Typical GSW tracings in the fed state at different sessions.

<p>(A) GSW on baseline. (B) GSW at RD session. (C) GSW at RD+AEA session. (D) GSW at RD+EA session. (E) GSW at RD+sham AEA session. (F) GSW at RD+atropine session. (G) GSW at RD+atropine+AEA session.</p

Experimental protocol.

<p>(A) GSW recordings in the fasting state at baseline and during RD; (B) GSW recordings in the fed state before and during RD or RD plus EA/AEA/sham-AEA; (C) GSW recordings in the fed state before RD and during RD at presence of atropine.</p

Effects of EA and AEA on RD-induced abnormal GSW.

<p>The percentage of GSW decreased significantly after RD in Control and Sham AEA group (^#P<0.05 RD vs baseline). While the abnormal GSW induced by RD were repaired significantly after using EA or AEA with RD (**P<0.05 RD plus EA/AEA vs RD). The effect between EA and AEA on repairing the impaired GSW induced by RD was no significant difference (P = 0.32).</p

Effects of RD on GSW at different pressures in fasting state.

<p>The percentage of normal GSW was not changed significantly (P>0.05) after RD with different pressure.</p

Effects of RD on Dominant frequency (DF) and dominant power (DP) of GSW.

<p>(A) DF was not altered significantly (P>0.05) after treatment comparing with that of baseline in each session. (B) EA at ST-36 increased DP of GSW significantly (*P<0.05, vs. baseline).</p

Effects of atropine treatment on the DF and DP of GSW.

<p>* <i>P</i><0.05 vs. baseline.</p><p>Effects of atropine treatment on the DF and DP of GSW.</p

Atropine blocked the preventive effect of AEA on RD-induced impairment in GSW.

<p>There was no significant difference of the percentage of GSW among 3 sessions after RD, RD+atropine or RD+atropine+AEA respectively (P>0.05).</p

Effects of AEA on RD-induced gastric dysrhythmia.

<p>EA reduced the percentage of bradygastria (B%) significantly during RD (#P<0.05, vs. RD). The percentage of tachygastrias (T%) decreased to 0% after using EA and AEA respectively during RD (^＊P<0.05, vs. RD). The percentage of arrhythmia (A%) decreased significantly as well after using EA and AEA respectively during RD (^※P<0.05, vs. RD).</p

Ameliorating effect of AEA on gastric hypersensitivity.

<p>AEA1, but not AEA2, reduced gastric hypersensitivity in FD rats. AEA1 decreased EMG responses to GD at 40, 60 and 80mmHg(AEA1 vs. Baseline, *p<0.01). (B) Sham-EA had no effect on gastric hypersensitivity in FD rats. (C) AEA1 could reduce the behavior responses in FD rats (*p<0.01, ^#p = 0.018). (D) AEA1 had no effect on gastric sensitivity in control rats.</p

AEA1 did not alter gastric emptying.

<p>There was no significant difference in gastric emptying among control group, FD+ AEA1 group and FD+sham-EA group.</p
