RÉSUMÉ

Objective:To explore the regulation effect and possible mechanism of transcutaneous electrical acustimulation (TEA) on the improvement of gastrointestinal motility and inflammation in patients with acute pancreatitis (AP).Methods:A randomized, single-blinded, sham-controlled study was performed. A total of 62 AP patients were randomly divided into the TEA group ( n=31) and sham-TEA group ( n=31), on the basis of regular treatment, who received TEA treatment at Neiguan (PC6) and Zusanli (ST36) or sham-TEA treatment at corresponding pseudo stimulation acupoints for 2 days. Abdominal distension score, time to first defecation, gastric slow wave, heart rate variability (low frequency and high frequency, reflecting sympathetic and vagal activity, respectively), serum level of tumor tecrosis factor (TNF)-α, plasma levels of motilin, ghrelin and vasoactive intestinal peptide(VIP) tested by enzyme linked immunosorbent assay were compared before and after the treatment. Wilcoxon rank test, Mann-Whitney U test, t-test and two factor repeated measurement analysis of variance were used for statistical analysis. Results:After the treatment, abdominal distension score of TEA group was lower than that of sham-TEA group(1 (0 to 2) vs.5(3 to 6)) and time to first defecation was earlier than that of sham-TEA group((55.00±24.27) h vs.(67.95±23.84) h), the percentage of normal gastric slow wave was higher than that of sham-TEA group((57.42±11.16)% vs. (40.92±8.52)%), and the differences were statistically significant ( Z=-4.95、 t=-2.12、 F=61.53, all P<0.05). After the treatment, the serum level of TNF-α of TEA group was significantly lower than that of sham-TEA group((4.27±1.28) ng/L vs.(6.19±2.03) ng/L), and the difference was statistically significant ( F=28.65, P<0.05). The ratio of post/pre-treatment of low frequency heart rate variability of the TEA group was significantly lower than that of sham-TEA group, however, the result of high frequency was opposite (0.87±0.18 vs.1.14±0.16, 1.19±0.18 vs.0.96±0.13), and the differences were statistically significant ( t=-6.22 and 5.74, both P<0.05). After the treatment, the plasma level of ghrelin of TEA group was higher than that of sham-TEA group ((2.02±0.62) μg/L vs. (0.93±0.49) μg/L), the VIP level was lower than of sham-TEA group ((30.58±12.20) μg/L vs.(44.35±29.52) μg/L), and the differences were statistically significant ( F=59.22 and 5.50, both P<0.05). However, there was no significant difference in motilin levels between two groups ((24.57±9.58) ng/L vs. (22.75±9.58) ng/L, P>0.05). Conclusion:TEA treatment can improve gastrointestinal motility and inhibit the inflammation in early AP, which may be related with the regulation of autonomic function, gastrointestinal hormone ghrelin and VIP.

RÉSUMÉ

In recent years, as a new treatment method developed on the basis of traditional acupuncture, electrical stimulation, including electroacupuncture and transcutaneous electrical acustimulation, has shown great potential in the treatment of various gastrointestinal diseases. Because of the characteristics of family therapy, it can greatly reduce the cost of treatment and has a comparative advantage over drug therapy, however, it has not been widely used in clinical practice. This article reviewed the advantages and disadvantages of electrical stimulation, stimulation parameters, mechanism, and research progress of the treatment.
