Depp joined Hollow Man.

　 　 1905 movie network news Universal Picture’s "Monster Universe" plan is moving forward in an orderly way. A few days ago, the remake of Hollow Man attracted a famous actor to join us. It is reported that Johnny Depp will definitely join the film and play the role of invisible man in the film. In the original film, the invisible man became a killer after being invisible, and there were killers in Depp’s previous screen roles, so this role is more suitable for Depp to interpret.

　 　 The original Hollow Man, filmed in 1933, tells the story of a talented scientist who invented an invisibility reagent that can make people invisible after drinking. Although the effect of the reagent is obvious, unfortunately, the side effects make the scientist become eccentric, and gradually, he becomes an invisible killer. The film depicts the alienation of science and technology to human beings. Although it is exaggerated, the scenes of a large number of invisible people killing people in the film are still chilling. The film has been put on the screen five times. The famous David .S. Goyer once filmed a version in 2007.

The 1933 edition of Invisible Man

　 　 As early as last year, Universal decided to build a "monster universe", hoping to copy the successful experience and bring the famous monsters in the film history such as Dracula, Frankenstein, Frankenstein’s bride, werewolf, invisible man, mummy, and Black Lake Fishman to the big screen. Judging from the progress of the current exposure, the list signed by Universal is big: Tom Cruise just confirmed to join us not long ago, and now Hollow Man has invited Depp to join us. Just from the stunt, this "monster universe" can be described as huge.

　 　 Universal Picture’s Hollow Man will be written by ed solomon, a screenwriter, and the director candidate and release time have not been decided.

　　　　 On August 28th, Beijing time, according to foreign media reports, Conor McGregor, a mixed martial arts athlete, joined the action thriller "Veyron kill array" and made his debut, playing an original role other than himself.

　　The film, starring Jake Gyllenhaal, directed by doug liman and produced by Amazon, will be streamed online. Ji Runhall plays a former UFC fighter who works as a bodyguard in a disorganized hotel in the Florida keys, but soon discovers that everything is not what it seems in this tropical paradise.

　　Billy magnussen, Daniela Melchior, Jimsola Akumello, Lucas Gage, Anthony Bagarozzi (The Tear-Resistant Detective) and Chuck Mundre are also the screenwriters, and filming will begin in the Dominican Republic later this month.

　　In 1989, the original film was directed by Rowdy Herrington and starred by Patrick Swayze, kelly lynch, sam elliott and Ben Gazzara. Dalton, an outstanding and popular bodyguard, moved to a small town in Missouri to help clean up a disorderly bar, exposing the corrupt behavior of local bully businessmen in the process.

On May 17th, during the 2022 World Telecommunication and Information Society Day Conference, China Unicom successfully held the launch conference of innovative achievements of 5G application sailing, and jointly released the 5G private network PLUS scene products "5G accompanying private network" and "5G multi-park private network" with industrial partners, and held the unveiling ceremony of the OPENLAB open laboratory of 5G Internet of Things to promote the 5G application sailing.

Liang Baojun, deputy general manager of China Unicom, said in his speech that China Unicom has implemented the "Sailing Action Plan for 5G Applications (2021-2023)" of ten departments including the Ministry of Industry and Information Technology, focusing on the five main businesses of "big connection, big computing, big data, big application and big security", focusing on "building the cornerstone of 5G computing network, promoting 5G wisdom and gathering 5G ecological partners". 1,500 5G industry virtual private network projects and 5,000 5G commercial industry application projects, covering more than 20 sub-sectors such as steel, mining, education, cultural tourism and medical care, and accelerating the 5G integration innovation from pilot demonstration to scale replication.

Take advantage of the situation and gain insight into the "new track" of industrial digital transformation

Wang Zhiqin, vice president of China Information and Communication Research Institute, pointed out in his speech that the new digital infrastructure represented by 5G is driving the continuous upgrading of production methods, lifestyles and service systems, and promoting the continuous deepening of digital transformation in various fields of economy and society. As a new industry information infrastructure, the virtual private network of 5G industry has evolved from 1.0 to 2.0, realizing the evolution of 5G from ToB general network to customized network of thousands of industries. China Unicom has continuously deepened the private network market and continuously introduced innovative products of 5G private network PLUS scenes, which has achieved fruitful results in the digital transformation of 5G empowerment industry.

In order to continuously accelerate the transformation of 5G applications from "model rooms" to "commercial houses", Wang Zhiqin proposed that the first is to formulate a series of standards for 5G industry private networks and build a cross-border integration landing system; The second is to build a cross-border communication platform and build an application ecological cultivation system for the 5G industry; The third is to establish a "model room" for the application of the 5G industry and establish a publicity and promotion system.

Ingenuity forging, gaining momentum to innovate and develop "new kinetic energy"

The 5G private network has become a "new engine" for the technical integration of 5G vertical industries and communication fields and the high-quality development of 5G applications. At this conference, China Unicom, together with ICT Institute, State Grid Shandong Electric Power Company, Guangdong Bureau of Politics and Statistics, FAW Group, Beijing University of Posts and Telecommunications, Huawei and other industrial partners, released the 5G private network PLUS scene products "5G accompanying private network" and "5G multi-park private network".

Concentrate on the strength and win-win situation. 5G application sails the value of "new blue ocean"

Walking alone is fast, and many people travel far. At this conference, China Unicom, together with partners such as ICT Institute, State Grid Shandong Electric Power Company, Huawei and Zhuhai Gree, jointly released the OPENLAB of the 5G Internet of Things, built a joint innovation technology service platform, and accelerated the consolidation of the application technology foundation of the 5G industry.

5G pilot, sail the future. China Unicom is willing to join hands with all parties in the industry to promote the integration of 5G into thousands of industries and create a new blue ocean of digital economy.

It’ s too embarrassing … Although I knew in advance that BYD was going to engage in intelligent driving of the whole car, I really didn’ t expect that it was close to the standard of the whole department. (PS: products under 100,000, this is the second time to start carrying)

Eye of the God 100-Blue Tail Mark-High Speed Pilot

Eye of God 300-Red Tail-City without Map

See for yourself the specific car payment. Careful students have already seen it. Not this time, it should not be, and it is not a succession relationship with up. Students with insider can comment on it, and then I will ask BYD’s classmates and give you an answer.

The growth rate of China market is higher than that of the whole world.

From 2010 to 2020, the market size of China’s pet industry increased from 13.44 billion yuan to 72.73 billion yuan, with a compound annual growth rate of nearly 20%, which is higher than that of the whole world. In 2020, the US pet consumption market accounts for 41.1% of the world, ranking first, and China accounts for 8.1%. The pet raising rate and the annual consumption of a single pet in China are far below the level of developed countries, and there is much room for growth in the future.

Judging from the proportion of pet expenditure in household consumption, in 2014, the difference in the proportion of pet expenditure in household consumption between China and the United States was 3.1 times, and in 2019, the difference dropped to 1.8 times.

1. The average annual compound growth rate of China’s pet industry is nearly 20%, accounting for less than 10% of the global market.

With the development and prosperity of China society, the role of pets is gradually changing — — Cats and dogs are increasingly regarded as indispensable members of the family, rather than simply companion pets. Social media has also promoted pets to become an important part of young people’s lives, and the trend of "raising cats in the cloud" has made owning pets more desirable. Therefore, the pet market has grown rapidly in the past 10 years. In 2020, the pet consumption market in China will be 72.73 billion yuan, up 21.1% year-on-year, and the CAGR will be 18.4% in 10 years.

With the development of economy, the consumption of pets is also increasing. Families in most developed countries regard pets as family members, and the spending on pets is increasing. According to Euromonitor data, in 2020, the global pet market industry scale will be about US$ 138.2 billion, up by 4.4% year-on-year, and the CAGR will be 3.6% in 10 years. Among them, the pet consumption market in China, Japan and the United States accounted for 8.1%, 4.2% and 41.1% of the global market respectively.

2. There is a big gap between China’s pet raising rate and single pet consumption amount and developed countries, and there is huge room for improvement.

In the past decade, the changing population and social structure, as well as the improvement of income and adoption rate, have become the main factors to promote the growth of pet keeping rate in China. Compared with other parts of the world, in 2019, the family pet raising rate in China was only about 17%, far lower than 67% in the United States, 62% in Australia and 44% in the United Kingdom. The pet raising rate in China is far lower than that in developed countries, and there may be several times room for improvement in the future.

Since 2016, the growth rate of China’s single pet consumption has increased year by year, mainly driven by the increase of per capita disposable income and the enhancement of pets’ kinship attributes; In 2020, the annual consumption of a single pet in China will be $59. Compared with other countries, in 2020, the consumption of single pet in Japan and the United States will be $317 and $343, respectively, and the consumption of single pet in China is still lower than that in developed countries.

3. The proportion of pet expenditure in household consumption in China has increased, and the gap with the United States has narrowed.

From 2014 to 2019, the proportion of pet expenditure in household consumption in China increased from 0.16% to 0.29%, and the proportion of pet expenditure in household consumption in the United States in 2019 was 0.52%. In 2014, the difference in the proportion of pet expenditure in household consumption between China and the United States was 3.1 times. In 2019, the difference dropped to 1.8 times.

It can be seen that there is an obvious trend of consumption upgrading in the pet market in China, which accelerates the expansion of the pet market. With the stronger willingness of consumers in China to invest in pets in the future, the pet industry has great development potential.

Recently, official website, the National Network Information Office, announced the third batch of problematic websites investigated and dealt with according to law in the 2020 "Clear Lang" special action and the special rectification activities of online class platforms. In addition to some live broadcast platforms, Baidu Post Bar is also impressively listed.

The reason why Baidu Post Bar was named this time: "LOLI Bar", "CQY Bar" and other post bars and accounts published pornographic information of underage "Welfare Ji", and sold pornographic selfies, videos and other resources of minors in the name of accompanying play and chatting.

In recent years, Baidu Post Bar has been paid attention to by the public every time, either because of rampant black production or because of malicious speculation, and there are few good things. At the end of September, a malicious phishing post "Brother, our family is rich" in Baidu Post Bar caused widespread discussion on the Internet because of the anxiety of selling bride price, which led a large number of angry netizens to rush into Baidu Post Bar, find the original post and accuse the landlord of being "selfish".

In the end, the incident took a surprising turn, and the posting party saw that the incident was getting worse and worse, so they had to admit that the post was fabricated and apologize to the public, but the poster also stressed that the post could not be deleted because of unknown reasons. The reason why this incident has become a hot topic is that someone has led the way and pointed out that the initiator is "Anti-stress Bar Team 1".

The reason why the incident successfully went out of the circle is unknown, but people can’t help but sigh that Baidu Post Bar, as one of the founders of the Internet community, has fallen to the point where it can only be remembered by maliciously fabricated public opinion events.

At that time, Baidu had money and resources. Even now, it is still a "skinny camel is bigger than a horse". However, Baidu Post Bar has gradually declined and lost its advantage in the community track.

The decline of Baidu Post Bar is not only attributed to the rise of competing products, but also to Baidu’s own strategic problems. Baidu’s attitude towards the light operation and light control of Post Bar makes the high-quality content of Post Bar languish day by day. Baidu Post Bar was born to improve the user’s stickiness, but Baidu seems to have forgotten for a long time that the loss of high-quality content pool will eventually lead to the shrinkage and collapse of the core business-search engine business.

From popularization to minority

Baidu Post Bar, launched in 2003, is a veteran Internet community. The idea of Post Bar came from Baidu CEO Robin Li. At that time, the search engine was considered as a "run-away" product, but Robin Li wanted to break this shackles, so he thought of making an interest community with keywords as the core, so Post Bar was born.

From the end of the 20th century to the first decade of the 21st century, online forums such as Maopu, Tianya and Post Bar jointly created a brilliant BBS era. However, the good times didn’t last long. After 2010, the barbaric growth of the mobile Internet created the rise of Weibo, and the old-fashioned communities that clung to the remnants suffered a huge impact, and Post Bar was no exception, and gradually declined.

The decline of communities such as Post Bar also lies in the high decentralization of these established communities. For example, each netizen’s post can be exposed relatively fairly according to the timeline. However, since its launch, Weibo has continuously highlighted the role of operation, taking the topic of stars and hot events as a gimmick to attract users to join. With the help of stars and hot topics, Weibo has become a new generation of Internet darling.

On the other hand, in the face of the rise of Weibo, Post Bar did not seek mutation, still stuck on its laurels, did not iterate frequently, and never made a big breakthrough in function and operation. A few years later, Zhihu rose. Zhihu, which is problem-oriented, is equivalent to a dimensionality reduction blow to Post Bar, because people will not only search for words but also search for questions on the search engine side, so that when people search for a certain question in Baidu, the more relevant search results are often the questions in Zhihu.

Although Baidu also has its own Q&A product, Baidu knows that it can complement the Post Bar in content, but it is still broken by Zhihu. Zhihu and Weibo are similar, with heavy operation and KOL as the core, so they successfully went out of the circle, further dividing the time and attention of netizens.

In early Zhihu, the invitation system was implemented, and there were many professionals and intellectual groups in various fields, and the atmosphere of seeking knowledge was strong, which laid the community tone of "knowledge first" in Zhihu. Therefore, a large number of outstanding creators were successfully precipitated, forming a differentiated competitive advantage with Baidu Know and Baidu Post Bar.

Post Bar and Baidu know that it is still a straggler, and there is no professional operation and integration of high-quality creator resources, which makes it difficult to form a high-quality content pool and thus it is difficult to retain high-quality users.

In June, 2016, something happened that dealt a further blow to Post Bar, that is, the launch of Weibo Chaohua. Before the introduction of Chaohua in Weibo, Post Bar has always been the main gathering place for fans. Fans can discuss stars in Post Bar, and even support activities can be organized through Post Bar.

Baidu Post Bar, which has a huge groupie user, has no star resources, but there are many stars in Weibo. After Weibo used his own star resources to launch Chaohua, Chaohua quickly became the core base for fans to discuss idols. As a result, a large number of fans have left the post bar.

What makes Baidu Post Bar even more embarrassing is that the bar service team, the core resource of Baidu Post Bar, is also moving closer to Weibo. For example, the most famous post bar "Li Yiba" (Diba) opened its official micro-blog in Weibo.

At present, Diba Guanwei has 1.17 million fans and has played a positive role in many sensitive events. Last August, Diba organized a massive "expedition" activity, which was highly praised by a number of official media. However, the traffic generated by the activities of Diba is not directed to the Post Bar, and it is still Weibo who enjoys the heat bonus.

At present, the hottest posts in Baidu Post Bar are mainly games, animation, digital and sports posts. Games and animation belong to the secondary subculture, while digital and sports are the favorite of straight men, and the diversity of users is relatively poor. Without the resources of stars and high-quality creators, groupies and high-quality users are constantly losing, and the audience of post bars is getting narrower and narrower, gradually sliding from the public to the minority.

Baidu’s mistake

The early post bar can become a phenomenal community product, and Baidu’s traffic blessing is very important. However, the decline of Post Bar is not only due to the rise of competitors, but also due to Baidu’s decision-making mistakes in products and strategies.

Li Yanhong’s continued contempt for the mobile Internet has led Baidu to miss the era of mobile Internet and lose its advantage in the mobile battlefield. When Baidu was aware of it, it had already given away its own traffic.

Baidu had many high-quality post bars in its early years, such as various post bars for postgraduate entrance examination and skill learning, which contained many dry goods and self-study tutorials. However, Baidu, which was weak on the mobile side, lost the favor of users, and people flocked to various learning classes in Weibo. There are also many young people who flock to bilibili to study. With the help of video, a more expressive medium, bilibili has a unique advantage in learning resources.

On the other hand, Baidu’s social strategy has always been to integrate social elements into core products, rather than developing a social product alone. Based on this idea, Baidu Post Bar failed to seize the opportunity of transformation and became a semi-community and semi-social product like Weibo.

In addition to the topic discussion, Baidu Post Bar has another identity, which is the "answer library" of Baidu search engine business. Because Baidu Post Bar is deeply bound to Baidu’s search engine, when users use Baidu to search for keywords, corresponding post bars will appear in the search results, and when users search for multiple keywords or sentences, posts with high relevance will appear in the search results.

Post Bar is born for interest, but for those who have no specific interest and just want to find the answer to the question in Post Bar, Post Bar is still a disposable product with poor user retention rate. However, the identity of "answer library" is not completely without benefits for Post Bar. For people who are not deeply exposed to the Internet, Post Bar located in the front row of Baidu search results is an important way for them to obtain information.

"Last spring, when I was Baidu’s mushroom farming skills, I found a post in the post bar to promote mushroom farming supplies, and the price was a little lower than the market price. Feng Yuqin is a mushroom farmer in the northeast rural area. She shared her experience of being cheated on Baidu Post Bar with "Internet insider". "Later, I added the post owner’s WeChat and bought more than 500 yuan of mushroom farming supplies through WeChat transfer. Later, the courier reminded me that the parcel was collected and the postage was more than 300 yuan. If you refuse, you won’t get your money back, because the seller has blacked out my WeChat, so you have to bite the bullet and pay the postage.

For Baidu Post Bar, there are not a few sinking market users like Feng Yuqin, who make it difficult to distinguish all kinds of information in the post bar. Over time, Baidu Post Bar has become a popular place for some unscrupulous traders.

There is no doubt that the UGC attribute of Post Bar is strong. If it is not re-operated and re-controlled, the community tonality will develop in an uncontrollable direction. Post Bar, however, is a product of Baidu’s "stocking". Post Bar is created by an individual application, and the bar staff has extremely high permission to post it. Baidu’s official operational role has been greatly weakened.

Baidu Post Bar’s official limited regulation of Post Bar has also been criticized as "three views are touching". In the emotional column of Baidu Post Bar, there is a classification of "beauty". Under this category, there are many post bars that cater to the preferences of diaosi groups, such as "black silk bar", "beautiful legs bar", "stunner bar", "connotation map bar" and "student girl bar", and these post bars are undoubtedly hotbeds for black production.

The recent exposure of "LOLI Bar", "CQY Bar" and other post bars selling underage "Welfare Ji" pornographic resources is the tip of the iceberg.

The prevalence of black products also shows that users of Post Bar have great value, but Baidu is "lazy" and has not explored a diversified profit model. For a long time, it has been realized by advertising, membership and selling Post Bar. At the beginning of 2016, the "hemophilia bar" was sold, which once caused Baidu to fall into a major public opinion crisis.

Due to the obvious community attribute, Post Bar is the most dynamic and advantageous product in Baidu’s own content pool, but now it has become Baidu’s "time bomb", and negative news will be exposed every one or two years, hurting Baidu’s vitality. It can be predicted that Baidu’s search business will become increasingly depressed if all kinds of ills of Post Bar are not removed.

Baidu urgently needs high-quality content pool.

As a search engine, Baidu’s nourishment includes its own content and external content, and building its own high-quality content pool is the key to enhance its competitiveness. Around the search engine, Baidu has developed a series of content products to expand Baidu’s content pool, including Baidu Post Bar, Baidu Know, Baidu Experience, Baidu Library, Baidu Encyclopedia and Baijiahao.

Baidu knows that the status quo of Baidu’s experience, like a post bar, has been largely replaced by Zhihu, a professional creator. After cracking down on piracy in China, Baidu’s library will no longer be brilliant. Baidu’s expectation of revitalizing high-quality content is pinned on Baijiahao, the benchmark WeChat WeChat official account.

However, the overall content quality of Baijiahao has been difficult to compete with WeChat WeChat official account. On the one hand, Baijiahao is different from WeChat WeChat official account’s "Hundred Flowers Bloom". Baijiahao is more inclined to recommend short information, and the long and in-depth content is not the main support object of Baijiahao, which hinders the development of high-quality content in Baijiahao to some extent; On the other hand, Baidu has a large user base and a high proportion of sinking users. Due to the influence of recommended algorithms, it is inevitable that low-quality content will prevail; Moreover, Baidu does not have a strong application ecology, which leads to the poor liquidity of Baijiahao, so few high-quality creators regard Baijiahao as the main position of content creation.

Baidu has not made efforts on specialized high-quality content, but this force target is Baidu Encyclopedia. Baidu Encyclopedia started the operation of high-quality content matrix around 2014, and derived content sections such as featured encyclopedia, second encyclopedia and V encyclopedia, and introduced authoritative creators in various fields to output high-quality content. However, the entrance of these high-quality content is deeply hidden and difficult to be found and used by users.

Encyclopedia of science under the classification of characteristic encyclopedias

Baidu’s planning mistakes in the high-quality content pool have caused the loss of users, the decline of word of mouth and the shrinking of core search business. StatCounter statistics show that in 2018, Baidu’s share in the domestic search engine market was 70.3%, and by 2019, this figure fell to 67.09%. The market share of sogou search and Shenma Search is rising steadily.

Sogou, backed by Tencent, launched the WeChat channel in 2014, which opened a huge pool of high-quality content, and launched the Zhihu channel in 2015, which means that sogou search has captured another city in the pool of high-quality content. Users who are increasingly eager for high-quality content are gradually migrating to sogou.

In addition to sogou, a strong rival, all mobile rivals are also eating into Baidu’s search business. The Shenma search created by UC and Ali has thrived under the protection of UC browser; Wechat and today’s headlines also started their own search business, feeding the growth of mobile search business with the application matrix of their own camp as nutrients.

Giants have built their own search businesses, and their confidence comes from their own layout in various content tracks. Wechat Search contains WeChat WeChat official account, video number, applet, Tencent video, WeChat reading, QQ music, JD.COM Mall and other channels, which is enough to support the basic disk of WeChat search; Headline search also integrates the resources of content products such as headline number, micro-headline, Tik Tok, headline question and answer, and has strong strength.

In contrast, Baidu’s content is short-lived. Baidu, which is centered on search engines, does not have a fist-level content product. When competitors are mainly based on their own content pools and supplemented by external content pools, Baidu products represented by Post Bar are gradually declining.

In the face of all kinds of big moves by competitors, such as holding a strong group or integrating the application matrix, if Baidu can’t make great progress in high-quality content, it will eventually lose the throne of the first search engine. If the search engine business loses its advantage, it will not be far from the total collapse of Baidu Empire.

At present, it is popular in novel coronavirus. At the same time, we also hear the news that there is no specific drug at present. Some people may ask: Why can’t we treat it with antibiotics?

Because the pathogen this time is a virus, not a bacterium!

What are the similarities and differences between viruses and bacteria? Why can’t we kill the virus with antibiotics?

Are tiny creatures on the earth.

Bacteria and viruses are microorganisms. As the smallest life form on the earth, people always ignore their existence, but this tiny creature is always painted with a sense of existence, and people will be infected by them if they are not careful.

Bacteria are cells, which have cell walls, DNA and organelles. They can produce and metabolize needed enzymes by themselves, and can divide and reproduce by themselves. Viruses are much smaller than bacteria, and the main structure is protein capsid and internal genetic material (DNA or RNA), and viruses cannot replicate themselves. Viruses need to replicate their genetic material by infecting host cells, and then release more offspring viruses to infect other host cells.

Bacteria can be harmless or even beneficial to human health, and can live independently. The purpose of the virus is to replicate itself, so it has no meaning unless it infects the host. It can be described as the purest "selfish gene".

The size difference between them is about 1000 times.

Bacteria in a broad sense are prokaryotes. Although they have a cell structure, they are still very different from human cells. Their structures are simpler, and they have no nucleus, but only a DNA aggregation area-pseudonucleus. Bacteria are generally spherical, rod-shaped, spiral, etc., and people do not forget to add a description of their shapes when naming them, such as Escherichia coli, Lactobacillus, Staphylococcus aureus and so on (ps. Yeast is a fungus, so there is no shape in the name.

At present, the smallest known bacteria are only 0.2 microns long, so they can only be seen under a microscope; The largest bacteria in the world can be directly seen by naked eyes, and it is 0.2-0.6 mm in size. It is a kind of bacteria called Sulphidophilus Namibia.

Bacterial size

Virus is a noncellular form composed of a nucleic acid molecule (DNA or RNA) and protein. It lives by parasitism and is an organic species between living things and nonliving things. After it enters the cell, its metabolism such as DNA replication is indeed the characteristic of living things, while after it leaves the cell, it is just a lifeless crystal.

Novel coronavirus electron micrograph 　

Most viruses are between 10 and 300 nanometers (nm) in diameter. Some filamentous viruses can be as long as 1400nm, but their width is only about 80nm. Most viruses cannot be observed under optical microscope, and scanning or transmission electron microscope is the main tool to observe the morphology of virus particles. Compared with bacteria, viruses differ in size by about 1000 times.

There are also different ways to invade the human body.

There are many "good people" in bacteria, among which saprophytic bacteria are important decomposers in the ecosystem, which makes the carbon cycle go smoothly; Some bacteria will carry out nitrogen fixation, so that nitrogen can be converted into forms that can be used by biology. The production of cheese, yogurt and fermented grains, the manufacture of some antibiotics and the treatment of wastewater are all related to bacteria. In the field of biotechnology, bacteria are also widely used. Of course, the "bad guys" in bacteria are many pathogenic bacteria, including tuberculosis, anthrax, plague and other diseases are caused by bacteria.

The relationship between bacteria and human body is mainly parasitic. Let’s mainly talk about pathogenic bacteria. Because most bacteria have their own metabolic system, bacteria can be parasitic between normal cells of human body after invading human body. Bacteria take away the nutrients necessary for the body; The growth of bacteria produces various metabolites, which disrupts the physiological balance of the body; Even the size of bacteria has become a pathogenic factor, which interferes with and destroys the function of cells. Therefore, in some diseases, the proliferation of bacteria alone has fatal consequences.

The virus may have invaded the human body from a sneeze or a physical contact. Viruses need to parasitize in living host cells, and rely on host cells to provide the raw material system, energy and place needed for virus replication. When a virus is ready to infect a host cell, it needs the following six steps to complete its proliferation activities, namely adsorption, invasion, hulling, biosynthesis, assembly and release.

Adsorption: The virus "targets" the target cell by recognizing the specific receptor protein molecules on the surface of the host cell membrane (for example, novel coronavirus virus recognizes angiotensin converting enzyme 2 -ACE2)； on the surface of human respiratory tract and lung cells); Invasion: then the virus either enters the host cell in some way (such as membrane fusion) or directly injects genetic material into the host cell; Shelling: Immediately after the viral infectious nucleic acid is released from the capsid; Biosynthesis: "non-stop" biosynthesis-synthesizing virus nucleic acid and protein according to gene instructions and with the help of raw materials, energy and places provided by host cells; Assembly: The newly synthesized virus nucleic acid and protein will be assembled into progeny virus; Release: the progeny virus is released outside the host cell.

Human body’s defense and counterattack

Both bacteria and viruses have to break through the human body’s defenses to complete the invasion, but the human body will eventually find their existence, and the human immune system has its own protective measures and early warning mechanism.

The first line of defense: skin and mucous membrane. The first way for human beings to protect themselves is defense, which makes the human body form a relatively closed system through the skin and mucosa. When harmful substances are about to invade the human body, the skin and mucosa will block the external pathogenic factors out of the body.

The second line of defense: bactericidal substances and phagocytes. There are always bactericidal substances and phagocytes patrolling the mucosal surface and inside the human body to prevent the invasion of pathogens. Take lysozyme as an example, it can destroy the cell wall of bacteria, cause the contents of the cell wall to escape and dissolve the bacteria, and can also directly combine with negatively charged virus proteins to form double salts with DNA, RNA and apoprotein, thus inactivating the virus. Therefore, the enzyme has antibacterial, anti-inflammatory and antiviral effects.

The third line of defense: specific immunity. When the powerful pathogen broke through the first two lines of defense, the human body’s counterattack just began. Through the phagocytosis of phagocytes and the analysis of special immune cells (T cells), the human body has produced antibodies that can specifically recognize invaders. The antibodies can make pathogens stick together and no longer be invasive, and finally the pathogens exposed between cells will be killed. But is the virus that invaded the cell safe? No! The human body can subtly identify which cells are infected by the virus, and then send a "killer" to kill the infected cells and release the virus inside the cells for antigen elimination.

However, it takes time for the human body to fight back, and pathogens will invade and occupy the human body through such a time gap!

Auxiliary appearance: drug therapy

Bacterial infection once became the greatest enemy of mankind. For example, the plague was called the "Black Death" in Europe, which reduced the population of Europe by one third in three years. At present, plague and cholera are classified as Class A infectious diseases in China. It was not until the discovery and popularization of antibiotics that human beings controlled the outbreak of bacterial infection.

Antibiotics mainly kill bacteria by destroying the structure of bacterial cells, such as cell wall, cell membrane, changing internal metabolism, hindering the synthesis of nucleic acid and protein, etc.

Chemical structural formula of penicillin

However, antibiotics are ineffective against viruses! Because bacteria and viruses have completely different structures!

Because bacteria have cell walls, as well as their own nucleic acid replication machines and ribosomes, antibiotics can kill bacteria with little side effects on humans as long as they are designed for these targets. However, the virus has no cell wall, its own nuclease and ribosome, and all its functions depend on the host cell. So antibiotics can’t kill viruses (we can’t make an "antibiotic" that kills host cells).

The ideal antiviral drugs can not only act on one or several links of the virus proliferation cycle, but also interfere or block it without affecting the normal metabolism of host cells. For example, ribavirin, a common drug, provides a large number of nucleotide analogues, which replace normal nucleotides, making the virus lose its replication ability and play a role in inhibiting virus amplification (but it also has great side effects on human body). In addition, the anti-influenza drug oseltamivir works by blocking the release of the offspring virus.

In view of this pneumonia epidemic, researchers from Wuhan Institute of Virology, China Academy of Sciences and Academy of Military Medical Sciences have also preliminarily screened out ramidivvir (GS-5734, phase II clinical anti-Ebola drug) and Chloroquine (Sigma-C6628, antimalarial drug) which have good inhibitory effects on novel coronavirus (2019-nCoV) at the cellular level.

But we have to say that in the face of virus treatment, human beings have never found a universal specific drug like antibiotics. Active treatment is to mobilize the human body’s own immune ability to fight against viruses, because only organisms themselves really know how to fight against organisms.

On February 11th, BYD announced at the Eye of the Gods Intelligent Driving Conference that in the next 2-3 years, intelligent driving will become the standard, and all BYD models will be equipped with the "Eye of the Gods" advanced intelligent driving system, and the first batch of 21 models will be listed soon.
