胎盘

Regression of the decidualized mesometrium and decidual cell apoptosis are associated with a shift in expression of Bcl2 family members.

因此， 胎盘CT中p53的表达可能参与控制过量的细胞增殖，以保证胎盘这一重要器官发育和分化的动态平衡。

Dizygotic twins, like any other siblings, have an extremely small chance of having the exact same chromosome profile.

严谨地讲，因为是不同胎盘而是认为是异卵双胞胎，这个论断已经靠不住了，因为如下文所示，有20-30%的可能性同卵双胞胎有独立的胎盘。

Placenta as a key temporary organ for maintaining oxygen and nutritive substance exchange in universe and foetus contained immature embryon and adult stem cells that trended to maturity no matter from anatomic structure or growth, besides, placenta could not be related to ethics.

胎盘作为胚胎发育中维系母体和胎儿氧气及营养物质交换的重要暂时性器官，无论从解剖结构还是在发育行为上，都包含了较为幼稚的胚胎及趋于成熟的成体干细胞成分，而且胎盘不会涉及伦理道德问题，目前已成为寻找人类间充质干细胞新来源及提高临床应用效果的研究热点。

Part 1: Permeability of Exogenetic BDNF through placental barrier of pregnant rats and blood-brain barrier of fetus with transient uteroplacental ischemiaObjective To investigate the potential of BDNF to penetrate the placental barrier and get into the fetus and pass through the blood-brain barrier of fetus to play neuroprotective function in the condition of transient ischemia.

第一部分：外源性脑源性神经营养因子在宫内缺氧环境中对胎盘及胚鼠血脑屏障通透性的实验研究目的：探讨外源性脑源性神经营养因子在宫内缺氧环境下能否通过胎盘屏障进入胎鼠体内，再通过胎鼠血脑屏障进入胎鼠脑组织而发挥其生物功能。

We have performed systematical studies on intrauterine transmission of hepatitis B virus and our studies suggested that HBV may occur through progressive infection of different placental layers until the virus reaches the fetoplacental circulation, which is the named "transplacental cellular traffic" except through placental tears with transfusion of infected maternal blood into the fetal circulation, which is the named "hematogenous transmission".

我室近年来对HBV宫内传播进行了系列研究，发现了胎盘在宫内传播中的作用，并提出了HBV宫内传播机制的假设：除血源性途径外，还可通过HBV在胎盘组织内的&细胞传递&途径，即HBV可以从母体蜕膜细胞通过&逐层转移&至胎儿绒毛毛细血管内皮细胞，导致胎儿感染。

Objective To evaluate the ultrasonographic features of intervillous circulation in normal early pregnancies and early inevitable abortions,and to assess the value of grey-scale ultrasound and color power Doppler in the examination of intervillous circulation in early inevitable abortions.

目的探讨正常与异常早孕胎盘结构及绒毛间隙血流循环的超声特征，评价灰阶和彩色能量多普勒超声在早期难免流产胎盘诊断中的价值。

The moving echoes and local hypoechoic areas in the intervillous space before 10 weeks of gestation is important ultrasonographic features of early inevitable abortions.

结论胎盘绒毛间隙弥漫移动点状回声和胎盘中央低回声区是孕10周前早期难免流产的重要超声表现。

HBV transplacental transmission route may be realized by cell to cell transfer in placenta, which means that HBVs in maternal blood and/or intervillous space infect DCEC and/or DC and/or TC, then transmit to VMC, then to VCEC, and finally to fetus.

HBV经胎盘感染胎儿的路径可能是通过胎盘细胞至细胞的传递而实现的。即母血和/或绒毛间隙HBV→蜕膜毛细胞管内皮细胞和/或蜕膜细胞和/或滋养层细胞→绒毛间质细胞→绒毛毛细血管内皮细胞→胎儿。

Results:Significant differences were found in strictured intervillous spaces of the placentae in ICP(P.05).Conclusion:Strictured intervillous space of the placentae in ICP is an important cause for acute hypoxia in the ute...

提示 ：ICP胎盘绒毛间隙狭窄是围产儿宫内缺氧、病死率增加的重要原因，因此，重视预防和积极处理妊娠胆汁淤积症，改善胎盘功能，对降低围产儿死亡率，提高优生率有重要意义

AIM: To investigate the effects of goat placenta immunoregulating factor on the expression of costimulatory molecules lineaged T cells in BALB/c mice. METHODS: Animal model for immunodeficiency made from BALB/c mice with whole-body irradiation by 5 Gy 60Coγ-ray was applied for research.

目的：分析羊胎盘免疫调节因子对BALB/c小鼠T淋巴细胞共刺激表面抗原分子表达及其细胞因子分泌的影响，探讨羊胎盘免疫调节因子免疫促进作用机理。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
