Local government debt (LGD), an important financing tool for local governments to achieve high-quality development, especially through the expansion of urban investment bonds led by local investment and financing platforms, has a significant impact on green development efficiency (GDE). This article starts from LGD, selects data from 30 provinces from 2010 to 2019, and uses a two-way fixed-effect model and mediation-effect model to empirically analyze the impact of LGD on GDE. The research results show that LGD has a significant inhibitory effect on GDE, and LGD can indirectly affect GDE through the degree of industrialization and the number of the urban population. This article suggests that the government should make even fuller use of LGD funds, optimize the use of relevant funds, standardize the operation of local government investment and financing platforms, reduce debt risks, promote industrial structure upgrading, promote urban population resettlement measures, and improve China's GDE.

Since the reform of the tax-sharing system in 1994, the regulation of the central government to local governments has relied on the mean of intergovernmental fiscal transfers (IFTs) to a certain extent. However, the existing literature has not yet explored the influence of fiscal decentralization (FD) on energy consumption in the presence of IFTs. Thus, this study empirically examines the influences of FD and IFTs on energy consumption by using panel data for 30 Chinese provinces during the period of 1998–2019. Results indicate that FD and IFTs have positive effects on energy consumption. Moreover, the positive influence of FD on energy consumption is strengthened by the improvement in IFTs. In addition, FD and IFTs affect energy consumption through industrial structure upgrading. In terms of policy implications, this study suggests that China may further reduce energy consumption by appropriately reducing the degree of FD, optimizing the intergovernmental fiscal transfer system, and promoting the upgrading of industrial structure.

Objective: To evaluate the effect of preventive interventions for lateral ankle sprain in the general population. Data sources: A search of PubMed, EMBASE, Cochrane CENTRAL, Medline, CINAHL, and ClinicalTrials.gov was conducted up to August 2022. Review methods: Randomized controlled trials and prospective cohort studies that evaluated any interventions for preventing lateral ankle sprain were included. Two reviewers independently conducted the search, screening, and data extraction. The methodological quality of each study was assessed using the revised Cochrane risk-of-bias tool for randomized trials or using the Cochrane Risk Of Bias In Non-Randomized Studies tool for prospective cohort studies. Results: Seventeen studies met the inclusion criteria. Proprioceptive training exhibited better effects on preventing future lateral ankle sprain compared with the control group (risk ratio = 0.59, p < 0.001), and a stronger preventive effect was observed in participants with a history of lateral ankle sprain in the subgroup analysis (risk ratio = 0.49, p = 0.02). Compared with no bracing, ankle bracing had no significant better effect in preventing lateral ankle sprain (risk ratio = 0.43, p = 0.05). Proprioceptive training and ankle bracing had similar preventive effects (risk ratio = 0.98, p = 0.97). Limited evidence hindered the synthesis of data on pain, swelling, costs, and time loss. Conclusion: Proprioceptive training is recommended for preventing lateral ankle sprain, especially for people with a history of lateral ankle sprain. Bracing seems to have an ambiguous preventive effect and requires more further investigation. [ABSTRACT FROM AUTHOR]

With regard to lending to small and micro enterprises (SMEs), the cost of traditional finance is mainly marginal. By contrast, the cost of Internet finance is mainly fixed, and the average cost of Internet finance is largely reduced. From the perspective of cost structure and size changes, we build dynamic equilibrium models. We prove that the transition from traditional to Internet finance will increase the number of SMEs obtaining loans and the aggregate output. We also conduct a quantitative analysis with the result revealing that Internet finance will increase China's credit-access SMEs by 619.91% and aggregate output by 2.72%. [ABSTRACT FROM AUTHOR]

Osteosarcoma, recognized for its aggressiveness and resistance to chemotherapy, notably doxorubicin, poses significant treatment challenges. This comprehensive study investigated the CXCR4-CARM1-YAP signaling axis and its pivotal function in controlling aerobic glycolysis, which plays a crucial role in doxorubicin resistance. Detailed analysis of Dox-resistant 143b/MG63-DoxR cells has uncovered the overexpression of CXCR4. Utilizing a combination of molecular biology techniques including gene silencing, aerobic glycolysis assays such as Seahorse experiments, RNA sequencing, and immunofluorescence staining. The study provides insight into the mechanistic pathways involved. Results demonstrated that disrupting CXCR4 expression sensitizes cells to doxorubicin-induced apoptosis and alters glycolytic activity. Further RNA sequencing revealed that CARM1 modulated this effect through its influence on glycolysis, with immunofluorescence of clinical samples confirming the overexpression of CXCR4 and CARM1 in drug-resistant tumors. Chromatin immunoprecipitation studies further highlighted the role of CARM1, showing it to be regulated by methylation at the H3R17 site, which in turn affected YAP expression. Crucially, in vivo experiments illustrated that CARM1 overexpression could counteract the tumor growth suppression that resulted from CXCR4 inhibition. These insights revealed the intricate mechanisms at play in osteosarcoma resistance to doxorubicin and pointed toward potential new therapeutic strategies that could target this metabolic and signaling network to overcome drug resistance and improve patient outcomes., (© 2024 The Author(s).

Osteoarthritis (OA) is marked by cartilage deterioration, subchondral bone changes, and an inflammatory microenvironment. The study introduces the Microneedle-Delivered Polydopamine-Exosome (PDA@Exo MN), a therapeutic that not only preserves cartilage and promotes bone regeneration but also improves localized drug delivery through enhanced penetration capabilities. PDA@Exo MN shows strong reactive oxygen species (ROS) scavenging abilities and high biocompatibility, fostering osteogenesis and balancing anabolic and catabolic processes in cartilage. It directs macrophage polarization from M0 to the anti-inflammatory M2 phenotype. RNA sequencing of treated chondrocytes demonstrates restored cellular function and activated antioxidant responses, with modulated inflammatory pathways. The PI3K-AKT-mTOR pathway's activation, essential for PDA@Exo's effects, is confirmed via bioinformatics and Western blot. In vivo assessments robustly validate that PDA@Exo MN prevents cartilage degradation and OA progression, supported by histological assessments and micro-CT analysis, highlighting its disease-modifying impact. The excellent biocompatibility of PDA@Exo MN, verified through histological (H&E) and blood tests showing no organ damage, underscores its safety and efficacy for OA therapy, making it a novel and multifunctional nanomedical approach in orthopedics, characterized by organ-friendliness and biosecurity., (© 2024 The Author(s).

Background: Corona Virus Disease 2019 (COVID-19) and Osteoarthritis (OA) are diseases that seriously affect the physical and mental health and life quality of patients, particularly elderly patients. However, the association between COVID-19 and osteoarthritis at the genetic level has not been investigated. This study is intended to analyze the pathogenesis shared by OA and COVID-19 and to identify drugs that could be used to treat SARS-CoV-2-infected OA patients., Methods: The four datasets of OA and COVID-19 (GSE114007, GSE55235, GSE147507, and GSE17111) used for the analysis in this paper were obtained from the GEO database. Common genes of OA and COVID-19 were identified through Weighted Gene Co-Expression Network Analysis (WGCNA) and differential gene expression analysis. The least absolute shrinkage and selection operator (LASSO) algorithm was used to screen key genes, which were analyzed for expression patterns by single-cell analysis. Finally, drug prediction and molecular docking were carried out using the Drug Signatures Database (DSigDB) and AutoDockTools., Results: Firstly, WGCNA identified a total of 26 genes common between OA and COVID-19, and functional analysis of the common genes revealed the common pathological processes and molecular changes between OA and COVID-19 are mainly related to immune dysfunction. In addition, we screened 3 key genes, DDIT3, MAFF, and PNRC1, and uncovered that key genes are possibly involved in the pathogenesis of OA and COVID-19 through high expression in neutrophils. Finally, we established a regulatory network of common genes between OA and COVID-19, and the free energy of binding estimation was used to identify suitable medicines for the treatment of OA patients infected with SARS-CoV-2., Conclusion: In the present study, we succeeded in identifying 3 key genes, DDIT3, MAFF, and PNRC1, which are possibly involved in the development of both OA and COVID-19 and have high diagnostic value for OA and COVID-19. In addition, niclosamide, ciclopirox, and ticlopidine were found to be potentially useful for the treatment of OA patients infected with SARS-CoV-2., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Zhang, Duan, Guan, Xu, Fu and Li.)
