摘要:


文题释义:

小型猪创伤模型:小型猪是指成年后体质量界定于45-65 kg的猪种。小型猪创伤模型是指利用小型猪模拟由多种因素引起的组织或器官结构或功能损伤模型,常见的创伤模型包括皮肤损伤、烧伤、感染伤等。
水凝胶创伤修复:水凝胶具有保水性、黏附性和多孔结构等理化性质,是一种修复创伤的药物载体。水凝胶材料不仅能为伤口提供湿性环境,并且能缓释药物为伤口提供抗菌、促进再生等效应。


背景:小型猪因皮肤组织结构、心血管系统等与人高度相似,所以常被应用于皮肤损伤、血管创伤与美容医学等研究领域。水凝胶作为创伤修复敷料拥有较强的保水性和黏附性等多种优异理化性质,能够为伤口提供隔离湿润和药物释放作用。

目的:归纳和总结水凝胶治疗小型猪不同实验用途创伤修复模型的应用进展,揭示各类小型猪创伤修复模型的发展现状,分析现阶段小型猪创伤修复模型的不足。
方法:查阅 Web of Science 数据库及中国知网从数据库建立至2023年发表的相关文献,设置中文检索词为“小猪,小型猪,微型猪,迷你猪;凝胶,水凝胶;创伤,损伤,伤口,创口”等,英文检索词为“miniature Swine,miniature pig,minipig;gel,hydrogel;injury, wound,lesion,incision”等。共检索到438篇中、英文文献,通过纳入和排除标准共纳入59篇文献进行探讨。

结果与结论:①目前用于创伤修复的模型主要有大型动物物种(犬和猪)、兔子及啮齿类动物(大鼠和小鼠),由于小型猪皮肤结构与人类较相似,因此小型猪是创伤修复理想的动物模型。②在体外皮肤损伤模型中,皮肤缺损模型是基础的伤口模型,按伤口缺损深度可分为全层皮肤缺损模型和中厚皮肤缺损模型;烧伤伤口模型和感染伤口模型是在皮肤缺损模型的基础上施加热金属烫伤和细菌培养的多维度模型,具有安全系数高、操作难度低的优点。③在体内创伤修复模型中,小型猪可用作更符合临床疾病病理状态的食管环切模型;在胃穿孔、血管止血模型中,小型猪可观地展示出水凝胶较强的脏器黏附性、止血性能及促进组织再生效应。④在猪的特定部位也有相应模式用途:猪耳通常用来评价水凝胶的药物缓释效果;猪细胞蛋白和猪皮胶原多制备组织来源的复合水凝胶。

Abstract: BACKGROUND: Minipigs are often used in research fields such as skin injury, vascular trauma and cosmetic medicine because they are highly similar to human beings in terms of skin tissue structure and cardiovascular system. Hydrogel as a wound repair drug possesses a variety of excellent physicochemical properties such as strong water retention and adhesion, which can provide isolation moisturization and drug release for wounds. 
OBJECTIVE: To summarize and conclude the progress of the application of trauma models for different experimental purposes of hydrogel therapy for minipigs, to reveal the development status of various types of minipig trauma models, to analyze the deficiencies of minipig trauma models at the present stage.
METHODS: The relevant articles published in Web of Science database and CNKI database from the establishment of each database to 2023 were checked, using “piglet, miniature pig, minipig, miniature pig; gel, hydrogel; trauma, injury, wound, lesion, incision” as Chinese search terms and “Miniature Swine, Miniature pig, minipig; gel, hydrogel; injury, wound, lesion, incision” as English search terms. A total of 438 Chinese and English documents were retrieved, and 59 documents were included in the study through the inclusion and exclusion criteria. 
RESULTS AND CONCLUSION: (1) At present, the main models used clinically for trauma repair are large animal species (dogs and pigs), rabbits, and rodents (rats and mice). Because the skin structure of the minipig is more like that of humans, the minipig is the most ideal animal model for trauma repair. (2) In the in-vitro skin injury model, skin defect model is the basic wound model, which can be divided into full skin defect model and medium-thickness skin defect model according to the depth of the wound defect. Burn wound model and infected wound model are multidimensional models with hot metal scald and bacterial culture imposed on the basis of the skin defect model, which have the advantages of high safety coefficient and low operation difficulty. (3) In the in-vivo trauma repair model, mini-pigs are used as esophageal cricothyrotomy model which is more in line with the pathological state of clinical diseases. Mini-pigs are used in the gastric perforation and vascular hemostasis model, which can visually demonstrate the stronger organ adhesion, hemostatic properties and tissue regeneration-promoting effects of the hydrogel. (4) The specific parts of the pig also has the corresponding mode of use: pig ear is usually used to evaluate the hydrogel drug delayed-release effect. Porcine cellular proteins and pig skin collagen are mostly used to prepare composite hydrogels of tissue origin.
