Objective To investigate the relationship between COX-2 and Ki-67 proliferation index, bax, microvascular density(MVD)and CD44v6 respectively. Methods The expression of COX-2,Ki-67, bax, MVD (labelled by CD34) and CD44v6 were examined by immunohistochemistry PV method and tissue chip method in 101 cases of cervical carcinomas epithelium. Results The expression of COX-2 in cervical carcinomas has positive correlation with Ki-67, MVD and CD44v6, but has no correlation with bax. Conclusion The probable mechanisms are related with neovascularization, cell proliferation and cell adherence, but not related with the expression of bax.
