前列消汤对大鼠前列腺增生的影响

目的:观察前列消汤治疗前列腺增生的疗效并初步探讨其作用机理。方法:采用丙酸睾酮致大鼠前列腺增生模型,进行随机对照分组研究,观察给药前后大鼠前列腺体积、前列腺指数、血清前列腺特异抗原(PSA)及性激素变化。结果:前列消汤可以明显抑制模型大鼠的前列腺增生,减小大鼠前列腺体积、湿重、前列腺指数,降低大鼠的睾酮(T)水平,提高大鼠的雌二醇(E2)、E2/T水平,降低大鼠血清PSA的表达。结论:前列消汤对丙酸睾酮所致前列腺增生有明显的抑制和治疗作用,其机制可能是通过调整体内性激素水平和比例,抑制前列腺细胞增殖;同时减低前列腺组织淤血,减少腺腔分泌物来实现的。

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.
