超声引导下关节腔内注射聚桂醇治疗血友病慢性滑膜炎的安全性及有效性研究
发布时间:2021-06-11 00:43
血友病是一种遗传性凝血因子缺乏性疾病,关节出血是较为常见的临床表现。频繁的关节出血会刺激滑膜增生、炎性细胞浸润及新生血管形成,导致血友病慢性滑膜炎。炎性滑膜血供丰富,更容易受伤后出血,形成出血-滑膜炎-再出血的恶性循环。及早去除炎性滑膜可以延缓软骨及骨质破坏、保护关节运动功能,同时减少再出血风险。文献报道关节腔内注射聚桂醇能造成类风湿关节炎滑膜坏死、纤维化,但尚无聚桂醇治疗血友病慢性滑膜炎的基础及临床研究。本实验建立血友病性关节炎动物模型,分别在血友病性关节炎动物模型及血友病患者中探究超声引导下关节腔内注射聚桂醇治疗血友病慢性滑膜炎的安全性及有效性。共包括三个部分:第一部分:血友病性关节炎动物模型的建立及超声评估。目的:向兔关节腔内分别注射血液及右旋糖酐铁建立血友病性关节炎动物模型,使用超声监测关节结构变化、评价造模效果。方法:新西兰兔25只随机分为三组,A、B每组5只,C组15只。A、B组膝关节腔注射1mL兔动脉血液,A组每周3次,持续12周,共36次,B组每周两次,持续12周,共24次;C组膝关节腔注射1mL右旋糖酐铁,按造模时间分为C1组(诱导4周)、C2组(诱导8周)、C3组(...
