Abstract:
Objective To explore the mechanism ofHuanshuai Oral Liquid in the process of hypoxia-microvascular waste-renal interstitial fibrosis in mice with atherosclerosis renal artery stenosis.Methods The atherosclerosis renal artery stenosis model was established on Apoe-/- mice by high fat feed and uninephrectomy. After 2 weeks of renal ablation, model mice were randomly divided into TCM group (Huanshuai Oral Liquid) and model group. C57BL/6J mice were taken as the blank group. The mice of TCM group receivedHuanshuai Oral Liquid 0.01 mL/(g?d) for gavage, while the blank group and the model group received normal saline 0.01 mL/(g?d) for gavage. Renal function, atherosclerosis and renal interstitial fibrosis were assessed in the 12th week after taking medicine via immunohistochemical method to detect the expressions of the collagen typeⅣ, alpha smooth muscle actin (α-SMA) andⅧ factor related antigen (vWF), and via RT-PCR to detect the expressions of HIF-1α and TGF-β.ResultsCompared with the blank group, the model group suffered severe renal artery stenosis and renal fibrosis, and the expressions of HIF-1α, TGF-β, collagen typeⅣ andα-SMA significantly increased (P<0.05), while the expression of vWF decreased (P<0.05). Compared with the model group, the expressions of HIF-1α, TGF-β, collagen typeⅣ andα-SMA group, the expressions of HIF-1α, TGF-β, collagen typeⅣ andα-SMA significantly decreased in the TCM group (P<0.05), while the expression of vWF significantly increased (P<0.05).ConclusionHuanshuai Oral Liquid could significantly improve the renal function and the renal tubular-interstitial fibrosis. The mechanism might be associated with regulating the expressions of HIF-1α and TGF-β.
