| 1 | State of the art in post-mortem forensic imaging in China显示文摘The autopsy and histopathologic examination are traditional and classic approaches in forensic pathology.In recent years,with the tremendous progresses of computer technology and medical imaging technology,the developed post-mortem computer tomography,post-mortem magnetic resonance imaging and other new methods provide non-invasive,intuitive,high-precision examining methods and research tools for the forensic pathology.As a result,the reconstruction of the injury as well as the analysis of injury mechanism has been essentially achieved.Such methods have become popular in the research field of forensic science and related work has also been carried out in China.This paper reviews the development and application of abovementioned post-mortem forensic imaging methods in China based on the relevant literature. | Yijiu Chen | 2017 | Forensic Sciences Research2017，2，2： | 4 |

| 3 | Diagnosis of coronary artery disease using targeted post-mortem computed tomography coronary angiography:a case report显示文摘Targeted post-mortem computed tomography(PMCT)combined with coronary angiography has the potential to play a significant role in the investigation of sudden cardiac death.The authors utilized a targeted PMCT coronary angiography in a case involving a 53-year-old man who died from acute myocardial ischemia and cardiac decompensation which may result from coronary artery disease(CAD).The victim collapsed suddenly at work and died soon after arrival to hospital.The body was examined using PMCT and targeted PMCT coronary angiography.The left anterior descending coronary artery exhibited 75%-100%stenosis in the middle segment;however,the distal segment could not be clearly visualized.In addition,the left circumflex and right coronary artery exhibited calcification,atherosclerosis and an area of 50% stenosis.Signs of cardiogenic pulmonary oedema were also identified.The imaging results suggested that this individual had coronary atherosclerosis and probably died from CAD.The autopsy and histological examination revealed acute myocardial ischemia and myocardial scarring,confirming the cause of death while excluding other probabilities.In summary,targeted post-mortem computed tomography angiography(PMCTA)can visualize the arteries and estimate the degree of principal pathological changes.This method is a simple,reliable and sensitive technique for identifying the presence of coronary atherosclerosis.It is a valuable post-mortem forensic imaging method and should be recommended in the investigation of suspicious cardiac deaths. | Lei Wan Yu Shao Donghua Zou Ping Huang Zhengdong Li Maowen Wang Yijiu Chen | 2017 | Forensic Sciences Research2017，2，2： | 2 |

| 9 | Use of deep learning in forensic sex estimation of virtual pelvic models from the Han population显示文摘Accurate sex estimation is crucial to determine the identity of human skeletal remains effectively.Here,we developed convolutional neural network(CNN)models for sex estimation on virtual hemi-pelvic regions,including the ventral pubis(VP),dorsal pubis(DP),greater sciatic notch(GSN),pelvic inlet(PI),ischium,and acetabulum from the Han population and compared these models with two experienced forensic anthropologists using morphological methods.A Computed Tomography(CT)dataset of 862 individuals was divided into the subgroups of training,validation,and testing,respectively.The CT-based virtual hemi-pelvises from the training and validation groups were used to calibrate sex estimation models;and then a testing dataset was used to evaluate the performance of the trained models and two human experts on the sex estimation of specific pelvic regions in terms of overall accuracy,sensitivity,specificity,F1 score,and receiver operating characteristic(ROC)curve.Except for the ischium and acetabulum,the CNN models trained with the VP,DP,GSN,and PI images achieved excellent results with all the prediction metrics over 0.9.All accuracies were superior to those of the two forensic anthropologists in the independent testing.Notably,the heatmap results confirmed that the trained CNN models were focused on traditional sexual anatomic traits for sex classification.This study demonstrates the potential of AI techniques based on the radiological dataset in sex estimation of virtual pelvic models.The excellent sex estimation performance obtained by the CNN models indicates that this method is valuable to proceed with in prospective forensic trials. | Yongjie Cao Yonggang Ma Xiaotong Yang Jian Xiong Yahui Wang Jianhua Zhang Zhiqiang Qin Yijiu Chen Duarte Nuno Vieira Feng Chen Ji Zhang Ping Huang | 2022 | Forensic Sciences Research2022，7，3： | 1 |

| 11 | Current state and progress of research on forensic biomechanics in China显示文摘Forensic biomechanics gradually has become a significant component of forensic science.Forensic biomechanics is evidence-based science that applies biomechanical principles and methods to forensic practice,which has constituted one of the most potential research areas.in this review,we introduce how finite element techniques can be used to simulate forensic cases,how injury criteria and injury scales can be used to describe injury severity,and how tests of postmortem human subjects and dummy can be used to provide essential validation data.This review also describes research progress and new applications of forensic biomechanics in China. | Yijiu Chen | 2021 | Forensic Sciences Research2021，6，1： | 1 |
