轻度高血压患者应用西拉普利(cilazapril)或阿替洛
尔(atenolo1)药物治疗6月后发现:西拉普利组血
HGF水平下降,而阿替洛尔组血HGF水平无明显
改变.两研究结果不一致,故具体机制有待进一步
研究.

体质量过大女性做中等量阻力运动对血管的好处 血管内皮功能障碍是动脉粥样硬化心血管病 (CVD)的首发机制.有氧运动能改善血管功能,减 少CVD死亡率和病残率,但阻力运动效果如何还 不是很清楚(MedSciSportSociety,2006,38:1558— 1564).该文研究目的在于检查1年阻力运动(RT) 对体质量过重,但还算健康的人的血管功能有什么 影响.3O名(15名对照组,15名RT组),指过重妇 女(BMI>25kg/m.).年龄24,44岁.在RT锻 ?

炼1年前后用超声波检查颈动脉与肱动脉检查血管 功能,体内脂肪肌肉构成,BP,空腹血脂,血糖.结 果:RT组在1年阻力运动后,每次对抗最大阻力明 显增加(P<0.05),肌肉组织明显增加(P一0.04), 但BP,空腹血脂,血糖,胰岛素水平无变化,颈动脉 内膜一中膜厚度无变化,表示血管内皮功能的血流 介导的血管扩张(FMD)峰值明显增加(P<0.05).
结论:阻力运动能改善过重妇女的肱动脉内皮功能. 789n
