. Gender unrestricted, age ≥5 years;

. The patient or their legal guardian agrees to participate in this clinical trial and signs the informed consent form, indicating their understanding of the trial's purpose and procedures and willingness to participate;

. Peripheral blood B cells confirmed by flow cytometry to express CD19, with a B cell count >5 cells/uL;

. If previously treated with B cell-targeted therapy, peripheral blood B cell count at screening has returned to normal or above the pre-treatment level;

Disqualifiers

. History of malignancy (except for basal cell or squamous cell skin cancer or carcinoma in situof the cervix that has been excised and cured for at least 5 years), or current malignancy.

. Known allergy, hypersensitivity, intolerance, or contraindication to CD19/BCMA CAR-NK cells or any component of the drugs that may be used in the study (including fludarabine, cyclophosphamide, and tocilizumab), or subjects who have experienced a severe allergic reaction in the past.

. Evidence of severe active viral or bacterial infection, or uncontrolled systemic fungal infection at screening or baseline visits, or subjects with active or uncontrolled infection requiring parenteral antimicrobial therapy.
