After the donation ceremony by Roche and Huaqing, the University of Chicago took the initiative to come to Huaqing University to carry out a scientific research cooperation project on "extending the storage time of human transplant organs".
"A reference table for organ refrigeration published by the American Organ Transplant Association this year stated that under current technical conditions, the refrigeration time limit for the heart is 3-5 hours, the liver is 24 hours, the kidney is 48-72 hours, and the bone marrow is 5 years. The storage time is too short to meet the needs of cardiovascular patients, so both the University of California and the University of Chicago are working to develop improved organ tissue delivery devices."
"My laboratory is also ranked in Asia in terms of organ transplantation. Li Zheng, I have read your laboratory's paper on 'regenerating organs in vitro', which is a major advance in tissue engineering. If In vitro regeneration technology and organ transplantation can be combined, which will be a great contribution to the history of human medicine!"
Speaking of this, Meng Lao danced with excitement.
He looked at Li Zheng with burning eyes, and his eyes were full of anticipation.
"Meng Lao, if the 'in vitro regeneration organ' technology can be further developed, I would be very happy to cooperate with your laboratory to promote the combination of the two technologies."
"Good, good." Meng Lao said three good words in a row. Rao is that he knows that it takes not one day or two days for these two technologies to develop to the ideal stage. Maybe by that day, he will no longer be there. But in the eyes of the older generation of scientific researchers, as long as there is hope and feasibility, it is worth working hard.
What's more, these two technologies are completely feasible in theoretical deduction, only a technological breakthrough is needed, and it is only a matter of time before reaching his ideal stage.
In the next two months, in addition to remotely commanding related projects in Li Zheng's laboratory, Li Zheng devoted more energy to promoting international drugs to enter the Chinese market as soon as possible.
Nowadays, Li Zheng has good cooperative relations with international pharmaceutical companies such as Roche, Pfizer, and Merck. With his mediation, it is not impossible for advanced drugs to enter the Chinese market early.
"Li Zheng, are you in a hurry to start this matter now?" Zhao Depei was full of admiration for this upstart in biology, but even so, he was still a little stunned when he heard what Li Zheng was going to do. .
This young man really dares to think!
"These things are not only academic matters, but also related to policy. To synchronize the domestic drug market with the international drug market, not only people must be willing to come in, but we must also be willing to let them in." Zhao Depei carefully considered the language, he did not want to attack The positivity of young people, especially the positivity of young people who have a country in their hearts.
"Principal, if you don't do something, how do you know it's impossible. Huaqing and Yanda are the highest universities in China, many leaders come from these two universities, and policies are also made by people. As long as they are people, they can be flexible. It can be modified, can't it?"
"We scholars spend half our lives in the laboratory, but the drugs we developed can benefit foreigners, while the drugs developed by foreigners cannot benefit our people. Is it fair?"
Zhao Depei frowned tightly, his index finger and thumb rubbed unconsciously, thinking that he was seriously considering it.
"Li Zheng...you let me think about it, think about it."
Li Zheng understood Zhao Depei's concerns, he rubbed his eyebrows, and took out a piece of white paper from his trousers pocket.
Li Zheng handed the white paper to Zhao Depei, "This is the next project schedule of my Li Zheng laboratory, maybe you will be interested in the principal. Because of patent reasons, I will still put these projects under the name of Li Zheng laboratory, and I will keep the project under the name of Li Zheng's laboratory. Through the channels of international pharmaceutical companies, I don’t want the drugs that I have worked so hard to develop to benefit the people of the world but to be alone in my compatriots.”
Zhao Depei was startled. He took the white paper, unfolded it, and then stood up abruptly, "These medicines...you, you are sure." His voice trembled slightly.
Not all of them, as long as one of them can be realized, it is enough to set off a medical revolution, anti-cancer drugs, this... This is a problem that the whole world is trying to overcome, Li Zheng laboratory, how is it possible.
But without anticancer drugs, these antibiotics, or vaccines, are enough to drive the medical world crazy.
"Principal, this is the plan of Li Zheng's laboratory, and it is also the plan of the world's biological community. It will be a matter of time before these drugs come out. If they come out, but our masses can't enjoy them, can we scholars feel at ease? ?"
Zhao Depei gave Li Zheng a deep look, "You are amazing, you convinced me. I will work hard, but it will be a long-term process."
"I know." Li Zheng's mouth twitched slightly. In his last life, the country did not substantially reduce or exempt anticancer drug tariffs until 2018. He paid attention to the synchronization of the international drug market and the domestic drug market. On the surface, it is already a big improvement.
Zhao Depei will do what he says, and since he has agreed, he will work hard to do it. In the past two months, the two of them wanted to put all their energy into this matter.
Therefore, when they heard that Meng Lao was admitted to the hospital because of cardiovascular disease, they were all shocked.
"When did it happen? Why didn't anyone notify me?" Zhao Depei yelled into the phone.
"It's been three days, coronary atherosclerosis, and the situation is not optimistic." Chen Anbang's voice was low and solemn.
Zhao Depei hung up the phone heavily, "Li Zheng, let's see Elder Meng in my drug hospital."
"I'll go with you." Li Zheng's expression was also solemn.
Mr. Meng is a scholar he admires very much. When he came to Huaqing in his last life, Mr. Meng had already passed away. Thinking about the time of his teacher's death that Chen Anbang described to him, it seems like... 1985.
His heart shrank suddenly. Two months ago, Meng Lao was still in high spirits and told him the technology of "extending the storage time of human organ transplantation"...
When the two drove to the hospital, Meng Lao had already been pushed into the intensive care unit.
Several people from Chen Anbang and Meng Lao's laboratory stood at the door with sad expressions on their faces.
Mrs. Meng passed away three years ago, and the two did not leave any children. Mr. Meng was completely alone and took the laboratory as the focus of his entire life.
"The teacher has always suffered from angina pectoris, but because of the busy project, he has not paid attention to it. Coronary angiography shows that the first diagonal artery of the left anterior descending artery is narrowed before the branch, and the blood cannot flow normally. The doctor said that there are about three more month."
There was silence in the hospital corridor.
Li Zheng didn't like this kind of atmosphere of life and death, never.
Chen An wiped his red eyes, "Principal, Li Zheng, since you are here, go see the teacher. The teacher is in a good state of mind now."
Li Zheng and Zhao Depei nodded and followed Chen Anbang into the ward.
Meng Lao, as a national treasure-level scientist, lives in an intensive care unit. The room of about 30 square meters has a separate bathroom and a small TV.
The sunlight fell on the white hospital bed through the window. When Li Zheng saw Meng Lao at this time, he couldn't help feeling sour. There was hardly a trace of black hair on Meng Lao's head, and the whole person seemed to be several years old. The sense of vicissitudes of human beings diffused from him, giving people a feeling of sunset and western mountains.
"Teacher, the principal and Li Zheng have come to see you." Chen Anbang said softly.
When Old Meng heard the words, he turned his head slowly and saw the two of them with a smile on his face.
"You are here, sit down."
The two agreed and sat down on the stool in front of the hospital bed.
"Xiao Zhao, I'm afraid I won't be able to continue with the project in Chicago. But Huaqing has little experience in participating in international projects, so I can't just give up this opportunity. Anbang has been with me for a long time, and I hope he can do this project for me. down."
Zhao Depei heard Meng Lao's words as if explaining his last words, his eyes were red, and his voice trembled slightly, "Okay."
"Why are you crying? It's just that the person in charge has changed. I don't know if there will be any opinions on the Chicago side." Meng Lao muttered to himself, then looked up at Chen Anbang, "Anbang, there are still three months, these three months. I will take you to do projects here, meet people from the University of Chicago, and you have to seize the opportunity yourself.”
When Mr. Meng talked about the project, he felt much better, and a hint of rosy appeared on his pale cheeks.
"Teacher! You need to rest now!" He naturally understood the meaning of Meng's old words. In the last three months of his life, he actually planned to continue participating in the experiment.
"You." Elder Meng waved his hand, "It's a waste to lie in bed for three months. Naturally, it's better to be in the laboratory. Even if I die in the laboratory, I'll be happy!"
Almost everyone present except Li Zheng had their eyes moistened.
Emotions are very contagious. Seeing everyone like this, Meng Lao couldn't help showing a trace of sadness in his eyes.
As soon as Li Zheng entered the ward, he did not greet Elder Meng, but picked up Elder Meng's reports from the bedside table next to the hospital bed and checked them carefully.
Medicine does not divide, although Li Zheng's clinical ability is not as good as that of a front-line doctor, but his theoretical knowledge is very rich. Coronary artery stenosis was almost an incurable disease in China in the mid-1980s, but Li Zheng remembers that in the world, there are still treatments.
In September 1977, Grusziger used a balloon catheter to dilate a patient's narrowed coronary artery, which was the world's first coronary angioplasty.
The 1978 Medical Journal featured this new technology in literature.
"Coronary angioplasty!" Li Zheng said suddenly, "Although PTCA technology is not yet fully mature, it has been in clinical practice for many years, why don't we give it a try?"
