Brief summary: This is a single center, single arm, open-lable phase I study to determine the safety and efficacy of CD19-STAR-T cells in patients with refractory and relapsed B-cell malignancies (such as NHL and ALL ).

Detailed description: This Phase I study is designed as a pilot trial evaluating the safety and of CD19-STAR-T cell therapy in subjects with refractory and relapsed B cell malignancies. Subjects will receive cytoreductive chemotherapy with cyclophosphamide and fludarabine on days -5, -4 and -3 followed by infusion of CD19-STAR-T cells. Safety and efficacy of CD19-STAR-T cells therapy will be monitored. The purpose of current study is to determine the clinical efficacy and safety of CD19-STAR-T cells therapy in patients with refractory and relapsed B-cell malignancies.

Eligibility criteria: Inclusion Criteria:

1. Relapsed and refractory CD19 positive B-cell acute malignancies with:

   * Relapsed after competed remission, could not get competed remission after at more than 1 course of chemotherapy (including MRD≥0.1%);
   * MRD≥0.1% after allogeneic hematopoietic stem cell transplantation(HSCT), or recurrence after complete remission or MRD ≥ 0.1% after HSCT;
   * Refractory: at least two courses of chemotherapy did not achieve complete remission or MRD ≥ 0.1%;
2. Patients must have evaluable evidence of disease, including minimal residual disease (MRD);
3. Ph + patients who meet the following criteria can register:Failure to tolerate TKI or TKI treatment failure, or failure to transplant;
4. Ages 1 to 70 years, including boundary values;
5. ECOG score 0-3 points;
6. Women of childbearing age (15-49 years old) must receive a pregnancy test within 7 days prior to initiation of treatment and the results are negative; male and female patients with fertility must use an effective contraceptive to ensure 3 months after discontinuation of treatment during the study period not pregnant inside.

5. GVHD ≥ 2 or receiving anti-GVHD treatment;
6. Received allogeneic cell therapy within 4 weeks, such as donor lymphocyte infusion(DLI);
7. Subject received anti-tumor treatment (chemotherapy, mAb, or hormone) for less than 1 week;
8. Central nervous system leukemias that is symptomatic or uncontrolled by systemic chemotherapy and intrathecal chemotherapy (a large number of tumor cells in CSF, white blood cell count \>15WBCs/mL);
9. intracranial hypertension or unconsciousness; respiratory failure; diffuse vascular internal coagulation;
10. pregnant or lactating women;
11. The patient does not agree to use effective contraception during the treatment period and for the next 3 months;
12. Patients who participate in other clinical studies at the same time;
13. The investigator believes that there are other factors that are not suitable for inclusion or influence the subject's participation or completion of the study.
