Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

Acquired resistance to the proteasome inhibitor bortezomib(BTZ)poses a significant chal-lenge in the treatment of multiple myeloma(MM).During the acquisition of BTZ resistance,metabolic reprogramming is actively engaged in MM cells.However,the key regulatory genes and molecular mecha-nisms mediating bortezomib resistance through this metabolic rewiring have not been fully elucidated.This study aims to investigate the regulatory role of pyrimidine metabolites in drug resistance of MM and their underlying molecular mechanisms.Screening via CCK-8 assays demonstrated that the pyrimidine metabolite uridine is associated with BTZ resistance in MM(P<0.05).In vitro experiments,including CCK-8 assays,Western blotting,and flow cytometry,demonstrated that uridine partially suppresses bort-ezomib-induced apoptosis in MM cells(P<0.05).In vivo,experiments utilizing Vk*MYC mouse mod-els,subcutaneous tumor models,and intramedullary bone marrow transplantation models showed that the combination of BTZ and uridine significantly accelerated tumor growth,exacerbated bone destruction,and increased tumor cell infiltration in tumor-bearing mice(P<0.05).RNA sequencing analysis re-vealed that uridine primarily affects mitochondrial translation in MM at the transcriptional level.Seahorse energy metabolism assays demonstrated that uridine enhances mitochondrial oxidative phosphorylation without significantly altering glycolysis.Transcriptomic analysis further identified a significant upregula-tion of cytochrome c oxidase subunit 5B(COX5B)transcription in uridine-treated groups(P<0.05).Functional studies confirmed that COX5B is a key molecule mediating uridine's effects on mitochondrial function in MM cells.In conclusion,uridine promotes BTZ resistance in MM by upregulating COX5B transcription and protein expression,thereby enhancing cytochrome c oxidase activity and regulating mito-chondrial oxidative phosphorylation.This study delineates the role of uridine in the development of borte-zomib resistance in MM and elucidates its COX5B-mediated metabolic reprogramming mechanism,provi-ding a theoretical foundation for developing targeted therapies against relapsed/refractory MM.

With the widespread use of antibiotics, drug-resistant bacterial infections have become a significant threat to human health. Finding new antibacterial strategies that can effectively control drug-resistant bacterial infections has become an urgent task. Unlike small molecule drugs that target bacterial proteins, antisense oligonucleotide (ASO) can target genes related to bacterial resistance, pathogenesis, growth, reproduction and biofilm formation. By regulating the expression of these genes, ASO can inhibit or kill bacteria, providing a novel approach for the development of antibacterial drugs. To overcome the challenge of delivering antisense oligonucleotide into bacterial cells, various drug delivery systems have been applied in this field, including cell-penetrating peptides, lipid nanoparticles and inorganic nanoparticles, which have injected new momentum into the development of antisense oligonucleotide in the antibacterial realm. This review summarizes the current development of small nucleic acid drugs, the antibacterial mechanisms, targets, sequences and delivery vectors of antisense oligonucleotide, providing a reference for the research and development of antisense oligonucleotide in the treatment of bacterial infections.

Macroporous resin adsorption column chromatography, silica gel column chromatography, ODS column chromatography, and semi-preparative high-performance liquid chromatography, combined with analytical methods such as NMR and MS, were employed to separate and identify compounds from the 70% ethanol extract of Ajania purpurea. A total of 30 compounds were isolated and identified, including 13 phenolic acids, 7 coumarins, 2 lignans, 1 flavonoid, 2 sesquiterpenes, 1 steroid, and 4 others. Among them, compounds 1 and 2 were newly discovered compounds, and compounds 4, 6, 8, 12, 14-23, 25, 28, and 30 were isolated from Ajania plants for the first time. Bioactivity screening showed that multiple compounds significantly inhibited the production of nitric oxide in lipopolysaccharide-stimulated RAW264.7 cells in a dose-dependent manner. Furthermore, compound 2 elevated the levels of glutathione in LPS-induced BEAS-2B cells, reduced the expression of pro-inflammatory cytokines such as tumor necrosis factor(TNF)-α, interleukin(IL)-6, and IL-1β, enhanced the mRNA of GPX4, HMOX1, NFE2L2, and enhanced protein levels of GPX4, HO-1, Nrf2, and SLC7A11, demonstrating potential anti-ferroptotic effect.
