Abstract:
Objective To investigate the effect of placenta derived tumor necrosis factor (TNF)-α and myostatin (MSIN) in patients with preeclampsia (PE) and fetal development.Methods One hundred and twenty pregnant women who delivery from October 2008 to October 2013 were enrolled in this study.In them,40 healthy pregnant women was normal control group,40 PE and fetal growth in normal pregnant women was PE group,40 PE and fetal growth restriction (FGR) of pregnant women was PE + FGR group.The immunohistochemical localization of SABC method was used to detect for TNF-α and MSIN protein in placenta tissue in each group respectively.Real-time fluorescent quantitative PCR and Western blotting were used to detect for TNF-α and MSIN mRNA and protein in placenta tissue.Results The TNF-α mainly located in placental blood vessels surrounding stroma,decidual cells,trophoblastic cells and MSIN mainly located in placental blood vessels surrounding stroma,decidual cells and terminal villi.The TNF-α and MSIN mRNA expression quantity in PE group was 3.65 ±0.86,1.80 ±0.32 ; in PE + FGR group was 3.88 ± 0.71,2.01 ± 0.55 ; in normal control group was 1.32 ± 0.21,0.77 ± 0.39.The TNF-α and MSIN mRNA expression quantity in PE group and PE + FGR group were significantly higher than those in normal control group(P < 0.01),and there were significant differences between PE group and PE + FGR group(P < 0.05).The TNF-α and MSIN protein expression in normal control group was 0.56 ±0.13,1.31 ± 0.23;in PE group was 1.67 ±0.25,1.55 ±0.34 ;in PE + FGR group was 2.78 ±0.41,3.07 ±0.51.The TNF-α and MSIN protein expression in PE group and PE + FGR group were significantly higher than those in normal control group(P < 0.01),and there were significant differences between PE group and PE + FGR group(P < 0.05).Conclusions The placenta derived TNF-α and MSIN have more important roles in the pathogenesis of PE and normal development of fetal.It can provide coping strategies by detecting the level of placenta derived TNF-α and MSIN.
