Abstract:
Objective To observe the effects of Huazhuo Granule on expression of phosphatidylinositol-3-kinase (PI-3K) and glucose transporter 4 (GLUT4) in skeletal muscle type 2 diabetes (T2DM) rats;To discuss its effects on activating signal path of PI-3K and GLUT4. Methods High-fat diet combined with low-dose streptozotocin intraperitoneal injection was used to establish T2DM rat models. The rats were randomly divided into blank group, Huazhuo Granule group, rosiglitazone group, and model group. Each treatment group was given relevant medicine for gavage. Model group and blank control group were given normal saline for gavage. The general state, weight, and food ration of rats were observed. After ten-week medicine intervention, 10%chloral hydrate was used for anesthesia to detect the levels of FBG, OGTT (2 h PG), and FINS. RT-PCR was used to detect the expressions of PI-3K and GLUT4 mRNA of rat skeletal muscle in all groups. Results Compared with model group, the levels of FBG, 2 h PG, and FINS decreased (P<0.05);the expressions of PI-3K and GLUT4 mRNA of rat skeletal muscle increased significantly (P<0.05). Conclusion Huazhuo Granule has the effects on increasing insulin sensitivity, which is related to activating insulin signal path of PI-3K and GLUT4 of skeletal muscle tissues.
