Objective:To detect Wnt5a gene expression and NPM1 gene in chronic myeloid leukemia bone marrow cells and to explore its relevance and significance.Methods:Sixty cases of chronic myeloid leukemia patients in our hospital were included in the experimental group, taking up 20 cases in the blastic phase, 20 cases in the accelerated phase, and 20 cases in the chronic phase; and 60 cases with benign hematologic disease were included in the control group. Cultured bone marrow cells were detected by RT-PCR methods to analyze the significance of Wnt5a and NPM1 gene expressions.Results:Wnt5a mRNA in the three sub-groups of the experimental group had low semi-quantitative mean values and positive rates compared with the control group. NPM1 mRNA positive rates and median expression levels were higher, and the difference was statistically significant. In the three subgroups of the experimental group, Wnt5a mRNA semi-quantitative mean values and positive rates in the blastic phase and accelerated phase were low, while NPM1 mRNA positive rates and median expression levels were higher; and the difference was statistically significant. Wnt5a and NPM1 expression levels in patients' white blood cell count were associated with bone marrow blast cells; and the difference was statistically significant. However, this was not associated with age, hemoglobin content and platelet count; and the difference was not statistically significant.Conclusion: There is a certain degree of correlation between Wnt5a and NPM1 genes and the occurrence and development of chronic myeloid leukemia. Wnt5a gene may inhibit its occurrence, while NPM1 gene positivity promotes its progression, which may be applied in the diagnosis and treatment of chronic myeloid leukemia, providing a new way of analyzing prognosis and a theoretical basis for clinical application.
