Sex determination by discriminant analysis of calcaneal measurements on the lateral digital radiography / 法医学杂志

OBJECTIVE@#Five measurements of the calcaneus taken on digital radiography (DR) of adults of Han Population of Sichuan Province were selected to determine sex by multivariate discriminant analysis.@*METHODS@#Lateral radiographs of calcaneus taken from 393 subjects were collected. The samples were randomly divided into the experimental group (148 males and 186 females) and the examined group (26 males and 33 females). Five measurements were taken from the radiography. The analysis of variance (AVON) was carried out to determine if there was significant difference between the male and female. The discriminant functions were drawn by Fisher discriminant analysis. The effects of all obtained functions were evaluated with the examined samples.@*RESULTS@#There was statistically significant difference in the five measurements between the males and the females (P<0.05). Six groups of discriminant functions were obtained with an accuracy ranged from 78.4% to 88.9%. When applied on the examined samples, the sex discriminant accuracy varied from 79.7% to 86.4%.@*CONCLUSION@#These five measurements acquired from the lateral radiographs of calcaneus could be used for sex assessment during forensic identification of individuals.

Relationship between chronic hepatitis C and type II diabetes mellitus / 中华实验和临床病毒学杂志

<p><b>BACKGROUND</b>To study the relationship between HCV infection and the development of type II diabetes mellitus.</p><p><b>METHODS</b>1. The case record files of 126 patients with chronic hepatitis C vs. 227 with chronic hepatitis B were reviewed and the laboratory and demographic data were extracted. 2. Anti-HCV and HBsAg were determined for 160 type II diabetes patients and 223 healthy adults by ELISA.</p><p><b>RESULTS</b>1. The occurrence of diabetes in patients with chronic hepatitis C was 19.05%, higher than 8.37% in patients with chronic hepatitis B (P<0.01). Age and HCV infection were independent risk factors for diabetes. 2. Five patients with type II diabetes were anti-HCV positive (3.12%) while none of the 223 healthy adults was anti-HCV positive (P<0.05). Seven patients with diabetes (4.37%) and 12 healthy adults (5.38%)were HBsAg positive (P>0.05).</p><p><b>CONCLUSIONS</b>1. The occurrence of diabetes was significantly higher in patients with HCV related liver disease than in patients with HBV related liver disease. 2. The occurrence of anti HCV was higher in diabetes patients than in healthy adults. HCV may play a role in the development of diabetes mellitus.</p>
