Spinal epidural hemorrhages (SEDH) caused by spinal epidural arteriovenous fistulas (SEAVFs) are rare; thus, their specific pathogenesis has not been explained. Furthermore, the standard treatment for SEAVFs has not yet been defined. Here we report the case of a 36-year-old Chinese man who experienced acute onset chest pain and tightness. His symptoms rapidly aggravated until the lower limbs were unable to support him. Spinal magnetic resonance angiography (MRA) revealed a localized SEAVF and a secondary spinal cord lesion at the T4 level. Digital subtraction angiography (DSA) confirmed the presence of the SEDH/SEAVF at the T3–4 level with the left radicular artery feeding the fistula. Based on DSA and MRA findings, SEDH, local spinal cord infarction, and spinal venous reflux disorder were conditionally diagnosed. Using the arterial route, Onyx-34 was injected into the fistula to embolize the feeding arteries and the venous system. Angiography was performed after the microcatheter was withdrawn, and no residual fistula or anterior spinal artery was observed. The six-week follow-up MRI showed acceptable healing of the SEAVF, and the patient improved neurologically. This case suggests that endovascular treatment with Onyx-34 embolization should be considered a promising treatment strategy for this type of complicated SEAVF. 相似文献

目的 探讨C反应蛋白与白蛋白比值(CRP/ALB)对川崎病(KD)早期丙种球蛋白(IVIG)抵抗的预测价值。方法 将2020年1月至2023年6月成都医学院第一附属医院住院的118例病程≤5 d的KD患儿分为IVIG抵抗组和IVIG敏感组,分析患儿临床资料,采用多因素Logistic回归分析探究独立危险因素,ROC曲线探究CRP/ALB对KD患儿早期IVIG抵抗的预测价值。结果 IVIG抵抗组比IVIG敏感组有更高水平的白细胞计数(WBC)、CRP、CRP/ALB和更低水平的血红蛋白(HGB)。CRP/ALB升高和HGB降低是KD患儿早期IVIG抵抗的独立危险因素。CRP/ALB可预测KD患儿早期IVIG抵抗(AUC=0.664)。结论 CRP/ALB升高和HGB降低是KD患儿早期IVIG抵抗的独立危险因素,CRP/ALB可有效预测KD患儿早期IVIG抵抗。 相似文献

目的 采用两样本孟德尔随机化研究,探索血脂水平和子宫内膜异位症之间的因果关系。方法 利用大样本全基因组关联研究(GWAS)汇总数据,选择与各类血脂水平密切相关的遗传位点为工具变量,采用逆方差加权法进行两样本孟德尔随机化分析,以OR值评价各类血脂水平与子宫内膜异位症间的因果关系。结果 除了极小极低密度脂蛋白(VLDL)胆固醇外,其余与VLDL有关的血脂水平升高会增加子宫内膜异位症的发病风险(OR>1)。高密度脂蛋白(HDL)中与胆固醇有关的血脂类型、小低密度脂蛋白(LDL)中总胆固醇水平升高可减少子宫内膜异位症的发病风险(OR<1)。所有与甘油三酯相关的血脂类型、小LDL中胆固醇酯与总脂质比率的升高均可增加子宫内膜异位症的发病风险(OR>1)。结论 多种类型的血脂水平会影响子宫内膜异位症的发生,HDL中与胆固醇或甘油三酯相关的血脂水平可作筛查子宫内膜异位症的生物指标。 相似文献

Lignin, one of the main components of lignocellulose, can be used as an alternative to chemical polyols in the production of polyurethane because of its abundant phenolic and alcohol hydroxyls. Traditionally, lignin is directly applied in the preparation of polyurethane; however, modified lignin has been proved to be superior, especially that obtained by the oxypropylation reaction. Therefore, lignopolyol obtained by mild and efficient oxypropylation was utilized in the production of rigid polyurethane foam in this study. Specifically, the effects of the content of lignopolyol on the chemical structure, morphological structure, mechanical properties and thermal stability of the lignin-based rigid polyurethane foam were investigated. It was found that the compressive strength of the rigid polyurethane foam was significantly improved with the addition of lignopolyol compared with that of the pure polyurethane foam, which was attributed to the fact that oxypropylation made lignin into highly branched and functionalized polyols by transforming all phenolic hydroxyls into aliphatic hydroxyls. Moreover, when the molal weight of lignopolyol accounted for 40% of the added polyols, the generated foam showed optimal uniformity and regularity, and the compressive strength reached 0.18 MPa, meeting the requirements of industrial application, below which, the amount of undesired reactions is bound to increase. As a consequence, the added amount of lignopolyol was increased as much as possible on the basis of guaranteeing the desired properties, which was more conducive to realizing the green degradation and economic synthesis of rigid polyurethane foam.Lignin-based polyurethane foam with excellent performance could be produced with the lignopolyol prepared by mild and efficient oxypropylation. 相似文献

The study aimed to evaluate the clinical significance of thyroid hormone-responsive (THRSP) and explore its relevant pathways in thyroid carcinoma (THCA).The gene expression data of THRSP were obtained and the prognostic significance of THRSP in THCA was analyzed through various bioinformatics databases. Then, the factors influencing THRSP mRNA expression were explored, and the function of THRSP in predicting the lymph node metastasis (LNM) stage was determined. We further performed the enrichment analysis and constructed a protein–protein interaction (PPI) network to examine potential regulatory pathways associated with THRSP.THRSP gene expression was significantly increased in THCA compared with the normal tissues. High THRSP mRNA expression had a favorable overall survival (OS) in THCA patients (P < .05). Additionally, the mRNA expression of THRSP was related to stage, histological subtype, and methylation among THCA patients (all P < .05). Besides, THRSP served as a potent predictor in discriminating the LNM stage of thyroid cancer patients. According to Kyoto Encyclopedia of Genes and Genomes (KEGG) and gene set enrichment analysis (GSEA) on THRSP-associated genes, THRSP was positively related to metabolic pathways.The upregulation of THRSP predicted a good OS in THCA patients. Furthermore, THRSP might inhibit THCA progression through positive regulation of metabolism-associated pathways. 相似文献

Background:This study retrospectively investigated the effects of target nursing care (TNC) on anxiety and depression in patients with gallbladder cancer (GBC) during the perioperative period.Methods:This retrospective study analyzed the data of 80 patients with GBC during perioperative period. These records were divided into an intervention group (n = 40) or a control group (n = 40). All 80 patient records in both groups were administered routine nursing care (RNC). The patients in the intervention group also underwent TNC. The primary outcomes were depression (measured using the Hamilton Depression Scale, HAMD) and anxiety (assessed using the Hamilton Anxiety Scale, HAMA). The secondary outcomes were quality of life (assessed using the 36-Item Short Form Health Survey, SF-36) and adverse events. We collected and analyzed the outcome data before and after treatment.Results:After treatment, patients in the intervention group showed more promising effects on depression (HAMD, P < .01) and anxiety (HAMA, P < .01) than those in the control group did. However, there were no significant differences in the quality of life before and after treatment. No TNC- or RNC-associated adverse events were reported in patient records.Conclusion:This study found that TNC was more effective than RNC in relieving depression and anxiety. Future studies should be conducted to validate the present findings. 相似文献
