J Endod:血糖正常和糖尿病大鼠根尖周炎的Th1/Th2/Th17/Treg平衡研究

2019-07-03 lishiting MedSci原创

这篇研究的目的是为了评估血糖正常(N)和糖尿病大鼠罹患根尖周炎(AP)时T辅助(Th)细胞的炎症特征。

这篇研究的目的是为了评估血糖正常(N)和糖尿病大鼠罹患根尖周炎(AP)时T辅助(Th)细胞的炎症特征。研究将20只Wistar大鼠随机分为2组:N大鼠和糖尿病大鼠(DM)。DM通过链脲霉素诱导形成,AP通过暴露下颌第一磨牙髓腔至口腔环境中诱导而来。30天后,提取下颌骨并进行组织学检测、细菌化验以及免疫化学分析白细胞介素(IL)-6, 肿瘤坏死因子a, IL-17, IL-23, 干扰素r和IL-10。采用Mann-Whitney U和Student t检验进行统计学分析(P < .05)。结果显示,DM组的炎症浸润程度比N组更加强烈,并且骨吸收范围更大以及细菌更多(P < .05)。DM组的促炎症因子水平比N组更高(P < .05)。然而,N组干扰素r水平要明显高于DM组(P < .05)。结论:DM组AP的炎症特征与N组差异明显,表明在DM中Th1是二级应变而Th17是起主导作用的一级应变。原始出处:Samuel RO, Ervolino E, et al.
