Abstract:
Objective To explore the distribution of traditional Chinese medicine basic syndromes in sepsis,and to provide evidence for the establishment of diagnostic criteria of sepsis syndromes.Methods Literatures related to sepsis syndrome included in China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP database(VIP)and Chinese Biomedical Literature Database(CBM)databases were searched from the establishment of the database to May 30,2020.Screen the literature and extract data,establish a database for statistical description and analysis of syndrome elements,basic syndromes and symptoms.Analyze the association rule of syndrome elements based on the Apriori algorithm.Based on the two-step hidden tree analysis LTM-EAST algorithm,a symptom latent structure model was constructed,and a comprehensive cluster analysis and model interpretation were performed.Results A total of 383 articles related to sepsis syndromes were included,involving 31 basic syndromes,146 symptoms and 29 syndromes elements.The basic syndromes with frequencies≥5%and cumulative composition ratios≥75%were heat and toxin syndrome,blood stasis syndrome,Yin deficiency syndrome,heat and closing syndrome,Qi deficiency syndrome,phlegm and heat syndrome,Yang prostration syndrome,Fu-organ excess syndrome,and Yang deficiency syndrome.Perform the association rule analysis on syndrome elements with a frequency＞5,obtaining 8 strong association rules,and inferring 7 basic syndromes,including Fu-organ excess syndrome,heat and toxin syndrome,heat and closing syndrome,phlegm clouding the heart syndrome,heat disturbing the heart spirit syndrome,phlegm and heat syndrome,phlegm block syndrome.The symptoms with frequency＞5 were analyzed by hidden structure,41 hidden variables and 82 hidden categories were obtained,and 11 comprehensive clustering models were obtained through comprehensive clustering.Eleven basic syndromes were inferred,including heat and toxin syndrome,blood stasis syndrome,Yin deficiency syndrome,heat and closing syndrome,Qi deficiency syndrome,phlegm and heat syndrome,Yang prostration syndrome,Fu-organ excess syndrome,Yang deficiency syndrome,Yingfen syndrome,and phlegm-dampness syndrome.Combined with all of methods above,9 basic syndromes,heat and toxin syndrome,blood stasis syndrome,Yin deficiency syndrome,heat and closing syndrome,Qi deficiency syndrome,phlegm and heat syndrome,Yang prostration syndrome,Fu-organ excess syndrome,and Yang deficiency syndrome were finally confirmed.Conclusion There are 9 common basic syndromes of sepsis,and the sufficient syndromes are mainly heat and toxin syndrome,blood stasis syndrome,heat and closing syndrome,phlegm and heat syndrome and Fu-organ excess syndrome,while the deficiency syndromes are mainly Yin deficiency syndrome,Qi deficiency syndrome,Yang prostration syndrome,and Yang deficiency syndrome,with each basic syndrome having certain symptom characteristics.
