本文报告了1986年以来,我们在全省范围内进行了10个县(点)大骨节病流行病学调查。1、材料选择不同主食、克山病区与非病区作为调查点,重点放在与我省毗邻有大骨节病发病的四川,西藏相连地带。普查对象为年龄在5～15岁的农业人口。2、10个点海拔分布在580～3310米之间,有克山病发病的点7个,以大米为主食的点8个,以玉米为主食的点1个,青稞为主食的点1个。临床共检查4978人,摄片4441人,未发现大骨节病人。有 X 线改变291人,占总摄片人数的6.6%,5～10岁有改变的占1.0%、11～15岁有改变占5.6%。男性检查2538人,有改变144人,占男性被检数5.7%,女性检查1903人,有改变147人,占女性被检数7.7%,各点检出率在4.0～9.3%之间。3、手部 X 线改变291人,其中干骺端改变检出278人,占总摄片数的6.1%,骨端改变22人,占总摄片数的0.49%,其内干骺端、骨端同时改变9人。干骺端改变表现为不规整及硬化,骨端改变表现为边缘尖锐及不整和凹入。4、10个点的儿童发硒值最低为0.067±0.054ppm,低于0.154±0.037ppm 的有6个点。主粮硒在0.008～0.026ppm之间的有8个点,有7个点是克山病区。
This article reports that since 1986, we conducted an epidemiological survey of Kashin-Beck disease in 10 counties (spots) across the province. 1, different staple food materials selection, Keshan ward and non-ward as a survey point, with emphasis on the province and adjacent to the incidence of KBD in Sichuan, Tibet connected belt. Census for the age of 5 to 15 years of agricultural population. 2,10 points altitude distribution in the 580 ~ 3310 meters, Keshan disease incidence of 7 points to rice as the staple food point 8, with corn as the staple food point 1, barley staple food point 1 . A total of 4978 people were examined, 4441 were taken and no patients with bones were found. X-ray changes 291 people, accounting for 6.6% of the total number of radiographs, 5 to 10 years of age have changed 1.0%, 11 to 15 years of age have changed 5.6%. There were 2538 males, 144 were changed, accounting for 5.7% of males and 1903 of females, 147 were changed, accounting for 7.7% of females, and the detection rates were between 4.0% and 9.3%. 3, hand X-ray changes in 291 people, of which 278 were metaphyseal changes detected, accounting for 6.1% of the total number of radiographs, bone end changes 22, accounting for 0.49% of the total number of radiographs, which the metaphysis, Bone at the same time change 9 people. Metaphyseal changes showed irregular and hardening, changes in the performance of the bony tip sharp and irregular and concave. The lowest selenium value in children with 4 and 10 points was 0.067 ± 0.054ppm, and there were 6 points less than 0.154 ± 0.037ppm. The staple food selenium has 8 points between 0.008 and 0.026ppm, and 7 points are the Keshan ward.
