我国5省区非大骨节病病区村儿童掌指骨干骺端改变率调查

摘要

目的 研究非大骨节病病区村7～12岁儿童干骺端的改变率,为病区村判定消除大骨节病提供依据.方法 在吉林、辽宁、陕西、山西和内蒙古5个大骨节病病区省份随机调查36个非大骨节病病区村.用全数字化多功能X线摄影系统(DR)拍摄每个调查村全部7～12岁儿童右手X线片,并按照《大骨节病诊断》标准(WS/T 207-2010)诊断.结果 在调查的36个村中,只有13个村的儿童右手X线干骺端发生改变,且无骨端改变病例,以村为单位X线干骺端改变率均＜3％.结论 建议判定病区村消除大骨节病的标准为7～12岁儿童干骺端改变率＜3％.%Objective 36 non-Kaschin-Beck disease villages in five provinces including Jilin,Liaoning,Shaanxi,Shanxi and Inner Mongolia in the severe endemic areas of Kaschin-Beck disease (KBD) were selected.The aim of this project was to provide the basis showing these KBD villages had already eliminated the KBD.Methods Fully digital versatile X-ray radiography systems (DR) was used to shoot children's right hand X-ray,in accordance with the "Kashin-Beck Disease Diagnosis Standard" (WS/T 207-2010) for diagnosis.Results Results indicated that children showing metaphyseal changes only appeared in 13 of the 36 villages,where the rate of change on metaphyseal was less than or equal to three percent.Conclusion When KBD had been eliminated in a village,the rate of change on aged 7 to 12 children' s metaphyseal would have been less than three percent.
