Back To The Age Of The 80s

"Mr. Li, Mr. Liang."

"Mr. Li, Mr. Liang."

"Li, welcome back!" David in the laboratory put on a tall western gentleman's hat, and when he saw Li Zheng coming in, he stepped forward to embrace him strongly.

Anthony smiled on the side, **** it, got ahead of the cunning guy again.

The "bang" ribbon burst out from the hands of Zhang Yuejun and others, and instantly fell on Li Zheng and the others.

"Welcome home, boss!" everyone shouted in unison.

A warm current is flowing in Li Zheng's heart, home, I haven't heard this word for a long time.

I haven't seen each other for half a year, and Zhang Yuejun and Zhang Chao seem to have matured a lot, and they are already able to stand alone. Zhong Peng was still smiling, but his temperament was much calmer than half a year ago. Ma Wenmin changed his original simple image, dressed in a lady's suit, black stilettos, and a navy blue envelope with white stripes. In his hands, she looked like a strong woman in the 1980s.

"Director Ma, you are back." Ma Wenmin is now the director of the International Research Center for In Vitro Regeneration of Organs. He works in the United States for more than half a year.

"Boss, you are joking. You have finally returned to the laboratory, and we, who are subordinates, will naturally come back to greet him." After half a year, the grief faded slowly, and Ma Wenmin was obviously more cheerful.

Liu Sichao changed his clothes and walked over from his laboratory. He couldn't help laughing when he saw Li Zheng and Liang Zhe.

"It's just here, I've finished lunch." Liu Sizhao came by a plane earlier than Li Zheng. According to him, Li Zheng must have a celebrity sister picking up the plane, and maybe it will be on the news, so he won't join in the fun. Up.

Let this old boy talk.

Next, the members of the laboratory successively reported to Li Zheng about the work of the past six months. The joint experimental center of Ma Wenmin has tried to use human cartilage cells to construct a human nose. The pre-contour reconstruction is not a problem, but transplantation and rejection It became a problem in the whole experiment.

"The existing immunosuppressive agents do not seem to be friendly to organs regenerated in vitro." Ma Wenmin smiled bitterly. "However, the United Center has accelerated the research on new immunosuppressive agents. We believe that with our joint efforts, in vitro organ regeneration technology There will be no problem with the perfection."

Li Zheng patted her on the shoulder to express encouragement. The technology of in vitro regeneration of organs and the technology of infinite organ storage are the two key chess pieces for Li Zheng to lay out the future medical landscape, and there must be no mistake.

Zhong Peng, Zhang Yuejun, and Zhang Chao set up a joint research team to study a new functional liquid.

"The fifth-generation CT system has been widely used, but its cost is high, and the start-up fee for a test is often not affordable by ordinary people, and we have inspected the fifth-generation CT of Mary Hospital on the spot. The imaging effect is It is much better than the fourth generation, but it is still not intuitive enough. Careless doctors often miss one or two things."

"Our detection fluid, after being circulated in the human body, enters the CT system for detection, which will enhance the imaging effect. If CT imaging is a three-dimensional sketch map, our detection fluid will act as a marker pen." Zhong Peng Explained.

A hint of surprise flashed in Li Zheng's eyes. This is a very practical technology. "How is the progress?"

"The experimental effect is obviously still relatively rough. After all, there is no CT machine, let us keep repeating the experiment." Zhong Peng laughed.

Li Zheng rubbed his chin, "Go to find out which hospital has not introduced the fifth-generation CT system, and tell them that Li Zheng laboratory can provide free loans, as long as they cooperate with the laboratory to complete the CT imaging experiment, the specific conditions and repayment Detailed rules, Zheng Lingling, talk to them."

Zheng Lingling said with a smile.

After saying hello to the people in the laboratory, Li Zheng and Liang Zhe went up to the second floor of Laboratory 2.

"In the past few days, I have to sort out some information, and I may be a little ignorant of you." Li Zheng said, he felt that his partner was not so competent.

Liang Zhe shook his head with a good temper, "It's great to see you and eat together."

Looking at Liang Zhe’s serious eyes, Li Zheng felt overwhelmed with guilt for an instant. He took the initiative to hug Liang Zhe and rubbed his chin on his shoulder. “Sorry, I won’t be able to give it anymore. This kind of promise, but I promise that I will try my best to adjust my work and life conditions."

Liang Zhe rubbed Li Zheng's hair, a trace of gentleness appeared in his eyes.

After Liang Zhe consciously went to work in the nearby study, Li Zheng quickly went to work. He writes as if there is a god, a brand new leather notebook, from time to time the words tumor, targeting, gene appear, surprisingly Li Zheng is the most familiar field in his life, anticancer drugs.

Anticancer drugs are the field that Li Zheng is most familiar with. In his previous life, he even stepped into the door to combat cancer with one foot. Why has he been so long in his life that he hasn't conducted research in this area? The backwardness of the experimental environment is one reason, and more importantly, the Human Genome Project has not started.

Cancer is caused by genetic mutations. Before the correct understanding of cancer and the discovery of cancer mutation genes, humans' medical treatment against cancer cells is chemotherapy, which kills cancer cells and normal cells together.

Just like a crop, as long as there are insects in the field, all the crops will be destroyed, leaving only a bare piece of land.

Gene mutations cause cancer, and the only thing that can truly conquer cancer is to correctly understand the gene and target it.

Today in the 1980s, the Human Genome Project has not yet begun, and most people's understanding of genes is still stuck in Watson's DNA double helix structure in 1953. Just rebirth and return to the era before the advent of the great voyage. Without a complete map of the world, who can believe someone said to him that there is a new continent on the opposite side of this sea with gold mines. Not to mention that life science is a science that pays attention to data, and every step of the experiment requires huge data to support.

Li Zheng cannot be allowed to complete the identification and identification of human genes alone. We must know the huge amount of work, but scientists from all over the world joined together and spent more than a decade without completing it.

The beginning of the Human Genome Project gave Li Zheng an opportunity. He wanted to participate in this great project, not only to solve the principles and mysteries of the disease, but also to regain his familiar field, the cancer target. Xiangyao!

In 1997, rituximab, the first cancer-targeted drug in history, was approved for marketing by the FDA. It used CD20 as a target to treat non-Hodgkin's lymphoma, opening a new chapter in the fight against cancer in humans.

Li Zheng is confident that this new chapter will come earlier and earlier.

What he has to do now is to make a semi-finished targeted drug experiment record. He uses it to convince Watson and tells him that he has reached the threshold of anti-cancer and gene targeting. As long as he participates in the Human Genome Project, perhaps humans will overcome Cancer will no longer be a dream!

In this regard, Li Zheng broke out with unprecedented enthusiasm, experimenting, recording, re-experimenting, and re-recording. Even if the direction of the experiment is clear, making a substantial and persuasive semi-finished product record is not much easier than completing a project.

Had it not been for Liang Zhe to report every day and pull him out of the laboratory for a meal, Li Zheng would have liked to spend it in the laboratory 24 hours a day.

"Ten minutes, Azhe, give me another ten minutes. You don't understand the feeling that the dream you have longed for for a long time will be realized in front of your eyes." Li Zheng said as he stared at the computer screen. Graph.

This working state Li Zheng lasted for more than two months.

At the end of May 1986, Li Zheng finally walked out of the laboratory. He was holding a thick document full of handwritten and machine-typed text, chaotic and organized.

"Lee, although Professor Watson is a very casual and refreshing person, are you sure you want to meet him with such a face?" David showed an exaggerated expression.

Li Zheng, who successfully completed the work, obviously had a joking mind.

"David, wipe off the coffee froth from the beard, this is more convincing."

David gave a weird cry, wiped his mouth with his black suit sleeve, and got Anthony's disgusting look.

Li Zheng shrugged, hesitated, and went into the bathroom.

Seeing his unkempt face in the mirror, there are many dense cyan stubble on his face, and he froze in place.

Thinking of Liang Zhe's unchanging good morning kiss in the past few days, he confirmed this fact again. Liang Zhe really loved him.

**

In the early morning of Xiangjiang time, Li Zheng called the father of DNA, James Dewey Watson.

Li Zheng and Watson are also old acquaintances. After graduating from Stanford in his previous life, Li Zheng was led by his mentor into the Cold Spring Harbor Laboratory, while Mr. Watson has been the director of the Cold Spring Harbor Laboratory in Long Island, New York since 1968. Short working time.

Later, Li Zheng returned to China and engaged in research on tumors and anticancer drugs. Watson also gave him a lot of help.

"Mr. Watson, hello. This is Li Zheng, yes, my laboratory has contacted you."

"If it's convenient for you, I hope I can meet you once."

Watson on the other end of the phone felt very surprised, but with Li Zheng's current international status, although he could not compare with a heavyweight international biology expert like him, he already had an equal opportunity to talk to him.

"Of course, Mr. Li, if you come to New York, I welcome you to Cold Spring Harbor as a guest." Watson said very politely.

Watson admired this young pharmaceutical genius very much. He felt that Li Zheng and himself were the same kind of people. Watson discovered the double helix structure of DNA at the age of 25, and he was called the father of DNA, and established his unshakable position in the history of biology.

And Li Zheng developed the first drug at the age of 16, and later it was a succession of high output, which won him the reputation of pharmacy genius, and his work in Africa is also very appetizing of Watson, and Americans like it. Hero, and Watson is a typical American.
