ABSTRACT Objective:To investigate the preventive effect of probucol on contrast induced acute kidney injury (CIAKI) among patients with coronary artery disease complicated with diabetes undergoing percutaneous coronary intervention (PCI). Methods:92 cases of patients with diabetes and coronary artery disease admitted for elective PCI in our hospital were divided randomly into control group (46 cases, receiving hydration therapy) and intervention group (46 cases, receiving additional probucol). The changes in inflammation, oxidative stress, endothelial function, renal function, the incidences of CIAKI and prognosis were compared in two groups. Results:The levels of IL 18, NGAL, KIM 1, SOD increased dramatically and MDA, NO, NOS, ET 1 decreased after PCI in the two groups (P<0.05); The levels of IL 18, NGAL, KIM 1, MDA and ET 1 after PCI in intervention group were significantly lower than those in the control group (P<0.05), and the levels of SOD, NO and NOS were significantly higher than those in the control group (P<0.05). The levels of SCr, β2 MG, CysC, BUN increased (P<0.05) and the level of Ccr showed no significant change (P>0.05) after PCI in the control group; The levels of SCr, β2 MG, CysC, BUN had no obvious changes after PCI in intervention group (P>0.05), and Ccr increased after treatment (P<0.05). Compared with the control group, the levels of SCr, β2 MG, CysC, BUN were significantly lower (P<0.05) and the Ccr were significantly higher in the intervention group (P<0.05). The incidence of CIAKI and poor prognosis in the intervention group was significantly lower than that in the control group (P<0.05). Conclusion:Probucol had a satisfactory effect on the prevention of CIAKI among the patients with diabetes and coronary artery disease, and on inhibiting inflammation and oxidative stress, the protection of vascular endothelium and renal function,improving the prognosis. |
