Metropolis: My IQ is 300

Chapter 130

Chapter 125 Chen Fan, your birthday, let me give you a plane (for subscription, fifth)

The old father and mother’s thoughts are that they are happy in their hearts, and their silly son has finally learned to confess with the girl.

In the morning, Chen Fan habitually gets up early, Tao Yaoyao is by her side, sleeping peacefully.

After finishing his thoughts, Chen Fan stretched.

Checked the news.

“If the retina can be artificially cultivated, using genetic technology, do you support it? 》

“The premise of rebuilding the light is to use genetic technology, what do you think? 》

“Is it good or bad? In order to see the light, open Pandora’s Box? 》

Chen Fan knew that this was laying the groundwork.

In the future, it may be guided gradually according to the fishing vessel.

It was unprepared before, what suddenly appeared was too unbelievable, and now everyone has accepted it.

The door was pushed open. Chen Fan looked at Saudi Arabia standing at the door and said, “How did you come?”

“The plane made overnight, I applied for the conditions, and then I came over, how about it, hahaha, my good brother, I am the first one.”

Chen Fan’s parents walked out and looked at people abroad, a little surprised, and didn’t know what to say.

“Yes, yes?”

Saudi Arabia took out the headphones and said, “You take them.”

Soon, the two old people could understand the conversation.

“Come on, this is a good thing, Chen Fan is your birthday today, do you have anything you want to eat?”

“There is nothing to eat, but there should be a lot of people coming, or else, kill a pig.”

Hahaha, this idea is good.

There are still some people in the village willing to help. After Chen Qianqian saw that he might become a pig killer, he immediately felt that Chen Fan was torturing himself.

How could this guy let himself be a soldier to kill pigs?

fuck.

There were a lot of guests. Surprisingly, the governor also came and gave Chen Fan a long life lock.

The little yard gradually became lively.

Everyone found a place to sit down.

“How do I feel, I feel like I have a big birthday.”

Hahaha, Tao Yaoyao laughed infrequently, and then seemed to think of unhappy things again, so she changed her mind and ignored Chen Fan.

“My brother, what’s the matter with you, have you quarreled?”

“No.”

“So, are you sure about the relationship?”

“Yes, she is my girlfriend.”

Ha ha ha ha.

Saudi Arabia said: ‘I think, I know where the problem is, but I can’t tell you because the core of the problem is weird and you haven’t grown up yet. ’

“I think you are making fun of me.”

A man in white clothes appeared at the door, walked in with something, and took the initiative to shake hands with Chen Fan.

Qiu Hua was behind him.

Li Fansheng, a knife in domestic ophthalmology.

“Chen Fan, happy birthday to you.”

“Thank you, you are here, I have something to talk to you.”

“Uh, all right.”

The two of them entered the working state again. At first, Tao Yaoyao wanted to persuade, but finally gave up.

Anna came late, and when she arrived, she looked at the amulet on Tao Yaoyao and said, “You are done?”

“Yep.”

“Then what?”

“What then?”

This is not right, Anna said: “I calculated, if you become lovers, then today, you can’t go out, don’t think I don’t know your physical condition.”

“So what? What do you want to express?”

Puff, hahahaha.

Anna seemed to have thought of something and said: “No, Tao Yaoyao, no, really no, you don’t have that.”

“Don’t worry about it. We are pure love. People with dirty thoughts like you don’t deserve to understand.”

Chen Fan didn’t bother to take care of the girl’s secret here, now he is writing his paper.

I wrote it last night, and I need Li Fansheng to optimize it in the future.

“This is… the precautions for artificial cornea cultivation, and the development history?”

Chen Fan nodded.

“You help me optimize.”

“Here, change a material, choose hydroxyapatite

Hydroxyapatite (HA) is made of natural coral reef materials through inorganic treatment. The main chemical component is Ca10(PO4)6(OH)2, which is similar to the main inorganic component of human bones. It is stable in body fluids. The pore structure is similar to the Harvard system of human bone, with internal micropores connected to each other. This composition and structure make it highly biocompatible, non-toxic and non-antigenic. Fibrovascular tissue can grow into its inline micropores, improve the nutrient supply of the tissues before and after the implant, and increase the firmness of the contact between the implant and the recipient tissue, thereby reducing the chance of infection, necrosis, and injury. It is also stable in nature, light in weight, and less irritating and oppressing the surrounding tissues.

Chen Fan nodded and said, “But there is still the possibility of rejection.”

Li Fansheng said: “In fact, the development of artificial cornea is already very good, but the rejection problem cannot be solved. It can only be dealt with with a small probability. Moreover, the cost is high, and the follow-up plan was finally abandoned by everyone. .”

Ugh.

Chen Fan sighed and said, “If I can, I don’t want to take this matter.”

“No way, you don’t accept it, no one can accept it, I still hope you can accept it.”

Chen Fan wrote another data and said: “What about this?”

“Polymethylmethacrylate

After long-term clinical application, polymethyl methacrylate is an ideal optical center material. It has a high light transmittance (92%), a refractive index of 1.491, stable performance, and is very resistant to aging and environmental changes. High resistance, no biodegradability, resistance to acid, alkali and organic solvents, light weight, not easy to break, strong plasticity, and easy to process. As an ideal optical material, PMMA also has certain shortcomings: high hardness, which is not conducive to measuring intraocular pressure after artificial cornea implantation. It has limited tolerance to YAG laser and is easily damaged by YAG laser, making it difficult to treat the posterior membrane after implantation of artificial cornea, and the release of monomer after laser has biological toxicity. Can not be sterilized by high pressure and heated steam. Surface epithelial cells have poor adhesion and cannot form continuous corneal epithelium. There are risks of latent infection, leakage, and corneal lysis after surgery.

Or not.

Chen Fan rubbed his temples with a foggy expression on his face.

“So, I must come, right?”

“Yes.”

At this time, the door opened again, and two strangers, Charlie and Toss, also rushed over.

Chen Fan was surprised.

“What are you guys?”

“Dear Chen, I am naturally here to celebrate your birthday.”

There was a smile on Charlie’s face, which made Chen Fan’s heart a little relieved.

Toss said, “Talk?”

“OK.”

Toss called Chen Fan aside and said, “There is something, I have to tell you, the price is out, maybe you are not very satisfied, we estimated the price, it is about 150,000 yuan, this is your China Money.”

“But I can control the cost at four or five thousand.”

Toss said: “You are wrong, your cost is 300,000, and your purpose of selling 150,000 is to see the light for more people.”

“This is lying, you are a scholar, how can you make me lie.”

Toss really wants to slap Chen Fan now, why can’t he understand?

“Well, you say, what other materials are you OK?”

Fluorocarbon polymer.

Ha ha.

Toss explained: “Your biology, your basics are really too poor. I feel very embarrassed now. I didn’t expect that the one who solves biological problems will be a layman. Does our biology really need Can you solve it with physics and mathematics?”

Chen Fan shrugged and said that this is also something that can’t be helped.

“First, Lamberts et al. [10] recommended Proplast, a porous material, PTFE, fluorocarbon polymer and glassy carbon, as a peripheral stent for artificial cornea. This material is hard, rough, has good wettability, and has stable properties. , Easy to process, porosity 70% to 90%, pore size range 100 to 500μm. White et al. [11] reported the use of Proplast as the peripheral part, PMMA as the central optical zone of the penetrating artificial cornea animal experiment, postoperative artificial cornea stability In the early stage, fibroblasts grew in, and the longest survival time was more than 3 years. The other two soft fluorocarbon polymer materials, namely Impra and GoreTex [12], both belong to expanded polytetrafluoroethylene. Ethylene (expandedpolytetrafluoroethylene, ePTFE), the same physical and chemical properties, white, soft, smooth, porosity 77%～82%, pore size range 18～22μm, water absorption; the difference between the two lies in the fiber orientation and hardness, and the Impra fiber is single Going forward, the arrangement is orderly, which is conducive to the growth of fiber cells; the disordered arrangement of GoreTex fibers reduces the effective pore area and affects the growth of fiber cells 0…”

“Yes, so many advantages, then this can be replaced, why, gene training can be reduced.”

“That’s why I said, your bio is zero points.”

“why?”

“Legeais et al. [13] compared and observed the histocompatibility of the above three materials after implantation of the corneal lamellar. During the observation period of 4-8mo, it was found that only Impra showed better histocompatibility and stability. The physical examination showed that fibroblasts grew into the micropores and secreted collagen. Moreover, 1mo after implanting the white Impra into the rabbit cornea, the material gradually became transparent. Presumably due to the collagen secreted by the intercellular substance and fibroblasts filling the micropores The material has the same refractive index as the cornea, which reduces light scattering and increases transparency. Unfortunately, this degree of transparency does not meet the requirements of being an optical center. In short, the characteristics of the material include thickness, hardness, and micropores. The pore size, fiber orientation, etc. affect its stability after implantation.”

Chen Fan said helplessly: “So according to your statement, the optics is not up to standard?”

“Yes, do you want to see that those who treat eyes will see a muddy world in the end? I think you don’t need this either.”

Sure enough, it is not so easy.

“Do I have to open a pharmaceutical company? I have opened a car company now, and I am the top car company. I am currently looking for factories and so on.”

“It’s okay, there are not a few people who open multiple companies.”

“But, I don’t have so much time and money. I don’t lack. There are many things I want to do, rockets, 5g algorithms, and even the more telling VR in the future, mode space, etc., as well as freeing my hands. I have to do it, I want to do it.”

“Aren’t you taking a rest? If you are on the right track, isn’t it all right?”

“But I don’t have time now.”

Damn, how can this kid make no sense?

Tao Yaoyao came over, and Chen Fan told Tao Yaoyao about it without hesitation.

Tao Yaoyao looked at Toss and proactively apologized and said: “Sorry, Chen Fan may not have made it clear. I think Chen Fan can start this company.”

“Peach? I know you, you keep talking.”

“The core of your problem is nothing more than the need for a person to start a company, and the person who starts the company must still have contact with Chen, and he needs everyone’s or even direct approval.”

“Yes, your understanding is correct. This technology is Chen’s. If you change someone else, I really can’t think of the price.”

Tao Yaoyao said: ‘I think, I thought of a person, he really can. ’

“you say.”

“Li Fansheng, don’t forget. After this technology is implemented, ophthalmologists will need to be unemployed. Where is the new place to go? I think this is a big problem? Although they are needed for nursing care, their wages have fallen. They won’t accept it either. I think that Li Fansheng leads people to start a company, which is the most appropriate.”

“I refused. I didn’t participate in the whole process.”

Chen Fan said: “You must come.”

“I can come. I’ll take five percent, not three percent, no, percent, forget it, you can pay me six thousand wages a month, I think it’s enough.”

Chen Fan frowned, Qiu Hua left with Li Fansheng in his arms.

“Leave it to me, I will deal with the contract.”

Toss looked at Tao Yaoyao, gave a thumbs up, and said: ‘You are really an indispensable person for Chen Fan and a destined lover. ’

This old man is so cute. At this time Tao Yaoyao felt that Toss, he was really nice.

“Then I can post this technique?”

“Send, you must send, and the whole world has to send, but you need to study a mechanized production mode by yourself, don’t tell me, you can’t do it.”

“I hate the useless increase in work. I don’t want to make this money.”

“If you don’t make money, you have to make money. I’m just stuffing it, and I will put this money in your arms.”
