Regulation Effect of Myeloid Leukemia No.1 Chinese Herb Medicine Prescription Combined with Chemotherapy on Th17 Cells in Bone Marrow of Patients with Acute Myeloid Leukemia / 中国实验血液学杂志

OBJECTIVE@#To explore the regulation effect of myeloid leukemia No.1 Chinese herb medicine prescription combined with chemotherapy on Th17 cells in bone marrow fluid of AML patients, so as to provide guidance for improving AML treatment effect and patients' long-term survival.@*METHODS@#Seventy patients with AML who were hospitalized in Department of Hematology, Wuwei People's Hospital from April 2017 to August 2019 were selected and enrolled in AML group, 25 healthy volunteers were selected and enrolled in control group; then according to therapeutic regimen, AML patients were divided into 2 groups: combined therapy group (myeloid leukemia NO.1 Chinese herb medicine prescription combined with chemotherapy) and non-combined therapy group (chemotherapy alone). Flow cytometry was used to detect the ratio of CD3@*RESULTS@#The ratio of CD3@*CONCLUSION@#Th17 cells expression in bone marrow of newly diagnoses and relapsed AML patients significantly increase, and decrease significantly after treatment. Myeloid leukemia No.1 Chinese herb prescription combined with chemotherapy can significantly increase the CR rate and reduce the RL rate for AML.

High Expression of Bone Marrow VEGF in Patients with Acute Leukemia and Its Correlation with Prognosis / 中国实验血液学杂志

OBJECTIVE@#To detect the level of vascular endothelial growth factor (VEGF) in bone marrow of patients with non-M3 acute leukemia (AL), and estimate its relationship with prognosis.@*METHODS@#From January 2016 to December 2019, 114 patients with AL in department of Hematology, Wuwei People's Hospital were selected as study group, and 25 healthy volunteers were enrolled as control group. The concentration of VEGF in bone marrow was detected by ELISA. The patients were divided into high and low concentration group according to the level of VEGF. The overall survival (OS) and event-free survival (EFS) were compared among different groups.@*RESULTS@#The level of VEGF in patients with AL was significantly higher than that in the control group. The median OS and EFS in the low concentration group was 34.5 and 32 months, respectively, while, in the high concentration group was 30 and 26 months, respectively. The differences between the two groups were statistically significant (P=0.010). There were significant differences in OS rate (P=0.035) and EFS rate (P=0.026) between low and high concentration group. Multivariate analysis showed that high VEGF concentration was an independent risk factor affecting OS (HR=2.619, 95%CI 1.070-6.406, P=0.035) and EFS (HR=2.221, 95%CI 1.074-4.552, P=0.031) in AL patients.@*CONCLUSION@#VEGF highly expresses in the bone marrow of patients with AL at initial diagnosis and relapse, and shows adverse effects on the prognosis.
