RESUMEN

Aim To explore the effect of a combination of Astragalus, Epimedium and Pueraria on the expression of hepcidin in hippocampal CA3 region of APPswe/PSldE9 double transgenic AD model mice. Methods Thirty 10-month-old APPswe/PSldE9 double transgenic model mice were randomly divided into three groups; the compound group, the model group and the deferox (D F X) group, and ten 10-month-old C57BL/6J mice were as normal control group. Subsequently, the brain tissue of the mice was taken out, and the expression of hepcidin in the hippocampal CA3 region of each group of mice was detected by immunofluorescence combined with Real-time PCR and Western blot. Results Compared withnormal group, the mRNA expression of hepcidin was down-regulated inmodel group. Afterintragastric administrationof active components of Epimedium, Astragalus and Radix Puerariae and DFX, hepcidin expression levels increased significantly compared with those in APPswe/PSldE9 double transgenic AD model mice hippocampal CA3 area (P 0. 05). Conclusions The effective components of Astragalus, Epimedium and Radix Puerariae can up-regulate the expression of hepcidin, It is suggested that the effective components of Epimedium, Astragalus, and Radix Puerariae have important theoretical significance in the clinical treatment of Alzheimer's disease with iron overload.

RESUMEN

Hepatic fibrosis is a liver damage healing response affected by a variety of factors; its formation is associated with multiple cytokines and a variety of signaling pathways. Transforming growth factor beta1( TGF-β1) is one of the strongest fibrosis cytokines known,and involves almost all the key links in hepatic fibrosis. TGF-β1/Smads signal pathway is the most classical pathway for TGF-β1 to play its role in promoting fibrosis as well as one of the most important signaling pathways of hepatic fibrosis formation. Studies for the signal pathway have made a series of scientific research achievements in recently years. Traditional Chinese medicine has the advantages of " multiple ingredients,multiple targets and less side effects",and is widely used in the clinical treatment of hepatic fibrosis.Effective components of traditional Chinese medicine are monomer compounds,which are extracted and purified from traditional Chinese medicine. Nowadays,the molecular biology studies of effective traditional Chinese medicine have become a hotspot. Modern advanced technology and methods can be used to directly clarify the targets and the signaling pathways,reveal the mechanism of traditional Chinese medicine in treating diseases,and promote the modernization and international development of traditional Chinese medicine industry. This review summarized the structure,function and application of TGF-β1/Smads signaling pathway in the progress of anti-hepatic fibrosis,and analyzed the action mode and possible mechanism of various effective components of traditional Chinese medicine in regulating TGF-β1/Smads signaling pathway and intervening the treatment of hepatic fibrosis in the past five years,so as to put forward new ideas for innovating new targeted traditional Chinese medicine for hepatic fibrosis.
