川续断皂苷Ⅵ通过JNK信号通路促进骨髓间充质干细胞成骨分化

【目的】探讨川续断皂苷Ⅵ诱导大鼠骨髓间充质干细胞(BMSCs)向成骨细胞方向分化的机制。【方法】全骨髓贴壁法培养大鼠BMSCs。实验分为诱导组,1μmol/L川续断皂苷Ⅵ组,1μmol/L川续断皂苷Ⅵ+5μmol/L SP抑制组,1μmol/L川续断皂苷Ⅵ+10μmol/L SP抑制组,1μmol/L川续断皂苷Ⅵ+20μmol/L SP抑制组等5组。采用茜素红染色和骨钙素定量法检测细胞成骨分化程度;采用碱性磷酸酶(ALP)染色测定ALP活性;采用生物信息学方法预测c-Jun氨基末端激酶(JNK)相关因子。【结果】与诱导组比较,1μmol/L续断皂苷Ⅵ组茜素红染色明显增加,ALP活性增强,骨钙素表达量增加(P0.05)。与1μmol/L川续断皂苷Ⅵ组比较,1μmol/L川续断皂苷Ⅵ+5μmol/L SP抑制组、1μmol/L川续断皂苷Ⅵ+10μmol/L SP抑制组、1μmol/L川续断皂苷Ⅵ+20μmol/L SP抑制组茜素红染色程度降低,ALP活性减弱,骨钙素含量显著减少(P0.05)。生物信息学表明c-Jun和转录激活因子4(ATF4)、骨形态发生蛋白2(BMP2)之间存在直接的相互联系。【结论】川续断皂苷Ⅵ诱导BMSCs成骨分化的机制可能与JNK信号通路的激活有关。

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.
