摘要:


文题释义:

医用臭氧:臭氧是一种由3个氧原子组成的强氧化剂,它具有刺激氧化酶过度表达、中和炎症反应中产生的过量反应性氧化物、抑制炎症反应时细胞因子释放及通过改变关节腔内环境促进关节软骨修复和再生的作用,临床上一般采用关节腔内注射医用臭氧的方法以减缓骨关节炎症状和改善关节功能。
碘乙酸钠:是目前动物实验中骨关节炎建模时最常用来注射的化合物,是甘油醛-3-磷酸脱氢酶活性的抑制剂,可诱导软骨细胞凋亡,引起软骨基质改变、软骨降解丢失、滑膜炎症等病理改变。


背景:在临床以及动物实验中均已证实关节腔内注射医用臭氧可有效改善颞下颌关节炎的症状,减缓疾病的发展,但注射医用臭氧的最理想浓度及其范围仍有争议。

目的:观察颞下颌关节腔内注射不同质量浓度医用臭氧对颞下颌骨关节炎大鼠髁突软骨的影响。
方法:从42只SD大鼠中随机抽取6只作为健康对照组,剩余大鼠采用关节腔内一次性注射碘乙酸钠法建立颞下颌骨关节炎模型,在建模成功的36只大鼠中选择6只作为模型参照组,其余的30只为20,30,40 mg/L医用臭氧组,每组10只。建模成功后医用臭氧组大鼠关节腔内分别注射质量浓度为20,30,40 mg/L医用臭氧,每周1次,连续注射3周,模型参照组和健康对照组分别注射等体积生理盐水,末次注射后1周,取单侧颞下颌关节组织,ELISA法检测髁突软骨中血管内皮生长因子水平,并取另一侧颞下颌关节组织进行苏木精-伊红染色和番红O-固绿染色,应用改良Mankin’s评分法评价颞下颌关节组织病理变化程度。

结果与结论:①与健康对照组相比,模型参照组、医用臭氧20,30,40 mg/L组大鼠髁突软骨中血管内皮生长因水平显著升高(P <  0.05);与模型参照组、医用臭氧40 mg/L组相比,医用臭氧20,30 mg/L组髁突软骨中血管内皮生长因子水平明显下降(P < 0.05);与医用臭氧30 mg/L组相比,医用臭氧20 mg/L组髁突软骨中血管内皮生长因子水平较低(P < 0.05);②组织学观察结果显示医用臭氧20,30,40 mg/L组及模型参照组改良Mankin’s评分均高于健康对照组(P < 0.05),医用臭氧20,30 mg/L组改良Mankin’s评分低于模型参照组、医用臭氧40 mg/L组(P < 0.05);③结果表明,关节腔内注射质量浓度分别为20,30 mg/L医用臭氧时,能明显缓解大鼠颞下颌骨关节炎的进展,尤其是注射20 mg/L医用臭氧时效果更佳,但是当臭氧质量浓度上升到40 mg/L时,反而会加重大鼠颞下颌骨关节炎的病变程度。

Abstract: BACKGROUND: It has been proved in clinical and animal experiments that intraarticular injection of medical ozone can effectively improve the symptoms of temporomandibular joint osteoarthritis and slow down the progression of the disease. However, the optimal concentration and range are still controversial.
OBJECTIVE: To analyze the effects of intraarticular injection of different concentrations of medical ozone on the condylar cartilage of rats with temporomandibular joint osteoarthritis. 
METHODS: Of the 42 rats, 6 rats were randomly selected as the healthy control group, and the remaining rats were given one-time injection of sodium iodoacetate into the joint cavity to establish the temporomandibular joint osteoarthritis model. Of the 36 rats successfully modeled, 6 rats were selected as the model control group, and the remaining 30 were randomly divided into 20, 30, 40 mg/L medical ozone groups, with 10 rats in each group. After successful modeling, the rats in the medical ozone groups were given intra-articular injection of 20, 30, 40 mg/L medical ozone oxygen once a week for 3 weeks, respectively, and the model and healthy control groups were injected with equal volume of saline. One week after the final injection, unilateral temporomandibular joint tissues were taken, and the level of vascular endothelial growth factor in condylar cartilage was measured by ELISA. Hematoxylin-eosin staining and saffron O-fast green staining were performed on the contralateral temporomandibular joint tissues. The modified Mankin’s score was applied to evaluate the degree of histopathological changes in the temporomandibular joint.
RESULTS AND CONCLUSION: Compared with the healthy control group, the vascular endothelial growth factor level in the condylar cartilage of rats was significantly increased in the model control and 20, 30, 40 mg/L medical ozone groups (P < 0.05). Compared with the model control group and 40 mg/L medical ozone group, the vascular endothelial growth factor level in the condylar cartilage of rats was significantly decreased in the 20 and 30 mg/L medical ozone groups (P < 0.05). Compared with the 30 mg/L medical ozone group, the vascular endothelial growth factor level in the condylar cartilage of rats was significantly decreased in the 20 mg/L medical ozone group (P < 0.05). Histological observations showed that the modified Mankin’s scores in the 20, 30, and 40 mg/L medical ozone groups and the model control group were higher than those in the healthy control group (P < 0.05), while the modified Mankin’s scores in the 20 and 30 mg/L medical ozone groups were lower than those in the model control group and the 40 mg/L medical ozone group (P < 0.05). To conclude, intraarticular injection of medical ozone at mass concentrations of 20 and 30 mg/L significantly alleviated the progression of osteoarthritis of the temporomandibular joint in rats, especially when 20 mg/L medical ozone was injected. However, the degree of osteoarthritis in the temporomandibular joint of rats was aggravated when the mass concentration of ozone increased to 40 mg/L.
