构建有效的权力监督制约机制

权力监督与制约是完善现代宪政与建设社会主义民主政治的一项重要举措。根据理论联系实际的原则,注重理论性与实践性的统一,抓好权力监督与制约的机制建设,对于权力的有效监督与制约以及当代和谐社会政治文明的建设均有重要的借鉴意义。     

计算机犯罪现场中的取证技术及应用

科学有效地应用计算机取证技术是侦办计算机犯罪案件的关键。计算机取证也称为计算机法医学,是把计算机运行环境看作是犯罪现场,运用相关的辨析技术,对计算机犯罪行为进行法医式的解剖,从而搜寻确认罪犯及犯罪证据,并据此提起诉讼。从理论上讲,计算机取证人员能否找到犯罪证据取决于有关犯罪证据是否被覆盖。但从海量的数据里面寻找蛛丝马迹是一件非常费时费力的工作,侦查人员必须具备相应的专业技能,并按照科学合理的步骤来实施计算机犯罪现场中的取证工作。     

实验性轻度病毒性心肌炎的组织病理学观察

为探索轻度病毒性心肌炎的法医病理学诊断方法,以适量 Coxsackie B3病毒感染 Balb/c小鼠造成小鼠轻度病毒性心肌炎,对病鼠的心、肝、脾、肺、肾进行常规病理学检查。结果发现,心肌炎小鼠的各器官出现不同程度的病理改变。实验提示,病毒性心肌炎是一类多器官病变的疾病;对多器官进行病理学观察和综合分析是轻度病毒性心肌炎的组织病理学诊断的有效方法之一。     

Blood carbofuran concentrations in suicidal ingestion cases

We describe four fatal cases due to ingestion of carbofuran, a carbamate insecticide. Carbofuran was detected in the gastric contents using thin layer chromatography (TLC) and gas chromatography/mass spectrophotometry (GC/MS), and quantified in the blood using a gas chromatograph equipped with nitrogen-phosphorus detector (NPD). Fatal concentrations of carbofuran in blood ranged from 0.32 to 11.6 microg/ml.     

Allelic structure and distribution of two STR loci, D8S580 and D22S442, in the Japanese population

The allelic frequency and structural characteristics of two STR loci D8S580 and D22S442 were investigated using blood samples from 143 unrelated healthy Japanese individuals. Thirty-eight alleles in D8S580 locus and 13 alleles in D22S442 locus were identified. The discrimination power, heterozygosity, and the polymorphic information content of those loci displayed high values (0.98, 0.88, and 0.87 in D8S580 and 0.97, 0.86 and 0.85 in D22S442), and their frequency distributions met Hardy-Weinberg equilibrium expectations. The allelic pattern of D8S580 was complex and differentiated into three groups (group I: alleles 184-194bp; group II: alleles 203-223, 235, 239, 243, 252 and 255bp; group III: alleles 227-286bp). Most of their alleles contained five categories of repeat units (A: aaaag; B: aaag; C: aagg; D: caag; E: agaa). On the other hand, D22S442 contained only two types of repeat units (A: agga; B: aggg). The present study, hence, proves that both D8S580 and D22S442 are highly polymorphic and represent stable genetic markers applicable to forensic investigations.     

Population data of 13 STRS in southern Spain (Andalusia)

Allele frequencies for the 13 STRs included in the AmpFl/STR Profiler Plus and Cofiler kits were determined for an Andalusian population (southern Spain).     

Sequence polymorphism of mitochondrial D-loop DNA in the Taiwanese Han population

In order to demonstrate the sequence diversity of mitochondrial D-loop DNA in the Taiwanese Han population, we established a database of 155 unrelated individuals. For each individual, the complete 980bp DNA region from the 5' end of HVI to 3' end of HVII segment was sequenced. In these 155 sequence data, 149 different haplotypes were observed, amongst these haplotypes, 144 were unique, 4 were found in 2 individuals and 1 was found in 3 individuals. When compare to the Anderson sequence, 144 transitions, 24 transversions, 5 insertions and 5 deletions were found. Eight positions exhibited more than one polymorphic sequence, six exhibited two variants while two exhibited three variants. Over the 1024bp that was analysed, pairwise differences between the sequences were 11.35+/-3.53bp. The sequence and nucleotide diversity were 0.9994 and 0.0116, respectively. The probability of two individuals randomly matching over the entire control region was 0.007. The diversity in the mitochondrial D-loop indicates the value of this locus for casework within Taiwan.     

Histopathological findings of cardiac conduction system of 150 Finns

One hundred and fifty heart specimens were collected from the cases submitted for autopsy in the Department of Forensic Medicine in the University of Turku in March-May 1995 and May-July 1996, respectively. The cardiac conduction system (CCS) of these hearts were examined in order to find out the histopathological changes in the CCS of Finnish persons and their forensic pathological significance. There were 94 males and 56 females. Almost all age groups were included. The results revealed that in most of the persons the fibrous tissue and fatty tissue in the CCS increased with aging. In about half of the persons, there was deposition of calcium in the central fibrous body, pars membranacea, and the top of the musculature in the interventricular septum. In seven cases, the atrioventricular node (AVN), His bundle (HB) or bundle branches (RBB, LBB) were compressed by the calcium deposition. Hemorrhage, inflammation, amyloidosis, tumor, fatty infiltration and developmental malformations were observed in 31 cases. Twenty-eight cases died of myocardial infarct, among them, no involvement of the CCS could be observed. The authors concluded that routine examination of the CCS is helpful for revealing diseases of the CCS and improving the quality of forensic pathological diagnosis.     

Unusual homicide by air gun with pellet embolisation.

A homicidal case by an air gun involving a 73-year-old woman who was found dead in her home is described. At autopsy, two gunshot wounds were observed on the left anterior chest and the right back. There was neither exit wound nor powder burns. The fatal pellet, 0.9 g and 5.5mm diameter, penetrated the left anterior chest and the heart to cause cardiac tamponade (200 ml) before lodging in the left subclavian artery. Death was due to cardiac tamponade.This case has exhibited two rare phenomena: homicide by an air gun and pellet embolisation. This is the first homicide case by use of air gun in Japan and demonstrates that although it may be rare, air guns can be used as potential homicidal weapons. This experience will alert our society and others on the potential hazards of air guns we have tended to regard as toys.     

Interests,Power and China's Difficult Game in the Shanghai Cooperation Organization (SCO)

The Shanghai Cooperation Organization (SCO)—an organization interpreted in various ways—officially announced that it intended to ensure regional security by countering international terrorism, ethnic separatism and religious extremism. This article discerns the motivations of the SCO members, arguing that they have their respective, albeit occasionally mutual, interests and priorities. There is generally asymmetry of interests—the principal reason why the SCO's strategic situation is largely a suasion game between China and the members—with China demonstrating a greater interest in the SCO; moreover, the power asymmetry between China and the Central Asian members and the power equality between China and Russia further complicates the situation. This sophisticated relationship implies that despite some measurable results, the SCO faces tremendous challenges in becoming a well-established regional organization.
