激发因子

Juvenile bronchial asthma is a severe disease which is harmful to children. It characterized of whoop , dyspnea , chest stuffiness and cough time after time. It is caused by the EOS, T-cell and so on which lead the chronic inflammation of respiratory air-way. Asthma often outbreak or aggravate at nighttime and early morning.

支气管哮喘简称哮喘，是由嗜酸性粒细胞、肥大细胞和T淋巴细胞等多种炎性细胞参与的气道慢性炎症，使易感者对各种激发因子具有气道高反应性，并可引起气道缩窄，表现为反复发作的喘息、呼吸困难、胸闷或咳嗽等症状，常在夜间和清晨发作、加剧，多数患儿可经治疗或自行缓解。

One hand mechanical obstruct led to the increase of veinous resistance and the obstacle of microcirculation, the other hand the adhesive PMN was activated in excess, the white blood cells released a lot of enzymes, in which PMN-elastase can decompose the components of cell and many albumens, inclusive of immunoglobulin、alexin and fibrication. These components induced the injury of the pancreatic capillary vessels and cell and lysosome enzy made the tissue protein hydrolyze and produced unsaturated fatty acids, which destroyed the structure and function of cellar membrane. The inflammatory cellar factors activate other immunocytes to produce the injury and necrosis of tissue, which aggravated the pathological injury and led to shock、pyaemia and MODS. So ICAM-1 and LFA-1 played an important role in SAP. Frossard found that the expression of ICAM-1 in the rat model, especially in serum、pancreas and lung. All these showed ICAM-1 is an important factor in AP and concomitant lung injury.

胰腺小叶组织局部血管EC首先被激活，ICAM-1表达升高，与被激活的PMN表面表达的LFA-1相结合，"PMN-EC"相互作用加剧，一方面机械性阻塞毛细血管导致静脉阻力增加、微循环障碍；另一方面粘附的PMN过度吞噬或激活，当白细胞吞噬的颗粒不能被封闭隔离，连同细胞内的酶被释放出来，其中的PMN-elastase能够降解细胞基质中各种成分，水解多种蛋白，加重胰腺的毛细血管内皮细胞和腺泡的损伤；释放的溶酶体酶使组织蛋白水解，产生的不饱和脂肪酸引发脂质过氧化方应，破坏细胞膜的结构和功能；释放的炎性细胞因子，激发其他的免疫细胞的功能，导致进一步的组织损伤和坏死，加重SAP的病理损伤，最终导致休克、脓毒血症及多器官功能障碍等严重后果。

We performed a field experiment by the end of 2004, and based on the data of this experiment, we studied the amplitude degression and corresponding seismic attenuation factor of both single event waveform and cross-correlation function. It is found that, same as single event waveform, cross-correlation function could be used to assess the seismic attenuation.

依据野外现场实验的数据，我们分别以单次和多次激发为源，讨论了事件波形和互相关函数波形的振幅变化及相应的介质品质因子，结果发现，与事件波形一样，互相关函数波形也可以用于计算介质的衰减系数。

The GTPase activating protein played an important role during the growth and development period of chickling as a type of activating factor.

2初步认为GTPase激活蛋白作为一种激发因子，在雏鸡的生长发育过程中具有重要作用。

The relations between quality factor and the periods of air holes around the defect and the thickness of slab are demonstrated.Then, the positions and shapes of nearest holes are adjusted to excite more defect modes, and the relation between defect modes and modified cavity in defect region are discussed. Moreover, the mechanism of light confinement in vertical and plane direction is discussed, and how they effect the quality factor can be induced.

先探讨结构周期数和厚度对品质因子的影响，接著修正缺陷空腔附近空气柱大小和位置，分析其与激发模态的关系，及相应品质因子的大小，此外分别讨论垂直方向和平面方向的光局限机制与影响品质因子的程度。

An intrinsic goal is a motivating factor that is inside you, instead of outside of you.

内在的追求目标是一种人体内的激发因子，并不体现在外。

推测其作用机制可能有以下几个方面：(1)研究证实，在EAE的发生和发展中，有多种炎性细胞因子，如白细胞介素-1、2，肿瘤坏死因子a和干扰素g发挥着重要作用，他们的存在进一步激发了HO-1的表达[17]。
