The results showed that EFT could increase phagocytosis activity of macrophagocyte (P<0 05), promote lymphocyte transformation rate (P<0 01), increased the sero antibody level meanly (P<0 05), low dosage group could increased Plaque Forming Cell (PFC) signficantly (P<0 05), raise the ratio of spleen to body (P<0 05) of EAC bearing mice. EFT may be enhance burdened mice’s immunofunction. Low dosage can improve sero antibody level. Effect on regulating cellular immunofunction are related to dosage. EFT may be inhibit the growth of EAC cells to some degree.展开更多

Methods: In this study, the network pharmacology and bioinformatics technology were used to explore the mechanism of "Epimedium - Cistanche deserticola" in the treatment of breast cancer bone metastasis. TCMSP, TCM database@Taiwan and TCMID databases were used to screen the main effective components of the drug. Swiss Target Prediction and STITCH databases were used to search the potential target of action of Epimedium and Cistanche deserticola. Genecards, OMIN and Drugbank databases were used to search the cause of bone metastasis of breast cancer. The target of action of the drug and the disease gene were mapped for GO and KEGG signal pathway analysis, A visualized network of "drug - component - target - signaling pathway" was constructed by using the software of Cytoscape 3.6.0, and the core genes were screened out. Results: The study found that there are 30 main effective components of Epimedium and Cistanche deserticola, and 544 genes are involved in the potential therapeutic targets, among which 101 genes are potential targets of Epimedium and Cistanche deserticola in the treatment of breast cancer bone metastasis. Through the analysis of GO and KEGG pathways, we found that the mechanisms involved in antitumor, osteoblast differentiation, osteoclast apoptosis and regulation of bone microenvironment, such as apoptosis, osteoclast differentiation, PI3K-Akt, HIF-1 signaling pathway, T cell receptor signaling pathway, etc. TP53, VEGFA, AKT1, EGFR, SRC, CCND1, MAPK3, ESR1 may be the key genes in the treatment of breast cancer bone metastasis. Conclusion: In this study, the network of "drug - component - target- signaling pathway" was constructed through network pharmacology, and it was found that the mechanism of "Epimedium - Cistanche deserticola" in the treatment of breast cancer bone metastasis involves multiple targets and pathways, which is conducive to guiding clinical medication.展开更多

By examining pressure, temperature, amounts of modifier and extraction time, the optimized condition of SFE is confirmed as 30 MPa and 60 ℃, with 70% ethanol as the modifier. The samples were statically extracted for 30 min, followed by dynamic extraction for 120 min at a flow rate of 6 mL/min. The quantitative analysis of total flavonoids was performed by UV-Vis spectrophotometry. Compared with the conventional method, the SFE method is more efficient, more rapid and more friendly environmentally.展开更多

The images of the surface structures showed clear concave and progressive increase of surface roughness of erythrocyte after incubation with EE at concentration of 0.2 or 0.05 g/L, far below its critical hemolytic levels. The AFM results also indicated that the granules of the fine surface structure increased, which caused by aggregation of membrane protein. Further study showed that the change in surface topography of erythrocyte membrane might be connected with the increase of intracellular free Ca2+ induced by EE.展开更多
