ObjectiveTo explore the role of the histone deacetylase Sirtuin-1 (SIRT1)/p53 signaling pathway in promoting apoptosis of non-small cell lung cancer cells (NSCLC) induced by the co-stimulatory molecule B7 homolog 3 (B7-H3). MethodsThe GEPIA 2 platform was used for survival analysis of NSCLC patients based on B7⁃H3 gene expression levels. The Gene Enrichment Analysis (GSEA) method was used to analyze the enrichment characteristics of B7⁃H3 molecules in the gene set of cell apoptosis. In the non-small cell lung cancer A549 cell line, B7⁃H3 was knocked down, and the protein expression levels of SIRT1 and p53 were detected by Western blot. B7⁃H3 was overexpressed in A549 cells and the apoptosis rate was analyzed by flow cytometry after Annexin V/PI double staining. Overexpression of B7⁃H3 and knockdown of SIRT1 were performed in A549 cell line. The expression levels of p53 and apoptosis-related proteins B-cell lymphoma/leukemia-2 (Bcl-2) and Bcl-2-associated X protein (Bax) were detected respectively by Western blot. Cell apoptosis rate was analyzed by flow cytometry after Annexin V/PI double staining. ResultsThe overall survival of the B7-H3 high-expression group was significantly lower than that of the low-expression group (P<0.01). B7-H3 was significantly enriched in the cell apoptosis signaling pathway and the p53 signaling pathway (P<0.05). Compared with the control group, the expression of SIRT1 was significantly downregulated, and p53 was significantly upregulated in the B7⁃H3 knockdown group (both P<0.001). Overexpression of B7-H3 significantly up-regulated SIRT1 protein expression (P<0.05), down-regulated p53 expression (P<0.01), and markedly increased the Bcl-2/Bax ratio of apoptosis-related proteins (P<0.001). The results of Annexin V/PI double staining showed that the apoptosis rate of A549 cells with overexpressed B7⁃H3 decreased (the apoptosis rate of the control group was 26.72%±4.13%, while that of the B7⁃H3 overexpression group was 13.87%±0.82%; P<0.01). In B7-H3-overexpressing cell lines, SIRT1 knockdown significantly reversed apoptosis (P<0.05), up-regulated p53 protein expression (P<0.001), and markedly reduced the Bcl-2/Bax ratio (P<0.001). ConclusionB7-H3 molecule inhibits the apoptosis of non-small cell lung cancer cells via the SIRT1/p53 signaling pathway.

Objective :
To establish an enzyme-linked immunosorbent assay (ELISA) for exosome B7-H3 in plas- ma , and to explore the clinical significance and diagnostic value of exosome B7-H3 in plasma from non-small cell lung cancer (NSCLC) .
Methods :
The plasma of 70 NSCLC patients (NSCLC group) and 36 healthy controls (HC group) were collected . Exosomes and microvesicles in plasma were separated by ultra-fast centrifuge method , and the expression levels of B7-H3 in plasma exosomes in NSCLC groups and HC groups were compared by Western blot method . In NSCLC group , the expression levels of B7-H3 in plasma exosomes and microvesicles in NSCLC group were compared . A simple and feasible ELISA method was established to detect the expression level of exosome B7 - H3 in plasma by means of polyethylene glycol (PEG) precipitation and its clinical significance was analyzed . Lo- gistic regression model was established to predict plasma-derived exosome B7-H3 as a risk factor , and receiver op- erating characteristic curve (ROC) was used to investigate the diagnostic value of exosome B7-H3 in NSCLC .
Results:
For exosomes and microvesicles in plasma which were extracted by ultracentrifugation , Western blot results showed that the expression level of B7-H3 in plasma exosomes of NSCLC group was higher than that of HC group (P = 0. 032) , and the expression level of B7-H3 in plasma exosomes was higher than that of microvesicles of NSCLC group (P = 0. 012) . The expression level of exosome B7-H3 in plasma extracted by PEG precipitation was also higher in NSCLC group than that in HC group (P = 0. 024) . The expression level of exosome B7-H3 in plasma of NSCLC patients was not related to gender , age , smoking or pathological type , but was related to T stage (P = 0. 002) , N stage (P < 0. 001) , M stage (P = 0. 010) and AJCC stage (P < 0. 001) . Multivariate Logistic regres- sion analysis identified exosome B7-H3 in plasma as a risk factor for NSCLC . ROC analysis showed that the sensi- tivity of exosome B7-H3 in plasma for the diagnosis of NSCLC (0. 843) was higher than that of carcinoembryonic antigen (CEA) (0. 743) , whereas the specificity (0. 722) was lower than that of CEA (0. 833) . Combined de- tection of exosome B7-H3 and CEA (AUC = 0. 928 , 95% CI:0. 877 - 0. 979) had a higher diagnostic performance for NSCLC .
Conclusion
B7-H3 in plasma exosomes is related to the cancer staging of NSCLC , and the combined detection of exosome B7-H3 and CEA in plasma is conducive to the laboratory diagnosis of NSCLC .

OBJECTIVES:
To explore the therapeutic mechanism of puerarin for alleviating synovitis in rats with collagen-induced arthritis (CIA).
METHODS:
In a SD rat model of CIA, we tested the effects of daily gavage of puerarin at low, moderate and high doses (10, 30, and 100 mg/kg, respectively) for 3 weeks, with tripterygium glycosides (GTW, 10 mg/kg) as the positive control, on swelling in the hind limb joints regions evaluated by arthritis index scoring. Mass fraction of the liver of the rats was calculated, and pathologies in joint synovial membrane were observed with HE staining. The expressions of transforming growth factor β‑activated kinase-1 (TAK1), Toll-like receptor 4 (TLR4), and nuclear factor kappa-Bp65 (NF‑κB p65) at the mRNA and protein levels in the synovial tissues were detected using Real-time PCR and Western blotting.
RESULTS:
Compared with those in the model group, the rats in GTW group and high-dose puerarin group showed significantly reduced mass fraction of the liver. Treatment with GTW and puerarin at the 3 doses all significantly alleviated plantar swelling, lowered arthritis index scores, and improved synovitis in CIA rats (P<0.05), and the effects of puerarin showed an obvious dose dependence. Both GTW and puerarin treatments significantly lowered TAK1, TLR4, and NF‑κB p65 mRNA and protein expressions in the synovium of CIA rats.
CONCLUSIONS
Puerarin alleviates synovium damages in CIA rats possibly by suppressing the TLR4/NF‑κB signaling pathway via downregulating TAK1 expression.

Objective:To investigate the clinicopathological and molecular genetic characteristics of diffuse gliomas with the features of polymorphous low-grade neuroepithelial tumor of the young (PLNTY) and their prognostic values.Methods:A retrospective analysis was performed on 14 cases of diffuse gliomas with PLNTY features diagnosed at the First Affiliated Hospital of Fujian Medical University, Fuzhou, China from June 2020 to August 2024. Their clinicopathological characteristics were examined, and their molecular genetic and epigenetic features were assessed using next-generation sequencing (NGS) and methylation analysis. Factors influencing prognosis were also analyzed.Results:Among the 14 patients, there were 8 males and 6 females, aged 3-62 years, median 29 (9, 50) years. All cases were initially diagnosed as low-grade diffuse gliomas histologically but exhibited the histological and immunohistochemical features of PLNTY. At the molecular level, all cases showed molecular abnormalities involving the mitogen-activated protein kinase pathway, including 5 cases with FGFR3-TACC3 (F3T3) fusion, 3 cases with FGFR2 fusion, 5 cases with BRAF V600E mutation, and 1 case with FGFR1 mutation. Among them, TERT promoter mutations were frequently observed in tumors with F3T3 fusion (5/5), while NCOR2 in-frame insertion mutations were prominent in tumors with non-F3T3 fusions. Clinical follow-up showed recurrence in 3 cases, all of which had F3T3 fusion and concurrent TERT promoter mutations. Prognostic analysis confirmed that F3T3 fusion with concurrent TERT promoter mutation was associated with poor prognosis.Conclusions:Diffuse gliomas with PLNTY features exhibit heterogeneity in clinicopathology and molecular genetics, with FGFR3/FGFR2 fusions and BRAF/FGFR1 mutations as the most common molecular alteration. They often have concurrent F3T3 fusion and TERT promoter mutations, which are related to poor prognosis. The possibility of molecular glioblastoma should be considered for these tumors. It is thus recommended to perform genetic testing on diffuse gliomas with PLNTY features in order to facilitate integrated diagnosis and provide molecular evidence for accurate evaluation of prognoses.

Objective This study aims to investigate the therapeutic effect and mechanism of Naoxinqing on non-alcohol fatty liver disease (NAFLD) induced by a high-fat diet through network pharmacology,molecular docking and in vitro and in vivo experiments. Methods ApoE-/-mice were given a high-fat diet for 12 weeks to establish the NAFLD model,followed by a 12-week Naoxinqing administration. To evaluate the therapeutic effect of Naoxinqing on NAFLD induced by a high-fat diet,biochemical and histopathological experiments were performed,including assessment of blood lipids,liver function,serum inflammatory factors,as well as Hematoxylin and eosin (HE),Oil red O,and Sirius red staining of liver. Subsequently,network pharmacology and molecular docking techniques were employed to predict the key targets of Naoxinqing. Finally,the mechanism of Naoxinqing was validated by Western Blot in HepG2 cells and liver tissue. Results The results of serum biochemistry and liver tissue pathology showed that Naoxinqing can significantly improve high-fat diet-induced hepatic lipid accumulation,hepatocellular injury,and inflammation. Network pharmacology and molecular docking analysis results suggested that Naoxinqing may affect lipid metabolism through the AMP-activated protein kinase (AMPK)/Sirtuin 1 (SIRT1) pathway. Finally,in vitro cell experiment confirmed that the main mechanism of Naoxinqing is to activative the AMPK/SIRT1 pathway,upregulate the expression of downstream carnitine palmitoyltransferase 1 (CPT1A),promote fatty acid oxidation,and ultimately improve NAFLD. Conclusion This study demonstrated that Naoxinqing improved NAFLD by promoting fatty acid oxidation through the activation of the AMPK/SIRT1 pathway.
