The introduction of selective laser trabeculoplasty (SLT) provided a new choice for the reduction of intraocular pressure (IOP) in eyes with open angle glaucoma (OAG) and ocular hypertension (OHT). SLT was demonstrated equally as effective as topical medical therapy and argon laser trabeculoplasty (ALT) to lower IOP. It is a potentially repeatable procedure because of the lack of coagulation damage to the trabecular meshwork (TM) and also effect in patients with previously failed ALT. SLT can be used to treat patients with OAG, pseudoexfoliation glaucoma, pigmentary glaucoma, normal-tension glaucoma, OHT, juvenile glaucoma, pseudophakic and aphakic glaucoma. Furthermore, SLT can be considered as a primary treatment option in patients who cannot tolerate or are noncompliant with medications, while not interfering with the success of future surgery. Its safety profiles include mild and transient inflammation, ocular pain and a small risk of moderate IOP elevations after the procedure. SLT is a safe and effective means of IOP reduction in eyes with OAG and OHT.

Objective:To determine whether alpha lipoic acid（LA）can effectively protect lenses from hydrogen peroxide（H2O2）-induced cataract.Methods:Lens from adult Sprague-Dawley rats were cultured in 24-well plates and treated without or with 0.2 mM of H2O2,0.2 mM of H2O2 plus 0.5 mM.1.0 mM.or 2.0 mM of LA for 24 h.Cataract was assessed using cross line grey scale measurement.Superoxide dismutase（SOD）.glutathione（GSH-Px）.lactate dehydrogenase（LDH）. and maloudialdehyde（MDA）activity or level in lens homogenates was measured.Apoptosis of lens epithelial cells in each group were detected by Terminal Deoxynucleotidyl Transferase dUTP Nick End Labeling（TUNEL） Assay.Results:A total of 0.2 mM of H2O2 induced obvious cataract formation and apoptosis in lens’ epithelial cells,but 0.5-2.0 mM of LA could block the effect of 0.2 mM H2O2 in inducing cataract and apoptosis.Furthermore.0.2 mM ol H2O2 significantly decreased SOD.GSH-Px,and LDH activity and significant increased MDA level in the lens,but 0.5-2.0 mM of LA blocked the effect of 0.2 mM H2O2.One mM of LA was found to be the most effective. Conclusions:LA can protect lens from H2O2-induced cataract.LA exerts protective effects through inhibition of lens’ epithelial cell apoptosis and activation of anti-oxidative enzymes.

AIM: To investigate the regulation and mechanisms of periostin expression in retinal Müller glia, and to explore the relevance to retinal neovascularization. METHODS: The oxygen-induced retinopathy(OIR) mouse model and the human Moorfield/Institute of Ophthalmology-Müller 1(MIO-M1) cell line were used in the study. Immunofluorescence staining was used to determine the distribution and expression of periostin and a Müller glial cell marker glutamine synthetase(GS). Cytokines TNF-α and IFN-γ were added to stimulate the MIO-M1 cells. ShRNA was used to knockdown periostin expression in MIO-M1 cells. Quantitative real-time reverse transcription polymerase chain reaction(qRT-PCR) was conducted to assess the mRNA expression of periostin. RESULTS: Immunofluorescence staining showed that periostin was expressed by MIO-M1 Müller glia. GS-positive Müller glia and periostin increased in OIR retinas, and were partially overlaid. The stimulation of TNF-α and IFN-γ reduced the mRNA expression of periostin significantly and dose-dependently in MIO-M1 cells. Knockdown of periostin reduced mRNA expression of vascular endothelial growth factor A(VEGFA) in MIO-M1 cells, while VEGFA expression was not changed in periostin knock-out OIR retinas. CONCLUSION: Müller glia could be one of the main sources of periostin in the retina, and might contribute to the pathogenesis of retinal neovascularization. Proinflammatory cytokines TNF-α and IFN-γ attenuate the periostin expression in retinal Müller glia, which provides a potential and novel method in treating retinal neovascular diseases.

Because of a lack of sensitive biomarkers,the diagnosis of Alzheimer＇s disease（AD） cannot be made prior to symptom manifestation.Therefore,it is crucial to identify novel biomarkers for the presymptomatic diagnosis of AD.While brain lesions are a major feature of AD,retinal pathological changes also occur in patients.In this study,we investigated the temporal changes in β-site APP-cleaving enzyme 1（BACE1） expression in the retina and brain to determine whether it could serve as a suitable biomarker for early monitoring of AD.APP/PS-1 transgenic mice,3,6 and 8 months of age,were used as an experimental group,and age-matched C57/BL6 wild-type mice served as the control group.In the Morris water maze test,there were no significant differences in escape latency or in the number of crossings in the target area among mice of different ages.Compared with wild-type mice,no changes in learning or memory abilities were detected in transgenic mice at 3 months of age.However,compared with wild-type mice,the escape latency was significantly increased in transgenic mice at 6 months,starting on day 3,and at 8 months,starting on day 2,during Morris water maze training.In addition,the number of crossings of the target area was significantly decreased in transgenic mice.The learning and memory abilities of transgenic mice were further worsened at 8 months of age.Immunohistochemical staining revealed no BACE1 plaques in wild-type mice at 3,6 or 8 months or in transgenic mice at 3 months,but they were clearly found in the entorhinal cortex,hippocampus and prefrontal cortex of transgenic mice at 6 and 8 months.BACE1 expression was not detected in the retina of wild-type mice at 3 months,but weak BACE1 expression was detected in the ganglion cell layer,inner plexiform layer and outer plexiform layer at 6 and 8 months.In transgenic mice,BACE1 expression in the ganglion cell layer was increased at 3 months,and BACE1 expression in the ganglion cell layer,inner plexiform layer and outer plexiform layer was significantly increased at 6 and

Previous studies have shown that Biochanin A,a flavonoid compound with estrogenic effects,can serve as a neuroprotective agent in the context of cerebral ischemia/reperfusion injury;howeve r,its effect on spinal cord injury is still unclea r. In this study,a rat model of spinal cord injury was established using the heavy o bject impact method,and the rats were then treated with Biochanin A(40 mg/kg) via intrape ritoneal injection for 14 consecutive days.The res ults showed that Biochanin A effectively alleviated spinal cord neuronal injury and spinal co rd tissue injury,reduced inflammation and oxidative stress in spinal cord neuro ns,and reduced apoptosis and pyroptosis.In addition,Biochanin A inhibited the expression of inflammasome-related proteins(ASC,NLRP3,and GSDMD)and the Toll-like receptor 4/nuclear factor-κB pathway,activated the Nrf2/heme oxygenase 1 signaling pathway,and increased the expression of the autophagy markers LC3 Ⅱ,Beclin-1,and P62.Moreove r,the therapeutic effects of Biochanin A on early post-s pinal cord injury were similar to those of methylprednisolone.These findings suggest that Biochanin A protected neurons in the injured spinal cord through the Toll-like receptor 4/nuclear factor κB and Nrf2/heme oxygenase 1 signaling pathways.These findings suggest that Biochanin A can alleviate post-spinal cord injury at an early stage.
