AIM:To investigate the mechanism of flavonoid extract from Dracocephalum rupestre hance(DRHF)in the treatment of gouty arthritis through network pharmacology,molecular docking and animal experiment.METHODS:Literature re-trieval was used to explore the main active chemi-cal components and targets of DRHF.Gouty arthri-tis disease targets were obtained using Gene Cards and OMIM databases,and drug-disease intersect-ing targets were obtained using Wayne online tools.protein-protein interactions(PPI)and other related network diagrams were constructed using Cytoscape software.GO and KEGG enrichment analyses were performed on the shared intersect-ing targets using Metascape database.A rat model of gouty arthritis was established by Coderre meth-od;the swelling degree of ankle joint,gait behav-iour scores of rats were observed,and hematoxylin-eosin(HE)staining was performed.ELISA and real-time PCR were used to detect the key targets pre-dicted by the network pharmacology,and the ef-fects of DRHF on the molecular mechanism and key targets of gouty arthritis were observed.RESULTS:A total of 7 active compounds and 129 candidate targets for the treatment of GA were obtained,in-cluding IL-6,IL-1β,RELA,TNF,PPARG,etc.and the KEGG enrichment results suggested that DRHF may be involved in PI3K-Akt,TNF,IL-17 and other signal transduction pathways.Animal results:HE staining showed that the thickening of synovial tissue was not obvious in each administered group,and syno-vial cell proliferation and inflammatory cell infiltra-tion were significantly improved;compared with the normal group,the serum levels of TNF,IL-6,and IL-1β in the model group were significantly higher(P＜0.05),and the mRNA of PPARG,IL-6,and RELA in the synovial tissues were significantly high-er;compared with the model group,the levels of TNF,IL-6,and IL-1β were significantly lower(P＜0.05)in the low group of DRHF(0.45 g/kg)and high group of DRHF(0.9 g/kg),TNF,IL-6,IL-1β lev-els were significantly reduced(P＜0.05);PPARG,IL-6,RELA mRNA in synovial tissue were significantly reduced.CONCLUSION:DRHF inhibits IL-17/PI-3K/TNF signaling pathway by down-regulating the ex-pression of IL-6,PPARG and RELA mRNA,decreas-ing the levels of IL-6,IL-1β and TNF,and then treat-ing gouty arthritis.

Objective To evaluate the overall implementation of the WS 76-2020 standard in Anhui Province, China and identify and analyze the factors affecting the implementation of the standard, and to provide a basis for the effective implementation and revision of WS 76-2020. Methods According to the requirements of the Notice of the Department of Regulations in National Health Commission on the 2024 assessment of implementation of mandatory standards, an evaluation of radiological health standards was organized and conducted in Anhui Province. The evaluation involved the three dimensions of standard implementation status, technical content of the standards, and effectiveness of standard implementation, with subsequent data analysis. Results The total evaluation score for WS 76-2020 was 87.83 points, indicating that the standard effectively guided the quality control testing of medical X-ray diagnostic equipment. However, stability testing was either underutilized or not performed in practice. The qualified rate of X-ray diagnostic equipment in the province was 94.26%, with equipment performance issues identified as the leading contributor to non-qualified instances. Expert discussions highlighted recommendations particularly concerning the operability, applicability, and scientific rigor of the standard. Conclusion It is recommended to strengthen the dissemination and training for the standard, promote medical institutions to voluntarily conduct stability testing, provide supplementary clarifications or revisions for problematic clauses, and standardize quality control testing techniques for radiological diagnostic equipment.

BACKGROUND:There are still great controversies in the etiology,clinical manifestations,diagnosis and treatment of pigmented villonodular synovitis.Bibliometric and visualization studies on pigmented villonodular synovitis can clarify the research development context and point out the direction for future research.OBJECTIVE:To analyze the global research status,hotspot,and trend of pigmented villonodular synovitis.METHODS:All publications related to pigmented villonodular synovitis from 1995 to 2023 were retrieved from Web of Science and CNKI.Citespace and bibliometrics were used to analyze the clustering,co-occurrence,and emergent words of all articles.The Web of Science database adopts subject headings plus free words for retrieval,while the CNKI database retrieves through subject headings.Finally,986 English articles and 599 Chinese articles were included.RESULTS AND CONCLUSION:(1)The United States has an absolute leading position in research in this field,ranking first in the number of published papers,H index,and cited times.China ranks the 4th in the total volume of published articles and 12th in the H index.The quality of published articles and international cooperation still need to be improved.(2)Cluster analysis of pigmented villonodular synovitis studies showed that the top five clusters were radiotherapy,soft tissue sarcoma,rheumatoid arthritis,magnetic resonance imaging,and diagnosis.(3)The key words that continued to emerge until 2023 were colony-stimulating factor 1,giant cell tumor of tendon sheath,case report,chromosome translocation,radiotherapy,expression,and kinase.(4)Based on keyword analysis and co-citation analysis,it is found that the research on the clinical characteristics of pigmented villonodular synovitis,the development of new colony-stimulating factor 1 inhibitors,and the application of colony-stimulating factor 1 inhibitors in the treatment process are current research hotspots.(5)Combining thematic evolution with the analysis of current research hotspots,based on clarifying the etiology,pathogenesis,and clinical characteristics of pigmented villonodular synovitis,improving the diagnostic accuracy of pigmented villonodular synovitis,enhancing the precision of treatment,and reducing the recurrence rate after treatment will be key issues that require focus in the future.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

BACKGROUND:Chlorfenapyr is used to kill insects that are resistant to organophosphorus insecticides.Chlorfenapyr poisoning has a high mortality rate and is difficult to treat.This article aims to review the mechanisms,clinical presentations,and treatment strategies for chlorfenapyr poisoning. DATA RESOURCES:We conducted a review of the literature using PubMed,Web of Science,and SpringerLink from their beginnings to the end of October 2023.The inclusion criteria were systematic reviews,clinical guidelines,retrospective studies,and case reports on chlorfenapyr poisoning that focused on its mechanisms,clinical presentations,and treatment strategies.The references in the included studies were also examined to identify additional sources. RESULTS:We included 57 studies in this review.Chlorfenapyr can be degraded into tralopyril,which is more toxic and reduces energy production by inhibiting the conversion of adenosine diphosphate to adenosine triphosphate.High fever and altered mental status are characteristic clinical presentations of chlorfenapyr poisoning.Once it occurs,respiratory failure occurs immediately,ultimately leading to cardiac arrest and death.Chlorfenapyr poisoning is difficult to treat,and there is no specific antidote. CONCLUSION:Chlorfenapyr is a new pyrrole pesticide.Although it has been identified as a moderately toxic pesticide by the World Health Organization(WHO),the mortality rate of poisoned patients is extremely high.There is no specific antidote for chlorfenapyr poisoning.Therefore,based on the literature review,future efforts to explore rapid and effective detoxification methods,reconstitute intracellular oxidative phosphorylation couplings,identify early biomarkers of chlorfenapyr poisoning,and block the conversion of chlorfenapyr to tralopyril may be helpful for emergency physicians in the diagnosis and treatment of this disease.
