Estrogen receptor ? (ER?) gene polymorphism of perimenopausal syndrome patients with liver qi stagnation syndrome (LQSS) / 中华中医药杂志

ABSTRACT

Objective:To investigate the association between polymorphisms of estrogen receptor ? (ER?) gene (rs3020444) and perimenopausal syndrome (PS) in patients with liver qi stagnation syndrome (LQSS). MethedsThe ER?T/C genotype in 100 patients of PS of LQSS type (PS-LQSS group),86 patients of PS of non-LSDS type (PS-non-LQSS group) and 100 healthy subjects (control) was determined by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) assay. Results:Partitions of ?2 method showed that the higher prevalence of ER?-TT genotypes was noted in PS-LQSS group (?2=8.307,P=0.004),and the higher prevalence of T alleles was noted in PS-LQSS group (?2=7.129,P=0.008). and Multinomial logistic-regression indicated that the odds ratios (OR) of the ER?-TT genotypes vs TC/CC for PS-LQSS was 2.222 (95%CI1.172-4.744,P=0.015) after adjusting for common miscellaneous factors. Conclusions:It was suggested that ER?-TT genotypes was significantly associated with PS-LQSS,and ESR?-TT may be one of the genes that contribute to PS-LQSS.
