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.

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.

Objective:To evaluate of the feasibility of low-dose CT(LDCT)in the reconstruction of three-dimensional(3D)model of maxillofacial hard and soft tissues.Methods:Lightspeed 16-slice spiral CT scanner was used to scan one adult cadaveric head specimens with conventional parameters(280 mA)and low dose parameters(200,150,100,50,35,25,15 and 5 mA)respectively;the 3D model of the hard and soft tissues were reconstructed with Mimics 10.01 software,and 3D comparison were carried on with Geomagic 11.0 software.A comparison of the surface morphology of the hard and soft tissues of the 3D models with different scanning parameters was made.Results:With the reduction of the tube current,the model surface became rough gradually.Compared with the 280 mA scan results,the model surface produced by 35 mA scanning was still fairing,when the dose fell to less than 25 mA,the model surface became rough and the exact shape of the model could not be recognized.The same results of model surface were pro-duced after registration.Conclusion:The low-dose (35 mA)CT can be used to reconstruct 3D model of the maxillofacial hard and soft tissues.

"The Expert Group on Tumor Ablation Therapy of Chinese Medical Doctor Association, The Tumor Ablation Committee of Chinese College of Interventionalists, The Society of Tumor Ablation Therapy of Chinese Anti-Cancer Association and The Ablation Expert Committee of the Chinese Society of Clinical Oncology" have organized multidisciplinary experts to formulate the consensus for thermal ablation of pulmonary subsolid nodules or ground-glass nodule (GGN). The expert consensus reviews current literatures and provides clinical practices for thermal ablation of GGN. The main contents include: (1) clinical evaluation of GGN, (2) procedures, indications, contraindications, outcomes evaluation and related complications of thermal ablation for GGN and (3) future development directions.
