Half past eleven.

In front of Ma Xiaochen's hospital bed in the ward.

At this moment, Zhao Heng and Liu Ziang were waiting for Professor Li Hongwei's assistant Wei Jinghao to come over with this batch of nano-prepared carbon nanotubes.

I don't know why, I said that I came at eleven o'clock, but now it's half past eleven, and Wei Jinghao hasn't come yet.

This time, the use of nano preparations to treat brain tumors is also a good inspiration for Liu Ziang, so Liu Ziang also has to participate in the whole process, and he will continue to pay attention to Ma Xiaochen's situation in the future.

Among all brain tumors, glioma is a very headache for brain doctors, not only the risk of surgery is extremely high, but also the results of other treatments are not very good.

"Doctor Zhao, why is it eleven o'clock and you haven't come yet?"

Liu Qing stood opposite Zhao Heng and Liu Ziang, and said with some concern.

Regarding her son Ma Xiaochen's condition, Zhao Heng has repeatedly told her, and she also knows that this time the nano treatment is to alleviate the condition and develop the nano material siRNA colloidal beam for the final cure.

Therefore, although it was only half an hour late, Liu Qing was still worried.

"There may be a traffic jam, don't worry, it won't affect you for half an hour."

Zhao Heng said comforting Liu Qing.

For the treatment of tumors, the effect is not measured in days, at least in weeks, so that obvious results can be seen.

"Yes, Ms. Liu, the treatment of tumors is based on the surrounding units, so half an hour has no effect at all."

Liu Ziang also continued.

Hearing the two doctors say this, Liu Qing's anxious mood also calmed down a little, but she was still very worried in her heart.

Because Zhao Heng told her that the carbon nanotubes used in this nano treatment were made in a hurry, and they also had to be loaded with drugs, so if there was an accident this time, then it would take at least four or five days to make it next time.

These four or five days, for the advanced stage of the tumor, it is basically a small course of disease, and it will definitely delay the disease.

Thinking of this, Liu Qing couldn't help but regret in his heart, he had already known, so he sent the company's security team to the laboratory to pick up this batch of materials.

Next time, be sure to use the group's security team to pick it up.

Liu Qing said secretly in his heart.

With your own security team, you can report the progress in real time, unlike now, you don't know anything, and the wait is worrying.

"Would you like to ask what's going on in the lab?"

Liu Ziang whispered beside Zhao Heng.

In fact, several members of the hospital committee had to come to watch, but he told the dean that there were many people who came, which affected the scene, so he was the only one.

The treatment of the richest man's son should have been very big, but Liu Qing also considered that there were too many people, and it also had an impact on the attending doctor Zhao Heng.

Just as Zhao Heng was about to answer, Wei Jinghao walked in sweating profusely carrying a silver-white metal box with a biometric logo on the box.

"Sorry, there's a traffic jam on the road."

Wei Jinghao saw that everyone was staring at him, and hurriedly explained.

"It's good to be here."

Zhao Heng didn't say anything, and took the metal box from Wei Jinghao's hand.

"Let's go to the operating room."

After a pause, Zhao Heng said to Liu Ziang and Tian Zhen, who was standing on the side and had been waiting for a long time.

"Okay."

Tian Zhen nodded.

"Ms. Liu, you just stay here and wait, this operation is not big, it will be soon."

Zhao Heng saw that Liu Qing was going to go with him, and couldn't help but say to her.

To do nano treatment, the use of laminar flow sterile operating room must be used, and if one more person enters, there will be more risk of infection in the injection of nano preparations, so this time, only Zhao Heng, Liu Ziang and Tian Zhen will go in.

】

As for teaching or something, that's even more unnecessary.

The most critical part, and the most valuable part, of nanotherapy is the treatment of nanoagents.

As for the actual part of nanotherapy, it is just to inject nano preparations into the patient's body, and this process is that the environment and operation are strict and precise, and there is nothing too technical.

"Okay."

Liu Qing glanced at Zhao Heng deeply and nodded.

This glance contains hope and a kind of trust in it.

Fifteen minutes later.

Laminar flow in a sterile operating room.

If modern medicine is still quite dependent on science and technology, it is said that this laminar flow sterile operating room uses air cleaning technology to control microbial pollution sources to different degrees, so as to achieve the requirements of air cleanliness in the controlled space environment suitable for all kinds of surgery.

Moreover, it can provide suitable temperature and humidity to create a fresh, clean, comfortable and low bacterial count surgical space environment, so that the patient's tissue is damaged as little as possible during the operation, and greatly reduce the secondary infection rate of patients and medical staff, especially intracranial surgery and burn surgery, to ensure that patients can recover faster and better after surgery.

This laminar flow sterile operating room is 100 levels, 100 level laminar flow sterile operating room requirements, per cubic meter of indoor air, the number of colonies contained in less than 1, generally we are in the usual breathing air, if you know the content of colonies per cubic meter, you will know what kind of cleanliness this is.

Compared with ordinary clean operating rooms, its purification standards are more than 200 times higher.

The most advanced in the laminar flow operating room is the 100-level laminar flow operating room, which is equivalent to the standard of the space laboratory.

In order to maintain such a high standard of air cleanliness, the purification measures required must also be very strict. Under normal circumstances, the 10,000-level laminar flow operating room should maintain air ventilation at least 600 times per hour, and be equipped with a high-efficiency air filter to filter out 99% of the dust and most of the bacteria in the air. Then carry out strict air disinfection and purification, as well as thermal insulation and sound insulation effects.

Therefore, the construction of this operating room alone requires extremely high technical skills.

Not to mention the carbon nanotubes to be used later, it is the pinnacle and cutting-edge field of modern science and technology.

Ma Xiaochen, who was lying on the sterile operating table at the moment, had been lightly anesthetized and was gradually falling asleep at the moment.

And Zhao Heng and Liu Ziang are waiting for the anesthesia to take full effect.

"Junior brother, I didn't expect that you, a doctor in anesthesiology, have gone further than me in the treatment of brain tumors."

Liu Ziang said with a sigh.

He watched Zhao Heng get up step by step, and the process was unbelievably fast.

"Brain is the pearl of medicine, but also the most difficult, with our current progress, it can be said that it is only a small step."

Zhao Heng shook his head slightly and said, it is precisely because he has gone farther than most doctors that he knows that at present, he has only taken such a small step in the in-depth development of medicine.

Let's just say that the brain, the most extraordinary thing in the universe, modern science research on the brain is still in its infancy.

Even if you travel every inch of outer space, you may not find anything more magical, more complex, and more powerful than the two-and-a-half-pound soft sponge-like thing in a human skull.

The biggest paradox about the brain is that everything you know about the world comes from an organ that has never seen it with your own eyes.

The brain exists in silence and darkness, like a prisoner in a dungeon.

It has no pain receptors, no sensation in the truest sense of the word.

It has never felt the warmth of the sun, or the gentle breeze.

To the brain, the world is just an electrical impulse, like a series of Morse code taps.

From neutral information, the brain creates a vibrant, three-dimensional, and sensually engaging universe for humans.

Your brain is you.

Everything else is just pipes and brackets.

"I can't say that, in fact, brain science is indeed advancing by leaps and bounds, and the basic principles of neural operation are already very clear, and how various neurotransmitters and nerve signals are transmitted are also basically studied. At present, the hardest part of brain research is the study of consciousness and cognition. ”

Liu Ziang said.

As the top brain expert in the country, his words are still very valuable for reference.

"Well, we now know which part of the brain is mainly functioning, which parts of the brain are working together when processing information from the outside world, the role of hormonal neurotransmitters, and the chemical effects of certain processing information."

"But the deepest, biggest confusion is how human consciousness is generated, what is the molecular basis of consciousness, and what are the principles and chemical processes that sustain consciousness."

Zhao Heng also said with a sigh.

"Yes, if consciousness can be expressed through matter, then can matter control the generation of consciousness? If so, does it mean that the desired consciousness can be artificially made? If it can be artificially made, then what are we? There is also the nature of emotions in the brain. ”

"These problems, the current exploration progress of modern brain medicine, is too slow."

Liu Ziang continued.

What he said is to be understood more simply, for example, how the brain is active when human beings have strong beliefs, whether certain hormones and neurotransmitters are secreted, or whether there are any special changes in brain tissue.

If we can correspond these material changes to the generation of beliefs, then can it be said that scientists can artificially create beliefs?

Maybe this is the prototype and principle of the Thought Seal?

Of course, the thought seal or something, I'm afraid it is allowed to be studied.

If you really want someone to study it, it can only be said that it is very punishing!

"Interfering with consciousness through material means or something, even if someone proposes this kind of research, it is not allowed to be studied, so let's not think so far."

Zhao Heng said.

"Doctor Zhao, Director Liu, the anesthesia is ready, and you can start."

When Zhao Heng and Liu Ziang were chatting enthusiastically, Tian Zhen looked at the life monitor, heart rate, breathing and blood pressure, as well as carbon dioxide content, all reached the standard for anesthesia completion, so he said to the two.

"Well, senior, let's get started."

Hearing Tian Zhen's words, Zhao Heng's thoughts were pulled back, and he nodded and said to Liu Ziang.

"Okay."

Liu Ziang also nodded.

The treatment route of this nanomedicine mainly includes three steps: the first step is intravenous injection of nanoparticles and enrichment into the tumor site; The second step is to use imaging guidance and exogenous stimulation for precise treatment of tumors; The third step is the in vitro metabolism of nanomaterials.

Ordinary nanotherapy often only focuses on one of the links, without considering the other links.

And the treatment that Zhao Heng has to do now, each of these three links is very complete, which requires extremely high knowledge and very rich experience to do.

An hour later, Zhao Heng put down the instrument in his hand and let out a long sigh of relief.

Although he knew in advance that the risk of nanosurgical treatment this time was very low, Zhao Heng was still very happy that it was really completed.

Next, we are waiting to observe the indicators to know whether the nanotherapy has taken effect this time, and how effective it is.

"Junior brother, I still have a few glioma patients in the department, if the treatment effect is good this time, I think a few patients in the department can also try this nanotherapy."

Liu Ziang cooperated with Zhao Heng to complete the operation throughout the whole process, and it can be said that in the entire East Hospital, only Zhao Heng can let Liu Ziang cooperate with the operation in this way of being willing to be an assistant.

"Hmm."

Zhao Heng nodded, Liu Ziang's support for him, he felt it.

It can be said that with Liu Ziang's status in the industry, it is commendable to be able to be his assistant.

Not everyone can put down their big expert shelf and be an assistant to Zhao Heng, who is currently just a resident doctor.

Let's just say that other experts in Dongfang Hospital, maybe these majors agree with Zhao Heng's level, but they may not be willing to be Zhao Heng's assistant to cooperate with his operation.

"It's time to go back to the ward."

Zhao Heng said to Tian Zhen who was standing aside.

"Hmm."

Tian Zhen nodded.

After a while, Ma Xiaochen, who was lying on the transfer bed, was sent out of the operating room, and Zhao Heng and Liu Ziang also came out together.

Seeing his son lying on the transfer bed and being pushed out, Liu Qing, who had been waiting anxiously for a long time, hurriedly stepped forward and asked Zhao Heng, "Doctor Zhao, how is the operation?" ”

"It went well."

Zhao Heng said briefly.

"Doctor Zhao, how much of a difference can this surgery have?"

Liu Qing asked very eagerly.

"This depends on the indicators after three days, if the treatment phase is good, it can greatly alleviate the condition, transplant the growth of tumor cells, and support the development of siRNA colloidal tracts."

Zhao Heng said.

"That's good, that's good, trouble Dr. Zhao."

Liu Qing said continuously.

No matter how prominent she is and how staggering the wealth of the group she controls, at least for now, she is just a mother worried about her son's condition.

Coming out of the operating room, Zhao Heng returned to the office, and when he looked at the time, it was already one o'clock at noon.

When doctors are like this, they are too busy to eat, that's a lot.

Zhao Heng was not very hungry, so he took out some small bread from the desk drawer, and as soon as he ate two, Tian Zhen walked in and said to Zhao Heng: "Doctor Zhao, a patient has been sent over from the emergency department, let you go and see." ”

"Now?"

Zhao Heng was a little puzzled.

"Hmm."

Tian Zhen said.

"Okay."

Zhao Heng took a bite of the small bread in his hand and stood up.

As soon as he left the office, Zhao Heng heard a suppressed and painful roar from not far away.

Yes~

It sounds chilling, like a sound that can only be made in a horror movie.
