摘要
目的从计量诊断学的角度研究腹泻型肠易激综合征(diarrhea-predominant irritable bowel syndrome,IBS-D),构建IBS-D中医证候的判别函数,以降低IBS-D中医证候诊断和鉴别诊断中的主观因素干扰。方法采用《肠易激综合征临床信息采集表》对439例IBS-D患者进行中医临床流行病学调查,运用聚类分析获取初始证候,以四诊信息和患者血清脑肠肽为变量,运用逐步判别法进行分析。结果聚类为肝郁脾虚证、脾胃虚弱证、肝郁气滞证、脾肾阳虚证、脾胃湿热证和寒湿困脾证,其中肝郁脾虚证最多,有效百分比为34.2%,寒湿困脾证最少,有效百分比为5.5%;逐步法所得肝郁脾虚证、脾胃虚弱证、肝郁气滞证、脾肾阳虚证及脾胃湿热证5个判别函数,回顾性误判概率4.1%(16/390),交叉验证误判率为15.4%(60/390)。结论建立的判别函数,对ISB-D的中医证候的客观诊断及鉴别诊断有一定的参考价值。
Objective To establish discriminant functions of diarrhea-predominant irritable bowel syndrome(IBS-D) by studying it from quantitative diagnosis angle,hoping to reduce interference of subjective factors in diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.Methods A Chinese medical clinical epidemiological survey was carried out in 439 IBS-D patients using Clinical Information Collection Table of IBS.Initial syndromes were obtained by cluster analysis.They were analyzed using step-by-step discrimination by taking information of four Chinese medical diagnostic methods and serum brain-gut peptides(BGP) as variables.Results Clustering results were Gan stagnation Pi deficiency syndrome(GSPDS),Pi-Wei weakness syndrome(PWWS),Gan stagnation qi stasis syndrome(GSQSS),Pi-Shen yang deficiency syndrome(PSYDS),Pi-Wei damp-heat syndrome(PWDHS),colddamp disturbing Pi syndrome(CDDPS).Of them,GSPDS was mostly often seen with effective percentage of 34.2%,while CDDPS was the least often seen with effective percentage of 5.5%.A total of 5 discriminant functions for GSPDS,PWWS,GSQSS,PSYDS,and PWDHS were obtained by step-by-step discrimination method.The retrospective misjudgment rate was 4.1%(16/390),while the cross-validation misjudgment rate was 15.4%(60/390).Conclusion The establishment of discriminant functions is of value in objectively diagnosing and differentially diagnosing Chinese medical syndromes of IBS-D.
