"Mr. Li, Mr. Liang."
"Mr. Li, Mr. Liang."
"Li, welcome back!" David in the lab wore a tall western gentleman's hat, and when he saw Li Zheng coming in, he stepped forward and hugged him.
Anthony smiled on the side, damn it, got the first move by that sly guy again.
The "Bang" ribbon burst out from Zhang Yuejun and the others, and instantly fell on Li Zheng and the others.
"Welcome home, boss!" Everyone shouted in unison.
A warm current was flowing in Li Zheng's heart, "Home, I haven't heard this word for a long time."
I haven't seen each other for more than half a year, but Zhang Yuejun and Zhang Chao seem to have matured a lot and are already able to take charge of themselves. Zhong Peng is still smiling, but his temperament is much calmer than half a year ago. Ma Wenmin changed his original simple image, wearing a lady's suit, black stiletto heels, and a navy blue envelope bag with white stripes. In her hand, she looks like a strong woman in the 1980s.
"Director Ma, you're back too." Ma Wenmin is now the director of the International Research Center for In Vitro Regenerating Organ Technology, and works in the United States for more than half of the year.
"Boss, you're joking. You finally returned to the laboratory once, and our subordinates will naturally come back to welcome you." Half a year was enough time for the grief to slowly fade away, and Ma Wenmin was obviously a lot more cheerful.
Liu Sichao changed his clothes and walked over from his laboratory. When he saw Li Zheng and Liang Zhe, he couldn't help laughing.
"I just arrived, I have already finished my lunch." Liu Sizhao came by a flight earlier than Li Zheng. According to his words, Li Zheng must have a celebrity sister to pick up the plane, and maybe it will be in the news, so he will not join in the fun .
But let the old boy speak.
Next, the members of the laboratory reported to Li Zheng about their work for the past six months. The joint experimental center on Ma Wenmin's side has already tried to use human cartilage cells to build a human nose. The reconstruction of the contour in the early stage is not a problem, but transplantation and rejection became the problem in the whole experiment.
"Existing immunosuppressants don't seem to be very friendly to organs regenerated in vitro." Ma Wenmin showed a wry smile, "However, the Joint Center has accelerated the research on new immunosuppressants. We believe that with our joint efforts, the technology of organ regeneration in vitro will be developed. Perfection will not be a problem.”
Li Zheng patted her on the shoulder to express his encouragement. In vitro regenerative organ technology and infinite-time organ storage technology are the two key pieces for Li Zheng's layout of the future medical landscape, and he must not go wrong.
Zhong Peng, Zhang Yuejun, and Zhang Chao established a joint research group to study a new functional liquid.
"The fifth-generation CT system has been widely used, but its cost is high, and the start-up cost of a test is often not affordable for ordinary people, and we have investigated the fifth-generation CT in Queen Mary Hospital on the spot, although the imaging effect is not affordable. It's much better than the fourth generation, but it's still not intuitive, and careless doctors often miss a thing or two."
"Our detection solution, after the human body circulates for a circle, enters the CT system for detection, which will enhance the imaging effect. If CT imaging is a three-dimensional sketch map, our detection solution will play the effect of a marker pen." Zhong Peng explained.
A hint of surprise flashed in Li Zheng's eyes, this is a very practical technique, "How's it going?"
"The effect of the experiment is obviously still relatively rough. After all, there is no CT machine, so let's keep repeating the experiment." Zhong Peng said with a smile.
Li Zheng rubbed his chin, "Go and ask, which hospital has not introduced the fifth-generation CT system, and tell them that Li Zheng's laboratory can provide free loans, as long as they cooperate with the laboratory to complete the CT imaging experiment, the specific conditions and repayment Details, Zheng Lingling, talk to them."
Zheng Lingling said with a smile.
After greeting the people in the laboratory, Li Zheng and Liang Zhe went to the second floor of the No. 2 laboratory.
"In the past few days, I have to sort out some information, so I might be a little bit careless 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 good to see you and have dinner together."
Looking at Liang Zhe's serious eyes, Li Zheng suddenly felt a sense of guilt, he took the initiative to hug Liang Zhe, rubbed his chin on his shoulder, "I'm sorry, I won't be able to give this anymore. It's a promise, but I promise I'll try to adjust my work and life as much as possible."
Liang Zhe rubbed Li Zheng's hair with a hint of tenderness in his eyes.
After Liang Zhe consciously went to work in the study next to him, Li Zheng quickly went to work. He wrote like a god. In a brand-new leather notebook, the words tumor, target, and gene appeared from time to time. It was the field that Li Zheng was most familiar with in his previous life, anticancer drugs.
Anticancer drugs are the field that Li Zheng is most familiar with. In his last life, he even stepped into the door of conquering cancer with one foot. Why has he been slow to conduct research in this area in his life? One reason is that the experimental environment is lagging behind, 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, the medical method for human beings to fight 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, the whole crop will be destroyed, leaving only a bare land.
Gene mutation causes cancer, and the only way to truly overcome cancer is to correctly understand genes and target them.
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. It's like being reborn back to the era before the advent of the Great Voyage. Without a complete world map, who can believe that someone told him that there is a new continent on the opposite side of this sea, with gold mines on it. Not to mention that life science is a science that pays attention to data, and every experimental step requires huge data to support.
Li Zheng could never be allowed to complete the identification and identification of human genes alone. You must know that this workload is huge, but it took scientists from all over the world to work together for more than ten years to complete it.
The start of the Human Genome Project gave Li Zheng an opportunity. He wanted to participate in this great project, not only for humans to understand the principles and mysteries of diseases, but also to regain his familiar field, cancer targets. To medicine!
In 1997, the first cancer-targeted drug rituximab in history was approved by the FDA. It targets CD20 for the treatment of non-Hodgkin's lymphoma, opening a new chapter in the fight against cancer.
Li Zheng is confident that this new chapter will come earlier, earlier.
What he has to do now is to make a semi-finished experimental record of targeted drugs. He uses it to convince Watson that he has reached the threshold of anti-cancer and gene targeting. As long as he is allowed to participate in the Human Genome Project, perhaps mankind will overcome Cancer will no longer be a dream!
In response, Li Zheng exploded with unprecedented enthusiasm, experimenting, recording, re-experimenting, and re-recording. Even if the direction of the experiment is clear, it is not much easier to make a substantial and convincing record of semi-finished products than to complete a project.
If Liang Zhe hadn't come to report every day and pulled him out of the lab to eat, Li Zheng would have wanted to be in the lab 24 hours a day.
"Ten minutes, Azhe, give me another ten minutes. You don't understand the feeling that the dream you've been dreaming about for a long time is about to come true in front of your eyes." Li Zheng said while staring at the words on the computer screen. Graph.
Li Zheng continued in this state of work for more than two months.
At the end of May 1986, Li Zheng finally walked out of the laboratory, holding a thick document filled with handwritten and machine-typed text, chaotic and organized.
"Li, although Professor Watson is a very casual and straightforward person, are you sure you want to see him with such a face?" David showed an exaggerated expression.
Li Zheng, who had successfully completed his work, obviously had the intention of joking.
"David, wipe the coffee foam off your beard, that's more convincing."
With a strange cry, David wiped his mouth with the sleeve of his black suit, receiving a disgusting look from Anthony.
Li Zheng shrugged, hesitated for a moment, and walked into the bathroom.
Seeing his unkempt face in the mirror and the appearance of many fine cyan stubble on his face, he froze in place.
Thinking of Liang Zhe's unchanging good morning kiss these days, he confirmed the fact again that Liang Zhe really loves him.
**
In the early morning of Hong Kong time, Li Zheng called the father of DNA, James Dewey Watson.
Li Zheng and Watson are also old acquaintances. In the last life, after graduating from Stanford, Li Zheng was led by his mentor to enter the Cold Spring Harbor Laboratory, and Mr. Watson has been the director of the Cold Spring Harbor Laboratory in Long Island, New York since 1968. That is to say, Li Zheng and Watson in the previous life had a relationship. 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.
"Hello, Mr. Watson. I'm Li Zheng, yes, my laboratory has contacted you."
"If it is convenient for you, I hope I can meet you once."
Watson on the other end of the phone was very surprised, but with Li Zheng's current international status, although he couldn't compare to a heavyweight international biology leader 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." Watson said very politely.
For this young pharmaceutical genius, Watson is very much appreciated. 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 was known as the father of DNA, establishing himself as an unshakable position in the history of biology.
And Li Zheng developed his first drug at the age of 16, and later achieved high output, earning him the reputation of a pharmaceutical genius, and his work in Africa was also very appealing to Watson, and Americans like it Hero, and Watson is a typical American.
