法医解剖案例心、肺质量的统计分析及法医学意义

Statistical Analysis of the Heart and Lung Mass in Forensic Anatomical Cases and Its Forensic Significance

目的研究尸体解剖案例心、肺质量的差异,探讨心、肺质量在法医学鉴定中的应用价值。方法收集中国医科大学法医司法鉴定中心2007-2016年受理的尸体解剖案例1614例,采用GraphPad Prism6.0软件分析心、肺质量与年龄、身高、体质量及人体质量指数(body mass index,BMI)的相关性,以及在不同死因中的差异。结果男性心、肺质量均高于女性(P<0.05)。男、女性心脏质量均与年龄、身高、体质量及BMI呈正相关(P<0.05)。心脏性猝死者的心脏质量高于其他各死因者,溺死、迁延死者双肺质量高于其他各死因者(P<0.05)。结论在法医学鉴定实践中,测量心、肺质量对不同死因的诊断及鉴别诊断具有一定的意义。

Objective To investigate the differences of heart mass and lung mass in forensic autopsy cases and to explore their application value in forensic identification. Methods The data from 1 614 autopsy cases accepted by center of Medico-legal Investigation of China Medical University between2007 to 2016 were collected. The correlation of heart and lung mass with age, height, body weight,and body mass index(BMI), as well as differences in different causes of death were analyzed by GraphPad Prism 6.0 software. Results The heart mass and lung mass of males were higher than those of females(P<0.05). The heart mass of males and females was positively correlated with age, height,body weight and body mass index(BMI)(P<0.05). The heart mass of patients dying from sudden cardiac death(SCD) was significantly higher than those dying from other causes of death. The lung mass of patients dying from drowning and delayed treatment was higher than those dying from other causes of death(P<0.05). Conclusion In forensic practice, measurement of the heart mass and lung mass has certain significance for differential diagnosis and diagnosis of different causes of death.
