目的研究EFNA3在结直肠癌中的表达及关系。方法随机选取湘南学院附属医院84例结直肠病例,分结直肠癌、结直肠良性肿瘤和正常结直肠组织3组,采用免疫组织化学方法分别检测3组中EFNA3的表达情况。结果EFNA3在结直肠癌组中的表达强度为3.6&...目的研究EFNA3在结直肠癌中的表达及关系。方法随机选取湘南学院附属医院84例结直肠病例,分结直肠癌、结直肠良性肿瘤和正常结直肠组织3组,采用免疫组织化学方法分别检测3组中EFNA3的表达情况。结果EFNA3在结直肠癌组中的表达强度为3.6±1.3,相比良性结直肠肿瘤组(5.1±0.6)和正常结直肠组(4.9±1.3)较低(P<0.05)。高分化组EFNA3表达量高于低分化组(4.2±0.4 vs 3.3±1.6,P<0.05);有淋巴结转移组肿瘤组织中EFNA3的表达量低于无淋巴结转移组(3.3±1.7 vs 4.13±0.28,P<0.05);TNM分期Ⅲ+Ⅳ者肿瘤组织中EFNA3表达量低于Ⅰ+Ⅱ者(3.3±1.7 vs 4.13±0.28,P<0.05)。结论EFNA3随着癌症发生过程的逐渐深入而表达递减,表明可能与结直肠癌的发生过程有关并在其中起到了类似抑癌基因的作用。展开更多

The purpose of this prospective study was to assess the detection sensitivity of colorectal neoplasms with the three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography with air enema. Methods A total of 30 patients scheduled for optical colonoscopy due to rectal bleeding, positive fecal occult blood test results or altered bowel habits were recruited and successfully underwent entire colorectal examinations with three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography and subsequent optical colonoscopy on the same day. Detection sensitivity of colorectal neoplasms with MR colonography was statistically analyzed on a per-neoplasm size basis by using findings from optical colonoscopy and histopathological examinations as the reference standards. Results Seventy-six neoplasms were detected with optical colonoscopy, consisting of 1 mm-5 mm （n=11）, 6 mm-9 mm （n=29） and 〉10 mm （n=-36） in diameter. Detection sensitivities of 1 mm-5 mm, 6 mm-9 mm, 〉10 mm and 〉6 mm colorectal neoplasms with MR colonography were 9.1%, 75.9%, 100% and 89.2%, respectively; overall detection sensitivity for all sizes colorectal neoplasms was 77.6%. Conclusions Detection sensitivity of three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography with air enema is low for 1 mm-5 mm colorectal neoplasms, but the detection sensitivity is 89.2% for ≥6 mm neoplasms, and all ≥10 mm neoplasms could be detected.展开更多
