  Chapter 69 reexamination

  Li Ang browsed through the materials in the memory hall in his mind, and continued: "Have you ever seen a person who has not been able to eat salt for a long time?"

   "Of course I have."

  Yan Yundang vaguely guessed what Li Ang was going to say, nodded and said: "If you don't eat salt for a long time, you will have weakness in limbs, pale complexion, nausea and vomiting.

  No matter how strong a man is, if he does not eat salt for a year or so, he will become extremely weak, unable to mount a horse or lift a knife. "

   "That's exactly the reason."

  Li Ang said: "People must obtain different types of nutrients from food and water every day in order to maintain internal balance.

  Once you eat less or cannot eat, you will become weak and even sick. "

   "Balance Yin-Yang and Five Elements, Qi, Blood and Body Fluid?"

  Yan Lin nodded. As an innate martial artist and General You Jinwu, he grew up in the army.

  What Li Ang said has some similarities with the method of body training taught by the military, but it is not difficult to understand - in the early stage of body training, prescriptions and medicinal baths should be used again.

"Can"

  Yan Lin frowned and said: "The dishes and meals my father eats are all normal, balanced meat and vegetables,

   During this period of time, under the advice of the doctor, I stopped drinking alcohol. "

   "The dishes are normal, but the Duke's problem lies in the stomach."

   Li Ang said helplessly.

   Yan Yundang's megaloblastic anemia, there are two possibilities, one is the lack of folic acid - that is, vitamin b9.

  Second is the lack of vitamin b12.

  The daily requirement of folic acid is 200-400g. The folic acid stored in the human body is enough for four months. As long as you consume fresh vegetables every day (overcooked or pickled vegetables will cause folic acid loss), there will be no problem.

   Vitamin b12, synthesized by microorganisms in nature, is the only vitamin that requires the help of an intestinal secretion to be absorbed.

   Its storage capacity in the human body is about 2-5mg, and the daily requirement is only 0.5-1g, and it can be absorbed repeatedly.

   Even a vegetarian who does not eat meat will take at least 10 to 15 years to develop vitamin B12 deficiency.

  Yan Yundang is not a vegetarian or only eats meat.

   His recipe is normal,

   That is to say, regardless of whether his megaloblastic anemia is caused by a lack of vitamin b9 or a lack of vitamin b12 (these two causes can only be identified through blood tests and other methods, and there is no condition now),

  There must be a problem with his gastrointestinal absorption function!

  If it is folic acid deficiency, it is small intestinal lesions that affect folic acid absorption.

  If vitamin b12 is insufficient, it is the lack of intrinsic factor in the stomach, which leads to vitamin b12 absorption disorders.

   "Suppose a person has a problem with his body, no matter how much salt he eats, he can't maintain the balance in his body, then he will be irreversibly weak."

   Li Ang said: "Similarly, Lord Yan has a problem with his stomach. No matter how balanced his diet is, his blood will still be insufficient."

   "Three energizers, the path of water and valleys, the beginning and end of qi. Does the lower energizer need to reduce turbidity, and the middle energizer need to be clear?"

   Qiu Jing on the side muttered to himself.

The lower burner and middle burner he mentioned refers to the "Huangdi Neijing Lingshu", the chest and abdomen are divided into three areas: upper burner, middle burner, and lower burner. The upper burner is above the diaphragm, the middle burner is in the stomach, and the lower burner is below the stomach. .

  Li Ang nodded, "Exactly."

   "Then what can Dr. Li do?"

   Yan Lin pursed her lips tightly, arched her hands respectfully, and asked seriously.

   "The way. It's hard to say."

Li Ang took a deep breath and said slowly: "The temporary method is to eat more cooked and not overcooked livestock offal, eggs, fish, pears, various vegetables including Langqiong Zhaoboling vegetables, Beef, pork, chicken, tofu and more.

  However, the probability of remission or even cure in the end is only about 30% to 40%. "

  Yan Lin was suffocated when he heard the words, subconsciously clenched his fists, and said in a deep voice, "Why is it only 30%?"

   "Gastrointestinal diseases cannot be accumulated in a day and a month."

  Li Ang said: "Once the disease is affected, it is extremely difficult to cure."

   "Okay Lin'er,"

  Yan Yundang interrupted his son who was about to ask again, and said slowly: "I, Yan Yundang, have fought in the battlefield for more than fifty years.

   When I was hungry, I gnawed on rotting horse carcasses, drank muddy sewage, even ate Guanyin soil and even the flesh and blood of demons.

   It is Haotian's blessing to live to the seventy-seventh year without having a gut piercing.

   Visceral disease, 30% of the hope of cure is enough. "

  He stared at Li Ang deeply, and asked, "Little Doctor Li, if this anemia is not cured, what will happen to me in the end?"

  “. Pernicious anemia will not directly cause death in the short term,

   But if it doesn't get better, you may experience persistent fatigue, lethargy, numbness in hands and feet, and jaundice. "

   Li Ang said in a low voice: "In the worst case, you may suffer from listlessness or even insanity."

   "Insanity. Derangement?"

  Yan Yun shook his head and then looked up, with a strange smile on his face, "Hahaha, when I was young, my fellow soldiers would always laugh at me as 'crazy Wu', 'crazy Wu',

  Unexpectedly, they all died of old age or battle, and I am really going to become crazy.”

"Father!"

  Yan Lin's eyes were red, and she choked up a sob, but met Yan Yundang's stern gaze, "Stand still! What does a man look like crying!"

  Yanlin raised her head subconsciously and stood upright, with the outline of her clenched jaw appearing on her cheek.

   Exactly the same as when I was young.

  Yan Yundang pursed his lips with complicated emotions, stared at Li Ang and said, "Thank you, Doctor Li.

   At least let the old man know why he will die. "

  Li Ang arched his hands, but stopped talking.

  In fact, the 30% cure rate he said is basically due to folic acid deficiency, which can be alleviated by a large amount of folic acid supplementation.

  If Yan Yundang is suffering from pernicious anemia caused by atrophy of the gastric mucosa and lack of intrinsic factor in the gastric juice, resulting in malabsorption of vitamin B12

   Then there is absolutely no way.

  Vitamin b12 is a red compound containing cobalt. Its atomic structure is extremely complex, with 181 atoms, which are distributed like magic felt in space.

  If you want to synthesize vitamin B12 artificially, you need to synthesize all parts of vitamin B12 first, and then connect them.

  With the current conditions, it is impossible to achieve it.

   "Yan Jiu, you go to the warehouse, and then deliver Dr. Li for me."

  Yan Yundang let out a long sigh, and raised his hand to let the old servant butler, who was also choked up, send Li Ang out of the house on his behalf.

  The old housekeeper went to the warehouse first, then returned to the hall, and led Li Ang to the side door in the backyard. Qiu Jing also accompanied him.

  When he reached the door, the old butler suddenly stopped and bowed deeply to Li Ang, "Thank you, Doctor Li."

"where."

Li Ang sighed softly, returned a salute, and said hesitantly: "If the Duke's government wants to use pigeons to conduct experiments according to my method, we might as well set up several groups and feed them with chaff, chaff mixed with a small amount of sugar, and chaff mixed with a small amount of pigeons." Salt chaff, sugar only, etc.

   Wait until some pigeons feel unwell before feeding brown rice.

   In order to test whether my statement is correct or not.

   As for the Duke’s condition, I will go back and check the medical books to find a solution. "

   "Thank you, Dr. Li."

  The old butler nodded gratefully, took out five Qianguan flying tickets from Liuguang Bank from his arms, and was about to hand them to Li Ang.

   "Old man, what are you doing here?"

  Li Ang refused to accept it, but the old housekeeper said: "This is the intention of the Duke, so please accept it.

  The notice posted by the Duke's Mansion in Chang'an has already stated that any prescription prescribed by a doctor can alleviate the disease, and reward Qianguan.

   If it can be cured, the reward is 5,000 Guan. "

   Repeated refusals failed, so Li Ang could only accept a thousand-pass ticket in the name of alleviating the illness, boarded the vehicle of the Duke's Mansion, and returned to Huaidefang.

  ——

  It was late at night, Li Ang was lying on the bed in the bedroom, looking at the starry sky outside the screen window, his lips were slightly pursed.

  In the evening, the servants of Duke Yan's mansion came again and brought the bay red horse that was fostered in the pasture of Xuegong.

  The bay red horse is a military horse, and the Yan family took the bay red horse out of the military for a while and gave it to Li Ang. It is currently kept in the stables of the hotel.

   This also made Li Ang's emotions more complicated—the treatment for pernicious anemia is to take vitamin B12 orally or intramuscularly every day, and take it for life.

  But whether it is artificially synthesized or extracted from the fermentation waste liquid of streptomycin, neomycin, chloramphenicol and other antibiotics, mature biochemical technology and modern chemical system are required.

  How difficult it is.

   "The times."

  Li Ang kept sifting through the many materials in the memory palace, but still felt that it was as difficult as reaching the sky, so he couldn't help but sighed softly.

  Chai Cuiqiao, who was already asleep on the bed on the other side of the room, turned over, dreamed of something, and muttered: "The time is calling"

  Hey, you girl stole my usual speech, right?

  Li Ang glanced at Chai Cuiqiao who was wrapped up in a ball, laughed dumbfoundedly, and shook his head.

  The era he mentioned refers to the lack of biochemical foundation and chemical industry foundation,

   also refers to the concept.

  ‘Blood transfusion therapy, in theory, can indeed temporarily relieve a small part of the symptoms of pernicious anemia patients,

  But it cannot fundamentally treat megaloblastic anemia.

   In addition, it is also a question of whether it is effective for the master martial artist to accept the blood of ordinary people, and the risk of blood agglutination must also be considered.

the most important is,

  Yu Guo pays attention to the parents who pay attention to the body, hair and skin,

  Drawing blood from other people and transfusing it into the body, will it be considered the same demonic behavior as that of the Demonic School in the former Sui Dynasty?

   Those demons also like to play with blood. '

  Li Ang thought silently: 'This is a human being, not a military horse or a pig.

  If the news of the effectiveness of blood transfusion therapy spreads, it will be distorted in those remote and backward areas where the news is sluggish.

   There may even be fools who think that drawing blood is equivalent to drawing life and longevity, and taking other people’s blood can extend their own life, so they take the initiative to harm others’

  Li Ang doesn't have too much expectation for the overall medical knowledge of Yu people - after all, there will be fools who believe that eating the buttocks of relatives can cure tuberculosis and other diseases.

   Xuegong, only Xuegong can develop the chemical industry that Li Ang wants as soon as possible,

  Only with the authority and resources of the academy can we reduce the harm that may be caused by misinformation in the process of promoting medical knowledge.

   "Calculate the time, the school retest, it won't be long"

  ——

  Time passed quickly, and in the blink of an eye, it was the midsummer of July, the day of the school's re-examination.

  Since there were only 5,000 students participating in the re-examination, the location of the examination was adjusted to Honglu Temple, Taichang Temple and Sinong Temple within the imperial city wall.

   Li Ang stood in the shadow of the imperial city wall, waiting to enter.

  Same as last time, the position order of the candidates is disordered,

   Not far away, Song Shaoyuan had a serious face and muttered something, as if he was carrying something.

  Zhai Yiming nervously kicked the curb lightly, chatting with Yang Yu who was also nervous.

   Even Ji Linglang, who has always been calm, turned out the book and glanced at it in a short gap.

   As far as the eyes can see, the students who are not nervous at all seem to be only herself and He Fanshuang standing in the corner—she stands alone, exuding the indifference of strangers all over her body.

   It's strange to say, but with the enthusiasm of the citizens of Chang'an, or the degree of good deeds,

   You should be able to quickly know the specific information of the first place in the school's first exam, such as birthplace, parents' occupation, family business, etc.

  But almost no one knew the information about He Fanshuang—even the fellow villagers from Youzhou who applied for the academy with her did not know her identity at all.

   "Maybe he is from a place other than Youzhou, deliberately filling in wrong hometown information to hide his identity?"

  A thought flashed through Li Ang's mind,

   But, is this necessary?

  No one with the five surnames will hide their identities.

  Even members of the Li clan enrolled in school under their real names—the Chang’an clan circle said it was big or small, and there were always people they knew, so there was no need for that.

   "Brother Li, Li."

  Yong Hongzhong's voice came, and Li Ang turned his head to look, and saw Yong Hongzhong standing behind him, clasping his hands and smiling.

   "Oh, Hong Zhong."

   Li Ang smiled. He didn't like the so-called Princess Le'an very much, but he didn't mean anything to Yong Hongzhong. "Have you been dizzy lately?"

   "No, no more."

  Yong Hongzhong said with a smile, "I exercise every, every day according to the method you said and said. I haven't made any mistakes or illnesses again."

   "That's good. How are you preparing for the retest?"

   Li Ang chatted casually with the other party, Yong Hongzhong's grades are quite good, policy questions, scriptures, and poems are all top-grade,

   But when he was in Yuke, he was afraid that his otolithiasis would recur and fall off his horse, so he didn't dare to speed up at all, so he rode slowly and passed the finish line, and he had to wait for Ding, who was in the last place.

  In the last preliminary test, the comprehensive score was ranked 60th.

   While the two were chatting,

   "Hong Zhong."

  The voice moved from far to near, Li Ang and Yong Hongzhong turned their heads to look, but saw a group of luxuriously dressed Wuling youths walking over.

  The leader was Qiu Jinghuan, the eldest son of the official servant's family, and he didn't see Pei Jing.

   "Why are you here? I've been looking for you for a long time."

  Qiu Jinghuan patted Yong Hongzhong on the shoulder, turned to look at Li Ang, with a weird smile on his lips, cupped his hands and said, "Yongjiafang, Qiu Jinghuan."

  Li Ang cupped his hands, and replied calmly, "Li Ang of Weizhou."

   "Hey, it turned out to be Brother Li Ang, who was second in the first test and made a big splash in the imperial department."

  Qiu Jinghuan grinned, exchanged glances with his companions around him, deliberately pronounced the word Li Ang quickly, and pronounced it in cool words, "Since brother Li Ang knows Hongzhong, he is my friend.

   Everyone should get closer in the future. "

"oh."

   Li Ang's attitude is still indifferent, he is not surprised by Qiu Jinghuan's inexplicable hostility - it is not only because of the first test, but also because the son of the official minister who was born in Yongjiafang, and the Le'an princess have been neighbors since childhood.

  According to Bao inquired about Yang Yu, Qiu Jinghuan was one of Princess Le'an's suitors.

   "Hachiro, bring the present."

   Qiu Jinghuan beckoned, and the companion beside him immediately brought two books,

  He took the book and handed it to Li Ang with a smile, "It's a small gift, I hope Brother Li Ang doesn't mind."

  The two books are "A and B Acupuncture Classics" and "Qianjin Yifang·Forbidden Scriptures", which are antique and the paper is yellow.

  Yong Hongzhong looked at the medical book, frowned involuntarily, pursed his lips slightly, a little angry.

  It is not a secret that Li Ang is a doctor, and it is not a good intention for Qiu Jinghuan to send two medical books—"Qian Jin Yi Fang·Jing Jing" records the law of cursing and banning,

   And cursing ban. Although it was once an official subject of the Imperial Medical Bureau,

   But in essence, it is primitive witchcraft, which uses dancing, praying, and singing to dispel the curse attached to the patient and "cure" the patient.

  The method of cursing and prohibiting is a product of ignorance and backwardness of medicine. It is a product of the inability of existing medical techniques to cure diseases and has to resort to ethereal witchcraft.

  Over the past hundred years, with the deepening of the research on heterogeneity in the academy, the forbidden spells derived from primitive religions are also declining and are about to die out—even the imperial medical department plans to abolish the forbidden spells.

   Qiu Jinghuan sent this book just to ridicule and ridicule.

  If you are not a good look, you are a good doctor. Be a good doctor.

  The youths in fancy clothes who followed Qiu Jinghuan laughed lightly,

   And Leon.

"hehe."

   Li Ang shook his head and smiled, rather than being angry, it was more funny.

  This kind of atmosphere where the boy is doing everything possible to attract the attention of the girl he likes, while the companions next to him follow suit.

  Familiar yet unfamiliar, close yet distant.

  dangdangdangdang—

  The Haotian bell rang through the imperial city. All the scholars raised their heads, put down their books, and walked into the examination room under the guidance of officials from the Ministry of Rites and teachers from the academy.

   "The medical book will be waived."

   Li Ang waved his hands with a smile, ignored Qiu Jinghuan and the others, and strode towards the examination room.

   Friendship push book!

   "After the Immortal World Dies": This is a final world where the immortal world has already disappeared.

   The world is gloomy, myriad dharmas disappear, time and space are disordered, and weird evils frequently appear.

   Only relying on the high walls of the prefecture city to gather the blood of the people, and using the power of the holy light of the **** statue to ignite a raging fire, can one or two be resisted.

   "Begging for work." After Kou Lin crowned the ceremony, he walked silently.
