胎盘的

Objective:to investigate the cesarean section of the reasons for the bleeding, and lower the rate of obstetric hysterectomy possibility.methods: 30 cases in our hospital cesarean section in the clinical data of patients with hemorrhage were retrospectively analyzed.results: in 30 cases of bleeding, placental factors accounted for 53.33%, 36.67% of the uterine atony, uterine incision bleeding laceration of 6.67%, 3.33% of the amniotic fluid embolism, hysterectomy three cases.conclusion:placenta, uterine atony cesarean section is the main reason for the bleeding.

目的：探讨剖宫产术中大出血的原因及降低产科子宫切除率的可能性。方法：对我院30例剖宫产术中大出血患者的临床资料进行回顾性分析。结果：30例大出血中，胎盘因素占53.33%，宫缩乏力占36.67%，子宫切口裂伤出血占6.67%，羊水栓塞占3.33%。治疗结果中，子宫切除3例，占剖宫产术的0.076%（3/3 935）。结论：胎盘因素、宫缩乏力是剖宫产术中大出血的主要原因。

Representation of the world, mainly in the placental extract, Switzerland and Japan Placenta with a high purity, high-quality and high security features, extracted from the cells, the completion of injection can be divided into three stages: First, using the most advanced chemical and biological equipment, from the sheep embryo to extract the liver activity of the protein to remove impurities, heat-sensitive protein and can cause allergic reactions of the various types of risk factors, followed by the adoption of advanced technology on the extraction of viable cells were isolated, and thus be the activity of cells with different efficacy, such as the thymus cells, placental cells, liver cells and so on dozens of different types, the final freeze-dried using the most advanced technology to help keep cells alive nature.

胎盘素具有高纯度、高品质和高安全性的特点，从细胞的提取到针剂的完成可分为三个阶段：首先运用最先进的生化仪器，从小羊胚胎的肝脏中提取活性蛋白质去除杂质、热敏感蛋白质及可能导致过敏反应的各类危险因子，其次通过先进的技术对提取的活性细胞进行分离，从而得到具有不同功效的活性细胞，如胸腺细胞、胎盘细胞、肝脏细胞等几十种不同类型，最后采用目前最先进的冻干技术来保持细胞鲜活性。

Glucose has obvious protection from the hot stability of the deer placenta polypeptide, The denaturation rate of the deer placenta polypeptide reduces 40.11%, the antioxygenic property enhances 34.19% when it is heated under 60℃ for 30min with glucose's joining.

葡萄糖对鹿胎盘多肽的热稳定性有明显的保护作用，它使鹿胎盘多肽在60℃的条件下加热30min 后的变性率降低了40.11%，抗氧化性提高了34.19%。

Leptin is a hormone that regulates metabolic efficiency,energy expenditure.It is mainly produced in adipose.Now we acknowlege that leptin is also present in placenta.It can mediate the excretory function of cytotrophoblast and vascular growth. Leptin participates in pregnancy complication.

瘦素是由肥胖基因编码的调节能量代谢的物质，主要由脂肪细胞合成，现已证实胎盘也合成瘦素，可调节滋养细胞的分泌功能及胎盘血管的生成，与生殖及PIH等疾病密切相关。

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。

That because dyoxygen induced trophocyte proliferation and hCG secretion, at that moment, hPL level is not high, which is consistent with hPL level in placenta dysfunction, What this study show that hCG increase being not promote hPL secretion significantly may explain the phenomenon.

而在一些妊娠晚期子宫胎盘局部缺氧的病例，往往表现为hCG水平高于正常相同孕周妊娠者，这是因为缺氧诱发了滋养细胞的增生，hCG大量分泌，但此时hPL水平不高，是与胎盘功能不良时hPL水平往往不高相一致，本研究结果显示的hCG增高并不明显促进hPL的分泌可能可以解释这一现象。

The over-all increase is not due to the velocity constant of the placental transfer but to changes in the relationship of the placental and foetal tissue.

这种增加不是由于胎盘转化速度的持续引起的，而是源自于胎盘和胎儿组织的关系转化。

Disease history and induced factor should be gaid attention in early diagnosis of the disease ultrasound B is an important auxiliary diagnosis method for the disease.timely ceasing pregnancy can reduce the severe complication of mother and child.??

胎盘早剥的早期诊断更应注重病史及诱因，B超已成为胎盘早剥的重要辅助诊断方法。适时终止妊娠可减少母子严重的并发症。？？

Among these, the most prevalent was endosulfan-diol, with an average concentration of 4.15 nanograms per gram of placenta.

在这些中最普遍的是二醇硫丹，它的平均浓度为每克胎盘组织中富集4.15毫微克，令人惊讶的是，668例孕妇样本中，一些患者的胎盘中甚至含有15～17 种杀虫剂。

We also use rank sum test to analyse the differe- nce between the light pre-eclampsia group and the severe pre-eclampsia group (P=0.000),the early onset pre-eclampsia group and the late onset pre-eclampsia group (P=0.003). All of the results give the same conclude that the differences within the three groups are significant (P.05). Conclusion: We conclude that HLA-G proteins are normally expressed in invasive trophoblasts and HLA-G proteins expression is defective in most pre-eclamptic placenta.We propose that trophoblasts lacking HLA-G proteins are vulnerable to attack by the maternal immune system.

结论HLA-G分子特异性分布于胎盘EVCT的胞膜及胞浆中，生理妊娠组、子痫前期组间差异性存在表明其表达量的下降与子痫前期的发病相关；轻、重度子痫前期组间显著差异表明HLA-G分子表达量的下降与子痫前期病情严重程度相关，早发型重度子痫前期患者胎盘组织中HLA-G分子的表达明显低于迟发型组，提示我们HLA-G分子表达的降低程度还与发病早晚有关。

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。
