There are two types of human bone marrow. One is called red bone marrow, which is found in the medullary cavities of flat and irregular bones such as the human skull, sternum, ribs, vertebrae, and clavicle.

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

Among these two types of bone marrow, only red bone marrow has hematopoietic function. Most of yellow bone marrow is fat. Only when the person is highly anemic or suffers a large amount of blood loss will the yellow bone marrow be converted into red bone marrow to enhance the hematopoietic function.

The bottle of bone marrow fluid we brought now came from a femur. Apart from detecting DNA, it had nothing to do with blood, so it was useless for Dulin to drink it. He still had to rely on the power of scientific instruments.

After about half an hour, Du Lin finally walked out of the testing room with a test sheet.

"The results are out. The deceased is a male. The DNA sequence is on this piece of paper. I will send the electronic version to Lao Shui later. Now that 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 into his bag and was about to go out.

"Wait a minute. Didn't you go to the nearby villages and ask if anyone has a missing person?"

"Hey, why didn't you ask? I've asked several surrounding villages, and everyone said that no one is missing. Now we all suspect that the crime may be committed on the run."

"Okay, take the results and go back quickly. Then look for someone. If you need me anywhere, come back to me."

Three days later, Li Xian called Du Lin and asked him to come to the criminal police team as soon as possible.

"Lao Du, you're finally here."

"What's wrong? What's so urgent?"

"Do you still remember the case I told you two days ago?"

"Remember the case where only one thigh bone was found and the deceased was identified?"

"You underestimated me. Not only was the identity of the deceased confirmed, but the suspect was also captured."

"Then why are you looking for me? The trial is over!"

"This is the situation..."

During the first round of police investigation, several surrounding villages said that no one was missing at home, and even family members who were not at home were working in the city, but they did not conduct phone verification on every person who went out to work.

After the police obtained the DNA information of the deceased, the second round of screening focused on the families who claimed that someone was working outside the home, and extracted the DNA of the relevant personnel for comparison with the deceased.

Sure enough, in the second round of investigation, the police learned that a villager from Daqiao Village named Chen Yu'an was not at home for both inspections. His wife Yu Guifen said that Chen Yu'an went to work elsewhere. According to his neighbors, Chen Yu'an

My rheumatism is very serious and cannot be treated at all

Can go out to work.

So the police extracted the DNA of Chen Yu'an's two married daughters and compared it with the deceased's DNA, confirming that the deceased was Chen Yu'an. Therefore, Yu Guifen, who falsely claimed that Chen Yu'an was working elsewhere, 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 let her die like that, so they immediately took her to the county hospital and had her stomach lavaged. After seeing that her condition was stable, they took her

Back to the city bureau.

After explaining the situation, Li Xian said: "I came to you mainly because I wanted you to see what kind of pesticide she drank and whether she would be fine after washing her stomach."

"Where's the pesticide bottle?" Dulin asked.

"You're not talking nonsense. If there is a pesticide bottle, why should I come to you to see it? It's in a purified water bottle, right here." After saying that, he took out an evidence bag, which contained a purified water bottle, and there were also

A little remaining blue-green liquid.

Du Lin frowned. There weren't many blue-green pesticides in his mind. He hoped it wasn't that kind.

Putting on gloves, he opened the evidence bag, carefully unscrewed the bottle cap, smelled at the mouth of the bottle, and sighed.

"How much did she drink?"

"Not much, just one bite."

"How long does it take to wash the stomach?"

"It took us more than 20 minutes to drive from their village to the county seat. Based on this calculation, it should take about half an hour for the stomach to be washed after drinking the pesticide."

Du Lin sighed again, "How is she doing now?"

"I'm in good condition, but I've been nauseous a few times, vomited a lot, and the vomitus has blood streaks. I guess the gastric mucosa was damaged during gastric lavage."

"Don't talk nonsense if you don't understand. It's not because of that." Du Lin lowered his head and thought for a moment, "Can I see her?" "It's okay to see her, but you should tell me if everything is okay."

"You'll find out if you listen along."

Information shows that Yu Guifen is 60 years old, but in real life she looks much older than her actual age. Some people believe she is 70 years old.

Du Lin sat opposite her and asked seriously, "Do you know what you are drinking?"

"I know, paraquat."

“Do you know how toxic paraquat is?”

"You know, one bite will kill someone, and you can't even save them."

Li Xian stood upright and pulled Du Lin out.

In the corridor outside the interrogation room, Li Xian asked: "I have heard of this pesticide, and I also know that it is incurable, but can you think of a way to save her life? We have preliminary understanding of this case, this

A woman’s sin does not lead to death.”

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

Li Xian was stunned, "Of course not, who is this?"

It can’t be done either.”

Du Lin pointed at Yu Guifen in the interrogation room, "She is just a cooked egg. Paraquat will cause completely irreversible damage to her lungs. Moreover, there is no antidote for this kind of thing, and it will be quickly absorbed by the body after drinking it.

If I can really find a way to save her, the World Health Organization will erect a ten-meter-high statue of me in front of their office building. My photo will be on the first page of all medical textbooks in the future. Can I be the person who enters the hospital alive?

People who read history textbooks, do you believe it?"

"Then it's hopeless?" Li Xian said in frustration.

Du Lin shook his head, "Oral administration of less than 10 ml of 20% paraquat solution will cause lifelong damage to the lungs even if the stomach is lavaged immediately. If the stomach is lavaged half an hour later, the lungs will undergo severe fibrosis within 7-15 days, leading to mortality.

...100%! Taking more than 10 ml orally has basically no rescue value.

You said before that she took a sip, and a human sip is about 30-35 ml. She has already sentenced herself to death, and it will be executed within ten days, without even a chance to change the sentence."

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

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

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

"There was a man whose wife cheated on her. He couldn't let it go, so he bought 100 ml of paraquat online and drank it. After drinking it, he regretted it because it was irritating and unpleasant to drink.

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

But his own desire to survive was quite strong, and he insisted on asking doctors to rescue him. What if the medicine he bought online was counterfeit? The emergency doctor heard that it made sense, so he followed the usual methods, including gastric lavage, activated carbon adsorbent, hemoperfusion and other measures.

I got everything done and went directly to the ICU.

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

In the following days, his mouth, tongue, pharynx, and esophagus began to ulcerate, and it was painful to swallow saliva. He could only eat cold food to reduce the pain.

He began to breathe rapidly and wheeze. The lung CT showed that his lungs were no longer fibrotic, but had interstitial exudation-like changes. To put it bluntly, the alveoli were basically dead, and the blood oxygen content continued to decrease.

High-concentration oxygen can only ensure that the blood oxygen content is around 85%, while the value for normal people is more than 95%.

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

Before he died, he forgave his cheating wife."
