Studies suggest that astrocytes and microglia in the spinal cord are involved in the development of persistent pain induced by tissue inflammation and nerve injury. However, the role of glial cells in bone cancer pain is not well understood. The present study evaluated the spinal glial activation in a novel rat model of bone cancer pain produced by(More)
Although it has been shown that pro-inflammatory cytokines such as interleukin-1beta (IL-1beta) facilitate perception of noxious inputs at the spinal level, the mechanisms have not been understood. This study determined the cell type that produces IL-1beta, the co-localization of IL-1 receptor type I (IL-1RI) and Fos and NR1 in the spinal cord, and the(More)
In our previous studies using human LNCaP xenografts and TRAMP (transgenic adenocarcinoma of mouse prostate) mice, androgen deprivation therapy (ADT) resulted in a temporary cessation of prostate cancer (PCa) growth, but then tumors grew faster with more malignant behaviour. To understand whether cancer stem cells might play a role in PCa progression in(More)
Cancer pain impairs the quality of life of cancer patients, but opioid intervention can cause significant side effects that further decrease quality of life. Although electroacupuncture (EA) has been used to treat cancer pain, its mechanisms are largely unknown. To examine its effects and underlying mechanisms on cancer pain, we injected AT-3.1 prostate(More)
BACKGROUND Although pain affects the quality of life of cancer patients, current medical treatments are either ineffective or have side effects. In the present study we investigated the effect of electroacupuncture (EA) on cancer-induced hyperalgesia and expression of interleukin-1beta (IL-1beta), upregulation of which is related to the maintenance of(More)
PURPOSE Colorectal cancer is a major cause of death worldwide. To reduce the incidence and mortality from rectal cancer, an individual quantitative risk-assessment model (hereafter referred to as the Attributive Degree Value) and reverse passive hemagglutination fecal occult blood test were used in a randomized, controlled, population-based trial that was(More)
BACKGROUND To determine the feasibility and significance of lymphatic mapping and sentinel lymph node biopsy (SLNB) in patients with gastric cancer. METHODS From August 1999 to January 2002, 27 gastric cancer patients underwent lymphatic mapping and sentinel lymph node biopsy using isosulfan blue dye. RESULTS The success rate of SLNB was 96.3% (26 of(More)
Our previous study showed that electroacupuncture (EA) significantly attenuated inflammatory hyperalgesia. It has also been reported that EA analgesia in uninjured animals is mediated by mu and delta opioid receptors at 2-15 Hz and by kappa opioid receptor at 100 Hz. Because persistent pain changes neural response to external stimulation, we hypothesized(More)
Multidrug resistance (MDR) to chemotherapy is a significant barrier to the effective treatment of chromic myeloid leukemia (CML). In an attempt to identify more factors associated with MDR for an understanding of the mechanism, we first established an adriamycin (ADR)-resistant human erythroleukemia cell line K562/ADR by stepwise selection in vitro using(More)
BACKGROUND Acupuncture has traditionally been used in China and is being increasingly applied in Western countries to treat a variety of conditions, including inflammatory disease. However, clinical trials investigating the effectiveness of the anti-inflammatory effects of acupuncture have yielded inconsistent results, and the underlying mechanisms of(More)
