基于隐树模型的绝经后骨质疏松性骨折证候要素提取及特征分析

Extraction and characterization of syndrome factors of postmenopausal osteoporotic fracture based on latent tree model

目的:提取绝经后骨质疏松性骨折的中医证候要素,分析其相关特征。方法:基于隐树模型,对北京、上海两地社区绝经后骨质疏松性骨折患者中医证候要素相关数据进行分析。结果:发现该病患者主要涉及的证候要素靶位包括:肝、肾(隐变量Y1),脾、肾(隐变量Y2),主要证候要素为肝肾阴虚(隐变量Y1)和脾肾阳虚(隐变量Y2)。结论:隐树模型可以通过绝经后骨质疏松性骨折症状间的复杂关系,定性、定量化地凝练该病中医证候要素,为进一步研究该病提供工作基础与必要条件。

Objective：To extract the TCM syndrome factors of postmenopausal osteoporotic fractures and analyze their related characteristics.Methods：The data of TCM syndromes of postmenopausal osteoporotic fractures in Beijing and Shanghai were analyzed based on the latent tree model.Results：The results showed that the target factors of the syndromes mainly included：liver and kidney（hidden variable Y1）,spleen and kidney（hidden variable Y2）.The main syndromes were yin deficiency of liver and kidney（hidden variable Y1） and yang deficiency of spleen and kidney（Hidden variable Y2）.Conclusion：The latent tree model can qualitatively and quantitatively condense the TCM syndromes of the disease through the complex relationship between postmenopausal osteoporotic fractures,and provide the working basis and necessary condition for the further study of the disease.
