To study the curative effect of Danxia Zhifang decoction in treating non-alcoholic fatty liver disease of dampness-turbid stagnation syndrome and explore the TCM evaluation idea and treatment.Methods:Using parallell control and random double blind research by dividing the patients of non-alcoholic fatty liver disease into two groups:one takes Danxia Zhifang decoction and the other Qianggan capsule for 3 months.Then observe the main symptoms,CT ratio of liver spleen,ultrasonic examination,liver function and blood fat indexes of the two groups.Results:The total effeciency rate,total effective rate are 40.82% and 62.50% respectively and the total efficiency,total relief rate of TCM syndrome are 51.02% and 91.84% respectively in the treatment group,which are of significant difference compared to those of the control group (P<0.05).Indexes of syndrome integral,main symptoms integral,liver function and blood fat all have significant improvement after treatment (P<0.05).Obvious correlations among indexes of curative effect of disease,relief effect of syndrome,induce of syndrome integral and main efficacy evaluation were observed in the teratment group (P<0.05).Conclusion:Danxia Zhifang decoction has absolute curative effect in treating non-alcoholic fatty liver disease,and it can improve main symptoms,CT ratio of liver spleen,liver function and blood fat.In addition,there are correlations among Danxia Zhifang decoction’s curative effect,TCM syndrome integral,CT ratio of liver spleen and liver function.
