Video-assisted thoracoscopic surgery for penetrating thoracic trauma / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>For penetrating thoracic trauma, there is no consensus on whether operative exploration or conservative treatment is better. In this study, we compared the clinical effect of video-assisted thoracoscopic surgery (VATS) and thoracotomy on the patients with penetrating thoracic trauma.</p><p><b>METHODS</b>From January 2000 to December 2010, 123 patients with penetrating thoracic trauma were treated in Affiliated Hospital of Chengdu University. Based on the inclusion criteria, 80 patients were enrolled and randomly assigned into VATS and thoracotomy group.</p><p><b>RESULTS</b>The operation time, amount of bleeding and drainage in VATS group were all lower than traditional operation (p < 0.05).</p><p><b>CONCLUSION</b>The results indicate that VATS has the merits of shorter operation time, non-blind area, exact surgical path and less bleeding comparing with traditional operation.</p>

DNA Extraction of Cast-off Cells of Fingerprints from 502 Glue Fumigated Contact Samples / 法医学杂志

OBJECTIVE@#To establish a method of fingerprint position, sample transfer and fingerprint DNA extraction in contact samples.@*METHODS@#Sixty-six cases were visualized by 502 glue fingerprint fumigation. Two methods, ordinary wipe and acetone wipe, were used to transfer cast-off cells of fingerprints from testing samples, respectively. DNA was extracted and purified by ultramicro magnetic bead kit. The data was resolved on genetic analysis after amplification.@*RESULTS@#In 33 samples, 30 samples got better STR analysis by acetone wipe method. The peak range was 1,000-4,000 RFU and peak shapes were equable. It was hard to get ideal STR typing by ordinary wipe method.@*CONCLUSION@#The samples are visualized by 502 glue fingerprint fumigation and the case-off cells are transferred by acetone wipe method. The method shows better STR analysis result, which might be a better method for forensic science practice.
