ABSTRACT
The aim of the study was to investigate the etiology and pregnancy outcomes in mothers with polyhydramnios through prenatal diagnosis and pregnancy outcome analysis of pregnant women with polyhydramnios. One hundred and thirty women were enrolled. Fifty pregnant women with polyhydramnios were categorized as the case group, and 80 pregnant women with normal amniotic fluid were categorized as the control group. The causes of polyhydramnios and the pregnancy outcomes were analyzed. Two cases had chromosomal abnormalities, seven had severe α-thalassemia, 15 had fetal anomalies, four had maternal-fetal diseases and 22 had unexplained idiopathic polyhydramnios. Significantly, higher occurrences of cesarean section, preterm birth, fetal anomaly, fetal distress, fetal macrosomia and female fetuses occurred in patients with polyhydramnios than in patients without polyhydramnios. Polyhydramnios is associated with a higher occurrence of adverse perinatal outcomes. Intensive monitoring of the maternal-fetal condition and prenatal diagnosis is important in patients with polyhydramnios.

OBJECTIVE: To investigate the mRNA and protein expression of FK506-binding protein 52 (FKBP52) in the chorionic villi of patients with recurrent spontaneous abortion (RSA) and normal women during early pregnancy. METHODS: Fresh chorionic villus tissues were collected from 60 subjects. A total of 30 patients with a history of RSA were enrolled into the RSA group and 30 normal pregnant women were enrolled into the control group. The FKBP52 mRNA expression levels in chorionic villi of the RSA patients and healthy controls were measured via semiquantitative RT-PCR. The protein distribution and expression levels of FKBP52 in chorionic villi were analyzed through immunohistochemistry (IHC). The correlation between FKBP52 expression and RSA was analyzed. RESULTS: We demonstrated that FKBP52 mRNA is expressed in chorionic villi samples of normal pregnancy and RSA. RSA patients exhibited significantly lower FKBP52 gene expression levels compared with those in normal pregnancies (p < 0.05). FKBP52 immunoreactivity in chorionic villi was mainly observed in trophoblast cell cytoplasm. The FKBP52 protein expression levels in the chorionic villi of RSA patients was significantly lower than in normal women during pregnancy (p < 0.05). CONCLUSIONS: FKBP52 protein levels were decreased in the chorionic villi of RSA patients, which indicate that the decrease in FKBP52 may be associated with RSA. The low FKBP52 mRNA expression level, which is consistent with the IHC result, may affect embryonic development and even lead to abortion. FKBP52 may be involved in the pathogenesis of RSA and new therapies that increase the FKBP52 expression may help treat RSA.
