Siheyuan: My Northeastern Farmhouse

Chapter 151 Midterm Exam
Gu Weijun was already confident. He went back to space and looked for the textbooks he used when he was studying medicine. One of the courses was called organic chemistry. There were chemical structural formulas and chemical synthesis processes for cimetidine and ranitidine, but they definitely couldn't. Just throw it out like this, one is a way to explain, the other is something that is too easy to obtain and will definitely not be taken seriously!
Isn't it just making up a story?Gu Weijun, who is the soul of future generations, said that there is no pressure in the drizzle, and he has heard too much!

Gu Weijun smiled slightly and started talking about the theory of traditional Chinese medicine. "The dialectics of stomach diseases in traditional Chinese medicine mainly include several aspects: weakness of the spleen and stomach, disharmony between the liver and stomach, dampness and heat in the spleen and stomach, insufficient stomach yin, etc. From the perspective of Western medicine diagnosis, gastric ulcers and other diseases are mostly The two main types are disharmony between the liver and stomach and dampness and heat in the spleen and stomach.”

"From the perspective of seven emotions, Chinese medicine believes that the liver is responsible for anger, and the spleen is responsible for thinking!" "So the treatment direction of gastric ulcers in traditional Chinese medicine is to soothe the liver and regulate qi, harmonize the stomach and relieve depression! For example: Xiaoyao Pills!" "Mr. Chen, we It was also confirmed in the last communication that patients with gastric ulcers who develop gastric ulcers when they are angry or overthinking are significantly more than ordinary patients."

"What does this mean? It means that mood swings can cause excessive gastric acid secretion!" "Western medicine has discovered a substance: histamine, which has an amplifying effect on emotions, so we will look for chemical formulas that antagonize histamine receptors. Ah!" "Histamine receptor antagonists can reduce gastric acid secretion!"

Mrs. Li and Mr. Chen both agreed with great joy, "That makes sense!"

"Also!" Gu Weijun continued to fool, "Since there are two kinds of emotions that affect gastric ulcers, there must be two kinds of histamine receptors, one is excitatory and the other is inhibitory. What we are looking for is this inhibitory combination. Amine receptors!”

Mr. Chen cried with joy and said tremblingly: "That's right, that's right! After communicating with classmate Gu last time, I specifically asked my foreign classmates, and they said that the newly discovered histamine receptors indeed have two! They use diphenhydramine. The first histamine receptor has been confirmed, and now foreign scientists are also studying and looking for the second histamine receptor, which affects gastric acid secretion!"

Mrs. Li held her hands and smiled, her eyes shining, "Great! Director Chen! Classmate Gu! With this direction, we will definitely discover this inhibitory histamine receptor antagonist soon. Let's just call it H2 antagonist, right?" "

"Is history so similar?" Gu Weijun thought to himself, and on the surface he agreed very much, "Professor Xu is right!"

Mrs. Li said to Mr. Chen: "Director Chen, let's get started. We are divided into two groups. One group will synthesize histamine through different chemicals, and the other group will analyze what molecular formulas may be found in the traditional Chinese medicine Xiaoyao Pills. Affects gastric acid secretion!”

Mrs. Li pulled over the blackboard in the laboratory and wrote the molecular formula of histamine on the blackboard: N-NH-NH2, and then wrote down the traditional Chinese medicine ingredients of Xiaoyao Pill: Bupleurum, Angelicae, White Peony, Atractylodes, etc.

Mrs. Li tapped the chalk on the blackboard with a serious expression, "We have two goals. One is to find the second receptor for histamine; the other is to analyze the chemical formula that effectively inhibits the histamine receptor!"

With Mrs. Li's order, the entire laboratory immediately started running, and various chemical synthesis tools such as powders, distilling cups, and alcohol lamps, as well as analytical tools such as centrifuges and microscopes, were all put into use.

Yang Yu also hurriedly worked as an assistant under the command of a bespectacled woman beside him, sometimes dissolving, sometimes dropping, and sometimes separating.
Mrs. Li took Mr. Chen and Gu Weijun to analyze the direction of histamine receptors based on chemical theory and pharmaceutical theory.

Looking at the histamine molecular formula drawn by Mrs. Li on the paper, Gu Weijun drew a stroke on the NH2 side with itchy hands and said categorically: "The molecular formula of the receptor must be in this direction!"

Mrs. Li nodded, "Yes, this direction is the easiest to perform molecular exchange! Let's start from this direction!" The real experiment is very boring and requires bit by bit research. Gu Weijun followed Mrs. Li and Mr. Chen felt dizzy after doing the theoretical orientation all morning. He left in the afternoon on the pretext of going to the steel rolling mill to work as a liaison officer.

Mrs. Li saw that Gu Weijun had already made some contributions and his absence would not have much impact, so she waved her hand and let him go, leaving Yang Yu alone to continue doing chores.

Gu Weijun did go to the steel rolling mill in the afternoon. I don't know if they were stimulated by each other. The technicians of the steel rolling mill, the teaching teachers from Tsinghua University, and several top students were all working overtime, and they had already implemented the theoretical research on the drawings to the specific production line optimization tests.

Although it is only a small part of the process, a good start is half the success. Over time, the entire production line will definitely be qualitatively improved. By then, the strength of the steel plates will be improved, which will be a strong contribution to the entire national defense!
Gu Weijun could only get a rough idea, and after meeting with Teacher Wang, he asked the students where they needed him to communicate with the steel rolling mill in terms of logistics.After getting all the satisfactory answers, he left gracefully and returned to Beichizi Street.

In the Beichizi courtyard, Gu Ma, Qin Huairu and Shang Qiu were washing the baby's clothes and diapers. Bai Ling and Shang Chun were holding their children in the house, chatting through the curtain with the door open.Everyone was surprised to see Gu Weijun come back. Gu's mother asked directly: "Are you busy today? Why didn't you go back to Nanluogu Lane?"

Gu Weijun nodded and went back to the house to move a chair and make a pot of tea before returning to the courtyard. He stretched, slumped down on the chair and took a sip of tea. "Finally, two things have come to an end. I come back to be lazy! I have been extremely busy these past two months! I have to go back less often to Nanluogu Alley, because every time I go back there is a lot of trouble!"

Bai Ling said with a smile: "Chief Gu, you are now a celebrity in the factory! It was rumored before, why didn't people see you as soon as you were promoted? But now teachers and students from Tsinghua University have come to the factory, and the workers We are all convinced! Although we all know that Secretary Huang is a capable leader, we still need Section Chief Gu to be young and lively in thinking to implement it!"

Gu Weijun waved his hands modestly, "I just do needlework, it's not worth mentioning!" Then he asked lazily: "Why aren't Zheng Chu, Hao Chu, and Brother Wei at home? Everyone should be resting today?"

Bai Ling replied with a smile: "Old Zheng and Old Hao went to the city bureau to get some education. Ping An went back to her parents' home with Juanzi. Juanzi is about to give birth, so she quickly went back to her parents' home to get married."

"Oh" Gu Weijun trailed off and sighed slightly, "Sister Bai, Sister Chun, we haven't had a dinner together for a while. I have a car now. I will go out of the city to get a sheep in the mountains and come back later, so we can all get together." Make up for it!”

Gu's mother directly criticized the silly elder, "Why are you so greedy? I think you have no time to spare! As soon as you have time, you start thinking about eating!"

Gu Weijun rolled his eyes, I have made so many contributions, what's wrong with eating?He didn’t take advantage of the public!
After drinking a pot of tea, Gu Weijun drove around for a while, loaded a sheep into the car and returned to the city. He picked up Aunt Wang's family and notified Xiaoyu's and Tiezi's families before returning to Beichizi Street.

Gu's mother said she was disgusted, but when the steaming mutton hot pot was served in the evening, she was also smiling. Ever since Gu Weijun went to Tsinghua to study, there has indeed not been such a lively meat-eating!
How to relieve worries?Only Du Kang!In the evening, Gu Weijun and a few gentlemen drank and fell asleep on Beichizi Street. Qin Huairu's eyes were watery and moist, and then in the middle of the night
As soon as class starts next Monday, November 11, the teacher announces the time for the midterm exam, which will be from Monday to Wednesday, that is, from the 2th to the 9th.Suddenly there was a buzz in the classroom, followed by the sound of books being turned over!
