| 1 | Mesenchymal stem cell-derived exosomes promote neurogenesis and cognitive function recovery in a mouse model of Alzheimer’s disease显示文摘Studies have shown that mesenchymal stem cell-derived exosomes can enhance neural plasticity and improve cognitive impairment.The purpose of this study was to investigate the effects of mesenchymal stem cell-derived exosomes on neurogenesis and cognitive capacity in a mouse model of Alzheimer’s disease.Alzheimer’s disease mouse models were established by injection of beta amyloid 1?42 aggregates into dentate gyrus bilaterally.Morris water maze and novel object recognition tests were performed to evaluate mouse cognitive deficits at 14 and 28 days after administration.Afterwards,neurogenesis in the subventricular zone was determined by immunofluorescence using doublecortin and PSA-NCAM antibodies.Results showed that mesenchymal stem cells-derived exosomes stimulated neurogenesis in the subventricular zone and alleviated beta amyloid 1?42-induced cognitive impairment,and these effects are similar to those shown in the mesenchymal stem cells.These findings provide evidence to validate the possibility of developing cell-free therapeutic strategies for Alzheimer’s disease.All procedures and experiments were approved by Institutional Animal Care and Use Committee(CICUAL)(approval No.CICUAL 2016-011)on April 25,2016. | Edwin E.

| 4 | p63基因在肺癌组织中的表达显示文摘目的 研究肺鳞状细胞癌、腺癌、大细胞肺癌、小细胞肺癌以及淋巴结或肺内转移性肿瘤标本组织中p63基因的mRNA转录因子和蛋白表达水平,探讨p63基因表达与其定位在3q 27-q29区域改变的关系。方法 采用cDNA微阵列技术同时检测72例不同病理组织学类型的原发性肺癌(包括鳞状细胞癌、腺癌、大细胞癌、小细胞癌)和肺癌肺内转移及淋巴结转移灶内的p63基因mRNA水平。另外,利用组织芯片技术构建150例原发性肺癌石蜡包埋标本组织芯片,采用免疫组织化学LSAB法检测p63基因蛋白表达情况。同时应用比较基因组杂交(CGH)技术对70例原发性肺癌标本进行了3号染色体长臂改变的分析。结果 p63mRNA转录因子在肺鳞状细胞癌标本表达明显增强,与腺癌、大细胞癌、小细胞癌相比增多10倍以上。肺癌转移灶内p63基因mRNA表达水平明显高于其相对应的原发性灶,差异有统计学意义(P<0.001)。免疫组织化学染色结果显示:肺鳞状细胞癌阳性表达率为94.64%;腺癌是1.79%;4例大细胞肺癌中2例为阳性染色;但所有小细胞肺癌标本免疫组织化学染色均为阴性。pT1分期肺癌的p63基因蛋白表达阳性率与pT2分期肺癌相比有统计学差异(P<0.05)。比较基因组杂交结果发现:肺鳞状细胞癌3号染色体长臂27-29区域有显著的扩增,腺癌表现为缺失。鳞状细胞癌p63基因的? | 余永伟 Mitchell E Garber KarstenSchlüns ManuelaPacyna-Gengelbach IverPetersen | 2004 | 中华病理学杂志2004,33,4: | 7 |
| 5 | 妊娠期高血压疾病对远期心血管病的影响显示文摘对妇女妊娠期高血压疾病(hypertensive disorder of pregnancy,HDP)史的研究,可能有助于改善动脉粥样硬化性心血管病的风险评估。但是,有HDP既往史的中年无症状妇女在未来患心血管病的风险仍未知。该研究旨在探讨有或无HDP既往史的中年女性心血管病的远期发病率。纳入标准:在前瞻性、观察性英国生物资料库中,纳入40~69岁并至少有一活产的英国妇女,对其中一亚组妇女进行了无创性动脉硬度测量。 | 周卫(译) 叶鹏(摘、审校) Honigberg MC Zekavat SM Aragam K Klarin D Bhatt DL Scott NS Peloso GM Natarajan P | 2020 | 中华高血压杂志2020,28,2: | 6 |
