重型颅脑损伤患者血清血栓调节蛋白和血管性假血友病因子动态变化及其临床意义

Objective To investigate the changes of thrombomodulin (TM) and von Willebrand factor (vWf) and their clinical significance in patients with severe brain injury. Methods The study involved 62 patients with severe brain injury who were divided into diffuse axonal injury group (28 patients) and focal brain injury group (34 patients). Then, the 62 patients were divided into young group (16-30 years old, 20 patients), middle-aged group (31-65 years old, 20 patients) and elderly group ( ＞65 years old, 22 patients). The serum levels of TM and vWf were determined at days 1 and 7 after injury respectively. ELISA method was employed to determine the serum levels of TM and vWf.Results The vWf in focal brain injury group was significantly higher than that of diffuse axonal injury group at days 1-7 after injury ( P ＜ 0.05 ). Compared with the young and middle-aged groups, the TM and vWf levels in the elderly group at day 1 after injury were significantly elevated ( P ＜ 0. 05 ). The TM levels in patients with delayed traumatic intracerebral hematoma (DTICH) were significantly higher than that in patients without DTICH (P ＜ 0. 05). Conclusions In the acute stage of severe brain injury,injury severity and activation of endothelial cells varies in patients with different types of injury and at different ages. TM is one of sensitive indicators to reflect the cerebal vascular endothelial cell injury. It is very meaningful to assess the prognosis of severe brain injury by measuring serum levels of TM and vWf and take TM as a predictive indicator for DTICH.     

亚低温对急性重型颅脑损伤患者血清S-100 B蛋白的影响

Objective To dynamically observe the effect of mild hypothermia on concentration of plasma S-100B protein in patients with acute severe brain injuries so as to further explore its role in treat-ment of acute severe brain injury. Methods A total of 120 patients with acute severe brain injuries were randomly divided into mild hypothermia group and general group. The patients in mild hypothermia group were treated with mild hypothermia besides conventional therapy, with maintenance of rectal tem-perature at 33℃-35℃ for 3-5 days. Serial concentration of S-IOOB protein in serum was measured in all patients from 6 hours to 6 days after hospitalization. GOS evaluation was done three months after treat-ment. Results The concentration of S-100B protein in serum of mild hypothermia group and general group was significantly higher than of normal group (P <0.05), with significant lower level in mild hypo-thermia group than general group(P <0.05). Mild hypothermia could improve prognosis of patients with acute severe brain injury. Conclusions Early use of mild hypothermia can decrease concentration of S-100B protein in serum, protect neurofunction and improve prognosis, as may be related to its function in alleviating damnification brain cell inflammation reaction mediated by S-100B protein.

目的 探讨创伤早期促血管生成素-2(Ang-2)的变化及临床意义. 方法 遴选20～60岁、伤后1 h内就诊入院的多发伤患者45例,按损伤严重度评分(ISS)分为3组,入院后立即采血,对比分析各组血浆Ang-2、TNF-α、IL-6含量变化.同时,观察临床指标,对比分析不同氧合指数、休克指数和碱缺失状况下的血浆Ang-2含量变化. 结果 血浆Ang-2与ISS评分呈正相关(r=0.878,P＜0.01),与炎症因子TNF-α、IL-6变化具有高度的一致性(r=0.720,r=0.758,P＜0.01);休克指数增加或氧合指数下降时,血浆Ang-2值显著升高(P＜0.01);碱缺失升高,血浆Ang-2值也随之显著升高(P＜0.01). 结论 Ang-2是创伤后早期出现内皮激活和机能失调的重要标志,与炎症介质释放和组织氧合灌注密切相关,可能与创伤后病情进展和预后密切相关.     

不同年龄组严重创伤患者的临床特点分析

 目的分析不同年龄组严重创伤患者的临床特点,以制订相应的预防、抢救及治疗措施,提高救治成功率.方法回顾性分析1999年1月～2003年1月收治的1 246例严重创伤患者,分为4组:儿童组、青年组、中年组、老年组,将各组性别比例、致伤原因、伤后死亡时间、损伤严重程度评分(ISS)和格拉斯哥昏迷计分(GCS)与预后的关系进行比较.结果各年龄组均以男性患者多见.致伤原因主要为交通伤,其次为坠落伤、钝锐器伤、跌伤等.全组患者伤后24h内的死亡率为8.8%,24 h以后的死亡率为2.0%,老年组伤后24 h内的死亡率和青年组相比有显著性差异(P＜0.01),24 h以后的死亡率和青年组相比有显著性差异(P＜0.01),和中年组相比有差异(P＜0.05).ISS对预后的影响是计分越高,患者死亡的可能性越大,而GCS则正好相反,即计分越低,死亡率越高.老年组死亡患者的ISS和GCS与其他年龄组相比,有差异或显著性差异.结论各年龄组严重创伤患者在性别比例、致伤原因、预后等方面具有不同的临床特点.ISS及GCS是判断创伤严重程度和预后较为客观的2个指标,抢救治疗以伤后24h内尤其重要,对老年患者更应引起足够重视.

Acute kidney injury in severely injured patients admitted to the Intensive Care Unit

Background:Our objective was to identify possible associations between clinical and laboratory variables and the risk of developing acute kidney injury (AKI) in severely injured patients admitted to the Intensive Care Unit (ICU) for whom creatine kinase (CK) levels were available.Methods:For this retrospective observational study,we analyzed adult trauma patients admitted to the ICU from 2011 to 2015 at Fundación Valle del Lili (FVL) University Hospital.Our primary outcome was the incidence of AKI.Multivariate regression analysis was used to assess risk factors for this outcome.Results:A total of 315 patients were included.The trauma mechanisms were blunt (n=130),penetrating (n=66) and blast (n=44) trauma.The median[interquartile range,IQR) of injury severity score (ISS) was 21 (16-39).AKI developed in 75 patients (23.8％).Multivariate regression analysis revealed that the thoracic abbreviated injury scale (AIS) value(median (IQR) in the AKI group:3 (0-4)],Acute Physiology and Chronic Health Evaluation (APACHE Ⅱ) score[median(IQR) in the AKI group:18 (10-27)],CK greater than 5000 U/L,lactic acid concentration at admission,and dobutamine administration were independently associated with AKL Conclusions:We found that age,APACHE Ⅱ score,thoracic trauma,lactic acidosis,and dobutamine administration were independently associated with AKL Trauma surgeons need to be aware of the increased odds of AKI if one of these factors is identified during the evaluation and treatment of injured patients.
