RESUMEN
Based on the SWOT analysis, this paper studied the advantages and disadvantages, external opportunities and challenges of foreign affairs work in Chongqing TCM Hospital. It also discusseds and presented the development strategy of hospital foreign affairs work. Chongqing Traditional Chinese Medicine Hospital developed its own advantages and reduces pressures by seizing external opportunities. It made use of external opportunities to overcome shortcomings, solve internal problems, and respond to external challenges. The hospital gradually regulates the foreign affairs work, enhances the international communication capability of TCM, and expands the influence and core competitiveness.
RESUMEN
OBJECTIVE:To optimize the ethanol extraction process of anti-atherosclerosis effective fraction of Lindley eupatorium. METHODS:Using the contents of hyperin,quercetin,kaempferol and jaceosidin as indexes,the effects of ethanol volume fraction,liquid-solid ratio,extraction time and extraction times on ethanol extraction technology were investigated. By multiple index scoring method,orthogonal test was designed to optimize extraction technology,and validation test was conducted. RESULTS:The optimal extraction technology was 70% ethanol as extraction solvent with solid-liquid ratio of 12 : 1,reflux extracting for 3 times,2 h each time. Results of 3 batches of validation tests showed that the contents of 4 marker components were in high level,being 5.305 3,1.560 1,1.986 5,6.703 6 mg/g in average(RSD<1.1%,n=3). Results of validation tests were stable and reliable,and were in good agreement with the results of orthogonal tests. CONCLUSIONS:The optimized ethanol reflux extraction technology of L. eupatorium is stable and reliable,and performs well. Energy consumption and cost are suitable for industrial production.The results provide technology basis for further purification and enrichment of anti-atherosclerosis effective components of L.eupatorium.
RESUMEN
OBJECTIVE:To establish a method for the content determination of sinomenine in Qihuang capsule. METHODS:HPLC was performed on the column of welch C18-AQ with mobile phase of methanol-phosphate buffer(gradient elution) at flow rate of 1.0 ml/min,detection wavelength was 264 nm,column temperature was 30 ℃ and volume injection was 10 μl. RESULTS:The linear range of sinomenine was 0.200 3-10.016 0 μg(r=0.999 8),RSDs of precision,stability and reproducibility tests were lower than 1.0%,recovery was 98.80%-100.94%(RSD=0.79%,n=6). CONCLUSIONS:The method is simple,accurate and re-producible,and can be used for the content determination of sinomenine in Qihuang capsule.
RESUMEN
This article was aimed to study the latest research progress of Tripterygium hypoglaucum, in order to pro-vide references for further research on T. hypoglaucum. CNKI Chinese Journal Full-text Database was used as data source. Bibliometric analysis was conducted on T. hypoglaucum research articles issued from 1915~2013. Bibliometric method was used in the analysis on the change trend among years, research institutes, publication dates, research per-sonnels and research topics of the articles with the built-in analysis tools and network analysis tools. The results indi-cated that T. hypoglaucum research was still in the development stage. And there is still plenty of room for growth in aspects including resources, material basis, manufacturing pharmacy and so on.
