Abstract

OBJECTIVE

To observe the relatively specific effect of electroacupuncture (EA) of "Xiajuxu" (ST 39, the lower hesea paint of the small intestine), etc. on the level of serum TNF-alpha, lnterleukin-1 P (IL-1 P) and high mobility group protein B 1 (HMGB 1) contents, and duodenum a7 nicotinic acetyicholine receptor (nAchR) expression in duodenal ulcer rats, so as to explore its mechanisms underlying improving duodenal ulcer.

METHODS

Sixty SD rats were randomly divided into 6 groups: normal control, model, Xiajuxu (ST 39), Zusanli (ST 36), Shangjuxu (ST 37) and Yanglingquan (GB 34). The duodenal ulcer model was established by subcutaneous injection of 10% Cysteamine Hydrochloride (300 mg/kg), following by giving the rats with access to water containing Cysteamine. EA (10 Hz/50 Hz, 1- 3 mA) was applied to bilateral ST 39, ST 36, ST 37 and GB 34 for 30 min, once daily for 10 days. The ulcer scores (0-5 points) of the duodenal mucosa were assessed according to modified Moraes' methods. Serum TNF-alpha, IL-1 beta and HMGB 1 levels were assayed by ELISA and the expression of neuronal a7 nAchR in the duodenal tissue was detected by Western blot.

RESULTS

After modeling, the ulcer score, serum TNF-alpha, IL-i p and HMGB 1 contents were significantly increased (P<0.01) and the expression level of a7 nAchR in the duodenal tissue was significantly down- regulated in comparison with the normal control group (P<0.01). Following EA intervention, the serum TNF-alpha and HMGB 1 con- tents in the Xiajuxu(ST 39), Zusanli (ST 36), Shangjuxu (ST 37) and Yanglingquan (GB 34) groups, and the ulcer scores and IL-1 beta content of the Xiajuxu(ST 39), Zusanli (ST 36) and Shangjuxu (ST 37) groups were considerably reduced, and the expression of alpha7 nAchR in both Xiajuxu (ST 39) and Zusanli (ST 36) groups was evidently increased (P<0.05, P<0.0.1). No significant changes were found in the ulcer score, serum IL-1 beta content, and a7 nAchR expression in the Yanglingquan (GB 34) group and a 7 nAchR expression in the Shangjuxu (ST 37) group in comparison with the model group (P>0.05).

CONCLUSION

EA stimulation of ST 36, ST 37 and ST 39 can reduce ulcer injury in duodenal ulcer model rats, which may be associated with their effects in down-regulating serum TNF-alpha, IL-1 beta and HMGB 1 contents and up-regulating alpha7 nAchR expression of the duodenal tissue, possibly by suppressing immune and inflammatory reactions and regulating nicotinic activity.
