"Yes, if you do find pathogenic bacteria in the stomach of a patient with stomach problems, then you can prepare for the graduation defense, of course, for a master's degree. ”

Ye Minde said to Zheng Jianguo with a solemn expression, looking at his obviously surprised expression, and also felt that this difficulty was a bit big, since the microscope was invented more than three hundred years ago, human beings have a sharp tool for observing the vast majority of microorganisms around them, especially the emergence of the electron microscope in the last twenty or thirty years, which has brought the research in the direction of microorganisms into a new stage.

At that time, the microscope was just appeared, especially represented by the pioneer of histology and embryology, the Italian comrade Malpiki, who used the microscope to observe the tissue structure of biological objects, researchers and scientists took the microscope to see almost the whole world, and finally wanted to cut themselves into slices and put them below to see, and since then it has been centuries, how can it be so easy to find an undiscovered bacterium?

Or do you want to find it in the stomach of a strong acidic environment?!

Ye Minde turned around and left after speaking, in terms of the current relationship between the teacher and the student, he is not good at dampening the enthusiasm of this proud protégé, in the environment in the stomach, those with a little chemical foundation know that it is impossible to exist in life, even if it is impossible to survive in it, let alone destroy the gastric mucosa that continuously secretes gastric acid to survive in it, wait until this product finds a stomach disease patient first, as for how to calculate the waste of time?

Zheng Jianguo's age is too young, he only scored 79 points in the basic professional course, and he still has time to learn slowly.

Someone doesn't know that his research has been drawn by his mentor in advance, because the bacteria he is looking for in his memory are almost known to passers-by, and in terms of scope, this thing is probably one of the most pathogenic bacteria known to normal people in his memory.

Of course, this reason is also caused by a large group of stomach problems.

Knowing that he would be able to defend his master's degree if he found this thing, Zheng Jianguo's fighting spirit was raised, he was contrary to the vast majority of researchers who thought that bacteria could not survive in the stomach and did not study it deeply, he knew that this thing was in the body of the vast majority of patients with stomach problems, and the difficulty was how to find it, especially when he didn't know what it looked like.

Where does Helicobacter pylori branch after infection?

Most people will say that it is in the stomach, and most medical workers know that this thing starts with tartar and calculus in the mouth, passes through the esophagus and reaches the stomach to survive, and then continues to enter the intestines with the help of food digestion, especially in the duodenum, where it opens up a second home, and the rest continues down until it is excreted with feces.

These are all in Zheng Jianguo's mind, of course, he didn't dare to write them down, and when it was discovered, it was not that he was going to study people's homes, but that he was cut into slices and studied: "Now patients with stomach problems, let the gastroenterology department of the People's Hospital count again or go home to find the people in the team?"

Since he used gentamicin to cure Zheng Donghua's stomach pain, Zheng Jianguo asked his father Zheng Fugui to give priority to dysentery and the more expensive gentamicin when prescribing medicine to patients with stomach pain in his daily medical practice, and also made a simple record of the names and time of these patients and the treatment effect, the purpose of which is to support the questions and hypotheses he is putting forward now, and from the beginning of last year to the middle of the year, there must be a lot of data, so he is not short of stomach patients, but he is not in front of him.

I don't know if the fourth sister Zheng Donghua has a stomach problem, did she commit it again?

No, how can you hope that the fourth sister has stomach problems?

Such a thought flashed in his mind, and then Zheng Jianguo, who secretly scolded himself for being wolf-hearted, his eyes lit up, and Yi Jinzhi appeared at the door of the room outside the window, and greeted him: "Sister Yi, is there something wrong with me?"

"It's okay, just come and see the graduate students of our school. ”

Yi Jinzhi stood at the door and leaned against the doorpost and said, a bright smile appeared on his round face after a pair of eyes swept over the room, and he turned his head and said loudly: "Come on, the graduate students of our school are here." ”

"Really?"

As the voice sounded, Zheng Jianguo found that three or four faces appeared in the window, and he heard Yi Jinzhi say with a smile: "This is my friend, I want to see the youngest in our province——"

"Sister Jin Zhi, you are wrong, she is the youngest graduate student in the country. ”

The girl who opened her mouth had two pigtails, the long white and clean was wearing a white and good shirt, and the lower body was wearing a rare slip dress that was over the knee, and a pair of eyes fell on his face as if she could speak, and nodded generously to Zheng Jianguo after saying to Yi Jinzhi: "Hello Zheng Jianguo, I'm Shi An'an from the 1977 journalism class 2 of Qi University, I'm here to interview you, you are more difficult to see than the principal——"

"Our principal is not famous~"

Zheng Jianguo was shocked by the girl's dress, he didn't expect to see such a dressed girl in China at this time, a pair of eyes swept over Yi Jinzhi next to him, and saw that she was thinking thoughtfully with a pair of eyes, and his eyes lit up: "You stuffed that note, right?"

"What note?"

Before Yi Jinzhi could speak, Shi An'an's big eyes glanced at the two of them, and then a pair of round eyes bent into crescents: "Sister Jinzhi, did you write him a note?"

"I don't like little men. ”

Yi Jinzhi looked at Shi An'an with a disgusted face, and Zheng Jianguo's face darkened, but fortunately, he knew that this sister's mouth was most likely unintentional, and the expression on his face was much better: "Shi An'an, you came to interview me, are you going to publish it?"

"Definitely, I'm not a long-tongued woman for the sake of publication. ”

Shi An'an's little face flashed with surprise, and he blinked his big eyes and raised his chin slightly: "I just said, I'm from the journalism department, I said it, right?"

"Yes, but I don't think graduate school is happy. ”

The girl named Lili has a long face, a traditional goose egg face, a pair of eyes that seem to have a little squint, and she is wearing a light blue gown and brown pants, but unlike the latter's sandals, she wears a pair of small leather shoes on her feet.

Shi An'an's gaze swept over the calm expression of Zheng Jianguo's face, and his chin was slightly raised: "Zheng Jianguo, why don't you like to be interviewed? It is said that you are now a master's student, and the little carpenters are very cooperative with the reporters' interviews." ”

"I don't know what to say, I'm afraid that if I say something I shouldn't say, I'll be put on the platform, so I feel like it's better not to say it. ”

Zheng Jianguo met her gaze, it can be seen from the white skin color that this is definitely not an ordinary child, people say that one white covers three ugliness, which describes that white can cover the shortcomings of the face and reduce the shortcomings of the face, eye shape and nose shape, most of the ordinary people at this time have skin like Yi Jinzhi, otherwise they will be a little bronze like Zheng Donghua, but there will rarely be this kind of white that does not see the sun: "I'm sorry." ”

"You're boring. ”

The girl named Lili looked at Zheng Jianguo and didn't seem to be fake, of course, she couldn't see the real thoughts of this person with her skills, so she turned her head to look at Yi Jinzhi and said, "Sister Jinzhi, didn't you say that he was very talkative?"

"Well, forget it if he doesn't give interviews. ”

Thinking that the two of them were blocked for the first time and almost cried, Yi Jinzhi also found that he felt more and more the unfathomable profundity of this product, just looking at his appearance at this time, it was really difficult to connect with Zheng Jianguo when they met for the first time, but Shi Anan is not an ordinary person, he was able to find himself in a detour, it can be seen that the curiosity about this person is also unstoppable, this kind of person can not be easy to befriend, if he is offended, I am afraid that it is enough to impress people now, after finishing speaking, he turned his head to look at Zheng Jianguo, who had a calm face, and said: " If I admit that I reminded you to check your results, would you be willing to be interviewed by An An?"

"Well, that's fine. ”

His eyes lit up, Zheng Jianguo glanced at Yi Jinzhi, he didn't expect that the note was really written by this sister, there were not many people in the school who had intersections with him at that time, and then remembered the attitude towards people when they met for the first time, nodded and looked at Shi An'an next to him and said, "Shi An'an, you can ask, but I will only answer you three questions." ”

"Now, you two—"

The snow-white little face was full of curiosity before he wanted to speak, Shi An'an suddenly came back to his senses and asked this question, but it was just a question, he quickly turned his head to look at Yi Jinzhi, turned around and quickly took out a notebook and pen from the bag behind him, glared at Zheng Jianguo and said: "Qi Provincial Daily said that you have loved learning since you were a child, and you didn't forget to study when you were about to graduate from high school, and even after learning those high school knowledge, you took the initiative to find previous textbooks, especially the "Mathematics, Physics and Chemistry Self-study Series" to study, is that so?"

"In a sense, yes, but the report deliberately weakened my motivation to study and magnified my learning experience, I saw at home that some educated youths were eliminated because of failing the exam, and found that what I learned in school was no different from what they learned, so I felt that the agricultural and industrial bases taught in high school were useless, so I germinated the idea of looking for a "Mathematics, Physics and Chemistry Self-study Series", and later found it with the help of my friends before I started learning. ”

Zheng Jianguo's statement made Shi Anan distracted, she was not surprised that Zheng Jianguo could answer herself truthfully, but from the mouth of the graduate student who just said "I don't know how to say", it turned out to be the behavior of revealing her old background: "Are you saying that you went to find a series of books to study for yourself in order to take the workers' exam, and then when you wanted to take the workers' exam, you encountered the resumption of the college entrance examination?"
