To summarize the distribution characteristics of TCM syndromes type，syndrome elements，tongue and pulse of non-alcoholic fatty liver disease (NAFLD) based on the clinical researches of traditional Chinese medicine (TCM) of NAFLD. Methods:A total of 77 cases，which were related to TCM syndromes of NAFLD and published on Chinese National Knowledge Infrastructure (CNKI)，Wanfang data，VIP from 2006 to 2017，were evaluated from time，region，the quality of literatures，syndrome type，syndrome elements of disease nature and location，and analyzed with association rule and frequency analysis. Results:1)In recent years，the number of publications related to NAFLD syndrome has been on rising，with the largest number of publications in coastal areas. Cross-sectional studies (57.14%) and case-control studies (31.16%) were the two main types of TCM syndrome literature of NAFLD. Randomized controlled trials (9.10%) and cohort studies (2.60%) were less，and the quality of these were uneven. 2)For analyzing 68 medium and high quality literatures，the main type of NAFLD was syndrome of stagnation of liver qi and spleen deficiency (22.37%)，in turn to syndrome of accumulated dampness-heat (21.96%)，syndrome of phlegm and blood stasis (12.73%)，syndrome of stagnation and blockade of phlegm-damp(8.85%)，syndrome of wet turbidity stop (7.87%) and syndrome of deficiency of liver and kidney (5.80%). 3)The main syndrome elements of disease nature were wet (24.32%)，in turn to qi stagnation (15.38%)，qi deficiency (14.81%) and phlegm (14.22%). The main syndrome elements of disease location were liver (48.12%)，spleen (39.03%)，kidney (12.43%)，gallbladder (0.32%) and stomach (0.10%). Pink tongue，white greasy fur and stringy pulse were the common tongue manifestations and pluses in NAFLD. Conclusion:The NAFLD syndrome type is different in the progress of the disease. In the early stage，it is mainly based on excess，while in the middle stage，it is mixed with deficiency and excess. In the later period，the deficiency of the syndrome is common，and the deficiency and excess are often transformed into each other. The findings indicate that the primary location of disease syndrome factors of NAFLD is liver. Wet，qi stagnation，qi deficiency and phlegm are the key pathogenesis of NAFLD. High level and high quality of studies on NAFLD are insufficient，so it is necessary to carry out multiregional and multi-center large sample of TCM clinical randomized controlled studies or cohort studies，in order to provide evidence basis for TCM syndrome differentiation and treatment of NAFLD.
