ObjectiveTo investigate the molecular mechanisms by which Acan-Gal-1 regulates macrophage immune phenotypes and Annexin A2/S100A10 membrane translocation in Angiostrongylus cantonensis. MethodsImmunofluorescence assay （IFA） was performed to determine the subcellular localization of Annexin A2 and S100A10 in macrophages. Flow cytometry and ELISA were used to assess functional changes in macrophage. siRNA interference of Annexin A2 was used to detect the effect of Acan-Gal-1 on various indicators. The expression levels of related genes and proteins were analyzed by Western blot， qRT-PCR， and ELISA methods. Bioinformatics analyses were conducted to characterize the structural features of Acan-Gal-1， and sequence alignment and molecular interaction prediction were performed to explore its potential interaction with Annexin A2. ResultsThis study found that Acan-Gal-1 can reverse LPS-induced promotion of macrophage migration and phagocytic function； it significantly upregulated M2-type markers in macrophages （Arg-1， IL-10， TGF-β） while inhibiting the expression of M1-type markers （iNOS， IL-6， IL-1β） induced by LPS. Acan-Gal-1 reduced the protein levels of Annexin A2 in macrophages under an immunologically activated state； after interfering with Annexin A2 expression， Acan-Gal-1 not only fails to induce macrophages to transition to an immunologically inhibitory phenotype but also fails to inhibit LPS-induced transition of macrophages to an immunologically activated phenotype. Although Acan-Gal-1 did not affect the expression of Annexin A2 or its chaperone protein S100A10 in macrophages， it markedly promoted their translocation to the plasma membrane. ConclusionsAcan-Gal-1 facilitates the enrichment of the Annexin A2/S100A10 complex at the macrophage membrane， thereby exerting immunomodulatory effects on macrophage polarization.

Background During urbanization, the passenger load on urban public transport systems continues to increase, exposing bus drivers to a high risk of musculoskeletal disorders (MSDs). This occupational health issue may also potentially compromise public transport safety. Objective To investigate the prevalence of MSDs among bus drivers in a first-tier city and to explore associated influencing factors. Methods A self-administered questionnaire survey was conducted from December 2024 to March 2025 among 1300 bus drivers in a bus company. Data were collected on general demographic information, occupational activities, and MSDs indicators. A total of 1268 valid questionnaires were returned, yielding a response rate of 97.5%. Descriptive statistics were used to analyze the distribution characteristics of MSDs. Pearson χ² tests were employed to examine the association between MSDs prevalence and individual/occupational characteristics. Logistic regression was performed to identify the influencing factors of MSDs. Results The survey revealed that the prevalence of MSDs among the bus drivers was 28.5%, with the highest prevalence in the 41–50 years age group (30.5%). The conditions primarily affected the cervical spine (60.5%) and lumbar spine (61.9%), with some cases involving multiple sites. The logistic regression model indicated that the following factors were associated with a higher risk of MSDs: frequent smoking (OR=1.477), poor or moderate self-reported health status (OR=4.422), 11–20 years of service (OR=1.749), daily cumulative driving time ≥361 min (OR=1.616), frequent whole-body fatigue during driving (OR=2.077), occasional whole-body fatigue during driving (OR=1.873), feeling tense during driving (OR=1.518), fatigue after work (OR=2.485), work-related stress (OR=1.882), and prolonged smartphone use with head-down posture (OR=1.671). Conversely, occasional exercise (OR=0.713)/frequent exercise (OR=0.569), driving intervals ≥21 min per round (OR=0.645), and perceiving the driving seat comfortable (OR=0.429) were associated with a lower risk of MSDs. Conclusion Physical exercise, smoking, years of service, daily cumulative driving time, driving intervals per round, prolonged smartphone use with head-down posture, self-reported health status, and psychological factors such as work-related stress are influencing factors for MSDs among bus drivers. Drivers should increase physical exercise and change unhealthy living habits. Employers should optimize working conditions, arrange reasonable driving schedules, and foster a positive work environment to reduce MSDs prevalence.

ObjectiveTo observe the effect of enriched environment (EE) combined with acupuncture at head point (HA) on behavior in rats with autism spectrum disorder. MethodsHealthy female Wistar rats were given peritoneal injection of sodium valproate at 12.5 days of gestation. Twenty-four male offspring rats were randomly selected and then randomly divided into model group (n = 6), EE group (n = 6), HA group (n = 6) and EE combined with HA group (the combined group, n = 6). Six male offspring rats born from female mice injected with the same amount of saline intraperitoneally were as control group. After four weeks of treatment, all the five groups were tested with three-chamber test and marble burying test, and the sociability index, the social novelty index and the number of buried marbles were recorded. The levels of interleukin (IL)-1β and IL-6 in peripheral blood were determined by enzyme-linked immunosorbent assay (ELISA). ResultsAfter treatment, compared with the model group, the sociability index and the social novelty index improved (P < 0.05), the number of buried marbles reduced (P < 0.05), and the levels of IL-6 and IL-1β in peripheral blood decreased in EE group, HA group and the combined group (P < 0.05); while the combined group was the best (P < 0.01). ConclusionBoth EE or acupuncture at HA could improve behavioral symptoms, and reduce the expression of inflammatory factors in rats with autism spectrum disorder. The combination of the two methods showed the best result.

{L-End}Objective To explore the suitable methods for individual occupational stress examination and evaluation for workers in China based on the electronics industry. {L-End}Methods A total of 1 164 workers from four electronics enterprises in Beijing City were selected as the research subjects using a convenient sampling method. The Occupational Stress Measurement Scale, which was developed based on the Japanese Brief Job Stress Questionnaire, was used to assess the occupational stress of the research subjects, and test the reliability and validity of the scale. Percentile norms and T-score norms were established, and the T-scores of the three dimensions of stress reaction (psychological reaction and physical symptoms), stress factors, and social support were divided into five stages using the normal distribution method with x¯±0.5 s and x¯±1.5 s, which was used to explore a proposed standard for assessing individual stress levels. {L-End}Results The revised scale consisted of 57 items, which could explain 64.0% of the total variation of occupational stress based on the result of item analysis and exploratory factor analysis. The results of confirmatory factor analysis showed that the model fitted well, with root mean square error of approximation of 0.052, standardized root mean square residual of 0.070, comparative fit index of 0.960, and Tucker-Lewis index of 0.958. The Cronbach's α coefficient of the scale was 0.951, and the Spearman-Brown coefficient was 0.837. Cronbach's α coefficients of the three dimensions ranged from 0.794 to 0.952, and the Spearman-Brown coefficients ranged from 0.737 to 0.850. The scores of the three dimensions of stress reaction, stress factors, and social support were (49.1±13.0), (44.9±7.7), and (18.1±3.6), respectively. Workers in the electronics industry met one of the following items were identified as the high level of occupational stress individuals: i) a score of stress reaction dimension ≥72.0 points; ii) a sum of stress factor and social support dimension scores ≥81.0 points, and a stress reaction dimension score ≥58.0 points. {L-End}Conclusion The Occupational Stress Measurement Scale and the criteria for determining high level of occupational stress can be used to assess the individual occupational stress levels of workers in the electronics industry in China. This method can provide a theoretical basis for the formulation of occupational stress examination and assessment for Chinese workers.

{L-End}Objective To analyze the current status of occupational stress and its influencing factors among workers in pharmaceutical enterprises in Beijing City. {L-End}Methods A total of 860 employees from six pharmaceutical enterprises in Beijing City were selected as the research subjects using convenience sampling method. The Chinese version of the New Brief Job Stress Questionnaire was used to evaluate the occupational stress, and multiple linear regression analysis was used to analyze the influencing factors of occupational stress. {L-End}Results The detection rate of high occupational stress was 1.40% (12/860). The results of multiple linear regression analysis showed that the workers with higher education level and longer length of service had a higher risk of high occupational stress (all P<0.01). Workers who were satisfied with their jobs had a lower risk of high occupational stress than those who were unsatisfied with their jobs (P<0.01). Workers who were satisfied with life had a significantly lower risk of high occupational stress than those who were unsatisfied with life (P<0.01). {L-End}Conclusion The detection rate of high occupational stress in workers of pharmaceutical enterprises is relatively low. Occupational stress is mainly affected by individual factors such as education level and length of service, and work and life satisfaction. Improving job and life satisfaction is helpful to reduce occupational stress level.

Objective:To explore the feasibility and clinical effect of the infrared vascular imager in the transplantation of free arterialized venous flaps.Methods:A retrospective analysis was conducted with patient data of hand microsurgery using free arterialized venous flaps to repair hand wounds in the Second Affiliated Hospital of Wenzhou Medical University from March 2019 to November 2020. An arterialized venous flap was designed according to the Goldschlager’s Type Ⅲ flap design with the aid of a magnifying glass following the venous course. The flap was transfer to cover the wound of the recipient area. The reconstructive effect was observed postoperatively, including the blood supply, color, texture, survival of the flap, the flexion and extension of the affected finger, and the appearance of the forearm donor site. The hand function was evaluated by the Chinese Medical Association Hand Surgery Society’s upper limb function evaluation trial standard.Results:A total of 17 patients were included, including 11 males and 6 females, ranging in age from 19 to 68 years old, with an average age of 34.6 years. A total of 18 skin flaps were designed and elevated, and the flap size ranged from 2.0 cm × 3.0 cm to 8.0 cm × 9.0 cm. The patients were followed up 3 to 12 months after the operation, with an average follow-up of 6 months. Blisters appeared on the second day after the operation in 8 flaps, and the affected limbs were raised to maintain the integrity of the blisters. The blisters of the flaps subsided one week after the operation. Congestion occurred on the second day after operation in 7 flaps, which subsided after two weeks after routine treatment, such as raising the affected limb and removing some sutures. One flap developed progressive hypoperfusion one week after the operation, and eventually necrosis. Seventeen flaps survived, and one flap failure was observe. All the surviving skin flaps were free of bloat and had a good appearance. In two cases, the skin graft area was pigmented, and the flexion and extension activities of the affected fingers were suitable. Using the Chinese Medical Association Society of Hand Surgery’s upper limb function evaluation trial standard, 16 patients (excluding one flap failure) were evaluated for hand function, showing 11 cases were excellent and 5 cases were good.Conclusions:Infrared vascular imaging technology enables free arterialized venous flap transplantation to realize non-contact, non-invasive, simple operation, intuitive and accurate, and truly realizes rapid flap design under direct vision. Infrared vascular imaging technology is an effective auxiliary tool for free arterialized venous flap transplantation.
