阿尔兹海默症患者的语义记忆损伤:表现、理论及展望     

方燕红  尹观海 《宜春学院学报》2020,(2):116-120

图片命名、范畴流畅性等神经心理学测验表明,阿尔兹海默症(AD)患者普遍存在语义记忆的损伤,并随着病程的发展表现出进行性与弥散性特点。AD患者语义记忆的损伤既可能由语义知识的存储障碍造成,也可能由语义知识的提取障碍引发,还可能由存储与提取的双重损伤造成。未来研究应开发出对早期AD检测更为敏感的语义记忆测验,并采用横向与纵向多种研究技术与手段,考虑不同语言文化背景下AD患者语义损伤的情况,以综合分析AD患者语义记忆损伤的实质及其发展趋势。  相似文献   

烟碱对豚鼠和兔乳头状肌动作电位的影响     

王庆山  尹京湘 《河北北方学院学报(医学版)》1989,(2)

烟碱对豚鼠及兔乳头状肌电活动的RP,APA和Vmax无明显影响;但对其复极时程则因浓度不同,而呈延长或缩短双相效应。高浓度烟碱(604μmol/L使APD_(85),APD_(90)和ERP分别延长27.3,26.0及26.1％;而低浓度(0.6μmol/L)使三者分别缩短49.6,40.0及27.6％。烟碱对慢电位的影响,表明可能高浓度烟碱促进Ca~(2 )内流;低浓度则抑制Ca~(2 )内流。  相似文献

坏习惯损伤宫颈     

马帅 《科学与文化》2006,(12):47-47

目前，女性宫颈炎患病率很高，如不及时治疗很可能发展为宫颈癌。在日常生活中，一些女性的不良习惯会让身体受到细菌的侵扰，容易造成感染，进而生成各种妇科疾病。有害习惯1：长期使用护垫。许多女性都以为，使用护垫可避免阴部和内裤的直接接触，有助于保持阴部环境清洁。这种想法是很错误的，因为长期使用护垫，容易使阴部透气不良而致感染。所以，最好只在月经将净或月经将至的短期内用护垫。  相似文献   

Cell therapy in congestive heart failure   总被引：5，自引：0，他引：5  

Tao ZW  Li LG 《Journal of Zhejiang University. Science. B》2007,8(9):647-660

Congestive heart failure （CHF） has emerged as a major worldwide epidemic and its main causes seem to be the aging of the population and the survival of patients with post-myocardial infarction. Cardiomyocyte dropout （necrosis and apoptosis） plays a critical role in the progress of CHF; thus treatment of CHF by exogenous cell implantation will be a promising medical approach. In the acute phase of cardiac damage cardiac stem cells （CSCs） within the heart divide symmetrically and/or asymmetrically in response to the change of heart homeostasis, and at the same time homing of bone marrow stem cells （BMCs） to injured area is thought to occur, which not only reconstitutes CSC population to normal levels but also repairs the heart by differentiation into cardiac tissue. So far, basic studies by using potential sources such as BMCs and CSCs to treat animat CHF have shown improved ventricular remodelling and heart function. Recently, however, a few of randomized, double-blind, placebo-controlled clinical trials demonstrated mixed results in heart failure with BMC therapy during acute myocardial infarction.  相似文献   

Effect of a distal protection device on epicardial blood flow and myocardial perfusion in primary percutaneous coronary intervention   总被引：2，自引：0，他引：2  

Zhou BQ  Tahk SJ 《Journal of Zhejiang University. Science. B》2007,8(8):575-579

Objective: The beneficial effect of percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) has been well established, but there is the problem of no-reflow phenomenon which is an adverse prognostic factor in primary PCI. In the present study the effect of a distal protection device (PercuSurge GuardWire; GW) on epicardial blood flow and myocardial perfusion was evaluated. Methods and Results: Patients with AMI were randomly divided into 2 groups, the GW and the control groups. The GW group included 52 patients with AMI who underwent primary PCI with GW protection and the control group included 60 patients who underwent primary PCI without GW protection. Epicardial blood flow in the infarct-related artery (IRA) and myocardial perfusion were evaluated according to the thrombolysis in myocardial infarction (TIMI) flow grade and the myocardial blush grade (MBG). We found TIMI score of 3 was obtained significantly more frequently in the GW group (96%) than in the control group (80%). The MBG score of 3 was obtained also significantly greater in the GW group (65%) than in the control group (33%). Conclusion: Primary PCI with GW protection can significantly improve epicardial blood flow and myocardial perfusion.  相似文献
