探讨降钙素原在部分细胞内与细胞外细菌感染中的区别
探讨降钙素原在部分细胞内与细胞外细菌感染中的区别【摘要】目的 探讨降钙素原（PCT)在细胞内细菌及细胞外细菌感染者中的区别。方法 回顾性统计分析200例细胞内细菌感染者及181例细胞外细菌感染者的PCT的检出率及其血清浓度，了解PCT在细胞内细菌及细胞外细菌感染者中的检出情况。结果200份细胞内细菌感染者，PCT阳性55份,检出率27.5%。181例细胞外细菌感染者，PCT阳性156份，检出率86.18%，经χ2检验分析，p=0.00，差异具有统计学意义。55例细胞内细菌感染者检测到PCT的值为（0.25±0.30）ng/ml，156例细胞外细菌感染者检测到PCT的值为（4.16±7.31）ng/ml，经t’检验分析，p＜0.05，差异具有统计学意义。 结论细胞内细菌感染者及细胞外细菌感染者，PCT阳性率及血清含量方面均具有明显差异。

Difference of the diagnosis value of serum procalcitonin (PCT) in patients with intracellular and extracellular infections
【Abstract】 Objective To determine the diagnosis value ofserum procalcitonin (PCT) in patients with intracellular infections and extracellular infections. Methods Serum procalcitonins (PCT) oftwo hundreds patients with intracellular infections and one hundred and eighty one patients with extracellular infections were analyse-d retrospectively. Investigated positive incidence of PCT in patientswithintracellularandextracellularbacteriainfection. Results The positive incidence of PCT were 27.5% and 86.18% in two hundreds patients with intracellular infections and one hundred and eighty one patients with extracellular infections respectively. The positive incidence have statistical difference by chi-square test(p=0.00). PCT serum levels of55 PCT positive patients with intracellular infections and 156 PCT positive patients with extracellular infections were (0.25±0.30) ng/ml and (4.16±7.31) ng/ml respectively. Serum levels of PCT have statistical difference by t’-test(p＜0.05). Conclusion Positive incidence and levels of PCT were significantly different in intracellular and extracellular bacterial infection.
Procalcitonin;bacillosis;intracellular;extracellular 我们自己的研究总结，希望对临床有一定的指导意义。 老师，能否把全文贴出来让大家拜读。 不懂什么叫细胞内细菌，细胞外细菌。 细胞内细菌感染检出值低于细胞外检出值，但是降钙素原检测是血清检测，不都是细胞外检测吗？ 看的有些模糊，查资料后再进一步掌握。 能否把全文贴出来。 降钙素原检测是血清检测，不明白？请指教，详细资料{:1_2:} 谢谢老师们的探讨，我也是一头雾水。 降钙素原检测是我们是血清检测 谢谢老师的资料分享，希望看到更详细的内容。 细胞外（内）细菌感染？ 谢谢老师的资料分享！何谓细胞外（内）细菌感染？请老师赐教，谢谢！
