RESUMO
Objective To study the correlation between ABO blood groups and leukemia and lymphoma, and the regional difference. Methods A case-control study had been conducted. The distribution of ABO blood groups was investigated in leukemia patients, lymphoma patients and controls, respectively. Also ABO blood group distribution of leukemia and lymphoma were compared in different areas. Results The distribution of ABO blood groups between patients with acute non-lymphocytic leukemia, acute lymphocytic leukemia, non-Hodgkin lymphoma and health person was significantly different (χ2 = 21.23, χ2 =8.36, χ2 = 9.39,P <0.05). There were regional differences in the ABO blood groups distribution of leukemia and lymphoma,especially ABO blood groups were significantly different in leukemia patients (χ2 = 50.65, P <0.05).Conclusion ABO blood groups might be a genetic susceptible factor of leukemia and lymphoma, but the geography might be a major influential factor.
RESUMO
Aim To study the effects of ferulic acid (FA) on E-selectin expression in human umbilical vein endothelial cells (HUVECs) activated by lipopolysaccharide and leukocyte-endothelial cell adhesion. Methods The effects of FA on E-selectin and E-selectin mRNA expression were determined by flow cytometry and reverse transcription polymerase chain reaction. The effect of FA on HL60-HUVEC adhesion was evaluated with the method of staining the cells by Rose Bengal. Results The expression of tively). Conclusion FA can inhibit the expression of E-selectin and E-selectin mRNA and HL60-HUVEC adhesion. This may contribute to its protective effect against ischemia-reperfusion injury.
