摘　　要： 目的分析某小学五年级小学生在有、无火灾情景模拟认知训练的条件下进行实践演练时对外周血的影响。方法 2016年6月抽取某小学五年级90例小学生按性别和年龄将其平均分成三组,对照组、实验组(未训练组、训练组)。分别对参加实践演练的实验组及对照组的小学生用EDTA-K2抗凝管抽静脉血2 ml在迈瑞BC-5390全自动血球仪上进行白细胞计数、嗜中性粒细胞百分率、淋巴细胞百分率、单核细胞百分率、红细胞计数、血小板计数。结果 (1)未训练组的白细胞计数、嗜中性粒细胞百分率、血小板计数、红细胞计数均明显高于对照组,差异有统计学意义(P<0.05),淋巴细胞百分率和单核细胞百分率明显低于对照组,差异有统计学意义(P<0.01)。(2)未训练组的白细胞计数、嗜中性粒细胞百分率、血小板计数、红细胞计数均高于训练组,差异有统计学意义(P<0.05),淋巴细胞百分率和单核细胞百分率低于训练组,差异有统计学意义(P<0.05)。(3)嗜中性粒细胞百分率与淋巴细胞百分率成负相关(r=-0.980,P<0.01)。(4)训练组的白细胞计数、嗜中性粒细胞百分率、淋巴细胞百分率、单核细胞百分率、红细胞计数、血小板计数与对照组差异无统计学意义(P>0.05)。结论小学生在火灾情景模拟认知训练后进行实践演练对维持外周血各项指标的稳定具有明显作用。 Objective To analyze the influence of practical exercise with or without fire scene simulation and cognitive training on the peripheral blood of primary school students of grade five.Methods Altogether 90 primary school students of grade five in June 2016 were selected from a primary school and divided into three groups according to their gender and age：control group and experiment group（untrained group and training group）.venous blood（2 ml） was collected by using EDTA-K2 anticoagulant tube from each primary school student of control group and experiment group who participated in the practical exercise and was analyzed by using mindray BC-5390 automatic blood cell analyzer to acquire the white blood cell（WBC） count,neutrophil percentage,lymphocyte percentage,monocytes percentage,red blood cell（RBC） count and platelet count.Results（1）WBC count,neutrophil percentage,RBC count and platelet count of untrained group were significantly higher than those of control group with statistically significant difference（P〈0.05）,while the lymphocyte percentage and monocytes percentage of untrained group were significantly lower than those of control group with statistically significant difference（P〈0.01）.（2）WBC count,neutrophil percentage,RBC count and platelet count of untrained group were higher than those of training group with statistically significant difference（P〈0.05）,while the lymphocyte percentage and monocytes percentage of untrained group were significantly lower than those of training group with statistically significant difference（P〈0.05）.（3）The neutrophil percentage was negatively correlated with the lymphocyte percentage（r=-0.980,P〈0.01）.（4）WBC count,neutrophil percentage,lymphocyte percentage,monocytes percentage,RBC count and platelet count of training group had no statistically significant difference in contrast with control group（P 0.05）.Conclusion Practical exercise after fire scene simulation and cognitive training plays an important role in
