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:目的探讨翼状胬肉切除术后并发角巩膜病变的可能原因及相应治疗对策.方法对2009年12月至2013年5月期间于安徽省第二人民医院就诊的6例(6只眼)翼状胬肉切除术后并发角巩膜病变患者的病史、相关检查和治疗等资料进行回顾性分析.结果6例翼状胬肉患者术后并发角巩膜病变,其中2例发生角膜溃疡,分别为真菌性角膜炎和病毒性角膜炎所致;1例患者胬肉病灶切除位置烧灼引起巩膜变薄、溶解;1例患者术后发生巩膜病变,检查发现免疫指标升高;1例患者术后发生角膜脓肿,检查发现结膜囊G+杆菌阳性;1例患者有高血压,脑梗塞,术后发生角膜溃疡.结论单纯胬肉切除、术中烧灼过度、全身抵抗力下降、自身免疫功能异常,不规范用药、术后护理不当,是翼状胬肉并发角巩膜病变的主要原因.注重全身因素影响、加强术后眼部卫生护理,翼状胬肉切除联合角膜缘干细胞移植术后及时复查治疗可避免术后严重并发症.

简介:目的:探讨糖尿病视网膜病变(diabeticretinopathy,DR)患者血清中生长停滞特异基因6(growtharrestspecificgene6,Gas6)、基质细胞衍生因子(stromalcell-derivedfactor-1,SDF-1)和SDF-1β表达的变化及临床意义。方法:DR患者113例分为增殖性组(n=45)和非增殖性组(n=68),同期选取未合并DR糖尿病患者作为糖尿病组(49例)和健康者42例,检测血糖、血脂和超敏C-反应蛋白(highlysensitiveC-reactiveprotein,hs-CRP)指标,利用实时荧光定量PCR技术检测血清中Gas6、SDF-1α和SDF-1β基因表达。结果:糖尿病组、非增殖性组和增殖性组患者稳态模型的胰岛素抵抗指数(homeostasismodelassessmentforinsulinresistance,HOMA-IR)、甘油三酯(triglycerides,TG)和hs-CRP均逐渐升高,差异均有统计学意义(F=39.672、81.625、99.872,均P〈0.05),增殖性组和非增殖性组患者低密度脂蛋白(low-densitylipoprotein,LDL-C)均高于糖尿病组和健康者,而高密度脂蛋白(highdensitylipoprotein,HDL-C)均低于糖尿病组和健康者,差异均有统计学意义(F=51.974、43.824,均P〈0.05);增殖性组、非增殖性组和糖尿病组患者血清Gas6mRNA表达量均高于健康者,增殖性组患者血清SDF-1αmRNA表达量均高于非增殖性组、糖尿病组和健康者,增殖性组和非增殖性组患者血清SDF-1βmRNA表达量均高于糖尿病组和健康者,且增殖性组患者高于非增殖组,差异均有统计学意义(F=15.381、21.589、38.942,P〈0.05);Pearson相关分析显示,DR患者血清Gas6mRNA表达量与TG、总胆固醇(totalcholesterol,TC)和LDL-C呈正相关(r=0.228、0.241、0.209,均P〈0.05),血清SDF-1αmRNA和SDF-1βmRNA表达量均与hs-CRP呈正相关(r=0.297、0.325,P〈0.05)。结论:DR患者血清中Gas6、SDF-1α和SDF-1β基因表达水平升高,可能与患者血脂代谢异常及炎性反应有关。
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。
