目的掌握四川省阿坝州大骨节病患者发生、发展趋势,为探索有效防控措施提供科学依据。方法根据《阿坝州扶贫开发和综合防治大骨节病试点工作巩固提升方案》并结合《2013年阿坝州大骨节病监测实施方案》的要求,在223个病区村开展大骨节病病情和相关危险因素监测,对监测结果进行分析。结果临床检查7~12岁儿童5 785人,未查出Ⅰ度及Ⅰ度以上大骨节病病人;拍摄7~12岁儿童X线片5 785张,X线阳性片8张,全部为干骺端阳性,平均X线阳性检出率为0.14%;采集7~12岁儿童发样352份;发硒含量在0.08~0.35 mg/kg之间,均值为0.19 mg/kg;采集主食粮样113份,粮食T-2毒素检测值在0~19.8 ng/g之间,均值为3.88 ng/g。结论 2013年四川省阿坝州7~12儿童临床无新发大骨节病例,粮食T-2毒素无超常聚集,大骨节病病情目前处于相对稳定状态。
Objective To understand the occurrence and development trend of patients with Kaschin-Beck disease in Aba Prefecture, Sichuan Province, and to provide a scientific basis for exploring effective prevention and control measures. Methods According to the requirements of “Implementing Poverty Alleviation and Development and Comprehensive Prevention and Treatment of Kashin-Beck Disease in Aba Prefecture, Combining with the Implementation Plan of Kashin-Beck Disease Monitoring in 2013 in Aba Prefecture”, Kashin-Beck disease was carried out in 223 ward villages and related risks Factors monitoring, the monitoring results were analyzed.

A total of 5 785 X-ray films and 8 X-ray films were obtained from 7 to 12-year-old children, all of which were metaphyses End positive, the average positive X-ray detection rate was 0.14%; collection of children aged 7 to 12 samples 352; selenium content of 0.08 ~ 0.35 mg / kg, with an average of 0.19 mg / kg; The detection value of T-2 toxin in food ranged from 0 to 19.8 ng / g with a mean value of 3.88 ng / g. Conclusions In 2013, 7 to 12 children in Aba prefecture, Sichuan Province, had no new cases of Kaschin-Beck disease.
