Associaton of polymorphism of endothelial nitric oxide synthase gene with essential hypertension and type 2 diabetes mellitus / 中华内分泌代谢杂志

ABSTRACT

Objective To investigate the association of the polymorphism of endothelial nitric oxide synthase (eNOS) gene 27bp variable number of tandem repeats (VNTR) with essential hypertension (EH) and type 2 diabetes mellitus (DM) in Chinese population. Methods (1) Genotypes were determined by polymerase chain reaction (PCR)-agarose gel electrophoresis. (2) Fasting serum nitric oxide metabolites (NOx) were measured by nitrate reductase. (3) During oral glucose tolerance test (OGTT) serum immunoreactive insulin (IRI) and C peptide (CP) were measured by radioimmunoassay. Results (1) The frequenciesofaalleleinEHandtype2DMgroupwere significantly higher than that in control group (0.109 vs 0.051; 0.129vs 0.051, P
