摘要:

背景:由于基因多态性分布存在年龄差异,骨质疏松所致的全身性骨骼疾病在不同年龄人群中的发病率也不同。

 

目的:分析雌激素受体基因多态性分布在老年女性髋部骨质疏松发病中的年龄差异情况。

 

方法:选择老年女性髋部骨质疏松患者72例作为骨质疏松组,同期选择健康体检的非髋部骨质疏松老年女性72例作为对照组,两组的年龄、合并疾病等状况对比差异无显著性意义(P > 0.05),具有可比性。同时进行雌激素受体基因XbaⅠ与PvuⅡ位点的PCR-RFLP分析与骨密度检测。

 

结果与结论:骨质疏松组的等位基因X的比例和基因型XX的比例显著高于对照组。XX基因型患者的年龄明显大于Xx和xx基因型(P < 0.05)。Logistic多元回归的线性相关分析显示年龄与XX基因型的髋部骨质疏松发生存在明显的相关性(P < 0.05)。说明雌激素受体基因XX位点的多态性对于老年女性髋部骨质疏松发病有一定的影响,且有相关的年龄分布差异。

Abstract:

BACKGROUND: Since the age differences exist in gene polymorphism, the incidence of osteoporosis-induced systemic skeletal diseases is varied in different age groups.

 
OBJECTIVE: To investigate the age differences of estrogen receptor gene polymorphisms in the elderly women with hip osteoporosis.
METHODS: Seventy-two elderly women with hip osteoporosis were selected as osteoporosis group, and another 72 non-hip osteoporosis elderly women served as controls. There was no significant difference in age and diseases between two groups (P > 0.05). Simultaneously, PCR-RFLP at loci of Xba I and Pvu II and bone mineral density were analyzed and tested.

RESULTS AND CONCLUSION: The distribution rates of X and XX alleles were significantly higher in the osteoporosis group than the control group (P < 0.05). Patients with the XX genotype were significantly older than those with Xx and xx genotypes (P < 0.05). Logistic regression linear correlation analysis showed that the age was obviously correlated with the occurrence of hip osteoporosis in patients with XX genotypes (P < 0.05). These findings indicate that gene polymorphisms at XX locus of estrogen receptor gene have some influences on the occurrence of hip osteoporosis in elderly women, and there is the age-related distribution difference.
