The results of cytokine detection showed that compared to the healthy control group, the serum levels of CCL3, CCL4, G‐CSF and sICAM‐1 were significantly higher in both AML‐ND and AML‐PR groups (Figure 2), and an opposite result was observed in the expression of CXCL12, suggesting that CCL3, CCL4, G‐CSF, sICAM‐1 and CXCL12 may be helpful for AML diagnosis. The gene discussed is CXCL12; the disease is acute myeloid leukemia.
