摘要 目的:探讨长期高原作业是否能造成精子DNA的损伤。方法:以53例驻守低海拔地区的部队官兵为对照组,51例高海拔地区的部队官兵为观察组进行调查和对照研究,通过单细胞凝胶电泳技术和染色质扩散实验,检测精子DNA的损伤情况。结果:观察组在进入高原前的各项指标与对照组之间均无明显差异(P>0.05)。观察组的总彗星细胞发生率、各级彗星细胞发生率(G1、G2、G3)和DNA异常精子百分率在进入高原地区前分别为:(5.56±3.98)%、(3.72±1.85)%、(1.57±1.07)%、(0.27±0.34)%和(16.59±12.07)%,进入高原地区半年后均有升高,分别为:(11.15±8.59)%、(5.97±3.26)%、(3.83±2.13)%、(1.35±1.53)%和(22.03±15.33)%,与半年前相比差异显著(P<0.05);二级彗星细胞发生率(G2)和DNA异常精子百分率在1年后有所下降,分别为(3.32±1.83)%和(20.54±15.52)%,但仍比进入高原地区前有明显升高(P<0.05)。结论:长期在高原地区作业可引起精子DNA损伤,但对生育潜能的影响有待进一步研究。加强高原地区作业人员的男性生殖健康预防保健工作仍然十分重要。 Objective: To investigate whether long working in the high-altitude area can damage sperm DNA in men. Methods: We enlisted 51 service men stationed on the plateau in an observation group and another 53 living in the low-altitude area in a control group. We detected and compared the damages to sperm DNA in the semen samples from the two groups using single cell gel electrophoresis and the sperm chromatin dispersion test. Results : The percentages of total, G1, G2 and G3 comet cells and abnormal sperm of the observation group were (5.56 ± 3.98) %, (3.72 ± 1.85) %, ( 1.57 ± 1.07) %, (0.27 ± 0.34) % and ( 16.59 ± 12.07 ) %, respectively, before stationed on the plateau, but significantly increased at 6 months of plateau life ( [ 11.15 ± 8.59 ± %, 15.97 ± 3.26 ± %, E 3.83 ± 2.131%, E 1.35 ± 1.531% and 122.03 ± 15.33 ± %, P 〈 0.05). The percentages of G2 comet cells and abnormal sperm were decreased to (3.32 ± 1.83) % and (20.54 ± 15.52) % at 12 months, but still significantly higher than the baseline ( P 〈 0.05 ). Conclusion : Long working on the plateau may damage sperm DNA, but its influence on male fertility deserves further investigation. Therefore, it is important to reinforce reproductive health protection for males working on the plateau. Natl J Androl, 2012, 18 (3) : 239 -242
