針刺足三里對健康者餐前與餐後的胃電圖影響

在傳統中醫經絡學說裡，針刺足三里(Zu-San-Li, ST36)是常見於治療為長期病的要穴，然而針灸作用的機理與胃動力活性兩者之關連性依然尚未明確；因此，本研究之目的，在於比較針刺足三里對健康者餐前與餐後的胃電圖影響。在本研究的實驗中，8名年齡介於20到25歲之間的自願受測者，均接受針刺組與對照組之試驗，試驗包括：水試驗、牛奶試驗與固態食物試驗；每項試驗分為餐前與餐後的胃電圖量測，且各三十分鐘；本研究中自行研製一套胃電圖量測系統，並使用主動式濾波器與有限脈衝濾波器將雜訊(如心電圖、呼吸訊號與低頻移動雜訊)濾除，且經過驗證結果可得到正確的胃電圖訊號；再經由移動性頻譜分析的方法，進一步分析每分鐘胃肌電的頻率與功率變化。在本實驗結果中，流質性物質分別在水試驗餐後10分鐘量測，以及牛奶試驗餐後30分鐘量測，比較基於餐前的相對變化期間主功率(100% X 餐後期主功率/餐前期主功率)，針刺組與對照組相比有顯著的增加，表牛奶試驗的針刺作用較水試驗晚；然而針刺組的固態性食物試驗餐後10、20與30分鐘量測中，相對變化期間主頻呈現均勻的減少(分別為108 ± 3.8 %, 105 ± 2.7 % 與98 ± 1.8 %)，且比較對照組，針刺足三里可增加胃排空的頻率。但在流質性物質試驗，相對變化期間主頻呈現非均勻的情況，尤其在牛奶試驗下，其胃動節律過快的比例較對照組顯著性高。在本研究結果中指出，針刺足三里對於胃排空及胃收縮節律性有者增強的效果。

The acupuncture point ST36 (Zu-San-Li) of the lower legs is the common effective point for the treatment of gastric symptoms in Chinese traditional medicine. However, the mechanism of the beneficial effects of acupuncture on gastric motor activity still does not fully understand. Therefore, the aim of this study is to compare the effect of acupuncture between pre- and postprandial on gastric myoelectrical activity in healthy humans. In the experiment, acupuncture group and control group contain eight volunteers whose ages are 20-25 years old. The test included water meal、milk meal and Solid meal. Electrogastrography (EGG) was recording for 30 minutes at fasting period (baseline), and for 30 minutes at after meal. In this study, the recording system can be obtained correct gastric myoelectrical activity. It was use the active filter and digital filter to eliminate noises, which include: ECG, respiration and artificial motion. Furthermore, the running spectral analysis methods further analyze the frequency and power of gastric motility per minute. Our present study, result are demonstrated that acupuncture at ST36 significantly increased PDP in after liquid meal. And that was uniform decrease the relative change of PDF after solid meal 10, 20 and 30 minutes (108 ± 3.8 %, 105 ± 2.7 % and 98 ± 1.8 %, respectively). However, it was not uniform decrease the relative change of PDF after liquid meal 10, 20 and 30 minutes, especially milk meal, and further, that percentage of tachygastria was more than the control group. These findings suggest that acupuncture at ST36 have a enhance effect on gastric emptying and gastric contraction rhythm.
