With the further study on heterogeneity and molecular mechanism of diffuse large B-cell lymphoma (DLBCL),many novel targeted drugs have been developed,which also showed clinical benefit in early-stage studies.Therapeutic targets for DLBCL mainly include the surface antigens of B lymphocyte,B cell receptor signaling and the cellular microenvironment.Several new clinical trials about targeted therapy for DLBCL had been reported in the 55th ASH annual meeting,and the results were encouraging.The advances in this field will be summarized in this paper based on the new reports in the 55th ASH annual meeting.

Chimeric antigen receptor T cells (CAR-T), one of the most promising cancer immunotherapy, has attracted much attention in the 57th American Society of Hematology (ASH) annual meeting. CAR-T therapy has obtained significant effect on leukemia and lymphoma and the latest research results are also inspiring in the 57th ASH annual meeting. It is an important task that how to combine CAR-T therapy with the traditional methods of treatment and the immune checkpoint blocking antibodies and small-molecule-targeted drugs to achieve the best effect. This paper will review the progress of CAR-T in the treatment of hematologic malignancies.

Outcome of patients with adult acute lymphoblastic leukemia (ALL) is poor,and even worse among patients with relapsed/refractory ALL (R/R ALL).New treatments must be taken to overcome drugresistance to conventional chemotherapy for ALL.Humanized monoclonal antibody and chimeric antigen receptor gene modified T cells have become the focus of treatment in ALL.Lots of clinical trials in multiple research centers are in progress,and the results constantly upgrade which is effectively bring better curative effect and prognosis for R/R ALL patients.This is one of the hot topics at the 56th ASH annual meeting.

0.05).Conclusion:The combination of TCM with western medicine was superior to simple western medicine in treating multiple sclerosis.Regulation of cytokines(TNF-? and IL-12 p40) in plasm may be partial reasons for the clinical effects of treatment based on syndrome differentiation.

With the further study on molecular pathogenesis of multiple myeloma (MM),lots of novel targeted therapies emerged into clinical trials,which improved the response rate and life quality of MM patients.In the 56th American Society of Hematology (ASH) annual meeting,a series of special reports about latest developments in targeted therapy for MM patients were published.Efficacy was improved significantly by these reagents,which may provide the new treatment strategies for MM patients.The advances in the novel targeted therapies will be summarized in this paper based on the new reports in the 56th ASH annual meeting.

Next-generation sequencing (NGS) platforms have recently evolved to provide an accurate and comprehensive means for the detection of molecular mutations in acute myeloid leukemia(AML).The 54th ASH annal meeting reported lots of studies on NGS in AML,reflect the important role of the NGS technology in modern diagnosis and treatment of blood diseases and the impact on the future development of the blood disease.

Objective To investigate the apoptosis of cell line HL-60 induced by matrine and its possible mechanism. Methods CCK-8 assay was used to observe the proliferation inhibitation of HL-60 cells treated with matrine. FCM was applied to detect apoptotic cells and mitoehondrial transmembrane potential.Spectrophotometry was used to detect the activity of Caspase-9. Results Matrine (0.25-2.0 mg/ml) could significantly inhibit proliferation of HL-60 cells (F=67.83, P ＜0.05). Ater 48 hours, the apoptosis rate increased obviously in dose dependence (t = 4.685, 6.300. 9.641, 6.786, P ＜0.05). Within 48 hours, the mitochondrial transmembrance potential of HL-60 cells treated with matrine (1.0 mg/ml) gradually decreased (F = 54.83, P ＜0.05), and the activation of Caspase-9 gradually decreased in time dependence (F = 72.31,P ＜0.05). Conclusion Matrine can induce apoptosis of HL-60 cells by reducing mitochondrial transmembrance potential and activating Caspase-9.

The clinical application of biological immunotherapy such as chimeric antigen receptor T cells (CAR-T) and novel targeted therapy has explored a new therapy for multiple myeloma (MM) treatment. Targeting B-cell maturation antigen (BCMA), allogeneic CAR-T, antibody-drug conjugate (ADC) and bispecific antibody targeting BCMA have achieved remarkable efficacy and safety in many clinical studies. This article introduces the latest immunotherapy for MM at the 62nd American Society of Hematology (ASH) Annual Meeting.

Numerous targeted therapies emerged into clinical trials, which improved the response rate and life quality of multiple myeloma (MM) patients. Series latest developments at targeted therapy for MM patients were reported on 58th American Society of Hematology (ASH) Annual Meeting, especially the results of combination with these novel agents showed a major highlight of this meeting. The advances in the novel targeted and biological therapies will be summarized in this paper.

Objective To separate the SO-Rb 50cells antigen corresponding to the monoclonal antibody of anti-retinoblastoma. Methods The antigen corresponding to the monoclonal antibody of anti-retinoblastoma was separated elementarily by ion-exchange chromatography, and was identified by dot-blotting using the monoclonal antibody of anti-retinoblastoma. The target protein band of the antigen was separated in light of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Results A special unmixed band of SO-Rb 50cells antigen was separated with the relative molecular weight of 83?103. Conclusion The antigen corresponding to the monoclonal antibody of anti-retinoblastoma could be separated from SO-Rb 50cells.
