胎盘

Objective To study the clinicopathologic features and differential diagnosis of placental site trophoblastic tumor.

目的 了解胎盘部位滋养细胞肿瘤的临床病理特点及其鉴别诊断要点。

From this study, both low hCG and high hCG are adversity to pregnancy, hCG level reflect the growth and function situation of trophocyte which is the main component of placenta, whereas, the level of steroid hormone which close to hCG directly influence whether pregnancy will maintain, but in some cases being short of oxygen in uterine placenta local, usually display hCG level higher than normal pregnancy.

在正常妊娠时hCG过低往往预示着流产的可能，从本研究结果看，可能不仅仅是hCG水平过低对妊娠不利，hCG水平很高对妊娠也不利。hCG水平的高低反映了作为胎盘主要组份的滋养细胞的生长情况与功能，而与hCG水平高低密切相关的类固醇激素的高低直接影响了妊娠能否持续下去。

The activation of endothelial cell caused by TNF-α has detrimental effects on the vasculature. TNF-α can induce the increased apoptosis of gravid trophocyte. TNF-α has been showing up-regulate the vasoconstriction factors such as endothelin and down-regulate the vascular relaxing factors such as NO on the contrary.

肿瘤坏死因子α作为炎性分子，激活血管内皮细胞、间接影响血管舒缩功能，通过各种机制诱导胎盘滋养细胞凋亡增加，增加血管收缩因子并减少血管舒张因子的生成和释放，影响与脂类代谢相关的细胞因子。

Supersonic examination is the only accurate unwounded check method in evaluation in clinicial emergency treatment.

超声检查是唯一评估胎盘早剥的定性准确的无创检查方法，对于临床急诊救治有重要意义。

Supersonic examination is the only accurate unwounded check method in evaluation in clinicial emergency treatment.

超声检查是唯评估胎盘早剥的定性准确的无创检查方法，对于临床急诊救治有重要意义。

Though uteroplacental apoplexy is a severely danger to perinatal fetus,active measure can avoid death of pregnant woman and save uterine.

子宫胎盘卒中严重威胁围产儿的生命，但积极救治，可避免孕产妇的死亡，并可以保留子宫。

Uteroplacental apoplexy can't be seen totally as the indication of hysterectomy, but should apply bilateral ligation of the ascendant branch of uterine arteries or pack the womb with iodoform gauze strip first.

重型胎盘早剥早诊断，不能短时间分娩者，立即行剖宫产，尽早应用冷沉淀及输血，子宫卒中可先采用双侧子宫动脉上行支结扎术或碘仿纱条填塞子宫，而不能完全成为子宫切除指征。

The expression levels of Cx genes were compatible with the differenciation and development of placental villous cells.

探索妊娠不同时期人胎盘绒毛细胞连接蛋白基因表达的规律及其与细胞分化的关系。

Chorionic villous sampling: In this procedure a biopsy from the placenta is taken to test the fetus' genetic make-up.

绒毛膜绒毛取样的：在这个从胎盘活检采取测试胎儿的基因组成的程序。

The distribution of MDR3 and BSEP in ICP group is similar to that of placenta of normal group. They are all found in villous syncytiotrophoblast.

结果在ICP组胎盘组织中检测到MDR3、BSEP及FIC1三种基因mRNA和MDR3蛋白、BSEP蛋白的表达。
