    • 摘要: 中性粒细胞明胶酶相关载脂蛋白(NGAL)早期的研究是围绕其作为急性肾损伤(AKI)新的早期诊断标志物展开,随后的研究发现它在慢性肾脏病、继发性肾脏病方面同样具有灵敏的诊断价值和预测作用,尤其在急慢性肾脏疾病的生物学预测价值和预后评估方面越发得以体现.因此本文重点围绕NGAL与肾脏损伤方面的研究展开综述.

    • 摘要: Objective To investigate the clinical significance of serum and urinary levels of neutrophil gelatinase-associated lipocalin (NGAL ) for evaluating changes of residual renal function after living donor kidney resection under different operation model in young versus elderly patients. Methods The clinical data of renal transplants were retrospectively analyzed by successfully using 66 living-related donors at the First Affiliated Hospital of Zhengzhou University from September 2016 to October 2017. According to the operation model and age ,renal donors were divided into 4 groups :group A (young/open) ,group B (young/laparoscopic) ,group C (aged/open) ,and group D (aged/laparoscopic).Blood and urinary NGAL and serum levels of creatinine ,cystatin C ,and other indices of renal function were assayed and collected before and at 1 ,3 ,7 days after operation. Results Both blood NGAL levels and urinary NGAL levels showed no statistically significant difference (all P>0.05) among four groups both before and after operation ,except that urinary NGAL was higher in group C (aged/open) than other groups ,at 1 day after operation ,(P = 0.03).The post-vs.pre-operation level dynamic changes of renal function were four or three times higher in urine or serum NGAL level than in serum creatinine or cystatin C level at 1 day after operation ,which showed an important role for predicting an early residual renal damage and relative treatment. Conclusions NGAL can be used as indices in evaluating changes of residual renal function after living donor kidney resection ,especially in the elderly receiving open kidney resection.%目的 探讨中性粒细胞明胶酶相关脂质运载蛋白(NGAL)在评价不同年龄、不同术式活体供肾切取术后残肾功能的临床意义.方法 回顾性分析2016年9月至2017年10月在郑州大学第一附属医院成功实行亲属活体肾移植的66例供者临床资料.根据术式、年龄将供者分为4组:青年开放组、青年腔镜组、中老年开放组、中老年腔镜组;记录供者术前及术后1、3和7d血、尿NGAL、血肌酐和胱抑素C等肾功能监测指标.结果 4组的术前血、尿NGAL差异无统计学意义(P>0.05);术后第1天老年开放组尿NGAL均高于其他3组(P0.05);术后第3天中老年开放组血NGAL高于中老年腔镜组(P<0.05).结论 NGAL可作为活体供肾切取术后残肾功能的评估指标,尤其在评估中老年及开放性供肾的残肾功能时更为敏感,有助于早期发现供者术后急性肾损伤.

    • 摘要: 目的 探讨尿液中尿微量清蛋白(mAlb)、中性粒细胞明胶酶相关脂质运载蛋白(NGAL)、血清胱抑素C(Cys-C)、同型半胱氨酸(HCY)对糖尿病早期肾损害的诊断价值.方法 选择126例糖尿病患者,按照尿白蛋白的常规检测结果:糖尿病无肾病40例(A组)、早期糖尿病肾病47例(B组)、糖尿病肾病39例(C组),选择同期健康体检者50例为对照组.检测患者尿mAlb、NGAL和血清Cys-C、HCY,探讨四个指标与糖尿病早期肾损伤的相关关系,以及联合检测对糖尿病早期肾损伤的诊断价值.结果 C组NGAL、mAlb、Cys-C、HCY水平分别为(191.3 ±36.27) ng/ml、(71.46 ±7.56) mg/L、(2.96±1.02)mg/L、(24.23±6.08) mol/L显著高于其他组,差异有统计学意义(P<0.05).随着肾损害的加重,四项指标的阳性检出率逐渐提高.NGAL、mAlb、Cys-C、HCY与糖尿病早期肾损伤的关联系数为3.91、3.85、3.34和3.16.联合检测对糖尿病早期肾损伤的敏感度和特异度分别是94.68%、95.94%,显著高于四项指标单独检测的值,差异有统计学意义(P<0.05).结论 NGAL、mAlb、Cys-C、HCY与糖尿病早期肾损伤存在正相关,联合检测对糖尿病早期肾损害具有较高的诊断价值.

    • 摘要: Objective To investigate the application of neutrophil gelatinase associated lipocalin(NGAL) in septic newborns. Methods We determined serum and urine NGAL concentrations in 93 infants(55 with sepsis, 38 with severe sepsis), for three consecutive days during the course of treatment for infection. Thirty-five neonates without infecting served as the control group. Results Septic patients, in particular, severe sepsis patients, had increased serum and urinary NGAL levels in the three subsequent days of observation. A strong correlation was found between the concentration of serum and urinary NGAL and inflammatory markers, such as C-reactive protein (CRP) and pro-calcitonin (PCT). Serum and urinary NGAL levels were also significantly associated with NTISS values. Conclusion We conclude that increased serum and urinary NGAL values are not solely a marker of AKI, and more accurately reflect the severity of infla mmatory status.%目的探讨新生儿败血症患者对血清、尿液中性粒细胞明胶酶相关脂质运载蛋白(NGAL)水平的影响。方法检测93例新生儿败血症患者(其中败血症55例、严重败血症38例)血清及尿液NGAL水平,在感染治疗期间连续监测3 d。35例无感染新生儿为对照组。同时检测C-反应蛋白(CRP)、血清降钙素原(PCT)等炎症标志物。结果在后续3 d观察中发现败血症特别是严重败血症患者血清和尿液中NGAL水平均升高。血清、尿液中NGAL水平升高的程度与CRP、PCT等炎症标志物有明显的相关性。与新生儿治疗干预评分系统(NTISS)评分也存在明显的相关。结论 NGAL不仅仅是急性肾损伤的指标,也能反映败血症的严重程度。

    • 摘要: 目的:检测原发性高血压(Essential hypertension,EH)患者血浆中性粒细胞明胶酶相关脂质运载蛋白(neutrophil gelatinase -associated lipocalin,NGAL)和血清胱抑素 C(CysC)的浓度并探讨其临床意义。方法选取92例 EH 患者为 EH 组,另选取88例健康体检者作为健康对照组。对所有入选对象分别检测血浆 NGAL 和血清 CysC 的浓度及各项生化指标,各组间进行比较。结果EH 组血浆 NGAL 浓度为(149.22±11.52)μg/L,血清 CysC 的浓度为(0.92±0.03)mmol/L;健康对照组血浆 NGAL 浓度为(101.4±7.71)μg/L,血清 CysC 的浓度为(0.71±0.02)mmol/L。EH 组血浆 NGAL 浓度和血清 CysC 浓度均明显高于对照组(F =27.491,P <0.01;F =24.646,P <0.01);且血浆 NGAL 浓度在 EH 1级、2级和3级间呈逐渐增高趋势。血浆NGAL 与血清 CysC 浓度呈正相关(r =0.48,P <0.01)。结论EH 患者血浆 NGAL 和血清 CysC 的水平明显升高,且与高血压的分级及由高血压引起的肾脏损伤程度密切相关,两者均可作为早期发现 EH 引起的肾功能损害的诊断指标。%Objective To explore the levels of neutrophil gelatinase -associated lipocalin(NGAL)and Ser-um cystatin C(CysC)in plasma in essential hypertension(EH)and to discuss their clinical significance.Methods 92 patients with essential hypertension were selected as EH group.At the same time,88 healthy subjects were selected as the healthy control group.The levels of plasma NGAL,serum CysC and some other biochemical markers were detected.The results were statistically processed.Results The level of Plasma NGAL in EH group was(149.22 ± 11.52)μg/L and the level of serum CysC in EH group was(0.92 ±0.03)mmol/L.The level of Plasma NGAL in the healthy control group was(101.4 ±7.71)μg/L and the level of serum CysC in the healthy control group was(0.71 ± 0.02)mmol/L.The levels of Plasma NGAL and serum CysC were significantly increased in EH group compared with those of the healthy control group(F =27.491,P <0.01;F =24.646,P <0.01).Plasma NGAL was positively corre-lated with the degree of EH and the level of serum CysC(r =0.48,P <0.01).Conclusion Plasma NGAL and serum CysC were significantly increased in EH patients,with a significant positive correlation to the degree of nephropathy damage.Both of them can become diagnostic measurements for early diagnosis of nephropathy damage induced by EH.
