Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age ≥18 years old (including boundary values), gender is not limited
2. ECOG score 0-2 points
3. Expected survival ≥6 months
4. Patients who have received immune effector cell therapy (marketed CAR-T cell therapy or dual antibody therapy) (no target), have grade 3-4 hemocytopenia after treatment, and do not recover to grade 2 within 3 weeks after conventional treatment. Defined as follows:

1\) The neutrophils again decreased to grade ≥3 within 1 week after G-CSF discontinuation, or 2) Unable to detach from red blood cell or platelet transfusion (infusion time less than one week requires re-infusion) (5) Understand the research protocol and sign the informed consent voluntarily

Exclusion Criteria
