Abstract
BACKGROUND To contribute to evidence-based policy decision making for national cancer control, we conducted a systematic assessment to estimate the current burden of cancer attributable to known preventable risk factors in Japan in 2005. METHODS We first estimated the population attributable fractions (PAFs) of each cancer attributable to known risk factors from relative risks derived primarily from Japanese pooled analyses and large-scale cohort studies and the prevalence of exposure in the period around 1990. Using nationwide vital statistics records and incidence estimates, we then estimated the attributable cancer incidence and mortality in 2005. RESULTS In 2005, ≈ 55% of cancer among men was attributable to preventable risk factors in Japan. The corresponding figure was lower among women, but preventable risk factors still accounted for nearly 30% of cancer. In men, tobacco smoking had the highest PAF (30% for incidence and 35% for mortality, respectively) followed by infectious agents (23% and 23%). In women, in contrast, infectious agents had the highest PAF (18% and 19% for incidence and mortality, respectively) followed by tobacco smoking (6% and 8%). CONCLUSIONS In Japan, tobacco smoking and infections are major causes of cancer. Further control of these factors will contribute to substantial reductions in cancer incidence and mortality in Japan.

Abstract
BACKGROUND Previous studies have shown that anti-GQ1b antibodies induce massive neuromuscular blocking. If anti-GM1 and -GD1a antibodies have similar effects on the neuromuscular junction (NMJ) in human limb muscles, this may explain selective motor involvement in axonal Guillain--Barré syndrome (GBS). METHODS Axonal-stimulating single-fibre electromyography was performed in the extensor digitorum communis muscle of 23 patients with GBS, including 13 with the axonal form whose sera had a high titre of serum IgG anti-GM1 or -GD1a antibodies. RESULTS All patients with axonal or demyelinating GBS showed normal or near-normal jitter, and no blocking. CONCLUSION In both axonal and demyelinating GBS, neuromuscular transmission is not impaired. Our results failed to support the hypothesis that anti-GM1 or -GD1a antibody affects the NMJ. In GBS, impulse transmission is presumably impaired in the motor nerve terminal axons proximal to the NMJ.

Abstract
OBJECTIVES To study the utility of muscle ultrasound (US) for detection of fasciculations and its contribution to diagnosis in amyotrophic lateral sclerosis (ALS). Fasciculations are characteristic features of ALS, and US can detect them easily and reliably. New diagnostic criteria for ALS, the Awaji algorithm, reintroduced fasciculations as evidence of acute denervation equivalent to that of fibrillations and positive sharp waves. METHODS In 81 consecutive patients with sporadic ALS, we prospectively performed needle EMG and US in 6 muscles (tongue, biceps brachii, first dorsalis interosseous, paraspinalis, vastus lateralis, and tibialis anterior), and diagnostic category were determined by revised El Escorial criteria and Awaji criteria. RESULTS Fasciculations were much more frequently detected by US than by EMG in the tongue (60% vs 0%), biceps brachii (88% vs 60%), and tibialis anterior muscles (83% vs 45%). The proportion of the patients with definite or probable ALS was 48% by revised El Escorial criteria and 79% by Awaji criteria using US. CONCLUSIONS Muscle US is a practical and efficient tool to detect fasciculations, particularly in the tongue. A combination of US and EMG substantially increases the diagnostic sensitivity of ALS.

Abstract
POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes) syndrome is a rare cause of demyelinating neuropathy with monoclonal plasma cell proliferation, and POEMS neuropathy is usually chronically progressive. Herein, the authors report a 34-year-old woman with POEMS syndrome presenting as acute polyneuropathy. Within 2 weeks of disease onset, she became unable to walk with electrodiagnostic features of demyelination and was initially diagnosed as having Guillan-Barré syndrome. Other systemic features (oedema and skin changes) developed later, and an elevated serum level of vascular endothelial growth factor led to the diagnosis of POEMS syndrome. She received high-dose chemotherapy with autologous peripheral blood stem cell transplantation, resulting in good recovery. The authors also reviewed patterns and speed of progression of neuropathy in the 30 patients with POEMS syndrome; 22 (73%) of them were unable to walk independently with the median period of 9.5 months from POEMS onset (range 0.5-51 months). Whereas the speed of neuropathy progression varies considerably among patients, some POEMS patients can show acute or subacute polyneuropathy. The early diagnosis and treatment could result in rapid improvement as shown in the present patient.

Abstract
We investigated the effectiveness of chemoradiotherapy for the treatment of lymph node recurrence and hematogenous metastasis after esophagectomy for esophageal squamous cell carcinoma. Between 2001 and 2006, 216 patients with thoracic esophageal squamous cell carcinoma had curative esophagectomy. Of those, 23 with lymph node recurrence received chemoradiotherapy (50.0-68.8 Gy). In addition, five patients had isolated recurrences in a distant organ and received chemoradiotherapy (50.0-60.0 Gy). We analyzed outcomes from the radiotherapy for recurrent esophageal cancer. The 1-, 2-, and 5-year survival rates after recurrence for the 23 patients whose lymph node recurrence was treated with chemoradiotherapy were 52, 31, and 24%, respectively, and the median survival time was 13 months. Among the five patients with recurrent tumors in a distant organ, chemoradiotherapy produced a complete response in two patients, a partial response in one patient, and stable disease in two patients, giving an effectiveness rate of 60% (complete response + partial response). Chemoradiotherapy has a beneficial prognostic effect in patients with lymph node recurrence of esophageal squamous cell carcinoma. Chemoradiotherapy for a metastatic tumor in a distant organ may be the treatment of choice in cases where systemic chemotherapy has proven ineffective.

Abstract
ABSTRACTThe formation of paramagnetic centers upon γ-irradiation was examined for the silica based waveguides doped with P2O5 by using ESR and optical absorption. The centers inherent in SiO2 glasses such as Si-E′ and OHC were found to be replaced with P-related centers such as phosphorus oxygen hole centers and phosphorus electron center by introducing a small amount of P2O5. New type of POHC was detected especially in the glass with [P2O5] of 1.3 mol % at 77K, which was assumed to be a precursor of the POHC stable at room temperature. The correlation between γ-induced loss-increase and the formation of these defects was examined.

Abstract
Na(+),K(+)-ATPase is a housekeeping pump in virtually all animal cells. Recently, cardiac glycosides that inhibit Na(+),K(+)-ATPase have been reported to be candidate for novel anticancer drug. Here, we investigated clinical significance of Na(+),K(+)-ATPase alpha1-isoform (alpha 1NaK), alpha2-isoform (alpha 2NaK) and alpha 3-isoform (alpha 3NaK) in hepatocellular carcinoma (HCC). Interestingly, the expression levels of alpha 3NaK protein in HCC tissues were significantly higher than those in the accompanying non-tumor tissues, whereas no significant increases in expression of alpha 1NaK and alpha 2NaK proteins were observed in HCC compared to non-tumor tissues. The ouabain (10 microM)-sensitive K(+)-ATPase activities (Na(+),K(+)-ATPase activities) in the membrane fraction from HCC tissue were significantly higher than those from non-tumor tissues. The Na(+),K(+)-ATPase activity was positively and significantly correlated with the expression level of alpha 3NaK. Apparent affinity for Na(+) in the Na(+),K(+)-ATPase activity in HCC tissues was significantly lower than that in non-tumor tissues, consistent with an elevated expression of alpha 3NaK relative to alpha 1NaK. Our results suggest that overexpression of alpha 3NaK increases the Na(+),K(+)-ATPase activity of HCC cells.

Abstract
Phagocytosis is an initial step in innate immunity, which is also stimulated by signals via Toll-like receptors (TLRs); however, the cooperation of phagocytosis with signals through TLRs to establish acquired immunity is unknown. We found that phagocytosis is an essential process to induce an immune reaction against an insoluble TLR ligand. Cell-wall skeleton prepared from Mycobacterium bovis BCG (BCG-CWS), an insoluble TLR2 ligand, activated and matured murine splenic dendritic cell (DC) line BC-1 as well as a soluble TLR2 ligand, Pam3CSK4. Surprisingly, BC-1 maturation with BCG-CWS was completely suppressed by inhibiting phagocytosis, while that with Pam3CSK4 was not affected. Moreover, BCGCWS induced intense delayed-type hypersensitivity (DTH) reactions against mitomycin C-inactivated Lewis lung carcinoma cells but Pam3CSK4 did not. These results suggested that the phagocytosis process enables the insoluble TLR2 ligand to activate DCs via TLR2 comparable to a soluble TLR2 ligand in vitro, and stimulating TLR2 alone is not sufficient to establish T cell-mediated immunity in vivo. It is therefore conceivable that the process of phagocytosis induces additional effects on TLR2-stimulated DCs to activate cellmediated immunity in vivo.
