摘要:

浸有中药伤科黄水的纱布处理伤口,药效短,需要反复用药,且易与伤口粘连,无法在吸收伤口分泌物的同时防止水分和电解质的流失等,限制了伤科黄水的应用和效果。 针对上述问题,以超亲水高分子聚乙烯醇(PVA)为原料,通过高压静电纺丝,制备了一种担载伤科黄水的聚乙烯醇静电纺丝纳米纤维创面敷料。 该创面敷料具有良好的机械性能、吸液能力和药物缓释功能,细胞毒性实验中,伤科黄水/PVA静电纺丝纳米纤维膜组的细胞存活率均在75%以上; 其中,PVA质量分数为10%、黄水质量分数为2%的静电纺丝纤维膜,具有较高的拉伸强度和弹性模量,且具有良好的延展性和吸收渗出液能力,吸液能力可达自身重量的8倍以上。 大鼠皮肤全层缺损修复实验中,该组创面敷料的愈合速度和创面修复效果明显优于伤科黄水原药组及其它低药物含量组。 该伤科黄水/PVA静电纺丝纳米纤维膜可作为一种良好的创面覆盖物,吸收创口渗出、加速皮肤缺损修复,在拓宽院内制剂中药伤科黄水的应用形式和增强其使用效果等方面具有十分广阔的前景。

Abstract:

Shangkehuangshui is a traditional chinese medicine lotion. At present, gauze impregnated with traditional Chinese medicine Shangkehuangshui is generally used in clinical treatment of wounds, which has short efficacy and needs to change the dressing repeatedly, and gauze is easy to adhere to wounds. Gauze impregnated with Shangkehuangshui cannot preventing water and electrolyte loss while absorbing wound secretions, which limits the application and effect of Shangkehuangshui in traumatology. To solve the above problems, a kind of polyvinyl alcohol (PVA) electrospinning nanofiber dressing is prepared by high pressure electrospinning using the superhydrophilic polymer PVA as raw material. Through the characterization and testing of its structure and properties, PVA/HS electrospun fiber film shows great mechanical properties, liquid absorption capacity and drug slow release function. In the test of cytotoxicity, the survival rate of cells in the Shangkehuangshui/PVA electrospinning nanofiber membrane groups are above 75%. Among them, the electrospun fiber membrane with PVA content of 10% and Shangkehuangshui content of 2% has high tensile strength and elastic modulus, and has good ductility and exudate absorption capacity, which can reach more than 8 times of its own weight. In the rat full-layer skin defect repair experiment. The healing speed and healing effect of the wound dressing in this group are significantly better than those in the Shangkehuangshui original medicine group and other low drug content groups. These results indicate that the Shangkehuangshui/PVA electrospinning nanofiber film can be used as a good wound covering, absorbing wound exudation, accelerating skin defect repair, and has a broad prospect in broadening the application form and enhancing the application effect of Shangkehuangshui in traumatology.
