【摘要】 目的 分析消化道息肉患者血清中性粒细胞明胶酶相关载脂蛋白(NGAL)的表达及其临床意义。方法 对82例消化道息肉患者(息肉组)、30例消化道肿瘤患者(肿瘤组)和27例健康者(对照组)进行血清NGAL和癌胚抗原(CEA)检测。对检测结果进行对比分析。结果 肿瘤组、息肉组、对照组血清NAGL浓度分别为(142.90±36.16)、(121.03±41.01)、(103.14±21.91)?g/ml, 肿瘤组血清NAGL浓度高于息肉组及对照组, 差异有统计学意义(P<0.05);息肉组血清NAGL浓度高于对照组, 差异有统计学意义(P<0.05)。肿瘤组、息肉组、对照组血清CEA浓度分别为(12.39±25.54)、(2.45±1.45)、(2.32±1.79)ng/ml, 肿瘤组血清CEA浓度明显高于息肉组及对照组, 差异有统计学意义(P<0.05);息肉组及对照组血清CEA水平比较差异无统计学意义(P>0.05)。结论 血清NGAL在消化道息肉、消化道肿瘤中表达逐渐升高, NGAL可能是筛查消化道癌前病变的潜在指标。

【Abstract】 Objective To analyze the expression of serum neutrophil gelatinase-associated lipocalin (NGAL) in patients with gastrointestinal polyps and its clinical significance. Methods Serum NGAL and carcinoembryonic antigen (CEA) were detected in 82 patients with digestive tract polyp (polyp group), 30 patients with digestive tract tumor (tumor group) and 27 healthy subjects (control group). Comparative analysis was made on the detection results. Results Tumor group, poly group and control group had content of serum NAGL respectively as (142.90±36.16), (121.03±41.01) and (103.14±21.91) ?g/ml. Tumor group had higher content of serum NAGL than polyp group and control group, and the difference was statistically significant (P<0.05). Polyp group had higher content of serum NAGL than control group, and the difference was statistically significant (P<0.05). Tumor group, polyp group had control group had content of serum CEA respectively as (12.39±25.54), (2.45±1.45) and (2.32±1.79) ng/ml. Tumor group had obviously higher content of serum CEA than polyp group and control group, and the difference was statistically significant (P<0.05). Polyp group had no statistically significant difference in serum CES levels comparing with the control group (P>0.05). Conclusion The expression of serum NGAL in digestive tract polyp and digestive tract tumor gradually increased, and NGAL might be a potential index for screening precancerous lesions of digestive tract.

中性粒細胞明胶酶相关载脂蛋白(neutrophil gelatinase-associated lipocalin, NGAL)是Lipocalin家族的新成员, 在多种恶性肿瘤中异常表达, 并与肿瘤浸润、转移、预后密切相关。目前关于NGAL与消化道息肉的相关性研究报道少见。本研究旨在探讨血清NGAL在消化道息肉患者中的表达及其临床意义。现报告如下。
