Diagnostic Value of ER, PR, FR and HER-2-Targeted Molecular Probes for Magnetic Resonance Imaging in Patients with Breast Cancer.

Background/aims: Smart molecular probes are required in the application of Magnetic resonance imaging (MRI) for biochemical and clinical research. This study aims to investigate the diagnostic values of estrogen receptor (ER), progesterone receptor (PR), folate receptor (FR) and human epidermal growth factor receptor 2 (HER-2)-targeted molecular probes in the MRI diagnosis of breast cancer.

Methods: Initially, a total of 508 female breast cancer patients were selected for breast cancer subtype classification by immunohistochemistry.

Biocompatible composite nanoparticles with large longitudinal relaxivity for targeted imaging and early diagnosis of cancer.

Early diagnosis of cancer greatly increases the chances of successful treatment by radical resection. The sensitivity of magnetic resonance imaging (MRI) techniques for detecting early stage tumors can be increased with the assistance of a positive MRI contrast agent. However, the traditional positive MRI contrast agents, such as Gd-chelates and Gd-based inorganic nanoparticles, are often limited by their cytotoxicity and low specificity.

Anti-tumor effects of dihydroartemisinin on human osteosarcoma.

Dihydroartemisinin (DHA) exhibits antitumor activity against a wide spectrum of cancer cells. However, whether DHA has anti-tumor effect on human osteosarcoma cells remains unknown. This study aims to investigate the anti-tumor activity of DHA and the underlying mechanisms in human osteosarcoma cell lines with different p53 mutation statuses.

Respiratory syncytial virus infection and risk of acute myocardial infarction.

Introduction: Increasing evidences have shown that pathogens may promote atherosclerosis and trigger acute myocardial infarction (AMI). There is no report on the association between respiratory syncytial virus (RSV) infection and AMI. The case-control study was used to assess the association of previous RSV infection and acute myocardial infarction.

[Expression of co-stimulatory molecules and role of interleukin 18 in peripheral lymphocytes of patients with idiopathic thrombocytopenic purpura].

The objective of study was to investigate the expressions of CD80, CD86 and its ligand CD28 on peripheral lymphocytes in patients with idiopathic thrombocytopenic purpura (ITP), to explore the effect of interleukin 18 (IL-18) and its clinical significance in ITP. The expressions of co-stimulatory molecules (CD80, CD86 and its ligand CD28) on peripheral lymphocytes from 34 ITP patients and 34 normal humans were detected by immunofluorescence and flow cytometry. The IL-18 in the plasma was detected by using enzyme linked immunosorbent assay (ELISA).
