The three little fat men listened attentively like good babies, and Yang Tian slowly spoke. Pen "Fun" Pavilion www.biquge.info

"First of all, we must adhere to the principle of seeking truth from facts, respect the facts in everything, and not speculate, just now you just saw the one-sided symptoms of the fourth child, and began to speculate, which is not advisable."

"The diagnosis of the disease is directly related to the subsequent treatment of the patient, and whether the diagnosis is accurate and whether the treatment is symptomatic directly determines the fate of the patient.

"It's not a big deal, but I want to serve as a warning to you, lest we waste our lives in the future when we really become doctors."

Yang Tian's tone was a little heavy, and he thought of his father.

If it weren't for the misdiagnosis, the father would now ......

Forget it, Yang Tian shook his head and looked at the three people in front of him, they all lowered their heads.

Huang Huawen, who taught biochemistry, told them a few days ago, and this time he was criticized by Yang Tian again, and it was really embarrassing to jump twice in the same pit.

"Secondly, we should adhere to the principle of common first and then rare, and in the case of the possibility of several diagnoses at the same time, common diseases and frequent diseases should be considered first, and rare diseases should be considered last."

Yang Tian glanced at the three of them.

"Everyone has learned mathematics, so I don't need to talk more about this probability problem, right? The fourth child is also an example, let me give you a more popular one, you have a fever and sneezing, what is the first thing to consider? ”

"It's influenza."

The fourth replied weakly.

Yang Tian slapped his thigh, "That's right!" It's influenza, but also common diseases such as upper respiratory tract infections or tonsil inflammation, and no one subconsciously thinks of HIV, right? ”

The three of them nodded again and again, although the initial symptoms of HIV infection also include the symptoms of cold and fever, but if this is not a bad thing, who will think in that direction?

Hey, it seems to be far away, cough cough, it's all Yang Tian's fault!

The little fat man and the boss were full of eccentricity, but the fourth child listened carefully, as a good student who loves to learn, he would not let go of any opportunity to learn, not to mention that what Yang Tian is saying now is exactly within the scope of his preview goal.

The fourth child won't know now, just because of Yang Tian's words, he directly made the right choice in the rematch of the hundred miles of doctors in the near future, and successfully entered the sight of his future mentor.

All hard work will pay off, and this is not just a rhetoric.

Yang Tian continued to carry out his educational work in an orderly manner.

"Then there is monism, a patient comes to you, there will be many manifestations, such as the fourth, he has bleeding gums, bruises on his body, slow wound healing, and his face is not good-looking, plus he just had a cold some time ago, this is five manifestations, if you look for them separately, there will be more diseases that can correspond."

"But we give priority to the possibility that all the symptoms are caused by the same disease, and we have to think about it this way."

Yang Tian paused, and the three little fat men waited with wide eyes.

The front is all diagnostic theories, and the following is about to be dry, to be honest, they also want to know how Yang Tian made the diagnosis.

"Vitamin C, also known as L-ascorbic acid, is a strong antioxidant that can directly participate in redox reactions in the body, which is conducive to the absorption of iron in food and can enhance the body's immunity."

"Vitamin C is a necessary substance for collagen formation, which is what those girls want to get every day with a face dress, in fact, it is good to eat more vitamin C."

"Severe vitamin C deficiency can cause scurvy, the main manifestation is the increase in capillary fragility and easy rupture, the fourth is that if you touch it casually, the capillaries inside will break, and then lead to congestion."

The three of them nodded in realization.

"Then there is gum rot, loose teeth, fractures and wounds that are not easy to heal, and the fourth child is manifested by bleeding gums and wounds that do not heal, combined with the fact that he has only recently recovered, and his resistance has also become a problem, so after a comprehensive judgment, it is vitamin C deficiency."

"I see!"

The three of them nodded one after another, it was really up!

"Speaking of vitamin C deficiency and scurvy, I have a little story here, have you all heard of the voyages of Columbus and Magellan?"

The three of them nodded, this is something that has been talked about in history textbooks.

"Their journey was far from going as smoothly as they had imagined, and many of the crew members suffered from a disease called scurvy, in which the gums swelled, bled, their teeth became loose, and finally they died in agony."

"Actually, they're just vitamin C deficient."

Yang Tian glanced at the three of them and began to popularize knowledge.

"Humans and other primates can't synthesize vitamin C, so they must be consumed through food."

"Fresh vegetables and fruits, as well as bean sprouts, are rich in vitamin C, but the ascorbate oxidase in plants can nourish the flowers and render them useless, so the amount of vitamin C in fruits and vegetables that have been stored for too long will be greatly reduced."

"In ancient times, the conditions were difficult, and it was impossible to eat fresh food on the ship, so naturally there was no source of vitamin C."

"Later, after figuring out the situation, the ships began to be equipped with rum in large quantities, because these fruit wines can replenish some vitamin C and are easier to preserve than fresh vegetables."

"So, the sailors in film and television works are all drunkards, and there is a reason for that, in that case, if you don't become an alcoholic, you will become a dead ghost."

"I see." The boss nodded, the teacher really hadn't talked about this thing in class.

"So, just eat more vegetables and fruits?" The little fat man came up, and he was more concerned about the result than the principle and process.

"It's right to eat more vegetables and fruits," Yang Tian nodded, "Vitamin C is unstable to alkali and heat, and if vegetables are cooked for too long, the vitamin C in them will also be lost a lot, like those vegetables in the canteen that are boiled until they turn black, which are basically useless." ”

Yang Tian turned his face to look at the little fat man, "Don't you have oral vitamin C, just take two tablets if you have nothing to do, and those medicines in your cabinet, read more instructions by yourself when you are free another day, don't be blind to the money to buy medicine, how many people are poor and have no money to buy medicine!" ”

"Uh-oh." The little fat man shrank his head and hid aside, pretending to bow his head and study the vitamin C he snatched from the fourth child.

"You know a lot." The fourth child finally broke free from one kind of excitement, and then plunged into another kind of excitement, and there were almost small stars flashing in his eyes when he looked at Yang Tian.

The worship of good students who are dedicated to learning comes from their bones, and for them, it is a painful and happy feeling to be crushed by Xueba from the knowledge level!

"Yes, Yang Tian, how do you know these things, not only professional, but also extensive, I think what you talk about is better than what those teachers talk about in class!"

The boss is not stingy with his praise, if you want to say that he is the most convinced in this profession, it must be that Brother Tian didn't run!

"That's it!" The little fat man came over again, "I see that you are busy sleeping every day, when did you learn?" ”

"Hey, do you want to know the answer?"

Yang Tian smiled, looked at the three of them nodded again and again, wiped his hand in his hair, and raised his head, "Because brother, I am a genius!" ”

"Go, go, go! I think you're a narcissist! ”

The little fat man pursed his lips and slammed back mercilessly.

“……”

The boss silently wiped his sweat.

The fourth man pushed his glasses, and just now for a moment, Yang Tian's tall and majestic image in his heart collapsed.

"Oh yes." Yang Tian suddenly thought of something, turned around and began to rummage through the little fat man's cabinet again, "The fourth child needs to take medicine, and the two of you had better take a little too." ”

"No, these two bottles."

Yang Tian handed the two medicine bottles that had just been turned out to the boss and the little fat man respectively.
