Circular RNA Pum_0014 Targets miR-146a-5p/NF2 Axis to Regulate VEGF/PAK1 Pathway and Reduce H2O2-induced Cardiomyocyte Apoptosis.

Circular RNAs (circRNAs) have emerged as essential regulators in cardiovascular disease, including acute myocardial infarction (AMI). This study investigated the role of circRNA Pum1_0014 in myocardial infarction (MI) and its underlying mechanisms using an H9C2 cell model. Through Sanger sequencing, nucleic acid electrophoresis, RNase R, and transcriptional inhibition experiments, Pum1_0014 was identified as a novel circRNA.

Levels of interleukin-35 and its relationship with regulatory T-cells in chronic hepatitis B patients.

Interleukin-35 is a novel inhibition cytokine secreted by CD4+CD25+ regulatory T-cells (Treg) in murine. However, it is disputed whether IL-35 could be secreted by Treg cells in humans. In this study, the levels of IL-35 were detected, and its relationship with regulatory T-cells in chronic hepatitis B (CHB) patients was investigated.

[A method of object detection for remote sensing-imagery based on spectral space transformation].

Object detection is an intermediate link for remote sensing image processing, which is an important guarantee of remote sensing application and services aspects. In view of the characteristics of remotely sensed imagery in frequency domain, a novel object detection algorithm based on spectral space transformation was proposed in the present paper. Firstly, the Fourier transformation method was applied to transform the image in spatial domain into frequency domain.

[Comparison of green coffee beans volatiles chemical composition of Hainan main area].

Chemical component of Hainan green coffee beans was analyzed with solid phase microextraction-gas chromatography-mass spectrometry, and the discrepancy between two green coffee beans was differentiated through the spectrum database retrieval and retention index of compound characterization. The experimental results show that: the chemical composition of Wanning coffee beans and Chengmai coffee beans is basically the same. The quantity of analyzed compound in Wanning area coffee is 91, and in Chengmai area coffee is 106, the quantity of the same compound is 66, and the percent of the same component is 75.

[Changes of serum hepatocyte growth factor before and after percutaneous coronary intervention in patients with unstable angina pectoris and significance there].

Objective: To investigate the effect of unfitrate heparin (UFH) and low molecular weight heparin (LMWH) on the expression of serum hepatocyte growth factor (HGF) during percutaneous coronary intervention (PCI).

Methods: Seventy patients with chronic unstable angina pectoris were divided into 2 groups: PCI group (n = 49, with at least one main coronary artery branch with stenosis > or = 70%) and non-PCI group (n = 21, with the main coronary artery branch with stenosis < 70%). UFH was used at the beginning of coronary angiography in both groups and LMWH was used after PCI only in the PCI group.

[Study on the process for wastewater treatment in submerged rotating membrane bioreactor].

The process for wastewater treatment in submerged rotating membrane bioreactor (SRMBR) was studied. It was found that the effluent COD reduced to 20 mg/L after one day running when the influent COD varied from 160 mg/L to 368 mg/L. The equilibrium membrane flux increased rapidly with increasing rotation speed of membrane in the range of 0 to 25r/min.
