With the widespread use of antimicrobial agents, bacterial drug resistance has become an increasingly severe issue, posing significant challenges to global healthcare. Traditional Chinese medicine (TCM) has emerged as a research focus in the field of bacterial resistance due to its broad sources, high safety profile, low toxicity, and antimicrobial mechanisms distinct from those of chemical drugs. Studies have shown that various TCM herbs, such as Scutellaria baicalensis, exert antibacterial effects through multiple pathways, including disrupting the integrity of bacterial cell walls and membranes, inhibiting nucleic acid and protein synthesis, and impairing energy production and metabolism. Additionally, certain TCM herbs, including Scutellaria baicalensis, Coptis chinensis, and Fritillaria thunbergii, can reverse antimicrobial resistance by eliminating resistant plasmids, inhibiting bacterial efflux pump function, and suppressing β-lactamase activity. TCM holds promising potential for antibacterial applications and synergistically reversing antimicrobial resistance, though systematic analyses remain limited. This review summarizes the mechanisms of antibacterial action of TCM and current research on its synergistic use with antimicrobial agents to reverse drug resistance, aiming to provide insights for developing novel TCM-based antimicrobials and addressing bacterial resistance.

Objective: To elucidate the molecular mechanism by which prohibitin 2(PHB2) mediates periodontitis-induced bone tissue inflammation through regulating the nuclear factor kappa B(NF-κB) signaling pathway and its role in irreversible alveolar bone resorption. Methods: Quantitative real-time reverse transcription polymerase chain reaction(qRT-PCR) and immunohistochemistry(IHC) were used to detect the expression differences of inflammatory factors and PHB2 in healthy and inflamed alveolar bone tissues of mice in vivo. In vitro, an inflammatory model was established using lipopolysaccharide(LPS)-induced a mouse calvaria-derived preosteoblastic cell line, subclone E1(MC3T3-E1) cells. Western blot and qRT-PCR were used to clarify the regulatory relationship between PHB2 and inflammatory factors, and immunofluorescence staining was performed to observe changes in PHB2 subcellular localization. PHB2 overexpression plasmids were constructed using molecular cloning, and RNA interference was employed to knock down PHB2 expression to assess its regulatory role in inflammation. Based on RNA-seq data, differential expression analysis based on the negative binomial distribution, version 2(DESeq2) was used for differential expression analysis, and kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment along with gene ontology(GO) functional annotation were performed to identify key signaling pathways and differentially expressed genes. Results: In the mouse periodontitis model, PHB2 expression was significantly upregulated in alveolar bone tissues. In the in vitro inflammatory cell model, PHB2 levels positively correlated with interleukin(IL)-6, IL-1β, and tumor necrosis factor-alpha(TNF-α) levels, and its subcellular localization shifted during inflammation. RNA-seq data and the detection of the level of phosphorylation of p65 protein(p-p65) demonstrated that PHB2 exacerbated inflammatory responses through the NF-κB signaling pathway and was mechanistically linked to upregulation of the upstream chemokine C-X-C motif chemokine ligand 10(CXCL10). Conclusion PHB2 aggravates LPS-induced periodontitis inflammation via the NF-κB signaling pathway, providing new insights into the molecular mechanisms underlying the development of periodontitis.

Objective To investigate the characteristics of the relative electroencephalogram(EEG)power spectrum in cerebral in-farction patients with different lesion locations and neurological deficit severities.Methods From February,2024 to May,2025,70 patients with cerebral infarction who completed EEG examinations at Shijiazhuang People's Hospital were enrolled.They were divided into cortical group(n=19)and subcortical group(n=51)based on admission MRI/CT imaging,and divided into mild group(n=53)and moderate-to-se-vere group(n=17)according to the scores of National Institutes of Health Stroke Scale(NIHSS)and Barthel In-dex.All patients underwent 32-channel video-EEG monitoring.The power spectral density of α and θ waves,and the(δ+θ)/(α+β)ratio(DTABR)were analyzed in eight electrodes of F3,F4,P3,P4,T3,T4,O1 and O2.Results DTABR was higher in the cortical group than in the subcortical group across all eight electrodes(|Z|≥2.047,P<0.05),while the relative power decreased in α waves(|Z|≥1.968,P<0.05),and increased in θ waves(|Z|≥1.988,P<0.05)in the cortical group.DTABR was higher in the moderate-to-severe group than in the mild group(|Z|≥2.263,P<0.05).Conclusion Elevated DTABR suggests cortical involvement or more severe neurological impairment,and decreased αwave and increased θ wave activity are primarily observed in patients with cortical lesions,potentially serving as EEG indicators for identifying cortical involvement.

Corynebacterium pseudotuberculosis(C.pseudotuberculosis)is a group of intracellular Gram-positive bacteria that can cause zoonotic diseases.This study investigated the mechanisms of inflammatory mediator secretion and the phagocytic and bactericidal functions of mouse peritoneal macrophages following C.pseudotuberculosis infection.Initially,transcriptomic sequencing was em-ployed to identify genes critical for C.pseudotuberculosis infection in macrophages.Subsequently,gene knockout mice were utilized to assess the impact of these key genes on inflammatory media-tor secretion,activation of inflammatory signaling pathways,and the phagocytic and bactericidal functions of macrophages infected with C.pseudotuberculosis.Techniques such as ELISA,Western blot,and immunofluorescence were employed in this analysis.Further,transcriptomic sequencing was conducted to identify key downstream genes.Following C.pseudotuberculosis infection,GO enrichment analysis was performed,and TLR2 was identified as the focal point of the study.Perito-neal macrophages from C57BL/6J and TLR2 knockout(TLR2-/-)mice were infected with C.pseudotuberculosis.ELISA results revealed that the levels of TNF-α,IL-1β,and IL-10 were signifi-cantly downregulated in TLR2-/-macrophages compared to C57BL/6J macrophages post-infec-tion.Western blot demonstrated that the absence of TLR2 led to a marked decrease in M APK(p38 and ERK)signaling pathway phosphorylation following C.pseudotuberculosis infection.Immuno-fluorescence results indicated that the phagocytic rate of TLR2-/-macrophages was significantly higher than that of C57BL/6J macrophages after infection.Subsequently,transcriptomic analysis of C57BL/6J and TLR2-/-macrophages infected with C.pseudotuberculosis was performed,followed by GO enrichment analysis of differential genes.IL-36a,Cx3cr1,TLR1,and TLR2 were identified as key differential genes.TLR2 plays a crucial role in the inflammatory response induced by C.pseudotuberculosis infection in mice,influencing the progression of the inflammatory response and host outcomes through the secretion of inflammatory mediators,activation of signaling pathways,and modulation of phagocytic and bactericidal functions.IL-36a and Cx3cr1 were identified as key downstream factors in this process.

Objective To explore the psychological feelings and coping resources of patients waiting for a liver transplantation,in order to provide references for implementing psychological nursing care.Methods Using purposive sampling,15 patients waiting liver transplantation surgery from June to November 2024 at a tertiary hospital in Qingdao were selected as study subjects.Semi-structured in-depth interviews were conducted,and data were analyzed using interpretative phenomenological analysis to extract themes.Results The psychological feelings of patients waiting for a liver transplantation included 2 main themes with 6 sub-themes,namely,the complex and contradictory psychological feelings of liver transplant patients during the waiting period(expectations for transplanta-tion and future outlook,multiple psychological burdens intertwining,introspection and growth),and mobilizing psychological resilience resources to deal with complex psychological feelings(core resources,internal resources,external resources).Conclusion Clinical medical staff should implement psychological care for patients waiting for a liver transplantation based on the complex and contradictory psychological feelings they experience.Also,they should target the coping resources for psychological feelings to construct coping strategies,thereby comprehensively improving patients' psychological health during the waiting period.The coping strategies include promoting patients' health behaviors,improving their psychological status,and providing multidimensional social support for them.
