Correlation of vascular endothelial function and coagulation factors with renal function and inflammatory factors in patients with diabetic nephropathy

Correlation of vascular endothelial function and coagulation factors with renal function and inflammatory factors in patients with diabetic nephropathy was analyzed. A total of 86 patients diagnosed with diabetes mellitus (DM) and admitted to the 89th Hospital of the People's Liberation Army (Weifang, China) from March 2014 to May 2017 were selected. Among them, 38 patients complicated with nephropathy were divided into the observation group and 48 patients without nephropathy into the control group. The general data of patients were collected, and the relevant biochemical indexes, vascular endothelial function, coagulation factors and renal function indicators and the levels of inflammatory factors were determined. In the observation group, the duration of DM was longer than that in the control group, and the levels of glycated hemoglobin (HbA1c), fasting plasma glucose (FPG) and fasting insulin (FINS), level of fibrinogen (FIB) were higher than those in the control group (p<0.05). Homocysteine (Hcy) and brachial artery blood flow in the observation group were higher than those in the control group. The levels of nitric oxide (NO) and flow-mediated dilation (FMD) were lower than those in the control group (p<0.05). Activated partial thromboplastin time (APTT) in the observation group was shorter than that in the control group (p<0.05). The levels of cystatin-C (Cys-C), serum creatinine (SCr), urea and β2-microglobulin, levels of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in peripheral serum in the observation group were greatly higher than those in the control group (p<0.05). It was concluded via the correlation analysis of vascular endothelial function and coagulation factor with renal function and inflammatory factors that SCr and CRP were negatively correlated with NO, and SCr and CRP were positively correlated with FIB. Serum inflammatory factors, coagulation function and vascular endothelial function are closely related to diabetic nephropathy, which are good reference indexes for the assessment of diabetic nephropathy.
