Grid company archive data has the characteristics of multimodality, mass and diversity, covering structured, semi-structured and unstructured data. These data have the problems of low utilization efficiency and serious information silo effect under the traditional management mode. In order to solve the above problems, this paper proposes a multimodal archive data intelligent utilization technology framework based on artificial intelligence deep learning. Firstly, the convolutional neural network is used to extract features from the image data in the archive to realize image classification and target detection; secondly, the BERT model and the Transformer structure are used to process the archive text data for semantic extraction and text classification; finally, the multimodal Transformer model is used to realize the joint modeling and information sharing of the cross-modal data to solve the problem of isolated and correlation analysis between the data. isolation and correlation analysis. This study provides technical support and application demonstration for the intelligent management and intelligent transformation of power grid company archive data.

Under the dual pressures of global warming and accelerated urbanization, urban green spaces (UGS) serve as crucial yet paradoxical elements, alleviating urban heat island (UHI) effects while emitting biogenic volatile organic compounds (BVOCs) that exacerbate air pollution;however, their spatial trade-offs remain underexplored. This study bridges this gap by developing an Urban Heat Mitigation Index (HMI) and a BVOC flux accounting framework integrating remote sensing and field observations. The results showed that (1) the cooling effect exhibits significant spatial heterogeneity, with continuous green networks around West Lake and along the Qiantang River forming efficient cooling corridors (HMI > 0.75), while fragmented green spaces in northeastern areas show weaker cooling effects (HMI < 0.35);(2) BVOC emission intensity displays a "high suburbs-low centers" pattern, with suburban areas emitting 1.9-2.3 times more BVOCs than urban centers, while BVOC-induced PM2.5 (0.02-0.05 mu g m(-3)) and O-3 (12-33 mu g m(-3)) concentrations in city centers still pose significant health risks;(3) spatial analysis reveals a weak positive correlation between HMI and BVOC emissions (Moran's I = 0.096, p < 0.05), with four distinct coupling patterns identified: "high cooling-low emissions" (17.5% of area), "low cooling-high emissions" (1.1%), "high cooling-high emissions" (18.7%), and "low cooling-low emissions" (3.9%). This study provides quantitative evidence for optimizing UGS layouts to balance ecological benefits and environmental risks, emphasizing the importance of vegetation screening and spatial allocation in sustainable urban planning.

Bronchial asthma (asthma) is a chronic inflammatory disease of the airways that remains an unresolved problem. Reportedly M2 macrophages and exosomes play a role in inflammation, including asthma. We investigated the roles of M2 macrophage-derived exosomes (M2-Exos) effect in asthmatic progression by using ovalbumin (OVA) induced asthmatic mice model. M2-Exos significantly ameliorated the pulmonary inflammatory response and airway hyperresponsiveness in asthmatic mice and suppressed aberrant proliferation and transient receptor potential polycystic protein 2(TRPP2) expression in LPS-stimulated primary airway smooth muscle cells (ASMCs). Then, we found that miR-186-5p of M2-Exos could target TRPP2 through online database analysis. However, miR-186-5p downregulation by miR-186-5p inhibitors decreased the protective effect of M2-Exos in asthmatic mouse and cellular models. miR-186-5p was identified and selectively combined with the polycystin-2 gene encoding TRPP2 protein, inhibited TRPP2 protein production, and downregulated TRPP2 expression. A reduction in the number of TRPP2 calcium (Ca) channels formed on the cell membrane leads to a decreased intracellular Ca2+ concentration ([Ca2+] i), causing reduced ASMC contraction and proliferation, thereby improving airway hyperresponsiveness and airway remodeling in asthma. Collectively, we conclude that M2 exosomal miR-186-5p to alleviate asthma progression and airway hyperresponsiveness though downregulating TRPP2 expression. These results may offer a novel insight to the treatment and drug delivery of asthma.

The production of multi-carbon compounds through CO2 photoreduction (CO2PR) holds great promise but faces challenges due to high kinetic barriers and the sluggish process of C-C coupling. Overcoming these obstacles requires fine engineering of active sites. In this study, Ni active sites are engineered through the synergistic effect of metal-oxo cluster (Mo7O246-) and hydroxyl vacancy (V-OH). In contrast to the Ni sites unmodified with Mo7O246- and V-OH, which are unable to produce multi-carbon products, the constructed electron-enriched Ni active sites exhibit an impressive selectivity of up to 43.02% and a high yield rate of 246.70 mu mol g(-1) h(-1) for C2H6, which represent one of the best results for CO2PR to C2H6. Through a comprehensive investigation involving operando experiments and theoretical simulations, hydroxyl vacancy and the formed Mo & horbar;O & horbar;Ni bonds is demonstrated due to the filling of hydroxyl vacancies with oxygen atoms from Mo7O246- synergistically constructed electron-rich Ni sites. Such Ni sites efficiently catalyze CO2 conversion to C2H6 by enhancing the adsorption of *CO, promoting subsequent hydrogenation, and enabling low energy barriers for CO2 hydrogenation to *OCOH and the coupling of *CH3 intermediates. This study provides deeper insights into the photocatalytic process, highlighting the significance of tailored active sites for efficient CO2 conversion.

Objective: Previous studies have reported that depression and depressive symptom are associated with diabetes incident. However, the association between long-term depressive symptom patterns and risk of diabetes remains unknown. The aim of present study was to evaluate the association between depressive symptom trajectories and risk of ***: We used data of 8806 participants (>= 45 years old) from the China Health and Retirement Longitudinal Study (CHARLS). Trajectories of depressive symptom were identified by latent mixture modeling. Multivariable logistic regression model was used to examine the association of depressive symptom trajectories with ***: Five depressive symptom trajectories were identified, characterizing by maintaining a low CES-D scores throughout the follow-up (low-stable;3227 participants [36.65%]);maintaining a moderate CES-D scores throughout the follow-up (moderate-stable;3402 participants [38.63%]);moderate starting CES-D scores then increasing scores (moderate-increasing;681 participants [7.73%%]);high starting CES-D scores but then decreasing scores (high-decreasing;1061 participants [12.05%]);and maintained high CES-D scores throughout the follow-up (high-stable;435 participants [4.94%]). During 2015 to 2018 (Wave 3 to Wave 4), a total of 312 respondents experienced diabetes. Compared with participants in the low-stable depressive symptom trajectory, those following a high-decreasing (ORs = 2.04;95%CIs 1.48-2.98) and high-stable depressive symptom tra-jectories (ORs = 3.26;95%CIs 2.06-5.16) were at substantially higher risk of developing ***: Individuals with high-decreasing and high-stable depressive symptom trajectories over time were associated with increased risk of incident diabetes. Long-term depressive symptom may be a strong predictor of having diabetes.

Mucosal contact of the tip of colonoscopy causes red-out views, and more pressure may result in perforation. There is still a lack of quantitative analysis methods for red-out views. We aimed to develop an artificial intelligence (AI)-based system to assess red-out views during intubation in colonoscopy. Altogether, 479 colonoscopies performed by 34 colonoscopists were analysed using the proposed semi-supervised AI-based system. We compared the AI-based red-out avoiding scores among novice, intermediate, and experienced colonoscopists. The mean AI-based red-out avoiding scores were compared among groups stratified by expert-rated direct observation of procedure or skill (DOPS)-based tip control assessment results. Both the percentage of actual red-out views (p < 0.001) and AI-based red-out avoiding scores (p < 0.001) were significantly different among the novice, intermediate, and experienced groups. Colonoscopists who scored better on the DOPS-based tip control assessment also performed better on the AI-based red-out avoiding skill assessment. AI-based red-out avoiding score was negatively correlated with actual caecal intubation time and actual red-out percentage. Feedback of red-out avoiding score may help remind endoscopists to perform colonoscopy in an effective and safe manner. This system can be used as an auxiliary tool for colonoscopy training.

Chlorophylls in the skin contribute to grape (Vitis vinifera) berry color and quality. Degradation of chlorophyll occurs during berry development in grape, but less is known about the molecular mechanisms of this process. Here, we characterized an ethylene response factor, VvERF17, as a putative regulator of chlorophyll degradation in grape berry. VvERF17 expression was strongly correlates with development-induced and ETH-triggered chlorophyll degradation. Transient overexpression of VvERF17 in tobacco leaves, tomato fruits, and grape leaves led to color break and chlorophyll degradation, which were resulted from the upregulated expression of chlorophyll catabolic genes (CCGs), including Chlorophyll-b-reductase (NOL), pheophytinase (PPH), pheophorbide a oxygenase (PAO), and red Chlorophyll catabolite reductase (RCCR). Inversely, silencing of VvERF17 in grape leaves partially suppressed the expression of CCGs' expression. Major CCGs' expression was closely related to chlorophyll degradation and VvERF17 expression. It was further demonstrated that VvERF17 could activate the expression of major CCGs by directly binding to the ERF binding sites in their promoters. We conclude that VvERF17 mediates chlorophyll degradation by transcriptional activation of NOL, PPH, PAO, and RCCR. These findings elucidate the regulation mechanisms of chlorophyll degradation in grape and enrich our understanding of grape berry color formation.
