Bruch's membrane opening(BMO)is the true anatomical border of the optic nerve head and provides higher anatomical accuracy, structural stability and measurement repeatability than traditional assessments based on the clinically visible optic disc margin. Optical coherence tomography(OCT)serves as a key technical tool for quantitative assessment of BMO-associated structural parameters. With the development of spectral-domain OCT(SD-OCT)and swept-source OCT(SS-OCT), parameters such as BMO-minimum rim width(BMO-MRW), BMO-minimum rim area(BMO-MRA), BMO area, offset, tilt, and torsion have emerged as important imaging biomarkers for evaluating optic nerve head morphology and for assisting in the diagnosis, staging, and longitudinal monitoring of glaucoma, myopia, and pathological myopia. Traditionally, the acquisition of these parameters has relied heavily on manual segmentation, which is limited by low efficiency, strong subjectivity, and considerable inter-observer variability. In recent years, artificial intelligence has been increasingly applied to OCT image segmentation, quality control, cross-device calibration, and automated quantitative analysis, thereby improving efficiency, objectivity, and reproducibility, particularly in eyes with complex optic disc morphology. This review summarizes recent advances in the BMO-related terminology standardization, imaging and quantitative methodologies, quality control,artificial intelligence-assisted analysis, as well as clinical evidence of its application in glaucoma, myopia and pathological myopia. Particular emphasis is placed on their potential value in the differential diagnosis and follow-up evaluation of highly myopic eyes with glaucoma, aiming to provide a reference for the standardized clinical application and future translational use of BMO-related parameters.

Pediatric urological non-Hodgkin lymphoma is relatively rare.When a single renal or ureteral tumor with multiple lymph node or bone metastases is present, it is very easy to be misdiagnosed as urinary tumor with metastasis, resulting in unnecessary radical nephrectomy. This paper reports two cases of non-Hodgkin lymphoma presenting with single urinary nodules. Case 1 was diagnosed with a 4.5cm tumor in the right kidney due to fever and fatigue. CT and PET-CT showed multiple bone destruction and lymph node metastasis. Renal biopsy was performed and ALK-positive anaplastic large cell lymphoma was diagnosed. Chemotherapy was effective for 6 months. Case 2 was diagnosed with left hydronephrosis due to intermittent low back pain for 2 weeks. Ultrasound examination revealed ureteral dilation with left hydronephrosis and low echo occupying of the lower ureter. The patient had sudden blurred vision before surgery. MRI examination revealed space occupying in the right optic nerve frame, and PET-CT found multiple bone, lymph nodes and nerve invasion. A lymph node biopsy was performed and Burkitt lymphoma was diagnosed. After 6 months of chemotherapy and radiotherapy, the tumor shrank significantly.

Objective:To preliminarily establish a valuable threshold for the college students’ psychological Suzhi questionnaire simplified version (CSPSz-SV) by means of the latent profile analysis and the receiver operating characteristic(ROC) curve.Methods:The CSPSz-SV was applied to investigate 1 870 college freshmen from undergraduate colleges. The identification threshold value of the CSPSz-SV was identified by combining latent profile analysis (LPA) and the ROC curve.Both Mplus 8.3 and R 4.3.1 software were used for the data analysis.Results:Based on LPA results, the college freshmen were divided into three categories according to the levels of psychological Suzhi: the low psychological Suzhi group, the medium psychological Suzhi group, and the high psychological Suzhi group.Following the LPA, the ROC analysis was conducted to obtain the optimal critical value (91) of the psychological Suzhi level for college freshmen (Youden's index was 0.934, sensitivity was 0.979, specificity was 0.955, positive predictive value was 0.855, negative predictive value was 0.994, accuracy was 0.960, and AUC was 0.991, respectively). College freshmen were divided into the abnormal psychological Suzhi group and the normal psychological Suzhi group in accordance with this critical value, and the difference between the two groups was statistically significant (Cohen's d=1.74-2.18, P<0.001). Conclusion:The threshold value established and obtained in this study can be reviewed as a reference for evaluating the psychological Suzhi level of college freshmen.
