感染性休克(infectious shock)是临床常见危急重症,发病率与致死率均较高。积极预测患者病情,进行休克患者分级管理有助于降低医疗风险,减少患者医疗负担~([1])。因此找到一种早期预测患者感染性休克的指标具有重要意义~([2])。炎症因子活化和氧化应激反应导致的微循环障碍是感染性休克的重要病理生理之一,血液中白细胞的含量与患者全身炎症状态密切相关,特别是中性粒细胞参与血管内皮损伤与动 Infectious shock (infectious shock) is a common clinical critically ill, morbidity and mortality are higher. Actively predict the patient’s condition, the classification of patients with shock help to reduce medical risks and reduce the medical burden on patients ~ ([1]). Therefore, to find an early prediction of septic shock in patients with indicators of great significance (2). Microcirculatory disturbance caused by activation of inflammatory cytokines and oxidative stress is one of the important pathophysiologies of septic shock. The content of leukocytes in blood is closely related to the systemic inflammatory state of patients, especially the neutrophils participate in the injury of vascular endothelial cells
