Clinical Accuracy of the G.LAB MD41A0 Upper Arm Blood Pressure Monitor in Pregnancy and Pre-Eclampsia Using the AAMI/ESH/ISO as Reference Standard.

Objective: Validation of blood pressure (BP) monitors in pregnant women are needed to ensure the accurate measurement of BP in pregnancy. Therefore the study aimed to evaluate the measurement accuracy of the G.LAB MD41A0 oscillometric automatic upper-arm blood pressure monitor in pregnancy and pre-eclampsia women according to the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018).

METTL14-mediated lncRNA XIST silencing alleviates GDM progression by facilitating trophoblast cell proliferation and migration via the miR-497-5p/FOXO1 axis.

Gestational diabetes mellitus (GDM), a prevalent complication during the gestation period, has been linked to impaired proliferation and migration of trophoblasts causing placental maldevelopment. We previously found that lncRNA X-inactive specific transcript (XIST) played an essential role in GDM progression. Here, we investigated the precise biological functions as well as the upstream and downstream regulatory mechanisms of XIST in GDM.

The clinical effect of aspirin combined with low-molecular-weight heparin in the treatment of severe preeclampsia and the combination's effect on pregnancy outcomes.

Objective: To explore the clinical effects of aspirin combined with low-molecular-weight heparin (LMWH) in the treatment of patients with severe preeclampsia and the combination's influence on pregnancy outcomes.

Methods: From October 2018 to June 2020, 104 patients with severe preeclampsia who underwent treatment in our hospital were recruited as the study cohort and divided into two groups according to different treatment scheme each patient underwent. In the research group (RG), the 54 patients were administered aspirin combined with LMWH, and the other 50 patients in the control group (CG) were administered routine treatment.

LncRNA XIST serves as a diagnostic biomarker in gestational diabetes mellitus and its regulatory effect on trophoblast cell via miR-497-5p/FOXO1 axis.

Background: Gestational diabetes mellitus (GDM) is increasingly common in pregnancy. This study's purpose was to identify the expression of XIST and manifest the potential mechanism of XIST in GDM.

Methods: Ninety-three patients with GDM and 93 normal pregnant women were included in this investigation.

MicroRNA-652-3p promotes the proliferation and invasion of the trophoblast HTR-8/SVneo cell line by targeting homeobox A9 to modulate the expression of ephrin receptor B4.

MicroRNAs (miRNAs) are emerging as novel modulators in the pathogenesis of preeclampsia (PE). Multiple miRNAs have been shown to regulate the proliferation and invasion of trophoblast cells, which play a critical role in successful pregnancies. miR-652-3p has been identified as a novel disease-associated miRNA that is dysregulated in various pathological processes.

MicroRNA-454 contributes to sustaining the proliferation and invasion of trophoblast cells through inhibiting Nodal/ALK7 signaling in pre-eclampsia.

MicroRNAs (miRNAs) are emerging as important regulators in the pathogenesis of pre-eclampsia (PE). Recent evidence has reported that miR-454 plays an important role in regulating cell proliferation and invasion. The decreased proliferation and invasion of trophoblast cells contribute to the pathogenesis of PE.

The study of GPX3 methylation in patients with Kashin-Beck Disease and its mechanism in chondrocyte apoptosis.

Objective: Selenium deficiency is a risk factor for Kashin-Beck Disease (KBD), an endemic osteoarthropathy. Although promoter hypermethylation of glutathione peroxidase 3 (GPX3) (a selenoprotein) has been identified in several cancers, little is known about promoter methylation and expression of GPX3 and their relation to selenium in KBD. The present study was thus conducted to investigate this research question.

Progesterone maintains the status of granulosa cells and slows follicle development partly through PGRMC1.

Progesterone receptor membrane component 1 (PGRMC1) mediates antimitotic and antiapoptotic actions of progesterone in granulosa cells, which indicates that PGRMC1 may play a key role in maintaining the status of granulosa cells. The current study investigated the effects of progesterone on intracellular signaling involved in differentiation, follicle development, inflammatory responses, and antioxidation, and determined the role of PGRMC1 in these processes. Our results demonstrated that progesterone slowed follicle development and inhibited p-ERK1/2, p-p38, caspase-3, p-NF-κB, and p-IκB-α signals involved in differentiation, steroidogenesis, and inflammatory responses in granulosa cells.

Progesterone production requires activation of caspase-3 in preovulatory granulosa cells in a serum starvation model.

Granulosa cells proliferate, differentiate, and undergo apoptosis throughout follicular development. Previous studies have demonstrated that stimulation of progesterone production is accompanied by caspase-3 activation. Moreover, we previously reported that arsenic enhanced caspase-3 activity coupled with progesterone production.

[Peripheral blood mononuclear cell of neonates infected with hepatitis B virus].

Objective: To study the mechanism and significance of peripheral blood mononuclear cell (PBMC) of neonates infected with hepatitis B virus (HBV).

Methods: Eighty-four HBsAg-positive and HBeAg-negative mothers and their newborns were recruited in this study. Sixteen hepatitis B virus markers (HBVM)-negative mothers and their neonates were served as control.

[The role of peripheral blood mononuclear cells (PBMC) of HBV-infected mothers in the intrauterine infection of their fetuses].

Objective: To study the role of the HBV-infected mothers' PBMC in intrauterine transmission of HBV to their fetuses.

Methods: Thirty pregnant women with serum HBV DNA negative and PBMC HBV DNA positive and their newborns were used as the study group. Ten pregnant women with serum HBV negative and their infants served as the control group.

[Clinical significance of detecting neonatal peripheral blood mononuclear cells infected by HBV].

Objective: To understand the HBV infection rate of peripheral blood mononuclear cells (PBMCs) from fetuses of HBsAg positive mothers, associated risk factors and to explore the clinical significance of detecting HBV infected PBMCs.

Methods: Sixty eight pregnant women who were delivered at the First Hospital of Xi'an Jiaotong University, China from August 1995 to February 1997, and their newborns were studied. They were divided into two groups according to their status of HBV serological markers.
