Abstract
Proton nuclear magnetic resonance(~1H-NMR) is used to investigate the effect of Renshenjian Decoction on serum and urine metabolism of type 2 diabetic rats with insulin resistance induced by high-sugar and high-fat diet combined with low-dose streptozotocin(STZ). After the successful establishment of the insulin resistance model of type 2 diabetes, administration for 35 days, the serum and urine of rats were taken. Once the ~1H-NMR data have been collected and processed, PCA and OPLS-DA were used to analyze them. The results show that: compared with the blank group, the contents of methionine, taurine, α-glucose and β-glucose in the serum of the model group increased significantly(P<0.001), while the contents of 3-hydroxybutyric acid, lactic acid and unsaturated fatty acids decreased significantly(P<0.01). In the model group, the contents of trimethylamine oxide, glycine, α-glucose, β-glucose, taurine and phosphocholine in urine increased significantly(P<0.05), while the contents of creatine, lactic acid, acetic acid and citric acid decreased significantly(P<0.05). Compared with the model group, the contents of 3-hydroxybutyric acid and unsaturated fatty acids in serum of rats in the treatment group increased significantly(P<0.05), while the contents of taurine, α-glucose and β-glucose decreased significantly(P<0.01). In the treatment group, the contents of lactic acid, taurine and creatine in urine increased significantly(P<0.05), while the contents of trimethylamine oxide, glycine, α-glucose, β-glucose and phosphocholine decreased significantly(P<0.01). The results show that Renshenjian Decoction can regulate metabolic disorder and promote the metabolic phenotype to return to the normal range. It displayed therapeutic effect on type 2 diabetic rats with insulin resistance and provided a certain scientific basis for the biological basic research of Renshenjian Decoction by improving insulin resistance in diabetes mellitus.
