Patients who received the live attenuated vaccine within 4 weeks before the first dose of study treatment. Note: Inactivated virus vaccines for injectable seasonal influenza are permitted for up to 4 weeks prior to initial administration; But live attenuated influenza vaccines are not allowed; Patients who received major surgery within 4 weeks before the first dose of study treatment(open chest, craniotomy or laparotomy) or expected during the research and treatment need to accept major surgery not associated with this study.

Patinets with deep vein thrombosis, pulmonary embolism, or any other serious history of thromboembolism within 3 months (implantable venous infusion port source sex or catheter thrombosis, or superficial venous thrombosis were not regarded as a "severe" thromboembolism).
