Background

Intracranial sinus stenoses (ISS) or sinus occlusions (ISO) can lead to elevated intracranial venous blood pressure. Treatment strategies are advancing, but clinical decision making and the prediction of treatment success is hampered by the variable venous anatomy. We aimed to create a patient-specific computational model that allows for simulating pathologies and their influence on venous flow dynamics and pressure.

Methods

The model was created based on a stroke patient’s CT-angiography using semi-automatic threshold-based segmentation with subsequent flow modeling through computational fluid dynamics. Venous flow velocities were compared to a healthy cohort’s flow encoded magnetic resonance imaging (4D Flow MRI). Nine scenarios, including ISS and ISO at different locations, were simulated and their influence on venous pressure and blood flow was quantified.

Results

In comparison to a healthy cohort’s 4D Flow MRI, the model showed comparable venous velocities at all reference points. Unilateral transverse sinus occlusion or stenosis led to compensatory contralateral flow and elevated pressures up to 12 mmHg. Extensive ISO or bilateral transverse ISS led to markedly increased pressures > 100 mmHg.

Conclusion

Our model depicts realistic venous blood pressures and gradients and could support in identifying patients with intracranial sinus stenosis or sinus occlusions profiting from endovascular treatment strategies.
背景:颅内窦狭窄(ISS)或窦性闭塞(SO)可导致颅内静脉压升高。治疗策略正在进步,但临床决策和治疗成功的预测受到可变静脉解剖的阻碍。我们的目标是创建一个患者特定的计算模型,允许模拟病理及其对静脉血流动力学和压力的影响。方法:基于脑卒中患者的ct血管造影,采用基于半自动阈值分割的方法建立模型,随后通过计算流体动力学建立血流模型。将静脉血流速度与健康队列的血流编码磁共振成像(4D flow MRI)进行比较。模拟不同位置的ISS和ISO 9种情况,量化其对静脉压和血流的影响。结果:与健康队列的4D血流MRI相比,该模型在所有参考点显示出相当的静脉速度。单侧横窦闭塞或狭窄导致代偿性对侧血流和血压升高高达12mmhg。广泛的SO或双侧横向ISS导致血压明显升高至100 mmHg。结论:我们的模型描述了真实的静脉血压和梯度,可以支持识别颅内窦狭窄或窦闭塞的患者,并从血管内治疗策略中获益。

Objective

To systematically analyze the application effect of holistic nursing intervention based on Harmonious Nursing Theory in patients during stroke recovery period, and provide evidence-based basis for optimizing clinical nursing programs.

Methods

Patients in the stroke recovery period were divided into observation group and control group with 83 cases each by random number table method. The control group received routine nursing intervention, while the observation group received holistic nursing intervention based on Harmonious Nursing Theory. The Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Herth Hope Index (HHI), SF-36 Short-Form Health Survey, and nursing satisfaction questionnaire were used to compare the differences in negative emotions, hope level, quality of life, and satisfaction between the two groups of patients before and after intervention.

Results

After the intervention, the self-reported anxiety score of the observation group was (42.87±17.32) and the self-reported depression score was (45.28±16.67), both significantly lower than those of the control group [(51.59±15.19) and (50.51±15.52), respectively; all P<0.05]. The total score of hope level in the observation group was (40.87±6.03), which was higher than that in the control group [(34.78±5.93); P<0.05]. The scores of all 8 dimensions of health status in the observation group were higher than those in the control group (all P<0.05). The nursing satisfaction rate of the observation group was 92.77%, which was higher than 78.31% of the control group (P<0.05).

Conclusion

Implementing holistic nursing intervention based on Harmonious Nursing Theory for patients in stroke recovery period can effectively alleviate negative emotions, improve hope level and quality of life, as well as enhance nursing satisfaction, which has high clinical promotion value.

Vision loss is a risk factor for dementia, but it is unknown whether stroke-related vision impairment is linked to dementia risk in stroke survivors. This secondary analysis aimed to quantify the association between stroke-related vision impairment and time to incident dementia diagnosis, from time of stroke, using the Arthrosclerosis Risk in Communities study dataset. We included participants who sustained a non-fatal probable or definite ischemic, incident stroke captured from hospital surveillance during the study period and excluded those who were diagnosed with incident dementia prior to or less than half a year after the incident stroke. The association between stroke-related vision impairment (binary) and time from incident stroke to dementia diagnosis was analyzed using a Fine-Gray survival model to account for the competing risk of death, adjusting for age at incident stroke, stroke severity, biological sex, education and race-center. Among 787 stroke survivors, 31 % were diagnosed with dementia during the follow-up period and 19.5 % had stroke-related vision impairment. The presence of stroke-related vision impairment was not significantly associated with dementia diagnosis (HR = 1.18; 95 % CI 0.85, 1.63; p = 0.32). While results suggest that stroke-related vision impairment corresponds to a higher cumulative incidence of dementia, the association was not statistically significant.
视力丧失是痴呆症的一个危险因素,但目前尚不清楚中风相关的视力损害是否与中风幸存者患痴呆症的风险有关。这项二级分析旨在利用社区关节硬化风险研究数据集,量化卒中相关视力损害与卒中时间到痴呆诊断之间的关系。我们纳入了在研究期间从医院监测中获得的非致命性的、可能的或明确的缺血性卒中的参与者,排除了那些在卒中发生前或发生后不到半年被诊断为痴呆的参与者。使用Fine-Gray生存模型分析卒中相关视力障碍(二元)与卒中至痴呆诊断时间之间的关联,以考虑卒中发生时的年龄、卒中严重程度、生理性别、教育程度和种族中心等因素的竞争死亡风险。在787名中风幸存者中,31%在随访期间被诊断患有痴呆症,19.5%患有与中风相关的视力障碍。卒中相关视力障碍的存在与痴呆诊断无显著相关性(HR=1.18; 95% CI 0.85, 1.63; p = 0.32)。虽然研究结果表明,中风相关的视力损害与较高的痴呆累积发病率相对应,但这种关联在统计上并不显著。

Introduction

Cerebral Infarction due to Severe ADAMTS-13 Deficiency (CISAD) remains an underrecognized cause of cryptogenic stroke. Despite the absence of classic hematologic features, CISAD confers a risk of recurrent ischemic events if not promptly identified and treated. Increased clinical awareness is essential to prompt appropriate laboratory testing and reduce stroke recurrence.

Methods

We conducted a retrospective cohort study at Montefiore Medical Center to identify patients with ischemic stroke and severe ADAMTS-13 deficiency from January 2017 to June 2025. Of 235 screened patients, 197 had an acute ischemic stroke. 9 met final inclusion criteria for CISAD: confirmed ischemic stroke, severe ADAMTS-13 deficiency at index event, and absence of microangiopathic hemolytic anemia (MAHA). Clinical, hematologic, and imaging characteristics were analyzed descriptively in the final cohort.

Results

Of 9 patients, 7 were female. Mean age was 51.3 years. Platelet counts were normal in 6 of 9 cases. 4 of 9 patients had large vessel occlusions. 3 patients had multifocal infarcts. 8 of 9 patients met Embolic Stroke of Undetermined Source (ESUS) criteria before ADAMTS-13 testing. 1 had three ESUS events before ADAMTS-13 deficiency was identified. The remaining 6 patients had an established history of thrombotic thrombocytopenic purpura (TTP) and presented with recurrent strokes and severe ADAMTS-13 deficiency. 2 patients had multiple strokes with severe ADAMTS-13 deficiency. All patients were treated with steroids, therapeutic plasma-exchange (TPE), and/or Rituximab.

Conclusion

CISAD may present without hematologic abnormalities and should be considered as a rare cause of stroke. Early ADAMTS-13 activity and inhibitor testing in select patients may allow timely diagnosis, treatment, and prevention of recurrence.
由于严重ADAMTS-13缺乏症引起的脑梗死(CISAD)仍然是一种未被充分认识的隐源性卒中原因。尽管没有典型的血液学特征,如果不及时发现和治疗,CISAD会有复发性缺血性事件的风险。提高临床意识对于促进适当的实验室检测和减少卒中复发至关重要。方法:我们在Montefiore医学中心进行了一项回顾性队列研究,以确定2017年1月至2025年6月期间缺血性卒中和严重ADAMTS-13缺乏症患者。在235名接受筛查的患者中,197名患有急性缺血性中风。9例符合CISAD的最终纳入标准:确诊缺血性卒中,指数事件时严重ADAMTS-13缺乏,无微血管病溶血性贫血(MAHA)。在最后的队列中,对临床、血液学和影像学特征进行描述性分析。结果:9例患者中,女性7例。平均年龄51.3岁。9例患者中6例血小板计数正常。9例患者中4例有大血管闭塞。3例出现多灶性梗死。在ADAMTS-13检测前,9例患者中有8例符合来历不明的栓塞性卒中(ESUS)标准。在确定ADAMTS-13缺陷之前,我有三次ESUS事件。其余6例患者有血栓性血小板减少性紫癜(TTP)病史,并伴有卒中复发和严重的ADAMTS-13缺乏。2例多发卒中伴严重ADAMTS-13缺乏症。所有患者均接受类固醇、治疗性血浆置换(TPE)和/或利妥昔单抗治疗。结论:CISAD可能没有血液学异常,应考虑为一种罕见的中风原因。在选定的患者中进行早期ADAMTS-13活性和抑制剂测试可能有助于及时诊断、治疗和预防复发。

Background and Purpose

External counterpulsation (ECP) noninvasively augments cerebral blood flow in patients with ischemic stroke. We investigated whether the cerebral augmentation index (CAI), measured by transcranial Doppler (TCD) during ECP, could predict the functional outcome of ischemic stroke.

Methods

Patients with unilateral ischemic stroke in the anterior circulation territory were enrolled within 7 days of symptom onset. Mean flow velocities in both middle cerebral arteries (MCA) were monitored by TCD before, during and immediately after ECP. CAI was defined as the percentage increase in MCA mean flow velocity during ECP relative to baseline. TCD data from the ipsilateral and contralateral sides of the cerebral infarct were analyzed and compared between patients with good outcomes (modified Rankin Scale (mRS) 0-2) and those with poor outcomes (mRS 3-6) at 3 months post-stroke.

Results

Among 200 recruited patients (mean age, 64.5 ± 8.9 years; 86.5 % men), functional outcomes were good in 148 (74.0 %) and poor in 52 (26.0 %). Admission NIH Stroke Scale, history of ischemic heart disease, and CAI on both the ipsilateral and contralateral sides differed significantly between the two groups (all P < 0.05). In multivariate analysis, NIH Stroke Scale (OR, 1.677 [95 % CI, 1.363-2.064]; P < 0.001), ipsilateral CAI (OR, 1.282 [95 % CI, 1.148-1.646]; P = 0.012), and contralateral CAI (OR, 1.104 [95 % CI, 1.002-1.234]; P = 0.038) independently predicted poor functional outcomes.

Conclusion

CAI, a cerebral hemodynamic index measured over the MCA on either the ipsilateral or contralateral side of an acute cerebral infarct, may predict unfavorable stroke outcomes.
背景与目的:体外反搏(ECP)无创增加缺血性脑卒中患者的脑血流量。我们研究了ECP期间经颅多普勒(TCD)测量的脑增强指数(CAI)是否可以预测缺血性卒中的功能结局。方法:选取症状出现后7天内单侧前循环区域缺血性脑卒中患者。在ECP前、中、后分别用TCD监测两脑中动脉(MCA)平均血流速度。CAI定义为ECP期间MCA平均流速相对于基线增加的百分比。分析脑梗死同侧和对侧TCD数据,并比较卒中后3个月预后良好(改良Rankin量表(mRS) 0-2)和预后较差(mRS 3-6)的患者。结果:纳入的200例患者(平均年龄64.5±8.9岁,男性86.5%)中,148例(74.0%)功能预后良好,52例(26.0%)功能预后差。两组入院时NIH卒中量表、缺血性心脏病史、同侧和对侧CAI差异均有统计学意义(P < 0.05)。在多变量分析中,NIH卒中量表(OR, 1.677 [95% CI, 1.363-2.064]; P < 0.001)、同侧CAI (OR, 1.282 [95% CI, 1.148-1.646]; P=0.012)和对侧CAI (OR, 1.104 [95% CI, 1.002-1.234]; P=0.038)独立预测功能不良结局。结论:CAI是在急性脑梗死的同侧或对侧的MCA上测量的脑血流动力学指数,可以预测不良的脑卒中结局。

Introduction

Dementia has been strongly linked with cardiovascular disease, but the relationships between cardiovascular disease and brain health at subclinical stages have not been fully explored. We investigated the associations between subclinical cardiac dysfunction, defined by cardiac biomarkers and echocardiography, and novel neurobiomarkers associated with the brain injury in older adults.

Methods

We included 962 participants from the Cardiovascular Health Study who had no history of stroke, transient ischemic attack, atrial fibrillation, heart failure, or myocardial infarction. We analyzed cross-sectional associations using linear regression. Outcomes variables were serum neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP), two markers of subclinical brain injury. Exposure variables were serum N-terminal pro-brain-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) and subclinical cardiac measures including echocardiographic left atrial reservoir strain, left ventricular average longitudinal strain, early diastolic strain rate of the left ventricle, decreased left ventricular ejection fraction, average E/e’, percent predicted left ventricular mass, and left atrial diameter.

Results

Among 844 participants with serum biomarkers, hs-cTnT was significantly associated with NfL (β = 1.881, 95 % CI: (0.729, 3.032), p = 0.001), and this association remained significant even after mutual adjustment for NT-proBNP (β = 1.781, 95 % CI: (0.626, 2.937), p = 0.003). NT-proBNP was also associated with NfL (β = 1.170, 95 % CI: (0.047, 2.293), p = 0.041), although this association was slightly attenuated and not statistically significant after adjustment for hs-cTnT (β = 1.004, 95 % CI: (-0.119, 2.126), p = 0.08). There were no significant associations observed for either circulating marker with GFAP, nor were echocardiographic variables associated with NfL or GFAP.

Conclusions

In older adults without clinically identified cardiovascular disease, subclinical cardiac dysfunction identified through hs-cTnT and, to a lesser extent, NT-proBNP, was associated with higher levels of NfL, a marker of brain injury. This novel insight suggests that even subclinical cardiac disease is linked to brain health.
导读:痴呆症与心血管疾病密切相关,但在亚临床阶段,心血管疾病与大脑健康之间的关系尚未得到充分探讨。我们研究了由心脏生物标志物和超声心动图定义的亚临床心功能障碍与老年人脑损伤相关的新型神经生物标志物之间的关系。方法:我们纳入了962名来自心血管健康研究的参与者,他们没有中风、短暂性脑缺血发作、心房颤动、心力衰竭或心肌梗死的病史。我们使用线性回归分析了横断面关联。结果变量为血清神经丝轻链(NfL)和胶质纤维酸性蛋白(GFAP),这是亚临床脑损伤的两个标志物。暴露变量为血清n端脑前型利钠肽(NT-proBNP)和高敏心肌肌钙蛋白T (hs-cTnT),亚临床心脏指标包括超声心动图左房储液池应变、左室平均纵向应变、左室早期舒张应变率、左室射血分数下降、平均E/ E′、预测左室质量百分比和左房内径。结果:在844名有血清生物标志物的参与者中,hs-cTnT与NfL显著相关(β=1.881, 95% CI: (0.729, 3.032), p=0.001),即使在NT-proBNP相互调整后,这种关联仍然显著(β=1.781, 95% CI: (0.626, 2.937), p=0.003)。NT-proBNP也与NfL相关(β=1.170, 95% CI: (0.047, 2.293), p=0.041),尽管在调整hs-cTnT后,这种关联略有减弱,且无统计学意义(β=1.004, 95% CI: (-0.119, 2.126), p=0.08)。循环标志物与GFAP均无显著相关性,超声心动图变量与NfL或GFAP均无显著相关性。结论:在没有临床心血管疾病的老年人中,通过hs-cTnT和NT-proBNP(在较小程度上)发现的亚临床心功能障碍与较高水平的NfL(脑损伤的标志)相关。这一新颖的见解表明,即使是亚临床心脏病也与大脑健康有关。

背景:按摩可以有效缓解脑瘫(CP)的症状,但其在脑瘫中的具体机制尚不清楚。脑白质损伤是CP大鼠缺氧缺血(HI)的主要后果。本研究旨在探讨按摩促进骨髓间充质干细胞(BMSCs-Exo)通过趋化因子轴向脑迁移的潜力,以减轻CP大鼠脑白质损伤。方法:48只大鼠随机分为假手术组、模型组、按摩组和抑制组。在3日龄大鼠幼鼠中诱导HI损伤,并通过翻正反射评估和脑血流成像证实。按摩组自出生后第5天起每日进行按摩治疗,连续28 d。抑制组给予CXCR4抑制剂(AMD3100),其余组给予生理盐水。治疗后2周和4周分别进行行为评估。采用小动物活体成像监测BMSCs-Exo的归巢效率,采用光声成像无创测量脑氧饱和度。用尼氏染色评价神经元形态,并用免疫荧光与CXCR4/SDF-1共标记少突胶质细胞。采用PCR检测骨髓、血清和脑白质中SDF-1/CXCR4的表达。体外实验包括在缺氧和低糖条件下将骨髓间充质干细胞与少突胶质细胞共培养。细胞组包括正常对照组、DMSO对照组、按摩组、按摩 + GW4869组。用CCK-8测定骨髓间充质干细胞和少突胶质细胞的活力。此外,免疫荧光染色显示少突胶质细胞中的外泌体。结果:HI损伤使翻正反射潜伏期延长,脑血流量减少。按摩干预可以改善血流量,增加BMSCs-Exo的脑归一化,并增强肢体功能,在4周后尤为明显。尼氏染色和免疫荧光组织学分析显示,按摩与神经元损伤减轻和少突胶质细胞中SDF-1/CXCR4表达上调相一致。在HI后最初降低的SDF-1/CXCR4水平通过按摩恢复,CXCR4抑制剂显着消除按摩的治疗效果。CCK-8实验表明,按摩与促进骨髓间充质干细胞和少突胶质细胞的活力有关,在外泌体抑制下,这种活力减弱。此外,与DMSO对照组相比,按摩组少突胶质细胞对外泌体的摄取能力更强。结论:按摩与脑瘫患者运动功能增强和白质恢复有关,可能通过SDF-1/CXCR4轴、增加BMSCs-Exo向大脑的归家以及增强少突胶质细胞附着等机制。

Background

For stroke patients with history of possible Direct Acting Oral Anticoagulant use, clinicians must make treatment decisions without knowledge of whether the patient is therapeutically anticoagulated. A urine-based point-of-care test might help guide these emergency decisions.

Methods

We prospectively enrolled patients with suspected recent factor-Xa-inhibitor (Xai) use being evaluated for acute stroke therapy in an urban teaching hospital. We obtained the urine test and plasma anti-Xa level in parallel with usual clinical management; the treating clinician did not use test results for decision-making but recorded treatment they would have given had they known the urine test was accurate. The primary outcome was feasibility. Secondary outcomes were accuracy of the urine test at plasma anti-Xa level >30 ng/mL and consequent change in clinical management.

Results

Twenty-one patients were enrolled over 1 year. The urine test was successfully carried out in all patients, median 59 minutes after Emergency Department arrival. Sensitivity and specificity for the urine test to detect threshold anti-Xa activity were 100 % and 87.5 %. Of 20 patients with ischemic stroke, none of whom were treated with thrombolytics, 6 had a negative test which would have resulted in treatment of 4 (66 %).

Conclusion

A urine point-of-care test for Xai activity is feasible, accurate, and would likely result in treatment of stroke patients currently excluded from thrombolysis.

Background

Although socio-economic status (SES) is a recognised risk factor for stroke, few studies have examined stroke incidence by SES in Australia. We investigated the incidence of first-ever stroke by SES using state-wide record linkage data.

Methods

This retrospective cohort study used linked Tasmanian Admitted Patient Care and the Death Registry data. Fatal and non-fatal strokes 2007–2020 were identified using ICD-10 codes (8-year clearance period) to identify first-ever strokes 2015–2020. SES was from Index of Relative Socio-economic Advantage and Disadvantage by quintiles (low, low medium, medium, medium high, high). Covariates included sex, age, and remoteness. Population denominators (2016 Australian population) were used to calculate crude and age-standardised incidence rates. Poisson regression models estimated adjusted incidence rate ratios (IRR) for first-ever stroke by SES group.

Results

We identified 4901 first-ever stroke cases (63% ischaemic stroke, mean [SD] age 75 [14] years, 52% female). Ischaemic heart disease (12% lowest vs 7% highest SES), diabetes (26% lowest vs 18% highest SES), and hypertension (48% lowest vs 39% highest SES) were significantly different by SES. The age-standardised rate was 134/100,000 persons (95% CI 130, 138). Compared to the high SES group, the IRR for first-ever stroke was 1.20 (95% CI 1.09, 1.33) for the low medium SES group and 1.33 (95% CI 1.22, 1.46) for the low SES group, adjusting for age, sex, stroke incident year, and remoteness.

Conclusions

Lower SES groups had a higher incidence of first-ever stroke. Public health and primary care strategies targeting stroke risk factors in these groups may reduce stroke incidence.
背景:虽然社会经济地位(SES)是卒中的一个公认的危险因素,但在澳大利亚很少有研究通过社会经济地位来检查卒中的发病率。我们调查了首次中风的发病率SES使用全国范围内的记录联动数据。方法:这项回顾性队列研究使用了塔斯马尼亚住院病人护理和死亡登记的相关数据。使用ICD-10代码(8年清除期)确定2007-2020年的致命性和非致命性中风,以确定2015-2020年的首次中风。SES为相对社会经济优势和劣势指数,分五位数(低、中低、中、中高、高)。协变量包括性别、年龄和偏远地区。人口分母(2016年澳大利亚人口)用于计算粗发病率和年龄标准化发病率。泊松回归模型估计了SES组首次卒中的调整发病率比(IRR)。结果:我们确定了4901例首次卒中病例(63%为缺血性卒中,平均[SD]年龄75岁,52%为女性)。缺血性心脏病(12%最低SES vs 7%最高SES)、糖尿病(26%最低SES vs 18%最高SES)和高血压(48%最低SES vs 39%最高SES)因SES而有显著差异。年龄标准化率为134/100,000人(95% CI 130,138)。与高经济地位组相比,中低经济地位组首次卒中的IRR为1.20 (95% CI 1.09, 1.33),低经济地位组为1.33 (95% CI 1.22, 1.46),调整了年龄、性别、卒中发生年份和偏远地区。结论:社会经济地位较低的组首次卒中的发生率较高。针对这些人群卒中危险因素的公共卫生和初级保健策略可能会降低卒中发病率。

Background

Ischemic stroke often results in persistent motor impairments due to disrupted cortical excitability in the lesional hemisphere. Acupuncture and repetitive transcranial magnetic stimulation (rTMS) have each shown potential in enhancing neural plasticity. Their combination may provide synergistic effects, but no meta-analysis has specifically examined objective neurophysiological outcomes.

Objective

To evaluate the efficacy of acupuncture combined with rTMS in improving cortical excitability after ischemic stroke using neurophysiological indicators.

Methods

A systematic review and meta-analysis were conducted according to PRISMA 2020 guidelines. PubMed, Embase, Web of Science, and Cochrane Library were searched up to June 30, 2025. Randomized controlled trials (RCTs) comparing acupuncture+rTMS with rTMS alone, acupuncture alone, sham stimulation, or conventional rehabilitation, and reporting at least one cortical excitability indicator—motor evoked potential (MEP) amplitude or latency, resting motor threshold (RMT), or central motor conduction time (CMCT)—were included. Risk of bias was assessed with the Cochrane tool, and trial sequential analysis (TSA) was performed.

Results

Twelve RCTs involving 1,012 patients were included. Compared with controls, acupuncture+rTMS significantly increased MEP amplitude (SMD = 1.08, 95 % CI: 0.90–1.26), decreased MEP latency (SMD = –0.90, 95 % CI:1.13 to –0.66), reduced RMT (SMD = –0.76, 95 % CI:0.99 to –0.53), and shortened CMCT (SMD = –0.83, 95 % CI:1.14 to –0.52), all with low heterogeneity (I2 = 0–20.4 %). TSA showed that the cumulative Z-curve crossed the monitoring boundary but the required information size (RIS = 1,268) was not reached, indicating that while the current evidence is promising, further adequately powered randomized controlled trials are still required.

Conclusions

Acupuncture combined with rTMS significantly enhances cortical excitability after ischemic stroke, supporting its value in neurorehabilitation. Larger, standardized trials are warranted to confirm these findings and evaluate long-term benefits.
背景:缺血性中风通常会导致持续性运动障碍,这是由于病变半球皮层兴奋性的破坏。针刺和重复经颅磁刺激(rTMS)均显示出增强神经可塑性的潜力。它们的组合可能提供协同效应,但没有荟萃分析专门检查客观神经生理结果。目的:应用神经生理指标评价针刺联合rTMS对缺血性脑卒中后皮质兴奋性的改善作用。方法:根据PRISMA 2020指南进行系统评价和荟萃分析。PubMed、Embase、Web of Science和Cochrane Library的检索截止日期为2025年6月30日。随机对照试验(rct)将针灸+rTMS与单独rTMS、单独针灸、假刺激或常规康复进行比较,并报告至少一项皮质兴奋性指标——运动诱发电位(MEP)振幅或潜伏期、静息运动阈值(RMT)或中枢运动传导时间(CMCT)。采用Cochrane工具评估偏倚风险,并进行试验序列分析(TSA)。结果:纳入12项随机对照试验,共1012例患者。与控制相比,针灸+ rTMS显著增加议员振幅(SMD = 1.08,95%置信区间CI: 0.90 - -1.26),减少议员延迟(SMD = -0.90,95%置信区间CI: -1.13 - -0.66),降低了RMT (SMD = -0.76,95%置信区间CI: -0.99 - -0.53),并缩短CMCT (SMD = -0.83,95%置信区间CI: -1.14 - -0.52),所有较低的异质性(I2 = 0 - 20.4%)。TSA显示,累积z曲线跨越了监测边界,但没有达到所需的信息大小(RIS = 1,268),这表明尽管目前的证据是有希望的,但仍需要进一步的充分有力的随机对照试验。结论:针刺联合rTMS可显著增强缺血性脑卒中后皮层兴奋性,支持其在神经康复中的应用价值。有必要进行更大规模的标准化试验来证实这些发现并评估长期效益。
