Biodiversity serves as the foundation for human survival and development. Marine fishes play a crucial role in supporting both global biodiversity and food sources. The conventional methods for fish diversity and fishery resources survey are inadequate to meet the growing demand for large-scale and long-period surveys. The eDNA metabarcoding approach provides an effective and non-invasive monitoring revolution, and has been applied to identify fish diversities. This study conducted a comprehensive comparison of fish diversity in the East China Sea on a large scale both horizontally and vertically. The results showed a total of 81 fish species, which were classified into 20 orders, 44 families and 72 genera. Although no statistically significant difference in fish diversity was found amongst the horizontal groups (east-middle-west, south-middle-north, and shallow-middle-deep) and the various sampling layers (surface-middle-bottom), discernible trends were obtained in this study. Fish diversity results revealed the orders of east > middle > west, middle > north > south and deep > shallow > middle in horizontal groups. Additionally, surface water exhibited a higher level of fish diversity than other water layers. Some fish species were only detected at specific vertical depths. The diverse composition of fish species across different water layers can be attributed to their distinct ecological types. The overall findings suggest that an increase of sampling stations and mixed samples should be collected in deeper water bodies for comprehensive understanding of fish diversity. This study can also provide the fundamental data and experimental design reference for future studies and fishery management. [ABSTRACT FROM AUTHOR]

Objective: An exploration of the influence of probiotics combined with immune checkpoint suppressors and chemotherapeutic agents on digestive system function, intestinal immunity and prognosis in patients with metastatic colorectal carcinoma. Methods: This was a quasi-experimental study. During March 2019 to March 2020, 96 patients with metastatic colorectal carcinoma were arbitrarily classified into control group (n = 48) and intervention group (n = 48). The control group received only immune checkpoint inhibitors or chemotherapy, while the intervention group received immune checkpoint inhibitors or chemotherapy, plus probiotic therapy. Survival and complication rates after 6 months, 12 months and 2 years of treatment were calculated. Intestinal barrier function, immune function and quality of life were analyzed before and after treatment. Results: Ninety-six patients were recorded at the follow-up demonstrating superior survival in the intervention group after 6 months, 12 months and 2 years of therapy. D-lactate and diamine oxidase (DAO) levels were elevated in the intervention group after treatment, with smaller elevations (P < 0.05). The levels of Bifidobacterium and Lactobacillus were remarkably higher in the intervention group after treatment compared to the control group prior to and following therapy (P < 0.05). The amount of Enterococcus and Escherichia coli in the intervention group after treatment was obviously lower compared to the pre-treatment and control groups (P < 0.05). CD3+, CD4+, and CD4+/CD8+ levels were found to be higher in the intervention group (P < 0.05), while CD8+ levels were reduced in the intervention group (P < 0.05). All dimensions of the QLQC-30 scale were higher in the intervention group (P < 0.05). The incidence of complications such as nausea and vomiting, loss of appetite, bloating and diarrhea was considerably reduced in the intervention group (P < 0.05). Conclusion: Immune checkpoint suppressors combined with chemotherapeutic agents or probiotic regimens can obviously enhance the prognosis of patients with metastatic colorectal carcinoma. This combination therapeutic strategy can balance the imbalanced intestinal flora, improve intestinal function, and lessen the incidence of adverse events, so it is worthy of clinical application and can lessen the incidence of adverse reactions.

ADAR is highly expressed and correlated with poor prognosis in hepatocellular carcinoma (HCC), yet the role of its constitutive isoform ADARp110 in tumorigenesis remains elusive. We investigated the role of ADARp110 in HCC and underlying mechanisms using clinical samples, a hepatocyte-specific Adarp110 knock-in mouse model, and engineered cell lines. ADARp110 is overexpressed and associated with poor survival in both human and mouse HCC. It creates an immunosuppressive microenvironment by inhibiting total immune cells, particularly cytotoxic GZMB+CD8+ T cells infiltration, while augmenting Treg cells, MDSCs, and exhausted CD8+ T cells ratios. Mechanistically, ADARp110 interacts with SNRPD3 and RNPS1 to stabilize CD24 mRNA by inhibiting STAU1-mediated mRNA decay. CD24 protects HCC cells from two indispensable mechanisms: macrophage phagocytosis and oxidative stress. Genetic knockdown or monoclonal antibody treatment of CD24 inhibits ADARp110-overexpressing tumor growth. Our findings unveil different mechanisms for ADARp110 modulation of tumor immune microenvironment and identify CD24 as a promising therapeutic target for HCCs. [ABSTRACT FROM AUTHOR]

Background: Lead is a prevalent heavy metal pollutant in the environment, and chronic lead exposure in occupational settings has been linked to cognitive decline. Our objective was to delineate lead-induced changes in brain functional activity through the assessment of regional homogeneity (ReHo), degree centrality (DC) and seed-based functional connectivity (FC) using resting-state functional magnetic resonance imaging (rs-fMRI). Methods: In this cross-sectional study, we recruited 76 participants from a smelting company. Based on their blood lead levels, 26 participants were assigned to the lead exposure group (≥ 300 μg/L), whereas 23 were assigned to the control group (≤ 100 μg/L). Neuropsychological assessments included the Montreal Cognitive Assessment, Mini-Mental State Examination, Self-rating Anxiety Scale, and Self-rating Depression Scale. Participants underwent rs-fMRI for ReHo, DC, and FC analyses. Brain regions demonstrating significant differences in ReHo and DC were identified as regions of interest for subsequent FC analysis. We also examined the relationships between lead levels, FC values, and neuropsychological scores. Results: Compared to the control group, individuals with high lead exposure exhibited increased ReHo in the bilateral insula and vermis and elevated DC in the left olfactory cortex. Notably, the left insula demonstrated reduced FC with the right cerebellar crus I, left fusiform gyrus, left superior frontal gyrus, and left middle frontal gyrus. The right insula also displayed reduced FC with the right middle frontal gyrus but increased FC between the left olfactory cortex and right insula. Furthermore, negative correlations were observed between lead levels and FC of the left insula with the left fusiform gyrus (r = − 0.586), left superior frontal gyrus (r = − 0.556), and left middle frontal gyrus (r = − 0.626), as well as between FC of the right insula and the right middle frontal gyrus (r = − 0.587). Conversely, there was a positive association between FC of the left olfactory cortex with the right insula and lead levels (r = 0.609), whereas an inverse relationship was noted with neurocognitive assessments. Conclusions: The disruption in insula coordination may significantly impair long-range FC and contribute to cognitive deficits resulting from lead exposure. The insula appears to be a pivotal region in lead-associated neurocognitive impairment. [ABSTRACT FROM AUTHOR]

Poplar is an important tree species for timber supply and ecological protection in northern China. Cultivating and selecting high-quality varieties and germplasm resources suitable for cultivation are key factors in enhancing the quality and productivity of poplar plantations in the arid and semi-arid northern regions with shorter growing seasons. This study conducted a field cultivation experiment on 10 progeny clones from the direct cross (D × M) of imported Populus deltoides 'DD-109' with Populus maximowiczii and 7 progeny clones from the reciprocal cross (M × D) using one-year-old rooted cuttings planted at a 4 m × 8 m spacing. Based on 17 years of annual growth observations, the study systematically compared growth characteristics, age of quantitative maturity, path relationships between traits, and early selection efficiency in the hybrid offspring. The results indicated that the D × M population had superior diameter at breast height (DBH), tree height (H), and volume (V) compared to the M × D population, while the height-to-diameter ratio (HDR) was lower. The growth rate of the 17 clones peaked from 10 to 14 years, with annual volume growth increments (PAIs) higher than mean annual volume increments (MAIs) during the early growth stages; the quantitative maturity age ranged between 12 and 16 years. The D × M population generally reached quantitative maturity earlier than the M × D population, with the fastest clone maturing in 12 years. Four clones (DM-9-17, DM-9-18, DM-9-14, and MD-61) showed values for V, DBH, H, and HDR above the hybrid group average. Path analysis demonstrated that DBH had the most significant direct and indirect effects on V, suggesting it as the best predictor for V. Using DBH as a reference, correlation and early selection efficiency analysis showed a strong relationship between growth characteristics at planting years 4–5 and later-stage performance, indicating this as the optimal period for early selection. These findings contribute to evaluating the production potential of P. deltoides 'DD-109' and P. maximowiczii germplasm in northern China and provide valuable guidance for selecting poplar clones suitable for local cultivation, accelerating breeding processes, and informing management planning for poplar plantations.

Neutrophil extracellular traps (NETs) formation is a key process in inflammatory diseases like gout, but the underlying molecular mechanisms remain incompletely understood. This study aimed to establish a model to examine the formation of NETs induced by monosodium urate (MSU) and phorbol 12-myristate 13-acetate (PMA) and to elucidate their molecular pathways. Laser confocal microscopy was used to visualize NET formation, while flow cytometry was employed to detect reactive oxygen species (ROS) production. The microstructure of neutrophils was observed by transmission electron microscopy, and the expression of key proteins was determined by Western blotting. Additionally, the effect of various inhibitors targeting the MAPK signaling pathway on NET formation was evaluated. They include the Ras inhibitor Salirasib, Raf inhibitor Vemurafenib, ERK inhibitor PD98059, and p38 MAPK inhibitor SB203580, as well as NADPH oxidase inhibitor DPI and neutrophil elastase inhibitor Alvelestat. The results showed that MSU and PMA triggered significant NET formation, which was accompanied by increased ROS levels, lactate dehydrogenase release, dsDNA, and IL-8. Notably, selective MAPK pathway inhibitors and DPI and Alvelestat, except for SB203580, effectively down-regulated these indicators. These data indicated that the activation of a signaling pathway involving Ras-Raf-ERK, which is dependent on ROS, is crucial for the induction of NET formation by MSU and PMA. Given the involvement of NETs in multiple pathologies, our findings could potentially serve as molecular targets for the intervention and treatment of crystal-related diseases, especially for gout.

Background: NAFLD is gaining recognition as a complex, multifactorial condition with suspected associations with endocrine disorders. This investigation employed MR analysis to explore the potential causality linking NAFLD to a spectrum of endocrine diseases, encompassing T1D, T2D, obesity, graves' disease, and acromegaly. Methods: Our methodology leveraged a stringent IV selection process, adhering to the STROBE-MR guidelines. The MR analysis was conducted utilizing three distinct methods: IVW, WM, and MR-Egger. The IVW method was prioritized as the primary analytical approach. We conducted MR analyses to analyze the causal relationship between NAFLD and metabolic disorders. We also examined 1400 metabolites implicated in NAFLD. Metabolic pathway analysis was performed using the MetaboAnalyst database. Results: The findings indicated that T2D (OR = 1.211, 95%CI: 0.836–1.585) and obesity (OR = 1.245, 95%CI: 0.816–1.674) are associated with an increased risk of NAFLD development. Further exploration into the the 1400 metabolites revealed that cys-gly and diacetylornithine are predictive of NAFLD, T2D, and obesity, whereas isovalerylcarnitine exhibited an inverse association, potentially inhibiting disease development. Metabolic pathways involving alanine, aspartate, and glutamate metabolism were identified as pivotal regulators in the pathophysiology of NAFLD, T2D, and obesity. Conclusion: The present study generated innovative viewpoints on the etiology of NAFLD. Our findings underscore the significant role of T2D and obesity in NAFLD pathogenesis through metabolic pathways, presenting opportunities for targeted therapeutic strategies and warranting further investigation.

Objectives: To assess the association between thyroid dysfunction and diabetic retinopathy (DR), a two-sample bidirectional Mendelian randomization (MR) study utilizing the Genome-wide Association Study (GWAS) database was conducted to investigate the causal relationship between these two variables. Methods: In this study, GWAS of 48,328,151 single nucleotide polymorphisms(SNP) in the European population from the IEU open GWAS database were utilized as genetic tools for investigating thyroid dysfunction. The total sample size for the study on hyperthyroidism was 460,499 (case group: 3557; control group: 456,942). The total sample size for hypothyroidism was 410,141 (case group: 30,155; control group: 37,986). In addition, the data on DR were extracted from the FinnGen Biobank, comprising a total sample size of 319,046 individuals (10,413 cases and 308,633 controls). For the forward MR analysis, hyperthyroidism and hypothyroidism were considered as exposures with DR as the outcome. Reverse MR analysis was conducted using DR as exposure and hyperthyroidism and hypothyroidism as outcomes. Methods: The main analytical approach employed inverse variance weighting(IVW), supplemented by MR-Egger, Weighted mode method, weighted median, and Simple mode. Cochran's Q test, MR-PRESSO, MR-Egger and leave-one-out analysis were used to evaluate the sensitivity and pleiotropy. Results: Two-sample bidirectional MR analysis revealed a significant association between the presence of hyperthyroidism and hypothyroidism and an increased risk of DR in the forward MR analysis (IVW: OR = 1.29, 95% [CI] = 1.12–1.49, P < 0.001; OR = 1.17, 95% CI = 1.10–1.25, P < 0.001). In the reverse MR analysis, DR was found to be associated with an elevated risk of developing hyperthyroidism and hypothyroidism (IVW: OR = 1.56, 95% CI 1.38–1.76, P < 0.001; OR = 1.41, 95% CI 1.25–1.59, P < 0.001). Furthermore, most supplementary MR methods also demonstrated statistically significant differences and exhibited effect sizes consistent with those obtained from IVW. The sensitivity analysis confirmed the relative reliability of our causal findings. Conclusions: Our findings provide genetic evidence supporting a bidirectional causal relationship between thyroid function and DR. [ABSTRACT FROM AUTHOR]

Background: Campylobacter species are zoonotic pathogens, and are considered to be the major foodborne pathogen that causes outbreaks and sporadic gastrointestinal illnesses both in developed and developing countries. In this study, the molecular typing and antimicrobial susceptibility profiles of Campylobacter jejuni and Campylobacter coli isolates from patients and raw meat between 2021 and 2022 in Huzhou were analyzed by using pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST) and antimicrobial susceptibility testing. Methods: From September 1, 2021 to December 31, 2022, a total of 342 fecal specimens from diarrheal patients at a sentinel hospital in Huzhou and 168 samples of raw meat products collected from farmers' markets and supermarkets, were subjected to Campylobacter isolation and identification. The agar dilution method was used to determine resistance of the Campylobacter isolates to eleven antibiotics. In addition, pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) were performed to compare their genetic relationships. Results: 78 Campylobacter isolates were recovered, comprising 58 isolates (74.36%, 58/78) of Campylobacter jejuni (34 patient isolates and 16 food isolates) and 20 isolates (25.64%, 20/78) of Campylobacter coli (6 patient isolates and 14 food isolates). Campylobacter has emerged as a predominant foodborne pathogen in the local region, with detection rate reached 11.70% among 342 diarrhea samples. The Campylobacter isolation rate in 168 raw meat was 22.62% (38/168), all originating from poultry meat, with chicken been the major source of infection (86.84%, 33/38). Both PGFE type and MLST data confirmed that Campylobacter stains circulating in Huzhou are genetically diverse, with Campylobacter jejuni isolates being more diverse than Campylobacter Coli. PFGE typing revealed 45 band patterns among 54 Campylobacter jejuni strains and 17 band patterns among 19 Campylobacter Coli strains. 50 Campylobacter jejuni strains from different sources were classified into 37 ST types, showing a dispersed distribution and encompassing over 12 clonal complexes (CCs), with CC-21 being the most prevalent CC (22.00%, 11/50). The distribution of ST types in the 18 Campylobacter Coli strains was relatively concentrated, with 83.33% (15/18) of isolates belonging to the CC-828. In this study, 2 groups of Campylobacter jejuni strains (PFGE J2-ST464 and PFGE J9-ST-2328) originated from humans and chickens showed high genetic homologies by comparing PFGE and MLST results. Besides, some disagreement between PFGE and MLST was observed for certain ST, indicating a weak correlation between PFGE and MLST for certain Campylobacter strains. Most of the Campylobacter isolates were highly resistant to nalidixic-acid, ciprofloxacin and tetracycline. The multiple antibiotic resistance of Campylobacter Coli (89.47%) is higher than Campylobacter jejuni (29.63%). Conclusion: Campylobacter is an important foodborne pathogen in both diarrheal patients and raw meat products in Huzhou City, exhibiting multiple antibiotic resistance and high level of genetic diversity.

Background: Vibrio parahaemolyticus has emerged as the leading cause of seafood-associated infections worldwide. Previous studies have shown that V. parahaemolyticus can be detected in both environmental and clinical samples. However, the molecular characteristics of V. parahaemolyticus isolated from these sources remain unknown. Results: This study examined 128 strains of V. parahaemolyticus isolated from clinical and environmental samples collected between 2020 and 2023 in Huzhou, China. We identified 73 serotypes; O10:K4, O3:K6, and O4:KUT were the dominant serotypes among clinical isolates. We examined the proliferation and motility of major epidemic strains from environmental and clinical samples. Genetic diversity and evolution were assessed by average nucleotide identity (ANI), phylogenetic tree construction, and multilocus sequence typing (MLST). Furthermore, we identified 13 novel sequence types (STs) among the environmental isolates, indicating that V. parahaemolyticus strains are widely distributed and evolve rapidly in the environment in Huzhou, China. We found 206 virulence genes among these isolates, indicating that environmental isolates possess numerous virulence genes. Additionally, we detected 4 strains carrying the tdh or trh gene, which may increase their pathogenicity. The prediction results of antibiotic resistance genes shown that environmental isolates may carry up to 104 resistance genes, compared to 30 in clinical isolates. Conclusions: We observed that the environmental serotypes of V. parahaemolyticus exhibit greater diversity compared to clinical isolates, which are predominantly concentrated in three major serotypes. Furthermore, a considerable genetic distance was found between most clinical and environmental isolates. Notably, some clinical isolates show a closer genetic proximity to environmental isolates. Additionally, the distribution of virulence genes, specifically T3SS and tdh, significantly differs among isolates from these two distinct sources. The prediction results for antibiotic resistance genes suggest that environmental isolates may harbor a broader spectrum of resistance genes. The findings of this study provide new insights into the phylogenetic relationships between V. parahaemolyticus strains from clinical and environmental sources, and they enhance the MLST database.

Hepatocellular carcinoma (HCC) often occurs in the context of fibrosis or cirrhosis. Methylation of histone is an important epigenetic mechanism, but it is unclear whether histone methyltransferases are potent targets for fibrosis‐associated HCC therapy. ASH1L, an H3K4 methyltransferase, is found at higher levels in activated hepatic stellate cells (HSCs) and hepatoma cells. To determine the role of ASH1L in vivo, transgenic mice with conditional Ash1l depletion in the hepatocyte cell lineage (Ash1lflox/floxAlbcre) or HSCs (Ash1lflox/floxGFAPcreERT2) are generated, and these mice are challenged in a diethylnitrosamine (DEN)/carbon tetrachloride (CCl4)‐induced model of liver fibrosis and HCC. Depleting Ash1l in both hepatocytes and HSCs mitigates hepatic fibrosis and HCC development. Multicolor flow cytometry, bulk, and single‐cell transcriptomic sequencing reveal that ASH1L creates an immunosuppressive microenvironment. Mechanically, ASH1L‐mediated H3K4me3 modification increases the expression of CCL2 and CSF1, which recruites and polarizes M2‐like pro‐tumorigenic macrophages. The M2‐like macrophages further enhance tumor cell proliferation and suppress CD8+ T cell activation. AS‐99, a small molecule inhibitor of ASH1L, demonstrates similar anti‐fibrosis and tumor‐suppressive effects. Of pathophysiological significance, the increased expression levels of mesenchymal ASH1L and M2 marker CD68 are associated with poor prognosis of HCC. The findings reveal ASH1L as a potential small‐molecule therapeutic target against fibrosis‐related HCC. [ABSTRACT FROM AUTHOR]

To investigate the pollution characteristics of polycyclic aromatic hydrocarbons (PAHs) indoors and outdoors and their influencing factors, PM2.5 samples were systematically collected from both environments in Jinan during the summer and autumn seasons. During the observation period, the concentration of ∑ 19PAHs was 18.57 ± 10.50 ng/m3 indoors and 23.79 ± 16.13 ng/m3 outdoors. Most PAHs exhibited indoor-to-outdoor (I/O) ratios less than 1, indicating that indoor PAHs were primarily derived from the infiltration of outdoor sources. Correlation analysis underscored the significant influence of temperature on both outdoor concentrations and I/O ratios of PAHs. By utilizing diagnostic ratios and principal component analysis (PCA), vehicle emissions were identified as the predominant source of outdoor PAHs. Our study found that the toxic equivalents of benzo[a]pyrene (TEQBaP) values exceeded the European Commission's standard of 1 ng/m3, with indoor values at 2.78 ng/m3 and outdoor values at 3.57 ng/m3. Moreover, the total incremental lifetime cancer risk (ILCRTotal) associated with exposure to PM2.5-bound PAHs surpassed the acceptable level of 10E-6, indicating potential adverse health effects. These results underscore the urgent necessity for more stringent regulatory measures to reduce PAH emissions. Additionally, our findings provide valuable insights into how environmental factors shape the relationship between indoor and outdoor PAHs. [ABSTRACT FROM AUTHOR]

Gastrointestinal bleeding is an important gastrointestinal complication among peritoneal dialysis patients and correlated with a higher risk of mortality. Increased uric acid levels are a significant complication for peritoneal dialysis patients and have been associated with an increased risk of hemorrhagic stroke. The objective of the present study was to investigate the relationship between serum uric acid levels and gastrointestinal bleeding in peritoneal dialysis patients. A total of 2498 peritoneal dialysis patients were recruited. Based on the optimal uric acid cutoff value, two groups of patients were divided. We constructed a propensity-score-matched population of 1762 patients by matching sex, age, and body mass index. Survival outcomes between the two groups were compared using adjusted Kaplan–Meier curves. We constructed the restricted cubic splines regression to assess the correlation between levels of uric acid and gastrointestinal bleeding. A multivariate Cox proportional hazards regression was performed to test whether higher levels of uric acid are an independent risk factor for gastrointestinal bleeding. We performed a forest plot to show interaction effects in different subgroups. According to restricted cubic splines regression, uric acid levels were positively correlated with the risk of gastrointestinal bleeding events. After adjusted different confounding factors, patients with high levels of uric acid were prone to experience gastrointestinal bleeding (HR 1.868, 95%CI 1.001–3.486). In subgroups, the interaction between higher levels of uric acid and utilizing proton pump inhibitors was significant (P for interaction = 0.034). Further research found that taking proton pump inhibitors could decrease the risk of gastrointestinal bleeding in peritoneal dialysis patients accompanied high levels of uric acid. The baseline high levels of uric acid are an independent risk factor for gastrointestinal bleeding in patients undergoing peritoneal dialysis. [ABSTRACT FROM AUTHOR]

Malnutrition and inflammation are associated with mortality in peritoneal dialysis (PD) patients. Serum albumin and non-high-density lipoprotein cholesterol (non-HDL-C) are independently associated with mortality in PD patients. Combining albumin and non-HDL-C with mortality may be more plausible in clinical practice. This retrospective cohort study included 1954 Chinese PD patients from 1 January 2009 to 31 December 2016. Kaplan–Meier curve was used to determine the relationship between albumin to non-HDL-C ratio and all-cause mortality. Cox regression analysis was applied to assess the independent predictive value while adjusting for confounding factors. Competitive risk analysis was used to examine the effects of other outcomes on all-cause mortality prognosis. In the 33-month follow-up period, there were 538 all-cause deaths. Kaplan–Meier analysis presented significant differences in all-cause mortality. Multivariate Cox regression showed that the risk of all-cause mortality was lower in the moderate group (9.36–12.79) (HR, 0.731; 95% CI, 0.593–0.902, p = 0.004) and the highest group (>12.79) (HR, 0.705; 95% CI, 0.565–0.879, p = 0.002) compared to the lowest group (≤9.36). Competitive risk analysis revealed significant differences for all-cause mortality (p < 0.001), while there was no statistical significance for other competing events. Low albumin to non-HDL-C ratio was associated with a high risk of all-cause mortality in PD patients. It may serve as a potential prognostic biomarker in PD patients. [ABSTRACT FROM AUTHOR]

Purpose: Systemic inflammation biomarkers, derived from routine blood tests, have been demonstrated to be associated with prognosis of patients undergoing peritoneal dialysis (PD). However, studies focusing on the comparisons of their role on predictive efficacy for prognosis of PD patient are limited and results are inconsistent. The purpose of this study was to evaluate the prognostic value of various systemic inflammation biomarkers and to identify the optimal one in PD patients. Patients and Methods: This longitudinal study involved 3,225 patients undergoing PD across China. The prognostic accuracy of systemic inflammatory biomarkers was evaluated using C-statistics. Independent prognostic biomarkers of outcomes were determined using multivariate Cox proportional hazards regression analysis. Results: During a 46-month follow-up, 829 (25.7%) patients died, with 458 (55.3%) deaths attributed to cardiovascular disease (CVD). The highest C-statistics were observed for the IBI, with 0.619 and 0.621 for all-cause and CVD mortality, respectively. The optimal threshold of the IBI for predicting prognosis in patients undergoing PD was 50.0. An elevated IBI was a significant independent predictor of all-cause mortality, with a 1-SD increase associated with higher risks of all-cause and CVD mortality. Participants in the upper two quartiles of IBI exhibited increased risks of all-cause mortality by 41.2% and 67.6%, respectively, compared to those in the lowest quartile. Similar results were observed for CVD mortality. Conclusion: The IBI is a superior prognostic indicator of survival and could be broadly applied for prognosis of patients undergoing PD. Elevated IBI is an independent risk factor for all-cause and CVD mortality. [ABSTRACT FROM AUTHOR]

Introduction: Long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has been shown to be involved in Parkinson's disease (PD) progression, but its mechanism needs to be further explored. Methods: Mice were injected with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to induce PD mice models, and BV2 cells were treated with lipopolysaccharides (LPS) to mimic PD cell models. MALAT1 expression and suppressor of cytokine signaling 3 (SOCS3) protein level were examined using quantitative real-time PCR and Western blot, respectively. Cell functions were tested by cell counting kit 8 assay and flow cytometry. The interaction between MALAT1 and SOCS3 was confirmed using RNA pull-down and RIP assays. Results: MALAT1 was upregulated in MPTP-induced PD mice and LPS-induced BV2 cells. Silencing of MALAT1 increased viability, while inhibiting apoptosis and inflammation in LPS-induced BV2 cells. Besides, MALAT1 enhanced the SOCS3 promoter methylation to decrease its expression by recruiting DNMT1, DNMT3A, and DNMT3B. Furthermore, SOCS3 knockdown eliminated sh-MALAT1-mediated the inhibition effect on LPS-induced BV2 cell injury. In vivo, MALAT1 silencing ameliorated neurological impairment and neuroinflammation in MPTP-induced PD mice. Conclusion: Our data revealed that MALAT1 worsened PD processes via inhibiting SOCS3 expression by increasing its promoter methylation. [ABSTRACT FROM AUTHOR]

Objectives: Our objective was to present the experience on prenatal diagnosis of 1p36 terminal deletion, and further delineated the fetal presentation of the syndrome. Material and methods: This was a retrospective analysis of three new prenatal cases with pure 1p36 terminal deletion detected by chromosome microarray analysis (CMA) at a single Chinese medical center. We also reviewed 11 published prenatal cases with similar deletion sizes. Clinical data of all cases including indications for invasive testing, sonographic findings, maternal factors, and pregnancy outcomes were reviewed and analyzed. Results: Three new cases with pure 1p36 terminal deletion were prenatal diagnosed by CMA, the sizes of the deletion were 1.3 Mb, 5.0 Mb, and 4.9 Mb respectively. All cases were detected because of abnormal ultrasound findings, including central nervous system (CNS) abnormalities, congenital heart disease (CHD) and fetal growth restriction. Two pregnancies were terminated, and one was live-born but died three months after birth. Conclusions: The 1p36 terminal deletion results in many clinical manifestations, but the specificity of clinical features are not high. Prenatal sonographic findings such as CNS, CHD may act as suggestive signs of 1p36 deletion or other microdeletion/duplication syndromes. [ABSTRACT FROM AUTHOR]

Background Village doctors, as gatekeepers of the health system for rural residents in China, are often confronted with adversity in providing the basic public healthcare services. Objective We sought to summarize the training contents, training method, training location, and training costs most preferred by village doctors in China and hope to provide evidence and support for the government to deliver better training in the future. Methods Eight databases were searched to include studies that reported on the training needs of village doctors in China. We undertook a systematic review and a narrative synthesis of data. Results A total of 38 cross-sectional studies including 35,545 participants were included. In China, village doctors have extensive training needs. "Clinical knowledge and skill" and "diagnosis and treatment of common disease" were the most preferred training content; "continuing medical education" was the most preferred delivery method; above county- and county-level hospitals were the most desirable training locations, and the training costs were expected to be low or even free. Conclusion Village doctors in various regions of China have similar preferences for training. Thus, future training should focus more on the training needs and preferences of village doctors.

Gelling properties are important functional characteristics of fish gelatin, which directly affects its application range and commercial value. Fish gelatin was modified with hyaluronic acid in different molecular weights in this work. The effect of hyaluronic acid on gelling properties and structural characteristics of fish gelatin was studied by rheometer, texture analyzer, infrared spectroscopy, and scanning electron microscope. The findings suggested that hyaluronic acid with different molecular weights decreased gel strength of fish gelatin, but significantly increased gelling temperature, melting temperature, and apparent viscosity of fish gelatin. Moreover, the higher molecular weight of hyaluronic acid, the greater changes in gelling properties of fish gelatin. When the molecular weight of hyaluronic acid was more than 1 800 kDa, gelling temperature, melting temperature, and apparent viscosity (η50) reached respectively 22.32 °C 32.48 °C, and 153 mPa·s, respectively. Hyaluronic acid slightly reduced gel strength of fish gelatin by less than 8.1% . The gelation dynamics analysis showed that regardless of molecular weight, hyaluronic acid could decrease the gel rate of fish gelatin and stabilize the gel network structure of fish gelatin. Infrared spectroscopy showed the FG-HA complex formation was mainly driven by electrostatic interaction, and the complex hindered the formation of hydrogen bond between molecular chains in fish gelatin. The scanning electron microscopy analysis showed that hyaluronic acid could effectively improve gel network structure in the composite colloid. Moreover, the FG-HA > 180W complex showed the most compact microstructure. This paper will provide a theoretical basis for improving functional properties and expanding the application of fish gelatin. [ABSTRACT FROM AUTHOR]

Background: Alzheimer's disease (AD), characterized by cognitive impairment and depression, is currently one of the intractable problems due to the insufficiency of intervention strategies. Diethyl butylmalonate (DBM) has recently attracted extensive interest due to its anti-inflammatory role in macrophages. However, it is still unknown whether DBM has a beneficial effect on cognitive deficits and depression. Methods: DBM was administrated to 5×FAD and C57BL/6J mice by intraperitoneal injection. Novel object recognition, Y-maze spatial memory, Morris water maze and nest building tests were used to evaluate cognitive function. Moreover, the tail suspension test, forced swimming test, open field test and the elevated plus maze test were used to assess depression. Transmission electron microscopy, Golgi-Cox staining, immunofluorescence, RT-qPCR and western blot were utilized to determine the neuropathological changes in the hippocampus and amygdala of mice. Results: Multiple behavioral tests showed that DBM effectively mitigated cognitive deficit and depression in 5×FAD mice. Moreover, DBM significantly attenuated synaptic ultrastructure and neurite impairment in the hippocampus of 5×FAD mice, paralleled by the improvement of the deficits of PSD95 and BDNF proteins. In addition, DBM decreased the accumulation of microglia and downregulated neuroinflammation in the hippocampus and amygdala of 5×FAD mice. Conclusion: This study provides evidence that DBM ameliorates cognitive deficits and depression via improvement of the impairment of synaptic ultrastructure and neuroinflammation, suggesting that DBM is a potential drug candidate for treating AD-related neurodegeneration.

Carbon emission reduction in the construction industry is vital for realizing sustainable development, and the development of the digital economy plays an important role in this process. The impact of the digital economy on reducing carbon emissions in the construction industry is empirically explored through econometric analyses on a sample of panel data from 30 provinces in China from 2012 to 2021. The empirical results show that developing a digital economy can significantly reduce the construction industry's carbon emission intensity. Additionally, this impact has a significant spatial spillover effect and can benefit the neighboring regions. The mechanism test shows that the digital economy can reduce carbon emissions by improving the technological level of the construction industry. Moreover, the inhibiting effects of the digital economy on carbon emissions in the construction industry vary across different regions. They are more pronounced in the eastern and western regions of low coal-consuming regions. These findings offer valuable insights for policymakers to help drive the deeper integration of the digital economy with the construction industry and facilitate its transition to low-carbon development.

Background: To investigate corneal higher-order aberrations (HOAs) and choroidal characteristics in myopic individuals and explore the association between HOAs and choroidal parameters. Methods: Myopic participants were categorized into three groups based on axial lengths (ALs). We compared corneal HOAs, including spherical (Z40), comatic (Z3− 1 and Z31), and trefoil (Z3− 3 and Z33) aberrations, as well as choroidal vascularity index (CVI) and choroidal thickness (CT). Linear regression analysis was used to assess the relationships among corneal HOAs, CVI, CT, spherical equivalent, and AL. Results: Groups 1, 2, and 3 included 105, 98, and 118 eyes, respectively. Group 3 exhibited lower spherical HOA root mean square and Z40 values than group 1(p < 0.05). Group 1 showed lower Z31 levels than other groups (p < 0.001). Groups 1 and 2 had higher mean, central, and I2 vertical CVIs than group 3 (p < 0.05). Group 1 had a larger vertical S1 CVI than group 3 (p < 0.05). Group 3 had smaller horizontal CVI values in all regions except N2 (p < 0.05). Both the mean and CT in all regions decreased as AL increased (p < 0.001). The comatic (Z31) and trefoil (Z33) components were predictors of mean horizontal CVI, and the comatic (Z31) component was correlated with both mean vertical and horizontal CT. Conclusion: Longer AL myopic patients exhibited lower absolute values of spherical aberration and horizontal coma. Alterations in choroid in myopic patients correlated with corneal HOAs. Our results suggest a potential connection between the optical quality and ocular perfusion in myopia. [ABSTRACT FROM AUTHOR]

This work evaluated the alterations in the levels and types of polycyclic aromatic hydrocarbons (PAHs) within both liquid and solid products throughout the process of the catalytic supercritical water gasification of dewatered sewage sludge to examine the catalytic effect of various catalysts and the inhibit reaction pathways. The addition of Ni, NaOH, Na2CO3, H2O2, and KMnO4 reduced the concentrations of PAHs, with Ni and H2O2 showing the best performance. The concentrations of PAHs, especially higher-molecular-weight compounds in the residues, decreased sharply as the H2O2 amount increased. At a 10 wt% H2O2 addition, the levels of PAHs in the liquid and solid products were reduced by 91% and 88%, respectively. High-ring PAHs were not detected in the residues as the H2O2 amount increased to an 8 wt%. H2O2 addition evidently inhibits PAH formation by promoting the ring-opening reactions of initial aromatic compounds in raw sludge and inhibiting the polymerization of open-chain intermediate products. The addition of NaOH + H2O2 or Ni + H2O2 as combined catalysts significantly lowered PAH concentrations while increasing the H2 yield. The addition of 5 wt% Ni + H2O2 reduced PAH concentrations in the liquid and solid residues by 70% and 44%, respectively, while the H2 yield escalated from 0.13 mol/kg OM to 3.88 mol/kg OM. Possible mechanisms associated with the reaction pathways of these combined catalysts are proposed. [ABSTRACT FROM AUTHOR]

The efficient utilization of organic solid waste resources can help reducing the consumption of conventional fossil fuels, mitigating environmental pollution, and achieving green sustainable development. Due to its dual nature of being both a resource and a source of pollution, it is crucial to implement suitable recycling technologies throughout the recycling and upgrading processes for plastics and biomass, which are organic solid wastes with complex mixture of components. The conventional pyrolysis and hydropyrolysis were summarized for recycling plastics and biomass into high‐value fuels, chemicals, and materials. To enhance reaction efficiency and improve product selectivity, microwave‐assisted pyrolysis was introduced to the upgrading of plastics and biomass through efficient energy supply especially with the aid of catalysts and microwave absorbers. This review provides a detail summary of microwave‐assisted pyrolysis for plastics and biomass from the technical, applied, and mechanistic perspectives. Based on the recent technological advances, the future directions for the development of microwave‐assisted pyrolysis technologies are predicted. [ABSTRACT FROM AUTHOR]

[Objective] This study investigated the growth conditions and fruit traits of different jujube varieties introduced to southern Xinjiang and selected the best varieties suitable for local jujube production. [Method] One-year-old branches of 17 excellent fresh jujube varieties in China were selected as scions, and 5-year-old gray jujube was selected as rootstock for introduction tests in Aksu, Xinjiang. By comparing the phenological period, tree growth potential (grafting survival rate, tree growth amount and dendritic force), fruit results (fruit lifting rate, fruit cracking rate, fruit mass, fruit uniformity and edible rate) and fruit quality (appearance color, flesh taste and flavor and main nutrient contents), 9 varieties with good taste, flavor and nutrient contents were initially screened. According to contents of soluble solid, VC, titrable acid and soluble sugar, single fruit mass, edible rate, fruit shape index and fruit uniformity, these varieties were scored by grey correlation method. [Result] After the introduction to southern Xinjiang, the phenological periods were quite different among varieties, which included 2 very early maturing varieties, 5 early maturing varieties, 9 medium maturing varieties and 1 medium late maturing variety. The graft survival rates of all varieties were higher than 65%. Jinggudazao, Fucuimi, Lengbaiyu and Yujiao trees had large growth amounts, strong branching force and prosperous growth. In the second and third years of grafting, fruit lif-ting rates of all varieties were relatively stable and consistent, and Zaocuimi and Luzao 5 had higher rate. Fruit cracking rates of Jingzao 28 and Jingzao 60 were 20. 57% and 23. 83%, respectively. Single fruit mass was very different among verities, ranging from 4. 22 to 26. 18 g, and the single fruit masses of most varieties were higher in the third year than in the second year. The fruit uniformity was 46. 63% to 79. 41%, and the edible rates were 91. 67% to 98. 76%. The fruit appearance was different among varieties, mainly in oval, oblong and inverted oval shapes. The fruit size was also greatly different with light red or red color. In the second year (2021), Jinsi 4 had the highest content of soluble solids of 38. 33%. The soluble sugar contents of Zaocuimi, Fucuimi and Jinsi 4 were higher than 29%. The titrable acid contents of Jingzao 18 and Yulu were above 1. 41%. The VC contents of Yujiao, Luzao 5 and Jinggudazao were higher than 400 mg/hg. According to the taste and flavor, 9 varieties with crisp, delicate and juicy flesh were initially screened, including Zaocuimi, Zaoqiuhong, Fucuimi, Yingbailu, Yueguang, Jingzao 28, Jingzao 60, Luzao 5 and Yulu. Three varieties of Jingzao 60, Jingzao 28 and Yueguang with good comprehensive fruit quality were selected by the comprehensive score of grey correlation degree. [Conclusion] Jingzao 60, Jingzao 28 and Yueguang can be promoted and cultivated as the main fresh jujube varieties in southern Xinjiang as they well adapted to the climate and site conditions and showed good yield and fruit quality.

Populus deltoides is one of the primary tree species for bioenergy production in temperate regions. In arid/semi-arid northern China, the scarcity of water and nitrogen significantly limits the productivity of poplar plantations. The identification of relevant molecular markers can promote the breeding of resource-efficient varieties. In this study, 188 genotypes of P. deltoides from six provenances served as experimental material. Genetic differentiation analysis, analysis of molecular variance (AMOVA), principal coordinate analysis (PCoA), unweighted pair group method with arithmetic mean (UPGMA) clustering, and genetic structure analysis were performed using selected simple sequence repeat (SSR) markers. Based on these analyses, the association analysis of water-use efficiency (WUE) and nitrogen-use efficiency (NUE) were conducted using general linear model (GLM) and mixed linear model (MLM) approaches. The results showed that 15 pairs of SSR primers successfully amplified across all 188 individuals, with an average of 7.33 alleles (Na) observed per primer pair. The polymorphism information content (PIC) ranged from 0.060 to 0.897, with an average of 0.544, indicating high genetic diversity in the selected markers. The average inbreeding coefficient intra-population (Fis), inbreeding coefficient inter-population (Fit), and inter-population genetic fraction coefficient (Fst) values were 0.005, 0.135, and 0.132, respectively, indicating high heterozygosity, substantial inbreeding within populations, and moderate genetic differentiation, with an average gene flow (Nm) of 1.964, suggesting substantial gene flow between populations. Additionally, molecular variance was primarily within individuals (84.12%). Genetic structure analysis revealed four subgroups, with some degree of genetic admixture among the provenances. In the GLM model, 11 markers were significantly associated with five traits (p < 0.05), with an average contribution rate of 15.82%. Notably, SSR132 and SSR143 were significantly associated with multiple traits (p < 0.05). The MLM model identified two markers (SSR47 and SSR85) significantly associated with ground diameter (p < 0.05) and one marker (SSR80) significantly associated with NUE (p < 0.05). This study identifies loci associated with WUE and NUE, laying a foundation for future genetic improvement and marker-assisted breeding strategies in poplar. [ABSTRACT FROM AUTHOR]

Simple Summary: Urbanization has been regarded as a major threat to fish diversity in urban waters. Xinglinwan Reservoir, a lentic brackish ecosystem with a distinct salinity gradient in southeastern China, is experiencing rapid urbanization, and there are no reports on fish diversity here. Environmental DNA metabarcoding (eDNA) has been applied to biodiversity assessments in aquatic ecosystems, but there has been limited work on fish diversity in lentic brackish ecosystems. We assessed the fish diversity and spatial distribution along a salinity gradient in Xinglinwan Reservoir, combining eDNA and the traditional survey method (TSM). This study provides realistic pictures of fish species assemblages in Xinglinwan Reservoir and tests the efficiency of eDNA for assessing fish diversity in lentic brackish ecosystems. Our results contribute to the conservation of fish resources in Xinglinwan Reservoir and advance the application of eDNA in lentic brackish ecosystems. With the decrease in fish diversity, the monitoring of fish has become a current research hotspot. Here, the fish diversity and spatial distribution along a salinity gradient (0.28‰–3.32‰) in Xinglinwan Reservoir, China, were investigated using eDNA and the TSM. With the combination of both methods, 12 species from 6 orders, 9 families, and 11 genera were observed. The invasive species Oreochromis niloticus had the highest relative abundance, accounting for 56.91% in the TSM and 89.80% in eDNA, respectively. eDNA detected 83.33% of the species detected using the TSM, and an additional six species (50.0% of the total species) were detected via only eDNA. Moreover, eDNA supplemented the unavailable abundance data from the TSM. The TSM revealed that the diversity and relative abundance of fish inhabiting seawater and brackish water increased with an increase in salinity, but this was not found using eDNA. Thus, our study highlights that Xinglinwan Reservoir has a low species richness and is suffering from the great harm of ecological invasion. Our findings also show that eDNA could be reliable for providing a comprehensive picture of fish, but discriminating the spatial heterogeneity of fish communities is a challenge for its widespread adoption in lentic brackish systems.

We prove the existence of invariant tori to the area-preserving maps defined on R 2 × T x ¯ = F (x , θ) , θ ¯ = θ + α (α ∈ R \ Q) , where F is related to a linear rotation, and the perturbation is ultra-differentiable in θ ∈ T , which is very closed to C ∞ regularity. Moreover, we assume that the frequency α is any irrational number without other arithmetic conditions and the smallness of the perturbation does not depend on α . Thus, both the difficulties from the ultra-differentiability of the perturbation and Liouvillean frequency will appear in this work. The proof of the main result is based on the Kolmogorov-Arnold-Moser (KAM) scheme about the area-preserving maps with some new techniques. [ABSTRACT FROM AUTHOR]

Background: Although peritoneal dialysis (PD) is an efficient therapy for renal replacement, the long-term survival rate of patients undergoing PD remains low. The platelet-to-albumin ratio (PAR), recently identified as a parameter of inflammatory and nutritional status, is associated with an adverse prognosis for various diseases. However, the association between the serum PAR and prognosis of patients undergoing PD is poorly understood. This study aimed to evaluate whether the PAR is a reliable predictor of cardiovascular disease (CVD) and all-cause mortality in patients undergoing PD. Methods: This multicenter cohort study enrolled patients undergoing PD from January 1, 2009, to September 30, 2018. The patients were divided into four groups according to the quartiles of their baseline PAR. The primary endpoint was all-cause and CVD-related mortality. Cox proportional hazard models were used to determine the association between the PAR and all-cause or CVD-related mortality. The receiver operating characteristic (ROC) curve was utilized to compare the performance among PAR and other inflammatory indicators. C-statistic, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were applied to examine the incremental prognostic value of PAR compared with baseline model for predicting all-cause and CVD mortality. Results: A total of 2825 patients were included. During the follow-up period of 47.5 ± 28.3 months, 747 (26.4%) mortality cases were observed, of which 415 (55.6%) were CVD-related. Compared with the Q1 (PAR < 4.43), placement in Q4 (PAR > 7.27) was associated with an increased risk of all-cause mortality and CVD mortality (p < 0.001). The adjusted restricted cubic spline analysis indicated that the relationship of the PAR with all-cause and cardiovascular mortality was linear (p for nonlinearity = 0.289 and 0.422, respectively). No positive correlations were shown in the interaction tests. PAR exhibited superior predictive value for mortality compared to other inflammatory indicators, with a respective AUC value of 0.611 (P < 0.001) for all-cause mortality and 0.609 (P < 0.001) for cardiovascular mortality. According to the C-statistic, continuous NRI and IDI, the addition of PAR to the baseline model yielded a moderate but significant improvement in outcome prediction. Conclusions: The PAR is an independent prognostic factor associated with all-cause and cardiovascular mortality in patients undergoing PD. [ABSTRACT FROM AUTHOR]

Triple‐negative breast cancer (TNBC), a highly aggressive form of breast cancer, currently lacks targeted therapies and is associated with high recurrence rates in medical practice. In this study, the effectiveness of a specially developed magnetic nanodrug, namely doxorubicin (DOX)‐loaded Fe3O4 vortex magnetic nanoannulars coated with a cancer cell membrane (DOX‐VMAs@CM), against cancer under a varying low‐frequency magnetic field (MF), is investigated. This advanced nanodrug can specifically target and accumulate in tumors. Additionally, it considerably improves tumor suppression compared with that of DOX chemotherapy alone, indicating the possibility of homologous targeting of the cancer cell membrane and the vibrating effect of the MF. The DOX‐VMAs@CM nanoparticles (NPs) exhibit exceptional safety characteristics because of their ability to specifically target tumors. The results of RNA sequencing suggest that the potential mechanisms may involve cellular respiration, cell cycle, and ferroptosis regulation. Altogether, chemotherapy is successfully optimized by implementing a delivery system and MF intervention, and the developed DOX‐VMAs@CM NPs hold significant potential for use in the clinical treatment of TNBC.

Radiation liver injury is a common complication of hepatocellular carcinoma radiotherapy. It is mainly caused by irreversible damage to the DNA of hepatocellular cells directly by radiation, which seriously interferes with metabolism and causes cell death. AdipoRon can maintain lipid metabolism and stabilize blood sugar by activating adiponectin receptor 1 (AdipoR1). However, the role of AdipoRon/AdipoR1 in the regulation of ionizing radiation (IR)-induced mitochondrial damage remains unclear. In this study, we aimed to elucidate the roles of AdipoRon/AdipoR1 in IR-induced mitochondrial damage in normal hepatocyte cells. We found that AdipoRon treatment rescued IR-induced liver damage in mice and mitochondrial damage in normal hepatocytes in vivo and in vitro. AdipoR1 deficiency exacerbated IR-induced oxidative stress, mitochondrial dynamics, and biogenesis disorder. Mechanistically, the absence of AdipoR1 inhibits the activity of adenosine monophosphate-activated protein kinase α (AMPKα), subsequently leading to disrupted mitochondrial dynamics by decreasing mitofusin (MFN) and increasing dynamin-related protein 1 (DRP1) protein expression. It also controls mitochondrial biogenesis by suppressing the peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC1α) and transcription factor A (TFAM) signaling pathway, ultimately resulting in impaired mitochondrial function. To sum up, AdipoRon/AdipoR1 maintain mitochondrial function by regulating mitochondrial dynamics and biogenesis through the AdipoR1-AMPKα signaling pathway. This study reveals the significant role of AdipoR1 in regulating IR-induced mitochondrial damage in hepatocytes and offers a novel approach to protecting against damage caused by IR.

As one of China's important environmental and economic policies, the environmental protection tax (EPT) is important in promoting economic and social green transformation. In this study, the green total factor productivity (GTFP) of 283 prefecture-level cities in China from 2013 to 2022 was calculated using a Super Slack-Based Model (Super-SBM) and the Malmquist-Luenberger (ML) index, which includes undesirable outputs. Moreover, the implementation effect of environmental tax on promoting urban green transformation is identified through the difference-in-differences (DID) model. This study revealed that (1) an EPT can significantly increase the GTFP of a city and promote its green transformation. (2) Industrial structure optimization and technological innovation are important mechanisms through which EPT drives urban green transformation. (3) The implementation effect of EPT in promoting urban green transformation presents significant policy differences across geographic locations, whether cities are key environmental protection cities or types of resource-based cities. EPT can significantly promote the green transformation of local cities, which in turn can positively affect the green transformation of neighboring cities. Based on this study's conclusions, suggestions are put forward to improve the EPT system to promote urban green transformation. [ABSTRACT FROM AUTHOR]

Lithium‐ion batteries (LIBs) suffer from energy loss and safety hazards under high‐rate conditions, because of the sluggish electrochemical kinetics and unstable interfacial passivation. Herein, a PC‐based electrolyte using weakly solvated solvent ethyl trifluoroacetate is developed to improve interfacial kinetics and stability in LIBs. A microsolvating competition is revealed in the bulk electrolyte, forming a loose Li+ coordination configuration with benign Li+ affinity and high ionic conductivity. Furthermore, an inorganic‐rich interphase is constructed on a graphite anode, affording smooth Li+ desolvation and reliable passivation. Consequently, the NCM622/graphite cell in PC‐based electrolyte shows improved cycling stability (82.2% after 200 cycles) and rate capability (83% at 4C compared to 0.1C) at a high‐voltage of 4.5 V, much better than those of EC‐based electrolyte (76.2% after 200 cycles and 74% at 4C). Additionally, the PC‐based electrolyte affords reversible operation at –40 °C while the EC‐based electrolyte fails at –40 °C. This work highlights the potential of solvation structure engineering for low‐energy‐barrier electrolyte. [ABSTRACT FROM AUTHOR]

Submarine groundwater discharge (SGD) plays a crucial role in nutrient budgets of coastal systems, encompassing both submarine fresh groundwater discharge (SFGD) and recirculated saline groundwater discharge (RSGD). Despite its significance, the specific importance of these components in mariculture bays has not been thoroughly assessed. Here, utilizing Ra isotopes and water‐salt mass balance model, we show that SFGD flux (1.1 ± 0.4 cm d−1) represented only 17% of the SGD in the Zhenzhu Bay, a typical mariculture bay along the South China Sea. Interestingly, the nutrient contribution from SFGD surpassed that from RSGD, accounting for 82% of the dissolved inorganic nitrogen (DIN) flux within the SGD. Analysis of the monthly satellite Chlorophyll‐a (Chl‐a) data confirmed that the decline in phytoplankton biomass can be linked to the limited dissolved silicate (DSi) transported by SFGD. Additionally, the elevated nitrogen to phosphorus ratio (241:1) and reduced silicon to nitrogen ratio (0.5:1) in SFGD compared to the Redfield ratio suggested that SFGD characterized by nitrogen excess and silica deficient, which likely played a role in transitioning from biogenic element constraints in coastal water. This shift may impact the proportions and functionality of the phytoplankton community, potentially mitigating water eutrophication. These findings underscore the significant influence of SGD on nutrient dynamics and the ecological environment in the Zhenzhu Bay. Plain Language Summary: Submarine groundwater discharge (SGD) is a significant process in coastal regions worldwide. Nutrients by SGD can disrupt the ecological balance of bays, altering nutrient structures and primary productivity in coastal ecosystems. However, this nutrient influx may exacerbate issues such as eutrophication and hypoxia in these waters. Although SGD acts as a significant nutrient source in the Zhenzhu Bay, there remains a scarcity of knowledge in distinguishing between submarine fresh groundwater discharge (SFGD) and recirculated saline groundwater discharge (RSGD), potentially resulting in overestimations of SGD. By utilizing Ra isotopes and a water‐salt mass balance model, we quantified the various components of SGD along with their nutrient fluxes. The study revealed that the persistent discharge of nitrogen‐contaminated fresh groundwater could eventually shift coastal waters from a nitrogen‐limited state to a phosphorus‐limited state. Moreover, the SFGD component under silicon‐limited conditions may restrict primary productivity particularly among freshwater diatom species. These findings contribute to enhancing our comprehension of how nutrients delivered by different SGD components impact marine ecosystems, but long‐term monitoring of SFGD and RSGD components is recommended to evaluate potential hazards and their influence on the ecological environment. Key Points: Nutrient fluxes from submarine fresh groundwater exceeded river by a factor of at least 3 timesSubmarine fresh groundwater discharge (SFGD) contributed more dissolved inorganic nitrogen than recirculated saline groundwater dischargeThe decline in phytoplankton biomass can be linked to the scarcity dissolved silicates in SFGD [ABSTRACT FROM AUTHOR]

The adaptability of marine organisms to changes in salinity has been a significant research area under global climate change. However, the underlying mechanisms of this adaptability remain a debated subject. We hypothesize that neglecting salinity fluctuation properties is a key contributing factor to the controversy. The ciliate Euplotes vannus was used as the model organism, with two salinity fluctuation period sets: acute (24 h) and chronic (336 h). We examined its population growth dynamics and energy metabolism parameters following exposure to salinity levels from 15‰ to 50‰. The carrying capacity (K) decreased with increasing salinity under both acute and chronic stresses. The intrinsic growth rate (r) decreased with increasing salinity under acute stress. Under chronic stress, the r initially increased with stress intensity before decreasing when salinity exceeded 40‰. Overall, glycogen and lipid content decreased with stress increasing and were significantly higher in the acute stress set compared to the chronic one. Both hypotonic and hypertonic stresses enhanced the activities of metabolic enzymes. A trade-off between survival and reproduction was observed, prioritizing survival under acute stress. Under chronic stress, the weight on reproduction increased in significance. In conclusion, the tested ciliates adopted an r-strategy in response to salinity stress. The trade-off between reproduction and survival is a significant biological response mechanism varying with salinity fluctuation properties. [ABSTRACT FROM AUTHOR]

Due to the increasingly fierce competition in recent years, the e-retailers try to establish cooperation alliance. In this paper, we study a profit allocation problem in the multiple-channels order fulfillment system of an e-retailers cooperation alliance. The aim of the cooperation is to maximize the total profit of the alliance by sharing the orders and inventories of goods of all e-retailers, which also helps to increase the profit of each e-retailer. After cooperation, a Rule-utilitarianism core (RUC) profit allocation mechanism is designed to fairly allocate the total profit of the alliance. RUC mechanism is compared with well know Shapley allocation and Egalitarian core allocation. The effectiveness of the RUC mechanism is verified by numeric experiments. The results show that the cooperation can bring more profits for all e-retailers and the RUC mechanism can insure the stability of the alliance on the basis of the contribution measure of each e-retailer to the alliance.

Background: LncRNAs perform a crucial impact on microglia's activation in Parkinson's disease (PD). Here, our purpose was to probe the function and involved mechanism of lncRNA SOX21-AS1 on microglial activation in PD. Methods: Mice were treated with MPTP, and BV2 cells were treated with LPS/ATP to build PD animal and cell models. Genes' expression was measured using RT-qPCR, immunoblotting, and IHC stain. ELISA was applied for testing inflammatory factors' levels. Cell viability and apoptosis were tested using kits. RIP and RNA pull-down assay were utilized for monitoring the bond of SOX21-AS1 to EZH2, and ChIP was applied for affirming the bond between EZH2 and SOCS3's promoter. Results: The expression of SOX21-AS1 and SOCS3 was abnormal in PD cell and animal models. Inhibition of SOX21-AS1 repressed LPS/ATP-induced activation in BV2 cells and nerve damage caused by activated BV2 cells, alleviating the pathological features of PD mice. Further studies found that SOX21-AS1 epigenetically inhibited SOCS3 by recruiting EZH2 to SOCS3 promoter. SOX21-AS1 overexpression partially offset the repressive impact of SOCS3 enhancement on BV2 cell activation and the protective effect on nerve cells. Conclusion: SOX21-AS1 enhances LPS/ATP-induced activation of BV2 cells and nerve damage caused by activated BV2 cells though recruiting EZH2 to SOCS3's promoter, thereby alleviating PD progression. Our research supplies new potential target for curing PD. [ABSTRACT FROM AUTHOR]

Introduction: The pathogenesis of psoriasis is complex. Previous bioinformatics studies have found differential expression of HIF-1α and miR-199 in psoriasis, but the correlation between miR-199a and HIF-1α and the severity of psoriasis is still unclear. This study found differential expression of HIF-1α and miR-199a levels in the skin lesions of patients with different degrees of psoriasis. HIF-1α mRNA and miR-199a are PASI influencing factors, and the levels of HIF-1 α and miR-199a in the skin lesions can serve as potential indicators for evaluating the severity index of psoriasis. Aim: To examine the relationships between the levels of HIF-1α and miR-199a and psoriasis severity. Material and methods: Sixty-five patients with psoriasis vulgaris treated from January 2023 to May 2024 were divided into a mild group (n = 16), a moderate group (n = 23), and a severe group (n = 26) according to the lesion area and severity index (PASI) score, and 40 healthy people were included in the control group (group A). The expression of HIF-1a and miR-199a in psoriatic lesions and normal skin tissues was detected by fluorescence quantitative PCR. Results: The level of miR-199a in lesions in the observation group (group B) was lower than that in group A, but the level of HIF-1αmRNA in group B was greater than that in group A. The level of miR-199a in moderate and severe psoriasis patients was lower than that in mild psoriasis patients, and that in severe psoriasis patients was lower than that in moderate psoriasis patients. HIF-1α mRNA in lesions was positively associated with the PASI in psoriasis patients, and the miR-199a level in lesions was positively associated with the PASI in psoriasis patients. Furthermore, taking the PASI as the dependent variable and HIF-1αmRNA and miR-199a with a linear relationship with the dependent variable as the independent variables, multiple stepwise regression analysis showed that HIF-1α mRNA and miR-199a influenced the PASI. Conclusions: HIF-1α and miR-199a are differentially expressed in the lesions of patients with different severities of psoriasis. The HIF-1α and miR-199a levels in lesions can be used as potential indices to evaluate the severity of psoriasis. [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. Tumor immune microenvironment (TIME), angiogenesis, epithelial-mesenchymal transformation (EMT), invasion, metastasis, metabolism, and drug resistance are the main factors affecting the development and treatment of tumors. MiRNAs play crucial roles in almost all major cellular biological processes. Studies have been carried out on miRNAs as biomarkers and therapeutic targets. Their dysregulation contributes to the progression and prognosis of HCC. This review aims to explore the molecular cascades and corresponding phenotypic changes caused by aberrant miRNA expression and their regulatory mechanisms, summarize and analyze novel biomarkers from somatic fluids (plasma/serum/urine), and highlight the latent capacity of miRNAs as therapeutic targets.

Objective: The purpose of this study was to investigate the epidemiological and genomic characteristics of Vibrio parahaemolyticus (V. parahaemolyticus) isolates from outbreaks in Huzhou, China. Methods: This study aims to analyze the epidemiological data on V. parahaemolyticus outbreaks reported in Huzhou from 2019 to 2023. A total of 70 V. parahaemolyticus outbreak isolates were collected. The antibiotic resistance, serotypes, molecular typing, and genomic characteristics of these isolates were analyzed. Results: Most outbreaks of V. parahaemolyticus infection occurred in the summer, and the majority of outbreaks occurred in restaurants and rural banquets. High resistance rates were observed for ampicillin (AMP, 24.29%), followed by tetracycline (TET, 15.71%) and trimethoprim-sulfamethoxazole (SXT, 15.71%). The newly emerged serotype O10:K4 became dominant from 2021 to 2023, with most isolates belonging to ST3. The resistance gene blaCARB was frequently detected among these isolates. The pulsed-field gel electrophoresis (PFGE) and whole-genome single-nucleotide polymorphisms (wgSNPs) effectively differentiated the nine outbreaks. Conclusion: The newly emerged serotype O10:K4 became dominant from 2021 to 2023, with most isolates being ST3. PFGE and WGS technologies provided reliable methods for typing and identifying V. parahaemolyticus for outbreaks. [ABSTRACT FROM AUTHOR]
