2415例可疑食用含三聚氰胺奶粉儿童筛查分析

目的探讨食用含三聚氰胺奶粉对儿童泌尿系统的影响。方法对2415例可疑食用含三聚氰胺奶粉儿童进行喂养史、泌尿系统B超和小便常规筛查分析。结果含三聚氰胺三鹿牌奶粉致集合系统分离检出率2.89％，较其他含三聚氰胺类奶粉0.71％，差异有显著性统计学意义（P〈0.01），较未公布类0.42％亦有统计学意义（P〈0.05）。其中食用含三聚氰胺三鹿牌奶粉婴幼儿和3岁以上儿童致泌尿系统结晶检出率分别为12.6％、7.46％，差异有统计学意义（P〈0.05）；食用含三聚氰胺奶粉服用时间（14.77±16.95）月，与泌尿系统结晶（0.0243±0.0691）cm相关系数为r=0.0665，差异有显著性统计学意义（P〈0.01）。结论食用含三聚氰胺奶粉儿童造成泌尿系统的损害程度对婴幼儿损害最大，特别是致集合系统分离，与含三聚氰胺的含量、食量、服食时间等多因素相关。

Screening analysis of 2415 children suspected of consuming milk powder containing melamine

Objective To explore the effect of children＇s consuming milk powder containing melamine on their urinary system. Methods Feeding history, urinary system B - and urinative convention of 2415 children suspected of consuming the milk powder containing melamine were screened and analyzed. Results The detection rate of Sanlu - induced separation of the collection system, 2.89%, was significantly different statistically from other milk powder that the government confirmed contained melamine 0.71% （ P 〈 0.01）, and it was different statistically from the milk powder that the government didn＇t con- firm contained melamine 0.42% （P 〈 0.05 ）. The detection rate of Sanlu - induced crystallization on babies and children a-bove 3 years were 12.6% ,7.46% （ P 〈 0. 05 ） respectively, they were different statistically. The coefficient concerned with the period of taking the milk powder containing melamine （14.77±16.95） months and urinary system crystallization （0.0243±0.0691）cm was r=0.0665（P〈0.01）. They showed significant difference statistically. Conclusion Thecon-sumption of the milk powder containing melamine does a most serious damage to the urinary system of babies and infants. Separation of the collection system is closely related to the content of melamine in milk powder, the dosage and the period of consuming the milk powder.
