    摘要:

    目的 旨在建立一种实用的动物慢性代谢疾病模型,探讨高尿酸血症与糖脂代谢的相关性,以及其病理损伤机制。方法 采用高脂高次黄嘌呤饮食+氧嗪酸钾联合造模,检测鹌鹑血清尿酸和甘油三酯动态含量变化,并在实验结束后测定血清中各相关指标,并对肝、肾、主动脉进行病理检测。结果 高脂高次黄嘌呤饲料+氧嗪酸钾诱导可以明显升高鹌鹑血清尿酸和甘油三酯含量。糖耐量实验表明,联合造模组鹌鹑血糖峰值较高,血糖变化曲线下面积均大于其他各组,胰岛素水平也明显较其他组高。联合造模组还能升高血清谷草转氨酶、谷丙转氨酶活力及尿素氮、肌酐含量,对肝脏、主动脉和肾脏具有明显的损伤作用,这些损伤作用能被苯扎贝特和非布索坦不同程度缓解。结论 高脂高次黄嘌呤食饵+氧嗪酸钾联合诱导可以建立一种简便、稳定、持久的动物慢性代谢疾病模型。

    Abstract:

    Objective To establish a practical animal model of chronic metabolic syndrome (MS) and to investigate the correlation and pathological mechanism between hyperuricemia and glucose/lipid metabolism. Methods High fat purine diet + oteracil potassium were used to establish the MS model. Quail serum uric acid and triglyceride were tested every one/two weeks and other parameters were determined at the end of the procedure along with histopathology examination. Results Uric acid and triglyceride levels in serum were markedly enhanced by the long-term stimulation of high fat purine diet + oteracil potassium. Glucose tolerance test showed that the peak value of glucose and the area under curve in model group were higher than the others, as well as the insulin levels. Meanwhile, the modeling agents increased aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine and induced liver, kidney and artery injuries. These injuries were partially alleviated by bezafibrate or febuxostat. Conclusions The results of the present study suggest that high fat purine diet + oteracil potassium could induce a simple, stable and durable animal model of chronic metabolic disorders.
