目的探讨跳伞期间空降兵经历的生理和心理应激是否会改变空降兵血浆的生化指标。方法调查了对照组（未跳伞组）和跳伞组空降兵血浆和血清中激素水平（皮质醇、生长激素、胰岛素、胰高血糖素、类皮素、血管紧张素Ｉ和ＩＩ、醛固酮）、酶活性（超氧化物岐化酶、谷胱甘肽过氧化氢酶和谷胱甘肽硫转移酶）、自由基损伤指标水平（丙二醛，）、肿瘤坏死因子α（ＴＮＦα）和主要热应激蛋白（ＨＳＰ７０）的差异性。结果跳伞组血清中生长激素、胰岛素、血管紧张素Ｉ、肾素活性和血浆中丙二醛、ＴＮＦα、ＨＳＰ７０等的水平比对照值显著高。结论这些变化有可能作为评估空降兵是否经历异常应激、评价他们的健康状况和选择空降兵的有用生物标志物，但需进一步研究。
Objective To investigate whether the physiological and psychological stress experienced by paratroopers during parachuting can change the biochemical indexes of the paratroopers. Methods The plasma and serum levels of hormones (cortisol, growth hormone, insulin, glucagon, corticoids, angiotensin I and II, aldosterone) in the control (parachute group) Activity (superoxide dismutase, glutathione peroxidase and glutathione S-transferase), free radical damage index level (MDA), tumor necrosis factor alpha (TNF @) and the main Difference of heat stress protein (HSP70). Results The level of growth hormone, insulin, angiotensin I, renin activity, plasma malondialdehyde, TNFα, HSP70 and other levels in the parachute group were significantly higher than those in the control group. Conclusions These changes are likely to be useful biomarkers for assessing whether paratroops experience abnormal stress, evaluating their health status and choosing paratroopers, but further studies are needed.
