血小板减少症是新生儿脓毒症常见的血液并发症．血小板生成素（ＴＰＯ）是调节巨核细胞生成及血小板产生的主要因子．该研究的目的是检测新生儿感染时循环中ＴＰＯ水平是否发生变化及其与血小板计数的关系． 方法１９９７－１９９８年６个月间新生儿加强监护病房的３６例新生儿 Thrombocytopenia is a common blood complication of neonatal sepsis. Thrombopoietin (TPO) is a major regulator of megakaryocytopoiesis and platelet production. The purpose of this study was to determine if there is any change in circulating TPO levels during neonatal infection and its relationship with platelet count. Methods Thirty-six neonates with intensive care units during the six-month period 1997-1998 were enrolled
