RESUMO
Objective To study the serum level of macrophage inflammatory protein-1α(MIP-1α) and interferon gamma inducible protein-10 (IP-10) in acute myelogenous leukemia (AML) and clarify their clinical significance. Methods Enzyme-linked immunosorbent assay was used to detect the level of MIP-1α and IP-10 in serum samples from 34 AML patients(observation group) and 20 volunteers (normal control group). Results The levels of MIP-1αand IP-10 in observation group before induction chemotherapy were significantly higher than those in normal control group (P<0.05). The levels of MIP-1αand IP-10 in observation group after induction chemotherapy were decreased, and significantly lower than those before induction chemotherapy (P<0.05). After treatment for one course, 21 patients reached complete remission (CR), and 13 patients did not reach CR. The levels of MIP-1αand IP-10 in CR group had no significant difference compared with those in normal control group (P<0.05), but the levels of MIP-1αand IP-10 in none CR group were significantly higher than those in normal control group and CR group (P<0.05). The drop percentage of MIP- 1αlevels in CR group and none CR group was (32.51 ± 10.34)% and (10.57 ± 10.39)%, and there was significant difference (P<0.05). The drop percentage of IP-10 levelsin CR group and none CR group was(45.94 ± 13.68)% and (31.17 ± 11.85)%, and there was significant difference (P<0.05). Liner correlation analysis revealed that the levels of MIP-1αand IP-10 had significantly positive correlation in AML patients (r=0.652, P<0.05). Conclusions Different expressions of serum MIP-1α and IP-10 are found before and after induction chemotherapy AML patients, and there is significant correlation. Combined detection of serum MIP-1αand IP-10 may be used as an index to monitor clinical stages and prognosis.
RESUMO
Objective To study the expression of macrophage inflammatory protein-1α(MIP-1α),inter-feron gamma inducible protein 10(IP -10)and angiopoietin -1 (Ang -1)in primary acute myelogenous leukemia (AML),and clarify their clinical significance.Methods ELISA was used to detect the expressions of MIP -1α,IP-10 and Ang -1 in serum samples from 54 AML patients(observation group),and twenty volunteers(normal control group).Results The expression levels of MIP -1α,IP -10 and Ang -1 in the observation group[(198.813 ± 53.923)pg/mL,(2.332 ±0.745)ng/mL,(1.593 ±0.447)ng/mL]were significantly higher than the normal control group[(153.309 ±44.475)pg/mL,(1.569 ±0.485)ng/mL,(0.838 ±0.333)ng/mL](t =3.369,5.133,6.856, all P 0.05).There were remarkable correlation between the serum expression levels of MIP -1αand Ang -1 (r =0.324,P <0.05).Conclusion There are differences of serum MIP -1α, IP -10 and Ang -1 in the different NCCN prognosis groups,which reflect they may have certain guiding significance in the choice of clinical treatment and the prognosis for newly diagnosed AML.
