* To investigate the etiology, epidemiology and prognostic factors of acute kidney injury. * To find out risk factors that relate with the prognosis of acute kidney injury,focusing on inflammation, oxidative stress and nutritional status. * To study on the relationship between gene polymorphism and prognosis of acute kidney injury.
1. to investigate the relationship between preexisting malnutrition and adverse outcomes in patients with AKI \- Several nutritional assessment methods such as anthropometric, clinical and biochemical evaluations have been used; however, no single indicator is considered to be a "gold standard." 2. to evaluate the association of serum nutritional variables and prognosis of acute kidney injury 3. Given the different half-lives of serum nutritional markers, we hypothesized that the utility of serum nutritional variables as prognostic predictors may differ in early death (\<7 days) and late death (\>7 days, \<28 days) patients.
