目的 通过对青海省兴海县大骨节病新发病区调查,了解大骨节病病区分布范围,流行强度和流行趋势,为大骨节病防治研究提供依据.方法 按全国大骨节病监测方案要求,对兴海县唐乃亥乡,子科滩镇,桑当乡及曲什安乡共6个村的7～13岁儿童进行流行病学调查,临床检查及X线拍片,并采集发样,粮样,土样,水样.用2,3-二氨基萘荧光法进行含硒量测定.结果 在4个调查点的6个村共临床检查7～13岁少年儿童373人,检出大骨节病45例,检出率为12.06%.X线拍片347人,X线阳性75例,阳性检出率为21.61%.子科滩镇泉曲村含硒量最低,发硒为(77.70±42.04)μg/kg,粮硒为(7.44±6.93)μg/kg,曲什安乡才乃亥村含硒量最高,发硒为(103.88±58.57)μg/kg,粮硒为(29.58±24.11)μg/kg.结论 兴海县4个调查点为大骨节病新病区.调查点大骨节病病情严重,致病因子活跃.

Investigation on Kashin-Beck disease in Xinghai County,Qinghai Province in 2006

Objective By investigating newly diagnosed Kashin-beck disease,to understand distribution range,epidemic intensity and prevalence trend of Kashin-Beck disease(KBD)in Xinghai County.Method According to monitoring method on national KBD,we carried on epidemical investigation,clinical examination and X-ray photograph on school children aged 7-13 years in 6 villages from 4 towns in Xinghai County,and hair,grain,water and soil were sampled to detect selenium content using naphthalene fluorescence.Resuit Three hundred and seventy.three school children aged 7-13 years underwent the clinical examination,the prevalence rate was 12.06%(45/373);347 school children were went on X-ray,the detection rate of X-ray was 21.61%(75/347).The selenium content was the lowest in Quanqu Village,Ziketan Town,which were(77.70±42.04),(7.44±6.93)μg/kg respectively;the selenium content Was highest in Cainaihai Village,Qushian Town,which were(103.88±58.57),(29.58±24.11)μg/kg respectively;level of in internal and external environment in 4 KBD region were all low.Conclusion These four region are new KBD region.The prevalence state of KBD is serious,pathogenetic factor of Kashin-Beck disease is very active.
