水通道蛋白1和水通道蛋白3在羊水过少孕妇胎盘和胎膜的表达及其意义

Objective To study the expression of aquaporin 1 (AQP1) and aquaporin 3 (AQP3) in fetal membranes and placenta in pregnant women with oligohydramnios and to explore their function in the balance of amniotic fluid. Methods Thirty cases of term pregnancy with oligohydramnios were selected as the experimental group and 30 healthy term pregnant women with normal amniotic fluid volume were served as control. The expressions of mRNA and protein of AQP1 and AQP3 in fetal membranes and placenta were examined by real-time polymerase chain reaction and streptavidi peroxidase immunohistochemiscal staining. Results The expression of AQP1 mRNA in the amnion of the experimental group was 0.31 relative to that of the control group. The expression of AQP1 protein in the amnion of the experimental group was 0.14±0.02, which showed significant decrease when compared with the control (0.25±0.03) (P<0.05), while no significant difference in the chorion and placenta was found between the two groups(P>0.05). The amount of AQP3 mRNA expressions in amnion and chorion in the experimental group were 0.31 and 0.37 relative to those of the control group, respectively, while 7.36 in the placenta. The expression of the AQP3 protein in the amnion and chorion in the experimental group were 0.18±0.05 and 0.18±0.04, respectively, which showed significant decrease when compared with those in the control group (0. 26±0.03 vs 0.29± 0.06, P<0.05). But the expression of AQP3 protein in the placenta of experimental group was significantly higher than that of the control (0.47±0.09 vs 0.28±0.01, P<0.05). Conclusions The alterations of AQP1 and AQP3 expressions in fetal membrane and placenta in oligohydramniotic women are adaptive response to oligohydramnios.     

Abortion in France in 1977

This update of legal abortion in France begins with the history of abortion, the French abortion law, and application since its passage in 1975, and evaluates current acceptance by French physicians. In France, abortion was outlawed in 1923, with the highest numbers of convictions, 5521, in 1946. Increasingly since the late 1960s, the law was neither heeded nor enforced, resulting in a new liberalized law passed in 1975, and put into effect over the next 2 years. Some of the difficulties encountered in implementing legal abortion were: the decision to permit abortion only in approved hospitals, rather than to allow establishment of abortion clinics; resistance of many hospitals or individuals against performing abortions; fixed prices for physicians fees (160 F.) and quotas of 25% of the total surgical and obstetrical patient load; regional variations in availability of abortion; and waiting periods. These problems have led to continuation of black market abortions, fraud in reporting numbers of abortions performed, and have forced some women to travel to other regions of the country or to other countries to obtain safe abortions. Only the 1975 figures are available: there were 45,085 legal abortions, 32,923 in public hospitals and 12,792 in private hospitals. Abortions are easily obtained in large cities and the Southeast, Central and Breton regions but less so in the North and Southwest.     

Differences in female and male perception of information and decision-making in single-embryo transfer in in vitro fertilization in Sweden

Purpose The aim of this study was to evaluate the information and the factors that contribute to the decision to accept and choose single embryo transfer (SET) in females and males. Materials and methods Fifty-four females and males undergoing SET were interviewed separately using a structured questionnaire. Results The women were significantly more satisfied with the information than the men (odds ratio 3.3), but the decision to accept SET was nevertheless more difficult for women (OR 3.1). Only one-third of both female and males were aware of the increased maternal risks with twin pregnancies. There was a tendency that the women who accepted SET had previous children, shorter duration of infertility, and were younger. Cryopreservation of embryos and a good pregnancy chance were important irrespective of gender. Conclusion The female needs more support to choose SET. The male needs better information and further involvement in decision-making. The females were more aware of the fetal risks, but the awareness of the increased maternal risks with twin pregnancies was low. The female need more support to accept and choose single embryo transfer, compared to the male and information should in some areas be directed differently to females and males.
