目的 探索α-突触核蛋白(α-Syn)干预对人单核细胞白血病细胞系(THP-1)巨噬细胞源性泡沫细胞的影响。方法 通过佛波酯(PMA)和氧化型低密度脂蛋白(ox-LDL)构建THP-1巨噬细胞源性泡沫细胞模型,使用不同浓度(33、66、100、133 nmol/L)α-Syn处理泡沫细胞,随后检测细胞胆固醇含量和炎症因子白细胞介素-1β(IL-1β)、白细胞介素-6(IL-6)及白细胞介素-8(IL-8)的mRNA表达以及核因子κB(NF-κB)和凝集素样氧化低密度脂蛋白受体-1(LOX-1)的蛋白表达变化。结果 高剂量(100和133 nmol/L)α-Syn处理可以减少THP-1巨噬细胞源性泡沫细胞内胆固醇的含量(P<0.05),并且减少IL-1β、IL-6和IL-8的mRNA表达(P<0.05)。进一步发现(100 nmol/L和133 nmol/L)α-Syn可以降低THP-1巨噬细胞源性泡沫细胞p-NF-κB和LOX-1的蛋白表达(P<0.05)。结论 α-Syn可以降低THP-1源性巨噬细胞泡沫细胞胆固醇蓄积和炎症反应,可能是通过下调p-NF-κB和LOX-1蛋白表达。
Objective To explore the effects of α-synuclein(α-Syn)intervention on human monocytic leukemia cell(THP-1)macrophage-derived foam cells.Methods The THP-1 macrophage-derived foam cell model was constructed by phorbol 12-myristate 13-acetate(PMA)and oxidized low-density lipoprotein(ox-LDL).Foam cells were treated with different concentrations(33, 66, 100, and 133 nmol/L)of α-Syn, and the cellular cholesterol contents, as well as the mRNA expression of IL-1β、IL-6 and IL-8 were detected.Subsequently,alternation in protein expression of NF-κB and LOX-1 was measured.Results High-dose(100 and 133nmol/L)α-Syn treatment significantly reduced the levels of intracellular cholesterol in THP-1-derived macrophage foam cells(P<0.05)and decreased the mRNA expression of IL-1β、IL-6 and IL-8(P<0.05).It was further found that(100 nmol/L and 133 nmol/L)α-Syn decreased the protein expression of p-NF-κB and LOX-1 in THP-1 macrophage-derived foam cells(P<0.05).Conclusions The results of the present study suggest that α-Syn reduces cholesterol accumulation and inflammatory response in THP-1-derived macrophage foam cells, possibly by down-regulating p-NF-κB and LOX-1 protein expression.

Objective To explore the risk factors and to construct a nomogram prediction model for severe macrolide-resistant Mycoplasma pneumoniae pneumonia(MPP)in children.Methods The clinical data during the initial admission period of 1 121 children with macrolide-resistant MPP who were hospitalized in the Department of Pediatrics of the Affiliated Panyu Central Hospital of Guangzhou Medical University from January 2023 to September 2024 were retrospectively collected.The children data were randomly divided into a training set(n=784)and a validation set(n=337)at a ratio of 7∶3.With R language software(version 4.4.1), least absolute shrinkage and selection operator(LASSO)regression analysis with tenfold cross-validation was used to screen risk factors, Logistics regression analysis was used to establish prediction model, and a visualization of the risk variables was created using a nomogram.The receiver operating characteristic(ROC)curves, calibration curves, Hosmer-Lemeshow(HL)test and clinical decision curve analysis(DCA)were used to evaluate the discrimination, calibration and clinical application value of the model.Results In the training set, LASSO regression analysis combined with Logistics regression analysis showed that prehospital fever duration > 5.5 days, alanine aminotransferase level> 14.5 U/L, lactate dehydrogenase level> 287.5 U/L, C-reactive protein > 18.65 mg/L, lung consolidation, and co-infection with virus were risk factors for severe macrolide-resistant MPP(P<0.05).A nomogram prediction model was constructed based on the above risk factors.The area under the ROC curves of the training set and the validation set were 0.847 and 0.822, respectively.The calibration curves and HL test showed that the model had good calibration. The DCA curves showed that the prediction model had the best prediction performance when the risk threshold was between 0.05-0.95.Conclusions Prehospital fever duration, alanine aminotransferase level, lactate dehydrogenase level, C-reactive protein level, lung consolidation and co-infection with virus were risk factors for prediction of severe macrolide-resistant MPP.The nomogram model based on the above factors had a good prediction efficiency, which was conducive to early identification of severe cases with macrolide-resistant, and taking early effective interventions to improve the prognosis.

泛血管疾病(PVD)是一类以动脉粥样硬化为共同病理基础、累及心、脑、肾及外周血管系统的临床综合征, 具有多血管床共病特征, 发病率高、致残致死率大。非编码RNA(ncRNA)作为基因表达的重要调控因子, 在PVD的发生发展中发挥关键作用。微小RNA(miRNA)、长链非编码RNA(lncRNA)、环状RNA(circRNA)等ncRNA通过调节炎症反应、内皮功能、血管重塑、代谢稳态等多路径参与PVD的病理过程, 并展现出时空特异性和双向调控特征。最新研究揭示ncRNA在临床中的诊断预测及靶向干预潜力, 包括外泌体载体及circRNA递送系统等新策略。此外, 中医药通过调控ncRNA网络, 干预血瘀、痰浊等证型相关通路, 体现中西医结合治疗的系统优势。本文系统综述了ncRNA在PVD中的作用机制与研究进展, 强调其在精准诊疗与转化研究中的应用前景, 并指出未来需加强基础与临床协同、推进个体化干预策略的落地实施。
Panvascular diseases(PVD)are a group of clinical syndromes characterized by atherosclerosis as a common pathological foundation, involving heart,brain,kidneys,and peripheral vascular systems.These diseases often exhibit multi-vascular bed comorbidities and are associated with high incidence,disability, and mortality rates.Non-coding RNAs(ncRNAs), as key regulators of gene expression, play a crucial role in the onset and progression of PVD.Various types of ncRNAs—including microRNAs(miRNAs), long non-coding RNAs(lncRNAs), and circular RNAs(circRNAs)—are involved in the pathological processes of PVD through multiple pathways, such as modulation of inflammatory responses, endothelial function, vascular remodeling, and metabolic homeostasis, exhibiting spatiotemporal specificity and bidirectional regulatory effects.Recent studies have highlighted the potential of ncRNAs in clinical diagnosis, prognosis, and targeted therapy,with novel strategies including exosome-based delivery and circRNA-targeting systems.In addition, traditional Chinese medicine(TCM)exerts regulatory effects on ncRNA networks to intervene in syndrome-specific pathways, such as those related to blood stasis and phlegm-dampness, reflecting the systemic advantages of integrating TCM with Western medicine.This review systematically summarizes the regulatory mechanisms and research progress of ncRNAs in PVD,emphasizes their potential in precision medicine and translational research, and proposes the need to strengthen collaboration between basic and clinical studies to facilitate the implementation of personalized therapeutic strategies.

Objective To explore the diagnostic value of clinical features combined with peripheral blood vascular endothelial growth factor(VEGF)and α-hydroxybutyrate dehydrogenase(α-HBDH)levels in ovarian cancer.Methods A total of 84 patients with malignant ovarian cancer admitted to the gynecology department of Tianjin Central Hospital of Gynecology and Obstetrics from June 2022 to June 2024 were included in the observation group,and 84 patients with benign ovarian lesions during the same period were included in the control group.The clinical data and VEGF,α-HBDH levels of the two groups were compared.Pearson analysis was used to explore the correlation between VEGF,α-HBDH levels,and clinical characteristics of patients with malignant ovarian cancer.Binary Logistic regression analysis was conducted to identify independent risk factors for malignant ovarian cancer,and receiver operating characteristic(ROC) curves were used to analyze the diagnostic value of VEGF and α-HBDH levels for malignant ovarian cancer.Results The observation group had significantly higher age,BMI,and serum CA125,HE4,VEGF,α-HBDH levels compared to the control group(P<0.05).VEGF and α-HBDH levels were significantly positively correlated with FIGO stage,differentiation grade,and lymph node metastasis(P<0.05).Age,BMI,VEGF,and α-HBDH were included as independent variables in binary Logistic regression,and the results showed that BMI,VEGF,and α-HBDH levelswere independent risk factors for malignant ovarian cancer(P<0.05).ROC curve analysis revealed that the AUC for combined detection of VEGF and α-HBDH reached 0.921,with sensitivity and specificity of 81.0% and 91.7%,respectively,significantly superior to individual detection(VEGF:AUC=0.702;α-HBDH:AUC=0.796).Conclusions The detection of BMI combined with VEGF and α-HBDH levels can provide an efficient and noninvasive auxiliary means for the diagnosis of ovarian cancer,which has important clinical application potential.
