Purpose： Early diagnosis of traumatic brain injury （TBI） is important for improving survival and neurologic outcome in trauma victims. The purpose of this study was to assess whether Glasgow Coma Scale （GCS） of 12 or less can predict the presence of TBl and the severity of associated injuries in blunt trauma patients. Methods： A retrospective cohort study including 303,435 blunt trauma patients who were transferred from the scene to hospital from 1998 to 2013. The data was obtained from the records of the National Trauma Registry maintained by Israel＇s National Center for Trauma and Emergency Medicine Research, in the Gertner Institute for Epidemiology and Health Policy Research. All blunt trauma patients with GCS 12 or less were included in this study. Data collected in the registry include age, gender, mechanism of injury, GCS, initial blood pressure, presence of TBI and incidence of associated injuries. Patients younger than 14 years old and trauma victims with GCS 13-15 were excluded from the study. Statistical analysis was performed by using Statistical Analysis Software Version 9.2. Statistical tests performed included Chi-square tests. A p-value less than 0.05 was considered statistically significant. Results： There were 303,435 blunt trauma patients, 8731 （2.9%） of them with GCS of 3-12 that including 6351 （72%） patients with GCS of 3-8 and 2380 （28%） patient with GCS of 9--12. In these 8731 patients with GCS of 3-12, 5372 （61.5%） patients had TBI. There were total 1404 unstable patients in all the blunt trauma patients with GCS of 3-12,1256 （89%） patients with GCS 3-8, 148 （11%） patients with GCS 9-12. In the 5095 stable blunt trauma patients with GCS 3-8, 32.4% of them had no TB1. The rate in the 2232 stable blunt trauma patients with GCS 9-12 was 50.1%. In the unstable patients with GCS 3-8, 60.5% of them had TBI, and in subgroup of patients with GCS 9-12, only 37.2% suffered from TBI. Conclusion： The utility of a GCS 12 and less is limited in prediction

本文研究了啤酒成分中分子量范围对口味醇厚度的影响.采用AF4/MALLS/RI联用技术测定了不同麦芽糊精添加到9种比尔森啤酒中的分子量范围.感官分析由德国农业协会品尝小组完成.本文还测定了啤酒加麦芽糊精后的口味醇厚度和啤酒中麦芽糊精的阈值.研究了比尔森啤酒成分的分子量范围与口味醇厚度的相关性.使用AF4/MALLS/RI和感官分析研究了酿造过程中的变化对啤酒成分分子量范围和口味醇厚度的影响.比尔森啤酒的口味醇厚度存在显著的不同（p＞0.0001）.商品啤酒中的分子量范围与口味醇厚度存在很强的相关性（p＞0.05）.比尔森啤酒的分子量范围（3-13 kDa）与中等分子量的糊精相符,较低分子量范围（2.7-8.9 kDa）的糊精具有更高的浓度阈值.库尔巴哈值为36％的麦芽酿造的啤酒（2.9-13 kDa）较库尔巴哈值为41％的麦芽酿造的啤酒（1.7-11.6 kDa）具有更高的分子量范围.使用库尔巴哈值为36％的麦芽,糖化的起始温度变化和生产啤酒口味醇厚之间的差别很小,而用库尔巴哈值为41％的麦芽生产的啤酒之间则显示差别比较明显（P＜0.0001）.糖化和麦芽质量的变化和能改变啤酒成分的分子量分布范围,进而影响比尔森啤酒的口味醇厚度.

A search for the doubly charmed baryon ■^+cc is performed through its decay to theΛ^+c K^-π^+ final state,using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7,8 and 13 *** data correspond to a total integrated luminosity of 9 fb^-*** significant signal is observed in the mass range from 3.4 to 3.8 GeV/c^*** limits are set at 95%credibility level on the ratio of the ■^+cc production cross-section times the branching fraction to that ofΛ^+c and ■^++cc *** limits are determined as functions of the ■^+cc mass for different lifetime hypotheses,in the rapidity range from 2.0 to 4.5 and the transverse momentum range from 4 to 15 GeV/c.
