Long-term unhealed wounds or incomplete fractures
A previous history of organ transplantation
Imaging shows that the tumor has invaded important blood vessels or the researcher has judged that the patient's tumor is highly likely to invade important blood vessels to induce fatal bleeding during treatment

Those who have a history of psychotropic drug abuse and can't be prevented or have mental disorders
Have a history of immunodeficiency, or have a history of organ transplantation
According to the judgment of the investigator, there are accompanying diseases that seriously endanger the safety of the patient or affect the completion of the study
Have a history of surgery within 28 days
