Immunohistochemical distribution of C-reactive protein in the hepatic tissue in forensic autopsy

Previously, we examined the expression of C-reactive protein (CRP) in hepatic tissues in fatal injuries (injury deaths) immunohistochemically, and classified the CRP distribution into three patterns: diffuse (D-) pattern, diffuse with strong positivity in the hepatic lobules; periportal (PP-) pattern, characterized by positive cells in the periportal region of some lobules; focal (F-) pattern, showing small islands of positive cells in some lobules. There was a relationship between the CRP distribution and the survival time. In this study, we further analyzed the deaths including those due to other than fatal injuries (non-injury deaths), and a study of a total of 314 deaths from various causes was performed. Generally, non-injury deaths showed findings similar to those in injury deaths. PP- and/or F-patterns were observed in 43.7% of cases having a short survival time (<6 h), but found in only 3% of those surviving longer (>6 h), showing that such findings are suggestive of a short survival time. D-pattern was found more frequently in non-acute deaths (60.4%), than in acute deaths (10.9%). In acute deaths, D-pattern was found in some cases showing extensive tissue injuries, such as burns and polytrauma, and inflammative predisposition. Immunohistochemical findings also showed some correlation with the serum CRP level. Our data suggest that hepatic CRP immunohistochemistry may be a useful tool for elucidating the dying process.     

Immunohistochemistry of pulmonary surfactant apoprotein A in forensic autopsy: reassessment in relation to the causes of death

To reassess the immunohistochemical distribution of pulmonary surfactant apoprotein A (SP-A) in relation to the causes of death, 282 forensic autopsy cases were reviewed. The most intense and dense granular immunostaining of intra-alveolar SP-A was observed in the hyaline membrane syndrome from various traumas, protracted death from drowning, and perinatal aspiration of amniotic fluid. Similar granular staining pattern was found in fatal poisoning by a muscle relaxant and organophosphate pesticides. An evident increase of intra-alveolar granular staining was noted in most fatalities from mechanical asphyxia and drowning, and some cases of fire death. SP-A staining was usually very weak or sparse in alcohol intoxication, poisoning by hypnotics and also carbon monoxide poisoning. These findings suggest that the amount of intra-alveolar granular SP-A staining may be a possible indicator of severity and duration of respiratory distress (agony) from peripheral (non-central nervous system) origin and alveolar damage.     

Pulmonary surfactant-associated protein A levels in cadaveric sera with reference to the cause of death

Pulmonary surfactant-associated protein A (SP-A) is an exclusively lung specific protein, and is considered to leak into the blood stream in alveolar septal damage. In this study we examined the serum SP-A level in forensic autopsy materials using an enzyme immunoassay with monoclonal antibodies to assess the postmortem level in relation to the cause and mode of death. Although a gradual postmortem degradation should be taken into consideration, topological relationship of serum level seemed to be fairly stable (arterial> or =venous blood in most cases), indicating no evident influence of postmortem diffusion. Significant elevation of serum SP-A (76.7-250 ng/ml in left heart blood) was observed in hyaline membrane diseases from various causes independent of the postmortem intervals (<30 h). However, mean SP-A levels in postmortem heart blood were usually low in asphyxia including hanging, strangulation and choking (left, 25.5 ng/ml; right, 22.3 ng/ml), polytrauma (left, 13.1 ng/ml; right, 9.0 ng/ml) and stab wound to the neck (left, 34.1 ng/ml; right, 29.4 ng/ml). Prominent elevation was noted in a case of fatal strangulation with complication of idiopathic interstitial pneumonia, and also in some deaths due to drowning, burns in fires, blunt and gunshot chest injuries. These findings indicated that postmortem elevation of serum SP-A levels was associated with alveolar septal damage due to inflammation, mechanical and physical stresses, which caused leakage of SP-A into the bloodstream.

“非对称制华”——论日本海上战略新思维

东亚地缘政治形势自2010年起急剧变化。以此为背景,日本对华威胁感知急剧升高,维系日美同盟的需求更加紧迫,扩充本国自主防卫力的意愿更为强烈。受此推动,日本海上战略加速转型,出现了所谓“非对称制华”新思维。它以中美西太两极对峙和对华长期战略竞争为预设,以维持日美同盟西太制海权和防控危机升级为目标,谋求依靠“扬长避短”的策略来扭转自身的资源与能力劣势。同时它希望借助威胁中国的战略软肋以最终夺回中日海上军事较量的主动权。其中“拒止+控制”的作战构想与“成本强加”的威慑构想是两大基本组件。中国应据此反思自身海上战略目标,增强战略弹性,管控行动成本,强化和对手进行长期竞争的能力。
