【摘要】 目的 探讨低剂量电离辐射对放射线暴露医务人员肝肾功能的影响。方法 选取2021年1～4月在我院进行职业健康体检的医务人员为研究对象，根据职业将其分为放射组（放射医务人员67例）和对照组（同时期非放射医务人员48例）。分析性别和年龄对两组人员肝肾功能的影响，以及放射组内不同职业和工龄等对医务人员肝肾功能的影响。采用SPSS 20.0软件进行统计分析。结果 两组间不同年龄、不同性别肝肾功能水平差异均无统计学意义（P>0.05）；放射组内男性医务人员的γ-GT、ALT、AST、BUN和Cr水平均显著高于女性；40～49岁和≥50岁年龄段的BUN水平显著高于30岁以下年龄段；γ-GT和BUN水平随着放射线暴露时间增加而升高；介入科医师/护士的ALT、AST和Cr水平均显著高于放射科医师/护士，放射科技师的ALT和AST水平显著高于放射科医师/护士。结论 长期接触低剂量电离辐射未对我院放射线暴露医务人员肝肾功能产生显著影响；从事介入工作、男性、工龄长和年龄大等放射线暴露医务人员的肝肾功能受电离辐射影响较大，应加强对相关人员的辐射防护培训和健康监测。更多还原

【Abstract】 Objective To explore the effect of long-term low-dose ionizing radiation on liver and kidney function of radiologic staff in hospital. Methods The medical staff who took an occupational health examination in our hospital from Jan to Apr 2021 were selected as the research objects, and divided into the radiation group(67radiologic staffs) and the control group(48 non-radiologic staff) according to the occupation. Biochemical indexes were collected and analyzed. Results There was no statistically significant difference between the two groups on liver and kidney function in different age and gender. In the radiation group, the level of γ-glutamyl transpeptidase(γ-GT),alanine aminotransferase(ALT), aspartate aminotransferase(AST), blood urea nitrogen(BUN) and creatinine(Cr) in male were obviously higher than those in female; the level of BUN in over 40 years old were higher than those in under 30 years old; the differences were statistically significant(P<0.05). The levels of γ-GT and BUN increased over radiation exposure time. The radiation group was divided into three groups according to the occupation, the level of ALT, AST and Cr in the interventional radiation group were higher than those in radiologists or radiology nurse; the ALT and AST levels of radiologic technologists were higher than those in radiologists or radiology nurses.Conclusion Long-term low-dose ionizing radiation didn’t significantly affect the liver and kidney function of the radiologic staff in our hospital. Apparent effect of ionizing radiation were observed in staff who were engaged in interventional medicine, male, older or with long working life. The measure to protect against radiation should be trained for the staff and their health should be monitored.更多还原
