Objective To study the serum levels of IL-2 and IFN-r in patients with condylomata acuminate resulted from human papillomavirus infection, and to explore the effect of infection on the patients' cytokine profiles.

目的 对人乳头瘤病毒感染所致尖锐湿疣患者的IL-2和IFN-r水平进行观察，探讨HPV感染对机体细胞因子的影响。

ABSTRACT Living in a weightless environment often produces some adaptational and pathophysiological changes refered to as adverse effects.

在航天失重环境停留可引起机体多个系统发生一系列适应性改变和一些病理生理性的变化。

Due to β-adrenergic receptor is widely distributed in the body organ systems, the more adverse reactions.

因β受体广泛分布于机体各系统器官，因此不良反应较多。

At the beginning the number was decrease rapidly, then slowly. There were still some MSCs alive 8 week after transplant. Conclusion: The mouse's MSCs can survive more than 8 week in subcutaneous tissue of allogene mouse. MSCs were hypoimmunogenic.

小鼠MSCs植入同种异体小鼠皮下8周后仍能存活，MSCs在体内保持低免疫原性的特点，同种异体与同种同基因MSCs在诱导机体免疫应答方面无明显差异。

Growth is said to be allometric, i.e., there are constant relationships among body components.

生长被认为是异速生长的，也就是说，机体组成之间存在固定的关系。

Be good at lienal medicaments can improve function of immunity of airframe of patient of cancer of the liver, the medicaments that change Yu is ameliorable cancer of the liver is local small environment is disorder condition, restrain tumor capillary to generate, improve immunity to check status thereby.

健脾药物可提高肝癌患者机体免疫功能，化瘀药物可改善肝癌局部微环境紊乱状态，抑制肿瘤微血管生成，从而改善免疫抑制状态。

Cysteamine exists in the living animals and plants, owing to sulfhydryl and amido it has special biological function to participate in the normal metabolic process , for example, the decreasing of Somatostatin, the influence of the synthesis and the excrete of GH, etc .

半胱胺是天然存在于动物、植物和人体内的生理活性物质，含有活性的巯基和氨基具有特定生物学功能，参与正常代谢过程，如降低机体生长抑素（Somatostatin，SS）水平 [2，3]，影响GH的合成和分泌等[4]。

The US scientists found that the appendix acted as a "good safe house" for bacteria essential for healthy digestion, in effect re-booting the digestive system after the host has contracted diseases such as amoebic dysentery or cholera, which kill off helpful germs and purge the gut.

美国科学家发现，阑尾充当自然消化功能必需菌的&安乐所&，在机体感染诸如阿米巴痢疾或霍乱，这种能杀灭有益菌，清洁肠道的疾病之后，实际上，重新启动消化系统。

This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

ConclusionF022 from Radix Isatidis can not only destroy the structure of endotoxin, but also obstruct the signal transduction pathways of LPS. F022 may be a strong antiendotoxin fraction in drugs research and development.

结论F022部位不仅直接破坏内毒素结构，且阻断内毒素引起的信号传导通路，从而抑制机体炎性因子的过度释放、抑制膜结构伸展刺突蛋白和丝裂原活化蛋白激酶的表达，从分子水平阐明了板蓝根中活性部位F022抗内毒素的分子机理。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
