Back To The Age Of The '80s

Different from the new application in CH5 solution, organ freezing is an applied project.After the results of this project come out, it is not for pharmaceutical companies, but for organ centers and hospitals. It needs a universal technical standard.

For example, the selection of blood substitutes, the flow rate and temperature of blood entering the heart and vessels, etc., every detail needs to be compared, selected, and confirmed through countless tests, and each selection confirmation requires huge data to support the argument. This kind of experiment is extremely testing the level of a laboratory.

Even with the assistance of supercomputers, it took nearly four months for everyone in the laboratory to complete the preliminary data measurement.

"Li Zheng, the thawed heart cells remain intact, and there are no major technical problems, but experiments at this stage show that simple freezing cannot keep organs stored indefinitely." Liu Sichao took off his mask and said with a frown.

Li Zheng pursed his lips, and quickly flipped through the experimental records in his hands. Both he and Liu Sichao were masters in experimental manipulation. This experiment was done by the two of them themselves, and the technical operation was almost perfect.

Li Zheng closed the experiment record in his hand and said, "Meng Jie, Zheng Guangye, you four should do it once for us to see."

"Okay...okay, Li...Professor Li!" Meng Jie was so excited that his stuttering improved a lot.

Zheng Guangye also showed a hint of joy on his face. Since the conversation in the greenhouse, he discussed his future development path with his family when he returned home.After this project is over, he will leave the laboratory and join a ministry in Huajing.

Zheng Guangye's hand holding the experiment notebook was tight. Before leaving, he wanted to make something to commemorate his seven years of biology career.

"The computer has been debugged and the No. 1 solution is ready."

"No. 1 liquid fills in, and the external interface controls the flow rate."

"Lu Ke, Jiawen."

"Okay, the temperature is rising, 20, 25, 30, 40, the temperature rises to 50, reaches the optimal temperature, and the external interface is opened."

"No. 1 liquid flows into the heart, the temperature is normal, the flow rate is normal, and the sensor is normal."

Half of the monitors of the supercomputer are installed in the laboratory. Countless numbers flashed densely on the four monitors on the wall.

Li Zheng and Liu Sichao stood beside them, watching the movements of these four "little guys" without blinking, and their frowning brows did not loosen at all.

"The heart rate continues to slow down, Xiao Liu, highlight the heart data!" Sun Bin shouted loudly to Xiao Liu in the glass compartment next to him.

Xiao Liu kept typing on the keyboard with both hands, and when he heard Sun Bin's shout, he raised his hand to give him an OK gesture.

With the introduction of the No. 1 blood substitute liquid, as well as the changes in temperature and flow rate, the beating speed of the heart slowly decreased and gradually stabilized, keeping it at the minimum without loss of heart activity.

"These little guys are very good." Liu Sichao praised rarely.

Indeed, although they did not know how many times this experiment had been done in the past four months, it was all led by Li Zheng and Liu Sichao. It was the first time for the four of them to do it themselves, and it was already very remarkable to be able to do this to this extent.

however……

The "beep beep" heart detection sent out an alarm, and the broken line on the screen became smoother at a speed visible to the naked eye.

"Heartbeat drops! Quick! Adjust the temperature and flow rate! Prepare the human body simulation environment! Quick!" The four people panicked when they heard the siren. Even though Zheng Guangye reacted immediately, the data on the sensor was getting smaller and smaller.

"Beep..." With a gentle beep, the fluctuating lines on the screen turned into a straight line, and the heart stopped beating!

The faces of the four were pale.

"Professor..." Sun Bin drooped his head.

The corners of Li Zheng's mouth curled slightly, but he quickly turned serious, "Try again!"

The four of them were shocked, Zheng Guangye pursed his lips, and said: "Computer is ready, do it again!"

After repeating it five times, the four finally reached the thawing stage and carefully neutralized the liquid nitrogen to thaw the heart. The results of the experiment were the same as those of Li Zheng and Liu Sicong. The cells were not damaged, but the activity of the heart was also weakened during freezing.Simple freezing cannot achieve unlimited storage of organs.

"It's anti-corrosion. One less low-temperature anti-corrosion process!" Li Zheng said in a deep voice.

When Liu Sichao heard the words, he thought for a moment and nodded.

Although they knew the missing steps in the technical process, the Ninth Laboratory tried countless existing low-temperature antiseptic formulas, and none of them could meet the requirements of their experiment. In other words, their experiment got stuck.

This card is stuck until 1986.

During this period, Liang Zhe flew over twice, because Li Zheng was still in the project research stage, and the two of them couldn't speak a word at all. Li Zheng really felt that Liang Zhe didn't break up with him, it was definitely true love.

In January 1986, Zhao Depei personally came to "warn" Li Zheng that he had been absent from school for a long time.Huaqing has a rule that no matter how big a professor is, one class a month must be guaranteed. This provision was also included in the appointment letter signed by Li Zheng and Huaqing at the beginning, but Li Zheng was so confused by this project during this period that he completely forgot This crop.

And the leaders of Huaqing were also devoting themselves to the establishment of Huaqing Awards, and they didn't care about it. No, Zhao Depei came to him when he was free for a while.

Li Zheng rubbed his temples, "Okay, you can arrange the time." He replied like this.

So the next morning, Li Zheng stood on the podium in the classroom on the first floor of the teaching and research building.

The classroom was densely packed with people, and many of them brought their own stools to sit in the aisle of the classroom.

The people sitting in the first few rows are all older, some familiar and some unfamiliar, probably faculty and staff of Huaqing and other schools.By the way, the materials that Li Zheng compiled and narrated in the last public class have been proofread by Huaqing University Education Press, and they were officially published at the end of 85.

It was listed as a designated book for biological laboratories by the Huaguo Research Institute, and the biology departments of many universities in Huaguo also included it in the textbook list. This "Guide to Biological Research" is also one of the important reasons why the classroom is full this time. .

Li Zheng rubbed the watch on his wrist with some guilt. Compared with last time, he didn't prepare anything this time, what are he talking about.

Looking at the neatly arranged notebooks on the desks of his colleagues in the first few rows, Li Zheng squinted his eyes, and still had to talk about something meaningful.

What he is familiar with, has content, and what he can talk about on the spot without making preparations now is the ongoing project of "extending the duration of organ storage".

"Our class today discusses the current experimental project of the Ninth Laboratory, organ storage."

"I believe that everyone is familiar with this topic. After all, the dispute between UW solution and CH5 solution was raging last year. What I want to talk about today is the second phase of this project, the infinite storage of the heart."

The classroom immediately remembered the sound of rustling discussions. Although Li Zheng mentioned this concept as early as when Chicago TV station was at the beginning, and the domestic media also reprinted and reported it, ordinary people look at the problem, and professionals look at the problem. The depth is still different.

The experts and scholars in the front row realized the significance of this topic as soon as they heard it. The heart is the most precise organ in the human body outside the brain. The success of the heart’s infinite storage means that organ storage will enter a permanent era.

"Professor Li, is this really possible with the current level of technology?" A middle-aged man in the second row couldn't help asking.

He is an associate professor of biology at Yanda University. Yesterday, I heard that Professor Li from Huaqing was going to take a class. The biology department of Yanda University exploded instantly. All the professors didn't even want to go to the class. The problem of going to Huaqing to attend lectures.

Whether they want to go or not, of course they do, but Huaguo people love face, and Huaguo scholars are the best among them. Although Huaqing and Yanda are sister schools, the two schools are both in Huajing, and they are also one of the best universities in Huaguo. This competitive relationship is naturally indispensable.

They are dignified professors from Yan University, and they went to listen to a lecturer from Huaqing, which is too shameful!That's right, although everyone in Huaqing called Li Zheng a professor, in terms of his professional title, he was just a lecturer.

But don't go!How can that work!

They also read "Guide to Biological Research". This book almost sums up the development of biology from its inception to the present, lists the major experimental projects in the history of biology by category, and analyzes the experimental process Skills, summed up.

This group of Yanda professors read it over and over again, saying that they have benefited a lot or underestimated its role.

In case that Professor Li Zheng still hides something, in case the Huaqing group of guys really self-censors and does not print and publish it in a book, where are they going to cry, so they struggled for a day, these Yanda professors still decided to Come to class.

"Of course." Li Zheng said with a smile, "Now the Ninth Laboratory has frozen the heart without damage, and extended the storage time of the heart from 72 hours announced by the American Organ Transplantation Society to 168 hours. This is also a breakthrough in the history of organ storage. sexual progress."

"Of course, there is still a big gap between 168 hours and unlimited storage, but the road always takes the first step, doesn't it?" Li Zheng replied with a smile.

The discussions in the classroom got louder, 96 hours!

Professor Li said lightly, but the people under the podium knew what these 96 hours represented. The storage time of organs has been extended by more than double, which means that countless people will benefit from it, because this technology regained newborn.

After a while of discussion, they quickly quieted down and held their breath while listening to Li Zheng on the podium describe the specifics of the laboratory project.
