title: Therapeutic and recurrence-preventing effects of Qi-Replenishing and Blood-Activating Formula in rats with acetic acid-induced gastric ulcer.
abstract: OBJECTIVE
  To explore the therapeutic and recurrence-preventing effects of Qi-Replenishing and Blood-Activating Formula in rats with acetic acid-induced gastric ulcer.
  
  
  METHODS
  A total of 138 SD rats were selected to make rat models with gastric ulcer induced by acetic acid (24 rats with sham operation served as sham operation group), and were randomly divided into model group (n = 30), western medicine group (n = 30), traditional Chinese medicine (TCM) group (n = 24) and combination group (combined western medicine and TCM group, n = 30). Western medicine group was gavaged with omeprazole in the morning and with iso-volumetric distilled water in the afternoon; TCM group and TCM sham operation group were gavaged with iso-volumetric distilled water in the morning and with Qi-Replenishing and Blood-Activating Formula in the afternoon; combination group was gavaged with omeprazole in the morning and with Qi-Replenishing and Blood-Activating Formula in the afternoon; sham operation group and model group were gavaged with iso-volumetric distilled water both in the morning and afternoon. Ulcer indexes and degree of mucosal degree in rats at different time points after gavage were observed. Twenty-eight days after gavage, interleukin (IL)-1β was given to induce ulcer recurrence so as to observe the recurrent severity and rate of ulcer in each group.
  
  
  RESULTS
  Compared with model group and western medicine group, treatment in combination group could prominently reduce the ulcer index of rats with peptic ulcer, and increase the healing rate and inhibition rate of peptic ulcer. After IL-1β-induced ulcer recurrence, combination group was significantly superior to model group and western medicine group in ulcer recurrent rate [50% (3/6) vs. 100% (6/6)] and severity.
  
  
  CONCLUSIONS
  Basic acid-suppression therapy combined with Qi-Replenishing and Blood-Activating Formula can effectually improve the ulcer healing quality and reduce ulcer recurrence.
