Subject has previous or concurrent other malignant tumors (except for cured basal cell carcinoma of the skin and carcinoma in situ of the cervix); 19. Known subject has been allergic to macromolecular protein preparations in the past, or known to be allergic to the drug components applied; 20. Subject has any active autoimmune disease or has a history of autoimmune disease (such as the following, but not limited to: autoimmune hepatitis, interstitial pneumonia, uveitis, enteritis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism, and those who have undergone thyroid surgery in the past cannot be included; Subjects with vitiligo or who have had complete remission of asthma in childhood and do not need any intervention after adulthood may be included; Asthma in participants requiring medical intervention with bronchodilators could not be included); 21. Subjects are using immunosuppressants, or systemic or absorbable topical hormone therapy to achieve immunosuppressive purposes (dose> 10mg/day prednisone or other efficacy hormones), and continue to use them within 2 weeks before enrollment; 22. Clinically symptomatic ascites or pleural effusion requiring therapeutic puncture or drainage; 23. Patients with uncontrolled cardiac clinical symptoms or diseases that are not well controlled, such as: (1) NYHA level 2 or above heart failure (2) unstable angina pectoris, (3) myocardial infarction within 1 year, (4) clinically significant supraventricular or ventricular arrhythmia requiring treatment or intervention; 24. Subject has active infection or fever of unknown cause > 38.5 degrees during the screening period and before the first dose (as judged by the investigator, the subject can be enrolled due to the fever caused by the tumor); 25. Patients with a history of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonia, severe impairment of lung function, etc. 26. Subject with congenital or acquired immunodeficiency, such as HIV infection, or active hepatitis (aminotransferases do not meet the inclusion criteria, hepatitis B reference: HBV DNA= 1000 IU/ml; Hepatitis C reference: HCV RNA =1000 IU/ml); Chronic hepatitis B virus carriers, HBV DNA < 2000 IU/ml, must receive antiviral therapy at the same time during the trial to be enrolled; 27. Live vaccine received less than 4 weeks before the study administration or possibly during the study period; 28. Subject has a known history of psychotropic substance abuse, alcoholism, or drug abuse; 29.
