Objective:To investigate the diagnostic value of serum CystatinC (CysC)and urinary neutrophil gelatinase associated
lipocalin(NGAL)of acute kidney injury(AKI)in patients with paraquat poisoning.Methods:Selected 300 cases of patients with paraquat
poisoning who treated in our hospital from March 2011 to March 2015 as the case group, and 150 cases of healthy physical examination
subjects as the control group, case group was divided into AKI group and non AKI group according to whether occurrence of AKI,with
150 patients in each group, detected the NGAL by enzyme linked immunosorbent assay, and detected the serumcreatinine (Scr) level by
Muscle ammonia oxidase method, and detected CysC level by immune transmission turbidity method, observed the change of expression
level of CysC, NGAL in all objects at 15 min, 2 h, 4 h, 8 h, 12 h, 24 h, 48 h, 3 d, 5 d, 7 d after admission.Results:The Scr levels of AKI
group and non AKI group were significantly higher than control group at 8 h, 12 h, 24 h, 48 h, 3 d, 5 d, 7 d after admission, the
differences were statistically significant(P<0.05); The Scr levels of AKI group were significantly higher than non AKI group at 12 h, 24 h,
48 h, 3 d, 5 d, 7d after admission, the differences were statistically significant (P<0.05); The NGAL levels of AKI group at 2 h, 4 h, 8 h,
12 h, 24 h, 48 h, 3 d, 5 d, 7 d after admission, and non AKI group at 8 h, 12 h, 24 h, 48 h, 3 d, 5 d, 7 d after admission were significantly
higher than control group, the differences were statistically significant (P<0.05); The NGAL level in AKI group at 48h after admission to
the peak, then decreased slowly, and the NGAL level of AKI group was began significantly higher than non AKI group at 4h after
admission, the differences were statistically significant(P<0.05); The CysC levels of AKI group at 8 h after admission, and non AKI group
at 12 h after admission were began significantly higher than control group,the differences were statistically significant(P<0.05), the CysC
level of AKI group rose to the peak at 3 d after admission, and then began to slow down, and the CysC level in AKI group was began
significantly higher than that in non AKI group at 12 h after admission, the differences were statistically significant(P<0.05).Conclusion:The serum CysC and urinary NGAL levels in a short period after the paraquat poisoning will be unusually high, which has a positive
significance for the early diagnosis of AKI. |
