The structure of the dual-target CAR-T of CD19 \\& CD22 is designed with a 4-1BB costimulatory domain and an antigenic recognition region with a tandem structural sequence to recognize CD22 or CD19 by a single structure. CD19 \\& CD22 bispecific CAR-T cells can identify CD 19 or CD 22 with the advantage that the single target CAR-T does not have, reducing the possibility of target loss. The structure has been optimized to enhance the safety to treat B cell-derived hematological tumors (at least CD19 positive or CD22 positive).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '3 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.CD 19 + / CD 22 + B cell hematological tumor was confirmed by pathological and histological examination, and the patient met the following criteria for relapsed or refractory B cell hematological tumor:\n\n1.
