ABSTRACT
Objective:to explore the mechanism of modified Tianwang Buxindan in improving abnormal glucose and lipid metabolism in mice with chronic sleep deprivation from the signal pathway of orexin A/ orexin receptor 1(OX1R). Method:The 50 6-week-old male C57BL/6 mice were randomly divided into blank group , model group , estazolam group and Tianwang Buxindan low and high dose groups ,for ten mice of each group. Except the blank group, rats were deprived of sleep for 8 weeks by the method of multi-platform water environment. In the last 4 weeks, Tianwang Buxindan (8.5,17 g·kg-1)and estazolam solution(9.1 mg·kg-1)were given to the stomach, and the blank group and the model group were fed with pure water of the same volume. The food intake and body weight of mice were measured twice a week, on the 49th day, blood samples were collected from the tail vein for glucose tolerance test (GTT),on the 52nd day for insulin tolerance test(ITT), was used to detect the expression of total cholesterol (TCH), triglyceride(TG)and free fatty acid(FFA)in serum, and enzyme-linked immunosorbent assay(ELISA)was used to detect the expression of orexin A in serum and hypothalamus. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR)and Western blot were used to detect the mRNA and protein expression of OX1R in hypothalamus. Result:After administration, the food intake of mice in each group was different, compared with the blank group, the body weight of model group was significantly reduced(P<0.05), the glucose tolerance was significantly abnormal, and the TCH, TG, FFA values were significantly increased(P<0.01). The expression of orexin A in serum and hypothalamus increased significantly(P<0.01), and the mRNA and protein expression levels of OX1R in hypothalamus increased significantly(P<0.01). Compared with the model group, the body weight of each group of Tianwang Buxindan was significantly increased(P<0.05), with better glucose tolerance and insulin sensitivity, TCH, TG, FFA values were significantly reduced(P<0.05,P<0.01), accompanied by serum and the expression of orexin A in the hypothalamus was significantly decreased(P<0.05,P<0.01), the mRNA and protein expression levels of OX1R were significantly decreased(P<0.05,P<0.01). Conclusion:Tianwang Buxindan can protect mice from abnormal glucose and lipid metabolism induced by chronic sleep deprivation, and its mechanism may be related to the down-regulation of orexin A/OX1R signal expression.
