Cluster analysis of traditional Chinese medicine syndrome on craniocerebral injury

Objective To explore the main clinical characteristics of traditional Chinese medical syndromes and TCM syndrome type distribution law of craniocerebral injury. Methods Four diagnostic information of the craniocerebral injury patients was recorded with a TCM syndrome questionnaire,then the information database was established,the symptom frequency and cluster analysis of different syndromes were studied. Results Those symptoms of dim complexion,ecchymosis and cyanosis of skin,dark red or purple lips,pachylosis,cough up phlegm or phlegm in throat,dry stool,pale tongue and fine pulse appear ≥30% among the two groups of craniocerebral injury patients. The severe craniocerebral injury patients in acute stage can be divided into one group: type of orifices confused by phlegm and blood stasis. Those patients in recovery stage can be divided into two groups: type of orifices confused by phlegm and heat,type of orifices confused by phlegm with Qi and blood deficiency. The non- severe craniocerebral injury patients in acute stage can be divided into two groups: type of blood stasis and heat evil disturbance,type of blood stasis with deficiency of both Qi and Yin. Those patients in recovery stage can be divided into three groups: type of orifices confused by phlegm- damp with Qi deficiency,type of collaterals obstruction by blood stasis,and type of Qi and blood deficiency. Conclusion Hierarchical cluster analysis could contribute to study the main clinical characteristics of TCM syndromes,identify TCM syndrome type distribution law and provide certain scientific basis for Chinese medicine treatment of craniocerebral injury.
