I can see the status bar

Chapter 776 Contradiction Theory
The speculation of tumor is not groundless.

Imaging evidence supports the tumor speculation, and Sun Li'en doesn't think Luo Ge will make a mistake on this kind of problem - as a radiologist with many years of work experience, he has seen countless malignant tumors.And being able to discover this kind of hidden lesion itself shows that Luo Ge's level of experience is still enough.

If Luo Ge's guess is correct, then there is no prompt in the status bar... It seems to make sense - the main source of Tang Min's symptoms is severe interstitial cell edema caused by insufficient expression of AQP4.The source of all her symptoms is this congenital genetic disease, and until the tumor expands to a certain extent, the symptoms are hidden and can even be regarded as "asymptomatic".Therefore, it makes sense that there is no prompt in the status bar.

There is no prompt in the status column, which can be regarded as side evidence of tumor diagnosis.And cerebral ischemia can't be justified if there is no state-even if it is "asymptomatic cerebral infarction" or "quiescent cerebral infarction", it will not be completely asymptomatic.It will at least have symptoms such as dizziness, headache and numbness of limbs and memory loss.

If there are symptoms, there will definitely be relevant prompts in the status bar-as for the specific name of the disease or clues enough to diagnose, this is not necessarily the case.

Then, the next problem to be solved is relatively simple.Sun Lien was silent for a while and continued, "We need to figure out what type of tumor this is and why the tumor suddenly disappeared."

"If it's a tumor, I have an idea." Yuan Ping'an interjected, "Judging from the area of ​​the disease, it's more likely that this tumor is a glioblastoma, right?"

Luo Ge nodded, "Several locations of the disease are in the white matter of the brain, away from blood vessels and glands—these locations are most likely to be glioblastomas."

"Tang Min's AQP4 expression is insufficient, which also affects her glial cells." Yuan Ping'an frowned, "I remember reading that AQP4 expression is closely related to brain glioma..."

"Positive relationship or negative relationship?" Zhou Ce asked, "She now has insufficient expression of AQP4 protein, and we have temporarily improved her hydrocephalus through drug effects. If it is a negative impact...won't it be necessary to stop the treatment later? "

It's a hypothetical that makes a cold sweat run down your back.If the working efficiency of AQP4 protein increases, it will lead to glioblastoma, then doctors will have to re-evaluate the treatment plan for Tang Min.The family members also need to choose one of the two cruel options of "suffering from cancer" and "death from hydrocephalus".

"Not necessarily... what if the cancer is primary?" Xu Yourong had different opinions on this, "If there is a negative impact, how can it explain the disappearance of the space-occupying lesions? The area of ​​each lesion is not small, but in the Before they become solid tumors, the mass is absorbed. These mass are not the size that the immune system can handle by itself."

"So..." Sun Lien concluded, "Is there any factor that prevented or curbed the development of the tumor in her brain. And this factor seems to be related to AQP4 at present?"

The meeting room fell into silence, and everyone was thinking about Sun Lien's speculation with their heads down.Soon, they discovered that, no matter in terms of logic or the characteristics of the disease itself, this speculation did have the possibility of coming true.

"I'm going to improve the statistics of papers in this area." Yuan Pingan volunteered, "Look it up in the previous browsing records, and you should get results soon."

"I suggest increasing the frequency of observation. Anyway, the MRI downstairs is still on." Luo Ge suggested, "Re-increase the frequency to once a day. If necessary, you can consider going to another hospital for PET. If it is really a tumor , that also needs to start intervention as soon as possible, tumors appear in multiple areas in the same organ, which is close to the third stage."

Cancer cells are very unstable abnormal cells, and their abnormality is also manifested in easy shedding.Most normal human cells are tightly connected with other cells and play their due role.Cancer cells lack this feature—they can easily detach from existing clumps of cancer cells and follow the blood or lymph to other locations in the same organ, or to other organs.This is cancer metastasis.

"If you look at it from this angle...it really doesn't look like cancer." Bruen muttered, "The tumor itself is not too big, and it was absorbed before it formed a complete solid mass. But there are Extensive intra-organ metastasis... These two symptoms are completely contradictory as a cancer grade."

Dr. Pascal continued, "Anyway, Dr. Sun usually meets a lot of strange patients. Even if I meet a patient with innate immunity to cancer, I wouldn't think it's so strange." He turned to Sun Lien and said, "Biochemical tests are also Let’s improve it together, and check markers such as TSGF and CD133.”

Sun Li'en nodded, turned around and began to give the doctor's order.The other doctors continued to discuss in low voices.

"What you just said gave me some inspiration." Yuan Ping'an moved his buttocks, sat next to Dr. Pascal and said, "Is it possible to be immune to cancer?"

"As long as it is a multicellular organism, it is impossible." Dr. Pascal rolled his eyes. "Multicellular organisms need to divide cells to maintain tissue activity. Errors in gene replication are inevitable, so the immune system will attack the cells that have gone wrong To prevent cancer... This is the content of the textbook." He said seriously, "The strength of the immune system can prevent cancer to a certain extent, and the best counterexample is the previous case of 'cross-species transmission of cancer' Report."

"That HIV-positive patient suffered from cancer. Immunohistochemistry found that the cancer cells came from roundworms, right?" What can stop a cancer cell that has already spread from multiplying?"

"Where can I go? I'm not an expert on cancer." Dr. Pascal called Xu Yourong who was sitting on the side, "Your wife is an expert on cancer, what do you think?"

"I know too much about cancer." Xu Yourong replied very naturally, "In the past, after brain tumor resection, we would basically send the patient directly to the oncology department for treatment. The relevant chemotherapy plan is also prepared by them."

The topic came back to the original point, Yuan Pingan shook his head, "Forget it, I'd better read the literature." He stood up and stretched, "I thought Tang Min's case was basically over..."

"Group Leader Sun has spoken, why don't you take the time to read the literature?" Zhou Ce smiled and said, "Maybe this is a great discovery of the Nobel Prize level."

"Forget it." Yuan Ping'an shrugged his shoulders, shook his head and said, "The Nobel Prizes are all given to old men. I don't want to have to plan my life after I retire to see when I can receive a call from Sweden." Telephone—I don't understand Swedish."
