  Objectives: To investigate whether the miR-21 could down-regulate FASLG to regulate the proliferation and apoptosis in glioblastoma cancer stem cells(GSCs).Methods: Real-Time quantitative PCR was applied to evaluate the expression level of miRNA-21 in glioblastoma and normal brain tissue samples,and the expression change of miRNA-21 between GSCs and non-GSCs was also detected.The proliferation and apoptosis ability of miR-21 in GSCs were analyzed by MTT and flow cytometry assay after pre-miR-21 or anti-miR-21 transfection.For the regulation mechanism analysis of miR-21,TargetScan,PicTar and miRBase were used to predict the possible target gene of miR-21.Luciferase activities assay and western blot were used to reveal the predicted target gene of miR-21 were direct and specific.RNA interference technology was used to confirm the proliferation and apoptosis regulation of miR-21 was directly induced by FASLG.

为了缓解城市雨水管理的困局,研究透水沥青路面、透水混凝土路面在市政道路的应用,研究结果表明,透水路面可以储水、排水,还透过地表空隙蒸发。透水路面面层和基层的功能与传统路面不同,透水沥青路面和混凝土路面各有优缺点。总结了透水路面结构和材料方案及施工等技术问题。
近年来随着人们生活节奏及生存环境的改变,胃溃疡的发病率呈现逐年增加的趋势,发病人群也愈发年轻化。为了进一步探索胃溃疡的发病机制及其系统、高效的诊疗方法,临床上已经建立多种胃溃疡动物模型,如应激型、化学因素型、幽门结扎型、螺杆菌感染型及病证结合型。笔者拟在回顾胃溃疡中西医病因病机及诊断标准的基础上总结现有胃溃疡模型的造模方法和优缺点,发现非损伤应激法(束缚应激、束缚浸水应激及束缚冷冻应激等)+中医证
