目的　监测 2 0 0 0年全国大骨节病病情。方法　在病区省、自治区各选 1～ 2个最重病区点 ,每个点拍照 10 0名 7～ 12岁儿童右手 X光片 ,上报 ,集体读片确认患病水平。结果　东部 6省 :黑龙江、吉林、河北、河南、山西、山东 X线检出率低于 3% ,达到了控制水平。西部 6省、区 (西藏、青海、甘肃、陕西、四川、内蒙古 ) ,检出率仍然很高 ,14点中 8个超过 2 0 % ,最高的达到 46 .5 % (青海 ) ,表明病情仍然活跃而严重。结论　今后防治重点应放在西部 ,结合西部大开发计划中的“种树种草、以粮代赈”政策的落实 ,争取在不太久的时间内控制大骨节病 Objective To monitor the prevalence of Kaschin-Beck disease in 2000. Methods One to two cases of the most severe disease in each of the provinces and autonomous regions in the ward were photographed. Right-handed x-rays of 10 0 to 7 years old children were photographed at each point, and their prevalence was reported and collectively read. Results The six eastern provinces: Heilongjiang, Jilin, Hebei, Henan, Shanxi, Shandong X-ray detection rate of less than 3%, reaching the control level. The detection rate was still high in 6 provinces and autonomous regions in western China (Tibet, Qinghai, Gansu, Shaanxi, Sichuan and Inner Mongolia), with 8 out of 14 over 20% and the highest reaching 46.5% (Qinghai) Active and serious. Conclusion The focus of prevention and treatment should be put on the west in the future. In combination with the implementation of the policy of “planting trees and grazing in food for relief” in the plan for the development of western China, we should strive to control Kashin-Beck disease in a relatively short period of time
