After the lecture, Yang Ping returned to the office and used his computer to answer questions from forum members online.
One hour of Q&A time, very relaxing.
The Chinese proficiency of these people is improving every day.
In fact, it’s not how difficult it is to learn Chinese, but how motivated you are to learn.
When the motivation is strong enough, difficulty is no longer a problem.
At this time, August is indeed at a disadvantage. For the sake of fairness, Yang Ping plans to move the lecture time to around 6 p.m.
For me, it is also a good thing to have dinner early in the afternoon and then get together to lecture and study for two hours.
This way everyone has a balance in time, and August doesn’t have to stay up all night.
It’s just a lecture, there is no need for people to risk sudden death.
Zhang Lin has received three applications for further study. August and Robert are for three months of further study, while Takahashi is for two weeks of short-term study.
August and Robert will come to China a week later.
Takahashi will come to China two days later.
Takahashi applied for further study a full month earlier than Robert.
The strange thing is that Takahashi didn’t mention a word about further training in the forum chat room.
Because, he also has an important task, which is to secure a base for the Phase III clinical trial of spinal external fixator for Dongda Hospital.
He understood that this opportunity only laid the foundation for other subsequent cooperation, so he must take it.
Takahashi has also inquired from many parties and pondered over and over again. If he can win the experimental cooperation on spinal external fixation, it is very likely that there will be many cutting-edge technology cooperation in the future.
Therefore, if you arrive one step earlier than the Americans and Germans, you will have a greater chance.

The results of Li Jun's preoperative examination came out. Because of uremia, the biochemical results must be messy, especially the creatinine was ridiculously high.
Li Guodong arranged for him to undergo dialysis in the hemodialysis room, and dialysis was done twice a week regularly.
The nephrologist consulted and said that twice a week might not be enough, so we need to increase the frequency to three times a week.
Because of renal anemia, Li Jun’s face is not very good-looking.
The originally fair face lost a bit of life.
But in any case, this disease can be treated, and if a kidney can be successfully transplanted, one can live a normal life.
Li Jun is quite lucky. If he had been waiting for a kidney source like others, he didn't know how long he would have to wait. Fortunately, his boyfriend Qin Xiaowei's kidney was a good match for him.
However, regardless of whether it is a relative or non-relative, kidney donation must undergo ethical review.
The main concern is that this kind of donation may be adulterated with organ trading.
Donors for organ transplants have always been very tight, especially because there are very few donated organs in China. Therefore, for a long time, the only way to get a quick kidney transplant was through sideways.
Sunshine Boy Qin Xiaowei is still wearing the same T-shirt, and the weird tattoos on his arms are very eye-catching. One look at the outfit reminds people of those fashionable guys who dance hip-hop.
With a pocket bag wrapped around his waist, he secretly came to Yang Ping's office and gave Yang Ping a medium-sized red envelope.
Yang Ping rejected him.
The young man said sincerely that he wanted Yang Ping to perform the surgery. He knew that this operation was very risky and he did not want Ajun to have any sequelae. Ajun was already suffering enough.
Yang Ping reassured him that he would do his best.
Uremia is not a contraindication to surgery. After dialysis, surgery can be performed the next day, which does not have much impact on the safety of anesthesia and surgery.
You just have to be more careful when calculating drugs for anesthesia.

The first day after hemodialysis is the period when uremia patients are in their best physiological state, and Li Jun’s surgery began.
Supine position, routine disinfection and draping.
Yang Ping's scalpel made a vertical incision in the middle of the lower abdomen.
Pelvic tumors involve the sacrum, especially tumors in the sacral canal. This is a professional category of bone tumors, and there are many nerves and blood vessels around the sacrum, making surgery very difficult.
In most cases, this kind of surgery requires the cooperation of bone tumors, general surgery, and urology surgery.
This is also the result of the professional subdivision of modern medicine. General surgeons are familiar with the liver, gallbladder, pancreas, spleen and gastrointestinal tract, and are helpless when it comes to the kidneys, bladder and ureters; while urologists are just the opposite; both general surgeons and urologists, once
It went deep around the sacrum, so I never dared to do anything, let alone open the sacral canal.
There are specialties in the surgery, so once the surgery is beyond the scope, they will naturally not do it, and they do not have the corresponding anatomy knowledge.
Of course, some bone tumor doctors with relatively skilled anatomy knowledge can handle this type of tumors independently without the need for cooperation with general surgery and urology surgery.
For Yang Ping, his knowledge of anatomy has reached a level of proficiency, so there is no need for cooperation from other departments.
In terms of surgical authority, Sanbo Hospital had already relaxed his restrictions.
The scalpel is sharp and can cut through the skin, subcutaneous tissue, fascia and muscles, and open the peritoneum.
Yang Ping pushed open the intestines and various organs, revealing part of the tumor, and the encapsulated flesh ball appeared in everyone's field of vision.
The surface of the capsule is dotted with blue and red blood vessels, some of which are dilated.
"I heard that Nezha's mother gave birth to a meat ball after three years and six months of pregnancy. Do you think it was also a teratoma at that time?"
Zhang Lin asked while pulling the hook.
"Since it is a teratoma, why did I cut out a lively little human with one knife? Is this considered a medical malpractice? Misdiagnosis!"
Xiaowu continued.
Every time these two brothers perform an operation, in addition to retracting the hook, they also have an important mission, which is to enliven the atmosphere.
Song Zimo doesn't like to talk, and Xu Zhiliang's talk makes people anxious, except for rescue.
Yang Ping's vascular forceps used blunt dissection to separate the surrounding tissue bit by bit. This tumor has quite a lot of blood vessels and is inextricably linked to the presacral vascular plexus.
A large piece of gauze is placed around the tumor to separate the tumor from the surrounding tissue and prevent tumor cells from falling off and planting.
No one dares to say whether a tumor is benign or malignant until its nature is determined.
Therefore, in any tumor surgery, try to achieve tumor-free techniques---this is the basic technology of tumor surgery.
It is both an operating technique and an operating principle.
That is, during the entire operation, try not to let tumor cells come into contact with other normal tissues to prevent the cells from falling off and taking root like seeds.
"Is it moving?"
While chatting, Zhang Lin saw the meat ball jumping and moving.
"Professor, he is pulsing. Is this the fetal heartbeat?"
Yang Ping did not speak. After completing the gauze isolation work, he said: "You guys have a feel for what it is."
Zhang Lin put his palm on the surface of the sarcoma. This was not a sarcoma. It was clearly beating like a fetal heart. He had just become a father and felt it even more clearly.
This beating is very rhythmic, it is the beating of the heart.
How can a tumor have the beating of a heart?
Zhang Lin's eyes were full of surprise, and his voice was a little loud: "Fetal heartbeat?"
Moreover, he concluded that Yang Ping just asked him to feel it with his own hands just to test him. If he hadn't made any new discoveries, how could he be tested?
The instrument nurse, circulating nurse, anesthetist and all the idle staff in the audience suddenly froze, and the operating room fell silent.
In the open surgical area, the tumor beat with a very strong rhythm.
As Zhang Lin said, only the fetal heart beat can be so rhythmic.
Song Zimo and Xu Zhiliang did not speak at the side, because the two brothers were touching the tumor, and Song Zimo and Xu Zhiliang had no chance to make contact for the time being.
Yes, the fetal heart rate is absolutely correct.
Zhang Lin once felt this kind of pulsation through his wife's belly.
"Professor, it's the fetal heartbeat!"
Zhang Lin is very sure.
This time, he will be able to establish a glorious image of himself in front of the students. Neither Song Zimo nor Xu Zhiliang noticed it, which is not surprising because they have not yet become fathers.
Man!
Is it really possible to get pregnant?
Think of that ridge vertebra, this is a fetus.
It’s so magical.
Umbilical cord? There is an umbilical cord, professor!
Zhang Lin's hand touched something like an umbilical cord, and Xiao Wu also confirmed it at this time.
It’s really the umbilical cord.
Surgeons have experience in obstetrics and gynecology, so they know what the umbilical cord looks like.
This feel, this thickness, this texture, it’s really an umbilical cord!
The fetal heart beats. If you are careful, you can hear the beating sound of the little heart.
Fetal heartbeat, umbilical cord, what is it if not the fetus?
The two brothers exchanged heated glances and then nodded: This is the fetus!
Is this an intersex person really pregnant?
People around him cast doubtful glances at Yang Ping, hoping that the professor could give them answers.
The young professor was very steady. He slowly changed a pair of gloves and said kindly: "This is the feeding blood vessel of the tumor. Which thicker artery does not pulse in a living body? You can feel his aorta, or the internal and external iliac
Arteries?"
Zhang Lin and Xiao Wu looked at each other and put their hands in. Really, the aorta was pulsing, as were the internal iliac arteries and the external iliac arteries.
How could I forget this!
The glorious image he had just established collapsed in an instant, and Song Zimo spoke at this moment: "The professor asked you to touch it to let you feel the texture of the teratoma, not to judge whether it is a fetus."
"Oh---"
Zhang Lin and Xiao Wu stopped talking and focused on pulling the hook.
After all, pulling the hook is the two brothers' whole job.
Be a hooker honestly and don’t think about establishing a tall and glorious image in front of students all day long.
