Objective To investigate the prevalence and influencing factors of work-related musculoskeletal disorders (WMSDs) in neck, shoulders and lower back among power grid workers. Methods A total of 371 workers from a power grid enterprise in Guangdong Province were selected as the research subjects using the convenience sampling method. A cross-sectional survey of WMSDs in the neck, shoulders and waist of the workers was conducted using the modified Musculoskeletal Disorders Questionnaire. Results The overall prevalence of WMSDs among the power grid workers was 62.8%, with prevalence of 37.2%, 33.7% and 32.1% for WMSDs in neck, shoulders and lower back, respectively. Binary logistic regression analysis showed that power grid workers who did not maintain a good sitting posture or were unable to maintain good sitting posture over prolonged periods had a higher risk of neck WMSDs than those who maintained a good sitting posture (both P<0.01). A higher frequency of head-down posture during work was associated with an increased risk of neck WMSDs (both P<0.05). Female workers had a higher risk of shoulder WMSDs than male workers (P<0.05). A higher frequency of early awakening with inability to fall back asleep, as well as a higher frequency of head-down posture during work, were both associated with an increased risk of shoulder WMSDs (all P<0.05). Workers with a sedentary habit had a higher risk of shoulder WMSDs than those without (P<0.01). Workers with insufficient rest time had a higher risk of shoulder WMSDs than those with sufficient rest time (P<0.01). Both maintenance workers and managers had a higher risk of lower back WMSDs than workers in other occupational categories (all P<0.05). Workers who experienced nocturnal awakening with difficulty falling back asleep at frequency of several times per year, ≥1 time /month, ≥1 time /week, had higher risk of lower back WMSDs than those who never experienced such problem (all P<0.05). Workers with a sedentary habit and those uncertain about having a sedentary habit both had a higher risk of lower back WMSDs than those without (both P<0.05). Greater forward neck flexion during work was associated with an increased risk of lower back WMSDs (both P<0.05). Workers who occasionally tilted their necks to the side while working had a higher risk of lower back WMSDs than those who did not (P<0.05). Conclusion WMSDs are highly prevalent among power grid workers, particularly affecting the neck, shoulder, and waist. Influencing factors include individual characteristics, behavioral habits, work organization, work posture, and workload. Maintaining proper posture and adequate rest may reduce the risk of WMSDs.

Objective To investigate the effect and mechanism of miglitol on regulating the energy metabolism of brown adipocytes by activating UCP1 and preventing cold injury in mice after cold exposure. Methods Primary brown adipocytes were induced into mature adipocytes, the effect of miglitol on the viability of brown adipocytes was investigated by MTT method, the lipid droplet consumption level of cells after drug administration was investigated by Oil Red O staining technology, and the level of UCP1, a key protein of thermogenesis in brown adipocytes, was detected by Western blotting. The activity of anti-frostbite was investigated in cold exposure at 4 ℃ and −20 ℃. KM mice, which were randomly divided into control group, cold exposure group, miglitol group and all-trans retinoic acid group, and after 7 days of repeated administration, the body surface temperature of mice was detected by infrared thermal imaging system, the anal temperature change was detected by anal thermometer, and the expression levels of UCP1 and PGC1-α in adipose tissue were detected by immunoblotting. Results Compared with the control group, the lipid droplet consumption and UCP1 expression levels in brown adipocytes in the miglitol group were significantly increased. The levels of body surface temperature and rectal temperature increased significantly after cold exposure, and the levels of UCP1 and PGC1α in the brown adipose tissue of mice increased significantly, which indicated that the miglitol could activate the critical proteins UCP1 and PGC1α of the thermogenesis pathway, increase the thermogenesis of mice after cold exposure, and thus improve the effect of cold injury for toe swelling. Conclusion Miglitol could play a role in improving cold injury and body temperature in mice by increasing the level of UCP1 and PGC1α, which are key targets of the thermogenesis pathway to promote the thermogenesis of brown fat.

BACKGROUND/OBJECTIVES: Stroke represents the primary cause of death and persistent disability globally, leading to around 5.5 million annual patient fatalities. The objective was to explore the relationship of dietary fiber with all-cause and cardiovascular disease (CVD) mortality risk in patients with stroke. SUBJECTS/METHODS: We extracted stroke patients’ data from the National Health and Nutrition Examination Survey (NHANES) database. All-cause and CVD mortality were outcomes. Dietary fiber consists of non-digestible forms of carbohydrates, usually polysaccharides that originate from plant-based foods. Covariates including demographic data, vital signs, comorbidities, laboratory parameters, and medication use were screened using the weighted multivariate Cox regression models with backward elimination. Weighted univariate and multivariate Cox regression models were performed to explore the relationship between dietary fiber intake and all-cause/CVD mortality, with hazard ratios (HRs) and 95% confidence intervals (CIs). The association was further investigated in different subgroups. RESULTS: A total of 1,578 patients with stroke were included, of whom 688 (43.6%) died.Total fiber and vegetable fiber intake were analyzed as categorical variables, and the lowest intake was considered reference groups. High intake of total fiber (HR, 0.73; 95% CI, 0.57–0.94) and high intake of vegetable fiber (HR, 0.63; 95% CI, 0.48–0.82) were related to lower all-cause mortality risk in individuals with stroke. Similar findings were also observed between higher total fiber (HR, 0.56; 95% CI, 0.37–0.85) and vegetable fiber intake (HR, 0.57; 95% CI, 0.36–0.89) with decreased CVD mortality risk. The relationship between higher total fiber intake and lower all-cause mortality risk was discovered in individuals aged ≥ 60 yrs, smoking, non-CVD, and chronic kidney disease (CKD). High total fiber, or vegetable fiber consumption was linked to lower CVD mortality risk in stroke individuals aged ≥ 60 yrs, females, body mass index ≥ 30 kg/m 2 , non-smoking, and CKD. CONCLUSION Dietary fiber intake and vegetable fiber intake may benefit the prognosis of patients with stroke. Increasing dietary fiber consumption, especially vegetable fiber intake, potentially benefits the prognosis of stroke patients.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

Crohn's disease（CD）is a chronic non-specific inflammatory bowel disease with unclear etiology and pathogenesis. Endoscopy combined with pathological examination remains the gold standard for diagnosing and monitoring CD activity. However，endoscopy is limited to the mucosal surface and intestinal lumen，making it difficult to assess the full thickness of the intestinal wall and extraintestinal conditions，and it cannot reach the proximal end of a narrowed intestinal segment. Additionally，endoscopic biopsy is invasive，requires thorough bowel preparation，and is poorly tolerated by infants and young children.This article reviews recent research advances in non-invasive examination methods for CD patients，including non-invasive biomarkers in blood and stool，as well as non-invasive imaging techniques，and their potential applications in the diagnosis and treatment of CD. By integrating these biomarkers with clinical parameters，it is possible to reduce reliance on invasive testing，optimize personalized treatment strategies，and enable early identification of disease activity and remission status. This comprehensive approach allows for more accurate assessment of disease progression，adjustment of treatment plans，and the delivery of more precise and individualized care for CD patients，ultimately improving their prognosis and quality of life.

Objective To investigate the situation and influencing factors of preserved ratio impaired spirometry (PRISm) among dust-exposed workers in a wooden furniture manufacturing enterprise. Methods A total of 562 dust-exposed workers from a wooden furniture enterprise in Guangdong Province were selected as the study subjects using the convenience sampling method. The result of health-status questionnaire and occupational medical examinations among the participants were studied, and the influencing factors of PRISm were studied using the binary logistic regression analysis method. Results The detection rate of PRISm was 22.1% (124/562) among the study subjects. Binary logistic regression result showed that male workers had a higher risk of PRISm than female workers (P<0.01). Current smokers had a higher risk of PRISm than non-smokers (P<0.05). Workers with longer duration of exposure to occupational hazards had a higher risk of PRISm (P<0.05), those with higher grade of small-airway dysfunction had a higher risk of PRISm (P<0.01). In terms of body mass index, overweight or obese workers showed a higher detection rate of PRISm than those with normal weight (P<0.01). Greater amount of smoking pack per year had a higher risk of PRISm (P<0.01). Conclusion Dust-exposed workers in the wooden furniture manufacturing industry show a relatively high detection rate of PRISm. Male, current smoker, longer duration of exposure to occupational hazards, small airway dysfunction, overweight or obese, and smoking pack per year are influencing factors of PRISm among the dust-exposed workers in the wooden furniture manufacturing industry.
