摘要:

目的  探讨血管紧张素转换酶(ACE)和血管紧张素原 (AGT) 基因表达、基因多态性与青海孕产妇妊娠高血压疾病的相关性。  方法  选择210例妊娠高血压患者(HDCP组)和220例正常孕妇(CK组),运用限制性内切酶片段长度多态性聚合酶链反应(PCR-RFLP)方法检测AGT M235T、ACE I/D 基因多态性。  结果  CK组ACE基因 DD、ID、Ⅱ 所占比例分别为 28.18%、47.73%、24.09%,HDCP组分别为33.81%、51.90%、14.29%(P<0.05,故两组的ACE基因分布有差异),HDCP组和对照组ACE I/D多态性等位基因I和D频率分布有差异(P<0.05,HDCP组D等位基因频率高于对照组(χ2=5.188,P<0.05),ACE基因型分布符合Hardy-Weinberg遗传平衡(χ2=0.423,df=2,查表χ2 界值表,P>0.05,达到遗传平衡);CK组AGT基因 MM、MT、TT 所占比例分别为 24.09%、43.64%、32.27%,HDCP组分别为15.71%、42.86%、41.43%(P<0.05,故两组的AGT基因分布差异有统计学意义),HDCP组和对照组AGT M235T多态性等位基因M和T频率分布有差异性(P<0.05),HDCP组T等位基因频率高于对照组(χ2=6.796,P<0.05),AGT基因型分布符合Hardy-Weinberg遗传平衡(χ2=3.242,df=2,查表χ2界值表,P>0.05,达到遗传平衡)。  结论  ACE I/D多态性和AGT M235T多态性与青海省汉族妊娠期高血压疾病有关,D等位基因和T等位基因可能是妊娠高血压疾病的易感基因。

Abstract:

Objective  To investigate the relationship between angiotensin converting enzyme (ACE) and angiotensinogen (AGT) gene expression, gene polymorphism and pregnancy-induced hypertension in Qinghai.   Methods  A total of 210 pregnant hypertensive patients (HDCP group) and 220 normal pregnant women (CK group) were enrolled. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect AGT M235T and ACE I/D gene polymorphism.   Results  The proportions of ACE gene DD, ID, and Ⅱ in CK group were 28.15%, 47.73%, and 24.09%, respectively. The HDCP group was 33.81%, 51.90%, and 14.29%, respectively (P<0.05). The frequency distribution of ACE I/D polymorphic alleles I and D was different between HDCP group and CK group(P<0.05). D allele frequency was higher in HDCP group than in CK group (χ2=5.188, P<0.05). ACE genotype distribution was accorded with Hardy-Weinberg genetic balance(χ2=0.423, df=2, check table χ2 boundary value table, P>0.05, reach genetic balance). The proportions of MM, MT and TT in CK group was 24.09%, 43.64% and 32.27%, respectively. The HDCP group was 15.71%, 42.86%, and 41.43% respectively (P<0.05). HDCP group and CK group AGT M235T polymorphic alleles M and T frequency distribution were different (P<0.05). HDCP group T allele frequency was higher than the CK group(χ2=6.796, P<0.05). AGT gene were genotype distribution accorded with Hardy-Weinberg genetic balance (χ2=3.242, df=2, check table χ2 boundary value table, P>0.05, reaching genetic balance).  Conclusion  The ACE I/D polymorphism and AGT M235T polymorphism are associated with hypertensive disorder of pregnancy in Han nationality in Qinghai Province. D allele and T allele may be susceptible genes of pregnancy-induced hypertension.
