【摘要】 目的探讨降钙素原(PCT)、超敏C反应蛋白(hs-CRP)及WBC检测在儿童支气管肺炎中的应用。方法选取细菌感染支气管肺炎患儿89例、病毒感染支气管肺炎患儿92例、支原体感染支气管肺炎患儿90例和健康体检儿童100例,检测其PCT、hs-CRP和WBC水平并行统计学分析。结果细菌感染时PCT与hs-CRP、WBC呈正相关(r=0.807、0.764,P<0.05),且三者联合检测阳性率明显高于病毒感染和支原体感染(P<0.05)。结论 PCT、hs-CRP、WBC是细菌感染的敏感指标,联合检测对诊断细菌感染儿童支气管肺炎、动态监测其病情发展及预后判断具有重要的临床参考价值。更多还原

【Abstract】 Objective Discussing the correlation between joint detection of procalcitonin(PCT),hypersensitive c-reactive protein(hs-CRP),WBC and bronchopneumonia in children.Methods Choosing 89 bacterial infection bronchopneumonia children,92 virus infection bronchopneumonia children,90 mycoplasma infection bronchopneumonia children and 100 normal children,detecting their PCT,hs-CRP,WBC and statistical analysis of the level of parallelism.Results There is a positive correlation between bacterial infection group′s PCT and hs-CRP,WBC(r=0.807,0.764,P<0.05).The joint detection of PCT,hs-CRP,WBC positive rate in bacterial infection group is significantly higher than the rest group(P<0.05).Conclusion PCT,hs-CRP and WBC is a sensitive indicator of bacterial infection.There is important clinical reference value in joint detection to the diagnosis of bacterial infection bronchopneumonia in children,in dynamic monitoring the disease progression,and in prognosis judgement.更多还原
