壳聚糖基水凝胶在皮肤创口修复中的应用研究

Study on the Application of Chitosan-Based Hydrogels in Skin Wound Repair

摘要: 壳聚糖作为一种天然线性多糖，拥有许多独特的性质，这些性质使得其成为生物医学领域重点研究的对象。首先，壳聚糖具有一定的生物活性，这种性质能够促进细胞增殖和组织修复，对于加速创口愈合具有重要意义。其次，壳聚糖还有优越的抗菌能力，能抑制多种细菌的生长，有效防止创口感染。而使壳聚糖基水凝胶能够安全可靠地应用于人体的，则是壳聚糖良好的生物相容性，这种性质能有效减少人体的免疫反应及毒性反应。使用壳聚糖制成的壳聚糖基水凝胶，除了拥有上述壳聚糖的性质外，还拥有高吸水性、柔软性和可变形性等多种性质。其中，高吸水性使得创口环境能够保持湿润，有助于促进创口愈合；柔软性让其能够紧密贴合创面，为创口提供良好保护；可变形性则通过改变水凝胶的自身形状，在创口修复中更好地模拟人体皮肤，从而促进组织的再生和修复。这种性质使得壳聚糖基水凝胶成为制作皮肤创口敷料的理想材料，在多种类型的皮肤创伤修复中，表现出了显著的优越性。

Abstract: As a natural linear polysaccharide, chitosan has many unique properties, which make it the focus of biomedical research. Firstly, chitosan has certain biological activity, which can promote cell proliferation and tissue repair, and is of great significance for accelerating wound healing. Secondly, chitosan has superior antibacterial ability, which can inhibit the growth of a variety of bacteria and effectively prevent wound infection. What makes chitosan-based hydrogels safe and reliable to be applied to human body is the good biocompatibility of chitosan, which can effectively reduce the immune reaction and toxic reaction of human body. The chitosan-based hydrogels made of chitosan have many properties, such as high water absorption, softness and deformability, in addition to the properties of chitosan mentioned above. Among them, high water absorption keeps the wound environment moist, which helps to promote wound healing; The softness makes it fit tightly to the wound, providing good protection for the wound; Deformability can better simulate human skin in wound repair by changing the hydrogel’s own shape, thus promoting tissue regeneration and repair. This kind of property makes chitosan-based hydrogels an ideal material for making skin wound dressings, showing remarkable superiority in many types of skin wound repair.
