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.

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.

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 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.

Objective:To provide theoretical support and practice model for improving the clinical medical education supervision system of university-affiliated hospitals.Methods:This study focused on the group of reserve teaching supervision experts. Through literature research, questionnaire survey, and expert interview, the Competency Evaluation Criteria for Reserve Teaching Supervision Experts was constructed, which was implemented according to the training framework of "theory, practice, summary, and feedback". The paired t-test was performed using SPSS 24.0. Results:The research team formulated the Competency Evaluation Criteria for Reserve Teaching Supervision Experts through expert interviews. Six basic competencies and three advanced competencies for reserve teaching supervision experts were identified and their weights were assigned. A supervision team was established with supervision experts (including reserve teaching supervision experts) and teaching staff at a ratio of 1∶6.9, achieving an increase in the coverage of supervised specialties. A toolkit for enhancing the supervision capabilities of reserve experts was developed, and its effectiveness was analyzed. Statistical analysis showed that the overall score gap between reserve teaching supervision experts and senior supervision experts gradually narrowed. In terms of teaching demeanor and teaching effectiveness, there were no significant differences between the two types of experts. However, in terms of teaching content scores, there was a significant difference between reserve teaching supervision experts and senior supervision experts ( P<0.05). Conclusions:The training mechanism of reserve teaching supervision experts can effectively bridge the structural defects of the traditional supervision team. However, further emphasis is needed on the standardization and professionalization of teaching content supervision.

When bacteria inhabit an unfavorable environment, they adapt by forming small colony variants (SCVs) under selective pressure, resulting in a slow-growing subpopulation with distinct phenotypic and pathogenic characteristics. Phenotypically, SCVs exhibit a slow growth rate, atypical colony morphology, and unusual biochemical traits. Clinically, SCVs demonstrate reduced susceptibility to antibiotics and can persistently proliferate within the host environment as potential pathogens, posing a significant challenge for the treatment of associated infections. This paper analyzes the phenotypic, genetic, and clinical characteristics of SCVs to provide a reference for the clinical diagnosis and treatment of SCV infections.
