Brief summary: A single arm, open-label, dose-escalation study to evaluate the safety and clinical activity of ThisCART22 (Allogeneic CAR-T targeting CD22) in patients with relapsed and/or refractory non-Hodgkin's B cell lymphoma (r/r B-NHL).

Detailed description: ThisCART22 cell is a non-gene-editing allogeneic CAR-T cell targeting CD22. This study is designed to evaluate the safety and clinical activity of ThisCART22 in patients with CD22 positive, relapsed and/or refractory non-Hodgkin's B cell lymphoma (r/r B-NHL).

Eligibility criteria: Inclusion Criteria:

1. Age 18-70 years old, no gender and race limited;

3. CD22 were positive by histopathology and/or cytology diagnosis；
4. Patients with relapsed and/or refractory non-Hodgkin's B cell lymphoma (r/r B-NHL)；
5. Relevant indicators for disease or assessment within 4 weeks after the last treatment;
6. Quality of Life Score (KPS) \>50%；
7. Subject has adequate organ function at screening, cardiac ejection fraction ≥ 40%, no evidence of pericardial effusion as determined by an echocardiogram (ECHO); serum ALT/ AST \<3 upper limit of normal (ULN); bilirubin\<2.0 mg/dl; serum creatinine ≤1.6 mg/dl and/or BUN ≤ 1.5 mg/dl;
8. No remission or relapse after hematopoietic stem cell transplantation or autologous somatic immunotherapy;
9. Unsuitable conditions for stem cell transplantation;
10. Signed informed consent form (ICF).

Exclusion Criteria:

1. Women in pregnancy or lactation;
2. In active infection including hepatitis B, hepatitis C, HIV, or other fatal viral and bacterial infection；
3. The absolute count of nonprimary neutrophil \< 0.75×10\^9/L or platelet count \< 50×10\^9/L;
4. Abnormal vital signs and failure to cooperate with examination;
5. Patients with mental or psychological diseases who cannot cooperate with treatment and efficacy evaluation;
6. Highly allergic constitution or history of severe allergy;
7. Patients with systemic infection or severe local infection requiring anti-infection treatment;
8. Patients with severe autoimmune diseases;
9. Presence of any other conditions that are unsuitable for this study as judged by the investigator.
