Plenty of studies have shown that individuals who reported more adverse childhood experiences (ACEs) were more likely to commit dating violence (DV) than those who reported fewer ACEs. However, the underlying mechanism of the relationship remains understudied. Given that an individual's self-esteem is associated with both ACEs and DV behavior, this study aimed to explore the mediating role of self-esteem in the ACE-DV relationship. Cross-sectional research was conducted using a survey sample of 319 university students (177 with ACEs, and 142 without ACEs) from different universities located in different regions in China. Nearly half of the participants (41.4%) perpetrated DV in the past year, and more than half of the participants (55.5%) experienced at least one type of ACEs. The results showed that the direct effects of cumulative ACE and three subdimensions of ACEs (i.e., child maltreatment, family dysfunction, and socio-community adversity) on DV perpetration were statistically significant. Moreover, self-esteem partially mediated the relationships between cumulative ACE, as well as two subdimensions (child maltreatment and socio-community adversity), and DV perpetration. Self-esteem did not mediate the relationship between family dysfunction and DV perpetration. These results implied that children who had more ACEs were more likely to develop lower self-esteem, which may increase the likelihood of perpetrating DV in adulthood. Considering the findings, the urgency to involve community-based organizations in identifying children at high risk and improve the mandatory reporting system of child maltreatment in China is discussed. Also, the importance of early intervention in self-esteem building among children with ACEs, and implications for curbing dating violence in the university setting are discussed.

ABSTRACTIn recent years, multiple regions in China have experienced an increase in the occurrence of enzootic nasal tumour virus type 2 (ENTV‐2) infections. This research highlights the initial full genomic sequence of ENTV‐2 isolated from Guizhou, a province in southwest China. The newly identified strain GZZY1, which belongs to the ENTV‐2, had its complete genome analysed and found to be 7504 base pairs in length. Based on a phylogenetic analysis, GZZY1 has been classified as part of the potential sublineage 1.6. Additionally, recombination analysis indicates that GZZY1 may be a recombinant strain, with the gag and env genes serving as the recombination sites, likely originating from sublineages 1.5 and 1.2. In conclusion, this study presents the genomic analysis of GZZY1, a novel ENTV‐2 strain isolated from the Guizhou region of China, providing new information about the evolutionary structure and recombination potential of the virus in China. Our findings provide insights into the genetic makeup and potential variations of ENTV‐2 in China, which could enhance our understanding of its evolutionary patterns.

In the context of global warming and increasing drought, clarifying intraspecific variation in plant xylem hydraulic traits and their ecological adaptation strategies is crucial for predicting vegetation stability and functional maintenance in arid ecosystems. This study investigated Reaumuria songarica, a widely distributed and highly drought-tolerant shrub native to the desert regions of northwestern China. By integrating quantitative anatomical analyses of xylem vessels and inter-vessel pits with trait network modelling, we systematically assessed the variation patterns and environmental responses of its hydraulic structural traits along an aridity gradient. The results demonstrated that: (1) R. songarica exhibits substantial intraspecific variation in hydraulic traits, with individuals in hyper-arid regions possessing larger pit aperture areas and higher pit densities, indicative of an "opportunistic" water-use strategy that facilitates rapid responses to episodic rainfall events; (2) different traits exhibited distinct responses to temperature, precipitation, and soil conditions, with tissue-level traits being more responsive to temperature, while pit-level traits were primarily influenced by precipitation and soil factors; (3) vessels and pits displayed significant coordinated variation at the anatomical level. Trait network analysis further revealed that the topological structure of hydraulic traits was substantially reorganized along the aridity gradient, transitioning from a highly coordinated strategy centered on embolism resistance in arid regions to a structure-stabilization strategy centered on vessel wall thickness in hyper-arid regions. This study provides clear evidence of intraspecific variation in pit structure in R. songarica and uncovers the coordinated regulatory mechanism between pit and vessel structures. These findings offer microstructural insights into hydraulic adaptation strategies in desert plants and contribute theoretical support for drought-tolerant shrub selection and ecological restoration in arid regions.

Brucellosis, a neglected zoonotic disease as defined by the World Health Organization (WHO), represents a substantial burden, causing both severe human morbidity and significant economic losses to the livestock industry. In recent years, the Ningxia Hui Autonomous Region (Ningxia) in northwest China has emerged as a region with persistently high endemicity of human brucellosis. An in-depth analysis of the epidemic's prevalence and spatiotemporal evolution in this region is essential to inform the optimization of targeted prevention and control measures. Data on all human brucellosis cases from 2010 to 2024 were collected from the China Information System for Disease Control and Prevention. Temporal trends, global and local spatial autocorrelation, and spatial scan statistics were used to explore temporal patterns, regional clustering, and high-risk areas. A total of 35 665 human brucellosis cases were reported in Ningxia, with no associated deaths, during the study period. The average annual incidence rates was 35.08/100,000, ranging from 3.31 to 84.80 per 100,000. Two incidence peaks were observed: the first in 2015 (43.66/100,000) and the second in 2022 (84.80/100,000). The human brucellosis incidence rates showed that overall increasing trend from 2010 to 2024 (average annual percentage change [AAPC]=18.31%, but this was not statistically significant (t = 1.63, P = 0.102). Male accounted for 71.01% (25 325 cases) of all cases, 2.45 times higher than females (28.99%, 10 340 cases). Cases were reported in all 22 counties of Ningxia. The top five counties with the highest average annual incidence were: Yanchi County (184.79/100,000), Tongxin County (75.91/100,000), Zhongning County (46.47/100,000), Xiji County (46.15/100,000) and Yuanzhou District (45.30/100,000), while Xingqing District had the lowest rate (5.60/100,000). The top five counties with the fastest AAPC were: Huinong District (AAPC = 140.46%), Qingtongxia City (AAPC = 127.19%), Pengyang County (AAPC = 111.19%), Haiyuan County (AAPC = 107.97%) and Lingwu County (AAPC = 102.04%). Global spatial autocorrelation analysis revealed spatial clustering of human brucellosis incidence between 2022-2024 (Moran's I 0.266, p = 0.033; 0.394, p < 0.001; 0.353,p = 0.002, respectively). Local spatial autocorrelation identified "high-high" clusters primarily in Zhongning County, Tongxin County and Lingwu County. Additionally, spatial scanning analysis detected four spatial clusters, including one most likely cluster (LLR = 6474.66, RR = 3.71, P ( 0.001) and three secondary clusters. The primary cluster center was located at Jingyuan County (38.10°N, 106.34°E), with a cluster radius of 271.44 km. Our findings reveal a substantial burden of human brucellosis in Ningxia. The disease exhibits distinct seasonality, peaking in summer and autumn. Priority interventions should include: (1) Enhanced health education and targeted behavioral interventions for middle-aged and elderly males to improve personal awareness and competency in prevention and control; and (2) Timely identification of key risk factors and implementation of tailored prevention strategies in regions experiencing either a rapid increase or persistently high incidence.

Against the backdrop of global warming, the imbalance in agricultural carbon budgets poses a dual threat to ecological security and food security. As a major grain-producing region in China, Hunan Province is confronted with substantial CH4 emissions derived from rice cultivation, a problem further exacerbated by industrialization, urbanization, and shifts in farming practices. Consequently, investigating the carbon imbalance in Hunan's agricultural cultivation is of great significance for advancing the sustainable development of agriculture in the province. This study constructs and quantifies the agricultural carbon imbalance index (CII), and employs exploratory spatiotemporal data analysis, the PLS-VIP method, and the GTWR model to analyze the spatiotemporal evolution and driving factors of agricultural cultivation carbon imbalance of Hunan Province in China from 2001 to 2022. (1) The CII for agricultural cultivation in Hunan Province decreased from 0.41 in 2001 to 0.26 in 2022. Its spatiotemporal pattern shifted from "high in the north and low in the south" to "high in the west and low in the east," with the gravity center of CII moving southwestward. (2) Over the study period, the spatial correlation characteristics of CII underwent three stages: significant positive correlation, random distribution, and weak positive correlation. LISA time path and spatiotemporal transition analyses showed that the spatiotemporal clustering pattern of CII remained relatively stable from 2001 to 2011; however, its stability weakened slightly from 2012 to 2022. (3) Key factors influencing the agricultural cultivation CII in Hunan Province include GPA, GST, IARDF, PAOV, FUI, and PUI. These factors exhibit significant spatiotemporal heterogeneity in their effects. For example, the FUI and PUI had significant impacts on CII in the Xiangbei region, whereas their influence was relatively weaker in the Xiangxi region. To alleviate the persistent carbon imbalance in Hunan's agricultural cultivation systems, differentiated carbon sequestration and emission reduction strategies should be formulated by integrating the significance hierarchy of CII drivers and their spatial heterogeneity patterns. Special emphasis ought to be placed on tackling the re-emergence of carbon imbalance in specific municipal regions, which stems from urban expansion encroaching on farmland and the persistence of traditional cultivation practices. This targeted optimization will effectively facilitate the sustainable and low-carbon development of Hunan's agricultural sector.
