To investigate the relationship between apoptosis-related proteins in gastric mucosa, p53 and Bax, and Helicobacter pylori (H. pylori) infection in children.
p53 and Bax expression in gastric mucosa were measured using immunohistochemical technique in 33 children with gastric mucosal lesions. Presence/absence of H. pylori infection was detected by the rapid urease and pathological tests.
Fifteen children (88%) showed positive expression of p53 in 17 children who were confirmed with H. pylori infection, compared with 9 (56%) in 16 H. pylori negative children. Thirteen children (76%) showed positive expression of Bax in the 17 children with H. pylori infection, compared with 6 (38%) in the 16 H. pylori negative children. The expression levels of p53 and Bax in the H. pylori positive group were significantly higher than those in the H. pylori negative group (p<0.05).
H. pylori infection is associated with the over-expression of p53 and Bax proteins in gastric mucosa in children.
探讨儿童胃黏膜中凋亡相关蛋白p53和Bax与幽门螺杆菌（H. pylori）感染之间的关系。
采用免疫组化技术检测33例胃黏膜病变患儿胃黏膜中p53和Bax的表达。通过快速尿素酶试验和病理检查检测是否存在H. pylori感染。
17例确诊为H. pylori感染的患儿中，15例（88%）p53呈阳性表达，而16例H. pylori阴性患儿中9例（56%）呈阳性表达。17例H. pylori感染患儿中，13例（76%）Bax呈阳性表达，而16例H. pylori阴性患儿中6例（38%）呈阳性表达。H. pylori阳性组中p53和Bax的表达水平显著高于H. pylori阴性组（p<0.05）。
H. pylori感染与儿童胃黏膜中p53和Bax蛋白的过度表达有关。
