摘要：目的：探讨不同病原体肠炎患儿血PCT、CRP的变化及其临床意义。方法：对确诊的32例细菌性肠炎患儿、30例病毒性肠炎患儿的血PCT、CRP进行检测。结果：以PCT>0.5μg/L、CRP>10mg/L为阳性阈值，细菌组的PCT、CRP阳性率分别为87.5%、84.4%，病毒组的PCT、CRP阳性率分别为20.0%、40.0%，细菌组较病毒组高(P<0.01)。CRP诊断细菌性肠炎敏感度、特异度、准确度、阳性预测值及阴性预测值较PCT小。结论：血PCT、CRP检测对鉴别小儿肠炎的病原体有重要临床意义，而PCT检测较CRP诊断细菌性肠炎价值更高。

    Abstract：Objective: Discusses different pathogen child enteritis blood PCT, CRP changes and its clinical significance. Method: To 32 examples child diagnosed bacteria enteritis , 30 examples child virulent enteritis blood PCT, CRP carries on the examination. Result：Take PCT>0.5 mu g/L, CRP>10mg/L as the masculine threshold value, bacterium group's PCT, the CRP masculine gender rate separately is 87.5%, 84.4%. viral group's PCT, the CRP masculine gender rate separately is 20.0%, 40.0%, the bacterium group compared with the viral group is higher (P<0.01). The CRP diagnosis bacterium enteritis sensitivity, the peculiarity, the accuracy, the masculine forecast value and negative forecast value PCT is smaller. Conclusion: Blood PCT, the CRP examination to distinguishes the enteritis the pathogen i children has the vital clinical significance, but it's more valuable to detect PCT than CRP in diagnosing bacterium enteritis in children. ......
