This study aimed to explore the therapeutic mechanisms of Colquhounia Root Tablets(CRT) in treating diabetic kidney disease(DKD) by integrating biomolecular network mining with animal model verification. By analyzing clinical transcriptomics data, an interaction network was constructed between candidate targets of CRT and DKD-related genes. Based on the topological eigenvalues of network nodes, 101 core network targets of CRT against DKD were identified. These targets were found to be closely related to multiple pathways associated with type 2 diabetes, immune response, and metabolic reprogramming. Given that immune-inflammatory imbalance driven by metabolic reprogramming is one of the key pathogenic mechanisms of DKD, and that many core network targets of CRT are involved in this pathological process, receptor for advanced glycation end products(RAGE)-reactive oxygen species(ROS)-phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT)-nuclear factor-κB(NF-κB)-NOD-like receptor family pyrin domain containing 3(NLRP3) signaling axis was selected as a candidate target for in-depth research. Further, a rat model of DKD induced by a high-sugar, high-fat diet and streptozotocin was established to evaluate the pharmacological effects of CRT and verify the expression of related targets. The experimental results showed that CRT could effectively correct metabolic disturbances in DKD, restore immune-inflammatory balance, and improve renal function and its pathological changes by inhibiting the activation of the RAGE-ROS-PI3K-AKT-NF-κB-NLRP3 signaling axis. In conclusion, this study reveals that CRT alleviates the progression of DKD through dual regulation of metabolic reprogramming and immune-inflammatory responses, providing strong experimental evidence for its clinical application in DKD.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex disease that is often accompanied by mental health disorders. However, the potential mechanisms underlying the heterogeneous clinical presentation of CP/CPPS remain uncertain. This study analyzed widely targeted metabolomic data of expressed prostatic secretions (EPS) and plasma to reveal the underlying pathological mechanisms of CP/CPPS. A total of 24 CP/CPPS patients from The Second Nanning People's Hospital (Nanning, China), and 35 asymptomatic control individuals from First Affiliated Hospital of Guangxi Medical University (Nanning, China) were enrolled. The indicators related to CP/CPPS and psychiatric symptoms were recorded. Differential analysis, coexpression network analysis, and correlation analysis were performed to identify metabolites that were specifically altered in patients and associated with various phenotypes of CP/CPPS. The crucial links between EPS and plasma were further investigated. The metabolomic data of EPS from CP/CPPS patients were significantly different from those from control individuals. Pathway analysis revealed dysregulation of amino acid metabolism, lipid metabolism, and the citrate cycle in EPS. The tryptophan metabolic pathway was found to be the most significantly altered pathway associated with distinct CP/CPPS phenotypes. Moreover, the dysregulation of tryptophan and tyrosine metabolism and elevation of oxidative stress-related metabolites in plasma were found to effectively elucidate the development of depression in CP/CPPS. Overall, metabolomic alterations in the EPS and plasma of patients were primarily associated with oxidative damage, energy metabolism abnormalities, neurological impairment, and immune dysregulation. These alterations may be associated with chronic pain, voiding symptoms, reduced fertility, and depression in CP/CPPS. This study provides a local-global perspective for understanding the pathological mechanisms of CP/CPPS and offers potential diagnostic and therapeutic targets.

Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe₃O₄ loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4⁺/CD8⁺ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.

Instrument separation is a critical complication during root canal therapy, impacting treatment success and long-term tooth preservation. The etiology of instrument separation is multifactorial, involving the intricate anatomy of the root canal system, instrument-related factors, and instrumentation techniques. Instrument separation can hinder thorough cleaning, shaping, and obturation of the root canal, posing challenges to successful treatment outcomes. Although retrieval of separated instrument is often feasible, it carries risks including perforation, excessive removal of tooth structure and root fractures. Effective management of separated instruments requires a comprehensive understanding of the contributing factors, meticulous preoperative assessment, and precise evaluation of the retrieval difficulty. The application of appropriate retrieval techniques is essential to minimize complications and optimize clinical outcomes. The current manuscript provides a framework for understanding the causes, risk factors, and clinical management principles of instrument separation. By integrating effective strategies, endodontists can enhance decision-making, improve endodontic treatment success and ensure the preservation of natural dentition.

Objective·To investigate the effects of the cancer-testis antigen 14(CT14)on embryonic and larval development in nematodes by using the model organism Caenorhabditis elegans(C.elegans),aiming to uncover its potential functions and mechanisms during development.Methods·Transgenic C.elegans strains were constructed by using microinjection for the inducible expression of human CT14(HsCT14),a truncated mutant of CT14(HsCT14?CIR)lacking CT14-specific intermediate region(CIR),and a green fluorescent protein(GFP)control.The impacts of full-length and truncated mutant CT14 on nematode embryonic and larval development were analyzed and compared.Additionally,transgenic C.elegans strains with inducible expression of CT14 from various primates,including the crab-eating macaque(Macaca fascicularis)and mouse lemur(Microcebus murinus),were also constructed to assess the effects on egg hatching and larval-to-adult transformation rates.The differential gene expression in nematode embryos induced by CT14 was analyzed by Smart-seq transcriptome sequencing,with further insights gained through KEGG(Kyoto Encyclopedia of Genes and Genomes)and GSEA(Gene Set Enrichment Analysis),to explore the involved biological processes and pathways.Results·The induced expression of HsCT14 and its truncated mutant HsCT14?CIR significantly reduced the hatching rate of nematode eggs,with a more pronounced effect observed in HsCT14-expressing strains.Differential interference contrast(DIC)microscopy imaging revealed significant morphological abnormalities in embryos expressing HsCT14 during the comma stage.Nematodes expressing HsCT14 or HsCT14?CIR exhibited developmental arrest in larvae and substantially lower larval-to-adult transformation rates compared to the GFP control.The impact was more pronounced in nematodes expressing HsCT14 than those with HsCT14?CIR.The expression of Macaca fascicularis CT14(MfCT14)exhibited significant effects on the hatching rate and adult transformation rate,similar to that of HsCT14,while the expression of Microcebus murinus CT14(MmCT14)displayed significantly reduced impact compared to HsCT14 and MfCT14.Smart-seq results indicated that CT14 expression affected various biological processes in nematode embryos,related to ATP-dependent chromatin remodeling and DNA replication.Conclusion·Ectopic expression of the cancer-testis antigen CT14 significantly disrupts both embryonic and larval developments in C.elegans,with the CIR sequence substantially enhancing this effect.It suggests that CT14 may play an important regulatory role in biological development by affecting gene expression in multiple pathways,including chromatin remodeling.

AIM To investigate the effects of diosgenin on autophagy of human osteosarcoma cells.METHODS Human osteosarcoma MG63 and U2OS cells with or without exposure to diosgenin had their proliferation detected by MTT assay,their ultrastructure observed by transmission electron microscopy,their expression of autophagy protein Beclin1 observed by immunofluorescence staining,and their expressions of autophagy molecular markers LC3,Beclin1 and PI3K/Akt/mTOR signaling pathway related proteins detected by Western blot.The MG63 and U2OS cells cotreated with diosgenin and PI3K pathway inhibitor LY294002 had the expression of Beclin1 mRNA detected by RT-qPCR.The MG63 and U2OS cells cotreated with autophagy inhibitor 3-methyladenine(3-MA)had their inhibition rate of proliferation detected by MTT assay,their expression of cleaved-caspase3 protein detected by Western blot,and their expression of caspase3 mRNA detected by RT-qPCR.RESULTS Upon osteosarcoma MG63 and U2OS cells,diosgenin inhibited their proliferation,promoted the generation of autophagosomes,increased the protein expression of LC3 Ⅱ and Beclin1(P<0.05,P<0.01),reduced the protein expression of LC3 I(P<0.01),and inhibited the protein phosphorylation level of PI3K/Akt/mTOR pathway(P<0.05,P<0.01),whose effects were offset by the intervention with autophagy inhibitors in terms of the reduced proliferation inhibition and down-regulated expressions of caspase3 mRNA and cleaved-caspase3 protein(P<0.01).CONCLUSION Diosgenin can inhibit the proliferation of osteosarcoma cells and induce their autophagy leading to their death and autophagy apoptosis,which may be related to the activation of PI3K/Akt/mTOR signaling pathway and up-regulation of the expression of LC3 Ⅱ and Beclin1 proteins.

Objective:To evaluate the gene mutation profile and prognostic significance of adult cytogenetically normal acute myeloid leukemia (CN-AML) with CEBPA-bZIP mutation. Methods:Targeted sequencing was implemented on the diagnostic bone marrow DNA samples of 141 adult CN-AML subjects with CEBPA-bZIP mutation. The nomogram model for leukemia-free survival (LFS) rate was generated by combining genetic abnormalities and clinical data. Risk stratification was conducted based on prognostic variables and the effect of risk-adjusted consolidation therapy was investigated by Kaplan-Meier method. Results:Four variables were finally included in our nomogram model after multivariate Cox analysis,and an equation for risk score calculation was obtained,risk score=1.3002×white blood cell (WBC) (≥18.77×109/L)+1.4065×CSF3R mutation positive+2.6489×KMT2A mutation positive+1.0128×DNA methylation-related genes mutation positive. According to the nomogram model,patients were further divided into low-risk group (score=0,n=46) and high-risk group (score>0,n=95). Prognostic analysis showed that the 5-year LFS rate,5-year overall survival (OS) rate,and 5-year cumulative incidence of relapse (CIR) of patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the high-risk group were 93.5％,97.1％,and 3.5％,while those in patients who received maintenance chemotherapy were 32.9％,70.5％,and 63.4％,respectively. The differences were statistically significant (all P<0.05). Allo-HSCT could significantly improve the prognosis of patients in high-risk group. However,no corresponding benefit was observed in the low-risk group. Conclusion:Adult CN-AML with CEBPA-bZIP mutation has a complex co-mutation pattern. The nomogram model based on mutations of CFS3R,KMT2A and DNA methylation-related genes together with WBC count can further divide this subset of patients into a relatively low-risk group and a relatively high-risk group. For individuals in the high-risk group,allo-HSCT is proposed as post-remission therapy. The above data will benefit the prognosis estimation and treatment decision for adult CN-AML with CEBPA-bZIP mutation.
