BackgroundReactive oxygen intermediate products lead to the oxidative injury of cells.Retinal pigment epithelial(RPE) cells produce lots of reactive oxygen intermediate products during the swallow of out disc,but how this procedure cause the persistent oxidative injury of RPE cells is poorly understood.Objective The present study was to evaluate the effect of non-lethal H2 O2 -induced persistent oxidative injury on RPE barrier in vitro.MethodsARPE-19 cell links were inoculated on 96 well plate at the density of 8×104 cells/L and the cell climbing slice of 24 well at the density of 4× 104 cells/L.The cells were cultured in DMEM/F12 medium,and the cells cultured for 24 hours in free-serum medium were used in the experiment.0-0.6 mmol/L of H2O2 were added into the medium.Cellular viability was assessed using 3- ( 4,5-dimethylthiazol-2-yl ) -5- ( 3-carboxymethoxyphenyl ) -2- ( 4-sulfophenyl ) 2H-tetrazolium(MTS) assays.Transepithelial electrical resistance (TER) was used to detect cell monolayer forming time after cultureinTrsnswellchamber.Thepermeabilityof cellmonolayer was examinedbyrhodamine isothiocyanate-dextran transepithelial flux,and immunofluorescence was used to investigate the distribution of the junction protein zonula occludens (ZO-1).ResultsThe total difference was found in the cell vitality(A490) among the different concentrations of H2 O2 ( F =991.501,P =0.000 ).Compared with 0 mmoL/L H2 O2 group,the A490 values was gradually lowed from 0.20 mmol/L H2O2 group to 0.60 mmol/L H2O2 group (P ＜ 0.05 ).H2O2 at the concentrations of ＞0.20 mmol/L lowed the viability of RPE cells.The TER value was ( 24.9 ± 1.3 ) Ω · cm2 in 11 days,( 17.8± 1.4)Ω · cm2 in 7 days after inoculation on transwell chamber,showing a significant difference between them (t=5.228,P=0.014).RPE formed the stable tight junction on day 15 with the TER value (25.9±0.9 ) Ω · cm2.The leakage amount ( relative fluorescence intensity ) of the dextran was 255.39 ± 16.44 in non-H2 O2 control group,exhibiting a significant lowing in comparison with free-cell blank group (433.08±51.53)( t =12.515,P =0.006 ),and that of H2 O2 group was significant increased in comparison with non-H2 O2 control group ( t =14.412,P=0.005).Immunofluyorescence assay showed intact intercellular ZO-1 junction in non-H2O2 control group,but the breakage of ZO-1 junction was seen in H2O2 group.ConclusionsThe results indicate that non-lethal H2O2 can destroy RPE barrier and further lead to the persistent oxidative injury of RPE cells.

Objective To evaluate the toxicity and efficacy of thermotherapy used with a streptococcus A preparation (OK-432) and cisplatin for treating malignant pleural effusion (MPE),and to assess patients' tolerance.Methods A total of 158 MPE patients were randomized into experimental and control groups.Closed drainage of the thoracic cavity was conducted with all the patients using a central venous catheter,and systematic chemotherapy was administered individually on the basis of each patient's condition.Patients in the control group were treated with intrapleural administration of OK-432 (0.5 mg) and cisplatin (40-60 mg) weekly for a maximum of 4 weeks,while those in the experimental group were given 60min of high frequency electrical thermotherapy 30-60 min after the administration of the drugs.The thermotherapy was at 40-43.5 ℃ and administered twice a week.Efficacy,quality of life and toxicity were compared between the two groups.Results The overall response rate in the experimental and control groups was 90.6% and 79.5% respectively;and grade I-II toxicity was similar.No grade Ⅲ or more serious toxicity was observed.The life quality scores in both groups were significantly improved after treatment.Conclusions Thermotherapy combined with intrapleural OK-432 and cisplatin can improve the effectiveness of therapy and life quality in MPE patients without increased toxicity.

OBJECTIVETo explore the diagnostic value of 3D-indirectmagnetic resonance (MR) arthrography in detecting meniscustears of the knees.

METHODSForm January 2013 to January 2014, routine plain MR of the knees followed by the 3D-indirect MR arthrography was performed in 42 patients with suspected meniscal tears clinically. There were 31 males and 11 females, with an average age of 38.4 years old (ranged, 21 to 67 years old). The duration of the course ranged from 2 h to 15 d. The clinical symptom was knee pain. All the patients got subsequently arthroscopic examination or operation. The sensitivity and specificity of routine plain MR and 3D-indirect MR arthrography were compared based on the results of arthroscopic examination or operation.

RESULTSThe signal intensity in the area of meniscal tears on image of 3D-indirect MR arthrography was obviously higher than that of routine plain MR. The sensitivity of 3D-indirect MR arthrography was 85.79% (87/102), while the routine plain MR was 52.94% (54/102), and the specificity improved from 67.78%(61/90) to 86.67%(78/90). The difference was statistically significant (χ2 = 25.90, P < 0.01; χ2 = 9.13, P < 0.01).

CONCLUSIONIn comparison with the routine plain MR findings, 3D-indirect MR arthrography demonstrates meniscus tears of the knee with the better sensitivity and specificity.
