godfather of surgery

Chapter 678 Small Experiment

Yang Ping rejected Lang Naifei's surgery invitation, Robert and August were very depressed.

However, Yang Ping is like a god in their hearts. Presumably the god-like professor has his own plans, and he is not interested in Lang Naife and its high-end technology.

The two quickly put the matter behind them and went to Yu Shuilian's bakery to have a few cups of coffee and some bread.

By the way, teach Yu Shuilian how to use the power brace mailed by Boston Dynamics. This pair of power braces was customized for Yu Shuilian by Boston Dynamics Laboratory using his personal relationship.

When Yu Shuilian puts on this brace, the stump of the whole body can sit firmly in the comfortable brace base, and then the two brace holders designed under the armpit also share part of the gravity, so that the whole body is supported by the brace, and Become one with the body.

As long as Yu Shuilian's brain has the idea of ​​walking, the electrical signals of the brain will be collected by the brace. This idea will cause subtle changes in the myoelectric signals of the upper limbs and body, and these subtle myoelectric signals will also be collected by the brace.

In this way, the computer chip will analyze and make a judgment based on the collected information: the owner needs to move his legs if he wants to walk, and the power brace will immediately move and start walking.And the longer the brace is used, the more coordinated the brace and the person will be, because the brace is always collecting data, optimizing its calculations, and making judgments more accurate.

The advanced power brace is the result of the comprehensive application of brain-computer interface technology, EEG technology and robotics technology. When the technology is mature, it will be a blessing for paralyzed patients.

Under Robert's patient guidance, Yu Shuilian has mastered the use of the brace, but it will take time and a period of time to master the brace and integrate the brace with the person.

The bakery located on the first floor of Sanbo Hotel has a very good business. It is a hodgepodge. In addition to all kinds of bread and pastries, there are also tea, coffee, milk tea, fruit juice. The spacious storefront can also arrange some seats for guests to sit down take a break.

Yu Shuilian and his wife’s baking level is definitely not bad. The baking master of the five-star hotel in Hong Kong taught the technique personally, and the couple also did it very carefully. From material selection, preparation to baking, every step is very attentive. This bakery has already gained a good reputation. Outside, the guests not only come from Sanbo Hospital and its surrounding areas, but also from other districts in the city.

If we say that when the store first opened, the store relied on the story of "half people" to attract customers, then now it completely relies on one baked food after another to attract customers. Additions, the boss is very reliable.

In the corner, two foreigners sat together, whispering.

The doctors and nurses who bought the bread were also used to these two people -- the red nose and the golden lion king. They knew that they were fellow doctors of general surgery, and they were said to be two international experts in orthopedics.

"Did you find out that the professor often closes the door and rests in the office."

"That's not rest, it's quiet thinking, geniuses are like this, they like to be alone."

"Before every major operation, he would close his eyes and rest in the locker room."

"I also discovered the details of the professor, so now before every major operation, I will look at my eyes in the locker room for a few minutes."

"Then what do you think about when you close your eyes and rest your mind? The details of the operation?"

"No, I'm thinking, what other Chinese delicacies I haven't eaten."
-
The next morning.

In the general surgery director's office, Yang Ping drank tea leisurely.

In the system space laboratory, after several months of hard work, Yang Ping finally solved the mystery of skin augmentation in vitro. According to his own induction theory, he found out the induction formula of skin augmentation technology. The formula is more advanced and perfect.

Because Yang Ping mastered several core principles of the induction theory, and then used these core principles to guide the experiment and find out the specific subdivision formula.

Back then, when Yang Ping was in middle school, his math teacher strongly recommended Euclid's "Elements of Geometry" to his classmates. 23 definitions, five postulates, and five axioms are given, and the entire geometric system is deduced and built.

At that time, every classmate in the class had a copy of "Principles of Geometry", and their math scores surpassed those of other brother classes. Every time in the big and small exams, everyone scored high in math, and the perfect score was everywhere.

In recent years, Yang Ping has read "The Principle of Everything", which is popular on the Internet. After studying it several times, he found that the way of thinking in it is exactly the same as "Elements of Geometry".

They all look at the essence through phenomena, analyze things, firmly grasp the basic principles behind things, and then use the basic principles to understand objects, build theories, guide practice, and finally achieve great innovation.

Following this thinking, Yang Ping found several basic principles for stem cells to be induced to differentiate: 1. Their induction is borne by some special substances, which can be proteins or other factors. 2. Various inducing substances form the inducing formula according to different amounts, and the composition of this formula is very precise. 3. Different directions and periods of differentiation require different induction formulas. 4. Factors other than inducing substances, such as temperature and internal environment, participate in the influence. 5. There is a certain internal logical relationship in the induction formula, they can turn on and off the genetic information in the cell, which is the basis of differentiation. 6. Whether it is the development process of embryo or the formation process of teratoma, the induction formula is similar.

Under the guidance of this basic principle, Yang Ping found the basic logic of the induction formula, and under the guidance of the basic logic, he was able to conduct experiments like ducks in water.

In the system space laboratory, as long as there are enough points, any experimental materials and equipment can be obtained instantly, and even if the experiment fails, there will be no adverse consequences except for the consumption of points, and the cost of trial and error is extremely low.

More importantly, experimenting in the system space does not consume real time, so that the time cost is zero.

But the points must be obtained in reality, either through successful surgery or the application of scientific research results.

So Yang Ping is more cautious and dare not use points indiscriminately. Now that there are enough points, a lot of points are needed to support the stem cell experiment, so the points cannot be consumed indefinitely, and the experiment must be carefully planned to avoid insufficient points during the experiment.

For example, in the current stem cell experiment, if the experiment in the system space runs out of points and has not been successful, it will be difficult to obtain so many points to support the experiment again. Even if it is necessary to accumulate so many points, it will take a long time.

Therefore, Yang Ping also made the experiment progress steadily step by step, so that the points entered a virtuous circle.

This is the same as investment, it must enter into a virtuous circle of value-added, and assets will snowball more and more.However, if you spend recklessly or make mistakes in your investment strategy, you will lose all your money, and it will be difficult to turn around.

Song Zimo knocked on the door of the director's office, and he brought Tang Shun to report.

Tang Shun finally dealt with his Ph.D. graduation from the University of Tokyo, and officially came to Sanbo Hospital to report to work as the director of the stem cell laboratory.

In fact, it didn’t take much time to graduate. The main reason is that Mr. Tang has too many girlfriends in Japan, from undergraduates, masters to doctors, and those who have already joined the work, so they can cover them all.

At the time of parting, every girlfriend should arrange time to comfort her. Only after the big circle is dealt with properly can Mr. Tang return to China with peace of mind.

After getting permission, Song Zimo pushed open the door, the tea on the table was steaming hot, and the aroma was overflowing. The professor was squinting his eyes halfway, and tapped the table lightly with his fingers. Seeing Song Zimo and Tang Shun, Yang Ping stopped tapping finger.

"Doctor Tang!"

Yang Ping immediately got up and held Tang Shun's hand.

"Professor Yang!"

Tang Shun seemed very excited. He came to Sanbo after careful consideration and full of longing for the future.

"Sit and drink tea!"

Yang Ping called everyone to sit down, and Song Zimo began to pour tea.

It's still early, even if there is a shift or something, with Xu Zhiliang as the host, everyone can sit down and have a good chat.

"Dr. Tang plans to officially start work today." Song Zimo cut to the chase.

Tang Shun arrived at Sanbo Hospital the night before, and rushed to see Yang Ping the next day, hoping to go to work as soon as possible.

"Then arrange it!"

Yang Ping didn't talk nonsense, he took out a piece of A4 paper from the drawer and handed it to Tang Shun.

"You came at the right time. This is a new experimental idea of ​​mine - skin in vitro amplification technology. You can try it out."

Tang Shun took the A4 paper, on which many things were densely written, read it quickly and said:

"Maninstein's in vitro skin amplification technology? Where did you get the induction formula?" Tang Shun was very puzzled.

Because the paper published by Maninstein did not disclose the specific induction formula. This induction formula is like a traditional Chinese medicine prescription. It only tells you the main medicines and does not tell you key information such as dosage. It cannot be used as a reference at all. use.

"This is my own induction formula, which may be more effective than Maninstein's. Let's do a small experiment in our own stem cell laboratory to see if it can be used and what the effect is. If it can be used, the effect is good. Our The next step of the topic will be clearer.”

Yang Ping's understatement made Tang Shun speechless.

What is it that his formula works better than Maninstein's?
Moreover, this cutting-edge stem cell technology is just a small experiment in his eyes?

In any case, this is a large-scale experiment with extremely high technical content, and the induction formula written on this paper requires a lot of experiments to obtain. It is still unknown whether Professor Yang can use it written out of thin air.

Whether it works or not, you will know if you try it.

Tang Shun analyzed the formula again. This "inducing formula" is very scientific and definitely not random.

There are several inducers that Tang Shun has discovered, but no papers have been published yet, and there are several inducers that Tang Shun has never seen.

It means that the induction factor in this formula is ahead of his own research, Tang Shun judged immediately.

"Professor, do you mean that you can do in vitro skin augmentation?" Song Zimo was very surprised.

In the past few days, Robert and August have been discussing this in vitro skin augmentation technology, and Song Zimo also understands that Yang Ping did not do any related research before, and now he suddenly took out such a piece of paper.

Yang Ping nodded: "I'm usually too busy and don't have time to do a lot of things. These days, August and Robert mentioned the in vitro skin amplification technology. It happened that Tang Shun was on the job. The stem cell laboratory can operate normally, so let's try it." For this little experiment, remember to call Robert and August together to participate."

Randomly Yang Ping ordered Song Zimo: "Go and see if there is any troublesome patient with large scars in the burn department. Ask one to come over. Then, take a piece of skin of 1 square centimeter from his body and use this induction formula for in vitro amplification." , see if it can't expand the skin of normal quality."

"If the skin expansion goes well, we will strive to obtain a method for muscle expansion in the next step. It is easier to grow an organ using the genetic information of the cell itself than 3D printing an organ. Of course, if we have sufficient funds, don't give up 3D printing. The line, until the end, no one can know who is right."

Tang Shun met a bosom friend and talked eloquently.

"Complex organs, such as the heart, liver, and kidneys, require cultivation technology, while simple organs, such as cartilage, bone, and tendon, have more advantages in 3D printing. It's like gasoline cars and diesel cars. Both routes have their own advantages and disadvantages. , Big trucks use diesel, cars use gasoline, the two are not contradictory, the two can coexist, not me without you.”

Song Zimo also agreed with Tang Shun's point of view:
"For example, cartilage printing is used in plastic surgery. It can precisely print any shape you want, but cultivation can't do it."

Tang Shun immediately said:
"Cultivation can actually be done. The introduction of plastic molds, but its timeliness is not as good as 3D printing, so the two routes can go hand in hand. At least in the short term, 3D printing is difficult to print complex organs."

"With you in charge of the stem cell laboratory, I feel at ease. Let's start with the small experiment of skin in vitro expansion. After the stem cell laboratory, you will be the master. You have the right to recruit people, apply for funds, and purchase equipment independently, and in terms of funds We are very sufficient, don't worry, Dr. Song, you take Dr. Tang to go through the entry procedures."

Yang Ping was very happy that his stem cell laboratory had finally found the right person.

After reading the A4 paper again, Tang Shun had studied stem cells for many years, and his intuition told him that this so-called small experiment is the most advanced technology in the world today.

The induced differentiation of cells is promoted to a spatial configuration, not scattered single cells.

Back then, after Maninstein found out the induction formula of skin in vitro amplification technology from experience, he had no way to grasp the principle behind it.

Later, the genius turned to the research of spinal cord injury and gave up the project.

PS: It's really helpless to stop updating for so long, and I apologize again!But as long as I have time, I will try my best to update it, eunuch-that is impossible.Let's count the votes and encourage them!
