降钙素原在分辨细菌培养阳性重要致病菌中的意义 作者：张丽平 赵东来源：《中国医药科学》第 07 期 [摘要] 目的 探讨降钙素原分辨细菌培养阳性患者重要致病菌的意义。 办法 选用包头医学院第二附属医院 12 月～12 月住院患者 252 例，同时做细菌培养和 PCT 检测，分析革兰氏阳性菌、革兰氏阴性菌、真菌与 PCT 的有关性。 成果 120 培养阳性患者，其中革兰氏阳性菌32（26.7%）例、革兰氏阴性菌 69（57.5%）例、真菌 19（15.8%）例。革兰氏阴性菌 PCT 中位数水平（1.31μg/L，IQR：0.231～9.255）高于革兰氏阳性菌（0.444μg/L，IQR：0.139～2.08），P [核心词] 降钙素原；中位数；四分位数间距；革兰氏阳性菌；革兰氏阴性菌 [中图分类号] R446.1 [文献标记码] A [文章编号] 2095-0616（）07-115-04 Significance of procalcitonin in division of main pathogens of bacterial culture ZHANG Liping ZHAO Dong Clinical Laboratory，the Second Affiliated Hospital of Baotou Medical College，Baotou 014030，China [Abstract] Objective To explore the significance of procalcitonin in division of main pathogens of bacterial culture. Methods 252 hospitalized patients in the Second Affiliated Hospital of Baotou Medical College from December to December were selected.At the same time，bacterial culture and PCT detection were carried on.Correlations between gram positive bacteria and gram negative bacteria，fungi and PCT were analyzed. Results Among the 120 positive patients，there were 32 cases of gram positive bacteria 26.7%，69 caes of gram negative bacteria 57.5% and 19 cases of fungi 15.8%.Median PCT level in gram negative bacteria was 1.31μg/L，IQR：0.231-9.255，which was significantly higher than that in gram positive bacteria with 0.444μg/L，IQR：0.139-2.08，P [Key words] Procalcitonin；Media；Four digit spacing；Gram positive bacteria；Gram negative bacteria 近年来 PCT 已经成为一种用于全身性细菌感染诊疗与治疗监测的非创伤性临床实验室新指标，现在已广泛应用于临床[1-3]...
