RESUMEN
【Objective】 To establish preliminary diagnostic criteria of spleen-stomach damp-heat syndrome (SDS) in chronic superficial gastritis (CSG) by disease-syndrome combined differentiation method and modern epidemiological method. 【Methods】 A clinical questionnaire of SDS in CSG was drafted out based on literatures study and experts' survey. Questionnaire investigation was performed in 146 cases of CSG, which consisted of 81 SDS cases and 65 nonSDS cases. Mter the investigation, discriminant analysis was adopted to set up the discriminant functional equations and to perform frequency analysis. According to the results, the diagnostic criteria and the simplified diagnostic criteria of SDS in CSG were established. 【Results】 The preliminary diagnostic criteria of SDS in CSG were as follows: (1) the major symptoms were characterized as yellow and greasy tongue fur, fullness or distension or pain in the stomach, loose stool and poor appetite; (2) the secondary symptoms were characterized as bitter taste and sticky mouth, chest depression, thirst but unwilling to drink, fatigue and nausea; (3) diagnosis could be confirmed by the existence of yellow and greasy tongue fur accompanied by either 2 of the other major symptoms, or by either 1 of the other major and 2 of the secondary symptoms, or by more than 3 of the secondary symptoms. The simplified diagnostic criteria were characterized the co-existence of yellow and greasy tongue fur and fullness or distension or pain in the stomach. 【Conclusion】 The preliminary diagnostic criteria of SDS in CSG are scientific, objective and practicable to some extent.
