目的 探索脑血管病患者主观性失眠与慢性期功能预后的关系。 方法 本研究是对多中心、大型前瞻性研究——中国卒中后抑郁发生及其结局的前瞻性队列研究（prospective cohort study on the incidence and outcome of patients with post-stroke depression in China，PRIOD）的事后分析。选取PRIOD中入组患者人数较多的15个中心，对入组的脑血管病患者进行发病5年后的电话随访。收集患者的一般资料、临床特点。根据《精神障碍诊断与统计手册》（第五版）中失眠的诊断标准编制调查问卷，收集失眠及相关睡眠问题，评估患者是否存在主观性失眠以及睡眠时间。采用mRS评估患者的功能预后。采用多因素logistic回归分析脑血管病患者主观性失眠与功能预后的关系。 结果 本研究共纳入698例患者，其中319例（45.70%）为主观性失眠患者，仅17.55%（56/319）服用助眠药物。logistic回归分析显示，主观性失眠与脑血管病患者功能预后存在显著关联：校正协变量后，与无失眠患者相比，主观性失眠患者功能残疾风险较高（OR 1.64，95%CI 1.11～2.42，P=0.013）；亚组分析显示，在基线为首次脑血管病发作患者中，与无失眠患者相比，主观性失眠患者功能残疾的风险较高（OR 1.74，95%CI 1.13～2.68，P=0.013）。 结论 主观性失眠是导致脑血管病慢性期功能残疾的危险因素。 Abstract: Objective To explore the relationship between subjective insomnia and functional prognosis in the chronic phase of patients with cerebrovascular disease. Methods This study is a post-hoc analysis of the multicenter, large-scale prospective study— prospective cohort study on the incidence and outcome of patients with post-stroke depression in China (PRIOD). Fifteen centers with a high number of patients enrolled in the PRIOD were selected, and the patients were followed up by telephone 5 years after the onset of cerebrovascular disease. General information and clinical characteristics were collected. According to the diagnostic criteria of insomnia in the Diagnostic & Statistical Manual of Mental Disorders (Fifth Edition), a questionnaire was compiled to collect data on insomnia and related sleep issues, and to assess the presence of subjective insomnia and sleep duration. The functional prognosis was evaluated by mRS. Multivariate logistic regression was used to analyze the relationship between subjective insomnia and functional prognosis in cerebrovascular disease patients. Results A total of 698 patients were included, of which 319 (45.70%) had subjective insomnia. Only 17.55%(56/319) were taking sleep aids. Logistic regression analysis revealed a significant association between subjective insomnia and functional prognosis in cerebrovascular disease patients: after adjusting for covariates, subjective insomnia patients had a higher risk of functional disability compared to those without insomnia (OR 1.64, 95%CI 1.11-2.42, P=0.013). Subgroup analysis showed that among patients experiencing their first cerebrovascular event at baseline, those with subjective insomnia had a higher risk of functional disability compared to those without insomnia (OR 1.74, 95%CI 1.13-2.68, P=0.013). Conclusions Subjective insomnia is a risk factor for functional disability in the chronic phase of patients with cerebrovascular disease.

永存动脉是永久性颈内动脉和椎基底动脉之间的异常吻合，是一种较罕见的脑血管变异。通常，永存动脉具有供血功能，不引起任何特殊临床症状，但若伴发动脉粥样硬化性病变和其他血管变异，会导致临床表现复杂化。目前，超声是临床评估头颈血管病变的首选检查方法，正确诊断永存动脉，可以更准确地解释与其相关的临床表现，在进行相应手术或介入操作时，可避免不当操作的风险。永存动脉多为影像学检查偶然发现，其影像学表现具有特征性。目前，国内外不乏对永存动脉的影像学诊断报道，但缺乏超声对永存动脉分型及其血流动力学的评估报道。本文结合文献，创新性地提出永存动脉的超声诊断思路和分型，旨在提高对永存动脉的早期准确诊断率。 Abstract: Persistent artery is an abnormal anastomotic branch between the permanent internal carotid artery and the vertebrobasilar artery, which is a rare cerebrovascular variation. Typically, persistent arteries have a blood supply function and do not cause specific clinical symptoms; however, when accompanied by atherosclerotic lesions of the arteries and other vascular variants, they result in a complex clinical presentation. At present, ultrasonography is the first choice for clinical evaluation of cerebral and cervical vascular abnormalities. Correct diagnosis of persistent arteries improves clinical interpretation and reduces the risk of improper operation during related surgical or interventional procedures. Most persistent arteries are discovered incidentally through imaging, and their imaging manifestations are characteristic. There are many reports on the imaging diagnosis of persistent arteries at home and abroad, but few on ultrasonography staging and hemodynamics. Based on the literature, this paper innovatively proposed an ultrasound diagnostic concept and staging of the persistent artery in an effort to improve the early and accurate diagnosis of the persistent artery.

对脑血管病患者的脑组织氧合情况实施床旁监测，对脑血管病的诊治及预后改善有重要价值。近红外光谱成像（near infrared spectroscopy，NIRS）作为一项新兴的脑成像技术，具有价格低廉、操作便捷、非侵入性等优点，逐渐成为脑血管病研究的焦点。本文介绍了NIRS的基本原理，探讨了NIRS在急性脑梗死早期识别、梗死后再灌注疗效评估、大面积脑梗死继发恶性脑水肿预测等方面的应用价值，预测了NIRS在大脑近皮层出血病情监测中的应用前景。此外，在蛛网膜下腔出血诊疗领域，NIRS通过动态监测脑氧饱和度，在迟发性脑缺血监测及术后功能结局预测等方面也有着较大的应用潜力。最后，本文基于NIRS的优势和不足，展望了未来适合NIRS应用的临床场景。加强NIRS在脑血管病领域的研究，将使实时评估脑血管病院前、院内的精准动态成为可能。 Bedside monitoring of cerebral oxygenation in patients with cerebrovascular diseases is of great value for the diagnosis, treatment and prognosis of cerebrovascular diseases. As a novel brain imaging technology, near infrared spectroscopy (NIRS) has the advantages of low price, good convenience and non-invasiveness. It has gradually become the focus of cerebrovascular disease research. This article introduced the basic principle of NIRS, the application of NIRS in early recognition of acute cerebral infarction, efficacy evaluation of reperfusion after infarction, and prediction of malignant cerebral edema secondary to large cerebral infarction, and also the application prospect of NIRS in monitoring the hemorrhage near cerebral cortex. For patients with subarachnoid hemorrhage, NIRS may play a great potential role in monitoring delayed cerebral ischemia and predicting postoperative functional outcome by dynamical monitoring cerebral oxygen saturation. Finally, based on the advantages and disadvantages of NIRS, we looked forward to the clinical scenarios suitable for NIRS application in the future. Further NIRS research in cerebrovascular disease will make accurate pre-hospital and in-hospital real-time dynamic assessment of cerebrovascular disease possible.

真实世界研究由于其研究结果更贴近真实世界，在临床研究领域逐渐受到关注和重视。真实世界研究不是并列于观察性研究和试验性研究的某种特定的研究设计类型，在真实世界研究的数据分析中更需要关注混杂因素和协变量的控制。正确识别混杂因素和协变量以及合理应用统计方法对其进行控制，可有效提高研究结论的准确性和真实性。本文介绍了真实世界研究中混杂因素和协变量控制的常见方法，包括分层分析、协方差分析、多因素回归、倾向性评分、疾病风险评分和工具变量分析等，并结合脑血管病的临床研究应用实例展开分析，以期为研究者理解与应用相关方法提供参考。 Abstract: Real-world studies have increasely become the focus in the field of clinical research because their findings are closer to the real world. However, real-world study is not a specific type of research design parallel with observational studies and experimental studies, and the control of confounding factors and covariates in the data analysis of real-world studies should be paid more attention. Correct identification of confounding factors/covariates and reasonable application of statistical methods can effectively improve the accuracy and authenticity of research conclusions. This article introduced the common methods of confounding factors/covariates control in real-world studies, including hierarchical analysis, analysis of covariance, multi-factor regression, propensity score, disease risk score and instrumental variable analysis, and cases analysis combined with clinical research application of cerebrovascular disease, so as to provide reference for understanding and applying the relevant methods.

真实世界研究起源于实用性临床试验，在真实临床实践中评估干预的有效性和安全性，对随机对照试验以外临床疗效评价进行补充。然而，此类研究缺乏随机化，因此对混杂偏倚的控制尤为重要。倾向性评分法对多个混杂因素/协变量进行校正，是真实世界研究控制混杂因素的重要分析方法。本文介绍匹配法、分层法、协变量校正法和逆概率加权法这4种倾向性评分法，并阐述各自的优缺点。随后结合脑血管病临床研究特点，通过研究案例重点介绍倾向性评分法在脑血管病真实世界研究中的应用。 Abstract: Real-world studies, originating from pragmatic clinical trials, evaluate the effectiveness and safety of interventions in real clinical practice, as a supplement for randomized controlled trials to evaluate the effectiveness of intervention measures in real clinical environment. However, the control of confounding factors is particularly important as this type of study lacks randomization. The propensity score method, which can adjust for multiple confounders/covariates, is an important analysis method for controlling confounders in real world studies. This article introduced four methods of propensity score and discussed their advantages and disadvantages; and introduced the application of propensity score method in the real-world research on cerebrovascular disease through case studies, combined with the characteristics of clinical research on cerebrovascular disease.

中枢胰岛素参与大脑的多种生理功能，对多种行为和代谢产生影响。中枢胰岛素抵抗的定义是脑细胞不能对胰岛素作出反应。胰岛素受体表达下调、胰岛素受体不能结合胰岛素以及胰岛素信号级联错误激活等原因都有可能导致中枢胰岛素抵抗。中枢胰岛素抵抗与脑血管病有着密切的关系。通过高胰岛素-正葡萄糖钳夹结合影像技术、经鼻给药、丝氨酸磷酸化与总磷酸化胰岛素受体底物比率和测定神经源性血浆外泌体中胰岛素受体底物1的水平及其磷酸化状态等方法可以对中枢胰岛素抵抗进行评估。探索中枢胰岛素抵抗机制与脑血管病的关系将有助于为脑血管病的治疗提供新的方向和靶点。 Abstract: Central insulin is involved in a variety of physiological functions of the brain and affects a variety of behaviors and metabolism. Central insulin resistance is defined as the inability of brain cells to respond to insulin. Central insulin resistance may be caused by down-regulation of insulin receptor expression, failure of insulin receptor to bind insulin, or incorrect activation of insulin signal cascade. There is a close relationship between central insulin resistance and cerebrovascular disease. Central insulin resistance can be assessed by hyperinsulinemic euglycemic clamp combined imaging technology, intranasal administration, ratio of serine phosphorylation to total phosphorylated insulin receptor substrates and determinating IRS-1 level and its phosphorylation status in neurogenic plasma exosomes. Exploring the relationship between central insulin resistance and cerebrovascular disease will help to provide new directions and targets for treatment of cerebrovascular diseases.

随着诊疗技术的发展，脑血管病的诊疗越来越多地需要其他相关学科的参与和合作，既往基于卒中单元为基础的合作模式需要更多的科室加入和更深入的合作方式。例如：缺血性卒中超急性期的再灌注治疗需要神经内科、神经外科、急诊科、神经重症监护科、神经介入科、放射科和康复科的配合；在卒中二级预防阶段，急性和亚急性期的卒中患者更强调营养支持和康复锻炼。融合性卒中单元作为卒中单元的升级模式，旨在促进神经病学、神经外科、康复部门的深入合作，以不同的合作模式，抓住分秒必争的契机，实施最佳临床实践，为患者争取更好的临床结果。探索脑血管病融合病房的初衷就是为了探索深入合作的融合病房模式，进一步加强再灌注治疗、二级预防、围手术期管理等卒中诊疗多环节的多科室协作，为构建适合不同医疗机构的卒中诊疗多科室联合模式提供参考。 Abstract: The development of cerebrovascular disease diagnosis and treatment technology facilitated more and more relevant disciplines mutual cooperation. Moreover, the stroke unit-based cooperation model requires further collaboration between more disciplines. For example, the reperfusion treatment in superacute stage of stroke requires the collaboration of neurology, neurosurgery, emergency, neurointensive care unit, neurointervention, radiology and rehabilitation disciplines. On the stage of stroke secondary prevention, it is emphasized on nutrition support and rehabilitation exercise in acute and subacute stroke patients. As the upgraded model of stroke unit, syncretic stroke unit is aimed to promote the in-depth cooperation of neurology, neurosurgery, rehabilitation departments with different cooperation patterns in multiple links of stroke diagnosis and treatment, to take any chance and carry out best clinical practice for better outcomes, so as to provide reference for multi-disciplines collaboration of stroke care in different medical institutions.
