Sun Lien rubbed his eyes, and the display of the status bar did not change. The line of status bars floating over the patient's head is exactly what it says.

What is going onSun Lien took out the MRI examination report again, and the images on it clearly showed that there was no abnormal condition in the patient's brain.

An MRI was done yesterday at 3 p.m. and nothing unusual was detected. I did it again at nine o'clock this morning and still didn't find anything out of the ordinary. After completing the examination at around 9:30, Zhou Jun adjusted the patient's medication according to the opinions of rheumatologists......

In the five and a half hours of adjusting the medication, what exactly happened to cause this change Sun Lien frowned, and he didn't need the status bar prompt, he could guess that this was probably the main cause of the patient in front of him. At least one of the main reasons.

"Have you checked the cerebrospinal fluid pressure?" Sun Lien walked next to the patient and asked Zhou Jun. When collecting cerebrospinal fluid, cerebrospinal fluid pressure is generally not measured incidentally. Unless the patient has a clear indication of elevated intracranial pressure. The presence of a mass lesion in the brain basically means that the patient's intracranial pressure will increase. At this time, the cerebrospinal fluid pressure is checked, although there are some risks, but it is also easier to identify the patient's symptoms.

"No, I'll let Xiao Guo check. Zhou Jun nodded, "What other checks do you have to do?"

"I want to talk to the patient's family. Sun Lien frowned, he didn't actually have any other thoughts. It's just that the status bar has a helpful help at the moment, and he really doesn't have any other tests to do until it is confirmed by cerebrospinal fluid. After all, the patient's vital signs are stable and he didn't see anything on the imaging test five and a half hours ago. Even if there is a change in the condition, it is unlikely to be life-threatening immediately.

If you continue to stay at the scene, you will have to face Zhou Jun's constant questioning. Sun Lien didn't want to roast himself on the fire. Choosing to communicate with family members now is the best way to avoid disasters.

"The family is in the small conference room, you can go straight over. Zhou Jun nodded, and communicated with the family to understand the patient's medical history, which is a routine method. But sometimes, due to anxiety or other factors, it is easy for family members to miss some important information in the first few conversations with the doctor. Talking multiple times helps the patient's family to calm down the anxious emotions, and the doctor is more likely to find some special places in the conversation.

Yang Jianqiang came to the hospital with his wife. Yang Jianqiang himself is an ordinary programmer. Due to the special nature of the work, although I usually live in Ningyuan, the company I work for is far away in Shanghai. And Mrs. Yang is an authentic Shanghai woman. She used to be the leader of Yang Jianqiang, and she gradually attracted this science and engineering man with no hair but great humor at work. In the end, he did not hesitate to give up his management position and followed Yang Jianqiang to settle in Ningyuan.

However, this woman, who usually pays attention to her appearance, now has oily and messy hair, her face is full of acne, and the bags under her eyes are deep and large, and she looks like she is almost forty or fifty years old.

"Doctor......" When Mrs. Yang saw Sun Lien coming over, she immediately stood up from her seat nervously. "Old Yang...... How is he?"

"The situation is fairly stable. However, we are still trying other diagnostic options. Sun Lien pointed to his seat and motioned for Mrs. Yang to sit down first. "Don't worry, I have some questions for you. ”

Mrs. Yang was anxious, "Our old Yang has been sent to the hospital for a day and a night, why haven't you figured out what disease he has!"

That's why I'm asking questions. "He has received a bone marrow transplant before, and he has been using immunosuppressants to prevent the bone marrow from being attacked by the immune system. Sun Lien glanced at Mrs. Yang, "You know this thing, right?"

Madame Yang nodded, then began to cover her face and cry.

"Based on what you've described earlier, I still have some questions to ask. These questions may be related to your husband's condition. Sun Lien sighed, although he wanted to comfort the family in front of him, he had to finish the interrogation as soon as possible. It won't take long for Xiao Guo to do a cerebrospinal fluid pressure level test, and when the results are found to be abnormal, he is ready to send the patient to the imaging department for examination immediately.

Mrs. Yang tried to calm herself down, and she nodded to Sun Lien with red eyes, "You ask." ”

"The patient reports that he had a fever a week ago and that he was also showing signs of fatigue. Sun Lien looked at the case and racked his brains to think about the question, "Before this week, did he have any special injuries, he had difficulty moving, and he began to become forgetful...... Anything that is different from the usual will do. ”

Mrs. Yang lowered her head and began to try to remember what unusual experience her husband had had before. But no matter how hard she tried, she couldn't provide even the slightest hint of suspicious information.

"It's okay, it's okay if you can't think of it. Sun Lien had to stop asking again, and instead comforted the family. The main difficulty of diagnosis of Yang Jianqiang, a patient, is actually reflected here. In the existing testing system, most of the tests need to rely on the body's own immune system to respond to and label antigens. This is also known as an antibody test. It has to be said that the immune system in the human body is actually a very efficient and sensitive defense system. They produce specific antibodies against various antigens and use these antibodies to label the antigen to induce immune cells to destroy the antigen.

In modern medicine, doctors can use these antibodies floating in the blood to determine what is invading the human body and what is causing the disease. The antigen is identified by checking for antibodies, and the appropriate treatment is used by identifying the antigen. This is the basic treatment process of modern medicine.

However, this method did not work as it should have worked in Yang Jianqiang.

Immunosuppressants suppressed the cellular immune function in his body, and Yang Jianqiang was also treated with T lymphocyte depleting agents after bone marrow transplantation. This further weakened his body's immune system's ability to resist and label antigens.

Yang's immune system is unable to defend against antigens, and at the same time, it is unable to label them. This meant that not only was his body defenseless, but doctors had no way to help him — doctors had yet to figure out what was causing Mr. Yang's symptoms.

"That's it......" Sun Lien comforted him for a while, and after seeing that the effect of the comfort was not obvious, he suddenly had an idea. "Can you tell me about Yang Jianqiang?"

"What" Mrs. Yang was stunned, she thought she had misheard.

"Can you tell me what kind of person Yang Jianqiang is" Sun Lien took out the notebook and pen, "Please tell me what you know about him, you can start anywhere." He looked up at Mrs. Yang and said seriously, "Please say, I'm ready." ”

Yang Jianqiang is a technophile who loves life. This is Mrs. Yang's evaluation of her husband. He is humorous, kind, generous and has an immense zest for life. He likes to make his own furniture, repair his own appliances, and even graft cuttings for his own fruit trees – even if he has no experience or knowledge of the subject.

The Yang family is full of Yang Jianqiang's homemade handmade works, and the types are also different. From the homemade sofa, to the homemade wool felt, and even the cat climbing frame in the ceiling in the corner of the Yang family, Yang Jianqiang made it little by little.

"You have pets at home" Sun Lien suddenly perked up when he heard this, which was not mentioned in the previous medical records.

"Nope. Mrs. Yang shook her head a little lonely, "Old Yang wants to raise a cat, so before decorating the house, he has already designed these cat climbing frames and other things." But we were going to have a baby, so we never raised it. ”

"I don't have a pet...... Sun Lien's excitement went down, but he still pulled himself up and asked, "How long have you been preparing to get pregnant?" Mrs. Yang and Yang Jianqiang are not too young.

"More than two years. Mrs. Yang lowered her head, "We went to the hospital for a check-up, and I had some difficulty getting into bed." ”

In other words, Yang Jianqiang did not have any problems with the reproductive system before. Sun Lien once again ruled out a direction. However, none of this seems to be directly helpful in diagnosis.

"I'm still a little concerned about the cat climbing frame. Sun Lien pondered for a while, and asked directly, "When doing carpentry and the like, does he use any varnish or spray to protect the wood?"

Mrs. Yang shook her head, "We stayed away from all the chemicals we could when we were trying to get pregnant. Lao Yang's carpentry never uses varnish, and if he needs to be preserved, he will use a spray gun to bake it on the wood to make it carbonized and antiseptic. ”

"Why is it a cat climbing frame" Sun Lien continued to ask, anyway, there is no purpose, maybe if you continue to ask like this, you can ask for some clues. "Did he ever have a cat before?"

"Before I knew each other...... Lao Yang should have had a dog. After trying to recall for a while, Mrs. Yang replied uncertainly, "It's just that before he went to Shanghai to apply for a job, the dog was run over by a car and died." Not...... He said his grandmother used to have a white cat. A big white cat with blue eyes, very beautiful. It's just that it was almost 30 years ago. ”

There seemed to be nothing suspicious Sun Lien sighed, it seems that this conversation has not made much progress. I don't know how Xiao Guo's inspection is.

"Brother Sun. Just pondering, Xiao Guo suddenly poked his head out of the rescue room and beckoned to Sun Lien, "The cerebrospinal fluid pressure is 210mm/h2o, a little higher." ”

"Send it to the CT room and do another MRI. Sun Lien stood up from his seat suddenly, "Prepare two bags of mannitol...... "Something suddenly remembered, "What about Dr. Pascal"

"Lao Pa should be out of the clinic today on the rheumatism side. Xiao Guo replied, "Do you want me to call him over?"

"No, you go and arrange the imaging work. I'm going to ask Lao Pa to come over and press the formation. Sun Lien quickly made arrangements, and after saying sorry to Mrs. Yang, he rushed directly to the side of the duty desk.
