摘  要:目的 探讨H型高血压患者脂质过氧化损伤和血管内皮功能变化情况.方法 纳入2012年2月至2013年1月海南省人民医院门诊及住院原发性高血压病患者169例,根据血浆同型半胱氨酸(Hcy)水平分为H型高血压组86例(Hcy≥10 μmol/L)和对照组83例(Hcy< 10 μmol/L),比较2组24h平均血压、血浆Hcy、丙二醛、超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、谷胱甘肽、一氧化氮、一氧化氮合成酶(NOS)、肱动脉血管内皮依赖性舒张功能(EDFMD)差异.结果 H型高血压组和对照组24 h平均血压差异无统计学意义[(131.6±7.1)/(85.4±2.9) mmHg(1mmHg =0.133 kPa)比(132.1±7.1)/(85.1±3.2)mmHg] (P>0.05).H型高血压组SOD、GSH-Px、谷胱甘肽、一氧化氮、NOS和EDFMD水平均低于对照组[(81±19) IU/ml比(96±18) IU/ml、(161±28) U/L比(174±27) U/L、(0.8±0.2)mmol/L比(0.9±0.2)mmol/L、(72±15) μmol/L比(82±14) μmol/L、(2.0±0.4) U/ml比(2.7±0.4) U/ml、(9.3±0.9)%比(13.7±0.8)%](均P<0.05),血浆Hcy和丙二醛水平高于对照组[(13.3±0.8)μmol/L比(7.6±0.6)μmol/L、(12.3±2.9) μmol/L比(9.1 ±3.0)μmol/L](均P<0.05).结论 H型高血压患者存在脂质过氧化损伤和血管内皮功能障碍,应采取措施积极干预.Objective To evaluate the lipid peroxide injury and vascular endothelial function in patients with H type hypertension.Methods Totally 169 patients with primary hypertension from February 2012 to January 2013 were enrolled and divided into H type hypertension group [homocysteine (Hcy ≥10 μmol/L,86 cases] and control group (Hcy 〈 10 μmol/L,83 cases).The mean value of 24 hours ambulatory blood pressure,plasma malondialdehyde (MDA),superoxide dismutase (SOD),glutathione peroxidase (GSH-PX),glutathione (GSH),nitric oxide (NO),nitricoxide synthase (NOS),Hcy and endothelium-dependant flowing-mediated dilation (EDFMD) were detected and compared between the two groups.Results There was no significant difference in the mean value of ambulatory blood pressure between H type hypertension group and control group [(131.6 ± 7.1)/(85.4 ± 2.9) mmHg vs (132.1 ± 7.1)/(85.1 ± 3.2) mmHg] (P〉0.05).The levels of SOD,GSH-PX,GSH,NO,NOS and EDFMD in H type hypertension group were all significantly lower than those in control group [(81 ± 19) IU/ml vs (96± 18) IU/ml,(161 ± 28) U/Lvs (174±27) U/L,(0.8±0.2) mmol/L vs (0.9±0.2) mmol/L,(72± 15) μmol/L vs(82 ± 14) μmol/L,(2.0±0.4) U/ml vs (2.7±0.4) U/ml,(9.3±0.9)% vs (13.7±0.8)%] (all P〈0.05),while MDA and Hcy in H type hypertension group were significantly higher than those in control group [(13.3 ± 0.8) μmol/L vs (7.6 ±0.6) μmol/L,(12.3 ±2.9) μmol/L vs(9.1 ±3.0) μmol/L] (both P 〈0.05).Conclusion Patients with H type hypertension have endothelial dysfunction and lipid peroxidation injury,which should be intervened actively.
