化橘红原植物化州柚生长过程中黄酮类成分的变化规律研究

【目的】观测化橘红来源植物化州柚在生长过程中黄酮类等成分含量的动态变化规律,为确立采收化橘红时机提供依据。【方法】分别采用分光光度法、高效液相色谱法测定化州柚果皮和叶中总黄酮及柚皮苷含量,并制备指纹图谱。【结果】随着果龄的增加,化州柚果皮和叶中柚皮苷及总黄酮含量均呈显著性下降趋势;但指纹图谱显示,成果初期果皮中野漆树苷含量随果龄的增加而显著升高,62 d后才显著下降,叶中野漆树苷含量则无显著性变化。【结论】从经济价值和有效成分含量两方面综合考虑,果龄34 d时采收化州柚幼果,果龄55 d时采收化州柚未成熟果较为合适。

不同产地、炮制方法、采收时间的芍药中有效成分含量差异研究进展

[目的]综述不同来源芍药中有效成分含量差异的研究进展。[方法]通过总结近10年的相关文献,比较浙江、安徽、河北、山东等地芍药,酒制、炒制、硫磺熏蒸等炮制方法,不同季节和生长年限采收的芍药,以及芍药根的不同部位,从不同产地、炮制方法、采收时间等方面阐明芍药中有效成分的含量差异。[结果]不同产地的芍药中芍药苷和芍药内酯苷含量差异明显。磐安、亳州等地的芍药中芍药苷和芍药内酯苷的含量较高。河北产的野生芍药,其芍药苷含量明显高于其他产地,而芍药内酯苷的含量并不高。其他成分的含量在不同产地芍药中的分布各有不同。不同炮制方法会导致芍药中有效成分的含量和种类发生变化,短时间的煎煮可有效提高芍药苷和芍药内酯苷的含量,酒制和炒制会降低芍药苷的含量,硫磺熏蒸则会促使芍药苷转变成芍药苷的磺酸盐,其他成分的含量也有不同程度的减少。与夏季相比,芍药更适合在春秋季采收,且合适的采收时间是在第二次生长之后。根皮可对化学成分的转化和流失起到一定的保护作用。[结论]磐安、亳州等地的芍药中芍药苷和芍药内酯苷含量较高,炮制会使芍药中其他有效成分产生不同程度的减少或转化,合适的采收时间应当在第二次生长之后。对儿茶素、没食子酸等含量的研究相对较少,因此对这些成分的含量差异还有待进一步研究。

Survey and practice of reporting quality of randomized controlled clinical trials on traditional Chinese medicine

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.     

TCM Treatment of Ankylosing Spondylitis by Tonifying the Kidney and Strengthening the Governor Vessel

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.
