Next.

Eight twenty a.m.

Inside the changing room of the operating room.

At this time, the instrument nurses in the operating room were already changing their clothes and preparing to go to work, and Xu Manni was no exception.

Just as she was changing her clothes, Sun Li stood next to her, looked at Xu Manni, smiled and said to her, "Look at your appearance, you were very hi last night!" ”

"Looks like it's time for me to introduce you to a boyfriend, seeing how much you care about my love life all day.

”

Xu Manni glanced at Sun Li and said.

Of course she had a good time last night, although it felt a little weird at first, but once she got used to it, it still felt pretty good, and the most important thing was that there was a sense of freshness.

Of course, this is also because Xu Manni herself is studying medicine, and she works as an instrument nurse in a place like the operating room, so she is naturally more open.

Therefore, when it comes to falling in love, it is the most important thing to find someone who is compatible with you.

"Don't, if there is a doctor like yours, then I can still reluctantly accept it, forget the rest."

Sun Li waved her hand and strongly rejected Xu Manni's proposal to introduce her boyfriend.

She is living a good life by herself now, why should she be uncomfortable.

Like Zhao Heng, young, handsome, capable and promising, then Sun Li felt that she could still consider it.

As for the rest, at Sun Li's age in her early thirties, the introduction is not necessarily a strange person.

"If that's what you're asking for, it's still quite difficult."

Xu Manni said.

The reason why a thirty-year-old woman doesn't want to fall in love and get married is probably because she doesn't like all kinds of blind dates.

Thirty-year-old women don't like blind dates, and men don't like to go on blind dates with thirty-year-old women.

There is a problem that concerns a lot.

What is the experience of going on a blind date with an older leftover woman who is 30 years old or older? 》

One of the most praised answers is this:

The biggest feeling is that you are a licking dog licking grenades, licking it cold, no heat, no feedback, no fun, and if you are not careful, you will inexplicably lick and explode, blowing yourself up in the face.

Although it is a joke from netizens, to a large extent, it reflects the current situation of blind dates for women aged 30 or above.

This is the cold and brutal reality.

"Anyway, you should pay attention lately, I think some people are jealous that you are about to get pink eye."

Sun Li said again.

She and Xu Manni have been good friends for many years, so Xu Manni has found a good home, she will only be happy for her, but others are different.

If you want to say that hospitals have the most problems with each other, it must be the group of nurses.

If you think about it, you can also understand the feelings of other nurses when they look at Xu Manni, not to mention the beauty of Changmei, the family background is fine, and now she is running for the head nurse soon, and other nurses may not have such an opportunity in their lives.

And now, there is another reason for jealousy, that is, to find a perfect little boyfriend, just ask, whether it is a man or a woman, who doesn't like old cows to eat tender grass!

"Let them be jealous if they are jealous, and I won't lose a piece of meat or anything."

Xu Manni said disappreciatively.

From childhood to adulthood, she has been the object of envy and jealousy of the girls in her class.

Since she came to work in the operating room of the hospital, other nurses have also had a lot of opinions about her, consciously or unconsciously.

These are all very normal, hating others and hating oneself, this is the normal state of life.

"I think it's better for you to pay attention, now is a critical period for you to run for head nurse, don't let anything happen at this last trembling moment, then you will regret it for the rest of your life."

Sun Li reminded Xu Manni.

She and Xu Manni are good friends, if Xu Manni becomes the head nurse, her life will definitely be very good in the next 10 years, which can be regarded as a person who has ascended to heaven.

"yes, I see."

Xu Manni nodded, although it was already a matter of eighteen or nineteen years since she was elected as the head nurse, she still couldn't be too careless.

The other side.

Zhao Heng also arrived at the office, and soon, everyone arrived, and the morning meeting began.

"Today I am going to Professor Li Hongwei's experiment to prepare carbon nanotubes for the first time, and I will hand them over to you in the ward."

Zhao Heng said to Li Yang and Liu Meng.

The speed of developing siRNA colloidal beams is not so fast, so if you want to stabilize Ma Xiaochen's condition and buy time, you must first use carbon nanotubes to load drugs as the current treatment.

Although it cannot be completely cured, at least it can stabilize the condition, which is much better than any other glioma treatment methods at present.

"yes, okay."

Liu Meng and Li Yang nodded together, now that the ward is here, the two of them are almost familiar, so even if Zhao Heng is not there, the two of them can handle it.

After the morning meeting, Zhao Heng took Liu Meng and Li Yang to check the room together.

When he came to Ma Xiaochen's hospital bed, Zhao Heng saw that Liu Qing still came early, sitting on the side of the bed, or maybe he didn't go back at all last night.

"How are you feeling today?"

Zhao Heng asked Ma Xiaochen, who was lying on the hospital bed with a pale face and a not very good complexion.

To say that Ma Xiaochen can be said to be the richest second generation in China, but obviously his luck is not very good, when he was just about to become an adult and start his happy life, he got glioma, a very difficult malignant tumor.

It was his luck to be born in the richest family, but he was terminally ill, which shows that his luck in other aspects is not very good, so this fate is quite wonderful.

In other words, fate is fair to everyone.

Giving you something will always take away something else from you.

"It's just a headache, and I want to throw up."

Ma Xiaochen's face was pale, and he said in a weak tone.

In the advanced stage of malignant tumors, they are all like this, they can't eat, their digestion is not good, and the body's consumption depends on their own stored fat, and once it develops, it is extremely emaciated.

"Add a little antiemetic liquid today."

Zhao Heng turned his head and said to Liu Meng.

"Dr. Zhao, when will you start nanotherapy?"

Liu Qing stood up and said with some eagerness.

She understands that her son is now in a race against death, and now every extra minute he lives is earned.

"This afternoon, I will go to the laboratory of Professor Li Hongwei of Yenching University to prepare the first batch of carbon nanotubes for stabilizing the disease, and the research and development of siRNA colloidal bundles is underway."

"Don't worry."

Zhao Heng explained, comforted Liu Qing and said.

He could understand Liu Qing's anxious mood now.

"Well, thank you, Dr. Zhao."

Liu Qing nodded, she knew that she was in a hurry, but she couldn't help but be in a hurry.

At her level, marriage is actually nothing, and what she cares about most now is a son.

After checking the room, Zhao Heng came out of the hospital and came to the No. 1 laboratory of Professor Li Hongwei of Yenching University.

When I arrived at the laboratory, it was exactly nine o'clock, and Professor Li Hongwei was about to start his day's work.

In the laboratory.

Zhao Heng and Professor Li Hongwei stood in front of the reactor together, at this time, the first batch of raw materials had been put into the reactor, and the next step was a very subtle real-time adjustment.

"Professor, why are there so many more ingredients this time?"

Zhao Heng saw that the raw materials in the reactor were obviously over, and he couldn't help but ask with some doubts.

"It's country H, and this batch should be used as a sample."

Professor Li Hongwei said briefly.

If Professor Li Hongwei is not easy now, leading this large national laboratory, and the results produced by this laboratory can not produce economic benefits so quickly, so his pressure is still very great.

In particular, the pressure from the shortage of funds has always been the biggest problem facing Professor Li Hongwei.

But now, an investment of up to one billion yuan from Jianteng Group has greatly alleviated the problem of Professor Li Hongwei's shortage of R&D funds, and it can be said that in the next five to ten years, this laboratory will not lack R&D funds.

"Professor, can I ask, what did you change from country H this time?"

Zhao Heng looked at Li Hongwei and finally couldn't help asking.

As I said before, this time country H wants to get the preparation method of nano preparations, but it will bleed heavily, but what can be exchanged for something from there, Zhao Heng is still very curious about this.

"It's some of the technologies for semiconductors and graphene."

Li Hongwei said briefly.

For Zhao Heng, he has nothing to hide, after all, this time Zhao Heng can be said to have done a big thing, and he is very satisfied with Zhao Heng in all aspects, up and down.

This is the reward for Zhao Heng, that is, the business card that Gao Jun gave to Zhao Heng before.

"Well, this is what is worth a lot of money over there in country H, and the rest is so-so."

Zhao Heng nodded, semiconductors and graphene are indeed the strengths of country H, even if they can only be changed to a little bit, it can greatly solve the problem of "stuck neck" in these fields.

"That's right, it's technology that's the most valuable thing right now."

Li Hongwei nodded.

"Xiao Zhao, what do you think about the research and development of siRNA colloidal beams?"

After a pause, Li Hongwei asked again.

"With the current conditions, Professor, I tend to use free radical polymerization to prepare siRNA colloidal bundles."

Zhao Heng thought for a while and said.

"Well, tell me more about it."

Hearing Zhao Heng's words, Li Hongwei nodded and said.

"Professor, we know that siRNA is negatively charged, so we can first prepare a guanidinylation reagent containing acrylic bonds, and then adsorb it with siRNA in advance, so that free radical polymerization can occur on the surface of siRNA."

"Next, in the system, GSH-sensitive disulfide bonds and the acrylate structure of PEG-NHS can be introduced, and then APS and Temed can be added to initiate radical polymerization."

In this way, the prepared siRNA colloidal bundle can carry drug molecules and endocytosis into tumor cells through cerebral vascular endothelial cells and LRP-1 receptors that are highly expressed on the tumor surface. Under the action of high concentration of GSH in cells, siRNA can be rapidly released in the cytoplasm, and then achieve the goal of complete treatment of glioma. ”

Zhao Heng said in an orderly manner, in the process of preparing sirna, Zhao Heng wrote several large pages, and now he just said the basic process in a high degree of generalization.

"Well, Xiao Zhao, what you said is already perfect, just like what I thought."

Hearing such a highly generalized and organized statement, Li Hongwei looked at Zhao Heng with great appreciation, and his joy was beyond words.

Li Hongwei was worried before, because in the field of scientific research, now it is supported by old scientists like him in their 50s to 60s, which inevitably feels a bit like there is no successor.

After teaching at Yenching University for so many years, Li Hongwei has not seen a genius, whether it is an applied genius or a theoretical genius, it is often seen in Yenching University, the highest university.

But the best of these geniuses, without exception, did not choose scientific research that is slow to produce results and may take ten or twenty years to produce results.

Many people, the initial goal, is to study finance and management, and immediately after graduation, enter the investment bank, with a glamorous job, high income, and quick results, which is the common idea of young geniuses now.

What makes Li Hongwei most sad is that the year before last, a very promising doctoral student under him did not choose to engage in scientific research after getting a doctorate, but used this diploma to go to a key middle school in North City to find a job.

He was optimistic about the doctor, but did not choose scientific research, but chose to be a biology teacher in a middle school, which made Li Hongwei sad for a long time.

Of course, everyone has their own choice, but for everyone who studies for a doctorate at Yenching University, the country has to invest a lot of resources, and the degree is piled up with resources.

In other words, if you want to choose a biology teacher for middle school, you should not be studying for a PhD in the first place, and you don't even need a graduate diploma.

Letting a doctor of biology teach in a middle school is a huge waste of national educational resources!

"However, the free radical polymerization method is very unstable, we can wrap a layer of polymer on the surface of siRNA, and then add an angiopep-2 peptide containing amino groups for amidation reaction, so that the stability of the reaction will be greatly enhanced."

Li Hongwei thought for a moment and added.

"Well, this does greatly enhance the stability of the reaction."

Zhao Heng nodded, although Professor Li Hongwei's experience and knowledge have basically been picked up by Zhao Heng, but this fusion and application still needs some time to slowly run in.

For now, it is still Li Hongwei's genuine version, which is more thoughtful than Zhao Heng's pirated version, in terms of knowledge, the two can be said to be about the same, but obviously Li Hongwei is more skilled and handy in applying knowledge, which takes time to accumulate slowly.

"Xiao Zhao, I heard that you are studying in graduate school with Huang Lao?"

Li Hongwei looked at Zhao Heng and suddenly asked.

"Well, it's a master's and doctor's degree in anesthesiology."

Zhao Heng nodded.

"Since you are studying in graduate school, it is better to come to me to study one, I also have a place for master's and doctoral studies here."

Li Hongwei said.

This is something he has been thinking about for a long time, for a genius like Zhao Heng, Li Hongwei feels that it should be cultivated well, his talent should be used in scientific research, and he should study projects that can benefit more people.
