简介：目的：探索相对稳定性强、一致性好的大鼠角膜碱烧伤动物模型。方法：将87只SD大鼠分为角膜缘碱烧伤20s组（A组。34只），角膜缘碱烧伤40s组（B组，23只），角膜中央碱烧伤40s组（C组，30只），用浸润1mol／L氢氧化钠的滤纸片，分别烧灼大鼠角膜缘和角膜中央，术后7d裂隙灯显微镜观察角膜透明度、角膜溃疡及角膜新生血管情况，并记录上述指标。结果：角膜缘碱烧伤（B组）较角膜中央烧伤（c组）溃疡发生率、角膜穿孔率和角膜上皮荧光素钠染色阳性率高，且有统计学差异（P〈0．05）；角膜缘烧灼时间长组（B组）溃疡发生率及角膜穿孔率高于角膜缘烧灼时间短组（A组），且有统计学差异（P〈0．05）；烧灼角膜缘和角膜中央（A，B，c组）均能诱导出角膜新生血管。结论：对于研究角膜新生血管的动物模型，以选择3mm圆形滤纸片角膜中央烧伤为佳；对于研究角膜缘干细胞缺乏所致角膜病变的实验，以选择环形滤纸片放置于角膜缘20s为佳。

简介：目的探讨两种不同手术方式治疗翼状胬肉对泪液功能的影响及影响因素。方法选取翼状胬肉患者40例（40只眼）随机分成两组：A组20个病人（20只眼）翼状胬肉切除联合冻干羊膜移植术；B组20＋病人（20只眼）翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术。术前，术后1mo，术后3mo行泪膜破裂时间（BUT）、泪液分泌试验（SchirmerI）、角膜荧光素染色（CSF），评价翼状胬肉及翼状胬肉切除术后泪膜功能变化对患者生活质量的影响。结果两组病人术后lmoBUT缩短，角膜荧光素染色增多，差异有统计学意义（P〈0．05），而术后SchirmerI与术前相比无统计学意义，两组术后3moBUT，SchirmerI，CFS与术前相比无统计学意义，翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术组术后早期泪膜稳定性优于翼状胬肉切除联合冻干羊膜移植术，差异具有统计学意义∞〈0．05）。结论翼状胬肉切除术早期对泪膜功能有影响。翼状胬肉切除联合带自体角膜缘干细胞结膜瓣移植术早期对泪膜的影响小于翼状胬肉切除联合冻干羊膜移植术。

简介：护理安全是指在实施护理的全过程中，患者不发生法律和法定的规章制度允许范围内以外的心理、机体结构或功能上的损害、障碍、缺陷或死亡。通过对护理安全问题的分析，认为造成护理安全问题和护患纠纷的主要原因有护理人员方面的、管理方面及病人、社会方面的。只有依法行医、恪尽职守、加强自律和道德建设、规范服务行为、改善社会对医院的再认识，建立协调健康的医护关系，合理应用人力资源，优化护理管理制度，增强护理风险意识才能有效解决护理安全问题。

简介：对于原发性开角型青光眼（POAG），治疗的基本原则是通过药物、手术或激光等方式降低眼压，但是患者的日常生活习惯对治疗后眼压的控制、病情的缓解有着不可忽视的影响。日常生活中影响眼压和POAG病情发展的相关因素主要有饮酒、吸烟、运动、肥胖和饮用咖啡、茶等。本文主要就流行病学调查方面研究结果，进行了分析总结，提出在日常生活方面的注意事项，给眼科医生提供相关信息，给患者提供生活指导。

简介：目的：探讨机械性眼外伤的临床特征及诊疗结果分析。方法：收集我院收治的机械性眼外伤122例122眼的临床资料,进行记录及回顾性分析。结果：机械性眼外伤122例中,开放性眼外伤116眼（95.1%）,闭合性眼外伤6眼（4.9%）,男女之比6.18∶1,机械性眼外伤以眼球开放性损伤为最多,致伤多以异物为主,经过及时手术治疗,全部保住了眼球,与入院视力相比,出院视力得到明显提高。结论：工作和生产意外是机械性眼外伤的主要原因,病情复杂,合并症多,后果严重,应加强防范。及时的医院就诊和眼科显微手术技术的提高及玻璃体视网膜手术的开展是挽救伤眼视力、降低机械性眼外伤并发症的有效措施。

简介：目的：通过对比姜黄素与Avastin抑制大鼠碱烧伤后角膜新生血管（cornealneovascularization,CNV）及血管内皮生长因子（vascularendothelialgrowthfactor,VEGF）表达水平的影响,进一步探讨姜黄素抑制CNV形成的机制。方法：选取SD大白鼠共30只,建立碱烧伤模型,随机将大鼠分成A,B两组,各15只,A组中右眼为实验组A1组,左眼为空白对照组A2;B组中右眼为实验组B1,左眼为空白对照组B2。A1组给予40μmol/L姜黄素配置成的滴眼液,A2组滴用生理盐水;B1组给予5g/LAvastin滴眼液,B2组滴用生理盐水。根据不同时间点取角膜组织进行病理切片研究、抽取房水进行ELISA测定,计算出每视野计数微新生血管及房水中VEGF含量。对以上指标进行对比分析研究。结果：两种药物均未发现在角膜水肿、角膜修复等方面的毒副作用。对新生血管的影响,两种药物CNV计数均明显低于空白对照组（P〈0.01）,两种药物之间对新生血管影响的对照,平均CNV计数无显著性区别。A1组与A2组对比、B1组与B2组对比,实验组VEGF均明显低于对照组,有高度显著性统计学意义（P〈0.01）,A1组与B1组对照,平均VEGF含量A1组高于B1组,有统计学意义（P〈0.05）。结论：姜黄素的VEGF抑制能力可能不如Avastin,但在整体抗CNV的能力上并不输于Avastin,说明姜黄素还参与了干预角膜碱烧伤CNV形成的其他机制。
