简介：目的：探讨眼附属器B细胞非霍杰金淋巴瘤（B—cellnon-Hodgkinlymphoma，NHL）中Skp2，p27和PTEN的表达。方法：收集1995年到2011年青岛大学附属医院眼科石蜡包埋标本，用免疫组化法分别检测眼附属器B细胞NHL（n=30）标本中Skp2，p27和PTEN的表达，以眼部反应性淋巴组织增生（n=10）作为对照组。以患者的年龄、性别、发病部位，病理类型作为眼附属器B细胞NHL的的分类标准。结果：Skp2，p27和PTEN的表达与患者的年龄、性别、发病部位无关，而与病例类型有关。眼附属器B细胞NHLSkp2表达率与眼部反应性淋巴组织增生相比显著增高。p27，PTEN表达率与反应性淋巴组织增生相比显著降低。随眼附属器B细胞NHL病理分级的提高，Skp2的表达显著增高，p27和PTEN的表达显著降低。在黏膜相关淋巴组织结（mucosa—associatedlymphoidtissue，MALT）外边缘区B细胞淋巴瘤（diffuselargeB—celllymphoma，DLBCL）中，Skp2分别与p27，VFEN成负相关，p27和PTEN成正相关。结论：Skp2的表达升高，p27，PTEN蛋白的缺失以及可能与眼附属器B细胞NHL的发生有关；其中在MALT外边缘区DLBCL中，三种蛋白存在相关性。联合三种蛋白的检测眼附属器B细胞NHL的不同病理类型有重要意义。

简介：目的：分析23G玻璃体切割术后高眼压的发生率、特点及相关的危险因素,为处理及预防提供依据。方法：对于我院行23G玻璃体切割手术的患者146眼临床资料进行回顾分析,术后早期高眼压诊断标准为术后2wk内任一时间眼压测量值≥25mmHg。采用卡方检验进行统计学分析;对于术后早期高眼压患者根据眼压程度采用单一或联合降眼压药物治疗。结果：患者146眼中发生术后高眼压者42眼,占28.8%,平均出现自术后3.38d。单纯气换组、C3F8填充组及硅油填充组术后高眼压发生率分别为14.5%,33.3%和39.3%,C3F8组和硅油填充组与单纯气换组比较均有统计学意义;未行激光机冷冻处理组、部分视网膜光凝组、全视网膜光凝组及冷冻组术后早期高眼压的发生率分别为13.6%,27.4%,34.5%和35.7%,部分视网膜光凝组与未处理组相比较没有统计学意义,而其他两组与未处理组比较有统计学意义;不同原发病术后均有早期高眼压的发生,但分布不均衡。通过处理眼压均控制理想。结论：23G玻璃体切割术后早期高眼压的危险因素是多方面的,主要与眼内填充物、术中处理方式有关,不同原发病对于高眼压的影响在于其对术式的影响。术后早期高眼压多为一过性,合理药物治疗可控制。
