Hiv immigrated to Taiwan Province Province.

Graduate students rely on original inventions and research to stand on their own feet in the forest of nations. China's national strength depends on your unremitting efforts. Now, they don't think of originality, but openly take the word "graduate student" and appear in Baidu's knowledge. Are you worthy of national training?

Such a simple question won't be? You're welcome to say, please forgive me!

Maybe time is short, I'll answer this time, but I hope I can forge ahead independently in the future! Learn for the rise of the Chinese nation! I posted this, too. You are under the composition!

In fact, the two problems are nothing more than three principles: the law of unity of opposites, the law of mutual change of quality and the law of negation of negation.

He Dayi, inventor of "cocktail therapy", reveals the secret of therapy.

He Dayi, director of the Allen Diamond AIDS Research Center in the United States, is famous for inventing the most effective cocktail therapy to prevent the onset of AIDS. Recently, he came to Shanghai at the invitation of Shanghai Disno Company. On a special occasion, the reporter had a dialogue with him.

Reporter: How does "cocktail therapy" work?

H: HIV is a difficult virus to deal with. It will constantly mutate, make mistakes every time it divides, and can't accurately copy genetic information, just like typing mistakes, and there is no error correction mechanism. Moreover, the replication speed is very fast, and hundreds of millions or even hundreds of billions of new individuals can be produced every day, and the speed is explosive. These characteristics can make the virus escape the attack of drugs.

If only one drug is used, the HIV virus can survive and even develop drug resistance with a slight change, which is the basic principle of cocktail therapy. "Cocktail therapy" is to use two nucleoside drugs and one non-nucleoside drug at the same time, so that HIV cannot escape.

Reporter: I heard that "cocktail therapy" will have more intense side effects?

Mr. Hu: Yes, some drugs can make patients have very realistic nightmares in the first few weeks, and many people are very afraid of it. Another side effect is called fat loss-the patient's face and arms will lose fat tissue. But if you stop taking the medicine, even if there is 0.00 1% virus left, the virus will come back.

Reporter: What are the consequences of improper medication?

Mr. Hu: The most direct consequence may be side effects. Because cocktail therapy is a mixture of many drugs, the size of side effects depends on what drugs the patient takes. Some drugs can cause gastrointestinal discomfort, while others can make people have nightmares. Some people are even allergic to certain drugs, which requires the supervision of experienced doctors.

Secondly, drug abuse will also make HIV resistant, and the consequence is that a certain therapy will fail, and patients will once again be at the point where there is no medicine available.

Reporter: In 20001year, Time magazine published a commentary saying that you "may be one of the few people who still believe that drugs can get rid of HIV", and some people doubt the effectiveness of drugs in treating AIDS. So, do you think cocktails can cure AIDS?

Ho: At present, "cocktail" can control HIV in patients, so that patients' immune system has a chance to repair and restore its function, but it can't clear or cure the disease.

Participating in AIDS research and treatment, people's emotions are like riding a roller coaster, with many intense ups and downs. Ironically, when I first chose this research project, I still believed that it could be cured with drugs. More than ten years have passed, during which I often feel helpless. To tell the truth, in the AIDS ward, the mood of doctors and patients is easy to fluctuate. But I will never give up my efforts and defeat this virus easily.

Then, he told the famous seaside story: an old man and a child were walking by the sea, and they found a batch of fish washed to the beach by the waves, and they were about to die of dehydration. The old man picked up the fish while walking and threw it back into the sea. The child asked, "You can't save all the fish." The old man said, "But the fish I threw back into the sea got help. This is all we can do. "

He Dayi, the inventor of "Cocktail Therapy" and a Chinese-American scientist, visited Shenzhen and was interviewed by our reporter.

An AIDS vaccine may be available in five years.

(Shenzhen Business Daily reporter Chen Guanglin) On July 4th, He Dayi, a Chinese-American scientist who invented cocktail therapy to treat AIDS, visited Shenzhen. During the first academic committee meeting of Chemical Genetics Laboratory of Shenzhen Graduate School of Peking University, Professor He Dayi was interviewed by our reporter.

The cost of cocktail therapy has been greatly reduced.

The interview with He Dayi started with a light topic. The reporter asked him if he was called "freshman". Any allusions? Professor He said with a smile that he had to ask his father. He also said humorously that his father was probably afraid that he didn't read much, so he called it "freshman" so that he could write well and recognize it. Professor He also said that this is his third visit to Shenzhen. Unfortunately, every time he comes and goes, he is in a hurry and has no time to visit this beautiful city.

At present, "cocktail therapy" is the most effective method to treat AIDS, but the cost is higher. In this regard, Professor He said that the cost of "cocktail therapy" has been greatly reduced. At first, the patient's annual treatment cost was $50,000. At present, the annual treatment cost of patients in Europe and America is only $6.5438+0 million, and it is even lower in Asia and Africa, which is about 654.38+0/654.38+00 of this figure. Of course, this figure is still high for many Asian and African countries, and AIDS patients in Asian and African countries are only people living in poverty. Therefore, they are still trying to continue to reduce costs.

Two anti-AIDS vaccines have entered the clinical stage.

As early as 2000, Professor He's key research on AIDS treatment has shifted to vaccine development. Regarding the progress of AIDS vaccine research and development, Professor He said that his team has developed two vaccines, both of which have entered the clinical stage. Among them, the clinical trial of DNA vaccine with nucleotide as the main body has been 65438 0.5 years, and the clinical trial of recombination vaccines with vaccinia virus as the carrier has been half a year. The test is in good condition now, but it will take at least five years to put it into use. He said: "AIDS prevention requires comprehensive measures. In the absence of specific drugs, developing preventive vaccines is an important part of the fight against AIDS. "

I hope people can understand AIDS correctly.

Statistics show that as of 2004, there were 38 million HIV carriers in the world. How to control the spread of AIDS and how to get along with AIDS patients? In this regard, Professor He hopes that the media will do more publicity. He said that many people don't understand HIV, and they are afraid and avoid AIDS patients. Actually, this is a misunderstanding. There are only three ways to spread HIV: first, through blood, second, through mother-to-child transmission, and third, through unclean sex. Others, such as sitting with patients, eating together, talking to patients, etc. Will not be infected, or even have a one-time relationship with HIV-infected people, and the probability of being infected is only 1% or even lower. Once the virus leaves the human body, it cannot survive, but can only survive and spread in the human body. He hopes that through media publicity, ordinary people will have a correct understanding of AIDS.

Research and development of AIDS vaccine began in 2000, and both vaccines have entered the clinical trial stage. At present, he is the director and professor of Allen Diamond AIDS Research Center of Rockefeller University in new york, USA, a member of the American Academy of Sciences and a foreign member of the China Academy of Engineering.

Another problem is mainly the "interconnectedness" of the network, that is, all things and cities are interconnected.
