Methods: Seventy-four peri-menopausal and menopausal women with depressive disorder met ICD-10 and CCMD-3 assessment criteria for depressive disorder were recruited. ERβ gene Rsa1 polymorphism was analyzed with PCR-RFLP. Serum levels of estrogen, FSH and LH were measured by magnetism-ELISA. Results: The respective frequency of ERβ gene Rsa1 polymorphism was no significant difference between women with depressive disorder and the healthy women (χ 2=1.106,P>0.05). The serum level of estrogen was lower in women with depressive disorder than in the healthy women (P<0.05). No difference was found for FSH and LH between two groups. Conclusion: ERβ gene Rsa1 polymorphism may be not associated with depressive disorder in the peri-menopausal and menopausal women. The serum level of estrogen is associated with depressive disorder in the peri-menopausal and menopausal women.展开更多
[目的]探讨汉族人维生素D受体(vitamin D receptor,VDR)基因多态性与腰椎间盘退变(lumbar discdegeneration,LDD)的关系。[方法]收集182例汉族人静脉血标本和腰椎MRI,其中对照组101例,病例组81例。用聚合酶链反应-限制性片段长度多态性(...[目的]探讨汉族人维生素D受体(vitamin D receptor,VDR)基因多态性与腰椎间盘退变(lumbar discdegeneration,LDD)的关系。[方法]收集182例汉族人静脉血标本和腰椎MRI,其中对照组101例,病例组81例。用聚合酶链反应-限制性片段长度多态性(PCR-restriction fragment length polymorphism,PCR-RFLP)法测定2组标本的VDR基因TruⅠ和FokⅠ酶切位点多态性;根据MRI显示的信号差异按Schneiderman分级法确定各个体腰椎间盘的退变程度,分无、轻、中、重4组。分析病例对照组中基因型、等位基因频率的分布规律,分析其中小于45岁(包括45岁)者基因型及基因频率分布与椎间盘退变程度的关系。[结果]对照组中FokⅠ和TruⅠ的等位基因频率分布为:F59.4%,f40.6%和T79.2%,t20.8%;病例组中FokⅠ和TruⅠ等位基因频率的分布为:F53.7%,f46.3%和T80.9%,t19.1%,二组中的分布差别无统计学意义,P>0.05;在MRI分组中VDR基因TruⅠ和FokⅠ酶切位点的基因型和等位基因频率在组中分布差异也无显著性,P>0.05。[结论]VDR基因TruⅠ和FokⅠ酶切位点多态性和汉族人LDD无关。展开更多
文摘目的:探讨IgE低亲和力受体(FeaRⅡ,CD23)基因点多态性与哮喘易感性的关系。方法:聚合酶链反应-限制性片段长度多态性分析(PCR-RFLP)检测外显子9上的G→A碱基突变。结果:本实验未能发现基因外显子9上存在G→A突变, PAGE电泳检测不到限制性片段长度多态性(restriction fragment length polymorphism,RFLP)。结论:所研究人群中FceRⅡ基因不存在(G→A)点多态性。
