摘要:

目的 建立北京地区0~12岁儿童末梢全血中钙、镁、锰、铁、铜、硒、锌、汞、铅和镉10种矿物元素的参考区间,探讨矮小症和抽动障碍与全血矿物元素之间的关系。方法 选取2023年7月—2024年4月北京市顺义区妇幼保健院行健康体检的表观健康儿童1 382名,按性别和年龄[婴幼儿(≤2岁)组、学龄前期(3~5岁)组、学龄期(6~12岁)组]分别分组。采用电感耦合等离子体质谱法(ICP-MS)检测末梢血10种矿物元素水平,采用百分位数法建立相应的参考区间。另选取2023年7月—2024年4月北京市顺义区妇幼保健院矮小症患儿61例(矮小症组)、抽动障碍患儿78例(抽动障碍组)、表观健康儿童152名(正常对照组),采用ICP-MS检测静脉血样本中10种矿物元素水平。采用Logistic回归分析评估矮小症和抽动障碍发生的影响因素。采用受试者工作特征(ROC)曲线评估各项指标诊断矮小症和抽动障碍的效能。结果 男童组和女童组锰、铜、铅、镉水平差异有统计学意义(P<0.05),其他元素2个组之间差异无统计学意义(P>0.05)。基于性别和年龄分别建立锰、铜、铅、镉4种元素的参考区间,基于年龄建立钙、镁、铁、硒、锌、汞6种元素的参考区间。矮小症组镉、汞和铅水平均高于正常对照组(P<0.05);抽动障碍组钙水平低于正常对照组(P<0.05),锌、汞和铅水平高于正常对照组(P<0.05) 。汞和铅水平升高是矮小症发生的独立危险因素(P<0.05),汞、铅单项检测和联合检测诊断矮小症的曲线下面积(AUC)分别为0.590、0.721、0.746。镉、汞和铅水平升高是抽动障碍发生的独立危险因素(P<0.05),镉、汞、铅单项检测和联合检测诊断抽动障碍的AUC分别为0.524、0.585、0.591、0.665。结论 初步建立了基于ICP-MS的北京地区不同性别、不同年龄段儿童末梢血钙、镁、锰、铁、铜、硒、锌、汞、铅、镉的参考区间。矮小症和抽动障碍均与矿物元素水平有一定的关系。

Abstract:

Objective To establish reference intervals for 10 mineral elements (calcium, magnesium, manganese, iron, copper, selenium, zinc, mercury, lead and cadmium) in capillary whole blood of children aged 0-12 years in Beijing, and to investigate the relationship between these elements and short stature and tic disorders. Methods A total of 1 382 apparently healthy children undergoing physical examinations at Shunyi Maternal and Children's Hospital of Beijing Children's Hospital from July 2023 to April 2024 were enrolled. They were classified by genders and ages [infants/toddlers(≤2 years),preschool(3-5 years) and school-age(6-12 years)]. The levels of the 10 elements were determined using inductively coupled plasma mass spectrometry(ICP-MS),and corresponding reference intervals were established using the percentile method. Additionally,61 children with short stature(short stature group),78 children with tic disorders(tic disorder group) and 152 healthy children undergoing physical examinations during the same period(healthy control group) were enrolled. Venous blood samples from these groups were analyzed for the 10 elements using ICP-MS. Logistic regression analysis was used to assess influencing factors for the occurrence of short stature and tic disorders. Receiver operating characteristic(ROC) curve analysis was performed to evaluate the diagnostic efficacy of each indicator for short stature and tic disorders. Results Statistically significant differences were observed between boys and girls for manganese,copper,lead and cadmium levels(P<0.05),while no statistically significant differences were found for the other elements(P>0.05). Gender- and age-specific reference intervals were established for manganese,copper,lead and cadmium. Age-specific reference intervals were established for calcium,magnesium,iron,selenium,zinc and mercury. Cadmium,mercury,and lead levels in short stature group were higher than those in healthy control group(P<0.05). Calcium levels in tic disorder group were lower than those in healthy control group,while zinc,mercury and lead levels were higher(P<0.05). Elevated mercury and lead levels were identified as independent risk factors for short stature(P<0.05). The areas under curves(AUC) for diagnosing short stature using mercury,lead and their combined determination were 0.590,0.721 and 0.746,respectively. Elevated cadmium,mercury and lead levels were identified as independent risk factors for tic disorders(P<0.05). The AUC for diagnosing tic disorders using cadmium,mercury,lead and their combined determination were 0.524,0.585,0.591 and 0.665,respectively. Conclusions The reference intervals for calcium, magnesium, manganese, iron, copper, selenium, zinc, mercury, lead and cadmium have been established in capillary whole blood of children in Beijing, which are stratified by gender and age groups using ICP-MS. Both short stature and tic disorders show carrelations with the levels of certain mineral elements.
