重构我国行政诉讼类型之设想

行政诉讼类型化是20世纪以来各国行政诉讼制度发展的共同趋势之一。行政诉讼的类型化有助于公民诉权的切实维护和行政法治进程的推进,因而是一国行政诉讼制度变革的核心问题。我国的行政诉讼类型比较单一,难以回应司法实践的需求。为此,必须在借鉴域外经验和关照社会现实的基础之上,重新构建我国行政诉讼的基本类型。     

中国成都汉族群体三个Y-STR基因座复合扩增及其单倍型的研究

目的建立一种同步检测Y-STR基因座的方法。方法采用复合扩增的方法同时对三个基因座(DYS390、DYS391及DYS393)进行扩增。结果成功地对这三个Y-STR基因座进行了同步扩增,并用其对中国成都汉族群体进行群体遗传学研究。结论三个Y-STR基因座在中国成都汉族群体个人识别几率为0.8965±0.0081,证明这个体系可用于个人识别和群体遗传学研究。     

华东地区汉族人群D2S1399和D5S2500基因座的遗传多态性研究

目的研究D2S1399和D5S2500基因座在中国华东地区汉族群体遗传多态性。方法应用PCR、聚丙烯酰胺垂直电泳及银染技术检测D2S1399和D5S2500基因座的遗传多态性。结果D2S1399和D5S2500基因座在中国华东汉族群体分别检出11个和9个等位基因,其观察杂合度(Ho)分别为0.745和0.807,多态信息含量(PIC)分别为0.850和0.750,个体识别能力(DP)分别为0.958和0.917,非父排除率(PE)分别为0.554和0.643。结论D2S1399和D5S2500两个基因座是高度多态性STR基因座,在法医学中有重要应用价值。     

家兔急性胰腺炎死后不同时间眼玻璃体液淀粉酶变化

目的探讨急性胰腺炎死后不同时间眼玻璃体液淀粉酶变化。方法用1%牛胆酸钠诱导家兔急性胰腺炎动物模型建立,于死后不同时间和正常对照组,观察其淀粉酶变化。结果家兔急性胰腺炎死后72h眼玻璃体液淀粉酶含量(x)与死亡时间(y)存在相关关系,并导出其二项式回归方程为y=8.7420 0.7699x-0.0083x2(R2=92.62792,F=14.89734,P=0.001)。可作为推定早期损伤时间的参考指标。结论家兔急性胰腺炎死后不同时间眼玻璃体液淀粉酶改变为法医早期死亡时间推断提供了灵敏客观的实验依据。     

Component analysis of illicit heroin samples with GC/MS and its application in source identification

A novel method based on GC/MS and GC for component analyses of seized illicit heroin was established by using SKF525A as an internal standard. The main components in illicit heroin products such as heroin, O3-acetylmorphine, monoacetylcodeine, and O6-acetylmorphine were determined quantitatively and the organic adulterants such as paracetamol, acetaminophen caffeine and theophylline were detected qualitatively using the developed method. With these obtained data, 500 seized illicit heroin samples were divided into nine groups. The decomposition pattern of heroin was studied. The dependencies of both the decomposition pattern and the content ratios of monoacetylcodeine to heroin and monoacetylcodeine to O6-acetylmorphine on the source of the seized illicit heroin were observed. This information was used to develop a novel method for its source identification. The examination results were in agreement with the practical cases, thus providing significant information for detection of criminal cases involving illicit heroin.     

Characterization and haplotype analysis of 10 novel Y-STR loci in Chinese Han population

In this study, we analyzed allelic sequences of 10 novel Y-specific STR loci, DYS454, DYS510, DYS513, DYS520, DYS542, DYS544, DYS552, DYS561, DYS587 and DYS593, surveyed the distribution of haplotypes in a Chinese Han population. Extracted DNA was amplified with PCR, followed by a horizontal non-denaturing polyacrylamide gel electrophoresis with discontinuous buffer system. Purified alleles were sequenced on DNA sequencer (ABI Model 377) to verify the number of motif repeats. The number of alleles observed at each locus ranged from 3 to 8, yielding 102 haplotypes in 103 unrelated males samples. The allele diversity values for each locus ranged from 0.2099 (DYS544) to 0.7523 (DYS552). The haplotype diversity using all these loci was 0.9998. Our study revealed that they were valuable Y-specific markers for forensic applications.
