Doublelabeling staining was used to display the distribution of Bcl-2^＋/ki-67 cells in 162 cases of GC and its matched normal mucosa and precancerous lesion.RESULTS： The positive rate of Bmi-1 expression in GC（52.5%） was significantly higher than that in normal gastric mucosa （21.6%, X^2 = 33.088, P 〈 0.05）. The Bmi-1 expression in GC was closely related with the Lauren＇s and Borrmann＇s classification and clinicalstage （X^2 = 4.400, 6.122 and 11.190, respectively, P〈 0.05）. The expression of ki-67 was related to the Borrmann＇s classification （X^2 = 13.380, P 〈 0.05）.Bcl-2 expression was correlated with the Lauren＇s classification （Z2 = 4.725, P 〈 0.05）, and the Bmi-1 expression both in GC （rk = 0.157, P 〈 0.05） and inintestinal metaplasia （rk = 0.270, P 〈 0.05）.CONCLUSION： Abnormal Bmi-1 expression in GCmay be involved in cell proliferation, apoptosis andcancerization. This marker can objectively indicate theclinicopathological characteristics of GC.展开更多
