The results showed that steroid potentiates hypercoagulable and hypofibrinolytic states which would play an important role in inducing and developing osteonecrosis, these might cause IC, forming intraosseous thrombi, which would further cause ischemia of bone marrow and bone, thus result in osteonecrosis.

这表明激素助长了高凝和纤溶下降状态，高凝和纤溶下降在激素性骨坏死发生发展中起重要作用，二者异常引起骨内IC，形成骨内血栓，引起骨缺血乃至骨坏死。

For the first time, we found that the EHFV propagated in HUVEC has a potentiating stimulation to ET-1 and PGI〓 secretion , which may be respensible for the increased plasma ET -1 level and PGI〓 concentration in patients with EHF during the early phase of the disease.

我们的研究结果提示，HUVEC对EHFV敏感，EHFV感染未引起HUVEC的细胞病变，但可抑制HUVEC的增殖，这有可能改变EC的基因调节，或低调，如Ⅷ R：Ag合成障碍，引起止血功能异常；或高调，如主要组织相容性复合物Ⅱ型抗原、干扰素β和内皮细胞白细胞粘附因子的表达增加，增强EC的炎症反应。

Our results indicated that (1)SO_2 derivatives could dose-dependently relax the isolated aorta rings with or without endothelium precontracted by NE, no difference was found for the rings with and without endothelium;(2)Levels of cAMP and 6-Keto(PGI_2) in isolated aortic rings were increased by SO_2 derivatives in a dose-dependent way, which were independent of endothelium;(3)SO_2 derivatives decreased cGMP levels in the rings, but not significantly; The decrease of cGMP levels was also independent of endothelium;(4)No changes of TXB_2 in rings with or without endothelium were observed;(5)Whether presence or absence of endothelium, cAMP/cGMP and 6-Keto/TXB_2 ratios were increased significantly.

结果：①SO_2衍生物对去甲肾上腺素预收缩的内皮完整和去除内皮的大鼠胸主动脉血管环均呈浓度依赖性舒张作用，且其张力变化在内皮完整与去内皮的血管环之间无显著性差异；②SO_2衍生物可引起血管组织中cAMP、6-Keto(即PGI_2)含量剂量依赖性增加，其增加程度与内皮无关；③SO_2衍生物对血管环cGMP含量呈降低趋势但在统计学上无显著意义，且对去除内皮血管无显著影响；④SO_2衍生物对去内皮或内皮完整血管环的TXB_2含量均无明显影响；⑤无论是否去除内皮，SO_2衍生物均可引起cAMP／cGMP和6-Keto／TXB_2比值显著升高。

This will not only cause long-time shutdown, but also cause some unstable factors during the period of readdressing.

这不仅会引起长时间的停机，而且还会在重新编址阶段引起不稳定。

In all of these glazes, Rayleigh scatting contributes to the blue color, but in Ru ware, Rayleigh scattering intensity is weaker than in Ru modern copies and Jun ware, and Mie scattering intensity is stronger than in Ru modern copies and Jun ware.

汝瓷、仿汝瓷和钧瓷釉中的蓝色均有Rayleigh散射的贡献，其中汝瓷中的Rayleigh散射强度小于仿汝瓷和钧瓷；而对于釉中的乳白色感，汝瓷中是由大量析晶及&晶芽&引起的，而仿汝瓷、钧瓷是由少量分相大颗粒引起。

Under the circumstance of high temperature and high rotating speed, the influence of orientation lessens a lot because the structure softens with the decrease of elastic modulus and stiffens with the centrifugal force.

在高温高速旋转工作状态，因弹性模量下降引起的结构软化和离心力作用引起的结构刚度加强，使晶向的影响大大减弱。

In the process of immigration of eastern Sichuan and western Hubei, at least three issues are worthy of noting: one, the settlers had a difficult trip, life was unstable and crafts was extremely difficult in the mountain region in early time; two, Land disputes are more common in initial time of immigration, occupying boundary, subleasing, reselling and looting land often caused fights even murder, which shows early highly complex relation of immigration in community; three, immigrants plays a very important role in the development of local economy. If the local economic development can be divided into four stages, the fourth period (that is, from the middle of the 18th century to the 19th century) is the most important period for immigration, is the period of fastest development of economy and is the period of the local economic development the largest impacted by immigrants.

初期移民社会至少有三个问题引起本文注意，首先、移民们行程艰难，到达深山地区初期的生活很不稳定，劳作极其艰辛；其次、土地纠纷是初期移民社会较为普遍的现象，蒙混占界、转租转卖、抢占土地往往引起群殴甚至酿成命案，初期移民社会围绕土地争夺而展开的各种关系极为复杂；三、移民给当地社会经济带来了较大的变化，如果可以将唐宋至十九世纪末当地经济的发展分为四个时期，那么，第三个时期(即十八世纪中叶到十九世纪)是移民的重要时期也是当地经济发展最快的时期，移民对经济发展变化的影响是很大的。

Voltage sags may be caused by faults on the transmission or distribution system, or by the switching of loads with large amounts of initial tarting\inrush currents (motors, transformers, large DC power supplies).

电压下跌可由输配电系统中的故障引起，或由投切具有大初始起动电流；涌流(电动机，变压器，大型直流电源)的负荷引起。

The less of E-cadherin in leukemia cells may result in β-catenin translocating to the nu-clear and transcriptional activation of its target genes.

白血病细胞中E-cadherin表达降低或缺失可引起β'-catenin从细胞膜释放并进入细胞核，最终可能会引起β-catenin靶基因的转录。

The cry he gave was echoed, not only by his companions on board, but by a great number of voices from the shore, and looking in that direction I saw the other pirates trooping out from among the trees and tumbling into their places in the boats.

那人发出的惨叫声不仅在他船上的同伙中引起了反响，也在岸上引起了一阵喧哗。我朝岸上望去，看到其他海盗正纷纷从树林里跑出来，慌慌张张地爬进他们的小船。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.
