目的

探讨转化生长因子β受体1(TGFBR1)基因位点rs12346650及结合该基因的miR-938编码基因位点rs2505901单核苷酸多态性(SNP)与出血性脑卒中(HS)的关联。

方法

采用病例-对照研究方式,以自2008年1月至2013年7月淮安市第一人民医院和淮阴区医院收治的239例急性HS患者为病例组,993例无脑卒中史的社区人群为对照组。收集性别、年龄、身高、体质量等基本人口信息,及糖尿病史、高血压病史,测量血压并检测血糖(GLU)、甘油三酯(TG)、胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)。采用聚合酶链式反应-限制性内切酶片段长度多态性(RFLP)的方法进行基因分型。

结果

病例组和对照组间rs2505901和rs12346650的基因型、等位基因型频率差异均无统计学意义(P>0.05)。应用Logistic回归模型校正混杂因素年龄、性别、Ⅱ型糖尿病、TC、TG、HDL-C和LDL-C后,结果仍无统计学意义(P>0.05)。进一步按性别对两个位点与HS的关联性进行分层分析,男性中rs2505901位点显性模型有统计学意义[比值比(OR)=0.641,95%置信区间(CI):0.417~0.984]。rs12346650位点相加模型和隐性模型均有统计学意义(OR=1.369,95%CI:1.020~1.836;OR=2.092,95%CI:1.243~3.520)。但校正混杂因素后,模型差异无统计学意义(P>0.05)。在女性人群中,而校正协变量后rs12346650位点隐性模型有统计学意义(OR=0.318,95%CI:0.114~0.891)。

结论

本研究初步发现TGFBR1基因rs12346650、MIR938基因rs2505901多态性与HS存在关联。

Objective

To investigate the association between rs12346650 G>A polymorphisms in transforming growth factor β receptor 1 (TGFBR1) gene and rs2505901 C>T polymorphisms in microRNA-938 and hemorrhagic stroke (HS).

Methods

A total of 239 patients with acute HS and 993 controls from a community population were recruited in this study. The basic information of age, sex, height, weight, diabetes history and hypertension history were collected, and blood samples were collected to test blood pressure (BP), glucose (GLU), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C). Using polymerase chain reaction-restrictive fragment length polymorphism (PCR-RFLP) to determine genotype.

Results

The genotype frequencies of rs2505901 and rs12346650 have no statistical difference between HS case group and control group as well as after adjusted for age, sex, diabetes history, hypertension history, TC, TG, HDL-C and LDL-C (P>0.05). Further stratification analysis by sex indicated that the dominant genetic model of rs2505901, the additive and recessive model of rs12346650 showed statistical significance for male HS and OR (95%CI) were 0.641 (0.417-0.984), 1.369 (1.020-1.836) and 2.092 (1.243-3.520) respectively. But the association weren’t significant after adjusted for confounding factors as above. For female, the receive model of rs12346650 showed significantly association with HS and the OR(95%CI) was 0.318 (0.114-0.891) after adjusted for confounding factors.

Conclusion

The finding in the present study suggested that there was weak association between MIR938 and TGFBR1 genetic polymorphisms and HS.
