acute cerebral infarction

急性脑梗死
  • 文章类型: Case Reports
    肾性贫血通常是由于肾功能不全导致肾脏促红细胞生成素的产生减少引起的,这可能与死亡率和心血管事件的增加以及诸如疲劳和摇摆等主观症状有关。我们报道了一个87岁的2型糖尿病患者,高血压,和因糖尿病肾病引起的肾性贫血而接受过罗沙司他(一种缺氧诱导因子(HIF)脯氨酸酰羟化酶(PH)抑制剂)治疗的血脂异常,并且由于中枢甲状腺功能减退症的发作,罗沙司改用了达普司他(另一种HIF-PH抑制剂)。大约三周后,患者出现急性无症状性脑梗死,血红蛋白(Hb)升高.目前尚不清楚daprodustat的变化是否与脑梗死的发作有关。然而,这种情况表明,从一种HIF-PH抑制剂改为另一种后,Hb意外急性升高应特别小心,尤其是心血管事件高危患者。
    Renal anemia is generally caused by a decrease in the production of erythropoietin in kidney due to renal dysfunction, and this may be associated with the increase in mortality and cardiovascular events in addition to subjective symptoms such as fatigue and wobbliness. We report a case of an 87-year-old man with type 2 diabetes, hypertension, and dyslipidemia who had received roxadustat (a hypoxia-inducible factor (HIF) prolyl hydroxylase (PH) inhibitor) for renal anemia due to diabetic nephropathy and in whom roxadustat was switched to daprodustat (another HIF-PH inhibitor) due to the onset of central hypothyroidism. About three weeks after this change, the patient developed acute asymptomatic cerebral infarction with an elevation of hemoglobin (Hb). It is unclear if the change to daprodustat was involved in the onset of cerebral infarction. However, this case suggests that particular caution should be paid to unexpected acute elevation of Hb after a change from one HIF-PH inhibitor to another, especially in a patient at high risk for cardiovascular events.

    急性脑梗死(ACI)是一种致死性疾病,其早期诊断对治疗至关重要。微小RNA(miR)-19a靶向心肌梗死中的CC趋化因子配体20(CCL20)。我们研究了ACI患者血清miR-19a和CCL20的表达模式,并评估了其临床价值。收集50例健康受试者和110例ACI患者的血清样本。血清miR-19a水平,CCL20mRNA,并对生化指标进行评估。对miR-19a下游靶基因及miR-19a与CCL20的结合关系进行预测和验证。对miR-19a和CCL20mRNA进行相关性和诊断效率分析。miR-19a在ACI患者血清中低表达,尤其是不稳定斑块和大面积梗死的患者。肿瘤坏死因子-α,低密度脂蛋白,血小板/淋巴细胞比值与血清miR-19a水平呈负相关,与CCL20呈正相关。双荧光素酶检测显示miR-19a可以负调控CCL20的表达。CCL20在ACI患者血清中高表达。miR-19a联合CCL20的受试者工作特征曲线下面积为0.9741(98.00%特异性,90.91%灵敏度),高于其单一诊断。总的来说,miR-19a对ACI有较高的诊断价值,可以靶向克制CCL20。miR-19a和CCL20的组合提高了对ACI的诊断价值。
    Acute cerebral infarction (ACI) is a lethal disease whose early diagnosis is critical for treatment. microRNA (miR)-19a targets CC chemokine ligand 20 (CCL20) in myocardial infarction. We investigated the expression patterns of serum miR-19a and CCL20 of ACI patients and assessed their clinical values. Serum samples of 50 healthy subjects and110 ACI patients were collected. Serum levels of miR-19a, CCL20 mRNA, and biochemical indexes were assessed. miR-19a downstream target gene and the binding relationship between miR-19a and CCL20 were predicted and verified. miR-19a and CCL20 mRNA were subjected to correlation and diagnostic efficiency analysis. miR-19a was poorly expressed in the serum of ACI patients, especially in patients with unstable plaque and large infarction. tumor necrosis factor-α, low-density lipoprotein, and platelet/lymphocyte ratio negatively correlated with serum miR-19a level and positively correlated with CCL20. Dual-luciferase assay revealed that miR-19a could negatively regulate CCL20 expression. CCL20 was highly expressed in the serum of ACI patients. The area under receiver-operating characteristic curve of miR-19a combined with CCL20 was 0.9741 (98.00% specificity, 90.91% sensitivity), higher than their single diagnosis. Collectively, miR-19a had high diagnostic value for ACI and could target to restrain CCL20. The combination of miR-19a and CCL20 improved diagnostic value for ACI.

    中性粒细胞计数升高和白蛋白水平降低与急性脑梗死(ACI)的不良预后有关。这项研究的目的是探讨静脉溶栓(IVT)后ACI患者的中性粒细胞与白蛋白比率(NAR)与早期神经系统改善(ENI)之间的相关性。纳入在2019年6月至2023年6月期间接受IVT的ACI患者。使用美国国立卫生研究院卒中量表(NIHSS)评估ACI的严重程度。ENI定义为IVT后24小时内NIHSS评分降低≥4或神经功能缺损完全缓解。采用倾向评分匹配(PSM)和logistic回归分析,探讨这些变量与患者早期神经系统预后的相关性。共纳入545例ACI患者,有253人(46.4%)经历了ENI。在193对PSM后的患者中,NAR和ENI(或,0.89;95%CI,0.85-0.94;p<0.001)。受限三次样条分析揭示了NAR和ENI之间的显着非线性相关性(非线性p=0.0004;总体p=0.0002)。预测ENI的最佳截止值确定为NAR水平为10.20,敏感性和特异性值为73.6%和60.9%。IVT后ACI患者的NAR水平与ENI相关。NAR水平的降低表明ACI患者溶栓后ENI的可能性增加。
    Elevated neutrophil counts and decreased albumin levels have been linked to an unfavorable prognosis in acute cerebral infarction (ACI). The objective of this study is to explore the correlation between the neutrophil-to-albumin ratio (NAR) and the early neurological improvement (ENI) of ACI patients following intravenous thrombolysis (IVT). ACI patients who underwent IVT between June 2019 and June 2023 were enrolled. The severity of ACI was assessed using the National Institutes of Health Stroke Scale (NIHSS). ENI was defined as a reduction in NIHSS score of ≥ 4 or complete resolution of neurological deficit within 24 h after IVT. Propensity score match (PSM) and logistic regression analysis were used to explore the correlation between these variables and the early neurological outcomes of patients. A total of 545 ACI patients were included, with 253 (46.4 %) experiencing ENI. Among the 193 pairs of patients after PSM, there was a significant association between NAR and ENI (OR, 0.89; 95 % CI, 0.85-0.94; p < 0.001). The restricted cubic splines analysis revealed a significant nonlinear correlation between NAR and ENI (p for nonlinear = 0.0004; p for overall = 0.0002). The optimal cutoff for predicting ENI was determined as a NAR level of 10.20, with sensitivity and specificity values of 73.6 % and 60.9 %. NAR levels are associated with ENI in ACI patients after IVT. The decreased levels of NAR indicate an increased likelihood of post-thrombolysis ENI in ACI patients.

    本文旨在探讨旭明汤在证方记录中的作用,古代和现代关于急性脑梗死大鼠模型脑缺血损伤和血管生成的研究。SD大鼠随机分为6组:假手术组,模型组,低,medium-,高剂量(5.13、10.26和20.52g·kg~(-1),分别)徐明汤组,和丁苯酞(0.06g·kg~(-1))组。经大脑中动脉闭塞(MCAO)成功建立大鼠模型后,假手术组和模型组大鼠分别给予蒸馏水和其他组大鼠相应的药物,连续7天。神经功能评分后,所有的老鼠都被处死了,并收集脑组织样本。通过神经功能缺损评分和氯化2,3,5-三苯基四唑染色评估脑缺血损伤的程度。进行苏木精-伊红染色以观察脑的病理变化。透射电镜观察缺血侧脑组织神经元和微血管内皮细胞(ECs)的超微结构。免疫荧光法检测缺血脑组织中血管性血友病因子(vWF)和造血祖细胞抗原CD34(CD34)的表达。采用实时PCR和Westernblot检测mRNA和蛋白水平,分别,Runt相关转录因子1(RUNX1),血管内皮生长因子(VEGF),血管生成素-1(Ang-1),血管生成素-2(Ang-2),和缺血脑组织中的VEGF受体2(VEGFR2)。结果显示,与假手术组相比,模型组神经功能缺损评分和脑梗死面积增加(P<0.01),病理变化,缺血脑组织中神经元和微血管ECs的超微结构受损。此外,模型上调了RUNX1、VEGF、Ang-1,Ang-2和VEGFR2(P&lt;0.01)以及vWF的蛋白质水平,CD34,RUNX1,VEGF,Ang-1、Ang-2和VEGFR2(P<0.05或P<0.01)。与模型组相比,大剂量旭明汤和丁苯酞可降低缺血脑组织的神经功能缺损评分和脑梗死面积(P&lt;0.01),减轻缺血脑组织神经元和微血管ECs的病理改变和超微结构的损害。此外,它们上调了RUNX1,VEGF,Ang-1,Ang-2和VEGFR2(P&lt;0.01)以及vWF的蛋白质水平,CD34,RUNX1,VEGF,Ang-1、Ang-2和VEGFR2(P<0.01)。结果提示,在经证明的处方记录中,古今中外可通过调节RUNX1/VEGF通路促进MCAO大鼠缺血脑组织血管新生和侧支循环的建立,从而减轻其神经功能障碍。
    This paper aims to explore the effect of Xuming Decoction in the Records of Proved Prescriptions, Ancient and Modern on cerebral ischemic injury and angiogenesis in the rat model of acute cerebral infarction. SD rats were randomized into 6 groups: sham group, model group, low-, medium-, and high-dose(5.13, 10.26, and 20.52 g·kg~(-1), respectively) Xuming Decoction groups, and butylphthalide(0.06 g·kg~(-1)) group. After the successful establishment of the rat model by middle cerebral artery occlusion(MCAO), rats in the sham and model groups were administrated with distilled water and those in other groups with corresponding drugs for 7 consecutive days. After the neurological function was scored, all the rats were sacrificed, and the brain tissue samples were collected. The degree of cerebral ischemic injury was assessed by the neurological deficit score and staining with 2,3,5-triphenyltetrazolium chloride. Hematoxylin-eosin staining was performed to observe the pathological changes in the brain. Transmission electron microscopy was employed to observe the ultrastructures of neurons and microvascular endothelial cells(ECs) on the ischemic side of the brain tissue. Immunofluorescence assay was employed to detect the expression of von Willebrand factor(vWF) and hematopoietic progenitor cell antigen CD34(CD34) in the ischemic brain tissue. Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of Runt-related transcription factor 1(RUNX1), vascular endothelial growth factor(VEGF), angiopoietin-1(Ang-1), angiopoietin-2(Ang-2), and VEGF receptor 2(VEGFR2) in the ischemic brain tissue. The results showed that compared with the sham group, the model group showed increased neurological deficit score and cerebral infarction area(P<0.01), pathological changes, and damaged ultrastructure of neurons and microvascular ECs in the ischemic brain tissue. Furthermore, the modeling up-regulated the mRNA levels of RUNX1, VEGF, Ang-1, Ang-2, and VEGFR2(P<0.01) and the protein levels of vWF, CD34, RUNX1, VEGF, Ang-1, Ang-2, and VEGFR2(P<0.05 or P<0.01). Compared with the model group, high-dose Xuming Decoction and butylphthalide decreased the neurological deficit score and cerebral infarction area(P<0.01) and alleviated the pathological changes and damage of the ultrastructure of neurons and microvascular ECs in the ischemic brain tissue. Moreover, they up-regulated the mRNA levels of RUNX1, VEGF, Ang-1, Ang-2, and VEGFR2(P<0.01) and the protein levels of vWF, CD34, RUNX1, VEGF, Ang-1, Ang-2, and VEGFR2(P<0.01). The results suggest that Xuming Decoction in the Records of Proved Prescriptions, Ancient and Modern can promote the angiogenesis and collateral circulation establishment to alleviate neurological dysfunction of the ischemic brain tissue in MCAO rats by regulating the RUNX1/VEGF pathway.

    成人发作的斯蒂尔病(AOSD)是一种病因不明的罕见全身性炎症。中风是与AOSD相关的罕见并发症;其中大多数是由于小血管阻塞引起的脑梗死。这里,我们报道了1例因AOSD相关大血管闭塞导致脑梗死患者机械取栓的病例.一名没有潜在疾病的60岁男子被诊断患有AOSD。入院16天后,他突然失去知觉,被发现患有右偏瘫和失语症。头部CT显示左岛叶皮质缺血性梗死的早期征象,头部CT血管造影显示左大脑中动脉(MCA)部分闭塞。因此,我们认为机械取栓术是血运重建的指征.我们使用TrevoNXT4×28mm(Stryker,卡拉马祖,美国)并获得了MCA的再灌注。脑血管造影结果提示为栓塞性脑梗死,我们调查了栓塞的来源,包括可插入心脏监护仪(ICM)(RevealLINQ,美敦力,明尼阿波利斯,美国)。然而,除AOSD外,未观察到可能是栓塞来源的疾病.因此,AOSD被认为与栓塞有关。AOSD可能引起栓塞性脑梗死,可用于机械血栓切除术。
    Adult-onset Still\'s disease (AOSD) is a rare systemic inflammatory condition of an unknown etiology. Stroke is a rare complication associated with AOSD; most of these are cerebral infarctions due to the occlusion of small blood vessels. Here, we report the first case of mechanical thrombectomy in a patient with cerebral infarction due to a large vessel occlusion associated with AOSD. A 60-year-old man with no underlying disease was diagnosed with AOSD. Sixteen days after admission, he suddenly lost consciousness and was found to have right hemiplegia and aphasia. Head CT showed early signs of ischemic infarction in the left insular cortex, and head CT angiography demonstrated occlusion in a part of the left middle cerebral artery (MCA). Therefore, we decided that mechanical thrombectomy was an indication of revascularization. We performed mechanical thrombectomy using a Trevo NXT 4 × 28 mm (Stryker, Kalamazoo, USA) and obtained reperfusion of the MCA. The results of the cerebral angiography were indicative of an embolic cerebral infarction, and we investigated the source of the embolism including an insertable cardiac monitor (ICM) (Reveal LINQ, Medtronic, Minneapolis, USA). However, no disease other than AOSD that could be a source of embolism was observed. Therefore, AOSD was assumed to be associated with embolisms. AOSD may cause embolic cerebral infarction and may be indicated for mechanical thrombectomy.

    脑梗死是一种常见的神经系统疾病,发病率高,死亡率,和复发,对人类的生命和健康构成了极大的威胁。脑梗死是世界上第二大死亡原因,也是人类长期残疾的主要原因。2008年第三次全国死因回顾性抽样调查结果显示,脑梗死已成为我国的首要死因,其死亡率是欧美国家的4-5倍。因此,本文提出了一项Cmmi-MHR联合血栓弹力图参数对急性脑梗死的预测价值的研究。本文主要提出了一种高帧率成像技术,并对其算法进行了分析。在这篇文章中,在实验部分,对单核细胞与高密度脂蛋白胆固醇比值(MHR)联合血栓弹力图参数对急性脑梗死的预测价值进行了深入分析.最终实验结果表明,HDL(OR=1.695%,P趋势=0.049)在住院90天内有死亡的可能性(OR=0.81,95%CI=1.06-3.11,P趋势=0.523)。90天后死亡率无显著差异。不管调整年龄等混杂因素,性别,和NIHSS得分,住院90天内MHR或单核细胞计数的风险无显著差异.结论提示Cmmi-MHR与血栓弹力图参数的结合为脑梗死的诊断和治疗提供了新的视角和方法。为脑梗死的个性化治疗和管理提供重要支持。
    Cerebral infarction is a common neurological disease with high rates of morbidity, mortality, and recurrence, posing a great threat to human life and health. Cerebral infarction is the second leading cause of death in the world and the leading cause of long-term disability in humans. The results of the third national retrospective sampling survey on causes of death in 2008 showed that cerebral infarction has become the leading cause of death in China and its mortality rate is 4-5 times that of European and American countries. Therefore, this article proposed a study on the predictive value of Cmmi-MHR combined with thromboelastography parameters that was performed for acute cerebral infarction. This paper mainly proposed a high frame rate imaging technology and analyzed its algorithm. In this article, in the experimental part, an in-depth analysis of the predictive value of the Monocyte-to-high-density lipoprotein cholesterol ratio (MHR) combined with thromboelastography parameters was performed for acute cerebral infarction. The final experimental results showed that HDL (OR = 1.695%, P-trend = 0.049) had a probability of death within 90 days of hospitalization (OR = 0.81, 95% CI = 1.06-3.11, P-trend = 0.523). There were no significant differences in mortality rate after 90 days. Regardless of adjusting for confounders such as age, gender, and NIHSS score, there was no significant difference in the risk of MHR or monocyte count within 90 days of hospitalization. The conclusion indicates that the combination of Cmmi-MHR and thromboelastography parameters provides a new perspective and method for the diagnosis and treatment of cerebral infarction, and provides important support for personalized treatment and management of cerebral infarction.

    本研究旨在评估逐步住院康复计划(SIRP)对接受血管内支架植入治疗大血管闭塞患者的自我护理能力和生活质量的影响急性脑梗死(ACI)。
    本研究包括2020年1月至2024年2月在安徽医科大学第三附属医院接受血管内支架植入术的90例ACI患者。患者随访至少3个月。队列分组基于每位患者接受的护理类型。观察组参与SIRP并接受常规护理,对照组只接受常规护理。关键成果指标包括Barthel指数,美国国立卫生研究院卒中量表(NIHSS)评分,并发症的发生率,住院时间,和36项简短调查(SF-36)得分。比较两组的这些参数。
    在入学时,人口统计数据没有显着差异,NIHSS得分,Barthel指数,观察组和对照组的SF-36评分(均P>0.05)。然而,术后3个月,观察组显着改善,在Barthel指数中平均得分较高(62.49±7.32vs.53.16±4.37,p<0.001)和SF-36评分(502.33±14.28vs.417.64±9.65,p<0.001)。此外,该组NIHSS评分明显较低(3.38±1.19vs.10.24±2.10,p<0.001),更少的并发症(3vs.15,p=0.002),和较短的住院时间(12.40±1.68vs.15.56±1.87,p<0.001)。
    实施SIRP显着增强了自我护理能力和整体生活质量,同时还降低了接受血管内支架植入术的ACI患者的并发症发生率和住院时间。这强调了将结构化康复计划纳入此类患者的治疗和康复过程的潜在好处。
    UNASSIGNED: This study aims to evaluate the influence of a step-by-step inpatient rehabilitation program (SIRP) on the self-care capability and quality of life of patients who have undergone intravascular stent implantation to treat large vessel occlusion during acute cerebral infarction (ACI).
    UNASSIGNED: This study included a cohort of 90 patients with ACI who received intravascular stent implantations at a tertiary hospital in the Third Affiliated Hospital of Anhui Medical University from January 2020 to February 2024. The patients were followed up for at least 3 months. Cohort grouping was based on the type of nursing care each patient received. The observation group participated in SIRP along with receiving routine nursing care, whereas the control group received only routine nursing care. Key outcome measures included the Barthel index, the National Institute of Health Stroke Scale (NIHSS) score, the incidence of complications, length of hospital stay, and 36-item short-form survey (SF-36) scores. These parameters were compared between the two groups.
    UNASSIGNED: At the time of admission, there were no significant differences in demographic data, NIHSS score, Barthel index, or SF-36 scores between the observation and control groups (all p > 0.05). However, at 3 months postoperatively, the observation group showed significant improvements, with higher average scores in the Barthel index (62.49 ± 7.32 vs. 53.16 ± 4.37, p < 0.001) and SF-36 scores (502.33 ± 14.28 vs. 417.64 ± 9.65, p < 0.001). Additionally, this group had significantly lower NIHSS scores (3.38 ± 1.19 vs. 10.24 ± 2.10, p < 0.001), fewer complications (3 vs. 15, p = 0.002), and shorter hospital stays (12.40 ± 1.68 vs. 15.56 ± 1.87, p < 0.001).
    UNASSIGNED: Implementing SIRP notably enhanced self-care capabilities and overall quality of life, while also reducing complication rates and the length of hospital stays for patients with ACI who underwent intravascular stent implantation. This underscores the potential benefits of incorporating structured rehabilitation programs in the treatment and recovery processes of such patients.

    探讨中青年急性脑梗死(ACI)患者重度饮酒的临床特点及预后。
    从2018年6月至2020年12月,共有263名中青年ACI患者被纳入研究,并分为重度饮酒者和非重度饮酒者。进行多因素logistic回归分析以评估ACI与重度饮酒之间的关联。考虑临床特征和出院后一年的预后。
    在患者中,78人是酗酒者。重度饮酒者在ACI发作前24小时更有可能饮酒(OR4.03,95%CI2.26-7.20),特别是以白酒的形式(OR3.83,95%CI1.59-9.20),入院时舒张压≥90mmHg的风险较高(OR2.02,95%CI1.12-3.64).在出院后一年的预后中,重度饮酒者在3个月时预后不良的可能性更大(OR2.31,95%CI1.01-5.25),出院后戒烟的可能性较小(OR0.36,95%CI0.19-0.66),并且复发脑梗死的风险较高(OR2.79,95%CI1.14-6.84)。
    经过12个月的随访,大量饮酒的中青年ACI患者的短期预后较差。控制饮酒水平可以改善这些患者的预后。
    UNASSIGNED: To investigate the clinical characteristics and prognosis of heavy alcohol consumption among young and middle-aged patients with acute cerebral infarction (ACI).
    UNASSIGNED: A total of 263 young and middle-aged ACI patients were included in the study from June 2018 to December 2020 and classified into heavy drinkers and non-heavy drinkers. Multivariate logistic regression analysis was conducted to assess the association between ACI and heavy alcohol consumption, considering clinical characteristics and one-year post-discharge prognosis.
    UNASSIGNED: Among the patients, 78 were heavy drinkers. Heavy drinkers were more likely to consume alcohol 24 h before ACI onset (OR 4.03, 95 % CI 2.26-7.20), especially in the form of liquor (OR 3.83, 95 % CI 1.59-9.20), and had a higher risk of diastolic blood pressure ≥90 mmHg upon admission (OR 2.02, 95 % CI 1.12-3.64). In the one-year post-discharge prognosis, heavy drinkers had a greater likelihood of poor prognosis at 3 months (OR 2.31, 95 % CI 1.01-5.25), were less likely to quit drinking after discharge (OR 0.36, 95 % CI 0.19-0.66), and had a higher risk of recurrent cerebral infarction (OR 2.79, 95 % CI 1.14-6.84).
    UNASSIGNED: Over the 12-month follow-up, young and middle-aged ACI patients with heavy alcohol consumption exhibited worse short-term prognosis. Controlling alcohol consumption levels may improve the prognosis of these patients.

    目的:通过评估急性脑梗死患者lncRNALINC01123(LINC01123)结合纤维蛋白原的表达及潜在分子机制,探讨其在急性脑梗死(ACI)中的诊断价值及临床意义。
    方法:收集所有志愿者的临床资料。RT-qPCR检测ACI患者血清LINC01123程度。通过Pearson相关分析研究LINC01123与纤维蛋白原的关系。应用ROC曲线评价LINC01123和纤维蛋白原对ACI的诊断价值。采用二元Logistic回归分析探讨ACI的危险因素。并通过荧光素酶活性测定验证LINC01123与下游miR-361-3p的靶向关系。
    结果:与健康对照组相比,ACI患者的血清LINC01123和纤维蛋白原水平上调(P<0.001),两者呈正相关(r=0.6537,P<0.001)。LINC01123和纤维蛋白原对预测ACI的发生有较高的诊断价值,联合诊断的AUC为0.961,敏感性和特异性(92.54%,85.82%)更显著。同时,LINC01123和纤维蛋白原是ACI的独立危险因素(P<0.0001)。机械上,miR-361-3p是LINC01123的靶标。miR-361-3p在ACI患者血清中表达较低,与LINC01123表达呈负相关(r=-0.6885,P<0.0001)。
    结论:LINC01123联合纤维蛋白原作为血清标志物对ACI的诊断有重要的参考价值。这可能成为预测ACI发生的临床指标。
    To explore the diagnostic value and clinical significance of lncRNA LINC01123 (LINC01123) binding fibrinogen in acute cerebral infarction (ACI) by evaluating the expression and potential molecular mechanism of LINC01123 in patients with acute cerebral infarction.
    The clinical data of all the volunteers were collected. The level of serum LINC01123 in ACI patients was detected by RT-qPCR. The relationship between LINC01123 and fibrinogen was studied via Pearson\'s correlation analysis. ROC curve was used to evaluate the diagnostic value of LINC01123 and fibrinogen for ACI. The risk factors of ACI were investigated by Binary Logistic regression analysis. And the targeting relationship between LINC01123 and downstream miR-361-3p was verified through luciferase activity assay.
    Serum LINC01123 and fibrinogen levels were upregulated in ACI patients compared with healthy controls (P < 0.001), and there was a positive correlation between them (r = 0.6537, P < 0.001). In predicting the occurrence of ACI, LINC01123 and fibrinogen have high diagnostic value, and the AUC of combined diagnosis was 0.961, and the sensitivity and specificity (92.54%, 85.82%) were more significant. Meanwhile, LINC01123 and fibrinogen were confirmed to be independent risk factors for ACI (P < 0.0001). Mechanistically, miR-361-3p is the target of LINC01123. The expression of miR-361-3p was low in the serum of ACI patients, which was negatively correlated with the LINC01123 expression (r = -0.6885, P < 0.0001).
    LINC01123 combined with fibrinogen may have important reference value in the diagnosis of ACI as serum markers, which may become clinical indicators to predict the occurrence of ACI.

    方法:在本研究中,前瞻性选择158例ACI患者,并随机分为对照组(仅给予对症药物)和RIPC组(根据药物对四肢进行RIPC)。与他们的临床基线数据记录。血清miR-582-5p水平,采用RT-qPCR/ELISA检测HMGB1和炎症因子[肿瘤坏死因子α(TNF-α)/白细胞介素-1β(IL-1β)/IL-10],然后使用全自动生化分析仪比较氧化应激指标[谷胱甘肽过氧化物酶(GSH-Px)/过氧化氢酶(CAT)/超氧化物歧化酶(SOD)]。采用Pearson分析检测血清miR-582-5p与血清HMGB1的相关性,以及与TNF-α/IL-1β/IL-10的相关性。采用NIHSS评分/Barthel指数量表评定神经功能/日常生活能力。评估ACI患者的干预安全性。
    结果:RIPC干预增加ACI患者血清miR-582-5p水平,降低血清HMGB1水平。RIPC干预显着降低炎症(TNF-α/IL-1β水平降低,ACI患者的IL-10水平升高)和氧化应激(GSH-Px/CAT/SOD水平升高)。血清miR-582-5p与TNF-α、IL-1β水平呈负相关,虽然与IL-10水平呈正相关,而HMGB1与TNF-α、IL-1β水平呈正相关,而与IL-10水平呈负相关。miR-582-5p与HMGB1呈负相关。RIPC干预改善神经功能(降低NIHSS,在一定程度上增加了ACI患者的Barthel评分)。RIPC治疗ACI具有一定的有效性和安全性。
    结论:在RIPC干预后,血清miR-582-5p水平升高,HMGB1水平下降,ACI患者的炎症和氧化应激减少,减轻了神经功能缺损,提高患者进行生活活动的能力,并在一定程度上发挥了神经保护作用。
    Acute cerebral infarction (ACI) contributes to disability and death accross the globe. Remote ischemic preconditioning (RIPC) reduces cerebral infarct size and improves neurological function in ACI. We conducted this research to reveal the effects of RIPC intervention on serum levels of microRNA-582-5p (miR-582-5p)/high mobility group box-1 protein (HMGB1), inflammation, oxidative stress and neurological function in patients with ACI.
    In this study, 158 patients with ACI were prospectively selected and randomized into the control (administered symptomatic medication alone) and the RIPC (underwent RIPC of the limbs based on medication) groups, with their clinical baseline data documented. Serum levels of miR-582-5p, and HMGB1 and inflammatory factors [tumor necrosis factor alpha (TNF-α)/interleukin-1beta (IL-1β)/IL-10] were assessed by RT-qPCR/ELISA, followed by comparisons of oxidative stress indices [glutathione-peroxidase (GSH-Px)/catalase (CAT)/superoxide dismutase (SOD)] using a fully automatic biochemical analyzer. Correlations between serum miR-582-5p with serum HMGB1, and between their levels with TNF-α/IL-1β/IL-10 were analyzed by Pearson analysis. The NIHSS score/Barthel Index scale were used to assess neurological function/daily living ability. Intervention safety for ACI patients was evaluated.
    RIPC intervention increased serum miR-582-5p levels and decreased serum HMGB1 levels in ACI patients. RIPC intervention significantly reduced inflammation (diminished TNF-α/IL-1β levels, increased IL-10 level) and oxidative stress (elevated GSH-Px/CAT/SOD levels) in ACI patients. Serum miR-582-5p was negatively correlated with TNF-α and IL-1β levels, while positively correlated with IL-10 level, while HMGB1 was positively correlated with TNF-α and IL-1β levels, while negatively correlated with IL-10 level. miR-582-5p was negatively correlated with HMGB1. RIPC intervention improved neurological function (reduced NIHSS, increased Barthel scores) in ACI patients to some extent. RIPC had certain effectiveness and safety in the treatment of ACI.
    After RIPC intervention, serum miR-582-5p levels were increased, HMGB1 levels were decreased, and inflammation and oxidative stress were reduced in ACI patients, which mitigated neurological deficits, improved patients\' ability to perform life activities, and exerted neuroprotective effects to some extent.
