  • 简介:儿童眼球生长、发育及稳定离不开眼球血管发生和成熟。正常视网膜血管形成起始于血管生成(vasculogenesis),终止于血管新生(angiogenesis)。促血管生成因子(pro-angiogenicfactors)和抗血管生成因子(anti-angiogenicfactors)共同作用调节血管新生过程。缺氧和炎症等多种刺激可以导致病理性血管新生[1]。

  • 简介:目的:研究角膜胶原交联方法联合那他霉素应用时体内外抗真菌效果,为临床真菌性角膜炎治疗提供治疗方法及实验基础。方法:采用黄曲霉菌、茄病镰刀菌、白色念珠菌三常见致病真菌,实验组分为交联联合那他霉素组、那他霉素联合核黄素组、那他霉素联合紫外照射组、交联组,并用那他霉素组作为对照。将药物涂到有1.5麦氏浊度真菌孢子悬液沙堡弱琼脂培养皿中心,10min后使用胶原交联仪照射10min,之后28℃培养36h,测量抑菌圈并进行统计学分析。制备兔眼茄病镰刀菌感染模型,按随机数字表法将模型兔随机分为模型对照组、交联治疗组、那他霉素治疗组、交联联合那他霉素治疗组,每组5只;另取5只正常兔按照角膜胶原交联疗法进行照射,5只正常对照。通过前节照相、角膜刮片、共焦显微镜等观察各组治疗结果,并在治疗结束后采用电镜观察角膜超微结构改变情况。结果:体外单独应用角膜胶原交联术,对三真菌均无效;当交联与那他霉素联合应用时,抗真菌效果均优于对照组,且差异具有统计学意义(P<0.05);那他霉素与核黄素、那他霉素与紫外线分别联合应用时,抗菌效果与对照组比较,差异均无统计学意义(P>0.05)。针对兔真菌感染模型,那他霉素治疗组及交联联合那他霉素治疗组病程约14d,交联治疗组病程约21d;经治疗后,各治疗组均已愈合,各组角膜上皮均无缺损,新生血管较多,角膜内无菌丝;前节照相结果显示,交联联合那他霉素治疗治疗结果优于其它各治疗组,瘢痕组织较少,角膜愈合较好,病程相对短。结论:角膜胶原交联方法联合那他霉素,可促进角膜愈合,缩短病程,增强抗真菌效果,有望为眼科临床真菌性角膜炎治疗提供治疗技术。
