ABSTRACT
Objective To investigate the correlation between Helicobacter pylori (HP) infection-associated gastritis and the ap-optotic genes in gastric mucosa .Methods Forty-five patients with chronic gastritis were registrated in our study from November 2013 to December 2014 .HP infection status in the patients was detected by using urease test and 13C-urea breath test .The degree of gastritis in the gastric mucosa with HP infection was confirmed via histopathology .qRT-PCR was used to measure the mRNA ex-pressions of Bax ,Bak and Bcl-2 in the gastric mucosa with HP infection and matched normal gastric mucosa .Person analysis was used to assess the correlation between the HP infection-associated gastritis and the mRNA expressions of Bax ,Bak and Bcl-2 in the gastric mucosa .Results Forty-five patients with HP infection in antrum and 45 patients (100% ) with chronic antrum gastritis were identified ,including 28 patients (62 .2% ) with light gastritis ,16 patients (35 .6% ) with moderate gastritis ,1 patient (2 .0% ) with severe gastritis .9 patients (20 .0% )with metaplasia ,5 patients(11 .1% ) with low grade intraepithelial neoplasms .The urease tests were negative in the gastric body of 45 patients ,6 patients (13 .3% )were mild chronic gastritis in the body ;Patient with meta-plasia and intrapithelial gastritis was not found .The Bax expression in the HP-infected gastric mucosa was markedly increased when compared with the normal gastric mucosa (P0 .05) .Conclusion HP infec-tion-associated gastritis positively correlated with the expressions of apoptotic genes in gastric mucosa ,suggesting that HP infection might result in increasing the Bax expression and further enhancing the cell apoptosis .
