急性缺血性脑卒中(AIS)是一种严重影响人类健康相关的疾病,其拥有高发病率和高死亡率,并与吸烟、高脂饮食等不良生活习惯相关,人工智能(AI)比如机器学习(ML)和深度学习(DL),可以实现从临床及辅助检查尤其是成像学检查中提取特征数据,经过算法处理,得出可信结果。近几年AI更多地应用于医院系统的工作中,并成为临床工作及科研项目有力的帮手。本文全面综述了AI预测急性缺血性脑卒中(AIS)患者在经过血管内治疗,尤其是经过血栓切除术治疗后的预后情况,从而实现精准有效的临床管理和护理决策。此外,本文还批判性地评估了现有研究的局限性,并且指出了新的研究方向,最终目标是提高AIS患者的生存率。Acute ischemic stroke (AIS) is a serious human health-related disease that is characterized by elevated morbidity and mortality rates. It is often linked to detrimental lifestyle behaviors, including smoking and high-fat dietary intake. The advent of artificial intelligence (AI), encompassing machine learning (ML) and deep learning (DL) methodologies, facilitates the extraction and analysis of feature data derived from clinical and ancillary assessments, particularly imaging studies. These data are processed through sophisticated algorithms to yield reliable outcomes. In recent years, AI has been increasingly integrated into hospital systems, emerging as a formidable tool in both clinical practice and research initiatives. This paper presents a comprehensive analysis of AI applications in predicting the prognosis of acute ischemic stroke (AIS) patients following endovascular interventions, with a particular focus on thrombectomy procedures. The objective is to enhance the accuracy and efficacy of clinical management and care decision-making processes. Furthermore, the study critically examines the limitations inherent in current research and identifies prospective avenues for future investigation, ultimately aiming to improve the survival outcomes of AIS patients.
在缺血性卒中的多种风险原因中,高脂血症特别是高胆固醇血症始终占有着很关键的地位,通过降低血浆中胆固醇特别是低密度脂蛋白胆固醇的水平,可以很有效地减少缺血性卒中发生的风险,这一观点已是世界神经科专家的普遍共识。他汀类药物是缺血性卒中二级预防的基石,被广泛应用于临床,然而,他汀类药物也有其自身的局限性。首先,如果他汀类药物剂量增加一倍,其降脂效果仅增加6%,这使得许多患者仅靠他汀类药物很难达到LDL-C目标。其次,有些患者不能耐受他汀类药物,这一现象在接受大剂量他汀类药物治疗的中国患者中尤为明显。近几年新上市的新型降脂药物–前蛋白转化酶枯草溶菌素9 (proprotein convertase subtilisin/kexin type 9, PCSK9)抑制剂则为缺血性卒中的治疗提供了新的策略。Among the myriad risk factors for ischemic stroke, hyperlipidemia, particularly hypercholesterolemia, consistently holds a pivotal role. The reduction of plasma cholesterol levels, notably low-density lipoprotein cholesterol (LDL-C), has been recognized as an effective strategy to mitigate the risk of ischemic stroke. This perspective has garnered widespread acceptance among neurology experts globally. Statins, as the mainstay of secondary prevention for ischemic stroke, are extensively utilized in clinical settings. However, statins are not without their inherent limitations. Firstly, the lipid-lowering efficacy of statins plateaus with increased dosage;doubling the dose results in a mere 6% increase in cholesterol reduction, making it challenging for many patients to achieve their LDL-C targets with statin monotherapy. Secondly, statin intolerance is not uncommon, with a pronounced incidence observed among Chinese patients undergoing high-dose statin therapy. In this context, the advent of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, a novel class of lipid-lowering agents, offers a promising alternative for the management of ischemic stroke, presenting a new therapeutic horizon in the field.
1例以腹泻为主要表现的肠气囊肿症(pneumatosis cystoides intestinalis, PCI)患者,患者既往糖尿病20余年,一直在规律服用“阿卡波糖”降糖治疗,完善腹部影像学及内镜检查后明确诊断为肠气囊肿症。采用调整降糖方案、高压氧疗2次/天(共5天)、抑酸保护胃黏膜、调节肠道菌群等支持治疗后患者腹泻、腹痛好转。半年后返院复查肠镜未见异常。肠气囊肿症是临床上一种少见的疾病,其临床表现多样,无特异性,为提高临床医生对本病的认识水平,笔者总结了1例以腹泻为主要表现的肠气囊肿症的诊治经过,现报道如下。A patient with diarrhea as the main manifestation of pneumatosis cystoides intestinalis (PCI), who has had diabetes for more than 20 years, has been taking acarbose as hypoglycemic therapy regularly. She was diagnosed with pneumatosis cystoides intestinalis after abdominal imaging and endoscopic examination. The patient’s diarrhea and abdominal pain were improved after treatment with adjusted hypoglycemic regimen, hyperbaric oxygen therapy twice a day (5 days in total), acid inhibition to protect gastric mucosa, and regulation of intestinal flora. Six months later, she returned to the hospital and rechecked the colonoscopy. Pneumatosis cystoides intestinalis is a rare disease in the clinic, and its clinical manifestations are diverse and non-specific. In order to improve the understanding level of clinicians, the author summarized the diagnosis and treatment of 1 case of pneumatosis cystoides intestinalis with diarrhea as the main manifestation, and reported as follows.
心源性栓塞性卒中(cardioembolic stroke, CES)约占据缺血性卒中20%,与其他类型的缺血性卒中相比,CES的病情更重、预后更差、复发率更高,同时治疗方案也存在差异,因此准确识别CES具有重要意义。然而,既往检查手段的限制和对该疾病的认识不足导致CES的诊断率偏低。近年来,随着心率监测技术、超声检查,影像技术等CES相关诊断技术的发展,临床对CES的识别能力显著提升。本文将从心脏以及颅脑相关影像学检查、辅助诊断人工智能技术、生物标记物、及临床量表评估心源性卒中相关评分等方面综述CES诊断技术最新的研究进展。Cardioembolic stroke (CES), accounting for approximately 20% of ischemic strokes, is characterized by more severe clinical manifestations, poorer prognosis, higher recurrence rates, and distinct therapeutic strategies compared to other ischemic stroke subtypes. Therefore, the accurate identification of CES is of great significance. However, historical limitations in diagnostic tools and insufficient understanding of the disease have contributed to suboptimal CES detection rates. In recent years, with the development of diagnostic technologies related to cardioembolic stroke (CES), such as heart rate monitoring, ultrasound examinations, and imaging techniques, the clinical ability to identify CES has significantly improved. This paper will review the latest research progress in CES diagnostic technologies from several aspects, including cardiac and cerebral imaging examinations, auxiliary diagnostic artificial intelligence technologies, biomarkers, and clinical scale assessments related to cardioembolic stroke scores.
过敏性紫癜(Henoch-Schönlein purpura, HSP)又称为IgA血管炎,是由IgA免疫复合物沉积介导的全身性小血管炎。HSP以儿童最常见,成人较为少见。临床上以皮肤紫癜最多见,可伴有关节、胃肠道及肾脏等各系统症状。当腹部症状先于紫癜出现时,易被缺乏相关经验的临床医生误诊为急腹症、急性阑尾炎、消化道出血等疾病。现报道1例以腹部症状为主的成人混合型HSP,目的在于提高临床医生对HSP的诊治水平,避免延误患者的诊治。Henoch-Schönlein purpura (HSP), also known as IgA vasculitis, is a systemic small vasculitis mediated by IgA immune complex deposition. HSP is most common in children and less common in adults. The most common clinical skin purpura, can be accompanied by joint, gastrointestinal and kidney and other system symptoms. When the abdominal symptoms appear before purpura, it is easy to be misdiagnosed as acute abdomen, acute appendicitis, gastrointestinal bleeding and other diseases by clinicians who lack relevant experience. A case of adult mixed HSP with abdominal symptoms was reported in order to improve the diagnosis and treatment of HSP by clinicians and avoid delay in diagnosis and treatment.
