The cervical secretions were collected to determine p16, MMP-2, MMP-7 and MMP-9 levels with enzyme-linked immunosorbent assay (ELISA) kit, cervical lesion tissue samples were collected to determine angiogenesis index levels by RIA method, and ELISA kits were used to determine proliferation genes B7-H4, GBP1, Sp2, EZH2 and PKC protein expression. Pearson test was used to analyze the correlation of p16 and MMPs expression in cervical secretions with the angiogenesis and cell proliferation in cervical cancer tissue of patients with cervical cancer.Results: p16, MMP-2, MMP-7 and MMP-9 levels in cervical secretions of observation group were higher than those of control group, and COX-2, VEGFA, VEGFC, B7-H4, Sp2, EZH2 and PKC expression in cervical biopsy tissue were higher than those of control group while GBP1 expression was lower than that of control group.Conclusion:p16 and MMPs expression in cervical secretions of patients with cervical cancer can quantifiably reflect the degree of angiogenesis and proliferation of cervical cancer cells.展开更多
