In large-scale hospitals practicing traditional Chinese medicine, there is accumulating experience related to the promotion of fast recovery in the perioperative period.AIM To evaluate the efficacy and safety of Yikou-Sizi powder hot compress on Shenque acupuncture point combined with rapid rehabilitation technique.METHODS This prospective, multicenter, randomized, controlled study included two groups: Treatment group and control group. The patients in the treatment group and control group received Yikou-Sizi powder hot compress on Shenque acupuncture point combined with rapid rehabilitation technique and routine treatment, respectively. Clinical observation regarding postoperative recovery of gastrointestinal function was performed, including the times to first passage of flatus, first defecation, and first normal bowel sounds. The comparison between groups was conducted through descriptive analysis, χ~2, t, F, and rank-sum tests.RESULTS There was a statistically significant difference in the time to postoperative first defecation between the treatment and control group(87.16 ± 32.09 vs 109.79 ±40.25 h, respectively;P < 0.05). Similarly, the time to initial recovery of bowel sounds in the treatment group was significantly shorter than that in the control group(61.17 ± 26.75 vs 79.19 ± 33.35 h, respectively;P < 0.05). However, there was no statistically significant difference in the time to initial exhaust between the treatment and control groups(51.54 ± 23.66 vs 62.24 ± 25.95 h, respectively;P >0.05). The hospitalization expenses for the two groups of patients were 62283.45 ±12413.90 and 62059.42 ± 11350.51 yuan, respectively. Although the cost of hospitalization was decreased in the control group, the difference was not statistically significant(P > 0.05). This clinical trial was safe without reports of any adverse reaction or event.CONCLUSION The rapid rehabilitation technique with integrated traditional Chinese and Western medicine promotes the recovery of postoperative gastrointestinal function and is significantly better than standard approach for patients after colorectal surgery.展开更多

Antroduodenojejunal manometry was used to monitor gastrointestinal motility in these subjects. After the subjects had fasted for at least 12 h, XBP(n = 30) or placebo(n = 10) was orally administrated and gastrointestinal motility was recorded for 4 h. Plasma motilin and ghrelin were measured by enzyme-linked immunosorbent assay.RESULTS Oral administration of XBP significantly increased the amplitude of duodenal contractions [19.5(13.0-26.7) vs 16.9(12.3-23.9), P < 0.05], jejunal contractions [18.3(15.3-25.0) vs 15.4(11.7-23.9), P < 0.01], and the motility index of duodenal contractions [522.0(146.0-139.0) vs 281.0(76.5-1006.0), P < 0.01] in phase Ⅱ of the migratory motor complex(MMC), which subsequently initiated the MMC cycle [74.0(30.0-118.0) vs 116.5(24.0-219.0), P < 0.05], shortened the duration of phase I of the MMC [42.0(0.0-90.0) vs 111.5(42.0-171.0), P < 0.01], and lengthened the duration of phase Ⅱ of the MMC [120(21-240) vs 58(16-170), P < 0.01] compared to the duration before XBP administration. There were significant differences in the amplitude of jejunal contractions [19.8(14.0-30.0) vs 18.0(13.0-28.5), P < 0.05], the motility index of duodenal contractions [236.0(115.0-306.0) vs 195.0(109.0-310.0), P < 0.05], and jejunal contractions [214.0(95.0-403.0) vs 178.0(55.0-304.0), P < 0.01] in phase Ⅲ of the MMC. Oral administration of XBP greatly increased plasma motilin(57.69 ± 9.03 vs 49.38 ± 8.63, P < 0.01) and ghrelin(279.20 ± 104.31 vs 238.73 ± 115.59, P < 0.01) concentrations compared to concentrations after oral administration of the placebo.CONCLUSION XBP can stimulate duodenal and jejunal motility and increase the concentrations of plasma motilin and ghrelin. The clinical applicability of XBP in treating GDIM deserves investigation.展开更多
