BACKGROUND: Gluconeogenesis is a critical metabolic pathway for maintaining glucose homeostasis, and its dysregulation can lead to glycometabolic disorders. This study aimed to identify hub biomarkers of these disorders to provide a theoretical foundation for enhancing diagnosis and treatment. METHODS: Gene expression profiles from liver tissues of three well-characterized gluconeogenesis mouse models were analyzed to identify commonly differentially expressed genes (DEGs). Weighted gene co-expression network analysis (WGCNA), machine learning techniques, and diagnostic tests on transcriptome data from publicly available datasets of type 2 diabetes mellitus (T2DM) patients were employed to assess the clinical relevance of these DEGs. Subsequently, we identified hub biomarkers associated with gluconeogenesis-related glycometabolic disorders, investigated potential correlations with immune cell types, and validated expression using quantitative polymerase chain reaction in the mouse models. RESULTS: Only a few common DEGs were observed in gluconeogenesis-related glycometabolic disorders across different contributing factors. However, these DEGs were consistently associated with cytokine regulation and oxidative stress (OS). Enrichment analysis highlighted significant alterations in terms related to cytokines and OS. Importantly, osteomodulin ( OMD ), apolipoprotein A4 ( APOA4 ), and insulin like growth factor binding protein 6 ( IGFBP6 ) were identified with potential clinical significance in T2DM patients. These genes demonstrated robust diagnostic performance in T2DM cohorts and were positively correlated with resting dendritic cells. CONCLUSIONS Gluconeogenesis-related glycometabolic disorders exhibit considerable heterogeneity, yet changes in cytokine regulation and OS are universally present. OMD , APOA4 , and IGFBP6  may serve as hub biomarkers for gluconeogenesis-related glycometabolic disorders.

OBJECTIVE: To conduct a comprehensive analysis of proximal humeral anatomical characteristics in the Chinese population utilizing three-dimensional reconstruction technology, thereby establishing an evidence base for the enhancement of shoulder hemiarthroplasty procedures and the development of domestically manufactured prostheses. METHODS: The study cohort comprised 30 patients (60 shoulders) presenting with cervicoscapular pain between July 2023 and June 2025, with equal gender distribution (15 males and 15 females); age distribution ranged from 20 to 75 years (mean, 53.7 years). Data acquisition was performed via high-resolution CT imaging (technical parameters: slice thickness 0.625 mm, voltage 120 kV, current 150 mA, matrix 512×512). Subsequently, CT datasets were processed in DICOM format using Mimics17.0 software for three-dimensional reconstruction, followed by quantitative assessment via Imageware12.0 software to evaluate key proximal humeral parameters: humeral head dimensions (coronal diameter, sagittal diameter, surface curvature diameter, thickness), angular measurements [neck-shaft angle, retroversion angle (retroversion angle 1 was the angle between the humeral head axis and the line connecting the medial and lateral condyles, and retroversion angle 2 was the angle between the humeral head axis and the tangent of the trochlea)], and positional metrics (medial offset, posterior offset). Statistical analysis incorporated Pearson correlation coefficients to determine parameter relationships, with comparative evaluations conducted across demographic variables including gender, height, body mass, and age. RESULTS: Quantitative analysis yielded the following measurements: humeral head coronal diameter (41.8±3.6) mm, sagittal diameter (39.1±4.1) mm, surface curvature diameter (44.9±4.6) mm, thickness (17.2±1.8) mm, neck-shaft angle (128.4±4.2)°, retroversion angle 1 (16.9±8.9)°, retroversion angle 2 (21.4±11.3)°, medial offset (3.8±1.7) mm, and posterior offset (5.1±1.6) mm. Correlation analysis demonstrated the most pronounced positive relationship between humeral head surface curvature diameter and thickness ( r=0.966, P=0.001), with additional significant positive correlations observed between surface curvature diameter and coronal diameter ( r=0.842, P=0.001), posterior offset and retroversion angle 1 ( r=0.766, P=0.001), and coronal diameter and thickness ( r=0.727, P=0.001). Demographic analysis revealed significantly greater dimensions in males compared to females for humeral head surface curvature diameter, coronal diameter, sagittal diameter, and thickness ( P<0.05), with these parameters demonstrating progressive increases corresponding to height ( P<0.05). With the exception of neck-shaft angle, all parameters exhibited a positive correlation with body mass. No significant age-related differences were detected across parameters ( P>0.05). CONCLUSION The proximal humeral morphology in the Chinese population exhibits substantial variability, necessitating optimization of prosthetic designs based on population-specific anatomical metrics to enhance the efficacy of personalized clinical interventions.

OBJECTIVES: To investigate the characteristics and clinical significance of anorectal manometry measurements in children with tethered cord syndrome (TCS) before and after surgery. METHODS: A retrospective study was conducted on 44 children with TCS treated at the Children's Hospital of Zhejiang University School of Medicine from January 2022 to September 2023. These patients were divided into effective subgroup (n=34) and non-effective subgroup (n=10) based on postoperative symptom improvement. Additionally, 34 children with functional constipation were selected as a control group. Baseline data and manometry measurements were compared between the preoperative TCS group and the control group, as well as between the non-effective and effective subgroups. RESULTS: The TCS group had lower short contraction time and defecation relaxation rate compared to the control group (P<0.05), while defecation residual pressure and maximum rectal tolerable threshold were higher than the control group (P<0.05). The length of the anal canal in the high-pressure zone in the effective subgroup was greater postoperatively than preoperatively (P<0.05), and the initial rectal sensation threshold decreased postoperatively (P<0.05). The non-effective subgroup had lower preoperative maximum rectal expulsion pressure compared to the effective subgroup (P<0.05). Postoperative rectal anal inhibition reflex values in the effective subgroup were higher than those in the non-effective subgroup (P<0.05). CONCLUSIONS There are some differences in anorectal dynamics between children with TCS and those with functional constipation. Maximum rectal expulsion pressure may be a key predictor of surgical outcomes. Surgery can alter certain defecation functions in some children.

OBJECTIVE: To investigate the expression of co-inhibitory molecules TIGIT/CD155 and PD-1 on CD4⁺T cells and Treg cells in peripheral blood of patients with chronic lymphocytic leukemia (CLL) and analyze their clinical significance. METHODS: The expression of PD-1 and TIGIT on CD4⁺T cells and Treg cells was detected by flow cytometry in 40 CLL patients and 20 healthy controls. Additionally, the expression of CD155 on peripheral blood B cells and DC cells of the enrolled subjects was detected. RESULTS: The proportions of PD-1⁺TIGIT⁺CD4⁺T cells, PD-1⁺TIGIT⁺Treg cells and CD155⁺DC cells in peripheral blood of CLL patients were significantly higher than those of healthy controls ( P < 0.05). The proportions of PD-1⁺TIGIT⁺CD4⁺T cells and PD-1⁺TIGIT⁺Treg cells in CLL patients were significantly higher than those of PD-1⁺TIGIT^-CD4⁺T cells and PD-1⁺TIGIT^-Treg cells, respectively ( P < 0.05). Both PD-1⁺TIGIT⁺CD4⁺T cells and PD-1⁺TIGIT⁺Treg cells were positively correlated with the level of CD155⁺DC cells (r =0.742, r =0.766). With the progression of Binet stage, the proportions of PD-1⁺TIGIT⁺CD4⁺T cells, PD-1⁺TIGIT⁺Treg cells, and CD155⁺DC cells gradually increased ( P < 0.05), and the aforementioned three types cells were all increased in patients with CD38≥30%, IGVH unmutated, or poor prognosis due to chromosomal abnormalities ( P < 0.05). CONCLUSION Co-inhibitory molecules PD-1 and TIGIT may be involved in immunodepletion in patients with advanced CLL, which has clinical prognostic value. Dual inhibitor molecular targeted therapy provides a new direction for the individualized treatment of CLL.

OBJECTIVE: To detect and analyze the expression and clinical significance of long non-coding RNA tyrosine kinase non-catalytic region adaptor protein 1-antisense RNA1 (NCK1-AS1) in patients with acute myeloid leukemia (AML). METHODS: 89 AML patients and 23 healthy controls were included from the People's Hospital Affiliated to Jiangsu University. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of NCK1-AS1 and NCK1 in bone marrow samples. The relationship between the expression of NCK1-AS1 and the clinical characteristics of patients were analyzed, as well as the correlation between NCK1-AS1 and NCK1. RESULTS: The expression level of NCK1-AS1 in all AML, non-M3 AML and cytogenetically normal AML (CN-AML) patients was significantly higher than that in the control group (P < 0.01, P < 0.05, P < 0.01, respectively). In non-M3 AML, patients with high NCK1-AS1 expression had a significantly lower hemoglobin level than those with low NCK1-AS1 expression (P =0.036), furthermore, NCK1-AS1 ^high patients had shorter overall survival than NCK1-AS1^low patients (P =0.0378). Multivariate analysis showed that NCK1-AS1 expression was an independent adverse factor in patients with non-M3 AML ( HR =2.392, 95% CI :1.089-5.255, P =0.030). In addition, NCK1 expression was also significantly upregulated in all AML, non-M3 AML and CN-AML patients compared with controls (P < 0.01, P < 0.01, P < 0.001, respectively). There was a certain correlation between NCK1-AS1 and NCK1 expression (r =0.37, P =0.0058). CONCLUSION High expression of NCK1-AS1 in AML indicates poor prognosis of AML patients.

OBJECTIVE: To explore the expression and clinical significance of XPO1 in newly diagnosed adult diffuse large B-cell lymphoma (DLBCL), and further investigate its functional mechanism. METHODS: Immunohistochemical testing was conducted for XPO1 expression in 93 cases of DLBCL and 30 cases of reactive lymphoid hyperplasia. A risk model was construed to find survival related genes in DLBCL patients. Cell proliferation, apoptosis, and cell cycle assays were performed to explore the effect of XPO1 inhibitor (KPT-8602) and XPO1 knockdown. Differential expression gene (DEG) was examined based on the transcriptomes. RESULTS The expression of XPO1 in DLBCL patients was higher than that of the controls. Compared with XPO1 low-expression group, XPO1 high-expression group had a worse prognosis. The constructed risk model indicated that XPO1 and 14 genes in nucleocytoplasmic transport pathway (NTP) might be potential prediction marker of adverse outcome in DLBCL. Moreover, KPT-8602 as well as the XPO1 knockdown could inhibit cell proliferation, promote apoptosis, and induce cell cycle arrest in two DLBCL cell lines, Farage and SU-DHL-4. Based on the gene expression profiling in the datasets of DLBCL, patients were classified into XPO1 high and XPO1 low expression groups, and the MYBL1 was identified as the down-stream effector of XPO1. Inhibiting the function of XPO1 or reducing its expression can significantly decrease the expression of MYBL1 Conclusion: XPO1 is highly expressed in DLBCL, which is associated with poor prognosis. The oncogenic roles of the new XPO1/MYBL1 signaling are identified in DLBCL and XPO1 inhibitor may be a potential option for newly-diagnosed DLBCL patients.

OBJECTIVE: To explore the immunophenotypic characteristics of bone marrow granulocytes (G) and their clinical significance in patients with multiple myeloma (MM). METHODS: The granulocyte immunophenotypes of bone marrow in 70 MM patients (MM group) and 40 anemia patients (control group) were detected by flow cytometry, and its correlation with clinical characteristics was further analyzed. Univariate and multivariate regression analysis were used to screen factors that affected prognosis. RESULTS: The CD56⁺G%, CD13⁺G%, CD22⁺G% and CD117⁺G% in MM group were higher than those in the control group (all P <0.05). CD56⁺G% and CD117⁺G% in CR⁺VGPR group were significantly lower than those in PR+MR+PD group (both P <0.05). The CD10⁺G% in RISS Ⅲ stage and Ca²⁺ ≥2.65 mmol/L groups were increased (both P <0.05). The CD56⁺G% in elevated lactate dehydrogenase, β₂-microglobulin≥5.5 mg/L and hemoglobin <85 g/L groups were increased (all P <0.05), while the CD117⁺G% in high-risk cytogenetic positive group was decreased (P <0.05). The expression rate of CD molecules on granulocytes was divided into low (L) and high (H) groups according to the median value. The overall survival (OS) of the LCD56⁺G%, LCD13⁺G% and LCD22⁺G% groups was significantly prolonged (all P <0.05). CD13⁺G% and CD22⁺G% were independent risk factors for OS in MM patients (HR=0.443, 0.410, both P <0.05). CONCLUSION The CD56⁺G%, CD10⁺G% and CD117⁺G% are closely correlated with clinical features in MM patients, while CD13⁺G% and CD22⁺G% are closely correlated with prognosis. Detection of CD molecules expression on granulocytes may be used to evaluate prognosis and guide treatment.

OBJECTIVE: To investigate the expression and potential mechanism of calcium/calmodulin-dependent protein kinase II gamma (CaMKIIγ) in patients with acute myeloid leukemia (AML). METHODS: Peripheral blood samples were collected from 90 AML patients, and mononuclear cells were isolated. The expression of CaMKIIγ was measured using real-time quantitative PCR and Western blot. The diagnostic value of CaMKIIγ for AML was assessed, and its correlation with clinical characteristics was analyzed using the clinical data of patients. Additionally, the molecular mechanisms of CaMKIIγ were preliminarily explored. RESULTS: Compared with the control group, the expression of CaMKIIγ was significantly upregulated in AML patients. Receiver operating characteristic (ROC) curve analysis showed that CaMKIIγ could serve as a promising biomarker for distinguishing AML patients from healthy individuals. Furthermore, CaMKIIγ was significantly correlated with white blood cell (WBC) count and FLT3-ITD mutation. CaMKIIγ was highly expressed in both newly diagnosed and relapsed AML patients, while decreased during remission. In AML cell lines, the expression levels of CaMKIIγ were all elevated. Inhibition of phosphorylated CaMKIIγ by berbamine led to a decrease in pAKT and pSTAT5 expression. CONCLUSION CaMKIIγ is significantly upregulated in AML patients, and is associated with poor clinicopathological features and unfavorable prognosis. It may serve as a prognostic marker and potential therapeutic target in AML. Its expression may be related to the activation of pAKT and pSTAT5, suggesting that CaMKIIγ may contribute to the development and progression of AML through the activation of the AKT/STAT5 signaling pathway.

OBJECTIVE: To investigate the expression and clinical significance of interleukin-10 (IL-10) and interleukin-15 (IL-15) in patients with multiple myeloma (MM). METHODS: Eighty newly diagnosed MM patients in Department of Hematology in Nanyang First People's Hospital from September 2020 to January 2023 were selected as observation group, and 80 healthy people in our hospital were selected as control group. The expression of IL-10 and IL-15 of the two groups were detected, and survival analysis was conducted for the MM patients. RESULTS: The levels of IL-10 and IL-15 in the observation group before treatment were significantly higher than those in the control group (both P <0.05). The levels of IL-10 and IL-15 in different DS stage had significant differences in MM patients (both P <0.05). The levels of IL-10 and IL-15 in stage II and stage III had no significant differences, which were both significantly higher than those in stage I (both P <0.05). The levels of IL-10 and IL-15 in sCR+CR group after treatment were significantly lower than those before treatment (both P <0.05). The levels of IL-10 and IL-15 in VGPR+PR group after treatment were also significantly lower than those before treatment (both P <0.05), but higher than those in the sCR+CR group (both P <0.05). The progression-free survival (PFS) and overall survival (OS) of patients with IL-10>22.01 pg/ml were significantly shorter than those with IL-10≤22.01 pg/ml (both P <0.001). The PFS and OS of patients with IL-15>48.56 pg/ml were also shorter than those with IL-15≤48.56 pg/ml (both P <0.05). CONCLUSIONS The levels of IL-10 and IL-15 in MM patients are closely related to efficacy and prognosis, and both decreased after treatment. The more reduction, the better effect. Patients with IL-10 and IL-15 below the threshold have longer median PFS and OS.

OBJECTIVE: To investigate the expression of CSF-1 and CSF-1R in the peripheral blood of children with immune thrombocytopenia (ITP) and its clinical significance. METHODS: Forty-four children with ITP treated in our hospital from February 2023 to January 2024 were selected as the observation group, and 40 healthy children were selected as the control group during the same period, and relevant clinical data were collected. Peripheral blood mononuclear cells (PBMC) of children with ITP and healthy children were separated, and the plasma levels of M1 macrophage-associated cytokines (TNF-α, IL-6), M2 macrophage-associated cytokines (IL-10, TGF-β), and CSF-1 were detected by ELISA in the children of both groups. The mRNA levels of M1 macrophage surface markers (CD86, iNOS), M2 macrophage surface markers (CD206, Arg-1) and CSF-1R were detected by RT-PCR in PBMC of children in both groups. Western blot was used to detect the expression of CSF-1R protein in PBMC of the two groups of children. The correlation between platelet count and CSF-1R mRNA expression in PBMC, TNF-α, IL-6, IL-10, TGF-β and CSF-1 in plasma was analyzed. RESULTS: Compared with the control group, the levels of IL-10, TGF-β, CSF-1 and platelet count in plasma of children with ITP were significantly decreased (P < 0.01), and the levels of TNF-α and IL-6 were significantly increased (P < 0.01); the mRNA levels of the M1 macrophage surface markers (CD86, iNOS) in PBMC of children with ITP were significantly increased (P < 0.05), mRNA levels of M2 macrophage surface marker CD206 in PBMC of children with ITP were decreased compared with controls but the difference was not statistically significant ( P >0.05), mRNA levels of Arg-1 were decreased, the difference was statistically significant (P < 0.05). The mRNA and protein levels of CSF-1R in PBMC of ITP children were higher than that in controls. CSF-1R expression in PBMC of ITP was positively correlated with platelet count, IL-10, CSF-1 were positively correlated (r =0.822,0.481,0.405). CONCLUSION CSF-1 is significantly reduced in the plasma of ITP, and CSF-1R mRNA and protein expression is significantly elevated in PBMC of ITP, which are involved in the regulation of macrophage M1/M2 imbalance, and could serve as a potential therapeutic target for ITP.
