几种视觉诱发电位技术推断正常成人远视力的比较

目的比较研究几种图形视觉诱发电位技术对视力推断的价值。方法取正常眼40只,分别测试其图形翻转视觉诱发电位、黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位,据此推算实验视力,分别与真实视力进行比较,同时各种方法进行彼此比较。结果黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位较之图形翻转视觉诱发电位能更为准确、方便、快捷地反映真实视力水平。结论黑白条栅扫描视觉诱发电位和红黑条栅扫描视觉诱发电位与图形翻转视觉诱发电位一样,可用于眼外伤的法医学鉴定。     

司法行为模式论——以行为理论为视角

行为模式的差异性决定行为据以发生的权力在属性上的差别,而行为模式的差异性则往往由行为对象所决定。正是司法行为对象的差异性决定了司法行为体系中存在着目的行为、戏剧行为、规范调节行为以及交往行为等不同模式及其相互之间的差异性,而这种行为模式的差异性又决定了作为司法权构成要件的司法解释权、司法审判权、司法监督权与司法调解权等四项子权力在行为模式上的差异性。

丰富环境对脑梗死大鼠梗死灶周围血管内皮生长因子受体的影响

目的:研究丰富环境对大鼠局灶性脑梗死后梗死灶周围血管内皮生长因子受体的影响.方法:采用开颅电凝法制作SD大鼠右侧大脑中动脉缺血(MCAO)模型,术后第24小时随机分为丰富环境(EE)组和标准环境(SE)组.以免疫组织化学法检测血管内皮生长因子受体Flt-1及Flk-1的表达.结果:大鼠大脑中动脉闭塞后,缺血区神经元变性、坏死,Flt-1和Flk-1在缺血周边区表达明显增加,经丰富环境干预后,血管内皮生长因子受体表达大量增加.结论:丰富环境可促使血管内皮生长因子受体表达上调,进而促进微血管新生,有利于脑损伤修复.     

Exsanguinated blood volume estimation using fractal analysis of digital images

The estimation of bloodstain volume using fractal analysis of digital images of passive blood stains is presented. Binary digital photos of bloodstains of known volumes (ranging from 1 to 7 mL), dispersed in a defined area, were subjected to image analysis using FracLac V. 2.0 for ImageJ. The box-counting method was used to generate a fractal dimension for each trial. A positive correlation between the generated fractal number and the volume of blood was found (R(2) = 0.99). Regression equations were produced to estimate the volume of blood in blind trials. An error rate ranging from 78% for 1 mL to 7% for 6 mL demonstrated that as the volume increases so does the accuracy of the volume estimation. This method used in the preliminary study proved that bloodstain patterns may be deconstructed into mathematical parameters, thus removing the subjective element inherent in other methods of volume estimation.     

Palatal rugae pattern in a Portuguese population: a preliminary analysis

Palatal rugae have been related with specific racial groups and are said to be useful in sex discrimination. This work aimed to characterize the palatal rugae patterns in a Portuguese population. Fifty plaster casts were examined for first and third rugae shape evaluation; shape, frequency, and association with sex were studied. In females, the most prevalent first rugae were the straight type on the right and the curve type on the left; in males, the straight type was the most prevalent on both sides. The most frequent third rugae type was sinuous on both sides, in both sexes. No significant sexual dimorphism in rugae shape was found (p > 0.05). When comparing these results with those from other investigations, it was clear that a particular rugae pattern could be established for different ethnic groups. However, the small sample size justifies further work in larger samples to validate these findings.     

Decaying Mouse Volatiles Perceived by Calliphora vicina Rob.‐Desv.

Volatiles emitted by decaying human remains are in the focus of recent research. The identification of core volatiles in this field is of high importance, because cadaveric volatiles generally show high variation. In this study, the volatile profiles of five mice (Myodes glareolus) were sampled with charcoal filter tubes from their time of death until advanced decay. Eleven compounds were quantitated by means of gas chromatography–mass spectrometry. Electroantennographic experiments with female Calliphora vicina antennae led to the identification of dimethyl trisulfide, dimethyl disulfide, nonanal, hexan‐1‐ol, 1‐octen‐3‐ol, 3‐methylbutan‐1‐ol, and heptanal as electrophysiologically active compounds. When these were compared, dimethyl trisulfide (17 ng/μL) and dimethyl disulfide (11 ng/μL) were found to be emitted in higher concentrations. The roles of these compounds and nonanal as core volatiles for cadaver detection or postmortem time determination and their correlation to the stages of decay and the accumulated degree days are discussed.

Social Construction： the Reconstruction of China＇s Interests Pattern in Two--way of Movement

在社会转型初期,自由市场逻辑主导下的社会变革激发了社会活力,释放出了巨大能量,但也因利益在社会成员中的不均衡分布而产生对经济发展公平性的质疑。伴随市场力量的不断强大,社会自我保护力不断增强,使得社会矛盾呈愈演愈烈之势。在世界社会治理机制由一元向多元转变的趋势下,中国也开启了社会治理机制的变革之路,其核心议题在于建构何种国家、市场与社会力量的分配格局。这对于深化中国社会转型进程,实现社会稳定有序,奠定社会管理的社会基础具有十分重要的意义。然而,如何进行社会建设,不能给出简单的、想当然的结论,而需要挖掘其背后的支配逻辑——双向运动,以此重塑国家、市场与社会三者之间的关系。
