| 1 | 小胶质细胞对星形胶质细胞的免疫和神经保护功能的调节作用(英文)显示文摘在中枢神经系统中,小胶质细胞和星形胶质细胞对神经元的发育、功能维持及细胞存活具有重要的作用。但在炎症反应过程中,星形胶质细胞增生的作用及其对神经元的影响目前并不十分清楚。因此,本研究对不同种类的细胞进行培养,给予细菌脂多糖(lipopolysaccharide,LPS)刺激,观察各种细胞的反应。结果显示,星形胶质细胞可以减轻炎症反应的神经元毒性,提示星形胶质细胞增生主要具有神经保护作用。如果去掉上清液中由星形胶质细胞分泌的胶质细胞源性神经营养因子(glial cell line-derived neurotrophic factor,GDNF),这种神经保护作用显著降低。为了研究星形胶质细胞的免疫功能,本研究培养了高浓度的星形胶质细胞,并发现LPS不能诱导肿瘤坏死因子(tumor necrosis factor,TNF)-α及诱导型一氧化氮合酶(inducible nitric oxide synthase,iN OS)/一氧化氮(nitric oxide,NO)(iN OS/NO)释放。但如果在培养的高浓度星形胶质细胞中增加0.5%~1%的小胶质细胞,则可以诱导TNF-α及iN OS/NO的释放。这提示小胶质细胞和星形胶质细胞间的相互作用对于LPS诱导星形胶质细胞释放前炎症因子及GDNF是必须的。我们还发现,小胶质细胞释放的TNF-α可以通过旁分泌作用调节星形胶质细胞的神经保护功能。综上所述,本研究结果提示星形胶质细胞可能不会直接被LPS激活,而是通过与小胶质细胞相互作用被激活,释放神经营养因子,减少因炎症反应激活的小胶质细胞释放的毒性物质对神经元的损害作用。 | Chen SH Oyarzabal EA Sung YF Chu CH Wang Q Chen SL Lu RB Hong JS 唐颖馨 | 2015 | 神经损伤与功能重建2015,10,1: | 9 |

| 4 | Experimental Study on Deoxidization of Bariumand Barium Alloy显示文摘Based on the review of latest papers related to the application of barium alloy, the deoxidizationeffects of barium and barium alloy, and the dynamic characteristics of molten bath have beensystematically studied by means of the convection free bath, natural convection bath, air andvacuum induction melting experiments. It was found that both the total oxygen content andsoluble oxygen content in molten bath decreased rapidly. The results obtained provided practicaland theoretical basis for further synthetic applications of barium alloy in metallurgical industry. | Shi, YF Chen, BP Fu, J El Gammal, T | 1999 | Journal of Materials Science & Technology1999,15,5: | 4 |
| 5 | 集体主义价值观在冲突管理中所起的作用——基于一个管理实验的分析显示文摘学者们认为集体主义价值观有利于避免组织中冲突,以及有利于冲突的良性演化。本研究采用实验方法,招募80位志愿者参与实验研究。实验结果显示,相比个人主义,集体主义对建立合作目标更有帮助。他们也很自信他们可以一起工作,一起作决策,以提问表达他们对反对意见的理解,接受这些意见的合理之处,以及整合立场来产生一个整合的决策。实验结果挑战集体主义价值观可避免冲突的传统理论,支持最近的一些观念即牢固的人际关系可在决策过程中促进反对意见的有效讨论。 | 吴培冠 Dean Tjosvold Nancy YF Chen | 2010 | 上海管理科学2010,32,3: | 3 |
