Coming out of Ma Xiaochen's ward, Zhao Heng came to the bedside of the patient with "tree man disease".

Before arriving at the bed, Zhao Heng motioned to Tian Zhen to disassemble the gauze on the patient's legs and take a look at the recovery.

For this patient with "tree human disease", Zhao Heng used a new method of transplanting epithelial stem cells for him, and in general, the previous recovery has been very good.

Moreover, epithelial stem cell transplantation has a wide range of applications, and many skin defects caused by trauma, such as burns, burns, and chemical injuries, can be transplanted with epithelial stem cells.

After the gauze was opened, Zhao Heng saw that fresh granulation tissue had been seen on the patient's legs, which indicated that the transplantation effect was very good, and the epithelial stem cells had been divided into skin tissue cells in the skin of the patient's legs.

"The recovery is good, and after another batch of transplants, you can basically go back to your local hospital for further treatment later."

Zhao Heng looked at it, was very satisfied, and said to the patient's uncle.

"Thank you, thank you, doctor."

The patient's uncle said very gratefully, he had this strange disease, and after repeated torture of seven surgeries, he finally saw the light of day.

Seeing the thirteen or fourteen trainees, training and interns who followed him in, Zhao Heng suddenly thought that as the deputy director and senior doctor, it should be the time to ask questions, and then according to the answers of these people, he explained it again to deepen their impression.

Thinking of this, Zhao Heng looked at this group of people and said slowly: "For the treatment of this patient, induced pluripotent epithelial stem cells were used, who can say what are the four key genes that are finally identified as transcription factors in the cultivation of induced pluripotent epithelial stem cells?" ”

Zhao Heng decided to ask a relatively simple question first, of course, this was just a very simple question that Zhao Heng saw.

However, as soon as the question was asked, the scene fell into silence, especially the trainees, regular training and interns, all of whom lowered their heads and pondered hard, but they couldn't think of Zhao Heng's question.

It is really the knowledge of induced multifunctional epithelial stem cell cultivation, which is too cutting-edge and high-end!

Don't talk about intern doctors, let's just say that doctors in advanced training and regular training are still in the stage of cognition, identification and diagnosis of common diseases and frequent diseases.

For the cultivation of induced pluripotent epithelial stem cells, a technology in the field of biological genetic engineering, it is too high-end for doctors who are just getting started.

The atmosphere of silence continues.

Zhao Heng didn't expect this to be the case at all, in his view, the application of stem cells has now been relatively small-scale, as a doctor, he should have a certain understanding of this.

Compared with the preparation of nanomaterials, as well as nanotherapy, as well as the study of brain function, the restoration of consciousness, and the knowledge of stem cells, in Zhao Heng's current level, it is relatively simple.

Why didn't the Manchu civil and military say a word?!

Zhao Heng's eyes swept around the trainees, training and interns, and everywhere his eyes went, he lowered his head, for fear that he would answer by name.

There are so many people, if you can answer it, you will naturally show your face, but if you can't answer it, this is a disadvantage for the teacher.

Everyone is just getting started at the center, and no one wants to start with a hanging.

As for Liu Meng and Li Yang, there was naturally no problem with answering, and Zhao Heng didn't want to ask them in the first place.

Just when Zhao Heng felt a little disappointed, Ruan Liuzheng suddenly spoke: "Director, in the culture of induced multifunctional epithelial stem cells, there are 4 key genes that have been finally identified as transcription factors, namely OCT4, SOX2, KLF4 and C-Myc. ”

Hearing Ruan Liuzheng answer like this, Zhao Heng's brows stretched, there are still people who can answer, which shows that it is not his problem that is difficult, but that these people do not work.

"So tell me more about the significant advantages of this induced pluripotential epithelial stem cell (iPSC) in terms of cells and genes, especially in the treatment of skin diseases?"

Zhao Heng was very satisfied with Ruan Liuzheng's answer, and decided to ask again to see what kind of level her level was.

If Ruan Liuzheng's good personality left a little impression on him before, then now, this Ruan Liuzheng is still very good professionally, just look at what level she is.

Hearing Zhao Heng's question, the doctors at the scene, except for Li Yang and Liu Meng, were all stunned, and some people stared at Ruan Liuzheng tightly.

This seems to say, can you still answer it?

Ruan Liuzheng is in the ward, it does cause a lot of commotion, of course, the male doctor likes this kind of girl with good looks and temperament and good personality, as for the female doctor, for Ruan Liuzheng, naturally there is a feeling of same-sex rejection.

After all, as soon as Ruan Liuzheng came, there was a senior doctor who was a familiar senior sister, and this advantage was simply a dimensionality reduction blow to others who had nothing to do with it.

After Zhao Heng asked, he looked at Ruan Liuzheng's eyes, and he was also scrutinizing, if the question just now was what Zhao Heng thought was simple, then this question was a bit difficult.

After all, induced pluripotent epithelial stem cells, that is, iPSCs, are very little known by ordinary doctors, let alone can say the specific use.

Hearing Zhao Heng's question, Ruan Liuzheng was not in a hurry, he thought calmly, and the spark of wisdom began to flash, saying that it was a flash, but it was better to say that Liu Meng had made her make sufficient preparations before, and now it came in handy.

However, maybe Liu Meng didn't expect that Ruan Liuzheng was so well prepared and so deep.

"The Director, patient-derived iPSCs, has significant advantages in both cell and gene therapy prescriptions. The use of iPSCs to treat skin diseases first requires effective differentiation into the main cells of the skin, namely keratinocytes and fibroblasts. ”

"These cells can be used to study and treat wound healing and other degenerative skin diseases, and can also provide new tissue engineering therapies for hair loss."

Ruan Liuzheng talked eloquently, and it was clear that she really understood these very awkward knowledge, rather than simply rote memorization.

As soon as she said this, the eyes of several doctors who had advanced training and regular training widened!

Everyone is on the same starting line, and if everyone can't answer, that's normal.

But as soon as Ruan Liuzheng answered like this, it showed that other people's knowledge reserves were insufficient.

"Dr. Ruan, is there anything else?"

Hearing Ruan Liuzheng's answer, Zhao Heng was very satisfied, and he continued to ask, he wanted to see if Ruan Liuzheng could come up with a little more in-depth content.

As soon as Zhao Heng asked, several doctors of further study and training looked at Ruan Liuzheng again.

These people thought to themselves, you finally can't answer now, right?

If you can answer, I will roll in the ice and snow at 360 degrees!

Ruan Liuzheng fell into deep thought for a moment.

"It's okay, it's normal not to think of it, you can understand this level, it's already okay."

Zhao Heng saw that Ruan Liuzheng didn't answer again, so he said slowly.

"Director, iPSC should also be used as an emerging targeted gene therapy tool for the treatment of hereditary diseases, and it can also be applied to regenerative medicine."

】

To Zhao Heng's surprise, Ruan Liuzheng pondered for a moment, and then said in a calm and firm tone.

"Very good, Dr. Ruan, you have said it very comprehensively, and you can see that you have worked hard."

Zhao Heng said to Ruan Liuzheng with great satisfaction.

"Everyone has to learn from Dr. Nguyen."

After a pause, Zhao Heng said to the doctors for further study and training.

As soon as Zhao Heng's words came out, the doctors all looked at Ruan Liuzheng with different eyes, Liu Meng was naturally very pleased to have a good relationship with Ruan Liuzheng like this, and the male doctors had a better impression of Ruan Liuzheng deepened, as for the other female doctors, the eyes that looked at Ruan Liuzheng were not so friendly.

After checking the room, I went back to the office.

When everyone was about to enter the office, Zhao Heng, who was supposed to go back to the deputy director's office, suddenly received a consultation from the Department of Brain Surgery.

This kind of consultation, Zhao Heng has always gone alone before, but Ruan Liuzheng's unexpectedly good performance just now really impressed him.

"Dr. Ruan, you come with me for a consultation."

Zhao Heng stopped Ruan Liuzheng, who was about to enter the doctor's office with Liu Meng.

Zhao Heng said this, and everyone who was going to enter the office looked at Ruan Liuzheng.

The eyes of envy and jealousy are even more obvious.

When Zhao Heng held a welcome meeting before, he made it clear that he would not bring students.

But today, Ruan Liuzheng behaved, and Zhao Heng took her directly to the consultation, which was to give her a chance.

This opportunity is simply too rare for these trainees, trainees and interns.

Ignoring Zhao Heng's age, everyone who came here knew that Zhao Heng's level was recognized as high in the entire hospital, and the directors of several departments were full of praise when they mentioned Zhao Heng, basically when Zhao Heng was regarded as a person of the same status and identity.

So now, in the entire Oriental Hospital, no one will look down on Zhao Heng because of his youth, after all, his brilliant achievements are in front of him.

Let's just say that among the trainees, trainees and interns who come to the center, who doesn't want to learn from Zhao Heng?

Learning to use one hand and two hands is simply inexhaustible.

It can be said that in the eyes of everyone, Zhao Heng is simply a treasure all over his body now.

"Good.

Good! Director! ”

Ruan Liuzheng was cued by Zhao Heng like this, and some did not react, but he was immediately overjoyed and said quickly.

It's still useful to prepare!

Thinking of this, Ruan Liuzheng couldn't help but glance at Liu Meng.

And Liu Meng also gave Ruan Liuzheng a smile.

Although Ruan Liuzheng can answer it, it is because he has prepared well, and his knowledge is indeed reserved, and he has put in a lot of effort, otherwise he would not be able to answer.

If others can't get used to it, who made you not work hard yourself?!

Therefore, Zhao Heng likes this kind of caring person, as long as he really works hard, he has this basic attitude.

Prepare well before ward rounds, which is what junior doctors should do, preparation-question-professor, this process is part of the doctor's learning system, in order to deepen learning and memory, and then understand and apply.

Following behind Zhao Heng, Ruan Liuzheng was a little excited, after all, there were more than ten people in this group of advanced studies, training and interns, and she was the first person who could follow Zhao Heng to the consultation, this feeling of being valued and noticed was still very good.

It's a person, and they all like to be valued.

Especially medical students, in fact, they are generally more serious, after all, with the study of medical majors, if you are not a little serious, you may not be able to get a graduation certificate.

Some people will ask, how tiring is studying medicine?

The answer is very tired, very tired!

Let's just say that when Zhao Heng was studying in the School of Liberal Arts, the dormitory of the main department of the medical school was uninterrupted 24 hours a day, the bathhouse was open for hot water 24 hours a day, and the study room was open 24 hours a day.

And in the senior year, the days of interning during the day, coming back at night to stay up late to revise for exams, and one exam a week are simply devils.

When it comes to exam season, I study all night until 4:00 in the morning, go back to the dormitory and sleep for two hours, and then get up to continue studying.

Zhao Heng's roommate, a brother, also complained, "I want to go to bed before 23:00 in the evening for the entire senior year of high school, and before the college entrance examination, I didn't work so hard, why has it fallen to this point now?!" ”

8-11 years of medical training program, which one is not tired of scientific research and clinical practice?

Let's just say that the resident doctors of the Department of Surgery of Dongfang Hospital had 9 surgeries a day, and they only got off the stage at 4:00 in the morning, and they slept in the hospital, causing ward rounds at 7:00 to be correct, and they had to be on duty every week at night and on holidays, and during this period, they were thousands of dollars a month.

It can be said that it is purely for love!

"Director, what kind of patients are we going to consult with the brain?"

Ruan Liuzheng asked curiously as he walked behind Zhao Heng.

Before coming to the center, she had heard that Zhao Heng's patients were treated with incurable diseases, even the world-famous Mayo Clinic.

In the eyes of the young doctor, Zhao Heng has now become a legend!

"It's a patient in a long-term coma."

Zhao Heng said briefly.

This Ruan Liuzheng has a very good personality, and when I look at it today, his professional attitude and knowledge are also online, such a person, just like Liu Meng, is still worth paying a little attention to.

Zhao Heng is not a god, and it is impossible for one person to do everything, so Zhao Heng has already put the matter of cultivating assistants on the agenda.

In addition, this Ruan Liuzheng has a good appearance and temperament, and he is born with a sweet smiling face, which can also be eye-catching, why not do it!

"The director of the Department of Brain Surgery asked the director to consult in the past to carry out wakefulness stimulation treatment?"

Ruan Liuzheng reacted quickly, wasn't Zhao Heng famous for waking up my country's famous skier Sun Xinxin, who had been in a coma for three months after waking up with a serious injury, and even the Mayo clinic had no way to do it?

"It should be, you'll know when you go."

Zhao Heng nodded.

In terms of promoting awakening, Zhao Heng's current level can be said to be the top in China and even in the world, transplanting neural stem cells to restore brain function and promote awakening, which has not happened before Zhao Heng, and it can be said that this is the only one.

However, when he thought of awakening, in addition to the physical means of stem cell transplantation, Zhao Heng also thought of psychotherapy.

As for psychotherapy, among the people Zhao Heng knew, it was Gao Qilan who was the most powerful.

Zhao Heng has already picked up and fused the perfect level of psychological counseling technology from Gao Qilan's side, and he is still waiting for Gao Qilan's side to prepare for deep hypnosis and go to observe!

When the time comes, once you pick up the master-level hypnosis technique, it will be very useful!
