  • 简介:目的:研究左氧氟沙星治疗重症细菌性角膜炎和结膜炎的疗效以及耐药性。方法:将我院收治的195例重症细菌性角膜炎和结膜炎患者作为观察对象,随机均分为A组、B组和C组,分别给予左氧氟沙星、氧氟沙星和氯霉素进行治疗,统计治疗数据,评价不同治疗方法治疗的效果和耐药性。结果:采用左氧氟沙星治疗的A组患者痊愈54例(83.1%),显效7例(10.8%),有效3例(4.6%),无效1例(1.5%);采用氧氟沙星治疗的B组患者痊愈25例(38.5%),显效6例(9.2%),有效23例(35.4%),无效11例(16.9%);采用氯霉素治疗的C组患者痊愈4例(6.2%),显效3例(4.6%),有效36例(55.4%),无效22例(33.8%),组间治疗效果和耐药性存在显著差异(P〈0.05)。结论:左氧氟沙星治疗重症细菌性结膜炎和角膜炎起效快,效果好,不易产生抗药性,值得推广借鉴。

  • 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。
