This study presents a scientometric analysis of the intersection between rehabilitation science and artificial intelligence (AI) technologies, using data from the Web of Science (WOS) database from 2002 to 2022. The analysis employed a comprehensive search query with key AI-related terms, focusing on a wide range of publications in rehabilitation science. Utilizing the Citespace tool, the study visualizes and quantifies the relationships between key terms, identifies research trends, and assesses the impact of AI technologies in rehabilitation science. Findings reveal a significant increase in AI-related research in this field, particularly from 2017 onwards, peaking in 2021. The United States has been a leading contributor, followed by countries like England, Australia, Germany, and Canada. Major institutional contributions come from Harvard University and the Pennsylvania Commonwealth System of Higher Education, among others. A keyword co-occurrence network constructed through Citespace identifies nine distinct hot topics and various research frontiers, highlighting evolving focus areas within the field. Burst analysis of keywords indicates a shift from performance and injury-related research to an increasing emphasis on AI and deep learning in recent years. The study also predicts the potential impact of papers, spotlighting works by Kunze KN and others as significantly influencing future research directions. Additionally, it examines the evolution of knowledge bases in AI-related rehabilitation science research, revealing a multidisciplinary core that includes neurology, rehabilitation, and ophthalmology, extending to complementary fields such as medicine and social sciences. This scientometric analysis provides a comprehensive overview of AI's application in rehabilitation science, offering insights into its evolution, impact, and emerging trends over the past two decades. The findings suggest strategic directions for future research, policy-making, and interdisciplinary collaboration in rehabilitation science and AI.

This research emphasises the value of physical training for table tennis players, particularly as ball speed and spin rate decline and emphasises how important intensity quality is to the game. Chinese table tennis players' dual identities place greater demands on the general growth of their learning and training as a crucial component of talent development preparation. Athletes' general quality, competitive level, and ability to avoid sports injuries are all improved by scientific and focused physical training. In order to achieve the functions of intelligent camera, multi-angle broadcasting, and 3D scene reproduction, this study combines the physical training model of artificial intelligence. This gives the audience a more engaging and in-depth viewing experience. More feature extraction of the match footage is made possible by deep learning and convolutional neural networks when combined with large-scale video data, greatly enhancing the match information for viewers. The experimental findings demonstrate that the accuracy of table tennis human technical movement recognition reaches 98.88 % based on the enhanced AM-Softmax classification algorithm.

这项研究强调了体能训练对乒乓球运动员的价值,尤其是在球速和旋转率下降的情况下,并强调了强度质量对比赛的重要性。中国乒乓球运动员的双重身份对其学习和训练的总体成长提出了更高的要求,这是人才培养准备工作的重要组成部分。运动员的综合素质、竞技水平、避免运动损伤的能力都是通过科学的、有针对性的体能训练来提高的。为了实现智能摄像、多角度转播、三维场景再现等功能,本研究结合了人工智能的体能训练模式。这给观众带来了更具吸引力和深度的观看体验。通过深度学习和卷积神经网络,结合大规模视频数据,可以对比赛画面进行更多的特征提取,大大增强了观众的比赛信息。实验结果表明,基于增强型 AM-Softmax 分类算法的乒乓球人体技术动作识别准确率达到 98.88%。

Th1/Th2 cytokines in early peripheral blood of patients with multiple injuries and its predictive value for SIRS: A bioinformatic analysis 多发性损伤患者早期外周血中的 Th1/Th2 细胞因子及其对 SIRS 的预测价值:生物信息学分析
IF 2.5 4区 医学 Q3 BIOCHEMICAL RESEARCH METHODS Pub Date : 2024-08-01 DOI: 10.1016/j.slast.2024.100150

This study aims to evaluate the changes in helper T lymphocyte (Th)1/Th2 factor levels in peripheral blood of patients with severe multiple injuries and their prognostic value for nosocomial infection using bioinformatic analysis. The experimental group consisted of 180 patients with numerous injuries admitted to our hospital between January 2021 and June 2023, with 80 healthy volunteers serving as controls. Th1 cytokines (interleukin-2 and interferon-γ) and Th2 cytokines (IL-4 and IL-10) were evaluated 48 hours after admission using enzyme-linked immunosorbent assays. The experimental group was separated into two groups: those with systemic inflammatory response syndrome (SIRS) and those without SIRS, for cytokine analysis and SIRS incidence. Furthermore, the study examined Th1 and Th2 cytokine levels in trauma patients in various body locations within the experimental group. A receiver operating characteristic (ROC) curve analysis was performed to determine the predictive value of Th1/Th2 cytokines for SIRS incidence. The experimental group had lower IL-2 and IFN-γ levels compared to the control group, but greater levels of IL-4 and IL-10. There were no significant variations in Th1 and Th2 cytokine levels across the experimental groups. Patients with SIRS had lower levels of IL-2 and IFN-γ but greater levels of IL-4 and IL-10 compared to those without SIRS. Combined cytokine levels have a better predictive value for SIRS than individual cytokines alone. In conclusion, individuals with severe multiple injuries had a change from Th1 to Th2 cytokine profiles, which was most evident in those with SIRS. The combined cytokine levels had a substantial predictive value for SIRS incidence in this patient cohort.

本研究旨在通过生物信息学分析,评估严重多发伤患者外周血中辅助T淋巴细胞(Th)1/Th2因子水平的变化及其对非医院感染的预后价值。实验组由我院 2021 年 1 月至 2023 年 6 月期间收治的 180 名多发性损伤患者组成,对照组为 80 名健康志愿者。入院 48 小时后,使用酶联免疫吸附试验评估 Th1 细胞因子(白细胞介素-2 和干扰素-γ)和 Th2 细胞因子(IL-4 和 IL-10)。实验组被分为两组:有全身炎症反应综合征(SIRS)和无全身炎症反应综合征,用于细胞因子分析和 SIRS 发生率。此外,研究还检测了实验组中创伤患者不同身体部位的 Th1 和 Th2 细胞因子水平。为了确定 Th1/Th2 细胞因子对 SIRS 发生率的预测价值,研究人员进行了接收者操作特征(ROC)曲线分析。与对照组相比,实验组的 IL-2 和 IFN-γ 水平较低,但 IL-4 和 IL-10 水平较高。各实验组的 Th1 和 Th2 细胞因子水平无明显差异。与无 SIRS 的患者相比,SIRS 患者的 IL-2 和 IFN-γ 水平较低,但 IL-4 和 IL-10 水平较高。与单个细胞因子相比,综合细胞因子水平对 SIRS 有更好的预测价值。总之,严重多发性损伤患者的细胞因子谱从 Th1 型转变为 Th2 型,这在 SIRS 患者中最为明显。综合细胞因子水平对该组患者的 SIRS 发生率有很大的预测价值。

Most of the biopharmaceuticals that are currently on the market are expressed using the Chinese Hamster Ovary (CHO) cell lines. However, the production yield of these biopharmaceuticals is affected due to CHO cellular heterogeneity and challenges in adaptability during the bioreactor scale-up stage. In this communication, we report the protocol for the miniaturized directed evolution process for CHO cells. The results of the directed evolution process would guide adapting the CHO cell line before bioreactor scale-up. With our approach, we have established the protocol that can be used to streamline superior CHO cell lines for biopharmaceutical production which would be the first of its kind in Africa. Our directed evolution protocol includes a method for a low-cost multiplex directed evolution process that can be used on CHO cells using 20 stressors in 8 concentrations and provides stable trial results for the scale-up process. Using our process, we can provide a simple consumable kit that manufacturers can use for the CHO cell phenotype stability test before the scale-up process. With our approach, we would further develop a platform that can streamline superior CHO cell lines for biopharmaceutical production. This approach would be the first of its kind in South Africa/ Africa.

Abnormal genes and pathways that drive muscle contracture from brachial plexus injuries: Towards machine learning approach 驱动臂丛神经损伤肌肉挛缩的异常基因和途径:机器学习方法
IF 2.5 4区 医学 Q3 BIOCHEMICAL RESEARCH METHODS Pub Date : 2024-08-01 DOI: 10.1016/j.slast.2024.100166

In order to clarify the pathways closely linked to denervated muscle contracture, this work uses IoMT-enabled healthcare stratergies to examine changes in gene expression patterns inside atrophic muscles following brachial plexus damage. The gene expression Omnibus (GEO) database searching was used to locate the dataset GSE137606, which is connected to brachial plexus injuries. Strict criteria (|logFC|≥2 & adj.p < 0.05) were used to extract differentially expressed genes (DEGs). To identify dysregulated activities and pathways in denervated muscles, gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, and Gene Set Enrichment Analysis (GSEA) were used. Hub genes were found using Cytoscape software's algorithms, which took into account parameters like as proximity, degree, and MNC. Their expression, enriched pathways, and correlations were then examined. The results showed that 316 DEGs were predominantly concentrated in muscle-related processes such as tissue formation and contraction pathways. Of these, 297 DEGs were highly expressed in denervated muscles, whereas 19 DEGs were weakly expressed. GSEA showed improvements in the contraction of striated and skeletal muscles. In addition, it was shown that in denervated muscles, Myod1, Myog, Myh7, Myl2, Tnnt2, and Tnni1 were elevated hub genes with enriched pathways such adrenergic signaling and tight junction. These results point to possible therapeutic targets for denervated muscular contracture, including Myod1, Myog, Myh7, Myl2, Tnnt2, and Tnni1. This highlights treatment options for this ailment which enhances the mental state of patient.

Nanoengineered therapeutic strategies targeting SNHG1 for mitigating microglial ischemia-reperfusion injury implications for hypoxic-ischemic encephalopathy 靶向 SNHG1 的纳米工程治疗策略减轻小胶质细胞缺血再灌注损伤对缺氧缺血性脑病的影响
IF 2.5 4区 医学 Q3 BIOCHEMICAL RESEARCH METHODS Pub Date : 2024-08-01 DOI: 10.1016/j.slast.2024.100167

The purpose of this work is to investigate the function of SNHG1, a long non-coding RNA implicated in disease progression, apoptosis, and proliferation, in order to solve the problem of hypoxic-ischemic encephalopathy (HIE) in newborn care. We investigated the impact of overexpressing SNHG1 on hypoxia-induced apoptosis and studied its expression in BV2 microglial cells under hypoxic circumstances. As a result of modifying YY1 expression, SNHG1′s overexpression prevents apoptosis, as our data demonstrate that it is considerably downregulated under hypoxia. We demonstrate that SNHG1 might potentially reduce microglial ischemia-reperfusion damage by using sophisticated nanoengineering drug delivery technologies to target it. This provides encouraging information for the therapy of ischemic epilepsy.

SNHG1是一种与疾病进展、细胞凋亡和增殖有关的长非编码RNA,本研究旨在研究SNHG1的功能,以解决新生儿缺氧缺血性脑病(HIE)的治疗问题。我们研究了过表达 SNHG1 对缺氧诱导的细胞凋亡的影响,并研究了缺氧环境下 SNHG1 在 BV2 小胶质细胞中的表达。由于改变了 YY1 的表达,SNHG1 的过表达可防止细胞凋亡,因为我们的数据表明,在缺氧条件下,SNHG1 的表达会显著下调。我们证明,利用先进的纳米工程给药技术靶向 SNHG1,有可能减轻小胶质细胞缺血再灌注损伤。这为缺血性癫痫的治疗提供了令人鼓舞的信息。

This study aims to diagnose Rotator Cuff Tears (RCT) and classify the severity of RCT in patients with Osteoporosis (OP) through the analysis of shoulder joint anteroposterior (AP) X-ray-based localized proximal humeral bone mineral density (BMD) measurements and clinical information based on machine learning (ML) models.

Methods

A retrospective cohort of 89 patients was analyzed, including 63 with both OP and RCT (OPRCT) and 26 with OP only. The study analyzed a series of shoulder radiographs from April 2021 to April 2023. Grayscale values were measured after plotting ROIs based on AP X-rays of shoulder joint. Five kinds of ML models were developed and compared based on their performance in predicting the occurrence and severity of RCT from ROIs' greyscale values and clinical information (age, gender, advantage side, lumbar BMD, and acromion morphology (AM)). Further analysis using SHAP values illustrated the significant impact of selected features on model predictions.

Results

R1-6 had a positive correlation with BMD respectively. The nine variables, including greyscale R1-6, age, BMD, and AM, were used in the prediction models. The RF model was determined to be superior in effectively diagnosing RCT in OP patients, with high AUC scores of 0.998, 0.889, and 0.95 in the training, validation, and testing sets, respectively. SHAP values revealed that the most influential factors on the diagnostic outcomes were the grayscale values of all cancellous bones in ROIs. A column-line graph prediction model based on nine variables was constructed, and DCA curves indicated that RCT prediction in OP patients was favored based on this model. Furthermore, the RF model was also the most superior in predicting the types of RCT within the OPRCT group, with an accuracy of 86.364% and 73.684% in the training and test sets, respectively. SHAP values indicated that the most significant factor affecting the predictive outcomes was the AM, followed by the grayscale values of the greater tubercle, among others.

Conclusions

ML models, particularly the RF algorithm, show significant promise in diagnosing RCT occurrence and severity in OP patients using conventional shoulder X-rays based on the nine variables. This method presents a cost-effective, accessible, and non-invasive diagnostic strategy that has the potential to substantially enhance the early detection and management of RCT in OP patient population.

本研究旨在通过分析基于肩关节前后位(AP)X 光片的局部肱骨近端骨矿密度(BMD)测量值和基于机器学习(ML)模型的临床信息,诊断肩袖撕裂(RCT)并对骨质疏松症(OP)患者的 RCT 严重程度进行分类。研究分析了2021年4月至2023年4月期间的一系列肩部X光片。根据肩关节的 AP X 光片绘制 ROI 后测量灰度值。根据 ROI 的灰度值和临床信息(年龄、性别、优势侧、腰椎 BMD 和肩峰形态 (AM))建立了五种 ML 模型,并比较了这些模型在预测 RCT 的发生和严重程度方面的性能。使用 SHAP 值进行的进一步分析表明了所选特征对模型预测的重要影响。结果R1-6 分别与 BMD 呈正相关。预测模型中使用了九个变量,包括灰度 R1-6、年龄、BMD 和 AM。结果表明,RF 模型在有效诊断 OP 患者的 RCT 方面更具优势,其训练集、验证集和测试集的 AUC 分别高达 0.998、0.889 和 0.95。SHAP 值显示,对诊断结果影响最大的因素是 ROI 中所有松质骨的灰度值。基于九个变量构建的柱状线图预测模型和 DCA 曲线表明,基于该模型对 OP 患者的 RCT 预测更有利。此外,RF模型在预测OPRCT组中的RCT类型方面也最为出色,在训练集和测试集中的准确率分别为86.364%和73.684%。SHAP值表明,影响预测结果的最重要因素是AM,其次是大结节的灰度值等。结论ML模型,尤其是RF算法,在根据九个变量使用常规肩部X光片诊断OP患者RCT的发生和严重程度方面显示出了巨大的潜力。这种方法是一种经济、方便、无创的诊断策略,有望大大提高对 OP 患者的 RCT 早期检测和管理水平。

Coronary microcirculation dysfunction (CMD) is one of the main causes of cardiovascular disease. Traditional treatment methods lack specificity, making it difficult to fully consider the differences in patient conditions and achieve effective treatment and intervention. The complexity and diversity of CMD require more standardized diagnosis and treatment plans to clarify the best treatment strategy and long-term outcomes. The existing treatment measures mainly focus on symptom management, including medication treatment, lifestyle intervention, and psychological therapy. However, the efficacy of these methods is not consistent for all patients, and the long-term efficacy is not yet clear. GSEA is a bioinformatics method used to interpret gene expression data, particularly for identifying the enrichment of predefined gene sets in gene expression data. In order to achieve personalized treatment and improve the quality and effectiveness of interventions, this article combined GSEA (Gene Set Enrichment Analysis) technology to conduct in-depth research on potential drug targets and their interaction networks in coronary microcirculation dysfunctions. This article first utilized the Coremine medical database, GeneCards, and DrugBank public databases to collect gene data. Then, filtering methods were used to preprocess the data, and GSEA was used to analyze the preprocessed gene expression data to identify and calculate pathways and enrichment scores related to CMD. Finally, protein sequence features were extracted through the calculation of autocorrelation features. To verify the effectiveness of GSEA, this article conducted experimental analysis from four aspects: precision, receiver operating characteristic (ROC) curve, correlation, and potential drug targets, and compared them with Gene Regulatory Networks (GRN) and Random Forest (RF) methods. The results showed that compared to the GRN and RF methods, the average precision of GSEA improved by 0.11. The conclusion indicated that GSEA helped identify and explore potential drug targets and their interaction networks, providing new ideas for personalized quality of CMD.

冠状动脉微循环功能障碍(CMD)是导致心血管疾病的主要原因之一。传统的治疗方法缺乏特异性,难以充分考虑患者病情的差异,实现有效的治疗和干预。CMD 的复杂性和多样性要求更规范的诊断和治疗方案,以明确最佳治疗策略和长期疗效。现有的治疗措施主要集中于症状管理,包括药物治疗、生活方式干预和心理治疗。然而,这些方法对所有患者的疗效并不一致,长期疗效也尚不明确。GSEA是一种用于解读基因表达数据的生物信息学方法,尤其适用于识别基因表达数据中预定义基因组的富集情况。为了实现个性化治疗,提高干预的质量和效果,本文结合GSEA(基因组富集分析)技术,对冠状动脉微循环功能障碍的潜在药物靶点及其相互作用网络进行了深入研究。本文首先利用Coremine医学数据库、GeneCards和DrugBank公共数据库收集基因数据。然后,使用过滤方法对数据进行预处理,并使用GSEA对预处理后的基因表达数据进行分析,以识别和计算与CMD相关的通路和富集得分。最后,通过计算自相关特征提取蛋白质序列特征。为了验证GSEA的有效性,本文从精确度、接收者操作特征曲线(ROC)、相关性和潜在药物靶点四个方面进行了实验分析,并与基因调控网络(GRN)和随机森林(RF)方法进行了比较。结果表明,与GRN和RF方法相比,GSEA的平均精确度提高了0.11。结论表明,GSEA有助于识别和探索潜在的药物靶点及其相互作用网络,为CMD的个性化质量提供了新思路。

Lymphoma is a malignant tumor originating from the lymphopoietic system, which can affect all tissues and organs of the body. Lymphoma is highly heterogeneous and the therapeutic effect varies greatly. Different pathological types and stages of lymphoma differ greatly in terms of treatment intensity and prognosis. Early diagnosis of lymphoma is very important to improve the prognosis of patients. Therefore, this work explored the diagnostic value of independent and combined detection of computed tomography (CT), ultrasound, and positron emission tomography - computed tomography (PET-CT) for lymphoma. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) in the PET-CT and combination groups were greatly higher than those in the CT and ultrasound groups, showing obvious differences (P < 0.05). The area under curve (AUC) values in the CT group, ultrasound group, PET-CT group, and combination group were 0.632 (P = 0.032), 0.614 (P = 0.025), 0.793 (P = 0.002), and 0.859 (P = 0.001), respectively, exhibiting observable differences (P < 0.05). the sensitivity and specificity of PET/CT for lymphoma were higher than those of CT and ultrasound, which can clearly show the early mild results of lymphatic lymphoma. Therefore, the combined diagnosis of lymphatic lymphoma with PET/CT was of high clinical value.

淋巴瘤是一种起源于淋巴造血系统的恶性肿瘤,可影响人体的所有组织和器官。淋巴瘤具有高度异质性,治疗效果差异很大。不同病理类型和分期的淋巴瘤在治疗强度和预后方面差异很大。淋巴瘤的早期诊断对改善患者的预后非常重要。因此,本研究探讨了计算机断层扫描(CT)、超声和正电子发射断层扫描-计算机断层扫描(PET-CT)独立检测和联合检测对淋巴瘤的诊断价值。PET-CT组和联合组的敏感性、特异性、阳性预测值(PPV)和阴性预测值(NPV)均大大高于CT组和超声组,差异明显(P<0.05)。CT组、B超组、PET-CT组和联合组的曲线下面积(AUC)值分别为0.632(P=0.032)、0.614(P=0.025)、0.793(P=0.002)和0.859(P=0.001),表现出明显的差异(P<0.05)。PET/CT对淋巴瘤的敏感性和特异性均高于CT和B超,可明确显示淋巴淋巴瘤的早期轻度结果。因此,PET/CT联合诊断淋巴淋巴瘤具有较高的临床价值。

This study probed the importance of computed tomography perfusion (CTP) on assessing collateral circulation and prognosis in patients with acute anterior circulation large vessel occlusion (AAC-LVO) after endovascular therapy (EVT). Retrospective analysis was performed on the case data of 124 AAC-LVO patients who achieved EVT in the First People's Hospital of Lianyungang. All patients received computed tomography (CT) examination. Based on the multi-phase computed tomography angiography (mCTA) score, patients were separated into poor collateral circulation group and good collateral circulation group. Based on modified Rankin scale (mRS) score, patients were separated into good prognosis group and poor prognosis group. The receiver operating characteristic (ROC) curve was used to measure the efficacy of CTP parameters in predicting good collateral circulation or good prognosis. Correlation between CTP parameters with mCTA collateral and 90-day mRS circulation score was analyzed using the Spearman correlation analysis. The age and admission national Institutes of Health stroke scale (NIHSS) scores of the good collateral circulation group were lower than the poor collateral circulation group, and low perfusion area volume with Tmax > 6 s (VTmax>6 s), infarct core area volume (VCBF<30 %)and hypoperfusion intensity ratio (HIR) were also lower. The mCTA collateral cycle score was negatively related to VTmax>6 s, VCBF<30 % and HIR. The area under the curve (AUC) values of VTmax>6 s and VCBF<30 % and HIR for predicting good collateral circulation were 0.763, 0.884 and 0.842, respectively, which suggested that perfusion parameters VTmax>6 s, VCBF<30 % and HIR could effectively indicate the status of patients’ collateral circulation. Relative to the poor prognosis group, patients in the good prognosis group possessed lower admission NIHSS score, younger age, smaller final infarct volume, lower HIR, VCBF<30 %, VTmax>6 s, Alberta Stroke Program Early CT(ASPECT) score, and higher mCTA score. Spearman correlation analysis unveiled that ASPECT score, mCTA score and 90-day mRS were negatively correlated. The final infarct volume, perfusion parameters HIR and VCBF<30 % were positively correlated with 90-day mRS. ROC analysis showed that all variates had good prognostic value for acute anterior circulation great vessel occlusion patients, while VCBF<30 % and HIR had high diagnostic value for prognosis. To sum up, CTP can provide a comprehensive imaging assessment of the collateral circulation of patients with AAC-LVO and has a higher predictive value for the prognosis assessment of patients with EVT in terms of VCBF<30 %, HIR score and mCTA collateral circulation score.

本研究探讨了计算机断层扫描灌注(CTP)对评估急性前循环大血管闭塞(AAC-LVO)患者血管内治疗(EVT)后侧支循环和预后的重要性。该研究对连云港市第一人民医院124例接受EVT治疗的AAC-LVO患者的病例数据进行了回顾性分析。所有患者均接受了计算机断层扫描(CT)检查。根据多相计算机断层扫描血管造影(mCTA)评分,将患者分为侧支循环不良组和侧支循环良好组。根据改良兰金量表(mRS)评分,将患者分为预后良好组和预后不良组。采用接收者操作特征曲线(ROC)来衡量 CTP 参数在预测侧支循环良好或预后良好方面的有效性。采用斯皮尔曼相关分析法分析了CTP参数与mCTA侧支和90天mRS循环评分之间的相关性。侧支循环良好组的年龄和入院时美国国立卫生研究院卒中量表(NIHSS)评分低于侧支循环不良组,Tmax>6 s的低灌注面积体积(VTmax>6s)、梗死核心面积体积(VCBF)和低灌注强度比(HIR)也低于侧支循环不良组。mCTA 侧支循环评分与 VTmax>6 s、VCBF 和 HIR 呈负相关。预测侧支循环良好的 VTmax>6 s、VCBF 和 HIR 的曲线下面积(AUC)值分别为 0.763、0.884 和 0.842,这表明灌注参数 VTmax>6 s、VCBF 和 HIR 能有效显示患者的侧支循环状况。与预后不良组相比,预后良好组患者入院时的NIHSS评分较低、年龄较小、最终梗死体积较小、HIR、VCBF、VTmax>6s、Alberta Stroke Program Early CT(ASPECT)评分较低、mCTA评分较高。斯皮尔曼相关分析表明,ASPECT评分、mCTA评分和90天mRS呈负相关。最终梗死体积、灌注参数 HIR 和 VCBF 与 90 天 mRS 呈正相关。ROC分析表明,所有变量对急性前循环大血管闭塞患者均有良好的预后价值,而VCBF和HIR对预后有较高的诊断价值。综上所述,CTP可对AAC-LVO患者的侧支循环进行全面的影像学评估,而且与VCBF、HIR评分和mCTA侧支循环评分相比,CTP对EVT患者的预后评估具有更高的预测价值。
