Mol Med Rep:针灸通过TGF-β/ Smad通路减轻肾脏间质纤维化

2020-03-02 不详 网络

针灸是补充医学中最有用的工具之一,并已显示出治疗慢性肾衰竭(CRF)的潜在价值。然而,其治疗作用的潜在机制仍然未知。在本研究中,在CRF兔模型中探索了针刺对肾间质纤维化(RIF)的影响。将兔子分为以下五组:假手术,模型,氯沙坦钾(Posi),针灸(Acup)和针灸+抑制剂(Acup + Inhib)组。对CRF兔分别在Shenshu,Mingmen 和Pishu进行了药物或针刺治疗。测量兔子的体重

针灸是补充医学中最有用的工具之一,并已显示出治疗慢性肾衰竭(CRF)的潜在价值。然而,其治疗作用的潜在机制仍然未知。在本研究中,在CRF兔模型中探索了针刺对肾间质纤维化(RIF)的影响。

将兔子分为以下五组:假手术,模型,氯沙坦钾(Posi),针灸(Acup)和针灸+抑制剂(Acup + Inhib)组。对CRF兔分别在Shenshu,Mingmen 和Pishu进行了药物或针刺治疗。测量兔子的体重,尿蛋白,血清肌酐(SCr)和血尿素氮(BUN)水平。通过qRT-PCR检测转化生长因子β(TGF-β),整联蛋白连接激酶(ILK)和Smad3表达。使用western blot方法分析肿瘤坏死因子-α(TNF-α)和内皮型一氧化氮合酶(eNOS)的表达。使用ELISA试剂盒检测血清中TGF-β,IL-8,TNF-α和IL-1β的浓度。另外,通过H&E和Masson三色染色法评估了兔组织的病理学特征,并且通过免疫组织化学(IHC)测定法检测了TGF-β的表达。

结果显示,兔子体重减轻,尿蛋白,SCr和BUN水平升高,证实了CRF模型已成功构建。研究还发现,针灸可通过影响TGF-β/ Smad信号通路明显降低血清中TNF-α,Smad3,ILK和TGF-β的表达,显著降低血清中TGF-β,IL-8,TNF-α和IL-1β的浓度,并显著增加CRF模型兔中eNOS的表达。另外,已证明针灸可通过影响TGF-β/Smad通路减轻RIF。

总之,这些观察结果表明,针灸可用于治疗CRF,并提示TGF-β/Smad通路可作为CRF治疗的靶标。
