Ask Sword

Li Ang browsed through the materials in the memory hall in his mind, and continued: "Have you ever seen a person who can't eat salt for a long time, the general?"

"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 doesn't 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 can't eat, you will become weak and even sick. "

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

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

What Li Ang said has some similarities with the body training method taught by the army, 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.

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

The 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 2-5 mg, and the daily requirement is only 0.5-1 g, 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,

In other words, regardless of whether his megaloblastic anemia is caused by a lack of vitamin b9 or 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 the absorption of folic acid.

If it is vitamin B12 deficiency, it is the lack of intrinsic factor in the stomach, leading 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 homeostasis, then he will be irreversibly weak."

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

"Three energizers, the road of water and valley, 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 still about to ask, and said slowly: "I, Yan Yundang, have fought in the battlefield for more than fifty years.

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

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

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

He stared deeply at Li Ang, 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 improve, there may be 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 was dumb and then looked up, with a strange smile on his face, "Hahaha, when I was young, my comrades in the army would always laugh at me as 'crazy Wu', 'crazy Wu',

Unexpectedly, they all died of old age or died in battle, and I really want to become a madman."

"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.

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

"Yan Jiu, you go to the warehouse, and then send off Doctor Li for me."

Yan Yundang sighed, 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 the 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 pigeons mixed with a small amount of sugar. Salt chaff, sugar only, etc.

Wait for the pigeons to feel unwell before feeding brown rice.

To test whether my statement is correct or not.

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

"Thank you, Doctor Li."

The old butler nodded gratefully, took out five Qianguan flying tickets from Liuguang Bank from his pocket, 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 Duke's intention, Li Xiaolang-jun will 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 Qian Guan.

If he can be cured, he will be rewarded with five thousand guan. "

After repeated refusals to no avail, Li Ang could only accept a thousand-pass flight ticket in the name of alleviating his 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 the Duke of Yan's mansion came again and brought over the bay red horse that was fostered in the pasture of the Xuegong.

The bay red horse is a military horse, and the Yan family took the 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.

However, 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 he 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 at the other side of the room, turned over, dreamed of something, and muttered, "The times are calling"

Hey, you girl stole what I usually say, right?

Li Ang glanced at Chai Cuiqiao who was wrapped into a ball, laughed dumbly, 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 martial artists in the master realm to receive blood from ordinary people, and the risk of blood clots must also be considered.

the most important is,

Yu Guo pays attention to the body, hair and skin of his parents,

Will taking blood from other people and transfusing it into the body be considered the same evil deeds as the demon sects in the pre-Sui period?

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 delayed.

There may even be fools who think that drawing blood is equivalent to extracting life and longevity, and taking other people's blood can prolong life for themselves, so they take the initiative to harm others'

Li Ang didn't have too much expectations for the overall medical knowledge of Yu people - after all, there will always 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.

"Calculating the time, it won't be long before the school retests."

————

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 this time, 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 a little nervous.

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

As far as the eye 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 an air of indifference that no one should 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 the first place in the school's first exam, such as birthplace, parents' occupation, family livelihood, etc.

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

"Maybe it's from a place other than Youzhou, deliberately filling in the wrong place of origin information to hide your identity?"

A thought flashed through Li Ang's mind,

However, is this necessary?

The sons of noble families with five surnames would not hide their identities.

Even members of the Li clan enrolled in school under their real names—the Chang'an clan circle is not big or small, and there are always people they know, so there is no need for that.

"Li, Brother Li."

When Yong Hongzhong's voice came, Li Ang turned his head 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 have any malice towards Yong Hongzhong. "Have you been 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 is your preparation for the retest?"

Li Ang and the other party chatted casually. Yong Hongzhong's grades were quite good, and his policy questions, scriptures, and poems were all top-notch.

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 across the finish line, and had to wait for Ding, who was in the last place.

The comprehensive score was ranked 60th in the last preliminary test.

While the two were chatting,

"Hong Zhong."

The sound came 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, who did not 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, with a weird smile on his lips, cupped his hands and said, "Yongjiafang, Qiu Jinghuan."

Li Ang cupped his hands, and replied indifferently, "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 Yuke."

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

Everyone should get closer and closer in the future. "

"oh."

Li Ang's attitude was still indifferent, he was not surprised by Qiu Jinghuan's inexplicable hostility - it was 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 princess had been neighbors since childhood.

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

"Hachiro, bring the gift here."

As soon as Qiu Jinghuan waved, his companion 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 yellowed.

Looking at the medical book, Yong Hongzhong couldn't help frowning, and 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. Although it was once an official subject of the Imperial Medical Bureau,

But in essence, it is primitive witchcraft, through dancing, praying, and singing, to get rid of the curse attached to the patient and "cure" the patient.

The law of curse and prohibition is the product of the ignorance of the backwardness of medicine, the product of the inability to cure diseases with existing medical techniques, and the product of having to resort to ethereal witchcraft.

Over the past hundred years, as the academy's research on aliens has become more and more in-depth, the curse-forbidden law derived from primitive religions has also been declining and is about to die out—even the imperial medical office plans to abolish the curse-forbidden department.

Qiu Jinghuan sent this book just to ridicule and ridicule.

If it is not a good look, it is 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 does everything possible to attract the attention of the girl he likes, while his companions follow suit.

Familiar yet unfamiliar, close yet distant.

clang clang clang——

The bell of Haotian resounded throughout 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 books 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 the final world where the immortal world has been extinct.

The world is dark, all 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 god statue to ignite a raging fire, can one or two be resisted.

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