Zheng Ren has been observing the old man's performance. His expression is a little indifferent and his hearing drops. But when watching Su Yun speak, he directly raised his voice. It is estimated that he had the problem of ear back when he had lung cancer resection.

During the few minutes of meeting, the old man kept scratching his body with his hands unconsciously, very hard, and even Zheng Ren could vaguely see the blood on his fingernails.

Parasitic paranoia is a rare mental disorder. Patients stubbornly believe that they are infected with parasites. This disease is a kind of mental and psychological disease. Patients often go to dermatology.

This time it happened that the patient was an old patient of Su Yun, so he came to the door directly.

Parasitic paranoia can usually be diagnosed only by medical history. For example, Zheng Ren can directly make a diagnosis by relying on the medical history described by his family.

However, a detailed dermatological examination must be carried out to rule out real parasitic infection or other skin diseases.

To judge whether the patient is suffering from parasitic paranoia, it is important to determine that the patient has no other mental disorders except mistakenly believing that he is infected by parasites, and the paranoia is not secondary to other physical and mental diseases.

The treatment of this disease is difficult and simple. The biggest difficulty in treating parasitic paranoia is to persuade patients to take medicine, which is the first step to successful treatment.

Because patients themselves have a feeling of persecution paranoia, it can be said that it is very difficult to persuade them to take medicine.

"Old Han, you're lucky." Su Yun said with a smile, "we haven't seen each other for a few days. Do you know why I went?"

Su Yun sat directly beside the old man and chatted with a smile. Zheng Ren knew that he was going to start using psychological placebo for patients. It's not surprising that he used the old routine.

This kind of work requires the patient's extreme trust, just like giving the patient such treatment in Haicheng, the effect is limited. But after changing director Pan, he gave a calm face training, and then pushed a tube of glucose.

With the momentum of old director Pan, he has the strength of old doctor and rejuvenation. Let alone patients, even Zheng Rengang rarely questioned his diagnosis when he went.

This is called Qi field, which is an ability accumulated over many years of experience.

He and Su Yun are in this respect... No, Su Yun's goods and female patients are not good when they say things. It just seems that you can't say it casually. Chang Yue cares about this kind of thing very much.

Also, who let Su Yun pass among the flowers? At first glance, he is a good hand at attracting bees and butterflies.

Zheng rennaohai was thinking wildly. Seeing that the old man's eyes were a little turbid, he looked at Su Yun with dim eyes, grabbed his hand and said distressedly, "Xiao Su, I'm afraid I won't win this time. I'm not looking for you to see a doctor this time. I'm meeting you. We're really seeing each other less."

"Why, don't be ridiculous. You are stronger than me. We have been together for a long time." Su Yun said with a smile.

"I can feel insects crawling around my body. I thought about it and found information on the Internet. My body should be full of insects... Xiao Su, how do you think I can live?" The old man said with a sad face.

He is very serious and depressed. Believe it or not, at least he fully believes that his body is full of insects.

"Old Han, we haven't seen each other for several years. Otherwise, it's fate." Su Yun did not continue to explain the fact that there were no insects in the patient's body, but gently patted the back of his hand with the old man's hand to show comfort, and said in warm words: "I have done a great thing in the past two years."

"I said you were a big man!" The old man had a little spirit this time, and a smile appeared at the corners of his mouth. "Tell me what you did."

"I won the Nobel Prize a while ago... And my boss won the prize." Su Yun is a little strange. Why doesn't the old man know such a big thing?

However, if you don't eat or drink properly, it goes without saying which is more important than having insects in your body.

"Ah!" The old man subconsciously held Su Yun's hand, "Xiao Su, powerful, powerful!"

There was some surprise in the old and turbid voice. We can see that the old man is really happy for Su Yun.

"Our research topic is to treat bugs in the body and special drugs." Su Yun said with a smile, "how else can we say that we are destined."

Zheng Ren looks at Su Yun with a smile. He uses the Nobel Prize as an authority to make psychological hints. For ordinary people, this is undoubtedly very easy to use.

"Good, good." The luster in the old man's eyes soon faded, and the rest were still muddy and anxious eyes.

"Just as Corey has medicine, I'll push one for you." Su Yun said with a smile, "then go home and take medicine for two weeks."

"Xiao Su, you shouldn't be lying to me." The old man was not moved at all. He sighed and said, "you are the smartest child I have ever seen in my life. I am not old enough to be confused. Do you want to give me some medicine as a placebo?"

“……”

The old man is so clear! Zheng Ren sighed with emotion.

Many patients will know countless disease-related situations and information after getting sick. Some are useful and more are useless. But the sentence that a long illness makes a good doctor is right. I'm afraid the old man has long known the relevant information.

But lung cancer has been cured. Unexpectedly, he used that set of things on parasitic paranoia.

Zheng Ren sighed. It's troublesome this time. This is a trick. It's no fun to be exposed.

The difficulty of persuading patients to take medicine has now been directly raised from level a to level s.

Su Yun had moved out the big killer of the Nobel Prize winner at the beginning, but he didn't expect the old man to admit it at all.

"You see what you said..."

"Xiao Su, you are engaged in clinical research, not pharmacological research." The old man has his own logic of thinking, "I'm happy for you to win glory for the country with the Nobel Prize. But if you can win the Nobel Prize, it won't be parasitic disease. You haven't seen me. I don't dare to eat my chicken now, even eggs, for fear of getting worse."

Su Yun, cunning as a fox, didn't know what to say for a moment.

"I guess I can't do this old bone. This time the child said to see you. I thought about coming to see you." The old man said, and two lines of muddy tears came out of his eyes. "We are destined. You worked hard when I was in the ICU a few years ago. You basically gave me the extra years I have lived."

The atmosphere in the office is a little depressed.

"Before I leave, I heard you came back from your hometown. I just came to see you for the last time." The old man repeated it again.
