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.

BACKGROUND:Repetitive trans-spinal magnetic stimulation(rTSMS)can inhibit inflammatory responses following spinal cord injury.rTSMS applies magnetic field stimulation to the spinal cord region to modulate neuronal excitability and synaptic transmission,thereby promoting plasticity and repair of the nervous system. OBJECTIVE:To observe the effects of rTSMS on the Toll-like receptor 4(TLR4)/nuclear factor(NF)-κB/NLRP3 signaling pathway after spinal cord injury and explore its mechanism in promoting motor function recovery. METHODS:Male C57BL/6J mice,SPF grade,were randomly divided into sham surgery group,spinal cord injury group,and rTSMS group.The latter two groups of mice were anesthetized and the T9 vertebral plate was removed using rongeur forceps to expose the spinal cord,and the spinal cord was clamped using a small aneurysm clip for 20 seconds to establish the spinal cord injury model.Mice in the rTSMS group underwent a 21-day rTSMS intervention starting on day 1 after spinal cord injury.The stimulation lasted 10 minutes per day,5 days per week with an interval of 2 days.Basso Mouse Scale scores were used to assess motor function recovery in mice after spinal cord injury at 1,3,7,14,and 21 days after spinal cord injury.Western blot was employed to detect the expression of AQP4,apoptotic factors Bax,Bcl-2,CL-Caspase-3,inflammatory factors tumor necrosis factor-α,interferon-γ,interleukin-6,interleukin-4,and the TLR4/NF-κB/NLRP3 signaling pathway related proteins in the injured spinal cord.Oxidative stress assay kit was used to measure the activity of superoxide dismutase,glutathione peroxidase,and malondialdehyde content at the site of spinal cord injury.Immunofluorescence staining was performed to detect the expression of neuronal nuclei(NeuN). RESULTS AND CONCLUSION:The Basso Mouse Scale score in the rTSMS group was significantly higher than that in the spinal cord injury group(P<0.05).Compared with the spinal cord injury group,the rTSMS group showed a reduction in spinal cord water content.The expression of AQP4 protein,malondialdehyde content,and expression of Bax,Bcl-2,CL-Caspase-3,tumor necrosis factor-α,interferon-γ,interleukin-6,and TLR4/NF-κB/NLRP3 signaling pathway related proteins were all decreased in the rTSMS group,while the activities of superoxide dismutase and glutathione peroxidase,as well as the expression of Bcl-2,interleukin-4,and NeuN,were all increased(P<0.05).These results suggest that rTSMS downregulates the expression of proteins related to the TLR4/NF-κB/NLRP3 signaling pathway,alleviating symptoms after spinal cord injury such as spinal cord edema,oxidative stress,apoptosis,and inflammation,exerting neuroprotective effects,and thereby promoting the recovery of hindlimb motor function after spinal cord injury.

With the development of science and technology, electronic devices have become an inevitable part of our daily life and work. There has been an increase of interest in the use of various video display terminals(VDT). The ocular surface is the first barrier of the visual system to resist the damage of the external environment. In recent years, the number of patients with dry eye has consistently increased with the excessive use of VDT. Blue light produced by VDT, with wavelengths ranging from 400 to 500 nm, has a high energy in visible light. Therefore, blue light may also be an important risk factor for dry eye. In particular, the outbreak of COVID-19 has left people worldwide suffering from increased blue light, which promotes further research into dry eye caused by blue light emitted from VDT. In this review, we summarize the recent studies on the role of blue light produced by VDT in dry eye to provide reference for future related research.

The proliferation of antibiotic-resistant Staphylococcus aureus poses an escalating threat to global public health.These superbugs have developed resistance to multiple antimicrobial agents, significantly increasing treatment complexity and costs. In the face of this challenge, the development of novel antimicrobial drugs is imperative, yet traditional research and development pathways are hindered by high costs and a lack of new targets. In recent years, researchers have pioneered an innovative approach: re-evaluating the antimicrobial potential of existing non-antibiotic drugs. This drug repurposing strategy leverages the known pharmacological properties of existing drugs, offering new perspectives for antimicrobial therapy. This paper reviews the mechanisms of action of 15 non-antibiotic drugs, including Diacerein and Niclosamide, in combating drug-resistant Staphylococcus aureus strains. This research not only provides new options for clinical practice but also paves innovative pathways for addressing bacterial resistance. Through interdisciplinary collaboration and innovative thinking, the battle against these multidrug-resistant pathogens is poised to achieve breakthrough progress.

Purpose: Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms. Materials and Methods: Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A. Results: TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer. Conclusion TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.

RESULTS In myocardial ischemia tests， Tianjiang xueshuantong pills significantly reduced the percentage of myocardial infarction and the levels of CK-MB， LDH， MDA， GSH， IL-6， TNF-α， IL- 1β， and MCP-1 in serum （P＜0.05 or P＜0.01）. In hyperlipidemia tests， high dose of Tianjiang xueshuantong pills significantly reduced the serum levels of TC， LDL and significantly increased the level of HDL in rats after 2 weeks and 4 weeks of administration. In blood stasis tests， different doses of Tianjiang xueshuantong pills significantly reduced MAR of rats （P＜0.01）. In artery thrombosis tests， high dose of Tianjiang xueshuantong pills significantly prolonged the time of thrombosis formation （P＜ 0.01）， significantly reduced the weight and protein content of thrombus and the level of PAI-1 in serum （P＜0.01）. CONCLUSIONS Tianjiang xueshuantong pills exert therapeutic effects on coronary heart disease through multi-dimensional synergistic actions， including anti-myocardial ischemia， lipid-lowering， and anti-thrombotic effects.

Objective:To understand the prevalence of hearing loss among individuals aged 60 and above undergoing physical examinations and to explore the feasibility of using pure tone audiometry (PTA) for hearing screening in the elderly population, as well as to establish screening criteria suitable for our country.Methods:The study was a cross-sectional study, a total of 1 066 elderly individuals (619 males and 447 females; Age range: 60-90 years old, with an average of 66.5 years old) who underwent physical examinations at the Peking Union Medical College Hospital physical examination center from February to December 2023, were screened using PTA and the Chinese version Hearing Handicap Inventory for the Elderly Screening (CHHIE-S). Different screening criteria were applied to calculate the proportion of individuals who did not pass the PTA screening in the elderly population. The consistency between these results and the screening outcomes of the CHHIE-S scale was analyzed to explore reasonable screening standards. We performed statistical analysis using SPSS 27.0.Results:It was found that 18.39% of the elderly population had moderate or severe hearing loss. The positive rate determined by the detection of pure tones at a fixed dB level was significantly higher than that based on the average hearing threshold across 0.5, 1, 2, and 4 kHz frequencies (4-frequency pure-tone average, 4fPTA), and the difference was statistically significant ( χ2=136.56, P<0.001). The criterion of 4fPTA>35 dB HL in the better ear showed the highest consistency with the criterion of CHHIE-S>8, with a Kappa value of 0.554 ( P<0.001), and this criterion resulted in a positive rate of 15.57% (166/1 066). Conclusions:Conducting hearing screening based on PTA among the elderly population undergoing physical examinations is an effective and feasible approach. Given the subjective perceptions of the elderly population being screened, a 4fPTA greater than 35 dB HL in both ears might be a reasonable criterion.

Objective To investigate the differences in speech recognition in noise between patients with con-genital and acquired single-sided deafness.Methods Sixty-two patients with single-sided deafness were included in this study,which included 31 congenital single-sided deafness(CSSD)cases and 31 acquired single-sided deafness(ASSD)cases according to the onset of deafness.Thirty-one normal hearing(NH)subjects were also included in this study as the control group.The ability of speech recognition in noise were tested and compared among the three groups,meanwhile the differences between patients with left and right single-sided deafness were compared.Results The speech recognition threshold in noise of ASSD patients was significantly higher than that of CSSD patients,and both of them were significantly higher than that of the NH subjects.Under the 0 and-2 dB signal-to-noise ra-tio conditions,the speech recognition score was significantly lower in ASSD patients compared to CSSD patients,but only in ASSD patients it was significantly lower than that of the NH group,with no significant difference be-tween CSSD patients and the NH group.A significant difference in speech recognition thresholds was observed be-tween left and right CSSD patients.Conclusion CSSD have better speech recognition in noise than ASSD patients,suggesting better central function compensation.In addition,the side of deafness affects the speech recognition per-formance of CSSD patients.
