Abstract

In this study, we innovatively propose a fucoidan mixed with traditional Chinese medicine formula (FCM) and evaluate its effects on hyperglycaemia and diabetic nephropathy in a type II diabetes mellitus Wistar rat model. After treatment with FCM for 8 weeks, the blood glucose, insulin resistance, serum lipid and antioxidant stress levels were significantly decreased (P < 0.05 or P < 0.01, vs. negative group). Via gene expression analysis, we found that three genes (InsR, GCK and GLUT-2) in the glucose metabolism pathway were significantly increased (P < 0.01, vs. negative group) in the FCM-treated groups and play important roles in hypoglycaemic activity. Moreover, FCM treatments alleviated (P < 0.01, vs. negative group) the urine protein, urine creatinine and pathological changes in the kidneys, producing significant improvements in renal function and structure. In summary, FCM exerts protective effects in diabetic rats and could be used in medicinal treatment for diabetes mellitus and its complications.
