Chapter 69
Li Ang browsed through the information in the memory hall in his mind, and continued: "Have you ever seen a general who has not been able to eat salt for a long time?"

"Of course I did."

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

No matter how strong a man is, if he can't eat salt for a year and a half, he will become extremely weak, unable to mount a horse or lift a knife. "

"That's the truth."

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

Once you eat less, or can't eat, you will become weak and even sick. "

"Balance of yin and yang, five elements, qi, blood and body fluid?"

Yan Lin nodded. As a martial artist in the Innate Realm and General Youjinwu, he grew up in the army since he was a child.

What Li Ang said had some similarities with the method of body refining taught by the military, but it was not difficult to understand - in the early stage of body refining, prescriptions and medicated baths should also be used.

"Can"

Yan Lin frowned and said, "The dishes my father eats are all normal, with a balance of meat and vegetables.
During this time, under the advice of the doctor, he stopped drinking alcohol. "

"The dishes are normal, but the problem of the king is the stomach."

Li Ang said helplessly.

There are two possibilities for Yan Yundang's megaloblastic anemia. One is a lack of folic acid, namely vitamin b9.

The second is the lack of vitamin b12.

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

And vitamin b12, synthesized by natural microorganisms, 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 to 5 mg, and the daily requirement is only 0.5 to 1 g, and it can also be repeatedly absorbed.

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 usually only eats meat.
His recipes are 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, etc., there are no conditions now),

There must be a problem with his gastrointestinal absorption function!
If folic acid is insufficient, it is a small bowel disease that affects folic acid absorption.

If it is vitamin b12 deficiency, it is the lack of gastrointestinal intrinsic factor, resulting in the absorption of vitamin b12.

"Suppose a person has a problem with his body and cannot maintain homeostasis no matter how much salt he eats, then he will be irreversibly weak."

Li Ang said: "Similarly, Duke Yan's stomach has a problem, no matter how well-balanced he eats, his qi and blood will still become insufficient."

"Three energizers, the road of water and valley, and the end of qi. The lower energizer needs to lower the turbidity, and the middle energizer needs to be activated?"

Qiu Jian on the side muttered to himself.

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

Li Ang nodded, "Exactly."

"Then what can Dr. Li Xiao do?"

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

"How. 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 Langqiongzhao Polengcai, etc. Beef, pork, chicken, tofu and more.

However, the probability that it can be alleviated or even cured in the end is only about [-]-[-]%. "

Yan Lin suffocated when she heard the words, clenched her fists subconsciously, and said solemnly, "Why is it only [-]%?"

"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 scales,"

Yan Yundang interrupted his son who wanted to ask again, and said slowly, "I, Yan Yundang, have fought in the battlefield for more than fifty years.
When I was hungry, I ate rotten horse corpses, drank sewage from quagmire, and even ate Guanyin soil and even the flesh and blood of demons.

It is Haotian's favor to be able to live to the old age without a rotten stomach.

For viscera disease, [-]% of the cure is hopeful enough. "

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

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

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

Li Ang said in a low voice, "In the most serious case, you may be lethargic or even insane."

"Mental. Deranged?"

Yan Yun was dumbfounded and then looked up, with a weird smile on his face, "Hahaha, when I was young, my fellow soldiers would always laugh at me as a 'wu madman' and a 'wu madman',
I can't think of them all dying of old age or fighting, and I'm really going to become a lunatic."

"Father!"

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

Yan Lin subconsciously raised her chest and raised her head, standing upright, her cheeks showing the outline of her clenched jaw.

Exactly the same as when I was young.

Yan Yundang pursed his lips with complicated emotions, stared at Li Ang and said, "I still thank Dr. Li Xiao.

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

Li Ang cupped his hands and hesitated.

In fact, the [-]% cure probability he said is basically a folic acid deficiency, which can be relieved by supplementing a large amount of folic acid.

If Yan Yundang suffers from gastric mucosal atrophy and lack of intrinsic factor in gastric juice, which leads to the malabsorption of vitamin b12, the resulting pernicious anemia
Then there is absolutely no way.

Vitamin b12 is a red compound containing cobalt, and its atomic structure is extremely complex, with 181 atoms distributed in a magic felt-like space.

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

Under the current conditions, it is impossible to achieve.

"Yan Jiu, go to the warehouse, and then send Dr. Li Xiao on my behalf."

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

The old housekeeper went to the warehouse first, then returned to the hall, and took Li Ang to the side door of the backyard.Qiu Jian also accompanied him.

When he reached the door, the old butler suddenly stood still and bowed deeply to Li Ang, "Thank you, Dr. Li Xiao."

"where."

Li Ang sighed softly, returned the salute, and hesitated: "If the imperial government wants to use pigeons to conduct experiments according to my method, you might as well set up a few more groups and feed them with bran skins, bran skins mixed with a small amount of sugar, and bran skins mixed with a small amount of sugar. The bran of salt, feeding only sugar, etc.

Wait until some pigeons are unwell before feeding brown rice.

This will test whether my statement is correct or not.

As for Guogong's condition, I will go back and check the medical books again to find a way. "

"There is Dr. Lao Li Xiao."

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

"Old man, what are you doing here?"

Li Ang refused to accept it, but the old housekeeper said: "This is what the prince means, so please accept Li Xiaolang.

The Duke's Office has already said in the notice posted in Chang'an that any medicine prescribed by a doctor can alleviate the symptoms and reward Qianguan.

If it can be cured, the reward will be five thousand. "

After repeated refusals to no avail, Li Ang could only accept a thousand-kuan flying ticket in the name of relieving his symptoms, got on the vehicle of the Guogongfu, 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 pursed slightly.

In the evening, the servant of the Duke of Yan's mansion came again and brought the jujube red horse that was fostered in the pasture of the Xue Gong.

The jujube red horse belongs to the military horse, and the Yan family took off the military registration and gave it to Li Ang after a little walk.

This also made Li Ang's emotions more complicated - the treatment for pernicious anemia is daily oral or intramuscular injection of vitamin b12 for life.

However, whether it is artificial synthesis or extraction of vitamin b12 from the fermentation waste liquid of antibiotics such as streptomycin, neomycin, and chloramphenicol, mature biochemical technology and modern chemical systems are required.

How difficult it is.

"Times."

Li Ang kept sifting through the many materials in the memory palace, and still felt that it was as difficult as going to the sky, so he couldn't help sighing.

Chai Cuiqiao, who was already asleep on the bed on the other side of the room, turned over, not knowing what she was dreaming about, and muttered, "The times are calling"

Hey, you girl steal my usual way of talking, right?
Li Ang glanced at Chai Cuiqiao, who was wrapped up in a ball, laughed dumbly, and shook his head.

The era he said refers to the lack of biochemical foundation and chemical industrial foundation,

Also refers to. concept.

'Blood transfusion therapy can theoretically temporarily relieve a small number of symptoms in patients with pernicious anemia,
But can not fundamentally treat megaloblastic anemia.

In addition, it is also a question whether the Grandmaster Realm Martial Artist accepts the blood of ordinary people is effective, and the risk of blood coagulation should also be considered.

the most important is,

Yu Guo pays attention to his parents who are physically and skin-friendly.

Will blood drawn from others and injected into the body be considered to be the same demonic behavior as the demonic sect of the pre-Sui period?

Those demons also like to play with blood. '

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

If the news that the blood transfusion treatment is effective spreads out, in those remote and backward areas where the news is delayed, I don’t know how it will be distorted.

There may even be fools who think that drawing blood is equivalent to drawing life, and taking the blood of others can prolong life for themselves, so they take the initiative to harm others.

Li Ang didn't have much expectations for the general medical knowledge of the people of Yu country - after all, there will be fools who believe that eating the meat of relatives can cure tuberculosis and other diseases.

Xue Gong, only Xue Gong 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 possible harm caused by false rumors in the process of promoting medical knowledge.

"Calculate the time, it won't be long before the school re-exams."

----

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

Since only [-] students participated in the re-examination this time, the examination site was adjusted to Honglu Temple, Taichang Temple and Sinong Temple within the imperial city wall.

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

Just like last time, the positions of the candidates were disrupted,

Song Shaoyuan, who was not far away, had a serious face and muttered words, as if he was carrying something on his back.

Zhai Yiming nervously kicked the curb with his foot and chatted with Yang Yu who was also a little nervous.

Even Ji Linglang, who has always been unhurried, flipped out the book and glanced at it for a while.

As far as the eye can see, the student who is not nervous at all seems to be only herself and the He Fanshuang standing in the corner - she stands alone, and her whole body exudes an indifference that strangers are not allowed to enter.

Strange to say, 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 No.1 in the first examination of the school, such as birthplace, parents' occupation, family livelihood, etc.

But almost no one knew the information about He Fanshuang—even the fellow villagers from Youzhou who came to apply for the Academy with her were completely unaware of her identity.

"Maybe it came from somewhere other than Youzhou, and deliberately filled in the wrong place of origin to hide your identity?"

Thoughts flashed in Li Ang's mind,
However, is this necessary?
The children of noble nobles with five surnames will not hide their identities.
Even the clan members of the Li family were admitted under their real names - the Chang'an clan circles said that they were not big or small, and there were always people they knew, so there was no need for that.

"Li, Brother Li."

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

"Oh, Hiroshi."

Li Ang smiled. He didn't like the so-called Le'an County Master very much, but he didn't have any ill will towards Yong Hongzhong. "Are you still dizzy recently?"

"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 or fallen ill again."

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

Li Ang and the other party chatted casually. Yong Hongzhong's grades were quite good.

But when he was in the imperial department, he was afraid that his otolithiasis would recur and fall off the horse's back, so he didn't dare to accelerate at all.

The comprehensive score ranked No.60 in the last preliminary test.

While the two were chatting,

"Hong Zhong."

The voice went from far to near, Li Ang and Yong Hongzhong turned their heads to look, but saw a group of Wuling youths in luxurious clothes approaching.

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

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

Qiu Jinghuan patted Yong Hongzhong's shoulder, turned to look at Li Ang, a strange smile raised on the corner of his mouth, and cupped his hands: "Yongjiafang, Qiu Jinghuan."

Li Ang cupped his hands and replied lightly, "Li Ang from Kuangzhou."

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

Qiu Jinghuan grinned, looked at his companions, and deliberately read the word Li Ang quickly and pronounced it as a cool word, "Since brother Li Ang and Hongzhong know each other, then he is my friend.

Everyone should get closer and closer in the future. "

"Oh."

Li Ang's attitude was still indifferent, and he was not surprised by Qiu Jinghuan's inexplicable hostility - not only because of the first test, but also because the son of the official servant who was born in Yongjiafang, and the Le'an County Lord were neighbors since childhood.

According to what Bao asked about Yang Yu, Qiu Jinghuan was one of the suitors of Princess Le'an.

"Hachiro, bring the present."

Qiu Jinghuan waved his hand, and his companion immediately brought two books.

He took the book and handed it to Li Ang with a smile, "Little little 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 yellowed.

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 - "Qianjin Yifang · Forbidden Scripture" records the method of curse and prohibition.

And cursing. Although it was once an official subject of the Imperial Medical Bureau,
But in essence, it is primitive witchcraft, through dancing, praying, singing, to expel the curse attached to the patient, to "heal" the patient.

The method of curse and prohibition is a product of ignorance that is backward in medicine. It is a product of the inability to cure diseases by existing medical techniques and has to resort to nebulous witchcraft.

Over the past hundred years, as the Academy's research on aliens has become more and more profound, the curse and prohibition methods derived from primitive religions are also declining, and they are about to die out - even the Imperial Physician's Office plans to cancel the curse and prohibition department.

Qiu Jinghuan sent this book to ridicule.

If you are not a good person, you will be a good doctor.Be a good doctor.

The youths in Chinese costumes who followed Qiu Jinghuan laughed lightly,
And Li Ang.
"Ha ha."

Li Ang shook his head and smiled, more funny than angry.

This kind of teenager does everything he can to attract the attention of the girls he likes, and the companions next to him follow the atmosphere.

Familiar yet unfamiliar, close yet distant.

clang clang-

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

"The medical book will be waived."

Li Ang smiled and waved his hand, ignoring Qiu Jinghuan and everyone, and strode towards the examination room.

　Friendship push book!

　　"After the Immortal Realm is Quiet": This is a final world where the Immortal Realm has already died out.

　　The sky and the earth are dark, all methods disappear, time and space are confused, and strange evils are frequent.

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

　　"Begging for work." After Kou Lianguan bowed, he walked forward silently.
