Introduction: Premature ovarian insufficiency (POI) is a condition characterized by ovarian dysfunction occurring before the age of 40, and its etiology is multifactorial, including genetic, immunological, infectious, environmental, and iatrogenic factors, with over half of the cases remaining unexplained. Whether the microbial communities and metabolites in follicular fluid, which is the direct microenvironment for oocyte survival, are related to POI has not been reported.
Methods: In this study, Follicular fluid samples of 26 patients with POI and 27 controls with a normal ovarian reserve were collected and analyzed using 16S rDNA sequencing and untargeted metabolomics.
Pyroptosis is a key mode of programmed cell death during the early stages following acute myocardial infarction (AMI), driving immune-inflammatory responses. Cardiac resident macrophages (CRMs) are the primary mediators of cardiac immunity, and they serve a dual role through their shaping of both myocardial injury and post-AMI myocardial repair. To appropriately regulate AMI-associated inflammation, HM4oRL is herein designed, an innovative bifunctional therapeutic nanoplatform capable of inhibiting cardiomyocyte pyroptosis while reprogramming inflammatory signaling.

This prompts an intriguing investigation into the nuanced differences between these two treatment methods.
Background: This study aimed to compare the efficacy of spectacle lenses with highly aspherical lenslets (HAL) versus orthokeratology (Ortho-k) in controlling axial length elongation.
Microgravity-induced cardiac remodeling and dysfunction present significant challenges to long-term spaceflight, highlighting the urgent need to elucidate the underlying molecular mechanisms and develop precise countermeasures. Previous studies have outlined the important role of miRNAs in cardiovascular disease progression, with miR-199a-3p playing a crucial role in myocardial injury repair and the maintenance of cardiac function. However, the specific role and expression pattern of miR-199a-3p in microgravity-induced cardiac remodeling remain unclear.

However, the necessity of this combination treatment strategy in SRDs remains uncertain.
Objective: This retrospective study aimed to evaluate the effectiveness of TPE alone versus TPE combined with IVIG/IVMP in treating severe SRDs.
Objective: To assess the visual quality in patients with primary angle-closure glaucoma (PACG) complicated by cataracts after cataract phacoemulsification with intraocular lens (IOL) implantation and goniosynechialysis, and to explore the relationship between pupil size and visual quality.
Methods: A retrospective, non-randomized study was conducted, including 65 PACG patients (75 eyes) who underwent cataract surgery with IOL implantation and goniosynechialysis from July 2021 to June 2023, as well as a control group of cataract-only patients. Visual quality was evaluated using objective and subjective methods at least 3 months postoperatively.
: Clonorchiasis is a foodborne parasitic disease that can lead to severe biliary fibrosis and cholangiocarcinoma. While praziquantel (PZQ) is available for clonorchiasis treatment, it cannot revert the histopathological damage incurred through parasite-induced fibrosis. Curcumin (CUR) is an emerging experimental drug possessing anti-inflammatory and fibrosis-alleviating effects, thus signifying its potential as an anthelmintic drug.

As the main target cells of DENV, macrophages are responsible for the innate immune response against the virus.
Methods: In this study, we investigated the role of pyroptosis in the pathogenic mechanism of dengue fever by examining the level of pyroptosis in DENV-1-infected macrophages and further screened differentially expressed microRNAs by high-throughput sequencing to predict microRNAs that could affect the pyroptosis of the macrophage.
Sepsis is a life-threatening organ dysfunction resulting from a dysregulated host response to infections that is initiated by the body's innate immune system. Nearly a decade ago, we discovered that bacterial lipopolysaccharide (LPS) and serum amyloid A (SAA) upregulated Connexin 43 (Cx43) and Pannexin 1 (Panx1) hemichannels in macrophages. When overexpressed, these hemichannels contribute to sepsis pathogenesis by promoting ATP efflux, which intensifies the double-stranded RNA-activated protein kinase R (PKR)-dependent inflammasome activation, pyroptosis, and the release of pathogenic damage-associated molecular pattern (DAMP) molecules, such as HMGB1.

Background: Minimally invasive surgeries are increasingly central to modern medicine, particularly in liver transplantation. These techniques, which offer reduced trauma, precise operations, minimal bleeding, and swift recovery, are, however, unevenly adopted across China. Only a limited number of centers routinely perform minimally invasive donor hepatectomies, indicating a significant imbalance in the development and application of these advanced procedures.
