立法听证的立论基础探析

立法听证是我国民主立法的新形式。该制度源自于西方,现在几乎已经成为西方国家立法过程的必经程序。立法听证在较短的历史之内获得普世性的适用是因为其乃立立基于人类社会的一些基本价值要素,包括言论自由、身份平等、程序正义等等。对这些要素进行分析,有利于加深我们对立法听证制度的理解,规范其在实践中的运作形式,纠正一些偏出于其制度本义的现象。     

A comparison of endogenous and exogenous RNA reference marker as relevant for accurate Post-Mortem Interval estimation

The Post Mortem-Interval (PMI), also known as time since death, is of relevance for forensic routine casework and serves primarily as the basis for the determination of the time that has passed since the time of death. The existing, “classical” approaches are characterised by certain limitations because they are predominantly based on morphological examinations.The present study deals with the assessment of two molecular messengerRNA-markers in different kinds post-mortem human specimens concerning their ability to use them for the estimation of the time of death. Moreover, a comparison between carefully selected endogenous and one exogenous reference marker for the normalisation of the gene expression data as relevant for accurate PMI estimation is drawn.The evaluation showed that the used approach is methodologically useful but on consideration of the achieved results it was only possible to determine slightly meaningful tendencies. The tested exogenous reference marker was not suitable for sufficient data normalisation whereas the endogenous reference markers showed a stable expression. However, it was not possible to recognise a specific expression level of the genes within a PMI group when endogenous reference markers were used.     

补肾方含药血清处理的大鼠成骨细胞miRNA差异表达

目的 筛选补肾方含药血清干预的大鼠成骨细胞中差异表达的miRNA,为补肾方治疗骨质疏松症提供可供选择的目标miRNA,以探讨其通过调控靶基因表达发挥治疗效应的机制。方法 经细胞性状鉴定的原代大鼠成骨细胞用含药血清干预,采用miRNA芯片检测补肾方含药血清干预3 d与干预1 d的成骨细胞miRNA表达水平,并挑选差异表达2倍以上的miRNA进行定量PCR验证。结果 培养的原代细胞具有典型的成骨细胞性状特征。与对照血清相比,补肾方含药血清干预3 d的成骨细胞共有24个2倍以上表达差异的miRNA,其中上调的16个,下调的8个。差异表达2倍以上的miRNA定量PCR结果与芯片数据一致。结论 补肾方通过成骨细胞中差异表达的miRNA调控靶基因改善骨质疏松症。     

针刺对2型糖尿病大鼠脂肪组织INSR基因表达的影响

目的探讨针刺对2型糖尿病(type 2 diabetes mellitus,T2DM)机体脂肪组织胰岛素受体(insulinreceptor,INSR)基因表达的影响。方法给食源性肥胖大鼠腹腔注射小剂量链脲佐菌素复制T2DM模型,随机分为针刺组、优降糖组和模型组,设正常对照组。处理4周后,采用罗氏活力型血糖仪测空腹血糖(fast-ing blood sugar,FBS),采用放射免疫法检测空腹胰岛素(fastinginsulin,FINS),采用原位杂交检测脂肪细胞INSRmRNA表达,计算胰岛素敏感性指数(insulin sensitivity index,ISI)和稳态模型评估胰岛素抵抗(homeostasis model assessment of insulin resistance,Homa-IR)指数。结果与正常组比较,模型组FBS、FINS、ISI、Homa-IR水平显著上升(P<0.01),INSR基因水平表达显著降低(P<0.01);与模型组比较,治疗后优降糖组和针刺组FBS、FINS、ISI、Homa-IR显著下降(P<0.05,或P<0.01),INSR基因表达显著升高(P<0.01)。...
