| 目的：研究血清降钙素原（PCT）联合痰培养检测在呼吸道感染疾病中的应用价值。方法：选择2012 年1 月至2014 年12 月
在我院接受治疗的呼吸道感染患者100 例进行研究。分析痰培养菌群的分布情况以及PCT 的检测结果，对比痰培养细菌感染者
及真菌感染者的菌种分类及PCT 检测结果。结果：检出病原菌的患者PCT 水平均分别显著高于正常菌群及未见细菌生长的患
者，差异均有统计学意义（均P＜0.05）。细菌感染PCT 阳性比例与真菌感染相比，差异无统计学意义（P>0.05）。细菌感染中，革兰
氏阳性菌的PCT 水平（0.74± 0.33 滋g/L）与革兰氏阴性菌（0.72± 0.24 滋g/L）对比，差异无统计学意义（P＞ 0.05）。真菌感染中，白假
丝酵母菌及烟曲霉菌的PCT 阳性比例最高，分别为60.00%及80.00%。结论：血清PCT 与痰培养检测应用于评价有呼吸道感染的
患者病情，具有一定的反馈意义，但无法确定患者的呼吸道感染究竟是细菌感染亦或是真菌感染。 |

| Objective:To study the application value of serumprocalcitonin (PCT) combined with sputum culture in the detection
of respiratory tract infection.Methods:A total of 100 patients with respiratory tract infection, who were treated in Panjin Center Hospital
from January 2012 to December 2014, were chosen as research subjects. The flora distribution of sputum culture and the corresponding
PCT levels were analyzed. The bacterial species distribution of bacterial infection and fungal infection of sputum culture and the
corresponding PCT levels were compared.Results:The PCT levels of patients with detected pathogenic bacteria were significantly higher
than those of patients with normal flora and no bacterial growth, the differences were statistically significant (P<0.05). PCT positive rate
of patients with bacterial infection had no significant difference compared with the patients with fungal infection (P>0.05). In bacterial
infection, there was no statistically significant difference between the ratio of PCT level of the positive gram bacteria (0.74± 0.33 滋g/L)
to PCT level of the negative gram bacteria(0.72± 0.24 滋g/L) (P>0.05). The PCT positive rates of (60%) and
(80%) were the highest in fungal infection.Conclusion:Applicatin of detection of serumPCT plus sputumculture to the evaluation
of patients with respiratory tract infection has a certain feedback value, but it can not judge whether it is bacterial infection or fungal
infection. |
