To investigate the correlation between TCM Pattern of functional dyspepsia and psychological factors.Methods:According to epidemiologic investigation method, 297 patients were selected randomly, subject to psychological evaluation, TCM pattern identification, scoring using SDS and SAS.Results:1) Pattern of spleen deficiency and qi stagnation was most common(32.3%); 2) depression was often seen with liver qi depression (62.5%), while anxiety with liver-qi-invading-stomach (35.8%). Depression and anxiety were comparatively less seen in dampness-heat stagnating-stomach; 3) Post-prandial fullness was common with spleen-stomach qi deficiency and spleen-deficiency qi-stagnation, early satiation with spleen-stomach qi deficiency, upper abdominal pain in liver qi depression and spleen-stomach qi deficiency, upper abdominal burning sensation in dampness-heat stagnating-stomach group; 4) SDS score was highest with liver qi depression group, while SAS score was highest in liver-qi-invading-stomach group. Lowest scores appeared with dampness-heat-stagnating-stomach group. Conclusion:Patients of functional dyspepsia have varied and significant differences in TCM pattern and psychological status, mechanisms of which are deficiency-excess complicated and closely related to liver and spleen.
