【摘要】：[目的]探讨职业性铅接触工人血铅水平降低和神经传导速度增高之间的相关关系。[方法]分别于2007、2009年检测某电池厂空气铅浓度和60名职业铅接触工人与91名对照组工人的血铅值、运动神经及感觉神经传导速度,用协方差分析和相关分析对两者的变化关系进行探讨。[结果]铅接触组2009年度血铅水平较2007年度血铅水平有明显降低,由2007年度的(657.9±216.4)μg/L降至2009年度的(345.8±169.2)μg/L,与年龄、性别无关;2009年度感觉神经传导速度较2007年度有明显增加(P0.05)。男性工人正中神经、尺神经、腓浅神经感觉传导速度增加值与血铅下降值之间存在一定的相关关系,相关系数分别为0.365、0.276、0.17,具有统计学意义。对照组2009年度神经传导速度较2007年度未见明显变化。[结论]男性工人血铅下降水平和感觉神经传导速度增加值之间存在着一定的相关关系。可通过及时控制血铅水平,达到改善感觉神经传导速度的目的。
[Abstract]:[objective] to investigate the relationship between the decrease of blood lead level and the increase of nerve conduction velocity in workers exposed to occupational lead. [methods] the air lead concentration in a battery factory and 91 workers exposed to occupational lead were detected in 2007 and 2009, respectively. The blood lead value of the workers in the radiation group, The relationship between motor nerve and sensory nerve conduction velocity was studied by covariance analysis and correlation analysis. [results] the blood lead level in the lead exposure group in 2009 was significantly lower than that in 2007. From 657.9 卤216.4 渭 g / L in 2007 to 345.8 卤169.2) 渭 g / L in 2009, the sensory nerve conduction velocity in 2009 was significantly higher than that in 2007. There was a certain correlation between the increased value of sensory conduction velocity of superficial peroneal nerve and the drop of blood lead. The correlation coefficients were 0.365 and 0.276t 0.17, respectively, with statistical significance. There was no significant change in nerve conduction velocity in the control group in 2009 compared with 2007. [conclusion] there is a significant difference between the decrease of blood lead and the increase of sensory nerve conduction velocity in male workers. Through timely control of blood lead levels, To improve the sensory nerve conduction velocity.
