Elderly patients (aged ≥ 60 years) admitted to the ICU of Tianjin Medical University General Hospital from November 2023 to June 2024 were enrolled. Clinical records were collected, and conduct muscle mass and strength measurements, as well as upper arm circumference and calf circumference were measured. Appendicular skeletal muscle index (ASMI) of less than 7.0 kg/m<sup>2</sup> for males and less than 5.7 kg/m<sup>2</sup> for females was defined as reduced muscle mass, grip strength of less than 28 kg for males and less than 18 kg for females was defined as decreased muscle strength, patients meeting both low muscle mass and low muscle strength criteria were diagnosed with sarcopenia. According to the diagnostic criteria for sarcopenia, patients were divided into sarcopenia group and non-sarcopenia group. Multivariate Logistic regression analysis was applied to identify risk factors for sarcopenia in the elderly and to develop a predictive model for the occurrence of sarcopenia.

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.

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.

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). Logistic regression model and Cox proportional hazards model were used to assess the correlation between PreRASi and postoperative AKI and clinical outcomes, and analyze the subgroups of hypertension and heart failure with preserved ejection fraction (HFpEF) in the cohort.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 33 884 patients who underwent CABG were included, with a mean follow-up duration of (3.0±2.4) years and the longest follow-up duration up to 8.5 years. There were 9 128 cases (26.94%) in the PreRASi group and 24 756 cases (73.06%) in the No-PreRASi group. The incidence of postoperative AKI in the PreRASi group was 47.61% (4 346 cases), compared to 52.37% (12 964 cases) in the No-PreRASi group. Two groups were matched with 5 094 patients each. Compared to the No-PreRASi group, both before and after PSM, PreRASi was associated with a reduction of risk of postoperative AKI [before PSM: odds ratio (OR) = 0.834, 95% confidence interval (95%CI) was 0.793-0.877, P &lt; 0.001; after PSM: OR = 0.875, 95%CI was 0.808-0.948, P = 0.001]. Subgroup analysis of hypertensive and HFpEF patients showed that PreRASi was associated with a decreased risk of postoperative AKI before and after PSM. The in-hospital mortality for the PreRASi and No-PreRASi groups were 0.61% (56 cases) and 0.49% (121 cases), respectively. Analysis of the overall cohort and subgroups with hypertension and HFpEF showed no correlation between PreRASi and in-hospital mortality or longest follow-up mortality.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;The perioperative use of RASi can reduce the risk of postoperati","PeriodicalId":24079,"journal":{"name":"Zhonghua wei zhong bing ji jiu yi xue","volume":"36 10","pages":"1056-1062"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142717209","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}

As a representative derivative of ω-3 fatty acids, Maresin-1 has been widely explored for its role in regulating innate immune cells (neutrophils and mononuclear/macrophages) and promoting the resolution of infectious inflammation in acute inflammatory diseases. There is now increasing evidence that Maresin-1 also has a direct effect on the adaptive immune system and prevents the transition from acute inflammation to chronic inflammation. By analyzing the literature related to the effect of Maresin-1 on the regulation of inflammation, this paper summarized the role of various immune cells in inflammatory response and the regulatory mechanism of Maresin-1 on various immune cells, so as to deeply understand the research progress of the role of Maresin-1 in regulating immune cells in inflammatory diseases.
