Abstract:
Objective To research expression changes of COX-2 gene in Barrett′s esophageal mucosa before and after argon plasma coagulation (APC)operation and to explore it′s clinical curative effect and possible mechanism .Methods 66 barrett′s e-sophageal diagnosed with gastroscope and pathology were randomly divided into normal esophageal group (the negative control group ,group A) ,the APC with acid suppression therapy group(group B) ,Acid antimicrobial drug treatment group(group C) .Ob-serve symptom relief condition ,barrett esophagus epithelium ablation under gastroscope before and after treatment ,esophageal mu-cosa tissue samples was detected by real-time fluorescent quantitative PCR technique .Expression of COX-2 gene in barrett′s esoph-ageal mucosa were compared among groups .Results Compared with group A ,both Group B and group C could effectively relieve symptoms (P<0 .05) .Symptom remission rate had no no statistically significant difference in Group B and group C .Barrett esopha-gus epithelium was not significantly narrowed under gastroscope follow-up Group A and group C ,while Barrett esophageal mucosal occurred ablation with pink mucous covered in Group B .The expression of Cox-2 mRNA in group B decreased ,which was similar to group A .The expression of Cox-2 mRNA in group C also decrease ,but there was no significant differences before and after treat-ment .Conclusion APC with acid suppression therapy could effectively relieve symptoms ,melting Barrett esophagus epithelium ,and is of a safe and effective treatment on Barrett′s esophagus .
