OBJECTIVES@#To study the distribution of total phosphine in phosphine poisoning victims and summarize the characteristics of phosphine poisoning cases.@*METHODS@#The phosphine and its metabolites in the biological samples of 29 victims in 16 phosphine poisoning cases were qualified and quantified by headspace gas chromatography-mass spectrometry.@*RESULTS@#Five victims among 29 were poisoned by ingestion of aluminium phosphide and 24 by inhalation of phosphine gas. Phosphine metabolites were detected in the biological samples of 23 victims, and the concentrations of total phosphine in blood ranged 0.5-34.0 μg/mL. The total concentration of phosphine in liver tissue was up to 71.0 μg/g. Phosphine was not detected in the blood of the other six survived victims, which may be related to the small amount of phosphine exposure and the delay in blood sampling.@*CONCLUSIONS@#The total concentration of phosphine in blood and tissues caused by aluminum phosphine ingestion is higher than that caused by phosphine gas inhalation. The death cases of phosphine inhalation are characterized by long exposure time, repeated exposures and age susceptibility.

OBJECTIVES@#To analyze the characteristics of thoracic aorta injury in road traffic accidents, to provide data reference for forensic identification.@*METHODS@#The data of 27 traffic accident death cases with thoracic aorta injury were analyzed according to relevant parameters including sex, age, mode of transportation, and thoracic aorta injury.@*RESULTS@#Aortic injury in traffic accidents was significantly more in males than females, and 74.1% cases were in the age range of 31-70 years. The most common mode of transportation was the motorcycle, followed by electric bike, most of which crashed with trucks. Most cases were accompanied by rib fractures and lung injuries. Thoracic aorta injury was the most common in ascending aorta, followed by aortic arch and thoracic aorta. Ascending aorta injury was most likely to occur in the range of 0-<1.6 cm from the aortic valve, while it was rare over 2.6 cm. Taking the aortic valve as the reference, the most common locations of injury were the anterior semilunar valve, followed by the right posterior semilunar valve and the left posterior semilunar valve. Thoracic aortic rupture occurred in 63.0% cases, and intima and media lacerations only occurred in 37.0% cases. A few deceased had aortic diseases.@*CONCLUSIONS@#The proximal part of the ascending aorta is prone to be injured because of the large external force of traffic accidents. The medical examiner should carefully examine the aortic injury in traffic accident deaths, and evaluate the relationship between the injury and the disease according to the condition and degree of aortic injury.

Objective To provide reference for medical and health services and forensic expertise, the causes and manners of death of psychiatric patients were analyzed retrospectively. Methods A total of 105 autopsy cases of psychiatric patients accepted and settled by Institute of Forensic Science of Criminal Investigation Police University of China from 2004 to 2019 were collected. The cases were divided into four groups: disease death, suicidal death, accidental death and homicidal death. The common causes of death of each group were statistically analyzed and the differences in age, disease duration, body mass index (BMI) and gender among the groups were assessed. Results Of the 105 cases, 60 were male and 45 were female, the course of psychosis was (12.9±10.4) years, the age of the deceased was (51.3±11.4) years, and 61.0% was schizophrenic. There were 50 cases (47.6%) in the disease death group, in which the psychiatric patients were the oldest and had the longest course of psychosis and lowest BMI. Pulmonary thromboembolism, respiratory infections, and cardiogenic disease were the most common causes of death in the group. There were 26 accidental deaths (24.8%), among which traffic accidents were the most common cause of death. There were 15 homicidal deaths (14.3%), all of which were male, with craniocerebral injury being the most common cause of death. There were 14 suicidal deaths (13.3%). In suicidal death group, the age of the deceased was the youngest, the course of psychosis was the shortest and falling from the height was the most common way to commit suicide. Conclusion Understanding the common causes of death of psychiatric patients may contribute to developing measures to reduce the mortality rate of the population. It is necessary to investigate the age, course of psychosis and gender of the deceased when assessing the manner of death.

Objective To retrospectively analyze the characteristics of the traumatic rupture of intracranial internal carotid artery in order to provide reference for forensic expertise examination and identification. Methods A total of 11 autopsy cases of traumatic rupture of intracranial internal carotid artery were collected. The gender, age, cause of injury, blood loss on the scene, location of internal carotid artery rupture, hardening degree of the rupture of the wall, brain injury, blood ethanol content and cause of death were also recorded. Results All 11 cases died on the scene, of which 7 died from traffic accidents, 2 falls from height and 2 from bare handed injuries. None of the 11 victims suffered serious head and body surface injury. The internal carotid artery rupture in the 9 cases of traffic injury and fall from height injury occurred in the cavernous segment. In all these cases, there were transverse fractures of the middle cranial fossa with the carotid sulcus involved, and minor intracranial hemorrhage and brain contusion. In 2 cases of bare handed injuries, internal carotid artery rupture occurred in the ophthalmic artery segment, accompanied by fatal intracranial hemorrhage and diffuse axonal injury, but no skull fracture. All 11 cases showed full-thickness rupture of the vessel wall, and the long axis of the wounds was perpendicular to those of the artery. Conclusion The incidence of intracranial internal carotid artery rupture in high-energy trauma events such as traffic accidents and high falls deserves attention. Injuries of the cavernous segment or ophthalmic segment might be more common. The main injury mechanism of intracranial internal carotid artery rupture might be that the blood vessels were pulled and the bone fragments caused damage.

Objective To test the feasibility and accuracy of with sarcosaprophagous insects postmortem interval (PMI) estimation with sarcosaprophagous insects and provide references for estimation practice. Methods Eleven cases confirmed by the detection results, with complete entomological evidence were selected. The insect species, estimation results and true results involved in the cases were statistically analyzed and compared. Results Thirteen species of insects were found at the criminal scene, including Chrysomya megacephala (Fabricius), Chrysomya rufifacies (Macquart), Chrysomya nigripes (Aubertin), Lucilia sericata (Meigen), Hydrotaea spinigera Stein, Muscina stabulans (Fallén), Sarcophagid (species were not identified), Megaselia scalaris (Loew), Hermetia illucens (Linnaeus), Saprinus splendens (Paykull), Creophilus maxillosus (Linnaeus), Dermestes maculatus (De Geer) and Necrobia ruficollis (Fabricius). The PMI of all eleven cases was within the range of estimated PMI. The estimated results of 72.73% cases were on the same day of the true results. Conclusion Sarcosaprophagous insects can estimate the PMI simply and conveniently. In cases where the PMI is within the time range of one generation of flies or beetles, the estimation results are relatively accurate. However, the estimation is less accurate when the PMI is beyond the time range.

Objective To retrospectively analyze 40 cases of hanging and 33 cases of ligature strangulation in Kunming, to explore the neck injury characteristics and similarities and differences of related asphyxia signs of corpses in hanging and ligature strangulation cases, in order to provide reference for forensic identification. Methods Statistics of hanging and ligature strangulation cases accepted by Kunming Municipal Public Security Bureau from 2000 to 2017 were collected. Data including the gender, age, injury tool, neck injury and related asphyxia signs of the deceased in hanging and ligature strangulation cases were statistically tested by SPSS 23.0. Results There were more males in hanging cases than females. However, there were more females than males in ligature strangulation cases. In hanging cases, suicide was common, while homicide was rare. In ligature strangulation cases, homicide was common, while suicide or accidental death was rare. The average age of the deceased in hanging cases were older than those in ligature strangulation cases. The ligature mark in hanging was usually above the thyroid cartilage. The ligature mark in ligature strangulation was usually at the same level of the thyroid cartilage. The most common vital reactions were exfoliation and subcutaneous hemorrhage at the ligature mark, common among the deceased in hanging cases. Hyoid fracture rate of the deceased in ligature strangulation cases was more common than those in hanging cases. Conclusion The gender, age distribution, position of ligature mark, detection rate of vital reactions at the ligature mark and hyoid fracture rate of the deceased can help distinguish hanging from ligature strangulation.

Objective To retrospectively analyze the forensic pathological postmortem examination and clinical data of children who died of viral pneumonia in identification of cause of death cases and to discuss the clinical characteristics and pathological features of viral pneumonia in children, in order to provide reference to pathological diagnosis of viral pneumonia in children caused by 2019 novel coronavirus (2019-nCoV) infection. Methods Postmortem examination data from 61 cases of children whose causes of death were identified as viral pneumonia in recent years were collected from the Center of Forensic Identification, Southern Medical University. The gender, age, clinical symptoms and pathological features were comparatively analyzed. Results Among the 61 cases of children who died of viral pneumonia, most were within 2 years old (83.61%), and a large proportion died within 2 weeks after the onset of the disease (91.80%). Gross changes in postmortem examination included respiratory mucosal hyperemia, pleural effusion, pulmonary swelling, variegated pulmonary pleura and serosa, as well as focal pulmonary hemorrhage and pulmonary edema. A large proportion of sick children had enlarged mesenteric lymph nodes (83.61%) and thymic dysplasia (21.31%). Histopathological changes included edema of alveoli and interstitial substance, pneumorrhagia,shedding of alveolar epithelial cells, serous and (or) fibrous exudation in the alveoli, formation of viral inclusions, formation of transparent membranes, infiltration of inflammatory cells that mainly consisted of macrophages and lymphocytes in interstitial substance and alveoli. Viral infections often affected the heart and gastrointestinal tract. Conclusion The clinical symptoms of children with viral pneumonia are difficult to notice, and because the immune systems of children are not fully developed and they have poor immunity, they can easily become severely ill and even die. Analyzing the forensic autopsies and the histopathological characteristics could provide reference for pathological diagnosis of viral pneumonia.

Objective To explore the consistency between identification diagnosis and pre-identification clinical diagnosis of patients with mental disorder undergoing forensic psychiatry identification. Methods The identification data of 1 369 appraised individuals who underwent criminal responsibility identification carried out by the Forensic Institute of Second Affiliated Hospital of Jining Medical University from 2014 to 2017 were collected retrospectively using self-designed investigation data sorting table. A comparative analysis of the mental disorder diagnosis results of expert opinion and past clinical diagnosis results was made. Results Among 1 369 appraised individuals, 964 cases (70.4%) were identified and diagnosed with mental disorder and 405 cases (29.6%) without mental disorder. Among the former, 63.3% (610 cases) were clinically diagnosed, which was higher than 43.2% (175 cases, P<0.05) in the latter. Among the various mental disorders that had been identified and diagnosed, patients with hysteria, stress, and neurosis had the highest proportion of clinical diagnoses (86.7%), while patients with mental retardation had the lowest proportion of clinical diagnoses (9.6%). Schizophrenia had the highest overall consistency rate of identification diagnosis and clinical diagnosis (98.4%), while personality and behavior disorder had the lowest (33.3%). The overall consistency rate between clinical diagnosis and identification diagnosis of the mental disorder group was 84.1%, and the Kappa value was 0.759. Compared with clinical diagnosis, the consistency rate between inpatient diagnosis and identification diagnosis was higher (85.9%, P<0.05). Conclusion In forensic psychiatry identification that provides data of past clinical diagnosis and treatment, a high consistency between identification diagnosis and clinical diagnosis of the appraised individual who is identified and diagnosed with mental disorder exists. Clinical diagnosis (especially the inpatient diagnosis) has a relatively good reference value for forensic psychiatry identification.

Objective To investigate the epidemiological and forensic characteristics of multiple organ dysfunction syndrome (MODS) after severe trauma and explore the reference indexes for determining traumatic MODS. Methods In terms of the number of organs or systems involved in MODS, the number of failures of each organ or system, the first failing organ and the survival time after organ failure, 72 cases of MODS death caused by traffic accidents were retrospectively analyzed. The cases were divided into two groups according to the mean injury severity score (ISS). The t test was used to analyze the differences in the number of organs or systems involved in MODS in the two groups. Chi-square test was used to analyze the differences in the types of first failing organs and the differences between the two groups in the number of cases of organ or system failure involved in MODS. Wilcoxon signed-rank test was used to analyze the differences between the two groups in survival time of MODS after trauma. Kaplan-Meier survival curve was drawn and Log-Rank test was performed. Results The number of MODS involved organs or systems after trauma in ISS≤35 group was 3-5, and 2-4 in the ISS>35 group (P<0.05). The cases of MODS organ or system failure after trauma occurred more in brain and lung in the two groups. The first failing organ after trauma was mainly the lung or kidney. The median time of first organ failure after trauma was 2.00 d, the median survival time of MODS after trauma in ISS≤35 group was 6.00 d, and 2.33 d in ISS>35 group (P<0.05). The survival curve of ISS≤35 group was relatively high and declined gradually, while the survival curve of ISS>35 group was relatively low and the decline was steep (P<0.05). Conclusion The epidemiological and forensic characteristics of MODS caused by traffic accidents have certain specificity. The ISS and the forensic characteristics of MODS at ISS>35 can be used as reliable reference indexes for evaluation of the causal relationship among trauma, MODS and death.

Objective To discuss the types, characteristics, and the evaluation of disability of knee injuries. Methods The data of 133 cases of knee injury from 2017 to 2019 were collected and statistically analyzed according to the region of injury, the degree of disability, etc. Results One hundred and twenty-five cases of injury were compound, and 8 cases were simple. The incidences of ligament injury, meniscus injury and fracture were 88.72%, 75.19% and 57.89%, respectively. Of the cruciate ligament injuries, 12 cases were posterior cruciate ligament injury while 51 cases were anterior cruciate ligament injury, and the differences between the two kinds of injury had statistical significance (P<0.05); 32 cases were secondary traumatic arthritis. The rates of disability of knee injuries were 38.35% (Grade Ⅸ and Ⅹ). Conclusion Compound knee injuries are common, and traumatic arthritis has a relatively high rate. Multiple injuries can affect the stability and weight-bearing of the knee joint. It is suggested that in addition to evaluating the range of motion of knee joint, multiple factors should be considered to assess disability.

Objective To explore the characteristics of individuals with mental disorders suspected of road traffic offences and to find their differences from normal offenders, in order to regulate mental disorder patients' driving activities and prevent road traffic offences. Methods One hundred and twenty-three cases of forensic psychiatry testimony of individuals suspected of road traffic offences between 2014 and 2019 from the West China Forensic Center of Sichuan Province were collected. Fisher exact probability test was used to compare the differences between offenders with mental disorders and without mental disorders in terms of demographic characteristics, criminological characteristics, psychiatric characteristics and criminal responsibilities. Results There was no statistical significance in the differences of demographic characteristics, vehicles and kinds of alcohol between the two groups (P>0.05). The main type of road traffic related crimes committed by offenders with mental disorders was risky driving and were mainly evaluated as partial criminal responsibility, whereas most offenders without mental disorders committed crime of causing traffic casualties and all were evaluated as full criminal responsibility. There was statistical significance in the differences of the types of crime and the criminal responsibility rating between the two groups (P<0.05). Meanwhile, patients with mental disorders were characterized by long course of disease and irregular treatment, and individuals diagnosed as having mental disorders caused by psychoactive substances accounted for a large proportion. Conclusion There are differences in the characteristics of road traffic-related crimes between mental disorder patients and normal people. It is of great practical significance for reducing road traffic offences to evaluate whether the individuals with mental disorders are fit for driving.

Objective To study the change trend, distribution characteristics and causes of medical malpractices in 18 years, through retrospective analysis of 1 900 cases of medical malpractices, in order to provide guidance for the precaution and the treatment of medical malpractices. Methods A thousand and nine hundred medical malpractice cases that were accepted by Hunan Xiangya Judical Identification Center from 2000 to 2017 were collected. Statistical analysis on the caseloads, the clients, the department distributions, the levels of the hospital and the causes of medical malpractices, etc were conducted. Results The number of cases commissioned by third-party accreditation agencies for medical fault identification was on the rise; The clients of medical malpractices changed significantly in 18 years. Most of the medical malpractice cases occurred in secondary and tertiary hospitals, significantly more in surgery, obstetrics and gynecology. The occurrence of medical malpractices was related to the doctor's insufficient prediction of the severity of the disease and the possible complications, and failure to fully inform the relevant duty of care, etc. Conclusion China's medical malpractice solutions and medical fault identification procedures are gradually improving. Strengthening the medical malpractice precaution awareness of medical workers in surgery, obstetrics and gynecology will be conducive to resolution of medical malpractices.

Objective To investigate the characteristics and patterns of factors such as victims' information, injury tools and time of occurrence of intentional injury cases in southwest China. Methods One thousand three hundred and forty intentional injury cases from several places in southwest China from 2014 to 2016 assessed as minor injury level Ⅱ and above had been randomly selected. Data on victims' information, motives, injury tools, sites of occurrence, time of occurrence, injured parts and degrees of injury were classified and gathered, and then association analyses of motives and types of injury tools as well as degrees of injury and injury tools were made. Results Most of the victims were young adults between 20-50 years (65.2%), male (82.3%), rural household registration (62.8%); the motives were mainly dispute (45.8%). Injury tools were mostly blunt (54.6%) or sharp (36.0%). Specifically, injuries were mostly made bare-handed (36.9%) and by cutting tools (33.2%); the cases mainly occurred in public areas (59.0%). Cases occurred more frequently in January (11.3%), February (13.1%), March (11.6%) and from 22:00 to 01:00 every night. Injuries mainly involved the craniofacial region. The wounds were mainly assessed as minor injury level Ⅱ (61.6%). There was statistical significance in the difference of types of injury tools among cases with different motives (P<0.05). There was statistical significance in the difference of the distribution of injury tools among cases with different degrees of injury (P<0.05). Conclusion The occurrence of intentional injury cases in southwest China has potential patterns and relevant influencing factors. Prevention and analysis of such cases need to be comprehensively considered from the aspects such as victims' information, injury tools and time of occurrence.
