Objective To analyze the correlation between physical activity cognition and sleep quality in the working population, and to explore the mediating role of social support in the relationship between physical activity cognition and sleep quality. Methods A total of 1 824 working individuals in Hefei were assessed using the Pittsburgh Sleep Quality Index (PSQI), the Social Support Scale (SSRS), and a survey on physical activity cognition. Descriptive analysis and correlation analysis were conducted to examine the relationships among physical activity cognition, social support, and sleep quality in the working population. The Process macro was utilized to explore the mediating effect of social support between physical activity cognition and sleep quality. Results Statistical analysis indicated a negative correlation between overall PSQI scores and physical activity cognition (r=-0.106, P<0.001), a negative correlation between PSQI scores and social support (r=-0.243, P<0.001), and a positive correlation between social support and physical activity cognition (r=0.235, P<0.001). Social support was found to have a partial mediating effect between physical activity cognition and sleep quality, accounting for 40.71% of the mediating effect. Conclusion There is a relationship among social support, physical activity cognition, and sleep quality. Physical activity cognition can directly influence sleep quality in the working population or affect it through the mediating role of social support. Enhancing the enthusiasm for physical activity participation and increasing levels of social support can contribute to improving sleep quality. [ABSTRACT FROM AUTHOR]

残余应力是影响钢压杆整体稳定承载力的重要缺陷因素之一。为获得合理的国产Q460高强钢焊接T形截面残余应力分布模型,采用锯割法对不同截面尺寸的8个试件进行残余应力试验研究。根据实测数据,绘制各截面的残余应力分布图,研究板件宽厚比、板件厚度对残余应力大小及分布宽度的影响,组成截面各板件间的相关性及残余应力的自平衡性。分析结果表明:焊缝处残余拉应力大小与板件厚度及板件宽厚比无关,相应的分布宽度与板件厚度及板件宽厚比成反比;板件外伸段中部的残余压应力大小与板件厚度和板件宽厚比成反比,相应的分布宽度与板件厚度和板件宽厚比无关;各板件内的残余应力能够分别满足自平衡条件,且全截面上的残余应力也能满足自平衡条件。基于上述分析结果,提出能够准确描述试验结果的国产Q460高强钢焊接T形截面残余应力分布模型,并进行有限元分析验证,为后续焊接T形截面钢压杆整体稳定承载力的研究提供重要参考。

【Objective】Ubiquitin-binding enzyme E2（UBC）is an important transit enzyme in the ubiquitin-proteasomal pathway that transfers ubiquitin to target proteins, which is involved in plant growth and development and many stresses. The E2 gene family members were identified from the whole genome of pepper, and the expression patterns of related genes were analyzed, which provided a theoretical basis for subsequent research.【Method】Based on the genome-wide information of pepper, the E2 family was identified by bioinformatics. The basic physio-chemical properties, subcellular localization, chromosomal localization, gene structure and phylogenetic analysis, cis-acting elements, abiotic stress response, tissue and organ expression patterns, and protein-protein interaction network of the family members were systematically analyzed.【Result】There were 48 members in the E2 gene family, which were unevenly distributed on 11 chromosomes, and its encoded proteins were mainly localized in the extracellular and nucleus. After comparative evolutionary analysis of pepper, tomato and Arabidopsis thaliana, they were divided into the Group I-Group XIII subfamily, which had similar conserved protein motifs and gene structures. A total of 26 proteins were found to interact. The cis-element analysis showed that the promoter region of CaUBC gene contained a large number of lightresponsive and hormone-responsive elements, and there were a variety of cis-acting elements related to growth, development and stress resistance in the upstream 2 000 bp region. CaUBC was involved in the stress, under different abiotic stresses and hormone treatments, they were divided into three categories, among which the third type of genes were highly expressed in high temperature environment; different expressions showed in tissues and organs, among which the expression of CaUBC38 in fruits changed significantly. RT-qPCR analysis showed that the relative expression was the highest at 50 d and the lowest at 10 d.【Conclusion】The 48 members of E2（CaUBC）gene family are systematically identified from the pepper genome. The expression characteristics of CaUBC family members during its growth, development, and abiotic stress responses are revealed. [ABSTRACT FROM AUTHOR]

In order to adhere to the consolidation of household contracted management, innovate and improve the dual management system combining centralization and decentralization (DMS), and give full play to the function and role of rural collective organizations in the centralization of small farmers, the status of economic development of 47 rural collective organizations and 4 practical models that can be copied and promoted in Guangxi were studied by adopting methods such as literature combing, field survey, case demonstration and clustering and comparison and statistical analysis. The research found that in recent years, although the village collectives in Guangxi have completed the equity reform of collective assets, and the collective incomes have increased, the overall operation vitality is still relatively weak, the organization and service degree for small farmers is relatively low, and the adhesion between village and household in production and operation is small. The 4 practical models analyzed show that, compared with capital-oriented business entities such as enterprises, village collective economic organizations have stronger adaptability to the management of small farmers, being important new business entities to organize and serve small farmers. Therefore, it is suggest that it should be made good use of the results of the “three transformations” reform of rural collective assets, to carry out the pilot of the innovative development of the DMS, to speed up the supply of laws and regulations of village collective economic organizations, to establish a mechanism of financial investment to cover village collectives and to extend to small farmers preferentially, and to develop the village collective economy with the support of village-equity economic cooperatives so as to organize and drive small farmers to integrate into the development of modern agricultural industrialization.

Objective To explore the changes of migration ability and CXCR3 expression level of human urethral stricture scar fibroblasts in different dihydrotestosterone (DHT) environments and the possible underlying related biological signaling pathways. Methods Different concentrations of DHT were selected to act on human urethral stricture scar fibroblasts, and the effect of different concentrations of DHT on the migration ability of fibroblasts was studied by Transwell test. The expression of GXCR3 receptor of different fibroblasts was detected by Western blotting. The diflerent concentrations of DHT group and the alcohol-stimulated blank control group were used for macroscopic analysis of transcriptome sequencing technology (RNA-seq) to find the potential related biological signaling pathways between DHT and CXCR3. Results Transwell experiments confirmed that with the gradual increase of DHT concentration, the migration ahility of fibroblasts was correspondingly weakened. At the same time, the DHT solution environment with a stepwise increase in concentration can significantly increase the expression of CXCR3 in fibroblasts, and the expression of CXCR3 receptor was significantly decreased after adding enzalutamide to antagonize androgen receptor (AR). Androgen treatment can significantly change the expression of some genes, mainly enriched in TGF-β signaling pathway, cell adhesion signaling pathway, rheumatoid inflammation signaling pathway, MAPK signaling pathway, Ras signaling pathway, cytoskeleton signaling pathway, Hippo signaling pathway, WNT signaling pathway, etc. Conclusion In the high concentrations of androgen environment, the migration of human urethral stricture scar fibroblasts has obvious changes, which is negatively related to the expression of CXCR3. The underlying reason may be related to TGF-p signal pathway, cell adhesion signal pathway and other signal pathways. [ABSTRACT FROM AUTHOR]
