Relationship of IL-6 ,TGF-β,matrix metalloproteinase-7 in peritoneal fluid and endometriosis

Objective To evaluate the expression of IL-6,TGF-β,matrix metalloproteinase-7 (MMP-7) in the peritoneal fluid of different stage of endometriosis (EMs) patients.Methods Peritoneal fluid samples from female without EMs (n =35) and 45 patients with EMs (36 cases with stage Ⅰ,Ⅱ;9 cases with stage Ⅲ,Ⅳ)were obtained for detectionof IL-6,TGF-β,MMP-7byELISA.Results TheconcentrationofIL-6,TGF-β,MMP-7 was (736.5 ± 526.6) ng/L,(936.5 ± 523.5)ng/L and (5.63 ± 1.98) μg/L in EMs patients,which were higher than those in control group (P ＜ 0.01).The concentration of IL-6,MMP-7 was (948.6 ± 485.4) ng/L,(8.69 ± 1.23) μg/L in stage Ⅲ,Ⅳgroup,and (453.6 ± 256.8) rng/L,(4.23 ± 1.08) μg/L in stage Ⅰ,Ⅱ group,there were significant differences between the two groups (P ＜ 0.05).The concentration of MMP-7 was positively correlated with IL-6(r =0.789,P ＜0.01),and was negatively correlated with TGF-β(r =-0.458,P ＜0.05).Conclusion IL-6,TGF-β,MMP-7 may play roles in microecology immune imbalance and the development of EMs. Key words: Endometriosis ;  Peritoneal Lavge;  Matrixmetalloproteinases-7 ;  IL-6 ;  TGF-β
