多层螺旋CT检查在尸体颈椎损伤中的应用

对需要在尸体检验时进行颈椎多层螺旋CT(MSCT)检查的情形进行讨论,研究利用MSCT对疑有颈椎损伤的尸体进行颈椎检查的方法,并对一例疑似颈椎损伤尸体的颈椎提取后进行MSCT检查。发现对疑似有颈椎骨折尸体提取颈椎进行MSCT检查,可以快速精确地显示颈椎的细微骨折及骨折的空间分布,从而推断致伤方式。解决了传统尸检中费时费力,容易漏诊和误诊的问题。

益气活血化瘀法干预老年股骨干骨折患者术后高凝状态临床研究

目的 观察益气活血化瘀法对老年股骨干骨折患者术后高凝状态的影响。方法 将60例老年股骨干骨折患者随机分为中药组和西药组各30例,两组均采用闭合穿针髓内钉治疗,中药组术后给予益气活血化瘀法治疗,西药组给予利伐沙班治疗,比较两组干预前后D-二聚体、凝血酶原时间（prothrombin time,PT）,血小板计数（platelet count,PLC）以及患肢周径的变化。结果 两组患者术后凝血指标均较术前明显降低,差异均有统计学意义（P＜0.05）;两组手术前后凝血指标差值比较,差异无统计学意义（P>0.05）。两组术后均无下肢静脉血栓发生。中药组干预前后患肢周径的变化值大于西药组,差异有统计学意义（P<0.05）。结论 益气活血化瘀法与利伐沙班均能改善股骨干骨折患者术后的高凝状态,预防DVT的发生,但益气活血化瘀法治疗效果优于利伐沙班。

Application of the Iscan method to two- and three-dimensional imaging of the sternal end of the right fourth rib

Age determination is a major field of interest in physical and forensic anthropology. Among the different methods based on macroscopic skeletal study, the Iscan method, which analyzes the sternal end of the right fourth rib, is one of the most reliable. We applied the Iscan method to two- and three-dimensional multislice computed tomography (MSCT) reconstructions of the sternal end of the right fourth rib on 39 ribs. The intra-observer variability on MSCT reconstructions was good (gamma coefficient equal to 0.86; value of the Krippendorff's alpha reliability equal to 0.79); inter-observer variability on MSCT reconstructions was also good (gamma coefficient ranging from 0.82 to 0.88; value of the Krippendorff's alpha reliability ranging from 0.78 to 0.86). We demonstrated excellent agreement between the results of analysis of bone samples and those of the two- and three-dimensional images, in particular regarding bone projections, morphology of the pit and of its rim. The accuracy of age estimation did not significantly differ between the Iscan method applied to dry bones and the same method applied to MSCT images. Determination of the Krippendorff's alpha reliability coefficient for the inter-error method confirmed the agreement between phase estimations obtained with the two methods (ranging from 0.55 to 0.71). The real civil age was comprised in 21 cases out of 36 for assessment performed on dry bones and in 23 cases out of 36 on MSCT reconstructions, which represented 58.3% and 63.9%, respectively. Use of MSCT reconstructions in forensic anthropology offers many advantages: no bone preparation, no damage to bone material, and the possibility of application to living individuals.     

Comamonas testosteroni meningitis in a homeless man

We report a case of meningitis caused by Comamonas testosteroni in a 54-year-old, alcoholic, homeless man. He, as a pedestrian, was struck by a car and suffered multiple fractures of the facial bones including the left frontal sinus. Over the course of 2-week hospitalization, he was clinically diagnosed with multiple cerebral and cerebellar infarcts resulting in altered mental status. He was pronounced dead 15 days after the injury. At the time of autopsy, diffuse purulent meningitis was found on gross examination. A swab culture of the brain surface was positive for C. Testosteroni, a saprophytic organism commonly found in soil and water. This is the first reported case of fatal meningitis caused by this micro-organism.     

Blunt force cranial trauma in the Cambodian killing fields

In this paper we present a unique pattern of blunt force cranial trauma that was observed in 10 of a sample of 85 crania from a Cambodian skeletal collection comprised of Khmer Rouge victims. Initial examination of the trauma, which presents as substantial damage to the occipital with fractures extending to the cranial base, suggested the pattern was classifiable as a basilar or ring fracture. However, further investigation, including trauma analysis and historical research, revealed that this fracture type is distinctive from basilar and ring fractures. Historical data indicate that a particular execution method was the likely source of the trauma. Recognition of this trauma pattern is significant because it exemplifies the distinct fracture configuration resulting from an apparently categorical and methodical execution technique. Identification of this fracture type could potentially assist forensic investigators in the recognition of specific methods of murder or execution.     

The Self-salvation of Capitalist Society——Giddens' Criticism of Historical Materialism and the Third Way

Giddens fully absorbs the Marx's capitalism critical theory of capital criticism as the core by including Marx in historical framework of late modernity. Based on fracture of modernity, Giddens criticizes historical materialism and develops structural theory of understanding of the developed capitalist society. Thereby, Giddens shows the current status of modernity: pluralistic structure and high risk of society dominated by the forces of globalization. According to the principle, Giddens proposes “the third way” as self-salvation of capitalist society: adhere to the ideals of socialism, beyond the traditional opposition of government and market, making full use of the balance between state and market to build a society of positive welfare. Laying aside political label of “the third way”, the exploration of the balance between government and market is of great practical significance for China to promote the balance between government and market, and to manage the challenge of globalization. However, the position of Postmodernism indicates that Giddens criticism of Marx's historical materialism is a failure undoubtedly.     

Perimortem or Postmortem Bone Fractures? An Experimental Study of Fracture Patterns in Deer Femora*

The determination of perimortem trauma is important for forensic anthropologists. Characteristics of bone fractures such as sharp edges, presence of fracture lines, the shape of the broken ends, fracture surface morphology, fracture angle on the Z-axis, and butterfly fractures are said to differentiate perimortem from postmortem trauma. A Drop Weight Impact Test Machine was used to break 76 deer femora of various ages since death. The results of this study suggest that the characteristics listed above are unreliable at differentiating a perimortem fracture from a postmortem fracture in a forensic case. There are, however, statistically significant differences between fresh bones broken less than 4 days old and dry bones broken 44 days or 1 year old after death.
