Siheyuan: Rebirth in a prosperous era, great doctors are sincere

drought.

A reduction in food production is inevitable.

Disaster year.

In addition to dealing with the food crisis, we also have to prevent various infectious diseases.

In order to reduce the burden of medical treatment for the people, the State Council issued the "Notice on Reducing the Ex-factory and Sales Prices of Penicillin and Streptomycin".

The prices of penicillin, streptomycin and even other antibiotics such as oxytetracycline and sulfonamides have all been reduced.

Take penicillin, for example.

Within one month after the notice was issued, the retail price dropped from five yuan per stick to three yuan per stick.

Ever since Li Ping'an traveled through time.

In just a few years.

The price of penicillin has dropped from hundreds of thousands of yuan per tube in the first set of RMB when it was imported from the Soviet Union to hundreds of thousands of yuan per tube in the domestic version, and now to three yuan per tube in the second set of RMB. The price has returned to normal compared to gold.

Li Ping'an witnessed the gradual drop in the price of penicillin, and also witnessed the rapid increase in national strength after the establishment of Guo Jia.

The price reduction of drugs this time is very large.

It is estimated that the total price reduction amount that year will be more than 100 million yuan, which will truly bring benefits to the people.

Hospitals at that time were not profit-oriented.

Although the price reduction of drugs has some impact on the Sixth Hospital, the impact is not significant.

For the Sixth Hospital.

Although the prices of drugs such as penicillin have dropped, the number of patients visiting hospitals has increased significantly.

The overall benefits have not decreased much.

After getting married, Yan Jiefang still lived with his parents.

Principal Zhang is still very trustworthy.

The Zhang family gave the Yan family a lot of rice and flour, and even gave them some eggs.

The meals of Mr. and Mrs. Yan Jiefang and Zhang Lan are pretty good. If the third aunt makes something delicious, she will try to prepare it for them.

The couple has a very high status in the Yan family.

Yan Bugui placed all his hopes of having a grandchild on his second son, and ignored his eldest son Yan Jiecheng and his wife, showing less and less concern for them.

Yan Jiecheng and his father were refused to borrow a bicycle several times.

Yan Bugui was very angry.

He has done enough to help his eldest son.

Which of Yan Jiecheng and Yu Li's jobs and the house they live in was not obtained by him?

Yu Li has been married into the Yan family for three years, but she has not even given birth to a child for Yan Jiecheng. Yan Bugui thinks there is no need to be too polite to Li or even to his eldest son.

You want to have status in front of me without giving me a grandson?

How can it be?

Yan Jiecheng and his wife felt the pressure.

Enormous pressure.

Taking advantage of the weekend, the two went to the Obstetrics and Gynecology Department of Union Hospital to see a doctor, wanting to see if there was anything wrong with them.

result.

After inspection, nothing was found wrong.

Although the couple had been married for three years without having any children, they were indeed in good health.

After detailed inquiry.

The doctor felt that Yan Jiecheng’s work would have some impact on fertility.

Yan Jiecheng often has to travel on business.

The couple were rarely together, so it was naturally not easy for Yu Li to get pregnant.

The doctor suggested that Yan Jiecheng temporarily change his job to one that would not require frequent business trips and would allow him to stay with his wife for a long time.

Weigh again and again.

Yan Jiecheng finally decided to change his job. He went to Li Cheng to explain the matter and talked about his ideas.

Yan Jiecheng came to work at the department store with Li Cheng. Li Cheng was of course responsible, but he went to find the manager of the public office to explain the situation and helped Yan Jiecheng change his job to a salesperson.

A salesperson’s job is stable and does not require travel, but the salary is not as high as that of a buyer.

but.

In order to help Yu Li get pregnant as soon as possible, Yan Jiecheng accepted a lower salary.

After Yan Jiecheng changed his job, the couple had more opportunities to eat at home.

They found that the food cooked by the three aunts was no worse than theirs.

When Yu Li cooks, she often uses Chinese herbs such as yam and wild yam, but the second son's wife often eats rice and flour.

After some inquiries, I found out that it was the third aunt who did it specifically for Zhang Lan so that she could get pregnant earlier.

Yu Li felt a little unbalanced.

originally.

They started the fight individually just to prevent their parents from taking advantage of them, but now they find that they can actually take advantage of their parents.

Yu Li discussed with her husband Yan Jiecheng that they might as well go back to Yan's house for dinner.

The mother-in-law makes delicious food for the second son's wife, and then she also makes some for herself.

Yan Jiecheng nodded and agreed.

in fact.

He had this idea a long time ago.

just.

When Yan Jiecheng told his parents about this matter, he was rejected.

Yan Bugui had a clear mind.

There are fewer food rations now.

The eldest brother and his wife cannot eat enough, or should we say, they cannot eat well, so they think of going back home to eat. Aren’t they just trying to take advantage and eat more?

How does this work?

Moreover.

The Zhang family gave them a lot of food!

People just want Zhang Lan and Yan Jiefang to fill their stomachs so they can have children, so how could they let the eldest brother and his wife take advantage of them?

"That's right!" Yan Bugui refused, "We have become accustomed to eating separately, so let's just keep it as it is!"

After Yan Jiecheng returned home, he told his wife about this matter.

Yu Li was a little unhappy, and snorted coldly, "Okay, then let's see who will have a child first, me or Zhang Lan. When I have a son, don't rush to curry favor with me!"

Among the neighbors in the courtyard, only Liu Yue and Qin Huairu, the younger generation, gave birth to two children.

Liu Yue gave birth to a daughter as her second child, who also had cleft lip and palate. Although Jia Xiaodang had undergone surgery, she was over one year old and still could not speak fluently, and she stuttered. Although she looked acceptable, she had undergone surgery after all, and had a scar on her mouth, so she did not look that good.

In general.

When it comes to childbearing experience, Liu Yue is not as good as Qin Huairu.

On weekends, Yu Li went to the hospital's family quarters to find Qin Huairu, wanting to ask for her advice on childbirth.

but.

Qin Huairu is working overtime at the pharmacy and is not at home.

Yu Li went to the pharmacy again.

There were quite a lot of people going to the Sixth Hospital's pharmacy to get medicine. Yu Li waited for more than an hour before she could talk to Qin Huairu.

Qin Huairu found a free time and left the pharmacy with Yu Li, and the two talked for more than ten minutes.

Qin Huairu did not deliberately conceal it and told Yu Li about the woman's menstrual cycle, ovulation day and so on. She said that as long as she remembered these things and as long as the couple were in good health, they would be able to get pregnant soon if they used them properly.

Yu Li was so happy that she felt like she had found a treasure. She insisted on taking Qin Huairu to a restaurant near the hospital for dinner, but Qin Huairu refused.

Qin Huairu felt that she had only spoken a few words to Yu Li and she didn't need to treat her to a meal.

Moreover.

Qin Huairu didn't want to take responsibility.

That was all she said.

No one can say for sure whether Yu Li can get pregnant in the near future.

After Yu Li left, Qin Huairu returned to the pharmacy.

Wang Qin asked Qin Huairu what Yu Li wanted to talk to her about.

Qin Huairu told her quietly.

Wang Qin blushed and wrote down Qin Huairu's words.

She is married now, so naturally she wants to get pregnant as soon as possible.

The end of March in the lunar calendar.

The locust flowers are in bloom.

The small flower spikes grew rapidly, and the locust flowers, which were shaped like little twisted feet and were about to bloom, formed strings of flower spikes, hanging on the branches like a beautiful woman's gold and silver jewelry. It was as if "suddenly a spring breeze came overnight" and "thousands of locust trees blossomed", immediately showing a unique and beautiful scenery.

When the locust flowers are in bloom, the snow-like whiteness will even cover the green background, creating a beautiful scene of "the snow was like flowers before, and the flowers are like snow now".

The locust flowers in the small courtyard of the hospital’s family quarters are in full bloom.

The flowers bloomed as beautifully as in previous years, but today they are a little different.

As soon as the flowers bloomed, Xu couldn't wait to steam some dishes and make some steamed cornbread.

Neighbors living near the family compound, including Liu Juan, Li Pingjing and others, have come to pick them several times.

Li Ping'an and his wife also picked locust flowers and sent them to Qin's father's family and Qin Huairu's second uncle's family several times.

Jia Zhang had always been thinking about the Li family's locust flowers, and she couldn't wait to go to the Li family to pick them several times.

The Jia family has tried all kinds of cooking methods, such as making steamed corn bread and steamed dishes.

Not just the Jia family.

The second aunt, the third aunt, and even Guyu and Zhao Fang have all gone to the Li family to pick locust flowers.

Li Pingan and his wife knew that the circumstances this year were special, but they did not stop them.

Anyway.

The Li family only has a few locust flowers, and anyone can pick them.

Just pick them and that’s it.

this year.

The Ministry of Health has drawn up several plans to complete the artificial production of insulin in the laboratory within a few years.

The Institute of Microbiology and Microbiology took on this task.

The Antibiotics Research Laboratory and the Chushan Laboratory of the Medical University also undertook some experimental tasks and cooperated with the Microbiology Laboratory to conduct experiments.

However, the Sixth Institute Laboratory did not participate in it.

The experiment of artificial insulin synthesis was too complicated. Li Ping'an felt that there were too few people in the laboratory of the Sixth Hospital. Even if he participated in it, he would not be able to share much of the task, and it would instead restrict his hands and feet.

The synthesis of artificial insulin involves several key steps, including gene cloning, expression, purification, and activity testing.

Researchers need to extract the DNA sequence of the human insulin gene from human cells. This step requires precise selection of the target gene and insertion of it into the vector DNA using gene cloning technology.

Then, the recombinant vector is transferred into host cells such as Escherichia coli, and cloned cells containing the target gene are obtained through culture and screening.

Next, the target gene needs to be expressed. In the cell, the target gene will be transcribed into mRNA, and then synthesized into protein by the cell's translation system. In order to increase the expression of the target gene, the production of insulin protein can be increased by regulating the transcription and translation levels in the cell.

Then the synthesized insulin protein needs to be purified. This step usually includes multiple steps such as centrifugation, filtration, chromatography, etc. to remove other impurities and impure substances to obtain high-purity insulin protein. The purification process requires the use of a series of chemical reagents and biotechnology methods to ensure the purity and activity of insulin protein.

Researchers also need to test the activity of synthetic insulin, which can be done through in vitro experiments or animal models.

Scientists will test whether the synthetic insulin can bind to insulin receptors in vitro and observe its regulating effect on blood sugar levels. Animal experiments will also be conducted to see whether the synthetic insulin can effectively lower the blood sugar levels of diabetic animals.

The process of synthesizing artificial insulin requires superb technology and rigorous operation. Through continuous research and exploration, the synthesis technology is continuously improved to improve the synthesis efficiency and purity of insulin protein.

We are just at the beginning at this stage, and I don’t know how many experiments and complex operations will be needed to achieve it.

In the time and space where Li Ping'an lived in later life, several key laboratories of the Ministry of Health, the Institute of Materia Medica of the Chinese Academy of Sciences and other departments worked together to complete the feat of artificially synthesizing insulin a few years later.

Li Pingan knew that even if he did not participate, the artificial insulin project would be successful, so there was no need for him to get involved so early.

Chu Shan and Wang Ping, a married couple, work in the laboratory for several hours every day, and sometimes even more than ten hours if the experiment requires it.

Wang Ping seldom has time to cook.

Li Ping'an asked Xu to steam some steamed buns with locust flowers and asked Xiaolu to deliver them to them.

After Xiaolu came back from home, she told Li Pingan that her parents were very busy at work and they could only make do with their meals, and the few steamed buns she brought with her were probably enough to last her parents for several days.

Xiao Lu sighed again and said, "It seems that the burden of taking care of Chu Kang will fall on me from now on!"

Li Pingan said: "Don't worry, Huairu and I will help you!"

Chu Shan and Wang Ping often called Li Pingan to discuss experimental matters. Li Pingan took this opportunity to advise them to take good care of themselves. After all, if their health collapsed, they would not be able to participate in any experiment.

The two of them agreed very readily, but I don’t know if they really remembered it.

Li Ping'an went to the Huirentang branch to deliver locust flowers to his father-in-law and mother-in-law, and met Ye Lina when he went to Xu Huizhen's tavern cafeteria for dinner.

At this time, Ye Lina no longer did business.

After her partner Vladimir became a diplomat, Yelina was stretched to the limit and her business went from bad to worse. In addition, public-private partnerships were everywhere now, and any business was difficult to do, let alone the silk business. The import and export trade of reselling domestic goods to the Soviet Union was controlled by the larger Soviet trading companies, and Yelina could not get any domestic orders at all.

just now.

She has married Vladimir and becomes a full-time housewife, serving her husband at home every day.

After talking to Ye Lina for a while, Xu Huizhen knew everything about her, even what Ye Lina did at home every day.

Li Pingan heard the conversation between the two while eating in the cafeteria.

In Li Ping'an's mind, Ye Lina has always been very bold. She would do any business and dare to do anything as long as she could make money.

She even encouraged Chen Xueru's tailor shop to do business with her, allowing Chen Xueru to evade taxes.

Such a strong-willed woman is willing to give up her business and become a full-time housewife at home. It seems that she really likes Vladimir, or Vladimir has a lot of money.

After returning home, Li Pingan occasionally talked about this matter with Chen Xueru.

Chen Xueru said that she knew about Ye Lina's affairs. Ye Lina was caught by the Soviet government officials because she was too bold in doing business. She was fined a lot of money and had no choice but to retire and marry Vladimir and settle down in the capital.

"Although it is not easy to do import and export trade with China, it is not impossible!" Chen Xueru said: "For example, Hou Da and his family, such as the Natasha family, they are still doing all kinds of business, and they are doing well!"

Li Pingan nodded and said, "It seems that we still have to take the right path, otherwise it will hurt others and ourselves!"
