简介：AbstractPurpose:Trauma has been called the neglected disease of modern society. According to WHO, fall is the second major cause of trauma or deaths resulting from unintentional accidents. The aim of this study was to investigate the different types of fall according to International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) in hospitalized patients visiting specialized accident and trauma hospitals of Mashhad, Iran.Methods:This was a cross sectional retrospective study performed between March 20, 2013 and March 20, 2014. The research population consisted of all medical records of patients for fall injuries in three specialized accident and trauma hospitals. ICD-10 was adopted to categorize all types of falls (w00-w19). The results obtained were analyzed by SPSS 16.Results:Altogether 7,448 cases were included. The codes w18 (fall on same level) and w09 (fall involving playground equipment) with the frequencies of 1,856 and 1,303, respectively in both genders had the maximum number of falls. The maximum percentage of mortality has been related to "fall on and from ladder" ," fall from cliff "and "fall on same level involving ice and snow" .Conclusion:As falls can cause irrecoverable injuries including mortality of people, thus health authorities and policymakers should take preventive measures given the causes of falls and the root of this type of injuries, so that the costs resulting from this cause and its injuries can be reduced.

简介：ObjectiveTrauma在在沙特阿拉伯的年轻年龄组之中是死亡和病态的领先的原因并且开发国家。这研究试图为临床的严厉作为一个潜在的预言者与创伤的大脑损害(TBI)在孩子评估血小板计数的秋天，outcome.MethodsTotally，有TBI的74个病人从开始2008年1月到目的进入我们的医院的小儿科的特别护理单位(PICU)2010年3月(27个月)。基线注册标准是很长时间12年，在在损伤事件以后的4个小时以内的承认，和缩短的损害规模(AIS)(或)，3.1；相对风险(RR)，2.15。接收装置操作特征(巨鸟)曲线和Youden索引证明PFP的最佳截止点在51.5%.ConclusionPFP与TBI的严厉被增加，它能也为它的结果作为一个重要独立预言因素被拿。

简介：目的：研究电针逆转血管紧张素-（17）[Ang-（1—7）]在大鼠延髓尾端腹外侧区（CVLM）引起血压降低的作用机制。方法：采用中枢核团微量注射和微透析，以及高效液相色谱（HPLC）荧光检测等技术观察Ang（17）及其选择性受体拮抗剂（D-Ala7）-Ang-（1—7）（Ang-779）在大鼠CVLM引起血压改变时氨基酸类神经递质释放的变化以及电针对血压和氨基酸类递质释放的影响。结果：在CVLM微量注射Ang（1—7）可引起血压降低，同时伴该区内兴奋性氨基酸谷氨酸（Glu）释放增多和抑制性氨基酸牛磺酸（Trau）释放减少；相反，在CVLM微量注射Ang779则可引起血压升高，同时伴Glu释放减少和Tau释放增多。在相当于人”足三里”穴位电针20min，可分别抑制在CVLM微量注射Ang—（1-7）或Ang779所引起的血压降低或升高，同时也能部分抵消注射Ang-（17）或Ang779所引起的Glu、Tau释放的改变。结论：电针逆转Ang（1-7）或Ang-779在CVLM引起的降压或升压作用可能与Glu、Tau释放量的改变有关。
