目的通过对进驻高原作训期间健康官兵血脂的检测分析，了解高原高寒低氧环境对官兵血脂代谢的影响特点，为部队高原训练、处置突发事件的卫勤保障提供依据。方法随机抽取驻西宁地区(海拔2260m)和格尔木地区(海拔2860m)的急进、驻训2年、3年男性官兵300名，分成6组，每组50名;西宁地区一组、二组、三组，格尔木地区一组、二组、三组，各组分别代表两地的急进、驻训2年、3年及以上兵;检测分析血清胆固醇(totalcholesterol，TC)、甘油三酯(triglyceride，TG)、高密度脂蛋白(highdensitylipoprotein-cholesterol，HDL-C)、低密度脂蛋白(lowdensitylipoprotein-cholesterol，LDL-C)及红细胞胆固醇(E-CH)。结果西宁地区官兵在TC、HDL-C指标上二、三组比较有显著性差异(P＜0.05)，二组的结果明显低于三组，TG指标在一、二之间比较差异有统计学意义(P＜0.05)，一组TG明显低于二组，说明急进西宁地区官兵的血脂变化特点为:驻训第二年时降低更为显著;格尔木地区官兵的血脂指标在TC、HDL-C、LDL-C上一组分别与二、三组比较差异有统计学意义(P<0.01)，一组较二、三组明显降低，说明格尔木地区官兵血脂的变化特点为，一组官兵血脂指标就已发生明显降低，以TG指标为主。结论随着海拔的升高，男性官兵的血脂指标呈下降趋势;不同海拔地区官兵血脂指标的变化存在不同的特点，当海拔高度2800m以上时，一组官兵的血脂指标降低更为显著，提示应加强急进高原地区官兵血脂指标的监测。

Objective Through blood lipid examination anol analysis, to study the: impact of altitude, bitterly cold and hypoxic enviroment on blood lipid metabolism of servicemen in platean, thereby providing basis for training altitude troops, dealing with emergencies and medical service and management statroned. Methods 300 male officers and soldiers who just entered or were statroned in Xining (altitude 2260 m) and Golmud (altitude 2860 m) for two years or threc years were randomly selected and divided into six groups, 50 each. Their serum cholesterol (total cholesterol, TC), triglycerides (triglyceride, TG), high density lipoprotein (cholesterol(HDL-C), low density lipoprotein-cholesterol(LDL-C) and erythrocyte cholesterol (E-CH) were examined and analyzed. Results For Xining officers and soldiers, the TC and HDL-C between groups two and three were significantly different (P＜0.05), the results of groups two were significantly lower than those of groups three, TG between group one and two were significantly differenct (P＜0.05), TG in group one was significantly lower than those in groups two, indicating that lipid changes in Xining region are present in the officers and men, showing significant decrease of blood lipid in those stationed for two years. In Golmud officers and soldiers, lipid levels of TC, HDL-C , LDL-C, in groups one, significantly decreased (P<0.01), compared with other groups, especially for TG. Conclusions With the elevation of sea levels, male ifficers and soldiers have decreasing blood lipids, especially remarkable in higher than 2800m altitude, suggesting that in highland areas blood lipids should be monitored for the servicemen.
