    • 摘要: 目的 探讨血管紧张素原(AGT)基因M235T位点多态性与高尿酸血症(HUA)易感性的关系.方法 以2018年5月至2020年4月江门市中心医院风湿免疫科312例HUA患者为高尿酸血症组,并以同期286例原发性痛风患者为痛风组,357例正常人群为正常组.比较三组的AGT基因M235T位点多态性,分析AGT基因M235T位点多态性与HUA、痛风发生的关系;根据HUA治疗效果将高尿酸血症组分为有效组及无效组,比较两组的AGT基因M235T位点多态性,分析AGT基因M235T位点多态性与HUA治疗效果的关系.结果 高尿酸血症组、痛风组和正常组的MM、MT、TT实际频数与理论频数比较,差异均无统计学意义(P>0.05);高尿酸血症组、痛风组的AGT基因M235T位点MT、TT检出率高于正常组(P0.05).结论 AGT基因M235T位点多态性是影响HUA及痛风发生的危险因素,但与HUA治疗效果无关.

    • 摘要: Objective Explore whether the angiotensinogen gene M235T polymorphism could affect the occurrence of diabetic nephropathy. Methods 300 cases of diabetes patients were divided into three groups according to the ratio of urinary proteinuria and urine creatinine(ACR):DM group,microalbuminuria group and macroalbuminuria group. 100 cases of healthy people were selected as control group. Conventional indicators were detected. M235T polymorphism were detected by polymerase chain reaction - restriction fragment length polymorphism technique. Results Normal group and the diabetic group,microalbuminuria,macroalbuminuria group genotypes were in accordance with Hardy - Weinberg equilibrium law. M235T genotype distribution and allele frequency in normal group and diabetic group has no significant difference( P >0. 05). M235T genotype dis-tribution and allele frequency in DM group,microalbuminuria and macroalbuminuria group has no significant difference. Conclusion There is no correlation between angiotensinogen gene M235T polymorphism and diabetic nephropathy of the peple in the region.%目的探讨血管紧张素原基因 M235T 是否影响糖尿病肾病的发生。方法收集收治的糖尿病患者300例,根据尿蛋白尿和尿肌酐的比值(ACR)分为三组:单纯糖尿病组(ACR <30 mg/ g),微量蛋白尿组(30 mg/ g < ACR <300 mg/ g),大量蛋白尿组(ACR >300 mg/ g)。另收集健康体检人群100例作为对照组。检测各组常规指标,采用聚合酶链反应-限制性片断长度多态性技术进行 M235T 多态性位点多态性检测。结果对照组和单纯糖尿病组、微量蛋白尿组、大量蛋白尿组基因型分布均符合 Hardy - Weinberg 平衡定律;对照组和糖尿病组 M235T 基因型分布和等位基因频率无统计学差异( P >0.05);单纯糖尿病组、微量蛋白尿组和大量蛋白尿组 M235T 基因型分布和等位基因频率无统计学差异( P >0.05)。结论在本区域人群中,血管紧张素原基因 M235T 多态性与糖尿病肾病无相关性。

    • 摘要: 目的 研究血管紧张素原(AGT)基因多态性位点M235T、A-6G、A-20C及其单倍型(M235T-A-6G-A-20C)与中国部分原发性高血压(EH)高发的少数民族(蒙古族、哈萨克族、藏族)EH易感性的关系,比较AGT对不同民族人群EH发病风险的影响.方法 应用聚合酶链反应(PCR)及限制性片段长度多态性(RFLP)技术判定基因型,采用Haploview软件进行单倍型分布分析.结果 哈萨克族EH组-6G分布显著高于对照组(42.34% vs 36.98%,P=0.009).藏族EH组20C分布显著低于对照组(18.17% vs 23.19%,P=0.038).哈萨克族EH组M-A-A的分布频率显著低于对照组(38.16% vs 47.50%,P=0.001),而EH组M-G-A分布频率显著高于对照组(16.20% vs 8.61%,P=0.000).藏族EH组T-A-A分布频率显著高于对照组(71.89% vs 64.15%,P=0.006).结论 AGT多态性与EH的相关性具有显著的种族异质性,M235T、A-6G、A-20C与中国蒙古族EH发病风险无关,-6G与哈萨克族EH易感性升高相关,而20A可能降低藏族EH的发病风险;单倍型M-G-A和T-A-A可能分别与哈萨克族和藏族EH易感性升高相关,而M-A-A可能是哈萨克族抗EH的保护性因素.
