摘要:

市售鼻腔止血海绵存在止血效率低下、不可降解和伤口感染等问题。 因此,为了应对市场和临床需求,开发具有可降解性、促凝血、抗菌和抗氧化等性能的鼻腔止血海绵尤为重要。 原儿茶醛(PA)和铁离子(Fe3+)形成的络合物PA@Fe具有促进凝血、活性氧清除和抗菌的能力。 对此,以2种多糖酰肼海藻酸钠(SA-ADH)和氧化透明质酸钠(OHA)为海绵基本骨架,掺入不同体积分数的PA@Fe,内部以席夫碱键构成交联网络设计得到一种促进凝血,具有抗菌、抗氧化特性的鼻腔填塞止血海绵(SO-PA@Fe)。 通过傅里叶变换红外光谱(FT-IR)和扫描电子显微镜(SEM)对SO-PA@Fe海绵的官能团和表面形貌进行表征,同时测试添加不同体积分数的PA@Fe对海绵的压缩强度、活性氧清除能力、抗菌特性和促凝作用的影响。 随着PA@Fe体积分数的增加,海绵的机械性能提高了31.3%。 此外,SO-PA@Fe海绵的活性氧清除最高可至62.4%,对金黄色葡萄球菌和大肠杆菌的抗菌特性高达97%,与市售明胶止血海绵相比,SO-PA@Fe海绵的血液吸收速率是其1.8倍。 综上所述,SO-PA@Fe海绵表现出优异的凝血、活性氧清除和抗菌特性,为治疗鼻窦炎术后止血修复提供了新的策略。

Abstract:

Commercially available nasal hemostatic sponges suffer from inefficient hemostasis, non-degradability, and wound infection. Therefore, in order to respond to the market and clinical needs, it is particularly important to develop nasal hemostatic sponges with degradability, procoagulant, antimicrobial and antioxidant properties. Protocatechuic aldehyde (PA) and iron ion (Fe3+) produce the complex PA@Fe, which has antimicrobial, coagulation-promoting, and reactive oxygen species-clearing capabilities. In this regard, the basic sponge skeleton was composed of two varieties of polysaccharide hydrazide sodium alginate (SA-ADH) and sodium hyaluronate oxide (OHA), with varying concentrations of PA@Fe. By creating a cross-linked network with Schiff base connections inside the nasal cavity, a hemostatic sponge with antibacterial and antioxidant qualities was created to encourage coagulation. Using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) to evaluate of the sponge's surface shape and functional groups while experimenting with the addition of various contents of PA@Fe the effect on the sponge's coagulation-promoting capacity, antimicrobial qualities, compressive strength, and capacity to scavenge reactive oxygen species. The sponge's mechanical qualities improved by 31.3% as a result of the content of PA@Fe increase. Furthermore, up to 62.4% of reactive oxygen species can be eliminated by the SO-PA@Fe sponge, and it has up to 97% antibacterial activity against Escherichia coli and Staphylococcus aureus. In contrast to gelatin hemostatic sponges that are sold commercially, SO-PA@Fe sponge absorbs blood twice as quickly. In summary, SO-PA@Fe sponge exhibits excellent coagulation, reactive oxygen species scavenging, and antibacterial properties, providing a new strategy for postoperative hemostasis and repair of sinusitis.
