性激素和氧自由基与冠心病的相关性研究

为探讨性激素、氧自由基对心病（ＣＨＤ）发病的影响，检测绝经后女性ＣＨＤ患者（ｎ＝４４）和对照组（ｎ＝２２）血清雌二醇（Ｅ２）睾酮（Ｔ）、超氧化物坡化酶（ＳＯＤ）、丙二醛（ＭＤＡ）及血脂水平。结果表明：ＣＨＤ组血清Ｔ，ＭＤ坑于对照组，Ｅ２，Ｅ２／Ｔ和ＳＯＤ显著低于对照组；ＣＨＤ组血清Ｆ２与ＳＯＤ呈正相关，与ＭＤＡ呈负相关；尼尔雌醇替代治疗１２周后精ＳＯＤ及ＨＤＬ－Ｃ／ＴＣ显著升高，而血甭ＬＤＬ－Ｃ和

Roles of sex hormones and oxygen free radical in coronary heart disease]

To examine the roles of sex hormones and oxygen free radical(OFR) in coronary heart disease (CHD), the serum estradiol(E2), testosterone(T), SOD, MDA and lipid levels were measured in 44 postmenopausal women with CHD and 22 health women. Mean levels of T and MDA were significantly higher while mean levels of SOD and E2 were significantly lower in CHD group than those in control group. On relative analysis, there was a positive correlation between E2 and SOD, while a negative correlation was observed between T and MDA in CHD group. Eighteen postmenopausal women with CHD had been receiving nilestriol replacement therapy for 12 weeks. The serum SOD and HDL-C/TC levels increased significantly, but LDL-C and MDA decreased significantly. The overall data suggest that OFR plays an important role in CHD; Low E2 levels is a risk factor of CHD in postmenopausal women; Nilestriol replacement therapy can improve the metabolism of serum lipids and inhibit lipid peroxidation, therefore, it may be of benefit to postmenopausal women with CHD.
