Clinical values of miR-146a,miR-181a and MIF in diagnosis of Helicobacter pylori-associated gastric mucosal inflammation
OBJECTIVE To explore the expressions of microRNA(miR)-146a,miR-181a and macrophage migration inhibitory factor(MIF)in the patients with Helicobacter pylori-associated gastric mucosal inflammation and ana-lyze the clinical significance.METHODS Totally 208 patients with chronic gastritis who were treated in the Affilia-ted Hospital of Jiangnan University from May 2020 to Jan 2023 were assigned as the study group and were divided into the Hp-positive group with 142 cases and the Hp-negative group with 66 cases according to the status of H.pylori infection.Meanwhile,210 healthy people who received physical examination were chosen as the control group.Peripheral blood specimens were collected to detect the relative expression levels of miR-146a,miR-181a and MIF mRNA.The values of miR-146a,miR-181a and MIF in diagnosis of H.pylori-associated inflammation were analyzed by means of receiver operating characteristic(ROC)curves.RESULTS The relative expression lev-els of miR-146a,miR-181a and MIF mRNA of the study group were higher than those of the control group(P<0.05);the expression levels of the above indexes of the Hp-positive group were higher than those of the Hp-nega-tive group(P<0.05);the relative expression levels of mRNA of the above indexes of the Hp-positive group were associated with stomach pain,acid reflux,heartburn,history of H.pylori,dietary habit and pathogenesis site(P<0.05).The ROC curve analysis showed that the clinical value of the joint detection of miR-146a,miR-181a and MIF was high in diagnosis of H.pylori-associated gastric mucosal inflammation,with the area under curve(AUC)0.908,the sensitivity 88.70%,the specificity 75.80%.CONCLUSION The patients with chronic gastritis and H.pylori-associated gastric mucosal inflammation show high expression levels of miR-146a,miR-181a and MIF,and the high expressions of the above indexes in the patients with H.pylori-associated gastric mucosal in-flammation are associated with multiple factors,and the joint detection of the three indexes has high value in diag-nosis of the H.pylori-associated gastric mucosal inflammation.
