简介：目的探讨翼状胬肉切除术后并发角巩膜病变的可能原因及相应治疗对策.方法对2009年12月至2013年5月期间于安徽省第二人民医院就诊的6例（6只眼）翼状胬肉切除术后并发角巩膜病变患者的病史、相关检查和治疗等资料进行回顾性分析.结果6例翼状胬肉患者术后并发角巩膜病变,其中2例发生角膜溃疡,分别为真菌性角膜炎和病毒性角膜炎所致；1例患者胬肉病灶切除位置烧灼引起巩膜变薄、溶解；1例患者术后发生巩膜病变,检查发现免疫指标升高；1例患者术后发生角膜脓肿,检查发现结膜囊G＋杆菌阳性；1例患者有高血压,脑梗塞,术后发生角膜溃疡.结论单纯胬肉切除、术中烧灼过度、全身抵抗力下降、自身免疫功能异常,不规范用药、术后护理不当,是翼状胬肉并发角巩膜病变的主要原因.注重全身因素影响、加强术后眼部卫生护理,翼状胬肉切除联合角膜缘干细胞移植术后及时复查治疗可避免术后严重并发症.

简介：目的探讨6～10岁屈光不正儿童复方托品酰胺与阿托品电脑验光结果的差异性.方法对诊断为屈光不正的6～10岁患儿92人(184眼),先后分别给予复方托品酰胺验光和阿托品验光,并对其结果进行比较分析.结果(1)对既往持续戴镜的不伴内斜的远视眼,其结果符合率为97.22%;对未曾戴镜的远视眼,其结果符合率为10%.(2)对既往持续戴镜的近视眼,其结果符合率为100%;未戴镜的近视眼,其结果符合率为61.76%.结论对既往持续戴镜的不伴内斜的屈光不正儿童,复方托品酰胺验光可以代替阿托品验光.

简介：目的：对一个常染色体显性遗传的先天性脉络膜缺损家系进行ABCB6基因的突变筛查,明确致病基因。方法：近来有报道ABCB6基因突变可导致先天性脉络膜缺损,我们搜集了一个中国汉族先天性脉络膜缺损家系,采集家系成员及一百位正常对照人群的静脉血5mL,使用PCR产物直接测序对ABCB6基因进行突变筛查。结果：在该家系中我们发现了一个新突变（c.1380c〉a）,该突变在家系中与疾病表型共分离,并且在100名正常对照中均未发现该突变。结论：我们的研究结果扩大了ABCB6基因的突变谱,进一步确认了该基因在眼组织缺损发病中发挥了重要作用。

简介：目的：探讨糖尿病视网膜病变（diabeticretinopathy，DR）患者血清中生长停滞特异基因6（growtharrestspecificgene6，Gas6）、基质细胞衍生因子（stromalcell-derivedfactor-1，SDF-1）和SDF-1β表达的变化及临床意义。方法：DR患者113例分为增殖性组（n=45）和非增殖性组（n=68），同期选取未合并DR糖尿病患者作为糖尿病组（49例）和健康者42例，检测血糖、血脂和超敏C-反应蛋白（highlysensitiveC-reactiveprotein，hs-CRP）指标，利用实时荧光定量PCR技术检测血清中Gas6、SDF-1α和SDF-1β基因表达。结果：糖尿病组、非增殖性组和增殖性组患者稳态模型的胰岛素抵抗指数（homeostasismodelassessmentforinsulinresistance，HOMA-IR）、甘油三酯（triglycerides，TG）和hs-CRP均逐渐升高，差异均有统计学意义（F=39.672、81.625、99.872，均P〈0.05），增殖性组和非增殖性组患者低密度脂蛋白（low-densitylipoprotein，LDL-C）均高于糖尿病组和健康者，而高密度脂蛋白（highdensitylipoprotein，HDL-C）均低于糖尿病组和健康者，差异均有统计学意义（F=51.974、43.824，均P〈0.05）；增殖性组、非增殖性组和糖尿病组患者血清Gas6mRNA表达量均高于健康者，增殖性组患者血清SDF-1αmRNA表达量均高于非增殖性组、糖尿病组和健康者，增殖性组和非增殖性组患者血清SDF-1βmRNA表达量均高于糖尿病组和健康者，且增殖性组患者高于非增殖组，差异均有统计学意义（F=15.381、21.589、38.942，P〈0.05）；Pearson相关分析显示，DR患者血清Gas6mRNA表达量与TG、总胆固醇（totalcholesterol，TC）和LDL-C呈正相关（r=0.228、0.241、0.209，均P〈0.05），血清SDF-1αmRNA和SDF-1βmRNA表达量均与hs-CRP呈正相关（r=0.297、0.325，P〈0.05）。结论：DR患者血清中Gas6、SDF-1α和SDF-1β基因表达水平升高，可能与患者血脂代谢异常及炎性反应有关。
