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 analyze the etiological characteristics and risk factors of autosomal dominant polycystic kidney disease （ADPKD） complicated with urinary tract infection （UTI）. MethodsA retrospective analysis was performed on 244 patients with ADPKD admitted to the Department of Nephrology. The patients were stratified into a study group （n=138） and a control group （n=106） according to the presence or absence of concurrent UTI. All patients in the study group underwent etiological testing and drug susceptibility testing. Clinical data of both groups were collected to identify the risk factors for ADPKD complicated with UTI. ResultsA total of 105 pathogens were detected in 138 cases in the study group， including 79 Gram-negative bacteria， 20 Gram-positive bacteria and 6 fungi. Escherichia coli showed a relatively high resistance rate to ampicillin， piperacillin and ciprofloxacin. Enterococcus faecalis had a relatively high resistance rate to tetracycline. There were statistically significant differences between the study group and the control group in terms of gender， history of urinary tract infection， C-reactive protein （CRP）， increased urine red blood cells， increased urine white blood cells， increased percentage of neutrophils， blood sodium， blood calcium， total cholesterol， serum iron and transferrin saturation （P<0.05）. Multivariate binary Logistic regression analysis revealed that female gender （OR=2.236， P=0.004）， history of urinary tract infection （OR=2.383， P=0.002）， increased urine white blood cells （OR=2.726， P=0.001）， increased percentage of neutrophils （OR=1.040， P=0.010）， elevated C-reactive protein （OR=1.011， P=0.007） and elevated blood calcium （OR=4.389， P=0.024） were risk factors of urinary tract infection in ADPKD patients （P<0.05）. ConclusionThe main pathogens of UTI in patients with ADPKD are Gram-negative bacteria. Female， previous history of urinary tract infection， urinary leukocytosis， increased percentage of neutrophils， increased CRP and increased serum calcium are risk factors of UTI.

Depression is a common psychiatric disorder characterized by persistent low mood or mental disorders. Current treatments primarily focus on regulating neurotransmitter levels， but their effectiveness is limited. The mechanisms underlying its onset are complex， and there is no unified consensus. Abnormal signaling pathway transmission plays a crucial role in the development of depression， involving multiple pathways， including Toll-like receptor 4/nucleotide-binding oligomerization domain-like receptor protein 3 （TLR4/NLRP3）， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， mitogen-activated protein kinase/extracellular signal-regulated kinase （MAPK/ERK）， brain-derived neurotrophic factor/tyrosine kinase receptor B （BDNF/TrkB）， cyclic AMP/protein kinase A/cAMP response element-binding protein （cAMP/PKA/CREB）， and others. Traditional Chinese medicine（TCM） is based on a holistic approach and the principle of treatment based on the differentiation of syndromes， regulating the balance of multiple systems and organ functions from a macroscopic perspective. This approach has shown unique advantages in the treatment of depression. TCM attributes the onset of depression to dysfunction of the organ systems， involving liver Qi stagnation， heart spirit deficiency， kidney essence depletion， and spleen dysfunction. TCM compound treatments focus on soothing the liver， strengthening the spleen， calming the heart， and replenishing essence， with formulas such as Xiaoyaosan， Zishui Qinggan Yin， and Chahu Jia Guizhi Longgu Muli Tang. The active components of Chinese herbs mainly aim to tonify and regulate Qi， such as salidroside， ginsenoside Rb₁， astragaloside， and muscone. External TCM treatments， primarily acupuncture， aim to open the orifices and invigorate the spirit. Acupoints such as Baihui， Shenting， and Yintang are commonly used. Additionally， massage and moxibustion therapy can intervene in depression by regulating signaling pathways. This article reviews the core role of signaling pathways in the development of depression and the mechanism of TCM regulation of signaling pathways to intervene in depression， aiming to discover new therapeutic approaches that can improve the symptoms of depressed patients.

Geraniin, a polyphenol derived from the fruit peel of Nephelium lappaceum L., has been shown to possess anti-inflammatory and antioxidant properties in the cardiovascular system. The present study explored whether geraniin could protect against an isoproterenol (ISO)-induced cardiac hypertrophy model. Mice in the ISO group received an intraperitoneal injection of ISO (5 mg/kg) once daily for 9 days, and the administration group were injected with ISO after 5 days of treatment with geraniin or spironolactone. Potential therapeutic effects and related mechanisms analysed by anatomical coefficients, histopathology, blood biochemical indices, reverse transcription-PCR and immunoblotting. Geraniin decreased the cardiac pathologic remodeling and myocardial fibrosis induced by ISO, as evidenced by the modifications to anatomical coefficients, as well as the reduction in collagen I/III á1mRNA and protein expression and cross-sectional area in hypertrophic cardiac tissue. In addition, geraniin treatment reduced ISO-induced increase in the mRNA and protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α, whereas ISO-induced IL-10 showed the opposite behaviour in hypertrophic cardiac tissue.Further analysis showed that geraniin partially reversed the ISO-induced increase in malondialdehyde and nitric oxide, and the ISO-induced decrease in glutathione, superoxide dismutase and glutathione. Furthermore, it suppressed the ISO-induced cellular apoptosis of hypertrophic cardiac tissue, as evidenced by the decrease in Bcell lymphoma-2 (Bcl-2)-associated X/caspase-3/caspase-9 expression, increase in Bcl-2 expression, and decrease in TdT-mediated dUTP nick-end labeling-positive cells.These findings suggest that geraniin can attenuate ISO-induced cardiac hypertrophy by inhibiting inflammation, oxidative stress and cellular apoptosis.

Objective:To explore the effects of ubiquitin-conjugating enzyme E2L3 (UBE2L3) on the proliferation and apoptosis of head and neck squamous cell carcinoma (HNSCC) cell line UMSCC-1 in vitro and its potential mechanisms, and to investigate the relationship between UBE2L3 and immune cell infiltration in the HNSCC tumor microenvironment.Methods:The plasmid carrying UBE2L3 gene sequence was transfected into UMSCC-1 cells by using liposome transfection technology (UBE2L3 overexpression group), and UMSCC-1 cells transfected with the empty plasmid was treated as the control group. The quantitative polymerase chain reaction (qPCR) was used to detect the expression level of UBE2L3 mRNA after transfection, and the transfection efficiency was evaluated. The proliferation levels of the 2 groups of cells were detected by using CCK-8 assay and the cell proliferation rate was calculated. The apoptosis rates of the 2 groups of cells after etoposide induced apoptosis for 24 h were detected by using flow cytometry. The expression levels of Cyclin D1, apoptosis-related proteins bcl-2, and Bax in the 2 groups of cells were detected by using Western blotting. The samples of 504 HNSCC tissues in the Cancer Genome Atlas (TCGA) were analyzed by using the single-sample gene set enrichment analysis (ssGSEA) database. The median expression level of UBE2L3 was used to distinguish between high and low expression of UBE2L3 transcriptional level. The differences in immune cell enrichment score between high and low expression samples were compared, and the relationship between UBE2L3 expression level and immune cell number was analyzed.Results:qPCR results showed that the relative expression level of UBE2L3 mRNA in UMSCC-1 cells carrying UBE2L3 gene sequence plasmid was higher than that in UMSCC-1 cells transfected with the empty plasmid (9.32±1.15 vs. 1.00±0.02), and the difference was statistically significant ( t = 7.23, P < 0.001), indicating successful transfection. The CCK-8 assay showed that the cell proliferation rate of UMSCC-1 cells in the UBE2L3 overexpression group for 24 h and 48 h of culture was higher than that in the control group [24 h: (184.0±7.9)% vs. (100.0±5.6)%; 48 h: (165.5±5.3)% vs. (100.0±5.3)%], and the differences were statistically significant (both P < 0.001). Flow cytometry showed that the apoptosis rate of UMSCC-1 cells in the UBE2L3 overexpression group was lower than that in the control group [(9.9±1.3)% vs. (15.6±1.3)%], and the difference was statistically significant ( t = 2.78, P = 0.005). Western blotting showed that the relative expression levels of Cyclin D1 and bcl-2 proteins in UMSCC-1 cells of the UBE2L3 overexpression group were higher than those in the control group, while the relative expression level of Bax protein was lower than that in the control group, and the differences were statistically significant (all P < 0.05). The ssGSEA analysis showed that the enrichment scores of B cells, CD8 + T cells, neutrophils, T cells, T helper 17 (Th17) cells, and regulatory T cells (Treg) in 252 HNSCC tissues samples with low UBE2L3 transcriptional expression level were higher than in 252 samples with high UBE2L3 transcriptional expression level in the TCGA database, while the enrichment scores of natural killer (NK) cells and T helper 2 (Th2) cells in patients with low UBE2L3 expression were lower than those in those with high UBE2L3 expression, and the differences were statistically significant (all P < 0.05). Correlation analysis showed that the expression level of UBE2L3 in HNSCC tissues was positively correlated with the number of Th2 cells ( R = 0.182) and NK cells ( R = 0.172), and negatively correlated with the number of Treg cells ( R = -0.095), dendritic cells ( R = -0.099), Th17 cells ( R = -0.129), CD8 + T cells ( R = -0.146), mast cells ( R = -0.161), T cells ( R = -0.171), and B cells ( R = -0.188), and the differences were statistically significant (all P > 0.05). Conclusions:UBE2L3 can promote the proliferation and inhibit the apoptosis of HNSCC cells probably by regulating the cell cycle and apoptosis signaling pathways through Cyclin D1, bcl-2, and Bax. UBE2L3 may be associated with immune cell infiltration in the HNSCC microenvironment.

Objective:To analyze the epidemiologic characteristics of avian influenza virus and the molecular characteristics and genetic evolution of H9N2 subtype avian influenza viruses in the live poultry markets in Fujian province in 2021-2023.Methods:Six types of specimens were collected from five cities in Fujian province. The specimens were subjected to nucleic acid detection for influenza A viruses, subtypes H5, H7, and H9 by fluorescence quantitative PCR, and the results were analyzed statistically with χ2 test. Specimens with Ct value less than 31 were screened for targeted amplification and next-generation sequencing of the hemagglutinin (HA) and neuraminidase (NA) genes. Reference sequences were downloaded from the databases, and the characteristics of molecular variation and genetic evolution were analyzed by using bioinformatics softwares. Results:From 2021 to 2023, a total of 1 853 specimens were collected from five cities, with a positive rate of 50.94% for influenza A viruses, including 684 specimens of H9 subtype, 23 specimens of H5 subtype, 1 specimen of H7 subtype, 28 specimens of H5 and H9 subtype, 1 specimen of H7 and H9 subtype, and 207 specimens of unclassified A-type. There were significant differences in the positive detection rates of influenza A viruses in different cities( χ2=461.82, P<0.001). Statistically significant differences in influenza A virus positivity rates across years and quarters( χ2=12.26, P=0.002; χ2=30.12, P<0.001), with higher rates of 56.39% and 55.34% in the first and third quarters, respectively. And the differences in the positive rates of influenza A viruses in different types of specimens were statistically significant( χ2=23.05, P<0.001), with specimens on the cage surface having a positivity rate of 56.09%, which was the highest of all types of specimens. A total of 24 strains of HA and NA genes of H9N2 subtype were fully sequenced. Compared with the sequence of NCBI database, the highest identity of HA gene nucleotide sequences ranged from 97.03% to 99.87%, and the highest identity of NA gene nucleotide sequences ranged from 97.50% to 99.78%.Twenty-three strains with both HA and NA genes belonged to the G57 genotype in the Y280-like evolutionary branch of the Eurasian lineage, and one strain belonged to the Y439-like evolutionary branch of the Eurasian lineage. The cleavage sites of all the strains showed the characteristic of low pathogenicity, and most strains had receptor binding sites characterized by avian-derived and human receptors. Conclusions:The overall positive rate of avian influenza viruses in live poultry markets in Fujian province was relatively high, especially in the first and third quarters, with H9 subtype accounting for the main proportion. Most of H9N2 subtype belonged to the Y280-like G57 genotype with a small number of Y439-like evolutionary branches, suggesting the possibility of genetic recombination and the risk of human infection. Thus, surveillance of avian influenza viruses in the live poultry markets as well as mutation analysis should continue to be strengthened.
