目的探讨Y染色体非重组区HindⅢ酶切位点多态性与唐山地区汉族人群原发性高血压的关系。方法入选男性研究对象412名,原发性高血压患者225例、正常对照人群187名。所有研究对象用常规方法提取白细胞DNA。采用多聚酶链反应结合限制性内切酶(HindⅢ)方法检测 Y染色体非重组区HindⅢ酶切位点多态性。结果对照组和原发性高血压组Y染色体HindⅢ酶切位点多态性各基因型的差异有统计学意义(P=0.007)。HindⅢ(+)基因型较HindⅢ(-)基因型收缩压、舒张压、脉压和平均动脉压均明显降低(P<0.05)。结论 Y染色体HindⅢ酶切位点多态性与唐山地区汉族人群原发性高血压有关,可能是唐山地区汉族人群原发性高血压的一个遗传标志。 |

Objective Since males are at higher risk of cardiovascular diseases than females, the aim of the study was to examine whether there is an association between BP and a polymorphic Hind Ⅲ biallelic marker in nonrecombining region of Y chromosome in essential hypertension in Tangshan district in China. Methods In the study,225 patients with essential hypertension and 187 healthy people were enrolled into this study as control group. DNA was extracted from white blood cell. Segments of polymorphic Hind Ⅲ restriction site of the Y chromosome were amplified from DNA by polymerase chain reaction (PCR). PCR products were restricted with 10 U of Hind Ⅲ for a night at 37℃. The digested products were subjected to electrophoresis in 3% agarose gels, and stained with ethidium bromide. Results We amplified 178 controls (95.2%) and 216 essential hypertensive patients (96.0%) successfully. Hind Ⅲ(-) genotype was found in 45. 8 % of the men in essential hypertension and in 32.0% of the men in the controlled group. The Hind Ⅲ(-) genotype was significantly higher than that in the controls (x2 = 7.782, P = 0.007). However, the Hind Ⅲ(+) genotype was lower in SBP(133.16 mm Hg±21.60 mm Hg vs. 143.58 mm Hg±24.16 mm Hg,P0.001), DBP(82.82mm Hg±11.72 mm Hg vs. 86.82 mm Hg±12.65 mm Hg,P=0.001),pulse pressure(50.34 mm Hg±14.31 mm Hg vs. 56.76 mm Hg±14.20 mm Hg, P0.001) and mean arterial pressure(99.59 mmHg±14.19 mm Hg vs. 105.74 mm Hg±15.31 mm Hg,P0.001) than the Hind Ⅲ(-) genotype. Conclusion Polymorphic HindⅢ restriction site of the Y chromosome seemed to be associated with essential hypertension in Tangshan district in China. |
