From small clinic to medical empire

Chapter 215 Nature Has No Limits

For Liu Xiaonan's whims, Zhang Zifan could only express his blessings.

"Speaking of which, these human flies are amazing. Although they look like maggots, they have such healthy dining etiquette and secrete antibiotics to protect the host."

"Uh... Brother Zhang, the pot you touched is not a human skin fly..."

"That is……"

"That's really a maggot... a maggot that eats feces and carrion!"

"Fuck!"

Zhang Zifan quickly put down the maggot in his hand, "Xiao Nan, why are you raising this! I need disinfectant!"

"Don't worry, although in nature, the larvae of the hemp fly are the hosts of thousands of pathogenic bacteria, but the individuals raised here are very clean, just like the mice in the laboratory."

Liu Xiaonan explained with a smile, "Actually, the purpose of studying these flies is the same as that of studying human flies, that is, to breed larvae that specialize in eating fat tissue.

But at present, the success rate of human skin flies is higher, and the cultivation and evolution of these maggots has failed. They only eat necrotic and denatured tissues, and will not touch healthy tissues, and of course they will not eat fat. "

"Oh, that's a pity."

Zhang Zifan shook his head subconsciously, suddenly he noticed something, and asked, "Wait, Xiao Nan, you said that the maggots of these maggots only eat necrotic and degenerated tissues, and don't touch any healthy tissues?"

Liu Xiaonan nodded and said: "Yes, natural hemp fly larvae have such characteristics, and these species have been artificially bred, and the judgment of tissue composition is more accurate."

"Does the necrosis and degeneration you are talking about include fibrosis of lung tissue?" Zhang Zifan asked quickly.

Liu Xiaonan shook his head and said, "I'm not sure, but they don't eat fatty liver tissue, I've tried it."

"It's different, fatty degeneration is the appearance of excessive fat droplets in the cytoplasm, which is a reversible pathological change.

Pulmonary fibrosis is an end-stage change of a large class of lung diseases characterized by fibroblast proliferation and accumulation of a large amount of extracellular matrix accompanied by inflammatory damage and tissue structure destruction! "

Having said this, Zhang Zifan felt more and more that his idea was feasible.

However, although Liu Xiaonan had a thorough understanding of insects, he hadn't gotten started with histopathology.

In this case, Zhang Zifan immediately began to verify it through experiments.

Zhang Zifan asked Liu Xiaonan to go to the first floor and found an experimental guinea pig for him.

The normal experimental design, if you want to create a model of pulmonary fibrosis, you need to add an inducer to the environment where the guinea pigs are raised to make them slowly develop symptoms of pulmonary fibrosis, and then slaughter them.

However, Zhang Zifan has the [Eye of Deconstruction/Reconstruction]. It is not difficult to produce a small tissue sample of pulmonary fibrosis.

Moreover, Zhang Zifan could not directly execute the guinea pigs, but could only anesthetize the living guinea pigs, open the chest, and conduct experiments directly on the collapsed lungs.

Because according to Liu Xiaonan's introduction, when an animal or person dies, the flies can arrive at the scene within 10 minutes to lay eggs, and within one or two hours the eggs will hatch into maggots and start eating the corpse.

If isolated lung tissue from guinea pigs is used, it is very likely that the larvae of the flies will have an indiscriminate appetite.

In this case, the experiment is meaningless.

And using a living guinea pig, although the moment the chest is opened, its lungs will be compressed into a ball by the atmospheric pressure and lose its function.

But after all, there is still a long time before death.

As for whether the mouse right is not the mouse right, we can't control it for the time being.

……

Fortunately, he was full at noon, so Zhang Zifan built a guinea pig lung model in which fibrotic tissue and normal tissue were mixed together.

This was followed by hungry larvae of the flies.

Finally, the results of the experiment are very satisfactory.

This batch of artificially selected sarcophagus larvae can accurately select and feed on pulmonary fibrosis tissue without destroying normal tissue!

According to Zhang Zifan's guess, it may be that fibrotic tissue, like dead tissue, releases certain apoptosis transduction signals, or compiles certain special proteins, which are specifically recognized by the larvae of the sargassum fly.

But no matter what the principle is, Zhang Zifan feels that he seems to have found a chance.

As I said before, people have limits.

But nature has no limits.

Zhang Zifan picked up Liu Xiaonan through the protective clothing and said excitedly: "You are really my little lucky star!"

……

Sign the talk room.

"What? No, this is too scary, my family Mao Mao suffered too much!"

Hearing Zhang Zifan's completely unprecedented treatment plan, the patient's mother couldn't help but scream.

But he was held down by the child's father, "Shut up, you know nothing, listen to the doctor!"

It's true that Mao Jun was a bad gambler, but once the prodigal son turns around, he is the backbone of the family compared to his wife who can't figure it out.

Mortgaging real estate, raising money, and trusting doctors unconditionally, Mao Jun knew that this was the only thing he could do as a non-professional and as a family member of a patient.

As for whether he would entrust others to others, he could only do his best and obey the destiny.

In any case, Mao Jun had inquired about the deeds of Haoran Hospital and Director Zhang Zifan, and he believed that his choice was not wrong.

Zhang Zifan still noticed the father's change.

Maybe some men don't grow up all their lives. Only after experiencing a major blow can they mature overnight and understand what a man's responsibilities and responsibilities are.

"If you understand the risks of surgery and can accept the price of losing the ability to work and part of your normal life in the future, then please sign the informed consent."

Zhang Zifan thought for a while, then took out another document and said, "Although we are not a teaching hospital yet, you also know that your son's surgery is very meaningful, and we hope to keep the surgery images as teaching materials. Some of the images may also be viewed by non-professionals.

If you are willing to authorize our hospital to do so, there will be relevant reductions in the operation fee. "

"Okay! Dean Zhang, you can do it with confidence. Whether it succeeds or not, we as family members will not blame you."

Mao Jun took a deep breath and signed his name on both documents.

……

Since most of the toxic components in the patient's blood have been eliminated by dialysis, paraquat is currently mainly concentrated in the patient's lungs.

Removing the enriched paraquat and the formed fibrous tissue as soon as possible and with the least damage is the most important thing to maintain the life of the patient.

So without further ado.

At 7:30 p.m., the makeshift medical team was ready to start the operation.

Up to now, the child has lost his skin. Before the operation, he only asked Zhang Zifan one question: "Doctor, if the operation is successful, can I still play basketball in the future?"

Zhang Zifan shook his head, and replied truthfully: "I can't even compete in the Paralympic Games."

For some reason, at this moment, Zhang Zifan didn't want to tell a white lie.

People should bear the consequences of their choices.

Even if he is just a child.
