Circulating neutrophils from one healthy mouse were stimulated with phorbol myristate acetate (PMA) (in vitro control group) or PMA+BCA (in vitro experimental group) for 4 hours to induce the inflammatory state of neutrophils, and the culture medium was obtained through centrifugation. The culture medium from the in vitro control group and in vitro experimental group was used to cultivate H9C2 cardiomyocytes to induce their injury. The inhibitory effect of BCA on the injury of cardiomyocytes by neutrophils was evaluated by Western blotting for apoptosis-related proteins BCL2-associated X protein (Bax) and Cleaved caspase 3. &lt;b&gt;Results:&lt;/b&gt; Compared with the BCA-MI control group, the BCA-MI experimental group exhibited a smaller infarct","PeriodicalId":24023,"journal":{"name":"Zhonghua yi xue za zhi","volume":"105 18","pages":"1414-1421"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144040000","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}
