摘　　要：目的探讨NUCB2/Nesfatin-1在饮食诱导肥胖(DIO)大鼠下丘脑中的表达水平,为糖脂代谢神经调节机制的深入研究提供实验依据。方法通过高能饲料喂养建立高血糖高血脂大鼠模型,采用免疫组织化学方法检测下丘脑NUCB2/Nesfatin-1表达水平。结果 1NUCB2/Nesfatin-1在实验组大鼠下丘脑表达的阳性率为43.33%,明显低于对照组的80.00%(P<0.05)。2 NUCB2/Nesfatin-1在实验组大鼠下丘脑的表达强度积分为2.159±0.918,对照组表达积分为3.683±1.250(P<0.01)。结论 NUCB2/Nesfatin-1在饮食诱导肥胖(DIO)大鼠下丘脑的表达水平明显降低,提示NUCB2/Nesfatin-1可能在糖脂代谢神经调节中具有重要作用。Objective To explore the NUCB2/Nesfatin- 1 expression level in hypothalamus of diet induced obesity （DIO） rats, and to provide experimental basis for the mechanism of nerve regulation by glucolipid metabolism. Methods To setting up high glucose and lipid rat model by high-energy feed, using immunohistochemical method to detect the hypothalamus NUCB2/Nesfatin-1 expression level. Results （1）NUCB2/Nesfatin-1 expression positive rate was 43.33% in the hypothalamus of the experimental group, which was significantly lower than that （80.00%） in the control group （P〈0.05）. （2） NUCB2/Nesfatin- 1 expression strength score was 2.159±0.918 in the hypothalamus in the experimental group, and was 3.683± 1.250 in the control group （P〈0.01）. Conclusion NUCB2/Nesfatin-1 expression level was decreased obviously in the hypothalamus of diet induced obesity rats, suggesting NUCB2/Nesfatin- I may play an important role in regulating glucolipid metabolism.
