摘要: 目的: 探讨葛根素通过白细胞介素-23(IL-23)/辅助性T 细胞17(Th17)炎症轴对大鼠牙周炎牙槽骨吸收的作用及对骨保护素(OPG)/核因子κB配体(RANKL)/NF-κB受体活化因子(RANK)通路的影响。方法: 构建牙周炎大鼠模型,将SD雄性大鼠随机分为对照组、模型组、葛根素组,每组各20只。葛根素连续给药14 d后,观察各组大鼠牙周组织病理变化及釉牙骨质界至牙槽嵴顶的距离(CEJ-AC);通过HE染色和抗酒石酸酸性磷酸酶(TRAP)染色计数破骨细胞,流式细胞术检测外周血中Th17细胞比例,ELISA法检测血清IL-23、白细胞介素-17(IL-17)表达,通过Western blot法检测牙周组织中OPG、RANKL、RANK蛋白表达。结果: 与对照组相比,模型组和葛根素组CEJ-AC、破骨细胞、Th17细胞比例、血清 IL-23、IL-17水平、RANKL、RANK、RANKL/OPG蛋白水平显著升高(P<0.05),OPG蛋白水平显著降低(P<0.05);与模型组相比,葛根素组CEJ-AC、破骨细胞、Th17细胞比例、IL-23、IL-17水平、RANKL、RANK、RANKL/OPG蛋白水平显著降低(P<0.05),OPG蛋白水平显著升高(P<0.05)。结论: 葛根素可能通过IL-23/Th17炎症轴上调OPG表达,下调RANKL、RANK蛋白表达,控制牙槽骨吸收,促进牙周炎大鼠牙槽骨的修复和重建。

Abstract: Objective: To investigate the effects of Puerarin on alveolar bone resorption and protein osteoprotegerin (OPG)/nuclear factor κB ligand (RANKL)/NF-κB receptor activating factor (RANK) pathway in rats with periodontitis through interleukin 23 (IL-23)/T helper cell 17 (Th17) inflammatory axis. Methods: The SD male periodontitis rats were set up and randomly divided into control group, model group, and puerarin group, with 20 in each group. After 14 days of Puerarin administration, the pathological changes of periodontal tissues and cementum enamal junction to alveolar crest (CEJ-AC) were observed; osteoclasts were counted by HE staining and tartrate resistant acid phosphatase (TRAP) staining, the proportion of Th17 cells in peripheral blood was detected by flow cytometry, the expressions of IL-23 and interleukin 17 (IL-17) in serum were detected by ELISA, and Western blot was used to detect the expressions of OPG, RANKL and RANK in periodontal tissues. Results: Compared with the control group, the CEJ-AC, osteoclast, Th17 cell ratios, serum IL-23, IL-17 levels, RANKL, RANK, and RANKL/OPG protein levels in the model group and puerarin group were significantly higher (P<0.05), while the level of OPG protein was significantly lower (P<0.05); compared with the model group, the CEJ-AC, osteoclast, Th17 cell ratios, serum IL-23, IL-17 levels, RANKL, RANK, and RANKL/OPG protein levels in puerarin group were significantly lower (P<0.05), while the level of OPG protein was significantly higher (P<0.05). Conclusion: Puerarin may up-regulate OPG expression, down-regulate RANKL and RANK protein expressions through IL-23/Th17 inflammatory axis, so as to control alveolar bone absorption, and promote alveolar bone repair and reconstruction in rats with periodontitis.
