目的:研究视觉发育关键期单眼形觉剥夺(MD)对弱视大鼠视皮层突触密度超微形态结构变化规律的影响,以及突触素(SYN)在视皮层的表达及意义,探讨弱视大鼠视皮层突触密度及功能的关系,为弱视的发病机制及临床治疗提供分子水平理论依据。方法... 目的:研究视觉发育关键期单眼形觉剥夺(MD)对弱视大鼠视皮层突触密度超微形态结构变化规律的影响,以及突触素(SYN)在视皮层的表达及意义,探讨弱视大鼠视皮层突触密度及功能的关系,为弱视的发病机制及临床治疗提供分子水平理论依据。方法:选用正常新生Long Evans大鼠随机分为正常对照组与弱视模型组,每组16只,两组大鼠均在相同环境下饲养。正常对照组不做任何处理,弱视模型组在出生后第13d采用单眼缝合的方法建立单眼形觉剥夺性弱视经典模型。两组大鼠均于出生后51d进行闪光视觉诱发电位(F-VEP)的检测。检测结束后立即取材,用透射电镜及Image J图像分析软件观察并统计两组大鼠初级视皮层V1M区第Ⅳ~Ⅵ层大锥体细胞周围神经纤维网络的突触密度变化。利用漂染法对视皮层冰冻切片进行免疫荧光组织化学染色,在激光共聚焦显微镜及荧光显微镜下对SYN阳性神经元进行定位观察和定量统计分析。结果:F-VEP检查结果显示与正常对照组相比,弱视模型组剥夺眼的P2潜伏期较正常眼明显延长,P2波振幅较正常眼明显降低(P<0.05);透射电镜结果显示,与正常对照组相比,弱视模型组双侧视皮层的突触密度显著降低(P<0.05),其中弱视眼对侧视皮层下降更加明显(P<0.05);免疫荧光染色结果显示两组大鼠视皮层脑切片形态完整,镜下组织结构清晰,与正常对照组相比,弱视模型组SYN阳性神经元表达强度值明显降低(P<0.01)。结论:视觉发育关键期存在着突触结构可塑性,单眼形觉剥夺可以造成大鼠初级视皮层突触密度的降低,SYN表达水平下降,视皮层功能下降。 展开更多

AIM:To compare the efficacy and safety of combination of ranibizumab with photodynamic therapy(PDT)vs ranibizumab monotherapy in the treatment of age-related macular degeneration(AMD).METHODS:The Cochrane Central Register of Controlled Trials(CENTRAL)in the Cochrane Library,Pubmed,and Embase were searched.There were no language or data restrictions in the search for trials.Only randomized controlled trials(RCTs)were included.Methodological quality of the literatures was evaluated according to the Jadad Score.RevMan 5.2.6 software was used to do the meta-analysis.RESULTS:Seven studies were included in our systematic review,among which four of them were included in quantitative analysis.The result shows that the ranibizumab monotherapy group had a better mean best corrected visual acuity(BCVA)change vs baseline at month 12 compared with that of the combination treatment group,and the statistical difference was significant(WMD,-2.61;95%CI,-5.08 to-0.13;P=0.04).However,after the removal of one study,the difference between the two groups showed no significant difference(WMD,-2.29;95%CI,-4.81 to 0.23;P=0.07).Meanwhile,no significant central retinal thickness(CRT)reduction was found in the combination treatment group and the ranibizumab monotherapy group at 12 months follow-up.Nevertheless,the combination group tended to have a greater reduction in CRT(WMD,-4.13μm;95%CI,-25.88to 17.63,P=0.71).The proportion of patients gaining more than 3 lines at month 12 in the ranibizumab group was higher than in the combination group and there was a significant difference(RR,0.72;95%CI,0.54 to 0.95;P=0.02).Whereas there was no significant difference for the proportion of patients gaining more than 0 line at month12 between the two groups(RR,0.93;95%CI,0.76 to1.15;P=0.52).The general tendency shows a reduction in ranibizumab retreatment number in the combination treatment group compared with the ranibizumab monotherapy group.As major adverse events,the differences in the number of eye pain,endophthalmitis,hypertension and arterial thromboembolic events were not significant between the two groups,and the incidence of serious adverse events in the two groups was very low.CONCLUSION:For the maintenance of vision,the comparison of the combination of ranibizumab with PDT vs ranibizumab monotherapy shows no apparent difference.Compared with the combination of ranibizumab and PDT,patients treated with ranibizumab monothearpy may gain more visual acuity(VA)improvement.The combination treatment group had a tendency to reduce the number of ranibizumab retreatment.Both the two treatment strategies were well tolerated. 展开更多

AIM: To determine the differences of amino acid(AA) levels in experimental autoimmune uveoretinitis(EAU). METHODS: AA analysis of the plasma samples in EAU rats induced by interphotoreceptor retinoid-binding protein emulsion were performed with high performance liquid chromatography(HPLC) and phenylisothiocyanate(PITC) pre-column derivation methods were performed. Using partial least squares discriminant analysis(PLS-DA), the potential biomarkers were identified in EAU rat plasma, and the metabolic pathways related to EAU were further analyzed. RESULTS: The method results showed that linear(r≥0.9957), intra-day reproducible [relative standard deviation(RSD)=0.04%-1.33%], inter-day reproducible(RSD=0.06%-2.07%), repeatability(RSD=0.03%-0.89%), stability(RSD=0.05%-2.48%) and recovery(RSD=1.98%-4.39%), with detection limits of 0.853-11.4 ng/mL. The metabolic profile in EAU rats was different from that in the control groups five AAs concentrations were increased and nine AAs were reduced. Moreover, five metabolic pathways were related to the development of EAU. CONCLUSION: The developed method is a simple, rapid and convenient for determination of AAs in EAU rat plasma, and these findings will provide a comprehensiveinsight on the metabolic profiling of the pathological changes in EAU. 展开更多

AIM:To observe changes in the best-corrected visual acuity(BCVA),central macular thickness(CMT),and central choroidal thickness(CCT)of patients with macular edema(ME)secondary to ischemic retinal vein occlusion(i RVO)following intravitreal Conbercept injection.METHODS:This retrospective study included 33 eyes from 33 patients who received intravitreal injections of Conbercept for ME secondary to i RVO.Treatments were performed on a 3+pro re nata(3+PRN)basis.All of the patients were examined by fundus fluorescein angiography and spectral domain optical coherence tomography at the first visit.Laser photocoagulation was performed in the nonperfusion area of the retina of all eyes after the first injection.BCVA,CMT,and CCT were observed before and after 6 mo of treatment.The number of injections necessary to achieve improved vision was also noted.RESULTS:Following Conbercept treatment,the mean BCVA significantly improved from 0.81±0.39 at baseline to 0.41±0.25 and 0.43±0.29 log MAR in the third and sixth months,respectively(both P=0.000).The CMT of the patients at baseline was 556.75±98.57μm;304.78±68.53 and 306.85±76.77μm 3 and 6 mo after treatment,respectively(both P=0.000 vs baseline).The CCTs of the patients at baseline,3 and 6 mo after treatment were 304.63±57.83,271.31±45.53,and 272.29±39.93μm,respectively(P=0.026 and 0.035 vs baseline).No severe adverse event relevant to the therapy was noted,and the average number of injections delivered was 3.35.CONCLUSION:Intravitreal Conbercept injection combined with laser photocoagulation appears to be a safe and effective treatment for ME secondary to i RVO in the short-term. 展开更多
