摘 要:目的对贵州省水城县勺米乡与纸厂乡结合部地方性氟中毒(简称地氟病)村聚集性骨软化畸形儿童进行氟(F)、铝(A1)等多种元素测定,结合临床表现进行病因学诊断。方法2008年11月.对水城县纸厂乡与勺米乡结合部地氟病村寨骨软化畸形少年儿童聚集病例(病例组),在严格质量控制基础上,采集14个病例和同县非地氟病区13个同龄对照(对照组)的任意1次尿和枕部贴皮头发,进行氟(F)、铝(AL)、镉(Cr)、锰(Mn)、铁(Fe)、铜(Cu)、锌(Zn)、砷(As)、硒(Se)、锶(Sr)、钡(Ba)10种元素检测,数据用PEMS3.1医学软件统计包进行处理。结果病例组尿中F、AL、Mn、Cu、Sr、Se水平(1.18mg/L,112.6μg/L,6.62、29.86mg/L,177.5、4.23ng/L)与对照组(0.48、47.1、2.04、16.61mg/L,55.17、15.52ng/L)比较,差异均有统计学意义(t值分别为4.592、2.486、4.850、2.210、2.078、2.912,P均〈0.05)。病例组头发中A1、Mn、As、Sr、Ba、Fe、Se水平(59.27、5.26、0.956、1.497、1.287、297.13、0.454mg/kg)与对照组(18.69、0.72、1.094、0.621、0.675、69.022、1.323mg/kg)比较,差异有统计学意义(t值分别为4.583、6.318、3.309、2.704、5.606、6.294,P均〈0.05)。病例组尿中F与Al、Zn、As、Se的相关系数(r)均〉0.662(P均〈0.05),Al与Cu、Zn、As、Sr、Ba、Se的r均〉0.674(P均〈0.05),Se与Mn、Ba、Cu、Zn、Sr、As的r均〉0.694(P均〈0.05),Mn、Sr、As、Ba彼此之间r均〉0.550(P均〈0.05)。病例组头发中Al与Mn、Cr、Fe、Cu、As、Se的r均〉0.732(P均〈0.05),Ba与Mn、Cr、Fe、Sr,Mn与Cr、Fe,Cr与As,Cu与sr的r均〉0.686(P均〈0.05);对照组尿Cu与Zn、Se、Ba,Zn与Se、Ba,Cr与Mn、Ba的r均〉0.516(P均〈0.05);对照组头发中AlObjective To investigate the levels of trace elements such as fluorine(F), and aluminium (Al) etc. of osteomalacia malformation children and to make etiological diagnosis in reference with clinical manifestations. Methods Urine and occipitalia hairs of 14 diseased children(patient group) from endemic fluorosis area and 13 healthy children(control group) from non-endemic area were included in the study on November, 2008, and contents of 10 elements of fluorifie (F), aluminum (Al), chromium (Cr), manganese (Mn), ferrum (Fe), cuprum (Cu), zinc (Zn), arsenic(As), selenium(Se), strontium(St), and barium (Ba) were tested. The data were analyzed with medical soft package PEMS 3.1. Results Urinary contents of F, Al, Mn, Cu, Sr, and Se (1.18 mg/L, 112.6 μg/L, 6.62,29.86 mg/L, 177.5,4.23 ng/L) in patient group were significantly different from those in control group (0.48,47.1,2.04,16.61 mg/L, 55.17,15.52 ng/L, t = 4.592,2.486,4.850,2.210 2.078,2.912, all P 〈 0.05); Hair contents of Al, Mn, As, Sr, Ba, Fe, and Se in patient group(59.27,5.26,0.96,1.50,1.29,297.13,0.45 mg/kg) were significantly different from those of control group( 18.69,0.72,1.09,0.62,0.68,69.02,1.323 mg/kg, t = 4.583, 6.318,3.309,2.704,5.606,6.294, all P 〈 0.05); in patient group, the correlation coefficients of urinary Fe to Al, Zn, As, and Se were all bigger tan 0.662(all P 〈 0.05), those of urinary Se to Mn, Ba, Cu, Zn, Sr, and As were all bigger than 0.694(all P 〈 0.05), those among urinary Mn, Sr, As, and Ba were bigger than 0.550(all P 〈 0.05), those of hair Al to Mn, Cr, Fe, and Cu were bigger than 0.732(ali P 〈 0.05), those of hair Ba to Mn, Cr, Fe, and Sr, and of hair Mn to Cr and Fe, and those between Cr and As, between Cu and Sr were all bigger than 0.686 (all P 〈 0.05). In control group, the correlation coefficients of urinary Cu to Zn, Se, and Ba, those of Zn to Se and Ba, and those of Cr to Mn and'Ba were all bigger than 0.516(a
