【摘要】 目的 分析消化道息肉患者血清中性粒細(xì)胞明膠酶相關(guān)載脂蛋白(NGAL)的表達(dá)及其臨床意義。方法 對82例消化道息肉患者(息肉組)、30例消化道腫瘤患者(腫瘤組)和27例健康者(對照組)進(jìn)行血清NGAL和癌胚抗原(CEA)檢測。對檢測結(jié)果進(jìn)行對比分析。結(jié)果 腫瘤組、息肉組、對照組血清NAGL濃度分別為(142.90±36.16)、(121.03±41.01)、(103.14±21.91)?g/ml, 腫瘤組血清NAGL濃度高于息肉組及對照組, 差異有統(tǒng)計(jì)學(xué)意義(P<0.05);息肉組血清NAGL濃度高于對照組, 差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。腫瘤組、息肉組、對照組血清CEA濃度分別為(12.39±25.54)、(2.45±1.45)、(2.32±1.79)ng/ml, 腫瘤組血清CEA濃度明顯高于息肉組及對照組, 差異有統(tǒng)計(jì)學(xué)意義(P<0.05);息肉組及對照組血清CEA水平比較差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。結(jié)論 血清NGAL在消化道息肉、消化道腫瘤中表達(dá)逐漸升高, NGAL可能是篩查消化道癌前病變的潛在指標(biāo)。

【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(xì)胞明膠酶相關(guān)載脂蛋白(neutrophil gelatinase-associated lipocalin, NGAL)是Lipocalin家族的新成員, 在多種惡性腫瘤中異常表達(dá), 并與腫瘤浸潤、轉(zhuǎn)移、預(yù)后密切相關(guān)。目前關(guān)于NGAL與消化道息肉的相關(guān)性研究報道少見。本研究旨在探討血清NGAL在消化道息肉患者中的表達(dá)及其臨床意義。現(xiàn)報告如下。
1 資料與方法
1. 1 一般資料 收集2017年1~6月本院消化內(nèi)科收治的82例消化道息肉患者(息肉組)、30例消化道腫瘤患者(腫瘤組)為研究對象, 均經(jīng)內(nèi)鏡檢查+病理確診。息肉組中男44例, 女38例;年齡37~80歲;息肉類型:食管息肉2例, 胃息肉23例, 食管息肉合并胃息肉1例, 結(jié)直腸息肉47例, 胃息肉合并結(jié)腸息肉8例, 十二指腸息肉合并結(jié)腸息肉1例。腫瘤組中男16例, 女14例;年齡45~72歲;腫瘤類型:食管癌2例, 胃癌10例, 結(jié)直腸癌18例。所有患者均排除腎臟疾病、感染、嚴(yán)重心肺功能不全、腫瘤等疾病。選擇同期本院體檢健康志愿者27例為對照組, 其中男14例, 女13例;年齡30~71歲。三組性別、年齡等一般資料比較差異無統(tǒng)計(jì)學(xué)意義(P>0.05), 具有可比性。本研究經(jīng)興化市人民醫(yī)院倫理委員會批準(zhǔn), 所有受試者均知情同意。endprint
