RESUMEN
OBJECTIVE:To promote the healthy development of TCM decoction piece. METHODS:Based on analyzing the literature,national policy and data,the advantages and urgent problems of bringing TCM decoction piece into the National Essen-tial Medicine List were summarized,and the suggestions for its health development were provided. RESULTS:Bringing TCM de-coction piece into the National Essential Medicine List relieved the economic burden of patients and provided opportunity for the de-velopment of TCM decoction piece industry. However,it existed problems,such as production,circulation,storage and monitor-ing;mutual conflict in the relevant supporting policies;inconsistent medicare reimbursement;and urgent improvement of quality standard. CONCLUSIONS:The relevant departments should establish and improve the quality standard system of TCM decoction piece,and clear the varieties of TCM decoction piece in the National Essential Medicine List,perfecting supporting policies such as medicare reimbursement and attaching importance to the training of professional talents can ensure scientific and rational services for the public health.
RESUMEN
[ ABSTRACT] AIM:To investigate the effect of DEK downregulation on the apoptosis of gastric carcinoma SGC-7901 cells, and to explore its associations with NF-κB signaling pathway and apoptosis related proteins.METHODS:SGC-7901 cells with different treatments were divided into 3 groups including untreated group, control siRNA group and DEK siRNA group.The expression of DEK at mRNA and protein levels in the SGC-7901 cells was detected by real-time PCR and Western blot.The cell apoptosis was examined by flow cytometry.Furthermore, the activities of caspase-3 and caspase-9 in the SGC-7901 cells were investigated by Caspase-Glo?-3/9 kit.Finally, the expression of key regulatory pro-tein p65 of NF-κB signaling pathway and apoptosis-related proteins Bcl-2 and Bax in the SGC-7901 cells was investigated by Western blot.RESULTS:Compared with untreated group and control siRNA group, the expression of DEK at mRNA and protein levels was significantly downregulated in DEK siRNA group (P<0.05).In addition, the ratios of early phase apoptosis and total apoptosis in DEK siRNA group were markedly higher than those in untreated group and control siRNA group (P<0.05).Most notably, the decrease in p65 and Bcl-2 proteins, increase in Bax protein and the increases of caspase-3 and caspase-9 activities were observed in DEK siRNA group.CONCLUSION:Downregulation of DEK mediates cell apoptosis of gastric carcinoma may be tightly associated with NF-κB signaling pathway.
RESUMEN
Tepoxalin is a potent inhibitor of both the cyclooxygenase and lipoxygenase pathways of the arachidonic acid cascade, as well as a potent anti-inflammatory and control-pain (postoperation, arthritis et. al.) agent. The new method about the use of novel synthesis reagents and the first using ionic liquid as reactive solvent to synthesize tepoxalin were presented in this paper. The ionic liquid can be easily recycled and reused for several runs efficiently. The analgesic activity of tepoxalin was detected by acetic acid test on mice. The analysis of variance showed that oral administration of tepoxalin could significantly inhibit the number of writhing response within 1 hour and prolong the latent time in a dose dependent manner as compared with CMC control group (P < 0.05). At the same time, tepoxalin had the same analgesic activity as diclofenac sodium.
