"Let's get straight to the point. Why did I say it's the most important step? It's because the most common way is to die in public. Of course, this is referring to online chatting. If she sees your face and can still keep the appointment, it's more likely to work. "
"…" Zheng Ren really wanted to kill this guy.
"Don't be nervous when you meet her. Just chat and say something to make her happy," Su Yun continued, "After that, it's the most important step — the second invitation. If you can ask her out a second time, it means there's no problem. As long as you don't do anything stupid, it should work. "
"Uh …" Zhou Litao looked at the record on the A4 paper, wrinkles appearing on his forehead.
"That's basically it. Understand the spirit and learn well."
"Brother Yun, err …"
"Chief Zhou, there's something wrong with the patient!" A nurse knocked on the door.
"Okay, I'll go right away." Zhou Litao's conflicted and distressed expression immediately disappeared, replaced by an extremely focused and serious expression. He folded the paper that recorded Su Yun's words and put it away.
"Brother Yun, Chief Zheng, please wait for a moment."
"What patient?" Zheng Ren asked.
"A patient who suddenly lost his sense of smell," Zhou Litao said. "I asked him to do a cranial CT scan."
"Oh, go ahead." Zheng Ren knew that the patient's medical history was probably fine and was too lazy to look at it.
The ability to smell was a characteristic of the olfactory cells in the nasal mucosa. Damage to the nasal mucosa, olfactory bulb, olfactory filament, or central nervous system could affect the sense of smell.
Clinical manifestations included decreased sense of smell, loss of smell, anosmia, anosmia, hallucinations, and increased sensitivity to olfactory stimuli.
There were many common causes of loss of smell.
These included allergic sinusitis, nasal polyps, cold virus infection, rhinitis virus infection, head trauma, sulfur dioxide, nitride, and residual indoor formaldehyde after renovations.
Moreover, long-term perfume could also cause the loss of smell.
Zheng Ren wondered what caused the patient's condition. It could be due to formaldehyde. Excessive formaldehyde was a common factor in home renovations.
Zhou Litao immediately ran out.
"Boss, I'm a professional, right?" Su Yun said with a smile.
"I think only Zhou Litao would believe this," Zheng Ren said. "You don't even have a girlfriend. How dare you say this?"
"Tsk!" Su Yun said: "I don't want to find it, okay? There are plenty of girls. Find a girlfriend on the street! "
Zheng Ren could not be bothered with him. It was boring waiting for Zhou Litao to return. He did not know how long it had been, and there was a chatterbox sitting next to him who would occasionally say a few words. He could not even go to the System library to read books even if he wanted to.
He waited for a long time, but Zhou Litao did not return, which was strange.
He was really bored, so he stood up and pushed the door open.
Noticing a busy nurse in the corridor, Zheng Ren asked, "May I know where Chief Zhou is?"
"Teacher, I just got here. I don't know who Director Zhou is. I'm sorry," the nurse immediately replied.
Oh, it was the nurse who had just come to the 912 for further training. Zheng Ren smiled.
Su Yun saw that the nurse had entered the treatment room. She was probably going to change the dressing, so he smiled and said, "I'll go ask."
Zheng Ren glanced at him and saw that the guy had turned around to go to the treatment room. He leaned against the door frame and began to talk and laugh as if he had no bones.
'He really knows me,' Zheng Ren thought to himself.
However, it was quite troublesome for him to ask a question. After waiting for a few minutes, Su Yun returned with a face full of pride.
"Where is he?"
"He said that the patient with a problem with his sense of smell just now went to the CT room and got a draw," Su Yun said.
"Got a draw?" Zheng Ren was puzzled. "Is it epilepsy or spasms?"
"No one saw it. Why are you asking in so much detail?" Su Yun said. "You'll know when Chief Zhou comes back."
"Where's Zhou Litao?" Zheng Ren was puzzled.
"He said it was an emergency rescue. The draw was very severe. There's no way to do a CT scan at all."
The CT image was full of artifacts. It was the same as not doing it.
This patient should probably be sent to the neurology department. There was nothing to be done in the CT room. If the patient's breathing and circulation suddenly stopped, he would have to die.
However, the patient with a problem with his sense of smell suddenly twitched …
There was something wrong with this medical history.
Zheng Ren began to think.
"Boss, if you can make a diagnosis now, I'll be convinced," Su Yun said with a smile.
Zheng Ren also knew what he meant. He knew that the patient's sense of smell had failed and he had gone to the CT room to twitch. It was impossible to make a deduction based on these two points.
However, since he had nothing to do, Zheng Ren returned to the room and sat down. He began to count with his fingers.
"First, when the patient has cranial trauma, the olfactory filaments of the olfactory nerve through the cribriform plate can be torn, or the olfactory bulb can be torn because of contusion."
Su Yun looked at his serious expression and found it interesting. He sat opposite him and said, "From a logical analysis, the patient is not injured. Otherwise, with Zhou Litao's personality, he would definitely say that the sense of smell failed after the injury."
Zheng Ren nodded. Su Yun's judgment was right.
"Second, meningiomas, metastases, or infiltrating tumors in the anterior fossa artery or frontal lobe can oppress the olfactory bulb and olfactory tract, causing damage to the sense of smell."
"This is also unreliable. If there is a meningioma, the sense of smell failure will not be the main complaint. Moreover, if the patient does not know, generally speaking, there will not be sudden convulsions, "Su Yun said.
"You can't say that. It's just a high probability. This is doubtful," Zheng Ren said. "The probability is about five percent."
"More or less. I think it's a little less. Continue." Su Yun was very interested in this kind of case discussion.
"Third, the sense of smell caused by influenza is temporary, and there is basically no convulsion. This is also ruled out."
"Fourth, occasionally, temporal lobe lesions are accompanied by temporary or paroxysmal hallucinations. Loss of smell is often accompanied by taste damage, depending on the volatile substances in the food and drink. "
"Temporal lobe symptoms?" Su Yun asked.
"It's just that it should not be a symptom of temporal lobe symptoms," Zheng Ren said. "Volatile substances can cause the sense of smell to fail, but convulsions and the need for rescue are too ridiculous, so we can't consider it for now."
Su Yun increasingly felt that this kind of diagnosis and differential diagnosis was very interesting. It was like playing a game of intelligence.
"Fifth, congenital factors can't be considered. Then there is the nasal mucosa, olfactory bulb, and olfactory filament neuropathy, which causes a decline or loss of olfactory function. As for the central nervous system connection damage, there is usually no detectable loss of smell."
"Is the possibility of the fifth point high?"
"It's hard to say. It's probably not high because there are no convulsions at the same time."
"After talking for so long, do you have a diagnosis? The biggest possibility is an intracranial tumor. The probability is less than five percent, "Su Yun said.
