摘　　要：目的研究某部特勤人员高强度军训5km武装越野跑后肾损伤分子-1（kidney injury molecule-1，KIM-1）、中性粒细胞明胶酶相关脂质运载蛋白（neutrophilgelatinase associated lipocalcin，NGAL）变化特征，探讨其作为早期肾损伤诊断标志物的可能性。方法观察某部海训人员，行5km武装越野跑，观察训练前后不同时间的尿液uKIM-1、uNGAL、尿微量白蛋白、NAG含量。其中随机100人抽静脉血检查sKIM-1、sNGAL。结果5km武装越野跑结束后即刻，uKIM-1、uNGAL浓度分别较基线升高70．55％、92．85％，6h后分别升高104．21％、142．79％。训练后即刻KIM-1、NGAL血清与尿液浓度显著正相关，P〈0．05，各时间段uKIM-1、uNGAL的ROC曲线下面积大于白蛋白、NAG。uKIM-1、uNGAL的ROC曲线下面积大于sKIM-1、sNGAL。结论5km武装越野跑后尿KIM—1、NGAL在训练后即刻开始升高，6h为峰值，诊断肾损伤效能优于尿白蛋白、NAG。uKIM-1、uNGAL可以早期、便捷、敏感地反映高强度军训肾损伤。Objective To approach the characters of the serum and urine KIM-1, NGAL after 5 km armed military training in a special forces, and discuss whether the biomarkers is able to early detect the kidney injury caused by high intensive military training. Methods The urine markers such as uKIM-1, uNGAL, albumin, NAG before and 20 minutes, 6 hours, 24 hours after 5 km armed military training were observed. Venous blood samples were collected to test sKIM-l, sNBAL from 100 soldiers who were randomly selected. Results The uKIM-1, uNGAL were increased immediately after the training, compared with the baselines. The urine concentrations of the uKIM-1, uNGAL increased 70.55%, 92.85% at the point of 20 minutes, 104.21%, 142.79% at the point of 6 hours respectively. The uKIM-1 was significantly positively correlated with the sKIM-1 immediately after training （P 〈0.05, r=0.62）, and the uNGAL was moderately correlated with the sNGAL （P 〈0.05, r=0.53）. Receiver operating characteristic （ROC） analysis showed the area under the curve （AUC） of the uKIM-1, uNGAL were more than those of albumin, NAG, sKIM-I, sNGAL in any time after training. Conclusion After 5 km armed military traning, the uNGAL, uKIM-1 increased immediately. They reach the peak values at the point of 6 hours, and the diagnosis efficiencies were better than those of urine protein, albumin, NAG. The uKIM-1, uNGAL are considered being early, convenient, sensitive, reliable biomarkers to diagnose the kidney injury caused by high intensive military training.
