Objective To inhibit the expression of matrix metalloproteinase-2(MMP-2) and matrix metalloproteinase-9(MMP-9) in human kidney tubular epithelial cell(HKC) with specific small interference RNA(siRNA),then to observe whether the expression of intercellular adhesion molecule-1(ICAM-1) on HKC could be influenced.Methods HKCs were transfected with MMP-2,MMP-9 siRNA or irrespective siRNA respectively,untransfected HKC was considered as blank control.Four groups of HKCs were stimulated with 100nmol/L phorbol myristate acetate(PMA) for 18h.Total RNA or protein of cells were extracted with Trizol and RIPA cell lysate respectively,the mRNA expression levels of MMP-2,MMP-9 and ICAM-1 were detected by real time PCR,the protein expression levels of above indexes were detected by western blotting and immunofluorescence combined with confocal laser microscopy.Results The specific siRNA could inhibit the expression of MMP-2 and MMP-9 in HKCs effectively.Immunofluorescence combined with confocal assay demonstrated that while HKCs was stimulated with PMA,the expression of ICAM-1 was up-regulated,which was significantly up-regulated in the group transfected with MMP-9 siRNA(P0.05).Conclusions The inhibitory expression of MMP-9 of HKC may up-regulate the expression of ICAM-1,implying that,besides taking part in the degradation of extracellular matrix,MMP-9 may throw an influence on the proceeding of renal fibrosis by inflammatory pathway.

Objective:This study investigated 376 adolescents' interpretations to peer rejection events. Methods:Measuring 376 adolescents' degrees of peer acceptance and their interpretations to peer rejection events by means of pen and paper questionnaires.Results:Peer-rejected adolescents presented a similar way of general interpretation to rejected events happened in other peers,however they interpret their own rejected events in a completely different way compared with popular adolescents:The main effects of peer acceptance types were significant on objective and subjective question scores(F(3,344)=3.212,P=0.023;F(3,344)=4.059,P=0.007, respectively);and there was a significant interaction effect of sex?age?peer acceptance types (F(9,344)=3.447, P

This article has shown the experiences to achieve more effective teaching results by integration of multiple teaching patterns,including case-based,problem-based learning,in the teaching of water-electrolyte metabolism and acid-base balance disorders.
