【摘要】 伤病共存案件的死因鉴定是法医病理学检验中的难点。本文选取中山大学法医鉴定中心2013～2021年受理的各类伤病共存案例140例进行回顾性分析。研究发现，伤病共存案件占同期死因鉴定案件总数的2.89%，男、女性别比5.09。参与死亡的疾病中，心血管疾病达71.43%，冠心病占49.29%。三种伤病关系类型中，疾病为主，损伤为辅的占比超一半（65.86%），伤病同等作用的占比最少（12.14%）。案件医疗救治比例高达82.86%。重新鉴定占比10.71%，其中伤后24 h内死亡的重新鉴定案例占比达53.33%，远高于该存活时间在初次鉴定案中20.80%的占比（χ~2=13.84,P=0.000 2）。本研究揭示了伤病共存案件的流行病学特征，为提高该类案件的鉴定水平提供了科学数据。更多还原

【Abstract】 It is a challenge to determine the cause of death in cases caused by both injury and disease in forensic pathology examinations. Here, we retrospectively analyzed 140 such cases enrolled in the Sun Yat-sen University Forensic Identification Center from 2013 to 2021. It was found that the cases caused by both injury and disease accounted for 2.89 % of the total number of cases during the same period. The male-to-female ratio was 5.09.Cardiovascular disease accounted for 71.43 % of the death-leading diseases, and coronary heart disease accounted for 49.29 %. Among the three types of injury and disease relationship, the proportion of disease-based and injuryassisted cases accounted for more than half(65.86 %), and the proportion of injury and disease with the same effect cases was the least(12.14 %). Medical treatment was involved in as more as 82.86 % of the cases. Re-identification were carried out in 10.71 % of the cases, 53.33 % of which were with a ≤ 24-hour-survival time, higher than the proportion(20.80 %) of this survival time in initial identification cases(χ~2 = 13.84, P = 0.000 2). This study revealed the epidemiological characteristics of cases caused by both injury and disease, and supplied useful data for improving the level of forensic identification in such cases.更多还原
