The present studies explored the effects of Danggui Buxue Tang (DBT) that is a Chinese medicinal de- coction on negative charge to Human Umbilical Vein Endothelial Cell (HUVEC) and the related mechanism. Alcian blue staining was established to evaluate the intensity of negative charge on HUVEC. Proteoglycan expressions of AGP and avidin were determined by SDS-PAGE. We observed that DBT can significantly increase negative charge on HU-VEC and up-regulated AGP and avidin expressions and ameliorate AGEs-induced HUVEC apoptosis. Therefore, all results showed DBT had prevention effects against the progression of AGEs-induced damage, and this decoction might be promising agent against proteinuria in diabetic nephropathy.展开更多

Exploring new ways of treatment with DBT is useful. Sprague–Dawley(SD) rats were randomly divided into 3 groups including control(NC, Saline), the DBT(at a dose of 8.10 g?kg–1), and blood deficiency(BD)(Cyclophosphamide(APH)-and Cyclophosphamide(CTX)-induced anaemia). A metabolomics approach using Liquid Chromatography-Quadrupole-Time-of-Flight/Mass Spectrometry(LC/Q-TOFMS) was developed to perform the plasma metabolic profiling analysis and differential metabolites were screened according to the multivariate statistical analysis comparing the NC and BD groups, and the hub metabolites were outliers with high scores of the centrality indices. Anaemia disease-related protein target and compound of DBT databases were constructed. The TCMSP, Chem Mapper and STITCH databases were used to predict the protein targets of DBT. Using the Cytoscape 3.2.1 to establish a phytochemical component–target protein interaction network and establish a component, protein and hub metabolite protein–protein interaction(PPI) network and merging the three PPI networks basing on BisoGenet. The gene enrichment analysis was used to analyse the relationship between proteins based on the relevant genetic similarity by ClueGO. The results shown DBT effectively treated anaemia in vivo. 11 metabolic pathways are involved in the therapeutic effect of DBT in vivo; S-adenosyl-L-methionine, glycine, L-cysteine, arachidonic acid(AA) and phosphatidylcholine(PC) were screened as hub metabolites in APH-and CTX-induced anaemia. A total of 288 targets were identified as major candidates for anaemia progression. The gene-set enrichment analysis revealed that the targets are involved in iron ion binding, haemopoiesis, reactive oxygen species production, inflammation and apoptosis. The results also showed that these targets were associated with iron ion binding, haemopoiesis, ROS production, apoptosis, inflammation and related signalling pathways. DBT can promote iron ion binding and haemopoiesis activities, restrain inflammation, production of reactive oxygen, block apoptosis, and contribute significantly to the DBT treat anaemia.展开更多

Pulmonary fibrosis rat model was established by intratracheal injection with bleomycin. Body weight and lung index were monitored. Histopathologic examination and collagen deposition were determined using Hematoxylin and eosin(HE) and Masson's trichrome staining. Immunohistochemistry staining was applied to observe the expression of alpha-smooth muscle actin(α-SMA). m RNA expression of α-SMA,collagen Ⅰ and collagen Ⅲ were measured by realtime fluorescence quantitative PCR(RT-q PCR). Inflammatory cytokines, including tumor necrosis factor alpha(TNF-α), interleukin-6(IL-6) and IL-1β in serum were detected by Enzyme-linked immunosorbent assay. Alkali hydrolysis method was conducted to investigate the content of hydroxyproline(HYP). Transforming growth factor-β1(TGF-β1),Smad3 and plasminogen activator inhibitor-1(PAI-1) protein level were examined by Western blot assay.RESULTS: DBT significantly reduced the severity of bleomycin-induced pulmonary fibrosis and inflammation as indicated by minimizing the lost of weight, and by lowering the levels of lung index, inflammation score, Ashcroft score, collagen volume fraction(%), HYP, α-SMA, collagen Ⅰ, collagen Ⅲ,TNF-α, IL-6, IL-1β, TGF-β1, Smad3 and PAI-1, consistent with the effect of prednisone.CONCLUSION: Our findings suggest that DBT is able to ameliorate the pulmonary fibrosis, the possible mechanism may involve inhibition of pulmonary inflammation and collagen deposition, possibly via suppressing TGF-β1/Smad3/PAI-1 signaling pathway.展开更多
