    Abstract:
    OBJECTIVE: To explore relevant material basis of moxibustion for recovering gastric mucosal lesion. METHODL Forty-five SD rats were randomly divided into a normal goup, a model group, an acupoint group and a control group, 15 rats in the model group and 10 rats in the rest three groups. Except the normal group, binding and cold stress method were used to establish gastric mucosa injury model. The suspended moxibustion was applied in the acupoint group and control group at acupoints of the stomach meridian ("Liangmen" (ST 21) and "Zusanli" (ST36) and control acupoints (Laterally 1cm next to the "Liangmen" (ST 21) and Zusanli" (ST36), once a day, consectutively for 12 days. After 12 days, morphology of gastric mucosal was observed under optical microscope; protein fingerprints of gastric mucosa cell in rats were detected by protein fingerprint technology, weak cation chip and weak anion chip. Also mass to charge ratio of differential proteins in groups were compared and analyzed. RESULTS: Compared with the model group, index of gastric mucosal lesion in the acupoint group was reduced and its morphology was obviously improved (P<0.05). Campared with control group, index and morphology of gastric mucosal lesion were significantly improved in the acupoint group (P<0.05). According to test of weak cation chip, there was four marker proteins that had expression differences, indicating moxibustion at acupoints of stomach meridian could inrease expression of three marker protein whose molecular weight was 1354Da, 5692Da and 8432Da (all P<0.05) while reduce expression of marker protein with molecular weight of 3287Da (_<0.05). According to test of weak anion chip, moxibustion at acupoints of stomach meridian could increase expression of three marker proteins whose molecular weight was 2412 Da, 3026Da and 6475 Da (allP<0.05). CONCLUSION: Moxibustion at acupoints of the stomach meridian could regulate differential expression of gastric mucosa cell-related marker protein in rats with acute gastric ulcer and recover gastric mucosal lesion, it's effect is better than that of the points of laterally 1 cm next to acupoint.
