心理应激人群肝气郁结证的计量诊断

目的：对心理应激人群中肝气郁结证者进行计量诊断。方法：对心理应激人群中肝气郁结证者以Bayes逐步判别、多元Logistic逐步回归以及频数优势法3种方法,分别结合原诊断标准指标、计算机筛选指标、计算机筛选指标＋原诊断标准指标等不同指标的方式进行量化研究。结果：以Bayes逐步判别法分别以3种指标筛选法,建立了3种判别模式,其判别符合率均在92.7%以上,敏感度均在90.2%以上,特异度均在94.6%以上;以Logistic逐步回归法分别以3种指标筛选法,建立了3种回归模型,其诊断判别符合率均在92.4%以上,敏感度均在92.7%以上,特异度均在92.2%以上。结论：上述方法及指标不同组合所建立的对肝气郁结证的诊断或判别模式均具良好的诊断判别效果。

Quantitative Diagnosis of Liver-Qi Stagnation Syndrome in Crowd of Psychological Stress

Objective：To study liver-Qi stagnation syndrome in crowd of psychological stress with quantitative diagnosis.Methods：Combining with the original indexes of diagnostic criteria,indexes screened by computer and indexes bonding the two kinds of above,we use three kinds of methods as Bayes stepwise discriminant,Logistic regression and priorities of frequencies to study the quantization of liver-Qi stagnation syndrome in crowd of psychological stress.Results：Use screening methods of three indexes to establish three kinds of discriminative modes with the Bayes stepwise discrimminant and the coincidence is more than 92.7 percent,the sensitivity is more than 90.2 percent,the specificity is more than 94.6 percent. Use screening methods of three indexes to establish three kinds of regression model with Logistic regression and the coincidence is more than 92.4 percent,the sensitivity is more than 92.7 percent,the specificity is more than 92.2 percent.Conclusion：the diagnostic or discriminative modes of liver-Qi stagnation syndrome erected by different combinations between the above-mentioned methods and indexes have favorable diagnostic and discriminative effects.
