Development and validation of a risk prediction model for postpartum urinary incontinence in primiparas with singleton pregnancies: a multicenter clinical investigation.

Background: Postpartum urinary incontinence (UI) is a serious condition that significantly affects the quality of life. Several studies have demonstrated that it is associated with pelvic floor dysfunction. This study aimed to develop and validate a UI risk prediction model to identify primiparas with singleton pregnancies at high risk.

Pyrotinib induces cell death in HER2-positive breast cancer via triggering HSP90-dependent HER2 degradation and ROS/HSF-1-dependent oxidative DNA damage.

HER2-positive breast cancer (HER2+ BC) is distinguished by its poor prognosis, propensity for early onset, and high risk of recurrence and metastasis. Consequently, anti-HER2-targeted therapy has emerged as a principal strategy in the treatment of this form of breast cancer. Pyrotinib, a novel irreversible pan-HER2 tyrosine kinase inhibitor, has brought fresh hope to patients with advanced HER2+ breast cancer.

Umbilical Cord-Derived Mesenchymal Stem Cells Improve Ornidazole-Induced Asthenozoospermia in Rats via Activation of the AKT/mTOR Pathway.

Mesenchymal stem cells (MSCs) have been highly confirmed for their critical role in the treatment of different diseases. This study focuses on the mechanism of umbilical cord-derived MSCs (UC-MSCs) in the treatment of ornidazole (ORN)-induced asthenozoospermia (AS) in rats via the AKT/mTOR pathway. An animal model of AS was established in ORN-induced rats, followed by treatment of UC-MSCs and rapamycin (autophagy activator) or MK-2206 (AKT inhibitor).

Effects of multilevel postpartum family planning intervention on the reduction of unintended pregnancy and induced abortion rates within 12 months of delivery: A cluster randomized controlled study in China.

Objectives: This study aimed to evaluate the effects of a multilevel promoting postpartum family planning (PPFP) intervention on the reduction of unintended pregnancies and induced abortions in China.

Study Design: We performed a cluster randomized intervention study to assess the effects of a multilevel PPFP intervention on the rates of unintended pregnancy and induced abortion within 12 months postpartum. Thirty-six hospitals were included and randomly allocated to two groups at a 1:1 ratio, enrolling 180 pregnant women per hospital starting in January 2019.

Inflammatory bowel disease and risk of ophthalmic inflammation-related diseases: a two-sample Mendelian randomization study.

Aim: To investigate the causal effect of inflammatory bowel disease (IBD) on ocular inflammation using Mendelian randomization (MR) analysis.

Methods: Genetic instruments associated with inflammatory bowel disease (IBD), ulcerative colitis (UC), and Crohn's disease (CD) were derived from the largest genome-wide association studies (GWAS) published to date. The FinnGen research project was utilized to identify genetic risk variants associated with conjunctivitis, keratitis, iridocyclitis, chorioretinitis, episcleritis, and optic neuritis.

USP11 promotes lipogenesis and tumorigenesis by regulating SREBF1 stability in hepatocellular carcinoma.

Background: The relationship between hepatocellular carcinoma (HCC) metastasis and cancer metabolism reprogramming is becoming increasingly evident. Ubiquitin-specific protease 11 (USP11), a member of the deubiquitinating enzyme family, has been linked to various cancer-related processes. While USP11 is known to promote HCC metastasis and proliferation, the precise mechanisms, especially those related to cancer metabolism, remain unclear.

Chrysotoxine regulates ferroptosis and the PI3K/AKT/mTOR pathway to prevent cervical cancer.

Ethnopharmacological Relevance: Dendrobium (commonly known as Shihu in China), a traditional Chinese medicinal herb recognized in the Pharmacopoeia of China (2020 edition), boasts a rich history of medicinal application. Extensive research has been conducted on its Chinese medicinal prescription due to its demonstrated anti-tumour effects in clinical settings. Dendrobium is comprised of a diverse range of chemical compounds, notably the Bibenzyls, Erianin, and Gigantol, which have exhibited significant inhibitory and therapeutic effects on cervical cancer, thereby suggesting potential therapeutic value.

Mental Health in Early Pregnancy and Spontaneous Abortion Risk: A Prospective Cohort Study.

Objective: This study aims to explore the relationship between maternal mental health during early pregnancy and the risk of spontaneous abortion (SA), especially in the context of the Coronavirus disease 2019 pandemic.

Methods: We conducted a prospective cohort study involving 4088 pregnant women at a maternal-child health hospital in China from January to December 2022. During the first trimester, we assessed depression, anxiety, and stress levels using the Depression, Anxiety, and Stress Scale (DASS-21).

The E3 ubiquitin ligase RNF6 facilitates the progression of cervical cancer by inhibiting the Hippo/Yap pathway.

Purpose: Cervical cancer (CC), a significant global health threat, necessitates comprehensive understanding for improved therapeutic interventions. Many research indicates that dysregulation of the Hippo-YAP1 pathway leads to uncontrolled proliferation and invasion of tumor cells, promoting the progression of various cancers. This article aims to elucidate the role of RNF6 in CC and its regulation of the Hippo-YAP1 signaling pathway.

Clinical features and risk factors of Klebsiella pneumoniae infection in premature infants: a retrospective cohort study.

Background: With the continuous advancement of modern medical technology, the survival rate of premature infants has significantly increased. Klebsiella pneumoniae (K. pneumoniae) is one of the most common pathogens causing neonatal infections, particularly posing a serious risk to premature infants.

Analysis of single-cell RNA sequencing in human oocytes with diminished ovarian reserve uncovers mitochondrial dysregulation and translation deficiency.

Background: Diminished ovarian reserve (DOR) is clinically characterized by a decrease in the number of available ovarian follicles and a decline in the quality of oocytes, accompanied by hormonal changes. Low quality of DOR oocyte leads to impaired embryo development, an increased risk of aneuploid pregnancies and miscarriages. However, the specific pathogenic mechanism remains unclear, posing a significant challenge for assisted reproductive technology.

Isoliquiritigenin induced hepatotoxicity and endoplasmic reticulum stress in zebrafish embryos.

Isoliquiritigenin (ISL), a naturally occurring flavonoid derived from licorice root, exhibits antioxidant, anticancer, anti-inflammatory, and anti-allergic properties, and is frequently detected in both environmental and human samples. Previous studies from our lab have demonstrated that ISL exposure can lead to developmental deformities and aberrant immune responses. However, the molecular mechanisms underlying ISL toxicity in zebrafish embryos remain incompletely elucidated.

Effect of ultrasound-guided individualized positive end-expiratory pressure on the severity of postoperative atelectasis in elderly patients: a randomized controlled study.

Postoperative pulmonary complications (PPCs) are common in patients undergoing general anesthesia, with atelectasis being a key contributor that increases postoperative mortality and prolongs hospitalization. Our research hypothesis is that ultrasound-guided individualized PEEP titration can reduce postoperative atelectasis. This single-center randomized controlled trial recruited elderly patients for laparoscopic surgery.
