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.

Retinal vein occlusion(RVO)is the second most common blinding retinal vascular disease, and its secondary macular edema(ME)is an important cause of visual function impairment in patients. Intravitreal injection of anti-vascular endothelial growth factor(VEGF)drugs serves as the first-line treatment, yet it is confronted with such issues as the need for repeated injections and non-response in some patients. Imaging and laboratory biomarkers play a crucial role in the early accurate diagnosis, prediction of disease progression, and evaluation of visual prognosis of RVO-ME. This study systematically reviews the research progress of imaging and laboratory biomarkers related to the prognosis of RVO-ME after anti-VEGF treatment in recent years, covering imaging biomarkers like central retinal thickness and ellipsoid zone integrity, as well as laboratory biomarkers such as serum APLN and aqueous humor IL-6. It summarizes the associations between different biomarkers and the prognosis of anti-VEGF therapy, aiming to provide a basis for the early accurate assessment and optimization of individualized treatment for RVO-ME patients, which holds significant clinical reference value.

OBJECTIVE: To observe the effect of electroacupuncture combined with enhanced recovery after surgery (ERAS) protocol on promoting intestinal function in patients after gastric cancer surgery. METHODS: Forty-four patients who underwent radical gastrectomy for gastric cancer were randomly divided into an experimental group (22 cases, 3 cases were excluded) and a control group (22 cases, 4 cases were excluded). Both groups received treatment under ERAS protocol, the experimental group was given electroacupuncture at bilateral Neiguan (PC6), Hegu (LI4), Zusanli (ST36) and Quchi (LI11), disperse-dense wave was selected, with frequency of 2 Hz/100 Hz. The control group received placebo electroacupuncture intervention, with the same acupoints as the experimental group, electrode pads were placed on the acupoints without electrical stimulation. Each session lasted 30 min, starting from 1 h after surgery, once every 24 h, until the patient resumed anal flatus. The intestinal sound rate of both groups was observed 24 h before surgery and 24, 48 h after surgery. The bowel sound recovery time (BSRT), time to first anal flatus, time to first defecation, and tolerance to oral enteral nutrition suspension were compared between the two groups. The levels of serum C-reactive protein (CRP), interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured 24 h before surgery and 24 h after surgery in both groups. RESULTS: The intestinal sound rate 24 h after surgery was decreased compared with that 24 h before surgery in the two groups (P<0.05), the intestinal sound rate 24, 48 h after surgery in the experimental group was higher than that in the control group (P<0.05). The BSRT in the experimental group was earlier than that in the control group (P<0.05) .The levels of serum CRP, IL-6, IL-10 24 h after surgery in the experimental group were higher than those 24 h before surgery (P<0.05), while the levels of serum CRP, IL-4, IL-6, IL-10, IFN-γ in the control group were higher than those 24 h before surgery (P<0.05); the levels of serum CRP、IL-4、IFN-γ 24 h after surgery in the experimental group were lower than those in the control group (P<0.05) .The tolerance rate of oral enteral nutrition suspension in the experimental group was 84.2% (16/19), which was higher than 50.0% (9/18) in the control group (P<0.05). CONCLUSION Electroacupuncture combined with ERAS protocol can improve the intestinal motility, shorten the BSRT, enhance the tolerance of oral intake, and reduce inflammatory response in patients after gastric cancer surgery.

Prolonged disorders of consciousness (pDoC) represent severe complications following severe traumatic brain injury, imposing substantial burden on both families and the society. Currently, the diagnosis and treatment of pDoC still face challenges, including insufficient assessment accuracy and limited efficacy of arousal therapies. On one hand, innovative approaches such as neuroimaging, electrophysiological techniques, and neuromodulation have provided new directions for the diagnosis and treatment of pDoC, yet standardized diagnostic and therapeutic protocols as well as large-scale clinical evidence remain lacking. On the other hand, standardized management of pDoC requires multidisciplinary collaboration, yet the limited number of specialized arousal centers in China hinders the provision of systematic therapy. The Department of Neurosurgery at West China Hospital, Sichuan University has established a comprehensive pDoC care system through a multidisciplinary team approach. To this end, the authors systematically summarized the clinical exploration and advancements in pDOC arousal therapy by West China Hospital′s neurosurgical team, aiming to provide valuable insights for domestic peers and jointly advance the optimization and advancement of pDoC diagnosis and treatment.

Objective This study aimed to develop an automated method for syndrome element differenti-ation in Traditional Chinese Medicine(TCM).Methods We first constructed and trained an Instruction-tuned Multi-Task TCM text embedding model(Instr-MT-TCM)using four distinct TCM task datasets,including domain knowledge,synonymous terminology,syndrome differentiation and treatment,and TCM case labels.Subsequently,five TCM diagnostics experts holding master's degrees or higher were organized to screen a real-world TCM case dataset and annotate symptoms and signs.The purpose was to evaluate the F1-score of the proposed method—the combination of Instr-MT-TCM and a Large Language Model(LLM)—by comparing its performance against the manual annotation result on the syndrome element differentiation task.Finally,to validate its feasibility in real-world clinical settings,the method was applied to 48 prostate cancer cases to calculate the syndrome element scores.Results The Instr-MT-TCM model showed rapid performance improvement in its early training phase,achieving a Recall@1(R@1)of 0.848.Experts curated a dataset of 1,793 real-world clinical cases,covering 34 common diseases and 66 syndrome patterns.In the syndrome element differentiation task,the collaborative framework of LLM and Instr-MT-TCM achieved a mean F1-score of 0.927,outperforming the 0.512 from manual annota-tion.The syndrome element analysis revealed that the predominant elements of disease nature were fire(heat)and yin deficiency,while the main elements of disease location were bladder and kidney.Conclusion This study proposes and validates a novel method for automated TCM syndrome element dif-ferentiation based on the synergy between LLM and our custom Instr-MT-TCM model.Achieving a high F1-score(0.927)on real-world data,the method demonstrates excellent accuracy and generalization ability.Its application in prostate cancer analysis highlights its significant clinical potential,offering effective technical support,and a new research direction for intelligent TCM syndrome element differentiation.

Objective To investigate the effects of DNA Cross-Link Repair 1A(DCLRE1A)on mitochondrial func-tion in lens epithelial cells(LECs).Methods Thirty eyes from 30 patients with age-related cataracts(ARC)were select-ed and divided into three groups:cortical type(ARCC group),nuclear type(ARNC group),and posterior subcapsular type(ARPC group),with 10 cases in each group.Additionally,10 eyes from 10 age-matched patients diagnosed with epiretinal membrane and having clear lenses were selected as the control group.Western blot was used to detect the ex-pression levels of DCLRE1A protein in the anterior capsule tissues of patients in each group and in the lens epithelial cell line(SRA01/04)treated with hydrogen peroxide(H2O2)in vitro and overexpressed DCLRE1A model(OE-DCLRE1A group).The effects of overexpressed DCLRE1A on the expression levels of mitochondrial transcription factor(TFAM)and peroxisome proliferator-activated receptor-γ coactivator-1α(PGC1α)proteins were also detected.Normal cultured SRA01/04 cells were randomly divided into Control group(untreated),H2 O2 group,H2 O2+HA group(transfected with control plasmid HA),and H2O2+OE-DCLRE1A group(transfected with DCLRE1A plasmid).RT-PCR was used to measure mtD-NA expression in each group cells.Changes in mitochondrial membrane potential(MMP)and mitochondrial reactive oxy-gen species(ROS)in each group were detected by immunofluorescence staining.Results Western blot analysis showed that compared with the control group cells,the relative expression levels of DCLRE1A protein in the anterior capsule tis-sues of patients in the ARCC,ARNC,and ARPC groups were all decreased,with statistically significant differences(all P＜0.001).In the in vitro H2O2-induced oxidative damage model,compared with the Control group,the relative expression level of DCLRE1A protein in the H2O2 group was significantly decreased(P＜0.001).The overexpression efficiency results of DCLRE1A showed that,compared with the Control group,the relative expression level of DCLRE1A protein in the OE-DCLRE1A group cells was significantly increased,with statistical significance(P＜0.001).RT-PCR results showed that compared with the H2O2+HA group,the expression level of mtDNA in the H2O2+OE-DCLRE1A group was significantly in-creased(P＜0.001).Western blot analysis showed that compared with the H2O2+HA group,the relative expression levels of TFAM and PGC1α proteins in the H2O2+OE-DCLRE1A group were significantly increased(P＜0.001).Immunofluores-cence staining results showed that compared with the H2O2+HA group,the MMP level in the H2O2+OE-DCLRE1A group was significantly restored,and the accumulation of mitochondrial ROS was reduced(P＜0.001).Conclusion Under H2O2-induced oxidative stress conditions,DCLRE1A promotes the repair of damaged mtDNA in LECs by regulating mito-chondrial biogenesis,thereby reducing LEC apoptosis and participating in the occurrence and development of ARC.

Oxidative stress and its closely related pathophysiological processes of vascular damage and inflammation have been recognized as important pathogenic mechanisms in many ocular diseases.Kaempferol, a natural flavonoid compound, exhibits great promise in preventing and treating various eye disorders due to its potent antioxidant, anti-inflammatory, and anti-angiogenic activities.In dry eye models, kaempferol effectively suppresses ocular surface inflammation, promotes corneal repair, and increases tear secretion.In glaucoma treatment, kaempferol protects retinal ganglion cells and alleviates optic nerve damage.For retinal degenerative diseases, such as age-related macular degeneration, kaempferol protects retinal pigment epithelial cells from oxidative stress-induced damage and apoptosis.In ocular neovascular diseases, which encompass corneal, retinal, and choroidal neovascularization, kaempferol effectively blocks pathological neovascularization formation by inhibiting the expression and signaling of key proangiogenic factors, such as vascular endothelial growth factor.Kaempferol has significant therapeutic potential for multiple eye diseases through multi-target mechanisms, and its further research will provide a scientific basis for its clinical application and development of innovative therapeutics.This review summarizes recent advances in kaempferol research in ophthalmology.
