免疫系统

MG is the result of a selective overactivity of the body's immune system in which patients produce antibodies against a particular target in their own body.

MG是由机体免疫系统产生的一种选择性亢奋引起的。机体免疫系统是发病者对于内特殊靶群产生抗体的组织。好像不对，自己都看不懂，可能是因为不是学医的，很多名词都不知道。呜呜呜。

"One of the complications of antibiotic therapy is secondary infection," Weiser explains."This is a huge problem in hospitals, but there hasn't been a mechanistic understanding of how that occurs. We suggest that if the immune system is on idle, and you treat someone with broad-spectrum antibiotics, then you turn the system off. The system is deprimed and will be less efficient at responding quickly to new infections."

"抗生素治疗的一个主要并发症就是继发感染"，Weiser教授这样解释到，这是医院内的一个重大问题，但是现在的机制还不是很清楚，我们假设免疫系统是一辆汽车，已经使它蓄势待发，这时，广谱的抗生素治疗相当于釜底抽薪，对于新的感染，免疫系统就不那么灵敏，不那么有效了。

The herpes viruses spur the immune system to boost levels of a protein hormone called interferon gamma "that in effect puts some immune system soldiers on yellow alert, causing them to patrol for invaders with their eyes wide open and defense weapons ready," Virgin said.

疱疹病毒刺激免疫系统使一种称为干扰素γ的蛋白质激素的水平提高，"那实际上就是向免疫系统士兵拉响空袭警报，唤起他们睁大眼睛和准备好防御武器去巡视侵入者，"Virgin说道。

The herpes iruses spur the immune system to boost leels of a protein hormone called interferon gamma "that in effect puts some immune system soldiers on yellow alert, causing them to patrol for inaders with their eyes wide open and defense weapons ready," irgin said.

疱疹病毒刺激免疫系统使一种称为干扰素γ的蛋白质激素的水平提高，"那实际上就是向免疫系统士兵拉响空袭警报，唤起他们睁大眼睛和准备好防御武器去巡视侵入者，"irgin说道。

David Elliott, a gastroenterologist and immunologist at the University of Iowa, indicate that intestinal worms, which have been all but eliminated in developed countries, are "likely to be the biggest player" in regulating the immune system to respond appropriately, Dr.

艾略奥特博士的研究表明，已在发达国家全部消除的肠道寄生虫，对调节免疫系统作出适当反应&可能是起最大作用的&，艾略奥特博士在一次采访时说道，细菌感染和病毒感染似乎以同样的方式影响着免疫系统，但力度不同。

Viral vector mainly contain adenovirus, retrovirus,adeno-associated virus and so on, but it has potential danger of safety; it isrepeled by immune system when it is injected to organism for a greatimmunogenicity. An injection with adenovirus vector with highconcentration, it leads to serious inflammatory reaction of liver. Viralvector such as liposome and polycation are commonly used lately. But,liposome and polycation have low specificness and targetness of genetransfer tissue, have lower transfection efficiency and short period ofgene expression, for they can be phagocytized by endothelial system.

许多的载体，病毒载体和非病毒载体以前已广泛应用，病毒载体主要包括腺病毒，逆转录病毒，腺相关病毒等；但病毒载体在安全性方面存在潜在的危险；免疫原性比较强，注射到机体后很快会被机体的免疫系统排斥，当静脉注射高浓度的腺病毒载体会使肝脏发生严重的炎症反应；非病毒载体目前常用的有脂质体及多聚阳离子聚合物；但脂质体和阳离子聚合物介导基因转移缺乏组织的特异性和靶向性，转染效率较低且易被网状内皮系统吞噬，基因表达时间短；因此研制新型的非病毒载体已成为研究的热点，纳米颗粒具有小尺寸效应，表面效应，随着颗粒直径变小，比表面积将会显著增大，故具有很高的化学活性，因而纳米成为了最有应用前景的非病毒载体。

Otherwise,sugar maybe destory the immune system,induce the lack of nutrition elements as magnesium,chromium and zincum thereby cause man suffer cold with easy and other diseases related to the immune system.

糖份还会破坏免疫系统，引起镁、铬和锌等营养素的缺乏，使人容易患上感冒和其他与免疫系统有关的疾病。

Give the immune system a break from that life-or-death battle, and it might be better able to do the surveillance work of corralling stray cells that escape the initial treatment.

让免疫系统在生死搏斗后获得一些休息，这也许能让免疫系统更好地把最初治疗漏网的肿瘤细胞一网打尽。

The algorithms make the solution process correspond to the process of producing, growing and maturating of the T cells, the make use of the powerful maintaining variety mechanism in the developing process of Tcells to design the selection mechanism of the algorithm in order to improve the capability of the algorithm.

国外的代表性工作有：Hunt等人从模拟免疫系统角度提出了一种人工免疫模型；Ishida从仿生免疫系统的分布式处理出发，提出一种非集中控制的调节模型等〔1 - 4〕。

Therefore, the medicine for reconstituting immune system should have another function, namely, anti-HIV, or it couldn't cure AIDS.

但要用于重建免疫系统的药物必须是同时具有抗HIV作用的药物，否则重建免疫系统治疗艾滋病成为空话。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
