Abstract:
Objective To evaluate the significance of electronic gastroscopy examination combined with miR-21 in the diagnosis of gastric carcinoma.Methods 96 gastroscopy cases in Guangzhou General Hospital of Guangzhou Military Command were adopted from June,2011 to December,2012.The patients received gastric endoscopy examination,and the diseased tissue samples were taken out at the same time.To calculate the diagnosis rate and missed rate with gastroscopy,by comparing the gastroscopy diagnosis with the pathology diagnosis.To evaluate the expression level of miR-21 of the tissue by applying quantitative real time PCR.Results The diagnosis rates of gastric cancer,gastric ulcer,chronic superficial gastritis,gastroesophageal reflux gastritis,chronic atrophic gastritis under gastroscopy were 28.12 ％ (27/96),30.21％ (29/96),18.75 ％ (18/96),10.42 ％ (10/96),12.50 ％ (12/96).The diagnosis rate of gastric cancer was 100.00 ％ and the missed diagnosis rate was 6.90 ％ (2/29),the relative transcript level of miR-21 in the gastric cancer group was 54.41±6.66,which was obviously higher than the gastric ulcer group and the other groups (P ＜ 0.01).Conclusions Electronic gastroscopy is a clinically practical examination method in screening gastric cancer cases,evaluating the expression level of miR-21 in the diseased tissue under gastroscopy can enhance the accuracy of screening gastric cancer.Combining the two methods is useful in the diagnosis of gastric cancer.
