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.

Objective To systematically construct patient-derived tumor organoid(PDO)and patient-derived xenograft(PDX)models of prostate cancer(PCa),and to explore the inhibitory effect and mechanism of gambogic acid(GA)on PCa.Methods The PubChem,SwissTargetPrediction,SuperPred,SEA,GeneCards,OMIM,and STRING databases,and the Venny 2.1.0 online website,Cytoscape 3.8.2,and DAVID software were used to construct a protein-protein interaction network.Gene ontology(GO)and kyoto encyclopedia of genes and genomes(KEGG)enrichment analyses were carried out,and visualization processing was performed to identify the targets and pathways of GA acting on PCa.GA was applied to PDOs and PCa cells(22Rv1,PC3,and DU145)for 48 hours and its effects on cell viability were assessed by CellTiter-Glo and CCK-8 assays.Changes in gene and protein levels of the targets were analyzed by quantitative real-time polymerase chain reaction and Western Blot,respectively.The PDX model was treated with GA and the tumor volume and weight were measured.Changes in expression levels of the targets in tumor tissues were detected by immunohistochemistry.Results Network pharmacology identified signal transducer and activator of transcription 3(STAT3)as the core target of GA inhibiting PCa,related to the hypoxia-inducible factor(HIF)-1α signaling pathway.GA reduced the viability of cells and PDOs and significantly down-regulated HIF-1α,STAT3,and P-STAT3 protein levels.In vivo experiments,tumor volume and weight were significantly reduced in the GA group,and immunohistochemistry showed that STAT3 and HIF-1α expression levels were decreased.Conclusions The clinically representative PDO and PDX models,combined with cell lines,verified the prediction result of network pharmacology,confirming a significant killing effect of GA on PCa,possibly via a mechanism related to the STAT3/HIF-1α signaling pathway.

Objective: To investigate the characteristics of temporal and spatial distribution of tuberculosis epidemics in Shache County, Kashgar Region, Xinjiang. Methods: Information on the incidence of tuberculosis in Sacha County from 2019—2021 was collected and spatiotemporally analyzed by applying the circular distribution method, local spatial autocorrelation analysis, hot and cold spot analysis, directional distribution and spatial center of gravity methods. Results : The total number of tuberculosis cases in Shache County in 2019—2021 was 8 345, of which 52.03%were male and 47.97% were female, and the patients were predominantly 60-75 years old. The number of reported incidences of TB in Tagarqi Township, Shache Township, and Chajek Township ranked among the top three in the county. Spring and summer were the disease-prone seasons for TB, and mid-March to mid-July was the period of high disease incidence. Misha Township and Ishkuli Township are the “high and high” gathering areas, while the “low and low” gathering areas are mainly concentrated in Khoshrav Township and Karasu Township. The hotspots of TB incidence in Shache county were Tagarqi township, Misha township, and Ishkuli township. During the study period, the center of gravity of TB incidence in Shache county of Kashgar area gradually shifted from the southwest to the northeast. Conclusion In Shache county, there is a certain degree of aggregation of tuberculosis outbreaks, with more men than women reporting illnesses, a larger proportion of older people, and a strong seasonal incidence of the disease, with Mixia township and Ishikuli township being the key areas of incidence. Relevant departments should continue to strengthen the disease surveillance of key populations and regions during the high incidence of tuberculosis, and take appropriate intervention measures to reduce the risk of tuberculosis transmission.

Objective To investigate the effect of four traditional Chinese drugs for reinforcing kidney combined with Tongqiao Huoxue Decoction on serum neurotransmitters and neurological func-tion in patients with post-stroke cognitive impairment(PSCI).Methods A total of 110 patients with PSCI were randomly divided into treatment group and control group,with 55 cases in each group.The control group was treated with donepezil tablet,while the treatment group was treated with four tradi-tional Chinese drugs for reinforcing kidney and Tongqiao Huoxue Decoction on the basis of the control group.The total effective rate,the Mini-Mental State Examination(MMSE)score,the Montreal Cogni-tive Assessment(MoCA)score,the National Institutes of Health Stroke Scale(NIHSS)score and the Barthel Index(BI)as well as serum levels of acetylcholine(ACh),dopamine(DA),norepinephrine(NE),5-hydroxytryptamine(5-HT),neuron-specific enolase(NSE),visinin-like protein-1(VILIP-1),myelin basic protein(MBP),and heat shock protein 70(HSP70)before and after treatment were compared between the two groups.Adverse reactions in both groups were recorded.Results The total effective rate was 90.91％in the treatment group,which was significantly higher than 76.36％in the control group(P＜0.05).After treatment,the MMSE score,MoCA score and BI as well as serum levels of ACh,DA,NE,5-HT and HSP70 in the treatment group were significantly higher than those in the control group,while the NIHSS score and serum levels of NSE,VILIP-1 and MBP were significantly lower than those in the control group(P＜0.05).The total incidence rate of adverse reactions in the treatment group and the control group was 12.73％and 9.09％respectively,which showed no significant between-group difference(P＞0.05).Conclusion Four traditional Chinese drugs for reinforcing kidney combined with Tongqiao Huoxue Decoction can promote the secretion of cognition-related neurotransmitters in patients with PSCI,accelerate the repair of neurological damage,and safety is relatively high.

AIM:This study aimed to observe the analgesic effects of Hegu acupoint catgut embedding in a rat model of labor and investigate its influence on biomarkers such as calcitonin gene-related peptide(CGRP)signals at the Hegu acupoint.METHODS:Thirty-six pregnant rats were randomly divided into three groups:control group,Hegu acu-puncture group,and Hegu catgut embedding group.Pain threshold changes were assessed using the tail immersion test and paw withdrawal thermal latency at four time points:pre-induction,before the onset of labor,at the onset of labor,and at the mid-stage of labor.Tissue samples from the Hegu acupoint were collected at the mid-stage of labor to detect the ex-pression of CGRP,substance P(SP),and mast cells using immunofluorescence.The concentrations of ATP and ade-nosine were measured using ELISA.RESULTS:Before labor induction,there was no significant difference in tail immer-sion test and paw withdrawal thermal latency among the three groups(P>0.05).Before the onset of labor,both the acu-puncture and catgut embedding groups exhibited significantly higher tail-flick times and paw withdrawal latencies com-pared to the control group(P<0.05).At labor initiation and mid-labor,the catgut embedding group had significantly higher tail-flick times and paw withdrawal latencies compared to both the control and acupuncture groups(P<0.05).During mid-labor,the expression of CGRP,SP,mast cells,ATP,and adenosine concentrations in the catgut embedding group was significantly higher than that in the control and acupuncture groups(P<0.05),with co-expression of CGRP,SP,and mast cells observed.CONCLUSION:Hegu acupoint catgut embedding effectively alleviates labor pain,and its mechanism may involve increased local expression of CGRP and SP,promoting mast cell degranulation,and increasing ATP release and its conversion to adenosine.

Uric acid (UA), the final product of human purine metabolism, can cause hyperuricemia (HUA) when excessively accumulated. HUA is closely linked to chronic kidney diseases (CKD) and is considered an independent risk factor. Hyperuricemic nephropathy, a form of CKD induced by HUA, has seen significant advances in understanding through research into the pathogenic roles of uric acid and the development of HUA animal models. Although progress has been made in understanding the pathophysiological mechanisms by which UA induces CKD, much remains to be learned about its pathological molecular mechanisms. New approaches in animal modeling or the selection of model animals may potentially lead to significant breakthroughs in research on hyperuricemia as well as related CKD. This paper reviews the research progress on the molecular mechanisms of hyperuricemic nephropathy, focusing on oxidative stress, inflammation, autophagy, fibrosis, and gut microbiota. Oxidative stress is induced by uric acid intracellularly through xanthine oxidase, NADPH oxidases, and mitochondria, leading to cellular damage. In terms of inflammation, uric acid crystals can activate the NLRP3 inflammasome, triggering an inflammatory cascade. The role of free uric acid as a pro-inflammatory agent, however, remains controversial. Depending on the study conducted, autophagy has been found to either alleviate or exacerbate inflammation induced by uric acid. Fibrosis, particularly through epithelial-mesenchymal transition (EMT), is a major mechanism by which uric acid causes glomerulosclerosis and tubulointerstitial fibrosis. Extensive research has explored various signaling pathways involved in uric acid-induced EMT. Beneficial gut microbiota protect the kidneys by synthesizing short-chain fatty acids, reducing urea’s enterohepatic circulation, and decreasing uric acid production. This paper aims to enhance understanding of the complex relationships between HUA and CKD, serving as a reference for further research and new drug development.
