摘要:

文题释义:
膝关节滑膜炎:指没有特异性病因的膝关节滑膜炎症,主要由滑膜巨噬细胞等产生的炎症因子所介导。其发病主要与膝关节的退行性病变及关节损伤有关,临床上主要表现为膝关节肿胀、疼痛等。
苏木精-伊红染色:石蜡切片技术里常用的染色法之一。苏木精染液为碱性,主要使细胞核内的染色质与胞质内的核酸着紫蓝色;伊红为酸性染料,主要使细胞质和细胞外基质中的成分着红色。

背景:目前膝骨关节炎滑膜炎动物模型主要为手术创伤模型和关节注射诱导模型,造模方式与疾病发生方式仍有较大距离。
目的:基于“损伤-修复-再损伤”方法制备兔膝骨关节炎滑膜炎模型并对其进行评价,为研究膝骨关节炎滑膜炎提供模型支持。
方法:将16只雄性新西兰大白兔随机分为2组,模型组、对照组各8只,分别在第1,4,7,12天对模型组兔右膝关节注射4%木瓜蛋白酶和0.03 mol/L的L-半胱氨酸混合溶液以制备膝骨关节炎滑膜炎模型,期间记录兔右膝肤温,于第15天麻醉处死取材。通过膝关节MRI观察关节积液及软骨情况,苏木精-伊红染色观察滑膜组织变化,ELISA测定膝关节滑液炎症因子和前列腺素E2表达水平改变。
结果与结论:①模型组兔膝关节首次注射配制剂即出现明显红肿热情况,肤温明显高于对照组;②模型组兔膝关节MR造影显示滑膜积液渗出明显及软骨出现轻度损伤;苏木精-伊红染色呈现滑膜组织明显增厚,且有大量炎症细胞浸润;③模型组兔滑膜滑液炎症水平明显高于对照组,同时疼痛指标前列腺素E2也明显增高;④提示通过对兔膝关节表面情况、膝关节肤温、滑膜积液渗出、滑膜组织学改变及膝关节滑液炎症水平变化综合评价发现,“损伤-修复-再损伤”方法能成功制备出兔膝骨关节炎滑膜炎模型,与临床膝骨关节炎滑膜炎现象相似。

Abstract: BACKGROUND: At present, surgical trauma and intraarticular injection-induced models are the animal models mainly used for synovitis in knee osteoarthritis. There is still a large distance between the modeling method and the mode of disease occurrence.
OBJECTIVE: To establish and evaluate a rabbit model of synovitis in knee osteoarthritis based on the method of “injury-repair-re-injury,” so as to provide model support for the study of synovitis in knee osteoarthritis.
METHODS: Sixteen New Zealand white rabbits were randomly divided into two groups: model group (n=8) and control group (n=8). The rabbit’s right knee was injected with 4% papain and 0.03 mol/L L-cysteine to establish the model of synovitis in knee osteoarthritis on days 1, 4, 7, and 12. The skin temperature of the right knee was recorded. Rabbits in each group were killed under anesthesia and the knee joint samples were collected on day 15. Knee joint effusion and cartilage were observed using magnetic resonance imaging. Synovial tissue changes were observed using hematoxylin-eosin staining. Expression levels of inflammatory factors and prostaglandin E2 in the knee synovial fluid were measured by enzyme-linked immunosorbent assay.
RESULTS AND CONCLUSION: In the model group, the rat knees became red, swollen and hot obviously at the first injection of the preparation, and the skin temperature was significantly higher than that in the control group. Magnetic resonance imaging revealed obvious synovial effusion and slight damage to the knee cartilage in the model group. Hematoxylin-esoin staining showed synovial tissue thickening and a large number of inflammatory cells infiltrated in the model group. Levels of inflammatory factors and prostaglandin E2 in the synovial fluid were significantly higher in the model group than the control group. Rabbit model of synovitis in knee osteoarthritis can be successfully established by the “injury-repair-reinjury” method, which presents similar conditions with clinical synovitis in knee osteoarthritis, by comprehensive evaluation based on the performance of knee joint surface, skin temperature of the knee, synovial effusion and histological changes of the synovial tissue.
