The preablation monocyte/ high density lipoprotein ratio predicts the late recurrence of paroxysmal atrial fibrillation after radiofrequency ablation.

Background: The monocyte/high-density lipoprotein ratio (MHR) has emerged as a promising alternative biomarker in the fields of cardiovascular disease and atrial fibrillation (AF). This retrospective study was aimed to explore the predictive value of the MHR for the late recurrence of AF after radiofrequency ablation.

Methods: From April 2015 to October 2018, patients with paroxysmal AF who had undergone radiofrequency catheter ablation at Subei People's Hospital of Jiangsu Province were enrolled in our study.

[Expression Changes of Serum Transferrin Receptor and Its Mechanism in Children with Acute Leukemia].

Objective: To investigate the expression changes of serum transferrin receptor（sTFR） and its related mechanism in children with acute leukemia（AL）.

Methods: Forty-six children with acute leukemia treated in our hospital from June 2016 to June 2017 were selected and enrolled in the AL group, 40 healthy children were enrolled in the control group. The related clinical data were recorded, including age, sex and CNSL level.

ONZIN Upregulation by Mutant p53 Contributes to Osteosarcoma Metastasis Through the CXCL5-MAPK Signaling Pathway.

Background/aims: Gain-of-function of mutant p53 is associated with a high rate of lung metastasis in osteosarcoma. To investigate the mechanism of mutant p53-induced osteosarcoma metastasis, expression array analysis was performed, comparing non-metastatic osteosarcomas from p53+/- mice with metastatic osteosarcomas from p53R172H/+ mice. Onzin (Plac8) was identified as one of the genes upregulated in p53R172H/+ mouse metastatic osteosarcomas.
