[摘要] 目的 研究幽门螺杆菌(Helicobacter pylori)感染与肠上皮化生不同亚型中C-myc蛋白表达的关系。 方法 应用14碳-呼气试验检测Hp；AB-PAS和HID-AB黏液染色法进行肠上皮化生亚型分型；应用免疫组织化学染色Elivision法检测C-myc蛋白的表达。 结果 肠上皮化生各亚型Hp感染率均高于非萎缩性胃炎组，各亚型之间Hp感染率无明显差异；不完全性结肠化生C-myc蛋白表达率高于其他亚型和非萎缩性胃炎(P < 0.05)；不完全性结肠性化生中Hp阳性患者C-myc蛋白表达率明显高于Hp阴性患者(P < 0.01)。 结论 不完全性结肠化生中C-myc蛋白表达升高，其表达可能与Hp感染有关，Hp感染可能通过C-myc基因参与胃癌发生，同时提示不完全性结肠化生与胃癌关系密切。

[Abstract] Objective To study the association among Helicobacter pylori (Hp) infection and the expression of C-myc protein in different subtypes of intestinal metaplasia. Methods The Carbon-14-Urea Breath Test was used to determine Hp； AB-PAS and HID-AB mucinous staining was used to distinguish intestinal metaplasia subtypes； The immunohistochemical Elivision method was used to determine the expression of C-myc protein. Results The infection rates of Hp in intestinal metaplasia was higher than non-atrophic gastritis； No significant difference between subtypes of intestinal metaplasia in the infection rates of Hp. The expression of C-myc protein in incomplete colonic type of intestinal metaplasial was higher than other subtypes and non-atrophic gastritis， the expression of C-myc protein with Hp positive was higher than those with Hp negative ......
