摘　　要：目的研究婴儿气质与其出生时脐血CD4^＋、CD8^＋淋巴细胞百分数、绝对计数及CD4^＋/CD8^＋间的关系。方法取25例健康新生儿脐带血,采用流式细胞检测技术测CD4^＋、CD8^＋淋巴细胞百分数并计算绝对计数及CD4^＋/CD8^＋值,并在婴儿1-4个月（平均2.52个月）时,使用Carey小婴儿气质问卷（EITQ）及气质分析软件对气质的9个维度分别进行评分。结果CD4^＋淋巴细胞百分数与小婴儿气质维度中的坚持性存在负直线相关关系（r=-0.43P=0.033）;CD8^＋淋巴细胞百分数、CD4^＋及CD8^＋绝对计数及CD4^＋/CD8^＋值与小婴儿气质各维度无相关关系。结论婴儿气质与CD4^＋淋巴细胞百分数存在负相关;CD4^＋淋巴细胞百分数越低,婴儿坚持性可能越好。Objective To examine whether neonate′s cord blood T-lymphocytes is related to infant temperament.Methods Twenty-five healthy babies were randomly chosen in Changsha from Jul.2005 to Aug.2005 and their cord blood was drown when they were born. CD4^＋ and CD8^＋ counts, CD4^＋%, CD8^＋%, CD4^＋/ CD8^＋ratios were obtained using flow cytometry analysis. Infant temperament were measured after 1-4 months（ mean age 2.52 months） with parent response to carey revised infant temperament questionnaire（EITQ/RITQ） administered.Results The percentage of CD4^＋ T-cell subsets to total lymphocytes correlated negatively with persistence scores （r=-0.43 P=0.033）. However, CD8^＋%, CD8^＋ and CD4^＋ counts, CD4^＋/ CD8^＋ ratios were not correlated with temperament traits.Conclusions The lower CD4 %, the better infants＇ persistence.
