贵阳市轨道交通2号线观水路车站位于主城区某重要主干道交叉口正下方,道路两侧重要建筑密布,因此为选取合适的施工方案,通过采用MIDAS-GTS NX有限元软件建立有限元模型,分析了CRD法、双侧壁导洞法以及叠合初支拱盖法3种常用地铁车站施工方法的力学特性及其对周围环境的影响。结果表明:双侧壁导洞法引起的地表沉降和拱顶沉降最小,塑性区范围也相对较小;在拱底隆起变形方面,3种工法结果较为接近;在支护轴力方面互有优劣。通过对比优选出双侧壁导洞法作为该工程的施工方案,指导了该工程的施工,取得了良好的应用效果。

胃干细胞(GSCs)在肠型胃癌(IGC)发生中发挥重要作用。GSCs主要包括富含亮氨酸重复序列的G蛋白偶联受体-5^(+)干细胞(Lgr5^(+)SCs),肌肉、小肠和胃表达因子1(Mist1)^(+)SCs和胃窦胆囊收缩素2型受体(Cck2r)^(+)SCs等。本文综述这三种GSCs癌变的分子机制,发现经典的Wnt信号通路(cWnt)-Notch动态平衡失调驱动IGC的发生。cWnt-磷脂酰肌醇3激酶/蛋白激酶B(PI3K/Akt)或cWnt-Ras信号通路被激活和Notch信号通路被抑制是这几个胃干细胞癌变的普遍特点;激活Notch/胶质瘤相关癌基因同源物(Gli)2/哺乳动物雷帕霉素靶蛋白(mTOR)下调cWnt是癌变的另外一种机制,深入研究这两种癌变分子机制或能为IGC治疗提供新思路。
