摘要：

目的 评价肾素-血管紧张素系统中的血管紧张素转换酶(ACE)基因插入/缺失（I/D）、血管紧张素原（ANG）基因M235T和血管紧张素Ⅱ受体-1（[STBX]AT1R[STBZ]）基因A1166C多态性与儿童青少年高血压易感的关联。 方法 计算机检索EMBASE、PubMed、HUGE、中国知网、维普数据库、万方数据库和中国生物医学文献数据库，检索时间均为建库至2015年11月27日，纳入3个基因多态性与儿童青少年高血压关联的病例对照研究。提取高血压组和对照组基因型和等位基因频率，行文献偏倚风险评价。采用Stata 12.0软件，分别以隐性、显性、共显性、相加和等位基因模型对高血压组和对照组上述3个基因多态性与高血压的关联行Meta分析。根据对照组人群和种族行亚组分析。 结果 7篇文献进入Meta分析，病例组824例，对照组1 731例。7篇文献存在中等偏倚风险。①纳入6篇文献的ACE基因I/D多态性在隐性模型下与儿童青少年高血压的发病风险关联（OR=1.405, 95%CI：1.073~1.840, P=0.013）。②上述5种分析模型，ANG基因M235T和[STBX]AT1R[STBZ]基因A1166C多态性（分别纳入3和2篇文献）与儿童青少年高血压发病风险均无关联。③亚组分析结果显示，２篇文献肥胖人群的ACR基因I/D多态性在隐性、相加和等位基因模型下显著增加儿童青少年高血压的发病风险（隐性模型:OR=1.564 , 95%CI:1.054~2.321, P=0.026；相加模型：OR=2.017， 95%CI:1.137~3.576，P=0.016; 等位基因模型：OR=1.406， 95%CI： 1.076~1.838，P=0.013)。；对一般儿童青少年人群的高血压发病风险无影响，且与种族和高血压分类方法无关。 结论 ANG基因M235T、[STBX]AT1R[STBZ]基因A1166C多态性与儿童青少年高血压发病风险无关联，ACE基因I/D多态性可能与肥胖儿童青少年高血压的发病风险关联。

Abstract:

Objective To explore the association between the genetic markers angiotensin converting enzyme (ACE) (I/D), angiotensinogen (ANG) (M235T) and angiotensin Ⅱ receptor-1 [STBX]AT1R[STBZ] (A1166C) and risk of hypertension in pediatric subjects. Methods EMBASE, PubMed, Hartford User Group Exchange (HUGE), CNKI, VIP, Wanfang data and CBM database were searched for the case-control studies on the association of three gene polymorphisms with hypertension in pediatric patients from the establishment to November 27th 2015. Data extraction, quality assessment and pooled analysis were conducted. Meta-analysis on the association of three gene polymorphisms with hypertension between hypertension group and control group under recessiveness, dominance, co-dominance, addition and allele gene models were performed. Statistical analysis was performed by Stata 12.0 software. Results A total of 824 patients and 1 731 controls from 7 case-control studies with moderate bias risk were included. An association between hypertension and ACE (I/D) D variant was identified in 6 included studies in the meta-analysis under recessive model (OR=1.405, 95%CI =1.073-1.840, P=0.013). Neither ANG (M235T) polymorphism in 3 enrolled studies nor [STBX]AT1R[STBZ] (A1166C) polymorphism in 2 enrolled studies was associated with hypertension in pediatric population under recessiveness, dominance, co-dominance, addition or allele gene models. Subgroup analysis revealed that ACE (I/D) D variant was associated with an increased risk of hypertension in obese pediatric population under recessive model（OR=1.564 , 95%CI:1.054-2.321, P=0.026), additive model (OR=2.017, 95%CI:1.137-3.576, P=0.016) and allele model (OR=1.406, 95%CI: 1.076-1.838, P=0.013). There were no significant differences in the frequencies distribution of ACE (I/D) between two groups in general population by considering ethnicity and classification of hypertension. Conclusion No significant association was found between ANG M235T, [STBX]AT1R[STBZ] A1166C polymorphisms and hypertension in pediatric population. The ACE (I/D) polymorphism might be associated with susceptibility to hypertension in the obese pediatric population.
