Research of microenvironment werefocused on the neurotrophic factors. Many studies have been done to use nerve conduits filled with exogenetic NTFs with the intention of promote axonal regeneration to the greatest extent efficiently. However concentration of exogenetic NTFs and the means of releasing NTFs still need to be studied.

对于后者，研究主要集中在神经营养因子(neurotrophic factors，NTFs)，众多学者尝试将外源性NTFs引入神经导管，以期尽可能有效地促进轴突再生，但外源性NTFs导入的浓度和释放的途径仍需进一步研究，同时最有益于神经再生所必须的营养因子的数量和种类也待进一步明确。

Recently, a new pluripotent stem cell establishing method was reported that, mouse and human differentiated cells could be induced reprogrammed into a pluripotent state by expressing exogenetic stem factors such as Oct4, Sox2, et al, through retroviral transduction.

通过反转录病毒载体系统，在小鼠和人类高度分化细胞中表达干细胞因子Oct4， Sox2， Klf4和/或c-Myc等基因，再经过干细胞标志因子Nanog或Oct4筛选，可以获得与ES细胞特性十分近似的诱导多能干细胞系。

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。

This experiment is to investigate the effect of IL-10 on bleomycin-induced pulmonary fibrosis in rats by administrating exogenic IL-10 at its different stages .

而IL-10作为一种强大的细胞因子调节因子在肺纤维化中的作用尚不明了。

PART 2:The molecular mechanisms of Nontypeable Haemophilus influenzae induced inflammatory response in respiratory epithelial cells Objective:Nontypeable Haemophilus influenzaewas traditionally considered as an extracellular pathogen in respiratory infections.In this study,we established a model of infected cells to confirm NTHI was also a facultatively intracellular pathogen.Mitogen activated protein kinasesare the important signal transduction pathway in mediating inflammatory response induced by NTHI in respiratory epithelium.In this study,we elucidate the impact of NTHI,and its SCF and EP on the expression of MAPK and subsequent proinflammatory mediators.

第二部分：NTHI致呼吸道上皮细胞炎症反应的分子机制研究目的：通过建立呼吸道上皮细胞株的体外NTHI感染模型，确认NTHI在细胞内的存活，观察NTHI及其组分(可溶性胞质成分SCF、外膜蛋白EP)对呼吸道上皮细胞MAPK信号传导通路和后续的前炎症因子表达的影响，并应用特异性ERK-MAPK抑制剂U0126、p38 MAPK抑制剂SB203580特异性阻断下游MAPK信号传导通路，观察它们对呼吸道上皮细胞分泌前炎症因子表达的影响。

PGE2 may serve as a vasodilator of the fetoplacental circulation.

那么PGE2 是胎儿胎盘循环的扩张因子还是收缩因子？

LT and ST are the main enterotoxins of enterotoxigenic \$Escherichia coli \$found in clinical isolates, and CS3 (the common antigen in the CFA/Ⅱ family of fimbrial antigens) is one of the most prevalent antigens of colonization factors.

不耐热肠毒素和耐热肠毒素是产肠毒素大肠杆菌的主要致病因素，CS3为该菌的优势定居因子，是定居因子CFA/II菌毛抗原的共有抗原组分。

This thesis formulize geology disaster system's character-complexity relevance、self-organization、fractal and catastrophe. Affecting factor-rainfall of the best of relevance grade is concluded in the use of grey relevance analysis and It provides reference of geology disaster prediction.

作者以系统的观点，分析阐述了合阳县地质灾害系统特性，即复杂关联性、自组织性、分形分维及突变性，并利用灰色关联分析，确定出合阳县地质灾害系统中最大关联度的影响因子—降雨因子，这为合阳县地质灾害的预警提供参考了依据。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
