Objective:We aimed to evaluate the feasibility and effectiveness of postoperative 125I brachytherapy delivered by use of digital model obturators for recurrent or locally advanced maxillary cancers.Materials and Methods:From 2006 to 2008,12 patients(7 females; median age 65 years [range 22-86 years])with recurrent or locally advanced maxillary cancers showing positive margins after surgery underwent 125I brachytherapy by use of digital model obturators and interstitial implants.The radioactivity was 18.5-33.3 MBq per seed and the prescription dose 80-160 Gy.Functional outcome of patients was evaluated by the Performance Status Scale(PSS)for head and neck cancer before and after brachytherapy.

目的:采取回顾性研究的方法,分析彩超引导下细针穿刺活检是否可提高颈部肿物诊断的准确率,并探讨其在颈部肿物诊断及鉴别诊断中临床应用价值.方法:对97例颈部肿物患者行彩超检查,必要时行CT及MRI检查.颈部肿物定位明确后,54例患者行彩超声引导下的细针穿刺活检(实验组),另43例患者采用触诊法行细针穿刺活检(对照组),97例患者的穿刺活检结果均与手术结果进行比较分析.结果:实验组标本的取材成功率为95
目的:探讨DEK基因沉默对人头颈鳞癌细胞活性的影响.方法:将DEK-SiRNA转入人头颈鳞癌细胞PCI-37B,采用噻唑蓝比色(MTT)和流式细胞仪分别检测细胞增殖,细胞凋亡和细胞周期的改变情况.结果:DEK基因沉默能够使人头颈鳞癌细胞的增殖抑制率和凋亡率均显著增高(P＜0.01),同时,抑制DEK基因能够干扰细胞周期,使细胞G1期比例显著上升(P＜0.01).结论:DEK基因抑制能够诱导人头颈鳞
