OBJECTIVE: To explore different regulatory effects of electroacupuncture (EA) at the same acupoint on the heart and the stomach. METHODS: Eighty male SD @entity35 were randomly divided into eight groups equally, i.e., the Neiguan ( @entity16518 ) group, the Quchi (LI11) group, the Tianshu (ST25) group, the Danzhong (RN17) group, the Zusanli (ST36) group, the Sanyinjiao ( @entity38337 ) group, the Xinshu (BL15) group, and the Weishu (BL21) group, 10 in each group. The regulatory effects of EA (2/15 Hz, 3 mA, 2 min) at different acupoints on the gastric motility (intragastric pressure) and the cardiac function (the left ventricular pressure) were observed. The mean values of effect of two-min pre-EA and after-EA were compared. RESULTS: Compared with the pre-EA in the same group, the left ventricular pressure decreased in the Neiguan ( @entity16518 ) group, the Quchi (LI11) group, the Danzhong (RN17) group, the Sanyinjiao ( @entity38337 ) group, and the Xinshu (BL15) group (P <0.05). The intragastric pressure increased in the Quchi (LI11) group, the Zusanli (ST36) group, the Sanyinjiao ( @entity38337 ) group, and the Xinshu (BL15) group, while it decreased in the Tianshu (ST25) group, the Danzhong (RN17) group, and the Weishu (BL21) group (P <0.05). The difference of the left ventricular pressure was sequenced from high to low as Xinshu (BL15) >Danzhong (RN17) >Neiguan ( @entity16518 ) >Sanyinjiao ( @entity38337 ) >Quchi (LI11). The difference of the intragastric pressure was sequenced from high to low as Tianshu (ST25) >Weishu (BL21) > Xinshu (BL15) > Danzhong (RN17) > Zusanli (ST36) > Sanyinjiao ( @entity38337 ) > Quchi (LI11). CONCLUSIONS: EA at the same acupoint (2/15 Hz, 3 mA) showed different regulatory effects on the heart and stomach. There existed some difference in the direction and size due to the acupoint location, meridians, dominant nerve segment or relating organs. A fixed effect direction to the specific target was also shown.
