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 discuss the use of knowledge graph technology to connect various trivial and fragmented knowledge in various medical information systems and support comprehensive knowledge retrieval and intelligent medical applications such as Q & A and clinical decision support.Methods Based on the construction of medical field ontology and semantic labeling of medical knowledge base,the medical knowledge graph was constructed and applied to intelligent medicine,with chronic disease taken as an example.Results The construction method of medical knowledge graph and its application in semantic analysis,reasoning and disease-assisted diagnosis system based on medical knowledge base were put forward.Conclusion The application of intelligent medicine based on knowledge graph will play an important role in contradiction between the supply of high-quality medical resources and increasing medical requirements.

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.

In recent years,the role of phosphodiesterase 5(PDE5)has been highlighted in the development and progression of neurological disease.PDE5 inhibitors show significant effect of neruoprotection,which may be related with some effects such as resistance to stroke,anti-oxidation,inhibition of neuroinflammation and amelioration of cognitive deficits.Based on the domestic and overseas researches about PDE5,this review systematically summarized the neuroprotection of PDE5 and their related mechanisms.

Objective To induce the experimental corneal neovascularization(CRNV) by alkali burn,and explore the methods for quantitative analysis of CRNV and observation of permeability of CRNV. Methods Thirty-six C57BL/6 mice were selected and divided into experiment group(n=30) and control group(n=6).For the experiment group,alkali burn was induced by application of filter paper with 1mol/L sodium hydroxide to the cornea for 5 s.For the control group,no intervention was conducted.Areas of CRNV were measured on day 4,7,10 and 14 after alkali burn.Histological examinations of cornea were performed with HE staining on day 3, 7,10,16 and 28 after alkali burn.On day 10,endothelial cell marker CD31 was used with immunohistochemical staining for CRNV counting,and fluorescence angiography(FA) was employed to reveal the permeability of CRNV.Corneal ulceration and hyphema were observed everyday.Results CRNV developed after alkali burn,and extincted afterwards.Axenic coneal ulceration and hyphema were frequently observed,with the incidences of 6.7% and 10.0%,respectively.Histologic changes of corneal tissues at different time points could be observed with HE staining.On day 10, CRNV could be labeled and counted with immunohistochemical staining for CD31 antibody,and the permeability of CRNV could be detected by FA. ConclusionCRNV counting with immunohistochemical staining for CD31 antibody and measurement of area of CRNV are appropriate methods for quantitative analysis of CRNV.FA is an effective method in the detection of permeability of CRNV.

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.

OBJECTIVE:To provide reference for rational use of analgesic drugs for advanced cancer,moderate to severe pain. METHODS:The data of narcotic drugs and first type psychotropic drugs were collected from hospital information system of a third grade class A hospital during 2012-2014,and then analyzed in respects of amount,consumption sum and DDDs,etc. RE-SULTS:The amount of narcotic drugs and first type psychotropic drugs kept stable basically,and the consumption sum of them during 2012-2014 was 1 566 289.92 yuan,1 525 220.23 yuan and 1 531 277.44 yuan. The consumption sum of Morphine hydrochlo-ride tablet increased the fastest,increasing by 89.78% in 2013 and 142.81% in 2014,compared with the year before;those of other drugs had negative growth rate. DDDs of Morphine hydrochloride sustained-release tablets were the highest among all the narcotics and first type psychotropic drugs and increased year by year,increasing from 26 848.00 in 2012 to 47 158.00 in 2014. CONCLU-SIONS:The use of narcotic drugs and first type psychotropic drugs conform to the specifications,but they still need strict supervi-sion to promote safe and effective use of them in the clinic.
