[Effects of dachengqi decoction on gut hormones and intestinal movement after cholecystectomy]

In order to elucidate the mechanism of postoperative intestinal dysfunction and the effects of Dachengqui Decoction (DCQD) on it, somatostatin (SS), gastrin (GAS), vasoactive intestinal polypeptide (VIP), substance P (SP), motilin (MOT) and atrial natriuretic peptide (ANP) were determined, frequency and spectrum of peristaltic sound were simultaneously analyzed in 31 subjects undergoing cholecystectomy, the value of pre-, post-operation and post-medication were compared. Plasma SS and MOT decreased postoperatively (P < 0.05), DCQD elevated SS and MOT to higher level than preoperation, VIP, SP increased for half fold (P < 0.05). Gurgling sound diminished after operation, whereas DCQD normalized it. Peak frequency (Fmax) of gurgling ranging from 234.4 to 468.2 Hz preoperatively, mean frequency (FA) was 341.8 +/- 30.9 Hz postoperatively. FA reduced to 322.3 +/- 79.4, DCQD elevated it to 374.2 +/- 57.1 Hz. The result suggested that intestinal motility was disturbed after cholecystectomy, bowel was in dystonic status, accompanying with decreased plasma MOT, DCQD promoted intestinal peristalsis and enhanced it's tonus. The influence of gut peptides might be one of the important pathway that DCQD works.
