里耶秦简中出现了很多植物的名称,绝大多数是与当地百姓生活息息相关的农作物。按照人们的利用情况,可将它们分为粮食作物、瓜果蔬菜、竹木类经济作物、麻及其他草本植物。对它们科属的考证,食用、使用情况的梳理、探讨,可以使我们对当时当地的农作物种类有一个宏观的认识。这也对研究古代湘西地区的农史、物质文化史、区域环境史有重要意义。

脐带血含有丰富的造血干细胞,已经成为替代骨髓移植治疗多种疾病的良好资源,但尚存多种不足与难题。国内外大量研究证实,脐带血干细胞具有肯定的支持造血功能,在体外培养条件下可以扩增,并且在一定的诱导作用下可分化为骨、软骨、肝、内皮等多种组织细胞。脐带血干细胞具有低免疫原性等很多优点,已成为干细胞研究领域的热点。目前分离培养脐带血干细胞的方法多样,日趋成熟,临床应用脐带血干细胞移植治疗的疾病已达80余种,但仍存在许多弊端,尚需进一步的研究。

北大汉简《周驯》和《吕氏春秋》《说苑》《左传》《公羊传》《史记》都记载了"桑下饿人"报恩的故事。这一故事在产生初期就存在两个版本,根据异同可将其分为甲、乙两类。在故事叙述上,甲类文献以桑下饿人受恩、报恩为主线,乙类文献则以赵盾宫中遇险被救为主线,并出现了新人物、新情节——提弥明杀獒救盾。在故事流传中,汉代画像石等图像资料及敦煌遗书《古类书语对》、元杂剧《赵氏孤儿大报仇》等表明流传的诸版本杂糅了甲、乙文献的多种元素,但以《左传》为代表的乙类文献明显影响更大。

背景:被动吸烟致对胚胎神经系统发育影响的报道比较少见,并缺乏有效的防治措施。我们以往实验证明,被动吸烟可致仔鼠海马组织神经生长因子含量减少,学习能力下降。小脑皮质也是胚胎期神经生长因子水平较高的部位之一,被动吸烟也可能降低小脑皮质神经生长因子的含量。牛磺酸在哺乳类动物的脑内含量丰富,神经元和神经胶质细胞可能通过选择性储存和释放牛磺酸,以维持脑组织的正常活动,牛磺酸的合成和摄入受阻可能导致其功能异常。因此推测胚体内一定水平的牛磺酸与神经生长因子含量具有相关性,而小脑皮质神经生长因子含量的减少可能是仔鼠脑损伤的原因之一,故设计此实验。目的:探索被动吸烟对仔鼠所致脑损害机制及牛磺酸的干预作用。设计:随机对照动物实验。单位:山西医科大学汾阳学院。材料:实验于2001-03/2001-12在山西医科大学汾阳学院中心实验室进行。选Wistar雌性大鼠21只,体质量150～210g,采用编号随机分组方法分为3组,每组7只:被动吸烟组,被动吸烟+牛磺酸组,正常对照组。3组大鼠均于受孕的第2天起进行处理至自然分娩。被动吸烟组给予连续实验性吸烟,每日吸烟前用生理盐水0.65mL/只灌胃;被动吸烟+牛磺酸组于每日吸烟前用牛磺酸500mg/kg灌胃;正常对照组不予吸烟,每日用生理盐水0.65mL/只灌胃。方法:各组孕鼠分娩的仔鼠称量体质量后断头法处死,分离出脑并称重,在沸生理盐水中煮5min。再分离出小脑,用免疫放射测定法测神经生长因子含量。以小脑皮质神经生长因子蛋白变化为指标观察被动吸烟及牛磺酸对其的影响。主要观察指标:各组仔鼠体质量、脑质量和小脑神经生长因子蛋白的比较。结果:21只孕鼠的147只仔鼠检测数据进入结果分析。被动吸烟组仔鼠的体质量、脑质量和小脑神经生长因子蛋白水平分别与正常对照组和被动吸烟+牛磺酸组比较均显著降低(P0.05)。结论:被动吸烟可能是导致仔鼠小脑皮质神经生长因子水平下降的因素;牛磺酸可能对被动吸烟所致仔鼠脑损害具有保护作用。
