摘要: 目的: 检测细胞外基质金属蛋白酶诱导因子(CD147)和亲环素A(CypA)在根尖肉芽肿和根尖囊肿中的表达,探讨CD147和CyPA在人慢性根尖周炎发生发展中的作用。方法: 收集经根尖手术切除所获得的根尖肉芽肿35例和根尖囊肿30例作为实验组,同时收集埋伏阻生智齿拔除术或行牙槽骨修整术凿下的8例健康牙槽骨作为正常对照组。CBCT图像记录病例的病损大小。运用免疫组织化学法检测所有样本中CD147和CypA的蛋白表达,分析CD147和CypA的蛋白表达水平。结果: 根尖囊肿组两种蛋白的表达水平均高于肉芽肿组(P<0.05)。CD147和CypA 的蛋白表达水平在根尖囊肿和根尖肉芽肿中呈正相关(P<0.05);CD147和CypA 的表达水平均与慢性根尖周炎的病变大小呈正相关(P<0.05)。结论: CD147和CypA可能参与根尖周病损的炎性反应和骨质吸收。CD147-CypA相互作用在人慢性根尖周病的发生发展过程中可能发挥了某种协同作用。

Abstract: Objective: To investigate the expression of extracellular matrix metalloproteinase inducer (CD147) and Cyclophilin A (CypA) in periapical granulomas (PGs) and radicular cysts (RCs). The interaction of CD147 with CypA and their roles in periapical pathogenesis were also speculated. Methods: Thirty PGs and thirty-five RCs were collected after periapical surgery as the experimental samples. Eight alveolar bone samples were obtained from extraction of impacted third molars or alveoloplasty as the control samples. The lesion size was recorded by CBCT. The protein expression of CD147 and CypA was observed by immunohistochemical analysis for all samples. Statistical analysis was performed to evaluate the differences of expression of CD147 and CypA. Results: The expression of CD147 and CypA in RCs were higher than in PGs (P<0.05). Positive correlations between CD147 and CypA protein levels were observed in PGs and RCs (P<0.05), respectively. Furthermore, the expression of CD147 and CypA was positively correlated with the lesion size (P<0.05). Conclusion: These findings demonstrated that CD147 and CypA might be involved in the inflammatory response, bone resorption of periapical lesions tissues. The CD147-CypA interactions may play a synergistic role in the development and progression of periapical lesion.
