对公安院校警体教学改革的研究与探讨

在加快改革开放和发展社会主义市场经济的新形势下,公安工作面临的形势更加严峻,任务更加艰巨、繁重。因此,对警察的身体素质和警务实战技能提出了越来越高的要求。公安院校作为培养未来警察的重要基地,警体教学应贴近公安工作实际。强化课程和教材建设,优化教学整体结构,精选教学内容。进一步建立和完善以增强学生体质,提高体能为基础、掌握警体技能为重点、强化实战运用能力为目标的教学训练体系。使警体教学为增强公安队伍战斗力发挥更大的作用。本文就有关警体课程和教学训练中存在的一些问题进行探讨,目的是为警体教学的改革提供参考。     

Selenium determination in mother and child's hair by electrothermal atomic absorption spectrometry

A method for the selenium determination in a mother and her child's hair using palladium as a chemical modifier was optimized. The sample was digested with nitric acid and hydrogen peroxide and diluted to 5 ml. To achieve complete mineralization the samples were ashed at 1200 degrees C in the presence of palladium as a chemical modifier. The optimum atomization temperature was 1900 degrees C. The precision and accuracy of the method were studied using the reference material CRM 397. Results of calibration using aqueous standards and the standard addition method were compared. The method was applied to the selenium determination in 30 samples of the mother's and child's hair. The levels found were 0.54 +/- 0.34 microgram/g for mother's hair and 0.77 +/- 0.25 microgram/g for child's hair.     

Pseudolaminar necrosis in cyanide intoxication: a neuropathology case report

We describe the gross and microscopic neuropathological changes in the brain of a 17-year-old male who died 4 days after being poisoned with cyanide. Previous reports indicate that following cyanide intoxication, the brain develops diffuse hypoxic/ischemic changes, predominantly of the basal ganglia. The case we describe here had similar features but in addition showed striking laminar necrosis of the cerebral cortex. This finding in cyanide poisoning has been previously demonstrated by neuroimaging, but not pathologically.     

Y-chromosome STR haplotypes in Somalis

A total of 201 males from Somalia were typed for the Y-chromosome STRs DYS19, DYS385a/b, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 with the PowerPlex Y kit (Promega). A total of 96 different haplotypes were observed and the haplotype diversity was 0.9715. The number of unique haplotypes was 71 while the most common haplotype was observed 24 times.     

Mitochondrial DNA error prophylaxis: assessing the causes of errors in the GEP'02-03 proficiency testing trial

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu.     

Y-chromosome STR haplotypes in Danes

A total of 185 unrelated Danish males were typed for the Y-chromosome STRs DYS19, DYS385a/b, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 using the kits PowerPlex Y (Promega), ReliaGene Y-Plex 6 and ReliaGene Y-Plex 5 (Reliagene Technologies). A total of 163 different haplotypes were observed and among these, 144 haplotypes were unique. The gene diversity was 0.9985. In DYS392, a variant allele migrating as a 10.2 allele was observed. Sequencing of the allele showed a deletion upstream the repeated area.     

探索“两课”教学与学管工作一体化的新模式

加强学生思想政治教育势在必行。我校思想政治教育存在"两课"教学与学生思想实际脱节,学管工作方法滞后,与学生沟通少等问题。构建思想政治教育模式的具体做法包括:实行思想政治教育辅导员制,采取观察法、调查法、反馈法、实践法等。     

Nine autosomal STRs genotype profiles in a sample from Córdoba (Argentina)

Nine STRs loci have been typed in a sample from Córdoba (Argentina).     

Y-chromosome STR haplotypes in Córdoba (Argentina)

Eight Y-chromosome STRs were investigated in a male population sample from Córdoba region (Argentina). Complete Y-chromosomal STRs haplotypes were obtained in 100 individuals, among which 91 different haplotypes were observed. The most common haplotype was shared by 4% of the sample, while 86 haplotypes were unique. The gene diversity was 0.9875 and the discrimination capacity was 0.8600. The combined polymorphism provides a powerful discrimination tool for routine forensic applications.
