Objective: To evaluate the safety, efficacy, and long-term effects of catheter ablation with vein of Marshall ethanol infusion for bidirectional mitral isthmus block in patients with persistent atrial fibrillation.

Methods: Two hundred and forty patients from five centers with persistent atrial fibrillation (AF) who underwent radiofrequency ablation from October 2018 to December 2023 were retrospectively analyzed, including 120 patients who underwent traditional pulmonary vein isolation (PVI Only group) and 120 patients who underwent PVI and Marshall vein ablation (Marshall Plus group). The operation time, X-ray exposure, incidence of AF/atrial tachycardia (AT) and complications were compared between the two groups.

DNA-RNA hybrids triggered by double-strand breaks (DSBs) are crucial intermediates during DSB repair, and their timely resolution requires numbers of RNA helicases, including DEAD box 1 (DDX1). However, how these helicases are recruited to DSB-induced hybrids in time remains largely unclear. Here, we revealed that squamous cell carcinoma antigen recognized by T cells 3 (SART3) promotes DDX1 binding to DNA-RNA hybrids at DSBs for optimal homologous recombination (HR) repair.

Accurate analyses of contact problems for rough surfaces are important but complicated. Some assumptions, namely that all asperities can be approximated by a hemisphere with the same radius and assuming a Gaussian distribution of the asperity heights, are convenient but may lead to less accurate results. The purpose of this work is to investigate these assumptions and analyze the conditions under which they are valid.

Nuclear factor erythroid 2-related factor 2 (NRF2) is a redox-sensitive transcriptional factor that enables cells to resist oxidant responses, ferroptosis and inflammation. Here, we set out to probe the effects of NRF2 on cardiomyocyte injury under acute myocardial infarction (AMI) condition and its potential mechanism. Human cardiomyocytes were exposed to hypoxia/reoxygenation (H/R) to induce cell injury.

Article Synopsis
  • The study investigates the relationship between lipid levels, glucose levels, and inflammation (cytokines) in patients with various types of coronary artery disease (CAD).
  • Data were collected from 2,147 patients diagnosed with different CAD stages, analyzing factors like IL-6, INF-γ, and Hb1Ac levels across groups such as stable angina, unstable angina, NSTEMI, and STEMI.
  • Results show that acute myocardial infarction patients have significantly higher IL-6 levels and varying lipid and glucose profiles compared to other CAD groups, suggesting that inflammation and metabolic factors may play critical roles in coronary heart disease progression.

Article Synopsis
  • - The study investigates how silica nanoparticles (SiNPs) affect lung health by examining the interactions between different cell types in the lungs and how they contribute to lung injuries.
  • - Using a model where rats were exposed to varying doses of SiNPs, researchers found that these particles caused significant lung damage characterized by inflammation, cell death, and changes in cell functions, particularly in macrophages, epithelial cells, and fibroblasts.
  • - Findings highlighted the role of heat shock proteins, especially Hspd1, in the lung damage caused by SiNPs, linking it to oxidative stress and disruptions in protein balance, thus shedding light on the molecular mechanisms behind SiNP-induced pulmonary toxicity.

Article Synopsis
  • VGLL3 is identified as a key player in the DNA damage response (DDR), which helps cells repair damaged DNA.
  • Decreasing VGLL3 levels leads to reduced repair efficiency, making cells more sensitive to chemotherapy while delaying tumor growth.
  • The study also reveals that VGLL3 stabilizes certain proteins involved in DNA repair by preventing their degradation, highlighting a unique function separate from its role in regulating gene transcription.

Background: Acupuncture is a promising non-pharmaceutical complementary therapy in treating prolonged Disorders of consciousness (pDOC), but solid evidence to support its effectiveness and safety is still lacking. Thus, the purpose of this study is to investigate the efficacy and safety of acupuncture-assisted therapy for pDOC patients.

Methods: A single-center, prospective, randomized, conventional-controlled, assessor-and-statistician-blinded trial has been designed and is being conducted at West China Hospital of Sichuan University.

Article Synopsis
  • Low-density lipoprotein cholesterol (LDL-C) is an important risk factor for cardiovascular disease, but its effects on the microvasculature, particularly in the retina, are not well-studied.
  • A study involving 243 elderly patients categorized them based on LDL-C levels to analyze retinal vessel density and other factors using a non-invasive imaging technology called optical coherence tomography angiography (OCTA).
  • Findings revealed that patients with LDL-C levels above 2.6 mmol/L had significantly lower retinal vessel density compared to those with lower levels, highlighting a negative correlation between LDL-C and retinal microvasculature health.

Aims: Coronary heart disease (CHD) patients with changed serum soluble receptor for advanced glycation end products (sRAGE) will experience microalbuminuria and even kidney dysfunction. However, the role of sRAGE for microalbuminuria in CHD is still not established. This study aimed to evaluate the association between sRAGE and early kidney dysfunction in CHD patients.

Background: Inflammatory responses play a central role in myocardial ischemia/reperfusion (I/R) injury. Previous studies have demonstrated that the receptor for advanced glycation end-products (RAGE) is involved in the pro-inflammatory process of myocardial I/R injury by binding to diverse ligands. Thus, the inhibitory effects of soluble receptor for advanced glycation end-products (sRAGE), a decoy receptor for RAGE, on myocardial I/R injury may be associated with a reduced inflammatory state.

The toxicity of silica nanoparticles (SiNPs) to lung is known. We previously demonstrated that exposure to SiNPs promoted pulmonary impairments, but the precise pathogenesis remains elucidated. Ferroptosis has now been identified as a unique form of oxidative cell death, but whether it participated in SiNPs-induced lung injury remains unclear.

Background: In the context of increasing exposure to silica nanoparticles (SiNPs) and ensuing respiratory health risks, emerging evidence has suggested that SiNPs can cause a series of pathological lung injuries, including fibrotic lesions. However, the underlying mediators in the lung fibrogenesis caused by SiNPs have not yet been elucidated.

Results: The in vivo investigation verified that long-term inhalation exposure to SiNPs induced fibroblast activation and collagen deposition in the rat lungs.

RAD18, an important ubiquitin E3 ligase, plays a dual role in translesion DNA synthesis (TLS) and homologous recombination (HR) repair. However, whether and how the regulatory mechanism of O-linked N-acetylglucosamine (O-GlcNAc) modification governing RAD18 and its function during these processes remains unknown. Here, we report that human RAD18, can undergo O-GlcNAcylation at Ser130/Ser164/Thr468, which is important for optimal RAD18 accumulation at DNA damage sites.

Background: Adult neurogenesis occurs in the subventricular zone (SVZ) and the subgranular zone of the dentate gyrus in the hippocampus. The neuronal stem cells in these two neurogenic niches respond differently to various physiological and pathological stimuli. Recently, we have found that the decrement of carboxypeptidase E (CPE) with aging impairs the maturation of brain-derived neurotrophic factor (BDNF) and neurogenesis in the SVZ.

Environmental, Social and Governance (ESG) is closely related to the "dual carbon" objective and the concept of sustainable development. The impact of ESG performance on audit efficiency, especially on audit delays, is still an issue to be studied in depth. Drawing on stakeholder theory, sustainable development theory, shared value concept and corporate social responsibility theory, this study adopts regression analysis and structural equation modeling (SEM) to investigate the impact of ESG on audit efficiency based on the data of A-share listed companies in the period of 2015-2022, with a focus on audit delay.
