简介:目的分析原发性眼眶肿瘤的组织来源、手术进路及手术效果。方法回顾性分析5年开眶手术治疗的眼眶肿瘤101例。结果前十位的眼眶肿瘤分别是:海绵状血管瘤22例(21.78%),静脉性血管瘤10例(9.9%),(表)皮样囊肿泪腺10例(9.9%),泪腺混合瘤8例(7.92%),炎性假瘤7例(6.93%),脑膜瘤6例(5.94%),腺样囊性癌5例(4.95%),淋巴瘤4例(3.96%),肉瘤3例(2.97%),神经鞘瘤2例(1.98%)。手术方法包括前路入眶68例,外侧开眶27例,眶内容6例,术后复发4例。结论开眶手术的术式选择与肿瘤的性质、位置、粘连情况、病变范围密切相关。术前对肿瘤的性质、位置、粘连程度的正确判断和手术操作技巧可减少术后复发等并发症。术后复发病例主要为脑膜瘤及泪腺肿瘤。
简介:目的观察上调白细胞介素10(IL-10)的表达对家兔慢性细菌性鼻窦炎动物模型上颌窦黏膜创伤修复的影响。方法以慢病毒(LV)为表达载体,上调IL-10的表达(LV-IL-10)。实验分3组:生理盐水注射组、LV-IL-10治疗组和LV-GFP注射组(GFP为绿色荧光蛋白)。制作家兔慢性细菌性鼻窦炎模型。在创伤前3d,各组上颌窦内侧壁黏膜下分别注射生理盐水、LV-IL-10和LV-GFP。于创伤后第3天和第10天取再生的上颌窦内侧壁黏膜,用实时聚合酶链反应和酶联免疫吸附试验分别在mRNA水平和蛋白水平检测相关细胞因子的表达。苏木素-伊红(HE)染色和Masson三染色法观察创伤后第10天再生黏膜的形态特征。结果在创伤后第3天和第10天再生的上颌窦黏膜中,LV-IL-10治疗组的胶原沉积明显减少,炎症反应较轻,且IL-6以及Ⅰ型和Ⅲ型胶原的mRNA表达水平明显下降。IL-6、IL-8以及Ⅰ型和Ⅲ型胶原的蛋白表达水平也明显下降,但3组间再生的上颌窦黏膜中转化生长因子β(TGF-β)mRNA的表达无明显差别。结论在家兔慢性细菌性鼻窦炎创伤修复的动物模型中,上调IL-10的表达可以抑制再生黏膜中的炎症反应,减少胶原沉积,改善再生黏膜的组织重塑。
