2007-2009年甘肃省平凉市克山病病情监测结果分析

目的 掌握甘肃省平凉市克山病病情现状及消长趋势,评估防控效果,为今后克山病防治提供科学依据.方法 2007-2009年,按<中央补助地方公共卫生专项资金地方病防治项目克山病监测技术方案>及<克山病诊断标准>(GB 17021-1997),对甘肃省平凉市9个监测点的常住居民进行临床检查并描记心电图,拍摄患者和疑似病例X线胸片;采集儿童、男性成人和妇女的发样及其食用玉米、小麦样品,分别用2.3-二氨基萘荧光法进行含硒量测定.结果 3年共调查病区居民5846人,检出克山病247例,检出率为4.23%(247/5846).其中潜在型克山病214例,检出率为3.66%(214/5846);慢型克山病33例,检出率为0.56%(33/5846);无急型、亚急型克山病检出.检出异常心电图764例,检出率为13.07%(764/5846).对207例患者和疑似病例进行X线胸部摄片检查,心脏增大者80例,检出率为38.6%(80/207).共采集发样262份,发硒为(0.279±0.098)mg/kg.采集玉米样品9份,含硒量为(0.0079±0.0029)mg/kg;小麦31份,含硒量为(0.0104±0.0078)mg/kg.结论 甘肃省平凉市克山病病情总体处于稳定消退趋势,但病区仍有一定数量的潜在型、慢型克山病散在新发病例出现,提示病情监测、综合防治和现症病人的治疗管理仍是今后克山病防治的重点.

Abstract：

Objective To unveil the current situation and bends of Keshan disease in Pingliang city of Gansu province, to evaluate the outcome of related prevention and control measures, and to provide scientific basis for further prevention and treatment of the disease. Methods According to the "the central allowance local public health special funds endemic disease prevention programs grams mountain monitoring programme" and "the diagnostic criteria for Keshan disease" (GB 17021-1997), between 2007 and 2009, local residents from nine monitoring points in Pingliang city of Gansu province were clinically examined, and electrocardiography(ECG) tracings and Xray were taken of suspected cases. Corn, wheat samples and hair samples of children, adults and women were collected, and selenium content of these samples was determined by 2.3-2-amino-naphthalene fluorescence method. Results A total of 5846 residents were surveyed in 3 years, 247 cases of Keshan patients were detected, with a detection rate of 4.23%(247/5846), of which potential cases of Keshan disease 214, the detection rate was 3.66% (214/5846); chronic Keshan disease 33 cases, the detection rate was 0.56% (33/5846); no acute type and subacute Keshan disease detected. A total of 764 abnormal ECG cases were detected, and abnormal detection rate was 13.07%(764/5846). Two hundred and seven cases of suspected patients were examined by chest X-ray, 80 cardiac enlargement cases were detected, the detection rate was 38.6% (80/207). The 262 hair samples of children, adults and women were analyzed, hair selenium was (0.279 ± 0.098)mg/kg. Of the 9 corn and 31 wheat samples collected, corn selenium was (0.0079 ± 0.0029)mg/kg; wheat selenium was (0.0104 ± 0.0078)mg/kg. Conclusions Overall Keshan disease is in a stable and subsided trend in Pingliang city of Gansu province, but there are still a number of potential chronic types, sporadic new cases, suggesting that the disease monitoring, comprehensive prevention and treatment of the patients are the focus.
