Objectives: To evaluate the early clinical efficacy and safety of trans-catheter aortic valve replacement (TAVR) for patients with severe pure native aortic regurgitation (PNAR) who are not suitable for conventional surgical aortic valve replace-ment.

Methods: A retrospective analysis was conducted on 48 patients with PNAR who underwent TAVR at the Department of Cardiac Surgery, the First Affiliated Hospital of Sun Yat-sen University between March 2019 and February 2025. These included 25 cases with transfemoral approach (TF-TAVR group) and 23 cases with transapical approach (TA-TAVR group).

The SARS-CoV-2 papain-like protease (PLpro) is a multifunctional viral protein that facilitates viral assembly and disrupts host immune responses by removing interferon-stimulated gene 15 (ISG15) modifications from target proteins. However, the mechanisms by which PLpro-mediated immune evasion leads to inflammatory responses are not well understood. In this study, we demonstrate for the first time that PLpro induces inflammation in colonic epithelial cells and colonic inflammation in a mouse model, acting through the ISG15 signaling pathway.

Background: The defect of the distal index finger may cause tissue necrosis, osteomyelitis, even dysfunction, disability in hand, and psychological problems. This study aimed to present our experiences using a modified second toe nail-skin flap to repair and reconstruct the distal index finger defect.

Methods: From February 2018 to April 2022,48 patients with the distal index finger defects received the modified second toe nail-skin flap to reconstruct the defect.

Background: The triglyceride-glucose (TyG) index, proven a reliable and simple surrogate of insulin resistance, has shown potential associations with cardiovascular outcomes and renal diseases. This research delved into the utility of the TyG index in predicting the risk of acute kidney injury (AKI) in patients with coronary artery disease (CAD), an area not extensively covered in existing literature.

Methods: A cohort of patients with CAD was recruited from the Medical Information Mart for Intensive Care-IV database, and categorized into quartiles based on their TyG index.

Recent studies have suggested that sVEGFR3 is involved in cardiac diseases by regulating lymphangiogenesis; however, results are inconsistent. The aim of this study was to investigate the function and mechanism of sVEGFR3 in myocardial ischemia/reperfusion injury (MI/RI). sVEGFR3 effects were evaluated in vivo in mice subjected to MI/RI, and in vitro using HL-1 cells exposed to oxygen-glucose deprivation/reperfusion.

Neutralizing antibody titres have been shown to correlate with immune protection against COVID-19 and can be used to estimate vaccine effectiveness. Numerous studies have explored the relationship between neutralizing antibodies and protection. However, there remains a lack of quantitative data directly assessing the minimum effective protective neutralizing antibody titre in .

Background: This study aimed to summarize the pathogenic spectrum of infective endocarditis (IE) and analyze the risk factors for poor prognosis in surgical patients in a tertiary hospital in China.

Methods: We retrospectively included patients diagnosed with IE between January 2013 and January 2022. The pathogenic spectrum was summarized; the risk factors for early postoperative mortality and embolic events were analyzed using multivariate logistic regression.

Article Synopsis
  • Vein grafts are critical for treating coronary artery disease, but neointimal hyperplasia (NIH) poses a significant challenge to their long-term success, with current identification and intervention methods being insufficient.
  • Researchers conducted a study using rats to observe the NIH development process after vein grafting while examining gene expression and specific markers related to NIH through various analytical methods.
  • The results showed that repair cells from outside the graft contribute significantly to NIH, with the protein Fhl1 playing a protective role against inflammation and cell proliferation, offering potential targets for improved treatments.

Research on virus/receptor interactions has uncovered various mechanisms of antibody-mediated neutralization against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, understanding of neutralization by antibodies targeting the silent face, which recognize epitopes on glycan shields, remains limited, and their potential protective efficacy in vivo is not well understood. This study describes a silent face neutralizing antibody, 3711, which targets a non-supersite on the N-terminal domain (NTD) of the spike protein.

This study utilizes data from A-share listed companies between 2011 and 2020 to empirically investigate the impact and mechanism of public welfare donations on the internal income gap of enterprises. The research findings indicate that public welfare donations significantly increase the per capita salary of management, while their impact on the per capita salary of ordinary employees is not significant, thus leading to an expansion of the internal income gap within enterprises. The results from mechanism testing reveal that the income tax benefits resulting from charitable donations and the rise in corporate operating income have contributed to an increase in excess rent shared by enterprises and employees.

Article Synopsis
  • The study analyzed 199 patients on ECMO support, revealing a high mortality rate of 76.38% and identified key risk factors for mortality.
  • Continuous renal replacement therapy (CRRT) and age were found to be independent risk factors, with age having the strongest predictive ability for death at a cutoff of 48.5 years.
  • Additionally, patients on combined CRRT and ECMO without congenital heart disease or a previous surgical history faced increased mortality risks.

Understanding the genetic basis of neuro-related proteins is essential for dissecting the molecular basis of human behavioural traits and the disease aetiology of neuropsychiatric disorders. Here the SCALLOP Consortium conducted a genome-wide association meta-analysis of over 12,000 individuals for 184 neuro-related proteins in human plasma. The analysis identified 125 cis-regulatory protein quantitative trait loci (cis-pQTL) and 164 trans-pQTL.

The electrocatalytic carbon dioxide reduction reaction (ECRR) is promising in converting environmentally harmful CO into useful chemicals, but the large-scale application of this technology is seriously limited by its low efficiency and selectivity. Cu-based electrocatalysts displayed attractive ability in converting CO to multiple products, and the product selectivity can be manipulated through various approaches. Among them, exposing specific crystal facets through crystal facet engineering has been proven to be highly effective in obtaining specific products and has attracted numerous researchers.

Rapid removal of toxic substances is crucial to restore the normal functions of our body and ensure survival. Due to their high substrate specificity and catalytic efficiency, enzymes are unique candidates to deplete toxic compounds. While enzymes display several limitations including low stability and high immunogenicity, these can be overcome by entrapping them in a diverse range of carriers.

Omicron, as the emerging variant with enhanced vaccine tolerance, has sharply disrupted most therapeutic antibodies. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the subgenus Sarbecovirus, members of which share high sequence similarity. Herein, we report one sarbecovirus antibody, 5817, which has broad-spectrum neutralization capacity against SARS-CoV-2 variants of concern (VOCs) and SARS-CoV, as well as related bat and pangolin viruses.

Objective: In patients receiving extracorporeal membrane oxygenation (ECMO), continuous renal replacement therapy (CRRT) is increasingly being used for renal replacement and fluid management. However, critically ill surgical patients receiving combined ECMO and CRRT tend to have a high mortality rate, and there are limited studies on this population. Therefore, we aimed to investigate the risk factors for mortality in surgical patients receiving combined ECMO and CRRT.

Coronaviruses (CoVs) have brought serious threats to humans, particularly severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2), which continually evolves into multiple variants. These variants, especially Omicron, reportedly escape therapeutic antibodies and vaccines, indicating an urgent need for new antivirals with pan-SARS-CoV-2 inhibitory activity. We previously reported that a peptide fusion inhibitor, P3, targeting heptad repeated-1 (HR1) of SARS-CoV-2 spike (S) protein, could inhibit viral infections.
