Chapter 489 Sharing Joy and 'Unexpected' Events (Please Subscribe)
The normal blood oxygen level in the human body needs to be above 95% in order to maintain normal bodily functions.

However, this takes into account the oxygen consumption needs of all organs in the entire body.

The lower limbs are far less delicate than organs such as the brain, heart, and spleen; in fact, the limbs are the most resilient.

Brain death can occur if brain tissue is deprived of oxygen for five minutes.

Fifteen minutes of myocardial ischemia can be fatal...

According to current understanding, complete ischemia of both lower limbs for up to six hours is considered a good indication for limb replantation.

This is still a complete lack of blood.

Locally, a microcirculator can achieve a blood oxygen level of 80%, which is sufficient to support the structural oxygen consumption needs of the lower limbs.

As for energy deficiency, there is no need to worry at all. The micro-circulatory device can complete the exchange of oxygen in the arterial and venous blood circulation, and can easily replenish various electrolytes and nutrients.

Furthermore, metabolic waste is excreted through a filtration device.

With an 80% blood oxygen level and adequate nutrition, maintaining the vitality of the lower limbs for several hundred hours is not a problem at all.

It took Nie Mingxian a full half minute before he let go of Fang Ziye and Wu Xuanqi's hands, and then the three of them laughed like children.

While looking at the resentful eyes of the experimental rabbit next to her, she also looked at the various data transmitted by the micro-circulator.

"Lower limbs, blood pressure, blood oxygen, heart rate..."

"Draw some arterial and venous blood to examine their metabolic structure," Fang Ziye said calmly, as he began searching for syringes.

There are definitely no professional venous blood collection devices here, because there is no need to use such high-end equipment at present.

The miniature circulator is equipped with a one-way valve for blood collection channels, which is to facilitate the collection and analysis of arterial and venous blood at any time.

Wu Xuanqi handed Fang Ziye and Nie Mingxian each a syringe to remove needles, saying, "You two, do this. You two made this device."

Wu Xuanqi can at most be considered a witness.

Before Wu Xuanqi arrived, Nie Mingxian and Fang Ziye had already brought the miniature modification device to its final stages, so Wu Xuanqi didn't dare to shamelessly claim that he was a participant.

At this moment, Nie Mingxian and Fang Ziye couldn't care less about Wu Xuanqi's feelings, especially Nie Mingxian.

I heard that when they were roommates before, Wu Xuanqi, that bastard, committed adultery in the room in front of Nie Mingxian.

After the blood is drawn, it is sent to the laboratory's "testing room" for blood gas analysis, which mainly analyzes the levels of electrolytes, lactic acid, ketone bodies, etc.

At this point, the focus should be on issues related to energy metabolism in the local tissues.

After delivering the two blood samples, Fang Ziye said, "Brother Xian, so the principle you proposed earlier—high-volume thrombolysis of the distal lower limb after amputation—is feasible."

Why is amputation necessary? Generally, it's due to severe proximal bleeding and severe embolism in the distal arteries, leading to poor blood flow.

If the lower limb remains in place, it will worsen blood loss, and the constantly returning veins will bring metabolic waste.

Amputation is a better way to stop bleeding and removes the necrotic lower limb stump from the patient's circulatory tissue.

“PCI is effective for coronary artery embolism. It is impossible for a high dose of local thrombolytic drugs to be ineffective.”

"Moreover, since it's a localized area after amputation, the margin for error is actually higher."

"We tried many times and finally found that several times or even twenty times the normal dose of thrombolytic drugs are safe after leaving the body."

“Furthermore, these drugs can be automatically ‘metabolized’ within a few hours,” Nie Mingxian said.

After saying this, Nie Mingxian plopped down again, leaned back in his chair, and sighed, "I guess I finally managed to get it done before leaving Han City."

"It's not considered a breach of contract, much less a case of leaving without a job."

Fang Ziye arrived last, so Wu Xuanqi and Nie Mingxian had probably seen enough, but Fang Ziye wasn't satisfied and was still looking carefully.

And they started taking photos from all angles.

This moment is undoubtedly of historical significance and deserves to be commemorated by all means.

This device, though small and modified, is undoubtedly Fang Ziye's greatest invention to date, without exception.

The development of techniques for destruction and functional reconstruction is not as meaningful as it.

Fang Ziye knew very well that it wasn't that his technology was particularly original. While modification and deduction of principles were certainly difficult, they couldn't compare to the development of the two techniques.

But its significance is greater than the two surgical methods because of its convenience.

Convenience is a factor that must be considered in any era and society.

From walking to taming horses and donkeys, humans broke through the limitations of individual speed, using the power of these tools to make their speed no longer limited by human instinct.

Then came the manufacture of horse-drawn carriages and donkey carts, which meant that people's ability to carry goods was no longer limited to the physical strength of an individual carrying heavy loads.

Are riding horses and donkeys difficult? Not really, they're definitely easier than taming wild horses and donkeys. Ordinary people can learn to ride them, which breaks down the barriers to entry.

Analogous to cataract surgery and functional reconstruction surgery, these are relatively high-barrier techniques. Based on statistical data from animal laboratories, mastering these techniques currently requires significant effort.

Only professionals who have mastered Level 4 debridement techniques can possibly grasp the intricacies of the process; otherwise, all efforts will be in vain.

The reason Fang Ziye was so certain was because his junior apprentice, Jie Han, after several setbacks, had returned to learning and practicing basic debridement techniques.

Jie Han's talent is not bad, at least comparable to Wang Yuanqi's. The reason why Jie Han has been unable to master the basics for so long is definitely not because he lacks talent, but because his foundation is insufficient.

The basics are very important...

Once such a miniature circulation device is available and successfully mass-produced, will Fang Ziye be the only one capable of performing limb transplantation?

Not!
Limb transplantation is actually an extension of limb replantation, except that the time window is much wider than that of limb replantation surgery.

Many patients can have their limbs amputated at lower-level hospitals and then be sent to higher-level hospitals for limb replantation!
Other hospitals, and even most prefecture-level city hospitals, can perform such limb replantation surgery.

What they lack is not technology, but the technology to preserve limbs intact.

After a limb is amputated at a lower-level hospital, they dare not attempt to replant the remaining limb, because if it doesn't survive, they'd be asking for trouble.

But the emergence of this miniature circulator has dispelled such concerns!

Instruments and tools can drive technological progress in most hospitals, which is their significance and the brilliance of human beings developing tools.

It solves a problem at its root, giving people a sense of security and confidence.

Wu Xuanqi approached Nie Mingxian and asked softly, "Are you really leaving Han City? Can't you stay?"

"Is it because you're unhappy?"

Wu Xuanqi knew something about Nie Mingxian and Liu Guo, but he didn't reveal it.

Don't meddle in the relationships between brothers and friends.

You say a few words to him, it only takes a few minutes, but it affects someone's entire life.

Only your own feet know whether the shoes fit or not.

Nie Mingxian shook his head slightly: "What else could I be unhappy about?" "I'm definitely leaving, after all, I'm still studying." Nie Mingxian said.

Wu Xuanqi cannot deny this point either.

Nie Mingxian is currently pursuing a doctorate, and he will definitely get his diploma and degree certificate.

Otherwise, Nie Mingxian's many trips would have been purely for thrills.

After thinking for a while, Wu Xuanqi cautiously said, "Should I find one for you in the advanced group?"

"She must be virtuous and talented, and beautiful and intelligent."

Upon hearing this, Fang Ziye, who was taking pictures, twitched his ears slightly: "Brother Qi, what group are you talking about? Can I join?"

Fang Ziye had always been curious about what a group was.

I just never had the chance to go in.

Of course, Wu Xuanqi also told him about this group.

It turns out there's such a high-end kind of 'matchmaking group'.

Upon seeing Fang Ziye, Wu Xuanqi immediately shook his head: "You can't come in. If you do, I'm afraid you'll just wipe out this group chat."

If Fang Ziye had no connection with Luo Tingzhu, and if Fang Ziye's network of connections were even slightly narrower, Wu Xuanqi would probably have brought Fang Ziye into the picture.

Because of Luo Tingzhu, Wu Xuanqi was genuinely afraid that Fang Ziye would completely destroy the group chat.

You know, Fang Ziye might now be chatting with someone in the department whose name and gender are coded, and complaining bitterly.

I guarantee this group will disappear before long!
Upon hearing this, Fang Ziye's attitude shifted to one of victory: "Brother Qi, what if I said I absolutely have to go in?"

Lan Tianluo, that bastard, managed to seduce even a professor in the Department of Respiratory Medicine. Fang Ziye was also very curious about how this group operated.

Why does Lan Tianluo harbor such resentment?

Of course, if necessary, it's Lan Tianluo's business to vent his anger, and Fang Ziye wouldn't mind kicking him while he's down.

Fang Ziye's formal and aloof tone made Nie Mingxian sit up straight.

Staring blankly at Fang Ziye, he uttered, "Is the dragon-slaying youth about to grow into a vicious dragon?"

Fang Ziye is usually a very easy-going person, always cheerful and polite, and never loses his temper.

But today, Fang Ziye's tone was completely unlike his usual self.

Wu Xuanqi said almost without hesitation, "Then I'll recommend you to join. I'll tell the group admin about your identity first, and you'll definitely be able to get in."

Wu Xuanqi didn't argue with Fang Ziye at all and immediately agreed to Fang Ziye's request.

After asking the group owner for his opinion, Wu Xuanqi even showed Fang Ziye some of the previous group announcements.

The first sentence states that the purpose of this group is to provide high-quality matchmaking partners and basic information, and all forms and means of coercion are prohibited.

Secondly, this group...

"Brother Qi, there's no real point in looking at this. I just joined the group to lurk for a while." Fang Ziye didn't care about this.

What he wants to understand is how the group operates, not the group announcements.

Furthermore, Fang Ziye was even more curious about what exactly this group was doing.

Of course, Fang Ziye wasn't afraid that Wu Xuanqi would tell the group owner, since he was just curious and didn't really want to know anything.

"What are you doing?"

"Ziye, don't you have a girlfriend? Aren't you afraid of being misunderstood for joining this group?" Nie Mingxian asked curiously.

"It's alright. If Tingzhu knew I was in this group, she would be very curious too," Fang Ziye said nonchalantly.

"Well, this industry is really messy." Nie Mingxian still didn't know the specifics of what had happened.

But he couldn't be bothered to care.

However, after glancing at the rather listless rabbit, Nie Mingxian said, "Why don't we help it set its leg?"

"More than 30 hours have passed, and the lower limbs are still active."

"If you're taking a plane, it takes about the same amount of time to get from China to the United States."

Wu Xuanqi skipped over the topic with Fang Ziye and asked, "Don't you want to know the time limit all at once?"

"I'm not really curious."

Nie Mingxian suddenly said, "Hey, do you all know about the conflict between Liu Guo and me?"

Nie Mingxian spoke casually, as if he were talking about whether the two of them wanted to drink water.

Wu Xuanqi and Fang Ziye both nodded.

"Alright then! This is Zhongnan Hospital, this is Wuhan, this is your home turf, and you have many eyes and ears here."

"However, you certainly can't monitor whether Liu Guo and I go out to eat, right?"

"Actually, let me tell you, it's still hard to say who will turn whom!" Nie Mingxian said, gritting his teeth.

Clearly, they have a very low opinion of the person behind Liu Guo.

Hearing this, Wu Xuanqi cautiously said, "Brother Xian, if Liu Guo has really been swayed by her director, then this kind of woman isn't worth your investment!"

Feelings are not a transaction. If Liu Guo had listened to the director and made similar requests to Nie Mingxian, then this person would no longer need to be the sister-in-law.

This is Nie Mingxian's most fundamental idea.

Go to hell! I'm going to stay at Zhongnan Hospital, and I'm going to work in the vascular surgery department before you'll even start dating me. Are you an idiot?
"Don't judge a book by its cover!"

"Who among you could have imagined that Professor Qian Zhong, the head of the general surgery department, is Liu Guo's biological father?"

"The reason why one of them has the surname Qian and the other has the surname Liu is that when Liu Guo was born, her health was too poor, so they followed the old man's idea and said that she should be adopted by someone else so that she could be raised properly."

"So Liu Guo took a godfather, who was Professor Qian's good friend, and got the name Liu Guo," Nie Mingxian said casually.

"What I'm hesitating about now is whether or not I should 'sell myself'."

Nie Mingxian said calmly.

Wu Xuanqi and Fang Ziye were both taken aback by Nie Mingxian's words.

After a few seconds, Wu Xuanqi exclaimed, "Oh, so this Liu Guo is actually a second-generation super-rich kid from Zhongnan University?"

“Well, personally, I don’t think it’s too much for her father to say that to her, right?” Nie Mingxian grinned from ear to ear.

Indeed, if the identity were reversed, this request wouldn't seem so unreasonable.
