早期收缩

By inhibiting vasoconstriction, the use of low-dose aspirin in the first trimester could influence placentation and therefore prevent or delay development of hypertensive pregnancy complications, such as pregnancy-induced hypertension and pre-eclampsia.

在妊娠早期的三个月使用低剂量阿司匹林可以作用于胎盘，通过抑制胎盘血管收缩从而防止或推迟妊娠高血压并发症的发展，如妊娠高血压综合征和先兆子痫。

Admixing vegetable fibers into concrete can reduce the plastic constraint crack at early age and improve its crack resistance performance greatly.

It provided the reference to improve the anti-cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement.The result shows that the more the binder material or sand rate, the more serious the shrinkage cracking. In the concrete with a low water-to-binder ratio, a bit of difference in the dosage of water will result in big difference on the strength and the anti-cracking capability. The occurrence of cracking is mainly at early age (before 1 day). If the surface is plastered again after 2 hours of casting, the anti-cracking capability will nicely improved.

研究结果表明：随着胶结料总量和砂率的增大，高强高性能混凝土的收缩开裂趋于严重；在水胶比较低的情况下，用水量的稍微差别对混凝土的强度和抗裂性能都具有很大的影响；掺入粉煤灰对抗裂有所改善，但是其掺量对抗裂的影响并不是呈定向规律，而是存在着最优掺量；高强高性能混凝土的裂缝主要发生在早期(1d前)，若在浇注后2个小时再次抹面可以很好地改善其抗裂性能。

The basin is one of the Cenozoic rift basins, which has experienced a series of paleo-climate change since Early Pleistocene, including wet cold, wet-warm, and arid. A former lake was believed to develop at the early stage of late Pleistocene (around 120 ka BP), and vanish during the Holocene. With the vanishment of the lake, the early Yellow River occurred. It results in a complex sedimentary environment with fluvial and lacustrine sediments interlacing each other.

河套盆地是一个新生代断陷盆地，自更新世早期以来经历了由湿冷-湿冷/暖-全新世干旱的古气候变化，盆地的发展经历了湖泊全盛期-收缩期-消亡期-河流发育期，沉积环境演化为湖积/河积交错沉积。

It will be demonstrated that these methods are able to monitor bronchoconstriction in safety-pharmacological tests or in asthma models showing early allergic response or late airway hyperresponsieness in response to inhaled allergens and demonstrate drug effects on pulmonary endpoints.

这些方法在安全药理学实验中可以监测支气管的收缩性，在吸入变应原的哮喘模型中可以显示早期的过敏反应和晚期的气道高反应性，并可以监测药物对肺功能的最终影响。

被诱导的心肌细胞的判定除常规指标外，我们还用了心脏特异性引物β-MHC对不同收缩时间的心肌细胞总RNA进行RT-PCR扩增和RNA斑点杂交，发现该心肌细胞不仅具有正常心肌细胞的特性，而且在分化早期就高度地表达心脏特异性基因。
