The effect of acupuncture at the acupoints of 12 meridians on gastrointestinal and cardiac electricity in healthy adults was studied. Specific regulation between meridian points and viscera was also investigated. An electrogastrogram (EGG), electrointestinogram (EIG), carotid pulse graph, phonocardiogram and electrocardiogram were obtained in 30 healthy adults before and after acupuncture at various acupoints of 12 meridians. The effects of acupuncture on the amplitude and frequency of the EGG, EIG, pre-ejection period and the left ventricular ejection time were then analyzed. Acupuncture revealed that LR3 decreased the amplitude of the EGG while LI11 (Quchi), SJ5 (Waiguan), ST36 (Zusanli), SP9 (Yinlingquan) and SI6 (Yanglao) increased the amplitude. Multiple comparisons among the latter five acupoints indicated that there were significant differences between SP9, LI11, SJ5 and ST36 (p < 0.01, p < 0.01, p < 0.05) and SI6, LI11 and SJ5 (p < 0.01, p < 0.05). SP9 effected EGG amplitude the most, followed by SI6, ST36, SJ5 and LI11. Four acupoints increased the amplitude of the EIG (p < 0.05), including HT5 (Tongli), GB34 (Yanglingquan), SP9 and SI6. No significant differences were observed between these acupoints, but SI6 showed the most obvious effect on EIG amplitude, followed by GB34, SP9 and HT5. No significant effects on the frequency of the gastrointestinal slow wave or on cardiac function indexes were observed. Effects were observed, however, on pre-ejection period and left ventricular ejection time. Routine acupuncture had no detrimental effects on the stomach, intestine and heart in healthy adults, but instead regulated physiological function within a normal range. These findings demonstrate the existence of specific connections between the meridian points and the viscera. The results suggest that multiple meridians control the same viscus, and the same meridian can regulate the functions of multiple viscera.
研究了针刺健康成年人十二经脉穴位对胃肠电和心电的影响。同时还探讨了经穴与脏腑之间的特异性调节关系。对30名健康成年人在针刺十二经脉各穴位前后分别进行了胃电图（EGG）、肠电图（EIG）、颈动脉脉搏图、心音图和心电图检查。然后分析针刺对EGG、EIG的幅值和频率、射血前期及左心室射血时间的影响。针刺结果显示，太冲（LR3）降低了EGG的幅值，而曲池（LI11）、外关（SJ5）、足三里（ST36）、阴陵泉（SP9）和养老（SI6）则增加了EGG的幅值。后五个穴位之间的多重比较表明，SP9、LI11、SJ5与ST36之间存在显著差异（p < 0.01，p < 0.01，p < 0.05），SI6、LI11与SJ5之间也存在显著差异（p < 0.01，p < 0.05）。SP9对EGG幅值的影响最大，其次是SI6、ST36、SJ5和LI11。四个穴位增加了EIG的幅值（p < 0.05），包括通里（HT5）、阳陵泉（GB34）、SP9和SI6。这些穴位之间未观察到显著差异，但SI6对EIG幅值的影响最为明显，其次是GB34、SP9和HT5。未观察到针刺对胃肠慢波频率或心功能指标有显著影响。然而，观察到针刺对射血前期和左心室射血时间有影响。常规针刺对健康成年人的胃、肠和心脏无不良影响，反而在正常范围内调节生理功能。这些发现证明了经穴与脏腑之间存在特异性联系。结果表明，多条经脉可支配同一脏腑，而同一条经脉可调节多个脏腑的功能。
