《道路交通事故受伤人员伤残评定》中精神伤残程度司法鉴定相关问题探讨

在法医精神病学鉴定实践中,精神伤残的评定越来越多。现行《道路交通事故受伤人员伤残评定》标准中关于精神伤残评定的相关条款过于笼统,可操作性差,常因认识不一致而产生歧义。本文结合典型案例主要从三个方面对精神伤残司法鉴定中常见问题进行探讨:(1)在评定智力缺损程度时,应结合伤前智商进行评定;(2)精神伤残评定的时间应在医疗终结后一年;(3)精神伤残评定中应引入量表进行客观评价。     

挤压家兔后肢导致急性肝损伤和抗氧化能力降低

目的本实验观察挤压家兔后肢导致肝氧化损伤,探讨氧化应激在挤压家兔后肢导致肝损伤中的作用。方法用标准重物间断压迫家兔后肢复制模型。采用生化方法检测ALT和AST活性;分析天平称重方法检测肝脏湿干重比值(W/D);比色法测定肝组织超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GSH-Px)活性和总抗氧化能力(T-AOC)以及丙二醛(MDA)含量变化;并观察肝组织病理学改变。结果血清ALT和AST活性明显增高(P<0.01),肝细胞明显肿胀,肝窦轻度淤血,而肝脏湿干重比值(W/D)轻度增加(P<0.05);肝脏氧化损伤明显加重,MDA含量增高,而肝脏抗氧化能力下降,SOD、CAT、GSH-Px活性和T-AOC分别比对照组降低了17%、29%、24%和21%(P均<0.01)。结论挤压家兔后肢引起急性肝损伤及肝脏的抗氧化能力下降;肝脏局部抗氧化能力下降可能是肝损伤的重要因素。     

两种DNA提取法对不同色泽肋软骨STR分型成功率的比较

目的比较两种DNA提取法对不同色泽肋软骨的DNASTR分型结果的影响。方法利用Chelex-100法和酚-氯仿法,分别对30例不同色泽的腐败尸体肋软骨进行DNA提取,STR复合扩增,ABI3100型基因分析仪对扩增产物进行检测。结果用酚-氯仿法提取的30例腐败尸体肋软骨,均检测到全部STR基因座的等位基因型。用Chelex-100法提取的肋软骨中,22例(11例白色、8例淡黄色、3例黄色)检测出全部STR基因座的等位基因型;7例(3例黄色、4例黄褐色)检测出部分STR基因座的等位基因型;1例黑灰色的腐败尸体肋软骨,未检测出STR基因座的等位基因型。结论根据肋软骨的色泽,选择适宜的DNA提取方法。对于颜色较深的肋软骨,用酚-氯仿法进行DNA提取有助于提高其STR基因座的检出率。

执政党执政合法性的内涵与资源探析

在政党政治时代,执政合法性是任何执政党必然面对和必须重视的首要问题,也是执政党有效运作的首要条件,缺乏合法性即面临合法性危机,就会导致执政党执政权力的削弱甚至执政地位的丧失。     

Morphometrics of the hyoid bone for human sex determination from digital photographs

The identification of unknown remains is very important. When unknown remains are found, anthropologists first determine their sex and age. The sex of most skeletons is determined by their shape. In the hyoid bone, the shape is sex related, so it can be used forensically to determine the sex. This study focused on sex-based morphometry of the hyoid bone in Koreans using digital photographs. Hyoid bones from 52 males and 33 females were examined. For each subject, we took 34 measurements from photographs using a computer program, and the data were analyzed statistically using SPSS 11.0. Twenty-one of 34 measurements had significant sex differences (p<0.05). The discriminant functions based on three measurements (X(1)-X(3)) were as follows: The accuracy of discriminant functions is 88.2% in both groups, so these can be used to distinguish males from females in a statistically significant manner.     

Characterization of the N+3 stutter product in the trinucleotide repeat locus DYS392

Stutter products generated during DNA amplification by the polymerase chain reaction (PCR) may complicate mixture interpretation. The PCR amplification of the DYS392 locus typically results in three distinct detectable PCR products: the true allele product (N), a stutter product three bases smaller (N-3), and a reproducible low-level product, three bases larger (N+3). Sequence analysis of the N+3 product demonstrated that its sequence is one TAT repeat longer than the true allele product. Our experiments demonstrated that the quantity of both N-3 and N+3 stutter increased as the allele number increased. The percent stutter also increased as the magnesium concentration was increased in the reaction, as well as when the amount of input DNA was decreased. As both stutter products behave in a similar and reproducible fashion, the same rules that apply to the interpretation of N-3 stutter products in short tandem repeat analysis, can be applied to N+3 stutters. The characterization of the DYS392 N+3 product is the first detailed published study of a stutter product larger than the true allele.     

Forensic genetic analysis of mitochondrial DNA hypervariable region I/II sequences: an expanded Korean population database

We have analyzed variation of the mitochondrial DNA (mtDNA) hypervariable segments I and II (HVS-I and HVS-II) in 185 randomly chosen individuals from Korea to provide an expanded and reliable Korean database. Combined sequence comparison of HVS-I and HVS-II led to the identification of 167 different haplotypes characterized by 154 variable sites. One hundred and fifty-one of the haplotypes were individual-specific, 14 were found in two individuals and 2 were found in three individuals. A pairwise comparison of the 185 HVS-I/II sequences found an average of 10.11 +/- 4.63 differences between individuals. The random match probability and gene diversity for the combined hypervariable regions were estimated at 0.66% and 0.9988, respectively. Analyzing the expanded database including three previously reported data sets and the present data using haplogroup-based comparisons and comparison with closely related sequences allowed errors to be detected and eliminated, thus considerably improving data quality. Sample division comparisons based on PhiST genetic distance measures revealed no significant population differentiation in the distribution of mtDNA sequence variations between the present data set and a database in The Scientific Working Group on DNA Analysis Methods (SWGDAM), but did indicate differences from other sets of data. Based on the results of mtDNA profiles, almost all of the mtDNA types studied here could be classified into subsets of haplogroups common in east Asia, and show that the Koreans possess lineages from both the southern and the northern haplogroup complexes of east Asian populations. The new data, combined with other mtDNA sequences, demonstrate how useful comparison with closely related mtDNA sequences can be for improving database quality, as well as providing haplotype information for forensic and population genetic analyses in the Korean population.
