Chen Yu revealed a look of disappointment. "If you also have this diagnosis, then there's no need to mention it. They've already said it."

Cang Xuande waved his hand, stood up and walked forward, "Lee Yifann, you can leave!"

Just as he had thought, Lee Yifann took Kuang Ziming's answer. He was really too optimistic, overestimating Lee Yifann.

Hearing this, Lee Yifann could not help but laugh, he did not have any intention of retreating, he chuckled and said: "Master, Grandma Chen, please listen to me finish. Grandma Chen, you are indeed a staphylococcal infection, but it's not an ordinary staphylococcus. It's a staphylococcus aureus infection! "

"Hmm?" Cang Xuande suddenly stopped in his tracks, turned his head and looked at him with surprise, with some disbelief: "How did you make this kind of diagnosis?"

"It's very simple!" Lee Yifann walked in front of Old Madame Chen, brushed off her hair, and pointed at the purplish-red spots, "These spots are called infiltrating purplish red patches, and are one of the symptoms of infection caused by Staphylococcus aureus. Grandma Chen, may I ask if you feel very hot or dry? "

Old Madame Chen was startled, from the moment she entered the infirmary, she had already felt that it was hotter than usual. Logically speaking, with the infirmary fan on, it should have been extremely cool and refreshing, he thought that it should be the summer when the weather was hot, but hearing what Lee Yifann said didn't seem like it was on his mind?

She quickly nodded and asked with great curiosity, "It seems like it's a little hot. Is there something wrong?"

"Of course! Your disease is called carbuncle, the symptoms are fever, chills, headache, loss of appetite, neck, back, shoulder easy to appear large infiltrative purplish erythema. "However, your symptoms are lighter, and the degree of infection with Staphylococcus aureus is lower," Lee Yifann smiled as he gave his diagnosis.

"What?" Old Madame Chen turned his head to look at his shoulder in shock.

Chen Yu quickly went forward and undid the collar of his mother's shirt. He pulled down her collar and saw that her shoulder was red and purple, as if something had ruthlessly crushed it and caused it to become bloodshot. It was very eye-catching.

"This …"

When they saw the purplish-red spots, Bao Zhiming and the others' pupils constricted. They could not believe their own eyes at all.

How is this possible?

There were actually so many red spots on Old Madame Chen's body?

They didn't realize it at all just now!

Cang Xuande laughed openly and was extremely happy, "Good, good, good! Not bad, not bad, you actually managed to diagnose it, that's right! Big Sis Chen, your disease is carbuncle. It should be because the big fish you bought yesterday is not very clean, and you just happen to be infected by Staphylococcus aureus. It just so happened that the dish might not have been cooked properly, and it had been added to his stomach for a whole night to change the quality. As for the pain in your stomach, it's actually because you've simply eaten rotten food, and your stomach can't digest it. "

After personally hearing Cang Xuande's confirmation, the faces of Bao Zhiming and the others instantly darkened.

Damn it, Lee Yifann had actually guessed correctly!

Hearing that, the Old Madame Chen suddenly realized, "So that's how it is!"

Chen Yu also understood and looked at Cang Xuande gratefully, then turned to her mother and said: "Mom! Look, I already told you not to eat your leftovers. This time, if it wasn't for Doctor Cang spotting it, your body would be ruined. "

"Got it!" I won't eat any more of those leftovers next time! " Old Madame Chen didn't know that the reason he suffered from his illness was because he was unwilling to pour the leftover food on the table.

Cang Xuande sighed, and laughed: "Big sister Chen, I am not talking about you, you are already old, if there are any leftovers, they would fall, and eating those leftovers would not benefit your body. This time, you are infected with a germs, and the next time, you will eat leftover food.

"I was just looking at those dishes and feeling pity! "I'll listen to you. I definitely won't eat next time!" Even if Old Madame Chen ate the leftovers, she wouldn't dare to do it again. She didn't want to suffer from staphylococcus infections again.

"That's more like it! I will write a prescription for you, catch some medicine, and go back and eat some medicine to cure your body of anthrax! "

Cang Xuande laughed and then walked in front of the medicine cabinet, picked up a pen and paper to write down the prescription, then called out to the few disciples: "Follow the prescription to grab the ingredients, do not make a mistake!"

Bao Zhiming walked forward, took the prescription, and quickly followed the instructions.

Cang Xuande took the medicine and prescriptions that he grabbed and handed them over to Chen Yu, "Take the medicine and prescription well, if you don't find it good, then come and take it later."

"Alright!" Chen Yu quickly nodded his head, paid the bill, and left the hospital with his mother.

Once he left, Cang Xuande sat down on the chair, and said to Lee Yifann happily: "Lee Yifann, have you read the relevant books before?"

He felt that the reason Lee Yifann was able to diagnose the illness of the Old Madame Chen was because he had seen relevant books.

Gangrene was a disease that was easy to diagnose and difficult to treat.

Although it was an emergency, its symptoms were mild and difficult to judge. After all, the patient couldn't be allowed to take off his clothes at will.

And when the purple erythema appears in the throat, hand and shoulder, it means already very serious, not timely rescue can endanger life.

"No," Lee Yifann shook his head.

"If not, how did you figure it out?" Cang Xuande was curious, although carbuncle disease was not considered rare, and could even be considered a common postoperative infection in western medicine, Lee Yifann was a student who had not even passed the intern period. He couldn't possibly be born with knowledge of carbuncle disease, right?

Lee Yifann didn't know how to explain it, but he braced himself and replied, "In the school lessons before, I mentioned these common illnesses."

"Oh? I noticed just now that you haven't even had a pulse, and you can tell it's carbuncle just by looking at it? " Lee Yifann said that he had lectured on carbuncle in school before. If he could clearly remember it, it would be proof that his memory was extremely outstanding!

"Actually, I was able to accurately guess that it was carbuncle, and it was all thanks to their advice," Lee Yifann said as he glanced at Kuang Ziming and the other two, "Kuang Ziming diagnosed that it was staphylococcal infection, and Yan Zhou had asked Grandma Chen about the fish, braised chicken, and I knew that it was extremely likely that it was staphylococcus aureus infection. I found the purplish-red spot near Grandma Chen's ear, which proves that my guess is correct. "

He had never been a person who would just take others' words as gossip and laugh them off.

Sometimes, when a patient randomly answers a small question, it might be an important clue to the disease!

Cang Xuande suddenly understood that his heart was quite satisfied with Lee Yifann. Being able to pay attention to these small details proved that Lee Yifann's observation skills were sharp and was good at summarizing. This kind of thinking was extremely important in medicine.

He thought for a moment, then wanted to test Lee Yifann's standards again. Hence, he calmly asked: "If I had asked you to prescribe a prescription for Big Sis Chen, what kind of prescription would you have?"
