低剂量电离辐射对放射工作人员肝功能的影响

摘要

目的 探讨低剂量电离辐射对工作人员肝功能的影响.方法 检索相关文献,根据预先设定的纳入排除标准筛选符合要求的文献,以放射组和对照组肝功能异常数及各组总人数为基本数据,将OR作为效应值,通过异质性检验选用合适模型进行分析.结果 合并OR值为1.59,95%CI为1.25~2.02(P<0.05).结论 长期暴露在低剂量电离辐射环境下会增加放射工作人员肝功能异常的检出率.%Objective To assessment the effect of low dose ionizing radiation on liver function .Methods According to predefined inclusion , exclusion criteria , the relevant literatures were reviewed and qualified literatures were evalu -ated.Based on total number of liver function examination , number of abnormal liver function in radiation group and control group , the OR as the effect size , then choose an appropriate model by the heterogeneity test for the analysis . Results The combined OR is 1.59, 95%CI 1.25-2.02.Conclusions Long term exposure to low dose-ionizing radi-ation has significant outcome shown by higher rate of liver function abnormality .
