Knocking down macrophages Caspase-6 through HMGB1 coordinates macrophage trophoblast crosstalk to suppress ferroptosis and alleviate preeclampsia.

Objective: Caspase-6 is an important regulatory factor in innate immunity, inflammasome activation, and host defense, but its role in preeclampsia (PE) is unknown. This study aims to investigate the mechanism of Caspase-6 in the interaction between PE rats and macrophage-trophoblast cells, in order to provide a new theoretical basis for the treatment of PE.

Methods: Co-cultures of THP-1 cells and HTR8/SVneo cells were employed to investigate the HMGB1 signaling in macrophages (transfection with si-Caspase-6) and HTR8/SVneo cells.

PPARγ alleviates preeclampsia development by regulating lipid metabolism and ferroptosis.

The study aims to explore the effect of PPARγ signaling on ferroptosis and preeclampsia (PE) development. Serum and placental tissue are collected from healthy subjects and PE patients. The PPARγ and Nrf2 decreases in the PE.

Insulin-like growth factor 1 ameliorates pre-eclampsia by inhibiting zinc finger E-box binding homeobox 1 by up-regulation of microRNA-183.

As a common hypertensive complication of pregnancy, preeclampsia (PE) remains one of the leading causes of maternal and fetal with high morbidity and mortality worldwide. Much research has identified the vital functions of insulin-like growth factor 1 (IGF-1) in PE treatment. However, the combined roles and molecular mechanism of IGF-1 and microRNAs (miRNAs) underlying PE remain unclear.

Monitoring hypertensive disorders in pregnancy to prevent preeclampsia in pregnant women of advanced maternal age: Trial mimicking with retrospective data.

This study investigated the implication of monitoring hypertensive disorders in pregnancy (HDP) to prevent preeclampsia (PE) in pregnant women of advanced maternal age. Between January 2016 and April 2021, 262 consecutive pregnant women aged ≥40 years were recruited. Extensive monitoring of hypertensive disorders in pregnancy, including blood hypercoagulability screening and subsequent interventions, was performed in 129 pregnant women in our university hospital.

miR-2115-3p inhibits ferroptosis by downregulating the expression of glutamic-oxaloacetic transaminase in preeclampsia.

Introduction: Recently, ferroptosis has been reported to be closely related to preeclampsia (PE). However, the mechanisms associated with ferroptosis in PE have been poorly studied.

Methods: A PE rat model was established via reduced uterine perfusion pressure (RUPP) surgery.

Diagnosis, management, and neurodevelopmental outcomes of fetal hydrocephalus: an observational prospective study.

The etiology of fetal hydrocephalus is complex, and the outcome of fetal neurodevelopment after birth is also different. The purpose of this study is to conduct anti-infection of hydrocephalus fetuses with non-specific infection, and observe their neurodevelopment after birth, so as to provide clinical basis for further guidance and management of fetal hydrocephalus. Eighteen single pregnant women with fetal hydrocephalus confirmed by intrapartum ultrasonography in the Second Xiangya Hospital between July 1, 2019, and December 1, 2020, were included.

Long-term outcomes of pregnant women with pulmonary hypertension diagnosed by echocardiography: a retrospective cohort study in a single center from China.

Recent studies suggest that pregnancy may not be absolutely contraindicated in women with moderate pulmonary hypertension. We aimed to evaluate the long-term outcomes of pregnant women with pulmonary hypertension diagnosed by echocardiography in our clinical department. Pregnant women with pulmonary hypertension, diagnosed by a pulmonary systolic arterial pressure > 30 mmHg via echocardiography, who were admitted in our department for termination of pregnancy or delivery between 2004 and 2016 were included in this retrospective cohort study.

Elevated MicroRNA 183 Impairs Trophoblast Migration and Invasiveness by Downregulating FOXP1 Expression and Elevating GNG7 Expression during Preeclampsia.

Preeclampsia (PE) is a hypertensive disorder of uncertain etiology that is the leading cause of maternal and fetal morbidity or mortality. The dysregulation of microRNAs (miRNAs) has been highlighted as a potential factor involved in the development of PE. Therefore, our study investigated a novel miRNA, miRNA 183 (miR-183), and its underlying association with PE.

GNG7 silencing promotes the proliferation and differentiation of placental cytotrophoblasts in preeclampsia rats through activation of the mTOR signaling pathway.

Preeclampsia (PE) is a pathological condition that manifests during pregnancy as the occurrence of an abnormal urine protein level and increased blood pressure due to inadequate cytotrophoblast invasion. To elucidate the mechanism underlying PE, the present study primarily focused on the regulatory effects and mechanism of the G protein γ 7 (GNG7) on placental cytotrophoblasts in a rat PE model. Initially, the PE model was established with 45 specific pathogen‑free Sprague‑Dawley rats (30 females and 15 males).

Concordance of tomographic ultrasound and multiplanar ultrasound in detecting levator ani muscle injury in patients with pelvic organ prolapse.

Aim: To compare the evaluations of evaluate levator ani muscle injury (LAMI) by tomographic ultrasound imaging (TUI) and multiplanar (MP) ultrasound in patients with pelvic organ prolapse (POP).

Method: This retrospective analysis studied women who underwent International Continence Society POP quantification examination between October 2015 and June 2016. LAMI was assessed by both TUI and MP ultrasounds.

Mechanism of endogenous digitalis-like factor‑induced vascular endothelial cell damage in patients with severe preeclampsia.

Although endogenous digitalis‑like factor (EDLF) is associated with the development of various physical disorders, the role in preeclampsia remains unclear. This study investigated the effects of EDLF on vascular endothelial cell damage in patients with preeclampsia and the potential mechanisms. From July 2014 to July 2015, 120 singleton pregnancy cases underwent a prenatal examination, inpatient delivery and had normal blood pressure were included in the study, either as patients with severe preeclampsia or the control patients.

Tegafur Substitution for 5-Fu in Combination with Actinomycin D to Treat Gestational Trophoblastic Neoplasm.

Although 5-fluorouracil (5-Fu) combination chemotherapy provides a satisfactory therapeutic response in patients with gestational trophoblastic neoplasms (GTNs), it has severe side effects. The current study analyzed the therapeutic effects and side effects of tegafur plus actinomycin D (Act-D) vs. 5-Fu plus Act-D for the treatment of GTNs based on controlled historical records.

Corticotropin-releasing hormone activates connexin 43 via activator protein-1 transcription factor in human myometrial smooth muscle cells.

Corticotropin-releasing hormone (CRH) and connexin 43 (Cx43) play crucial roles in uterine contraction and the onset of labor. The aim of the present study was to investigate the regulatory effects of CRH on Cx43 expression in human myometrial smooth muscle cells (SMCs) and, potentially, its activation of the c-Fos/activator protein (AP)-1 signaling pathway. Human myometrial SMCs collected from nonpregnant women were treated with different concentrations of CRH.
