AIM:To evaluate the efficacy and safety of methazolamide in treating refractory uveitic macular edema.METHODS: Retrospective self-controlled study was designed.A total of 15 patients (20 eyes) with refractory uveitic macular edema which used methazolamide as adjuvant therapy were enrolled in Shanghai First People`s Hospital from January 2015 to June 2016.The changes of central macular thickness (CMT) and best corrected visual acuity (BCVA) were observed at baseline and 2, 4, 8wk after treatment.We also focused on the incidence of complications and relapse.RESULTS: The CMT was 445.95±154.10μm, 338.83±138.34μm, 251.50±40.20μm, 244.90±35.68μm at baseline, 2, 4 and 8wk after treatment, respectively.The differences among them were statistically significant (F=15.467, P<0.05).The BCVA (log MAR) were 0.40±0.17, 0.28±0.21, 0.19±0.20, 0.18±0.21 at baseline, 2, 4 and 8wk respectively, with a significant difference among them (F=5.208, P<0.05).When the cumulative dose reached to 700mg and 1400mg, no one had methazolamide-related complications;and when it came to 2800mg, 5 patients (33%) had methazolamide-related complication.After the withdrawal of methazolamide 1wk, 1 and 3mo, 3 patients (20%), 5 patients (33%) and 8 patients (53%) relapsed, respectively.CONCLUSION: Methazolamide is beneficial in improving macular edema and vision in 4wk.When the cumulative dose is more than 1400mg, we need pay attention to the complications.After discontinuing methazolamide for 1wk, macular edema relapsed in some patients, and more than half of patients recurred after 3mo.So the patients should be followed closely in 3mo after withdrawal of methazolamide.

Objective: To investigate the effect of adhesion of Lactobacillus reuteri JCM1081 to enterocyte-like HT-29 cells on filamentous cytoskeleton.Methods:Cultured human intestinal enterocyte-like HT-29 cells were used.Cell permeability was examined in vitro by Evans blue labeled albumin and Examination of F-actin was conducted by direct immuno-fluorescence labeling using fluorescein labeled phalloidin.Results:Lactobacillus reuteri JCM1081 did not alter cell integrity and prevented the increase in permeability induced by enteropathogenic Escherichia coli infection.The distribution of F-actin were also not altered.Conclusion :Lactobacillus reuteri JCM1081 exerts a protective effect against the filamentous cytoskeleton rearrangement and permeability lesions promoted by enteropathogenic Escherichia coli infection.

Objective To study the adhesive characters of Lactobacillus to enterocyte-like HT-29 cells.Methods A HT-29 cell culture was employed to investigate the adherent ability of Lactobacillus.Bacterial suspension and HT-29 cells were co-incubated at 37℃ for 1h.The cells with adherent bacteria were Gram-stained,and then examined microscopically under oil immersion.The pH of the medium,bacterial growth phase,co-incubation time,bacterial concentration,D-mannose and type of host cells,which were involved in the process of adherence of Lactobacillus to enterocyte-like HT-29 cells,were also investigated.Results The adherent level increased substantially for Lactobacillus reuteri JCM1081 as the pH decreased from 6.0 to 4.0.Maximum adherence occurred within 90min and remained stable until the end of incubation.The bacterial concentration exerted a certain influence on the adherence of Lactobacillus reuteri JCM1081 to HT-29 cells,and it seemed to be concentration dependent.Maximum adherence occurred in the concentration of 109cfu/ml and remained stable until the end of incubation.Lactobacillus strain that grew into stationary phase showed higher ability to adhere to HT-29 cells than that in logarithmic phase.The addition of D-mannose dramatically decreased the level of Lactobacillus adherence.The Lactobacillus strain adhered in higher levels to the enterocyte-like cells or gastric epithelium cells than other cell origins,and the adhesion of Lactobacillus showed host cells specificity.Conclusion The adhesive characters observed with Lactobacillus suggested that adhesive properties are species and host specific.The pH,bacterial growth phase,co-incubation time,bacterial concentration and D-mannose may influence the adhesion of Lactobacillus to enterocyte-like HT-29 cells.
