摘要 目的探索端粒长度变化与女性卵巢功能的关系及其临床意义。方法在本院2006.3~2008.7住院治疗的各个年龄段的育龄女性及卵巢早衰患者正常卵巢组织标本66例,常规酚一氯仿法提取组织DNA后与端粒寡聚核苷酸探针进行Southern blot杂交、γ-32P检测及光密度扫描法测定端粒平均长度。结果各年龄段TRF值随着年龄的增长,其TRF值有下降的趋势,在20~35岁,36~55岁两年龄段之间无统计学差异,在35岁后其TRF值为6.64+0.21kb,在56岁后其TRF值为4.41+0.09kb,进行统计学分析后有统计学显著性差异。当FSH值小于30U/L时,其TRF值虽有下降趋势,无明显统计学差异,而FSH为31~40U/L时,其TRF值5.76±0.23kb,与前2组相比较有明显统计学差异;卵巢早衰组与正常绝组的TRF相比有明显统计学差异,卵巢早衰组女性的TRF值明显长于正常绝经组。结论对于正常女性来说,卵巢皮质TRF长度可以在一定程度上反映卵巢功能及生育能力,由于导致卵巢早衰的病因复杂及影响端粒长度的因素较多,导致端粒长度变化与卵巢功能相关性的临床意义尚未完全确定。
