目的了解四川省克山病病区现状,为四川省克山病预防控制提供科学依据。方法按统一调查方案对选定的冕宁县、西昌市、大竹县等12县的调查点内3～70岁常住人口进行问卷调查,临床查体,描记12导联心电图,疑似病例摄2 m后前位X线胸片,调查当地补硒干预措施,用原子荧光法测定人群发硒和家庭主食粮食硒的含量。结果 12县(市)调查点调查8 198人,检出慢型和潜在型克山病共69例,总检出率为0.84%(69/8 198),其中慢型克山病25例,检出率0.30%(25/8 198),潜在型克山病44例,检出率0.54%(44/8 198),未发现急型和亚急型克山病例。病区居民头发硒均值0.306 7μg/g,粮食硒均值<0.01 mg/kg的样品比例50.8%。结论 2009年四川省调查点克山病检出率较低,病区居民发硒、粮硒检出较低。
Objective To understand the current status of Keshan disease in Sichuan Province and provide a scientific basis for the prevention and control of Keshan Disease in Sichuan Province. Methods According to the unified investigation plan, questionnaire survey was conducted on selected resident population from 3 to 70 years old in Mianning County, Xichang City, Dazhu County and other 12 counties. Clinical examination and 12-lead electrocardiogram were performed. After 2 m of suspected cases X-ray chest X-ray survey of local selenium interventions, the use of atomic fluorescence spectrometry determination of selenium in the population and the family staple food selenium content. Results A total of 8 198 people were surveyed in 12 counties (cities). A total of 69 cases with chronic and latent Keshan disease were detected. The overall detection rate was 0.84% (69/8 198), of which 25 cases were chronic Keshan disease, The detection rate was 0.30% (25/8 198), latent Keshan disease was 44 cases, the detection rate was 0.54% (44/8 198). No acute and subacute Keshan cases were found. Ward residents hair selenium average 0.306 7μg / g, grain selenium average <0.01 mg / kg sample ratio 50.8%. Conclusion In 2009, the detection rate of Keshan disease in Sichuan Province was lower, residents in the ward made selenium and the grain selenium was detected lower.
