| 摘 要： | 用微机实验系统研究了３２例正常人和４７例上消化道（食道、胃和十二指肠）病例的耳穴体表电位．结果表明，电位变量Ｊ具有区分病变的显著性，Ｐ＜０．０１．Ｊ的概率密度函数定量地描述反应病变的特性，获得临界指标Ｊ０和诊断评价指标的估值均数：特异度Ｓ－ｐ＝０．８４，敏感度Ｓ－ｅ＝０．８１，准确度ｒ－＝０．８２，约登指数ｒ∧－＝０．６５．耳穴电位可能具有较好的诊断应用前景

| Abstract: | We researched electric characteristic of the auricular points between 32 normal persons and 47 cases of Upper Digestive Tract by a micro commpurter experiment system. The result shows: the potential variable J is of significace distinguishing pathologic change, P <0.01. The probability distribution of J can describe the specificity reflecting pathology. We obtained index estimates evaluating differential diagnoses: specificity S - p =0.84, sensitivity S - e =0.81,accuracy r [DD(-*2]-=0.82 and Youden's indexr r ^- =0.65 by the probability funciton of J . The application of the otopoint potential probably will have a bright prospect. |
