OBJECTIVE To investigate the effects of compliance and periodic telephone counselling by a pharmacist on mortality in patients receiving polypharmacy. DESIGN Two year randomised controlled trial. SETTING Hospital medical clinic. PARTICIPANTS 502 of 1011 patients receiving five or more drugs for chronic disease found to be non-compliant at the(More)
OBJECTIVE The insertion/deletion (I/D) polymorphism of the ACE gene has been reported to be associated with diabetic microvascular or macrovascular complications. The aim of the present study was to investigate the prognostic effect of I/D polymorphism on renal and cardiovascular clinical outcomes in Chinese patients with type 2 diabetes. RESEARCH DESIGN(More)
This review focuses on the efficacy and safety of Chinese medicine in the treatment of type-2 diabetes. Included were 84 controlled clinical studies of type-2 diabetes treated with Chinese medicine for at least 1 month. Reported outcomes were: symptom relief; improvement in glycemia, insulin resistance and secondary failure, and adverse events. Symptom(More)
OBJECTIVE International guidelines recommend optimal control of risk factors in diabetes to prevent cardiovascular events. We examined risk associations between achieving treatment targets for glycemia, blood pressure and lipid control, and other risk factors on subsequent cardiovascular events in Chinese patients with type 2 diabetes.

Berberine has been shown to have insulin-sensitizing effect, but the molecular mechanism underlying remains elusive. In this work, we investigated the effect of berberine on insulin-induced signal transduction and glucose uptake in both insulin-sensitive and insulin-resistant rat skeletal muscle cells. Berberine increased the activity of AMPK and PKCzeta(More)
We assessed the effects of angiotensin-converting enzyme (ACE) inhibition on survival and cardiorenal outcomes in a consecutive cohort of Chinese type 2 diabetic patients with varying degree of albuminuria, ranging from normoalbuminuria to macroalbuminuria. A total of 3773 consecutive Chinese type 2 diabetic patients were followed prospectively for a mean(More)
BACKGROUND Diabetic nephropathy represents a heterogeneous group of renal pathologies that may be associated with genetic susceptibility. There have been clinical reports on the risk association of diabetic nephropathy with an apolipoprotein E (ApoE) exon 4 polymorphism although its correlations with renal histopathological changes have not been explored.(More)
OBJECTIVE We report the independent risk association of type 2 diabetic nephropathy with the z-2 allele of the 5'-(CA)(n) microsatellite and C-106T promoter polymorphisms of the aldose reductase gene (ALR2) using a case-control design. In this expanded cohort, we examined their predictive roles on new onset of cardiorenal complications using a prospective(More)
Both microtubule and actin are required for insulin-induced glucose uptake. However, the roles of these two cytoskeletons and their relationship in insulin action still remain unclear. In this work, we examined the morphological change of microtubule/actin and their involvement in insulin signal transduction using rat skeletal muscle cells. Insulin rapidly(More)
T he risk of type 2 diabetes in Mexican -Americans is almost twice that of non-Hispanic Caucasians (1). Mexican-Americans are also, in general, more likely to have insulin resistance, impaired fasting glucose, and impaired glucose tolerance than non-Hispanic Caucasians (1,2). Given these increased risks of type 2 diabetes in the Mexican-American population(More)
