OBJECTIVE In this study, circulating serum betatrophin levels were quantitated and their relationships with insulin resistance (IR) and other metabolic parameters in Chinese subjects with varying degrees of obesity and glucose tolerance were examined. METHODS Serum betatrophin levels were determined using ELISA in 60 subjects with normal glucose tolerance(More)
BACKGROUND Low vitamin D levels can be associated with albuminuria, and vitamin D analogs are effective anti-proteinuric agents. The aim of this study was to investigate differences in vitamin D levels between those with micro- and those with macroalbuminuria, and to determine whether low dose cholecalciferol increases vitamin D levels and ameliorates(More)
The overproduction of mitochondrial reactive oxygen species (ROS) plays a key role in the pathogenesis of diabetic nephropathy (DN). However, the underlying molecular mechanism remains unclear. Our aim was to investigate the role of PGC-1α in the pathogenesis of DN. Rat glomerular mesangial cells (RMCs) were incubated in normal or high glucose medium with(More)
OBJECTIVE To test the hypothesis that a microalbuminuria (MA) threshold can help predict the risk for the development of diabetic retinopathy (DR) in type 2 diabetes mellitus (T2DM)_ patients. DESIGN We conducted a cross-sectional study of 4739 subjects with T2DM and a prospective study of 297 subjects with T2DM in China respectively. METHODS Clinical(More)
AIMS This cross-sectional study aimed to determine the prevalence and associated risk factors of chronic kidney disease (CKD) in Chinese type 2 diabetic patients. METHODS A total of 3301 patients with type 2 diabetes were included in this study. Anthropometric parameters and biochemical indices were measured. The main outcome measures were detection of(More)
OBJECTIVE Hyperfiltration confers an increased risk of diabetic nephropathy. Early detection can ensure timely intervention and improved treatment outcomes. Because GFR is known to be affected by hyperglycemia, the aim of this study was to compare the influence of hyperglycemia on GFR estimations calculated by the CKD-EPI equation, the CG equation, and the(More)
BACKGROUND There is increasing evidence that serum betatrophin levels, a hormone derived from adipose tissue and liver, are elevated in type 2 diabetes (T2D). OBJECTIVE To investigate the relationships among betatrophin and metabolic control, insulin resistance, and pancreatic β-cell function in obese Chinese patients with T2D who underwent Roux-en-Y(More)
A growing body of evidence suggests that NAFLD is associated with an increased risk of incident CVD events both in patients without diabetes and in those with type 2 diabetes (T2DM). However, no published data are available regarding the association between NAFLD and C-IMT in T1DM. A total of 722 patients (371 men) with T1DM were included in this(More)
BACKGROUND Diabetic nephropathy is one of the major microvascular complications of diabetes. We investigated the association between urinary Smad3 (usmad3) levels, glomerular hyperfiltration, and the development of nephropathy in patients with type 2 diabetes mellitus (T2DM). METHODS The usmad3 level was determined by enzyme-linked immunosorbent assay in(More)
BACKGROUND Recent studies highlight a negative association between total bilirubin concentrations and albuminuria in patients with type 2 diabetes mellitus. Our study evaluated the relationship between bilirubin concentrations and the prevalence of diabetic nephropathy (DN) in Chinese patients with type 1 diabetes mellitus (T1DM). METHODS A total of 258(More)
