Abstract: OBJECTIVE To explore the distribution law， characteristics and clinical factors of traditional Chinese medicine (TCM) syndrome types in patients with non-alcoholic fatty liver disease (NAFLD). METHODS 249 patients with NAFLD were enrolled in the study， and their syndrome differentiation was divided into five types: damp-turbidity stagnation syndrome， liver depression and spleen deficiency syndrome， accumulation of damp-heat syndrome， obstruction of phlegm and stasis syndrome and spleen-kidney deficiency syndrome. To explore the correlation between TCM syndrome types， age， gender， BMI and blood purification indicators. RESULTS ①Proportion of syndrome types: damp-turbidity stagnation syndrome accounting for 30.1%， 28.1% for liver depression and spleen deficiency syndrome， accumulation of damp-heat syndrome 25.7%， obstruction of phlegm and stasis syndrome 8.8%， spleen-kidney deficiency syndrome 7.2%.②The ratio of male to female was about 1.39∶1. The patients with accumulation of damp-heat syndrome and damp-turbidity stagnation syndrome were mainly male (P<0.05); those with liver depression and spleen deficiency syndrome were mainly female (P<0.01). ③The alanine transaminase (ALT) elevation in the accumulation of damp heat syndrome was the most significant， and there was statistical difference compared with that of patients with damp-turbidity stagnation syndrome and the liver depression and spleen deficiency syndrome group (P<0.05). The total cholesterol (TC) elevation was the most significant in the damp-turbidity stagnation syndrome， and there was a statistical difference compared with the liver depression and spleen deficiency syndrome， accumulation of damp-heat syndrome， and spleen-kidney deficiency syndrome group (P<0.05). CONCLUSION The most common TCM syndrome types of NAFLD are damp-turbidity stagnation syndrome， liver depression and spleen deficiency syndrome and accumulation of damp-heat syndrome. The male incidence rate is higher than that of female; accumulation of damp-heat syndrome is more liable to induce ALT injury; damp-turbidity stagnation syndrome is more likely to cause TC elevation.
