    抗血栓治疗是心血管疾病治疗的重要手段,临床研究显示抗血栓治疗增加脑微出血灶数量,并可能导致脑出血,临床医生可能会因此削弱原有的抗血栓治疗强度。然而,目前的专家共识或指南未明确在脑微出血情况下抗血栓方案的调整策略。该文回顾近年文献资料,认为以脑淀粉样血管病为病因的脑微出血导致的脑出血风险更高,但总体出血事件发生率仍低于缺血性卒中发生率。目前的证据尚不支持因脑微出血的存在而改变抗血栓策略,但在合并脑淀粉样血管病的高龄患者或合并高危表型的患者中,应调整抗凝方案,并动态监测脑微出血灶的变化。.

    为了探索膳食锌摄入量与心血管疾病(CVDs)之间的关系,包括充血性心力衰竭(CHF),冠心病,心绞痛,心脏病发作,脑血管意外(CVA),进行了这项研究.
    这项研究使用了国家健康和营养检查调查(2005-2018年)的数据。膳食锌摄入量被分层为四分位数。构造了受限制的三次样条,以评估非线性关联并根据非线性类型确定截止值。使用截止值进行二元逻辑回归。
    在第二个之间检测到正相关,第三,和第四分位数的膳食锌摄入量和总心血管疾病的风险降低(Q2:OR=0.83,95%CI=0.72-0.96;Q3:OR=0.83,95%CI=0.71-0.96;Q4:OR=0.79,95%CI=0.67-0.93).第二个,第三,和第四分位数与各种CVD的风险降低显着相关(均P<0.05),除冠心病和心绞痛外(均P>0.05)。限制性三次样条回归显示,膳食锌摄入量与发生CVDs和CHF的风险之间存在显著的非线性趋势(非线性均P<0.05),而对于心脏病发作和CVA的那些则有轻微显著性(非线性的P分别为0.072和0.075)。
    这项研究表明,高锌摄入量与降低心血管疾病的风险有关,CHF,心脏病发作,还有CVA,但不是冠心病或心绞痛。
    UNASSIGNED: To explore the associations between dietary zinc intake and cardiovascular diseases (CVDs), including congestive heart failure (CHF), coronary heart disease (CHD), angina, heart attack, and cerebrovascular accident (CVA), this study was performed.
    UNASSIGNED: Data from the National Health and Nutrition Examination Survey (2005-2018) were used in this study. Dietary zinc intake was stratified into quartiles. Restricted cubic splines were constructed to assess nonlinear associations and identify cut-off values based on the type of nonlinearity. Binary logistic regressions were performed using the cut-offs.
    UNASSIGNED: Positive associations were detected between the second, third, and fourth quantiles of dietary zinc intake and decreased risks of overall CVDs (Q2: OR = 0.83, 95 % CI = 0.72-0.96; Q3: OR = 0.83, 95 % CI = 0.71-0.96; Q4: OR = 0.79, 95 % CI = 0.67-0.93). The second, third, and fourth quantiles were significantly associated with decreased risks of various CVDs (all P < 0.05), except for CHD and angina (all P > 0.05). Restricted cubic spline regression revealed significant nonlinear trends for associations of dietary zinc intake with the risk of developing CVDs and CHF (both P for nonlinear <0.05), whereas those for heart attack and CVA were marginally significant (P for nonlinear = 0.072, and 0.075, respectively).
    UNASSIGNED: This study revealed that high dietary zinc intake is associated with reduced risks of developing CVDs, CHF, heart attack, and CVA, but not CHD or angina.

    Cardiovascular and cerebrovascular disease (CCVD) is a complex disease with a long latency period, and the most effective diagnosis and treatment methods are risk assessment and preventive interventions before onset. According to traditional Chinese medicine (TCM), Zhu-Ye-Qing wine (ZYQW) has the effect of invigorating blood and removing blood stasis. However, whether ZYQW can improve the progression of CCVD has not been reported. This study aims to explore the possible mechanism of ZYQW on CCVD through network pharmacology, and finally 249 potential targets of ZYQW and 2080 potential targets of CCVD are obtained. The key targets mainly include MAPK3, TP53, RELA, MAPK1 and AKT1. The main KEGG pathways include TNF signaling pathway, lipid and atherosclerosis pathway signaling pathway. The components in ZYQW are identified by ultra-performance liquid chromatography-mass spectrometry (UHPLC-CQE-CQE-MS/MS). Through network pharmacology, molecular docking and molecular dynamics simulation, the potential key components and prevention mechanisms of ZYQW in the prevention of CCVD are determined. ZYQW may be an effective and safe health food for the prevention of CCVD, providing guidance and basis for the further development of medicinal foods.

    先前的研究表明,甘油三酸酯葡萄糖-体重指数(TyG-BMI)与腹膜透析患者的心血管死亡率有关。然而,TyG-BMI对急性心肌梗死(AMI)预后的预测价值尚不清楚.
    总共,408例接受PCI的AMI患者连续纳入本研究。然后根据TyG-BMI的三元率将所有纳入的患者分为三组。研究了TyG-BMI与主要不良心脑血管事件(MACCEs)之间的关系。
    参与者被分为三组:tertile1(≤199.4,n=136),Tertile2(199.4-231.8,n=136),和三元组3(≥231.8,n=136)。80例(19.6%)患者患有MACCE:1个三等组18例(13.2%),2个三等组26例(19.1%),3个三等组36例(25.7%)。MACCE的发生率随着TyG-BMI的三位数的增加而增加(p<0.05)。多因素Cox回归分析显示,糖尿病和TyG-BMI是AMI患者PCI术后MACCEs的独立预测因子(p<0.05)。受试者工作特征(ROC)曲线显示,当TyG-BMI≥192.4时,灵敏度和特异度分别为60.1%和65.4%。分别,ROC曲线下面积(AUC)为0.632(95%置信区间[CI]:0.562-0.703;p<0.001)。
    TyG-BMI水平升高是AMI患者PCI术后复合MACCEs的独立预测因子。
    UNASSIGNED: Previous studies have suggested that triglyceride glucose-body mass index (TyG-BMI) is associated with cardiovascular mortality in patients undergoing peritoneal dialysis. However, the predictive value of TyG-BMI in the prognosis of acute myocardial infarction (AMI) remains unclear.
    UNASSIGNED: In total, 408 AMI patients who underwent PCI were consecutively included in this study. All included patients were then divided into three groups according to tertiles of TyG-BMI. The association between TyG-BMI and major adverse cardiovascular and cerebrovascular events (MACCEs) were investigated.
    UNASSIGNED: Participants were divided into three groups: tertile 1(≤199.4, n=136), tertile 2 (199.4-231.8, n=136), and tertile 3 (≥231.8, n=136). Eighty (19.6%) patients had MACCEs: 18 (13.2%) in tertile 1, 26 (19.1%) in tertile 2, and 36 (25.7%) in tertile 3. The incidence of MACCEs increased as the tertiles of TyG-BMI increased (p<0.05). Multivariate Cox regression analysis revealed that diabetes mellitus and TyG-BMI were independent predictors of MACCEs in AMI patients after PCI (p<0.05). The receiver operating characteristic (ROC) curve showed that when TyG-BMI was ≥192.4, the sensitivity and specificity were 60.1% and 65.4%, respectively, and the area under the ROC curve (AUC) was 0.632 (95% confidence interval [CI]: 0.562-0.703; p < 0.001).
    UNASSIGNED: Elevated TyG-BMI level was an independent predictor of the composite MACCEs in patients with AMI after PCI.

    趋化因子样因子1(CKLF1)是一种新型的非典型趋化因子,越来越多的作品证明了在心脑血管疾病(CCVD)中起着至关重要的作用。在心血管疾病中,包括动脉粥样硬化和心肌梗塞,同时在缺血性中风和出血性中风等脑血管疾病中,CKLF1的表达水平明显变化,通过与其功能受体结合来触发下游信号通路,然后发挥多重效应参与这些CCVD的发生发展。CKLF1的功能作用是动态的,CKLF1可能是一把双刃剑。CCVDs的促进作用与招募炎症细胞有关,增强血管平滑肌细胞和内皮细胞的增殖,而CCVDs的抑制作用可能与神经细胞的迁移和促进造血干细胞增殖有关,这有助于疾病的恢复。基于此,本文旨在回顾表达变化,潜在角色,和CCVDs中CKLF1的分子机制,CKLF1靶向治疗策略的现状也包括在内。我们希望这篇综述可以为使用CKLF1作为CCVD的诊断和预后生物标志物或开发新的治疗方法提供有价值的参考。
    Chemokine like factor 1 (CKLF1) is a novel atypical chemokine, playing a crucial role in cardiovascular and cerebrovascular diseases (CCVDs) demonstrated by a growing body of works. In cardiovascular diseases including atherosclerosis and myocardial infarction, meanwhile in cerebrovascular diseases such as ischemic stroke and hemorrhagic stroke, the expression levels of CKLF1 change markedly, which triggers downstream signaling pathways by binding with its functional receptors, and then exerts multiple effects to participate in the occurrence and development of these CCVDs. The functional roles of CKLF1 are dynamic and CKLF1 may act as a double-edged sword. The CCVDs-promoting role is related to recruiting inflammatory cells, enhancing the proliferation of vascular smooth muscle cells and endothelial cells, while the CCVDs-suppressing role may correlate with migration of nerve cells and promotion of hematopoietic stem cell proliferation which contributes to disease recovery. Based on this, the paper intends to review expression shifts, potential roles, and molecular mechanisms of CKLF1 in CCVDs, and the current status of CKLF1 targeted therapeutic strategies is also included. We hope this review may provide a valuable reference for using CKLF1 as a diagnostic and prognostic biomarker for CCVDs or developing novel treatments.

    丙酮酸激酶M2(PKM2),一种参与糖酵解的关键酶,在不同生理条件下对调节细胞代谢和生长具有重要作用。PKM2在多种癌症疾病中已被深入研究。近年来,许多研究发现其在脑血管疾病(CeVD)中的关键作用,颅内血液循环紊乱.CeVD已被证实与氧化应激(OS)密切相关,线粒体动力学,全身性炎症,和大脑中的局部神经炎症。进一步揭示了PKM2在调节能量供应方面发挥着多种生物学功能,操作系统,炎症反应,和线粒体功能障碍。PKM2的作用与其不同的亚型密切相关,亚细胞定位中的表达水平,和翻译后修饰。因此,总结PKM2在CeVDs中的作用将有助于进一步理解CeVDs的分子机制。在这次审查中,我们说明了PKM2的特征,调节的PKM2表达,以及PKM2在CeVD中的生物学作用。
    Pyruvate kinase M2 (PKM2), a key enzyme involved in glycolysis,plays an important role in regulating cell metabolism and growth under different physiological conditions. PKM2 has been intensively investigated in multiple cancer diseases. Recent years, many studies have found its pivotal role in cerebrovascular diseases (CeVDs), the disturbances in intracranial blood circulation. CeVDs has been confirmed to be closely associated with oxidative stress (OS), mitochondrial dynamics, systemic inflammation, and local neuroinflammation in the brain. It has further been revealed that PKM2 exerts various biological functions in the regulation of energy supply, OS, inflammatory responses, and mitochondrial dysfunction. The roles of PKM2 are closely related to its different isoforms, expression levels in subcellular localization, and post-translational modifications. Therefore, summarizing the roles of PKM2 in CeVDs will help further understanding the molecular mechanisms of CeVDs. In this review, we illustrate the characteristics of PKM2, the regulated PKM2 expression, and the biological roles of PKM2 in CeVDs.

    尽管在治疗方式如分流器方面取得了进步,后交通动脉(PComA)动脉瘤的最佳治疗仍不确定.虽然已经报道了用管道栓塞装置(PED)治疗的PComA动脉瘤,不完全闭塞动脉瘤的特征和进展仍不清楚.因此,本研究旨在探讨PED治疗PComA动脉瘤的闭塞状态和复发率.对2015年1月至2020年12月期间接受PED治疗的连续PComA动脉瘤患者进行了回顾性研究。仅包括接受放射学随访的患者。PComA动脉瘤分为不完全闭塞组和完全闭塞组。主要结果包括随访血管造影时不完全闭塞的特征。在我们机构接受PED治疗的121例PComA动脉瘤中,80个动脉瘤符合我们的研究条件。在后续期间,19例(23.8%)动脉瘤显示不完全闭塞。值得注意的是,在80例随访病例中,没有复发.患者和动脉瘤的基线特征在完全和不完全闭塞组之间具有可比性。然而,不完全闭塞组的辅助弹簧圈栓塞率较低(21.2%vs.55.7%,P=0.017)和较短的中位手术时间(91.0vs.145.5分钟,P=0.039)。功能结果的差异,并发症,且PComA闭塞状态组间差异无统计学意义。多变量分析显示使用线圈与PComA动脉瘤不完全闭塞的几率较低相关(OR0.01,95%CI0.001-0.12;P=0.001),而动脉瘤大小与较高的不完全闭塞几率相关(OR1.25,95%CI1.10-1.46;P=0.002).PED治疗PComA动脉瘤的结果良好,不完全闭塞率可接受,未观察到复发。然而,需要进一步的研究来探索大型PComA动脉瘤的最佳手术策略.
    Despite advancements in treatment modalities such as flow diverters, the optimal management of posterior communicating artery (PComA) aneurysms remains uncertain. While PComA aneurysms treated with the Pipeline Embolization Device (PED) has been reported, the characteristics and progression of incomplete occluded aneurysms remain unclear. Therefore, our study aims to investigate the occlusion status and recurrence rates of PComA aneurysms treated with PED. A retrospective review of consecutive PComA aneurysm patients treated with PED was conducted between January 2015 and December 2020. Only patients with radiological follow-up were included. PComA aneurysms were categorized into incomplete occlusion and complete occlusion group. The primary outcomes included the characteristics of incomplete occlusion at the follow-up angiography. Among 121 PComA aneurysms treated with PED at our institution, 80 aneurysms were eligible in our study. During the follow-up period, 19 (23.8%) aneurysms demonstrated incomplete occlusion. Notably, there were no instances of recurrence among the 80 followed-up cases. Baseline characteristics of patients and aneurysms were comparable between the groups with complete and incomplete occlusion. However, the incomplete occlusion group showed a lower rate of assisted coils embolization (21.2% vs. 55.7%, P = 0.017) and shorter median operative time (91.0 vs. 145.5 min, P = 0.039). Differences in functional outcomes, complications, and PComA occlusion status between the groups were not significant. Multivariate analysis revealed the use of coils was associated with lower odds of incomplete PComA aneurysm occlusion (OR 0.01, 95% CI 0.001-0.12; P = 0.001), while aneurysm size was associated with higher odds of incomplete occlusion (OR 1.25, 95% CI 1.10-1.46; P = 0.002). The treatment of PED for PComA aneurysm demonstrated favorable outcomes, with an acceptable rate of incomplete occlusion and no instances of recurrence observed. However, further research is needed to explore the optimal procedural strategy for large-sized PComA aneurysms.

    甘油三酯-葡萄糖(TyG)指数是胰岛素抵抗和代谢异常的替代指标,与多种疾病的预后密切相关。患有冠心病和抑郁症的患者发生主要不良心血管和脑血管事件(MACCE)的风险更高,预后更差。TyG指数可能能够预测这一特殊人群的不良预后。
    回顾性队列研究纳入了2013年6月至2023年12月期间的596例冠心病和抑郁症患者。主要终点是MACCE的发生,包括全因死亡,中风,心肌梗死和急诊冠状动脉血运重建。接收机工作特性(ROC)曲线,Cox回归分析,Kaplan-Meier生存分析,采用限制性三次样条(RCS)分析评价冠心病合并抑郁症患者的TyG指数与MACCE风险的相关性。
    中位随访时间为31(15-62)个月,281例(47.15%)患者发生MACCE。预测MACCE风险的TyG指数ROC曲线下面积为0.765(0.726~0.804)(P<0.01)。高TyG指数组(69.73%)患者发生MACCE的风险明显高于低TyG指数组(23.63%)(P<0.01)。多因素RCS模型表现出非线性相关(非线性P<0.01,总体P<0.01),TyG指数的临界值为8.80,以预测MACCE的发生。TyG指数能够进一步提高MACCE的预测准确性。
    TyG指数是冠心病合并抑郁症患者MACCE风险的潜在预测因子。
    UNASSIGNED: Triglyceride-glucose (TyG) index is a surrogate marker of insulin resistance and metabolic abnormalities, which is closely related to the prognosis of a variety of diseases. Patients with both CHD and depression have a higher risk of major adverse cardiovascular and cerebrovascular events (MACCE) and worse outcome. TyG index may be able to predict the adverse prognosis of this special population.
    UNASSIGNED: The retrospective cohort study involved 596 patients with both CHD and depression between June 2013 and December 2023. The primary outcome endpoint was the occurrence of MACCE, including all-cause death, stroke, MI and emergent coronary revascularization. The receiver operating characteristic (ROC) curve, Cox regression analysis, Kaplan-Meier survival analysis, and restricted cubic spline (RCS) analysis were used to assess the correlation between TyG index and MACCE risk of in patients with CHD complicated with depression.
    UNASSIGNED: With a median follow-up of 31 (15-62) months, MACCE occurred in 281(47.15%) patients. The area under the ROC curve of TyG index predicting the risk of MACCE was 0.765(0.726-0.804) (P<0.01). Patients in the high TyG index group(69.73%) had a significantly higher risk of developing MACCE than those in the low TyG index group(23.63%) (P<0.01). The multifactorial RCS model showed a nonlinear correlation (nonlinear P<0.01, overall P<0.01), with a critical value of 8.80 for the TyG index to predict the occurrence of MACCE. The TyG index was able to further improve the predictive accuracy of MACCE.
    UNASSIGNED: TyG index is a potential predictor of the risk of MACCE in patients with CHD complicated with depression.

    目的:选择2型糖尿病(T2D)的初始治疗方法至关重要,需要考虑坚实的临床证据和患者特征。尽管二甲双胍的历史偏好,其预防脑血管事件的疗效缺乏经验验证.这项研究旨在评估一线单一疗法(二甲双胍或非二甲双胍抗糖尿病药物)与无糖尿病并发症的T2D患者脑血管并发症之间的关系。
    方法:我们分析了9090例无并发症的T2D患者,这些患者使用二甲双胍或非二甲双胍药物作为初始治疗。倾向得分匹配确保了群体可比性。Cox回归分析,按最初使用二甲双胍分层,评估脑血管疾病风险,调整多个协变量并使用竞争风险分析。使用累积确定的每日剂量测量二甲双胍暴露。
    结果:与未使用二甲双胍的患者相比,使用二甲双胍的患者脑血管疾病的粗发病率显著降低(p<0.0001)。调整后的风险比(aHRs)一致显示二甲双胍使用与总体脑血管疾病(aHRs:0.67-0.69)和严重事件(aHRs:0.67-0.69)的较低风险之间存在关联。在所有模型中,与轻度脑血管疾病风险降低的相关性均显着(aHRs:0.73-0.74)。较高的二甲双胍每日累积剂量与脑血管风险降低相关(发生率比:0.62-0.94,p<0.0001),表明剂量依赖性效应。
    结论:二甲双胍单药治疗与T2D早期脑血管疾病风险降低相关,强调其剂量依赖性疗效。然而,观察到的益处也可能受到基线差异和与其他药物相关的风险增加的影响,如磺酰脲类。这些发现强调了个性化糖尿病管理的必要性,特别是在减轻早期T2D阶段的脑血管风险方面。
    OBJECTIVE: Choosing the initial treatment for type 2 diabetes (T2D) is pivotal, requiring consideration of solid clinical evidence and patient characteristics. Despite metformin\'s historical preference, its efficacy in preventing cerebrovascular events lacked empirical validation. This study aimed to evaluate the associations between first-line monotherapy (metformin or non-metformin antidiabetic medications) and cerebrovascular complications in patients with T2D without diabetic complications.
    METHODS: We analysed 9090 patients with T2D without complications who were prescribed either metformin or non-metformin medications as initial therapy. Propensity score matching ensured group comparability. Cox regression analyses, stratified by initial metformin use, assessed cerebrovascular disease risk, adjusting for multiple covariates and using competing risk analysis. Metformin exposure was measured using cumulative defined daily doses.
    RESULTS: Metformin users had a significantly lower crude incidence of cerebrovascular diseases compared with non-users (p < .0001). Adjusted hazard ratios (aHRs) consistently showed an association between metformin use and a lower risk of overall cerebrovascular diseases (aHRs: 0.67-0.69) and severe events (aHRs: 0.67-0.69). The association with reduced risk of mild cerebrovascular diseases was significant across all models (aHRs: 0.73-0.74). Higher cumulative defined daily doses of metformin correlated with reduced cerebrovascular risk (incidence rate ratio: 0.62-0.94, p < .0001), indicating a dose-dependent effect.
    CONCLUSIONS: Metformin monotherapy is associated with a reduced risk of cerebrovascular diseases in early-stage T2D, highlighting its dose-dependent efficacy. However, the observed benefits might also be influenced by baseline differences and the increased risks associated with other medications, such as sulphonylureas. These findings emphasize the need for personalized diabetes management, particularly in mitigating cerebrovascular risk in early T2D stages.
