Differences in general condition and the incidence of maternal and neonatal complications were compared between the two groups. AA group were further divided into adverse outcome subgroup (n=33) and non-adverse outcome subgroup (n=52), and relevant factors were also analyzed. Statistical analysis was performed using t-test, Chi-square test and logistic regression. \u0000 \u0000 \u0000Results \u0000No maternal deaths occurred in all 85 cases of AA group, 81 of them gave live birth [one neonate died and the others survived with a mean gestational age of 36+5 weeks (30+2-40+5 weeks)], and 45 developed maternal or fetal adverse outcomes.

The fetus with increased nuchal translucency (3.2 mm) detected by ultrasound scan at 13+4 gestational weeks received NIPS and the result was negative in chromosomes 21, 18 and 13. A routine ultrasound examination at 22 weeks of gestation revealed multiple anomalies and a second NIPS was offered, which showed a negative result again. The pregnancy was terminated at 22+3 weeks. Multiple fetal and placental biopsies were collected for chromosome analysis using copy number variation sequencing based on high-throughput sequencing and fluorescence in situ hybridization. The fetal karyotype was shown to be 47,XY,+18 in fetal tissues (skin and liver) and umbilical cord, while no chromosomal abnormalities was detected at or near the center of the fetal and maternal surface of the placenta. Results of the chromosomal analysis along the edges of the fetal and maternal surfaces of the placenta were Chr18:47,XY,+18[60]/46,XY[40] and Chr18:47,XY,+18[35]/46,XY[65], respectively. We inferred that placental mosaicism was the cause of the false negative NIPS result. Therefore, genetic counseling before and after NIPS is necessary. Follow-up ultrasound is important for NIPS-negative patients.

Chorionic villus and decidua tissues were collected from another 10 women who aborted in early pregnancy. Two in vitro trophoblastic hypoxia cultures were established by subjecting human chorionic trophoblast cells (HTR8/SVneo) to either hypoxia intervention in incubator (HII) or simulated ischemic buffer (SIB). Wip1 expressions at the transcriptional and protein levels were determined by real-time quantitative polymerase chain reaction and Western blotting, respectively. The localization of Wip1 in placental tissues and HTR8/SVneo cells was determined by immunohistochemistry and immunofluorescence. Cell apoptosis was assessed by flow cytometry after viral infection and hypoxia. And the changes of pathway-related molecules including p53, phospho-p53 (p-p53), mouse double minute 2 homolog (Mdm2) and cleaved caspase3 (cl-cas3) were measured by Western blotting. The impact of Wip1 on Mdm2-p53 interaction was examined by co-immunoprecipitation. NVP-CGM097, an Mdm2-p53 specific inhibitor, was administered in PE cell models to verify the regulation of Wip1 on trophoblastic apoptosis through Mdm2-p53 pathway.
