The change of MMPs and TIMPs expression might be involved in the effect of high levels of hCG on trophoblast or choriocarcinoma cell invasiveness.

高浓度(25 IU/ml)的hCG可能通过改变蛋白水解酶及其抑制因子的表达而减弱滋养细胞的侵袭性。

Methods: The expression of survivin in the trophocyte of 14 cases of normal early gestation villi, 14 cases of hydatidiform mole, 12 cases of invasive hydatidiform mole and 12 cases of choriocarcinoma were detected by immunohistochemistry test.

采用免疫组化SP法检测14例正常早孕绒毛、14例葡萄胎、12例侵蚀性葡萄胎及12例绒癌滋养细胞中survivin的表达。

Objective This study was conducted to detect the expression of laminin and laminin receptor in the specimens of hydatidiform mole, invasive mole and choriocarcinoma, respectively.

目的 了解葡萄胎、侵蚀性葡萄胎和绒毛膜癌组织中层粘连蛋白及其受体的表达，并探讨LN、LN-R与妊娠滋养细胞肿瘤侵袭和转移的关系。

Results Stain for EGFR was detected in all cell types of trophoblasts in GTD and normal chorion villi.

目的 研究表皮生长因子受体在妊娠滋养细胞疾病的表达，探讨EGFR对预测葡萄胎恶变的价值。

In syncytiotrophoblasts,expression of EGFR protein were strong in GTD tissues and normal chorion villi,and there was no significant differences observed among them.

EGFR表达降低在妊娠滋养细胞疾病发生发展过程中起重要作用，并有可能成为预测葡萄胎恶变的一项新的指标。

In syncytiotrophoblasts,expression of EGFR protein were strong in GTD and normal chorion villi,and no significant differences were observed among them.

EGFR表达降低在妊娠滋养细胞疾病发生发展过程中起重要作用并有可能成为预测葡萄胎恶变的一项新的指标。

Methods 105 cases of GTD tissues and 20 cases of normal chorion villi specimens were examined by immunohistochemical techniques using EGFR monoclonal antibody.

采用免疫组化方法，检测石蜡包埋的105例妊娠滋养细胞肿瘤组织和20例正常早孕绒毛组织EGFR蛋白表达水平。

In normal pregnancy, trophocyte secrete varies hormones, besides hCG, it participate in synthesis of steroid hormones, hPL and so on. JAR cell posses the function of secretion such hormones.

三、正常妊娠时滋养细胞分泌多种激素，除了hCG以外尚参与了类固醇激素，hPL等多种激素的合成与分泌，JAR细胞也具有分泌这些激素的功能。

Results: The positive unit of survivin expression intensity in trophocyte cytoplasm and karyon was subsequently increased in following order: normal early gestation villi, hydatidiform mole, invasive hydatidiform mole and choriocarcinoma.

结果：survivin在滋养细胞细胞核及细胞浆的表达强度PU值依下列顺序增加：正常早孕组、葡萄胎组、侵蚀性葡萄胎组及绒癌组，各组间的表达强度差异有统计学意义(P.05)。

Specific pigmenting of VEGF was mainly in trophoblast, next in decidua and endothelial cell of capillary, the positive cell also could be observed in stroma.

提示妊娠过程中VEGF、PLGF表达下降能影响血管内皮细胞和滋养细胞的功能，与子痫前期、子痫的发生发展有关。3、随着病情的加重，VEGF、PLGF表达逐渐下降。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
