Objective: To explore the role of human hematopoietic growth factors (HGFs) in proliferation and differentiation of cord blood CD34+ cells. Methods: Human cord blood mononuclear cells (MNC) were cultured with different combinations of HGFs (including rhIL-1,rhIL-3, rhIL-6, rhG-CSF, rhGM-CSF and rhSCF). The expansion folds of MNC, the changes of cellular surface markers by FACS, and CFU-GM of hematopoietic cells were observed. Results: The total nucleated cells expanded by 44 folds after cultured with 6 cytokines for 20 days. The number of CFU-GM increased by 14 .74 folds after cultured in liquid for 8 days, but decreased heavily after 18 days. The total number of CD34+ cells increased by 127. 79 ~ 196 .40 folds at 6 to 8 day, but decreased to 101.51 folds at 18 day. Conclusion: Human hematopoietic growth factors can increase the expansion of cord blood CD34+ cells and CFU-GM significantly.

Objective To study the relationship of concentraions of trace elements and the SOD, GSH-Ps activities in plasma following severe burn injury, and provide witness for clinical treatment of trace elements disorder in burned patients. Methods The plasma and urine from 67 severely burned patients in our hospital were collected on day 2, 4, 6, 8, 10, 15, 20, 30 after hospitalization. Trace element levels were determined by atomic absorption spectrophotometry. The vital force of SOD and GSH-Px were measured in plasma with the kits provided by Nanjing Jiancheng bioengineering research institute. Results The ion concentration of Cu in serum got higher and that of Zn got lower after burn, but that of Mn, Se was of no significance. The concentration of Cu, Zn, Mn, Se in urine were increased. The enzymatic activities of T-SOD and Cu, Zn-SOD as well as GSH-Px decreased from the early period to the metaphase. Conclusion For a great deal of oxygen free radicals released by tissues, SOD and GSH-Px were consumed and their concentration decreased in early stage after burn. Due to the trace elements released into blood by destroyed tissues and their increased excretion from urine, tissues could not generate adequate antioxidase, resulting in weak ability against inflammation and poor tissue repair. Our result provides a theoretical clue for the replenishment of trace elements for severely burned patients in early and middle stage and offer a clue to pathology and etiological treatment of burn.
