6. Age 18-80, male or female;
7. Karnofsky Performance Status (KPS)≥80;
8. Stable vital signs and expected survival at least 12 weeks.
9. If HBsAg or HBcAb is positive, HBV-DNA < 200 IU/ml and to receive anti-HBV therapy ((Entecavir or tenofovirdisoproxil) for at least 14 days prior to the start of study treatment;
10. Blood Routine: WBC≥2.5×109/L, PLT≥60×109/L, Hb≥9.0g/dL, LY≥0.4×109/L;

12. Be able to understand and sign an informed consent form

Exclusion Criteria:

1. With uncontrolled active infections;

12. With a history of allergic reactions attributed to compounds of similar chemical or biological composition used in the study;
13. Have participation in clinical trials of any other investigational agents within 3 months before study treatment initiation.
14. Had received cell therapy previously but ineffective,after physical examination not allowed to received CAR-NK therapy by investigator's judgement;
15. Pregnant or lactating women;
16. Inappropriate to participate in this clinical trial by investigator's judgement.
