摘要
目的:探讨白细胞分类计数对婴幼儿腹泻病的诊断价值。方法:采用常规白细胞计数方法得出各病例组测定值,确定有意义界值后得出各项的敏感性和特异性。结果:重型腹泻组中性粒细胞杆状核细胞数和B/N值明显高于非腹泻对照组和轻型腹泻组(P<0.01),中型腹泻组B/N值也高于非腹泻对照组(P<0.05)。各病例组间白细胞总数、淋巴细胞和中性粒细胞分叶核细胞增加并无差异(P>0.05)。中性粒细胞杆状核细胞数和B/N值对婴幼儿重型腹泻组的诊断敏感性分别为81.71%和84.76%,特异性分别为75.61%和78.05%。两项共同诊断的敏感性和特异性达85.98%和79.68%。结论:白细胞计数总数和淋巴细胞的增加对婴幼儿腹泻病的诊断意义不大,中性粒细胞杆状核细胞绝对数和B/N值确有重要价值。B/N值>0.10应考虑是由重要致病微生物引起。
Objective：To explore the diagnostic value of leucocyte differential count to infantile diarrhea disease. Methods：Tbe results of WBC and differential eount were analysed and then,the susceptible and specific data were measured after the borderline determination.Resalts：Signifieant differences were observed in Neutrophilic band form and B/N value between heavy group and light group（ P 〈 0.01 ）, and B/N value of medium group was much different from the comparison group（ P 〈 0.05）. No significant differ- enees were observed in WBC,lymphoeyte and segmented neutrophil of all groups （ P 〉 0.05） .The sensitivity and the specificity of neutrophilic band form and B/N value to the heavy group was 85.98% ,84.76% and 75.61% ,78.05% respectively and that would reach 85.98% and 79.68%.wben they had been used to diagnosis together. Conclusion： There no diagnosis value of WBC and lymphocyte to infant diarrhea disease, but neutrophilic band form and B/N value are important for the infant diarrbea diagnosis. Infantile diarrhea disease is likely to be caused by important microbe. When B/N 〉 0.10.
