"Tell me a few words, class monitor." Ren Chongda cleared his throat. As a gentleman counselor, he took the initiative to help the girls in the class resolve their predicament.
Yue Wentong looked at the person and then spoke: "What he said is definitely not easy to conduct an experiment. He can't even think of the specific infection."
This is something that everyone knows, so classmate Li, who couldn't express his thoughts, squatted on the ground and drew circles.
"Do 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, we want to do a verification experiment, which seems to be without purpose." 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 involves 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, and its main function is to support protective connections.
Myocardial cell muscle bundles, etc. 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 active factors such as cytokines that activate quiescent extracellular matrix-producing cells to transform into cardiac fibroblasts, ultimately leading to cardiac fibrosis."
After understanding this continuous pathological process, you can perform targeted fibrosis detection, such as detecting various products and components produced during the above evolution process. In the simplest example, you can detect the content of collagen fibers during experiments.
What these are for depends on the particularity of this pathological section, as Li suspected. Xie Wanying said: "It seems to be a hidden chronic evolution process, not an acute disease. If we do relevant experiments and speculate, we can
Use methods such as testing collagen fiber content at intervals to find hidden lesions."
After hearing this, other students looked at the monitor.
Yue Wentong: Well, I knew this earlier.
Classmate Li's heart immediately became balanced: the monitor hit him, and then the monitor was hit by classmate Xie's dimensionality reduction.
The teachers laughed on the spot. The gap between the students was indeed very obvious, and some of them had blank minds. This blank mind did not refer to knowledge reserves. Regarding the pathological evolution process cited by Xie, it is impossible for other top students present not to know about it.
It was the turn to transform knowledge into ideas for designing experiments, and other students had no clue.
"I told you, she seems to have done scientific research and is quite familiar with this field." Teacher Yuan Fang said to Cao Yudong next to her.
"Hmm." Cao Yudong nodded twice, the smile in his eyes grew thicker, and asked, "Do you want to do a similar experiment?"
Seniors are very good at reading people's thoughts. If they were not interested in academic issues in this area, they would not want to see slices like this, they would not be able to quickly find faults with the slices, and they would not be able to quickly come up with relevant experiments.
Design ideas.
Overall, Xie came well prepared.
The notice about coming to visit has been revealed for a long time in advance, almost a few months ago. Thank you for being prepared, which shows that you attach great importance to this visit and study.
In this regard, seniors like Cao Yudong feel very happy and happy. Therefore, when Mr. Cao asked this question, he had another profound meaning: If you are interested in doing something, maybe I can help you.
