常见嗜尸性甲虫及蝇类虫体不同部位mtDNA的提取效果

目的探讨改良后十六烷基三甲基溴化铵(cetyltriethylammnonium bromide,CTAB)法对常见嗜尸性昆虫虫体不同部位mtDNA的提取效果。方法随机采集放置在呼和浩特地区室外草地家兔尸体上丽蝇科的丝光绿蝇[Lucilia sericata(Meigen)]、埋葬甲科的Nicrophorus fossor(Erichson)各13例,采用改良CTAB法分别提取每只昆虫头部、胸肌、腿部、翅膀4个部位的mtDNA,核酸蛋白测定仪检测DNA纯度及质量浓度,琼脂糖凝胶电泳检测其PCR产物,测定PCR产物序列,上传GenBank。结果 13例丝光绿蝇[Lu-cilia sericata(Meigen)]的胸肌均提取到了DNA,10例头部样本、6例腿部样本、4例翅膀样本得到DNA;13例Nicrophorus fossor(Erichson)胸肌DNA均提取成功,5例头部样本、8例腿部样本及3例翅膀样本提取出DNA。结论改良CTAB法可用于对嗜尸性昆虫胸肌及其他部位进行DNA的提取。     

论我国司法鉴定机构管理体制改革的途径与方法

对抗制的诉讼、证据制度对应于分散性、对立性的鉴定管理制度;职权性的诉讼、证据制度对应集中性、中立性的鉴定管理制度。因为诉讼对抗制的改革趋势必然要求鉴定管理制度的适度分散化。但就管理体制的现况而言．分散化管理模式根本不可行,因此应结合国情,建立有限度的鉴定机构集中管理方式。这种管理方式认为需以行政管理为主、行业管理为辅的中国特色模式。

SLOWLY BUT SURELY

海峡两岸刑事简易程序之比较

经历多次修法,两岸刑事简易程序出现不同格局。我国台湾地区刑事简易程序分简易判决处刑程序和简式审判程序,其适用范围、启动条件和审理方式大有区别。祖国大陆只有一种刑事简易程序,其适用范围与普通程序当然有别,而在审理方式、《判决书》之制作以及救济途径上,祖国大陆刑事简易程序与刑事普通程序并无分别。比较而言,台湾地区刑事简易程序相对合理,有值得借鉴之若干方面。祖国大陆应当建立多元格局之刑事简易程序,同时完善现行《刑诉法》规定之简易程序,改革刑事简易程序之救济途径。
