Study on distribution regularities of traditional Chinese medicine syndromes of gastroesophageal reflux disease based on factor analysis

Objective To explore the distribution pattern of TCM syndromes of gastroesophageal reflux disease,and to provide evidence for clinical diagnosis and treatment of the disease.Methods Using a pre-designed questionnaire,an epidemiological survey was conducted on 263 patients with gastroesophageal reflux disease who visited the clinic from September 2015 to December 2017.Data such as symptoms,signs and shemai were collected.And a database was established.The common factors were extracted by factor analysis,and explained in combination with Chinese medical knowledge.Results The factor analysis extracted 4 common factors with a characteristic root value of 2.537 and a cumulative contribution rate of 72.959%.And the factors were judged combined with the traditional Chinese medicine syndromes and could be summarized into zhongxu qini syndrome,yuxue zuluo syndrome,ganpi shire syndrome and ganwei discordance syndrome.Conclusion Factor analysis is one of the effective methods to objectively analyze the distribution pattern of TCM syndromes of gastroesophageal reflux disease,and it can provide a basis for the syndrome differentiation and treatment of this disease.
