"The patient has no coronary heart disease!" Su Yun said habitually.

But he moved slightly, but sat down steadily. He did not get out of the car, but looked at Zheng Ren's back, thinking.

"Brother Yun, what is Boss Zheng doing?" Luan Yingjie was already confused and asked anxiously.

"You buy medicine, can you buy vegetables when you go to a pharmacy? You really don't know. If you buy coix seed in the hospital, maybe the pharmacy 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, if you say I don't send my dad to a mental hospital, will his illness be worse? Why don't I change to a hospital in a quadrangle? I'm really afraid that he will jump from the upstairs one day." Luan Yingjie said distressedly.

"Oh, Lao Luan, I've earned a lot over the years, and I have a courtyard house." Su Yun saw Zheng Ren walk into the pharmacy and started to fight Luan Yingjie.

"Isn't my old house waiting for demolition? But I said I should protect cultural relics. You said, what is the best way to protect an old house?" Luan Yingjie said, "I will sort garbage again after a while, I..."

"Why are you engaging in garbage sorting again?" Su Yun said: "It's okay, I see the boss's expression, there should be nothing big, don't worry."

"Brother Yun, the story in Pengcheng said that Boss Zheng had cured the heavenly punishment of a Earth Master. Is this really a matter?" Although Luan Yingjie was anxious, he couldn't leave at this time, so he had to talk nonsense with Su Yun.

"What kind of land master is just a bathhouse?" Su Yun smiled and said, "Don't talk nonsense about such feudal superstitions."

"Uh..." Luan Yingjie was stunned for a moment, thinking that Brother Yun was still young and brave, and the Earth Master turned into a bath in his mouth.

Soon, Zheng Ren came out of the key point and returned to the car.

"Nitroglycerin has increased." After Zheng Ren got in the car, the first sentence was actually this.

Su Yun was surprised.

Doctor, who can go to the pharmacy to buy medicine? Now hospitals have zero bonus for medicines, and drugs are cheaper than pharmacies. They have no other disadvantages except queuing up and registering.

The price increase of nitroglycerin has no effect on one's own boss.

"How much has it increased?"

"10 times? 20 times?" Zheng Ren said.

"..." Su Yun had no idea about this and was shocked.

"In the past, nitroglycerin was a big bottle. I don't know how many pieces of it are inside. Sometimes patients bought it at the pharmacy themselves." Zheng Ren said, "Now the big bottles are no longer cheap, only this kind of refined packaging is left. The packaging accounts for 95% of the retail price. Tell me..."

"Don't talk nonsense, just talk about serious things." Su Yun said, "What are you doing for buying nitroglycerin?"

"Do the tilt test." Zheng Ren said.

"Tilt test? Is it a way to see if my dad's brain is easy to use? Or is it a flexible body?" Luan Yingjie asked, "Boss Zheng, what you just mentioned..."

"It's the autonomic nerve, not the mental one." Zheng Ren corrected, "Now considering it is not a mental illness, don't talk nonsense."

Why does Boss Zheng speak the same attitude as his own son, but he is a person who is the other person?

Luan Yingjie was a little surprised.

"The patient's orthodontic reaction is similar to the actual clinical manifestations of syncope, so it is used to assist in the diagnosis of vaguscular syncope. Is this?" Su Yun asked.

"Um."

"Then what are we going to do?" Su Yun was puzzled.

"I took a look, and in order to increase the effect of the tilt test, taking nitroglycerin showed more obvious performance." Zheng Ren said, "I am worried that the old man will feel transient discomfort and cannot be handled by the family."

"You have nothing, either." Su Yun said.

"Call 120 for first aid?" Zheng Ren said, "Let Zhou Litao come here directly with a first aid kit. If there is really something wrong, it can be dealt with immediately."

"You are considered to be a public utility for personal use?" Su Yun squirted.

"As long as the resources are used on the patients, it is not considered a matter of this." Zheng Ren said, "If I drive a 120 ambulance out to play, it will be considered a matter of public use."

"You can't tell me, I heard from the teacher that he went to the flying knife in the first twenty years, and the local hospital drove a 120 ambulance out to play." Su Yun said with a smile.

"Now there is no more, and even 120 first aid can't escape." Zheng Ren said.

When Luan Yingjie heard the two chatting here, he felt a little anxious. He took the time to interrupt the conversation and asked: "Boss Zheng, what is the tilt test?"

"Uh..." Zheng Ren thought for a while, and it was very troublesome to explain, but the patient's family asked, and he could not say nothing.

Besides, taking nitroglycerin for a tilt test will be a little more disturbing, and the patient's family members will also need to cooperate.

"Let me say this, Boss Luan." Zheng Ren said: "When the human body is upright, due to gravity, 300 to 800 ml of blood accumulates in the lower limbs, causing central venous pressure, stroke output and arterial blood pressure to decrease, and reflexivity causes an increase in sympathetic nerve tone, which is manifested as an increase in heart rate, a slight decrease in systolic pressure, and a slight increase in diastolic pressure."

Seeing Luan Yingjie's confusion, Su Yun interrupted Zheng Ren and said, "My friend with high blood pressure, do you have any?"

"Yes, I have."

"The first thing you do when you wake up every morning is to take your blood pressure. Lying on the bed and lying flat is because your blood pressure is unstable when you stand. What the boss just said is what he meant."

Uh, if you explain it in human terms, Luan Yingjie will understand immediately.

Su Yun was also helpless. The boss should be looking forward to experimenting immediately, and the explanation was too professional.

"Well, this is basically the case. I'm considering your father has autonomic neurological problems." Zheng Ren continued: "When patients with vasovagal fainting are upright, the blood accumulation in the lower limbs is more serious than that of normal people, the central venous pressure is significantly reduced, the blood volume of the back heart is reduced, and the sympathetic nerve tone continues to increase."

Luan Yingjie understood it half or not.

"Then it causes a significant increase in the ventricular contraction force, overstimulating the pressure receptors in the lower wall of the left ventricle, which reflexically causes a decrease in sympathetic tone, vasodilation, blood pressure, sudden brain ischemia, fainting, sometimes accompanied by increased vagus nerve tone and bradycardia."

"Boss, have you studied that kind of C nerve fiber without myelination?" Su Yun suddenly asked.

"Have you studied it? Use guinea pigs in the laboratory?"

"Well, it's so interesting." Su Yun smiled proudly and said, "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, just like he was listening to the book of heaven.

20 minutes later, the car drove home, and Zheng Ren got off the car and called.

He first called Zhou Litao, asked if he was busy, and then told him about his situation.
