Background Optical Quality Analysis System II （OQAS, Visiometrics, Terrassa, Spain） that uses double-pass （DP） technique is the only commercially available device that allows objective measurement of ocular retinal image quality. This study aimed to evaluate the impact of spectacle lenses on the ocular optical quality parameters and the validity of the optometer within OQAS. Methods Seventy eyes of healthy volunteers were enrolled. Optical quality measurements were performed using OQAS with an artificial pupil diameter of 4.0 mm. Three consecutive measurements were obtained from spectacle correction corresponding to subjective refraction and from the OQAS built-in optometer separately. The modulation transfer function cutoff frequency, the Strehl ratio, the width of the point spread function （PSF） at 10% of its maximal height （PSF10）, and the width of the PSF at 50% of its maximal height （PSF50） were analyzed. Results There was no significant difference in any of the parameters between the spectacle correction and the optometer correction （all P 〉0.05, paired t-test）. A good agreement was found between both the methods and a good intraobserver repeatability in both the correction methods. Difference in best focus between two methods was the only parameter associated significantly with optical quality parameter differences. Best focus difference, built-in optometer correction with or without external cylindrical lens, and age were associated significantly with PSF10 difference. No linear correlation between refractive status and optical quality measurement difference was observed. A hyperopic bias （best focus difference of （0.50±0.44） D） and a relatively better optical quality using spectacle correction in high myopia group were found. Conclusions OQAS based on DP system is a clinically reliable instrument. In patients with high myopia, measurements using built-in optometer correction should be considered and interpreted with caution.

Background:As a novel blocker of vascular endothelial growth factor receptor (VEGFR), fruquintinib has been approved for treating colorectal cancer (CRC). However, its dosage and therapeutic efficacy are limited by its widespread adverse reactions. Venetoclax, recognized as the initial inhibitor of B-cell lymphoma protein 2 (BCL2), has shown potential in boosting the effectiveness of immunotherapy against CRC. This study investigated the efficacy and mechanisms of fruquintinib combined with venetoclax in treating CRC.Methods and Materials:We developed a colon cancer mouse model with the CT26 colon cell line to demonstrate fruquintinib and venetoclax's efficacy against tumors. Then we employed various techniques to evaluate different aspects of the experimental outcomes. Immunohistochemistry was used to detect cell proliferation and angiogenesis in tumor tissues. Western blot analysis was utilized to examine the occurrence of cell apoptosis, and flow cytometry to quantitate immune cells within the tumor tissues. Moreover, immunofluorescence was employed to measure cytokine levels.Results:The strongest inhibition on tumor growth was achieved by the combination of fruquintinib with venetoclax, as opposed to individual drug use. Venetoclax was found to amplify the impact of fruquintinib, leading to decreased cancer cell proliferation, increased cancer cell apoptosis, lowered angiogenesis, better vascular structure normalization, and improved immune cell infiltration.Conclusion:Our findings indicate that the addition of venetoclax enhances the impact of fruquintinib on vascular normalization and modulation of the tumor immune microenvironment. Our study presents the justification for utilizing the fruquintinib and venetoclax combination in treating CRC. Venetoclax holds promise in being assimilated into anticancer medications for CRC.

The subchannel analysis method is one of the most crucial transient safety analysis methods in the thermal design of nuclear reactors. The nonuniformity of circumferential heat transfer is slight in conventional pressurized water reactor (PWR)cores, but it is significant in advanced reactors with wire-wrapped or helical fuel rods. Predicting circumferentially nonuniform heat transfer behavior can be challenging owing to the complex geometry of helical fuel rods. In this study, a general circumferentially nonuniform heat transfer fuel rod (GCNF) model is developed to predict the fuel central temperature and circumferential heat flux and wall temperature. This model incorporates a refined two-dimensional fuel conduction model and circumferential nonuniform shape factor, addressing the dual factors contributing to the circumferential nonuniformity of helical fuel rods. An empirical correlation for the nonuniform shape factor is developed based on the computational fluid dynamics (CFD) results, and it is implemented to the subchannel code. The newly developed model is applied to a helical fuel annulus and validated by comparing the prediction results with CFD data. The maximum wall temperature predicted by the code is 1.15°C lower than the value calculated through CFD. In terms of the heat flux, the maximum value at the inner corner is22 kW lower than that obtained from the CFD prediction. The accurate prediction of circumferentially nonuniform heat transfer in helical fuel, concerning the surface heat flux and cladding temperature, addresses existing shortcomings in helical fuel subchannel analysis methods. Additionally, the capability to predict the fuel central temperature is essential for the safety analysis to determine whether fuel rods are melting. The generality of the model framework allows it to be used for the prediction of circumferential nonuniform heat transfer behavior in other types of fuel assemblies.

目的评价不同临床经验医师应用晶状体混浊分级系统(Lens Opacity Classification System Ⅲ,LOCSⅢ),基于裂隙灯及数码照片进行晶状体混浊程度评分的一致性。方法从邯郸眼病研究5 a随访项目中,随机选取2012年11月至2012年12月现场调查受试者51人(102眼)。首先由受过LOCSⅢ评分培训的高年资眼科副主任医师(评分员A)于现场参照LOCSⅢ标准图片,在裂隙灯下对晶状体核混浊程度(nuclear opacity,NO)、核颜色(nuclear color,NC)、皮质性白内障(cortical cataract,C)、后囊膜下白内障(posterior subcapsular cataract,PSC)进行评分,随后采集晶状体数码照片。评分员A和1名眼科住院医师(评分员B)根据晶状体数码照片独立进行NO、NC、C、PSC评分。然后一位经过LOCSⅢ晶状体评分培训的白内障专业副主任医生对评分员B进行培训,同时与评分员A进行讨论并统一对LOCSⅢ标准评分方法的理解后,评分员B进行第2次评分。均采用组内相关系数(intraclass correlation coefficient,ICC)分别检验评分员A基于裂隙灯及数码照片的LOCSⅢ晶状体评分的一致性,评分员B培训前、后的LOCSⅢ晶状体评分的一致性,以及评分员B培训前、后的LOCSⅢ晶状体评分与评分员A基于裂隙灯及数码照片的LOCSⅢ晶状体评分进行一致性检验。结果评分员A基于现场裂隙灯和晶状体数码照片的LOCSⅢ晶状体评分的ICC分别为:NO 0.89、NC 0.89、C 0.90、PSC0.65;评分员B培训前、后LOCSⅢ晶状体评分ICC分别为:NO 0.90、NC 0.90、C 0.89、PSC 0.12;评分员B培训前、后基于数码照片与评分员A基于裂隙灯的LOCSⅢ晶状体评分ICC分别为NO 0.77、0.82,NC 0.79、0.85,C 0.77、0.89,PSC 0.05、0.46;评分员B培训前、后与评分员A基于数码照片的LOCSⅢ晶状体评分比较ICC分别为:NO 0.83、0.81,NC 0.80、0.84,C 0.76、0.88,PSC 0.26、0.85。结论眼科临床经验对临床医师采用LOCSⅢ进行NO、NC、C评分影响不大,对PSC评分影响较大,而LOCSⅢ标准评分方法培训可以弥补眼科医师临床经验的不足,但不能提高基于裂隙灯和数码照片的LOCSⅢ对PSC评分的一致性。
