目的应用Meta分析综合评估β-2肾上腺素能受体基因(β-2AR)单核苷酸多态性(SNP)位点多态性与中国汉族儿童群体中哮喘易感性之间的关系。方法检索Pubmed、Embase、Web of Knowledge、中国知网、全文数据库、万方医学期刊数据库、维普医...目的应用Meta分析综合评估β-2肾上腺素能受体基因(β-2AR)单核苷酸多态性(SNP)位点多态性与中国汉族儿童群体中哮喘易感性之间的关系。方法检索Pubmed、Embase、Web of Knowledge、中国知网、全文数据库、万方医学期刊数据库、维普医药信息资源系统,收集β-2肾上腺素能受体基因多态性与中国汉族儿童哮喘易感性的相关文献。采用Stata14.0对符合纳入标准的文献做Meta分析。结果共纳入13篇文献,累计哮喘病例1959例,对照组1768例,所有入选文献均满足Hardy-Weinberg遗传平衡定律。分析结果显示,中国汉族儿童β-2AR基因的Arg16Gly位点突变基因G携带者(GG+GA)的哮喘发病风险较野生型纯合子(AA)比较,差异无统计学意义(P>0.05);Glu27Gly位点的突变基因G携带者(GG+CG)的哮喘发病风险较野生型纯合子(CC)比较,差异无统计学意义(P>0.05),而CG/GG的基因型显示差异具有统计学意义(P<0.05),OR=2.240,95%CI为1.337~3.754。结论β-2AR基因的16位点基因多态性与中国汉族儿童哮喘易感性无相关性,而27位点G突变基因可能是中国汉族儿童哮喘的保护因素。展开更多
美国波斯顿消息;哈佛大学Frank E.Speizer博士报告,补充雌激素10年以上的女性患哮喘的危险性是未用此药女性的1.5倍。 Speizer等人以1976年开始在茯理健康研究项目(Nurse’s Health Study)登记的121700例调查数据为基础,对9万多例进行...美国波斯顿消息;哈佛大学Frank E.Speizer博士报告,补充雌激素10年以上的女性患哮喘的危险性是未用此药女性的1.5倍。 Speizer等人以1976年开始在茯理健康研究项目(Nurse’s Health Study)登记的121700例调查数据为基础,对9万多例进行了探讨。结果发现过去补充雌激素的女性患哮喘的危险性升高50%。Speizer称:雌激素可能使哮喘易感性因子增多。展开更多

In some cases both illnesses exhibit similar pathomorphologic and clinical features, indicating common genetic basis of predisposing to development of disease. To assess genetic susceptibility we conducted association analysis of glutathione-S-transferases Mu (M), Theta (T) and Pi (P) gene polymorphism with disease development in 85 adult asthma, 60 COPD subjects and 64 control subjects. Present investigation of GST gene polymorphisms indicates that GSTM1 and GSTT null alleles are associated with predisposition for COPD and they do not appear to play a substantial role in susceptibility to BA. However, homozygote +/+ and heterozygote +/0 genotypes of GSTT1 revealed to be associated with increasing of IgE level in serum in BA patients. Our findings suggest that the 105 Val variant of GSTP1 contributed to the increasing risk of developing of both diseases, and more likely for COPD.展开更多
