核因子κB及其SUMO化调控与糖尿病肺改变

核因子κB(NF-κB)是一种广泛存在于机体各种细胞中的核转录因子,受到外界刺激时可被激活进入细胞核参与炎性反应。小泛素相关修饰物(SUMO)广泛存在于真核细胞中,包括SUMO1、SUMO2、SUMO3和SUMO4 4个成员。SUMO可以与靶蛋白(如IκB)结合,对其进行SUMO化修饰,间接调控NF-κB转录。近年来研究发现,NF-κB在糖尿病及其并发症的发生、发展中起着重要作用。现就NF-κB的结构,信号通路及其调控以及与糖尿病肺脏改变的关系进行综述。

核因子κB在严重创伤中的作用

核因子κB（nuclear factor kappa B,NF-κB）是真核细胞的核转录因子。1986年Sen和Baltimore首先发现它是B淋巴细胞中免疫球蛋白kappa轻链转录所需要的转录因子,故命名为NF-κB。后发现NF-κB不仅存在于B淋巴细胞,而且普遍存在于真核细胞。NF-κB受多种刺激因素激活后入核内,能和许多基因启动子区域的固定核苷酸序列结合,启动基因转录发挥其转录调节因子的功能,在机体免疫应答、炎症反应及细胞的生长调控等方面发挥信号转导枢纽的作用。目前,对NF-κB在严重创伤中作用的研究已进入一个新的领域。

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.
