Prognostic factors of oropharyngeal minor salivary gland carcinoma in Southern China: a long-term follow-up observational study.

Bryophytes are essential components of urban biodiversity but remain understudied in subtropical cities. This study investigates bryophyte diversity across three urban green space types: parks, affiliated green spaces, and street plantings along urban-rural gradients in Guangzhou, southern China. We surveyed 36 sample sites and employed a boosted regression tree model to analyze the relationships between bryophyte diversity and environmental variables, including soil physicochemical properties, canopy density, precipitation, and anthropogenic disturbance. Twenty-two bryophyte species were recorded, with Sematophyllaceae and Hypnaceae as the dominant families. Key environmental drivers of bryophyte diversity were ranked as follows: human disturbance > canopy density > vascular plant diversity > site elevation > soil properties. Conservation strategies should focus on minimizing anthropogenic impacts, enhancing vascular plant diversity, and maintaining moderate canopy cover.

Neonicotinoids (NEOs) are widely used insecticides in agriculture and household pest control and have raised concerns due to their potential adverse effects on pollinator populations. NEOs can be transferred to bees during pollination and subsequently accumulate in honey, making their presence in honey of particular concern, especially in China, the world's largest honey producer. In this study, NEO levels were investigated in 86 honey samples collected from different regions of China. Among the six target NEOs, dinotefuran (DIN) showed the highest detection frequency (95.35%), while clothianidin (CLO) exhibited the highest mean concentration (7.010 μg/kg). For neonicotinoid metabolites (mNEOs), 1-methyl-3-(tetrahydro-3-furylmethyl) guanidine (DIN-G) had the highest detection rate (82.56%), and 6-chloronicotinic acid (6-CNA) showed the highest average concentration (6.640 μg/kg). Regional analysis revealed significantly higher NEO contamination in honey from southern China compared with other regions. In addition, lychee honey and polyfloral honey contained higher NEO residue levels than other honey types. Health risk assessment based on hazard quotient (HQ) and hazard index (HI) indicated that dietary exposure to NEOs through honey consumption is unlikely to pose significant health risks to consumers. This study compared NEOs residues in honey from different regions and honey types and found significantly higher NEOs concentrations in honey from southern China. Health risk assessment indicated that dietary exposure to NEOs through honey consumption is unlikely to pose significant adverse effects on human health, providing a scientific basis for market regulation and future research. © 2026 Society of Chemical Industry.

Understanding the spatial variability and environmental drivers of soil organic carbon (SOC) is critical for improving carbon management in fragile karst landscapes. This study collected 110 topsoil samples across county Yangshan, southern China, and applied an interpretable machine learning framework combining Random Forest (RF) and SHapley Additive exPlanations (SHAP) to explore the spatial heterogeneity and key environmental controls of SOC. The measured contents ranged from 3.33 to 44.20 g/kg, with a coefficient of variation of 43.5%, indicating moderate variability. RF-based spatial predictions revealed that higher SOC levels were mainly concentrated in the northern and southern subregions associated with clastic rocks, while lower SOC values clustered in central areas dominated by carbonate bedrocks. SHAP analysis indicated that soil physicochemical properties contributed over 53% to SOC, with total nitrogen and cation exchange capacity exerting the strongest influences, particularly in karst zones. Hydrological, vegetation, and terrain-related factors showed moderate importance, especially in high-elevation areas with natural vegetation and complex topography that promoted SOC accumulation. In contrast, climatic variables had relatively weak impacts, with their influences clustered in lowlands dominated by anthropogenic land uses. These findings revealed spatially heterogenous controls on SOC between karst and non-karst landscapes, emphasizing the dominant role of soil properties under shallow, erosion-prone conditions and highlighting the role of topography and vegetation in enhancing SOC stocks in mountainous areas. The integrated use of interpretable machine learning approaches improves the understanding of localized SOC dynamics and provides a valuable reference for precision carbon management and ecological restoration in other environmentally sensitive regions. • RF-SHAP framework effectively identified key environmental drivers on SOC. • Local SHAP values visualized spatial heterogeneity in karst and non-karst areas. • TN and CEC dominated contributions of SOC, especially under karst landscapes. • Hydrology, vegetation, and terrain influenced SOC in high-elevation clastic zones. • Climatic impacts clustered in lowlands associated with anthropogenic disturbance.

Emerging genomic evidence suggests that non-mutagenic promoters shape the global distribution of esophageal squamous cell carcinoma (ESCC). One suspected promoter is a group of minuscule needle-shaped glass fragments as outgrowths on edible weeds, millet bran, and wheat bracts, which in a bolus of food could scarify a narrowed gullet in high-risk regions of South Africa, Iran, and northern China. Repeated injuries and chronic inflammation of esophageal epithelium caused by these glass needles are analogous to cosmetic micro-needling in dermatology-stimulating collagen and elastin via wound-healing cascades. While tumors can be unhealed wounds and siliceous "micro-needles" from wheat bracts have been linked to the high ESCC risk in wheat-based eaters in semi-arid northern China, we here report abundant needle-shaped diatom frustules (siliceous cell walls of diatoms, aka "glass boxes") in trash fish-related food samples from high-ESCC regions of coastal southeastern China. Through a preliminary feeding trial conductedon rats, we found that needle-shaped diatom frustules may be more likely to lodge in the esophageal epithelium of rodents than round-shaped ones. Diatom needle contaminants in the diet may underlie the ESCC epidemic in coastal southeastern China, where dietary culture allows the guts of trash fish to enter human food.
