Three days later.

Nine a.m.

Sterile puncture room in the Oriental Hospital.

With Zhao Heng's help, the cultivation speed of neural stem cells has been greatly accelerated.

At seven o'clock in the morning, Zhao Heng and Gao Jun went to Yenching University to retrieve the first batch of neural stem cells that had been cultivated.

As soon as he got it back, Zhao Heng immediately prepared for Sun Xinxin, and now, it is to be transplanted through the transcerebral crest route.

Among all the stem cell transplantation pathways, the brain crest fluid route is the most direct and the most effective, the core of this transplantation method is stem cell homing and brain crest fluid circulation, that is, through lumbar puncture, exogenous stem cells are injected into the cerebral ventricles and cerebral cisterns, and stem cells enter the damaged brain tissue through the cerebral crest fluid circulation.

In the puncture room, Zhao Heng and Tian were really preparing for the puncture.

Outside the puncture room, separated by thick transparent glass, only Gao Jun and Sun Xinxin's mother were there at the moment.

Although Sun Xinxin, a patient, is more important, it does not mean that everyone was there when she was treated.

In Dongfang Hospital, there is more than one patient like Sun Xinxin.

"Director Gao, after Xinxin has undergone this treatment, she will definitely be able to wake up, right?"

Sun Xinxin's mother looked at her daughter lying in the puncture room with infinite love, and then asked Gao Jun hopefully.

"There is a lot of hope, this time, Professor Li Hongwei from the School of Life Sciences of Yenching University has participated, and it can be said that there is no such strong medical force in the whole country."

Gao Jun said loudly.

"Well, well, thank you so much, Director Gao."

Sun Xinxin's mother nodded again and again, in order to treat her daughter, people invited all the professors from Yenching University, what else did she have to say?

Compared to the previous Mayo Clinic, she has never even seen the head of the department, and she has always been an attending doctor to handle everything, such a difference is too obvious.

This can only show that only your own cub is really hurt!

"Don't thank me, the reason why Professor Li Hongwei of Yenching University was able to participate in the treatment was invited by Dr. Zhao."

At this time, Gao Jun naturally did not forget to mention Zhao Heng.

"Well, well, it's her luck that Shin Shin was able to meet Dr. Zhao."

Sun Xinxin's mother nodded again and again.

She said this sincerely.

With the experience of visiting the Mayo Clinic, compared with the current one, Sun Xinxin's mother knows that only here is she and her daughter truly her own people.

What's more, since her daughter was transferred here, she has seen Zhao Heng's actions.

Inside the puncture chamber.

Tian Zhen looked at the tube of injections in Zhao Heng's hand with some curiosity, which contained cultivated neural stem cells.

"Dr. Zhao, is this the neural stem cell cultivated by Professor Li Hongwei of the School of Life Sciences of Yenching University?"

Tian Zhen asked with some curiosity.

"Hmm."

Zhao Heng nodded.

"This is the only one of its kind in the country."

Tian Zhen said with some sighs.

In Zhao Heng, impossible things can always happen.

Just before, the entire East Hospital, who could have imagined that just because Sun Xinxin was going to do stem cell therapy, Zhao Heng went to Professor Li Hongwei from the School of Life Sciences of Yenching University.

"Doctor Zhao, how did you get Professor Li Hongwei to be recruited?"

Tian Zhen asked very curiously.

Her doubts are also something that everyone in the hospital has always been unable to understand.

Even with Gao Jun's background, it is not so easy to invite Professor Li Hongwei.

Not to mention Zhao Heng, who was just a grassroots white body before.

"I just went to listen to the professor's open class, and then after the class, I discussed it, and the professor agreed."

Zhao Heng said very calmly.

This is also true, but if someone else goes, it will definitely not be invited.

"It's as simple as that?"

Tian Zhen said with an incredible expression.

How can a top professor like Li Hongwei in the country be invited so easily?

"Well, it's as simple as that."

Zhao Heng nodded.

"Okay.

”

Tian Zhen looked at Zhao Heng with a serious face, not like a joke, and could only nod.

If a miracle happens to a person once in a while, everyone may be very excited, but if it happens too much, just like Tian Zhen now, then it will not be so exciting and accustomed to it.

"Doctor Zhao, the disinfectant towel is ready."

Tian Zhen's movements were very swift and he was quickly prepared.

"Well, let's get started."

Zhao Heng nodded.

The next lumbar puncture was not difficult for Zhao Heng, so the process went smoothly.

Half an hour later, the first batch of neural stem cells jointly cultivated by Professor Li Hongwei and Zhao Heng have entered the damaged brain tissue through the cerebral crest fluid circulation.

There are six days left before the two-week deadline.

After completing the operation, Zhao Heng looked at Sun Xinxin, who was lying on the operating table, still with his eyes closed and his face pale, and thought.

Wait another six days, and everything will be clear.

Next, Sun Xinxin, who had finished the treatment, was sent back to the ward.

As soon as Zhao Heng came out, Sun Xinxin's mother said to Zhao Heng very gratefully: "Doctor Zhao, Xinxin's treatment is really troublesome for you." ”

"It's fine."

Zhao Heng waved his hand and said.

"Doctor Zhao, can Xinxin wake up this time?"

After expressing her gratitude, Sun Xinxin's mother asked Zhao Heng very nervously and tentatively.

From her daughter's injury to now, in more than three months, she has experienced too many times from hope to disappointment, so that now, she doesn't dare to have too much hope, for fear that she will be disappointed and unable to accept this huge psychological gap.

"Professor Li Hongwei's research on stem cell therapy is the best in the world, and if neural stem cells play a role and successfully repair brain tissue, then the possibility of waking up is very high."

Zhao Heng pondered for a moment and said.

As a doctor, you can't say 100% at any time.

However, he said this, which is already a very confident statement, and the reason why he mentioned Li Hongwei is because Li Hongwei's current reputation and academic status are indeed at the top level.

As for Zhao Heng, although he has a deep grasp of cell fate regulation, Professor Li Hongwei still has other advanced technologies, and these techniques, to be honest, Zhao Heng wants to learn them.

"Uh-huh."

Sun Xinxin's mother was very excited when she heard Zhao Heng's answer, and hope surged in her heart.

After receiving some affirmative answers from Zhao Heng, Sun Xinxin's mother was excited, and she went out to take care of her daughter in a hurry.

After Sun Xinxin's mother left, Gao Jun said to Zhao Heng with some sighs: "Xiao Zhao, if we can succeed this time, the fame of our center can be regarded as out." ”

"It's not easy."

Zhao Heng also said with some embarrassment.

It is not easy to start a career from scratch.

If he hadn't hung up, it would have been impossible to say that he had been on the line with Professor Li Hongwei.
