Many evidences suggested that hyperglycemia caused excess free fatty acids, the loss of endothelium-derived nitric oxide, insulin resistance, the prothrombotic state, endothelial dysfunction, the abnormal release of endothelial vasoactivators,vascular smooth muscle dysfunction, oxidative stress, and the downregulation of mi Rs participated in vessel generation and recovery as well as the balance of endotheliocytes. In turn, these abnormalities, mainly via phosphatidylinositol 3 kinase, mitogen-activated protein kinase, polyol, hexosamine, protein kinase C activation, and increased generation of advanced glycosylation end products pathway, play an important role in inducing diabetic CVD complication. A deeper comprehension of pathogenesis producing diabetic CVD could offer base for developing new therapeutic ways preventing diabetic CVD complications, therefore, in the paper we mainly reviewed present information about the possible pathogenesis of diabetic CVD complication.展开更多

文摘目的 探讨脑小血管病(CSVD)患者近期皮质下小梗死与认知功能的相关性。方法 回顾性连续纳入2018年2月―2022年9月就诊于北京大学第一医院神经内科经头部MRI诊断的CSVD患者,收集一般人口学资料和临床资料,使用简易精神状态量表(MMSE)、蒙特利尔认知评估量表(MoCA)评估认知功能,根据磁共振DWI分为近期皮质下小梗死(RSSI)组和非RSSI组,统计RSSI的部位和数目。比较两组患者的一般人口学资料、临床资料、认知功能,分析RSSI影像学特征与认知功能的关系。结果 共纳入CSVD患者181例,RSSI组91例,非RSSI组90例。RSSI组与非RSSI组相比,BMI高[(25.43±3.53)kg/m^(2) vs(24.27±3.33)kg/m^(2),t=2.228, P=0.027],收缩压高[(145.3±16.2)mmHg vs(139.6±20.2)mmHg,t=2.013,P=0.046],MoCA总分较低[22(18.8,26) vs 24(21,27),Z=-1.980,P=0.048],视空间与执行能力[3(2,4) vs 4(3,5),Z=-2.756,P=0.006]、语言[2(2,3) vs 2(1,2), Z=-2.020,P=0.043]、抽象[2(1,2) vs 2(1,2)分,Z=-2.052,P=0.04]得分均较低,差异均具有显著性统计学意义(P<0.05)。RSSI基底节梗死组与非RSSI组相比,MoCA总分较低[21(17,23) vs 24(21,27),Z=-2.018,P=0.044],视空间与执行[3(1.5,3.5) vs 4(3,5),Z=-2.601,P=0.009]得分较低,RSSI脑干梗死组与非RSSI组相比,视空间与执行[3(2,4) vs 4(3,5),Z=-2.325,P=0.020]、语言[2(1,2) vs 2(2,3),Z=-2.338,P=0.019]得分较低,差异具有显著性统计学意义。结论 CSVD患者中RSSI可导致认知功能障碍,与RSSI梗死部位相关,RSSI不同梗死部位导致不同的认知损害模式。预防RSSI发生,对于预防CSVD相关认知功能障碍具有重要意义。
文摘目的探讨水蛭治疗脑小血管病(Cerebral Small Vessel Disease,CSVD)所致神经功能障碍患者的临床疗效。方法选取2020年10月—2023年6月广西壮族自治区民族医院神经内科收治的120例CSVD导致认知功能障碍患者为研究对象,以随机数表法分为对照组(n=60,常规西药内科基础治疗)和观察组(n=60,在对照组基础上增加中药水蛭治疗)。分别于治疗前、治疗2周及治疗3个月后观察两组患者的神经功能障碍评分和血清胱抑素C、同型半胱氨酸、高敏C反应蛋白指标水平。结果与治疗前相比,两组治疗2周、治疗3个月后的神经功能障碍评分以及血清胱抑素C、同型半胱氨酸、高敏C反应蛋白指标水平均明显下降,且观察组治疗3个月后下降幅度更大,差异有统计学意义(P均<0.05)。观察组治疗的总有效率(86.67%)高于对照组(71.67%),差异有统计学意义(χ^(2)=4.093,P<0.05)。结论水蛭能有效改善CSVD所致的神经功能缺损,同时能降低患者血清胱抑素C、同型半胱氨酸、高敏C反应蛋白指标水平。
文摘脑小血管病(cerebral small vessel disease,CSVD)是一组临床、影像、病理综合征,主要累及颅内小血管,起病隐匿。CSVD与卒中、认知下降、情感障碍、步态异常及尿便失禁密切相关,给家庭和社会带来沉重的疾病负担和经济负担。但CSVD的致病机制仍不明确,临床诊断标准不统一,临床诊疗和试验研究面临重大挑战。本文旨在汇总当前CSVD的可能病因、发病机制和临床诊疗研究的进展及局限性,展望CSVD未来可能的临床研究方向。
文摘脑小血管病(cerebral small vessel disease,CSVD)是引起人群认知功能障碍最重要的原因之一,随着我国人口老龄化趋势的加重及医学影像技术的发展,CSVD的发病率呈逐年上升趋势,其所引起的认知功能障碍也越来越受到关注。因脑小血管病起病隐匿、进展缓慢、早期无明显临床表现,出现症状时已进入认知功能障碍的中晚期或者已经形成痴呆,往往带给患者不能逆转的损伤及沉重的医疗负担。本文就不同影像学类型脑小血管病及其MRI总负荷对认知功能的影响进行综述,进一步了解CSVD与认知功能的关系,为CSVD所致认知功能障碍的识别和预防提供帮助。
