 摘要： [Objectives] To investigate the impact of the returning entrepreneurial vitality of migrant workers in the major grain-producing areas of the six central provinces on the common prosperity of counties, examine the mediating role of factor integration in this relationship, and identify the heterogeneous effects across different types of counties. [Methods] This study focused on 178 national-level major grain-producing counties across six central Chinese provinces: Shanxi, Henan, Hubei, Anhui, Hunan, and Jiangxi. Utilizing balanced panel data from 2011 to 2022 (a total of 2 136 observations), it developed an evaluation system (prosperity, commonality, and sharing) and a factor integration index (capital, labor, land, technology) to assess the level of common prosperity in these counties. Empirical analyses were performed using fixed-effect and mediating effect models. [Results] The returning entrepreneurial vitality of migrant workers has a significantly positive impact on the comprehensive index of common prosperity in counties (coefficient 0.065, p<0.01). It also positively influences the three sub-dimensions of prosperity, sharing, and commonality. Factor integration serves as a partial intermediary, with migrant workers’ entrepreneurial vitality indirectly promoting common prosperity by enhancing the efficiency of the aggregation and allocation of production factors. This enabling effect is particularly pronounced in core grain-producing areas and counties with lower levels of economic development. [Conclusions] The returning entrepreneurial vitality of migrant workers can significantly boost the level of common prosperity in major grain-producing counties, with factor integration serving as the key transmission pathway. It is recommended to dismantle institutional barriers between urban and rural factor markets, particularly focusing on major grain-producing counties. Additionally, the support system for factor integration should be enhanced, and differentiated policies encouraging entrepreneurship among migrant workers should be prioritized in core grain-producing areas and economically underdeveloped counties. This study provides empirical evidence to inform the development of differentiated policies for returning entrepreneurship of migrant workers in major grain-producing counties during the 15th Five-Year Plan period, thereby facilitating the promotion of common prosperity within these counties.

 摘要： On the basis of clarifying the connotation of agricultural new quality productivity and high-quality development, the value implication of new quality productivity empowering high-quality development through deconstructing traditional factor constraints, driving industrial level transitions, building a solid foundation for ecological modernization, and ensuring national food security is systematically explained. Currently, China has the practical foundation of technological innovation, talent support, facility elements, and policy systems. Based on this, a practical path should be constructed from the aspects of tackling core technological innovation and deepening scenario applications, reconstructing industrial spatial layout to optimize regional coordination, innovating green trading systems to accelerate ecological value transformation, and improving inclusive governance frameworks to ensure fair sharing of development dividends, providing theoretical reference for the construction of a strong agricultural country.

 摘要： This study focuses on the governance of groundwater over-exploitation in Xiaogan City, systematically analyzing the current status of over-exploitation, the implemented governance measures, and the effectiveness of the monitoring system. The findings indicate that comprehensive strategies, including law-based water management, enhancement of the monitoring network, strict enforcement of water drawing permits, optimization of water resource allocation, and promotion of a water-saving society, have contributed to a continuous rise in groundwater levels in Xiaogan City. Over the past decade, water levels in the center of the depression cone have risen by 4 m in the first aquifer and by 14 m in the second aquifer. The article also incorporates advanced technologies, including the “space-air-ground” integrated monitoring network and artificial intelligence-based prediction and early warning systems in the Haihe River Basin, alongside governance experiences from North China, to offer theoretical insights and practical guidance for developing groundwater over-exploitation governance and monitoring systems in comparable southern regions.

 摘要： Based on the data of conventional radiosonde observations, the new generation Doppler radar, FY-4B satellite, regional assimilation products, etc., a regional extreme rainstorm in Sanming City from 20:00 on June 12 to 20:00 on June 13, 2024 was analyzed from the aspects of weather conditions, circulation patterns, mesoscale evolution, and numerical model deviations. Through a horizontal comparison among the towns in Nanping, Sanming, and Longyan that experienced heavy precipitation during this process, as well as a vertical comparison with the rainstorm in Taining on May 8, 2016, the difficulties and indicators for forecasting warm-sector rainstorms in this region were summarized to provide a reference for the forecasting and warning of similar extreme warm-sector rainstorms in northwestern Fujian. The results show that the regional extreme rainstorm in Sanming City from 20:00 on June 12 to 20:00 on June 13, 2024 was characterized by concentrated precipitation and extreme short-term rainfall intensity. The cumulative rainfall in Xiaqu Town, Taining County was 264.7 mm, and the hourly rainfall intensity in Bailian Town, Jiangle County was 81.3 mm. Due to the combined influence of the southwest jet stream, low-level shear, and deep warm moist air flow, the superposition of a warm-sector rainstorm and train effect was the core cause of the disaster.

 摘要： Citrus medica is an important medicinal plant belonging to the genus Citrus in the Rutaceae family. Its fruit is rich in bioactive compounds such as flavonoids and coumarins, and has significant medicinal and economic value. However, during cultivation, C. medica often suffers from various adverse stresses, including pests, diseases, and abiotic factors, which significantly affect its yield and quality. This paper systematically reviews the research progress on the physiological and molecular response mechanisms of C. medica to these adverse stresses. The paper also explores the signal interactions between biotic and abiotic stresses, the trade-off of defense resource allocation, and comprehensive prevention and control strategies, including exogenous regulation, grafting, and intelligent monitoring. In light of current research challenges such as insufficient understanding of mechanisms, limited studies on multi-stress interactions, and delayed validation of key gene functions, it is proposed that future efforts should focus on strengthening multi-omics integrative analysis, gene-editing breeding, phenomics monitoring, and the development of green control technologies. These measures will provide theoretical foundations for stress-resistant breeding and the efficient cultivation of C. medica.

 摘要： This article reviews the latest research progress on acacetin: regarding cardioprotection, it mitigates myocardial ischemia-reperfusion injury and chronic heart failure by modulating the HMGB1/RAGE and GAS6/Axl pathways. In the liver, it alleviates alcoholic liver injury through antioxidant and anti-inflammatory mechanisms. In the nervous system, it improves depression-like behaviors by inhibiting the HIF-1α/NLRP3 pathway. In bones and joints, it ameliorates osteoarthritis by blocking the JAK/STAT pathway. Furthermore, it reduces acute lung injury by inhibiting the NLRP3 inflammasome and improves diabetic vascular endothelial dysfunction via the eNOS/PERK pathway. These findings provide a theoretical basis for the development and utilization of acacetin.

 摘要： [Objectives] To investigate the concentration of tea polyphenols in the tea infusion, evaluate their antioxidant and antibacterial activities, optimize the extraction conditions of tea polyphenols, and provide a foundation for their development as natural antioxidants and antibacterial agents. [Methods] Single-factor tests and orthogonal experiments were performed to examine the effects of brewing temperature, duration, and frequency on the extraction of tea polyphenols. Antioxidant activity was assessed using the DPPH radical scavenging assay, reducing power assay, and hydroxyl radical scavenging assay. The antibacterial activities of the tea infusion against Escherichia coli, Bacillus thuringiensis, Penicillium, and Saccharomyces were evaluated through spectrophotometry. [Results] The concentration of tea polyphenols increased with rising brewing temperature and duration but decreased with an increase in brewing frequency. The relative influence of these factors was ranked as follows: brewing duration> brewing frequency > brewing temperature. The optimal brewing conditions were determined to be 100 °C, 15 min, and a single brewing cycle. Under these conditions, the tea polyphenol concentration reached 0.788 4 mg/mL. Additionally, the DPPH free radical scavenging rate, reducing power, and hydroxyl radical scavenging rate of the tea infusion all exhibited a positive correlation with tea polyphenol concentration. The antibacterial activity of the tea infusion against four microorganisms, in descending order of efficacy, was B. thuringiensis, E. coli, Penicillium, and Saccharomyces. [Conclusions] The extract of Fenghuang Dancong tea exhibits significant antioxidant and antibacterial properties. Its efficacy is positively correlated with the concentration of tea polyphenols, demonstrating a stronger inhibitory effect on bacteria compared to fungi.

 摘要： [Objectives] To investigate the mechanism of lipoxygenase in responding to pathogenic stress in Physcomitrella patens induced by Botrytis cinerea. [Methods] It used wild-type and NDGA-treated Physcomitrella patens as experimental materials to measure the activities of phenylalanine ammonia-lyase (PAL), chalcone synthase (CHS), and cinnamyl alcohol dehydrogenase (CAD), as well as the contents of SA, ABA, and ET after inoculation with Botrytis cinerea (0, 6, 12, 24, 48, 72 h). [Results] In wild-type plants inoculated with B. cinerea, the activities of CHS, PAL, and CAD increased during the early defense stage compared with the control (uninoculated wild-type). In NDGA-treated P. patens inoculated with B. cinerea, the levels of CHS, PAL, and CAD were lower than those in wild-type plants at the corresponding time points after inoculation, indicating a correlation between LOX activity and the changes in CHS, PAL, and CAD activities during early defense. The contents of SA, ABA, and ET in wild-type plants inoculated with B. cinerea were higher than those in the control (uninoculated wild-type). In NDGA-treated P. patens inoculated with B. cinerea, the levels of SA, ABA, and ET were lower than those in wild-type plants at the corresponding time points after inoculation, suggesting that the synthesis of SA, ABA, and ET is correlated with LOX activity during early defense. [Conclusions] This study will lay a foundation for further molecular-level research on the disease resistance mechanisms of LOX in bryophytes.

 摘要： [Objectives] To explore the mechanism of Atractylodes lancea in the treatment of chronic pancreatitis (CP). [Methods] The network pharmacology and molecular docking techniques were applied. The active components of A. lancea were screened through the TCMSP database, and the potential targets of A. lancea were predicted using the SwissTargetPrediction database. Disease-related targets of chronic pancreatitis were collected from the GeneCards and OMIM databases. Cytoscape software was used to construct and analyse the “drug component–target” network. The intersecting targets between the active component targets of A. lancea and CP-related targets were identified, and a protein–protein interaction (PPI) network was constructed and analysed using the STRING database and Cytoscape software to obtain the core targets. GO functional enrichment analysis and KEGG pathway enrichment analysis of the intersecting targets were performed using RStudio software. Finally, AutoDock Tools software was employed to validate the molecular docking between the major active components and the core targets. [Results] A total of 9 active components of A. lancea, 279 component-related targets, 1 160 disease-related targets, and 94 intersecting drug-disease targets were identified. The core genes involved in the treatment of CP by A. lancea mainly included IL6, TNF, STAT3, TP53, and EGFR. The major signalling pathways included the PI3K-Akt signalling pathway, lipid and atherosclerosis, and proteoglycans in cancer. The intervention of A. lancea in CP involves a complex biological process with multiple targets and pathways. [Conclusions] This study elucidates the mechanism of A. lancea against CP from the perspectives of multi-component and multi-target actions, and provides a theoretical basis as well as directions for subsequent molecular biological experiments.
