"The patient does not have coronary heart disease!" Su Yun said habitually.
But he moved slightly, but sat down firmly. He didn't get out of the car, but looked at Zheng Ren's back, thoughtfully.
"Brother Yun, what is Boss Zheng doing?" Luan Yingjie asked anxiously, already confused.
"You're buying medicine, why don't you go to the drugstore to buy vegetables? Don't tell me, some people go to the hospital to buy barley. Maybe the drugstore also sells vegetables." Su Yun's answer was not serious at all.
"..." Luan Yingjie didn't know how to answer for a moment.
"Brother Yun, are you saying that if I don't send my dad to a mental hospital, will his illness get worse? How about I move to a courtyard house? I'm really afraid that one day he will lose his mind and jump off the building." Luan Yingjie Said in distress.
"Hey, Lao Luan, you've made a lot of money these years, and you still have a courtyard." Su Yun saw Zheng Ren walking into the drugstore and started chatting with Luan Yingjie.
"Isn't my old house waiting to be demolished? But we also say that we need to protect cultural relics. What's the point of protecting an old house?" Luan Yingjie said, "We will have to sort the garbage again in a while. I …”
"Why are you involved in garbage sorting again?" Su Yun said: "It's okay. I think the boss's expression means it's nothing serious. Don't worry."
"Brother Yun, there is a rumor in Pengcheng that Boss Zheng cured an Earth Master of all his curses. Is this true?" Although Luan Yingjie was anxious, he couldn't leave at this time, so he had to talk to Su Yun is talking nonsense.
"What a master, he's just a bathhouse owner." Su Yun smiled and said, "Don't talk nonsense like this feudal superstition."
"Uh..." Luan Yingjie was startled for a moment, thinking that Brother Yun was still young and bold, and the Earth Master became a rub in his mouth.
Soon, Zheng Ren came out of the point and returned to the car.
"The price of nitroglycerin has increased." This was the first thing Zheng Ren said after getting in the car.
Su Yun was surprised.
Doctor, who has nothing to do and goes to the pharmacy to buy medicine? Now there is zero markup on medicines in hospitals, and medicines are cheaper than in pharmacies. Apart from having to queue up and register, there are no other disadvantages.
The price increase of nitroglycerin has no impact at all on my own boss, okay
"How much has it increased?"
"10 times? 20 times?" Zheng Ren said.
"..." Su Yun didn't know much about this and was suddenly shocked.
"Nitroglycerin used to be in a big bottle, and I didn't know how many pills were in it. Sometimes patients were asked to go to the pharmacy to buy it themselves." Zheng Rendao, "Now the big bottles are no longer cheap, and only this kind of well-packaged ones are left. .Packaging accounts for 95% of the retail price, tell me..."
"Stop talking nonsense and get down to business." Su Yundao said, "Why did you buy nitroglycerin?"
"Do a tilt test." Zheng Ren said.
"Tilt test? Is it to see if my dad's brain works well or not? Or is his body flexible?" Luan Yingjie asked, "Boss Zheng, what you just mentioned is mental..."
"It's autonomic nerves, not mental illness." Zheng Ren corrected, "Now that I think it's not a mental illness, don't talk nonsense."
Why does Boss Zheng speak as if he is his own son, while he is a bystander
Luan Yingjie was a little surprised.
"The patient's upright reaction is similar to actual clinical syncope, so it is used to assist in the diagnosis of vasovagal syncope. Is this it?" Su Yun asked.
"Um."
"Then why are we following?" Su Yun was confused.
"Take a look, and in order to increase the effect of the tilt test, I took nitroglycerin orally, and the symptoms will be more obvious." Zheng Ren said, "I'm worried that the old man will have a temporary discomfort that cannot be dealt with at home."
"You don't have anything." Su Yun said.
"Call 120 for first aid?" Zheng Ren said, "Let Zhou Litao come directly with the first aid kit. If anything happens, we can handle it immediately."
"Are you using this as a public weapon for private use?" Su Yun spat.
"Patients, as long as resources are used on patients, it doesn't count." Zheng Rendao, "If I drive the 120 ambulance out to play, it is considered a public tool for private use."
"Don't mention it yet. I heard from the teacher that when he went to knife throwing in the past twenty years, the local hospital drove a 120 ambulance to take him out for fun." Su Yun said with a smile.
"It's gone now. Even the 120 emergency department can't get here." Zheng Ren said.
Luan Yingjie felt a little anxious when he heard the two chatting here. He took the time to interrupt the conversation and asked: "Boss Zheng, what is the tilt test?"
"Uh..." Zheng Ren thought for a while. It was very troublesome to explain, but when the patient's family members asked, he couldn't say nothing.
Let’s talk about the tilt test after taking nitroglycerin. There are still some fluctuations, and the patient’s family members need to cooperate.
"Let's put it this way, Boss Luan." Zheng Ren said: "When the human body is upright, 300~800ml of blood accumulates in the lower limbs due to gravity, causing central venous pressure, stroke volume and arterial blood pressure to decrease, and reflexively causing sympathetic nerve tension Elevated, manifested as increased heart rate, slight decrease in systolic blood pressure, and slight increase in diastolic blood pressure.”
Seeing Luan Yingjie's confused look, Su Yun interrupted Zheng Ren and said, "Do you have any friends with high blood pressure?"
"Yes, I have."
"The first thing I do when I get up every morning is take my blood pressure. I lie down on my back on my bed because my blood pressure is unstable when I stand. That's what the boss just said."
Well, explain it in human terms, Luan Yingjie will understand immediately.
Su Yun was also helpless. The boss must be looking forward to doing the test right away. His explanation was too professional.
"Well, that's basically it. I think your father has autonomic nervous system problems." Zheng Ren continued: "Patients with vasovagal syncope have more blood accumulation in the lower limbs when standing upright than normal people. The central venous pressure decreases significantly, and the amount of blood returned to the heart increases. decreases, and sympathetic tone continues to increase.”
Luan Yingjie half understood what he heard.
"This then leads to a significant increase in ventricular contractility and over-stimulation of the baroreceptors on the posterior and inferior walls of the left ventricle, which reflexively causes a decrease in sympathetic tone, vasodilation, a drop in blood pressure, sudden ischemia of the brain, and syncope, sometimes accompanied by vagal tone. Increased, bradycardia.”
"Boss, have you done any research on unmyelinated C nerve fibers?" Su Yun suddenly asked.
"Have you done research? Using mice in the laboratory?"
"Well, that's interesting." Su Yun said with a proud smile, "I'll cut off..."
Next, Luan Yingjie listened to Su Yun's story about cutting off the unmyelinated C nerve fibers of mice in the laboratory as if they were reading from heaven.
20 minutes later, the car drove home. Zheng Ren got out of the car and made a phone call.
He first called Zhou Litao and asked if the other side was busy, and then told the situation on his side.
Zhou Litao was so interested. He felt that Boss Zheng was so generous. He would not forget to ask him to come out and take a look when he encountered a patient who fainted after eating.
