Objective To study the effect of gastrin, motilin of chronic atrophic gastritis model in rats by acupuncturing at back-shu points. Methods 60 SD rats were randomly divided into blank control group, model control group, omeprazole group, back-shu points group, with 15 rats in each group, and to establish the model of chronic atrophic gastritis by irregular diet that given rats odd and even days. The blank control group, model control group were fed with normal saline, 2ml/time, 1 time/day. The omeprazole group was given oral gavage(Omeprazole 0.44 mg/kg, Clarithromycin 6.92 mg/kg, Metronidazole 7.6 mg/kg), 1 time/day. Back-shu points group received acupuncture at “Geshu”“Ganshu”“Pishu”“Weishu”“Shenshu”, retaining 15 min, 1 time/day. After 30 days, the content of ELSIA was used to detect the serum gastrin, motilin. Results ①GAS of model control group(54.25±5.70)pg/ml was significantly decreased compared with blank control group(66.63± 5.99)pg/ml, the difference was statistically significant (P<0.05). Compared with the model control group, GAS content of omeprazole group(62.70±8.55)pg/ml and back-shu Points group(66.27±3.79)pg/ml were higher, showed significant differences(P<0.05). ②MOT of model control group(223.60±17.83)pg/ml was significantly increased compared with the blank control group(188.45 ± 8.90)pg/ml, the difference was statistically significant(P<0.05). MOT of omeprazole group(200.16 ± 4.38)pg/ml and back-shu Points group(190.11±10.04)pg/ml were lower than those in the model control group, there was statistically significant difference(P<0.05). Conclusion Acupuncturing at back-shu acupoints can increase the content of GAS, reduce content of MOT, regulate gastrointestinal hormone in rats of chronic atrophic gastritis model.
