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: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。

简介:目的:评估以不同的方法治疗病毒性结膜炎并发症泪小点及泪小管闭塞的疗效。方法:此回顾性群组研究共纳入35例临床确诊为感染病毒性结膜炎的患者,经治疗后完全缓解,4wk后并发泪小点闭塞。本研究采用了泪小点扩张术,穿孔硅胶泪小点栓子植入术,和Mini-Monoka硅胶管植入术对该35例泪小点闭塞患者进行治疗。结果:首先,单独采用泪小点扩张术对所有35例患者进行治疗,其中只有6例患者(17.14%)取得了满意的疗效。其次,采用穿孔泪小点栓子植入术对上述采用泪小点扩张术无效的患者进行治疗,有20例(57.14%)患者取得了较好的疗效。最后,采用Mini-Monoka管植入术对上述两种治疗方案都无效的患者进行治疗,有9例(25.71%)患者的病情取得了重大的改善。另外,通过对上述病例进行统计分析,结果表明该疾病的严重程度与Mini-Monoka管的使用和是否双眼同时患病或者和上、下泪小点同时闭塞并无关联。结论:运用穿孔硅胶泪小点栓子能够有效治疗由病毒性结膜炎引起的泪小点闭塞。对分别经泪小点扩张术和穿孔硅胶泪小点栓子植入术治疗无效的患者,可采用Mini-Monoka管植入术以取得良好的治疗效果。

简介:目的研究面神经损伤后对其运动神经元死亡的影响。方法以大鼠为研究对象,设计出5种面神经受损的实验模型,即面神经低位断伤,面神经高位断伤,面神经茎乳孔压榨伤,面神经茎乳孔牵拉伤,面神经茎乳孔切断后立即桥接。各组动物饲养1月后取其面神经核团,经CresylViolet染色,在显微镜下计算右,左侧面神经核团中运动神经元数目之比。结果实验表明:面神经低位断伤,高位断伤,压榨伤,牵拉伤,切断后立即桥接其运动神经元胞体存活率分别为78.26%,69.23%,94.02%,81.58%和83.85%,面神经低位断伤后运动神经元存活率同其它各组比较发现:面神经低位断伤后其运动神经元存活率比高位断伤者高,较面神经压榨伤和面神经切断后立即桥接低,同面神经牵拉伤者没有明显差异。结论面神经受损后其运动神经元数目的变化同损伤部位,损伤程度,以及损伤后的修复有关,为面神经损伤后手术时机的把握和手术方法的选择提供理论依据。

简介:目的以接受免费白内障手术的患者电话随访结果为依据,对我省防盲项目完成效果进行评价、分析,探讨提出加强和完善基层医院眼科参与大规模防盲项目患者的可持续随访体系。方法通过以电话随访的方式,对2012年云南省'光明工程'6万例免费白内障手术患者中随机抽取2000例患者就手术视力提高程度及满意度进行电话随访。随访统一使用云南省卫生厅《2012年云南省'光明工程'患者电话随访表》,由专人于4周内完成电话随访。结果患者术后视力明显提高者占90.20%;患者对术后满意度达93.27%;从生活不能自理到能自理占86.41%;术后生活质量明显提高占85.79%;术后患眼有不适者占17.76%;知道如出现不适如何处理的患者占70%;新农合占93.81%,居民医保5.56%,职工医保1.64%,其他医保占0.88%;所有患者均为免费手术,无自付比例。结论在基层开展大规模集中白内障防盲项目的过程中,在严格监控患者术后质量、手术费用、住院天数、降低患者的医疗费用的同时,更应该加强对手术患者的长效管理机制,建立合理的患者随访体系,总结经验,不断完善工作流程,真正改善患者的生活质量,提高患者满意度,体现防盲工作的真正含义。
