Background Measurement of corneal thickness is of great significance for the design of refractive surgery and the diagnosis of eye diseases,measuring equipments and technology develop rapidly in recent years.Optovue iVue OCT is a new frequency-domain optical coherence tomography (OCT),to compare its results with those of Pentacam and Visante OCT is helpful to objectively assess the clinical value of Optovue iVue OCT.Objective This study was to investigate the repeatability of corneal thickness measurement with Optovue iVue OCT and the comparatbility with Pentacam three-dimensional anterior segment analysis diagnostic system and Visante OCT.In addition,this study attempted to analyze the distribution of average corneal thickness in each quadrant by Optovue iVue OCT.Methods The corneal thicknesses of the corneal thinnest point,the central point and 3:00,6:00,9:00,12:00 zones 1 mm away from the center of the cornea were measured in 45 right eyes of 45 subjects with myopia using Optovue iVue OCT,Pentacam and Visante OCT in Tianjin Eye Hospital.Interclass correlation coefficient (ICC) was used to analyze the repeatability of measurement by Optovue iVue OCT.The agreements between Optovue iVue OCT and Pentacam or Visante OCT were evaluated by Bland-Altman test.The corneal area of 1.0-2.5 mm away from the center was divided into eight quadrants and the average corneal thickness of each quadrant was measured and analysis with Optovue iVue OCT.Results No significant difference was found in corneal thickness values for 3 times by Optovue iVue OCT (P=0.546).The ICC by Optovue iVue OCT was 99.92%,99.99%,99.96%,99.99%,99.99% and 99.97% at the corneal thinnest point,the central point and 3:00,6:00,9:00,12:00 zones respectively.There were significant differences among the 3 kinds of methods (P =0.000,0.001,0.000,0.003,0.002,0.000).The measured values of Optovue iVue OCT were significantly lower mean 24.20 μm than those of Pentacam (P=0.000,0.001,0.000,0.003,0.004,0.000),but only the value at 12:00 zone of Optovue iVue OCT was evidently declined in comparison with that of Visante OCT (P =0.016),there were no significant differences between all the other zones (P =1.000,0.447,0.239,1.000,1.000).While the mean corneal thickness value from Pentacam lowed by 14.01 μm in comparison with Visante OCT,all zones had significant differences (P =0.009,0.005,0.034,0.017,0.008) except the central point (P =0.056).Based on the Optovue iVue OCT,the thinnest zone was at temporal quadrant in 23 eyes (accounting for 51.11%) and at superior quadrant or super nasal quadrant in 21 eyes (both at 46.66%).Conclusions Optovue iVue OCT measurement of corneal thickness is of high repeatability and is consistent with Visante OCT in myopic eye.Optovue iVue OCT shows evident difference from Pentacam in the measurement of corneal thickness.The thinnest point of the cornea is mainly in the inferior temporal quadrant and the thickest point is commonly in superior quadrant and nasal superior quadrant based on Optovue iVue OCT.

Objective To explore the diagnostic value of three-dimensional ultrasound parameters-vascularity index (VI) and the volume of kidney in chronic kidney disease (CKD). Methods A total of 80 CKD patients at different stages and 30 healthy adults were enrolled in the study. VI and the renal volume were calculated with three-dimensional ultrasound, while resistance index (RI), cortical thickness (CT) and the volume of kidney were calculated with two-dimensional ultrasound, and the correlation of those parameters were analyzed statistically. Results VI of CKD2 patients reduced significantly compared with the control group, and RI of CKD3 patients increased significantly, CT of CKD3 patients reduced significantly. The diagnostic sensitivity, specificity and diagnostic value of VI in patients with early and late CKD were all higher than thpse of RI. Compared with the control group, three-dimensional ultrasound of renal volume and two-dimensional ultrasound volume of CKD 1 patients increased significantly, three-dimensional ultrasound volume of CKD2 patients reduced significantly, and two-dimensional ultrasound volume of CKD4 patients reduced significantly. There was significant negative correlation among VI, three-dimensional ultrasound volume, CT, two-dimensional ultrasound volume and pathological change scoring (r=-0.67, -0.52, -0.43, -0.52). Conclusion VI and three-dimensional ultrasound volume can detect renal function damage more earlier and sensitively than RI and two-dimensional ultrasound volume.

Objective:To compare the fit of Co-Cr basal crowns fabricated by three kinds of technology. Methods:18 laser cured resin dies were divided into A, B and C groups(n=6) randomly. Co-Cr basal crowns of group A, B and C were made by traditional casting technology, CAD/CAM cutting metal technology and direct metal laser sintering technology( DMLS) respectively. The crowns were cemented to the corresponding dies and the basal crowns and dies were embedded in methyl acrylic. The thickness of the cement layer of the samples was measured under a stero microscope. Data were analyzed with SPSS13. 0 statistical software. Results:Marginal gap of group A, B and C was (66.08 ±3.90) μm, (29.21 ±3.31) μm and (24.96 ±2.99) μm respectively(P<0.01). Internal gap of group A, B and C was (114. 10 ± 27. 66) μm, (73. 69 ± 31. 31) μm and (79. 89 ± 33. 63) μm respectively(A vs B or C, P<0. 01, B vs C, P>0. 05). Conclusion:DMLS technology may make the best marginal fit, CAD/CAM and DMLS technology may pro-duce better internal fit. The marginal fit and the internal fit of the crowns prepared by the 3 methods can meet the clinical requirements.

OBJECTIVE To analyze the effect of advanced glycation end products(AGEs) on apoptosis of cultured mouse spiral ganglion cells(SGCs) and expression of receptor of AGEs(RAGE). To explore the pathway of AGEs in promoting apoptosis of SGCs. And to explore the possible mechanism of neural presbycusis. METHODS The effect of AGEs on apoptosis of SGCs was studied by Tunel technique and fluorescence microscope. The expression of RAGE mRNA was assayed by Real time RT-PCR. RESULTS AGEs induced apoptosis of cultured SGCs. The effects were dose-dependent and time-dependent. Meanwhile RAGE mRNA expression was enhanced in apoptosis cells. CONCLUSION AGEs induced apoptosis in SGCs,which may be mediated by RAGE. And this may be one of the mechanisms of neural presbycusis.

Objective To study the wavelet entropy of intracranial electrode recording electroencephalogram (EEG) during the seizure onset,and explore the prospect of applying it for automatic detection of EEG.Methods Twenty-eight seizure events of 9 epilepsy patients whose outcome were Engel class Ⅰ were retrospective analyzed,by comparing the pre-ictal,initial ictal and ictal wavelet energy entropy variations of both seizure onset zone (SOZ) contacts and non-SOZ contacts.Results The wavelet energy entropy of SOZ contacts increased from pre-ictal (0.053 ± 0.047 ) to initial ictal (0.326 ± 0.250),while it declined during the ictal (0.138 ± 0.097,F =30.904,P =0.000).There was no obvious change of the wavelet energy entropy of non-SOZ contacts in different periods.By further applying time-window wavelet entropy to the detection of intracranial EEG,the results showed that the time-window wavelet energy entropy could be sensitive to reflect the seizure onset time and electrodes.Conclusion The wavelet energy entropy of contacts inside SOZ increased significantly at scizurc onset,and this conclusion can be used to assist in presurgical localization of epilepsy.
