| 1 | Fibrinogen degradation product levels on arrival for trauma patients requiring a transfusion even without head injury显示文摘BACKGROUND: There have been few reports on the clinical significance of the fibrinogen degradation product(FDP) level in trauma patients with and without head injury. We retrospectively analyzed trauma patients with or without head injury to investigate the clinical signifi cance of the FDP level.METHODS: From April 2013 to June 2015, a medical chart review was retrospectively performed for all patients with trauma. The exclusion criteria included patients who did not receive a transfusion. The patients were divided into two groups: a FDP>100 group, which included patients who had an FDP level on arrival over 100 ng/m L, and a FDP≤100 group.RESULTS: The ratio of open fractures and the prothrombin ratio in the FDP>100 group were significantly smaller than those observed in the FDP≤100 group. The average age, ratio of blunt injury, Injury Severity Score(ISS), volume of transfusion and mortality ratio in the FDP>100 group were signifi cantly greater than those in the FDP≤100 group. There was a weakly positive correlation between the FDP level and ISS(R=0.35, P=0.002), but it was not associated with the transfusion volume. The results of an analysis excluding patients with head injury showed a similar tendency.CONCLUSION: The FDP levels may be a useful biochemical parameter for the initial evaluation of the severity of trauma and mortality even in blunt traumatized patients without head injury or with stable vital signs. | Youichi Yanagawa Kouhci Ishikawa Kci Jitsuiki Toshihiko Yoshizawa Yasumasa Oodc Kazuhiko Omori Hiromichi Ohsaka | 2017 | World Journal of Emergency Medicine2017，8，2： | 4 |
| 2 | Field observations of debris-flow initiation processes on sediment deposits in a previous deep-seated landslide site显示文摘Although information regarding the initiation processes of debris flows is important for the development of mitigation measures,field data regarding these processes are scarce.We conducted field observations of debris-flow initiation processes in the upper Ichinosawa catchment of the Ohya landslide,central Japan.On 19 June 2012,our videocamera monitoring systems recorded the moment of debris-flow initiation on channel deposits(nine surges) and talus slopes(eight surges).The initiation mechanisms of these surges were classified into three types by analyzing the video images: erosion by the surface flow,movement of deposits as a mass,and upward development of the fluid area.The first type was associated with the progress of surface flow from the upper stream on unsaturated channel deposits.The second type was likely caused by an increase in the pore water pressure associated with the rising in the groundwater level in channel deposits;a continuous water supply from the upper stream by the surface flow might have induced this saturation.The third type was associated with changes in the downstream topography caused by erosion.The flow velocity of most surges was less than 3 m s^(-1) and they usually stopped within 100 m from the initiation point.Surges with abundant pore fluid had a higher flow velocity(about 3- 5 m s^(-1)) and could travel for alonger duration.Our observations indicate that the surface flow plays an important role in the initiation of debris flows on channel deposits and talus slopes. | Fumitoshi IMAIZUMI Satoshi TSUCHIYA Okihiro OHSAKA | 2016 | Journal of Mountain Science2016，13，2： | 4 |
