摘要
Objective Nephrolithiasis is one of the most common disorders of the urinary tract. The aim of this study was to examine a possible relationship between DNase Ⅰ/Ⅱ activity and E3 SUMO-protein ligase NSE2 in the sera of nephrolithiasis patients to evaluate the possibility of a new biomarker for evaluating kidney damage. Methods Sixty nephrolithiasis patients and 50 control patients were enrolled in a case-control study. Their blood urea, creatinine, protein levels and DNase Ⅰ/Ⅱ activity levels were measured by spectrometry. Serum NSMCE2 levels were measured by ELISA. Blood was collected from patients of the government health clinics in Kuantan-Pahang and fulfilled the inclusion criteria. Results The result indicated that mean levels of sera NSMCE2 have a significantly increase（P〈0.01） in patients compared to control group. Compared with control subjects, activities and specific activities of serum DNase Ⅰ and Ⅱ were significantly elevated in nephrolithiasis patients（P〈0.01）. Conclusion This study suggests that an increase in serum concentrations of DNase Ⅰ/Ⅱ and E3 SUMO-protein ligase NSE2 level can be used as indicators for the diagnosis of kidney injury in patients with nephrolithiasis.
