目的探讨高海拔地区健康军人唾液指标正常参考范围。方法受试者按海拔高度分为3 700m组(n=49)、4 300m组(n=57)、4 500m组(n=36)、5 300m组(n=21)及平原对照组(1 400m组,n=20),采集其唾液标本,应用高效液相色谱分析法测定唾液多项生化指标。结果随海拔高度增加,各项指标水平有不同程度增高;与平原对照组比较,除Mg2+、K+以外,5 300m组各项指标均显著增高,差异有统计学意义(P<0.01或P<0.05)。结论初步确定了不同海拔地区唾液指标正常参考范围,为高原地区兵员作训标准的制定提供了参考。
Objective To explore the normal reference range of saliva parameters for health servicemen in high altitude areas. Methods Subjects were divided into 3 700 m groups (n = 49), 4 300 m groups (n = 57), 4 500 m groups (n = 36), 5 300 m groups (n = 21) and plain control group 400m group, n = 20). The saliva samples were collected and the saliva biochemical parameters were determined by HPLC. The results showed that with the altitude increasing, the level of each index increased to some extent. Compared with the plain control group, the indexes of 5 300m group were significantly increased except for Mg2 + and K +, the difference was statistically significant (P <0.01 or P <0.05 ). Conclusion The normal reference range of saliva indicators in different altitudes is initially determined, which provides a reference for the formulation of standards for training soldiers in plateau areas.
