AIM: To investigate the diagnostic and prognostic value of differential expression of Cyclin D1 and p53 in eyelid tumors.METHODS: This retrospective study enrolled patients who underwent surgical resection for eyelid tumors at our hospital between March 2018 and March 2023. Participants were categorized into benign and malignant groups based on tumor characteristics. Clinical data were collected. Genetic data for eyelid tumors were obtained from the GEO database, and differential gene analysis, including volcano plot visualization and KEGG pathway enrichment analysis, was performed using the Sangerbox 3.0 platform. Immunohistochemistry was used to detect the expression levels of Cyclin D1, p53, and BAX in tissue samples. Correlations with clinical features were analyzed using Spearman analysis, and prognostic factors were identified via Logistic regression analysis.RESULTS: This study included 69 patients with eyelid tumors(78 eyes), categorized into a benign group(37 patients, 41 eyes)and a malignant group(32 patients, 37 eyes)based on tumor characteristics. There were significant differences between the two groups in histological subtype, TNM staging, vascular invasion, differentiation status, and local infiltration(all P<0.05). Among benign tumors: pigmented nevi in 11 eyes(27%), hemangiomas in 9 eyes(22%), squamous cell papillomas in 5 eyes(12%), epidermoid cysts in 5 eyes(12%), seborrheic keratoses in 4 eyes(10%), neurofibromas in 3 eyes(7%), and both calcifying epithelioma and xanthelasma in 2 eyes each(5%); among malignant tumors: basal cell carcinoma in 18 eyes(49%), meibomian gland carcinoma in 8 eyes(22%), squamous cell carcinoma in 5 eyes(14%), sebaceous gland carcinoma in 4 eyes(11%), lymphoma and malignant melanoma each in 1 eye(3%). At the follow-up cutoff date of March 2025, the 2-year survival rate in the benign group(95%)was significantly higher than that in the malignant group(78%; P<0.05). Bioinformatics analysis identified 4 103 differentially expressed genes, including Cyclin D1, p53, and BAX, which were predominantly involved in pathways such as the p53 signaling pathway and calcium-related signaling. Spearman analysis revealed that local invasion(rs=0.71, P<0.05)and TNM stage(rs=0.73, P<0.05)correlated with Cyclin D1 expression; local invasion(rs=0.76, P<0.05)and histological subtype(rs=0.65, P<0.05)correlated with p53 expression. Logistic regression results indicated that Cyclin D1, p53, TNM staging, and local invasion were prognostic risk factors. ROC curve analysis demonstrated that the combined detection of these four indicators had the highest predictive value for prognosis(AUC=0.83).CONCLUSION: High expression of cyclin D1 and p53 serves as molecular markers for distinguishing benign from malignant eyelid tumors and assessing prognosis. Combined detection of these markers with TNM staging and local invasion demonstrates high predictive value for prognosis.

ObjectiveTo investigate the protective effect of α-ketoglutarate （α-KG） on hepatic lipid deposition in offspring caused by arsenic exposure during pregnancy. Methods8-week-old institute of cancer research （ICR） mice were mated in a ratio of 2∶1 between females and males， and the detection of vaginal plugs confirmed pregnant. A total of 32 pregnant mice were randomly divided into four groups： control group， arsenic group， α-KG group， arsenic+α-KG group. On gestational day 0-16 （GD0-GD16）， the arsenic and arsenic+α-KG groups were exposed to sodium arsenite （NaAsO₂ ，15 mg/L） in drinking water everyday， and the α-KG and arsenic+α-KG groups were gavaged with α-KG （2 g/kg） everyday. On GD16， pregnant mice were euthanized to collect fetal liver， and fetal body weight and crown-rump length were measured. Gene expression differences between the control group and the arsenic group were analyzed by transcriptome. The total triglycerides （TGs） and subtypes in fetal liver were detected by liquid chromatography tandem mass spectrometry （LC-MS/MS）. Oil red O staining was used to observe the histopathological changes in the liver. Quantitative polymerase chain reaction （qPCR） was used to detect the expression level of genes related to lipid synthesis， transport， and degradation， and phosphatidylinositol 3' -kinase/ protein kinase B （PI3K/AKT） in the liver of fetus. ResultsTranscriptomics analysis showed that 2 144 genes were downregulated and 1 675 genes were upregulated in the arsenic exposed fetal liver； body weight and crown-rump length were reduced （P_TuKey<0.05）； the level of hepatic TGs was elevated in arsenic group （P_TuKey<0.05）； oil-red O staining showed a significant increase in lipid droplets in arsenic group （P_TuKey<0.01）； the expression of lipid synthesis-related genes were significantly upregulated （P_TuKey<0.05）； the expression of β-oxidation-related genes and lipid degradation-related genes were downregulated （P_TuKey<0.05）； the expression of PI3K， AKT decreased（P_TuKey<0.05）. Compared with the arsenic group， the body weight and crown-rump length of fetus increased in the arsenic+α-KG group （P_TuKey<0.05）； the level of hepatic TGs decreased in the arsenic+α-KG group （P_TuKey<0.05）； oil red O staining showed lipid droplets significantly decreased （P_TuKey<0.01）； the expression of lipid synthesis-related genes were downregulated （P_TuKey<0.05）， the expression of β-oxidation-related genes and lipid degradation-related genes were upregulated （P_TuKey<0.05）； the expression levels of PI3K and AKT increased （P_TuKey<0.05）. Conclusionα-KG alleviated hepatic lipid deposition in offspring exposed to arsenic during pregnancy through activating PI3K/AKT signaling pathway.

BackgroundWith the acceleration of population aging in China， studies have documented an increased prevalence of dementia in the elderly. Behavioral and psychological symptoms and impaired cognitive function are important problems affecting the quality of life in the elderly with dementia. It has been noted that there are certain limitations on the management of problems mentioned above by drug treatment alone， while its combination with music intervention is emerging as an effective approach. However， the application of this approach in the elderly with moderate to severe dementia is still in its relative infancy. ObjectiveTo investigate the effect of music assisted drug treatment on behavioral and psychological symptoms and cognitive function in the elderly with moderate to severe dementia， so as to provide insights for the development of effective intervention. MethodsA randomized controlled study was utilized to enroll a coherent of 43 elderly patients with moderate to severe dementia who were hospitalized in Geriatric Psychiatry of Deyang Mental Health Center from January to July 2023 and met the International Classification of Diseases， tenth edition （ICD-10） diagnostic criteria for dementia. Eligible subjects were divided into study group （n=22） and control group （n=21） based on random allocation using SPSS 26.0. Both groups received routine drug treatment and nursing care， while the study group added music intervention， which consisted of two 30-minute sessions per week for 8 weeks. Neuro Psychiatric Inventory （NPI） and Mini-Mental State Examination （MMSE） were administered to all patients before and after intervention. ResultsA total of 36 patients completed the study， including 20 case in study group and 16 case in control group. No statistical difference was noted in baseline NPI score and MMSE score between two groups （P>0.05）. After intervention， study group reported a statistical reduction in NPI total score ［58.00 （49.00， 79.25） vs. 78.50 （55.00， 95.50）， Z=-3.902， P<0.01）］ along with a clinically unremarkable increase in MMSE score （P>0.05） compared with baseline data. After intervention， NPI total score and scores on sub-domains including agitation/aggression， depression/dysphoria， anxiety and aberrant motor behavior were all significantly lower in study group than those in control group （Z=-2.183， -2.438， -2.691， -3.716， -2.250， P<0.05 or 0.01）， while there was no significant difference in MMSE score between two groups （P>0.05）. ConclusionMusic assisted drugintervention may ameliorate behavioral and psychological symptoms in the elderly with moderate to severe dementia， while no significant improvement is documented on cognitive function. ［Fund by the "14^th Five Year Plan" for Philosophy and Social Sciences Research in Deyang （number， DY232C002）］

Objective To investigate the impact of pomegranate peel polyphenols(PPP)on the malignant biological behavior of colon cancer cells through modulation of the miR-138-5p/hypoxia-inducible factor-1α(HIF-1α)pathway.Methods Quantitative real-time PCR(qRT-PCR)was employed to measure the expression levels of miR-138-5p and HIF-1α mRNA in the normal colon epithelial cell line FHC and three colorectal cancer cell lines:SW480,HCT116,and Caco-2.SW480 cells were divided into six groups:a blank control group,a negative control(mimics NC)group,a miR-138-5p mimics group,three different concentrations of PPP treatment groups(0.5 mg/mL,1 mg/mL,and 2 mg/mL),a PPP+inhibitor NC group at 2 mg/mL,and a PPP+miR-138-5p inhibitor group at 2 mg/mL.The effects on cell proliferation,invasion,and migration,as well as changes in apoptosis and related proteins including B-cell lymphoma 2(Bcl-2),migration invasion enhancer 1(MIEN1),and Cyclin D1,were evaluated separately.Additionally,the targeting relationship between miR-138-5p and HIF-1α was validated.The expression levels of miR-138-5p,HIF-1α mRNA,and protein were assessed in each experimental group.Results The expression levels of miR-138-5p were highest in FHC cells and lowest in SW 480 cells,while the expression levels of HIF-1α mRNA showed an opposite trend,being lowest in FHC cells and highest in SW 480 cells(P<0.05).Compared with the control group,different concentrations of PPP significantly promoted cell apoptosis,upregulated miR-138-5p expression,inhibited cell proliferation,invasion,and migration,and downregulated the expression of HIF-1α mRNA,Bcl-2,MIEN1,CyclinD1,and HIF-1α protein,with significant differences between groups(P<0.05).Compared with the mimics NC group,the miR-138-5p mimics group significantly enhanced cell apoptosis,upregulated miR-138-5p expression,inhibited cell proliferation,invasion,and migration,and downregulated the expression of HIF-1α mRNA,Bcl-2,MIEN1,CyclinD1,and HIF-1α protein(P<0.05).Compared with the 2 mg/mL PPP+inhibitor NC group,the 2 mg/mL PPP+miR-138-5p inhibitor group significantly suppressed cell apoptosis,downregulated miR-138-5p expression,promoted cell proliferation,invasion,and migration,and upregulated the expression of HIF-1α mRNA,Bcl-2,MIEN1,CyclinD1,and HIF-1α protein(P<0.05).These results indicate a targeted relationship between miR-138-5p and HIF-1α(P<0.05).Conclusion PPP inhibits the malignant biological behavior of colon cancer cells through upregulation of the miR-138-5p/HIF-1α pathway.

Objective To investigate the effects of long-term radiofrequency(RF)radiation at 2.65 GHz on behavior,inflammatory response,and intestinal microecology in mice in order to provide a basis for the safety assessment of long-term RF exposure.Methods One hundred and eight male C57BL/6N mice(17～21 g,6～8 weeks old)were randomly assigned to a control group(Con)and a RF exposure group.The mice of the RF exposure group were subjected to whole-body uniform exposure to 2.65 GHz RF radiation in an electromagnetic reverberation chamber for 3 h/day for 28 consecutive days.RF field distribution and changes in core body temperature were monitored using an electromagnetic radiation analyzer and a fiber-optic temperature probe,respectively.Cognitive function was assessed using the Y-maze and novel object recognition(NOR)test.Anxiety-like behaviors were evaluated through open field test(OFT)and elevated plus maze(EPM),while depressive-like behaviors were examined with sucrose preference test(SPT)and tail suspension test(TST).HE staining was used to observe the histopathological changes in mouse tissues.Radioimmunoassay(RIA)was employed to detect the expression of pro-inflammatory cytokines,TNF-α and IL-1 β,as well as anti-inflammatory cytokines,IL-4 and IL-10 in the serum,brain,jejunum,and spleen samples.Additionally,metagenomic sequencing was performed to assess alterations in the gut microbiota composition.Results Long-term RF radiation led to a maximal increase of 0.59℃in the core body temperature,but had no significant effects on cognitive function,anxiety-like behaviors,or depressive-like behaviors,or apparent damage of the hippocampal or jejunal tissues in the exposed mice.However,RF exposure significantly up-regulated the expression of the pro-inflammatory cytokine TNF-α in serum(P<0.05),and did not significantly alter the concentrations of other cytokines(IL-1β,IL-4,IL-10),caused significant decrease in α-diversity of the intestinal microbiota(P<0.01),with reduced relative abundances of Ligilactobacillus murinus and Acetatifactor muris(P<0.05),while elevated abundances of Lachnospiraceae bacterium(P<0.01).Conclusion Long-term exposure to 2.65 GHz RF radiation induces systemic inflammatory responses and disrupts gut microbiota homeostasis in mice.

The incidence of malignant tumors among elderly patients is increasing.Influenced by multiple factors such as aging,tumor,and drug,this population exhibits a high prevalence of renal insufficiency.However,there remains a scarcity of research data and significant challenges in clinical management.This article systematically an-alyzes the challenges faced in administering anti-tumor therapies to elderly patients with renal insufficiency and pro-poses management strategies.Optimization approaches include precise assessment of renal function,selection of nephrotoxicity-sparing medications,appropriate dose adjustments,implementation of preventive measures,and em-phasis on comprehensive geriatric assessment and multidisciplinary collaboration.Renal injury management should be individualized,with considerations for special populations such as renal transplant recipients and dialysis pa-tients.Future efforts should focus on biomarker discovery and the development of low-nephrotoxicity therapeutic agents to address these complex clinical challenges.

Objective:To investigate the potential characteristic manifestations and application value of the Dynamic Visual Acuity Test（DVAT） in vestibular migraine（VM）. Methods:A total of 50 VM patients（case group） and 50 healthy subjects（control group） diagnosed at the Department of Otorhinolaryngology Head and Neck Surgery, First Hospital of Shanxi Medical University between November 1, 2023, and December 31, 2024, were enrolled. The case group underwent DVAT, video head impulse test（vHIT）, caloric test, and Dizziness Handicap Inventory（DHI） assessment, whereas the control group only received DVAT. Group-based analyses were conducted to examine the effect of age on Dynamic Visual Acuity Loss（DVALoss）, as well as the correlations of DVALoss with vestibular function tests and DHI scores. Results:DVALoss in the case group was significantly higher than that in the control group（P<0.001）. In both groups, age was significantly and positively correlated with DVALoss（P<0.001）. Within the case group, DVALoss was strongly and positively correlated with DHI scores（r=0.807, P<0.001）; it was negatively correlated with the vestibulo-ocular reflex（VOR） gain in vHIT, though without clinical significance, and showed no significant association with the caloric test. Age and DVALoss collectively accounted for 71.3% of the variance in DHI scores（R²=0.713）, with age exerting a relatively minor actual impact. Conclusion:DVAT can sensitively identify the core functional impairments of VM. DVALoss, as a direct functional reflection of the pathological mechanism of VM, is strongly correlated with DHI scores. Incorporating DVALoss into standardized assessments may provide an objective basis for the diagnosis and management of VM.

Advanced atherosclerosis is the major global cause of death, as featured by the aggregation of apoptotic cells (ACs) in necrotic cores. The defective efferocytosis and dysfunctional cholesterol efflux of macrophages are the main reasons for forming necrotic cores in advanced atherosclerosis. In this study, we constructed self-assembled procyanidins (PC) NPs for loading pitavastatin (Pita). The designed HA@PC@Pita NPs with hyaluronic acid (HA) modification combined the advantages of efferocytosis restoration of Pita and cholesterol efflux enhancement of PC. In vitro assay indicated that HA@PC@Pita NPs could induce M1/M2 repolarization and upregulate ERK5/Mertk expression to restore efferocytosis of macrophages. Simultaneously, HA@PC@Pita NPs notably promoted cholesterol efflux by promoting macrophage lipophagy, a selective autophagy of lipid droplets. In vivo study showed that HA@PC@Pita NPs cleared necrotic core and enhanced plaque stability in the ApoE ^-/- mice model with advanced atherosclerosis. Taken together, this study demonstrated the potential of HA@PC@Pita NPs for the treatment of advanced atherosclerosis.

The diagnosis of hematological disorders is currently established from the combined results of different tests, including those assessing morphology (M), immunophenotype (I), cytogenetics (C), and molecular biology (M) (collectively known as the MICM classification). In this workflow, most of the results are interpreted manually (i.e., by a human, without automation), which is expertise-dependent, labor-intensive, time-consuming, and with inherent interobserver variability. Also, with advances in instruments and technologies, the data is gaining higher dimensionality and throughput, making additional challenges for manual analysis. Recently, artificial intelligence (AI) has emerged as a promising tool in clinical hematology to ensure timely diagnosis, precise risk stratification, and treatment success. In this review, we summarize the current advances, limitations, and challenges of AI models and raise potential strategies for improving their performance in each sector of the MICM pipeline. Finally, we share perspectives, highlight future directions, and call for extensive interdisciplinary cooperation to perfect AI with wise human-level strategies and promote its integration into the clinical workflow.

Objective:To explore the demographic composition of type 2 diabetes mellitus (T2DM) with metabolic associated fatty liver disease (MAFLD) and the role of energy metabolism in the progression of MAFLD in order to provide theoretical support for improving the prognosis of MAFLD.Methods:A cross-sectional study was conducted. Ninety-four cases with T2DM combined with MAFLD admitted to the Endocrinology Department of Tianjin Third Central Hospital from July 2014 to July 2019 were selected. Patients were divided into three groups: non-metabolic associated steatohepatitis (MASH) group (25 cases), borderline MASH group (49 cases), and MASH group (20 cases) according to the non-alcoholic fatty liver disease activity score (NAS). Patients were further divided into two groups: non/mild fibrosis (F0-1) group (74 cases) and the significant fibrosis (F2-4) group (20 cases) in accordance with liver fibrosis scores. The differences in general clinical and biochemical indicators, body composition, and energy metabolism indicators among the groups were compared. Binary logistic regression analysis was conducted to explore factors affecting liver inflammation and fibrosis severity degree in patients with MAFLD.Results:The visceral fat area (VFA) and body fat percentage (PBF) were significantly higher in the MASH group than in the non-MASH group ( P<0.05), while the skeletal muscle mass index and body mass index (SMI-BMI) were significantly lower in the MASH group than in the marginal MASH group ( P<0.05) during the comparison of body composition and substrate metabolism at different stages of MASH. Alanine aminotransferase (ALT) and homeostasis model assessment of insulin resistance (HOMA-IR) were significantly higher in the fibrotic group than in those in the no/mild fibrosis group ( P<0.05) when comparing clinical and biochemical indicators, body composition, and substrate metabolism at different stages of fibrosis. The skeletal muscle mass (SMM), SMI-BMI, SMM-Weight, resting energy expenditure (REE), and fat oxidation rate (FAT OXR) were significantly lower in the fibrotic group than those in the no/mild fibrosis group ( P<0.05). The respiratory quotient and carbohydrate functional ratio (%CHO) were significantly higher in the fibrotic group than in the no/mild fibrosis group ( P<0.05). Correlation analysis indicated a positive correlation between the NAS score, reflecting the severity of liver inflammatory lesions, with VFA and PBF ( r=0.258 and 0.323, P<0.05); while the F score was positively correlated with the respiratory quotient, %CHO, and VFA ( r=0.292, 0.303, and 0.239, P<0.05), and negatively correlated with REE, the energy ratio from fat, FAT OXR, SMM, SMI-Weight, and SMI-BMI ( r=-0.209, -0.214, -0.333, -0.240, -0.250, and -0.305, P<0.05). Logistic regression analysis indicated that SMI-Weight and FAT OXR were independent factors affecting the progression of liver fibrosis. Conclusion:The reduction of skeletal muscle, particularly because of energy metabolism, is a factor affecting the progression of fibrosis in MAFLD.
