In group S, the relevant tissues around the liver were dissociated only. Orthotopic autologous liver transplantation was used in other groups, berberine 200 mg/kg/day was given one week before surgery in group B and group B+G. GW9662 1 mg/kg was intraperitoneally injected in group G and group B+G 4 hours before surgery. Blood samples were obtained for detecting PaO2 and the concentration of serum clam cell protein (CC16), surfactant protein-D (SP-D), interleukin (IL)-1β and IL-18. The immunohistochemical method detects the expression of PPARγ and nuclear factor-kappa B (NF-κB) in lung tissues. The expression of PPARγ, NF-κBand pyroptosis-related proteins were analysed by western blotting.Results: Rats exhibited increased histological lung injury following OALT. Liver transplantation caused upregulated CC16, SP-D, IL-18 and IL-1β levels, reduced PaO2 and the PPARγ expression, upregulated the NF-κB and pyroptosis-related protein expressions. BBR pretreatment greatly alleviates these lung damages induced by OALT. However, administration of GW9662 partially reversed the beneficial effects of BBR on lung injury.Conclusion: Berberine may play protective capacities against lung injury by upregulating PPARγ to downregulate the NF-κB-mediated pyroptosis pathway.","PeriodicalId":93850,"journal":{"name":"Acta cirurgica brasileira","volume":"40 ","pages":"e404925"},"PeriodicalIF":1.3,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12302298/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144746447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The meshes were cut to a size of 10 cm in length by 1 cm in width. A longitudinal, median abdominal incision, 11 cm in length, was performed, followed by an incision over the linea alba, encompassing the entire thickness of the abdominal wall. On the 91st postoperative day, the animals were killed for linea alba scar evaluation.Results: There was a significant difference among the evaluated groups concerning elongation, maximum load, and elasticity modulus. HWMR and LWMR were statistically different from controls regarding elongation. As for the elasticity modulus, SR presented a higher mean when compared to the others. Microscopic visual analysis showed greater fibrotic scarring with a larger amount of implanted material in HWMR.Conclusion: The reinforcement of scars with polypropylene mesh does not increase tensile strength when compared to the use of sutures. Mesh implantation results in scar remodeling with greater fibrosis, leading to increased elongation.
