国人载脂蛋白E基因多态性与冠心病发病之间的相关性

目的 探讨载脂蛋白E基因112bp与158bp位点多态性与血脂水平及冠心病发生之间的关系。方法采用生物化学法分别测量经冠状动脉造影证实的89例冠心病患者及43例正常人空腹血脂水平，应用聚合酶链反应限制片长多态性分析方法对载脂蛋白E基因DNA244bp的5’末端片段进行限制性片段长度多态性分析。结果冠心病组甘油三酯、总胆固醇、低密度脂蛋白、载脂蛋白B及脂蛋白（a）水平均高于对照组（P〈0．05），而载脂蛋白A1水平则低于对照组（P〈0、05）；冠心病组载脂蛋白Eε2基因型频率明显为低（P〈0．001）。结论载脂蛋白E基因多态性特征会明显影响人群中个体的血浆脂质水平，从而增加人群中个体发生冠心病的危险。     

老年大鼠麻醉后学习记忆能力与海马乙酰胆碱含量的关系

伏期,并绘制学习曲线.比较两组大鼠海马胆碱类神经递质的含量并绘制趋势图,比较变化趋势的异同.结果 认知损害不明显组大鼠海马中乙酰胆碱浓度在水迷宫训练的头2 d明显上升,后3 d找到平台后浓度则不再上升,认知损害明显组这一趋势则不明显,始终处于偏低水平.海马中胆碱浓度变化曲线两组相似,但认知损害明显组在训练后3 d的胆碱浓度明显高于认知损害不明显组.结论 异氟醚麻醉2 d后35.3% 老年雄性SD大鼠的空问学习记忆能力下降,这种损害与海马内胆碱类神经递质浓度及其变化存在明显的内在关联.     

半乳糖凝集素-3及骨桥蛋白在食管癌中的表达及其意义

目的 研究半乳糖凝集素-3(Gal-3)、骨桥蛋白(OPN)在食管癌中的表达情况及其临床意义.方法 选取2006年至2008年接受手术治疗的食管癌患者37例,男28例,女9例,年龄41～82岁.应用荧光PCR及ELISA方法分别检测食管癌组织、癌旁组织及正常食管组织Gal-3 mRNA、OPN mRNA和血浆中Gal-3、OPN的水平,并结合术后随访,对其表达差异进行分析.结果 37例食管癌患者的肿瘤组织与癌旁组织及正常食管组织中Gal-3 mRNA相对表达值差异有统计学意义(F=11.934,P<0.05).三者之间OPN mRNA相对表达值差异有统计学意义(F=4.269,P<0.05).不同分期患者的食管癌组织Gal-3mRNA和OPN mRNA表达差异有统计学意义(F=3.216,P<0.05),而与患者的年龄、性别和肿瘤病理性质无关.复发组血浆中Gal-3和OPN水平及癌组织中的Gal-3 mRNA和OPN mRNA表达均高于未复发组(P相似文献
