摘  要:目的明确雌激素受体(ER)-α不同基因型在广西壮族妇女中分布,了解其不同基因与广西壮族绝经后妇女血清碱性磷酸酶(ALP)水平和跟骨骨密度(BMD)的关系。方法对612例广西壮族绝经妇女采外周静脉血5 ml,提取DNA检测ER-α基因,用试剂盒法测定相应标本的血清ALP。用超声BMD仪检测受试者右侧跟骨BMD。结果 60岁之前绝经妇女ER-α所有基因型的ALP和BMD都是随着年龄增大而降低的,各基因型的同一年龄组之间的ALP和BMD均无明显差别(P>0. 05)。而60岁后ER-αPvuⅡ酶切的P等位基因与同一年龄组其他4个基因组比较,ALP明显升高(P<0. 05),而BMD明显降低(P<0. 05); 65岁后ER-αXbaⅠ酶切的Xx等位基因与同一年龄组其他4个基因组比较,ALP明显降低,而BMD明显提高(P<0. 05)。结论 ER-α的P等位基因是绝经后骨质疏松易感基因,此类基因型绝经妇女应该提前防治;而ER-α的Xx等位基因的BMD较高,不易患绝经后骨质疏松。应该根据不同基因型个体采取个性化防治。Objective To determine the distribution of different oestrogen receptor-beta genes in women of Guangxi Zhuang nationality and understand the relationship between different genes and serum alkaline phosphatase level and bone mineral density(BMD)in postmenopausal women of Guangxi Zhuang nationality.Methods 5 ml peripheral venous blood was collected from 612 post-menopausal women in Guangxi Zhuang nationality,DNA was extracted to detect the estrogen receptor-sterile gene.The BMD of the right calcaneal was measured by ultrasonic bone density meter.Results Before the age of 60,alkaline phosphatase and BMD of all estrogen receptor-alpha genotypes in postmenopausal women decreased with aging and there was no significant difference between alkaline phosphatase and BMD in the same age group of each genotype(P>0.05).And estrogen receptor after 60 years of age-alpha PvuⅡenzyme P allele compared with the same age group of four other genomes,alkaline phosphatase increased significantly(P<0.05)and BMD decreased obviously(P<0.05).After the 65-year-old estrogen receptor-alpha XbaⅠenzyme Xx alleles and other four genome in the same age groups,alkaline phosphatase decreased obviously and BMD increased significantly(P<0.05).Conclusions The P allele of estrogen receptor-positive is a predisposing gene of postmenopausal osteoporosis,which is more susceptible to postmenopausal osteoporosis.The Xx allele of estrogen receptor(alpha)has higher BMD and is less susceptible to postmenopausal osteoporosis.
