The significance of Hp antigen combined with serum total sialic acid and gastric mucosal Survivin detection in the diagnosis of gastric adenocarcinoma / 国际检验医学杂志

ABSTRACT

Objective To explore the significance of Hp antigen combined with serum total sialic acid and gastric mucosal Survivin detection in the diagnosis of gastric adenocarcinoma.Methods Selected a hospital 90cases of patients with gastric adenocarcinoma (malignant group) and 90cases of the digestive system benign disease (benign disease group) and hospital check-up of 60cases of healthy people (healthy control group) as the research object.Comparing the three groups of patients with Hp antigen, serum total sialic acid positive detection rate and the positive rate of Survivin in the gastric mucosa, and to assess individual detection of Hp antigen, serum total sialic acid and the two combined diagnostic sensitivity and specificity of gastric adenocarcinomas.Results Hp antigen, serum total sialic acid positive test results showed that the malignant tumor group were significantly higher than that of benign disease group and healthy control group, benign disease group obviously higher than that of healthy control group, difference between three groups of participants were statistically significant (P<0.05) .The sensitivity of Hp antigen and serum total sialic acid combined in the diagnosis of digestive system was 80.1％, which was significantly higher than that of single test, but the specificity was reduced.Linear correlation analysis showed that there was a positive correlation between Hp antigen and serum total sialic acid and Survivin detection in gastric mucosa, and the correlation was high (r=0.94, P<0.05) .Conclusion The combined detection of Hp antigen and total serum sialic acid is positively correlated with the results of Survivin detection in gastric mucosa, and has a high correlation.It can replace Survivin detection in gastric mucosa as a sensitive index for the diagnosis of gastric adenocarcinoma.
