Visualization of Confined Electrons at Grain Boundaries in a Monolayer Charge-Density-Wave Metal.

1D grain boundaries in transition metal dichalcogenides (TMDs) are ideal for investigating the collective electron behavior in confined systems. However, clear identification of atomic structures at the grain boundaries, as well as precise characterization of the electronic ground states, have largely been elusive. Here, direct evidence for the confined electronic states and the charge density modulations at mirror twin boundaries (MTBs) of monolayer NbSe, a representative charge-density-wave (CDW) metal, is provided.

Neonatal hyperinsulinism with an mutation: A case report.

Background: Neonatal hyperinsulinism can result from perinatal stress, genetic disorders, or syndromes, which can lead to persistent or intractable hypoglycemia in newborns. Mutations in the gene result in abnormal functioning of potassium channel proteins in pancreatic β-cells, leading to an overproduction of insulin and congenital hyperinsulinemia.

Case Summary: We report a case of a high-birth-weight infant with postnatal hypoglycemia and hyperinsulinemia, whose mother had pregestational diabetes mellitus with poor glycemic control and whose sister had a similar history at birth.

Endometrial squamous cell carcinoma originating from the cervix: A case report.

Background: Cervical squamous cell carcinoma (SCC) is the most common type of cervical carcinoma and is generally derived from a precancerous stage called cervical high-grade squamous intraepithelial lesion (HSIL). Usually, the cancer metastasizes through lymphatic or hematogenous dissemination, but rarely spreads upward into the uterus. Here, we report a case of cervical HSIL extending into the endometrium and finally progressing to SCC in the uterine cavity.

IGFBP7 enhances trophoblast invasion via IGF-1R/c-Jun signaling in unexplained recurrent spontaneous abortion.

In Brief: Insufficient trophoblast invasion at the maternal-fetal interface contributes to abortion-prone pregnancy. Our study shows that decreased levels of IGFBP7 in unexplained recurrent spontaneous abortion (URSA) trophoblast cells inhibit MMP2 and Slug expression as well as trophoblast invasion, suggesting that IGFBP7 should be considered a potential therapeutic protein target in URSA.

Abstract: Insufficient trophoblast invasion at the maternal-fetal interface contributes to abortion-prone pregnancy.

Myomatous erythrocytosis syndrome: A case report.

Background: Uterine myoma is the most common benign tumor among women and is often accompanied by anemia. Here, we report the case of a patient with a very large leiomyoma but with a hemoglobin level as high as 197 g/L. After undergoing hysterectomy, all her hematological parameters returned to normal.

Effect of a carbohydrate-rich beverage on rate of cesarean delivery in primigravidae with epidural labor analgesia: a multicenter randomized trial.

Background: Labor represents a period of significant physical activity. Inefficient energy supply may delay labor process and even lead to cesarean delivery. Herein we investigated whether ingestion of a carbohydrate-rich beverage could reduce cesarean delivery in laboring women with epidural analgesia.

Four-year-old anti-N-methyl-D-aspartate receptor encephalitis patient with ovarian teratoma: A case report.

Background: A population-based comparative study in United States shows that the prevalence and incidence of autoimmune encephalitis are comparable to those of infectious encephalitis and its detection is increasing over time. Some patients are complicated with ovarian teratoma. The younger the patient is, the less likely a tumor will be present.

Neuraxial labor analgesia is associated with a reduced risk of postpartum depression: A multicenter prospective cohort study with propensity score matching.

Background: Depression is a common and serious complication in new mothers. We investigated the hypothesis that neuraxial labor analgesia is associated with a decreased risk of postpartum depression.

Methods: In this multicenter prospective cohort study with propensity score matching, 599 nulliparous women with single term cephalic pregnancy who planned vaginal delivery were enrolled and self-selected neuraxial analgesia or not.

Successful pregnancy after protective hemodialysis for chronic kidney disease: A case report.

Background: Chronic kidney disease (CKD) affects almost 3% of females of child-bearing age, who have a high risk of adverse maternal and fetal outcomes. Additionally, high renal burden as a result of pregnancy may lead to deterioration of renal function. An increasing number of women with CKD stages 3 to 5 have a strong desire to conceive, and both obstetricians and nephrologists are faced with enormous challenges in terms of their treatment and management.

Phosphoproteomics reveals the apoptotic regulation of aspirin in the placenta of preeclampsia-like mice.

Preeclampsia (PE) is a severe gestational complication, and dysfunctional placenta plays an essential role in PE pathogenesis. Although low-dose aspirin is currently the most promising prophylactic drug for PE prevention, the exact mechanism of aspirin remains unclear. A previous study reported that treatment with low-dose aspirin could ameliorate PE-like symptoms in lipopolysaccharide (LPS)-induced PE-like mouse model.

The association of the glucokinase rs4607517 polymorphism with gestational diabetes mellitus and its interaction with sweets consumption in Chinese women.

Objective: To identify the association of the glucokinase gene (GCK) rs4607517 polymorphism with gestational diabetes mellitus (GDM) and determine whether sweets consumption could interact with the polymorphism on GDM in Chinese women.

Design: We conducted a case-control study at a hospital including 1015 participants (562 GDM cases and 453 controls). We collected the data of pre-pregnancy BMI, sweets consumption and performed genotyping of the GCK rs4607517 polymorphism.

Evaluation of the gestational diabetes mellitus diagnostic criteria recommended by the international association of diabetes and pregnancy study group for long-term maternal postpartum outcomes in mainland China.

The gestational diabetes mellitus (GDM) diagnostic criteria recommended by the International Association of Diabetes and Pregnancy Study Group (IADPSG) were established based on the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study and have been the most commonly used criteria for determining GDM worldwide. Although individuals from mainland China were not included in the HAPO study, the IADPSG criteria have been used in China since 2011. However, the appropriateness of the criteria for evaluating maternal postpartum outcomes in mainland China are unknown.

Increasing insulin resistance predicts adverse pregnancy outcomes in women with gestational diabetes mellitus.

Background: This study aimed to investigate the association between maternal insulin resistance (IR) in the late second trimester and pregnancy outcomes, as well as to identify risk factors of IR among women with gestational diabetes mellitus (GDM).

Methods: A retrospective study was conducted among 2647 women diagnosed with GDM. IR was evaluated using the homeostasis model assessment method for IR (HOMA-IR) in the late second trimester (between 24 and 28 weeks), and the lipid profiles were measured at the same time.

Factors associated with human papillomavirus infection - findings from a cervical cancer screening program for female employees in Beijing.

Background: In 2018, the Beijing Federation of Trade Unions organized a cervical cancer screening program for female employees for the first time. This study aimed to investigate the screening results of this program and determine the factors associated with human papillomavirus (HPV) infection.

Methods: A total of 8297 female employees participating in the screening program between January 1, 2018, and December 31, 2018, were enrolled in this study.

Association of adiposity with thyroid nodules: a cross-sectional study of a healthy population in Beijing, China.

Background: The relationship between thyroid nodules (TNs) and adiposity is controversial. This paper describes a cross-sectional investigation performed to determine the existence of any such relationship. To assess adiposity, body mass index (BMI) and visceral fat area (VFA) were utilized.

Thyroid function of twin-pregnant women in early pregnancy.

Background: Serum human chorionic gonadotrophin (hCG) is higher in twin than that in singleton pregnancies. As hCG stimulates the thyroid to produce more free thyroxine (FT4), which may lead to decreased thyroid-stimulating hormone (TSH) levels, the reference ranges of thyroid-related indicators may differ between singleton and twin pregnancies in the first trimester. This study aimed to establish reference ranges for thyroid-related indicators in early twin pregnancies and to compare them with singleton pregnancies.

Value of fasting plasma glucose to screen gestational diabetes mellitus before the 24th gestational week in women with different pre-pregnancy body mass index.

Background: Gestational diabetes mellitus (GDM) is usually diagnosed between 24th and 28th gestational week using the 75-g oral glucose tolerance test (OGTT). It is difficult to predict GDM before 24th gestational week because fast plasma glucose (FPG) decreases as the gestational age increases. It is controversial that if FPG ≥5.

[Testicular histology does not affect the clinical outcomes of ICSI in men with non-obstructive azoospermia].

Objective: To investigate whether testicular histology influences the clinical outcomes of intracytoplasmic sperm injection (ICSI) in men with non-obstructive azoospermia (NOA).

Methods: We retrospectively analyzed the clinical data about 73 cases of NOA undergoing ICSI, including 105 ICSI cycles and 79 embryo transfer cycles. The infertility of the patients was attributed to male factors only or both male and female tube factors and the females' age was ≤38 years.
