简介：目的在视网膜缺血再灌注模型上，观察再灌注后视网膜内caspase-3的动态变化，探讨caspase-3与视网膜细胞凋亡的关系。方法结扎大鼠左侧颈总动脉1h，然后再灌注，检测再灌注后1、6、12、24、48、72h大鼠视网膜内caspase-3的水平及视网膜细胞凋亡平均发生率。结果再灌注后视网膜内caspase-3的表达出现在光感受器细胞层，在再灌注后1、6、12、24、48、72hcaspase-3平均光密度分别为0．067±0．004、0．923±0．045、1．962±0．377、3．793±0．860、2．039±0．427、1．332±0．109，细胞凋亡平均发生率（％）分别为1．8±0．1，7．1±0．2，18．2±1．4，34．7±2．1，22．6±0．9，16．3±0．4。结论再灌注后大鼠视网膜caspase-3表达与细胞凋亡呈现正相关，caspase-3可以促进视网膜细胞凋亡的发生。

简介：目的：对比分析伴虹膜异色的青光眼睫状体炎综合征与Fuchs综合征患者的临床表现及特点,对两种疾病的鉴别要点作出分析及总结,利于临床医生对这两种疾病进行鉴别诊断。方法：对本院自2000年至今收治住院的3例伴虹膜异色的青光眼睫状体炎综合征（Posner-Schlossman’ssyndrome,PSS）患者进行详细的临床检查及研究,根据其临床资料总结出该病的临床特点,并对伴虹膜异色的PSS与Fuchs综合征的鉴别要点作出分析及总结。结果：共收集了3例伴虹膜异色的PSS患者,均为单眼反复发病,病程均在10a以上,发作时眼压明显升高,可达30.00～60.00mmHg,持续时间一般为3～7d,可自行缓解或用药后缓解,间歇期眼压正常,该3例患者除了具有典型的PSS表现外,虹膜均轻度异色。总结了该病在发作期及间歇期的临床表现,从发病情况、眼压波动情况、KP形态、晶状体情况、眼底及视功能情况详细论述了伴虹膜异色的青光眼睫状体炎综合征与Fuchs综合征的区别,并针对两种疾病的治疗提出了不同建议。结论：结合我们所提出的鉴别要点,对患者进行详细的临床检查,可以对这两种疾病进行鉴别诊断。

简介：白内障是最常见的致盲眼病之一。谷胱甘肽S转移酶（glutathioneS-transferases,GSTs）是典型的多功能酶,主要催化各种化学剂与谷胱甘肽结合。近些年的研究表明,GSTs有抗过氧化引起的白内障作用。GSTs表达水平的高低在白内障形成中有着重要的作用。我们将近年来GSTs与年龄相关性白内障的研究情况做一综述。
