摘要： 目的 研究益气活血养阴解毒方对放射性肺损伤中转化生长因子-β1(TGF-β1)、肿瘤坏死因子-α(TNF-α)表达的影响, 探讨其对放射性肺损伤的防治作用及机制。方法 将小鼠随机分为对照组(n=21)、中药组(n=21)、照射组(n=21)、治疗组(照射+中药, n=21), 用直线加速器对后两组小鼠全肺进行单次照射(12 Gy), 分别于照射后1、24、72 h和2、4、8、24周处死小鼠, 取标本进行组织学观察、RT-qPCR及免疫组化检测, 观察小鼠组织学变化及不同时间点的TGF-β1、TNF-α的表达。结果 益气活血养阴解毒方可以改善放射性肺损伤。照射组TGF-β1、TNF-α的mRNA及蛋白水平表达均高于对照组及中药组(P<0.05);除照射后1、24 h外, 治疗组TGF-β1、TNF-α在其余各时间点的表达水平均低于照射组(P<0.05)。结论 益气活血养阴解毒方具有抑制照射刺激下TGF-β1、TNF-α的表达、减轻放射性肺损伤的作用, 其机制与抑制TGF-β1、TNF-α的表达有关。

Abstract: Objective To investigate the influence of traditional Chinese medicine, Yiqihuoxue-Yangyinjiedu recipe, on transforming growth factor-β1(TGF-β1) and tumor necrosis factor-α(TNF-α) in lung tissues of mice with radiation-induced lung injury, and to explore the effects and action mechanism of Yiqihuoxue-Yangyinjiedu recipe on preventing and treating radiation-induced lung injury. Methods Mice were randomly divided into control group (n=21), drug group (n=21), radiation group (n=21), and treatment group (radiation+drug, n=21). The latter two groups were irradiated at whole thorax with a dose of 12 Gy. The pathology of radiation-induced lung injury was monitored. The expressions of TGF-β1 and TNF-α were analyzed by RT-qPCR and immunohistochemistry at 1, 24, 72 h and 2, 4, 8, 24 week post-irradiation. Results The results of histology demonstrated that Yiqihuoxue-Yangyinjiedu recipe treatment ameliorated radiation-induced lung injury. Expressions of TGF-β1, TNF-α mRNA and protein in radiation group were higher than those in control group and drug group (P<0.05). Except at 1 h and 24 h, expressions of TGF-β1 and TNF-α in treatment group at each time point were lower than those in radiation group (P<0.05). Conclusion Yiqihuoxue-Yangyinjiedu recipe can inhibit the expressions of TGF-β1 and TNF-α, and may play an important role in preventing and treating radiation-induced lung injury, which may be related to inhibit the expressions of TGF-β1 and TNF-α.
