简介：AIMTo报告角膜的营养障碍(液晶显示器)与二个变化，R124C和A546D联系了的格子的一个phenotypic变体家谱，在导致贝它的基因(TGFBI).METHODSA详细说明了的转变生长因素，眼睛的检查为一个液晶显示器家庭的所有参加者被参加。从每个参加者的外部血白血球被提取获得DNA。TGFBI基因的所有十七exons的聚合酶链反应(PCR)被执行。产品被定序并且分析。在从proband.RESULTSGenetic分析的右眼睛的渗透的keratoplasty证明proband和所有6个影响个人两个都在codon怀有异质接合的CGC到TGC变化以后，组织学的检查被执行124并且异质接合的GCC到在codon的GAC变化546TGFBI。任何一个100个控制题目和未受影响的家庭成员都不为这二个变化是积极的。眼睛的检查显示了多重refractile在在外部角膜的中央角膜和小小粒的存款的前面的基质的像格子的暗。存款与红显示是的刚果断然被染色在自然淀粉、位于主要观察的前面、中间的stroma.CONCLUSIONWe在TGFBI基因带了二个病原的变化(R124C和A546D)的一个新奇液晶显示器家庭。phenotypic特征与与相应单个变化联系的那些显然不同。结果表明尽管明确的变化是疾病的最重要的基因原因，一些不同修饰词等位基因可以影响显型。

简介：AIMTo在cells.METHODSARPE-19细胞是的网膜的颜料上皮(RPE)上调查高葡萄糖层次和反脉管的endothelial生长因素(VEGF)代理人(bevacizumab，ranibizumab和aflibercept)的效果在不同葡萄糖层次(5.5mmol/L，25mmol/L，和75mmol/L)有教养。房间生存能力被MTT试金与D葡萄糖在处理以后在3d评估。房间迁居能力被创伤愈合试金在3d测量。一个房间死亡察觉工具包被用来在3点估计apoptosis并且14d。房间增长被EdU试金在3d估计。文化媒介在临床上相关的集中与anti-VEGF代理人被对待。实验然后在一个不同葡萄糖level.RESULTSThe生存能力被重复，ARPE-19房间的移植显著地作为与5.5mmol/L葡萄糖相比面对75mmol/L被减少。TUNEL积极的房间的百分比显著地被增加，proliferative潜力与5.5mmol/L葡萄糖相比与75mmol/L被减少。在在25mmol/L和5.5mmol/L葡萄糖之间的结果没有重要差别。面对75mmol/L葡萄糖，与anti-VEGF对待的组显示出减少的房间生存能力和增长并且增加了apoptosis。然而，anti-VEGFgroups.CONCLUSIONHigh葡萄糖水平减少之间没有重要差别RPE房间的生存能力，创伤愈合能力，和增长，当增加apoptosis时。而且，anti-VEGF代理人在高葡萄糖的条件下面防碍RPE房间的生理的功能，在房间生存能力和增长由减少伴随了。
