摘　　要：目的探讨嗜酸性粒细胞(EOS)在腺样体肥大患儿组织和外周血中的分布水平及与变应因素的相关性。方法选择2017年10月—2018年7月于天津市第一中心医院耳鼻咽喉头颈外科行腺样体切除手术的患儿为研究对象。将112例患儿分为单纯腺样体肥大(AH)组62例,腺样体肥大伴变态反应性鼻炎(AH+AR)组50例。高倍镜下观察苏木精-伊红(HE)染色的组织切片中EOS数量,抽取外周血检验EOS百分比,对所有患儿进行血清特异性IgE检测及视觉模拟量表(VAS)评分,分析组织和外周血中EOS水平差异。绘制受试者工作特征(ROC)曲线,评价组织和外周血EOS水平对AH+AR的诊断价值。结果在腺样体肥大患儿中,AH+AR组EOS明显高于AH组(P<0.05),不同过敏原等级EOS水平差异无统计学意义(P>0.05)。在外周血中,伴重度变态反应性鼻炎组EOS水平明显高于轻度变态反应性鼻炎组(P<0.05),重度与中度、中度与轻度组间差异无统计学意义(P>0.05);在组织中,变态反应性鼻炎症状愈严重,EOS水平愈高(均P<0.05)。根据ROC曲线,分别计算曲线下面积(AUC):外周血(AUC=0.791,95%CI:0.705~0.878,P<0.001),截断点(cut-off值)为2.6%,此时敏感度为70.0%,特异度为74.2%;组织(AUC=0.843,95%CI:0.765~0.920,P<0.001),cut-off值为3/10个视野,此时敏感度为76.0%,特异度为80.6%。结论血清特异性IgE检测阳性的腺样体肥大患儿中腺样体组织和外周血EOS的水平增高,提示AH患儿的病因中有变应因素存在。组织中EOS水平较外周血对于变应因素的鉴别更具诊断意义。Objective To investigate the levels of eosinophils(EOS)in peripheral blood and tissues of children with adenoid hypertrophy,and its correlation with allergic factors.Methods A total of 112 children underwent adenoidectomy in the department of otorhinolaryngology,head and neck surgery of Tianjin First Center Hospital from October 2017 to July 2018 were selected as the study objects.These children were divided into two study groups:adenoid hypertrophy only(AH,n=62)group and adenoid hypertrophy with allergic rhinitis(AH+AR,n=50)group.The number of EOS in tissue sections stained with hematoxylin-eosin(HE)was observed under high power microscope.The percentage of EOS in peripheral blood was detected.In addition,the serum specific IgE detection and visual analogue scales(VAS)were performed in all children,and the differences of the levels of EOS in tissues and peripheral blood were analyzed.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of the EOS levels in tissues and peripheral blood for allergic factors in children with AH+AR.Results The EOS level was significantly higher in AH+AR group than that in AH group(P<0.05).There were no significant differences in EOS levels between different levels of allergen(P>0.05).The EOS level in peripheral blood was significantly higher in patients with severe allergic rhinitis than that of patients with mild allergic rhinitis(P<0.05).There were no significant differences in the EOS levels between severe and moderate rhinitis,moderate and mild rhinitis(P>0.05).In tissues,the more severe the symptoms of allergic rhinitis are,the higher the level of EOS is(P<0.05).According to the ROC curve,the area under the curve(AUC):peripheral blood was 0.791(95%CI:0.705-0.878,P<0.001),the cut-off value was 2.60%,and the sensitivity was 70.0%,the specificity was 74.2%;and in tissue AUC was 0.843(95%CI:0.765-0.920,P<0.001),the cut-off value was 3/10 sections,and the sensitivity was 76.0%and the specificity was 80.6%.Conclusion The EOS levels in adenoid tiss
