Chapter 195 found unknown bacteria

Niu Meiqi and Lan Lizhen share the same dormitory. She was working overtime at this time, and it was a little strange to see Lan Lijuan coming in:

"Lijuan, why did you come to the laboratory?"

Lan Lijuan raised a watermelon in her hand and said with a smile, "I want to borrow your microscope to do some experiments."

Not far away, Zhao Ning, the director of the inspection department who was also working overtime, raised his head and said with a smile:

"Our clinical doctors finally think of our hard-working auxiliary departments? See, you all finished your lunch, and we are still working overtime."

Lan Lijuan hurriedly said politely: "Director Zhao, I intend to kill the enemy, but I can't recover from it. The work of your laboratory department is too professional, and I can't help you even if I want to."

"Hehe, no need to help, by the way, what experiment do you want to do?"

"Are there many gastric mucosa specimens in our laboratory?"

Niu Meiqi replied: "Not many, our hospital only has one gastroscope, so there are not many examinations, only two biopsies today."

Lan Lijuan pointed to the microscope and said, "I just want to observe the gastric mucosal biopsy to find inspiration for future projects."

Director Zhao was a little puzzled: "Lijuan, you just started working not long ago, and it's your turn to get the subject?"

Lan Lijuan smiled wryly: "Director Zhao was joking, I just want to find inspiration when I get it, so I can't just stop researching without a topic, right? If you really need it, you can do it at your own expense."

Director Zhao is not at all awe-inspiring: "Oh, well said, it is a good thing that young people want to make progress. You can use the machines in our laboratory as you like."

After getting rid of the boss of the laboratory department, Lan Lijuan also got the Shangfang Baby Sword, so she quickly sat next to Niu Meiqi.

Niu Meiqi brought over two specimens of gastric mucosa: "Here, these two specimens have been tested, and you can do whatever experiment you like."

"thank you."

"It's okay, you are busy with your work."

Lan Lijuan put the specimen under the microscope, adjusted the aperture to focus well, and was impatient to find the spiral-shaped unknown bacteria that her boyfriend mentioned, but she searched the two specimens several times, and a spirochete None were found.

I felt a little depressed all of a sudden. I don't know if it's my level or the specimen.

"Mei Qi, what kind of patients are these two specimens?"

"It's all gastric ulcers. I did a biopsy to test whether it's gastric cancer. What's wrong? Do you have any new discoveries?"

"Stomach ulcer?"

Lan Lijuan thought to herself, isn't this the key group of unknown pathogenic bacteria that Chen Qi mentioned? Why can't I find any of them?

"Mei Qi, I want to look for some special bacteria in the specimen, how do you think I should find it correctly?"

"Special bacteria?"

Niu Meiqi raised her head and pointed to the dye next to her.

"Try to do Gram staining first, but Lijuan, how could there be bacteria on the gastric mucosa? It's full of stomach acid."

The current mainstream view at home and abroad is that the stomach is suitable for the growth of bacteria, because stomach acid can kill all bacteria.

Before the discovery of Helicobacter pylori, the mainstream view was that stomach diseases such as gastritis and gastric ulcer were caused by improper diet, certain drug stimulation, or stress response caused by emotional agitation.

This is also written in the original textbooks.

But it is precisely because no real cause has been found that gastritis was considered incurable before Helicobacter pylori was discovered.

Being questioned by her colleagues, Lan Lijuan blushed, "I'm looking for inspiration, haha, what if there is?"

Niu Meiqi didn't care too much. Anyway, when she was doing a project, she was just looking for an entrance in a whimsical way.

Lan Lijuan also hurriedly followed the steps and started staining patiently. After finishing some work, she took the slides to the microscope for a look, and she was pleasantly surprised.

She really saw curved bacteria in the camera, with a lot of flagella at one end. Could this be the unknown pathogenic bacteria Chen Qi mentioned?

Lan Lijuan changed another specimen and observed again. This time she also found the bacteria on the gastric mucosa, but the shape of the bacteria in the previous specimen was different, but they also had flagella.

This made Lan Lijuan a little unconfident. Which one is the unknown pathogenic bacteria that Chen Qi mentioned?

But she was still a little excited. At least Chen Qi's hypothesis of bacteria in the gastric mucosa was established. This is indeed a topic worthy of research, and it is extremely subversive. It has been really confirmed, and even the textbooks have to be rewritten.

There is no WeChat these days, so it is impossible to ask immediately.

Lan Lijuan borrowed red pens and blue pens, and she could only draw down the shapes of bacteria she observed, especially the flagella structure. She drew them carefully and planned to send them to her boyfriend so that he could identify them too. .

Niu Meiqi finished her work, glanced at it when passing by, and asked strangely:

"Hey, Lan Juan, what are you drawing? Is this bacteria? It was found on a gastric mucosal specimen? How is it possible? The specimen is probably contaminated."

When Lan Lijuan heard this, she felt that this possibility was not ruled out, so as Chen Qi said, more experiments were needed.

At this time, she also made up her mind to go back and learn the operation of gastroscopy first, and then take care of the entire internal gastroscopy work by herself.

Doing this will increase her workload and make it easier for others. I believe her colleagues are also optimistic, and she can get the specimens and do experiments by herself, so she can master the first-hand data.

Waiting for the study of these unknown pathogenic bacteria to be almost done, first-hand evidence is obtained, and the number of specimens is sufficient, this paper will then find the director of the department, and the hospital must recommend it for publication.

At that time, give Chen Qi the first author, so that it will be more possible for him to transfer back to the urban area to work.

Lan Lijuan thought of this, and secretly encouraged herself, ready to roll up her sleeves and work harder.

This is the advantage of Chen Qi, a reborn person.

In fact, it is very simple to search for some unknown bacteria in the gastric mucosa, but in this era, everyone's thinking is imprisoned and limited.

Like Niu Meiqi, she naturally believes that it is impossible to have bacteria in the part soaked in gastric acid, and occasionally it is found that the specimen is contaminated.

However, some doctors do not believe in this evil. Two doctors in Australia, like two doctors in Australia, are constantly looking for it. After finding it, they are trying to prove that this spiral-shaped bacterium is directly related to the occurrence of stomach problems.

Then they succeeded, winning the Nobel Prize in Medicine.

It's that simple, but because of its simplicity, if you don't find the right direction, thousands of experiments will be in vain and useless.

Chen Qi is a reborn person. All his experience and knowledge are built on the shoulders of giants. He is now 40 years ahead of this era.

Maybe one day, he and Lan Lijuan can also become "giant".
