On the side of the hospital bed, Cao Yanhua is still adjusting the medication. But Sun Lien's expression was already a little wrong. Xu Yourong asked curiously, "What's the matter?"

"Recognize. Sun Lien nodded and said with difficulty, "She's my college roommate's girlfriend." As he spoke, he took out the phone, found the number of the "dormitory second" from the address book, and quickly dialed it.

"Hey, the third child, hurry up and say something. Feng Ming on the other end of the phone seemed to be in a good mood, "Today is Xiaoya's birthday, and I plan to take her to watch a movie." Come to my room and eat cake together in the evening. ”

Sun Lien's heart tightened, he let out a long breath, tried to calm his tone, and said in a deep voice, "Qin Ya is in the rescue room, her parents sent it." ”

Feng Ming's voice on the other end of the phone suddenly changed, "My day, third child, this joke is not funny." ”

"I also hope it's just a joke that isn't funny. Sun Lien sighed, "Let's take a look." My instructor suspected that there might be a cerebral hemorrhage and was ready for me to take over with Dr. Xu. ”

"Well, at least certainly, not carbon monoxide poisoning. Dr. Cao Yanhua shook his head and looked at the checklist in his hand, "The carboxyhemoglobin content is normal. ”

Sun Lien came over and looked at the checklist with Cao Yanhua. All indicators were normal, which means that several of the more common causes of sudden fainting, including carbon monoxide poisoning and viral/bacterial meningitis, have been ruled out.

Cao Yanhua sighed and said to Sun Lien, "I have asked the nurse to prepare mannitol, it seems that this case is going to be handed over to you." ”

Sun Lien nodded, and began to ask Qin Ya's parents, who were standing beside the bed with anxious expressions.

"Has she ever had symptoms such as dizziness, fatigue, and numbness in her limbs before?" Compared with Cao Yanhua, who didn't know anything, Sun Lien's biggest advantage was the prompt in the status bar. Transient cerebral ischemia can be a symptom that can be large or small. At worst, it could be a carotid embolism or even a heart attack. At worst, it may just be anemia. "Did she say she's been feeling unwell lately?"

After Qin Ya's parents glanced at each other, they shook their heads together, "No." This child is usually in good health, not to mention any numbness, even headache and brain fever have not happened in recent years. ”

Sun Lien asked about the medical history while watching the nurse come to give Qin Ya an infusion, no matter what, the benefits of infusion mannitol first definitely outweighed the risks.

I was asking for my medical history when suddenly the door to the emergency room was pushed open. Feng Ming, who was usually very arrogant, rushed in with a cold wind. At a glance, he saw Sun Lien, who was asking about his medical history, and his "future" father-in-law and mother-in-law who were standing beside Sun Lien with an anxious face.

"What's going on?" Feng Ming looked more anxious now than ordinary family members. Xu Yourong's reputation in neurosurgery was heard of even by Feng Ming. As soon as he thought that his girlfriend was going to be handed over to Xu Yourong to take over, Feng Ming felt a little nervous from the bottom of his heart.

Father Qin seemed to see a savior after seeing Feng Ming, "Xiao Feng, you came just in time." You've been spending a lot of time with Xiaoya lately, so come and talk to the doctor about the situation. ”

Feng Ming didn't shy away from it, he directly picked up the case record placed at the foot of the bed and looked at it, and said while reading, "Xiaoya has a history of allergies, and she is allergic to mangoes and lemons." ”

"Are there any drug allergies?" Allergy history may be a very important medical history, but it is unlikely to cause Qin Ya to suddenly faint while taking a bath. Out of caution, Sun Lien still asked more.

"Nope. Feng Ming shook his head, looked at his girlfriend on the hospital bed with crimson cheeks, and said, "She had persistent diarrhea a month ago, which lasted for about a week. By the way, she said that there are always wheals after the cold wind blowing on her neck recently. ”

Xu Yourong suddenly asked, "Wheals?" she looked at Sun Lien and asked, "The manifestations of urticaria, coupled with diarrhea and allergies, may be systemic lupus erythematosus." ”

Although a neurosurgeon, Xu Yourong still has a high sensitivity to autoimmune diseases. As the most severe of all lupus erythematosus, systemic lupus erythematosus is generally accompanied by multi-organ damage. And 24-year-old Qin Ya is indeed a high-risk group of systemic lupus erythematosus - women, young people.

Sun quickly recalled in his mind the cases the professors had told him in class. The immune system in the human body reduces the number of immune T cells in the body under the combined action of various conditions, while inhibiting the activity of the remaining immune T cells, while at the same time there is a large number of immune B cells proliferating. After immune B cells proliferate, they mistakenly secrete a large number of autoantibodies. These antibodies identify normal human tissue as invaders and combine with normal tissues to form immune complexes. Finally, under the action of complement serum protein C3, acute and chronic inflammatory responses are induced. In severe cases, tissue necrosis may even occur.

If some normal tissues in the walls of Qin Ya's cerebral arteries are mislabeled as antigens by B cells, then it is indeed possible for these blood vessels to produce an inflammatory response under the attack of the immune system, thus causing tissue proliferation in the blood vessel wall. Under hyperplasia, the increasingly narrow walls of blood vessels naturally cannot allow enough blood to pass through. This caused Qin Ya's fainting, as well as the transient cerebral ischemia suggested by the status bar.

"Consistent with the symptoms. Sun Lien nodded, and he also agreed with Xu Yourong's judgment, "Do a rheumatism five tests to clarify." But out of caution about the symptoms of "sudden syncope", Sun Lien continued, "After the nurse collects blood, it will be sent to the CT room immediately, and the cerebral hemorrhage must be ruled out to rest assured." ”

Qin Ya's parents couldn't understand what the young doctor in front of them was saying at all. Father Qin gently tugged at the clothes of his future son-in-law Feng Ming, "Xiao Feng, what do you mean by doctor?"

Feng Ming was already a little relieved after hearing Xu Yourong's judgment. Systemic lupus erythematosus is dangerous, but it is not incurable. Treatment for systemic lupus erythematosus requires hormones to suppress the immune system response than neurosurgery, which is very risky. And the sequelae are much lighter.

"Uncle Qin, the doctor suspects that Xiaoya has an autoimmune disease. Feng Ming explained in a low voice, "It means that there is something wrong with the army that Xiaoya uses to remove bacteria in her body, and she treats good cells as bacteria." ”

"Huh?" Qin Mu was a little at a loss, "What can I do about this?"

"Rest assured, the disease is not very serious. Feng Ming hurriedly comforted, "It's a big deal, just get a few injections, it's okay." ”

Feng Ming comforted his future mother-in-law here, but Sun Lien coughed, meaning to ask Feng Ming not to talk too much, "We still need to do some other tests to rule out other diseases." In particular, the most dangerous intracerebral hemorrhage should be ruled out first. ”

Feng Ming glared at Sun Lien with some unhappiness, and the meaning in his eyes was also very clear, "In front of my girlfriend's parents, can't you pay attention to the words?"
