CD4 and CD8 cell infiltration was evaluated by immunohistochemical assays on frozen sections of the biopsy samples. Fifteen symptoms referring to digestion-related activity and nondigestion related activity were observed. The correlation between lymphocyte infiltration and each symptom or symptom assemblage was analyzed by logistic regression and K-mean cluster methods.RESULTS: CD4 cell infiltrations in gastric mucosa were much more in patients with H pylori infection, while CD8 cell infiltrations were similar in patients with or without H pylori infection. Logistic regression analysis showed that the symptoms including heavy feeling in head or body (t= 2.563), and thirst (t= 2.478) were significantly related with CD4 cell infiltration in gastric mucosa (P＜0.05), and cool limbs with aversion to cold were related with CD8cell infiltration (t = 2.872, P＜0.05). Further analysis showed that non-digestive related symptom assemblage could increase the predicted percentage of CD4 and CD8cell infiltration in gastric mucosa, including lower CD4infiltration by 12.5%, higher CD8 infiltration by 33.3%,and also non-H pylori infection by 23.6%.K-means cluster analysis of all symptoms and CD4 and CD8 cell infiltration in gastric mucosa showed a similar tendency to increase the predicted percentage of CD4, CD8 cell infiltration and H pylori infection.CONCLUSION: Based on correlation between the gastric mucosa lymphocyte infiltration, H pylori infection and clinical symptoms, symptoms or symptomatic assemblages play an important role in making further classification of chronic gastritis, which might help find a more specific therapy for chronic gastritis.展开更多
