摘要: 目的 观察噻唑烷二酮类药物吡格列酮对心肌肥厚大鼠心肌炎性细胞因子表达的影响, 探讨此类药物的抗炎作用以及对心肌肥厚的影响。 方法 通过不完全结扎大鼠腹主动脉, 引起压力负荷增加,导致左心室心肌肥厚, 从术前1 周起灌胃给予吡格列酮(20 mg·kg-1 ·d-1) 直至术后4 周, 处死动物, 计算心脏重 体重的值, 分别用RT-PCR 法和免疫组化法测定心肌炎性细胞因子的mRNA 和蛋白质的表达。 结果 压力负荷增加引起大鼠心肌肥厚时, 心肌炎性细胞因子表达增加, 应用吡格列酮治疗, 可以抑制心肌肥厚大鼠心肌炎性细胞因子的表达, 同时减轻压力负荷升高引起的大鼠心脏重 体重值。 结论 吡格列酮可能通过抑制炎性细胞因子的表达抑制压力负荷升高引起的心肌肥厚。

Abstract: AIM: To examine the effects of pioglitazone, an agonist of peroxisome proliferator-activated receptor γon the expression of proinflammatory cytokine in cardiac hypertrophic rats, and to examine the anti-inflammatory activities of this drug. METHODS: Hypertrophic cells were produced by abdominal aortic banding.Pioglitazone(20 mg·kg-1·d-1) was given orally 1 week before operation and continued till 4 weeks after operation, then the rats were killed, the heart was excised and weighed, and the mRNA expression of interleukin-1β and cardiotropin-1 were examined by RT-PCR.The protein of the two cytokines was examined by immunohistochemical analysis. RESULTS: Pioglitazone reduced the mRNA and protein expression of the two proinflammatory cytokines and inhibited the pressure overload-induced increase in the heart weight-to-body weight ratio. CONCLUSION: Pioglitazone may regulate cardiac hypertrophy through inhibiting the expression of proinflammatory cytokines.

Key words: peroxisome proliferator-activated receptor, cardiac hypertrophy, cytokine, thiazolidinedione, pioglitazone
