Immediately after admission, the urinary albumin excretion rate (UAER) of all groups were determined;automatic biochemical analyzer was used to determine renal function index levels, ELISA method was used to determine inflammatory factor levels, and RIA method was used to determine the oxidative stress index levels;Pearson test was used to analyze the correlation of UAER value with renal function, inflammatory response and oxidative stress response in patients with DN.Results:Differences in UAER value as well as renal function index, inflammatory response index and oxidative stress index levels were statistically significant among three groups of subjects. UAER value as well as BUN, Scr, CysC,β2-MG, IL-6, hs-CRP, TNF- , MDA and AOPP levels of early DN group and middle-advanced DN group were higher than those of normal control group while T-AOC and SOD levels were lower than those of normal control group;UAER value as well as BUN, Scr, CysC,β2-MG, IL-6, hs-CRP, TNF- , MDA and AOPP levels of middle-advanced DN group was higher than those of early DN group while T-AOC and SOD levels were lower than those of early DN group;UAER value in patients with DN was correlated with renal function, inflammatory response and oxidative stress.Conclusion:UAER value can directly reflect the renal injury, inflammation and oxidative stress in patients with DN, and be the reliable means for early disease diagnosis and treatment guidance.展开更多

The aim of this study was to investigate the correlation between the urinary albumin excretion rate and the incidence and severity of coronary heart disease in elderly type 2 diabetes mellitus patients. Methods A total of 612 hospitalized type 2 diabetes mellitus patients aged 60 years or older, who were given coronary angiography for diagnosis of possible coronary heart disease, participated. Their urinary albumin excretion rate was measured, and the severity of coronary artery stenosis was quantified with the Gensini scoring system to analyze the incidence of coronary heart disease and the severity of coronary artery stenosis. The optimal urinary albumin excretion rate predictive value for coronary heart disease incidence in elderly type 2 diabetes mellitus patients was determined. Results The incidence of coronary heart disease, the number of patients with coronary vascular disease and the Gensini scores were significantly different between the microalbuminuria group and the normal atbuminuria group （P 〈0.05）. The urinary albumin excretion rate was independently correlated with the occurrence of coronary heart disease in elderly type 2 diabetes mellitus patients （odds ratio （OR） =1.058, P 〈0.0001,95% confidence interval （CI）： 1.036-1.080）. Urinary albumin excretion rate and the Gensini score were independently correlated in elderly type 2 diabetes mellitus patients （β=0.476, P 〈0.0001）. The best predictive value of urinary albumin excretion rate was 10.45 tJg/min for elderly type 2 diabetes mellitus patients. The area under the curve was 0.764, with a sensitivity and specificity of 70.0% and 72.2%, respectively. Conclusions The occurrence of coronary heart disease in elderly type 2 diabetes mellitus patients with microalbuminuria was higher than that in patients with normal albuminuria, and the severity of the disease also increased in patients with microalbuminuria. In elderly type 2 diabetes mellitus patients, urinary albumin excretion rate was positively correlated with the incidence and severity of coronary heart disease and was also an independent factor contributing to coronary heart disease.展开更多
