Objective This study was designed to investigate the effect of matrine on high glucose‐induced tumor necrosis factor‐α(TNF‐α)and transforming growth factor‐β1 (TGF‐β1 ) overexpression in rat peritoneal mesothelial cells(PMCs) ,and to ex‐plore the possible mechanism in the peritoneal fibrosis .Methods ology The rat PMCs were incubated in vitro ,and then assigned in‐to 5 groups on the basis of the added drug concentrations :2 .5% glucose group (n=15 ,A);Glucose + 2 .5% matrine group (n=15 ,B);4 .25% glucose group (n=15 ,C);Glucose + 4 .25% matrine group (n=15 ,D);Blank control group (n=15 ,control group , added the DMEM/F12 medium) .The levels of TNF‐αand TGF‐β1 in the supernatants were measured by ELISA method at the dif‐ferent time (24h ,48h ,72h) ,and observed the changes of PMCs under the microscope .Results Compared with the groups of A ,C and D ,the PMCs in the control group and B group were small ,round ,spindle ,irregular or intensive .The expression of TNF‐αand TGF‐β1 in the A group was lightly higher than that of the control group ,but the level in the C group was significantly higher than that of the control group (P<0 .05) .As compared with the A group ,The level of TNF‐α and TGF‐β1 expressed in the B group were decreased (P> 0 .05 ) ,but the lever in the D group was significantly lower than that of the C group ( P< 0 .05 ) . Conclusion Matrine might be helpful to resist the overexpression of TNF‐αand TGF‐β1 induced by high glucose ,and then protect the PMCs .

Purpose:To study if tamoxifen (TAM) can induce growth arrest and apoptosis of ER negative MA782 mouse breast cancer cell line and to explore the molecular mechanisims. Methods:MA782 cells were cultured in RPMI 1640 medium with TAM.The proliferative activity of cells was detected by MTT methods, and cells apoptosis by flowcytometric methods. The expression of cyclin D1, CDK4 and TGF ?1 proteins was detected by immunohistochemical methods, the semi quantification of protein expression was analyzed by pathological image analysis software.Results:TAM can induce growth arrest and apoptosis of cells. ICC results showed that MA782 cells were ER negative. There was no change of cell cycle regulators in cells with 2 ?mol/L TAM. After 48、72h with 6 ?mol/L or 10 ?mol/L TAM, the level of cyclin D1 proteins decreased from 132.5?0.02 to 129.67?0.03、126.18?0.03(6 ?mol/L) and 109.1?0.01、73.56?0.02(10 ?mol/L),CDK4 proteins decreased from 107.2?0.01 to 91.23?0.02、76.21?0.03(6 ?mol/L)and 83.52?0.02、72.03?0.01(10 ?mol/L), while TGF ?1 proteins increased from 59.72?0.02 to 83.2?0.04、121.75?0.03(6 ?mol/L)and 96.83?0.02、139.01?0.05(10 ?mol/L),The difference was significant( P

Purpose To summarize the clinical and echocardiographic characteristics of congenital quadricuspid aortic valves (QAV) so as to improve the understanding of QAV and the accuracy of preoperative diagnosis.Materials and Methods The clinical and echocardiographic data of 7 patients with QAV at the First Affiliated Hospital of Nanchang University were retrospectively studied,and the features such as the aortic valve (AV) leaf number,echo,shape,opening and closing movements,and its hemodynamics were observed and compared with surgical follow-ups.Results Five out of the 7 patients had chest tightness,chest pain,fluster,shortness of breath,and 2 others had no discomfort.The echocardiography presented that all the cases had moderate or severe aortic valve regurgitation.4 patients were diagnosed as QAV,2 patients were not diagnosed definitely,and the rest 1 was misdiagnosed.6 patients underwent aortic valve replacement and were all confirmed with QAV,among whom 2 patients were combined with infective endocarditis,and 1 patient was with aortic dilatation.All the surgical operations were successful and the patient's physical conditions were good after surgery.Conclusion Echocardiography plays an important role in diagnosis of aortic valve,but it is possible to be missed or misdiagnosed.Most QAV patients have good prognosis,but close follow-ups are needed when QAV is combined with other complex deformity or has induced secondary damages.

Objective To identify the gene locus and the mutation of DSRAD (double-stranded RNA adenosine deaminase) in a Chinese dyschromatosis symmetrica hereditaria(DSH) family. Methods After confirming the diagnosis of the DSH proband, the genomic DNA was extracted from the whole blood samples of every members of the pedigree. The DSRAD gene intervals were localized by linkage analysis and haplotype reconstruction. The mutation of DSRAD was detected by direct sequencing. Results The candidate gene was localized at the 1q region, consistent with the reported region. The direct sequencing results showed that there was a CAA→TAA transition at exon 2 of DSRAD in all affected family members, which consequently led to a nonsense mutation of Gln517Ter. Conclusion A nonsense mutation is found in the Chinese DSH family.
