Abstract

Our aim was to explore the effects of dietary and behavior interventions on lipometabolism caused by an unhealthy high-fat diet and the best method to rebuild lipid homeostasis of this lifestyle. Apart from normal diet rats, 34 rats were fed with high-fat emulsion for 4 weeks and then intervened for another 4 weeks. Eight of them were classified into high-fat control group, and 9 were sorted into high-fat diet with rice vinegar group. Meanwhile, 10 were put into high-fat diet in swimming group, and 7 were just for refeeding normal diet group. Then, the data of body weight was recorded and analyzed. Indexes of serum samples were tested by kits. AMPK, HNF1, and CTRP6 in pancreas, liver, cardiac, and epididymis adipose tissues were detected by western blot. According to our experiments, swimming and refeeding groups reflected a better regulation on lipid homeostasis mainly by upregulating the expression of pancreas AMPK. To be more specific, the refeeding rats showed lower T-CHO ( < 0.001) and LDL-C ( < 0.05), but higher weight gain ( < 0.001), insulin level ( < 0.01), and pancreas AMPK ( < 0.01) than high-fat control rats. Compared with rats intervened by swimming or rice vinegar, they showed higher weight gain ( < 0.001), insulin level ( < 0.01), and HNF1, but lower of CTRP6. In summary, refeeding diet functioned better in regulating the lipometabolic level after high-fat diet. Whatever approach mentioned above we adopted to intervene, the best policy to keep the balance of lipid homeostasis is to maintain a healthy diet.

摘要

我们的目的是探索饮食和行为干预对不健康高脂肪饮食引起的脂代谢紊乱的影响,以及重建这种生活方式脂质稳态的最佳方法。除了正常饮食的大鼠外,还有 34 只大鼠用高脂肪乳剂喂养 4 周,然后再干预 4 周。其中 8 只分为高脂肪对照组,9 只分为高果糖醋饮食组。同时,将 10 只大鼠放入游泳组,7 只大鼠重新给予正常饮食组。然后记录并分析体重数据。试剂盒检测血清样本指标。通过 Western blot 检测胰腺、肝脏、心脏和附睾脂肪组织中 AMPK、HNF1 和 CTRP6 的表达。根据我们的实验,游泳和重新喂养组主要通过上调胰腺 AMPK 的表达来更好地调节脂质稳态。更具体地说,重新喂养的大鼠表现出更低的 T-CHO(<0.001)和 LDL-C(<0.05),但更高的体重增加(<0.001)、胰岛素水平(<0.01)和胰腺 AMPK(<0.01)比高脂肪对照组大鼠。与游泳或醋干预的大鼠相比,它们表现出更高的体重增加(<0.001)、胰岛素水平(<0.01)和 HNF1,但 CTRP6 更低。总之,重新喂养饮食在调节高脂肪饮食后的脂代谢水平方面效果更好。无论采用哪种干预方法,保持健康饮食是维持脂质稳态平衡的最佳策略。
