ABSTRACT

Objective To study the relation of matrix metalloproteinase-9 in serum and tumor necrosis fac- tor-?in serum and amniotic fluid in predicting ehorioamnhionitis in patients with premature rupture of membranes (PROM).Methods The levels of MMP-9 in serum and TNF-?in serum and amniotie fluid were measured by ra- dioimmunoassay and ELISA in 67 cases with premature rupture of membranes as study group and 40 cases normal full-termed pregnant women as controls group.Results(1)The levels of TNF-?in amniotie fluid and MMP-9 in serum in study group were significantly higher than those in controls group(P0.05).(2)In study group,the levels of MMP-9 of serum in0.05).Conclusions The levels of TNF-?in amniotic fluid and MMP-9 in serum were valuable clinical indices for identification of chorioamnionitis in patients with PROM.The levels of MMP-9 in serum also could assess the time of rupture of membranes and the degree of ehorioamnionitis.
