电针不同穴位对低张力胆囊动力学影响的时效规律初步观察

目的：比较电针阳陵泉、阳陵泉配胆囊穴对慢性炎性低张力胆囊动力学影响的时效规律。方法：B超测定电针前即时及电针60 min内第5 min、10 min、20 min、30 min、40 min、50 min、60 min的胆囊体积，描记电针对胆囊动力学影响的时效规律曲线。结果：两组穴位均表现为电针的最初20 min内胆囊体积呈舒张性变化，在随后的20 min内又有1次较明显的舒缩运动，时间效应明显（ P＜0．05），但交互作用未显示统计学差异（P＞0．05）。结论：电针远端穴治疗慢性胆囊炎时，留针时间以40 min为宜，治疗频次以每天2次为宜，阳陵泉穴与胆囊穴不宜同时取用。

Effect of Electroacupuncture at Different Acupoints on the Dynamics of Low Tension Gallbladder

Objective：To compare the effect of electroacupuncture at Yanglingquan and Yanglingquan matching with Dannang point on chronic cholecystitis patients with low tension gallbladder .Methods：The gallbladder vol-umes at different time points （ immediately before electroacupuncture , after 5 minutes,10 minutes,20 minutes, 30 minutes,40 minutes,50 minutes,60 minutes） were measured by B-ultrasonography, and then the curves of time-effect rule were traced out .Results：The two groups showed that the gallbladder volumes had changed in diastole in the first 20 minutes, and there was an apparent diastolic movement in the second 20 minutes, and time effect was significant（P＆lt;0.05）,but the interaction had no statistical difference （P＆gt;0.05）.Conclusion：When acupuncturing the distal points ,the best time of retaining needle is 40 minutes, and acupuncture frequen-cy should be twice a day .Yanglingquan and Dannang points should not be used at the same time .
