   A. Women of reproductive age (15-49 years) must undergo a pregnancy test with negative results within 7 days before starting treatment; B. Women of reproductive age should use effective contraception for at least 120 days after the last dose of the study drug (contraceptive success rate of at least 99%). The subject should communicate with the available contraceptive methods with at least 99% success rate and confirm the understanding of the period; C.

Total bilirubin ≤1.5× upper limit of normal value (ULN) (< 3 TIMES ULN for patients with Gilbert syndrome, cholestasis caused by hilar compression adenosis, biliary obstruction caused by liver involvement or lymphoma); E. Alanine aminotransferase/aspartate aminotransferase (ALT/AST) ≤2.5×ULN or ≤5×ULN when liver invasion is present; F. Creatinine clearance ≥40ml/min using the cockcroft-gault equation or glomerular filtration rate ≥40ml/min/1.73m2 using the modified renal disease diet formula; G. Lipase ≤1.5×ULN.

Exclusion Criteria:

1. Patients known to be allergic to the drug Chidamide;
2. Lymphoma involves the central nervous system;
3. Known human immunodeficiency virus (HIV) infection or immunopositive test;
4. Viral infections that cannot be controlled by antiviral drugs, such as herpetic virus infection, acute or chronic active hepatitis B, acute or chronic active hepatitis C, etc. [Note: chronic hepatitis B virus (HBV) carriers or non-active hepatitis B surface antigen (HBsAg) positive subjects and HBV-DNA lower than the detection limit can be included in the group; hepatitis C virus (HCV) antibody negative can be enrolled, HCV antibody positive patients need to be tested for HCV-RNA, if negative can be enrolled];
5. Presence of active infectious disease requiring treatment;
6. Received live vaccine within 30 days prior to enrollment;
7. Active autoimmune disease requiring systemic treatment within 12 months prior to enrollment (i.e., disease-modifying drugs, corticosteroids, or immunosuppressive drugs). Note: Alternative therapies (such as thyroxine, insulin, or physiologic corticosteroid replacement for adrenal or pituitary dysfunction) are not considered a systemic treatment;
8. History of severe allergic reactions;
