Chapter 862

Is it "vampire disease"?

Vampire disease, also known as porphyria, is a group of diseases caused by the lack of specific enzymes in heme biosynthesis pathway.

Heme is an iron containing pigment that participates in the composition of hemoglobin. There are many different enzymes involved in heme biosynthesis. Different enzyme defects can cause different porphyria, and then lead to a series of symptoms.

Clinically, it is also called purpura disease, which is divided into hereditary and acquired. It is mainly manifested in photosensitive dermatitis, abdominal pain and neuropsychiatric disorders.

However, porphyria was first discovered in the west, because patients were afraid of the sun and were diagnosed with ischemia. Some people mistakenly thought that taking blood could cure diseases, and then led to the story of vampires.

In fact, taking blood is not effective, but blood transfusion has a certain effect.

The main causes of porphyrin gonorrhea are drinking, estrogen, pesticides, dialysis or fatty liver disease.

But there are also genetic factors.

Guo Xiang talked to the patient's mother alone. She hesitated for a long time before being honest. She and her husband are cousins. They are close relatives.

I see. Xing Ming and Xu Wei looked at each other. It should be a genetic variation.

A woman's disease this time should be due to pregnancy. Too much estrogen in her body leads to the disease.

"If you want to make a diagnosis, just check your urine again." Guo Xiang said.

Go back to the ward and take the patient's urine.

"How?" Xing Ming asked, this is the first time he has been exposed to this disease.

"If you put this urine in the sun, the color of the urine of normal people will become lighter after four hours, while the urine of porphyria patients will become darker. Dr. Xing, if you don't believe it, you can take out your urine and have a try. " Guo Xiang said.

Xing Ming had a red face, but he still took urine. He really wanted to see if there would be any difference.

Put the urine in a transparent box and put it in the sun. They'll see it again in the afternoon. Sure enough, Xing Ming's yellow urine has become as light as water, but the patient has become as brownish red as soy sauce.

"Why?" Xing Ming asked.

"Because the porphyrin in the patient's urine reacts with light, it turns brown red." Guo Xiang said that in this way, it is more certain that the patient has porphyria.

To confirm the disease, Guo Xiang discussed with the patient's mother-in-law and mother that pregnancy must be stopped immediately, otherwise the patient's disease will become more and more serious.

The patient's mother-in-law was very angry, "divorce, divorce immediately, can't have children, and she's still a psychopath. This is cheating marriage!"

"In laws, we're not cheating on marriage. We didn't know our daughter had this disease before!" The patient's mother was in a hurry.

"I don't care. Anyway, we don't dare to have this daughter-in-law. Whatever you want to have an abortion, I'll call my son to divorce you tomorrow!" The patient's mother-in-law shook hands and left.

The patient's mother was very helpless. She didn't expect this. In the past, her daughter was a little delicate. She didn't expect such a serious disease.

But now it's like this. We can only beat the child first. The daughter's life is very important.

So Xu Wei gave the patient a palace clearing operation. The patient's condition was quickly controlled, and then he was supplemented with high sugar to reduce the production of porphyrin, so as to prevent recurrence.

After two days, the patient woke up and looked like a person who had nothing to do.

But she also knew her illness and that she wanted to divorce her husband. She was very depressed.

"Doctor, will my daughter get sick again?" The patient's mother was very worried.

"There is no cure for this disease. Try to avoid the sun in the future. Once she is exposed to the sun, her skin will feel pain and burning, her skin will be red, blistered or even ulcerated, and her mood will be unstable..."

"You can't drink, you can't eat anything with estrogen, and I'm afraid you can't get pregnant. Although she will be anaemic, it's best to do venous bleeding regularly..."

"Because there is too much iron in the blood, and then input some heme, which will be more stable." Guo Xiang said that she was also very helpless. There was no rule of law for the disease, especially this kind of heredity, which is a genetic defect.

The patient's mother's eyes turned red. "I hurt her. I shouldn't have talked to her father..."

Blame yourself for being too capricious and thinking that true love could be desperate.

It's not just saying that collateral relatives can't get married within three generations. It's really scientifically based.

Some people may say that so and so they know are not cousins. How can their children be all right?

This is a question of probability, but this probability is much higher than that of ordinary people. Close relatives marry and have far more defective children than normal people.

Some people's children are mentally retarded as soon as they are born, and even have several because of the marriage of close relatives.

If there are too many similar genetic genes in close relatives, the probability of genetic diseases increases, and the risk of some autosomal recessive diseases is much higher.

Therefore, marriage should be cautious. If you really want to be willful, don't have children, so as not to harm him (her).

After a period of time, the patient was discharged from the hospital after head surgery. It is unknown what happened to her and her husband.

Soon it was November, and it was very cold in the capital.

Guo Xiang broke his fingers and counted the days. His husband was coming back soon.

I'm looking forward to it.

On that day, an old man of about 60 came to work. His wife accompanied him.

"Sir, what's wrong?" Asked Guo Xiang.

As soon as the old man opened his mouth, his saliva flowed down, and his old face turned red.

"Let me tell you." His wife couldn't see it. "I don't know how. A few days ago, the corners of my mouth were always drooling, and my mouth couldn't close. As soon as I went to bed, I would drool and wet my pillow."

"I also said that this man is not old. Why is he so unclean? Who knows that he choked and coughed when he drank water. He couldn't drink water in. When he drank, it flowed out of the corner of his mouth and sometimes vomited out..."

"At first we thought we were just affected by the wind. Who knows, later we couldn't swallow anything. We couldn't swallow a little bit of a big piece. We had to vomit and take a small bite again before we swallowed it slowly. It was not easy to eat some rice."

"You see, people have lost so much weight in just a few days. Then they said, could it be a stroke? He was frightened. If he was paralyzed in bed, wouldn't life be better than death? Come and have a look. " Said the patient's wife.

Guo Xiang nodded as he listened and took the stethoscope. "Sir, let me show you."

Put the stethoscope in front of the old man's chest. I feel that my breathing and heart rate are very normal. I measured my blood pressure, but it's not too high.

"Sir, show me your tongue." Guo Xiang said.

"Doctor, aren't you a Western doctor? Why do you still look at the tongue coating? " Asked the aunt.

Guo Xiang smiled, "I'm not looking at the tongue coating, I'm looking at whether the uncle can control his tongue..."

Generally speaking, if a person has a stroke, his tongue will lean to one side and not center.

Because the muscles of the tongue are controlled by the brain. If the brain has a stroke and just damaged the nerve controlling the tongue, the tongue will be biased to one side and cannot be centered.
