Evaluation of eosin-fluorescence in the diagnosis of sudden cardiac death

The diagnostic significance of the eosin-fluorescence method was evaluated and compared with the enzymehistochemical β-hydroxybutyrate-dehydrogenase method (β-HBDH) and the degree of hyperchromasia in 568 samples from 24 β-HBDH-negative and β-HBDH-positive sudden cardiac deaths (SCD) and 23 non-cardiac deaths as controls. The effect of autolysis was investigated separately on isolated human hearts at +4°C and +22°C. All samples were examined without any knowledge of clinical or autopsy data. Normal olive-green fluorescence was observed in only five individuals of the control group and two in the β-HBDH-negative one. The frequency of the yellow-fluorescence and hyperchromasia increased from the control subjects towards the β-HBDH-positive-ones. The difference in frequency distribution of fluorescence between the groups was statistically highly significant (P < 0.001). The change in fluorescence did not correlate with the loss of β-HBDH-reaction or the distribution pattern of hyperchromasia. Postmortem autolysis did not change the fluorescence significantly but the 78% wrong positive subjects in the control group render this method too sensitive and unreliable for medicolegal purposes.     

钝力性心脏外伤38例尸检病理学研究

本文研究表明钝力作为原始致伤因素作用于胸部通过压、拉、剪切、旋转等可引起钝力性心脏外伤包括心脏震荡、心脏挫裂伤、心脏玻裂、心脏断离等原发性心脏外伤和继发性乃至迟发性心脏外伤，诸如外伤性心脏炎、冠脉血管炎、血栓形成、外伤性心肌梗塞、外伤性冠状动脉瘤、外伤性室壁瘤、迟发性外伤性心脏破裂等。致命性的心脏震荡，除急性冠循环障碍和心失常外，还可有心脏传导系统和神经组织损伤，尤其心肌肌膜爆裂（ｓａｒｃｏｌｅｍｍａｂｕｒｓｔ）及相应的原纤维膨出畸形变可以作为心脏震荡性外伤的形态学指证。外伤性心肌梗塞和迟发性外伤性心脏破裂以突然发生在外伤后的一定间隔期为特征，应予特殊注意．     

血浆中组织蛋白酶L在大鼠急性心肌缺血及缺血再灌注后的表达

目的 检验大鼠心肌缺血及缺血再灌注后组织蛋白酶L在血浆中的表达,探讨其能否作为心肌缺血标记物.方法 建立大鼠急性心肌缺血模型（心肌缺血30 min、1h、2h组）、缺血再灌注模型（缺血再灌注组）以及异氟烷预处理后的缺血再灌注模型（异氟烷预处理组）.同时设有正常对照组、假手术组以作对照.用ELISA法检验血浆中组织蛋白酶L的含量,同时用TTC染色测量心肌梗死面积. 结果 大鼠急性心肌缺血后,各组血浆中的组织蛋白酶L含量与正常对照组、假手术组相比,差异无统计学意义（P＞0.05）.缺血再灌注组,血浆中组织蛋白酶L的表达增多到正常对照组2.37倍（P＜0.05）.异氟烷预处理组血浆组织蛋白酶L和心肌梗死面积都较缺血再灌注组降低（P＜0.05）.结论 血浆中组织蛋白酶L不适合作为单纯急性心肌缺血的早期血浆标记物,异氟烷预处理可以降低缺血再灌注造成的血浆组织蛋白酶L高表达.     

我国民事诉讼标的及其识别问题分析

民事诉讼标的是指法院予以审理和裁判的对象。我国的民事诉讼标的理论吸收大陆法系诉讼标的理论基础,形成民事纠纷说、新二分支说、分别识别说与为实践部门普遍接纳的旧实体法说等诸学说。其争议焦点主要围绕给付之诉的诉讼标的识别标准进行。从利于诉讼实践的角度出发,仍应坚持实体法学说,但诉讼标的的识别要以原告向法院提出的实体法律关系或请求权为准,未向或未能向法院提出的实体法律关系或请求权不能作为识别依据。     

浅谈石油企业职工旧观念的表现及对策

要维护职工队伍的稳定,推动企业制度改革的深入进行,关键在于干部职工转变旧的思想观念,打破固有的思维模式。要突出职工的形势任务教育;加大职工综合素质的培养力度;强化职工的民主管理;落实绩效考核。

外伤性脑梗死25例法医临床学分析

目的探讨外伤性脑梗死法医临床学鉴定的要点。方法对25例外伤性脑梗死的案例进行回顾性分析,包括一般情况、梗死部位、临床表现等。结果 25例被鉴定人中以儿童和老年人多见,并均有明确的颅脑外伤。脑梗死部位好发于大脑基底节-内囊区或额、颞、顶叶皮层区。结论外伤性脑梗死的损害后果与脑梗死发生部位具有直接关系,应引起法医临床学鉴定人的重视。     

“洋货”观照下的“故物”——中国近代论评法家“法治”思想的路向与歧见

在中国"传统内"的释评系统中,法家的"法治"思想这个"故物",没有得到新的阐述与发展。到了近代,西方法治思想这个"洋货"成为重新解读"故物"的利器。但梁启超与萧公权同样用"洋货"观照"故物",却得出了法家"法治"思想之"真"与"伪"的不同结论。用"洋货"观照"故物",已成为具有重大影响与意义的思想学术路向,但也应克服其"强为比附"的结习。     

Occlusion of left and right coronary arteries and coronary sinus following blunt chest trauma

Blunt chest trauma from rapid automobile airbag deployment causing coronary artery occlusion and myocardial infarction is a rare but potentially fatal condition. We present the case of a 37-year-old man who developed extensive anterior and inferior myocardial infarction because of occlusion of both left anterior and right coronary arteries following blunt injury to the chest in a car accident. The patient was scheduled for emergency coronary angiography but left and right coronary ostia were not cannulated because of thrombus formation probably. The patient died, and the autopsy revealed external compression by epicardial hematomas involving separately left and right coronary arteries and the coronary sinus without signs of coronary and/or aortic dissection. To our knowledge, this is the first case presenting occlusion of both coronary arteries secondary to blunt chest trauma causing acute myocardial infarction in a young man without signs of prior coronary artery disease.     

农村留守老年人群体养老困局及对策

人口老龄化已成为当今国际社会的一个重要问题,根据国际人口学界通行的老龄社会标准,我国已步入老龄化社会,而且老龄化水平增长幅度逐年增加。农村大量青壮年劳动力涌入城市形成的农村留守老人这一特殊群体更给养老带来了挑战。通过实证调查发现,农村留守老人养老中面临的问题是多方面的,但以经济困境最为突出,据此提出相应的对策。
