慢性阻塞性肺疾病中医辨证分型模式研究初探

目的研究慢性阻塞性肺疾病(COPD)中医辨证分型标准及证型分布规律。方法通过大样本临床流行病学/DME的前瞻性调查,采集了616例COPD患者86个相关中医四诊信息变量及肺功能、生活质量等客观指标;借助现代数理统计学工具,以聚类分析、因子分析、方差分析、频数分析为主,在相关专家参与下,拟定COPD的中医临床辨证模式;探索性分析各证型临床分布规律及与肺功能、生活质量的关系。结果初步拟定COPD临床辨证分型模式(6个证型):肺气虚型、风寒袭肺型、肺脾气阴两虚型、肺肾阴虚型、痰饮伏肺兼肝郁脾虚型、痰瘀交结兼心肾阳虚型。证型间存在一定的兼加规律;随着病程发展,证型特征存在一定的演变规律。证型与肺功能、生活质量关系存在规律性。结论初步拟定了COPD辨证标准;临床证型分布及证型与肺功能、生活质量关系显示出一定的规律性,对COPD临床实践及证型规范化研究有一定的参考价值。

Preliminary Study of the Mode of Typing According to Syndrome Differentiation of Chronic Obstructive Pulmonary Disease

Objective To study general law of typing according to syndrome differentiation of Chronic Obstructive Pulmonary Disease (COPD). Method Based on large sample prospective Clinical Epidemiology investigation, symptoms, conditions of tongue, pulse according to TCM and pulmonary function, quality of life in 616 patients of COPD were collected. By means of Frequencies procedure, factor analysis, cluster analysis and analysis of variance in SPSS11.5, analyze the investigated data and lay difficient types of syndrome of COPD according to TCM. Meanwhile, explored distinct distribution and the relation between types of syndrome and pulmonary function, quality of life in patient5 with COPD. Result There were six types according to syndrome differentiation of COPD, deficiency of lung-qi, pathogenic wind-cold attacking lung, deficiency of pulmonosplenic both vital energy and yin, yin-deficiency of the lung and kidney, stagnation of phlegm and pathogenic fluid-reteneion in lung following splenic asthenia and stagnation of liver-qi, blood stasis-phlegm following deficiency of heart-yang and kidney-yang. There were multiple types of syndrome in COPD patients, the relation was detected between each type of syndrome and lung function, quality of life. Conclusion To draw assistance from clinical epidemiology and mathematical statistics method, the initial standard of differentiation of symptoms and signs to COPD was layed. The regularity of types of syndrome to COPD was detected. The result could be used in diagnosis of COPD, and the method could be communicated in the standardization research of syndrome differentiation.
