兒童急性白血病血清Hepcidin的表達及其與鐵代謝的關系
[Abstract]:BACKGROUND AND OBJECTIVE Hepcidin is considered to be a polypeptide synthesized and secreted by the liver and plays an important role in the regulation of iron metabolism in the body. Hepcidin expression in childhood acute leukemia (AL) and its relationship with iron metabolism were less. Enzyme-linked immunosorbent assay (ELISA) was used in this study. Mmunosorbent assay (ELISA) was used to detect the expression of hepcidin and IL-6 in serum of children with AL. Serum concentrations of transferrin (TRF), ferritin (FN) were detected. The mechanism of abnormal expression of hepcidin was analyzed. The relationship between abnormal expression of hepcidin and iron metabolism in children with AL was studied by correlation analysis. Sixty-three children with AL diagnosed in the pediatric ward of the First Affiliated Hospital of Zhengzhou University in November 15 were selected as the study subjects and 30 healthy children were selected as the control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of Hepcidin and IL-6 in the serum of children with AL at the beginning of treatment, after treatment and 30 healthy controls, and to detect the expression of TRF and FN in the serum of all subjects. Results 1 There was no significant difference in sex composition between AL group and healthy control group (_2 = 0.031, P = 0.031). The serum levels of hepcidin, IL-6, and iron metabolism index TRF, FN in the primary treatment group and the control group were significantly lower than those in the primary treatment group (P 0.001). The serum levels of hepcidin, IL-6 and FN in the primary treatment group were significantly higher than those in the control group (P 0.001). The levels of serum hepcidin, IL-6, iron metabolism index TRF and FN in AL remission group were higher than those in AL remission group (P 0.001). The levels of serum TRF in AL remission group were lower than those in AL remission group (P 0.001). There was no significant difference in serum levels of Hepcidin, IL-6, FN and TRF between remission group and non-remission group (P 0.05). Levels of serum hepcidin, IL-6 and serum hepcidin were significantly higher than those of remission group (P 0.001), and the correlation between serum hepcidin, iron metabolism index FN and TRF was statistically significant (P 0.001). Serum levels of hepcidin were positively correlated with serum levels of IL-6 (r = 0.866, P 0.001), serum levels of TRF were negatively correlated with serum levels of hepcidin (r = - 0.834, P 0.001), serum levels of FN were positively correlated with serum levels of hepcidin (r = 0.750, P 0.001), and the differences were statistically significant. Abnormal expression of pcidin and disorder of iron metabolism. 2. The serum levels of hepcidin, IL-6 and FN in children with AL were higher than those in healthy children, and these molecular levels could be used as auxiliary diagnostic indicators for children with AL. The serum levels of Hepcidin, IL-6, FN and TR F were different before and after chemotherapy remission and between remission and non-remission groups, suggesting that the levels of each indicator were different. The expression of hepcidin in serum was positively correlated with that of IL-6, suggesting that IL-6 was one of the reasons for the elevated level of hepcidin in children with AL, the expression of TRF in serum was negatively correlated with that of Hepcidin, and the expression of FN in serum was negatively correlated with that of Hepcidin. The level is positively correlated, suggesting that Hepcidin is involved in the disorder of AL iron metabolism in children.
