RESUMO
Contrast induced nephropathy (CIN) is acute renal injury following administration of contrast media during angiographic or other medical procedures, which represents as the third cause of hospital-acquired renal failure. CIN is associated with prolonged hospital stay, increased health-care costs, and undesirable clinical outcome. The risk of CIN includes advanced age and diabetes mellitus. With the rapid development of iconography and the wide application of interventional techniques, the patients with CIN are increasing. The preventive measures of CIN include hydration, using appropriate contrast media, stopping nephrotoxic drugs, ischemic preconditioning, renal replacement therapy, and using appropriate drugs. In this paper, the current status and early prevention progress of CIN will be reviewed from three aspects of the high-risk factors, pathogenesis and prevention, aiming to provide guidance for the early prevention of CIN and explore new research directions.

RESUMO
OBJECTIVE:To explore the effects of early treatment with mouse nerve growth factor on the wound healing in aged patients with electric burn. METHODS:78 elderly patients with electric burn were divided into control group and observation group by random number table method,with 39 cases in each group. Control group was given routine method for electric burn, and observation group was additionally given Mouse nerve growth factor for injection 30 μg dissolved in 2 ml 0.9% Sodium chlo-ride injection within 24 h,im,qd,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. Clinical effica-cies of 2 groups were compared as well as VAS score before treatment,3,5,7 days after treatment. The survival rate of skin flaps and the rate of wound healing 3,5,7 days after treatment,the recovery of wound scar,the value of wound blood perfusion,the time of complete wound healing and the occurrence of ADR were also compared. RESULTS:The total effective rate of observation group(94.9%)was significantly higher than that of control group(66.7%),with statistical significance(P<0.05). 3,5,7 days after treatment,VAS score of observation group was significantly lower than that of control group,and the survival rate of skin flaps and the rate of wound healing were significantly higher than those of control group,with statistical significance(P<0.05). Af-ter treatment,VSS score of observation group was significantly lower than that of control group,while the value of wound blood perfusion was significantly higher than that of control group;the time of complete wound healing was significantly lower than that of control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Early treat-ment with mouse nerve growth factor for elderly patients with electric burns can effectively lower the VAS and VSS score,improve the survival rate of skin flaps and the rate of wound healing,increase the value of wound blood perfusion and shorten the time of complete wound healing with good clinical efficacy and safety.
