背景目前多数研究者们认为在胃肠功能受损时,血清HSP70具有较高的敏感性,为早期肠缺血的敏感指标,但血清中热休克蛋白70(HSP70)在创伤性颅脑外伤(traumatic head injury,TBI)患者的胃肠功能评估中的研究较少,值得进一步研究.目的探究TB...背景目前多数研究者们认为在胃肠功能受损时,血清HSP70具有较高的敏感性,为早期肠缺血的敏感指标,但血清中热休克蛋白70(HSP70)在创伤性颅脑外伤(traumatic head injury,TBI)患者的胃肠功能评估中的研究较少,值得进一步研究.目的探究TBI合并急性胃肠功能损伤(acute gastrointestinal impairment,AGI)患者HSP70水平的变化及意义.方法选取2019-03/2020-10期间天津医科大学总医院重症监护病房就诊并住院的TBI合并AGI患者133例作为研究对象,按照改良Glasgow昏迷评分法并结合创伤性颅脑损伤临床分型标准,将研究对象分为轻型63例,中型32例,重型38例;按照AGI分级标准,将研究对象分为AGIⅠ级68例,AGIⅡ级37例,AGIⅢ级17例,AGIⅣ级11例.另选取50例于我院进行常规体检的无颅脑外伤病史、各系统基础疾病者作为对照组.比较不同脑外伤程度及不同AGI分级患者与对照组血清中HSP70水平,并分析TBI合并AGI患者血清HSP70水平与脑损伤程度、AGI分级的相关性,同时分析其单独诊断TBI合并AGI的诊断效能.结果入院当天,随着脑损伤程度的加重,血清HSP70水平也逐渐升高,且各型HSP70水平均显著高于对照组患者,而随着AGI分级的提高,血清HSP70水平也逐渐升高,且各分级HSP70水平均显著高于对照组患者,差异均有统计学意义(P<0.05);入院第3天,各型血清HSP70水平较入院当天数值明显降低,但数值仍高于对照组患者,而各分级血清HSP70水平较入院当天数值明显降低,但数值仍高于对照组患者,差异均有统计学意义(P<0.05);Pearson检验发现,TBI合并AGI患者血清HSP70水平与脑损伤程度、AGI分级均呈显著正相关(r_(s)=0.802、0.836,P<0.01);ROC曲线显示,血清HSP70诊断TBI合并AGI的试验准确性较高,AUC为0.803,95%CI为0.720-0.872.当最佳截断值为258.50 ng/L时,敏感度为80.94%,特异度为87.93%,约登指数为0.501.结论HSP70在TBI合并AGI患者血清中的表达显著上调,可能与疾病发展进程有关,对TBI合并AGI有较高的诊断价值.展开更多
