This study aimed to investigate the effect of Art on intestinal injury after CA and cardiopulmonary resuscitation (CPR) in swine. Methods: Twenty-two swine were randomly divided into three groups: sham (n = 6), CA/CPR (n = 8), and CA/CPR + Art (n = 8). The CA/CPR swine model was established by inducing 9 min of untreated ventricular fibrillation (VF) followed by 6 min of CPR. Five minutes after resuscitation, 4.8 mg/kg of Art was intravenously administered for 2 h in the CA/CPR + Art group. Intestinal fatty acid-binding protein and diamine oxidase concentrations were compared among the three groups before CA and at 1, 2, 4, and 24 h after resuscitation. At 24 h after resuscitation, intestinal zonula occluden-1 (ZO-1), occludin, apoptosis, caspase-3/gasdermin E (GSDME)-mediated pyroptosis proteins concentrations, and proinflammatory cytokine concentrations were examined to evaluate intestinal injury. Results: During CPR, spontaneous circulation was achieved in seven and six swine in the CA/CPR and CA/CPR + Art groups, respectively. Serum intestinal fatty acid-binding protein and diamine oxidase concentrations were significantly higher and intestinal tissue ZO-1 and occludin concentrations were significantly lower in the CA/CPR and CA/CPR + Art groups than in the sham group. However, Art treatment resulted in markedly improved levels of intestinal injury biomarkers compared with those in the CA/CPR group. Additionally, intestinal apoptosis and concentrations of caspase-3/GSDME-mediated pyroptosis proteins and proinflammatory cytokines were significantly higher in the CA/CPR and CA/CPR + Art groups than in the sham group. However, these variables were significantly lower in the CA/CPR + Art group than in the CA/CPR group.

Methods: We developed a novel method using the D 4 -Chip to assess sepsis T-cell migration function.

Methods: Patients presenting to a level I trauma center as trauma activations had samples collected within 12 h of time of injury, alongside healthy volunteers (HV). CitH3 was measured by enzyme-linked immunosorbent assay, and TG data were measured using a TG analyzer, comparing results between patients developing symptomatic VTE versus those who did not, within 90 days of injury.

Despite extensive research, the specific metabolic pathways contributing to sepsis remain unclear. This study aims to elucidate the causal relationships between CSF metabolites and sepsis risk using Mendelian randomization (MR), offering insights that could lead to novel therapeutic strategies. Methods: We conducted a two-sample MR analysis using genetic variants as instrumental variables (IVs) to investigate 338 CSF metabolites identified through a genome-wide association study. Data on sepsis-related outcomes were extracted from the genome-wide association study catalog encompassing 486,484 individuals of European descent. IVs were rigorously selected based on stringent genetic association and linkage disequilibrium criteria. Statistical analyses, including inverse variance weighting (IVW) and weighted median methods, were performed using the \"TwoSampleMR\" package in R software, supplemented by comprehensive sensitivity analyses to ensure the robustness of our findings. Results: Our analysis identified 19 CSF metabolites causally associated with sepsis risk. Notably, metabolites such as 1-palmitoyl-2-stearoyl-gpc (16:0/18:0) and 2-hydroxyglutarate showed significant negative correlations with sepsis risk. The reverse MR analysis further revealed that sepsis could negatively impact certain CSF metabolite levels, particularly ribonate, suggesting a bidirectional relationship. These relationships were substantiated by rigorous statistical testing and sensitivity analyses confirming the absence of horizontal pleiotropy and the stability of our results across various MR methods. Conclusions: This study demonstrates significant causal associations between specific CSF metabolites and the risk of developing sepsis, highlighting the potential for these metabolites to serve as biomarkers or therapeutic targets.

The following study investigates neuron-specific enolase (NSE) as a potential biomarker for lung injury after blunt TT. Methods: This is a retrospective analysis of prospectively collected data in a level 1 trauma center from 2014 to 2020. Serum levels of NSE and ILs (IL-6, IL-10) in injured patients (n = 41) with isolated TT (Abbreviated Injury Scale score of the thorax ≥3) compared with isolated TBI (Abbreviated Injury Scale score of the head ≥3) were assessed from days 0 to 5 after trauma.

Methods: Human AC16 cardiomyocyte cells were cultured under anaerobic condition to induce an in vitro model of myocardial ischemia. Cell apoptosis was assessed by Annexin V-fluorescein isothiocyanate staining and caspase-3 and caspase-9 activity assays. Cell proliferation was analyzed by 5-ethynyl-2'-deoxyuridine incorporation assay. Inflammation was evaluated by enzyme-linked immunosorbent assays. Circ_0068655, miR-370-3p, and BCL-2-like 11 (BCL2L11) expression were detected by real-time quantitative polymerase chain reaction or western blotting. The target interactions among circ_0068655, miR-370-3p, and BCL2L11 were predicted using bioinformatics tools and validated using dual-luciferase reporter assays and RNA immunoprecipitation assays. Results: Hypoxia treatment led to upregulated expression of circ_0068655 and BCL2L11, and downregulated expression of miR-370-3p in AC16 cells.
