ABSTRACT

Objective To explore the efficacy of tepronone and folic acid in the treatment of chronic atrophic gastritis (CAG) evaluated by the marking targeting biopsy (MTB).Methods A total of 224 H.pylori negative CAG patients were selected and divided into group A (n 96,tepronone 50 mg/time,folic acid 10 mg/time,three times/day),group B (n=23,tepronone 50 mg/time,three times/day),group C (n=74,unspecific treatment) and group D (n=31,no treatment).The treatment course lasted for one year.The clinical symptoms improvement of each group was observed before and after treatment.The pathological improvement of gastric mucosa by MTB was inspected before and after treatment.The chi square test was performed for the comparison between groups.Results The total efficacy rates of group A,B,C and D were 43.8％ (42/96),39.1％ (9/23),33.8％(25/74) and 32.3％ (10/31) respectively,there was no significant difference between groups (x2 =2.328,P =0.507).For the significant efficacy rate of gastric mucosa pathological improvement,group A was compared with group D,group A was compared with group C and group B was comparedwith group D,the differences were significant (x2 =14.520,14.628 and 8.995,all P＜0.01).In the total efficacy rate of gastric mucosa pathological improvement,group A (49.8％,131/263) was compared with group D (24.2％,16/66),group A was compared with group C (35.9％,66/184)and group B (44.7％,21/47) was compared with group D,the differences were significant (x2 =13.953,8.535 and 5.207,all P＜0.05).Conclusion Teprenone alone or teprenone and folic acid combination can obviously improve pathological changes of CAG patients.
