细胞滋养层

Shortly after implantation the blastocyst wall, the trophoblast, consists of two layers of cells.

植入之后不久，胚囊的壁，即滋养细胞含有两层细胞。

Objective To study the relationship between postdate labor and the trophoblast apoptosis by observing the expression of Survivin protein in the trophoblasts of placenta.

目的 通过观察过期妊娠患者凋亡抑制蛋白Survivin在胎盘滋养细胞层的表达，探讨滋养细胞凋亡与过期妊娠的关系。

Methods Immunnohistochemistry was used to detect the expression of Survivin protein in the trophoblasts of placenta which were taken from 10 samples of postdate labor and 10 samples of fullterm labor.

采用免疫组织化学方法对10例过期妊娠和10例正常足月妊娠产妇的胎盘滋养细胞层Survivin表达进行检测和对比研究。

The expression of Survivin protein in the trophoblasts of fullterm labor was remarkably higher than that in the placenta of postdate labor.

胎盘滋养细胞层凋亡抑制蛋白Survivin表达减少，可能与过期妊娠有关。

In HM, IM and CC, the normal expression rates of Ecad were 53.3%, 31.25% and 16.67%, respectively; the strong expression rates of LN were 80%, 56.25% and 50%, respectively.

目的 探讨上皮型钙粘附蛋白和层粘连蛋白在妊娠滋养细胞疾病中的表达及意义。

Results The normal expression rates of Ecad and the strong expression rates of LN in GTD were 37.8%(28/74) and 64.86%(48/74), respectively, and were significantly lower than those in normal villus tissue.

目的 探讨上皮型钙粘附蛋白和层粘连蛋白在妊娠滋养细胞疾病中的表达及意义。

Results The artery frequency spectrum of high speed and low resistance were found in malignant trophoblastic tumors. The ulterine muscular layer in malignant trophoblastic tumor was hypervascular and the resistive index was less than 0.4. After chemotherapy, the hypervascularity decreased, RI increased higher, and β-HCG returned normal.

结果 恶性滋养细胞肿瘤子宫动脉RI值较低，为高速低阻力性动脉频谱；恶性滋养细胞肿瘤宫壁血流异常丰富，子宫肌层病灶内血管阻力指数RI.4；恶性滋养细胞肿瘤患者全身化疗取得疗效后子宫肌层血流丰富区逐渐缩小，RI呈逐渐升高趋势，血β-HCG逐渐恢复正常。

ABSTRACT:Objective To explore the expressions of Ecadherin and Laminin in gestational trophoblastic diseases and their significance.

Trophoblast cells, as the outermost covering of placental barrier, are directly bathed in the maternal blood, might be the key sites for invasion of HBV into placentae.

胎盘屏障的滋养层细胞是HBV经胎盘感染胎儿首先必须突破的第一道防线，直接与母亲血液接触，是HBV侵入胎盘的关键部位。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
