Aim To investigate the effect of selective cyclooxygenase-2 inhibitor, NS-398, on cell apoptosis in leukemia cell line K562 cells and its underlying mechanism. Methods Apoptotic cell percentage was examined by flow cytometry(FCM). The protein expression of Bcl-2 and Caspase-3 was detected by Western blot, and the activity of Caspase-3 was checked by FCM. Results NS-398 induced the cell apoptosis in K562 cells in a dose-dependent manner. After NS-398 treatment, the expression of Bcl-2 protein was downregulated, whereas the expression of Caspase-3 protein was upregulated. Moreover,the activity of Caspase-3 was increased in a dose-dependent way after NS-398 treatment. Conclusion Selective cyclooxygenase-2 inhibitor,NS-398,significantly induced apoptosis in K562 cells. The underlying mechanism might be related to the downregulation of Bcl-2 and the activation of Caspase-3.

Aim To observe the correlation between the TPL's suppression on myofibrolbasts(MFBs)activation and TGF-β1/ERK/Smad3 pathway by performing in vivo and in vitro experiments.Methods In vitro model of MFBs activation was set up by stimulating fibroblasts with TGF-β1,and in vivo model of MFBs activation in radiated lung tissue was built by thoracic radiation on C57BL/6 mice.MFBs activation was analyzed by detecting the expression of α-SMA(using RT-PCR and Western blot)and Col Ⅰ(using RT-PCR and ELISA methods).The levels of p-ERK,p-Smad3(Ser208)and p-Smad3(Ser423)were measured by Western blot.ERK siRNA and Smad3 siRNA were used to observe the status of ERK and Smad3 in MFBs activation.Results TGF-β1 activated p-ERK/p-Smad3(Ser208)and p-Smad3(Ser423),increased the expression of α-SMA and synthesis of Col Ⅰ,which indicated MFBs activation.siRNA knockdown assay showed that both ERK and Smad3 were involved in regulating the levels of α-SMA and Col Ⅰ,and ERK influenced MFBs transformation possibly through its phosphorylation of Smad3(Ser208).TPL treatment inhibited the phosphorylation activation of ERK,Smad3(Ser208),Smad3(Ser423)in vitro and in vivo,therefore significantly reduced the level of α-SMA and Col Ⅰ,and the number of activated MFBs was decreased.Conclusion TPL mitigates radiation-induced pulmonary fibrosis by inhibiting the activation of MFBs,which is partly through suppressing TGF-β1/ERK/Smad3 pathway.

An actinomycete B37 was isolated from an intertidal marine sponge Hymeniacidon perleve, which has strong activity against Gram positive bacteria and moderate activity against tumor cells. The mycelium and spore morphology, physiological properties and 16SrDNA sequence suggested that B37 is Streptomyces pseudogriseolus. The fermentation conditions of this strain were investigated for the biosynthesis of bioactive metabolites.

Objective To examine the relationship between plasma homocysteine level and status of congestive heart failure. Methods Plasma homocysteine level was determined in 106 patients with congestive heart failure(CHF).Among them,40 patients were diagnosed as having recent onset of CHF(group 1) and the remaining 66 were receiving conventional treatment(group 2).Thirty healthy subjects were served as a control group. Results(The plasma) homocysteine levels in group 1,group 2 and the control group were(14.87?5.22),(13.25?5.45) and((7.52)?1.73) ?mol/L,respectively.The plasma homocysteine level was significantly higher in group 1 and group 2 than in the control group(P

BackgroundLaser peripheral iridotomy(LPI) can break the pupillary block,and is an effective method of treating acute primary angle closure (APAC).However,a part of APAC eyes may gradually develop a formation and extension of peripheral anterior synechia(PAS) and increased intraocular pressure(IOP) after LPI.ObjectiveTo investigate the relationship between appositional angle closure and darkroom provocative test(DRPT) in the fellow eyes with APAC after LPI.Methods Fellow eyes of APAC without PAS after LPI were studied.Ultrasounic biomicroscopy(UBM) were performed in darkness to observe whether appositional angle closure occurred and compare the relationship between the quadrants with appositional angle closure and the results of DRPT.Results Fifty-four patients were included in the study.Appositional angle closure was observed in at least one quadrant in 20(37.0％ ) of the 54 fellow eyes with APAC after LPI.Fifty-one patients were given DRPT and positive result in 9 patients( 17.6％ ).According to the quadrants with appositional angle closure,there were 5 patients with DRPT positive results in 46 patients with appositional angle closure 0 to 2 quadrants,and 4 patients with DRPT positive results in 5 patients with appositional angle closure 3 to 4 quadrants ( P =0.003 ).Bivariate correlation analysis indicated a positive correlation between the value of the increased IOP in DRPT and the number of quadrants with appositional angle closure in darkness( r =0.397,P =0.004).ConclusionsA certain proportional fellow eyes of APAC appeared appositional angle closure in darkness and DRPT positive result after LPI.The more the quadrants of appositional angle closure after LPI,the greater the likelihood of a positive DRPT.It suggests that the APAC fellow eyes and attack eyes with the same anatomical configuration still have the possibility of angle closure after LPI,and need follow-up and treatment for a long time.

Purpose To evaluate features of the left ventricular twist in patients with atrial septal defect (ASD) using speckle tracking imaging (STI) in order to guide clinical application.Materials and Methods Fifty-eight patients with ASD confirmed by ardiac ultrasound in Shanghai Children's Medical Center from October 2015 to January 2016 were enrolled in this study as case group,which were further divided into group ASD-A with 30 cases and group ASD-B with 28 cases according to the volume of right ventricular.The volume of right ventricular was significantly increased in the group ASD-A,but the volume of right ventricular was not significantly increased in the group ASD-B.At the same time,30 normal children with matched age and sex were chosen as control group.The parameters of left ventricular twist motion in each group were measured and compared by using STI.Results In group ASD-A,The basal and apical part of 6 children rotated counterclockwise.Compared with those in the control group,the basal rotation angle and apical rotation angle of left ventricular in group ASD-A were significantly higher (P＜0.01),and the peak twist and torison of left ventricular in group ASD-A were also higher (P＜0.05).Compared with those in the control group,only the apical rotation angle in group ASD-B was higher (P＜0.05),but the rest parameters of the left ventricular twist motion in group ASD-B were not statistically significantly higher (P＞0.05).Conclusion The significant increase in the volume of right heart load in ASD impacts on the basal and apical rotation of left ventricular.
