Acute mesenteric ischemia (AMI) is a potentially fatal disease. Difficulties in diagnosis make it essential to find early biomarkers.
This study investigated the diagnostic value of procalcitonin (PCT) levels in AMI.
Animal experimentation.
Rats were divided into six groups of six animals each. In the experimental group, an experimental ischemia model was established by clamping the superior mesenteric artery from the aortic outflow tract. Blood and tissue specimens were collected from rats in the experimental mesenteric ischemia model at 30 min and 2 and 6 h, and these were compared with specimens from the respective control groups. PCT levels were compared at 30 min and 2 and 6 h.
PCT levels were 185.3 pg/mL in the control group and 219.3 pg/mL in the study group, 199.6 pg/mL in the control group and 243.9 pg/mL in the study group, and 201.9 pg/mL in the control group and 286.9 pg/mL in the study group, respectively, at 30 minute, 2 and 6 hours. Significant differences were determined between 6-h control group and ischemia group PCT levels (p=0.005).
The absence of a significant increase in PCT levels in the early period, while a significant difference was detected in the later period (6 h), shows that PCT levels rise late in mesenteric ischemia and can be a marker in the late period.
急性肠系膜缺血(AMI)是一种潜在致命的疾病。由于诊断困难,因此寻找早期生物标志物至关重要。
本研究旨在探讨降钙素原(PCT)水平在 AMI 中的诊断价值。
动物实验。
将大鼠分为六组,每组六只。在实验组中,通过从主动脉流出道夹闭肠系膜上动脉来建立实验性缺血模型。在实验性肠系膜缺血模型中,于 30 分钟和 2 小时及 6 小时从大鼠收集血液和组织标本,并与各自的对照组进行比较。在 30 分钟、2 小时和 6 小时时比较 PCT 水平。
对照组 PCT 水平为 185.3pg/ml,研究组为 219.3pg/ml;对照组 PCT 水平为 199.6pg/ml,研究组为 243.9pg/ml;对照组 PCT 水平为 201.9pg/ml,研究组为 286.9pg/ml。在 30 分钟、2 小时和 6 小时时,6 小时对照组和缺血组的 PCT 水平存在显著差异(p=0.005)。
早期 PCT 水平没有明显升高,而后期(6 小时)检测到明显差异,表明 PCT 水平在肠系膜缺血中升高较晚,可作为晚期标志物。
