目的 观察陕西省黄陵县克山病 8年来病情及相关因素的变化。方法 选择黄陵县的 6个重病村设立监测点 ,该区居民列为监测对象。 1995年至 2 0 0 2年连续 8年对该监测点克山病的发病情况监测及 3～15岁儿童内环境硒水平进行监测。结果 ①潜、慢型克山病的检出率 1995、1997、1999、2 0 0 0和 2 0 0 2年依次为 4 .3%、3.6 %、7.5 %、8.0 %和 8.5 % ;②潜在型克山病的新发生率 1995、1997、1999、2 0 0 0和 2 0 0 2年依次为 5 5 .6 /万、5 3.5 /万、19.5 /万、0 /万和 2 5 /万 ;③全县 8年慢型克山病死亡 2 2例 ,15例死于慢性充血性心力衰竭 (占 6 8.2 % ) ,7例死于猝死 (占 31.8% ) ;④病区 3～ 15岁儿童发硒含量 8年均达到非病区水平。结论 陕西省黄陵县克山病的发病呈平稳低发态势 ,但潜在型克山病仍有新发
Objective To observe the changes of Keshan disease and related factors in Kuling Mountain of Huangling County, Shaanxi Province in the past eight years. Methods Six seriously ill villages in Huangling County were selected to set up monitoring points, and residents in this area were listed as monitoring objects. The incidence of Keshan disease at this monitoring point and the environmental selenium level in 3-15-year-old children were monitored for 8 consecutive years from 1995 to 2002. Results ① The detection rates of latent and chronic Keshan disease were 4.3%, 3.6%, 7.5%, 8.0% and 8.5% respectively in 1995, 1997, 1999, 2000 and 2002; ② Potential The new incidence of Keshan disease in 1995, 1997, 1999, 2000 and 2002 were 55.66, 53.5, 30.5, 19.5, 30 and 25,000 respectively ; ③The death of 8 patients with chronic Keshan disease in 8 years in the county was 22, 15 died of chronic congestive heart failure (6 8.2%), 7 died of sudden death (31.8%), and 3 ~ 15 years Selenium content of children reached non-ward levels for 8 years. Conclusion The incidence of Keshan disease in Huangling County, Shaanxi Province showed a steady and low incidence trend, but there were still new developments in latent Keshan disease
