Work serves as a critical means of obtaining resources, facilitating personal growth, realizing self-worth, and engaging in social interactions. However, work-related diseases pose significant threats to workers’ health and productivity, and impose considerable economic burdens. This article categorized work-related diseases into six major types, including musculoskeletal disorders, mental and behavioral disorders, cardiovascular and metabolic diseases, digestive system diseases, reproductive system diseases, and non-specific respiratory diseases, and summarized their risk factors, assessment methods, policy regulation, and prevention and control measures. Current research in this field predominantly relies on cross-sectional studies, which present limitations in causal inference and potential risks of bias. Future studies should expand sample sizes, optimize research designs, and establish multidimensional evaluation systems to comprehensively assess the health and economic impacts of work-related diseases. It is recommended to enhance the translation of research findings into practice, thereby providing a scientific basis for the occupational health protection system and promoting the well-being and sustainable development of the working population.

Adaptive optics(AO)is a technology designed to enhance the performance of optical systems through real-time measurement and correction of optical aberrations. With continuous advancements in refractive surgery techniques and rising patient expectations for surgical outcomes, the precise implementation of personalized refractive corrections has become a critical focus. The integration of AO technology into refractive surgery provides novel technical support. Specifically, the adaptive optics vision simulator(VAO)facilitates accurate preoperative objective and subjective refraction by dynamically measuring and correcting ocular wavefront aberrations, thereby improving refractive efficiency. Additionally, it enables effective prediction of postoperative aberrations for personalized procedures, assists clinicians in making data-driven preoperative decisions, facilitates comparative analysis of different surgical techniques, and allows intuitive evaluation of postoperative visual quality. This review comprehensively examines the advances in VAO applications for refractive surgery and analyzes both its clinical advantages and technical limitations.

Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe₃O₄ loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4⁺/CD8⁺ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.

With the accelerating process of population aging, binocular vision disorders have become increasingly prevalent, posing new challenges for both social aging strategies and ophthalmic clinical practice. Non-strabismic binocular vision anomalies(NSBVAs)are notably prevalent among elderly populations; however, current research predominantly focuses on the abnormality rates derived from individual binocular vision clinical tests, while data on the actual prevalence based on comprehensive diagnostic criteria remain limited. This review synthesizes existing scientific literature to provide a concise yet comprehensive overview of the prevalence, risk factors, and clinical diagnostic methods of NSBVAs in pre-presbyopic and presbyopic populations, with an in-depth examination of age-related changes in binocular vision function among older adults. By integrating and comparing analyses of the correlations between age and various binocular vision parameters, this review aims to enhance understanding of age-related binocular vision dysfunction and establish a theoretical foundation for developing targeted diagnostic and therapeutic approaches. Ultimately, these insights could contribute to improved visual performance and life satisfaction in elderly individuals.

Objective : To investigate the effectiveness of an extraoral guide plate system targeting the superior and inferior heads of the lateral pterygoid muscle in improving the accuracy of injection therapy for anterior disc displacement (ADD) of the temporomandibular joint (TMJ) with lateral pterygoid myalgia, and to provide a reference for precise clinical treatment. Methods: With approval from the institutional medical ethics committee and informed consent from patients, spiral CT scans were performed on seven patients with ADD accompanied or not accompanied by lateral pterygoid myalgia to acquire craniofacial data. Mimics 21.0 software was used to reconstruct three-dimensional craniofacial structures, identify attachment points of the superior and inferior heads of the lateral pterygoid muscle, and design dual injection paths along with a retention system. Personalized templates were fabricated using digital light procession-based 3D printing. Under the guide plate, a single targeted injection of 20 U of botulinum toxin type A (BTX-A) was administered into both the superior and/or inferior heads of the lateral pterygoid muscle. Immediate postoperative CT scans were conducted to compare actual needle placement with preoperative plans. Pain was assessed using the visual analogue scale (VAS) at 3 days and 1, 2, and 4 weeks postoperatively. Joint clicking was recorded at 2 and 4 weeks, and complications were monitored throughout the duration of the study. Results : A total of 15 sites in 7 patients were injected into the upper / lower head of the lateral pterygoid muscle under the guidance of the guide plate. Under the guide plate, all of the injections achieved an angular deviation within 2.5° (superior head: 2.49° ± 0.17°, inferior head: 2.31° ± 0.16°) and a needle tip positional deviation within 2 mm [superior head: (1.96 ± 0.25) mm, inferior head: (1.65 ± 0.21) mm]. The significant pain improvement rate (defined as ≥3-point reduction in VAS score) increased from 60% (9/15) at day 3 to 85% (13/15) at 2 weeks post-operation, stabilizing at 86.7% (13/15) at 4 weeks post-operation. Joint clicking improvement rates reached 72% (11/15) at 2 weeks post-operation and 75% (11/15) at 4 weeks post-operation. Regarding safety, only one case of injection site swelling and one case of transient paresthesia were observed; both resolved spontaneously within a short period of time. No neurovascular injury events occurred. Conclusion CT-guided guide plate achieves precise targeting design to minimize injection errors in the lateral pterygoid muscle. This technology is effective and safe, and it can provide an anatomically specific and operationally versatile targeted therapy for temporomandibular disorders.

BACKGROUND: Knee osteoarthritis (OA) is still challenging to prevent or treat. Enhanced endoplasmic reticulum (ER) stress and increased pyroptosis in chondrocytes may be responsible for cartilage degeneration. This study aims to investigate the effect of ER stress on chondrocyte pyroptosis and the upstream regulatory mechanisms, which have rarely been reported. METHODS: The expression of the histone methyltransferase enhancer of zeste homolog 2 (EZH2), microRNA-142-3p (miR-142-3p), and high mobility group box 1 (HMGB1) and the levels of ER stress, pyroptosis, and metabolic markers in normal and OA chondrocytes were investigated by western blotting, quantitative polymerase chain reaction, immunohistochemistry, fluorescence in situ hybridization, fluorescein amidite-tyrosine-valine-alanine-aspartic acid-fluoromethyl ketone (FAM-YVAD-FMK)/Hoechst 33342/propidium iodide (PI) staining, lactate dehydrogenase (LDH) release assays, and cell viability assessments. The effects of EZH2, miR-142-3p, and HMGB1 on ER stress and pyroptosis and the hierarchical regulatory relationship between them were analyzed by chromatin immunoprecipitation, luciferase reporters, gain/loss-of-function assays, and rescue assays in interleukin (IL)-1β-induced OA chondrocytes. The mechanistic contribution of EZH2, miR-142-3p, and HMGB1 to chondrocyte ER stress and pyroptosis and therapeutic prospects were validated radiologically, histologically, and immunohistochemically in surgically induced OA rats. RESULTS: Increased EZH2 and HMGB1, decreased miR-142-3p, enhanced ER stress, and activated pyroptosis in chondrocytes were associated with OA occurrence and progression. EZH2 and HMGB1 exacerbated and miR-142-3p alleviated ER stress and pyroptosis in OA chondrocytes. EZH2 transcriptionally silenced miR-142-3p via H3K27 trimethylation, and miR-142-3p posttranscriptionally silenced HMGB1 by targeting the 3'-UTR of the HMGB1 gene. Moreover, ER stress mediated the effects of EZH2, miR-142-3p, and HMGB1 on chondrocyte pyroptosis. In vivo experiments mechanistically validated the hierarchical regulatory relationship between EZH2, miR-142-3p, and HMGB1 and their effects on chondrocyte ER stress and pyroptosis. CONCLUSIONS A novel EZH2/miR-142-3p/HMGB1 axis mediates chondrocyte pyroptosis and cartilage degeneration by regulating ER stress in OA, contributing novel mechanistic insights into OA pathogenesis and providing potential targets for future therapeutic research.

Objective:To observe the effect of different degrees of decentration and tilt on the optical quality of the intraocular lenses (IOLs) with different focus designs.Methods:The UV 3300 PC UV-visible spectrophotometer was employed to measure the spectral transmittance of the monofocal IOL CT ASPHINA 509M (509M), bifocal IOL AT LISA 809M (809M), and trifocal IOL AT LISA Tri 839MP (839MP) within Zeiss MICS platform with a refractive power of + 20 D. The modulation transfer function (MTF) values at a spatial frequency of 50 lp/mm along with MTF curves and United States Air Force (USAF) resolution test charts for each IOL at the focal point were measured at apertures of 3.0 mm and 4.5 mm using the in vitro optical quality testing system OptiSpheric IOL R&D under centered, decentered (0.3, 0.5, 0.7, 0.9 and 1.1 mm) and tilted (3°, 5°, 7°, 9° and 11°) conditions. Results:All three IOLs filtrated the ultraviolet (UV) spectrum below 400 nm.When each IOL was in the centered position, at the 3.0 mm aperture, the MTF values were 0.772 at the far focus of the monofocal IOL 509M, 0.467 and 0.282 at the far and near focus of the bifocal IOL 809M, and 0.416, 0.147, and 0.229 at the far, intermediate, and near focus of the trifocal IOL 839MP, respectively.Whereas at the 4.5 mm aperture, the monofocal IOL 509M MTF value at the far focus was 0.664, the bifocal IOL 809M MTF values at the far and near focus were 0.506 and 0.264, and the trifocal IOL 839MP MTF values at the far, intermediate, and near focus were 0.392, 0.107, and 0.210, respectively.Among the three centered IOLs, the 509M demonstrated the highest MTF value at the far focus, followed by the 809M and then the 839MP; at the near focus, the MTF value of the 809M surpassed that of the 839MP.For decentration and tilt, the difference in MTF values of the three IOLs at the far and near focus was consistent with the differences observed when they were centered.At the same degree of decentration and tilt, all three IOLs exhibited superior optical quality at the 3.0 mm aperture compared to the 4.5 mm aperture.The optical quality of all three IOLs exhibited an overall decline as decentration and tilt increased.All three IOLs demonstrated a decrease in optical quality at the decentration of 0.3 mm or the tilt of 5°.Conclusions:The IOLs within the Zeiss MICS platform design exhibits identical spectral transmittance and UV filtering properties.Among the three IOLs, when centered, the 509M, the 839MP, and the 809M exhibit superior optical quality at the far, intermediate, and near focal points, respectively.Under decentered and tilted conditions, the 509M and the 809M demonstrate better resistance against decentration and tilt, respectively, at both far and near focuses.Additionally, all three IOLs demonstrate better optical quality at smaller apertures, given equivalent degrees of decentration or tilt.However, the optical quality at each focal point of the three IOLs decreases compared to the centered position when subjected to a decentration of 0.3 mm or a tilt of 5°.
