目的:探讨不同病情程度脓毒症患者血清Toll样受体4(toll like receptor 4,TLR4)、脂联素(adiponectin,APN)水平变化的临床意义。方法:选取2018年2月~2020年9月我院脓毒症患者96例作为观察组,其中脓毒症41例,严重脓毒症29例,脓毒性休克26...目的:探讨不同病情程度脓毒症患者血清Toll样受体4(toll like receptor 4,TLR4)、脂联素(adiponectin,APN)水平变化的临床意义。方法:选取2018年2月~2020年9月我院脓毒症患者96例作为观察组,其中脓毒症41例,严重脓毒症29例,脓毒性休克26例,同期肺部感染者71例作为对照Ⅰ组,健康体检者71例作为对照Ⅱ组。检测血清TLR4、APN水平,对比三组血清TLR4、APN水平及观察组脓毒症、严重脓毒症、脓毒性休克不同病情程度患者的一般资料、血清TLR4、APN水平,分析脓毒症病情程度与血清TLR4、APN水平关系及临床价值。结果:随病情加重,血清TLR4水平呈升高趋势,血清APN水平呈降低趋势,差异有统计学意义(P<0.05);不同病情程度患者体温、血清降钙素原水平、血清TLR4、APN水平对比,差异有统计学意义(P<0.05);经Spearman秩相关系数分析,脓毒症病情程度与血清TLR4水平呈正相关,与血清APN水平呈负相关(P<0.05);采用多元线性回归模型控制体温、血清降钙素原水平等混杂因素后,血清TLR4、APN水平仍与脓毒症病情程度有关(P<0.05)。结论:脓毒症患者血清TLR4、APN水平变化与病情程度呈独立显著相关,检测其水平变化有助于及时了解病情,为临床制定治疗方案提供参考。展开更多
