摘  要:目的 探讨外周血 Th17细胞水平与儿童幽门螺杆菌(Helicobacterpylori,H.pylori)感染相关慢性胃炎的关系。方法 应用胃内镜检查诊断慢性胃炎,组织病理学检查对炎性反应的程度和活动度并进行分级;13C尿素呼气试验和胃黏膜尿素酶试验均阳性则视为H.pylori感染;应用流式细胞仪检测外周血 Th17细胞占总T淋巴细胞的比值。结果 慢性胃炎伴H.pylori感染患儿(HP组,33例)、慢性胃炎非 H.pylori感染患儿(非HP组,24例)和健康儿童(健康对照组,15例)的外周血 Th17细胞数分别为(1.55 ±0.30)% 、(1.06 ±0.33)% 和(1.04±0.35)% ,HP组显著增高于非HP组和健康对照组(P均 〈0.05),非 HP组与健康对照组间差异无统计学意义(P 〉0.05)。HP组不同炎症程度患儿Th17细胞数分别为(1.64 ±0.21)%(无炎症,10例)、(1.61±0.23)%(轻度炎症,8例)、(1.25 ±0.29)%(中度炎症,9例)、(1.75 ±0.20)%(重度炎症,6例),中度炎症组Th17细胞数最低,与其他组比较差异有统计学意义(P均 〈0.05),而其余3组间比较差异无统计学意义(P 〉0.05)。HP组不同炎症活动度患者 Th17细胞数分别为(1.23 ±0.25)%(无炎症,15例)、(1.53±0.15)%(轻度炎症,6例)、(1.55±0.32)%(中度炎症,6例)、(1.71±0.35)%(重度炎症,6例),4组间比较差异无统计学意义(P 〉0.05)。结论 Th17细胞在儿童 H.pylori感染慢性胃炎的过程中可能既有抗H.pylori感染的作用,又起到对患儿胃肠道的免疫病理损害作用。这可能成为临床治疗 H.pylori感染的新靶点。Objective To explore the relationship between peripheral Th17 cell number and chronic gastritis in Helicobacter pylori ( H. pylori) -infected children. Methods Children were diagnosed as chronic gastritis by endos- copy. The degree and activity of inflammation were graded by histopathology examinations. The patients with both 13C u- rea breath test and urease test positive were diagnosed as H. pylori infection. The peripheral Th17 cell number was measured by flow cytometry and expressed as a ratio to total T cell. Results The Th17 cell number in HP group (chro- nic gastritis with H. pylori infection, n = 33 ) , non-HP group ( chronic gastritis without H. pylori infection, n = 24 ) and normal controls ( n = 15 ) were ( 1.55 ±0.30) % , ( 1.06 ± 0.33 ) % , and ( 1.04± 0.35 ) % , respectively. HP group in- cluded a statistically higher Th17 cell number than the other groups (all P 〈 0.05 ) , while no obvious difference was found between non-HP group and controls ( P 〉 0.05 ). According to the degree of inflammation, the chronic gastritis with H. pylori infection was categorized into non-apparent (n = 10) ,mild (n =8) ,moderate (n =9) and severe (n = 6) subgroups. The Th17 cell number in each subgroup was ( 1.64 ± 0. 21 ) % (non-apparent) , ( 1.61± 0.23) % ( mild), ( 1.25 ± 0.29 ) % ( moderate ) and ( 1.75 ± 0.20 ) % ( severe), respectively. The moderate group had a lowest Th17 cell number among 4 groups ( P 〈 0.05 ). And significant differences did not exit in the other 3 groups ( P 〉 0.05 ). The HP group patients with different inflammatory activity had a Th17 cell number of ( 1.23 ±0.25 ) % in no- napparent (n=15) ,(1.53 ±0.15)% in mild (n=6) ,(1.55 ±0.32)% in moderate (n=6) and (1.71 ±0.35)% in severe (n = 6 ) subgroup, respectively. However, there were no significant differences among 4 subgroups (P 〉 0.05 ). Conclusions In the progress of chronic gastritis with H. p
