It's not an infection, it's not an autoimmune disease, it's not organic compound poisoning. Sun Lien hugged Hu Jia in a circle, he was so happy.

"Should I wait outside for a while before coming in?" Dr. Pascal asked, half-leaning against the door frame, looking at Sun Lien and Hu Jia with a smile, "Why are you so happy all of a sudden?"

"I can figure out what kind of illness Zhan Hao has!" Sun Lien said to Dr. Pascal, "It's not an autoimmune disease, it's poisoning, heavy metal poisoning!"

Heavy metal poisoning refers to poisoning caused by heavy metal elements or their compounds with a relative atomic weight greater than 65. Because heavy metals can irreversibly change the properties of protein surfaces, heavy metal poisoning often manifests as hemolysis, smooth muscle spasms, and neurological symptoms. Since the liver and kidney are the most important metabolic and detoxification organs in the human body, heavy metal poisoning can also seriously affect the health of the liver and kidney, and even cause symptoms such as organ failure in severe cases.

"Can explain all his symptoms. Dr. Pascal thought for a moment and nodded, then shook his head again, "But he doesn't have a way to get involved." ”

"I'll call everyone back first, Xiao Guo! Open a urine test to check for lead in the urine!" Sun Lien didn't ask the patient how he ingested lead. The second half of the sentence was shouted at nurse Xiao Guo.

A few calls called back Xu Yourong and Yuan Ping'an, who hadn't had time to wash their hair, and even Liu Pingchuan was invited to the conference room by Sun Lien. The urine sample had been sent to the laboratory for testing, and he explained his diagnosis to many members of the treatment team. Hu Jia found a vacant seat to sit down and quietly enjoy her boyfriend's performance.

"There is no explanation for his symptoms other than heavy metal poisoning. Sun Lien explained his diagnosis to the team members, "From the perspective of symptoms, the most consistent manifestation is acute lead poisoning, and I have asked Xiao Guo to send a sample for testing, and the result should be available soon." ”

Liu Pingchuan frowned and knocked on the table, "You also said that it was acute poisoning." Whose acute poisoning manifests itself as having an onset nine days ago, then resolves on its own, and then recurs nine days later?"

"In the case of fat-soluble compound poisoning, it may increase gradually due to nutrient intake. I have heard of cases of fat-soluble allergies, even in the clean room of the hospital, which still cannot prevent the continuous appearance of allergies in the blood that are absorbed and stored by fat cells. Later, he reluctantly stopped relying on high-calorie foods, and he continued to consume fat. But that's a constant deterioration, and there's no fluctuation like this in between. "He was brought to us from another hospital, and it was about 30 minutes on the way, and it was probably a little cold after getting in and out of the car. But I don't think thirty minutes of jolting and a brief moment of cold might cause a re-outbreak of a disease that has been relieved – even if it is heavy metal poisoning. ”

"On top of that, this patient's profession is retail. He opened his own small supermarket. It's not a smelting or metalworking industry, nor is it a heavily polluting industry like batteries. The amount of acute lead poisoning that needs to be ingested at one time is significant. There has not been a single case of acute lead poisoning in our city in the past five years, and there have been few cases of chronic lead. Xu Yourong also disagreed with Sun Lien's diagnosis, "Even if he is really poisoned, it is obvious that he is hospitalized in the hospital, even if he leaves the toxic substance." In this case, he will not have another acute attack in nine days. ”

Sun Lien's diagnosis was often questioned by other doctors because of the precept, but at those times Sun Lien was very confident - how could the results of the precept be wrong? But this time it was different, this time the diagnosis was completely based on Sun Lien's own inference. The information provided by the status bar is actually very limited, and it does not even go beyond the existing test results.

Therefore, Sun Lien is a little empty.

But the content he deduced, Sun Lien understands the logical laws best. Indeed, a diagnosis of illness is the same as detective reasoning, when you rule out all other possibilities based on available intelligence and evidence, the remaining answer, no matter how implausible, is the correct answer.

The patient's condition and blood test results do not match any known infection or autoimmune disease. Zhan Hao was either poisoned by heavy metals and ingested the poison again within nine days, or he was suffering from some unknown disease.

The second scenario is not completely impossible, but the first is obviously more likely.

"Anyway, we'll know when the lead results come out. Completely relying on himself to make the diagnosis, Sun Lien is full of confidence at the moment.

Yuan Ping'an suddenly laughed, "Don't say it, if it's really heavy metal poisoning, you may be the only one in this room who is most likely to be diagnosed." ”

"Why?" The atmosphere in the room eased, and Hu Jia couldn't help but ask. Although she and Xu Yourong are quite familiar, watching a group of doctors keep denying Sun Lien's diagnosis, she feels a little unhappy in her heart. Now hearing Yuan Ping'an's approval, Hu Jia suddenly became curious.

"Heavy metal poisoning is not included in the scope of diagnosis and treatment in our ordinary hospitals. Especially the lead poisoning he was looking for. Yuan Ping'an replied, "If you are not a medical student in public medicine and occupational disease prevention, you can be exposed to the concept of 'lead poisoning' when you are in the third year of public health courses." To put it bluntly, among the doctors present, Sun Lien can still clearly remember this disease. If he hadn't thought of it, we'd probably have to work for a long time to think about it. ”

"Actually, that's not what I thought of. Sun Lien explained with a smile, "Hu Jia and I mentioned the matter of the coating of the thermal insulation tableware falling off, and I thought of this aspect." Didn't it often be said that peeling off the coating would cause poisoning? The doctor in the laboratory department also mentioned to me that the patient's blood sample had a large number of basophilic stippling red blood cells under the microscope. The appearance of a large number of basophilic stippling red blood cells is likely to be caused by heavy metal poisoning. ”

"If it is poisoning, you must find out whether it was accidentally ingested in his usual life, or whether there was poisoning. Liu Pingchuan made a decision, "The patient is still conscious now, and his family seems to be in the hospital." Lien, you go and ask about the situation, and if necessary, notify Lao Wu to come over. ”

Hu Jia and Sun Lien walked out of the conference room together, and after the two of them were a little tired for a minute or two, Hu Jia waved her hand at Sun Lien, she had to go back to rest. And Sun Lien walked to Zhan Hao's side with a strange sense of satisfaction of successfully performing in front of his girlfriend.

"Dr. Sun. Zhan Hao still looks very weak, but his spirit is okay. "I'm really bothering you this time. ”

"That's what we're supposed to do. Sun Lien pulled out a stool and sat down on the side of Zhan Hao's bed, "I have some questions for you about the cause of your illness. Please try to answer truthfully, and if you don't remember or can't answer well, tell me the reason. ”

Zhan Hao smiled bitterly and nodded, "In more than a week, I died of pain twice. I don't want to have a third time in my life. You ask, and I promise to say anything. ”

"Before your first illness, did you do anything related to metal smelting, or went into a place that used to be a factory or something?" asked Sun Lien from the simplest place. The most common cause of heavy metal poisoning is the air, metal dust may enter the alveoli through the respiratory tract and enter the bloodstream during the gas exchange in the alveoli.

"No, there's no such place near my house. Zhan Hao shook his head lightly and asked with some concern, "Doctor, I have been feeling that my eyes can't see things clearly recently......

"Vision problems should also be related to your condition. "We need to determine the cause of your illness before we can deal with it in a targeted manner." "Demyelinating lesions are actually very difficult to continue treating – the damage it causes is almost irreversible. But if it can be diagnosed as soon as possible and treatment can begin, Zhan Hao's vision still has a certain chance of recovering - but the extent of recovery is not easy to say. Therefore, Sun Lien did not say anything to death, now is not a good time to increase the psychological burden of patients. "During this time, have you taken any home remedies or any traditional Chinese medicine to regulate your body?" For example, medicinal materials such as lead powder, lead pill, yellow pill, tantric monk, and Chinese patent medicine such as Erwei Black Xidan will contain a lot of lead. Sometimes, drug-induced lead poisoning can be caused by a mistake in the pharmacy or a doctor's prescription that mismeasures the dosage of the drug.

"Nope. Zhan Hao continued to shake his head, "My brother works in medical school, and he usually talks to me about what is a medicine that is poisonous, even if it is a Chinese medicine. What's more, I haven't felt anything uncomfortable lately, what are you doing with Chinese medicine?"

"Then have you eaten any food that you have never tried before?or drinks, medicinal wine?" Sun Lien continued, he was a little panicked, there must be a way of contact for poisoning. Without a way of contact, could it be that this poisonous substance fell from the sky and then fell into Zhan Hao's mouth?

"No ......" Zhan Hao wanted to deny this question, but suddenly frowned, "The neighbor of my hometown came to Ningyuan a few days ago and brought me some bacon and other things, I ate it and it tasted good." ”

Sun Lien suddenly came to his senses, "Bacon, how much did you eat last time, have you eaten it recently?"

"Last time...... Last time, it seemed that after eating, my stomach started to hurt the next day. Zhan Hao also realized that there was a problem here, "And the day before yesterday, I asked my brother to go back and fry the remaining half of the bacon for two dishes." He said that he liked to eat this meat, so he gave me all the dishes. ”

Bacon, then there must be something wrong with bacon! Sun Lien suppressed the excitement in his heart, and gently patted Zhan Hao's shoulder, letting him rest well. Then he walked out of the rescue room quickly, and dragged the soldiers who were sitting at the door napping. "Brother Zhan, is there any leftover of the bacon that your brother ate before?"

"Yes. Zhan Jun nodded, not knowing why Sun Lien suddenly asked this question, "What's wrong?"

"Is it in your shop?" This question was answered affirmatively by the war army, and Sun Lien hurriedly said, "You go back immediately and take a look at this piece of bacon." I'll call the police right now and have the police go and pick up ...... No, you're waiting for me here. I'm going to call Lao Wu over. ”

The soldiers were stunned for a moment, "What's the matter, why is there still a police business?"

"There may be something wrong with that piece of bacon, someone is planning to harm your brother!" Sun Lien ran back again, whispered a sentence in the ear of the war army, and then left a sentence, "Wait for me here", and then ran to the police station with a puff of smoke.

"Lao Wu, I have sent you a big case!" Sun Lien pushed open the door of the police station and shouted to Lao Wu, who was making instant noodles in the room, "Hurry up and call a few colleagues from the criminal investigation to come with me and go to Ningyuan Medical College!"
