Abstract The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas：optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

Background/Aims: Lenvatinib resistance remains a critical barrier in advanced hepatocellular carcinoma (HCC) therapy. However, the underlying mechanisms and strategies for reversing resistance remain incompletely understood. Methods: Integrated transcriptomics of lenvatinib-resistant patient tumors and an acquired-resistance murine model identified a novel macrophage subpopulation. Functional validation employed CRISPR-SAM screening, conditioned medium (CM) assays, subcutaneous/orthotopic xenografts, patient-derived organoids (PDOs), and patient-derived xenografts (PDXs). Mechanistic studies included ChIP-qPCR, co-immunoprecipitation, and pharmacologic targeting. Clinical relevance was assessed in a retrospective cohort. Results: Resistant HCC exhibited significant enrichment of a COLEC12high TAM subset , which correlated with poor survival and treatment response. These TAMs secreted neuregulin-1 (NRG1) , activating HER2/HER3-AKT signaling in tumor cells to drive cancer stemness and lenvatinib resistance. Mechanistically, in TAMs COLEC12 sequestered STAT1 in the cytoplasm, preventing its phosphorylation, and thereby derepressing STAT3-mediated NRG1 transcription. Depletion of NRG1 reversed the stemness phenotypes and resensitized tumors to lenvatinib both in vitro and in vivo. Clinically, high NRG1 expression predicted an inferior lenvatinib response and shorter survival. Crucially, the bispecific anti-HER2/HER3 antibody zenocutuzumab restored lenvatinib efficacy in PDOs, PDXs, and murine models. Conclusions Our work establishes the COLEC12high TAM/NRG1 axis as a master regulator of therapeutic resistance and identifies NRG1 as a predictive biomarker, providing a clinically actionable strategy to overcome lenvatinib resistance in HCC.

Objective To make a comparative analysis on mechancial properties of the modified cortical bone trajectory(MCBT)nailing technique using a novel variable-diameter screw and the traditional pedicle nailing technique using the cement-augmented pedicle screw(CAPS)in the L4 vertebral body.Merthods CAPS and MCBT instrumentation in the L4 vertebral body model were established by obtaining CT scan data from osteoporotic patients.The finite element method was used to compare the stability,screw axial pull-out force and lumbar spine motion under four working conditions(upper,lower,left and right loads)by using different nailing techniques.Results The axial pull-out force of the screws in MCBT group was 25.3％higher than that of the CAPS group(P＜0.05);the load-displacement ratios of the screws in MCBT group were 14.9％(P＞0.05),23.2％(P＞0.05),and 19.1％(P＜0.05)higher than those of CAPS group under the lower,left,and right working conditions,respectively;the load-displacement ratios of the screws in MCBT group were slightly lower than those of CAPS group under the upper working condition,but the differences were not statistically significant(P＞0.05);under the anterior and posterior flexion conditions,the lumbar spine motion of MCBT group was reduced by 13.3％and 2.5％,respectively,compared with CAPS group;under the left lateral bending,right lateral bending,and axial rotational conditions,the lumbar spine motion of MCBT group was improved by 69.1％,74.6％,and 118.1％,respectively,compared with CAPS group,but these differences were not statistically significant(P＞0.05).Conclusions MCBT screw was slightly better than CAPS in axial resistance to extraction force,and stability of vertebral anterior flexion under lower,left and right working conditions,and slightly weaker than CAPS in stability under upper,left lateral bending,right lateral bending,and axial rotational conditions.This study demonstrates that MCBT screw has certain advantages over CAPS,providing a pre-basic foundation for the clinical application of MCBT nailing technique for treating osteoporosis.

Objectives:To evaluate the difference in biomechanical properties of lumbar spine between tradi-tional trajectory(TT)and modified cortical bone trajectory(MCBT)pedicle screws in different osteoporotic condi-tions using finite element analysis.Methods:CT scanning was used to obtain lumbar spinal tomographic im-ages of osteoporotic patients,and then the L4 lumbar spine structure was reconstructed in three dimensions and validated.Two nail channels were constructed by varying the bone density as osteopenia(A1),moderate osteoporosis(A2),and severe osteoporosis(A3),respectively.One was a conventional double-threaded pedicle screw used in TT with a diameter of 6mm and an overall length of 45mm(TT group),the other was a vari-able-diameter,all-cortical bone threaded pedicle screw used in MCBT with a diameter of 4-5.5mm and an overall length of 45mm(MCBT group).The effects of the two designs on screw pullout resistance,stability(load-displacement ratio of upward,downward,left and right working conditions,defined as the ratio of load value to displacement when screw tail end displaced 0.1mm upward,downward,left and right towards its vertical axis)and lumbar spine mobility(when forward flexion,backward extension,lateral bending and axial rotation)were analyzed under different osteoporotic conditions.Results:In terms of axial pullout force,the MCBT group significantly improved 93.5％,96.5％,and 98.5％than the TT group in A1,A2,and A3,respec-tively.In terms of stability,at upward,downward,left,and right working conditions,the load-displacement ratios of the screws in the MCBT group were improved in comparison with the TT group in A1,A2,and A3,respectively,by 42.2％,40.8％,41.7％;49％,49％,51.5％;82.4％,81.5％,85.2％;73.1％,70.8％,72.5％.In terms of lumbar spine mobility,at forward flexion,under A1,A2,and A3,the TT group increased by 25％,26.6％and 28.7％compared to the MCBT group,respectively;at backward extension,the TT group increased by 24.5％and 22.9％compared to the MCBT group under A1 and A2,respectively,whereas under A3,the difference was not significant(P＞0.05);at lateral bending and axial rotation,the MCBT group had a slightly slight increase compared to the TT group under A1,A2,and A3(P＞0.05).Conclusions:Under different degrees of osteoporosis grading,MCBT technique was inferior in stability to TT technique only in spinal axial rotation and lateral flexion,while it outperformed TT technique in axial pull-out force,screw stability,and spinal stability during forward flexion and backward extension.
