刺梨汁及其复方抗衰老的药效实验研究

用小鼠荷重游泳试验作抗疲劳指标，用高脂饲料喂养小鼠以形成高脂血症模型，研究了刺梨汁及其及方的抗疲劳和降血清胆固醇的作用，并用碳粒廓清试验检测了刺梨汁对正常小鼠及免疫抑制小鼠非特异性免疫功能的影响，结果表明：刺梨汁及其复方均有明显的抗疲劳（Ｐ＜０．０１）和降低血清胆固醇的作用（ｐ＜０．０５），并能提高免疫抑制小鼠的免疫器官重量，而对小鼠的巨噬细胞吞噬功能无明显影响。     

刺梨汁对小鼠耐缺氧、耐疲劳的影响

本文初步探讨了刺梨汁对纯系BALB/C小鼠耐缺氧、耐疲劳作用的影响。结果表明,服用刺梨汁的小鼠,在缺氧环境中的生活时间较长,机体耗氧率较低,在水中泳动的时间也明显长于对照组。提示刺梨汁在一定程度上有提高机体耐缺氧、耐疲劳能力的作用。通过与所设的V-C对照组比较,认为刺梨汁的这些作用并非是所富含的V-C的功劳,而可能是刺梨汁中多种营养成分共同作用的结果。     

生川乌配伍全瓜蒌对小鼠急性毒性的影响

目的:观察生川乌与全瓜蒌配伍对小鼠急性毒性的影响。方法:140只昆明小鼠随机分为生川乌单行(RA)及生川乌配伍全瓜蒌水浸剂(RAFT)组,每组70只。每组再随机分为6个给药组及空白对照组,每组10只。各给药组小鼠分别灌胃给予不同剂量的受试药物(以乌头剂量计算):4.7g/kg、6.7g/kg、9.6g/kg、13.7g/kg、19.6g/kg和28.0g/kg。给药后观察14d,记录小鼠的中毒潜伏期、症状及死亡时间、恢复期及死亡数量,用改进寇氏公式计算LD50。结果:生川乌与全瓜蒌配伍后中毒潜伏期、死亡时间较单行相应剂量组缩短,中毒恢复期延长(P0.05)。生川乌单行LD50为9.26g/kg,95%可信限为7.70g/kg-1.15g/kg;生川乌配伍全瓜蒌LD50为7.48g/kg,95%可信限为6.40g/kg-8.74g/kg。结论:生川乌配伍全瓜蒌对小鼠的急性毒性强于生川乌单行。

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.
