* male subjects are willing to keep abstinence or take medically approved high-efficiency contraceptive measures from the time of signing the informed consent to 6 months after the end of the last medication, and do not donate sperm during this period. * all subjects are required to provide tumor tissue specimens that can be used for target analysis, which must be archived specimens or fresh biopsy specimens (bone biopsy specimens are not accepted). only those with positive target expression can enter the study. 2. exclusion criteria: * history of severe allergic diseases, severe drug allergy (including unmarketed test drugs), or known allergy to any component of the recommended drugs (including pretreatment drugs) in this program; * those who have received coronary artery reconstruction in the past; * evidence of significant bleeding disorders or other significant bleeding risk: * history of intracranial hemorrhage or intraspinal hemorrhage; * tumor lesions invade large blood vessels and have obvious bleeding risk; * thrombosis or embolism occurred within 6 months before cell reinfusion; * clinically significant hemoptysis or tumor hemorrhage occurred within 1 month before cell reinfusion; * anticoagulant therapy for therapeutic purposes (except low molecular weight heparin) has been used within 2 weeks before cell reinfusion; * antiplatelet drugs, such as aspirin (\>325 mg/day), clopidogrel (\>75 mg/day), dipyridamole, ticlopidine or cilostazine, were used within 10 days before cell reinfusion azoles, etc.; * received the following treatments or drugs before cell reinfusion: * unhealed wounds, ulcers or fractures within 28 days before cell reinfusion; * inoculated with live attenuated vaccine within 28 days before cell reinfusion; * received nitrosourea or mitomycin c treatment within 6 weeks before cell infusion; received oral fluorouracil treatment 2 weeks before cell infusion or within ●half-lives of the drug (whichever is longer) ; * received corticosteroids within 2 weeks before cell reinfusion, or it is expected that corticosteroid treatment may be required during blood collection, cell collection or cell reinfusion; except for the following cases: short time (≤7 days), dose not higher than 10 mg/d prednisone or equivalent dose of corticosteroids for the prevention or treatment of non-autoimmune conditions; topical, intranasal, intraocular, intraarticular or inhaled corticosteroids; * known leptomeningeal metastases, or uncontrolled or symptomatic central nervous system metastases manifested by clinical symptoms, cerebral edema, spinal cord compression, and/or progressive growth. subjects with a history of central nervous system metastasis or spinal cord compression are acceptable if they have clearly received treatment and are clinically stable after 8 weeks of discontinuation of anticonvulsants and steroids before cell reinfusion; * the existence of any form of primary immunodeficiency; * there is any active autoimmune disease, or there is a history of autoimmune disease and relapse is expected (including but not limited to: systemic lupus erythematosus, rheumatoid arthritis, psoriasis, multiple sclerosis, inflammatory bowel disease, need for bronchial asthma subjects medically intervened with dilators, except for the following: type 1 diabetes; skin conditions not requiring systemic therapy \[eg, vitiligo, psoriasis, alopecia\]; hypothyroidism only receiving hormone replacement therapy; childhood asthma in complete remission without any intervention in adulthood; or others not expected to relapse in the absence of external triggers); * within 6 months before cell reinfusion, the following conditions have occurred: myocardial infarction, severe/unstable angina, clinically significant arrhythmia requiring clinical intervention, cerebrovascular accident/stroke, transient ischemic attack, subarachnoid hemorrhage, cardiac insufficiency with new york heart association (nyha) class ≥ ii;

* hbsag positive or hbcab positive, and hbv-dna \> 200 iu/ml; hcv-ab positive, and hcv-rna higher than the detection limit of the research center; * according to the judgment of the investigator, the underlying condition of the subject may increase the risk of receiving the experimental drug treatment, or cause confusion in the interpretation of the toxic reactions and adverse events;
