西南獐牙菜(Swertia cincta Burkill.)为龙胆科獐牙菜属植物,我省分布广泛,资源较丰富,民间用治肝炎。其同科同属植物青叶胆(Swertia yunnanensis Burk)及川西獐牙菜(Swertia mussotii Franch)国内已有研究,前者对实验性肝炎,后者对低张性低氧肝损伤均有保护及防治作用。这两种植物的有效成分主要为齐墩果酸(Oleanolic acid)、芒果甙(mangiferin)及(口山)酮(Xanthone)。齐墩果酸有降低转氨酶的作用。目前国内已生产并用于临床。西南獐牙菜经我院植化组研究、证明含齐墩果酸及(口山)酮,但其药理研究尚未见报道。本研究拟初步观察其对动物实验性  相似文献

Evidence obtained from randomized controlled trials (RCTs) has been generally accepted as the gold standard in the evaluation of clinical effectiveness. Readers need to understand the trial design, implementation, results, analysis and interpretation, so as to fully Jnderstand the results of RCTs. Thus, the investigators of RCTs have to report these items in a complete, accurate and clear manner. Since 1998, we have conducted several evaluations on the reporting quality of RCTs published in Chinese journals on traditional Chinese medicine (TCM) and results have shown that there is an urgent need for higher quality RCTs on TCM.  相似文献

Ankylosing spondylitis is a chronic and progressive disorder with inflammation mainly involving the central axis joints. It mainly affects the cervical spine and the lumbosacral area, with the pathogenesis closely related to the kidney and the Governor Vessel (GV). TCM holds that the syndrome is deficiency in origin and excess in superficiality, which is due to insufficiency of the kidney, deficiency of GV, and blocking of the channels with the invasion of exogenous evil, leading to poor circulation of qi and blood and malnutrition of the bones, muscles and joints. The TCM method of tonifying the kidney and strengthening GV to regulate circulation of qi and blood and check the arthralgia pain should be adopted, with the Kidney-Tonifying and GV Strengthening Decoction (益肾强督汤) prescribed.  相似文献
