Study on the Traditional Chinese Medicine Syndrome of Central Airway Malignant Tumor Based on Principal Component Analysis and Cluster Analysis
Objective To analyze the characteristics of TCM syndrome of central airway malignant tumor and explore the distribution pattern of TCM syndrome types.Methods The information of four TCM consultations of 298 patients with central airway malignant tu-mor was collected,and the characteristics of TCM syndrome elements of central airway malignant tumor were determined by using principal component analysis,combined with the criteria for determining evidence elements,and then the entries were clustered by ap-plying systematic cluster analysis to explore the distribution pattern of TCM syndrome patterns of central airway malignant tumor.Re-sults The evidence elements of central airway malignant tumor were mainly phlegm turbidity,qi deficiency,phlegm heat,blood stasis and damp heat.The results of cluster analysis showed that the TCM typology of central airway malignant tumor was dominated by ini-tial syndrome of phlegm heat(35.6％),with the rest being phlegm heat with deficiency of lung and kidney qi(33.6％),syndrome of yang deficiency of spleen and kidney(5.3％),and cold dampness with blood stasis syndrome(4.0％).Conclusion Central airway malig-nant tumor is mainly located in the lung,which is intermingled deficiency and excess syndrome,and asthenia in origin and asthenia in superficiality syndrome.They can be clinically classified as deficiency of lung and kidney qi,phlegm heat with deficiency of lung and kidney qi,cold dampness with blood stasis syndrome,syndrome of yang deficiency of spleen and kidney.
