On the second day after the operation, Brian's drainage tube and urinary catheter were removed, and he began to get out of bed with his waistline. He was very satisfied with the results of the operation.
Some researchers in the laboratory often come over to chat with Brian when they have time. Of course, the topic of these people's chats is still academic. Anyway, just a few casual conversations can get into the academic topic. Especially Lu Xiaolu is a rare genius and has a lot of understanding.
Far more than the average person, after many communications with a master like Brian who is at the forefront of academic circles, I have benefited a lot and many problems have been solved easily.
In terms of tumor research, Yang Ping's current idea is to use M13 phage as a carrier to carry K factor that can kill tumor cells into the human body, and then carry out selective affinity to tumor cells, thereby killing tumor cells. This kind of
The idea is very good, but the actual implementation is very difficult.
Among them, embedding the K factor into the M13 phage is a difficult problem, and secondly, making this complex have selective affinity for tumor cells is another problem.
System space can only provide time, space and materials, but cannot provide ideas for solving problems, so Yang Ping has to think about how to solve the problem himself. Yang Ping put forward the idea, but now many specific technologies are needed to realize this idea.
In terms of immunology, especially research on tumor immunology, Brian can be said to be the most advanced in the world, and some of his specific experimental methods can be used for reference.
A sea that is open to all rivers is tolerant, and this is the attitude towards academics.
Brian's post-operative MRI photos are hung on the electronic reading screen. Although the metal implants interfere with the image to a certain extent, the details of the surgical area can still be seen clearly. The huge prolapsed intervertebral disc nucleus pulposus has been removed, and the nerve compression
Naturally, the spondylolisthesis has been reduced, and the lumbar 4 and 5 vertebrae are firmly fixed by pedicle screws. In the future, the lumbar 4 and 5 vertebrae will fuse together, and the two fractures will become one bone. This segment
In this way, long-lasting stability is achieved. Of course, you also lose your mobility at this stage, but there are five lumbar vertebrae. Losing the mobility of one segment has little impact on the mobility of the entire lumbar spine. It has almost no impact on the elderly.
, but it still has an impact on young people, who have higher requirements for waist activities.
"Professor, if there is no lumbar instability and it is just a simple lumbar intervertebral herniation, would you also choose a combination of disc removal, intervertebral bone grafting and fusion, and pedicle screw internal fixation?"
"Yes, many young and middle-aged people nowadays only have lumbar disc herniation. Can they just perform disc removal?"
The students surrounding him expressed their doubts.
"If the patient is a young or middle-aged patient and there is no lumbar segmental instability, then this combination of surgery should not be chosen and only lumbar disc removal should be performed. Now a large number of samples show that the effect of lumbar disc removal alone is very good."
Yang Ping explained it to everyone.
Brian was wearing a waistband and a walker next to him. In fact, he could walk on his own. He just asked his escort to follow him with the walker. If he got tired, he could use the armrests of the walker to rest for a while.
Brian didn't know how to read MRI films, but Maninstein had shown him several times, and he understood a little bit. He couldn't tell anything else, but he could understand at least two things. One was the huge nucleus pulposus in the MRI films.
There was a black thing on the top, but it has disappeared now. Secondly, the front and back edges of the two vertebrae were originally staggered, but now they are on a line. It is obvious that they have returned to the correct position.
Brian's curiosity made Brian think a little wildly. In fact, the interlacing of lines is more prominent in English-speaking countries than in China. In the Chinese-speaking world, as long as you know the characters, you can understand a little bit of other professional books, at most some professional terms.
I don’t understand the meaning, but I can still understand the basic content of the expression.
But in the English-speaking world, as long as you jump to a major that you have no contact with at all, even a professor as big as Brian will not understand anything. This kind of incomprehension is really incomprehensible, not at all, all you see is
letter.
This is like beef, dog meat, and pork. In Chinese, even if you know it, at least you know it is meat or animal meat. In the English-speaking world, what is this thing is completely blank. Therefore, many senior intellectuals in the English-speaking world do not know
How do you say cuboid? It’s not surprising that you don’t know what it is when you see the word cuboid.
"If I bend down, will this metal screw break inside my body?" Brian was worried about this.
Yang Ping told him: "It is possible, but it may be slim."
"What if the fault is inside?" Academic people like to get to the bottom of things.
"The duty of these metal fixations is temporary fixation, that is, before the two vertebrae grow together, the stress is shared by the metal internal fixation. Once the vertebrae grow together, its duty has been completed. Therefore, this problem is divided into two
Judging from this situation, if the screws break after the vertebrae are fused, the screws can be taken out. If the vertebrae have not been fused, the only option is to have another surgery to replace the broken internal fixation with a new internal fixation and re-fix it.
"Yang Ping satisfied his curiosity.
"If the screw is broken inside the vertebrae, as if it is buried inside, how do you remove it?"
It seems that Brian has studied this issue as a serious academic issue.
It is also a good way to let everyone see how a Nobel Prize winner thinks about problems, and at the same time let everyone know that no professor is an authority. They are all human beings and must have their own cognitive limitations. There is no authority in the eyes of real scientific researchers.
, you must have a sense of questioning and the ability to question.
Yang Ping pointed at the internal fixation on the screen with the pencil's eraser end: "If it's broken inside the vertebrae, there's no need to remove it at all, just leave it in. But if you want to take it out, it's not impossible, it's just a little troublesome. It's okay.
This is necessary.”
"If metal stays in the body for a long time, will the released metal ions enter the blood? Then spread around in the human body? Will it not affect physical health?"
The more Brian asked, the more curious he became, and he was already immersed in this kind of thinking.
Yang Ping told him slowly: "The question you asked is very meaningful. This is also the biggest potential risk of metal-on-metal artificial hip joints at present. A large amount of metal ions enter the human blood, which has unknown potential risks, such as causing cancer. But
This exists in metal-to-metal artificial hip joints, because the friction between metal and metal will cause a large amount of metal debris to fall off, and a large amount of metal ions to enter the blood. However, the broken screws in the vertebrae just mentioned do not exist as you are worried about, because
The metal left in the vertebrae has no friction and is surrounded by bone. It can be considered as an inactive piece of metal. There is no large amount of metal ions entering the blood, so it can remain in the body for life. "
Brian was thoughtful, as if he didn't understand.
These are common sense to a spine surgeon, but to Brian, he felt they were a major discovery.
This is not surprising, because this knowledge is in his blind spot. No matter how he thinks, he lacks corresponding thinking content. Without strong content to support, his thinking will appear pale and feeble.
"Will it rust? Or will it react chemically with ions in the surrounding bone tissue? If a chemical reaction occurs, can it be controlled?"
Brian touched his chin and raised this question seriously.
