摘　　要：目的通过开展2014年南京"5.7"192Ir放射源事故患者受照后持续医学随访,探讨放射损伤的中远期效应,为电离辐射损伤的效应评估提供科学依据。方法通过面访调查,询问受照患者康复治疗后至医学随访期间的新发疾病病史,进行体格和实验室检查,依据相关标准,系统评价其造血系统、免疫系统、内分泌系统、眼科、循环系统、消化系统、泌尿系统以及骨密度等生理生化指标。结果患者无新发疾病,造血系统、免疫系统、内分泌系统各项指标趋于正常;循环系统、消化系统及泌尿系统出现退行性改变;眼科检查出现视力持续下降;骨密度检查提示骨量低下。结论患者各项生理生化指标逐步恢复正常,未出现明显的放射性损伤症状,后续的医学随访观察仍需持续开展.Objective To explore the long-term effects of radiation injury and to provide scientific basis for the evaluation of the effects of ionizing radiation injury by carrying out medical follow-up of patients involved in the"5.7"radiative source accident in Nanjing in 2014.Methods Through interviewing and investigating,we inquired about the new disease history of the exposed patients from rehabilitation treatment to medical follow-up peroid.Physical and laboratory examinations were carried out.According to relevant standards,physiological and biochemical indexes such as hematopoietic system,immune system,endocrine system,ophthalmology,circulatory system,digestive system,urinary system and bone mineral density were systematically evaluated,with the long-term effects being evaluated.Results The patient′s vital signs were good without new diseases.The indexes of hematopoietic system,immune system and endocrine system tended to be normal,the circulatory system,digestive system and urinary system showed degenerative changes,the ophthalmic examination showed visual acuity continue to decline,and bone mineral density examination indicated low bone mass.Conclusions Physiological and biochemical indicators of the patients gradually returned to normal without obvious symptoms of radiation damage.Further medical follow-up observation still needs to continue.
