@#AIM: To evaluate the clinical effects of using technetium-99 methylene diphosphonate(99Tc-MDP)with methylprednisolone to treat thyroid-associated ophthalmopathy(TAO). <p>METHODS: We retrieved from 9 databases, from their foundation to March 2019, including Pubmed, the Cochrane Library, EMbase,, Web of Science, CNKl, VIP database, China Biology Medicine disc, Wanfang database and collected the randomized controlled trail(RCT)of 99Tc-MDP combined with methylprednisolone for treatment of TAO. According to inclusion and exclusion criteria, two researchers retrieved the literature independently, extracted data and evaluate methodological quality. Meta analysis was performed by Review Manager 5.3 software.<p>RESULTS: A total of 8 RCTs were identified with 644 patients. There was significant difference in the overall clinical effective rate between 99Tc-MDP combined with methylprednisolone and methylprednisolone alone(<i>RR</i>=1.14, 95% <i>CI</i>: 1.03-1.26, <i>P</i>=0.01). Significant difierence was found in the effective rate of proptosis between intravenous injection of 99Tc-MDP with methyprednisone and methyprednisone only(<i>RR</i>=1.28, <i>95% CI</i>: 1.16-1.41, <i>P</i><0.00001). Meanwhile, great improvement was seen in diplopia(<i>RR</i>=1.64, <i>95% CI</i>: 1.04-2.58, <i>P</i>=0.03), but there was no significant difference in disturbance of ocular dyskinesia(<i>P</i>=0.37).<p>CONCLUSION: Applying 99Tc-MDP combined with methylprednisolone is better than methylprednisolone alone for TAO with less adverse reaction, which appears to be an effective treatment for TAO.

AIM: To compare corneal curvature and astigmatism values identified with OPD - Scan Ⅲ, lOL Master, Pentacam and KR - 8900 in cataract patients and to evaluate the consistencies and differences. METHODS: In this prospective clinical trial, 45 cataract patients (86 eyes), received treatment at the Department of Ophthalmology in our hospital from April 2017 to June 2017, underwent corneal parameters measurements with four instruments: OPD-Scan Ⅲ, Pentacam, IOL Master, and KR-8900. Measurements included corneal curvature (K1, K2, Km) and astigmatism parameters. The results were assessed using the paired samples t tests, Pearson coefficient,and Biand-Aitman plots. RESULTS: The difference of K1value measured by OPD-ScanⅢ and IOL Master was significant (P<0.001). Significant differences were also found in K2and Km values between OPD - Scan Ⅲ and Pentacam or IOL Master(P<0.05),while others had noncomparable results (P>0 05). All biometry measurements revealed good liner correlation (r=0.408-0.980, P<0.001). The Biand-Aitman showed that the corneal curvature and astigmatism vectors examined by OPD-Scan Ⅲ and Aii other devices had non-comparable results,except for the comparison of K1, K2and Kmmeasured by OPD-Scan Ⅲand KR-8900.CONCLUSION: OPD-Scan Ⅲ and KR-8900 can be interchangeable for the measurements of corneal curvature, while the others are not directly interchangeable. The astigmatic results obtained from OPD-Scan Ⅲ are not completely interchangeable with KR-8900,IOL Master or Pentacam.

Abstract?AIM: To investigate mechanism of bradykinin ( BK) on inflammations of retinal pigment epithelium ( RPE) cells.?METHODS: ARPE -19 cells were cultured in vitro, stimulated by 100nM BK for 24h. Cell morphology changes were observed by microscope, and BK receptor localization was detected through cell immunofluorescence. Changes of Ca2+in BK and BR antagonist stimuli were detected by laser scanning confocal microscopy.The expressions of COX-1, COX-2, eNOS and iNOS protein in control group and BK group were detected by Western Blot.?RESULTS: After the stimulation of BK, there was no significant changes of ARPE-19 cells in morphology.Kinin B1 receptors ( B1R ) and B2 receptors ( B2R ) could be detected in ARPE-19 cells.Compared with control group, Ca2+concentrations significantly increased in BK group; in B1R antagonist group and B2R antagonist group Ca2+concentrations increased less than BK group; B1R and B2R antagonist group showed no obvious changes in Ca2+concentrations.Compared with control group, COX-2 and iNOS protein concentrations were significantly increased in BK group (P<0.001).?CONCLUSION:BK induces the increasing expression of COX-2 and iNOS in the cultured ARPE cells through binding with either B1R or B2R.
