Chapter 142：

After the donation ceremony of Roche and Huaqing, the University of Chicago took the initiative to come to the door to conduct a scientific research cooperation project with Huaqing University on "extending the storage time of human transplanted organs".

"An organ cold storage reference table published by the American Organ Transplantation Association this year stated that under current technical conditions, the cold storage time of 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 the University of California and the University of Chicago are working hard to develop and improve organ tissue delivery devices."

"My laboratory is ranked top in Asia for organ transplantation. Li Zheng, I have read your laboratory's paper on'in vitro regeneration of organs'. This is a major advancement in tissue engineering. The combination of in vitro regeneration technology and organ transplantation will be a great contribution to human medical history!"

Speaking of this, Meng Lao danced excitedly.

He looked at Li Zheng with scorching eyes, with a look of expectation in his eyes.

"Meng Lao, if the'in vitro regenerative organ' technology can be further developed, I will be happy to cooperate with your laboratory to promote the combination of the two technologies."

"Good, good." Meng Lao said three good words in succession. He knew that it would not take a day or two for these two technologies to develop to the ideal stage. Perhaps he would be gone by that day. But in the eyes of the older generation of scientific researchers, as long as there is hope and feasibility, it is worth the effort.

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 directing the related projects of Li Zheng's laboratory, Li Zheng focused more on promoting international drugs to enter the Chinese market as soon as possible.

Nowadays, Li Zheng has a good cooperative relationship with Roche, Pfizer, Merck and other international pharmaceutical companies. With his mediation, it is not impossible for advanced drugs to enter the Chinese market early.

"Li Zheng, you are embarking on this matter now, are you in a hurry?" Zhao Depei was full of admiration for this upstart in biology, but even so, he was still a little surprised when he heard what Li Zheng was about to do. .

This young man really dare to think!

"These things are not only academic matters, but also related to policies. To synchronize the domestic drug market with the international drug market, not only people are willing to come in, but also we are willing to let people in." Zhao Depei carefully considered the language, he did not want to attack The enthusiasm of young people, especially the enthusiasm of this kind of young people with their homeland.

"President, there are things you don’t do, how do you know that it’s impossible. Huaqing and Yanda University are the highest universities in China. Many leaders come from these two universities. Policies are also made by people. As long as they are people, they can be flexible. It can be modified, can't it?"

"Our scholars spend half their lives in the laboratory, but the drugs we develop can benefit foreigners, but the drugs developed by foreigners cannot benefit our people. Is this fair?"

Zhao Depei frowned tightly, and he rubbed his index finger and thumb unconsciously, thinking about it carefully.

"Li Zheng... You let me think again, think about it."

Li Zheng understood Zhao Depei's concerns. He rubbed his eyebrows and took out a piece of white paper from his trouser pocket. The edge of this white paper was cratered, and it was obviously torn off by the owner at will.

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. Through the channels of international pharmaceutical companies, it will be promoted to various countries as soon as possible. I don’t want my own painstakingly developed drugs that benefit the people of the world but lack my compatriots alone.”

Zhao Depei was startled, he took the white paper, unfolded it, and then stood up abruptly, "These drugs...you, you are sure." His voice trembled slightly.

Not all, 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, how is it possible in Li Zheng's laboratory.

But there is no need for anti-cancer drugs, just these antibiotics or vaccines are enough to drive the medical profession crazy.

"Principal, this is the schedule of Li Zheng's laboratory and the schedule of the world's biological community. It will be a matter of time before these drugs will appear. If they appear, but our masses will not enjoy them, can we scholars feel at ease? ?"

Zhao Depei took a deep look at Li Zheng, "You are great, you convinced me. I will work hard, but it will be a long-term process."

"I know." The corner of Li Zheng's mouth raised slightly. In his previous life, the country did not substantially reduce or exempt anti-cancer drug tariffs until 2018. He paid attention to the synchronization of the international drug market and the domestic drug market. In this life, he addressed this issue thirty years earlier. On the bright side, 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. During these two months, the two wanted to devote almost all their energy to this matter.

Therefore, when they heard that Meng Lao had entered the hospital due to cardiovascular disease, they were all shocked.

"When did it happen? Why was no one notified me?" Zhao Depei yelled at the phone.

"It has been three days, coronary atherosclerosis, the situation is not optimistic." Chen Angang's voice was low and solemn.

Zhao Depei hung up the phone again, "Li Zheng, see Lao Meng in my medicine hospital."

"I'll go with you." Li Zheng's expression was also a little 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 the teacher's death that Chen Angang described to him back then, it seems to be...1985.

His heart contracted suddenly. Two months ago, Meng Lao was still talking to him about the technique 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 a sad look on their faces.

Mrs. Meng passed away three years ago, and the two did not leave any children. Mrs. Meng was completely alone and made the laboratory the focus of all his life.

"The teacher has always suffered from angina pectoris, but because the project is busy, he has not paid attention. Coronary angiography shows that the first diagonal artery of the left anterior descending artery is stenosis before it separates, and blood cannot flow normally. The doctor said that there are probably three more. Month."

There was silence in the hospital corridor.

Li Zheng didn't like the atmosphere of life and death, never.

Chen An helped wipe the 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 walked into the ward behind Chen An's group.

As a national treasure-level scientist, Lao Meng lives in an intensive care unit. The room is about 30 square meters, with separate bathroom and small TV.

The sun fell on the white hospital bed through the window. Li Zheng couldn't help feeling sore when seeing Lao Meng at this time. There was almost no black hair on Meng Lao's head. He seemed to be several years old. People's vicissitudes of life overflowed from him, giving people a feeling of sunset.

"Teacher, the principal and Li Zheng came to see you." Chen Anbang said softly.

Hearing the words, Lao Meng slowly turned his head and saw the two of them with a smile on their faces.

"You are here, sit down."

The two of them sat down on the stool in front of the hospital bed.

“Xiao Zhao, I’m afraid I can’t do the project with Chicago. But Huaqing has little experience in participating in international projects, so I can’t just give up this opportunity. Anbang has been following me for a long time. I hope he will do this project for me. Go down."

Zhao Depei heard the words of Meng Lao as if he had confessed his last words, his eyes were red, and his voice trembled slightly, "Okay."

"What are you crying? It's just a change of person in charge. I don't know if Chicago will have any opinions." Meng Lao muttered to himself, then looked up at Chen Anbang, "Anbang, there are still three months, these three months Here I will take you on projects and meet people at the University of Chicago. You have to grasp the opportunity yourself."

When Lao Meng said about the project, his spirits improved a lot, and a trace of ruddy appeared on his pale cheeks.

"Teacher! You need to rest now!" He naturally heard the meaning of Meng's old saying. In the last three months of his life, he actually planned to continue participating in the experiment.

"You." Old Meng waved his hand. "These three months of lying in bed are also a waste. Naturally, it is better to be in the laboratory. Even if I die in the laboratory, I am happy!"

Almost everyone present except Li Zheng started to have some moist eyes.

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 Lao Meng. Instead, he picked up the reports of Lao Meng from the bedside table next to the bed and checked it carefully.

Medicine is not divided into families. Although Li Zheng's clinical ability is not as good as that of frontline doctors, his theoretical knowledge is very rich. Coronary artery stenosis was almost incurable and terminally ill in China in the mid-1980s, but Li Zheng remembered that in the world, there were still treatments.

In September 1977, Gruszieger used a balloon catheter to dilate the patient's narrowed coronary artery, which was the world's first coronary angioplasty.

The medical journal in 1978 published this new technology in literary form.

"Coronary angioplasty!" Li Zheng said suddenly, "Although PTCA technology is not fully mature yet, it has been in the clinic for many years. Why don't we give it a try?"
