Mechanical ventilation patients admitted to the critical care department of the First Affiliated Hospital of Guangxi Medical University from July to November 2023 were enrolled. According to the random number table generated by Excel, the patients were divided into negative pressure group, positive pressure group 1 and positive pressure group 2, with 45 cases in each group. On the basis of routine nursing, the negative pressure group used the negative pressure extubation technique to remove the tracheal catheter. In the positive pressure group, the pressure support (PS) and positive end-expiratory pressure (PEEP) of the positive pressure group 1 were 7 cmH&lt;sub&gt;2&lt;/sub&gt;O (1 cmH&lt;sub&gt;2&lt;/sub&gt;O≈0.098 kPa) and 5 cmH&lt;sub&gt;2&lt;/sub&gt;O, and the PS and PEEP of the positive pressure group 2 were 15 cmH&lt;sub&gt;2&lt;/sub&gt;O and 10 cmH&lt;sub&gt;2&lt;/sub&gt;O. The main outcome measures were extubation related complications, including tachypnea, severe cough, sore throat, upper airway obstruction spasm, extubation failure, hypoxemia, and hypercapnia.

The datasets GSE57065, GSE9960, and GSE28750 were integrated into an analysis dataset by the surrogate variable analysis (SVA) package and analyzed this analysis dataset by using the \"limma\" package to obtain differentially expressed gene (DEG), then the intersection set of DEG, FRG, and IRG were considered as ferroptosis and immune-related DEG (FImDEG). Gene ontology (GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed using \"ClusterProfiler\" to understand the biological function of FImDEG. The key genes were screened by protein-protein interaction (PPI) network, least absolute shrinkage and selection operator (LASSO) regression algorithms, and support vector machine (SVM) analyses, and Logistic regression model was built based on above key genes. Receiver operator characteristics curve (ROC curve) was plotted to evaluate the diagnostic efficacy of the key genes alone or combinative. The degree of infiltration of 22 immune cells was assessed using the \"CIBERSORT\" package, and the correlation between the expressions of key genes and infiltration degree of immune cells was analyzed.

A total of 4 537 DEG were obtained, including 2 066 up-regulated genes and 2 471 down-regulated genes. 2 519 IRG and 855 FRG were obtained from the relevant database. Using the intersection of DEG, IRG and FRG, 34 FImDEG were obtained, including 20 up-regulated genes and 14 down-regulated genes. GO functional annotation showed that the biological functions of 34 FImDEG were mainly inhibition of transferase activity, regulation of DNA-binding transcription factor activity and cell response to stimulation. In terms of molecular function, it was mainly related to RNA polymerase II-specific DNA-binding transcription factor binding and various protein ligase binding. Changes in cell composition occurred mainly in promyelocytic leukemia protein and chromatin silencing complexes. Enrichment analysis of KEGG pathway showed that the major pathways involved in 34 FImDEG included cell aging, expression of programmed death-ligand 1 (PD-L1) and programmed death-1 (PD-1) checkpoint pathways in cancer, interleukin-17 (IL-17) signaling pathway, lipid and atherosclerosis, and NOD-like re","PeriodicalId":24079,"journal":{"name":"Zhonghua wei zhong bing ji jiu yi xue","volume":"36 10","pages":"1025-1032"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142717211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the registration study data of CABG patients at Fuwai Hospital, Chinese Academy of Medical Sciences, the clinical data of adult patients who underwent CABG from January 2013 to December 2022 were analyzed. Preoperative use of RASi (PreRASi) was defined as receiving RASi treatment within 48 hours before surgery. Postoperative acute kidney injury (AKI) was defined using the diagnostic criteria of Kidney Disease: Improving Global Outcomes (KDIGO). Demographic characteristics, past medical history, comorbidities, preoperative medication, preoperative laboratory test results, specific information on surgical procedures, and postoperative treatment related data were extracted. The primary endpoint was the incidence of postoperative AKI. Secondary endpoints included in-hospital all-cause mortality and all-cause mortality within the longest follow-up period. According to whether RASi was used before surgery, the patients were divided into PreRASi group and No-PreRASi group. The baseline data of the two groups were balanced by propensity score matching (PSM).

The ACOP animal model was reproduced using carbon monoxide (CO) inhalation in a hyperbaric oxygen chamber, while the normal control group was allowed to breathe fresh air freely. The rats in the SFN intervention group received intraperitoneal injection of SFN at a dose of 20 mg/kg once daily starting 2 hours after CO poisoning and continuing until euthanasia. The normal control group and the ACOP model group received equivalent volume of saline injection. Three rats from each group were sacrificed 1 day after intervention to observe the changes in the ultrastructure of neuronal mitochondria in brain tissues under transmission electron microscopy. Six rats from each group were evaluated for cognitive function using neurobehavioral test 7 days after intervention. Brain tissues of 6 rats in each group were collected 1, 3, and 7 days after intervention, and the expressions of phosphorylated-adenosine monophosphate-activated protein kinase (p-AMPK), mitofusin 2 (MFN2), and dynamin-related protein 1 (DRP1) were detected using immunohistochemistry staining and Western blotting. Linear regression analysis was performed to assess the correlations between the expression levels of above proteins.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In the normal control group, the rats did not exhibit any abnormalities in cognitive function or the ultrastructure of neuronal mitochondria in brain tissues. ACOP induced cognitive impairment and ultrastructural injury to neuronal mitochondria in rats. However, SFN significantly improved cognitive function in poisoned rats and mitigated the extent of neuronal mitochondrial damage. Over poisoning time, the expression levels of p-AMPK and MFN2 in the brain tissues of ACOP rats were gradually decreased, while the expression level of DRP1 was gradually increased. Compared with the normal control group, the ACOP model group showed significant differences in the expressions of p-AMPK, MFN2, and DRP1. After SFN intervention, the expression levels of above proteins were significantly reversed. Compared with the ACOP model group, the SFN intervention group exhibited a marked increase in the expressions of p-AMPK and MFN2 [p-AMPK positive expression (A value): 0.226±0.003 vs. 0.177±0.033, p-AMPK protein (p-AMPK/GAPDH): 1.41±0.05 vs. 0.89±0.05, MFN2 positive expression (A value): 0.241±0.004 vs. 0.165±0.007, MFN2 protein (MFN2/GAPDH): 1.33±0.04 vs. 0.79±0.03, all P &lt; 0.05], along with a significant decrease in DRP1 expression [DRP1 positive expression (A value): 0.103±0.002 vs. 0.214±0.011, DRP1 protein (DRP1/GAPDH): 1.00±0.03 vs. 1.50±0.03, both P &lt; 0.05].

At present, the pathogenesis of new-onset atrial fibrillation in sepsis has not been fully elucidated. Studies have shown that both sepsis and atrial fibrillation are closely related to NOD-like receptor protein 3 (NLRP3). NLRP3 inflammasome can not only induce the activation of caspase-1 and the subsequent release of cellular pro-inflammatory factors, but also participate in the occurrence and development of sepsis and promote the occurrence and development of atrial fibrillation. It is concluded that the NLRP3 inflammasome may play an important role in the occurrence and development of new-onset atrial fibrillation in sepsis. This paper summarized the current research progress on the structure and function of the NLRP3 inflammasome, its role in sepsis, its mechanism in promoting atrial fibrillation, the relationship between the NLRP3 inflammasome and new-onset atrial fibrillation in sepsis, the feasibility of studying new-onset atrial fibrillation in sepsis, and potential therapeutic targets for new-onset atrial fibrillation in sepsis.
