ABSTRACT

Objective To explore the changes and clinical significance of serum syndecan-1 and MMP-9 levels in patients with different stages of endometriosis (EMS).Method 89 patients diagnosed as EMS and meeting criterions were collected from Jul.2014 to Aug.2016 in our hospital,including 20 cases of stage Ⅰ,27 cases of stage Ⅱ,28 cases of stage Ⅲ,and 19 cases of stage Ⅳ.At the same time,42 healthy women in our hospital were selected as control group.General information of the two groups was comparable.The serum syndecan-1 and MMP-9 levels of EMS group and the control group were detected by ELISA in fasting state.Results The serum syndecan-1 and MMP-9 levels of EMS group were higher than those of the control group(P＜0.05).The serum syndecan-1 and MMP-9 levels increased significantly with the increase of EMS stage (P＜0.05).The serum syndecan-1 and MMP-9 levels of EMS group had no significant difference at proliferative phase and secretory phase (P＞0.05).The levels of serum syndecan-1 (r=0.832,P=0.000) and MMP-9 (r=0.764,P=0.000) were positively correlated with EMS stage.There was a positive correlation between serum syndecan-1 and MMP-9 (r=0.684,P=0.000).Conclusion Serum soluble syndecan-1 and MMP-9 show high levels in patients with EMS,and the serum levels are not related to the menstrual cycle.They may be involved in the pathogenesis and progression of EMS through synergistic effects.
