Screening of prognostic risk microRNAs for acute myeloid leukemia.

Objectives This study aimed to investigate the risk miRNAs (microRNAs) for AML (acute myeloid leukemia) prognosis and related regulatory mechanisms. Methods MiRNA and gene expression data, as well as clinical data of 176 patients were first downloaded from TCGA. Then miRNAs and genes significantly affecting the survival time based on KM survival curve were identified using Log Rank test.

Clinical study of pai-neng-da capsule in the treatment of chronic aplastic anemia.

Objective: To evaluate the efficacy and safety of Pai-Neng-Da Capsule (panaxadiol saponins component, PND), a new Chinese patent medicine, on patients with chronic aplastic anemia (CAA) and to explore the optimal therapeutic regimen for CAA.

Method: A total of 36 patients with CAA were enrolled and divided into three groups: the AP group (20 cases, andriol 120 mg/day + PND 240 mg/day), the ACP group (13 cases, andriol 120 mg/day + cyclosporine 3-6 mg kd(-1) day(-1) + PND 240 mg/day), and the PND group (3 cases, PND 240 mg/day). All patients were treated and followed up for 6 months.

Identification of key genes affecting disease free survival time of pediatric acute lymphoblastic leukemia based on bioinformatic analysis.

The poor prognosis of pediatric acute lymphoblastic leukemia (ALL) indicates the existence of key candidate genes that affect pediatric ALL and its prognosis. The limma package in R was applied to screen differentially expressed genes (DEGs), and the Survival package and KMsurv package in R were used to screen disease free survival time related genes (prognosis genes). Then, based on latent pathway identification analysis (LPIA), latent pathways were identified, and pathway-pathway interaction network was constructed and visualized by Cytoscape.

Antisense oligodeoxynucleotide against tissue factor inhibits human umbilical vein endothelial cells injury induced by anoxia-reoxygenation.

Aims: The role of antisense oligodeoxynucleotide against tissue factor (aODN/TF) in cultured human umbilical vein endothelial cells (HUVECs) subjected to anoxia-reoxygenation (A/R) was investigated.

Methods: HUVECs were divided randomly into control group, A/R group, aODN/TF+A/R group, sense oligodeoxynucleotide (sODN/TF) + A/R group and mismatched oligodeoxynucleotide (mODN/TF) + A/R group, in the latter 3 groups, HUVECs were transfected with aODN/TF, sODN/TF and mODN/TF respectively. HUVECs in all A/R groups underwent 3 hrs of anoxia and followed by 2 hrs of reoxygenation.

Stachydrine, a major constituent of the Chinese herb leonurus heterophyllus sweet, ameliorates human umbilical vein endothelial cells injury induced by anoxia-reoxygenation.

Stachydrine is a major constituent of Chinese herb leonurus heterophyllus sweet, which is used in clinics to promote blood circulation and dispel blood stasis. Our study aimed to investigate the role of stachydrine in human umbilical vein endothelial cells (HUVECs) injury induced by anoxia-reoxygenation. Cultured HUVECs were divided randomly into control group, anoxia-reoxygenation (A/R) group and 4 A/R+stachydrine groups.
