Objective To investigate the frequency of staging behaviors involved in intimate partner homicide cases,as well as their correlation with the nature of death,medico-legal characteristics,and their correspondence with real causes of death.In order to improve the forensic understanding of staging behaviors in intimate partner homicide cases.Methods Using 100 investigated intimate homicides,forensic elements were statistically analyzed.The Chi square test was used to analyze the correlation between staging behavior and intimate partners,cause of death,injury weapons,time of death,degree of injury,resistance injury,postmortem intervals,and other specific elements and the occurrence of staging behavior.The corresponding partner between staging cause of death and real cause of death was clarified.Results Among the 100 intimate partner homicides,22 involved staging behaviors.Out of 10 cases of"staging"suicide,6 cases(60%)were attributed to staged causes of death.Among the 12"accidental"cases,there were 10 cases(83.33%)of staged causes of death.Staging manner of death appeared in 3 cases(30%)of"suicide"cases,and there was only one in"accidental"case(8.3%).The proportion of staged causes of death in strangulation cases was relatively high(35.71%,10/28).In cases with mild damage,the proportion of staging causes of death is higher(15/46).In cases without defense injuries,the proportion of staged causes of death was 23.19%(16/69).Among the true causes of death,strangulation in homicide was most commonly staged.Conclusion Different relationships of intimate partners did not affect the occurrence and distribution of staging behaviors.In cases involving staging behavior,the number of cases with staging as"accidental"nature of death is higher than that of"suicide"cases.The deaths with minor surface injuries such as strangulation and poisoning can be easily staging as suicide or accident.

On September 7th, 2017, one female patient, aged 48 years with deep partial-thickness flame burn on face, upper limbs, trunk, and lower limbs of 40% total body surface area was admitted to the First People′s Hospital of Foshan City. After admission, active fluid replacement, anti-infection, nutritional support, and other treatments were performed. After debridement and skin grafting for 3 times and blood transfusion for 2 times, the patient recovered well. On the 20th day post admission, sudden heartbeat and respiratory arrest happened, and the patient died after ineffective rescue. Autopsy showed that thrombus formed in right internal jugular vein and deep veins of lower extremities, and vascular lumina of the bilateral pulmonary artery. The direct cause of death was acute pulmonary thromboembolism, but whether the embolus originated from deep vein of lower extremity or right internal jugular vein was not clear. This case suggests that clinician should not only pay attention to the prevention of deep venous thrombosis of lower extremities of burn patients, but also the possibility of internal jugular vein thrombosis, especially for patients with internal jugular vein access.

OBJECTIVE: To analyze the morphological features and forensic pathological characteristics of cardiac ruptures of different causes for their differential diagnosis. METHODS: We analyzed the data of 44 autopsy cases of cardiac rupture from 2014 to 2017 in our institute, including 11 cases caused by blunt violence with intact pericardium, 4 caused by cardiopulmonary resuscitation (CPR), 9 by myocardial infarction, and 20 by aorta dissection rupture.The gross features and histopathological characteristics of cardiac rupture and pericardial effusion were analyzed and compared. RESULTS: Cardiac ruptures caused by blunt violence varied in both morphology and locations, and multiple ruptures could be found, often accompanied with rib or sternum fractures; the volume of pericardial effusion was variable in a wide range; microscopically, hemorrhage and contraction band necrosis could be observed in the cardiac tissue surrounding the rupture.Cardiac ruptures caused by CPR occurred typically near the apex of the right ventricular anterior wall, and the laceration was often parallel to the interventricular septum with frequent rib and sternum fractures; the volume of pericardial blood was small without blood clots; microscopic examination only revealed a few hemorrhages around the ruptured cardiac muscular fibers.Cardiac ruptures due to myocardial infarction caused massive pericardial blood with blood clots, and the blood volume was significantly greater than that found in cases of CPR-induced cardiac rupture ( < 0.05);lacerations were confined in the left ventricular anterior wall, and the microscopic findings included myocardial necrosis, inflammatory cell infiltration, and mural thrombus.Cardiac tamponade resulting from aorta dissection rupture was featured by massive pericardial blood with blood clots, and the blood volume was much greater than that in cases of cardiac ruptures caused by blunt violence, myocardial infarction and CPR ( < 0.05). CONCLUSIONS Hemorrhage, inflammatory cell infiltration, and lateral thrombi around the cardiac rupture, along with pericardial blood clots, are all evidences of antemortem injuries.
