Objective:To observe the current status of the use of personal protective equipment (PPE) by the dust working population, and to analyze the factors affecting its use, so as to provide a reference basis for proposing scientific intervention methods.Methods:From October to December 2023, random sampling method was used to conduct a self-designed Questionnaire on the Use of Personal Protective Equipment by the Dust Working Population. A total of 1216 dust workers were randomly selected from each city in Guangdong Province, and their mask wearing status was evaluated. The Wilcoxon rank sum test was used for comparison between measurement data sets, and the Chi-square test or Fisher exact probability method was used for counting data. A binary logistic regression model was used to analyze the factors affecting the use of PPE in dust workers.Results:The correct rate of wearing PPE in dust working group was 66.12% (804/1216). In univariate analysis, there were statistical significances in different knowledge score, wearing PPE to reduce exposure to dust particles, wearing occupational health protective equipment such as masks was uncomfortable, wearing occupational health protective equipment such as masks reduced work efficiency, attending pre-employment occupational health examination, attending occupational health examination on a regular basis, receiving occupational health training during work in the enterprise, being urged or reminded by workmates, supervisors, or family members to use PPE, the correct use of PPE when workers or shift leaders were exposed to dust particles, second-hand smoke inhalation, smoking, and alcohol consumption ( P<0.05). Multiple logistic regression results showed that gender ( OR=2.00, 95% CI: 1.48-2.72), knowledge score ( OR=1.18, 95% CI: 1.11-1.26), neutral attitude towards the discomfort of wearing occupational health protective equipment such as masks during work ( OR=1.64, 95% CI: 1.18-2.27), and participation in pre-job occupational health examination ( OR=0.23, 95% CI: 0.10-0.54) were the main influencing factors on the use of PPE to be worn correctly ( P<0.05) . Conclusion:The rate of correct wearing of PPE for dust working population still needs to be improved. Factors such as gender, knowledge score, neutral attitude towards the discomfort of wearing masks during work, and participation in pre-job occupational health examination may be the influencing factors on the use of PPE for dust working population.

Objective:To analyze the correct use of personal protective equipment (PPE) among noise-exposed workers and its influencing factors, providing reference information for noise intervention efforts.Methods:In September 2023, a stratified sampling method was employed. Based on the 2022 gross domestic product (GDP) rankings of cities in Guangdong Province, 21 prefecture-level cities were divided into economically developed and less developed groups. Two cities were randomly selected from each group, and 16 to 17 enterprises were randomly chosen from each city as study sites. Twenty workers were included from each enterprise as study subjects. A total of 1200 questionnaires were distributed and collected, and 1099 were valid, with an effective recovery rate of 91.6%. The correctness of hearing protector usage was evaluated according to the GB/T 23466-2009 "Guidelines for the Selection of Hearing Protectors", and the personal attenuation rating values of the workers' hearing protectors were measured. A self-designed Questionnaire on the Use of Hearing Protectors by Noise-Exposed Workers was used to investigate PPE-related usage. Multivariate logistic regression analysis was conducted to identify factors influencing the correct use of PPE.Results:A total of 429 (39.0%) noise-exposed workers were able to use PPE correctly during work. Multivariate logistic regression analysis showed that age, working hours, gender, occupational noise protection knowledge score, whether PPE was checked after use, and the frequency of peer supervision on PPE usage were significant factors influencing the effective use of PPE ( P<0.05) . Conclusion:The correct use of PPE by noise-exposed workers still needs to be improved. The level of occupational health education in enterprises should be enhanced to promote the correct use of PPE by noise-exposed workers.

Secondary metabolites of medicinal plants are extremely important to human health because of their special pharmacological activities or efficacy. They are the main source of drugs, health care products, and cosmetics. As human beings continue to pursue health and longevity, the demand in the pharmaceutical market continues to grow. It becomes especially important to improve the production and quality of secondary metabolites of medicinal plants. Plant secondary metabolites are a kind of adaptation of plants to their environment and are the result of the interaction between plants and biotic and abiotic factors during the long-term evolution process. The production and accumulation of secondary metabolites in medicinal plants are mainly affected by plant genetic factors and environmental factors. Among them, light environment is extremely important for their synthesis. Therefore, light regulation has long been a research focus for many scholars in China and abroad. In this article, we the recent research progress on the effects of light regulation on the secondary metabolites of medicinal plants were reviewed, mainly focusing on the effects of light quality, light intensity and photoperiod, in order to provide theoretical basis and practical guidance for the efficient production of secondary metabolites with important pharmacological activities.

Objective:To investigate the prospective association of sleep duration with the development of chronic obstructive pulmonary disease (COPD) in adults in Suzhou.Methods:The study used the data of 53 269 participants aged 30-79 years recruited in the baseline survey from 2004 to 2008 and the follow-up until December 31, 2017 of China Kadoorie Biobank (CKB) conducted in Wuzhong District, Suzhou. After excluding participants with airflow limitation, self-reported chronic bronchitis/emphysema/coronary heart disease history at the baseline survey and abnormal or incomplete data, a total of 45 336 participants were included in the final analysis. The association between daily sleep duration and the risk for developing COPD was analyzed by using a Cox proportional hazard regression model, and the hazard ratio ( HR) values and their 95% CI were calculated. The analysis was stratified by age, gender and lifestyle factors, and cross-analysis was conducted according to smoking status and daily sleep duration. Results:The median follow-up time was 11.12 years, with a total of 515 COPD diagnoses in the follow-up. After adjusting for potential confounders, multifactorial Cox proportional hazard regression analysis showed that daily sleep duration ≥10 hours was associated with higher risk for developing COPD ( HR=1.42, 95% CI: 1.03-1.97). The cross analysis showed that excessive daily sleep duration increased the risk for COPD in smokers ( HR=2.49, 95% CI: 1.35-4.59, interaction P<0.001). Conclusion:Longer daily sleep duration (≥10 hours) might increase the risk for COPD in adults in Suzhou, especially in smokers.
