ABSTRACT
OBJECTIVES@#To promote the further research on body stature estimation and the innovative applications based on the distances between the anatomical landmarks on body torso surface.@*METHODS@#A specification for the collection of distances between the anatomical landmarks on body torso surface was established. The data of 933 cases of adult population in Yangtze River Delta region were collected. Multiple linear regression method was used to statistical analyse and establish the regression equation of stature estimation.@*RESULTS@#A regression equation about 5 variables including gender （x₁）, cervical vertebrae-coccyx line （x₂）, sterna-pubis line （x₃）, distance between acromion and iliospinale anterius （x₄） and shoulder breadth （x₅）, and stature （y） was established, y=105.406+5.414 x₁+0.436 x₂+0.286 x₃+0.225 x₄+ 0.193 x₅.@*CONCLUSIONS@#The method is suitable for the rapid, simple and accurate estimation of stature for the forensic experts.

Individual stature estimation is one of the most important contents of forensic anthropology. Currently, it has been used that the regression equations established by the data collected by direct measurement or radiological techniques in a certain group of limbs, irregular bones, and anatomic landmarks. Due to the impact of population mobility, human physical improvement, racial and geographic differences, estimation of individual stature should be a regular study. This paper reviews the different methods of stature estimation, briefly describes the advantages and disadvantages of each method, and prospects a new research direction.

OBJECTIVE@#To discuss and summarize the major characteristics, autopsy examination, and scene investigation in infant homicide cases.@*METHODS@#From 2008 to 2013 in Suzhou, the information of seven detected infant homicide cases were collected and analyzed.@*RESULTS@#The criminal suspects were victims' mothers with young ages and pregnancies were premarital. Infant homicide cases occurred at the same location of the delivery. The infants died of mechanical asphyxia in the majority of the cases. Most bodies were naked and their umbilical cords were not cut by iatrogenic method and didn't connect with the bodies.@*CONCLUSION@#The standardization of forensic investigation can improve the analysis and detection of infant homicide cases.

OBJECTIVE@#To explore the general features and the keypoints of forensic medical examination in tumbling injury cases.@*METHODS@#Twenty-eight cases dying of tumbling injury were collected and the locations and features of injury were analyzed.@*RESULTS@#The occiput of head was the common position for the tumbling injury cases. Force, disease and alcohol were the main reasons for tumbling injury.@*CONCLUSION@#The injury is mild outside and severe inside from tumbling injury cases. The craniocerebral contrecoup is the significant feature in tumbling injury cases.

OBJECTIVE@#This study aimed to clarify the morphology of the Martin-Gruber anastomosis (MGA) in Chinese.@*METHODS@#One hundred and five Chinese upper limbs (36 males and 20 femalese) were dissected to find the connections between medial nerve and ulnar nerve. The MGA was classified as previously described by Lee.@*RESULTS@#MGA was found in 24 cases (22.9%), in 11 of the 36 male and 5 of the 20 female. There was no obvious difference in the frequency of MGA in both upper limbs. Most MGA ulnar position was located at the medial and distal segment of the forearm.@*CONCLUSION@#MGA anatomy could play important role in forensic diagnosis of ulnar nerve injury in Chinese population.

OBJECTIVE@#To study the relationship between postmortem interval and the myofibril fragmentation index of skeletal muscle.@*METHODS@#Rabbit skeletal muscle were left in the room temperature for different postmortem intervals, and the protein concentration of each sample was detected by using biuret method. Furthermore, the myofibril fragmentation index of each sample was measured under the protein concentration level of 0.5 mg/mL.@*RESULTS@#The myofibril fragmentation index increased obviously according to the postmortem interval prolongation.@*CONCLUSION@#The myofibril fragmentation index may be used on the estimation of early postmortem interval.
