湖北省唯一克山病区发现部分居民有关节肿胀变形,经调查243人中,主诉关节疼痛162人,手指关节肿胀变形28人,X 线有改变34人,病区儿童41例中有35例骨龄发育严重落后。对照点未发现上述改变。病区大米硒均值为18μg/kg,儿童发硒均值125μg/kg,水碘均值为0.91μg/L:对照点大米硒均值29μg/kg,儿童发硒均值为437μg/kg,水碘均值2.34μg/L。结果提示:该病区成人和儿童可能因低硒导致关节软骨坏死,低硒,低碘导致骨龄落后。
In the only Keshan Ward in Hubei Province, some residents were found to have swollen and deformed joints. Of the 243 people surveyed, 162 complained of joint pain and 28 swollen fingers, 34 of whom had X-ray changes. Of the 41 patients in the ward, 35 Bone age seriously underdeveloped.

The average selenium content of rice in the ward was 18μg / kg, the average value of selenium in children was 125μg / kg, the average value of iodine in water was 0.91μg / L: the mean value of selenium in control point was 29μg / kg, the average value of selenium in children was 437μg / kg, / L. The results suggest that adults and children in this ward may be due to low selenium lead to articular cartilage necrosis, low selenium, low iodine lead to bone age.
