探讨血清降钙素原（PCT）和超敏C-反应蛋白（hsCRP）的检测在小儿支气管肺炎中的应用价值。

收集80例感染者样本（一般感染组和严重感染组患者各40例），另选择40例健康体检中心正常儿童为对照组。分别检测样本中PCT、hsCRP浓度、白细胞数（WBC）和Sepsis评分值，比较两个感染组患者与对照组血清PCT、hsCRP、WBC计数和Sepsis评分的差异，分别比较两个感染组患者PCT、hsCRP、WBC计数和Sepsis评分治疗前后的差异。

治疗前，一般感染组和严重感染组患者分别与对照组相比，PCT、hsCRP、WBC计数和Sepsis评分差异均具有统计学意义（P均< 0.05）。治疗后，感染组患者的各项指标与治疗前差异均具有统计学意义（P均< 0.05）。治疗后，严重感染组与一般感染组患者各指标相比，PCT、hsCRP和WBC计数水平差异具有统计学意义（P均< 0.05）；但两组Sepsis评分差异无统计学意义（t = 0.821、P = 0.241）。

血清PCT水平、hsCRP水平与小儿支气管肺炎严重程度呈正相关，PCT与hsCRP检测对小儿支气管肺炎的诊断与治疗具有重要的指导意义。

To investigate the application value of serum procalcitonin and high sensitivity C-reactive protein (hsCRP) in children with bronchial pneumonia.

Total of 80 specimens from 80 cases with infection (40 cases with general infection and 40 cases with severe infection) were collected, while 40 cases from physical examination center were collected as control group. The levels of PCT, hsCRP and WBC counts were detected, and the score of sepsis were calculated, respectively. The levels of PCT, hsCRP, WBC and sepsis score were compared among two infection groups and the control group, respetively, and the levels of PCT, hsCRP, WBC and sepsis score of two infection groups were compared before and after treatment, respectively.

Before treatment, the levels of PCT, hsCRP, WBC and sepsis score of patients in infection group were significantly different compared with those of control group (all P < 0.05). After treatment, all indexes of patients in infection group had significant differences compared with the indexes before treatment (all P < 0.05). The levels of PCT, hsCRP, WBC counts of patients in severe infection had significant differences compared with those in general infection group after treatment (all P < 0.05), but sepsis score had no significant differences between the two groups (t = 0.821, P = 0.241).

Serum PCT and hsCRP were positively correlated with infantile bronchial pneumonia severity, which could guide the treatment and curative effect of bronchopneumonia.
