Abstract:
AIM To observe the effects of Huangdi Anxiao Capsules (Puerariae lobatae Radix,Eriobotryae Folium,Notoginseng Radix et Rhizoma,etc.) on blood glucose and insulin resistance in GK rats with type 2 diabetes mellitus (T2DM) and its possible mechanism of action.METHODS GK rats with T2DM included in the experiment were randomly divided into model group,rosiglitazone (1.44 mg/kg) group,Shenqi Jiangtang Granules (1.08 g/kg) group,Huangdi Anxiao Capsules high,medium and low (12,6,3 g/kg) group and normal control group of Wistar rats.After six weeks of consecutive administration,fasting blood glucose (FBG),serum insulin (FINS),fasting plasma glucose (FPG),and insulin resistance index (HOMA-IR) were measured in all groups.Serum biochemical indexes of (TG,TC,HDL-C,LDL-C),glycosylated hemoglobin (HbA1c),glucagon-like peptide (GLP-1) and insulin-like growth factor (IGF-1) were measured.The pancreatic tissue was obtained by routine paraffin embedding and HE staining to observe the pathological changes.RESULTS Compared with the normal group,FBG,FPG,FINS,HOMA-IR,TG,TC,HDL-C,LDL-C and HbA1c of the model group were significantly higher (P ＜0.01),and GLP-1 and IGF-1 expressions were markedly decreased (P ＜ 0.01).Compared with the model group,the levels of FBG,FPG,FINS,HOMA-IR,TG,TC,HDL-C,LDL-C and HbA1 c in Huangdi Anxiao Capsules high-,medium-and low-dose group were significantly decreased (P ＜ 0.05,P ＜0.01);GLP-1 and IGF-1 expressions were markedly increased (P ＜0.05,P ＜0.01),compared with the model group,the structure changes of pancreatic tissue in Huangdi Anxiao Capsules high-,medium-and low-dose groups largely reduced.CONCLUSION Huangdi Anxiao Capsules can reduce GK rats fasting blood glucose,insulin resistance,and its mechanism may be related to promoting the emergence and proliferation of pancreatic islet cells,improving the function of islet beta cells,and increasing insulin secretion.
