目的 观察早期胰岛素强化治疗严重创伤后血清高迁移率蛋白B1（HMGB1）水平的变化,并探讨其与患者预后的关系.方法 将80例严重创伤患者[创伤严重度评分（ISS）≥16分]根据最重损伤解剖部位近似原则配对分组.强化治疗组（40例）早期即给予胰岛素强化治疗;常规治疗组（40例）根据临床经验给予常规胰岛素治疗.记录患者治疗72 h内胰岛素用量及血糖水平;于治疗后24、36、48、60、72 h检测血清HMGB1水平;记录1周内相关终点事件[包括多器官功能障碍综合征（MODS）、死亡];并分析HMGB1水平与预后的关系.结果 治疗72 h内强化治疗组胰岛素用量明显大于常规治疗组,血糖水平明显低于常规治疗组.强化治疗组治疗36 h时HMGB1水平有所下降,且36、48、60、72 h时HMGB1水平（μg/L）明显低于常规治疗组（36 h：41.3±9.5比52.7±11.5,48 h：48.6±17.6比124.1±22.9,60 h：47.7±23.3比132.9±33.4,72 h：54.3±26.3比140.6±16.5,P＜0.05或P＜0.01）.强化治疗组MODS发生率和病死率均明显低于常规治疗组（20.0%比55.0%,10.0%比30.0%,均P＜0.05）.常规治疗组内HMGB1≥132.26μg/L的22例患者均发生了MODS,＜132.26μg/L的18例患者均未发生MODS;且12例死亡患者HMGB1均≥132.26μg/L.结论 严重创伤患者发生应激性高血糖后即给予胰岛素强化治疗,可有效抑制HMGB1升高,减少MODS发生率;HMGB1可能作为重度创伤患者判断预后的指标.

英文摘要：

Objective To study the effect of intensive insulin therapy on serum high mobility group box 1（HMGB1）levels and its relationship with the prognosis in early phase of severe trauma. Methods Eighty severe trauma patients[injury severity score（ISS）≥16]were divided into groups according to injury to matched anatomical regions. Forty patients of intensive therapy group were given early intensive insulin therapy, while another 40 patients of the conventional treatment group received routine treatment based on clinical experience with insulin treatment. The insulin dose and the blood glucose levels were recorded within 72 hours after treatment. The relationship between HMGB1 levels and prognosis was analyzed by testing serum HMGB1 levels at 24, 36, 48, 60 or 72 hours after treatment, and clinical terminal events such as multiple organ dysfunction syndrome（MODS）and death rate within 1 week were recorded. Results The insulin dose of intensive therapy group was significantly greater than that of conventional treatment group following the blood glucose levels were significantly lower than those of the conventional treatment group after treatment for 72 hours. The levels of HMGB1（μg/L）lowered after intensive insulin therapy for 36 hours, and were significantly lower than those of conventional treatment group at 36, 48, 60 and 72 hours after intensive treatment（36 hours： 41.3 ± 9.5 vs. 52. 7± 11.5, 48 hours： 48. 6 ± 17. 6 vs. 124. 1 ± 22. 9,60 hours： 47.7±23. 3 vs. 132. 9±33. 4, 72 hours： 54.3±26. 3 vs. 140. 6±16.5, P〈0. 05 or P〈0. 01）.The incidence of MODS and mortality in intensive therapy group was respectively significantly lower than that of the conventional treatment group（20. 0% vs. 55.0%, 10. 0% vs. 30.0%, both P〈0. 05）. In conventional treatment group the patients with HMGB1≥132.26 μg/L（n=22）occured MODS, and those with HMGB1〈132. 26 μg/L（n= 18）did not occur MODS. The HMGB1 levels in death patients（n= 12）were ≥ 132.26 μg/L. Conclusion Early intensiv
