What the classmates and seniors around him want to ask most is whether Xie has made any new discoveries.
I saw that student Xie suddenly looked at a pathology section again and again.
"Yingying, what did you see?" Li Qian'an couldn't hold it in any longer and leaned down to ask her.
Teacher Yuan Fang walked over and, without interfering with her observation, checked the serial number in the slide box to roughly infer which pathological section she was looking at.
Several other big guys followed over, took a look, and asked Teacher Yuan: What’s going on? What is it?
"It's a pathological section of a patient with myocardial infarction," said teacher Yuan Fang.
Myocardial infarction patients are not rare cases in today's clinic. There should be many such pathological sections, so why did she insist on this one?
Cao Dong directly asked the person involved: "Do you have any questions?"
Hearing the voice, Xie Wanying took her eyes away from the eyepiece and turned back, with a look of surprise on her face.
...
...
Cao Dongfang realized that she had not known he was coming.
The name of being stubborn is well deserved.
"Teacher Cao Dong." Xie Wanying politely addressed the big boss of Guodu.
After understanding the question the boss had just asked, Xie Wanying did not hide it and answered: "I am thinking about the pathological section of this myocardial infarction patient. It may be necessary to combine the specific patient's medical history and gross specimens."
For pathological observation of myocardial infarction, if conditions permit, the first step is to observe the gross specimen, that is, to observe the entire appearance of the infarcted heart. Basically, the infarction focus will appear grayish yellow and soft and edematous in the early stage, and in the later stage it will become grayish white and dull, with the surface sunken like a landslide, and the hard part from the soft side is the formation of scar tissue.
The corresponding histological observation of pathological sections showed that the nuclei of necrotic myocardial cells fragmented and disappeared, and inflammatory cells were seen nearby, then granulation tissue formed and finally replaced by fibrous scars.
Therefore, by observing the pathological sections, we can roughly infer from these evolution processes at which stage of the patient's myocardial infarction development the specimen was taken.
This is what Mr. Xie meant. If you only look at this slice, it is atypical and it seems impossible to tell which stage of case development it belongs to.
In other words, whether this case is a myocardial infarction biopsy may need to be questioned.
After Yuan Fang and Cao Dong made eye contact, Cao Dong, without saying anything, moved the microscope on the operating table towards himself, stood up, bent down and put his eyes to the eyepiece, wanting to confirm what she said with his own eyes.
After waiting for a while, we could see that Cao Dong's eyes were almost glued to the eyepiece, which showed that the problem Xie mentioned was real.
Teacher Yuan Fang was a little nervous and asked, "How is it, Doctor Cao Dong?"
"I think she is right. This is a slice of myocardial necrosis. We need to check the medical records to see if this patient has myocardial infarction." Cao Dong said.
Myocardial necrosis and myocardial infarction are two different things.
Myocardial infarction, as the name suggests, is myocardial necrosis caused by coronary artery ischemia, hypoxia and obstruction. In the case of myocardial necrosis, the cause is not limited to myocardial infarction.
If the patient is very unlucky, he/she dies suddenly before being admitted to the hospital or dies immediately after being admitted to the hospital. The patient's family and friends cannot explain why the patient's condition before death led to the onset of the disease, such as the case of her grandfather. Now it seems that if we rely solely on pathological speculation, we need similar data to withstand reverse inference.
Perhaps this atypical slice could give her some ideas.
