Alzheimer's disease (AD) is a neurodegenerative disease with clinical hallmarks of progressive cognitive impairment. Synergistic effects of the Aβ-Tau cascade reaction are tightly implicated in AD pathology, and microglial NLRP3 inflammasome activation drives neuronal tauopathy. However, the underlying mechanism of how Aβ mediates NLRP3 inflammasome remains unclear. Herein, we determined that oligomeric Aβ (o-Aβ) bound to microglial Kv2.1 and promoted Kv2.1-dependent potassium efflux to activate NLRP3 inflammasome resulting in neuronal tauopathy by using Kv2.1 inhibitor drofenine (Dfe) as a probe. The underlying mechanism has been intensively investigated by assays with Kv2.1 knockdown in vitro (si-Kv2.1) and in vivo (AAV-ePHP-si-Kv2.1). Dfe deprived o-Aβ of its capability to promote microglial NLRP3 inflammasome activation and neuronal Tau hyperphosphorylation by inhibiting the Kv2.1/JNK/NF-κB pathway while improving the cognitive impairment of 5×FAD-AD model mice. Our results have highly addressed that the Kv2.1 channel is required for o-Aβ-driven microglial NLRP3 inflammasome activation and neuronal tauopathy in AD model mice and highlighted that Dfe as a Kv2.1 inhibitor shows potential in the treatment of AD.

Objective:To explore the expression of YARS1, the subform of protein-based tRNA synthase ( YARS1), and its prognostic effect on the analysis of gene set enrichment in hepatocellular carcinoma Methods:The expressional condition of the YARS1 gene in tumor tissue samples (374 cases) and adjacent tissue samples (50 cases) of hepatocellular carcinoma patients was compared and recorded by mining the Cancer Genome Atlas database. Hepatocellular carcinoma patients were divided into high expression and low expression groups according to this data. Logistic regression was used to analyze the relationship between YARS1 and the clinical pathological characteristics of hepatocellular carcinoma patients. The effect of YARS1 expression on the prognosis of hepatocellular carcinoma patients was analyzed by the Kaplan-Meier method and log-rank test. The prognostic value of the YARS1 gene for hepatocellular carcinoma was analyzed by univariate and multivariate Cox regression. Gene set enrichment analysis was used to evaluate the gene pathways related to YARS1 in the occurrence and development of hepatocellular carcinoma. Results:The expression of the YARS1 gene was higher in hepatocellular carcinoma tissue than in normal tissue ( P<0.001). The expression level of YARS1 was correlated with the grade of patients ( P<0.05), but not with age, gender, TNM stage, and others ( P>0.05). The results of Kaplan-Meier method and log-rank test showed that the survival rate was lower in patients with high YARS1 gene expression than that of patients with low YARS1 gene expression ( P<0.001). The results of multivariate Cox regression analysis showed that YARS1 was used as an independent prognostic factor for hepatocellular carcinoma [hazard ratio=1.10, 95% confidence interval (1.050-1.156), P<0.001]. The results of gene set enrichment analysis showed that YARS1 was involved in pyrimidine metabolism, purine metabolism, aminoacyl tRNA biosynthesis, fatty acid metabolism, ppar signal transduction pathway, oocyte meiosis, amino acid and nucleotide sugar metabolism, RNA degradation, complement pathway, valine and isoleucine degradation, spliceosome, and other pathways. Conclusion:The high expression of YARS1 is associated with the progression and prognosis of hepatocellular carcinoma. Therefore, this gene is expected to become a novel biomarker and a sort of target for biological therapy in hepatocellular carcinoma.

Objective To understand the current status of traditional Chinese medicine(TCM)systematic reviews/Meta-analysis over the past 10 years.Methods Cochrane Database of Systematic Reviews,PubMed,Web of Knowledge,CNKI,SinoMed,WanFang Data,VIP databases,as well as the Cochrane Register and PROSPERO registration platform were searched to collect TCM-related systematic reviews/Meta-analysis published between January 2015 and December 2024.Literature was screened,and standardization of institutions,countries,and journals was performed.Data cleaning was conducted,and trends in publication years,high-frequency diseases,journals,institutions,and highly cited papers were analyzed.Results A total of 11,174 papers were included,involving approximately 56,656 authors from 1,422 institutions across 44 countries,covering 1,300 journals and 1,070 diseases.The top five institutions in terms of publications were Beijing University of Chinese Medicine(954 papers),Guangzhou University of Chinese Medicine(928 papers),China Academy of Chinese Medical Sciences(537 papers),Tianjin University of Chinese Medicine(460 papers),and Chengdu University of Chinese Medicine(393 papers).Foreign institutions with the highest publication volumes were concentrated in South Korea,Iran,and Australia.The most frequently published Chinese journal was Zhongyi Clinical Research with 332 papers,while the most published English journal was Evidence-Based Complementary and Alternative Medicine with 311 papers.There were 282 single-author papers involving 271 authors,and the most cited paper was referenced 323 times,The three most frequently studied diseases were diabetes(267 papers,2.39%),angina pectoris(214 papers,1.92%),and osteoarthritis(210 papers,1.88%).Non-pharmacological interventions such as acupuncture(1,265 papers,11.32%),auricular therapy(101 papers,0.90%),and Tai Chi(98 papers,0.88%)were most frequently reported.In pharmacological interventions,studies on Tripterygium wilfordii tablets(76 papers,0.68%)and Danhong injection(54 papers,0.48%)were more common.Conclusion The systematic reviews/Meta-analysis method is widely used in the field of TCM,and the field continues to grow.Active academic teams,institutions,and journals have emerged.Over the past decade,there has been a considerable body of evidence in Chinese systematic reviews on TCM for chronic diseases such as diabetes,angina pectoris,and osteoarthritis.In English-language studies,non-pharmacological therapies like acupuncture have been more widely reported,and some high-impact studies have emerged.However,challenges remain,such as issues with research transparency and methodological standardization.Future efforts should focus on establishing transparent systems and quality control mechanisms to further enhance the reliability,accuracy,and dissemination of TCM evidence-based research.
