Abstract:
Objective To investigate the relationship between apolipoprotein (Apo) e4 allele and endothelium dependent arterial dilation in females with type 2 diabetes mellitus. Methods One hundred and one female type 2 diabetic patients without angiopathy, aged 40 71 years, and 95 healthy female individuals were selected. PCR/allele specific oligonucleotide probes were used to determine Apo e genotypes, and high resolution ultrasound was applied to measure brachial artery flow mediated endothelium dependent dilation and glyceryltrinitrate (GNT) mediated endothelium independent dilation. Results (1) In both diabetic patients and healthy individuals, the flow mediated endothelium dependent arterial dilation in subjects with e4/3 or e4/4 genotypes was (3.22?0.29)% and (3.78?0.34)% respectively, which were significantly lower than those in subjects with e2/2 or e3/2 genotypes 〔(3.96?0.33)% and (4.74?0.41)%, P
