11. The laboratory test values and the functions of important organs meet the following requirements:

1#Serology: HIV antibody(-), hepatitis B DNA(-), hepatitis C antibody(-) and no active syphilis infection; 2#Hematology: Absolute neutrophil count is greater than or equal to 1.5×10^9/L; WBC is greater than or equal to 3×10^9/L; lymphocyte count is greater than or equal to 0.8×10^9/L; Platelet count is greater than or equal to 100×10^9/L; Hemoglobin is greater than or equal to 85g/L ; 3#Chemistry: Serum ALT/AST is less than or equal to 3 times ULN,except in patients with liver metastasis who must have ALT/AST less than or equal to 5 times ULN; Serum Creatinine is less than or equal to 1.5 times ULN ; Total bilirubin is less than or equal to 1.5 times ULN, except in patients with Gilbert's Syndrome who must have a total bilirubin less than 3 times ULN; 4#Blood Clotting Parameters:Prothrombin Time(PT) and International Normalised Ratio (INR) are less than or equal to 1.5 times ULN;Activated Partial Thromboplastin Time (APTT) is less than or equal to 1.5 times ULN;For subjects who frequently take anticoagulant drugs,their blood clotting parameters can meet the value range adoptive to this special population; 5#Left ventricular ejection fraction#LVEF#is more than or equal to 50%. 12. More than four weeks must have elapsed since any prior systemic therapy (except for bridging therapy) at the time the patient receives the lymphodepletion regimen, and toxicities must have recovered to grade 1 or less (except for toxicities such as alopecia or vitiligo)

Exclusion Criteria:

1. Pregnant or lactating women.

2. History of severe immediate hypersensitivity reaction to HPV-T and any of the agents used in this study.

3. Participants with a history of organ transplantation.

4. Participants with brain metastases.

5. Any active autoimmune disease or participants with a history of autoimmune diseases that have been assessed by the investigator to be unsuitable for this study. Including but not limited to the following diseases: such as systemic lupus erythematosus, immune related neuropathy, multiple sclerosis, Guillain Barre syndrome, myasthenia gravis, connective tissue diseases, inflammatory bowel diseases(Crohn's disease and ulcerative colitis), excluding vitiligo, eczema, type I diabetes, rheumatoid arthritis and other joint diseases, Sjogren's syndrome and controlled psoriasis by local medication.

6. Active systemic infections, for example, acute infections requiring systemic antibiotic, antiviral, or antifungal treatment occur within 2 weeks before enrollment.

7. Severe liver and kidney function damage(given treatment is still uncontrollable, and biochemical indicators cannot meet the Exclusion Criteria of 11th), uncontrollable diabetes, pulmonary fibrosis, interstitial lung disease, acute lung disease, or poorly controlled hypertension (systolic pressure>160mmHg and/or diastolic pressure>90mmHg); active cardiovascular and cerebrovascular diseases, such as acute stroke, myocardial infarction, unstable angina, congestive heart failure rated as Grade II or above by the New York Heart Association, severe cardiac arrhythmias that cannot be controlled with medication, electrocardiograms show significant abnormalities (three consecutive times with an interval of at least 5 minutes) which have been assessed by the investigator that affect subsequent cellular treatment; mental illness and drug abuse, or any situation that the investigator assessments may increase the risk of this study.

8. Participants plan to receive glucocorticoid (the dose of prednisone or alternative drug is more than 10mg per day) or other immunosuppressant within 4 weeks before the administration of lymphocyte clearance. Tips: when there is no active autoimmune disease, it is allowed to use prednisone or alternative drug with a dose less than 10 mg per day; Allowing participants to use topical, ocular, intra articular, intranasal, and inhaled glucocorticoids for treatment.

9. Participants plan to receive immunomodulatory drugs (such as interferon, GM-CSF, thymosin, gamma globulin, excluding IL-2) within 4 weeks before the administration of lymphocyte clearance.

10. The investigator assessed that the subject was unable or unwilling to comply with the requirements of the study protocol.

11. With a history of other malignant tumors.

12. The participant has any disease or medical condition that may affect the safety or effectiveness evaluation of the study treatment.
