There are two kinds of human bone marrow, one is called red bone marrow, which is found in the bone marrow cavity of flat bones and irregular bones such as human skulls, sternums, ribs, vertebrae, and clavicles.

There is also a type called yellow bone marrow, which is mainly concentrated in the long bones of the body, such as the ulna and radius on the arm and the femur tibia on the leg.

Of these two types of bone marrow, only the red bone marrow has hematopoietic function, and most of the yellow bone marrow is fat, and only when the person is highly anemic or has a large amount of blood loss, it will be converted from yellow bone marrow to red bone marrow to enhance hematopoietic function.

The bottle of bone marrow fluid he brought now came from the femur of a thigh, which had nothing to do with blood except for detecting DNA, so it was useless for Durin to drink it, and he still had to rely on the power of scientific instruments.

After about half an hour, Durin finally took a test sheet and walked out of the testing room.

"The results are out, the deceased is a man, the DNA sequence is on this piece of paper, I will send the electronic version to Lao Shui when I go back, you have the DNA information, it will be much easier to confirm the identity of the deceased. ”

"Okay, thank you Lao Du!" Li Xian put the report sheet in his bag and was about to go out.

"Wait a minute, didn't you go to the nearby village and ask, is there anyone missing?"

"Hey, why didn't you ask? I asked all the surrounding villages, and everyone said that no one was missing. Now we all suspect that it may be a rogue crime. ”

"Okay, let's go back quickly with the results, and then look for someone, and come to me again if you need me somewhere. ”

Three days later, Li Xian called Du Lin and asked him to hurry to the criminal police team.

"Lao Du, you are here. ”

"What's the matter? What's the matter?"

"Remember the case I told you about two days ago?"

"Remember, the case where only one thigh bone was found, and the identity of the deceased was confirmed?"

"I underestimated me too much, not only was the identity of the deceased confirmed, but even the suspect was arrested. ”

"Then what are you looking for me for?

"That's the case......"

During the first round of police investigations, several surrounding villages said that there was no one at home, and even family members who were not at home were all working in the city, but they did not verify every person who went out to work by phone.

After the police obtained the DNA information of the deceased, the second round of investigation focused on the homes of people who claimed to be working outside, and extracted the DNA of relevant personnel for comparison with the deceased.

Sure enough, in the second round of platoon, the police learned that a villager named Chen Yuan in Daqiao Village was not at home twice, and his wife Yu Guifen said that Chen Yu'an had gone to work in other places, and according to his neighbors, Chen Yu'an's rheumatism was very serious and it was impossible to go out to work.

So the police extracted the DNA of Chen Yu'an's two married daughters, compared it with the DNA of the deceased, and confirmed that the deceased was Chen Yuan, so Yu Guifen, who falsely claimed that Chen Yu'an was working in other places, was suspected of committing a major crime.

When the police went to arrest Yu Guifen, Yu Guifen drank the pesticide that had been prepared, of course the police would not just let her die, so they immediately took her to the county hospital to wash her stomach, and after seeing that the situation was stable, she took her back to the city bureau.

After talking about the situation, Li Xian said: "I came to you, mainly to let you see what kind of pesticide she was drinking, and whether she would be fine after washing her stomach." ”

"What about the pesticide bottles?" asked Doolin.

"You're not talking nonsense, if there's a pesticide bottle, I'll look for you? With that, he pulled out a bag of evidence, which contained a bottle of pure water, and a little bit of blue-green liquid in it.

Du Lin frowned, he didn't have many blue-green pesticides in his impression, I hope it wasn't that one.

Put on the gloves, open the evidence bag, carefully unscrew the cap, sniff at the mouth of the bottle, and sigh.

"How much did she drink?"

"Not much, just one bite. ”

"How long after washing the stomach. ”

"From their village to the county seat, we drove all the way to the county seat for more than 20 minutes, so it should be about half an hour after drinking pesticides. ”

Durin sighed again, "How's she doing now?"

"The state is okay, but I have been nauseous a few times, there is vomiting, and the vomit is bloodshot, I guess it hurt the gastric mucosa during gastric lavage. ”

"Don't talk nonsense if you don't know, it's not because of that," Durin looked down and thought for a moment, "Can I meet her?" "It's okay to see her, but you tell me if it's okay." ”

"Just listen along. ”

The information shows that Yu Guifen is 60 years old, but the real person is much older than her actual age, and people believe her when she is 70 years old.

Durin sat across from her and asked very seriously, "Do you know what you're drinking?"

"Yes, paraquat. ”

"Do you know how toxic paraquat is?"

"You know, if you die in one bite, you can't save it. ”

Li Xian sat up straight on the side of a spirit, pulled Du Lin and walked out.

In the corridor outside the interrogation room, Li Xian asked: "I have heard of this pesticide, and I also know that this thing is incurable, but can you think of a way to save her life, we have a preliminary understanding of this case, this woman's crime does not lead to death." ”

Doolin: "Can you turn a hard-boiled egg back into a raw egg?"

Li Xian was stunned, "Of course not, no one can do this." ”

Du Lin pointed to Yu Guifen in the interrogation room, "She's a hard-boiled egg, paraquat can cause completely irreversible damage to her lungs, and there is no antidote to this kind of thing, and it is quickly absorbed by the body when drunk."

If I can really find a way to save her, the World Health Organization will have to erect a 10-meter-high statue of me in front of their office building, and the first page of all future medical textbooks will have to be my photograph, and I will be the one who will enter the history textbook alive, do you believe it?"

"Then, it's hopeless?" Li Xian said dejectedly.

Doerin shook his head, "Paraquat 20% solution orally of less than 10 ml, even if the stomach is lavaged immediately, it will cause lifelong damage to the lungs, and after half an hour, the lungs will be severely fibrotic within 7-15 days, and the mortality rate will ...... 100%! Oral administration of more than 10 ml, basically no rescue value.

You said before that she drank a sip, and the person's sip was about 30-35 ml, and she herself had already sentenced herself to death, and she would be executed within ten days, and she didn't even have a chance to change the sentence. ”

"Then I think she's in good shape. Li Xian glanced at Yu Guifen in the crack of the door.

"Let me tell you about a case my teacher told us about when I was in school. ”

Du Lin sat on a bench in the hallway, and Li Xian also came over to sit down.

"There was a guy whose wife was cheating, and he couldn't think about it, so he bought 100ml of paraquat on the Internet and drank it, and regretted it because it was too irritating and too unpalatable.

Then he called 120 for help, and when he was sent to the hospital, almost half an hour after he drank the medicine, the hospital heard that he had drunk paraquat, and drank 100 ml, so he basically gave up the treatment.

But his own desire to survive is quite strong, insisting on letting the doctor rescue him, what if the online buy is a fake medicine? The emergency doctor also made sense when he heard it, so according to the conventional method, gastric lavage, activated carbon adsorbent, hemoperfusion and other measures were all put on, and then directly entered the ICU.

But unfortunately, this man met a conscientious seller, and the medicine was real.

In the days that followed, his mouth, tongue, pharynx, and esophagus began to fester, and his swallow was painful, and he had to eat cold food to reduce the pain.

He began to breathe rapidly, wheezing, lung CT showed that his lungs were no longer fibrotic, but there were interstitial exudation-like changes in the lungs, to put it bluntly, the alveoli were basically dead, the blood oxygen content continued to decrease, and inhaling high concentration oxygen can only ensure that the blood oxygen content is about 85%, while the value of normal people is more than 95%.

After six days in the hospital, he accepted the doctor's advice, stopped treatment, and was taken back to the community hospital by his family, where he died of lung failure two days later.

Before he died, he forgave his cheating wife. ”

"Poor man......" Li Xian's tone was heavy.
