文题释义:
膝痹:乃西医所讲的骨性关节炎,是骨科常见病,又称增生性关节炎、老年性关节炎,是一种慢性关节疾病,它的主要改变是关节软骨面的退行性变和继发性的骨质增生,主要表现是关节疼痛和活动不灵活,X射线表现关节间隙变窄,软骨下骨质致密,骨小梁断裂,有硬化和囊性变,关节边缘有唇样增生,后期骨端变形,关节面凹凸不平,关节内软骨剥落,骨质碎裂进入关节,形成关节内游离体。


 

背景:目前国内外均有采用石膏固定法复制膝痹动物模型,但存在实验动物选择不佳、石膏选取不合适、单纯石膏固定不稳定等问题,影响后续实验结果。
目的:采用石膏铁丝固定法建立兔膝痹模型。

方法:将20只新西兰大白兔随机均分为2组,模型组在应用树脂石膏屈曲位固定的基础上外层缠绕铁丝以保护石膏,建立右侧膝痹模型;对照组为正常对照。固定后8周,进行右膝关节大体观察与病理组织学观察。
结果与结论:对照组膝关节半透明,光滑,有光泽,无软骨缺损,软骨弹性及硬度好,软骨细胞排列正常,关节囊内未见炎细胞浸润;模型组膝关节无光泽,不透明,关节软骨变薄,弹性较差,关节软骨退变,关节面变粗糙,部分有缺损,关节内仅有少量关节液或无关节液,软骨细胞萎缩或消失,数量减少,软骨变性、坏死,软骨下骨组织骨质硬化,骨小梁增生,软骨细胞紊乱无序,玻璃样变,滑膜绒毛肥大,细胞成簇现象,可见大量淋巴细胞、浆细胞、中性粒细胞浸润,呈现典型的膝痹病理改变。表明采用石膏铁丝固定法能成功建立兔膝痹模型,具有简单易行、固定牢固、无创伤等优点。

Abstract:

BACKGROUND: Currently, the researches on knee plaster immobilization paralysis animal models are popular in the world, but there are some insufficiencies with the knee paralysis animals, for example, poor animal selection, inappropriate plaster selection and pure gypsum instability, which affect the subsequent results. 

OBJECTIVE: To establish a rabbit model of knee paralysis by the knee fixation with plaster casts and wire.
METHODS: A total of 20 New Zealand white rabbits were randomly divided into two groups. Models of right knee paralysis were established and fixed by plaster casts and wire. Normal controls were considered as the control group. At 8 weeks after fixation, right knee and pathologic histology were observed in the right knee. 
RESULTS AND CONCLUSION: The knee joints were translucent, smooth, and shiny, without the cartilage defect in the control group, and the cartilaginous elasticity and rigidity were good, and the arrangement of chondrocytes was normal. There were no inflammatory infiltrations in the articular capsule of the normal rabbits. In the model group, the knee joint was matt and opaque. Articular cartilage became thin, and showed poor elasticity. The cartilages were degenerated. Articular surface was rough, and had defects. There were small amount of joint fluid orno joint fluid. Cartilage cells shrank or disappeared, and the number of cartilage cells reduced with degeneration and necrosis. Subchondral bone became sclerosis with trabecular bone of hyperplasia. The arrangement of cartilage cells was disordered, with hyalinization and synovial villous hypertrophy. Cell clustering phenomenon was seen. There were a large number of lymphocytes, plasma cells and neutrophil infiltration in cartilages. The typical pathological changes of the knee paralysis present in the rabbit cartilage. These results demonstrate that the rabbit model of knee paralysis can be successfully established by using fixation method with plaster casts and wire, which has the advantages of simple operation, strong fixation and no injury.
