【摘要】 目的 观察冠心病合并高甘油三酯(TG),低高密度脂蛋白-胆固醇(HDL-C)血 症患者应用非诺贝特治疗后,其血清对前列环素(PGI2)生物活性的影响。方法 选择冠 心病组和正常组各20例,以PGI2对二磷酸腺苷(ADP)诱导的血小板聚集的抑制率作为PGI2 生物活性的指标,在冠心病组服用非诺贝特前及一个月后,比较两组患者的血清对PGI2生 物活性的影响及与血脂的关系。结果 实验发现,在应用非诺贝特治疗前,冠心病组血清 对PGI2生物活性的稳定作用明显低于正常组(P〈0.01)。应用非诺贝特治疗1个月后,冠心 病组的血TG水平显著降低(P〈0.001),血HDL-C水平显著升高(P〈0.01); 同时,冠心病组 血清对PGI2的稳定作用与正常组相比不再有显著性差异(P>0.05)。结论 本实验进一步证 实了HDL-C对PGI2的保护作用。因低HDL-C血症是冠心病的危险因子,因而其降低PGI2生物 活性从而增加血小板聚集很可能是其作用机制的一部分。经过调脂治疗后,升高血HDL-C水 平,恢复HDL-C对PGI2的保护作用对防止粥样斑块破裂和减少急性冠状动脉综合征的发生可 能起重要作用。 【关键词】 非诺贝特 脂蛋白类,HDL 甘油三酯类 冠状动脉疾病 依前列醇
Influence of fenofibrate on PGI2 stabilizing effect of sera from CAD patients with low HDL and hypertriglyceridemia Li Jingdong, Dai Guizhu, Fong Zongchen, et al. Institute of Cardiovascular Disease, Tongji Medical University, Wuhan 430022 【Abstract】 Objective To investigate the influence of PGI2 stabilizing effect of sera from coronary artery disease (CAD) patients with hypertriglyceridemia and low HDL before and after fenofibrate treatment. Methods Twenty CAD patients and 20 healthy individuals were enrolled. The inhibitory rate of PGI2 on ADP-induced platelet aggregation was used as an index of PGI2 biological activity. All CAD patients were given fenofibrate 300 mg daily for one month. The relationship between PGI2 stabilizing effect and blood lipids were compared before and after the treatment. Results Before treatment, the stabilizing effect of serum on PGI2 activity decreased significantly in the CAD group as comparing with that of the control group (P〈0.01). One month after the treatment, HDL level in the CAD group increased significantly (P〈0.01), [1] [2] [3] 下一页 上一个医学论文: 氨氯地平和培哚普利联合治疗对高血压病患者肾功能的影响 下一个医学论文: 实验性病毒性心肌炎病程中穿孔素表达水平的变化及其与心肌损害的关系
