• Network pharmacology method was performed to analyze the mechanisms of BuYangHuanWu decoction on atherosclerosis. • Cytokines including IL1β, TGFB1, TNF-α, IL-6 are proved to be key pharmacological targets. • AS animal model was bulit and BuYangHuanWu decoction was determined to be effective in treating atherosclerosis. • NF-κB signaling pathway was blocked by BYHWD. Atherosclerosis (AS) is one of the leading causes of cardiovascular disease and has a high rate of morbidity and mortality. Traditional Chinese Medicine (TCM) supplied many therapies for AS treatment for centuries. Among these treatments, BuYangHuanWu decoction (BYHWD) is a classic prescription. In this study, we analyzed the mechanisms of BYHWD in the treatment of AS by using a network pharmacology method. Our results revealed the mechanisms of BYHWD in treating AS, which is highly related to inflammation and apoptosis pathways, moreover, the genes including IL1β, TGFB1, TNF, IL6, NFκB1 are proved to be the key pharmacological targets for the treatment of AS. Furthermore, an AS rat model was established and the rats in the treatment group received different amounts of BYHWD. Serum lipid levels (TC/TG/HDL-C/LDL-C) and tissue oxidative stress levels (SOD, GSH-Px, CAT and MDA) were ameliorated in a dose-dependent manner. The morphology of the aortic intima in the BYHWD -treated groups was improved. Real-time PCR and Western blot analysis results indicated that inflammatory cytokines were suppressed and that the NF-κB signaling pathway was blocked by BYHWD. All of this evidence suggested that BYHWD is an ideal prescription for treating AS. [ABSTRACT FROM AUTHOR]

We aim to investigate the effects of adipose-derived stem cells (ASCs) transplantation on irradiation-induced skeletal muscle fibrosis. Sixty-four rabbits were randomly divided into ASCs group and PBS group followed by irradiation at unilateral hip with a single dose of 80 Gy. Nonirradiated side with normal skeletal muscle served as normal control. Skeletal muscle tissues were collected from eight rabbits in each group at 1 w, 4 w, 8 w, and 26 w after irradiation. Migration of ASCs was observed in the peripheral tissues along the needle passage in the injured muscle. The proportion of the area of collagen fibers to the total area in sections of ASCs group was lower than those of PBS groups at 4 w, 8 w, and 26 w after irradiation. Significant decrease was noted in the integrated optimal density of the transforming growth factor β1 (TGF-β1) in the ASCs group compared with those of PBS group at 4 w, 8 w, and 26 w after irradiation. Moreover, the expression of TGF-β1 was lower in the ASCs group compared to those of the PBS group at each time point determined by Western blot analysis. ASCs transplantation could alleviate irradiation fibrosis by suppressing the level of TGF-β1 in the irradiated skeletal muscle. [ABSTRACT FROM AUTHOR]
