1小时手枪射击后警校大学生免疫功能的改变

Changes in the immune function of police officer college students at one hour after shooting

目的:观察射击运动对警官学校大学生免疫功能的影响。方法:于2005-10在辽宁警官高等专科学校二年级5个教学班的1次教学射击课中,抽签随机选取其中的一个班的男性学生20名为实验对象。年龄(19±3)岁,身高(174.1±8.9)cm,体质量(72.4±4.2)kg。实验时间为一堂手枪射击课。准备活动后先进行空靶瞄射20min,然后进行1h120发实弹射击,要求2发/min,统一按口令进行击发。在上课前和射击运动结束后分别进行免疫指标白细胞介素2、可溶性白细胞介素2受体、肿瘤坏死因子、T淋巴细胞亚群CD3+、CD4+、CD8+和CD4+与CD8+比值的测定。结果:学生20名的测试数据均进入结果分析。与射击运动前相比,1h的射击运动后,所测20名大学生的补体C3、白细胞介素2升高[(1.12±0.14),(1.23±0.17)mg/L;(57.83±24.3),(75.95±29.7)μg/L,P<0.05),可溶性白细胞介素2受体下降[(508.36±32.4),(481.64±43.6)μg/L,P<0.05),淋巴细胞亚群辅助性T细胞CD4+升高[(35.88±5.52)%,(39.83±4.30)%,P<0.05),CD4+/CD8+比值无明显变化。结论:射击运动有助于提高警官学校大学生机体的免疫功能。

AIM： To observe the effect of shooting on the immune function of students of Police Officer Junior College. METHODS： Twenty male sophomores were randomly selected from 5 classes of Liaoning Police Officer Junior College in a shooting class in October 2005, whose age was （19±3） years and the body height was （174.1±8.9） cm and the body mass was （72.4±4.2） kg. Time of the shooting class was set as the experimental time. 20-minute aiming at air target was conducted after warming up, and students conducted 120 times of live shell shooting by following unified orders. Indexes such as interleukin-2 （IL-2）, soluble IL-2 receptor （slL-2R）, tumor necrosis factor-α （TNF-α）, CD3^-, CD4^-, CD8^-, and CD4^-/CD8^- were measured before the class as well as before and after shooting respectively. RESULTS： Data of 20 students were involved in the analysis of results. One hour after the shooting, the levels of C3 and IL-2 in 20 students obviously increased than those before shooting [（1.12±0.14）, （1.23±0.17） mg/L; （57.83±24.3）, （75.95±29.7）μg/L,P 〈 0.05）, while slL-2R decreased [（508.36±32.4）, （481.64±43.6） μg/L ,P 〈 0.05）, and T cell CD4- increased [（35.88±5.52）%, （39.83±4.30）%,P 〈 0.05）, and no change was found in CD4^-/CD8^-. CONCLUSION： Shooting can improve the immune function of police officer college students.
