  1. Age: 18 years to 75 years at the time of consent;
  2. Diagnosis by cytology or histology, failure to standard treatment (including disease progression and/or adverse reactions are not tolerated) or are judged by the investigator to be unsuitable for the use of existing standards Treatment methods for patients with advanced solid tumors, including but not limited to kidney cancer, non-small cells Lung cancer, stomach cancer, colorectal cancer, melanoma, etc. Participants are required to have a minimum of menstruation Through first-line treatment.
  3. At least one resectable lesion that has not received radiotherapy or other local therapy within 28 days, and the weight of the tissue must be ≥ 0.050g；or resectable lesions capable of producing sufficient TIL;
  4. At least one measurable target lesion, as defined by RECIST v1.1，that has not received radiotherapy or other local therapy unless these therapies occurred 28 days ago and target lesion shows significant progression;
  5. ECOG score 0-1;
  6. Expected life-span more than 3 months;
  7. Adequate organ and bone marrow function:

     Absolute count of neutrophil ≥1.5×10\^9/L; Platelet count ≥90×10\^9/L; Hemoglobin ≥ 90g/L; AST, ALT≤2.5×ULN (subjects with liver metastasis ≤5×ULN); Totol bilirubin ≤1.5×ULN（Gilbert syndrome≤3×ULN）; Serum creatinine ≤1.5×ULN, or estimated creatinine clearance (CrCl)≥60 mL/min (Cockcroft-Gault formula); Activated partial thromboplastin time (APTT) ≤1.5×ULN, while international normalized ratio (INR) or prothrombin (PT) ≤1.5×ULN;
  8. Left ventricular ejection fraction (LVEF) ≥ 50% detected by echocardiography; Arrhythmias that do not require treatment, the QT interval (QTcF) corrected by the Fridericia method is ≤ 470 ms (QTcF is calculated using the Fridericia formula, i.e. QTcF=QT/(RR \^ 0.33), RR is the standardized heart rate value, RR=60/heart rate); If there is an abnormality during the first inspection, it can be retested twice with an interval of at least 5 minutes, and the overall result/average value should be taken to determine the qualification; Basic blood oxygen saturation in indoor natural air environment\>91%;
  9. Test subjects must have recovered from all prior therapy-related toxicities to ≤Grade 1 according to Common Terminology Criteria for Adverse Events (CTCAE) v5.0; except for alopecia (tumor resection);
  10. Test subjects with child-bearing potential must be willing to practice approved highly effective methods of contraception at the time of informed consent, and continue within 1 year after the completion of treatment;
  11. Be able to understand and sign the informed consent document.

Exclusion Criteria:

* Patients with any of the following criteria will not be allowed to participation:

  2. Test subjects have any uncontrollable clinical problems (including but not limited):

     hypertension poorly controlled by medication (blood pressure ≥160/100mmHg at rest after taking medication); poorly controlled diabetes; cardiac disease (New York Heart Association class Ⅲ/Ⅳ congestive heart failure or heart block);
  3. Test subjects who have active major medical illnesse(es) of the cardiovascular (within 6 months prior to enrollment), including deep vein thrombosis or pulmonary embolism; myocardial infarction; severe or unstable arrhythmia or angina pectoris; percutaneous coronary intervention, acute coronary syndrome, coronary artery bypass grafting; cerebrovascular accident, transient cerebral ischemia Seizures, cerebral embolism;
  4. Active autoimmune diseases that require systemic treatment during the study period (eczema, vitiligo, psoriasis, alopecia or Grave\'s disease that do not require systematic treatment in the past two years, other autoimmune diseases that are not expected to recur, hypothyroidism that only requires thyroid hormone replacement therapy, and type I diabetes subjects that only require insulin replacement therapy can be included);
  5. Organ transplantation and a history of hematopoietic stem cell transplantation;
  6. Any immunosuppressive drugs, such as steroids, have been used within 4 weeks prior to tumor tissue sampling, or the researcher has determined the presence of comorbidities that require the use of immunosuppressive drugs during the trial period. However, physiological doses of glucocorticoids (i.e. ≤ 12 mg/m2/day of hydrocortisone or other hormones within the equivalent dose range after equivalent dose conversion) are allowed, and steroid drugs are allowed for intranasal or local use;
  7. Individuals who have received systematic anti-tumor therapy within 4 weeks prior to pre-treatment (including those who have participated in other clinical trial drug treatments; those who have metabolized 5 drugs with a half-life of less than 4 weeks, whichever is shorter) or those who plan to participate in other intervention clinical trials during the study period;
  8. Presence of acute or chronic infection:

     HIV positive, Treponema pallidum antibody positive, or clinically active hepatitis B and C, including virus carriers (excluding HBsAg and/or HBeAg positive individuals for hepatitis B; excluding HCVAb positive individuals for hepatitis C);Active infections or active tuberculosis infections that require systemic treatment;
  9. Vaccinated with the new coronavirus vaccine within 4 weeks propr to screening, or who have received a live vaccine within 3 months, or who plan to receive live vaccine during the trial;
  10. Major organs underwent surgery (excluding needle biopsy) or significant trauma within 4 weeks before screening；required elective surgery during the study;
  11. Patients who have surgical complications or delayed healing prior to screening, and have been determined by the researchers to increase the risk of gonorrhea pretreatment, adoptive TIL therapy, and IL-2 adjuvant therapy;
  12. Test subjects who have had another primary malignancy within the previous 5 years, excluding basal cell carcinoma of the skin, squamous cell carcinoma of the skin and/or carcinoma in situ after radical resection;
