In this article , model of geological conception in panzhihua - xichang area is established , and then the authors used gis as the tool to analyze the pge ore - forming geological conditions , including geological structure , emeishan basalt , basic - ultrabasic rock and pge geochemical abnormal 本文在建立攀西地区铂族元素矿床地质概念模型的基础上，用地理信息系统( gis )分析了该地区的铂族元素成矿地质条件，包括地质构造、峨眉山玄武岩、基性一超基性岩和铂族元素地球化学异常特徵。
Prostaglandin e2 ( pge2 ) is important for blastocyst spacing , implantation and decidualization in the rodent uterus . pge synthase ( pges ) catalyzes the isomerization of pgh2 to pge2 . there are at least three isoforms of pges , including glutathione - dependent and membrane - associated pges ( mpges ) , glutathione - independent and membrane - associated pges ( mpges - 2 ) , and glutathione - dependent cytosolic pges ( cpges ) 目前的研究表明至少存在三种不同类型的pges ，即膜相关谷胱甘肽依赖的pges ( mpges ) ，膜相关谷胱甘肽非依赖型的pges ( mpges - 2 )和可溶性谷胱甘肽依赖型pges ( cpges ) 。
