C-反应蛋白与血沉在肺部感染诊断中比较研究

目的探讨c-反应蛋白联合血沉在肺部感染诊断中的意义。方法选择肺部感染患者150例为感染组；以同期无感染的患者42例作为非感染组；以同期健康体检者30例为对照组。患者入院时检测血常规，测定c-反应蛋白（CRP）、血沉（ESR）。结果感染组c-反应蛋白、ESR、白细胞计数（WBC）和中性粒细胞百分比（N）均高于对照组，差异有统计学意义（P〈0．05）；感染组白细胞计数（WBC）、中性粒细胞百分比（N）和c-反应蛋白均高于非感染组，差异有统计学意义（P〈0．05）；非感染组c-反应蛋白、ESR高于对照组，差异有统计学意义（P〈0．05）。结论c-反应蛋白联合血沉可以作为肺部感染诊断的参考指标。

Comparative study between C-reactive protein and erythrocyte sedimentation rate in the prognosis of pulmonary infection

Objective To investigate the clinical significance of CRP and ESR in the prognosis of pulmonary infection. Methods 222 people were divided into three groups based on their conditions： the infection group （n = 152）, the non-infection group （n =42） , and the healthy group （ n = 30）. All of them were given the routine blood test to detect the levels of their CRP and ESR. Results The levels of PCR, ESR, white blood cell （WBC） and neutrophil count percentage （N） were significantly higher in the infection group than those in the control group and in the non-infection group （ P 〈 0. 05 ）. The levels of CRP and ESR in the non-infection group were significantly higher than those in the control group （P 〈 0. 05 ）. Conclusion The serum levels of CRP and ESR can be the useful indexes for clinical monitoring of pulmonary infection.
