Methods： In 14 cases of mild ICP, 14 cases of severe ICP and 14 cases of normal cases （control group） with corresponding age and gestation weeks, the expressions of ERa and ERD were detected by means of immunohistochemical method S-P. Results： The mean grey numbers of ERa in each group mentioned above were 151.684±3.76, 149.854±3.69, 153.184±3.18, without significant difference （P〉0.05） The mean grey numbers of ERβ in each group mentioned above were 146.51±3.81, 139.434±9.97, 149.87±4.17, with significant difference （P〉0.05）; the expression of ERI3 of severe ICP group was significantly higher than that of the mild ICP group and the control group （P〈0.05）. The expression of ERβ in every group was higher than that of ERa （P〈0.05）. Conclusion： ERβ maybe play an important part in the etiology and development of ICP展开更多
文摘Objective:To determine whether maternal β-human chorionic gonadotropin(β-hCG) level in second-trimester may be associated with subsequent development of pregnancy-induced hypertension(PIH).Methods:Seven hundred and sixty-two women in mid-trimester were to have maternal urine β-hCG standardized concentrations and maternal serum β-hCG measurements.Their case histories were recorded and reviewed from mid-trimester to delivery.The relation was observed between maternal urine,serum markers and subsequent development of PIH.Results:Among 762 women,504 cases were normal pregnancies,42 cases had PIH,94 cases had premature rupture of membrane (PROM),69 cases had preterm delivery (PD),53 other cases were excluded by various reasons.The levels of maternal urine,serum β-hCG in PIH were (61.75±9.78) IU/L and (304.56±54.17) ng/mg respectively,which were higher significantly than normal pregnancy group ([20.65±7.61] IU/L and [146.34±47.81] ng/mg,P<0.05).When maternal serum,urine β-hCG levels ≥2 MOM(multiple of mean),the incidences of developing PIH were increased significantly as compared with those of β-hCG <2 MOM women.The incidence of PIH increased from 5.1% in pregnancies with urine β-hCG ≥2 MOM to 11.7% in cases with urine β-hCG ≥4 MOM.Conclusion:The elevation of maternal mid-trimester urine,serum β-hCG levels is not only an early signal for dysfunction of placenta but also a dangerous signal for development of PIH.Second-trimester maternal urine β-hCG measurement proves to be superior to serum marker in clinical prediction.
