Abstract
Context Oral anti-diabetic drugs (OADs) are leading option for treatment of type 2 diabetes (T2D). However, availability of OADs are limited in the presence of renal impairment (RI). Objective In this study, we examined the efficacy of repaglinide, which is mainly metabolized and excreted via non-renal route, in patients with T2D and severe RI that consists mainly of chronic kidney disease (CKD) stage 4. Design Subjects and Methods This was an open label, single arm, interventional study by repaglinide monotherapy. The primary efficacy end point was HbA1c change from baseline to week 12. Results Repaglinide treatment significantly reduced HbA1c levels from 7.7 ± 0.7% to 6.1 ± 0.3% (p<0.001) in 9 patients with severe RI (mean estimated glomerular filtration rate was 26.4 ± 7.5 mL/min/1.73m2). Focusing on 4 patients who received DPP-4 inhibitor monotherapy at enrolment, switching to repaglinide also significantly improved HbA1c levels. No hypoglycemic symptoms or severe hypoglycemia was reported in patients who completed the period of 12 weeks. Conclusions We demonstrated the efficacy of repaglinide in patients with T2D and severe RI. In case that DPP-4 inhibitors are not enough to achieve targeted range of glycemic control, repaglinide is another good candidate.

Abstract
Abstract
Background
Immune checkpoint therapy only benefits a fraction of patients, thus huge efforts have been made to develop predictive biomarkers to identify those patients. Immune biomarkers like PD-L1 expression are extremely dynamic and the timing of evaluation, on primary or metastatic disease, may be critical. We have already shown that tumour-infiltrating lymphocytes (TILs) decrease during metastatic progression in triple-negative (TN) and human epidermal growth factor-2 positive (HER2+) breast cancers (Ogiya R, ASCO 2015), suggesting that mechanisms of immune escape contribute and favour the metastatic progression. In this work we aimed to characterize the modulation and changes of specific immune markers during the metastatic spread comparing paired samples from primary and recurrent breast cancers.
Methods
We retrospectively identified 25 patients with HER2+ (n = 14) and TN (n = 11) early breast cancer diagnosed between 1990 and 2009 at Tokai University Hospital, and who subsequently experienced a first regional or distant recurrence confirmed by tumour biopsy/resection. Haematoxylin and eosin-stained slides of these paired samples were evaluated for stromal TILs. Immunohistochemical staining was performed using primary antibodies against CD4, CD8, Foxp3, PD-L1, PD-L2, and HLA-class I.
Results
The sites of first recurrence was the skin (n = 7), brain (n = 6), lymph node (n = 4), lung (n = 3), bone (n = 2), and one of each of bone marrow, liver and muscle. Immunohistochemical evaluations could not be performed in 5 primary tumours and 2 recurrent tumours because of the small quantity of the specimens. The percentage of CD8+ T cells staining in the primary tumours was significantly higher (median 16%) than that in recurrent tumours (median 10%) (paired t-test, p = 0.008) Similarly, the percentage of CD4+ T cells staining in the primary tumours was significantly higher (median 40%) than that in recurrent tumours (median 25%) (p = 0.026). The percentage of Foxp3+ T cells was low (<10%) and similar in both primary and recurrent tumours (p = 0.16). PD-L1, PD-L2, and HLA class I antibody expression was not statistically different between primary and recurrent tumours, but conversions from positive to negative and vice versa were observed. PD-L1+ staining (≥1%) was 90% and 85% in primary and metastatic tumours, respectively.

Conclusions
Tumours at first metastatic recurrence in HER2+ and TN breast cancers have a lower percentage of both CD8+ and CD4+ T cells compared to primary tumours, confirming a potential role of immune escape in tumour progression. Other immune markers, including PD-L1, were not found to change significantly, but negative/positive conversions were observed. This suggest that an evaluation of disease at the time of immunotherapy administration might be more informative. These findings warrant larger confirmation studies.

Abstract
Abstract
Introduction
Axillary lymph node dissection is standard therapy for patients with positive-node breast cancer, and can be performed with an electrocautery scalpel and suture ligation in most cases. However, knot slipping can occur during suture ligation and this can spread thermal damage to peripheral tissues. The LigaSureTM Small Jaw vessel-sealing system was developed as an alternative to suture ligatures, staplers, and other energy-dependent devices for sealing blood and lymphatic vessels, but its use in axillary dissection for breast cancer is limited. We prospectively compared the duration until drain removal after surgery, total lymph fluid drainage volume, intraoperative blood loss, and incidence of complications after axillary dissections, between this device and conventional methods.
Methods
This prospective randomized study was conducted at the Department of Breast and Endocrine Surgery at Tokai University School of Medicine, Kanagawa, Japan, between October 2011 and March 2015. Major eligibility criteria included (1) pathologically confirmed breast cancer diagnosis, (2) age ≥20 and ≤80 years, and (3) a signed informed consent form. The primary endpoint was duration until drain removal after surgery. The secondary endpoints were total lymph fluid drainage volume, intraoperative blood loss, and incidence of postoperative surgical complications. We defined the criterion for drain removal as a lymph fluid drainage volume of <40 mL/day for two consecutive days.The target accrual was 100 patients, with a two-sided error rate of 5%, and 90% power. The assumed duration until drain removal after surgery was 7.2 days in the control group (conventional use of an electrocautery scalpel and suture ligation) and 5.8 days in the study group (use of the LigaSureTM Small Jaw). This clinical study was approved by the Institutional Review Board of the Tokai University School of Medicine and is registered with UMIN (No. 000013034).
Results
Initially, 100 patients were assigned as eligible; however, two patients were later excluded because of the exclusion criteria. Of 98 patients, 49 were randomized to the study group, and 49 to the control group. The mean duration until drain removal after surgery was 5.2 days in the study group and 5.0 days in the control group (p=0.573). The mean total lymph fluid drainage volumes were 260.3 and 233.5 mL (p=0.502), and the mean intraoperative blood loss volumes were 17.8 and 18.0 mL (p=0.949), for the study and control groups, respectively. No significant differences were found between the two groups regarding drain removal duration, total drainage volume, and intraoperative blood loss volume. Both groups had low incidence rates of postoperative hematoma, wound infection, lymphedema, and pain, and had similar incidence rates of seroma formation after drain removal.
Conclusion
Our study results indicated that the use of the LigaSureTM Small Jaw in axillary dissection for breast cancer was as safe as conventional methods. However, using the LigaSureTM Small Jaw did not improve surgical outcomes such as duration until drain removal and total lymph fluid drainage volume compared with conventional methods.

Abstract
PURPOSE The purpose of this study was to assess the effects of recent surgical rib fixation and establish its indications not only for flail chest but also for multiple rib fractures. METHODS Between 2007 and 2015, 187 patients were diagnosed as having multiple rib fractures in our institution. After the propensity score matching was performed, ten patients who had performed surgical rib fixation and ten patients who had treated with non-operative management were included. Categorical variables were analyzed with Fischer's exact test and non-parametric numerical data were compared using the Mann-Whitney U test. Wilcoxon signed-rank test was performed for comparison of pre- and postoperative variables. All statistical data are presented as median (25-75 % interquartile range [IQR]) or number. RESULTS The surgically treated patients extubated significantly earlier than non-operative management patients (5.5 [1-8] vs 9 [7-12] days: p = 0.019). The duration of continuous intravenous narcotic agents infusion days (4.5 [3-6] vs 12 [9-14] days: p = 0.002) and the duration of intensive care unit stay (6.5 [3-9] vs 12 [8-14] days: p = 0.008) were also significantly shorter in surgically treated patients. Under the same ventilating conditions, the postoperative values of tidal volume and respiratory rate improved significantly compared to those values measured just before the surgery. The incidence of pneumonia as a complication was significantly higher in non-operative management group (p = 0.05). CONCLUSIONS From the viewpoints of early respiratory stabilization and intensive care unit disposition without any complications, surgical rib fixation is a sufficiently acceptable procedure not only for flail chest but also for repair of severe multiple rib fractures.

Abstract
BACKGROUND AND PURPOSE The champagne bottle neck sign represents a rapid reduction in the extracranial ICA diameters and is a characteristic feature of Moyamoya disease. However, the clinical significance of the champagne bottle neck sign is unclear. We investigated the relationship between the champagne bottle neck sign and the clinical and hemodynamic stages of Moyamoya disease. MATERIALS AND METHODS We analyzed 14 patients with Moyamoya disease before revascularization (5 men, 9 women; age, 43.2 ± 19.3 years). The ratio of the extracranial ICA and common carotid artery diameters was determined using carotid ultrasonography or cerebral angiography; a ratio of < 0.5 was considered champagne bottle neck sign-positive. The clinical disease stage was determined using the Suzuki angiographic grading system. CBF and cerebral vasoreactivity also were measured. RESULTS The ICA/common carotid artery ratio (expressed as median [interquartile range]) decreased as the clinical stage advanced (stages I-II, 0.71 [0.60-0.77]; stages III-IV, 0.49 [0.45-0.57]; stages V-VI, 0.38 [0.34-0.47]; P < .001). Lower ICA/common carotid artery ratio tended to occur in symptomatic versus asymptomatic arteries (0.47 [0.40-0.53] versus 0.57 [0.40-0.66], respectively; P = .06). Although the ICA/common carotid artery ratio was not related to cerebral perfusion, it decreased as cerebral vasoreactivity decreased (P < .01). All champagne bottle neck sign-positive arteries were classified as Suzuki stage ≥III, 73% were symptomatic, and 89% exhibited reduced cerebral vasoreactivity. In contrast, all champagne bottle neck sign-negative arteries were Suzuki stage ≤III, 67% were asymptomatic, and all showed preserved cerebral vasoreactivity. CONCLUSIONS The champagne bottle neck sign was related to advanced clinical stage, clinical symptoms, and impaired cerebral vasoreactivity. Thus, detection of the champagne bottle neck sign might be useful in determining the clinical and hemodynamic stages of Moyamoya disease.

Abstract
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.

Abstract
Abstract
In previous decades, numerous attempts have been made to develop therapeutic peptide vaccines for cancer. However, the HLA (Human Leukocyte Antigen) types are limited because most peptide vaccines are specific to the major HLA types of the area. Peptide vaccines specific for Caucasians thus may not be specific to Japanese. Moreover, they are not designed to stimulate both helper and killer T cells. We are trying to make a peptide vaccine specific to the MHC of Japanese patients that stimulates both helper and killer T cells. We selected a new-HER2 peptide including a B-cell epitope which has anti-tumor effects in a mouse system. The B-cell epitope was determined for a H401 monoclonal antibody (mAb) specific for HER2. As for epitope mapping of the chimera mAb CH401, enzyme-linked immunosorbent assay was employed with 20mer MAPs carrying a partial HER2 sequence. The CH401 epitope was determined as N:163-182, and the CH401MAP including the epitope induced anti-tumor effects in HER2-overexpressing tumor cells in a mouse system. We predicted the peptide MHC affinity and examined the in vitro reaction of PBMCs from Japanese breast cancer patients. The study enrolled 173 female breast cancer patients who underwent surgery between October 2010 and July 2012 at Tokai University Hospital. We used SYFPEITHI, BIMAS and IEDB algorithms to estimate peptide and HLA affinity. Lymphocyte proliferation ability, cell surface marker expression, cytokine (interleukin (IL)-2, IL-4 and interferon (IFN)-g) secretion and specific antibody production were analyzed in vitro. According to the algorithms, 97.1% of patients showed high to intermediate affinity of the CH401 epitope peptide to Japanese major HLA class I. Similarly, 34.5% of patients showed high to moderate affinity to HLA class II. The proliferative ability of patient groups was significantly higher than that of the HD group (HER2 0 group, p<0.05; HER2 1+2+ group, p<0.01; HER2 3+ group, p<0.01). Cell percentages of CD8+ cells were significantly increased after 21 days of CH401MAP stimulation. In the HER2 0 patient group, CD4+CD25+ cell ratio was also increased, while no significant increase was seen in the other groups. Foxp-3 expression was not increased in any groups, suggesting that these cells were not regulatory T cells. Concentrations of IL2 in stimulated supernatant tended to increase in all patient groups. In particular, concentration in the HER2 1+2+ group at 48 h was significantly increased (p<0.001). IL-4 and IFN-g secretion also tended to increase. CH401MAP-specific antibodies were measured for all breast cancer patient groups and HD, showing significant differences. However, within each patients’ group, no significant differences were observed irrespective of CH401MAP stimulation (p<0.001). As a result, reactivity with CH401MAP and breast cancer patient PBMCs activated immunity in the total breast cancer patient group, and the association with HER2 expression level of the primary cancer was poor overall. Collectively, CH401MAP may become a promising peptide vaccine to prevent recurrent breast cancer in Japanese patients.

Abstract
The purpose of this study was to determine the mortality rate in 527 critically ill patients with multiple organ failure (MOF), treated in our ICU between August, 1986 and January, 1992, and to compare it with the results obtained in a group of patients studied who had been treated between October, 1978 and July, 1986. The relationship between the mortality rate and each type of organ failure and the extent of organ system involvement was also investigated. The overall mortality rate was 25%, and the rate increased with the number of failed organs. Sepsis and disseminated intravascular coagulation were closely associated with the development of MOF. The mortality rate of patients with the failure of two organs in the present study was significantly lower than that found in those in the previous study. Although artificial organ mechanical life support technology other than that for patients with renal failure is still unsatisfactory, these results suggest that the prognosis of patients with MOF is improving.

Abstract
Abstract
Background: Bisphosphonate therapy has decreased the risk of skeletal complications associated with osteolytic bone lesions in patients with breast cancer and multiple myeloma. The large prospective studies have used 21 to 24 months of treatment. We studied the safety and efficacy of Zoledronic acid in a subset of patients who received therapy for more than 24 months.
Patients and Methods: Patients who received Zoledronic acid were identified. Data on skeletal events and laboratory parameters were gathered by chart review. The treatment regimen is 4 mg of Zolendronic acid at 3- to 4-week intervals, and concurrent chemotherapy, hormonal therapy, and radiation therapy was included. Before approval of Zoledronic acid, we were using Pamidronate and Incadronate.
Results: We used the Zoledronic acid in 221 patients from June 2006 until December 2011 (range, 1–69 times of administration). We analyzed 71 cases in which the treatment could be continued for more than 24 months (range, 24–69 times of administration). No significant calcium, phosphorus, electrolyte abnormalities were encountered. There were no significant differences between the long-term treatment patients with Zoledronic acid and all the other patients in the range of pain felt at the time of the bone metastasis diagnosis, or the bone metastases sites. In addition, by March 2012, more than 50% patients of long-term usage of Zoledronic acid had continued receiving treatment. And in all of the patients, as well, the most cited reason for discontinuing treatment was a disease progression, adverse effect was few. In long-term treatment patients, 4 cases of fractures and 2 cases of spinal compression were encountered. The median time until an SRE occurred was 37 months. There were fewer occurrences of SREs in our investigation than in the 12 months of a clinical trial conducted in Japan with Zoledronic acid and a placebo. As for adverse effects, BRONJ appeared in 4 (1.8%) out of a total of 221 cases, and in 3 (4.2%) at prolonged treatment patients. The other adverse effects were fever in 4 cases and fatigue in 2 cases.
Conclusion: Prolonged treatment with Zoledronic acid seems to be well tolerated and should be studied in prospective, randomized studies to document prolonged skeletal efficacy and survival.

Abstract
Five infants with cerebellar medulloblastoma, who all presented within the first year of life, are presented. The initial characteristic presenting symptoms included vomiting and macrocrania, frequently followed by a delay in normal development. No patients showed any signs or symptoms of cerebellar dysfunction. One infant, who was initially diagnosed as having a congenital hydrocephalus, died 4 months after undergoing a cerebrospinal fluid shunt operation, while the remaining four patients all underwent direct surgery for their tumors and three also received an additional course of postoperative radiation therapy. Of these four patients, three died within 4 years after diagnosis, with a mean survival period of 2.7 years, whereas one is still alive after a follow-up period of more than 20 years. However, the patient does suffer from both physical and intellectual handicaps. The clinical and histological features of infantile medulloblastomas are reviewed while the therapeutic problems associated with these tumors are also discussed.

Abstract
The gravitational-wave (GW) sky may include nearby pointlike sources as well as stochastic backgrounds. We perform two directional searches for persistent GWs using data from the LIGO S5 science run: one optimized for pointlike sources and one for arbitrary extended sources. Finding no evidence to support the detection of GWs, we present 90% confidence level (C.L.) upper-limit maps of GW strain power with typical values between 2-20×10(-50) strain(2) Hz(-1) and 5-35×10(-49) strain(2) Hz(-1) sr(-1) for pointlike and extended sources, respectively. The latter result is the first of its kind. We also set 90% C.L. limits on the narrow-band root-mean-square GW strain from interesting targets including Sco X-1, SN 1987A and the Galactic center as low as ≈7×10(-25) in the most sensitive frequency range near 160 Hz.

Abstract
BACKGROUND The pathogenesis of cerebrospinal fluid (CSF) hypovolemia is supposed to be caused by CSF leakage through small dural defects. PURPOSE To compare source three-dimensional (3D) fast spin-echo (FSE) images of magnetic resonance (MR) myelography with radionuclide cisternography findings, and to evaluate the feasibility of MR myelography in the detection of CSF leakage. MATERIAL AND METHODS A total of 67 patients who were clinically suspected of CSF hypovolemia underwent indium-111 radionuclide cisternography, and 27 of those who had direct findings of CSF leakage were selected for evaluation. MR myelography with 3D FSE sequences (TR/TE 6000/203 ms) was performed at the lumbar spine for all patients. We evaluated source images and maximum intensity projection (MIP) images of MR myelography, and the findings were correlated with radionuclide cisternography findings. MR myelography of five healthy volunteers was used as a reference. The MR visibility of the CSF leakage was graded as definite (leakage clearly visible), possible (leakage poorly seen), or absent (not shown). RESULTS CSF leakage was identified with source 3D FSE images in 22 (81.5%) of 27 patients. Of the 22 patients, 16 were graded as definite and six were graded as possible. For the definite cases, 3D FSE images clearly showed the extent of the leaked CSF in the paraspinal structures. In the remaining five patients with absent findings, radionuclide cisternography showed only slight radionuclide activity out of the arachnoid space. CONCLUSION Source 3D FSE images of MR myelography seem useful in the detection of CSF leakage. Invasive radionuclide cisternography may be reserved for equivocal cases only.

Abstract
Experiments were conducted to assess the degradability of 30 PPCPs, selected on the basis of consumption and environmental relevance, by O3 process, UV process and AOPs consisting of UV/ H2O2, O3/UV and O3/H2O2. A batch reactor with volume of 22L of water including the PPCPs was used. For UV process, combination of UV and H2O2 or O3 that can generate OH radicals was capable of degrading the PPCPs faster than UV radiation alone. On the other hand, O3 process and O3-based/UV-based AOPs could remove a variety of the PPCPs effectively, while some PPCPs such as 2-QCA, DEET and cyclophosphamide showed a relatively low degradability compared with the other PPCPs. However, further evaluation on formation of intermediate products resulting from the degradation of the parent PPCPs will be needed because DOC concentration was not decreased with lowered concentrations of the PPCPs.

Abstract
To evaluate the usefulness of computerized brain-surface dynamic voltage topography (DVT) of ictal electrocorticographic (ECoG) discharges to localize and identify epileptogenic areas, 3 patients with intractable frontal lobe epilepsy who underwent epilepsy surgery after chronic subdural electrode recording were assessed. Cortical surfaces and subdural electrodes were photographed during initial surgery to create an electrode map that could be superimposed onto a picture of the brain surface. DVT was performed by calculating sequential amplitudes of ictal ECoG discharges, which were then superimposed onto the cortical and electrode maps. In all cases, DVT clearly identified the ictal onset zone and the early propagation area on the operative field. DVT allowed recognition of spatial relationships between the epileptogenic area and structural abnormalities, functional cortex, and cortical veins; and was useful to decide on the resection area.

Abstract
Intrarenally synthesized angiotensin II (Ang II) may be involved in the progression of glomerulonephritis, leading to irreversible glomerulosclerosis. There is increasing evidence that systemic angiotensin receptor blocker (ARB) treatment has beneficial effect on the prognosis of progressive glomerulonephritis and diabetic nephropathy. However, the cellular and molecular mechanisms behind this therapeutic effect of ARB remain unclear. In this study, we used a novel strategy of local ARB delivery via type-1 collagen sponge, to treat progressive glomerulonephritis that would result in irreversible glomerulosclerosis in our previously established rat model. At days 9 and 14 after disease induction, mild proteinuria, 20.7+/-4.7 and 10+/-1.3 mg/day, was found. Local ARB treatment reduced proteinuria significantly to 3.19+/-3.2 and 5.25+/-0.95 mg/day (P < 0.01), respectively. Scoring of glomerular matrix expansion and sclerotic index revealed that local ARB treatment significantly ameliorated glomerular pathology. Ang II type 1 receptor mRNA expression was remarkably enhanced in the Ang II group and ARB treatment reversed this effect at 14 days. Local delivery of ARB significantly improved glomerular blood flow levels, compared to the untreated disease control group, from 710+/-18.25 to 859.44+/-22.86 microm/s, respectively. Local delivery of ARB into the kidney affected local RAS and thus improved the renal injury and function in the potentially progressive glomerulosclerosis of rat model.

Abstract
There is increasing evidence that changes of glomerular hemodynamics or glomerular growth responses may promote the development of glomerulosclerosis. Major problems retarding research progress include lack of suitable experimental animal models, with the exception of the ablation model, and the need for in vivo real-time analysis of glomerular hemodynamics. This study examined the sequence of pathological changes from the viewpoints of microcirculation and histopathology, from the acute stage to the chronic course and the final stage of glomerulosclerosis, using the confocal laser scanning microscope system. There is a marked difference in prognosis between sham-operated (two-kidney) and nephrectomized (one-kidney) rats after injection with anti-Thy-1 antibody. The former reversibly returns to normal and the latter irreversibly go to progressive sclerosis, respectively. The turning point determining the progression of glomerulosclerosis in both groups seemed to be the period from 7 to 14 days after disease induction, when disturbance of local intraglomerular blood flow continued in the one-kidney groups. In conclusion, this study provides the first hemodynamic-based evidence showing that disturbance of intraglomerular microcirculation is a critical marker for progressive glomerulosclerosis.

Abstract
PURPOSE The purpose of this study was to assess the pain relief in patients with unresectable and recurrent colorectal cancer treated with radiation plus 8 MHz radiofrequency-capacitive regional hyperthermia and to identify predictors of the good outcome. METHODS Between February 1986-May 2003, 41 patients with primarily unresectable and recurrent colorectal cancer that caused pain were treated with thermoradiotherapy at the hospital and retrospectively analysed. Radiotherapy was administered with a mean total radiation dose of 56 Gy. Hyperthermia was usually applied within 30 min after radiotherapy once or twice a week. For cooling of the skin surface, the overlay boluses were applied in addition to regular boluses. The external cooling unit has been used to reinforce the cooling ability of the overlay bolus and achieve strong surface cooling to reduce the preferential heating of the subcutaneous fat tissue and treat with more RF-output in 17 patients since January 1997. RESULTS Pain relief was obtained in 83% of the patients. Multi-variate analysis by logistic regression to evaluate the effects of certain factors on pain relief (complete response + good response) was strongly correlated with the presence of radiating pain to leg(s) (p < 0.05). The median follow-up was 18 months. The median duration of pain relief was 7.0 months. For the 27 patients in whom the tumour temperature was estimated, the median duration of pain relief was 14.6 months for the patients with a mean average tumour temperature of > 42.5 degrees C and 5.7 months for those of < 42.5 degrees C (p < 0.05). In the 18 patients with radiating pain to leg(s), use of strong superficial cooling and the higher numbers of hyperthermia treatments were better prognostic factors for the duration of pain relief (p < 0.01 and p < 0.05, respectively). CONCLUSIONS Radiotherapy with 8 MHz radiofrequency-capacitive regional hyperthermia provided an efficient, effective means on pain relief of treating unresectable and recurrent colorectal cancer. The duration of pain relief can be prolonged, if an adequate heating is achieved, especially in the patients with radiating pain to the leg(s).

Abstract
Mucin-depleted foci (MDF) are considered as useful biomarkers in rat colon carcinogenesis. The purpose of the present study was to examine the mechanism(s) underlying rat colon carcinogenesis induced by 1,2-dimethylhydrazine (DMH) plus 1% Dextran Sulfate Sodium (DSS). Twelve male F344 rats were given subcutaneous injections (40mg/kg body) of DMH twice a week. They received DSS in the drinking water for 1 week after the first injection of DMH and then were maintained on tap water. The rats were sacrificed at 10 and 14 weeks after the first injection of DMH. Colon tissues were divided into 10 segments from anus to cecum (A/J) and stained with Alcian blue (AB) to identify MDF. We found that MDF and tumors were induced in the rat colon after treatment with DMH plus DSS and that the number of MDF in each segment of the colon was significantly correlated with that of tumors (p=0.006). In addition, we found that the beta-catenin protein was accumulated in cytoplasm and nuclei of MDF and the frequent beta-catenin gene mutations in the colon tumors. These results suggest that MDF is closely related to rat colon carcinogenesis induced by DMH plus DSS.

Abstract
Bone marrow (BM) cells contribute to the maintenance and repair of several compartments of the kidney, including the endothelium, interstitium, epithelium, and the mesangium. The aim of this study was to explore the therapeutic use of bone marrow-derived cells (BMDC) that can differentiate into endothelial and mesangial cells in a model of progressive glomerulosclerosis. To investigate the involvement of BMDC in glomerular repair, progressive glomerulosclerosis was induced in enhanced green fluorescent protein BM chimeric rats by a one-shot injection of anti-Thy-1.1 monoclonal antibody, followed by unilateral nephrectomy. Subsequently, these rats were treated with either a BM cell infusion or phosphate-buffered saline. Renal function, intravital glomerular hemodynamics, and histological alterations were examined 12 weeks after anti-Thy-1.1 monoclonal antibody injection. Inflammatory infiltration of macrophages in the kidneys was evaluated by immunofluorescence of ED-1. We also determined whether BMDC contributed to repair and regeneration of endothelial and mesangial cells by immunofluorescence monitoring. As a result, BM cell infusion improved renal function and glomerular hemodynamics, and histological alterations with reduced glomerular infiltration of macrophages, leading to dramatically reduced mortality in this model of progressive glomerulosclerosis. We also demonstrated that, in the BM cell infusion group, more BMDC contributed to repair and regeneration of endothelial and mesangial cells than in the untreated group. The present study provides us with a conceptual basis for the development of therapeutic stem cell strategies aimed at enhancing recovery from progressive glomerulosclerosis.

Abstract
The modifying effects of dietary administration of an herb, Terminalia catappa (TC), were investigated on rat colon carcinogenesis induced by a carcinogen azoxymethane (AOM). The number of aberrant crypt foci (ACF) and beta-catenin accumulated crypts (BCACs) in the colon, and proliferating cell nuclear antigen (PCNA) labelling index in the colonic epithelium were examined in a total of 36 male F344 rats. All animals were randomly divided into five experimental groups (4-10 rats in each group). At 6 weeks of age, rats in groups 1, 2 and 3 were given s.c. injections of AOM once a week for 2 weeks at a concentration of 20 mg/kg body weight. One week before the first injection of AOM, rats in groups 2 and 3 were fed a diet containing 0.02 and 0.1% TC, respectively, throughout the experiment. Rats in group 4 were fed a diet containing 0.1% TC. Rats in group 5 were served as untreated controls. All animals were sacrificed at the experimental week 5 after the start of the experiment. Oral administration of TC at both doses significantly decreased the numbers of both ACF/colon/rat (P<0.05 for 0.02% TC, P<0.005 for 0.1% TC) and BCAC/cm/rat (P<0.05 for both 0.02 and 0.1% TC), when compared with the control group (group 1). Colonic PCNA labelling index in groups 2 and 3 was also significantly lower than that in group 1 (P<0.001 for 0.02% TC, P<0.005 for 0.1% TC). These results suggest that TC has a potent short-term chemopreventive effect on biomarkers of colon carcinogenesis and this effect may be associated with the inhibition of the development of ACF and BCACs.

Abstract
A 15-year-old girl developed intractable epilepsy following a right transcallosal resection of the intraventricular teratoma. Magnetic resonance (MR) imaging showed a T (2)-prolonged subcortical lesion in the right frontal lobe as well as a residual intraventricular tumor. The integration of the voltage topography of ictal onset activities of the scalp-recorded electroencephalogram (EEG) and a surface anatomy scan of MR images clearly revealed the epileptogenic area on the cortex above the subcortical lesion, with the propagation pattern towards the frontopolar area. Excision of the epileptogenic cortex and underlying gliosis resulted in a successful cessation of the epilepsy. This non-invasive EEG technique provided useful information that accurately localized the epileptogenic area on a large structural abnormality without invasive intracranial electrocorticographic monitoring.

Abstract
Twenty-five patients who required mechanical ventilatory support (MVS) after major surgery or severe burns were studied to determine whether airway occlusion pressure (P(0.1)) is a clinically useful indicator to predict the success or failure of the weaning trial. A total of 33 weaning trials were attempted on these patients. Of the 33 trials, 24 were followed by successful weaning and 9 by failure. Although the success group, when compared with the failure group, had a lower respiratory rate ( P << 0.001), a lower minute ventilation ( P << 0.001), a higher maximal voluntary ventilation to minute ventilation ratio ( P << 0.01) and a higher forced vital capacity ( P << 0.05), no threshold values separated the success from the failure group. The alveolar-arterial P(O)(2) gradient, with an F i(O)(2) of 1.0, in weaning success and failure showed no statistical difference. In contrast, all patients in the success group had a P(0.1) of less than 3.5 cmH(2)O and those in the failure group had a P(0.1) of greater than 3.5 cmH(2)O ( P << 0.001). We conclude that P(0.1) is a clinically superior indicator for discontinuing MVS in patients with acute respiratory failure.

Abstract
Patients with a large or massive tear of the rotator cuff were, when possible, treated with the McLaughlin procedure. A patch graft was used when it was impossible to perform this procedure. The patch group (group P) consisted of nine patients with nine shoulders (six men, three women) with a mean age of 62.8+/-6.9 years. The McLaughlin group (group M) consisted of 12 patients with 12 shoulders (ten men, two women) with a mean age of 52.3+/-8.6 years. Mean follow-up was 2 years 11 months in group P and 4 years 2 months in group M. Using the shoulder scoring system of the Japanese Orthopaedic Association (JOA score), the total score improved post-operatively in both groups. In group P, the post-operative score was 91.7 (pre-operative score 47.9) and in group M 92.0 (pre-operative score 54.2). Tears recurred in three shoulders within 2 months of the McLaughlin procedure, and these patients were excluded from the study. The rate of 're-tearing' was lower with a patch graft (0/13) than with the McLaughlin procedure (3/17).

Abstract
To evaluate the efficacy and toxicity of the sequential nonplatinum combination chemotherapy consisting of gemcitabine (GEM) and vinorelbine (VNR) followed by docetaxel (DOC) in patients with advanced non-small-cell lung cancer (NSCLC), we conducted the multiinstitutional phase II study. A total of 44 chemotherapy-naive patients with advanced NSCLC were treated with GEM 1000 mg m(-2) and VNR 25 mg m(-2) intravenously on days 1 and 8 every 3 weeks for three cycles. DOC 60 mg m(-2) was then administrated intravenously at 3-week intervals for three cycles. Patients were evaluated for response and toxicity with each cycle of the treatment. The major objective response rate was 47.7% (95% confidence interval (CI), 33.8-62.1%). Median survival time (MST) was 15.7 months and 1-year survival rate was 59%. In the GEM/VNR cycle, grade 3/4 neutropenia occurred in 36.3%, grade 3/4 anaemia in two patients (4.5%) and grade 3 thrombocytopenia in one patient (2.3%). Grade 3 pneumonitis occurred in two patients (4.5%) in GEM/VNR cycles. In the DOC cycles, grade 3/4 neutropenia occurred in 39.4% but no patient experienced grade 3/4 anaemia or thrombocytopenia. Of the 44 eligible patients, 33 patients completed three cycles of GEM/VNR and 22 patients completed six cycles of planned chemotherapy (three cycles of GEM/VNR followed by three cycles of DOC). The sequential triplet nonplatinum chemotherapy consisted of GEM/VNR followed by DOC, and was very active and well tolerated. This study forms the basis for an ongoing phase III trial that compares this nonplatinum triplet and standard platinum doublet combination (carboplatin/paclitaxel).

Abstract
To evaluate the usefulness and limitations of magneto-encephalography (MEG) for epilepsy surgery, we compared 'interictal' epileptic spike fields on MEG with ictal electrocorticography (ECoG) using invasive chronic subdural electrodes in a patient with intractable medial temporal lobe epilepsy (MTLE) associated with vitamin K deficiency intracerebral hemorrhage. A 19-year-old male with an 8-year history of refractory complex partial seizures, secondarily generalized, and right hemispheric atrophy and porencephaly in the right frontal lobe on MRI, was studied with MEG to define the interictal paroxysmal sources based on the single-dipole model. This was followed by invasive ECoG monitoring to delineate the epileptogenic zone. MEG demonstrated two paroxysmal foci, one each on the right lateral temporal and frontal lobes. Ictal ECoG recordings revealed an ictal onset zone on the right medial temporal lobe, which was different from that defined by MEG. Anterior temporal lobectomy with hippocampectomy was performed and the patient has been seizure free for two years. Our results indicate that interictal MEG does not always define the epileptogenic zone in patients with MTLE.

Abstract
BACKGROUND We describe an unusual lesion that represents an uncommon but important element in the differential diagnosis of subcutaneous scalp nodules in a child. CASE DESCRIPTION A 1-year-old boy presented with two clusters of subcutaneous scalp nodules. The lesions increased in size and number. Computed tomography showed no changes in underlying bone. Findings on magnetic resonance imaging were nonspecific. Serologic and clinical evaluation showed no evidence of rheumatic disease. Complete excision of the nodules, together with adjacent fascia and galea, was performed. Histopathologic examination showed the lesions to be palisading granulomas; given the absence of rheumatic disease, these represented deep granuloma annulare, a benign condition. No recurrence has been observed in our patient. CONCLUSION While we chose total excision because of preoperative concerns about a possible malignant tumor, some other authors have suggested that surgery be limited to confirmatory biopsy when a benign lesion such as palisading granuloma is strongly suspected.

Abstract
We investigated the expression of cell adhesion molecules on the surface of glomerular endothelial cells (GEC), dermal microvascular endothelial cells (MvE), and umbilical vein endothelial cells (HUVEC) that had or had not been stimulated by cytokines. PECAM-1 was constitutively expressed at a high level on HUVEC but its expression level decreased following stimulation by tumor necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma). PECAM-1 was also constitutively expressed on microvascular endothelial cells MvE and GEC, but at lower levels than on HUVEC, and expression by these cells also decreased in response to TNF-alpha and IFN-gamma. There was no dose-dependent effect on MvE but there was a dose-dependent effect on the level of expression of cell adhesion molecules on GEC. TNF-alpha induced the expression of VCAM-1 on HUVEC and GEC, but not MvE, while IFN-gamma induced VCAM-1 expression only on HUVEC. TNF-alpha induced the expression of E-selectin on all three kinds of endothelial cells, but IFN-gamma had no effect on E-selectin expression. GEC therefore showed expression patterns of PECAM-1, VCAM-1, and E-selectin different from those seen in HUVEC and MvE upon treatment with TNF-alpha or IFN-gamma. The use of cultured human GEC allows us to study not only the inflammatory processes, but also the pathophysiological role of GEC in hemodynamic disturbances and their interaction with intrinsic mesangial cells at the molecular and subcellular levels.

Abstract
We report 2 infants who were born as one of monochorial twins. Both of them had been suffering from twin-twin transfusion syndrome(TTTS) as a donor fetus. Case 1 was delivered by caesarean section at the 28th week of pregnancy. On day 0, intraventricular hemorrhage(IVH) occurred from the right subependymal germinal matrix layer, and progressive ventricular enlargement was followed. Case 2 was delivered by the caesarean section at the 31st week of pregnancy. On day 9, he developed IVH from the choroid plexus at the trigone of the left lateral ventricle, and progressive enlargement of the inferior and posterior horns, trigone and posterior part of the body of the left lateral ventricle was followed. IVH in patients with TTTS usually occur in recipient infant but it can also occur in donor infant as in our cases. Pathophysiology of central nervous system damages associated with TTTS is variable and complicated.

Abstract
To compare the neuroexcitatory effects of sevoflurane and isoflurane, we recorded electrocorticograms (ECoG) during wakefulness and during sevoflurane and isoflurane anesthesia in six patients with temporal lobe epilepsy (TLE). These patients had subdural grid electrodes chronically implanted in the temporal region. During sevoflurane anesthesia at 1.5 minimum alveolar concentration (MAC) of the combination with 67% nitrous oxide (N2O), a marked increase in interictal paroxysmal activities was observed in four patients. Two patients had a slight increase in paroxysmal activities. Activated areas were widely distributed, not being confined to the ictal onset zone of spontaneous seizures. However, isoflurane anesthesia at 1.5 MAC of the combination with 67% N2O was associated with less increased paroxysmal activity. While the neuroexcitatory properties of sevoflurane proved greater than those of isoflurane, the widespread irritative response to sevoflurane administration was not helpful in localizing the epileptogenic area.

Abstract
A 14-year-old female, who had intractable epilepsy associated with multiple focal cortical dysplasias (FCD), was reported. She developed intractable epilepsy at the age of 7 and was diagnosed as having frontal lobe epilepsy based on the seizure semiology and interictal EEG. MRI revealed multiple lesions in the right frontal, bilateral occipital and left parietal lobes. EEG demonstrated that ictal discharge was preceded by spike on the right frontal region and FDG-PET showed hypometabolic area in the right frontal lobe. Chronic subdural electrode recordings from the right frontal lobe indicated that ictal onset zone was located around the right frontal lesion, especially frontal tip and base, and these areas including the lesion were resected. Postoperatively, residual seizure was noted although seizure frequency was decreased. It is well known that, postoperatively, satisfactory seizure outcome can be obtained in patients with FCD. However, further investigation in terms of surgical indication and strategies for multiple FCD should be needed.

Abstract
In order to investigate the cytokine profile in toluene diisocyanate (TDI)-induced occupational asthma, we conducted a quantification of cytokine production in a murine model of respiratory hyperreactivity to TDI. Wistar rats were sensitized with intranasal application of 10% TDI and provoked with 5% TDI to induce airway hypersensitivity. The blood leucocytes were counted, and bronchoalveolar lavage (BAL) was performed and the cellular responses in BAL fluid were analysed. Lung histological examination was performed to investigate the inflammatory status in the airway. The production of IL-2, IL-4, IL-6 and IFN-gamma in serum, BAL fluid and spleen cell were determined with ELISA kits. The cellular results demonstrated that neutrophils and eosinophils in blood were significantly increased and the total cells and each different cell, in particular eosinophils in BAL fluid were markedly increased in TDI sensitized rats. Histological analysis showed that a respiratory inflammation represented by prominent infiltration of eosinophils in central and peripheral airways was present in TDI-sensitized rats. The cytokine assays revealed that in TDI-sensitized rats, IL-4 was predominately secreted in serum, and IL-4 and IL-6 rather than IL-2 and IFN-gamma were predominately secreted in BAL fluid and in spleen cell. These findings suggested that IL-4 and IL-6 are preferentially produced and may have an important role in occupational asthma induced by TDI.

Abstract
OBJECTIVE To elucidate molecular aspects of the mechanisms of expansion of chronic subdural haematomas (CSH), we examined the expression of two representative angiogenic factors, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in CSH. METHODS We quantified VEGF and bFGF in haematoma fluid and serum of 20 patients with CSH using an enzyme-linked immunosorbent assay. Mean concentrations of VEGF in the haematoma fluid (10277 pg/ml) and in serum, (355 pg/ml) were much greater than those of bFGF (haematoma, 3.04 pg/ml; serum, 4.74 pg/ml). Surgical specimens, including dura and the outer membrane of the CSH were analysed by in situ hybridisation to detect VEGF mRNA. Macrophages and vascular endothelial cells in the outer membrane over expressed VEGF mRNA. CONCLUSIONS Enhanced production of VEGF by macrophages and vascular endothelial cells in the outer membrane is thought to be pathogenetically important in CSH.
