"Usually the color of urine is light yellow, transparent, turbid, reddish, red, milky white six colors!" Every time Tang Yi said a color, his finger raised a finger, "The first two colors are the color of normal human urine, and the last four can reflect different types of urological diseases." ”

Looking at the students in the audience who were sitting seriously taking notes, Tang Yi nodded with satisfaction, "For example, the color of the patient's urine is red, but there are no other symptoms. Can we say that the person who comes to the doctor has a disease? A, no. ”

A student raised his hand in the air, "Teacher, aren't you inconsistent?" ”

"Contradictory?" Tang Yi chuckled and shook his head, "When we diagnose and treat patients, we also have to combine the patient's description, physical examination, etc. to determine whether the patient really has a disease. Everyone has eaten red heart dragon fruit, if a large amount of ingestion, the pigment enters the blood circulation to the kidneys, so that the urine color turns red when urinating. This is a normal physiological phenomenon, no need to use medication, just stop eating red heart dragon fruit. If the patient does not take any medication or has eaten a pigmented food, and still has red urine, it means that hematuria has occurred. At this time, we should be vigilant and think about what causes hematuria in our minds. ”

"The smell of urine is fishy, severe ammonia, rotten apples, fishy, feces, caramel, rat droppings. The fishy smell is a normal taste, and the rest can indirectly reflect what disease the patient may have. Tang Yi looked down at the plastic bottle on the table, "I told you so much just now, and the students below came up one by one to observe Zhang Zhifeng's urine." ”

The students sat in the audience, and none of them moved. Tell me, listen to it, you told us to observe other people's urine, and you told us to smell it, it's disgusting, and it's even a little perverted.

There were a few students who really wanted to study medicine, and they looked around, did not take the lead, and were embarrassed to stand up.

Tang Yi stepped out of the way, "Zhang Zhifeng, this is your urine, you will be the first one!" ”

Zhang Zhifeng's face blushed to the base of his neck, it's my urine, yes, I will be embarrassed if I look and smell it in front of so many people. In case it gets out, I'm still out of school.

But seeing Tang Yi's cold gaze, Zhang Zhifeng swallowed his saliva, plucked up his courage, walked to the lectern, lowered his head and sniffed on the mouth of the bottle, "MD, if you die, you will die, Lao Tzu is studying medicine, and he doesn't even dare to smell his own urine, and he still learns to fart!" ’

"Holy, is it so close?"

"It feels like his nose is touching the mouth of the bottle."

"It's disgusting."

……

Zhang Zhifeng blushed, sighed, raised his head, and kicked the classmates below, "I at least smell my own urine, and it will be you in a while, see what you do?" ”

yes, that's his own urine, what's wrong with smelling it? When you go to the toilet, it is a long time for urine to drip on your hands. What about us? Got other people's urine on your hands and nose......

Thinking of that scene, many people shuddered.

Disgusting.

It's disgusting.

It's really disgusting.

When Zhang Zhifeng was lying on the podium and smelling the smell just now, the corners of Tang Yi's mouth twitched, and now he noticed the expressions of the students and shook his head, "Didn't the high school chemistry teacher teach you what to do when you smell a pungent smell?" ”

Li Yumeng, who was sitting in the front row, lit up in his eyes, "Open the gas collection cylinder slightly, and gently stir it at the mouth of the bottle with your hand, so that only a very small amount of gas enters the nostrils." ”

I only heard a breath of breath in the classroom, and some girls even patted their chests, glad that Old Tang reminded me in time. Otherwise, what should I do if I lie too close and the tip of my nose touches the mouth of the bottle and is stained with urine?

Compared with the happiness of the classmates, Zhang Zhifeng looked at Tang Yi's back with a resentful face, "Why didn't you say it earlier, my nose touched the mouth of the bottle just now, and now I still feel that the tip of my nose is cold, if I wasn't afraid that my classmates would find out, I would have gone to the toilet to clean it a long time ago." ’

With the method, the students no longer rejected, one by one they walked up to the podium, observed the urine in the bottle, gently stirred it with their hands, and smelled it.

Until the last student stepped off the podium, Tang Yi's face leaked a look of disappointment, "Let's talk about what I observed!" ”

"The urine is yellow, a little cloudy, and the smell is a little strong!"

"In addition to what Wang Yu said just now, I also found that there are more bubbles."

Tang Yi's fingers lightly tapped on the podium, "Is there anything else?" ”

The students were stunned by this question. What else? Isn't that what those dots are?

Tang Yi shook his head and pointed to Zhang Zhifeng standing beside him, "After you came to power, you asked Zhang Zhifeng a word, have you looked at him?" What is the fundamental purpose of my observations of urine? Ignoring my words? Observe the color and smell of the urine, combined with the patient to give a rough diagnosis. If you are doctors, you don't know how many patients will be delayed. ”

Standing on the podium and looking at the students below, Tang Yi took a deep breath, walked to Zhang Zhifeng's side, and pointed his finger at the corner of Zhang Zhifeng's eyes, "The secretion of eye feces increases, the eye feces are yellow and dry, the mood is impatient and impulsive, and after he came on stage, he swallowed saliva many times, and his mouth chirped, proving that his mouth is dry." Have you noticed this? ”

Eye droppings? I wiped, Zhang Zhifeng hurriedly stretched out his hand to wipe.

Tang Yi looked ahead and pointed his finger at Zhang Zhifeng, "Don't wipe it, you guys will come to the stage one by one for me to observe Zhang Zhifeng." ”

Many students bit their lipes and walked past Tang Yi with their heads lowered in shame, they didn't blame Tang Yi, but felt that they were too stupid. How can you see a doctor without seeing people? Take care of yourself and look at the urine, MD, and resolutely do not make such low-level mistakes in the future.

Zhang Zhifeng was very aggrieved and held his mouth, "MD, old Tang, you are a king and a calf, if this matter spreads, if I can't find a girlfriend during college, it will be your fault." ’

When the last student walked off the stage, Tang Yi pressed his hands on the podium, "Have you observed it clearly?" ”

"Clear."

"Observations clear."

"See clearly."

A few voices rang out in all corners of the classroom.

For this answer, Tang Yi is very dissatisfied, in addition to medical skills, a doctor also needs to firmly believe in his own diagnosis, and if he doesn't even have this confidence, how to use medicine?

If he hadn't agreed to Zhan Youcheng, Tang Yi really wanted to turn around and leave, "If you don't observe clearly, you will go on stage to observe again until you observe clearly." ”

When the words fell, many students raised their heads to look at Tang Yi, hesitated for a long time, slowly stood up, and walked onto the podium again.

Surrounded by more than a dozen students, pointing to the eye droppings on his face, Zhang Zhifeng felt like an orangutan in a zoo, with no strength, but only for tourists to see.

Until Zhang Zhifeng was left on the podium, Tang Yi walked up to the podium, picked up chalk and wrote on the blackboard, while saying, "There are many eye feces, dry yellow, yellow urine, dry mouth, dark circles, impatient and impulsive, combined with the above points, it can be concluded that it is likely to be a disease caused by a strong liver fire." The liver fire is vigorous, and the cause is mostly caused by emotional failure, qi depression and fire, or heat accumulation in the liver meridian. External fiery evil, smoking, alcohol, excessive consumption of fatty and spicy things, can brew heat and turn fire, and commit liver meridians, so that the liver and gallbladder qi are reversed. ”

Tang Yi's hand holding the chalk was very strong, and the chalk broke several times during the writing process, "When the liver fire is relatively strong, the fire goes up, and the liver fire will cause some pathological manifestations in liver-related organs, and the most obvious manifestations are on the face and eyes. Anger hurts the liver, and liver problems are often manifested on the face. What does liver belong to? Wood. What do the eyes correspond to in the five elements? It is also wooden, so the eyes will have an increase in eye discharge and blurred vision. ”

Turning his head, Tang Yi threw the chalk in his hand on the podium, "Then let me ask you a question, why does the liver fire appear yellow and the fishy smell of urine is heavy?" ”

"The liver is hot, and the fire is the same as the fire, so there will be yellow urine!"

"Liver fire is not the same as fire. Liver fire is mostly caused by kidney yin deficiency or internal heat. Traditional Chinese medicine says that fire is inflammatory, so the upper part of the human body can appear as hot. Tang Yi pointed to his brain, "What is this class we are taking today?" Five elements, aquatic wood. Because the kidney is the main water, the lack of kidney water will lead to kidney yin deficiency in the patient, and if the kidney yin deficiency is deficient, it will lead to deficiency heat and endogenous, and even deficiency and fire. ”

Tang Yi stretched out his hand, "Understood?" ”

Li Yumeng looked at the words on the black and white, and gritted her teeth, "Old, teacher, is all liver fire related to kidney water?" ”

Seeing that it was his beautiful school girl girlfriend who asked the question, Tang Yi forcibly suppressed the anger in his heart and leaked out of Hexu's smile, "Insufficient kidney water will cause liver fire, but not absolutely." As I just said, the exuberance of the liver fire is not unrelated to emotions and life and rest, so we can't blindly attribute the prosperity of the liver to kidney deficiency. People with strong liver fire are prone to sweating, sweating a lot, and the water is not replenished, and the phenomenon of yellow urine will naturally occur. ”

"The liver fire is too long, the fire is too strong and it will hurt the yin, the last class told you, yin deficiency but yin, yang deficiency but yang, fire hope, natural lack of yin, resulting in liver yin deficiency, and finally lead to liver and kidney deficiency. When patients with strong liver fire are treated, it is certain that the liver is thinned, of course, it is not enough to only thin the liver, but also to clear the fire and clear the heat, and also to extinguish the fire. In the case of Zhang Zhifeng, what kind of medicine do you think is appropriate? ”

At this moment, many people took out their mobile phones and searched on the Internet for how to treat liver fire.

Someone was the first to find the answer, "Gentian Liver Pills, Chai Hu Shu Liver Powder, Coptis Supernatant Tablets, and Shugan Powder can all treat liver fire." ”

"There are also, compound antelope antihypertensive tablets, compound Luobuma granules, and gastrodia hook vine granules!"

Seeing the students in the audience speaking enthusiastically with their mobile phones, Tang Yi shook his head, "Do you think you answered correctly?" The classmate just said that as long as the gentian laxative liver pill and gentian laxative liver pill are aimed at headache, dizziness, deafness and tinnitus caused by the vigorous liver fire, this medicine has a bitter taste and is easy to hurt the spleen and stomach if taken for a long time, so those with weak spleen and stomach should not take it for a long time. Do you see Zhang Zhifeng has dizziness, vertigo, deafness and tinnitus? No, is this medicine the right symptom? That's right, because this medicine does treat liver fire. Does it work? Definitely, but does it need to be so troublesome? ”

Tang Yi stretched out his hand and spread it out, "I'm not opposed to searching for treatment options on the Internet, because you haven't been exposed to pharmacy yet." When searching, please take a look at the effect of the drug, as well as the main target population, precautions. Dandelion is cold, has the effect of clearing heat, reducing swelling and dissipating knots, etc., and can be used to relieve symptoms such as less urine and swollen and painful eyes caused by vigorous liver fire, and can play a role in diuretic laxative, liver clearing and brightening purpose. Therefore, Zhang Zhifeng only needs to go to the pharmacy to buy five yuan of dandelion tea, and he can recover in a few days. ”
