Suspended microorganisms often experience diminished efficacy in the bioremediation of polycyclic aromatic hydrocarbons (PAHs). In this study, the potential of zeolite imidazolate framework-8 (ZIF-8) and the eco-friendly modifier citric acid (CA) was harnessed to generate a biomimetic mineralized protective shell on the surface of Bacillus subtilis ZL09-26, resulting in an enhanced capability for PAH degradation. This investigation encom-passed the integrated responses of B. subtilis ZL09-26 to ZIF-8 and ZIF-8-CA at both cellular and proteomic levels. The amalgamation of ZIF-8 and CA not only stimulated the growth and bolstered the cell viability of B. subtilis ZL09-26, but also counteracted the toxic effects of phenanthrene (PHE) stress. Remarkably, the bioremediation prowess of B. subtilis ZL09-26@ZIF-8-CA surpassed that of ZL09-26@ZIF-8 and ZL09-26, achieving a PHE removal rate of 94.14 % within 6 days. After undergoing five cycles, ZL09-26@ZIF-8-CA demonstrated an enduring PHE removal rate exceeding 83.31 %. A complex interplay of various metabolic pathways orchestrated cellular responses, enhancing PHE transport and degradation. These pathways encompassed direct PHE biodegradation, central carbon metabolism, oxidative phosphorylation, purine metabolism, and aminoacyl-tRNA biosynthesis. This study not only extends the potential applications of biomineralized organisms but also offers alternative strategies for effective contaminant management.

Water pollution is a long-standing problem in the natural environment. Various emerging organic and inorganic pollutants are major environmental contaminants in water bodies, such as pharmaceuticals, personal care products (PPCPs), industrial compounds, poly/perfluorinated compounds, and pesticides. The elimination of environmental contaminants in nature has been extensively investigated using a variety of classic physical, chemical and biological approaches, providing a solid base for advanced technology. Metal-organic frameworks (MOFs), a newly discovered family of multifunctional porous materials with high porosity and excellent controllability, have demonstrated an undeniable power in water purification. In this review, we provide a valuable resource for researchers who intend to use the application of MOFs to remediate emerging contaminants (ECs) in bodies of water. Firstly, we briefly outline the traditional physical, chemical, and biological methods applied to remove a wide range of pollutants from water. Moreover, we summarize the application of MOFs as excellent adsorbents, catalysts, and enzyme immobilization carriers for treating pollutants in wastewater. And the challenges and perspectives in the current field were also discussed.

Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic and ubiquitous pollutants that need to be solved. The low-molecular-weight organic acid (LMWOA) holds the promise to accelerate the capacity of microbes to degrade PAHs. However, the degradation mechanism(s) with multi-LMWOAs has not been understood yet, which is closer to the complex environmental biodegradation in nature. Here, we demonstrated a comprehensive cellular and proteomic response pattern by investigating the relationship between a model PAH degrading strain, B. subtilis ZL09-26, and the mixture LMWOAs (citric acid, glutaric acid, and oxalic acid). As a result, multi-LMWOAs introduced a highly enhanced phenanthrene (PHE) degradation efficiency with up to 3.1-fold improvement at 72 h, which is accompanied by the enhancement of strain growth and activity, but the releasement of membrane damages and oxidative stresses. Moreover, a detailed proteomic analysis revealed that the synergistic perturbation of various metabolic pathways jointly governed the change of cellular behaviors and improved PHE degradation in a network manner. The obtained knowledge provides a foundation for designing the artificial LMWOAs mixtures and guides the rational remediation of contaminated soils using bio-stimulation techniques.

At last, it is explained from the WHO level, international level, national and personal level, and involving trade tourism, international exchanges, gov-ernment organization measures, personal health, etc., aiming to supplement the existing WHO’s guidelines for the response of health organizations to major infectious diseases.

从布迪厄的“社会阶层”理论出发,基于CGSS二期数据探讨了中国城镇化进程中城乡居民现场观赏型体育消费分层现象及影响机制.通过多层次logistic回归分析,得出如下结论:(1)现场观赏型体育消费尚未成为一种大众消费方式,中国公众到现场观看体育比赛存在社会阶层区隔;(2)现场观赏型体育消费分层是个体所在的社会阶层及所嵌入的社会结构、资源环境等要素共同作用的结果;(3)在城镇化进程中,农村和城镇存在不同的现场观赏型体育消费分层机制.研究揭示,社会阶层是体育消费领域一个需要深入探讨的变量,体育消费在社会阶层再生产中具有重要的意义,但这种“文化转向”的阶层分析不能囿于行动者的社会阶层,还应关注行动者所嵌入的更广阔的社会结构和资源环境.

Objective: To assess the effectiveness of interventions on patient trust Methods: A system review was conducted through searching 11 relevant databases, such as Cochrane Library, EMBASE, PsycINFO, CINAHL, PubMed, Web of Science, SinoMed, CNKI, WANFANG. The randomized controlled trials (RCTs) were screened from 1539 original studies according to inclusion and exclusion criteria Meta-analysis was used to evaluate and interpret the interventions. Results: Ten RCTs were included in the review. It was concluded from meta-analysis that no significant difference could be found between controlled and intervention groups by increasing doctors'abilities(SMD = -0.05, 95％ CI: -0.22 -0.12); while the other two interventions, doctor's information disclosure as well as patient education and nursing intervention, significantly enhanced patient trust (SMD = 0.13, 95％ CI: 0.06 - 0.21; SMD = 0.60, 95％ CI: 0.29 - 0.90). Conclusion: Doctor's information disclosure, patient education and nursing intervention are effective in increasing patients'trust, while intervention of doctor's ability promotion seems not so remarkable.

运用中国综合社会调查(CGSS2012)数据,基于代际视角探讨流动人口体育参与对其幸福感的影响.研究发现:(1)流动人口的体育参与能显著提升其幸福感,“健康”和“社会资本”是影响流动人口体育参与和主观幸福感关系的重要机制;(2)流动人口的主观幸福感存在显著的代际差异,而体育参与及其因素对其幸福感的影响在新老两代流动人口间也存在显著差异.基于此,在政策层面,针对流动人口体育参与的不同代际需求,构建多元、差异化的流动人口公共体育服务政策体系,为流动人口提供公平、与其切身利益密切相关的公共体育服务,从而提升流动人口体育参与水平,更好地发挥体育参与促进流动人口积极幸福体验的作用.
