①目的探讨大肠癌组织中p53及nm23的表达与浸润转移的关系。②方法应用免疫组织化学LSAB法检测75例大肠癌中p53及nm23的表达。③结果大肠癌组织中p53,nm23的阳性率分别为53.3%和65.3%.p53过表达和nm23低表达均与大肠癌的浸润深度及淋巴结转移有关。p53在低分化癌中的表达明显高于高分化癌(χ2=10.08,P<0.01),而nm23表达与大肠癌分化程度无关(χ2=3.39,P>0.05)。④结论p53高表达和nm23低表达在大肠癌的浸润转移中起重要作用,大肠癌淋巴结转移可能与多基因异常有关  相似文献

应用免疫组化SABC法检测49 例食管鳞癌、12 例食管腺癌和20 例食管正常组织。结果显示,28 例食管鳞癌(57.1% ,28/49)4 例食管腺癌(33.3% ,4/12)和18 例食管正常组织(90% ,18/20)p16 蛋白表达阳性(P< 0.01),伴有淋巴结转移的食管鳞癌p16 蛋白表达阳性率(39.3% )显著低于无淋巴结转移者(81.0% ,P< 0.01),中低分化食管癌p16 蛋白表达阳性率(46.9% )低于高分化者(76.5% ,P< 0.05)。Ⅲ期食管癌p16 蛋白表达阳性率(44.4% )亦低于Ⅱ期者(72.7% ,P< 0.05)。p16 蛋白表达与肿瘤的大体病理类型无关。p16 蛋白在食管癌中呈低表达,其表达阳性率随病期进展、淋巴结转移、细胞分化程度降低而明显降低,因此,可作为判断食管肿瘤恶性度和预后的指标  相似文献

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.  相似文献

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.  相似文献
