目的探讨表面麻醉下白内障超声乳化术治疗高度近视合并年龄相关性白内障的临床疗效。方法对我院2009年1月至2010年12月高度近视合并年龄相关性白内障患者48例(48眼)进行回顾性分析,所有患者在表面麻醉下行白内障超声乳化人工晶状体植入术,术后3d、1个月、3个月检查记录患者术后视力情况,并采用直接检眼镜检查眼底,观察术后屈光状态、眼压及并发症情况。结果术中3眼发生后囊膜破裂,给予前房玻璃体清除及虹膜周边切除术,均顺利植入人工晶状体;2眼出现晶状体悬韧带部分断裂,经加大黏弹剂剂量后顺利植入人工晶状体。除2眼外,其余患眼术后视力较术前均有显著提高,差异均有显著统计学意义(均为P<0.01)。术后3个月实际与预计植入屈光度差值为(3.28±1.44)D,平均(-2.52±2.13)D。术后后囊膜混浊13眼,其中9眼行Nd:YAG激光后囊膜切开术;虹膜后粘连3眼;5眼出现一过性高眼压,多在术后2～3d内自行恢复;未见其他明显的术后并发症。结论表面麻醉下白内障超声乳化术治疗高度近视合并年龄相关性白内障具有手术时间短、切口小、痛苦少、恢复快等优点,是较理想和值得推广的方法。

Quantum walks(QW) are the quantum counterpart of classical random walks, and portray a natural stochastic process when the walker randomly wanders around. In a discretetime QW system on a circle, when the walker particle generally steps towards two directions, i.e., clockwise and anticlockwise, this kind of QW is called two-direction quantum walks on a circle(TDQWC); and the walker particle always steps towards one direction or stays stationary, this kind of QW is called as one-direction quantum walks on a circle(ODQWC). ODQWC exhibits some different properties,and may induce potential applications in the field of quantum secure multi-party computation.

目的:探讨糖尿病患者与非糖尿病患者行玻璃体视网膜手术前后对角膜内皮细胞密度和形态学的影响。方法:收集60例患有糖尿病患者(糖尿病组)和60例非糖尿病患者(对照组),其中30例糖尿病组和30例对照组患者行玻璃体切割联合硅油填充手术,30例糖尿病组和30例对照组患者行晶状体玻璃体切割联合硅油填充手术。检测两组患者术前1d及术后3mo角膜内皮细胞密度(cell densities,CD)、内皮细胞面积变异系数(coefficient of variation,CV)、六角形细胞百分比值(ratio of hexagonal cells,RHC)。比较两组患者手术前后角膜内皮细胞变化的差异。结果:玻璃体切割联合硅油填充术在糖尿病组与对照组角膜内皮细胞变异系数和六角形细胞百分比手术前后相比差异均有统计学意义,晶状体玻璃体切割联合硅油填充术在糖尿病组和对照组角膜内皮细胞密度、变异系数及六角形细胞百分比手术前后相比差异均有统计学意义;晶状体玻璃体切割联合硅油填充术在糖尿病组手术前后角膜内皮细胞密度、变异系数、六角形细胞百分比的差值与对照组相比差异有统计学意义。结论:玻璃体切割联合硅油填充手术对角膜的影响主要表现在角膜内皮细胞的形态改变;而与非糖尿病患者相比,糖尿病患者行晶状体玻璃体切割联合硅油填充术角膜内皮细胞形态、密度的改变较非糖尿病患者明显,因此术前角膜内皮细胞的严格检查对于糖尿病患者术后视觉的恢复具有重要意义。
