Inclusion Criteria:
1. Age range from 18 to 75 years;
2. ECOG performance status: 0-2;

2. Patients with evidence of CNS involvement (baseline cerebrospinal fluid, imaging, symptoms);
3. Special types of diffuse large B-cell lymphoma patients who are not suitable for induction therapy with R-CDOP, such as PMBCL, double-hit large B-cell lymphoma, etc;
4. Clinically significant cardiac conditions, including severe cardiac insufficiency: New York Heart Association (NYHA) cardiac insufficiency class IV, unstable angina, acute myocardial infarction within 6 months prior to screening, congestive heart failure, and Q-Tc interval greater than 500 ms;

3. Carcinoma in situ of the cervix that has been adequately treated with no evidence of disease;
7. Had significant coagulation abnormalities;
8. Any previous antilymphoma therapy other than short-term corticosteroids (up to 10 days);
9. Those with severe active infection;
10. Other serious, uncontrolled concomitant conditions that may affect protocol adherence or interfere with interpretation of results include uncontrolled diabetes mellitus, or pulmonary disease (interstitial pneumonia, obstructive pulmonary disease, and a history of symptomatic bronchospasm), hypertension, and others;
11. HBV (HBsAg positive and HBV-DNA ≥ 104 IU / ml), HCV (HCV antibody positive and HCV-RNA measurable); And subjects with other acquired, congenital immunodeficiency diseases, including but not limited to those with HIV infection;
