摘　　要：目的探讨降钙素原(PCT)对老年细菌性肺炎患者诊断价值的研究。方法选择230例老年细菌性肺炎患者分成肺炎感染组(A组)、缓解组(B组)和选择234例健康对照组(N组)作为研究对象,测定血清PCT(procalcitionin,PCT)、血清C-反应蛋白(CRP)和周围血白细胞计数,并对测得结果作比较。结果老年肺炎患者感染时血清PCT、CRP、周围血白细胞计数明显升高,经过治疗后其患者病情缓解时上述三项参数值明显降低。结论测定血清PCT比测定血清CRP、周围血白细胞对诊断老年肺炎的价值高,而上述三项联合检测对诊断老年肺炎更具有临床意义。Objective To investigate the clinical diagnosis value of serum procalcitonin （PCT） in elderly patients with bacterial pneumonia. Methods 230 elderly patients with bacterial pneumonia were divided into the pneumonia infection group （group A） and the anesis group （ group B） , and another 234 healthy people were taken as the control group （ group N）. Their serum PCT, CRP and periph- eral white blood cell count were measured and compared among the three groups. Results The levels of PCT and CRP and the count of peripheral white blood cell were significantly higher in the group A than the rest two groups. After the treatment, they all decreased obviously in the group A and B. Conclusion The detection of PCT is more meaningful than that of serum CRP and peripheral white blood cell. The combined detection of the three indexes has the most valuable significance for the diagnosis of elderly patients with bacterial pneumonia.
