how to terminate chronic inflammatory reaction.

Studies have found that losmapimod, an anti-inflammatory drug used to treat muscular dystrophy, can inhibit chronic inflammatory response and improve the body’s response when viruses or bacteria invade. A biological company in Cambridge, Massachusetts, USA recruited 400 volunteers to verify the therapeutic effect of losmapimod on patients with COVID-19. The drug may be able to treat symptoms such as respiratory failure after Covid-19 infection, thus saving patients’ lives.

Many scientists say that it is more important to develop drugs to enhance the immune function of the elderly than to develop COVID-19 vaccine for the elderly, and the latter is more universal, which can improve the protection effect of influenza vaccine, COVID-19 vaccine and even other vaccines in the future. A deep understanding of immune aging and its regulation mechanism and the development of related drugs will also have far-reaching implications for the treatment of other diseases such as diabetes and cancer.

In short, although there are always difficulties in vaccine development, known or unknown, scientists have been working hard and believe that methods will always be found.

Original title: "Immune aging that cannot be underestimated: old age may lead to ineffective vaccines"

Read the original text

Special feature of 1905 film network In the last shot, Tommy Tam handcuffed himself with Leslie Cheung’s handcuffs, and also handcuffed the originally broken Song brotherhood back; After 31 years, the first official poster is two handcuffed hands, and behind it is still about brotherhood.

　

*Intertextuality between the Final Scene of Hero and the Poster of Chasing.

　

Last Friday, "The True Color of Heroes" was released for more than 30 years, and it was restored for the first time in mainland China, and it monopolized 20 million box office in just three days. Many people go into the cinema to relive this classic Hong Kong film, perhaps for the sake of "brother" Leslie Cheung, perhaps for the sake of Mark with a long trench coat, or perhaps for the sake of enjoying John Woo’s violent aesthetics exclusively.

　

　

Then this Friday, the film Chasing officially landed in the cinema. This film is a Chinese gun battle film made by John Woo after 25 years. After the series, the master of violent aesthetics has gained more tenderness, which seems to be more appropriate to describe with his own debut, and it is a kind of "iron man’s tenderness" temperament.

　

Chasing is a master’s idolize

　

"I have always admired Gao Cangjian very much." Wu Yusen has said this sentence for more than ten times.

　

　

This sentence is not simply for film promotion, but a master’s heartfelt recognition of the actor superstar. In the early days, John Woo started to use Chow Yun Fat, just because of his similar temperament with Gao Cangjian. Even in the modeling of the film, letting Chow Yun Fat wear sunglasses and a trench coat is a tribute to Gao Cangjian.

　

It’s just a pity that John Woo, who has cooperated with Tom Cruise, Ben Affleck, Nicolas Cage and other first-line Hollywood actors, has never been able to form a cooperation with Gao Cangjian. Now, it is in memory of Gao Cangjian that the present Hunting is produced.

　

* The original "Crossing the River of Anger"

　

In fact, the process of winning the copyright of Hunting is also very bumpy. As the Japanese film "Chasing" was unwilling to sell the film copyright, Huanya directly bought the copyright of the original novel "Crossing the River of Anger" and found Wu Yusen, hoping to complete a new adaptation with his personal style. The views of both sides just fit, so this work came into being.

　

　

After all, the adaptation of this version of the story has become the most "difficult" thing. The original novel is a story that happened in the 1960s, and many events and events are out of date for the present. At the same time, there are also concerns that the audience will compare the two versions of the film. As a result, a team of seven screenwriters led by Chen Jiashang adapted the whole story into an escape story in a modern city.

　

Although from the film title signature, neither the scriptwriter, editor nor producer belongs to Wu Yusen, but the content style is still another extension of his "violent aesthetics", and the iconic symbols such as "Double Heroes" and "Dove" are all available.

　

After watching John Woo’s works in different periods for two weeks, I can feel that Wu Dao seems to have changed, but he seems to be the same John Woo who can successfully make Hollywood commercial movies.

With the popularization of HPV vaccine knowledge, many people want to be vaccinated with HPV vaccine. But how much do you know about HPV vaccine? What is the difference in the applicable population of HPV vaccines with different "prices"? In this regard, Chen Shouzhen, deputy director of the Obstetrics and Gynecology Hospital affiliated to Fudan University, summed up ten common questions and answered them to the majority of netizens.

What is HPV virus?

Human papillomavirus (HPV) is a small double-stranded DNA virus, so it is called human papillomavirus because it only infects humans. There are more than 200 subtypes of HPV, which can be divided into high-risk type and low-risk type according to whether they are carcinogenic or not.

Low-risk type usually infects the skin and causes warts, commonly known as boils. Most of them can naturally subside in 3-5 years, and some may need laser, freezing and other methods to remove them.

There are about 15 HPV subtypes (HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, 73 and 82) that can cause malignant tumors such as cervical cancer, vaginal cancer and oropharyngeal cancer, so they are called high-risk HPV. Among them, HPV16/18 has the highest risk of cancer. About 70% of cervical cancer in the world is caused by high-risk HPV16 and 18, and 20% is caused by HPV31, 33, 45, 52 and 58. HPV16 types 16 and 18 are also associated with oropharyngeal cancer, vulvar cancer, vaginal cancer, penile cancer and anal cancer.

Will HPV infection definitely lead to cancer?

Persistent infection of high-risk HPV will lead to cancer. More than 90% of HPV infections usually subside naturally within 2 years. If carcinogenic HPV infection lasts for more than 1 year, the possibility of precancerous or cancerous lesions will increase, but not all persistent infections will progress. Only less than 1% of infections will develop into cancer after 5 to 10 years of precancerous lesions. Therefore, even if there is HPV infection, it will not necessarily become cancer, but we should pay attention to the corresponding screening.

At present, there is no specific drug to treat HPV. Through regular screening, we can observe the situation of HPV infection, so that we can treat it at an appropriate time and reduce the risk of cancer.

Personal life is very healthy, how can you be infected with HPV?

HPV virus spreads in various ways.

It can be widely spread among people through skin contact, and more than 80% of women have been infected with HPV at least once in their lives. Sexual life is the main reason why HPV spreads around the anus and genitals. Sticking to the correct use of condoms can reduce the risk of HPV infection.

Generally speaking, there are many ways of HPV infection. At present, there is no good way to prevent HPV infection, but healthy living habits, such as quitting smoking and drinking, and wiping separately after going to the toilet may reduce the probability of HPV infection. Even if you are infected with HPV, you don’t have to be nervous, because most HPV infections can be monitored regularly after infection, and generally will naturally fade away soon.

How to prevent HPV transmission?

Vaccination with HPV vaccine can safely prevent cancer caused by persistent HPV infection.

Vaccination with tetravalent or nonavalent HPV vaccine can also prevent condyloma acuminatum, which is a benign disease, but the treatment failure rate is relatively high, affecting physical and mental health. Therefore, for the majority of women, it is very necessary to vaccinate HPV vaccine.

How to choose HPV vaccine?

At present, three different vaccines have been developed, which are divided into bivalent, tetravalent and nonavalent vaccines according to the number of HPV subtypes they target. Simply put, bivalent HPV vaccine is aimed at HPV types 16 and 18; The tetravalent HPV vaccine is aimed at HPV6, 11, 16 and 18; The nine-valent HPV vaccine not only targets the same HPV subtype as the four-valent vaccine, but also targets types 31, 33, 45, 52 and 58. At present, HPV vaccines are all preventive vaccines, aiming at preventing initial HPV infection and subsequent HPV-related diseases.

At present, many hospitals, from community medical service centers to tertiary hospitals, have HPV vaccines, and these HPV vaccines can be safely vaccinated. Because of limited resources, the queue time of nine-valent vaccine will be longer. If resources and funds are not a problem, it is recommended to vaccinate the nine-valent HPV vaccine. If there is no nine-valent HPV vaccine, tetravalent HPV vaccine and bivalent HPV vaccine are also good choices, because both vaccines cover the most dangerous types 16 and 18. Generally speaking, you should try to use the same vaccine preparation to complete vaccination. However, if you don’t know the original HPV vaccine dosage form, you can also use another HPV vaccine preparation to complete the subsequent vaccination.

At what age is it appropriate to get HPV vaccine?

At present, the recommended age of HPV vaccination in China is 9-45 years old. Most countries in the world recommend routine HPV vaccination at the age of 11-12, and some suggest starting from the age of 9. For teenagers and adults aged 13-26, replanting is also recommended if they have not been vaccinated with HPV vaccine or have not completed a series of vaccines.

Why don’t foreign countries recommend routine replanting for adults over 27 years old? This is because with the increase of age, the possibility of infection with subtypes covered by HPV vaccine is gradually increasing. For older people, the benefit and cost performance of HPV vaccination are low. However, research shows that there are two peaks of high-risk infection among women in China: 17-24 years old and 40-44 years old, and single HPV infection is the main infection. Considering the characteristics of female infection and the low coverage rate of cervical cancer screening, experts suggest that women aged 9-26 should be vaccinated with HPV, and women aged 27-45 should be vaccinated when conditions permit. Women over the age of 45 don’t have to worry. At this stage, the HPV vaccine is low in cost performance, and the standardized HPV screening is enough to prevent cancer.

In the recommended age range, the best time for HPV vaccination is before the first sexual intercourse, because HPV vaccine immunization is the most effective for individuals who are not infected with HPV. That is to say, the younger you are when you are vaccinated with HPV, the more the incidence of cervical cancer decreases.

Are there any side effects of vaccination?

Vaccination of HPV vaccine, like other vaccines, may have pain, swelling and erythema at the inoculation site. A few people may have syncope or dizziness, and there are some rare other side effects, which may be related to the adjuvant in the vaccine, so you can rest assured to vaccinate. In addition, HPV vaccine can be safely inoculated in different parts with other vaccines at the same time. At present, there is evidence that inoculation of tetanus, acellular pertussis, diphtheria and inactivated polio vaccine at the same time with HPV vaccine does not damage the immune effect of the body against HPV vaccine or other vaccines at the same time.

Because there is no relevant evidence, it is generally not recommended to vaccinate HPV during pregnancy. However, with the increase of the number of people vaccinated, more and more data about unintentional vaccination after pregnancy show that vaccination during pregnancy has no effect on the safety of mother and child. Nevertheless, the remaining vaccination should be postponed, and it is best for vaccinated women to get pregnant two months after the vaccination is completed. Vaccine does not affect the safety of breastfeeding, but at present, such data are limited, so it is necessary to carefully consider HPV vaccination for lactating women.

I have been infected with HPV before, can I still be vaccinated?

There is no need to evaluate whether you have been infected with HPV before vaccination. A history of abnormal cervical cancer screening, genital warts and HPV infection is not a taboo for HPV immunization. Because these conditions all suggest that HPV was infected in the past, but it is not necessarily HPV subtype infection covered by HPV vaccine. For people who have a history of HPV infection but are still within the recommended age range, vaccination is still recommended because it still has a protective effect on the uninfected vaccine strain HPV virus. However, for people who have been infected with the subtype covered by HPV vaccine, the benefits of immunization are small.

What if we miss the seeds? I have been vaccinated with bivalent or tetravalent HPV vaccine before. Do I need to replant with nine-valent HPV vaccine?

Missing seeds means that immunization is not carried out according to the schedule. At present, the evidence shows that no matter how long the series vaccination is interrupted, it can continue to vaccinate without restarting the series vaccination.

Now it is found that HPV vaccine has a long-lasting protective effect against HPV-related diseases, and there is no need for multiple cropping. For women who have already completed bivalent or tetravalent HPV vaccination, the benefit of using nine-valent vaccine for multiple inoculation may not be obvious, so it is not recommended.

After vaccination with HPV vaccine, can I avoid regular screening?

At present, HPV vaccine can only prevent infection. After vaccination, existing HPV infection, genital warts or precancerous lesions cannot be eliminated, and the vaccine can only prevent cervical cancer caused by seven subtypes at most. After injection of HPV vaccine, other subtypes of HPV may still be infected, which may lead to cancer. Therefore, cervical cancer screening is still needed after HPV vaccination.

On the evening of March 19th, the 2023 performance report was disclosed.

In 2023, the operating income reached 372.6 billion yuan, up 5.0% year-on-year, and the net profit returned to the mother reached 8.2 billion yuan, up 12% year-on-year, achieving double-digit increase for seven consecutive years; The return on net assets reached 5.1%, achieving a good level in recent years; The capital expenditure is 73.9 billion yuan, and the network investment shows an inflection point.

Over the past year, we have focused on the coordinated development of the two main businesses, successfully achieved effective improvement in quality and reasonable growth in quantity, and laid a solid foundation for long-term development.
