目的掌握全市大骨节病病情动态,为防治决策提供依据。方法在病区县各选4个当前病情最重的村作为监测点,调查7～16岁儿童大骨节病临床患病情况,7～12岁儿童大骨节病X线阳性检出情况及13～16岁儿童临床诊断I度及以上病人X线符合情况。按大骨节病诊断标准,X线片由省级专家组集体阅读,阳性X线片由国家专家组复核并作出最终诊断,统计检出率。收集相关村屯人口、饮水、粮食供给等方面的基本资料。结果 3个县12个监测点临床I度及以上患者平均检出率为1.67%,长岭县检出率0.8%,前郭县检出率3.4%,乾安县检出率2.82%。7～12岁儿童X线阳性平均检出率为1.08%。长岭县检出率1.81%,前郭县检出率0.91%,乾安县未检出。结论通过改水换粮,X线检出率均很低,儿童X线改变为干骺端和骨端型,大骨节病病情处于稳步下降的趋势。长岭、前郭二县在监测中都有X线阳性检出,而所有病区全部建井并持续使用的乾安县监测中未有X线阳性检出。提示我们饮浅井水与病情有一定关系,生活条件的改善并不能完全排除致病因子的作用,需坚持落实大骨节病的防治措施,尽早控制大骨节病发生。继续加强政府投资、管理力度,加大大骨节病区换粮力度,并且重新在病区修建深水井,更加深入地开展监测工作。
Objective To master the status of Kashin-Beck disease in the city and provide basis for prevention and control decision-making. Methods In the ward counties selected the four most serious illness village as a monitoring point to investigate the clinical prevalence of Kashin-Beck disease in children aged 7 to 16, 7 to 12-year-old children with Kashin-Beck disease X-ray detection of positive and 13 ~ 16-year-old children with clinical diagnosis of I degree and above the X-ray patient compliance. According to the diagnostic criteria of Kashin-Beck disease, X-ray film was read by the provincial expert group collectively. The positive X-ray film was reviewed by the national expert group and the final diagnosis was made. The detection rate was statistically analyzed. Collect relevant village population, drinking water, food supply and other aspects of the basic information. Results The average detection rate was 1.67% in I and above 12 clinics. The detection rate was 0.8% in Changling County, 3.4% in Qian Guo County and 2.82% in Qian’an County. The average positive rate of X-ray in 7 ~ 12-year-old children was 1.08%. Changling County, the detection rate of 1.81%, the former Guo County detection rate of 0.91%, Qian’an County was not detected. Conclusion By changing the water for food, X-ray detection rate is very low, children’s X-ray changes to metaphyseal and end-bone type, Kashin-Beck disease is in a steady decline. There were X-ray positive detection in Changling and Qianqiang counties, but no X-ray was detected in all the wards in Qian’an County. Prompted us to drink shallow well water has a certain relationship with the disease, the improvement of living conditions and can not completely rule out the role of causal agents, need to implement the prevention and treatment of Kashin-Beck disease as soon as possible control of Kaschin-Beck disease. We will continue to strengthen government investment and management and increase the intensity of food exchange in KBD. We will rebuild deep wells in the ward and conduct more intensive monitoring.
