Osteosarcoma is a primary malignant tumor in adolescents, associated with high mortality and morbidity. The high-dose methotrexate (MTX) chemotherapy used to treat this disease may induce primary or secondary drug resistance, resulting in a reduced effect of comprehensive treatment. In this study, the relationship between reduced folate carrier (RFC) gene expression and intracellular drug ... more
In the struggle for life, the capacity of microorganisms to synthesize and secrete toxic compounds (inhibiting competitors) plays an important role in successful survival of these species. This ability must come together with the capability of being unaffected by these same compounds. Several mechanisms are thought to avoid the toxic effects. One of them is toxin extrusion from the ... more
This study aimed to analyze the spectrum and drug resistance of bacteria isolated from burn patients to provide a reference for rational clinical use of antibiotics. Up to 1914 bacterial strain specimens isolated from burn patients admitted to hospital between 2001 and 2010 were subjected to resistance monitoring by using the K-B paper disk method. Retrospective analysis was performed on ... more
We investigated the effect of autophagy on drug resistance of multiple myeloma (MM) to doxorubicin (DOX). A DOX-resistant MM cell line (RPMI8226/DOX) was developed by progressively increasing the DOX concentration gradient. The drug resistance index was determined using the MTT method. Transmission electron microscopy, anti-light chain 3-fluorescein isothiocyanate immunofluorescence, and ... more
Single nucleotide polymorphisms at codons 167, 198, and 200 in the β-tubulin isotype 1 gene have been associated with benzimidazole resistance. Until now, the only mutation observed in Ancylostoma caninum was at codon 200 of this gene. However, the standardized methodologies used to detect mutations in this species are faulty. The objective of this study was to standardize a ... more
Interkeukin-8 (IL-8) is an important inflammatory mediator. It is an angiogenic factor associated with inflammation and carcinogenesis. To date, research on IL-8 has been limited to its role as an indicator of inflammation. There has been no systematic research concerning IL-8 expression levels in the mouse mammary gland during pregnancy and lactation. Mouse mammary gland samples were ... more
The aim of this study was to investigate the role of cytokine genes in the susceptibility to Candida infection. A total of 275 consecutive patients diagnosed with Candida infection were selected between May 2010 and May 2011, along with 305 uninfected controls. Genotyping of the IL-1β gene polymorphisms (IL1β) rs1143634, IL1βrs16944 ... more
This case-control study aimed to investigate the role of -251 T>A (rs4073) and -781 C>T (rs2227306) polymorphisms in the interleukin-8 (IL-8) gene in the development of glioma in a Chinese population. One hundred and twenty-seven glioma patients and 284 healthy control subjects were recruited to this study between February 2013 and December 2014. The IL-8 -251 T ... more
In this study, we investigated the role of two single nucleotide polymorphisms in the promoter region of the interleukin-8 gene (IL-8; rs4073 and rs2227306) in the susceptibility to primary gouty arthritis in a Chinese population. Three hundred and twelve patients with primary gouty arthritis and 340 healthy controls were recruited from the Yan’an ... more
Early recovery of myocardial perfusion is beneficial for myocardial ischemia. However, ischemia-reperfusion (I/R) may exacerbate myocardial injury. Research shows that total peony glucoside (TPG) can inhibit ischemic myocardial cell apoptosis. However, whether it can ameliorate I/R injury remains poorly understood. This study explored the effect of TPG pretreatment ... more
