Abstract

Infection caused by bacteria is one of the crucial risk factors for tendon adhesion formation. Silver nanoparticles (AgNP)-loaded physical barriers were reported to be effective in anti-infection and anti-adhesion. However, high silver load may lead to kidney and liver damages. This study was designed for Ibuprofen (IBU)-loaded poly(L-lactide) (PLLA) electrospun fibrous membranes containing a low dosage of Ag to evaluate its potential in maintaining suitable anti-infection and good anti-adhesion effects. The in vitro drug release study showed a sustained release of Ag ions and IBU from the membrane. Inferior adherence and proliferation of fibroblasts were found on the Ag4%-IBU4%-loaded PLLA electrospun fibrous membranes in comparison with pure PLLA and 4% Ag-loaded PLLA membranes. In the antibacterial test, all Ag-loaded PLLA electrospun fibrous membranes prevented the adhesion of Staphylococcus aureus and Staphylococcus epidermidis. Taken together, these results demonstrate that Ibuprofen is effective in enhancing the anti-adhesion and anti-proliferation effects of 4% Ag-loaded PLLA fibrous membrane. The medical potential of infection reduction and adhesion prevention of Ag4%-IBU4%-loaded PLLA electrospun fibrous membrane deserves to be further studied.

摘要

细菌感染是肌腱粘连形成的关键危险因素之一。据报道，负载银纳米颗粒（AgNP）的物理屏障在抗感染和抗粘连方面有效。然而，高银负载量可能会导致肾脏和肝脏损伤。本研究旨在制备负载布洛芬（IBU）的聚（L-丙交酯）（PLLA）电纺纤维膜，其含有低剂量的银，以评估其在维持适当抗感染和良好抗粘连效果方面的潜力。体外药物释放研究表明，银离子和布洛芬从该膜中持续释放。与纯PLLA和负载4%银的PLLA膜相比，在负载4%银-4%布洛芬的PLLA电纺纤维膜上发现成纤维细胞的粘附和增殖较差。在抗菌试验中，所有负载银的PLLA电纺纤维膜均能防止金黄色葡萄球菌和表皮葡萄球菌的粘附。综上所述，这些结果表明布洛芬在增强负载4%银的PLLA纤维膜的抗粘连和抗增殖作用方面是有效的。负载4%银-4%布洛芬的PLLA电纺纤维膜在减少感染和预防粘连方面的医学潜力值得进一步研究。
