摘要: 目的 利用牙周炎与类风湿关节炎小鼠模型研究牙龈卟啉单胞菌感染对类风湿关节炎的影响。方法 实验小鼠被分为单纯类风湿关节炎组与牙周炎合并类风湿关节炎组。实验中通过口腔涂抹牙龈卟啉单胞菌构建牙周炎模型,利用牛II型胶原诱导小鼠类风湿关节炎模型的建立。通过比较牙龈卟啉单胞菌感染与否对类风湿关节炎严重程度的影响来探讨牙龈卟啉单胞菌感染是否会促进类风湿关节炎的发生及发展。实验中通过类风湿关节炎评分,评估类风湿关节炎的严重程度;利用酶联免疫分析试剂盒检测血浆中类风湿关节炎相关因子的水平。结果 牙龈卟啉单胞菌感染合并胶原诱导类风湿关节炎组的类风湿关节炎症状出现时间较单纯胶原诱导类风湿关节炎组明显缩短,并且在牙龈卟啉单胞菌感染情况下的类风湿关节炎的症状及类风湿关节炎相关炎症因子如TNF-α、IL-1、IL-6、IL-17的水平也明显升高。结论 牙龈卟啉单胞菌感染能促进类风湿关节炎的发生并加重类风湿关节炎症状。

Abstract: Objective To study the effect of Porphyromonas gingivalis infection on rheumatoid arthritis in mice model. Methods The mice were divided into rheumatoid arthritis (CIA) group and periodontitis combined with rheumatoid arthritis (CIA+Pg) group. Periodontitis models were constructed by oral inoculation of Porphyromonas gingivalis, and the rheumatoid arthritis model was induced by bovine II collagen. To determine the effect of Porphyrinomonas gingivalis infection on the severity of rheumatoid arthritis, the severity of rheumatoid arthritis was assessed by rheumatoid arthritis score. The level of rheumatoid factor in plasma was detected by enzyme linked immunoassay kit. Results The onset of rheumatoid arthritis in the CIA+Pg group were significantly shorter than those of the CIA group, and the symptoms were more serious. The inflammatory factors related to rheumatoid arthritis such as TNF-α, IL-1, IL-6 and IL-17 were also significantly higher in CIA+Pg group. Conclusion The infection of Porphyromonas gingivalis can promote the occurrence of rheumatoid arthritis and aggravate the symptoms of it.
