ABSTRACT
OBJECTIVE@#To explore relationship between increase of fibrous and fatty in atrioventricular node (AVN) and narrowing of the AVN artery. To analyze the cause of pathological fibrosis and fatty infiltration in AVN.@*METHODS@#One hundred and nineteen cases of sudden cardiac death determined by autopsy were selected and the histological sections were examined with Image-pro plus software to calculate the AVN area, AVN artery inside-diameter, AVN artery lumen area(LA) , AVN artery perimeter area(PA), fibrous area and fatty area. All cases were divided into two groups: narrowing of artery group and normal control group. The changes of the PA/LA value and the fibrous and fatty contents were evaluated.@*RESULTS@#The PA/LA value is the highest in 21-40 age group. The difference of the fatty contents and total interstitial tissue was statistical significance in the two groups under 40 years of age.@*CONCLUSION@#There is some relationship between the narrowing of the AVN artery and the increase of interstitial contents in AVN.

In recent years, the traffic accidents increased gradually, especially those caused by the drivers daily emotional abnormality and in which the drivers were liable. This article reviewed the traffic accidents caused by divorced driver's emotional abnormality, illustrated the features of those accidents from the gender, age, occupation and mileage of drivers. It was considered that the major cause of those accidents was excessive drinking due to drivers' emotional stress. Suggestions about preventing the traffic accidents caused by emotional abnormality were put forward so as to make the corresponding rules and finally decrease the emotional abnormality traffic accidents.

Individual response to drugs, toxicants, environmental chemicals and allergens varies with genotype. Some respond well to these substances without significant consequences, while others may respond strongly with severe consequences and even death. Toxicogenetics and toxicogenomics as well as pharmacogenetics explain the genetic basis for the variations of individual response to toxicants by sequencing the human genome and large-scale identification of genome polymorphism. The new disciplines will provide a new route for forensic specialists to determine the cause of death.

Autopsy by forensic pathologist is a main mean currently to determine the cause of sudden unexpected death. Retinal examination is important but seldom performed during a forensic autopsy for various reasons. The value of retina examination has not been recognized. With invention of ophthalmic endoscopy and its subsequent application in postmortem retina examination, it has proved to be useful adjunct to determine the cause of death and to estimate the postmortem interval.

Multislice spiral computed tomography (MSCT) and magnetic resonance imaging (MRI) are useful to analyze cervical injury. Especially in injury of skeleton and soft tissue, it has equal value with conventional autopsy. Even they can reparation some shortcoming consisted in the cervical part autopsy. In some difficult postmortem examination of decomposed, charred or highly infectious cadavers and in some religion country, they should be a useful alternative way to examine injury in cervical part of cadaver such as mechanical asphyxia, whiplash injury, vertebra injury, or vascular injury.
