Chapter 151 Talent Peach Blossom!Encounter with Qiao Yiyi (subscription required)
The three chatted for a while, and Qian Dongyu asked:
"Yiyi, how's the topic of your thesis going? I didn't ask you to change it last time. Do you have a new direction?"

Director Ling Zhongyu closed his eyes and meditated. He didn't speak, but his ears were listening to Qiao Yiyi's answer.

In fact, my student is very individual and persistent. Last time, he proposed a research direction: exploring the preservation method of allogeneic tendon.

So far, the conventional preservation method is cryogenic freezing, which is complex and time-consuming, and the activity of the preserved tendon is low, which limits its application.

It is not that no one has thought about improving the preservation method, but they have not proposed the best solution. Therefore, because of this limitation, allogeneic tendon transplantation has not been promoted much.

As a graduate student, Qiao Yiyi came to explore such a subject, which was really too difficult, and there was no guarantee that she would be able to produce results in a short period of time.For her current stage, it is not a good subject.

Therefore, Deputy Director Qian Dongyu has been persuading her to give up this project that seems to have great potential, but actually has little hope.

Hearing Deputy Director Qian Dongyu's question, Qiao Yiyi obviously didn't want to answer, because she still wanted to give it a try.She always felt that there was a good way to solve this problem.

Even, there is still a glimmer of hope in her heart, whether it is possible to get some inspiration in the treatment center in Hecheng City.

Seeing Qiao Yiyi remain silent, Deputy Director Qian Dongyu also shook his head helplessly:
"Since you still don't give up, I will give you another period of time. However, after one month, if you still can't produce results, you must stop. We will set a new direction for you to open the topic. Yiyi, Director Ling and I It is impossible for you to find a suitable preservation method so easily in a short period of time.”

Qian Dongyu also thought that when he was young, he always felt pretentious and could become a star doctor who could solve the industry's problems. However, after constant trial and error, he understood that most people are mediocre.

The method of preserving the allograft tendon that Qiao Yiyi chose was such an almost impossible task.Moreover, there are no experts in such a remote field, so there are too few industry experiences that can be referred to.Undoubtedly added a lot of difficulty.

"I really don't want to die until I reach the Yellow River."

Director Ling Zhongyu closed his eyes, and sighed in his heart. This student of his was the one to be sure of, and he was too stubborn.It is an advantage and a disadvantage, and it is easy to go all the way to the dark.

The three of them did not continue this topic, but talked about the trip to the treatment center.

Deputy Director Qian Dongyu was driving the car, and saw that the navigation was about to arrive at the First City Hospital, which was more than an hour earlier than the time agreed with Director Wei, so he suggested:

"Director Ling, why don't we contact Director Wei to greet him with great fanfare, and go to visit quietly first to see the true face of the treatment center on weekdays."

For this suggestion, Ling Zhongyu thought it was good. After all, he participated in the special project of the treatment center before, and the most important thing was to take a fancy to Qin Lang.

He also wanted to know how the treatment center usually operates, and whether it is worth their hard work and preparation for today's exchange topic.

Qiao Yiyi also had a gleam in her eyes, and she was also planning to go to the laboratory of the treatment center to see if there was any research on allogeneic tendons, or if there were people of the same kind.

Really, Director Ling and Deputy Director Qian are always pouring cold water on her, she needs some support and a life-saving straw!
"This is the subject I am most interested in and most want to complete. I don't want to end it before it starts."

Soon, the three of them quietly drove the car under the burn and plastic surgery building.

Ling Zhongyu brought the team members to the treatment center. Compared with the last time, Director Ling came to visit, and it has improved a lot.

"Well, let's go directly to the operating room of the treatment center to see their usual operation level."

Ling Zhongyu and head nurse Zhao Qiufang were already familiar with each other, and they greeted Zhao Qiufang. They were originally a cooperative team, and exchanges and learning were normal.

Director Ling signaled not to disturb Director Wei and the other doctors, and went to the operating room to observe.

And Qiao Yiyi was still a graduate student, so she didn't have much interest in this kind of surgery, so she applied with Director Ling to visit the laboratory of the treatment center.

Ling Zhongyu naturally knew her student, and she still didn't give up, but she didn't force her, so she let her run into a wall.

How could the treatment center of the city's No. [-] Hospital be able to inspire her, a topic that even they had given up on in the Department of Hand Surgery of the Ninth People's Hospital Affiliated to Jiaotong University in Shanghai: "Then you should go and visit."

Originally, today is the expert exchange day, and learning from each other is a very reasonable thing.

When Ling Zhongyu and the others were divided into two groups, in the operating room of the treatment center, three operations were still arranged for Qin Fa this morning.

In the past week, Yang Yi and Yang Yue have basically mastered all of Qin Fa's operations, so this operation is their first performance without Qin Lang's checkpoint.

Except for Deputy Director Huang Kaihang in the outpatient clinic, You Daren and Peng Yun.

And very discerning, Cheng Yunfeng, who brought three small benches, was all there.

Cheng Yunfeng was very sensible, he handed over the bench to You Daren and Peng Yun.

Then I came to the corner and sat in a row with the anesthesiologist.

When Ling Zhongyu brought Qian Dongyu into the operating room, he was obviously stunned by the battle in front of him.

"Where is this expert doing a demonstration?"

Ling Zhongyu blinked, and looked at the operating room. Everyone was watching quietly, but they were too embarrassed to disturb, so they took Qian Dongyu to the edge.

As for Ling Zhongyu and Qian Dongyu coming in to observe, You Daren, Peng Yun and others are also used to it. After all, these days, there are too many doctors from Qin Fa who come to observe Qinlang.

Director Tian Hua came to watch every now and then.

Sitting on the bench, they also felt that it was too far-sighted for Qin Lang to put Cheng Yunfeng in the Qin Fa study team. He was really the best logistics leader. Snacks, men with fruit, women with milk tea.

As for the two newcomers, Cheng Yunfeng also started to observe, they didn't know each other.

Where did the wild doctor come from?
Cheng Yunfeng frowned slightly. According to his observation, Director Tian Hua would show up on time whenever Qin Lang was the chief swordsman. Once Qin Lang was over, he would quietly leave.

Therefore, Cheng Yunfeng has already prepared, and when Qin Lang is in charge, he will prepare an extra small bench, and Director Tian Hua's flattery must be done well.

As for the number of these two newcomers, and whether they need good service, it remains to be seen.

On the operating table, Yang Yi and Yang Yue have already started the first step of tendon repair.

Ling Zhongyu and Qian Dongyu understood at a glance that this was a very routine repair operation for a hand avulsion injury.

"Why do so many people come to observe and study an avulsion injury operation?"

Both Ling Zhongyu and Qian Dongyu began to observe in puzzlement.

"Huh? What kind of stitching method is this?"

Even though he was well-informed, Ling Zhongyu was a little confused for a while. According to his common sense, the best way to repair the tendon here should be the improved Kessler method.What kind of stitching did they use?

Deputy Director Qian Dongyu also didn't quite understand, and even felt that this was nonsense.

In fact, Yang Yi is not Qin Lang. Although she has mastered the half-knot locking tendon suture method, her suture level is still acceptable in front of Ling Zhongyu and Qian Dongyu.

Therefore, they did not feel the extraordinary and uniqueness of this suture method.

However, after all, the two of them came from afar to observe and study, they were very patient, and they also wanted to see what kind of tricks Yang Yi was going to do.

Soon, Yang Yi completed the suture repair of the tendon, which was much slower than the conventional modified Kessler method.

Qian Dongyu looked a little distracted, after all, at his speed, how could the tendon repair be so slow.With this messy stitching method and slow movements, Qian Dongyu suddenly had a thought in his heart, whether he had overestimated the level of the treatment center.

The modified pentagonal skin flap and finger repair by Qin Lang must have been just a coincidence. After all, the level of this treatment center is too poor. It takes a group of doctors to observe and learn from such a slow operation.

at the same time.

In the laboratory of the treatment center, Qin Lang is personally preparing the amniotic membrane for Yang Yi and Yang Yue.

The amniotic membrane was bluntly separated from the placenta under sterile conditions, and then washed repeatedly with PBS liquid, and then soaked in DPBS solution added with penicillin, streptomycin and amphotericin B for washing.

Then spread the amniotic membrane on the sterile PVDF membrane on the ultra-clean bench, cut it into a size of 3 cm×3 cm, put it into a petri dish and add DMEM medium (DMEM+penicillin+amphotericin B+glycerol), Then it was stored in a -80°C refrigerator for later use.

In fact, there are too many patients in the recent Qin method, so Qin Lang needs to prepare a lot of amniotic membranes in advance.

While preparing the amniotic membrane, Qin Lang also thought of the vitrification preservation method of the allogeneic tendon that he had recently obtained.

The low-temperature freezing method commonly used in clinical practice is complicated and time-consuming, and the activity of the preserved tendon is low.The preservation method obtained by Qin Lang is a brand-new method, which uses the 10 culture medium of dimethyl sulfoxide and propylene glycol, plus 1640% fetal calf serum (FCS) as the base solution, combined with a special recipe made.

After that, the high-concentration solution is rapidly cooled in one step, so that the tissue and solution directly enter the glass state, and no ice crystals are formed during the freezing process, which avoids conventional ice damage and freeze-thaw effects, and effectively preserves cell activity.

This is a brand-new preservation method of allograft tendon.

Qin Lang is also thinking about finding a suitable time to find a candidate in the treatment center to arrange the experiment of this preservation method and the presentation of the results of the thesis.

With this new preservation base solution and vitrification method, it will be a new world to be able to carry out the new field of tendon allograft transplantation in the treatment center, especially for patients with long distance and multiple tendon defects Treatment.

The potential of this brand-new subject is no less than that of "Qin Law", and Qin Lang plans to gradually promote it to later, vitrification cryopreservation of cells (offspring cells, embryos, embryonic stem cells, etc.), and can be extended Clinically, skin, cornea, nerves, blood vessels, heart valves, cartilage, kidneys, etc.

Of course, each different goal and the base fluid required need to be tested.

Just when Qin Lang was about to roll up his sleeves and do a big job again.

[Ding, the talent of the host: Peach blossom activation! 】

Qin Lang was a little dizzy when he heard the inexplicable system prompt, and then heard a timid and expectant voice outside the laboratory:

"Hello, brother, can I come in and visit, can I visit?"

Qin Lang turned his head, looked over, and saw Qiao Yiyi, who was 1.7 meters tall, thin and white, and whose appearance was comparable to Tang Yue's.

The girl shyly pushed the black-rimmed glasses with her white and slender hand, and also looked at Qin Lang who turned her head, a little pleasantly surprised and handsome.

Seeing Qin Lang turn his head, Qiao Yiyi added another sentence:
"I'm a doctor from the Hand Surgery Department of the Ninth People's Hospital Affiliated to Jiaotong University in Shanghai, who came to the city's No. [-] Hospital with Director Ling for an expert exchange day. My name is Qiao Yiyi."

"Brother, hello!"
