CD147 or EMMPRIN is a member of the immunoglobulin superfamily in humans. It is widely expressed in human tumors and plays a central role in the progression of many cancers by stimulating the secretion of matrix metalloproteinases (MMPs) and cytokines. CD147 regulates cell proliferation, apoptosis, and tumor cell migration, metastasis and differentiation,(More)
BACKGROUND Ventilator-associated event (VAE) is a new surveillance paradigm for monitoring complications in mechanically ventilated patients in intensive care units (ICUs). The National Healthcare Safety Network replaced traditional ventilator-associated pneumonia (VAP) surveillance with VAE surveillance in 2013. The objective of this study was to assess(More)
HER2, a ligand-free tyrosine kinase receptor of the HER family, is frequently overexpressed in breast cancer. The anti-HER2 antibody trastuzumab has shown significant clinical benefits in metastatic breast cancer; however, resistance to trastuzumab is common. The development of monoclonal antibodies that have complementary mechanisms of action results in a(More)
The current study aimed to examine the effects and underlying mechanisms of chronic psychological stress on the growth of ovarian carcinoma. Human ovarian carcinoma cells SKOV-3 were subcutaneously inoculated into nude mice to establish an ectopic mouse model. The animals were experimentally stressed 6 h daily for a total of 42 days with a physical(More)
Trastuzumab is widely used in the clinical treatment of human epidermal growth factor receptor-2 (HER2)-positive breast cancer, but the patient response rate is low. CD147 stimulates cancer cell proliferation, migration, metastasis and differentiation and is involved in chemoresistance in many types of cancer cells. Whether CD147 alters the effect of(More)
The binding of programmed death 1 (PD-1) to its ligands PD-L1 and PD-L2 on antigen-presenting cells has been proven to turn off autoreactive T cells and induce peripheral tolerance. In this study, fusion proteins linking the extracellular domains of murine PD-1, PD-L1 and PD-L2 to the Fc portion of a mouse immunoglobulin G2a monoclonal antibody were(More)
For many years, the question of whether hyperglycaemia, a manifestation of prediabetes, diabetes mellitus and metabolic syndrome, is a risk factor for colorectal cancer has been intensely studied. In fact, even after the conclusion of several prospective studies, the topic is still controversial. We conducted a systematic review and meta-analysis to(More)
We propose and experimentally demonstrate a method for fault location in optical communication network. This method utilizes the traffic signal transmitted across the network as probe signal, and then locates the fault by correlation technique. Compared with conventional techniques, our method has a simple structure and low operation expenditure, because no(More)
OBJECTIVE To clone anti-human death receptor 5 (DR5) single-chain variable fragments (scFvs) from a large natural phage antibody library and identify the antigen-binding activity. METHODS Phage antibodies against human DR5 were screened from a large natural phage antibody library constructed in our laboratory by four rounds of panning process using(More)
Crataegus sanguinea is a wild plant, which has been widely grown in the north and south of the Tianshan mountains in Xinjiang. In order to explore their anti-cancer properties, edible wild plants from Xinjiang have been tested for their antitumor properties. We used Ames tests, mouse bone marrow polychromatic erythrocytes micronucleus tests, and tumor cells(More)
