Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value. 相似文献

磁共振成像、视诱发电位和视野检查在视神经炎的临床应用 总被引:4,自引:0,他引:4
目的 探讨MRI、视诱发电位(VEP)和视野(Vision Field,VF)在视神经炎中的临床应用价值。方法 临床诊断为视神经炎者60例分别行MRI、VEP和视野检查,每例所有检查均在一周内完成,并将检查结果进行统计学处理和分析。结果 MRI阳性率最高(96.67%),其次是视野和VEP(86.96%和75.58%)。同时发现MRI具有定位和一定的鉴别诊断作用。结论 VEP和VF结合MRI检查,三者相辅相成,将有助于视神经炎更早、更准确地诊断和治疗。 相似文献

晶状体上皮及纤维均有钠钾-ATP酶的表达,其在上皮中的活性高于纤维中.大量的研究表明上皮中钠钾-ATP酶介导的离子转运对调节整个晶状体的离子分布具有重要的意义.晶状体内钠离子的异常分布与年龄相关性白内障中皮质混浊程度具有相关性.钠钾-ATP酶容易受到氧化、磷酸化等影响而活性下降;而谷胱甘肽(GSH)、抗坏血酸等保护钠钾-ATP酶的活性.本文就晶状体上钠钾-ATP酶的研究进展进行简要综述,并对该领域的研究前景进行展望. 相似文献

目的探讨术后抗炎汤对白内障患者手术后血清与泪液白细胞介素2(SIL-2R)的影响及其临床意义.方法15例正常健康老人和47例白内障超声乳化加人工晶状体植入术患者随机分为正常组、对照组和中药组,中药组是在对照组药物基础上加用术后抗炎汤.检测白内障患者手术前后血清和泪液SIL-2R水平的变化.结果对照组和中药组术后血清SIL-2R均比术前明显升高(P<0.05),中药组术后泪液SIL-2R与术前相比差异无统计学意义(P>0.05),对照组术后SIL-2R水平明显高于中药组和正常组(P<0.01).结论术后抗炎汤能有效减轻白内障术后的炎症反应,其机理可能是调节眼局部免疫功能. 相似文献

角膜移植患者外周血中T细胞CD28分子的表达及其意义 总被引:3,自引:0,他引:3
目的 探讨角膜移植患者外周血T细胞及亚群CD2 8分子表达的变化及其意义。方法 于术前1d、术后第1、2、3、4周,应用流式细胞仪检测2 5例角膜移植患者外周血中CD2 8分子表达水平的变化。结果 角膜高血管化植床组患者术后外周血T细胞CD2 8分子表达比角膜无血管化植床组患者明显增高,也比术前明显增高(P <0 .0 1) ;6例发生排斥反应的患者均出于高血管化植床组;术后早期外周血T细胞中以CD4 + 细胞为主。结论 外周血T细胞CD2 8分子表达与角膜移植排斥反应关系密切,检测角膜移植患者外周血中的CD2 8分子表达可更早监测免疫排斥反应的发生 相似文献

实验性异种穿透性角膜移植的免疫学研究 总被引:1,自引:0,他引:1
本文以鸡给兔的穿透性角膜移植为实验模型,运用微量全血~3H-TdR掺入法和ELISA,对术后动物机体的细胞和体液免疫功能状态变化进行了10周动态观察.发现:(1)术后同种和异种组外周血中淋巴细胞转化程度均增高,以3~4周最明显.(2)异种组术后2~8周血清中明显出现特异性抗角膜抗体,第3周达峰值,结合形态学观察证明:(1)术后免疫排斥反应主要是细胞介导的免疫应答,也有体液免疫的参与,异种移植体液免疫参与更明显,(2)运用微量全血~3H-TdR掺入法可有效监测术后机体免疫功能状态的变化.(3)使用免疫抑制剂应该重视术后3~4周. 相似文献
