摘要
目的观察甲状腺机能亢进患者与正常人三阴交穴伏安特性的变化规律。方法应用自行研制的新一代智能型穴位伏安特性计算机检测系统对甲状腺机能亢进患者与正常人三阴交穴及对照点的伏安特性变化进行观察和分析。结果正常人和甲亢患者穴位的增程、减程伏安面积及惯性面积均小于对照点,同一采样电流点增程电阻均大于减程电阻;甲亢患者减程扫描电阻小于正常人。结论人体电阻呈现明显的非线性特征;增程、减程伏安面积及惯性面积均能灵敏地反映出穴位的特异性;减程电流扫描更能反映出甲亢患者和正常人的差异。
Objective To investigate the regularity of changes in the voltage-ampere characteristic of point Sanyinjiao （ SP 6） in hyperthyroidism patients and normal persons. Methods A new self-developed intelligent voltage-ampere characteristic computer-aided detection system was used to observe and analyze changes in the voltage-ampere characteristics of point Sanyinjiao and a control point in the hyperthyroidism patients and normal persons. Results The range-increasing and range-decreasing voltage-ampere areas and inertia area of the acupoint were all smaller than those of the control point in the normal persons and hyperthyroidism patients. The range-increasing resistance was larger than the range-decreasing resistance in the same sampled current spot. The range-decreasing scan resistance was smaller in the hyperthyroidism patients than in the normal persons. Conclusion Body resistance takes on an obvious nonlinear characteristic. Range-increasing and range-decreasing voltage-ampere areas and inertia area can all sensitively reflect the specificity of acupoints. Range-decreasing scan can more reflect the difference between hyperthyroidism patients and normal persons.
