ABSTRACT
Objective To construct the clinical database on pelvic trauma life cycle so as to provide reference for epidemiological investigations and development of pelvic damage control plan. Methods The existing pelvic trauma data of the hospital information system was analyzed to discuss the main evaluation indicators and data types at different stages, including basic data, injury severity index, underlying disease, fracture classification, specialist treatment, rehabilitation and follow-up information. Results Based on the V3.0 trauma scoring system, the clinical pelvic trauma ACCESS database was developed. The data of 588 patients with pelvic trauma were collected from November 2007 to May 2009 and preliminarily analyzed. Conclusions Clinical database of pelvic trauma can be used as the specific modules of general network trauma database system and a large-scale, multi-center and standard pelvic trauma database may play an important role in preparation of the prospective damage control plans.
ABSTRACT
Objective To investigate the dynamics of the level of S100 in cerebrum, brainstem, and serum following the diffuse brain injury in rats and provide the experimental evidences for estimating injury time. Methods ELISA was used to determine whether S100 protein is changed after diffuse brain injury in rats. Forty rats were sacrificed at 0.5 hour, 2 hours, 4 hours, 12 hours, 24 hours, 3 d and 7 d after diffuse brain injury and normal rats as control. Results The level of S100 in cerebrum, brainstem, and serum increased, followed by a decrease, and then further increased. The level of S100 could be detected to increase at 30 minutes and reached the peak at 4 hours after DBI. The level decreased gradually to the normal at 1d and till 3 d formed the second peak. The level returned to the normal at 7d following injury again. In the postmortem injury groups, there were no significant changes compared to the control group. Conclusion The present study showed that the time-dependent expression of S100 is obvious following diffuse brain injury in rats and suggested that S100 will be a suitable marker for diffuse brain injury age determination.
