Han Kongque said: "Everyone knows that various parts of sharks can treat cancer, and it is quite controversial. What is there to promote? Is it possible to be famous for this?"
"It's just that he is famous. The anti-cancer substances extracted by others are not as effective as those extracted here. The father of the young man you are optimistic about has achieved very good results after our treatment for a period of time.
If we can continue to suppress the division of cancer cells, although there is not much certainty of a complete cure, there is no problem at all in maintaining the current state and allowing the human body to age naturally." Liu Xu said happily.
Han Kongque said: "The effect is so good?"
Liuxu rolled her eyes at him and said: "The ones you raise are more effective. The ones caught from the ocean can only be decided by chance. Some are effective and some are not. You can't say that. It can only be said that they are effective."
The shark extract has no effect on one patient, but has an effect on another patient. We are stepping up research on this aspect, and this may be related to both the shark itself and the patient's physical fitness."
Han Kongque said thoughtfully: "Every shark is a unique individual, and even if patients have the same disease, the viruses they carry are not necessarily the same. This definitely needs to be studied carefully."
Liu Xu smiled bitterly and said: "Actually, it doesn't have much research value. Just like if liver tumor cells can be transmitted, when they are introduced into another person's body, after combining with that person's liver cells, some mutations will occur and the cells will become different from the original ones.
The tumor cells are completely different, so the pathogens of each patient are different, so such research is really unnecessary."
"Doesn't this mean that every patient needs different medicines to treat?" Han Kongque said.
Liu Xu said: "In principle, it is like this, but there are many drugs that can inhibit most tumor cells. This is the kind of drug we need to look for."
"Nothing can be perfect. It is impossible for us to mass-produce panaceas like those in ancient legends that can cure hundreds of poisons. However, it should still be possible to target several types of tumor cells.
.
Just like the liver tumor cells you just mentioned, as well as head and neck cancer, these should be able to be conquered. This was done as early as the early 20th century, but there was no large-scale clinical application." Han Kongque said.
Liu Xu frowned and said: "I'm a professional medical student, but I don't know about this news? You, a monk halfway, know more than me?"
Han Kongque said: "Wait for me to collect some information and send it to your mailbox. You can take a look when you have nothing to do. Also, has the virus laboratory I asked you to set up earlier established? The collection and cultivation of various viruses are all
If you do it well, there may be a good medicine to cure the disease."
"This is very simple. It just collects and cultivates viruses. As long as you take good protection. It's not difficult. Even ordinary undergraduates can do this very well. I have already asked people to organize it, but it has just been established, and the virus samples collected are still too small.
There are few, and most of them are snake venom. The old snake is responsible for this." Liu Xu said.
Han Kongque said: "You also need to set up a laboratory, which is a drug missile laboratory. Do you know what a drug missile is?"
Liu Xu said: "You are talking about targeted drug delivery, right?"
"So, the purpose of both is exactly the same. That is to deliver the drug directly to the lesion where the drug is needed and directly act on the lesion, while the drug missile will be more precise.
You also know that there are many drugs, although they can have a good effect on some diseases, but after they are delivered into the patient's body, these drugs will enter the blood circulation, and in the process, they will flow through various body tissues, maybe
By the time they reach the lesion, these drugs have already been absorbed and digested by other body tissues.
By this time, the effect of the drug is almost gone, or the therapeutic effect is weakened. Drug missiles, on the other hand, deliver the drug directly to where it is needed, which is the kind of targeted drug delivery you mentioned.
But targeted drug delivery is too difficult, and most people can’t do it, so we can only find ways to make the drug into a missile, which will only detonate when it reaches the target area, so the effect will be better.”
"The drug missile you mentioned is not simple at all!" Liu Xu said.
Han Kongque said: "It's not difficult if you don't know how to do it. As long as you find the right method, it's not difficult." Han Kongque said.
Han Kongque said with a smile: "Drug missiles targeting liver tumor cells have actually been achieved in the 1990s. If we study it ourselves, we may be able to make it."
"Show me the relevant information. I really haven't heard of this." Liu Xu said.
Han Kongque said: "Our domestic medical education is too formal. Many cutting-edge and exploratory things are not studied by anyone. Just like drug missiles, which is what you call targeted drug delivery, I don't know if there are any."
People are studying it, but it is indeed a good way to cure diseases. Regardless of whether others study it or not, we must study it.
To give the simplest example, many drugs can fight cancer. Why can't they achieve the results in the laboratory in clinical practice?
That's because the drug cannot directly reach the lesion and cannot directly act on the lesion. This is the purpose of our research. Our research is not to make reports or publish papers, but to treat people."
"Well said, in this case, do you want to show off your skills? We have a patient with mid-stage gastric cancer here. Although the tumor was removed, the later treatment effect was not satisfactory." Liu Xu said.
Han Kongque frowned and said: "Gastric cancer should be the easiest to administer. Don't the anti-cancer drugs we extracted work?"
"It works. It is definitely better than the standard treatment methods in ordinary hospitals, but the effect is still not satisfactory." Liu Xu said.
Han Kongque said: "What consequences do you want? A complete cure?"
"Of course, cancer cells are highly reproducible and we cannot be careless at any time. If we are not careful, they will relapse. Therefore, being able to completely eliminate cancer cells is what we should do." Liu Xu said matter-of-factly.
Han Kongque said funnyly: "So you also had this idea when you were a surgeon?"
Liu Xu's expression froze: "I was just an ordinary doctor at that time. What's the use of thinking so much? Don't they all say? The butt determines the head. Although this saying is a bit crude, the truth is still right. Now I am a hospital doctor.
Sir, there are cancer patients in our hospital, can’t we think of curing them completely?”
Han Kongque directly hit her confidence: "Don't talk about us, there are many well-known research institutes in the world who want to do it, but cancer cells are ever-changing, and the drugs that are very effective in this patient are not available in another patient."
A little effect, this kind of thing happens all the time, so wake up! We can only do our best and obey fate."
"Your idea is not good. A soldier who doesn't want to be a general is not a good soldier. If you don't want to completely cure the disease, what's the point of being a doctor?" Liu Xu objected.
Han Kongque: "Let's go and see the patient. He should be Shang Xiaoyang's father, right?"
"Yes, it's the father of the student you admire very much. They trust us very much, so they sent his father to our hospital. This is the first cancer patient our hospital has officially accepted." Liu Xu turned around and led Han Peacock.
Go to a ward.
Han Kongque and Liuxu walked in, where there were several people sleeping with them.
"Hello, Dean Liu." Several people all stood up and greeted Liu Xu warmly.
Liu Xu nodded and said to the man on the bed who thought his face was dark: "How is it? Do you feel anything special?"
"It's okay, I feel very good. I even had a bowl of porridge today." The patient spoke with a strong voice, giving no indication that he had just undergone surgery a few days ago.
Han Kongque released his spiritual consciousness and sensed the patient's stomach. He found that the stomach tumor had disappeared and the surface of the incision had begun to heal. At this time, he could start eating liquid food.
Cancer cells cannot be sensed by Han Kongque, so he can only see his cases and some pictures taken.
"The mass has been removed, but the cancer cells cannot be completely removed. In the mid-term, they are already on the verge of spreading. Now, our drugs can only inhibit the spread of cancer cells and prevent them from causing greater harm to the patient." Liu Xu said.
Han Peacock said.
Han Kongque said: "So the cancer cells are still growing?"
"Drugs can only inhibit or destroy the rapid division and reproduction of cancer cells, but they cannot completely eradicate them. Therefore, cancer cells will continue to grow." Liu Xu confirmed, and Shang Xiaoyang's family members all fell silent, and they listened carefully.
.
Han Kongque saw that they didn't have much worry, thinking that Liuxu had already told them these things.
Han Kongque said: "Can it be combined with chemotherapy to further treat cancer cells?"
Liu Xu shook his head directly and said: "The effect is not very good. If chemotherapy is carried out, it will not reach the current level at most. In that case, it may destroy the patient's intact tissue and cause the patient's immunity to further decrease. Therefore, if there is no better
The best way is to maintain it like this."
"Maintain it like this?" Han Kongque shook his head. This kind of cancer treatment drug is not affordable for ordinary people. If you rely on this kind of drug to maintain it, the cost will be very high in the future.
Liu Xu said helplessly: "With this kind of medication, after the patient recovers from the incision, as long as he doesn't forget to take the medicine, he will work and live like a normal person. If he doesn't take the medicine, the cancer cells will reappear in at least half a year and at most five years."
It has developed to the extent that it was opened before.
At this time, surgical resection will be performed again. At that time, the spread of cancer cells will inevitably occur. Of course, this requires frequent inspections. The growth rate of cancer cells is very fast. As long as it is a little later, there will be
