To investigate the correlation between dampness，heat of pattern elements of disease nature and pattern elements of disease location in damp-heat pattern of chronic gastritis，and to provide reference for clinical diagnosis and treatment.Methods:A total of 312 cases of chronic gastritis with damp-heat pattern were selected by the method of pattern differentiation，and the relationship between dampness，heat of pattern elements of disease nature and pattern elements of disease location in damp-heat pattern was discussed.Results:The distributed feature of the frequency of pattern elements of disease location in 312 cases of chronic gastritis with damp-heat pattern in descending order was：stomach>spleen>liver>kidney>lung>gallbladder; the distributed feature of the correlation coefficient between dampness and pattern elements of disease location in internal organs in descending order was：spleen>stomach>liver>kidney>gallbladder>lung.The results showed that there was a significant correlation between dampness and spleen，stomach and liver (P<0001)，and there was no correlation between the kidney，gallbladder and lung (P>0005).The distributed feature of the correlation coefficient between of heat and pattern elements of disease location in internal organs in descending order was：liver>gallbladder>stomach>spleen>lung>kidney.The results showed that there was a correlation between heat and liver，gallbladder，stomach and spleen (P<0005)，and there was no correlation between lung and kidney (P<0005).Conclusion:Damp-heat pattern is an important pattern type of chronic gastritis，and the dampness and heat of pattern elements of disease nature are related to the stomach，spleen and liver.
