RESUMEN

Objective Based on gender differences,this paper discusses the characteristics of facial color diagnosis in male and female patients with metaplastic chronic atrophic gastritis(CAG),and explores the pathological mechanism of different gender patients from the perspective of TCM pathogenesis,so as to provide personalized reference for TCM prevention and treatment of metaplastic CAG.Methods In this study,the complexion information of patients with chronic non atrophic gastritis(CNG)and CAG was collected by MT-BX-01 four-diagnostic instrument.The color colorimetric characteristics of male and female metaplastic CAG patients and CNG patients were analyzed by case-control study.Results In female patients,the L value and a value of liver region in CAG with mild intestinal metaplasia(IM)group,moderate and severe IM were significantly lower than those in CNG group(P<0.05).In male patients,the L value of spleen region in CAG with moderate and severe IM group was significantly higher than that in CNG group(P<0.05).Conclusion There is a certain gender difference in the facial color characteristics of patients with metaplastic CAG.The facial chromaticity value of female patients with metaplastic CAG changes most significantly in the liver area,while that of male patients mainly in the spleen area.It is suggested that the incidence of female metaplastic CAG is mostly related to liver,while that of male is mostly related to spleen,which provides a personalized method for clinical diagnosis and treatment of metaplastic CAG based on gender differences.
