The embryonic vessels failed to invade into the labyrinthine layer of placenta, which impaired the embryonic-maternal vascular connection. These defects could not be rescued by wild-type tetraploid blastocysts, excluding the possibility that they were due to the extraembryonic tissues.

组织免疫组化分析结果显示：毛细血管腔异常扩张，排列紊乱，不能形成大血管及细致有序的血管网络；胚外中胚层来源的卵黄囊脏层扁平上皮细胞形态变圆，与内皮细胞连接受损；胚胎血管不能侵入胎盘迷路层，胚体与母体血管连接受损。

Decidual tissue is a very complex and highly concordant tiny environment between mother and embryo during pregnancy, which is constituted of the variety cells such as extravi11ous trophoblast,endometrium cells, bone marrow cells, decidua l microphage,T cells and a few B cells and so on.

正常蜕膜组织是母-胎界面间一个非常复杂而又高度协调的微环境，它由多种细胞如侵袭至蜕膜的绒毛外滋养细胞(extravi11ous trophoblast，EVT)、子宫内膜源性细胞(如上皮细胞和血管内皮细胞)、骨髓源性细胞(如大颗粒淋巴细胞、蜕膜巨噬细胞、T细胞和少许B细胞)构成，这些细胞以及由这些细胞、母体和胎儿所分泌到蜕膜的细胞因子共同形成了母-胎间信息交流的平台，并对胚胎滋养细胞"有控性"侵袭、子宫内膜的免疫容受性、蜕膜化和胎盘的形成进行精细的调控。

It is important in the formation of the umbilical cord and placenta in mammals.

对哺乳动物脐带和胎盘的形成有重要作用

Herpes simplex virus infection to the fetus through the placenta, pregnancy first 8 weeks of infection and occurrence of fetal malformations can generally mainly small head, small eyes, chorioretinitis, crystal turbidity, heart abnormalities, limb abnormalities, intrauterine growth retardation, cerebral dysgenesis, hydrocephalus, corneal cataract formation of the liver, splenomegaly, pneumonia and so on. 2, diagnosis:(1) direct examination, electron microscopy examination herpes fluid, can be found herpes virus-like particles.

单纯疱疹病毒通过胎盘传染给胎儿，妊娠头8周感染可使胎和发生畸形，一般主要为小头，小眼，脉络膜视网膜炎，晶体混浊，心脏异常，肢体发育异常，宫内生长迟缓，脑发育不全，脑积水，角膜翳形成肝，脾肿大，肺炎等。2、诊断：(1)直接检查，用电镜检查疱疹液，可发现疱疹病毒颗粒。

Sometimes no normal decidual plate forms in pregnancy, and placental villi invade directly into myometrium , as seen here.

有时，怀孕后没有正常蜕膜形成，胎盘绒毛直接侵入子宫肌层，这里看见的便是。

Those results suggested that IGF-Ⅰ is an important regulator for fetal and placental growth and development.

IGF-Ⅰ是胎儿、胎盘生长发育的重要调节因子，对巨大儿、小于胎龄儿的形成有重要作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
