Mantle cell lymphoma (MCL),as a kind of highly aggressive non-Hodgkin's lymphoma,is characterized by malignant B cell infiltration of lymph node,gastrointestinal tract and bone marrow.Patients suffering from MCL are prone to drug resistance or progression of disease.The 55th ASH annual meeting about MCL explored all aspects.In preclinical research aspects:new mutations including ATM,POT1 and tumor microenvironment further improved the pathogenesis mechanism of MCL.In prognostic indicators,minimal residual disease detected by molecular techniques and whole genome methylation analysis provided new tools for monitoring MCL prognosis and curative effect to guide further risk stratification and individual treatment.Exploration of high effective and low toxic side effective treatment strategies for elderly MCL patients has become a major focus of the meeting.Chemoimmunotherapy including Lenalidomide,bendamustine,rituximab and autologous stem cell transplantation provide more options for the treatment of elderly MCL patients.Novel drugs such as ibrutinib,ABT-199 and MLN8237 have shown encouraging results in preclinical trials which provide new hope for MCL patients.

Objective To screen differentially expressed microRNAs at different stages of hair cycle in a murine model.Methods This study included 30 inbred female C57BL/6 mice (age,6-8 weeks; body weight,15-18 grams).Hair growth cycle was induced in the back skin of C57BL/6 mice by application of wax/rosin followed by depilation under anesthesia witl 1% chloral hydrate.Three mice were sacrificed by cervical dislocation on day 0,8 and 20 after the induction,and skin tissue was achieved from the same depilated areas parallel to the spine.Total RNAs were extracted from the murine skin and subjected to microarray analysis of microRNA expression.Results Compared with telogen skin,the murine anagen skin showed a higher expression of miR-690,obselote-49 and miR-1308,but a lower expression of miR-291a-5p and miR-212.The expressions of miR-690,obselote-49 and miR-31 were significantly up-regulated,while those of miR-127-3p and miR-212 were downregulated in the catagen skin in comparison with the telogen skin.Conclusion Seven microRNAs are identified in this study to be differentially expressed in murine skin between different stages of hair cycle,which may provide a direction for future research.

Peripheral T-cell lymphoma (PTCL) is a group of highly heterogeneous and aggressive non-Hodgkin's lymphoma with poor prognosis under current treatment algorithm.Reports on treatment of PTCL in the 56th American Society of Hematology (ASH) annual meeting cover comprehensive aspects,among which exploration of effective low-toxicity treatment strategies for patients with PTCL is coming into the focus of this meeting.THP-COP regimen,romidepsin,bortezomib alone or in combination with panobinostat,brentuximab vedotin and stem cell transplantation provide more attractive options for both untreated and refractory/relapsed patients with PTCL,while novel drugs including Duvelisib (IPI-145),crizotinib and antiPD-1 antibody offer new hope for patients with PTCL.

Peripheral T-cell lymphoma (PTCL) accounting for 10 % to 15 % of non-Hodgkin lymphoma (NHL) is characterized highly heterogeneous and aggressive clinical course. PTCL patients are prone to suffer from chemotherapy refractory and disease progression. Reports on research progress of PTCL in the 57th American Society of Hematology annual meeting covered multiple respects of PTCL. In basic research, the novel partner genes further improve the pathogenesis mechanism of ALK+anaplastic large cell lymphoma (ALCL). For prognostic indicators, GATA-3 expression detected by immunochemical assay provide a novel tool to monitor PTCL prognosis. Belinostat-CHOP, brentuximab vedotin-CHP, romidepsin-ICE regimens and stem cell transplantation provide more options for patients with PTCL, and the novel drugs such as alisertib, darinaparsin and denileukin diftitox offer new hope for PTCL patients in preclinical trials.

AIM: To demonstrate the effects of telmisartan on the proliferation and apoptosis of U937 cells.METHODS: The proliferation ability of the U937 cells was assessed by CCK-8 assay and colony formation test with methylcellulose.The CD11b expression rate of the U937 cells was identified by flow cytometry.The apoptotic rate was analyzed by flow cytometry with Annexin V-PI double staining and Hoechst 33342 staining.The protein levels of cleaved PARP and cleaved caspase-3 were determined by Western blot.RESULTS: The results of CCK-8 assay confirmed that the viability of U937 cells was inhibited by telmisartan.The colony formation capacity of U937 cells was also significantly inhibited by telmisartan.The differentiation of U937 cells was induced by telmisartan with the expression of CD11b.The results of flow cytometry analysis with Annexin V-PI double staining and Hoechst 33342 staining identified that the apoptosis of U937 cells was induced by telmisartan in dose-dependent and time-dependent manners with the up-regulation of cleaved PARP and cleaved caspase-3 proteins.CONCLUSION: Telmisartan inhibits the proliferation and induces the differentiation of U937 cells.Telmisartan also induces the apoptosis of U937 cells through the caspase pathway.

The standardization of clinical laboratory information is an important part of standardization of medical infor-mation,and the critical means to realize this standardiaztion is to classify and code the clinical laboratory items.Earlier work has been done mainly in the United States,Europe and Japan.However,it develops later in China.Although we have had our standard,there are still some problems to be resolved.In this article,we retrospectively reviewed and compared the main contents,coding methods,standard form and applications,etc.in the above countries and regions,providing some ideas for improving the standardization of clinical laboratory information in China.[
