脑梗死中医“证”的结构方程

The structual Equation of the TCM Syndrome of Cerebral Infarction

目的:为脑梗死临床辨证诊断和证型的量化标准提供参考依据。方法:本研究通过临床大样本多中心现场调研,应用先进的数理统计方法—结构方程对脑梗死中医证候系统的研究。结果:在脑梗死结构方程中各因子与临床证型间存在着较好的对应关系,其共因子为风瘀证、各分因子分别为阴虚、气虚、火热、痰湿证;结构方程各因子间的相互关系揭示了脑梗死各证型之间的标本因果关系以及彼此相互兼夹、转化、演变的规律。结论:脑梗死直接的共同的病理要素是风瘀,而更深一层次的病理机制是阴虚、气虚、火热、痰湿等。表现在临床证候上,风瘀、阴虚、气虚、火热、痰湿既可合并出现,也可单独出现;无论是单独出现还是合并出现,都必然兼夹(或存在)着风瘀证的内容。

Objective： To provide reference evidence for clinical diagnose and quantitative criterion of cerebral infarction. Methods ： The dissertation was a systemic study of TCM syndrome of cerebral infarction through research of large sample and many centers and appliance of advanced mathematical statisticsmeans structual equation. Results： There was better corresponding relation between common factor-ind and blood stasis and others-qi-insufficiency, yin-insufficiency, fire-heat and phlegm-damp syndrome; Their connections opened out rule of cause and effect, translation and evolvement. Conclusions： Common element of cerebral infarction was wind and blood stasis syndrome, others were qi-insufficiency, yin-insufficiency, fire-heat and phlegm-damp syndrome deeply.They appeard not solely but incorporately. No matter what happened, the wind and blood stasis syndrome always existed.
