OBJECTIVE To investigate the effects of traditional Chinese compound recipe Yiqi Zengmin (YQZM) formula on expression of glucose transporter 4 (GLUT4) in skeletal muscle of rats with type 2 diabetes induced by high-fat diet combined with low-dose-streptozotocin injection. METHODS Fifty male rats were randomly divided into two groups: model group fed with high-fat diet (n=40) and control group (n=10). After 4-week feed of high-fat diet, the rats of the model group were injected with streptozotocin at a dose of 35 mg/kg. Rats with plasma glucose over 16.67 mmol/L were randomly divided into 4 groups: diabetic model group, YQZM group, rosiglitazone group and losartan group and were treated with water, YQZM, rosiglitazone or losartan respectively by oral administration for 8 weeks. The expression of GLUT4 protein in the cytoplasm and the plasma membrane of isolated rats' skeletal muscles were detected by Western blotting. RESULTS The expression of GLUT4 in the plasma membrane was more than that in the cytoplasm in skeletal muscle tissues of the normal rats, while the expression of GLUT-4 in the plasma membrane was less than that in the cytoplasm in skeletal muscle tissues of the type 2 diabetic rats. YQZM formula enhanced GLUT4 translocation from the cytoplasm to the plasma membrane in skeletal muscle tissues, similar to rosiglitazone. CONCLUSIONS YQZM formula can enhance GLUT4 translocation from the cytoplasm to the plasma membrane in skeletal muscle tissues, and displays the insulin sensitization characteristic of rosiglitazone.

D003924	Diabetes Mellitus, Type 2	A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

D051275	Glucose Transporter Type 4	A glucose transport protein found in mature MUSCLE CELLS and ADIPOCYTES. It promotes transport of glucose from the BLOOD into target TISSUES. The inactive form of the protein is localized in CYTOPLASMIC VESICLES. In response to INSULIN, it is translocated to the PLASMA MEMBRANE where it facilitates glucose uptake.
