Objective To observe the effect of Astragalus Injection(AI) on aquaporin-1(AQP-1) expression of peritoneal mesothelial cells in rats with peritoneal dialysis.Methods Twenty-five male SD rats were divided into the normal control group(N =7),model group(N =9) and AI group(N =9).Except the normal control group,the model group was given intraperitoneal injection of peritoneal dialysate(containing glucose 42.5 g/L),and AI group was given intraperitoneal injection of peritoneal dialysate(containing glucose 42.5 g/L) plus AI(20 mg/mL),25mL/d for 10 continuous days.On the 11th day of experiment,the amount of dialysis ultrafiltration(UF) and net UF,and the concentration ratio of dialysate and plasma sodium(D/PNa) were measured,peritoneal pathological changes were observed with light microscope,and the expression of AQP-1 in peritoneal mesothelial cells was detected with immunohistochemical method.Results When the peritoneal dialysate was kept in the abdominal cavity for 60 min,the amount of UF and Net UF was increased in AI group(P

Background Ultra-long scan depth OCT can achieve imaging of full range of human ocular anterior segment.However,the measurement of the dimension of anterior segment from the OCT image with high speed and precision is a challenge at present.The software of automatic data processing is still lack in analyzing spectral domain OCT.Objective This study was to perform the automatic biometry and data processing of human ocular anterior segment OCT image by using self-developed automatic detection software and evaluate the accuracy and repeatability of this method.Methods Twenty eyes of 10 normal subjects were included in Eye Hospital of Wenzhou Medical University from June to July 2013.The OCT image of anterior eye segments were obtained with custom-made ultra-long scan depth OCT under the informed consent.Anautomatic software algorithm was developed for the biometric measurement on these OCT images,including boundary segmentation,image registration and optical correction of OCT images.The boundary segmentation algorithm utilized the axial gradient information of OCT images and the shortest path search principal based on the dynamic programming to optimize edge finding.Central corneal thickness (CCT),anterior chamber depth (ACD),pupil diameter (PD),lens thickness (LT),radius of lens anterior curvatures (LAC) and radius of lens of posterior curvatures (LPC) were automatically and manually measured,and the validity of automatic detection algorithm was assessed by calculating the intraclass correlation coefficient (ICC) between the automatic and manual measurements,and the repeatability was validated by calculating the coefficient of repeatability (COR) between repeated measurement.This study was approved by the Ethic Committee of Wenzhou Medical University and informed consent was obtained from all subjects.Results There were no significant differences in the results of CCT,ACD,PD,LT,LAC and LPC between the automatic and manual measurements (P =0.205,0.167,0.285,0.127,0.102,0.074).The results were consistent between automatic and manual measurements (all at ICC＞0.75).The repeated measurement values were consistent in CCT,ACD and LT in both automatic and manual modes (all at ICC＞0.75).The reproducibilities of automatic biometry in PD and LAC (ICC =0.793,0.872;COR =2.90,5.79) were better than those of manual mode (ICC =0.631,0.579;COR =5.62,10.46);while the reproducibility of automatic biometry in LPC (ICC =0.663;COR =6.17) was lower than that of manual mode (ICC =0.794,COR =4.79).Conclusions Self-developed automatic detection software appears to be accurate and repeatable in measuring dimension of spectral domain OCT images.This automatic software algorithm can be used for the biometry and monitor of human ocular anterior segment.

Background Tear meniscus gained by OCT device is essential to the dry eye diagnosis.Currently,RTVue Fourier-domain optical coherence tomography (FD-OCT) is commercially available to image the tear menisci.However,there were few studies to report the repeatability and reproducibility of lower and upper tear meniscus parameters measured by RTVue FD-OCT.Objective The purpose of this study was to assess the repeatability and reproducibility of lower and upper tear meniscus parameters measured by RTVue FD-OCT in normal and dry eyes.Methods In this prospective study,20 dry eyes of 20 patients were finally recruited,and 20 normal eyes of 20 age-and gender-matched healthy subjects were included during the same period.Successive three-time scans were performed at a 3-minute interval with RTVue FD-OCT in optional eye by one well-trained examiner,and the other operator performed the same measurement 10-15 minutes later.Six parameters of tear meniscus were yielded by custom software,including upper meniscus curvature (UMC),upper meniscus height(UMH),upper meniscus area (UMA),lower meniscus curvature (LMC),lower meniscus height (LMH) and lower meniscus area (LMA).The between-image repeatability was assessed using mean coefficient of repeatability (MCOR),while between-operator reproducibility were evaluated using coefficient of repeatability (COR) and interclass correlation of coefficients (ICC).Results As for the between-image repeatability,the results of MCOR for UMH,UMA,LMH and LMA were 5.11％,3.58％,4.98％ and 4.82％ respectively in the normal eyes and 5.60％,5.80％,5.03％ and 5.74％ respectively in the dry eyes.As for the between-operator reproducibility,the results of COR and ICC for UMA were 5.38％ and O.975,the COR and ICC for LMA were 5.28％ and 0.961 respectively in the normal eyes,and the results of COR and ICC for LMA were 9.69％ and 0.964 in the dry eyes.Conclusions The UMA,LMH and LMA tear meniscus parameters obtained by RTvue FD-OCT show good between-image repeatability,and LMA also presents good between-operator reproducibility.Measurement of tear meniscus parameters with RTVue FD-OCT measuring is a potential diagnostic index for the diagnosis of dry eye.
