摘要:

文题释义:

颞下颌关节骨关节炎:颞下颌关节是连接下颌骨与颅骨的关节,颞下颌关节骨关节炎属于颞下颌关节紊乱病,可引起头痛、颈痛、面部疼痛、耳痛等症状。有报告指出11%的人群患有颞下颌关节骨关节炎。
医用臭氧:为淡蓝色极不稳定的气体,可以溶于血液和组织液,由德国化学家先贝因博士提出,适合浓度的医用臭氧可杀灭多种病原菌,对炎症及其疼痛的治疗具有良好疗效。


背景:颞下颌关节骨关节炎引起的疼痛严重影响了患者的生活质量及心理健康。研究发现医用臭氧能有效缓解颞下颌关节骨关节炎疼痛,但对其镇痛作用及机制尚不清楚。

目的:探讨医用臭氧对颞下颌关节骨关节炎疼痛的作用及可能机制。
方法:采用随机数字表法将24只SD大鼠分成4组,每组6只,除对照组外,模型组、空气组、医用臭氧组通过关节内注射碘乙酸钠的方法建立颞下颌关节骨关节炎模型,造模1周后,空气组、医用臭氧组大鼠颞下颌关节内分别注射洁净空气、医用臭氧,1次/周,共3次。造模前及造模后28 d内,采用Von Frey机械疼痛测量技术衡量大鼠颞下颌关节机械痛阈值;造模后28 d取材,应用ELISA法检测血清和颞下颌关节液中白细胞介素1β水平,苏木精-伊红染色观察颞下颌关节软骨组织病理学变化,免疫组化染色分析颞下颌关节内缺氧诱导因子1α、环氧合酶2表达水平。

结果与结论:①与对照组相比,模型组大鼠造模后1,3,7,14,21,28 d的颞下颌关节机械痛阈值降低(P < 0.01);与模型组、空气组相比,医用臭氧组大鼠造模后28 d的颞下颌关节机械痛阈值升高(P < 0.01);②与对照组相比,模型组大鼠血清与关节液中的白细胞介素1β质量浓度升高(P < 0.01);与模型组、空气组相比,医用臭氧组大鼠血清与关节液中的白细胞介素1β质量浓度降低(P < 0.01);③苏木精-伊红染色显示模型组和空气组软骨结构紊乱,呈退行性改变;医用臭氧组软骨结构紊乱程度轻于模型组、空气组;④免疫组化染色显示,与对照组相比,模型组大鼠颞下颌关节内缺氧诱导因子1α、环氧合酶2表达升高(P < 0.01);与模型组、空气组相比,医用臭氧组大鼠颞下颌关节内缺氧诱导因子1α、环氧合酶2表达降低(P < 0.01,P < 0.05)。结果表明,医用臭氧可通过减少关节内缺氧诱导因子1α、白细胞介素1β和环氧合酶2表达来缓解SD大鼠颞下颌关节骨关节炎引起的疼痛。

Abstract: BACKGROUND: Temporomandibular joint osteoarthritis can cause severe pain, which significantly affects the patient’s quality of life and psychological health. Studies have found that medical ozone can effectively alleviate pain due to temporomandibular joint osteoarthritis, but its analgesic effect and mechanism are still unclear. 
OBJECTIVE: To explore the effects of medical ozone on pain relief in temporomandibular joint osteoarthritis and the potential mechanisms.
METHODS: Twenty-four Sprague-Dawley rats were randomly divided into four groups (n=6 per group): control group, model group, air group, and medical ozone group. A sodium iodate-induced rat model of temporomandibular joint osteoarthritis was established in all groups except for the control group. After 1 week of modeling, rats in the air group and medical ozone group were injected with clean air and medical ozone, respectively, in the temporomandibular joint. The injection frequency for the air group and medical ozone group was once a week for three times in total. The von Frey mechanized pain measurement technique was used to assess the mechanical pain threshold of the temporomandibular joint in rats before and 28 days after modeling. ELISA was utilized to detect interleukin-1β in both serum and temporomandibular joint fluid at 28 days after modeling. Histopathologic changes of the temporomandibular joint were evaluated through hematoxylin-eosin staining. Additionally, the expression levels of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joint were analyzed using immunohistochemistry.
RESULTS AND CONCLUSION: Compared with the control group, the mechanical pain thresholds of the temporomandibular joint in the model group were decreased at 1, 3, 7, 14, 21, and 28 days after modeling (P < 0.01); and compared with the model and air groups, the mechanical pain thresholds of the temporomandibular joint in the medical ozone group were increased at 28 days after modeling (P < 0.01). Compared with the control group, the level of interleukin 1β in the serum and joint fluid of rats in the model group was elevated (P < 0.01); compared with the model and air groups, the level of interleukin 1β in the serum and joint fluid of rats in the medical ozone group was decreased (P < 0.01). Hematoxylin-eosin staining results showed derangement and degeneration of the cartilage structure in the model group and the air group, while the derangement of the cartilage structure in the medical ozone group was less than that in the model group and the air group. Immunohistochemical staining showed that the expression of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joints of rats in the model group was elevated compared with that in the control group (P < 0.01); the expression of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joints of rats in the medical ozone group was decreased compared with that in the model group and the air group (P < 0.01, P < 0.05). These findings suggest that medical ozone can alleviate the pain caused by osteoarthritis of the temporomandibular joints in Sprague-Dawley rats by reducing the expression of hypoxia-inducible factor 1α, interleukin 1β, and cyclooxygenase 2.
