小儿肺炎中医证候演变规律研究

目的:探讨小儿肺炎的中医证候演变规律.方法:将纳入病例根据证候表现分为风热犯肺证、痰热壅肺证、阴虚肺热证和肺脾气虚证.跟踪观察患儿在入院当天(基线点)、用药后3、5、7、10天的临床表现,确定各观察点中医证型.应用证候演变概率法对小儿肺炎中医证候在不同观察点、不同地域的演变规律进行系统分析.结果:小儿肺炎初期以风热闭肺证、痰热壅肺证为主;中期是由实证向虚证转移的关键时期;后期应注意固护阴液.小儿肺炎初期,南北方证型分布无明显差异;后期南北方虚证分布差异明显,北方阴虚肺热证多见,南方肺脾气虚证居多.结论:小儿肺炎中医证候在不同观察点、不同地域有着不同的演变规律.

Study on the Evolutional Law of TCM Syndromes of Infantile Pneumonia

Objective:To study on the evolutionat law of TCM syndromes of infantile pneumonia.Methods:The patients enrolled were divided into wind-heat attacking the lung syndrome,accumulation of phlegm-heat in the lung syndrome,Yin-deficiency and lung- heat syndrome and lung and spleen Qi-defieiency syndrome.Clinical manifestations of the patients at the day of admission(basal point),and 3rd,5th,7th,10th day after medication were observed and the TCM syndromes were determined.The evolutional law of TCM syndromes of infantile pneumonia at different observation points and different regions were systematically analyzed by probability of syndrome evolution.Results:Infantile pneumonia at initial stage was mainly wind-heat attacking the lung syndrome,accumulation of phlegm-heat in the lung syndi-ome;metaphase was a key stage transforming from excessive syndrome to deficiency syndrome;at late stage reinforcing and protecting Yin liquid should be paid great attention.At the initial stage there was no significant difference between the north and south region in distribution of syndrome type;at the late stage there was significant difference between the north and south region,Yin-deficiency and lung-heat syndrome was more frequently occured in the north,and lung and spleen Qi-deficiency syndrome was more frequently occured in the south.Conclusion:TCM syndromes of infantile pneumonia has different evolutional laws at different observation points and in different regions.
