Case Report: A 35-year-old primigravida with a previous surgical history of laparoscopic myomectomy underwent elective cesarean section at 39 weeks and 2 days of gestation. During surgery, there were severe pelvic adhesions and engorged vessels on the anterior wall.

An advanced understanding of the heterogeneous clinical features of "non-criteria" obstetric antiphospholipid syndrome: Two case reports and a literature review.

Antiphospholipid syndrome (APS) is an acquired autoimmune disorder characterized by recurrent venous and/or arterial thrombosis and/or pregnancy complications, in the presence of elevated antiphospholipid (aPL) antibodies. APS in pregnant women is referred to as "obstetrical" APS (OAPS). The diagnosis of definite OAPS requires the presence of one or more typical clinical criteria and persistent aPL antibodies at least 12 weeks apart.

Complete cervical inversion and nearly inappropriate stitching with cesarean section during the second stage of labor: a case report.

Cesarean section is a common obstetric operation and an important method for saving the lives of mothers and their neonates in dangerous situations. Nevertheless, cesarean section has a higher risk and might have more complications compared with natural delivery. A reasonable choice of delivery method is important for maternal and neonatal health.

Apgar score and neonatal mortality in China: an observational study from a national surveillance system.

Background: To examine the association between the Apgar score and neonatal mortality over gestational age in China and to explore whether this association changed when Apgar scores were combined at 1 and 5 min.

Methods: Data for all singleton live births collected from 438 hospitals between 2012 and 2016 were used in this study. Poisson regression with a robust variance estimator adjusted for a complete set of confounders was used to describe the strength of the association between the Apgar score and neonatal mortality.

Objective: To investigate the expression of miRNA-148b-3p and its target gene in the placenta between normal pregnant women and pregnant women with intrahepatic cholestasis of pregnancy (ICP) and to explore the possible mechanism of glucose metabolism of offspring with maternal cholestasis.

Methods: There were 30 cases of normal pregnant women and 30 cases of pregnant women with ICP recruited in the study, all of whom underwent cesarean delivery from Mar. 2017 to Jan.

'Standardized patients' in teaching the communication skill of history-taking to four-year foreign medical undergraduates in the department of obstetrics and gynaecology.

Background: Many foreign students have difficulty taking histories from Chinese patients, especially in clinical context of the Department of Obstetrics and Gynaecology. The efficacy of using standardized patients to prepare foreign students for communicating with Chinese patients and taking their histories was evaluated in this study.

Methods: Ninety-four four-year foreign students were assigned to one of three clinical sub-departments (gynaecology, obstetrics, and reproductive endocrinology) to practice history-taking; after practicing in one sub-department, the students were then crossed over to a different department.

Prevalence of postterm births and associated maternal risk factors in China: data from over 6 million births at health facilities between 2012 and 2016.

Postterm births are associated with an increased risk of adverse perinatal outcomes, but few studies have investigated the epidemiological characteristics of postterm births. We aimed to estimate the prevalence of postterm births and examine the potential association between maternal sociodemographic and obstetric characteristics and postterm births. Data were collected from China's National Maternal Near Miss Surveillance System, 2012-2016.

A single-center experience with 12 consecutive cases of pregnancy among patients with membranous ventricular septal aneurysm.

Background: Membranous ventricular septal aneurysm (MVSA) is a rare cardiac anomaly that can occur as an isolated entity or being associated with other cardiac malformations. Complications of MVSA include thromboembolism, arrhythmia, rupture, bacterial endocarditis, right ventricular outflow tract obstruction, and atrioventricular valve diseases.The success rate of pregnancy and delivery in patients with MVSA has not been reported in the literature.

Objectives: To evaluate the clinical application value of internal iliac artery balloon occlusion in pernicious placenta previa.

Methods: We retrospectively reviewed the medical records of the patients of pernicious placenta previa in a single center from Jan, 2010 to Jan, 2015. The patients were divided into two groups, internal iliac artery balloon occlusion group and the control group without endovascular intervention.

Pregnancy outcome in women with Eisenmenger's syndrome: a case series from west China.

Background: Eisenmenger's syndrome (ES) consists of pulmonary hypertension with a reversed or bidirectional shunt at the atrioventricular, or aortopulmonary level. The cardiovascular changes that occur during the pregnancy contribute to the high maternal morbidity and mortality in patients with ES. This study is to assess maternal and fetal outcomes in patients with ES.

[Perinatal Management for Monochorionic Twin Reversed Arterial Perfusion Sequence].

Objective: To evaluate the perinatal managementof monochorionic twin pregnancies complicated by twin reversed arterial perfusion (TRAP) sequence.

Methods: A retrospectively study was performed on the management and perinatal outcome of monochorionic multiple pregnanciescomplicated by TRAP sequence at West China Second University Hospital from May 2010 to May 2014.

Results: Thirteen cases of TRAP sequence were identified during the study period, included 4 monochorionicmonoamniotic (MCMA) twins, 7 monochorionic diamniotic(MCDA) twins,1 monochorionic-triamniotic (MCTA) triplet pregnancy and 1 MCDA triplet pregnancy.

Intravenous Iron Sucrose versus Oral Iron in the Treatment of Pregnancy with Iron Deficiency Anaemia: A Systematic Review.

Background: Intravenous iron sucrose and oral iron therapy are the main therapies for iron deficiency anaemia (IDA), but there is still a debate regarding their efficacy and especially as to which one is the best choice during pregnancy.

Methods: A meta-analysis of randomised controlled trials comparing patients treated with intravenous iron sucrose (intravenous group) with those treated with oral iron (oral group) for IDA during pregnancy was performed. The primary outcomes of interest were mean maternal haemoglobin and serum ferritin levels at the end of treatment.

Perinatal outcomes of pregnancies complicated by preterm premature rupture of the membranes before 34 weeks of gestation in a tertiary center in China: A retrospective review.

Preterm premature rupture of the membranes (PPROM) remains the leading cause of preterm deliveries and neonatal mortality and morbidity. The current cohort study sought to retrospectively examine perinatal outcomes in cases of PPROM < 34 weeks' gestation that were managed conservatively from 2010 to 2012 and to identify risk factors for short-term neonatal outcomes. Subjects were 510 pregnancies consisting of 114 twin and 396 singleton pregnancies.

The role of levonorgestrel-releasing intrauterine system for endometrial protection in women with breast cancer taking tamoxifen.

Purpose Of Investigation: To review the evidence concerning the efficacy of levonorgestrel-releasing intrauterine system (LNG-IUS) in preventing endometrial pathology in women treated with tamoxifen.

Materials And Methods: Randomized controlled trials (RCTs) of women with breast cancer on tamoxifen that compared endometrial surveillance or placebo alone vs. the LNG-IUS were reviewed.

Silent rupture of an unscarred uterus at third-trimester abortion correlated with an unrecognized perforation.

Silent uterine rupture in an unscarred uterus during pregnancy is rare. We present a case of silent uterine rupture in an unscarred uterus at third-trimester abortion by use of mifepristone and misoprostol in a patient who had a history of intrauterine procedures. The absence of clinical symptoms suggests that this uterine rupture resulted from an unrecognized perforation in a previous intrauterine manipulation.
