《再写刘海粟》多角度展示——刘海粟的壮阔艺术人生

正我一生追求真、善、美,一生致力于美术教育事业,一生艰苦创新。——刘海粟2016年8月18日,刘海粟美术馆新馆正式在上海开馆迎客,《再写刘海粟》大展同日开幕。今年恰逢刘海粟诞辰120周年。他17岁就在上海创办了中国第一所专门美术学校;在生命的最后阶段,他将自己毕生创作的主要作品和收藏的珍品古画全部无偿捐献给了国家。此次《再写刘海粟》大展序厅为刘海粟十上黄山的装置艺术。展览分为"走向后印象"、"兴学·欧游"、"开启中国气     

英国科学家用骨髓干细胞培育出了人体心脏瓣膜组织

据2007年4月4日《参考消息》援引法新社伦敦2007年4月2日电，英国研究人员宣布他们已经从骨髓干细胞中培养出了一种“尚未发育成熟的新型瓣膜组织”，这种组织的作用原理与人体心脏瓣膜完全一致。这一成果有望使移植用心脏瓣膜替代物在几年内诞生。     

EGFP基因转染骨髓间充质干细胞的实验研究

目的:探讨外源性EGFP基因转染修饰兔骨髓间充质干细胞(m esenchymal stem cells,MSCs)的可行性。方法:用增强型荧光绿色蛋白(enhanced green fluorescent protein,EGFP)作为报告基因,以脂质体法转染骨髓间充质干细胞,观察转染结果、表达情况及对靶细胞活力的影响。结果:经荧光显微镜下观察证实:成功地对骨髓间充质干细胞实现了基因转染。结论:兔骨髓间充质干细胞能够在体外适宜的条件下进行长期培养;骨髓间充质干细胞可直接作为基因靶细胞,建立稳定表达EGFP的骨髓间充质干细胞系具有可行性,为进一步做标记的MSCs细胞的移植研究奠定基础。     

Infusion of nonmyeloablative bone marrow alleviates acute rejection reaction in liver allotransplantation

Objective: To study the effect and implication of nonmyeloablative donor specific bone marrow (DSBM) infusion on the immunoreaction of liver allotransplantation. Methods: Orthotopic liver transplantation model was used in this study. Groups were set as follows: Group Ⅰ, syngeneic control (Wistar-to-Wistar); Group Ⅱ, acute rejection (SD-to-Wistar); Group Ⅲ, acute rejection treated with cyclosporine A (CsA) by intramuscular injection (SD-to-Wistar CsA); Group Ⅳ, bone marrow infusion at 7 d pretransplantation followed by short-term CsA treatment (SD-to-Wistar DSBM); Another group of short-term CsA treatment preoperatively without bone marrow infusion was also set as control. General characteristics and survival time were observed.Histological grades of rejection were determined by pathological examination. IL-2 and IFN-γ level in peripheral blood and donor liver were detected respectively by Enzyme-Linked Immuno-Sorbent Assay (ELISA) and Western blot. Chimerism of donor cells was measured by PCR for a male-specific marker (Y-chromosome-specific sequence, Sry). Results: No signs of rejection were found in Group Ⅰ. Acute rejection occurred in both Group Ⅱ and the short-term CsA treated group. All the recipients died at (9～15)d posttransplantation with a median survival time of (10.7±0.5) d and (11.2±2.4) d, respectively. Only mild rejection could be seen in Group Ⅲ. In Group Ⅳ, 4 out of 6 recipients had long-term survival (＞100 d), the histological grade of rejection was significantly lower than that of Group Ⅱ, so did the expression level of IL-2 and IFN-γ in both peripheral blood and grafted liver.Y-chromosome-specific sequence (Sry) of male SD rats could be detected in the bone marrow, spleen and thymus of female recipients at 15 d after bone marrow infusion. Conclusion: Mild preconditioning nonmyeloablative donor specific bone marrow infusion can enhance chimerism formation in recipients, alleviate the rejection of liver allotransplantation and prolong survival of liver allotransplantation.

血常规报告中异常细胞少检和漏检的探讨

对2834例患者骨髓检查时的血细胞分类结果和该患者的静脉血白细胞分类结果进行比对,以骨髓检查时的血细胞分类结果为金标准。静脉血白细胞分类异常细胞漏检标本658例,占14.41%。其中异常细胞小于4%的标本444例;异常细胞在4%⁸%之间的标本163例;异常细胞大于8%的标本51例。在两种标本均检出异常细胞的459例标本中,白细胞分类低于骨髓检查的分类共198例标本,占6.99%,说明存在少见和漏检现象。两种标本细胞分类百分比为27%和41%,P<0.01,具有统计学差异。     

沉酿，为有暗香来——《跨越海峡的生命桥》研课心路

《跨越海峡的生命桥》是人教版四年级上册中的一篇讲读课文,讲述了台湾同胞冒着生命危险为大陆青年小钱捐赠骨髓,用爱心架起了一座跨越海峡两岸的生命桥的感人故事。文章浅显易懂,行文流畅,两岸间的血脉紊睛浓郁而温馨。设计这节课,我没有在环节上过多地雕琢,主要针对四年级学生的特点,在语言文字的理解与领悟上下工夫。

"不吃鱼皮和鸡皮的孩子,长大没衣服穿。""耳屎掉到嘴里,会再也说不了话,出不了声儿。""吃羊蝎子里的白色骨髓,会变成小傻子。""生吃花生会长大龅牙。""骗妈妈的孩子长不高。"……面对这么多威胁,我们能健康长大,多艰难啊!     

在荒草野冢间遗失的碎心——石评梅散文创作悲剧气质的归因分析

在石评梅青春年华之际写下的散文里,没有理想与憧憬,激情与浪漫,更多的是遍尝人生苦难的苍凉和超逸,历尽沧桑的幽深和哀叹.石评梅创作之所以会表现出这种透彻骨髓的悲剧气质,其原因有三:大时代背景下崇高理想无法实现的痛苦;'人生本是苦海"的生命本质的思考;寻找"小家"过程中不能如意的凄苦.
