Objective To investigate pregnancy complications,cesarean delivery and abnormal fetal presentation in women with uterine anomalies.Methods Fifty women diagnosed with uterine malformation and sixty women with normal uterus were retrospectively analyzed .Results The group comprised women with uterine malformation had significantly higher stillbirth or fetal death (P <0.05) and lower rates of the full-term delivery(P <0.05) than that of the control group.The subgroup comprised women with uterine anomalies had significantly higher rates of cesare -an section(P <0.05) and abnormal fetal position(P <0.05) than the control group.The birth weight and length of infant in observation group were significantly lower than those in control group (P <0.05).The rate of placenta abnormalities in uterine anomalies was significantly higher than that in control group (P <0.05).The incidences of premature rupture of membrane,cord entanglement,oligohydramnios,postpartum hemorrhage and neonatal asphyxia in observation group were no significant difference than those in control group .The rate of premature rupture of membrane(PROM) in uterus unicornis was significantly higher than that in other types (P <0.05).Conclusion Compared with women with normal uterus ,the incidences of abnormal fetal position ,the placenta abnormalities,pre-mature delivery,and stillbirth or fetal death in women with congenital uterine anomalies are high .Uterine anomalies are associated with a decrease in the birth weight and length .We should pay more attention to finding the uterine malformation and treatment before pregnancy .Antenatal care should be reinforced in pregnancy women with uterine anomalies.

Objective To evaluate diagnosis of cord entanglem ent and fetus safety by B ultra-sonic and nemodromometer. Methods 86 pregnant women were diagnosed as cord entanglement in late pregnancy by B ultrasonic examination and Doppler blood flow analysis of the S/D ratio from ma r to May, 1999. The pregnancy outcomes were followed up. Cord entanglement,es -pecially the high blood circulating resistance, suggested that there was h igh risk of fetal distress. The obstetrician would manage the delivery stage pro perly according to the results of Doppler examination.Results 7 2 women were proved cord entanglement after delivery wity coincident rate of 83. 7%. Five women were delivered by cesarean section and forceps among 11 cases of abno rmal S/D ratio, and the rate of operative delivery in group with abnormalS/D rat io was significantly higher than that of the group with normal S/D ratio (P ＜0.05). Conclusions The combined examination can improve the rate of diagnosis of cord entanglement and abnormal S/D ratio, forecast the feta l distress, reduce birth rate of infant with lower Apgar score and reduce the ces arean section rate due to social factor.

Objective To understand the expressions of transforming growth factor ?1(TGF-?1) and its receptors(T?R) in villi and decidua during early pregnancy and their effects on early embryo development, and explore the mechanism of spontaneous abortion. Methods By immunohistochemical technique, expressions of TGF-?1 and its receptors were determined in villi and decidua from 10 cases of spontaneous abortion women after in vitro fertilization and embryo transfer (IVF-ET group), 20 cases of spontaneous abortion women (spontaneous abortion group), and 20 cases of normal early pregnancy women (control group). Results TGF-?1 and its receptors had high expressions in decidua cells, villus glands and interstitial cytoplasm in all three groups. The average light density of the expressions of TGF-?1 in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.167 and 0.199, 0.198 and 0.201, 0.277 and 0.274, respectively. The intensity of T?R-Ⅰ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.144 and 0.150, 0.202 and 0.201, 0.238 and 0.281, respectively. And the expressions of T?R-Ⅱ in the villi and decidua of IVF-ET, spontaneous abortion and control groups were 0.199 and 0.145, 0.153 and 0.156, 0.300 and 0.301, respectively. The differences between the control group and both abortion groups were all significant (P
