Abstract:
OBJECTIVE:To analyze the expression of lncRNA-MALAT1 in peripheral blood of patients with acute myeloid leukemia (AML) sepsis and explore its clinical significance.
METHODS:From March 2018 to March 2019, 95 confirmed AML patients including 43 sepsis infected cases and 52 uninfected cases were selected for treatment in the Department of Oncology and Hematology, The First People's Hospital of Longquanyi District. Their peripheral blood samples were taken as study samples, and the blood samples from 50 healthy people were used as control. RT-qPCR was used to detect lncRNA-MALAT1 expression level in samples from healthy group, uninfected group, and sepsis group. The correlation between lncRNA-MALAT1 expression level and clinical characteristics and prognosis of AML patients with sepsis were analyzed.
RESULTS:The expression level of lncRNA-MALAT1 in the sepsis group was significantly up-regulated compared with the healthy group and uninfected group (P<0.05), while there was no significant difference between the healthy group and uninfected group (P>0.05). In AML patients with sepsis, the expression of lncRNA-MALAT1 was associated with clinical characteristics such as NCCN risk classification, white blood cell count, hemoglobin and so on. The overall survival rate of high lncRNA-MALAT1 expression group was significantly lower than that of low expression group (χ
CONCLUSION:The up-regulated expression of lncRNA-MALAT1 is closely related to the clinical characteristics and survival rate, and is an independent prognostic factor for AML sepsis patients. LncRNA-MALAT1 is expected to become a new diagnostic marker and therapeutic target for AML sepsis.
