4. Pregnant or lactating women.
5. Other clinical trials of drugs were used in the first four weeks before the first dose.
6. The subjects had any history of autoimmune disease or any use of systemic glucocorticoid or immunosuppressive medications.
7. Hereditary or acquired bleeding and thrombotic tendencies (such as hemophilia, coagulation dysfunction, thrombocytopenia, hypersplenism, etc.).
8. Congenital or acquired immune deficiency (such as HIV infection);
9. Receive live vaccine within 4 weeks before or during the study period;
10. Patients who are allergic to or contraindicated to the experimental drugs.

Primary Outcome Measures

Name	Time	Method
Progression Free Survival，PFS	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 10 months	The time from the date of randomization to the date of first documented progression or date of death from any cause, whichever came first.

Secondary Outcome Measures

Name	Time	Method
Number of participants with Adverse Events	From date of treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 10 months	Adverse Events are monitored throughout the trial and for 30 days after discontinuation of treatment (90 days for serious adverse events) and graded according to the Common Terminology Criteria for Adverse Events, version 4.0, of the National Cancer Institute.
the correlation between the expression of PD-L1 of circulating tumor cells and prognosis	From one week before treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 10 months	To detect the differences of the expression of PD-L1 in patients with different curative effects and prognosis,including the number of circulating tumor cells,and PD-L1 expression or others.
