cerebral ischemia or cerebral hemorrhage diseases;
6. The investigator determines that there are serious complications or diseases that
increase the risk of the subject or affect the study, including but not limited to,
for example, cirrhosis of the liver, recent major trauma, etc.;
7. Allogeneic hematopoietic stem cell transplantation performed within six months prior
to screening, or hematopoietic stem cell transplantation performed during the
screening period for any immunosuppressive treatment due to graft-versus-host disease;
