Chapter 139 Detecting New Methods
On March 3, Zhou Yu and Chen Jin accompanied Xiao Meiling and his wife to the Spark Science and Technology Research Center.

Chen Jin continued to comfort Xiao Meiling: "Sister Xiao, the Life Safety Research Institute led by Director Wang Xiaoxiao has developed a rapid HIV detection method.

HIV infection can be determined after one week of high-risk behaviors, compared with three months after conventional means.

If it is confirmed that Sister Xiao has been infected with AIDS, we can intervene immediately. If Sister Xiao is healthy, we can stop taking the blocker drugs in time. "

Zhou Yu led them into the Life Safety Research Institute.

The first feeling here is cleanliness, not the kind of spotless cleanliness, but the pursuit of sterility.

Zhou Yu pointed to the heavy glass door on the left, and introduced to everyone: "This is the biosafety level [-] laboratory built by our company. This laboratory can study all virulent viruses, and we don't have to worry about viruses leaking from the laboratory."

They waited in the rest area for a while. Wang Xiaoxiao walked into the lounge wearing clothes that seemed to be made of plastic and a round glass helmet.

He greeted everyone with a smile, and walked directly to the professional equipment placed in the corner, where a huge hood covered its head, and the glass helmet on its head was taken off after it came out.

Chen Jin asked curiously: "Husband, why didn't Director Wang take off the helmet himself, your design is too inhumane."

Zhou Yu explained to her: "The chemical protective suit that Director Wang is wearing is our chemical protective suit specially designed for viruses.

The chemical protective clothing is airtight, and a portable oxygen bag is built into the clothing, which can prevent any virus from invading the human body.

The helmet adopts a magnetic buckle, which requires special equipment to take it off, in order to prevent the magnetic buckle from being opened due to strenuous exercise or accidental touch of the switch. "

Zhou Yu asked Wang Xiaoxiao: "How is the HIV test preparation? Can I test Ms. Xiao?"

"Mr. Zhou, there is no problem at all in the laboratory. Take her to draw blood, and the test results will come out soon." Wang Xiaoxiao said confidently.

Professional researchers in the laboratory took Xiao Meiling to the treatment room, drew a small tube of blood, and took it to the laboratory for testing.

Zhou Yu said apologetically: "This detection method has just been developed, and the detection equipment has not been developed yet, so it can only be tested with laboratory equipment."

Chen Jin asked curiously: "How did you detect HIV so quickly, and how accurate is it?"

Zhou Yu said seriously: "This detection method has an accuracy rate of 100%. As long as the high-risk behavior lasts for more than a week, and there is HIV in the body, it will definitely be detected.

I will not explain the basis of human humoral immunity and cellular immunity, as you who are medical students understand it.

After HIV enters the human body, it directly attacks lymphatic T cells and uses them as host cells for self-replication.

After the HIV virus is detected by phagocytes or lymphatic T cells, it will release pheromones.

This pheromone recruits lymphatic T cells to attack infected cells and the virus itself.

It also stimulates lymphatic B cells to differentiate into plasma cells and memory cells. Plasma cells are used to produce antibodies and kill viruses in the human body in large quantities.

The conventional detection method is to detect the HIV antibody in the human body, and the plasma cells produce a large number of virus antibodies, which can be analyzed by the detection reagent.

We are detecting the pheromone transmitted by lymphatic T cells. As long as the lymphatic T cells detect HIV, there must be this pheromone in human blood. Without this pheromone, it can prove that the tested person is safe. "

As soon as Zhou Yu finished speaking, Wang Xiaoxiao came out of the laboratory. He held the test sheet and said in a deep voice: "Ms. Xiao, this is a nourishing medicine prescribed by our laboratory doctor according to your physical condition. The choice is based on the curative effect. The best combination with the lowest side effects."

Chen Jin's eyes were red, and she said in disbelief: "How could Sister Xiao get AIDS? The risk of her exposure is very low, and she paid such a high price to take the blocking medicine in time."

"Ms. Xiao does not have HIV in her body. This is the medicine prescribed by Xiao Lu in our laboratory. He is a professional Chinese medicine practitioner. I just saw Ms. Xiao's situation and learned about the type of blocking medicine she was taking.

She was given medicines to regulate her body, but we couldn't prescribe medicines even if she was really AIDS. "Wang Xiaoxiao said with some surprise.

"How can you speak out of breath, you scared me to death."

Chen Jin walked to Xiao Meiling again, and said happily, "Sister Xiao, you are finally safe now."

She was happy from the bottom of her heart and let go of a heavy psychological burden.

"Honey, I'll take Sister Xiao back, can you go?" Chen Jin looked up at Zhou Yu and asked.

"There are other things here in the scientific research center, you go back first."

Zhou Yu sent Chen Jin and the others away, and asked Wang Xiaoxiao, "Director Wang, how is the progress of HIV research and development?"

He already knew the progress of the AIDS virus in his heart, and the technology tree in his mind had changed.

He guided Wang Xiaoxiao to the content he saw from the technology tree through discussion.

In order to achieve this goal, Zhou Yu has been studying psychology hard. He is now a master in the field of psychology. Every subtle movement and expression can arouse people's emotions.

His seemingly ordinary words, coupled with his actions, can give people a strong psychological hint, making the other party focus on what Zhou Yu wants to say to him.

Wang Xiaoxiao said with a smile: "Mr. Zhou, after many experiments and studies, we have now confirmed that HIV and human herpesvirus-6 are closely related.

Our experimental results are basically consistent with the scientists' results reported by the American media decades ago.

Now they are looking for the specific relationship between the two viruses, preparing to control AIDS through the human herpes virus-6 virus vaccine, and trying to create a vaccine that is not afraid of HIV mutation through their similar characteristics. "

Zhou Yu pretended to be contemplative, sorting out his words in his mind.

His eyes lit up and he said: "The vaccine stimulates lymphatic B cells to produce antibodies, which are related to specific proteins on the surface of the virus, but HIV uses ribonucleic acid (RNA) as its genetic material, and its stability is not as stable as that of deoxyribonucleic acid (DNA).

The specific protein on the surface of the virus changes frequently. The current HIV virus is very different from the HIV virus discovered earlier. It is not feasible to solve the HIV virus through vaccines.

If only we could decipher the language of communication between HIV and the human herpesvirus-6 virus. "

Wang Xiaoxiao slapped his thigh and said pleasantly: "The reason why HIV can overcome the human immune system is that its host cells are lymphoid T cells. The ability of the human immune system to repair itself.

As long as we crack the communication code of AIDS virus, we can let the human immune system find the hidden AIDS virus through artificial guidance.

In this way, even if the AIDS virus cannot be eradicated, an AIDS virus treatment agent with very low side effects can be produced. "

Zhou Yu watched as Wang Xiaoxiao was finally guided in the right direction by himself.

He said with a smile: "Director Wang, you want to research in this direction. If viruses can communicate with each other, they must have their own language. If we decipher the language of viruses, we will definitely be able to find a way to solve it."
