Chronic kidney disease (CKD) is becoming a worldwide problem. However, current treatment options are limited. In the current study we showed that QiShenYiQi (QSYQ), a water-ethanol extract from several Chinese medicines, is a potent inhibitor of renal interstitial fibrosis. QSYQ inhibited transforming growth factor-β1 (TGF-β1)-responsive α-smooth muscle actin (α-SMA), collagen I, and fibronectin up-regulation in obstructive nephropathy and cultured cells. Administration of QSYQ also inhibited the established renal interstitial fibrosis in obstructive nephropathy. Interestingly, QSYQ selectively inhibited TGF-β1-induced β-catenin up-regulation and downstream gene transcription. Taken together, our study suggests that QSYQ selectively inhibits TGF-β1-induced β-catenin up-regulation and might have significant therapeutic potential for the treatment of renal fibrosis.
慢性肾脏病（CKD）正成为一个全球性问题。然而，目前的治疗选择有限。在本研究中，我们表明，芪参益气（QSYQ），一种从多种中药中提取的水-乙醇提取物，是肾间质纤维化的有效抑制剂。QSYQ抑制梗阻性肾病和培养细胞中转化生长因子-β1（TGF-β1）反应性α-平滑肌肌动蛋白（α-SMA）、I型胶原和纤连蛋白的上调。给予QSYQ还可抑制梗阻性肾病中已形成的肾间质纤维化。有趣的是，QSYQ选择性抑制TGF-β1诱导的β-连环蛋白上调和下游基因转录。综上所述，我们的研究表明，QSYQ选择性抑制TGF-β1诱导的β-连环蛋白上调，可能对肾纤维化治疗具有显著的治疗潜力。
