Zoucheng village forests and Keshan disease related factors


001) 06-629--01 Keshan disease control to understand the situation, investigate the cause and prevention strategies, monitoring of standards in accordance with Keshan disease, in August 2000 Keshan disease on heavy Zoucheng Zhang Zhuang (province grams Hill disease surveillance points) conducted a survey of key population condition,[link widoczny dla zalogowanych], and the ward residents selenium levels internal and external environment, economic conditions and the per capita share of grain was tested. 1 object focus groups and methods 1.1 Detection of Zhang Zhuang Village, 3 ~ l4-year-old forests and 15 years of age all part of a total of 596 suspected patients (male 367, female 229), the general physical examination and ECG tracings, heart suspected abnormal cardiac anteroposterior X-ray. 1.2 Hair selenium,[link widoczny dla zalogowanych], Selenium in the forests of the village food the focus of subjects randomly selected from 43 populations, each collected after the occipital hair 1g; subjects in the same village, 83 households were randomly collected among residents in the food production for copies of the l (wheat, corn 3O 28 copies, from Sweet 25). With 2,3 _ II: amino naphthalene fluorescence (reference standards provided by the Shanghai Institute of Atomic Energy Research Institute, lot number GBW009101) detected selenium, apparatus for the Hitachi 850 fluorescence spectrophotometer, and the per capita income of 1.3 Food survey from the forests of the village residents income year, the per capita share of grain and its composition. 1.4 g Mountain pain was diagnosed GB70211997 ~ Keshan disease diagnostic criteria, 2 Results 2.1 The basic situation of residents of the village of Zhang Zhuang forests 3620 people, 4,080 acres of farmland in 2000, the per capita income of 1,200 yuan; per capita grain 285kg, including wheat, 50kg, maize 50kg,[link widoczny dla zalogowanych], Shugan 125kg, other grains 60kg. Economic income than in 1995 (per 960) increased by 25. Past the village forests occurred in 18 cases of Keshan disease patients, 15 patients died, 3 patients are alive. 2.2 Check the forests focus groups focus groups in 596 villages,[link widoczny dla zalogowanych], found 22 cases of Keshan disease patients, the detection rate of 3.69. One slow-type l patients of potential unit tl pay Nanning City, Shandong Province Health and Epidemic Prevention Station 2721452 City Health and Epidemic Prevention Station of Shandong Province Research�� 629 * 21 cases in type; 18 males and 4 females. ECG was found 37 suspicious,[link widoczny dla zalogowanych], which I degree atrioventricular block 14. 235 total subjects; short PR syndrome 7, QRS low-voltage 4, atrioventricular nodal rhythm walk 2. Incomplete right bundle branch block 2, the other abnormalities 9. These 37 people x-ray, cardiothoracic ratio from 0.51 to 0.60 (normal <0.5O) 7, accounting for 18.92, of which 5 people 0.5l ~ 0.55 (the heart of light degree of hypertrophy), 2 person 0.56 0.60 (moderate cardiac hypertrophy.) 2,3 Hair selenium, Determination of selenium content of selenium food 43 hair was (0.323 �� 0.059) mg / kg, significantly higher than normal (0.2 ~ 0.3mg/kg); 28 were wheat ( 0.019 �� 0.006) mg / kg, 30 were maize (0.012 �� 0.003) mg / kg, 25 were from Sweet as (0.012 �� 0.004) mg / kg. 3 Discussion Keshan Zoucheng is seriously ill ward of Shandong Province, this key population of 596 were detected, detection rate was 3.69 Keshan disease; ECG changed significantly accounted for 6.21 (37), which l4 cases I degree AV block; X-ray examination in 7 cases of Keshan disease diagnostic character sets, including 2 patients with moderate cardiac hypertrophy. Should attach great importance to this. The test results, hair Se than in 1995 (0.172mg/kg) increased by 87.8O, selenium content of food in no significant change, suggesting that as people's living standards, diet has changed, Se big firefly high food intake, Keshan disease-related factors continue to improve, the situation changes and the stability condition is closely linked to 0], but also for future research etiology of Keshan disease and control strategies to provide a scientific basis for 4
