摘　　要：目的探讨血清中降钙素原(PCT)以及C-反应蛋白(CRP)在老年性重症肺感染中病原体鉴别诊断的意义。方法整群选取该院2012年1月—2015年1月间收治的49例老年重症肺感染患者为研究对象,按其病原学分为细菌感染组27例,病毒感染组12例,真菌感染组10例。分别检测其PCT以及CRP量。结果细菌感染组血清PCT与CRP阳性率明显高于真菌感染组和病毒感染组,差异有统计学意义(P<0.05);细菌感染组PCT含量明显高于真菌感染组和病毒感染组,差异有统计学意义(P<0.05);而3组C-反应蛋白含量比较差异无统计学意义(P>0.05)。结论肺部感染PCT与CRP均升高。不同感染类型其血清PCT升高幅度不同,而CRP含量差异不明显。PTC鉴别肺部感染病原体较CRP更具优越性。Objective To study the significance of Calcitonin original and C reactive protein in the identification of the pathogen of severe pulmonary infection in the elderly. Methods 49 cases of elderly patients with the pathogen of severe pulmonary infection treated in our department from January 2012 to January 2015 were selected as the research object and divided into bacterial infection group of 27 cases, virus infection group of 12 cases and fungal infection group of 10 cases according to their etiology, PCT and CRP of the three groups were detected respectively. Results The positive rates of PCT and CRP in the bacterial infection group were significantly higher than these in the fungal infection group and virus infection group, and the difference was statistically significant （P〈0.05）;PCT content in the bacterial infection group was significantly higher than that in the fungal infection group and virus infection group, and the difference was statistically significant （P〈0.05）;C- reactive protein content of the three groups was not obviously different （P〉0.05）, and there was no statistically signifi-cance. Conclusion Pulmonary infection of PCT and CRP were elevated, ascending range of serum PCT was different in different infection types and the difference of CRP content was not obvious. PTC identification of pulmonary infection pathogen is more advantageous than CRP.
