But in this hospital, there are many new drugs that have been listed abroad but not in China, and they are being studied. If the conditions are right, you can join the group, so you don't need any money, but you can enjoy new drugs or at least routine treatment by joining the control group. Depends on what you think. Some people think that this is doing research on themselves, but international organizations say that this is a positive treatment method, encouraging patients to actively participate, so that patients can enjoy international advanced treatment concepts and drugs. Maybe this concept is not so popular in China.
If you want to know more about these studies, you can go to the hospital's internal medicine professor. They have a lot of research and rich experience in this field.
I hope I can help you. Your filial piety is very touching! Remember to help my mother treat:)
