CCTV News:Recently, at the meeting of the Dispute Settlement Body of the World Trade Organization held in Geneva, Switzerland, the United States was convicted of violating WTO rules, but instead, the United States used the arbitration institution to "shut down" to appeal and tried to shelve the execution of the ruling indefinitely, which was severely denounced by many WTO members.

At the closed meeting held on January 27th, five members, namely China, Norway, Switzerland, Turkey and Hong Kong, China, set eight topics, demanding that the plenary session adopt five rulings of the expert group on the violation of the new regulations on the origin marking of Hong Kong goods imposed by the United States on imported steel and aluminum products under Article 232, and demanding that the United States cancel the illegal measures. The United States appealed all five rulings before the meeting.

But in fact, since 2019, the United States has repeatedly unilaterally obstructed the selection of judges of the WTO Appellate Body, and the WTO Appellate Body has fallen into a state of complete paralysis after the expiration of the previous judge in November 2020.

According to the minutes of the meeting published by the WTO, the permanent representative of the European Union to the WTO said at the meeting that the WTO arbitration institution was "paralyzed" because of deliberate sabotage by the United States, and it was impossible to hear these appeals at present, and the United States was actually abusing its right of appeal. Abuse of the right of appeal does not help to resolve trade disputes.

The Permanent Representative of Canada to the WTO said at the meeting that all parties to trade disputes must make every effort to find acceptable solutions and fulfill their good faith commitments under the Understanding on Dispute Settlement Rules and Procedures. The suspension of the Appellate Body has brought unfairness and short-term advantages to some members.

　　　　　　 The Permanent Representative of China to the WTO said that it seems that the United States will refuse to implement any unfavorable ruling involving "national security exception", which violates the principle of "pacta sunt servanda". These disturbing behaviors in the United States clearly depict the image of the implementer of unilateral bullying, the destroyer of multilateral trading system and the disruptor of global industrial chain supply chain.

　　　　　　 What is the ruling of the United States to appeal this time? In December 2022, the WTO released the report of the expert group on the dispute settlement mechanism, ruling that the measures taken by the United States to impose tariffs on imported steel and aluminum products in 2018 violated WTO rules and suggested that the United States should correct them. In March 2018, then US President Trump imposed tariffs of 25% and 10% on imported steel and aluminum products on the grounds of safeguarding national security according to Article 232 of the US Trade Expansion Act of 1962. This decision not only led the countries concerned to file a complaint with the WTO, but also the major trading partners of the United States introduced retaliatory measures. In November 2018, the WTO Dispute Settlement Body agreed to set up an expert group to review the steel and aluminum tariff measures announced by the United States to confirm whether the measures violated WTO rules. It was not until last December that the expert group of WTO dispute settlement mechanism issued its ruling.

　　　　　　 The unilateral trade bullying behavior of the United States has aroused more and more opposition around the world. Some media commented that the United States has now become the biggest destroyer of the international trading system.

　　　　　　 Headquarters reporter Yi Xin:For a long time, the United States has been waving a trade stick at other WTO members on the grounds of "national security" and frequently violated WTO rules. The research report on WTO dispute adjudication shows that by far, the United States is the most "unruly", and two-thirds of WTO violations are caused by the United States. When the WTO expert group ruled that the United States violated the rules, the United States took advantage of the current deadlock in the appointment of members of the WTO Appellate Body to appeal the ruling, so as to evade its obligations. The WTO Appellate Body’s "shutdown" and the paralysis of multilateral trade arbitration institutions are precisely caused by the United States’ insistence on obstructing the selection of judges despite the opposition of more than 100 WTO members. At the US trade policy review meeting held by the WTO in December last year, many WTO members expressed serious concern and dissatisfaction with the US trade policy.

Convicted of violating WTO rules, instead of executing the ruling, the United States appealed by using the "shutdown" of the appellate body, trying to put the execution of the ruling on hold indefinitely.

As an arbitration institution for trade dispute settlement, the Appellate Body is known as the "jewel in the crown of WTO" and it is an important part of the WTO dispute settlement mechanism. It has seven permanent seats for judges, each of whom has a term of four years and can be re-elected once. According to the WTO, cases of trade disputes must be tried and decided jointly by three judges. If the number of judges is insufficient, they can’t accept any new cases, and they will fall into a state of "stopping".

One of the most prominent features of the Appellate Body of WTO is its independence. Under this mechanism, all 164 WTO members, regardless of their size, can obtain equal rights to appeal or defend themselves. However, it seems that the United States has always regarded itself as an exception and repeatedly abused the "one-vote veto" to arbitrarily obstruct the start of the selection process for new judges of the Appellate Body.

Since 2017, the United States has frequently blocked the start of the selection process for new judges of the WTO Appellate Body.

In 2017, three of the seven judges of the Appellate Body ended their terms, but the United States has always blocked the appointment of new judges. Counting this time, in the past two years, the United States has said no to the selection of new judges for 30 consecutive times.

In 2018, the United States vetoed the appointment of Mauritian judges for a second term by one vote, leaving only three judges in the WTO Appellate Body. Three people are also the bottom line for the appellate body to operate. In order to avoid the "lockout", in that year, 67 WTO members demanded that "the selection process for new judges of the Appellate Body should be started as soon as possible". However, the United States rejected this proposal.

In November 2019, at the regular meeting of the WTO Dispute Settlement Body, 117 WTO members once again suggested that the process of selecting new judges of the Appellate Body should be started immediately, which showed the strong political will of most members to restore the Appellate Body. However, the United States is still bent on its own way.

On December 9, 2019, the United States once again unilaterally obstructed, resulting in a draft resolution on the reform of the Appellate Body not being passed, and the selection of new judges was once again blocked.

Due to the inability to select new judges in time, from December 11, 2019, only one judge of the Appellate Body was in office, and the Appellate Body was in a state of "stopping".

　　　　　　 On November 30, 2020, the last member of the Appellate Body officially expired. At this point, all members of the Appellate Body have left their posts.

What is the core reason for the United States to do so in the face of non-implementation of WTO rulings, non-compliance with rules and deliberate sabotage? What kind of bad influence will it have? Let’s listen to the interpretation of special commentator Su Xiaohui.

Su Xiaohui, a special commentator, said that many countries see that the United States has a kind of "double standard" behavior towards rules, and they will use it if they agree, and abandon it if they disagree. At the same time, they will try their best to safeguard American hegemony by taking the leading role in rule-making and use American bullying in trade. This kind of behavior interferes with the development of the world economy and harms others, which is also the fundamental factor behind everyone’s rebound against the United States.

On January 10 th, a book called"Stop issuing performance pay scheme for COVID-19 project"The document was circulated on the Internet and signed by Beijing Kexing Zhongwei Biotechnology Co., Ltd., which mentioned that the company’s COVID-19 vaccine has been completely discontinued and the company has no COVID-19 vaccine products for sale at present.

At noon on January 10th, Jimu journalist called the product consultation hotline of Kexing Holding Biotechnology Co., Ltd., and the staff confirmed it.Kexing’s COVID-19 vaccine has been discontinued. If you still need to inject this product, you should ask the local CDC if it is in stock.

It is worth noting that there are still a variety of vaccines for new strains that can be injected in various parts of China.

Kexing COVID-19 vaccine has been discontinued.

Many companies have "got off the bus" before.

According to Jimu News, on January 10th, a document named "Stop Issuing Performance Pay Scheme for COVID-19 Project" was spread on the Internet. The date of signing the scheme was January 9th, and it was stamped with the official seal of Beijing Kexing Zhongwei Biotechnology Co., Ltd., which mentioned that at this stage, the company has stopped production of COVID-19 vaccine and the company has no sales of COVID-19 vaccine products at present, and the company decided to stop issuing performance pay for COVID-19 project for existing employees from January 2024.

Beijing Kexing Zhongwei Biotechnology Co., Ltd. is a subsidiary of Kexing Holding Biotechnology Co., Ltd. At noon on January 10,The staff of the product consultation hotline of Kexing Holding Biotechnology Co., Ltd. confirmed that at present, the COVID-19 vaccine of Kexing of the company has been discontinued. If the product needs to be injected, it is necessary to ask the local CDC if it is in stock.As for the authenticity of the online transmission of "Stop Sending Performance Pay Scheme for COVID-19 Project", the other party said it was unclear, and she was only responsible for product consultation.

In fact, since 2023, a number of companies that have been developing COVID-19 vaccine have either announced a change of direction or stopped investing, or their financial data reflect the "sequela" of "slow sales" of COVID-19 vaccine.

On July 19th, 2023, COVID-19 Microorganism Tianci Factory, one of the three musketeers of domestic mRNA vaccine, suspended its trial operation because there was no demand for vaccine production in the near future. All this was only two and a half years after it obtained the clinical approval of COVID-19 mRNA vaccine in January 2021. At that time, COVID-19 mRNA vaccine of Microorganism was the second domestic COVID-19 mRNA vaccine that entered the clinical stage.

For COVID-19 vaccine, Clover Bio, a Hong Kong-listed company, can be described as "putting all your eggs in one basket". In June, 2022, Clover Bio announced that it would give priority to the allocation of all resources to COVID-19 vaccine project, suspend the investment in the other three clinical pipelines, and reduce the investment in non-COVID-19 projects and new projects. In December 2022, COVID-19 vaccine SCB-2019(CpG 1018/ aluminum adjuvant), a recombinant protein of clover, was put into emergency use in China, and was officially launched for the first time in February 2023.

However, in the semi-annual report of 2023, Clover Bio said that due to the ever-changing and low overall demand for COVID-19 vaccine from China and countries around the world since 2023, the company predicted that COVID-19 vaccine sales in 2023 would not bring meaningful financial contribution. Its vaccine layout turned to respiratory diseases such as RSV and influenza.

In April 2023, the "low-cost operation notice" of Shangyao Kangxinuo was spread on the Internet. The content of the notice shows that it is decided to suspend the production line from April 4 for a period of 180 days. According to Red Star News at that time, the staff of Kangxinuo patient answering hotline introduced that the COVID-19 (vaccine) production line here was temporarily suspended, and there was no problem here at the headquarters. Now the demand for COVID-19 vaccine is not so great, so the production line of Shanghai Kangxinuo COVID-19 (vaccine) has been temporarily stopped, which will not affect other aspects.

Chang Rongshan: Inactivated vaccine is not recommended at present.

In February 2023, a research paper published by domestic researchers in the latest issue of China CDC Weekly stated that,"Although the protective efficacy of the third dose of Kexing inactivated vaccine can be improved to more than 70% within one month after homologous inoculation, its predictive efficacy will gradually decline to less than 50% after six months."

For COVID-19 infected people whose clinical endpoint is "COVID-19’s symptoms", the research results show that after 28 days and 6 months of intensive immunization, the protective effect of three doses of inactivated Kexing vaccine is only about 30% and 10%. Among them,The predicted protective effect of three doses of Kexing inactivated vaccine on Omicron BA.4/5 is even lower.

According to the interface news, virologist Chang Rongshan reminded that,Inactivated vaccine is not recommended at present.It pointed out that the antigenicity of the current epidemic strains has changed greatly, and the effect of inactivated vaccine will be much worse than that of other technological vaccines."It is best to play mRNA vaccine and recombinant protein vaccine."

According to JingJing. com, Xu Yue, an insider of a company that had previously researched and developed vaccines in COVID-19, said, "The research and development cost is one aspect, but the key is that you have developed it, and the virus has mutated, so the research and development speed can’t keep up at all. Vaccine iteration is too fast, and enterprises really can’t afford it, especially the cost of clinical trials. Before it is commercialized, the vaccine will be outdated first. "

Xu Yue told reporters that unlike the flu virus, which may go round and round, Covid-19 has been upgrading all the way, and the popular virus will not come again, and the old virus will not come. Therefore,Once the new COVID-19 vaccine appears, the old vaccine can be said to be "out of the historical stage".

A number of XBB vaccines were approved for use.

However, people’s willingness to vaccinate has obviously decreased.

According to Jingjing.com, on December 28th, 2023, the National Health and Wellness Commission held a press conference on the prevention and treatment of respiratory diseases in winter. Peng Zhibin, director of the Department of Respiratory Infectious Diseases of the Infectious Diseases Management Office of China CDC, said that recently, the spread of JN.1 (the second-generation sub-branch of BA.2.86 mutant in Omicron, Covid-19) has risen rapidly abroad and has become the main epidemic strain.

"The mutant JN.1 belongs to Omicron. Recently, according to the existing evidence, the World Health Organization believes that JN.1 has strong transmission ability and immune escape ability, but there is no evidence to suggest that its pathogenicity is enhanced. Previous infection and vaccination with XBB (Omicron subtype variant strain) vaccine have a cross-effect of immune protection, and it is predicted that the public health risk brought by it is low. " Peng Zhibin said.

At present, many XBB vaccines have been approved for emergency use in China. In June, 2023, the recombinant trivalent Covid-19 (XBB+BA.5+Delta mutant) trimer protein vaccine (hereinafter referred to as WEEK XBB vaccine) was put into emergency use in a certain range. In December, companies such as Shenzhou Cell, Kangxinuo and Livzon Group also announced that COVID-19 vaccine was included in emergency use.

According to the interface news, a domestic vaccine industry practitioner said,At present, the proportion of people’s willingness to vaccinate COVID-19 vaccine has obviously decreased, and the official has not clarified the requirements for vaccination indicators.All this makes "promoting vaccination in COVID-19" less urgent than before, which reduces the motivation of CDC. He said, "For example, if a company has a product approved, as long as it is developed and produced, the company will definitely want to be recognized in the market, and there is no situation in which the company is not enthusiastic. But in fact, from the step of bidding access, many provinces and cities have no enthusiasm. "

Rong Shan, a virologist, also said that the public is not willing to vaccinate COVID-19 vaccine at present. If COVID-19 vaccine is purchased, but not many people come to vaccinate it, it will easily lead to a backlog. Unlike ordinary commodities, vaccines have strict requirements for transportation and storage, and they will be wasted if they are not used after expiration.

Original title: Kexing COVID-19 vaccine has been discontinued! Many companies have long since "got off the bus", inactivated vaccines have not been recommended, and many XBB vaccines have been approved.

　　Xinhua News Agency, Chengdu, March 20th Question: Have you found the answers to all the N kinds of legends about Sanxingdui?

　　Xinhua News Agency reporters Wang Peng, Shi Yuxi and Tong Fang.

　　With the announcement of new archaeological discoveries in Sanxingdui site, people’s eyes once again focus on this magical land.

　　Since the discovery of No.1 and No.2 "sacrificial pits" in Sanxingdui site in 1986, people have never stopped discussing it. A large number of shocking and mysterious cultural relics unearthed in the "sacrificial pit" have aroused a lot of speculation in the world.

　　Have you found the answers to those legends about Sanxingdui?

　　Legend 1: Is Sanxingdui an alien civilization?

　　Sanxingdui bronze vertical mask (Xinhua News Agency)

　　Huge ears, bulging eyes, and a big mouth wide to the ears … … Some people who eat melons believe that Sanxingdui is an alien civilization, and the grotesque bronze masks, bronze statues, bronze sacred trees and other cultural relics of Sanxingdui are alien works.

　　Experts are firmly opposed to this statement! The ancient Shu civilization, represented by Sanxingdui, is an important part of the pluralistic origin of Chinese civilization. Among the cultural relics unearthed in Sanxingdui, bronze statues, bronze rings, jade Zhang, jade cong, jade bi and jade ge are consistent with the Yellow River basin, which shows that Sanxingdui has the common attributes of Chinese culture. The familiar cultural relics with strange shapes and magnificent atmosphere, such as bronze standing man, bronze sacred tree and bronze vertical mask, not only show the brilliance of ancient Shu civilization, but also show the richness and diversity of Chinese culture.

　　In other words, Sanxingdui civilization is "made in China" and has nothing to do with aliens.

　　Legend 2: Sanxingdui people "moved" to Jinsha?

　　The gold mask unearthed from Jinsha site (left) and the newly discovered gold mask in Sanxingdui (imposition picture)

　　The newly discovered gold mask of Sanxingdui "made a stunning appearance", and the sharp-eyed netizens saw at a glance: this is the same as the gold mask of Jinsha! Not only the gold mask, but also the ornamentation, jade Zhang, jade chisel, ivory &hellip on the golden crown belt of Jinsha and the golden staff of Sanxingdui; … There are many cultural relics in the two sites. So can we think that people from Sanxingdui "moved" to Jinsha?

　　Experts believe that this high similarity between Jinsha site and Sanxingdui site proves that they belong to the same cultural system, and there must be some special connection between the two sites. Combined with the archaeological findings in recent years, we can think that Jinsha culture is the inheritance and development of Sanxingdui culture, and both of them have become an important part of the development of ancient Shu civilization.

　　Legend 3: Sanxingdui Archaeological Excavated "Angry Birds" with the same pig?

　　"Angry Birds" with the same pig (Xinhua News Agency)

　　Just last July, Sichuan Institute of Cultural Relics and Archaeology announced that an important site — — Joint site, unearthed a large number of cultural relics. Among them, a clay pottery pig is cute and cute, which is very similar to the villain green pig in Angry Birds. Netizens exclaimed: Is this the predecessor of Angry Birds?

　　In fact, experts believe that the joint site of this clay sculpture pottery pig unearthed should be an important settlement around the ruins of Sanxingdui ancient city. The joint site covers four cultural factors, namely, Guiyuan Bridge, Baodun Bridge, Sanxingdui Bridge and Twelve Bridges. It is the first time that a complete sequence of ancient Shu civilization has been found around Sanxingdui. Among them, the main cultural factors of Sanxingdui are the most abundant in the joint site, and a large number of cultural relics similar to Sanxingdui have been unearthed.

　　There are not only "villain green pigs", but also a large number of high-handled beans, hollowed-out beans (plates) and small flat-bottomed cans have been unearthed and restored at the joint site. It is worth mentioning that the pottery with the combination pattern of dragons and phoenixes carved on the yinxian line was unearthed in the late Shang Dynasty, and it is the earliest pottery with the pattern of "dragons and phoenixes are auspicious" found in China.

　　Legend 4: The "bronze giant" holds a "selfie stick" in his hand?

　　Sanxingdui "Bronze Man" (Xinhua News Agency)

　　Among the numerous bronze statues in Sanxingdui, the "bronze giant" is well known. Its overall image is solemn and solemn, and its hands are hollow. For a long time, people have been speculating whether he holds some kind of instrument in his hand. Even naughty netizens think that he is holding a "selfie stick" in his hand.

　　At present, there is no final conclusion on this issue in academic circles. Experts discussed that the "bronze standing man" may hold ivory, jade cong or scepter. The "Bronze Big Liren" wears a high crown, narrow sleeves and a half-arm-style three-layer dress, with complex and exquisite clothes, mainly dragon patterns, supplemented by bird patterns, insect patterns and eye patterns, and plaid stripes. It seems that his identity is an ancient Shu "high priest" with extraordinary skills.

　　There is no end to the exploration of Sanxingdui civilization.

　　Up to now, archaeologists have unearthed more than 500 important cultural relics in the six Sanxingdui cultural "sacrificial pits" newly discovered at Sanxingdui site.

　　I believe that in the future, through the detection and analysis of these cultural relics, more puzzles about Sanxingdui will be revealed. The true face of this ancient civilization, which has been buried deep underground for 3 thousand years, will become more and more clear.

　　We will wait and see … …

　　Throughout modern history, smallpox has held the top spot in killing human beings.

　　Smallpox is also the first infectious disease eliminated by human beings.

　　When future generations are exploring what killed smallpox, the trekking about how human beings overcome diseases step by step has merged into the long river of human medical history.

　　It is necessary for us to wade into this river at any time, go back to the way we came and find hope for the future.

　　The pockmarked emperor and the milkmaid

　　It is mentioned in Huangdi Neijing that "poison" should be used to treat diseases, and the so-called "fight poison with poison". Traditional Chinese medicine began to use this method to deal with smallpox, which existed during the Tang and Song Dynasties. Doctors take out the serous fluid from the abscess of smallpox patients and implant it into the body of healthy people for prevention and treatment, which is called human pox vaccination.

　　During the Wanli and Apocalypse years of Ming Dynasty, various books about human pox appeared. By the Qing dynasty, the method of preventing smallpox by human pox vaccination was widely promoted. Kangxi, the "pockmarked-faced emperor" who had suffered from smallpox, set up a pox clinic under the Tai Hospital and recruited famous doctors. Also in Beijing, a special "acne check chapter Beijing" is set up to take charge of the Eight Banners’ acne prevention. He specially sent people to welcome Ayla Zhang, a well-known folk vaccinia doctor, into the palace to vaccinate the royal family and banners.

　　Jared diamond, an evolutionary biologist and anthropologist, once revealed how the human body can defeat the virus: in the process of resisting a certain pathogen that infects the human body, the human body will gradually form specific antibodies, which makes it unlikely to be infected by the same pathogen again after recovery.

　　In the thousands of years of confrontation between human beings and smallpox, the latter has occupied an absolute advantage for a long time, and "pockmarked face" is so common that people without pockmarked face become special.

　　The 18th century was the age when smallpox ravaged Europe, and the British doctor edward Cenna (1749-1829) devoted himself to studying the solution. He noticed that almost all the female milkmaids had no "pockmarked faces". The beautiful milkmaid aroused Qinna’s curiosity, and he found one thing in common with them — — Cowpox of a milkmaid.

　　Vaccinia is a virus that can be co-infected by humans and animals, but it does no serious harm to cattle and people. There is a saying in the English countryside that "as long as you have suffered from vaccinia, you will not get smallpox".

　　Since 1788, Qinna began to carry out experiments on animals, using vaccinia of dairy women instead of smallpox patients to fight smallpox. For 8 years in a row, the experiment pointed to the same result, and vaccinia can effectively prevent smallpox.

　　On May 14th, 1796, Qinna conducted the first human experiment. He took the serous fluid Sarah Nelmes, a milkmaid, and inoculated it on the arm of phipps, an 8-year-old boy. Two months later, he inoculated phipps with real smallpox slurry. As a result, the boy was not infected with smallpox, and the previous vaccination seemed to have made him immune.

　　In the following two years, Qinna conducted the same human experiment many times, and the results were the same: all children who had had vaccinia were immune to smallpox virus. In 1798, Chennault announced that smallpox could be prevented by vaccination.

　　Vaccinium vaccination spread rapidly around the world. In 1977, Ethiopia recorded the last case of smallpox in human history. On October 26, 1979, WHO officially publicized that smallpox was eradicated all over the world.

　　This is the first time in human history to win the battle against infectious diseases.

　　Fatal bacteria and life-saving bacteria

　　Although the practical application of vaccinia technology is very successful, scientists are not satisfied. People need to explain theoretically why vaccinia can fight smallpox.

　　In the 1950s, chemist Louis Pasteur confirmed the relationship between diseases and germs, and found that specific microbial pathogens could cause specific diseases. Moreover, he found that the long-term growth toxicity of bacteria on artificial culture medium would be weakened, but the immunogenicity still existed.

　　According to this theory, in 1881, Pasteur artificially attenuated Bacillus anthracis with strong immunogenicity and inoculated it into sheep, which finally proved that sheep inoculated with Bacillus anthracis vaccine would not get the disease again.

　　Rabies virus can not be isolated and cultured like bacteria, but Pasteur confirmed that the pathogenic microorganism causing rabies exists in the spinal cord or brain tissue of sick animals. Therefore, he chose rabbit brain for subculture to obtain attenuated strains, and then successfully made live vaccines.

　　With the development of microbiology and immunology, vaccine is really defined as active immunity preparation for preventing infectious diseases, which is made of pathogenic microorganisms (such as bacteria, rickettsia, viruses, etc.) and their metabolites by artificial attenuation, inactivation or genetic engineering.

　　Based on this method, more vaccines can appear. Attenuated live vaccine made by heating inactivation of Vibrio cholerae; After 13 years and 213 generations of continuous culture on the culture medium, attenuated BCG was obtained.

　　With the development of the discipline, some traditional classical vaccine varieties have been further transformed into new vaccines, and some vaccines that cannot be developed with classical technology have found ways to solve the problem.

　　In 1972, recombinant genetic engineering contributed a lot of technical support and gave birth to recombinant gene vaccine. By using DNA recombinant biotechnology, natural or synthetic genetic material which can induce immune response in protein of pathogen shell can be directionally inserted into bacteria, yeast or mammalian cells, and the vaccine can be made after expression and purification. Nowadays, BCG, recombination vaccines, SARS vaccine, HIV vaccine and highly pathogenic avian influenza vaccine are being studied.

　　Conjugate vaccine appeared in 1980s. Scientists linked sugar molecules with protein (toxoid of Clostridium tetanus or diphtheria) by chemical methods, and developed a conjugate vaccine. Vaccines against pneumonia and meningitis are made in this way.

　　Looking at the present, the vaccine that has attracted much attention is none other than nucleic acid vaccine. Nucleic acid vaccine, also known as gene vaccine or DNA vaccine, transports DNA vaccine to human cells through some carrier (such as nanoparticles), which will guide the cells to produce immune active components, and then the cells will "spit out" these active components to stimulate the human body to obtain corresponding immunity, but it will not cause disease.

　　Nucleic acid vaccine can even transfect food cells, such as inserting hepatitis B virus nucleic acid vaccine into the genome of tomato cells, and inoculating the vaccine when eating tomatoes.

　　Scientific and technological progress brings infinite possibilities, and the new exploration of vaccination methods is also the tireless pursuit of scientists. In addition to traditional injection methods, oral administration, skin patch, nasal spray and improved fruit are all targets.

　　A never-ending struggle

　　With the development of immunology research, people have more and more expectations for vaccines, hoping that they will not only "prevent diseases". Researchers are already in action, trying to achieve the effect of treating diseases or preventing diseases from worsening by inducing specific immune responses. Such vaccine products are therapeutic vaccines.

　　There are many therapeutic vaccines that have been studied all over the world: tumor vaccines used for tumor treatment use tumor antigens for active immunization to stimulate the body’s active specific immune response to tumors to prevent the growth, spread and metastasis of tumors; Vaccines used for the treatment of cardiovascular diseases aim at intervening the immune process to prevent the occurrence and development of atherosclerosis (AS). A Swiss biotechnology company said that CYT006-AngQb, a vaccine used to treat hypertension, has a good clinical development prospect … …

　　On the other hand, when human beings are struggling to move forward, the "perpetrators" of infectious diseases are not willing to be silent. Since 1970s, more than 40 infectious diseases have been discovered in the world, such as HIV virus, avian influenza virus, SARS virus, mad cow disease prion, monkeypox virus, Lyme virus, Ebola virus, Legionella, Vibrio cholerae O139 and so on. People’s common influenza viruses are constantly innovating. For example, after the "Spanish flu" caused by H1N1 virus, the "Asian flu" and the "Hong Kong flu" were staged by H3N2 subtype virus. Or a lower-grade flu, it is staged almost every few years in Europe, America and Asia. There are also new viruses that have never met each other, eyeing and hiding in the dark.

　　"The only competitor competing with humans for the dominance of the earth is the virus." The words of lederberg, the winner of the Nobel Prize in Physiology or Medicine in 1958, sounded like an alarm bell. In the past two hundred years, the confrontation between human beings and germs was the fiercest. For the first time, we turned the tables, stood in a pre-emptive position, and seized the throat of the biggest killer of human beings. Compared with the end of the 19th century, the average life expectancy of human beings has been extended for several decades.

　　We have opened the "box" of vaccines. Overcoming the challenge of disease again and again makes us believe that disease creates problems and also provides understanding.

Implementing the innovation-driven development strategy and promoting "mass entrepreneurship and innovation" is a major deployment made by the CPC Central Committee. As for starting a business, we have heard the story that some entrepreneurs often raise millions of dollars and get rich overnight. Is it really that easy to start a business? It is also said that the success rate of starting a business is less than 1%, and a startup enterprise may face death if it is not careful. Is entrepreneurship really that terrible? The series report "Entrepreneurship on the Road" tells the ups and downs of these young people’s entrepreneurial stories.

Past lives, who knows Sichuan cuisine, tastes the private cuisine of Sichuan cuisine masters, and experiences the leisure of rural life … A new landmark of online celebrity, Sichuan Life Aesthetics Museum, was born in China Sichuan Cuisine Industry City, the first industrial functional area named after local cuisines in China, and now there are an endless stream of visitors here every day.

The poetic and atmospheric Sichuan Life Aesthetics Museum is only a part of the first opening area of Sichuan cuisine town. This project with a total investment of more than 20 billion yuan will bring surging new kinetic energy to the development of China Sichuan cuisine industrial city. Why should China Sichuan Cuisine Industry City, which mainly produces Sichuan condiments and snack foods, lay out a Sichuan cuisine town project with an area of over 1,000 mu?

Zhao Dong, head of China Sichuan Cuisine Industry City Management Committee, said in an interview that the eighth meeting of Chengdu Industrial Functional Zone and Park Construction Leading Group held at the beginning of this month made it clear that the name of Chengdu Sichuan Cuisine Industry Park was optimized and adjusted to China Sichuan Cuisine Industry City, which gave the functional zone a new mission from "garden" to "city". Sichuan Cuisine Town, a project with composite functions, can just fill the gap in the lack of high-end industrial communities in traditional industrial parks, provide high-quality living space for senior talents in Sichuan Cuisine Industry and undertake the task of Sichuan Cuisine Industry City.

Get through the pain point

Leading enterprises have expanded their production scale.

Machines are roaring, scaffolding is everywhere, and workers are busy … Walking into China Sichuan Food Industry City, which is located in Ande Street, Pidu District, "Building a new factory and expanding production scale" is the most frequently heard words by reporters. The construction of new production bases of a number of leading enterprises such as Dandan, Tianwei and Dingdianer is in full swing.

"Last year, we rose against the trend and achieved an operating income of 1.393 billion yuan, a year-on-year increase of 69.89%." Last Friday, the reporter came to the management committee of China Sichuan Cuisine Industry City, where an intelligent factory training was being held. Dai Li, the administrative director of Tianwei Food, listened very carefully. She wrote down a few pages in her notebook. "At the right time, the key word of our second phase project is intelligence. The workshop covers an area of 30 mu, and there are no more than 80 workers in a single shift. The annual output value created will be the sum of the four workshops of the first phase project ABCD, compared with the first phase, which covers an area of 120 mu.

Coincidentally, as the earliest project in the park, the second phase of Dandan Douban Project will be completed and put into production in June this year. The project will have an annual output of 60,000 tons of Pixian watercress and fine Sichuan composite condiment, and the same intelligent factory will be used. "In China Sichuan Food Industry City, intelligent production has become a trend." Yang Wei, personnel and administrative manager of Dandan Pixian Douban Group, said that the vast space for the development of Sichuan condiment industry and the good service of the Sichuan Industrial City Management Committee have made enterprises full of confidence in the future development.

Last year, the municipal and district governments gave a number of service packages to many enterprises in the industrial city. Take Dandan Douban as an example, it has enjoyed more than 4 million yuan of policy support funds such as online training and employee on-the-job training, and also enjoyed more than 4 million yuan of social security relief.

"Especially in the key links of the industrial chain, the Sichuan Industrial City Management Committee and various departments in Pidu District have made great efforts to find out the pain points and protect the development and growth of the enterprise." Du Jinchuan, director of the laboratory of Dandan Douban Quality Control Department, said that taking Shenzhen Yingbai Testing Technology Co., Ltd., which was introduced and settled by Pidu New Science Bureau, as an example, the company dispatched experts from Beijing, Shanghai, Shenzhen and other places to stay in Sichuan Food Industry City and set up Yingbai Testing Chengdu Laboratory, so that many enterprises can enjoy professional testing services without leaving the industry city.

"A variety of testing items were sent to Longquanyi for testing before, and we had to wait in line for a week or two. After the first phase of Chengdu Yingbai testing with an investment of 25 million yuan was put into use in December last year, we no longer had to go back and forth." Du Jinchuan said that now it can be said that you can enjoy the "VIP service", and the testing time has been shortened from one or two weeks to one or two days. If there is any problem, you can communicate at any time on the phone and WeChat, and you can also deal with it in time in case of an accident.

Not only inspection and testing, but also through the mode of "Commissioner+Expert", the Management Committee of Sichuan Industrial City has built a normalized and accurate docking platform between enterprises and famous food colleges such as Jiangnan University to promote the flow and aggregation of innovative resources to industrial functional areas and solve the "stuck neck" problem of industrial development.

Layout innovation chain

Aiming at the common bottleneck of industry and strengthening technical cooperation

"From Chengdu Sichuan Cuisine Industrial Park to China Sichuan Cuisine Industrial City, from’ Garden’ to’ City’, the functional area has been endowed with new missions and higher requirements, which need a new height and a new perspective to understand and grasp." In Zhao Dong’s view, this contains changes in concept, function, connotation and energy level. "As an important carrier of industrial agglomeration, functional areas should not only give full play to their advantages to be the’ long board’ of long-term manufacturing functions, but also fill the’ short board’ of urban service functions, create more complex and comprehensive regional functions, update and improve more sophisticated and diversified industrial service packages, and devote themselves to forming’ three lives’ of life, ecology and production.

The town of Sichuan cuisine is a representative project with many complex functions. Taking "two axes, six hearts and six districts" as the overall planning, the project uses innovative means, integrates international resources, promotes the upgrading of the three industries, improves the two industries and promotes the upgrading of one industry, and builds an ideal living town in Sichuan and Sichuan, China, which integrates "cultural tourism, pastoral, leisure, health care, education, suitability for business and livability" around the two IP’s of "Sichuan cuisine culture" and "modern urban pastoral". "Peng Xuqing, a master of Sichuan cuisine who has more than 7.3 million fans in Tik Tok, has now settled in the Sichuan Life Aesthetics Museum. Our guests have tasted the’ master dishes’ made by him and are full of praise." The heads of several enterprises in Sichuan Cuisine Industrial City said with emotion that from "people who produce in the city" to "people who produce in the city", the Andeyuan District People’s Hospital, the comprehensive convenience center and the foreign language school, which have been upgraded to a third-class hospital, have settled in one after another, and the supporting facilities of the industrial city are becoming more and more perfect, and employees can meet the needs of production and life without leaving the functional area.

"Not only the’ Master Cuisine’, but also Shuxiang 183, which will be unveiled in the next step, is another core competitiveness of us. The most authentic and representative foods from 183 districts and counties in Sichuan will be presented here, and they will be eaten all over Sichuan in one day." The relevant person in charge of Sichuan cuisine town told the reporter that the Sichuan cuisine town project is dedicated to building a Sichuan cuisine exchange and promotion center and a Sichuan cuisine experience tourism destination with the theme of excavating Sichuan cuisine culture and new consumption scenes. According to calculations, it will attract 4 million tourists every year in the mature period. Come here to experience consumption.

The introduction of huge traffic will also promote the transformation and upgrading of Sichuan cuisine industry. Sichuan Town will also plan to build 221 mu of high-quality science and technology space of "Sichuan Cuisine Kechuangli", focusing on the layout of "one headquarters and three centers" (science and technology research and development headquarters, promotion and operation center, incubation and transformation center, comprehensive service center), introducing R&D design, innovation and transformation, scene creation, community service and other functions, integrating related scientific and technological resources, building innovative platforms such as Sichuan Cuisine Industry Research Institute and Sichuan University, and accelerating the digital and intelligent transformation of enterprises in the park.

"We also set up a Sichuan food industry fund with a total scale of 1 billion yuan, focusing on Sichuan seasonings, including Pixian watercress and Sichuan compound seasoning. Next, we will actively pay attention to the new track of food and beverage such as central kitchen and tea, and make forward-looking efforts to broaden the categories. " Zhao Dong revealed that Pidu District will lay out innovation chain around the industrial chain of Sichuan cuisine, aiming at the common bottlenecks of the industry to strengthen technical cooperation. At present, Sichuan Cuisine Industry City has established a shared platform such as Sichuan Cuisine Industry Research Institute, Sichuan Cuisine Industry Park Innovation Center and condiment inspection and testing center. In the next step, it will tackle more than 30 research projects such as automatic circulating water replenishment in fermentation tanks, tank fermentation technology and Sichuan Cuisine processed dishes, so as to enhance the transformation capacity of Industry-University-Research.

　　Store grain in the ground, and store grain in technology. Today, agriculture is becoming a promising industry, and farmers are becoming attractive occupations.

　　The autumn wind bursts, setting off layers of rice waves and bringing the fragrance of rice. Approaching the edge of the field, waist-high rice is neatly spread out and extends to the foot of the distant mountain. In the rice field, several harvesters are running at full power and the roar is endless. On the ridge of the field, farmers hold mobile phones to check the growth of rice and the progress of harvesting, and their faces are filled with the joy of harvest. When I came to the 68th regiment of Kekedala City, the fourth division of Xinjiang Production and Construction Corps, a picture of autumn harvest in full swing came to my eyes.

　　The 68th regiment is located in Ili Valley, with fertile soil and abundant irrigation water. Thanks to superior natural conditions, the local area began to explore the cultivation of rice very early. However, due to the lack of advanced planting concepts and technical support, farmers have been exploring for a long time. The variety of rice in the field is mixed, and the height of rice seedlings is uneven, which is not only difficult to manage and protect, but also inefficient. Both the practical needs of increasing farmers’ income and the long-term overall situation of comprehensively promoting rural revitalization have put forward new and higher requirements for improving production technology.

　　Store grain in the ground, and store grain in technology. With the help of modern production technology, local rice planting has embarked on the road of intelligent production. The intelligent agricultural system has made the days of "steaming the summer heat and rusting the country, burning the sun on the back" gone forever. With the help of modern information technology, every field and every seedling has been monitored all the time, and the information such as soil humidity, pH value and rice seedling growth can be seen at a glance. Through the big screen of smart agriculture, technicians can analyze the situation of water and fertilizer, pests and diseases according to the data fed back by remote sensing. Under the precise guidance of data, intensive cultivation, accurate fertilization and reasonable irrigation have replaced extensive management, and watering and fertilization can be completed by machinery without leaving home. From "looking up to heaven for dinner" to "looking up to heaven for management", the unique natural endowment of Yili River Valley is being transformed into the development advantage of rural revitalization.

　　In the process of technology application, we are also faced with a task of coordinating agricultural production with environmental protection. For example, in Bole City, Xinjiang, in the past, planting corn had to go through fixed processes such as plowing and film mulching. When the wind blows over the newly turned land, it will raise dust all over the sky, and the broken plastic film will remain in the ground, which will not only be difficult to decompose, but also cause soil hardening. With the improvement of agricultural technology, farmers began to experiment with corn protective no-tillage technology. Not clearing the straw and plowing the land before cultivation not only reduces the loss caused by land ploughing, but also eliminates the use of plastic film, which not only saves a lot of costs, but also reduces land pollution and protects farmland and surrounding agricultural environment. Crops and land have achieved a virtuous cycle of planting in the middle and planting in the middle.

　　The introduction of advanced agricultural technology has enabled farmers to see the broad prospects of agricultural development and stimulated the enthusiasm, initiative and creativity of production. At first, the popularization of corn conservation no-tillage technology was not smooth. A farmer planted 100 mu with the mentality of giving it a try. When harvesting, he found out that "the yield per mu is more than 100 kilograms, and the cost has dropped, and the 200 yuan per mu is at least increased", and finally he decided to adopt protective no-tillage technology. Since the beginning of this year, the local promotion area has exceeded 30,000 mu. At harvest time, looking at the full corn in the field, the local people smiled.

　　From the foot of Tianshan Mountain to the Ili River, from desert oasis to vast grassland … … In more places in Xinjiang, agriculture has caught the express train of technological progress, production has become more and more convenient, and people’s lives have become more and more affluent. Today, agriculture is becoming a promising industry, and farmers are becoming attractive occupations. Better application of science and technology, agricultural science and technology to help rural revitalization, the pace towards agricultural and rural modernization will be more stable, and beautiful countryside, with strong agriculture, beautiful countryside and rich farmers, will gradually approach.

　　On the afternoon of April 10th, General Secretary of the Supreme Leader visited Yazhouwan Seed Laboratory and Sanya Ocean Research Institute of China Ocean University successively in Sanya, Hainan Province, to learn about Hainan’s support for seed industry innovation and the development of marine science and technology.

　　Standing at a new historical starting point, "China’s economic and social development and improvement of people’s livelihood need scientific and technological solutions more than ever before, and it is even more necessary to enhance the first driving force of innovation."

　　Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has visited the frontier of scientific and technological innovation for many times, and expounded the great strategic significance of scientific and technological innovation with vivid metaphors for many times.

　　"This ‘ Gold pole ’ I understand it as agricultural modernization. "

　　General Secretary of the Supreme Leader once told such a story. At that time, he was hungry and asked the people around him, what kind of life do you think is the best, and what are the specific goals? Try harder and think boldly about what is higher. "Their answer is — — I will carry a gold pole when I go up the mountain to work in the future! " "This ‘ Gold pole ’ I understand it as agricultural modernization. " The words of the Supreme Leader’s General Secretary contain true feelings.

　　"To solve the problem of eating, the fundamental way out lies in technology." The "golden pole" bears the farmers’ "money bag" at one end and the people’s "rice bag" and "vegetable basket" at the other. Agricultural modernization is based on seeds. "A seed can change a world, and a technology can create a miracle." The General Secretary of the Supreme Leader pointed out that we should make up our minds to develop the national seed industry, pay close attention to cultivating excellent varieties with independent intellectual property rights, and ensure national food security from the source. During this inspection in Hainan, the General Secretary made a special trip to Yazhouwan Seed Laboratory. Yazhouwan Seed Laboratory, established in May 2021, as a public scientific research platform built by Sanya Yazhouwan Science and Technology City, relies on and serves the national Nanfan Scientific and Research Breeding Base, and is guided by seed innovation and seed industry development, helping the high-quality innovation and development of seed industry in China.

　　General Secretary of the Supreme Leader profoundly pointed out, "Only by combining scientific and technological achievements with national needs, people’s requirements and market demand and completing the triple jump from scientific research, experimental development and popularization and application can we truly realize innovation value and realize innovation-driven development."

　　At the symposium of scientists in September 2020, the general secretary pointed out that "accelerating scientific and technological innovation is the need to realize people’s high-quality life" and "in order to meet people’s yearning for a better life, more scientific and technological innovations involving people’s livelihood must be introduced". It is on this occasion that the general secretary put forward new requirements for the vast number of scientists and scientific and technological workers to "face people’s lives and health." During the "Thirteenth Five-Year Plan" period, China has made a number of major scientific and technological achievements in the field of people’s livelihood science and technology. Integrated whole-body positron emission/magnetic resonance imaging equipment, rice breeding accelerators in unmanned plant factories and other scientific and technological innovations for people’s lives and health have been continuously unveiled and applied to a better life.

　　"Scientific and technological innovation, like a lever to incite the earth, can always create unexpected miracles."

　　In June, 2014, at the 17th Academician Conference of China Academy of Sciences and the 12th Academician Conference of China Academy of Engineering, General Secretary of the Supreme Leader pointed out: "Scientific and technological innovation, like a lever to shake the earth, can always create unexpected miracles. The development of contemporary science and technology fully proves this process. "

　　Scientific and technological innovation makes the deep sea no longer mysterious. In April, 2018, General Secretary of the Supreme Leader visited the Institute of Deep Sea Science and Engineering of China Academy of Sciences in Sanya, Hainan, to learn about China’s first 10,000-meter seabed exploration in the Mariana Trench, and went into the exhibition area of deep-sea exploration equipment with great interest to see all kinds of deep-sea diving high-tech equipment.

　　Technological innovation makes space no longer far away. Just last month, the second class of "Tiangong Classroom" was held in China Space Station, and the astronauts of Shenzhou XIII gave another wonderful space science class. During more than 170 days of space flight, three astronauts, with the support of ground technicians, carried out a number of scientific and technological experiments and application projects, setting many "firsts" and "firsts".

　　Scientific and technological innovation is the strategic support to improve social productivity and comprehensive national strength. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has made a major strategic choice of "innovation must be the first driving force for development" and implemented the innovation-driven development strategy.

　　"Life Gate", "Bull’s Nose", "Heaviest Weapon of the Country", "Fixed Sea Needle" and "Unique Weapon" … … Nowadays, China has started a new journey of building a socialist modern country in an all-round way, and the position of scientific and technological innovation in the overall development of the party and the country is more prominent.

　　"Innovative achievements should benefit the whole world, and should not become treasures buried in caves."

　　In November 2019, when the Chairman of the Supreme Leader met with foreign representatives attending the 2019 Innovation Economic Forum, he pointed out that "no country can become an independent innovation center or enjoy innovation results exclusively. Innovations should benefit the whole world and should not be a treasure buried in a cave. "

　　Fungus and grass technology, which has been popularized in more than 100 countries around the world, is a dazzling treasure out of the cave. With the long-term concern of the Supreme Leader, the fungus-grass technology of "replacing wood with grass" has gone out of China from Fujian to the world, which has played an important role in promoting local development and people’s well-being, and has been widely welcomed by developing countries.

　　"China is willing to work with all parties concerned to continue to contribute China’s wisdom and China’s plan for the implementation of the UN’s 2030 Agenda for Sustainable Development, so as to make mushroom technology benefit the people of developing countries ‘ Happy grass ’ ！” In September last year, the Chairman of the Supreme Leader pointed out in his congratulatory letter to the 20th anniversary of foreign aid to fungi and grasses and the International Cooperation Forum for Sustainable Development.

　　The world today is experiencing a great change that has never happened in a hundred years, and the domestic and international environment facing China’s development has undergone profound and complex changes. In the face of fierce international competition and against the background of rising unilateralism and protectionism, General Secretary of the Supreme Leader is far-sighted: "Scientific and technological achievements should benefit all mankind, and should not be a means to restrict or contain the development of other countries."

　　China’s scientific and technological innovation, not alone, nor narcissistic. "Promoting sustainable development through scientific and technological innovation has become the only way to solve some important global issues of concern to all countries." "We have expanded open cooperation in the field of science and technology, actively participated in solving major challenges facing mankind, and worked hard to promote scientific and technological innovations to benefit more countries and people." … … China’s scientific and technological innovation has conveyed China’s wisdom and contributed to China’s plan, which is promoting mutual benefit and sharing, unity and cooperation among all countries, creating a bright future together, and making continuous progress towards building a community of human destiny.
