The Proteome Landscape of Human Placentas for Monochorionic Twins with Selective Intrauterine Growth Restriction.

In perinatal medicine, intrauterine growth restriction (IUGR) is one of the greatest challenges. The etiology of IUGR is multifactorial, but most cases are thought to arise from placental insufficiency. However, identifying the placental cause of IUGR can be difficult due to numerous confounding factors.

Life-threatening postpartum hemorrhage (≥ 5000 mL): a single center experience.

Objectives: To investigate the etiology, interventions and outcome of life-threatening postpartum hemorrhage (PPH) (≥ 5000 mL).

Material And Methods: Retrospective analysis was performed on the clinical data of 42 patients with life-threatening PPH in Peking University Third Hospital from January 2010 to December 2019. According to the causes of PPH, 35 patients were divided into the placenta accrete spectrum (PAS) group and seven patients into the uterine atony group.

Maternal lipid levels in preeclampsia: singleton vs. twin pregnancies.

Objective: To compare the maternal lipid levels in preeclampsia (PE) patients between singleton and twin pregnancies.

Methods: In this retrospective study, pregnant women with PE were divided into singleton group ( = 702) and twin group ( = 198). Serum lipids which include total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured and the TC/HDL-C ratio, TG/HDL-C ratio, and LDL-C/HDL-C ratio were calculated and compared between the two groups.

Computerized analysis of fetal heart rate pattern in the third trimester of low-risk pregnancy by long-range electronic fetal monitoring.

Background: With computerized analysis of fetal heart rate(FHR) data from long-range monitoring, we aimed to comprehensively clarify the characteristics of FHR with increasing gestational age in low-risk pregnant women during the third trimester of pregnancy.

Methods: This was an observational study. 85 fetuses of low-risk pregnant women were included.

Gut microbiota dysbiosis in preeclampsia patients in the second and third trimesters.

Background: Preeclampsia (PE) is a serious complication that affects maternal and perinatal outcomes. However, the mechanisms have not been fully explained. This study was designed to analyze longitudinal gut microbiota alterations in pregnant women with and without PE in the second (T2) and third trimesters (T3).

Differentially expressed circular RNAs in maternal and neonatal umbilical cord plasma from SGA compared with AGA.

Small for gestational age (SGA) has a high risk of mortality and morbidity and is common in obstetrics. To date, no effective prediction and treatment tools are available. Acting as microRNA (miRNA) sponges and disease biomarkers are clear functions of circular RNAs (circRNAs).

Expression of urotensin II is associated with placental autophagy in patients with severe preeclampsia.

The aims of this study are to explore the correlation between the expressions of urotensin II (UII) and autophagic markers (LC3 and P62) in patients with severe preeclampsia (SPE). A total of 64 pregnant subjects were recruited, including 29 healthy pregnancies and 35 preeclamptic patients (7 mild preeclamptic (MPE) patients and 28 SPE patients). UII and autophagic markers expression in placenta specimens was investigated by immunohistochemistry (IHC), RT-qPCR, and western blot.

Effect of Primary Elective Cesarean Delivery on Placenta Accreta: A Case-Control Study.

Background: Cesarean section (CS) is an independent risk factor for placenta accreta. Some researchers think that the timing of primary cesarean delivery is associated with placenta accreta in subsequent pregnancies. The aim of this study was to investigate the risk of placenta accreta following primary CS without labor, also called primary elective CS, in a pregnancy complicated with placenta previa.

Analysis of the Characteristics of Pregnancy and Delivery before and after Implementation of the Two-child Policy.

Background: After the two-child policy is fully implemented, new challenges regarding pregnancy management and the treatment of pregnancy complications will arise. The aim of this study was to analyze the characteristics of pregnancy and delivery before and after the implementation of the two-child policy to make suggestions on the quality assurance of the new era of obstetrics.

Methods: In total, 5895 cases of pregnant women who delivered from April 2016 to March 2017 in Peking University Third Hospital served as the study group and 5103 cases of pregnant women who delivered from January to December 2015 served as the control group.

Statistical Approach to Decreasing the Error Rate of Noninvasive Prenatal Aneuploid Detection caused by Maternal Copy Number Variation.

Analyses of cell-free fetal DNA (cff-DNA) from maternal plasma using massively parallel sequencing enable the noninvasive detection of feto-placental chromosome aneuploidy; this technique has been widely used in clinics worldwide. Noninvasive prenatal tests (NIPT) based on cff-DNA have achieved very high accuracy; however, they suffer from maternal copy-number variations (CNV) that may cause false positives and false negatives. In this study, we developed an algorithm to exclude the effect of maternal CNV and refined the Z-score that is used to determine fetal aneuploidy.

[Clinical analysis of acute hyperlipidemic pancreatitis during pregnancy and postpartum period].

Objective: To describe the characteristics of acute pancreatitis during pregnancy and postpartum.

Methods: From 1994 to 2012, 18 cases of gravida and postpartum women complicated with acute pancreatitis were treated at Peking University Third Hospital and retrospective analysis was performed.

Results: The admission rate due to acute pancreatitis was 41.

[Umbilical cord ligation in the fetocide of complicated monochorionic multiple gestations].

Objective: To evaluate the clinical effect and safety of umbilical cord ligation in the fetocide of complicated monochorionic multiple gestations.

Methods: From January 2009 to December 2012, clinical data of 18 women with complicated monochorionic multiple gestations who experienced intrauterine percutaneous umbilical cord ligation in Peking University Third Hospital were collected. Among the patients, 6 were selective intrauterine growth restriction (1 with type I, 4 with type II, 1 with type III); 4 were acrania or hydropic twins; 4 were acardiac twins, 2 were complicated triplet gestation; 1 was twin-twin transfusion syndrome with right ventricular dysplasia and 1 was monochorionic diamniotic (MCDA) with caesarean section history.

[Research of placental vascular distribution and clinical outcome in monochorionic twins].

Objective: To study the placental vascular distribution of monochorionic (MC) twins with twin-to-twin transfusion syndrome (TTTS) or birth weight discordance.

Methods: Twenty-eight MC placentas were injected in Peking University Third Hospital between Feb. 2010 and Feb.

The WHO near miss criteria are appropriate for admission of critically ill pregnant women to intensive care units in China.

Background: Evaluation of the severity of the pregnant women with suitable admission to the Intensive Care Unit (ICU) is very important for obstetricians. By now there are no criteria for critically ill obstetric patients admitted to the ICU. In this article, we investigated the admission criteria of critically ill patients admitted to the ICU in order to provide a referral basis of reasonable use of the ICU.

Patient with antiphospholipid syndrome accompanied by pre-eclampsia who developed hellp syndrome and eclampsia after abortion.

Antiphospholipid syndrome (APS) refers to a group of clinical symptoms and signs caused by antiphospholipid antibody (aPLA). We reported a rare case of poor outcome of a pregnant woman with APS. The pregnant woman had APS, hemolytic anemia, elevated liver function and low platelet count (HELLP) syndrome, and eclampsia and had a poor outcome from a second pregnancy.

Prenatal diagnosis of anhidrotic ectodermal dysplasia with unconventional loci abnormalities: a case report.

Anhidrotic ectodermal dysplasia (EDA) is a relatively rare congenital hereditary disease. Because of a reduced number of sweat glands, patients are unable to perspire and consequently suffer from hyperthermia and infection. This is a potential cause of death in childhood.
