ABSTRACT
Study on the characteristics of Chinese materia medica (CMM) for treating liver disease in CMM standard based on data mining and theory of syndrome differentiation and treatment. To analyze the prescriptions of oral Chinese patent medicine (CPM) for liver disease treatment of China Pharmacopoeia, China Pharmacopoeia·Clinical Medication Notice [2010 edition (CMM vol.)] and Drug standard of Ministry of Health of the People's Republic of China; Excel statistical analysis software was used to frequency analysis, using SAS 9.1 statistical analysis software as a data mining platform to carry out the association rules analysis. In 114 prescriptions for the treatment of liver disease, 246 herbs were involved. A cluster analysis was used to analyze 27 herbs with high frequency ( ≥ 10) of usage, which were classified into nine clusters including complement virtual medicine, medicine for regulating qi, promoting blood circulation to remove blood stasis, antipyretic, diuretics for eliminating dampness drugs, cathartic, and astringent drug. Eighteen pairs of herbs and 20 pairs of three herbs for oral CPM for liver disease treatment were obtained by association rule analysis. Combined with the characteristics of disease medication. the data mining and the theory of syndrome differentiation and treatment can help to interpret the law and characteristics of CMM in the treatment of liver disease.
ABSTRACT
Objective To explore the regularities and rules of compound herbal formulae for nonalcoholic fatty liver disease (NAFLD).Methods Compound herbal formulae on NAFLD published in journals of CNKI (1979.1-2014.1), VIP (1989.1-2014.1) and CBMdisc (1979.1-2014.1) were analyzed with association rule, frequency analysis and cluster analysis.Results In 107 prescriptions, 179 herbs were involved, and frequency of usage of those herbs was 1499. A cluster analysis was used to analyze 37 herbs with high frequency (≥10) of usage, which were classified into 9 clusters including promoting circulation, clearing heat herb, diuretic herb, food stagnation herb, regulating qi herb, phlegm-resolving herb, qi tonics herb, yin-nourishing herb, qi-activating herb and purgating herb. 30 pairs of herbs and 33 rules for NAFLD were obtained by association rule analysis.Conclusion It was a point of view to understand the regularities and rules of Chinese herb prescription on NAFLD by data mining.
