摘要: 慢性氟暴露是世界范围内的公共卫生问题之一.为研究燃煤污染型氟中毒患者中氟暴露、骨相损伤程度与骨形成标志物血清碱性磷酸酶(ALP)、骨钙素(BGP)之间的相关关系,以贵州省织金县荷花村(燃煤污染型地方性氟中毒病区)和安顺市张官村(非氟暴露村)为调查点,采集环境样品,采用氟离子选择电极法测定环境介质及食物中的氟含量.在知情同意的原则下,对295例氟暴露和85例非氟暴露调查对象进行氟斑牙、氟骨症诊断;收集其尿液及外周血,测定尿氟(UF)浓度、ALP活性和BGP含量.结果表明: 病区环境中大米、辣椒、玉米、饮水、黏土、菜土、煤以及室内外空气氟含量均明显高于对照区,但较以往报道数据降低;随着尿氟浓度的升高,ALP活性、BGP含量显著升高,氟骨症病情差异有统计学意义,氟斑牙病情差异无统计学意义;氟骨症病情与ALP活性、BGP含量呈正相关.表明燃煤污染型低氟暴露可引起人群的骨相损害,且ALP、BGP可用于评估氟骨症患者骨转换情况,在氟骨症的辅助诊断、疗效评估中有着一定的应用价值.

Abstract: Chronic exposure to fluoride is a public health problem worldwide. We explored the relationship between fluoride exposure, orthopedic injuries and bone formation markers alkaline phosphatase (ALP), bone Gla protein (BGP) in participants with coal-burning fluorosis in Hehua Village (coal-burning fluorosis endemic area) in Zhijin County of Guizhou Province and Zhangguan Village (non-fluoride contaminated area) in Anshun City of Guizhou Province. Environmental samples were collected and fluoride contents were examined using a fluoride ion-selective electrode. Dental fluorosis and skeletal fluorosis of 295 participants from Hehua Village and 85 participants from Zhangguan Village were diagnosed with informed consent. Urinary samples and peripheral blood samples were collected from the participants to determine urinary fluoride (UF), ALP acti-vity, and BGP content. The results showed that fluoride contents in rice, pepper, corn, drinking water, clay, vegetable-grown soil, coal and indoor and outdoor air were significantly higher than those in the control area, but lower than the previously reported values. With the increases of UF concentration, the ALP activity and BGP content significantly increased, the severity of skeletal fluorosis was greater, but with no significant changes in dental fluorosis. There was positive correlation between the severity of skeletal fluorosis and ALP activity, BGP content. These results indicated that low fluoride exposure could cause orthopedic injuries. ALP and BGP could be used to eva-luate the bone turnover in patients with skeletal fluorosis, which would be useful in the auxiliary diagnosis and therapeutic evaluation of skeletal fluorosis.
