纤维结合蛋白(Fibronectin,FN)作为一种非特异性调理素具有增强吞噬,调节粘附和促进网状内皮系统清除功能的作用。有报道成人和新生儿败血症患者血浆FN 降低。本研究对血浆FN 测定在早期婴儿细菌感染中的预测价值进行了探讨。病人和方法选择100名年龄2～83天(出生体重>2000g,围产期无异常)、疑诊败血症而入院的婴儿为研究组;60名同龄正常儿为对照组。研 Fibronectin (FN), as a non-specific opsonin, has the function of enhancing phagocytosis, regulating adhesion and promoting the clearance function of reticuloendothelial system. It has been reported in adults and neonatal sepsis plasma FN decreased. This study explored the predictive value of plasma FN assay in early infant bacterial infections. The patients and methods selected 100 patients aged 2 to 83 days (birth weight> 2000g, no abnormal perinatal), infants admitted to hospital with suspected sepsis as study group and 60 normal children as control group. research
