The next day, that is, the sixth day after Du Wenhao returned to the capital, there was a light rain in the sky.

The first night, Du Wenhao had already told his master Shen Shengping about the events of these days. Master Shen decided to go early this morning to inquire about the situation.

After Master Shen left, Du Wenhao was at a loss and didn't know what to do.

Du Wenhao also had no intention of going to the front hall to diagnose the patient, and if he had money and waited for others, he didn't need to take action in person for ordinary diseases. So he took a medical book and sat in the study to read it. The little tiger cub Xiaoke was obediently lying at his feet, listening to the sound of rain outside the window, squinting and napping.

All the women knew that Du Wenhao needed to think carefully at this time, and they didn't dare to come to disturb, so they only let Du Wenhao study alone in the study.

But he looked at the book, but his heart was not in the book, he always thought about the Empress Dowager and the emperor, remembered their kindness to him, especially the Empress Dowager, and wanted to go to mourn, but before Master Shen left, the two had already said that they would make a decision after the situation was discovered, and everything would wait and see what would happen. This is a matter of life and death, and at such a time, we must not go out with a big head. Anyway, there is still some time for the mourning period, and I will go to mourn after the situation is confirmed.

He was in a state of great depression, when he heard a knock at the door, and he replied listlessly: "Who, come in, the door is not bolted." ”

The door creaked open, and a head stuck in: "Brother, I'll ask you for some medical skills, okay?" ”

Du Wenhao looked up, but it was Xue Fei'er, and he smiled reluctantly: "Fei'er, what's the matter, this time I'm working hard?" Didn't you say that studying medicine was to accompany your sister Qin'er, the prince, to study, and watch and play indiscriminately? ”

didn't wait for Xue Fei'er to speak, another person appeared behind her, but it was Ke Yao, holding a book in his hand, and said with a smile: "Brother, she is arguing with me and is not convinced, so she came to you to argue who is right and who is wrong." ”

"Oh, I love to learn so much, it's a good thing, learn and think, learning is to be diligent in thinking, come in. Take a stool and sit on it. ”

The second daughter took a stool and sat next to Du Wenhao. Ke Yao said: "I was reading a medical book just now, and there was a sentence that I couldn't understand, so I wanted to come and ask Doctor Qian, but he was diagnosing in the front hall with his wonderful hands and handsome hands, and he was so busy that he was embarrassed to disturb, so he went to ask Sister Fei'er, but her statement was different from my understanding, and the two of us quarreled." She's stubborn, and she's going to bet ...... me."

"Hey! You're going to bet with me, okay! Xue Fei'er glared.

Du Wenhao smiled: "It doesn't matter who bets with whom, what are you betting on?" What's in it for me as a referee? ”

Ke Yao snorted: "Greedy brother, come and ask us for benefits!" - We bet on who loses and who learns to bark a puppy. ”

Du Wenhao laughed: "This bet is interesting, then I don't want any benefits, it's interesting to listen to the sound puppy you lose, I think Ke Yao should learn more like ......!" ”

"I hate it!" Ke Yao gently slapped Du Wenhao with the scroll in his hand, "How do you know that I will lose?" Hum! ”

"Let's talk about it first, what's the argument about?"

"Sun sickness!" Ke Yao handed the book in his hand to Du Wenhao: "Oh, that's it." ”

Du Wenhao took it and took a look, it was a sentence from Zhang Zhongjing's "Treatise on Typhoid Fever": "The sun is sick, the pulse is floating, and the head is strong and cold." Then he asked, "What's wrong with that?" ”

Ke Yao said: "We are arguing whether there should be fever in the basic symptoms of sun sickness. I said that Zhongjingshu clearly wrote that there are only three basic symptoms of sun disease: pulse floating, strong head pain and chills, and there is no fever, so fever is not a basic symptom, that is to say, sun disease does not necessarily have fever, and what does not have fever may not be sun disease. ”

Du Wenhao looked at Xue Fei'er: "What do you think?" ”

Xue Fei'er said: "The disease is in the sun, guarding the qi and resisting evil, there must be a fever, self-evident things, there is no need to write!" ”

Ke Yao said: "Are you saying that the medical saint wrote this paragraph and omitted the basic symptoms of this fever?" ”

Xue Fei'er said: "I didn't say that he missed writing, what I said was that there was no need to write, fever is a natural phenomenon, and whether you write it or not is included in it." It's like people feel uncomfortable when they are sick, but do you have to write uncomfortable for every illness? ”

"You're using strong words!"

"You're a vexatious quibble!"

Du Wenhao laughed: "Okay, don't fight, let me ask you first, how did the sun disease happen?" Ke Yao, you said. ”

"It's not going to bother me!" Ke Yao said triumphantly, "The Sun Sutra is on the surface of the human body, just like the courtyard wall of the family, the external evil invades, the Sun Sutra will bear the brunt, the righteous qi in the body will rise up to carry the evil, and the good and evil will clash on the surface of the body, resulting in sun disease." ”

"That's right, why does sun sickness have symptoms of swollen pulses, strong headaches in the head and chills? Fei'er, you say. ”

"What's so hard about that?" Xue Fei'er also said a little proudly, "The pulse is the first of qi, the external evil is coming, the righteous qi is floating on the surface, resisting the evil outward, and the pulse should float." So the pulse floats; The sun meridian begins here in the eye socket, passes through the forehead, passes through the neck, and goes down to the feet. The invasion of external evils, the sun meridian is blocked, and if it is not passed, it will be painful, so it will have a headache at the beginning, and the neck will be stiff; As for the cold, it is even simpler, Wei Qi has the effect of warming the skin and nourishing the body, and the invasion of external evils, Wei Qi is busy resisting external evils, how can there be time to warm the skin, not to mention, under the effect of wind and cold, Wei Qi is contained, and naturally it will not play the role of warming the skin, so people will have sun disease, they will be cold and afraid of cold. ”

Du Wenhao nodded approvingly: "Fei'er has made a lot of progress during this time, and she is not as ignorant as before." ”

Ke Yao said with a smile: "Sister Fei'er watched me study medicine and didn't want to be left behind me, so she also watched." ”

Xue Fei'er snorted: "Who compares to you?" Ever since my brother came to our Dongda County, I have been studying medicine with him. I've always been serious about studying medicine! Right? Elder brother! ”

Du Wenhao smiled: "Yes, yes, Fei'er is very hardworking, let's not talk about it, and then talk about sun disease." Both of you have learned the basics of sun sickness and the three basic signs of sun sickness. The basic symptoms are the most basic characteristics of a disease, as long as it is this disease, it must have this basic characteristics, without these characteristics, or the absence of one of them, it can generally be concluded that it is not this disease. This is the basic symptom. The study of medicine must be like this, and each disease must be learned from the basic symptoms of it, and only by firmly grasping the basic symptoms can we respond to all changes with the same. For example, this sun disease, pulse floating, head pain, cold, all three are indispensable, if it is just headache, chills, but the pulse is not floating, it is not a sun disease. Of course, there may be different symptoms in special circumstances such as coercion or a new illness triggering a previous illness. That's a different story. ”

Ke Yao said: "That's it, it is clearly written in the book that sun disease is the three basic symptoms, but there is no fever, so it can be said that sun disease can not be feverish, and fever cannot be said to be sun disease." ”

Du Wenhao said: "Ke Yao is right in the second half of this, at the beginning of the sun disease, Wei Yang was depressed, and when it has not yet stretched, there can be no symptoms of fever, but then due to Wei Yang's stretching, fever will inevitably appear. ”

Xue Fei'er stroked her palms: "How is it!" I'm right! ”

Ke Yao was very unconvinced and said: "Brother, you are eccentric and mess with the medical book!" Just to her! I don't follow! ”

Du Wenhao said with a smile: "You can joke about other things, in terms of medical skills, I never joke, because the speaker has no intention of listening, and others don't hear the joke. ”

"Then you say, since fever is also a basic symptom of sun sickness, why is it not written in the book?"

"It's written in the back, look at the ephedra soup certificate at the back! I'll hear it! ”

Ke Yao said hello, turned to the back of the ephedra soup, and shook his head: "Sun disease, headache and fever, body pain, low back pain, joint pain, bad wind without sweating and wheezing, the ...... of ephedra soup"

"Well, didn't you say that there is a fever from the sun!"

"Where?" Just now, Ke Yao only looked at the book of heaven in a frustrated manner, but he didn't pay attention to the words in the book, and after listening to Du Wenhao's words, he came back to his senses and looked down carefully, sighed, and said, "Sun disease, headache and fever...... really have a fever?" ”

Du Wenhao said: "The reason why fever is not listed as an outline in the previous article is mainly because sun disease is divided into typhoid fever and stroke. Therefore, fever is also a basic symptom of sun sickness. If you look back, there is also a sentence that you are arguing about, and it is clearly written,—— 'Sun sickness, fever, sweating, bad wind, slow pulse, is called stroke.' ”

Ke Yao took a closer look, and sure enough, he secretly complained in his heart, regretting that he hadn't read the book carefully just now, his eyes rolled, and he asked with a grin: "Brother, I know the stroke in what you said in this sentence, that is, the mouth and eyes are crooked, and the limbs are not successful, right?" As he spoke, he rolled his eyes and crooked his mouth, his hands dangling in the air and waving.

Du Wenhao shook his head with a smile and said: "The stroke you said is hemiplegia, which is different from the stroke of the sun certificate, and the stroke here is the meaning of feeling the wind evil and curing the disease." ”

"I see." Ke Yao looked suddenly enlightened, thought about it, and asked, "What is the evil wind?" Is there a difference between a bad wind and a bad cold? ”

"Of course, there is a difference, both of them are a feeling of wind evil entering the body, well, it can be understood in this way, a person is sick, if there is no wind, he does not feel cold, but when the wind blows, he feels cold, this is called evil wind; If you sit at home and there is no wind at all, and you still feel cold, you have a bad cold. ”

"That's it," Ke Yao's eyes rolled a few times, and he salivated and said: "Is it understandable that a person is sick, even if he feels cold in a house where there is no wind on a hot day, it is a bad cold, on a hot day, there is a little wind, people think it is very cool, but he feels cold all over his body, this is a bad wind, I understand it right?" ”

"Exactly!"

"Hehe, brother, I'm still quite smart, right?"

"I've always thought you're smart."

Xue Fei'er said: "Yes, you are very smart, don't forget our ......"

Ke Yao ignored her, and hurriedly asked Du Wenhao again: "Brother, you just said that there are strokes and typhoid fevers in sun disease, are these two different?" ”

"Of course not."

Ke Yao's eyes widened, looking hungry and eager to learn and ask questions: "Then how to distinguish it?" ”

Xue Fei'er coughed twice and sneered, "Oops! Why do you want to fool Lai Meng? Don't forget the bet!

Ke Yao laughed dryly: "Who forgot? I don't have anything I don't understand, ask my brother! ”

"Come less! Why, I want to reveal this matter while talking? No way! Hurry. ”

"What are you going to do?" Ke Yao asked knowingly.

"Learn to bark a puppy! Willing to lose!

Ke Yaoqiao's face was a little flushed, and she salivated and said to Xue Fei'er: "Hehe, a good sister is the most distressed, how can you bear to let your sister learn to bark a puppy, right?" Why don't I ask you to come down to the restaurant? Pick anywhere in the capital, you say that one is that, you can eat any delicacies from the mountains and seas, how about it? ”

"Ha, you really know how to make wishful thinking, who doesn't know that it is the mourning period of the emperor and the empress dowager, and all the restaurants in the capital have been ordered to close their doors to mourn, and they can only open after the mourning period. What are you taking me to eat? A small noodle shop on the side of the road? ”

Ke Yao smiled dryly: "I'...... I forgot about it. If you don't wait until after the mourning period, I'll invite you. ”

"Excuse me, this mourning period is not sure when it will end, besides, waiting for that meal is not as interesting as listening to two puppies barking. Come, my ears may stand and wait. ”

"Good Sister ......"

"Willing to lose! Not negotiable! ”

Ke Yao still salivated and said, "It's really not good, then let's go, I'll learn it to you when I go back!" ”

Ke Yao stood up and was about to leave. Xue Fei'er grabbed her: "Just learn here!" Brother also said it just now, and he also praised you for learning how good a puppy can be called! Hee-hee-hee"

Speaking of the back, Xue Fei'er couldn't help but laugh.

Du Wenhao also said to Ke Yao: "Exactly, I've heard you cry, but I haven't heard you learn to bark." Call it! ”

"Ruthless brother! will bully me! Hum! Ke Yao glanced at Du Wenhao, bit his red lip with silver teeth, looked out of the door, and saw that there was no one near the left, so he turned his heart sideways and pouted: "Just call it, what's the ,—— Wangwang, Wangwang!" ”

Giggle......

Hahaha......,

Xue Fei'er squatted on the ground with her stomach in her arms, and even tears came out, and Du Wenhao also leaned forward and closed with laughter.

The little tiger cub who was napping on the ground was also awakened by them, raised his head, shook his little furry head, looked at this and that, and didn't know what they were happy about.

Ke Yao glared and said, "Smile!" It's better to laugh at you two ruthless thieves! ”

Xue Fei'er giggled and pointed at Ke Yao, "Do you think you are kind?" That's my bet to win, if I lose, maybe you're going to fix me! Hahaha......"

Ke Yao's small chest straightened: "If you have the ability, bet again!" I'm going to win you this time! ”

"Bet on it, say, bet on what?"

"Let's talk about the question asked by Brother Gamble! Whoever answers wrong loses! ”

"Okay! What to bet on? Or do you lose and learn to bark? ”

"Nope! I've learned everything, and you've learned it even if you lose, at most, I'll have to get it back with profits this time! - Let's this time, whoever loses will not only have to learn how to bark, but also have to crawl around on the ground! Do you dare? ”

Xue Fei'er is also a master who is not excited, where she is willing to admit defeat, her high chest is also straight, and she said: "I'm afraid of you, come on!" - Brother, you ask! ”

Du Wenhao smiled and said: "Bet on this, if you lose, you will hurt your face, and it will not be good to hurt your harmony when the time comes......"

"It's okay! Brother, we're just gambling, and she's just learning how to crawl around in front of the two of us, there's nothing to be ashamed of, right, Sister Fei'er? ”

Xue Fei'er nodded and said, "That's right, it's not a shame for you to wait a while and crawl around on the ground to learn how to bark a puppy." Hee-hee-hee. ”

"Humph! Let's see who loses! - Brother, you just have to ask the question! ”

Du Wenhao shook his head: "Okay, let's use the sun certificate to continue the topic just now, didn't Ke Yao ask a question just now, what is the key to the difference between the two classifications of typhoid fever and stroke in the sun certificate?" ”

Ke Yao immediately raised his hand and said, "I'll say it first!" Typhoid fever of this sun disease ......"

Du Wenhao smiled and said, "Let's talk about the loss first." ”

Ke Yao immediately understood: "Yes, yes, it's better to write them down separately and judge them for my brother, so it's fair!" ”

Xue Fei'er said: "Okay! ”

The two sat at the table separately, holding the pen and thinking, biting the pen and thinking for a while, they both secretly glanced at Du Wenhao and asked him to wake up, but Du Wenhao smiled and groaned without saying a word and lowered his head to read the medical book. The two of them cursed in their stomachs, and had to write their own answers and hand them to Du Wenhao.

Du Wenhao looked at it, shook his head, and said: "The typhoid fever and stroke of sun disease all belong to sun disease, so both of them have their own symptoms in addition to the basic symptoms of sun disease. Most of the differences you write are these circumstantial evidence, not the key. Let's analyze first, as far as stroke is concerned, it is the disharmony between the camp and the guard, that is, the guard is not solid outside, and the camp is not guarded inside, so the camp yin leaks out, and people will sweat. It is precisely because of the loss of camp yin and the leakage of sweat that the pulse of the evidence of sun disease and stroke will be slowed down. In short, sun disease stroke, sweating, and slow pulse are the main dialectical points. ”

As soon as he said this, Xue Fei'er and Ke Yao's faces changed slightly, and their faces were still as if nothing had happened. But they didn't dare to look at each other.

Du Wenhao continued: "Looking at the sun typhoid fever syndrome on the other hand, its pathogenesis is different, it is Weiyang depression, and the camp is gloomy and stagnant, so the sweat in the body cannot be excreted through the pores on the body surface, and people with this disease do not sweat in their bodies. Due to the ferocity of the cold evil of the solar typhoid syndrome, Weiyang was forced to close and contain, and the camp was gloomy and stagnant, so the pulse was tight. Of course, there are some other symptoms of solar typhoid fever, such as body pain, nausea and vomiting, etc., but they are not the main signs. ”

Speaking of this, Du Wenhao glanced at the second daughter and said with a smile: "I have analyzed the etiology, pathogenesis and main symptoms of the two, who can summarize what I said just now, what is the key difference between the solar typhoid syndrome and the solar stroke syndrome?" ”

Xue Fei'er muttered: "You have explained everything, if you still can't hear it, this medicine will be in vain, naturally sweating and pulse." Solar stroke syndrome sweats and the pulse floats slowly, while solar typhoid syndrome does not sweat and the pulse floats tightly. - I didn't think about it this time, don't count it."

Ke Yaoxi said: "Okay, good! I was also in a hurry just now, so I missed it. It's not exactly ......! ”

Speaking of this, Ke Yao seemed to realize something, looked at Xue Fei'er and grinned, "You also missed something?" ”

Du Wenhao shook the paper in his hand: "In addition to the general signs of sun disease, the two of you have talked about it, the key difference is that Fei'er only wrote about the pulse, and Ke Yao only wrote about whether he was sweating." So neither of them answered all, they only answered half of them correctly, and this time it was a tie. ”
