摘要： 目的 通过建立兔肝脏出血模型,研究负载PRP壳聚糖-明胶复合敷料（CMC/ GMs/PRP敷料）的止血和促愈合效果。方法 将20只健康新西兰兔随机分4组,每组5只。分别为空白对照组（A组）,实验组（B组）、阴性对照组（C组,创口敷普通纱布）、阳性对照组（D组,创口敷术益纱敷料）。建立兔肝脏出血模型后,记录每只兔的止血时间和出血量,并于术后第1、2、3、4 周时进行主要血液学指标检测及组织学评价。结果 CMC/GMs/PRP复合敷料的止血时间和出血量均少于其它三个对照组,其差异有统计学意义（P<0.05）。动态观察愈合过程中实验组白细胞变化最小,实验组肝损伤后的修复效果和安全性均优于其它组。结论 负载PRP壳聚糖-明胶复合敷料具有良好的止血和促进创面愈合的作用,且有较高的安全性,具有进一步研究的价值和应用前景。

Abstract: Objective To study the hemostatic and effects of wound healing using chitosan-gelatin composite dressing loaded with platelet rich plasma（PRP）（CMC/GMs/PRP dressing） in a rabbit model of liver hemorrhage. Methods Twenty healthy New Zealand rabbits were randomly divided into 4 groups with 5 rabbits in each group：group A：control group,group B：CMC/GMs/PRP group,group C：negative control group （ordinary gauze）,group D：positive control group（Muyisha gauze）. The rabbit liver hemorrhage model was established. The hemostasis time and the amount of bleeding were recorded. The main hematological indicators and histological evaluations were performed at the first 1,2,3,4 weeks after the operation. Results The hemostasis time and bleeding volume in the CMC/GMs/PRP group were less than those in other three control groups（P<0.05）. During wound healing process,changes in white blood cell counts in the CMC/GMs/PRP group were minimal and repair of liver injury and safety in the CMC/GMs/PRP group were both better than those in other groups. Conclusion The PRP chitosan-gelatin composite dressing is capable of hemostasis and promoting wound healing, and also is safety. It has further research value and application prospects.
