ABSTRACT
Objective To observe the effects of modified Liujunzi Decoction on improving isletβ-cell function of patients with the syndrome of spleen-deficiency and phlegm-stagnation of type2 diabetes mellitus.Methods Totally 72 patients were selected and divided into treatment group and control group randomly, with 36 cases in each group. Both groups were under diet adjustment and appropriate exercise and were given metformin hydrochloricle tablets, 0.5 g each time (1.0 g each time after 2 weeks), twice a day; acarbose, 50 mg each time, three times a day. The treatment group was given modified Liujunzi Decoction additionally, 200 mL each time, three times a day, orally. The course of treatment of the two groups was three months. Blood glucose, C peptide, INS, HbA1c, HOMA-IR, HOMA-β andΔI30/ΔG30 after 30 minutes of glucagon loading was recorded.Results Compared with before treatment, FBG, 30 min PBG, 2h PBG, HbA1c, FINS, fasting C-peptide, and HOMA-IR decreased in both groups, and the 30 min INS, 30 min C peptide, andΔI30/ΔG30 increased in the treatment group, with statistical significance (P<0.05). After treatment, there was statistical significance in FBG, 30 min PBG, 2 h PBG, HbA1c, fasting C-peptide, FINS, 30 min INS, 30 min C peptide, HOMA-IR, andΔI30/ΔG30 between the two groups (P<0.05).Conclusion Modified Liujunzi Decoction combined with Western medicine can better improve isletβ-cell function of patients with the syndrome of spleen-deficiency and phlegm-stagnation of type2 diabetes mellitus than Western medicine merely.
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.
