中性粒细胞明胶酶相关脂质运载蛋白与β2-微球蛋白对糖尿病肾病早期预测的临床价值

摘要

目的：研究中性粒细胞明胶酶相关脂质运载蛋白（NGAL）与β2‐微球蛋白（β2‐MG）对糖尿病肾病（DN ）的预测价值。方法选择2015年1月至2016年5月在该院接受治疗的 DN 患者78例（观察组），选择同期该院体检健康志愿者50例（健康对照组），比较2组研究对象的 NGAL 、β2‐MG 、尿素氮（BUN）、肌酐（SCr）及肾小球滤过率（eGFR）水平，并进行阳性率和相关性分析。结果观察组患者 NGAL 与β2‐MG 分别为（473．21±127．09）ng／mL 、（2．76±0．45）mg ／L ，显著高于健康对照组的（61．36±14．230）ng ／mL 、（0．81±0．14）mg／L ；观察组 NGAL 与β2‐MG 阳性检出率分别为96．15％（75／78）、91．03％（71／78），均显著高于健康对照组的2．00％（1／50）、6．00％（3／50）；观察组 BUN 、SCr 也显著高于健康对照组，但 eGFR 水平显著低于健康对照组，差异均有统计学意义（P＜0．05）。 NGAL 、β2‐MG 与 BUN 、SCr 呈正相关（R ＝0．812，P＝0．000；R ＝0．728，P ＝0．001；R ＝0．748，P＝0．001；R ＝0．685，P＝0．021），与 eGFR 呈负相关（R ＝－0．415，P ＝0．000；R ＝－0．371，P ＝0．000）。结论 DN 患者 NGAL 与β2‐MG 显著升高，两者还与 BUN 等存在明显的相关性，具有临床价值。%Objective To explore the neutral grain cell gelatinase associated lipid lipocalin(NGAL ) and β2 microglobulin (β2‐MG) predictive value of diabetic nephropathy(DN) .Methods From January 2015 to April 2016 in the hospital for 78 cases of DN patients recorded as the observation group ,and then 50 cases of healthy volunteers were choosen as the control group at the same period .NGAL ,β2‐MG ,BUN ,SCr and GFR levels were compared in the two groups .And the positive rate and correlation were ana‐lyzed .Results The levels of NGAL and β2‐MG in the observation group were(473 .21 ± 127 .09)ng/mL ,(2 .76 ± 0 .45)mg/L , which were significantly higher than that in the control group(61 .36 ± 14 .230)ng/mL ,(0 .81 ± 0 .14)mg / ,respectively .The posi‐tive rate of NGAL and β2‐MG in the observation group were 96 .15% (75/78) ,91 .03% (71/78) ,which were significantly higher than that of the control group of 2% (1/50) ,6% (3/50) .While the BUN ,SCr in observation groups were significantly higher than that in the control group ,while the level of eGFR was significantly lower than that of the control group ,the differences were statis‐tically significant(both P< 0 .05) .NGAL ,β2‐MG and BUN ,SCr showed positive correlation(R = 0 .812 ,P= 0 .000 ;R = 0 .728 ,P=0 .001 ;R = 0 .748 ,P= 0 .001 ;R = 0 .685 ,P = 0 .021 ) ,and eGFR showed a negative correlation (R = - 0 .415 ,P = 0 .000 ;R=- 0 .371 ,P= 0 .000) .Conclusion The level of NGAL and β2‐MG in DN patients is significantly increased ,NGAL ,β2‐MG levels are significantly correlated with BUN .
