"Class monitor, please say a few words." Ren Chongda cleared his voice. As a gentleman counselor, he took the initiative to help the girls in the class resolve their dilemma.
Yue Wentong looked at the man and said, "What he said is definitely not easy to conduct an experiment. He himself can't imagine what the infection is."
This was something that everyone knew, so Student Li couldn't continue to express his thoughts and just squatted on the ground and drew circles.
"You think his idea is not good. What do you think?" Teacher Yuan asked.
"Teacher, before we can guess the specific cause of the disease, it seems meaningless to do a verification experiment." Yue Wentong said frankly.
is that so?
Teacher Yuan let the ultimate character appear and asked Xie Wanying: "This is the anomaly you discovered first. What do you think about it?"
"The evolution of myocardial fibrosis first talks about the extracellular matrix, which includes collagen fibers, proteoglycans, glycoproteins and other substances. The extracellular matrix of the heart is mainly composed of type I and type III collagen fibers, which mainly support and protect the connection between myocardial cell bundles. Under normal circumstances, the extracellular matrix is in a static state. When stimulated by factors such as inflammation, ischemia, and hypertension, pathological changes occur in myocardial cells, which in turn triggers the defense function of the human immune system. Macrophages release cytokines and other active factors to activate the static extracellular matrix-producing cells to transform into myocardial fibroblasts, which eventually lead to myocardial fibrosis."
After understanding this continuous pathological process, targeted fibrosis testing can be carried out, such as detecting the various products and components produced during the above evolution process. The simplest example is to detect the collagen fiber content during the experiment.

...
The purpose of saying this has to do with the particularity of this pathological section, such as the direction of Li's suspicion. Xie Wanying said: "It seems to be a hidden chronic evolutionary process rather than an acute disease. If we do relevant experimental speculation, we can detect hidden lesions by testing the collagen fiber content at intervals."
After hearing this, the other students looked at the class monitor.
Yue Wentong: Uh, I should have known this earlier.
Student Li's heart immediately balanced: the class monitor attacked him, and then the class monitor was attacked by student Xie.
The teachers burst out laughing on the spot. The gap between these students is indeed very obvious, and some of them really have a blank mind. This blank mind does not refer to knowledge reserves. Regarding the pathological evolution process cited by Xie, the other top students present could not have been unaware of it. When it came time to transform knowledge into ideas for designing experiments, the other students had no idea where to start.
"I told you that she seems to have done scientific research and is quite familiar with this area." Teacher Yuan Fang said to Cao Yudong next to her.
"Yeah." Cao Yudong nodded twice, the smile in his eyes became more intense, and asked, "Do you want to do a similar experiment?"
The old senior is very good at reading people’s minds. If you are not interested in the academic issues in this area, you will not want to look at such slices, you will not be able to quickly point out the problems with the slices, and you will not be able to quickly come up with relevant experimental design ideas.
Overall, Xie came well prepared.
The news of the visit had been leaked a long time in advance, almost several months ago. Xie was well prepared, which shows that he attached great importance to this visit and study.
In this regard, senior colleagues like Cao Yudong feel very happy and delighted. So, when Mr. Cao asked this question, there was another deeper meaning: If you are interested in doing it, maybe I can help you.
