Subacute, Research Into Correlation Between Tcm Syndrome Types And Causes Of Chronic Cough

Objectives:This dissertation involved the various clinical survey results, the existence of co-relationship between TCM syndrome type and the western medicine etiology was proved with relatively effective statistic approach. The results obtained from this research could provide useful information for further investigation on the clinic.Methodology:The Prospective study was conducted in this research. It covered219local cough patients, whose course of cough was from3to96weeks. Their main symptom, concomitant symptoms, general condition, the tongue and pulse condition were investigated accordingly. Through the statistical software analysiste, it came to the final conclution of the correlation between TCM syndrome type and the western medicine etiology.Results and Discussions:1. Subacute and chronic cough:results showed that cough post infection (CPI)(37.9%) is the main cause, followed by the cough variant asthma (CVA)(27.9%), the upper-airway cough syndrome (UACS)(14.6%). Among them, in subacute cough (the course of3-8weeks), the percentage of CPI was more than50%. In chronic cough (the course of more than8weeks), CPI accounted for32.5%, CVA accounted for31.8%, both accounted for about two-thirds causes of chronic cough.2. Most subacute and chronic cough belonged to internal injures cough in TCM. The distribution rate of patients mentioned above in TCM syndrome type followed the descending order which was:phlegmy heat implication> phlegmy wet resistance lung> Liver-yang hyperacticity> pathogenic wind invading the lung> Lung Yin deficiency. Among them, the order of the course between3to8weeks was:phlegmy heat implication>phlegmy wet resistance lung> Liver-yang hyperacticity> pathogenic wind invading the lung, the syndrome type of Lung Yin deficiency was not existed; The order of the course which was more than8weeks was:phlegmy wet resistance lung> phlegmy heat implication> Liver-yang hyperacticity> pathogenic wind invading the lung> Lung Yin deficiency. It indicated the "phlegm" was the main pathogenic factor; heat evil played an important role in the disease outcome, and wind evil had a dramatic impact in some cases.3. The TCM syndrome type, pathogenic wind invading the lung (P<0.0001) was correlated with CVA; four TCM syndrome types, phlegmy heat implication (P value=0.03), phlegmy wet resistance lung (P value=0.04), pathogenic wind invading the lung (P value=0.002), Lung Yin deficiency (P value=0.01) were correlated with CPI; There were no evidence to prove that UACS was associated with any TCM syndrome type.Conclusions:There are co-relationship between the western medicine etiology and the TCM syndrome type in the subacute and chronic cough. The co-relationship of common western medicine etiology and TCM syndrome type was:CVA with pathogenic wind invading the lung, CPI with four TCM syndrome types of phlegmy heat implication, phlegmy wet resistance lung, pathogenic wind invading the lung and Lung Yin deficiency.
