NHL
Brief summary
This study is a multicenter, non randomized, single arm, open clinical trial. The selected disease was relapsed / refractory NHL, and the disease was classified into highly aggressive lymphoma, invasive lymphoma and inert lymphoma; Highly invasive NHL included Burkitt lymphoma (BL), lymphoblastic lymphoma (LBL), high-grade B-cell lymphoma, etc; Invasive NHL includes diffuse large B-cell lymphoma, mantle cell lymphoma and peripheral T-cell lymphoma; Inert NHL contains follicular lymphoma, small lymphocytic lymphoma and marginal zone lymphoma.
Detailed description
A single car consists of scFv, hinge region, transmembrane region, costimulatory domain and zeta subunit of CD3.Prior to CAR-T cell infusion, the patients will be subjected to preconditioning treatment. After CAR-T cell infusion, the patients will be evaluated for adverse reactions and efficacy.

Patients with hematopoiesis and lymphoid tissue tumors diagnosed as relapsed and refractory by clinical diagnosis were defined as relapse or refractory 1. Primary drug resistance to standard treatment regimen; 2. Or PD occurred after at least second-line standard treatment; 3. Or the last treatment effect was SD and lasted no more than 6 months; 4. Or CD20 positive patients were ineffective or relapsed after anti-CD20 mAb treatment; 5. Or PD after autologous hematopoietic stem cell transplantation, or recurrence confirmed by biopsy within 12 months, or salvage treatment after autologous hematopoietic stem cell transplantation has no remission or recurrence after treatment. 3\. According to RECIST version 1.1 , there should be at least one measurable tumor focus; 4. Subjects with ECoG score of 0-2 5. 14 years old ≤ age ≤ 75 years old, both male and female; 6. The tumor cells were positive for CD19 or CD22 / CD30 / CD7 / CD79 by immunohistochemistry or flow cytometry; 7. The expected survival time is more than 3 months from the date of signing the informed consent； 8. Laboratory examinations meet the following conditions: hemoglobin ≥80g/L, platelet count ≥50 × 10\^9/L, absolute neutrophil count (ANC) ≥1.0 × 10\^9/L, if the investigator believes that the above inspection value is below the lower limit It is caused by tumor invading bone marrow and can be included in the group after consultation with the sponsor; 9.
