- Received treatment with live vaccines within 28 days before the first administration; except for inactivated viral vaccines for seasonal influenza;
- Patients who need to receive systemic corticosteroids (\> 10 mg/day curative dose of prednisone) or other immunosuppressive drugs within 14 days before the first medication or during the study period.

- The patient is a female during pregnancy or lactation;
- The patient has other diseases or abnormal mental states, which may affect the patient's participation in this study;
- There are patients who may increase the risk of participating in research and research medication, or other severe, acute and chronic diseases, who are not suitable for clinical research based on the judgment of the investigator.
