ABSTRACT

Objective To study the expression of hTERT in human gastric carcinoma and its precancerous lesions and to explore the relationship between hTERT expression and Helicobacter pylori (Hp) infection. Methods hTERT expression was detected by immunohistochemical method. Hp was detected by rapid urease test and Warthin-Starry silver staining. Results The expression level of hTERT in human gastric carcinoma (78.95%) was significantly higher than that in gastric dysplasia (64.29%), in intestinal metaplasia (46.67%), and in atrophic gastritis (25.00%, P
