Aim To look for novel small-molecule inhibitors of CDK9 through structure-based virtual screening and biological activity determination.Methods Homology modeling of CDK9 was based on the 3-D structure of other cyclin-dependent kinase family members,and then virtual screening by DOCK(molecular docking)of database of small molecule was carried on.MTT method was used in inhibition of tumor cell growth in vitro,while Western blot was used for further study of molecular mechanisms.Results From the top 1000 compounds with the best DOCK energy score,27 compounds were selected for biological assay based on the diversity of chemical structure and functional group.12 of 27 selected compounds showed significantly inhibition activity on tumor cell proliferation,and only one compound in 12 with half-maximum inhibition concentration(IC50)values less than 20 ?mol?L-1 named C-21 was selected for further molecular mechanism study.The western blotting data showed C-21 compound could effectively inhibit CDK9 from phosphorylating large subunit C-terminal of RNA polymerase Ⅱ in a dose-dependent manner.Conclusions Through homology modeling,virtual screening by computer,determination of biological activity and experimental studies of molecular mechanism,a new promising lead compound targeted for CDK9 was found and confirmed.

Objective The clinical manifestations of cerebral infarction caused by acute basilar arterial occlusion are complex.The purpose of this study is to explore the relationship between lesion location and onset symptoms of cerebral infarction caused by acute basilar arterial occlusion.Methods Fifty three patients diagnosed with cerebral infarction caused by acute artery occlusion were collected from Nanjing Stroke Registry.They were hospitalized in Jinling Hospital from January 2007 to July 2016 and were divided into sudden onset group and progressive onset group.Their clinical and digital subtraction angiography data were analyzed retrospectively.Results Middle and distal segment of the basilar artery occlusions were usually found in sudden onset group.Patients in progressive onset group were more likely to present with proximal segment of the basilar artery occlusions.Significant statistical difference was found between two groups (P<0.05).Logistic regression analysis showed that the symptoms of patients with proximal segment basilar artery occlusion tended to be progressive onset, compared with patients affected by distal segment occlusion (OR=14.77,95%CI:1.57-139.00, P=0.019).Conclusion There was significant relationship between lesion location and onset symptoms of cerebral infarction caused by acute basilar arterial occlusion.Early diagnosis and timely treatment may improve clinical prognosis in patients.

Objective To explore a rapid and accurate method for the diagnosis of smear negative tuberculosis meningitis (TBM). Methods Sixty-seven patients with TBM were selected from Tianjin Haihe Hospital from June 2014 to June 2016, and 118 patients with non-tuberculous meningitis (NTBM) in the same period were chosen as control group, including bacterial meningitis (BM) group (n=61) and viral meningitis (VM) group (n=57). The laboratory routine, biochemical and immune indicators were tested with the specimens of both the blood and cerebrospinal fluid of all the patients. The Logistic regression equation was established for the diagnosis of TBM, and the diagnostic efficacy of which was evaluated by the receiver operating characteristic curve (ROC). Results The predictive regression equations of the TBM with BM, VM and NTBM (BM + VM) were obtained when BM group was used as a control: PRE_BM=1/1 +e-(-5.298+0.196 × ESAT-6+ 0.119 × CFP-10-2.968 × PCT+2.206 × ADA_CSF+0.705 × GLU_CSF+0.093 × LDH_CSF), PRE_VM=1/1+e-(-6.907+0.394 × ESAT-6-0.120 × Na+2.633 × ADA_CSF-0.088 × Cl_CSF) and PRE_NTBM=1/1+e-(0.683+0.099×ESAT-6+0.063×CFP-10-2.645×PCT+1.393×ADA_CSF+1.342×TbAb_CSF)respectively. When BM group was served as a control, the sensitivity, specificity, positive and negative predictive values of the regression for the diagnosis of TBM were 97.01%(89.63%-99.64%), 98.36%(91.20%-99.96%), 98.48%(91.84%-99.96%) and 96.77%(88.83%-99.61%), respectively.When VM group was served as a control, which were 94.03%(85.41%-98.35%), 94.74%(85.38%-98.90%), 95.45%(87.29%-99.05%) and 93.10%(83.27%-98.09%), respectively. When NTBM group was served as control, which were 94.03%(85.41%~98.35%), 90.68%(83.93%-95.25%), 85.14%(74.96%-92.34%) and 96.40%(91.03%-99.01%), respectively. Conclusion The predictive regression equation could be used as early diagnostic TBM with high sensitivity and specificity, which should be popularized in clinical practice, while, according to the higher negative predictive value, the negative results of which could be used to rule out of the TBM and non-empirical medication.

Objective To investigate the correlation between asymmetric dimethylarginine (AD-MA) and endothelial dysfunction in patients with uremia.Methods Uremic patients who did not receive hemodialysis were defined as A group (n =40) ; uremic patients who had received hemodialysis were divided into B group (n =45) ;healthy people were defined as C group (n =20) ;and chronic kidney disease (stage 2 ～ 4) patients were defined as D group (n =20).The diameter of intima-media thickness,and endothelium-dependent or independent dilation (EDD or EID) of radial artery in right forearm were detected with diasonography.The levels of ADMA were determined by high-performance liquid chromatography.Results Compared to C group,the levels of ADMA in A,B and D groups were significantly increased [C:(0.78 ±0.19) μmol/L,A:(1.51 ±0.16) μ mol/L,B:(1.13 ±0.14) μmol/L,D:(0.92 ±0.11) μmol/L; P ＜0.05].Compared to A group,the levels of ADMA were significantly decreased in B group (P ＜0.05).EDD and EID were decreased significantly in A,B and D groups compared to C group [EDD:C:(13.52±1.73)％ vs A:(7.32 ±0.54)％,B:(9.02 ±0.86)％,D:(10.13 ±1.25)％,P ＜0.05;EID:C:(14.45±1.85)％ vsA:(10.37 ±1.51)％,B:(9.54±1.39)％,D:(11.17±1.56)％,P ＜0.05].EDD in B group was significantly lower than A group (P ＜0.05).In group A,a negative correlation was found between EDD and the level of ADMA (r =-0.81,P =0.020).Conclusions ADMA level was significantly increased in uremic patients.A close correlation existed between ADMA and endothelial dysfunction of radial artery.

Previous study on TNFRl-mediated hepatocyte apoptosis has been implicated in the development of fulminant viral hepatitis.To interfere with the potentially effective target,plasmid named p-mTNFR1shRNA complimentary to the sequence responsible for mTNFR1 was also constructed and further confirmed by sequence analysis.To investigate the effect of mTNFR1shRNA plasmid on mTNFR1 expression in vivo and the disease progress in MHV-3 induced fulminant hepatitis mice model.By hydrodynamic injection of mTNFRlshRNA plasmid,the survival rate of mice,hepatic pathological change were examined and compared between mice with/without mTNFR1 shRNA plasmid intervention.The expression of mTNFR1 was detected by Real-time PCR,immunohistochemistry staining.The mTNFR1 shRNA plasmid significantly reduced mTNFR1 expression in vivo,markedly ameliorates inflammatory infiltration,prolonged the survival time period and elevated the survival rate from 0 up to 13.3% in Balb/cJ mice with MHV-3 induced fulminant hepatitis.This study was designed to explore the opportunity of RNA interference technique in inhibiting TNFR1 expression,which has been reported to be involved in the development of a variety of diseases including fulminant viral hepatitis and severe chronic hepatitis B.
