Plain-English summary
Researchers have been working on improving a type of mesh used in breast reconstruction surgery to help patients heal better and faster. They created a special polypropylene (PP) mesh that has been treated with a laser and infused with a drug called triclosan, which helps reduce inflammation and fight bacteria. In tests on female rats, this new mesh led to quicker healing and better blood vessel growth around the surgical area. The results showed that the mesh not only helped wounds heal faster but also reduced inflammation markers in the body. Overall, this new approach seems to improve the effectiveness of PP meshes in medical use.
Abstract
Polypropylene (PP) mesh implanting has emerged as a breast reconstruction approach to restore normal anatomical contours. However, developing biomedical PP mesh with enhanced anti-inflammatory properties, superior mechanical strength, and efficient manufacturing remains a significant challenge. In this study, we report a drug-loading PP mesh by incorporating triclosan into femtosecond (fs) laser-treated PP mesh scaffolds. The fs laser induced micro/nano structures significantly enhanced the drug-loading capacity and antibacterial efficacy of triclosan-modified PP mesh, as indicated by the area of inhibition rings (2.5-fold relative to the blank groups). In vivo breast reconstruction experiments using female Sprague-Dawley (SD) rats demonstrate accelerated scab formation and wound healing. Additionally, the Enzyme-linked immunosorbent assay (ELISA) test reveals high vascular density (11.43 µg/mL of CD31 and 0.32 µg/mL of CD163) and reduced proinflammatory cytokine levels (145 pg/mL of IL-6 and 33 pg/mL of TNF-a), further confirming the anti-inflammatory properties of the fs laser-treated triclosan-modified PP mesh. This study presents a novel approach to improving the clinical performance of PP meshes for biomedical applications.
