In this double-blind study, 142 women with high-risk singleton pregnancies received 100 mg progesterone or placebo daily by vaginal suppository. Between 24 and 34 weeks of gestation, all subjects had uterine contraction monitoring with an external tocodynamometer once weekly for 60 minutes.

对早产的高危险孕妇来说，预防性地在阴道使用progesterone可降低子宫收缩的频率，并减少早产的发生，虽然目前我们还不清楚它的作用机转为何，但我们知道它对子宫肌肉层有2种作用：一为藉由抑制细胞质内动情素受体的取代而抑制动情素发挥作用，另一个则是经由它自身的细胞性受体而直接作用在子宫的生合成路径上。

The facile N-participated transannular reductive rearrangement supports the postulated biogenesis of CET, and accordingly the current synthesis might be regarded as a biomimetic synthesis.

第三章记述了我们在三尖杉碱合成的基础上，应用跨环Clemmensen还原重排关键步骤，成功地构筑了百部碱5-6-7三环核心骨架的研究。

C8051F005 is the control center of the survey meter, the signal is obtained by jaw pressure transformator and current transformator. Direct Digital Frequency Synthetics technology is adopted to automatically adjust the frequency of the actuating signal and avoid the interference of the signal in the ground network.

该检测仪采用C8051F005单片机作为控制处理中心，钳口式电压互感器和电流互感器检测接地电阻信号，运用直接数字频率合成技术自动调整激励信号频率，从而避免地网中干扰信号源的影响。

These data demonstrated that tributyrin can efficiently inhibit gastric cancer cell growth by inhibiting DNA synthesis and inducing apoptosis. The tributyrin-induced apoptosis is associated with down-regulation of Bcl-2 expression and up-regulation of Bax expression.

这些结果首次显示tributyrin能有效地通过抑制DNA合成和诱导细胞凋亡达到抑制胃癌细胞生长的作用，细胞凋亡与Bcl-2表达量下调和Bax表达量上升有关。

In addition, the four-armed macrocyclic guest forms a complex with molecular cage, in which each of the limbs of the guest protrudes from a unique macrocyclic face of the host to result in a turtlelike supramolecular complex.

我们亦成功地合成具有四突出取代基的小环分子并以之与笼状冠醚分子错合形成独特的类&乌龟&形的超分子错合体。

By following the "self-assisted molecular editing" protocol first established in our labs,a number of Aphos ligands were efficiently prepared from a single starting material and they were screened for catalytic efficacy, leading to the discovery of the best-performing Aphos appended with a 3-nitrophenyl group at the C4 position.Combination of this Aphos with Pd_2 offers a precatalyst for successful cross-coupling of unactivated aryl chlorides with aryl boronic acids at room temperature.The reactions took place under mild basic conditions to produce the products in high yields.

通过我们首次提出的&自助分子剪裁&的概念从单一起始物快速合成和筛选了一系列膦配体，并发现C4位含3-硝基苯基的的膦配体和醋酸钯联用可以在室温下顺利地催化不活泼氯代芳烃和芳基硼酸的偶联反应，反应条件温和且产物收率很高。
