摘　　要：目的:观察阻断前臂血行对内关和太渊穴伏安特性的影响,研究穴位功能、人体气血与穴位伏安特性之间的关系。方法:应用智能型穴位伏安特性检测系统,检测23名健康受试者在阻断左臂或右臂血行前后,同侧内关及太渊穴伏安特性的变化。结果:血行阻断状态下内关及太渊穴增程伏安面积、减程伏安面积均显著大于正常状态(P<0.05,P<0.01),且内关穴增程伏安面积、减程伏安面积变化率均显著大于太渊穴(均P<0.05);血行阻断状态下内关穴惯性面积大于其正常状态(P<0.01),而太渊穴惯性面积变化均无统计学意义(P>0.05)。结论:内关和太渊穴的伏安特性变化能反映机体局部血供改变,内关穴对血液流行状态的改变比太渊穴更敏感。Objective To observe the effects of forearms devascularization on the volt-ampere（V-A） characte-ristics of Neiguan（PC 6） and Taiyuan（LU 9） so as to investigate the relationship among functions of acupoints,qi and blood in human body and V-A characteristics of acupoints.Methods Either forearms of 23 healthy volunteers were devascularized and the changes of V-A characteristics in ipsilateral Neiguan（PC 6） and Taiyuan（LU 9） in normal and devascularization statuses were detected by home-made intelligent V-A detecting system.Results Compared with the normal status,both range-increasing and range-decreasing V-A areas of Neiguan（PC 6） and Taiyuan（LU 9） were significantly increased in devascularization status（P0.05,P0.01）,and the change rates of these two V-A areas of Neiguan（PC 6） were larger than those of Taiyuan（LU 9）（both P0.05）.The inertia areas of Neiguan（PC 6） but not Taiyuan（LU 9） became significantly larger after devascularization（P0.01）.Conclusion The changes in V-A characteristics of Neiguan（PC 6） and Taiyuan（LU 9） can reflect the alteration of local blood supply,and Neiguan（PC 6） is more sensitive to changes of blood flow than Taiyuan（LU 9）.
