Cytotrophoblast invasiveness of normal and PIH placenta was measured by in vitro invasion assay. Effects of IGF-Ⅱand TGF-β1 on cytotrophoblast invasion were also studied.Results: In PIH group, cytotrophoblast invasiveness was dramatically decreased. In normal group, trophoblast invasiveness was significantly enhanced by IGF-Ⅱ but inhibited by TGF-β1. Neither IGF-Ⅱ nor TGF-β1 had statistically significant effects on PIH trophoblast invasion.Conclusions: PIH cytotrophoblast invasiveness dramatically decreases as compared to the normal level. IGF-Ⅱand TGF-β1 may play an important role in shallow trophoblast invasion on PIH.展开更多

METHODS Retrospective study of pregnancy in women with known BCS at single center from January 2001 to December 2015. RESULTS Out of 53 females with BCS, 7 women had 16 pregnancies. Median age at diagnosis of BCS in these women was 25 years(range 21-34 years). At least one causal factor for BCS was identified in 6 women(86%). Six women had undergone radiological decompressive treatment. All patients had anticoagulation. Six fetuses were lost before 20 wk gestation in 2 women. There were 9 deliveries over 32 wk gestation and one delivery at 27 wk. All infants did well. Seven babies were born by emergency caesarean section. There were no cases of thrombosis. Two patients had notable vaginal(PV) bleeding in 3 pregnancies. None of the patients had variceal haemorrhage. Two patients were diagnosed with pulmonary hypertension, one during pregnancyand the other in the post-partum period. There was no maternal mortality.CONCLUSION Maternal outcomes in patients with treated BCS are favourable and fetal outcomes beyond 20 wk gestation are good. There has been increased rate of caesarean section. Pulmonary hypertension is an important finding that needs further validation. These patients should be managed in centers experienced in treating high-risk pregnancies.展开更多

Study Design: A literature search was conducted using MEDLINE, with analysis of 25 studies that recorded neonatal and maternal outcomes in women who used metformin during pregnancy. The outcomes assessed in this review include congenital deformities, miscarriages, preterm labour, gestational diabetes (GDM) and pregnancy induced hypertension (PIH). Results: We found that the use of metformin throughout pregnancy correlated with decreased rates of preterm labour, GDM and PIH. Conflicting evidence exists over whether metformin use during pregnancy reduced miscarriage rates. The use of metformin during pregnancy did not increase teratogenicity risks. Conclusion: The use of metformin throughout pregnancy is associated with decreased rates of preterm labour, GDM, and PIH. However, more randomised controls involving larger numbers of participants are required for more definitive results.展开更多
