On the other hand, it is equivalent to saying that after the medical records were found, not only did the doubts not be answered, but they were deepened.
No wonder Teacher Yuan Fang just found the medical records here and thought about it for a long time without expressing her opinion first.
That’s it. Classmate Li Qian and others who couldn’t see the problem before finally understood where the “gold” that classmate Xie found was.
If you put it this way, could it be that the researchers made a mistake?
Let me start by saying that this is data collected in a database. Before the data is cited in scientific research papers, it has little to do with scientific research and can at most be used in today's teaching.
Ordinary data collection is most likely to be pathological slides made by students for teachers. When it comes to diagnosis, students temporarily quote the clinician's final diagnosis as a label, which cannot be said to be completely wrong.
"Are you saying it's definitely not a myocardial infarction? We can't say it's completely ruled out right now," Cao Yudong said again.
For some difficult and complicated diseases with unclear medical history, it is too difficult to make a clear medical diagnosis. In most cases, it can only become a point of discussion within the medical circle.
Unless the patient's family has follow-up needs for doctors to pursue the truth, they can only wait for doctors or researchers to suddenly have this interest or need to do the task, and then slowly and deeply explore the case. Who can let everyone, whether it is scientific research or clinical work,
I am too busy and have too many medical cases to deal with. Besides, everyone knows that for cases like this, it is very likely that the correct answer will not be obtained after discussing the case again and again.
Maybe someone thought of forensic medicine at this time. Can forensic medicine completely solve the mystery of everyone's death? The answer is no.
One of the foundations of forensic science is medicine. It is impossible for forensic medicine to make breakthroughs on its own when medicine cannot solve all medical mysteries.
Therefore, you will find in the news that some highly controversial cases are suspected of murder. In the end, the conclusion given by the forensic doctor is that there is no conclusive evidence of murder. It can only be said that the patient died of an ordinary death.
Organ failure and the like.
At this point, Teacher Yuan Fang once again mentioned Xie's cautious style: "She didn't say it wasn't myocardial infarction, only that it was atypical. She wanted to check the medical records and gross specimens again."
If the gross specimens and medical records can prove that it is myocardial infarction, this pathological section can become a special case among the pathological sections of myocardial infarction and serve as valuable teaching material for atypical cases. Therefore, Xie’s cautious suspicion is very meaningful.
"Do you have any rough specimens?" Cao Yudong asked his colleague.
Teacher Yuan Fang said: "I'm afraid this may not be possible."
Gross specimens are more difficult to preserve than sectioned specimens, occupying more space and consuming more resources. Not all organs of a body can be preserved as gross specimens. The organs for gross specimens must be selected, and generally those with research value are selected for preservation.
Moreover, during the preservation process, if some general specimens have problems due to some unpredictable factors over the years, they will have to be eliminated.
In short, it is very expensive for scientific research institutes to engage in these things, even if they use dead people for research.
Without gross specimens, the only way to continue exploring this case is by relying on the only fragmentary data available.
Speaking of the biggest feature of this pathological section, it is a large area of myocardial fibrosis. If you remember Xiao Shugang's case, it was mentioned that ischemia causes myocardial cells to die and become cardiac scars, which refers to myocardial fibrosis.
