摘　　要：背景高血压是最常见的慢性心血管病,也是全球疾病负担的主要原因,我国高血压发病率存在着地域差异,其中高寒地区高血压患者明显多于非高寒地区,这主要由生活环境和遗传因素决定,本文将从遗传学的角度对高血压的发病进行研究。目的探究β1-肾上腺素受体(ADRB1)、血管紧张素Ⅱ-1型受体(AGTR1)基因多态性与高寒地区高血压的关系。方法选取2014年8月—2017年2月于佳木斯大学附属第一医院高血压和心内科门诊就诊及住院的符合研究标准的高血压患者1084例,其中546例进行ADRB1基因检测(记为高寒地区1组),702例进行AGTR1基因检测(记为高寒地区2组)。选取同期于本院进行体检的健康且未服用任何药物的志愿者169例(记为对照组受试者)。采用荧光染色原位杂交法检测所有受试者ADRB1、AGTR1基因型。比较高寒地区1组与对照组受试者ADRB1基因型、等位基因频率,高寒地区2组与对照组受试者AGTR1基因型、等位基因频率;并分析高寒地区高血压患者与非高寒(北京、湖南、福建)地区高血压患者及高寒地区健康人群与非高寒(北京、湖南、福建)地区高血压患者ADRB1、AGTR1基因型、等位基因频率。结果高寒地区1组与对照组受试者ADRB1基因型比较,差异无统计学意义(P>0.05);高寒地区1组与对照组受试者ADRB1等位基因频率比较,差异有统计学意义(P<0.05)。高寒地区2组与对照组受试者AGTR1基因型、等位基因频率比较,差异无统计学意义(P>0.05)。高寒地区1组高血压患者与北京地区、湖南地区、福建地区高血压患者ADRB1基因型、等位基因频率比较,差异无统计学意义(P>0.05)。高寒地区2组高血压患者与北京地区高血压患者AGTR1基因型、等位基因频率比较,差异无统计学意义(P>0.05);高寒地区2组高血压患者与湖南地区、福建地区高血压患者AGTR1基因型、等位基因频率比较,差异有统计学意义(Background Hypertension is the most common chronic cardiovascular disease and the leading cause of the global disease burden.There are regional differences in the incidence of hypertension in China,and more patients with hypertension are found in alpine areas than in non-alpine areas,which is mainly determined by living environment and genetic factors.This article will study the pathogenesis of hypertension from the perspective of genetics.Objective To explore the association of gene polymorphisms inβ1-adrenergic receptor(ADRB1)and angiotensionⅡ-1 receptor(AGTR1)with hypertension in alpine areas.Methods A total of 1084 patients with hypertension who met the research criteria seeking medical advice and hospitalization in Department of Hypertension and Department of Cardiology in the First Affiliated Hospital of Jiamusi University from August of 2014 to February of 2017 were selected.Among them,546 cases were tested for ADRB1 genotypes(recorded as Group 1),and 702 cases were tested for AGTR1 genotypes(recorded as Group 2).And 169 healthy volunteers without taking any medicine were selected as the control group during the same period.The fluorescence in situ hybridization method was used to detect ADRB1 genotypes and AGTR1 genotypes.The ADRB1 genotypes and frequency of alleles between Group 1 and control group were compared and the AGTR1 genotypes and frequency of alleles between Group 2 and control group were compared.The ADRB1 genotypes and allele frequency,and AGTR1 genotypes and allele frequency between patients with hypertension in alpine areas and non-alpine areas(Beijing,Hunan,and Fujian),and healthy people in alpine areas and patients with hypertension in non-alpine areas(Beijing,Hunan,and Fujian)were compared.Results There was no significant difference in the ADRB1 genotypes between Group 1 and control group(P>0.05),while there was significant difference in the ADRB1 allele frequency between Group 1 and control group(P<0.05).There was no significant difference in the AGTR1 genotypes and allele frequency
