摘要 目的:观察脂蛋白酯酶活化剂艾溴利平(ibrolipim,别名NO-1886)对高脂高蔗糖高胆固醇喂养的巴马小型猪餐后三酰甘油代谢的影响。方法:将10头巴马小型猪随机分为正常对照组和高脂高糖高胆固醇喂养组,分别用正常饲料、高脂高糖高胆固醇饲料喂养5个月,每个月末监测其空腹血糖、血清总胆固醇、高密度脂蛋白胆固醇、三酰甘油和游离脂肪酸水平。第5个月末从2组动物中分别随机选取3头进行脂肪耐量试验,分别经胃管给予以下4种处理:生理氯化钠溶液(10mL·kg^-1),20%脂肪乳剂(10mL·kg^-1),20%脂肪乳剂+艾溴利平(0.3g·kg^-1),20%脂肪乳剂+艾溴利平(1.0g·kg^-1)。测定0—8h内每小时血清三酰甘油和游离脂肪酸水平。结果:高脂高蔗糖高胆固醇喂养的小型猪血糖和血脂各项指标均显著升高。艾溴利平可以降低正常对照组脂负荷后血清三酰甘油和游离脂肪酸,呈一定剂量依赖,对高脂高糖高胆固醇喂养组的三酰甘油和游离脂肪酸亦有降低作用,但是降低幅度低于正常对照组。结论:艾溴利平可以降低正常对照组和高脂高蔗糖高胆固醇组脂负荷后血清三酰甘油和游离脂肪酸水平。 Objective: To evaluate whether ibrolipim (NO-1886), a lipoprotein lipase (LPL) activator, improves the postprandial lipid metabolism. Methods: Fifteen male Bama minipigs were randomized to supplement normal diets or high-fat/high-sucrose/high-cholesterol diets (HFSCD) for 5 months. At the end of each month, the blood samples were collected from the orbital sinus of the minipigs to measure levels of fasting glucose, free fatty acids ( FFAs), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG). At the end of the 5th month, a fat tolerance test was conducted as followed: the 3 minipigs in each group were intragastrically administered with one of four feeding regimens: normal saline ( 10 mL·kg^-1 ), fat (Intralipid, 10 mL·kg^-1 ), fat ( 10 mL·kg^-1 ) plus NO-1886 (0.3 g· kg^-1 ), or fat (20 mL· kg^-1 ) plus NO-1886 ( 1.0 g· kg^-1 ). The blood samples were collected pre- and every hour for 8 hours post-gavaging to measure serum TG and FFAs levels. Results:The ibrolipim-treated minipigs showed decreases of postprandial TG and free fatty acids levels in a dose-dependent manner. The reduction rate in the HFSCD groups was less than in the normal diet group. Conclusion:Ibrolipim (NO-1886) reduced plasma triglycerides and free fatty acids by activiation of lipoprotein lipase in the Bama minpigs.
