Clinical Study on the Treatment of Advanced Recurrent Tumors With Anticancer Mouse Characteristic Human Neutrophils

Inclusion Criteria: 1. Age 18 \~ 75 years old (inclusive), gender is not limited 2. Malignant tumor confirmed by puncture pathology/postoperative pathology, or PET-CT multi-focal high signal, clinical stage IV 3. Physical status score of 0-2 in ECOG scale 4. Expected survival time ≥3 months 5. Have measurable lesions, calculate the sum of the longest diameter of all target lesions, and report as the baseline sum diameter: the lesions can be accurately measured in at least one direction (record the longest diameter), as long as it conforms to RECIST1.1; If there are multiple lesions, a maximum of 5 lesions (no more than 2 per organ) are required; The efficacy of hematological malignancies such as leukemia can be confirmed by cytology/histology 6. more than 4 weeks have elapsed since previous drug therapy, radiation therapy and surgery; Oral fluorouracil and small molecule targeted drugs required for more than 2 weeks or within 5 half-lives of the drug (whichever is longer) 7. Laboratory tests meet the following criteria: (1) Bone marrow function: absolute count of blood neutrophils (ANC) ≥1\*10\^9/L, platelets (PLT) ≥75\*10\^9/L; (2) Liver function: serum total bilirubin (STB), bound bilirubin (CB) ≤ upper limit of normal (ULN) \*1.5, alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≤ULN\*2.5 (in the absence of liver metastasis), or ≤ULN\*5 (in the presence of liver metastasis); (3) Kidney function: serum creatinine (Cr) ≤ULN\*1.5, endogenous creatinine clearance (Ccr) ≥50 mL/min (calculated by Cockcroft-Gault formula) 8. Anti-neutrophil antibody test results are negative 9. The patient volunteered and signed the informed consent Exclusion Criteria: * 1: Uncontrolled or severe cardiovascular disease, diabetes, major heart disease, such as arrhythmia within 30 days, congestive heart failure, or severe coronary artery disease 2: HIV infection, no recent (within 30 days) use of immunosuppressive drugs other than steroids 3: Pregnant and lactating women 4: Previous history of stem cell and organ transplantation 5: Patients who have been using or are using immunosuppressants for a long time 6: Symptomatic brain metastases are not controlled 7: People who are known to be severely allergic to granulocyte infusion (or test positive for anti-neutrophil antibodies) 8: People with coagulation disorders 9: Mental disorders are not under control 10: Patients with severe autoimmune diseases 11: Cases deemed unsuitable for inclusion by the investigator
