Abstract
Photodynamic therapy is useful as organ-preservation salvage therapy for residual recurrence of esophageal squamous cell carcinoma after chemoradiation therapy. However, the high residual recurrence rate of photodynamic therapy poses a problem. We herein report a patient who underwent photodynamic therapy for recurrence of superficial esophageal squamous cell carcinoma after chemoradiation therapy. The patient later exhibited another episode of recurrence of superficial esophageal squamous cell carcinoma, and R0 curative resection was obtained with endoscopic submucosal dissection. This suggests that endoscopic submucosal dissection may be an effective treatment option that can achieve R0 resection even for residual superficial cancer after salvage photodynamic therapy.

Abstract
BACKGROUND Adult-onset Ménétrier’s disease is strongly associated with Helicobacter pylori (H. pylori) infection and an elevated risk of carcinogenesis. Cases of early-stage gastric cancer developed in H. pylori-negative Ménétrier’s disease are extremely rare. We report a case of early gastric cancer in H. pylori-negative Ménétrier’s disease that was curatively resected with endoscopic submucosal dissection (ESD).
CASE SUMMARY A 60-year-old woman was referred to our hospital after her medical examination detected anemia. Contrast-enhanced upper gastrointestinal (UGI) radiography revealed translucency of the nodule-aggregating surface with giant rugae. Blood tests showed hypoproteinemia and were negative for serum H. pylori immunoglobulin G antibodies. The 99mTc-DTPA-human serum albumin scintigraphy showed protein loss from the stomach. UGI endoscopy showed a 40-mm protruding erythematous lesion on giant rugae of the greater curvature of lower gastric body, suggesting early-stage gastric cancer due to Ménétrier’s disease. En bloc resection with ESD was performed for diagnosis and treatment. Histology of ESD showed well-differentiated tubular adenocarcinoma. The cancer was confined to the mucosa, and complete curative resection was achieved. Foveolar hyperplasia and atrophy of the gastric glands were observed in non-tumor areas, histologically corresponding to Ménétrier’s disease. Three years after ESD, gastric cancer had not recurred, and Ménétrier’s disease remained in remission with spontaneous regression of giant gastric rugae.
CONCLUSION Complete curative resection was achieved through ESD in a patient with early-stage gastric cancer and H. pylori-negative Ménétrier’s disease.

Abstract
BACKGROUND/AIM We generated a novel disease mouse model in which a fructose-containing western diet (FD) induces development of non-alcoholic steatohepatitis (NASH). MATERIALS AND METHODS C57BL/6J mice were fed FD for 60 weeks and body weight and blood pressure were monitored. Plasma cholesterol level was measured at the end of the experiments. Histopathology of NASH was examined by hematoxylin and eosin staining, Masson-Trichrome staining, periodic acid-Schiff staining, and immunohistochemistry against a proliferation marker. Circadian gene expression levels were compared by sampling the livers in 4-h intervals, followed by quantitative RT-PCR analysis. RESULTS FD-fed mice developed obesity, transient hypertension, hypercholesterolemia, and liver adiposity. The mice spontaneously developed hepatic nodules, which were diagnosed as non-neoplastic nodular regenerative hyperplasia. FD-fed mice had increased expression of growth factor genes and cirrhosis markers compared to control mice. Circadian expression of lipid metabolism genes was deregulated by FD intake. CONCLUSION C57BL/6J mice fed FD developed non-alcoholic steatohepatitis and nodular regenerative hyperplasia over time.

Abstract
BACKGROUND Esophageal adenocarcinoma (EAC) derived from long-segment Barrett’s esophagus (LSBE) is extremely rare in Asia. LSBE-related EAC is often difficult to diagnose in the horizontal extent. If the tumor has spread throughout the LSBE, whole circumferential endoscopic submucosal dissection (ESD) should be performed, which is difficult to complete safely. Additionally, whole circumferential ESD can bring refractory postoperative stenosis. We hereby report a case of EAC involving the whole circumference of the LSBE, achieving complete endoscopic removal without complications.
CASE SUMMARY An 85-year-old man with the chief complaint of dysphagia underwent esophagogastroduodenoscopy. We suspected a flat-type cancerous lesion that extended the whole circumference of the LSBE (C 3.5, M 4.0) using narrow-band imaging magnification endoscopy (NBI-M). We achieved circumferential en bloc resection of the lesion safely with special ESD techniques. Histology of the ESD specimens demonstrated that the superficial EAC extended the whole circumference of the LSBE, and papillary or well-differentiated tubular adenocarcinoma was confined in the lamina propria mucosa showing a vertical negative margin. To prevent post-ESD stenosis, we performed endoscopic local injection of steroids, followed by oral administration of steroids. There was no evidence of esophageal refractory stenosis or tumor recurrence 30 mo after ESD. In summary, we experienced a rare case of LSBE-related EAC. The horizontal tumor extent was accurately diagnosed by NBI-M. Additionally, we achieve whole circumferential ESD safely without postoperative refractory stenosis.
CONCLUSION NBI-M, ESD, and steroid therapy enabled the curative resection of superficial full circumferential LSBE-related EAC without refractory postoperative stenosis.

Abstract
Abstract
Background
Geriatric nutritional risk index (GNRI) was developed as a “nutrition-related” risk index and was reported in different populations as associated with the risk of all-cause and cardiovascular morbidity and mortality.
Purpose
The purpose of this study was to assess the associations of GNRI with mortality and amputation free survival in patients with peripheral artery disease (PAD).
Methods
From January 2011 to June 2016, 295 consecutive patients (73.3±9.2 years; 75.6% male) with PAD undergoing endovascular treatment (EVT) in our hospital were retrospectively examined. The GNRI on admission was calculated as follows: 14.89 × serum albumin (g/dl) + 41.7 × body mass index (BMI)/22. Characteristics and mortality were compared between 2 groups: low GNRI (<92, n=110) with moderate or severe nutritional risk; and high GNRI (≥92, n=185) with no or low nutritional risk.
Results
The median follow up period was 39.4±26.4months. There were 85 deaths (28.8%) and 13 major amputation (4.4%) during the follow-up. Patients in the low-GNRI group were more often higher age, non-ambulatory state, hemodialysis and critical limb ischemia. BMI, serum hemoglobin, albumin, low-density lipoprotein were significantly lower, whereas serum C-reactive protein was significantly higher in the low-GNRI group than the high-GNRI group (P<0.05, respectively). Kaplan–Meier analysis revealed that patients in the low-GNRI group had a significantly lower amputation free survival, compared to those in the high-GNRI group (log-rank test, P<0.001).
Conclusion
The low GNRI is associated with an increased risk of mortality and limb events in patients with PAD.

Abstract
Abstract
Background
While it is generally accepted that cardiac autonomic nervous system (CANS) plays an important role in atrial fibrillation (AF) and pulmonary vein isolation (PVI) by radiofrequency catheter ablation modifies the ganglionated plexi (GP), the alterations of CANS after PVI are not clarified.
Purpose
The objective of this study was to investigate the alteration of CANS after conventional cryoballoon ablation (CBA) by using a non-invasive examination method of measuring resting heart rate (R-HR) and coefficient of variation of R-R interval (CVR-R) which is a representative parameter of heart rate viability. CVR-R reflects R-R interval variation affected by respiration. It is calculated from the R-R interval of consecutive 100 heart beats of sinus rhythm recorded at rest. Declines of CVR-R indicate the parasympathetic dysfunction and the normal range of it varies depend on the age. As age increases from 30s to 70s, the average value of CVR-R decreases from 4.0% to 2.4%.
Methods
Consecutive patients of paroxysmal AF treated with initial CBA in our institute participated. Subjects were limited to the patients who maintained sinus rhythm through the study and whose prescription had not been changed after procedure. All patients recorded 12-lead electrocardiogram to measure R-HR and CVR-R before and the day after the procedure. We compared R-HR and CVR-R of all patients before and after CBA. And in addition, we compared them in each of two groups whose pre-procedural H-RH were under 50 bpm (Group-U50) and over 70 bpm (Group-O70). All procedures were performed with second generation 28mm cryoballoon (CB)s under the conscious sedation with Dexmedetomidine. CB temperature was down to a minimum of -60°C and target application time was 180 seconds.
Results
In the procedure of all 105 patients (male gender, 54%; age, 66.9 ± 10.4years; CHADS2score, 1.15 ± 1.04; diabetes mellitus,14%; beta-blocker therapy, 16%), 1 of touch-up for PVI, 6 of supra vena cava isolation and 21 of cavotricuspid isthmus linear ablations with radiofrequency catheter were added. In all patients, R-HR increased from 58.9 ± 9.2bpm to 72.4 ± 9.5bpm (P < 0.01) and CVR-R decreased from 2.36 ± 1.08% to 1.24 ± 0.68% (P < 0.01), respectively. In Group-U50 (n = 14; male gender 64%; age 67.6 ± 12.4 years), R-HR increased from 47.1 ± 2.1bpm to 64.4 ± 7.9bpm (P < 0.01) and CVR-R decreased from 2.58 ± 1.59% to 1.34 ± 0.82% (P < 0.01), respectively. In Group-O70 (n = 17; male gender 43%; age 67.4 ± 12.6 years), R-HR increased from 73.7 ± 2.8bpm to 81.8 ± 7.4bpm (P < 0.01) and CVR-R decreased from 2.33 ± 0.94% to 1.14 ± 0.52% (P < 0.01), respectively. Values of CVR-R before and after CBA showed no significant difference between the two groups.
Conclusions
After CBA, R-HR increment and CVR-R decrement were significantly observed. CVR-R was halved regardless of pre–procedural R-HR. Damages to GP by CBA would be reflected as denervation of vagus nerves in CANS. R-HR increase might be associated with parasympathetic suppression of CANS.

Abstract
BACKGROUND The concept of intraductal papillary neoplasm of the bile duct (IPNB) has been proposed to be the biliary equivalent of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. While the classification of IPMNs is based on their location of duct involvement, such classification has not been fully evaluated for IPNBs. The aim of this study is to investigate the value of IPNB classification based on its location. METHODS A total of 306 consecutive patients who underwent surgical resection with a diagnosis of bile duct tumor were enrolled. Among these patients, 21 were diagnosed as having IPNB. The IPNBs were classified into two groups as follows: extrahepatic IPNB, which located in the distal or perihilar bile duct, and intrahepatic IPNB, which located more peripherally than the hilar bile duct. The clinicopathological features of the two groups were then compared. RESULTS Extrahepatic IPNB tended to show more invasive characteristics than intrahepatic IPNB (presence of invasive component: 40.0 vs. 9.1%, p = 0.084). Moreover, patients with extrahepatic IPNB showed significantly poorer relapse-free survival (RFS) than those with intrahepatic IPNB [5-year RFS rate (%): 81.8 vs. 16.2, p = 0.014]. CONCLUSION Patients with intrahepatic IPNB show more favorable pathological characteristics and postoperative survival outcomes than those with extrahepatic IPNB.

Abstract
INTRODUCTION Cystic duct carcinoma is a rare disease, and only 33 cases reported worldwide have completely fulfilled the criteria first established by Farrar in 1951. Here we describe an extremely rare case of early cystic duct carcinoma that fulfilled the Farrar criteria, the papillary tumour protruding into the common bile duct, leading to obstructive jaundice. CASE PRESENTATION A 76-year-old man visited a clinic with icteric conjunctivae, and was referred to our hospital for investigation of suspected obstructive jaundice. He was initially diagnosed as having a distal bile duct carcinoma on the basis of ultrasonography (US), endoscopic retrograde cholangiopancreatography (ERCP), and magnetic resonance cholangiography (MRC), and underwent pancreatoduodenectomy with regional lymphadenectomy. Macroscopic examination showed that the stalk of the papillary tumour originated from the cystic duct, and that the protruding lesion was 50 mm in size. Histopathological examination revealed the tumour to be a papillary adenocarcinoma confined within the fibromuscular layer, with no evidence of lymph node metastasis. Therefore, the final diagnosis was early cystic duct carcinoma. CONCLUSION To our knowledge, this is the first case report of obstructive jaundice due to early carcinoma of the cystic duct protruding into the bile duct, with characteristics fulfilling the Farrar criteria.

Abstract
BACKGROUND The aim of this pilot study is to investigate the diagnostic yield of probe-based confocal laser endomicroscopy (pCLE) in the evaluation of depth of invasion in colorectal lesions. METHODS Patients with colorectal lesions eligible for either endoscopic treatment or surgery were enrolled in the study. Tumor's depth of invasion was classified as mucosal or slight submucosal (M-SM1) and deep submucosal invasion or deeper (SM2 or deeper). White light endoscopy (WLE), magnifying narrow band imaging (M-NBI), and magnifying chromoendoscopy (M-CE) were used to assess colorectal lesions, and pCLE was used to identify tumor's features related to SM2 or deeper. The diagnostic classification of depth of invasion was obtained by correlating pCLE findings with histology results (on-site diagnosis). All colorectal lesions were stratified by a second endoscopist who was blinded to any clinical and histological information with the use of WLE, M-NBI, M-CE, and pCLE (off-line review). RESULTS A total of 22 colorectal lesions were analyzed: seven were adenoma, ten intramucosal cancer, and five SM2 or deeper cancer. With respect to pCLE findings, loss of crypt structure was seen in all SM2 or deeper cancers and only in one M-SM1 lesion. Sensitivity, specificity, and accuracy of WLE, M-NBI, and M-CE in off-line review were 60/94/86, 60/94/86, and 80/94/91%, respectively. Sensitivity/specificity/accuracy of pCLE in off-line review were 80/94/91%, respectively. The inter-observer agreement of pCLE between on-site diagnosis and off-line review was 0.64 (95%CI 0.27-1.0). CONCLUSIONS pCLE may represent a useful tool to evaluate the depth of invasion in colorectal lesions.

Abstract
BACKGROUND Although submucosal dissection is useful for treating laterally spreading colorectal tumors, there is little information regarding the endoscopic treatment of large protruding colorectal neoplasms. Here, we aimed to evaluate the clinical outcomes of endoscopic submucosal dissection for protruding colorectal neoplasms ≥ 20 mm in diameter. METHODS In total, 112 consecutive patients undergoing treatment between January 2005 and June 2017 were enrolled retrospectively. The study period was divided into six periods to evaluate any changes in outcomes over time. We reviewed all short-term clinical outcomes, including lesion characteristics, procedure time, and percentages of en bloc resection, curative resection, adverse events, and treatment discontinuation. RESULTS The percentages of en bloc, en bloc R0, and en bloc curative resections were 88 %, 82 %, and 59 %, respectively. Perforation occurred in 11 patients (10 %), and the endoscopic procedure was discontinued in five patients (4 %) because of technical difficulty. For lesions ≥ 40 mm in diameter, the procedure time showed a statistically significant decreasing trend in the latter half of the study period. However, the rate of cure did not improve along with enhancements to the procedure's technological aspects. CONCLUSIONS Although endoscopic submucosal dissection for large protruding lesions has advanced in terms of its technical aspects, its ability to cure large protruding neoplasms has not shown gratifying results.

Abstract
A 78-year-old man underwent endoscopic submucosal dissection (ESD) for early gastric adenocarcinoma twice in 2009 and 2014. Between the procedures, he successfully completed Helicobacter pylori eradication therapy. In May 2015, upper endoscopy screening showed two elevated lesions on the gastric fundus, and en bloc resection by ESD was performed. We histopathologically diagnosed the patient to have gastric adenocarcinoma of the fundic gland type. In this case, the two lesions of gastric adenocarcinoma of the fundic gland type multifocally developed after ESD for metachronous gastric tubular adenocarcinoma. Furthermore, they appeared in the gastric fundus, where atrophy had been improved due to eradication therapy.

Abstract
Multiple attempts have been made to replace biliary defects with a variety of materials. Recently, successful biliary reconstruction using the Gore-Tex vascular graft has been reported experimentally and clinically We designed a new artificial bile duct consisting of collagen sponge and polypropylene mesh. We presently evaluated the feasibility of using this prosthesis as a scaffold for bile duct tissue regeneration in a canine model. Our prosthesis, a sponge made from porcine dermal collagen, is reinforced with a polypropylene mesh cylinder. We used the prosthesis to reconstruct the middle portion of the common bile duct in seven beagle dogs to evaluate its efficacy. While one dog died of biliary stricture 8 months after operation, six survived without problems to scheduled time points for tissue evaluation at 1 to 12 months. All prostheses had become completely incorporated into the host. A confluent epithelial lining was observed within 3 months. In cholangiograms the prosthesis displayed long-term patency in the six dogs and provided satisfactory bile drainage for up to 12 months. Our graft thus shows promise for repair of biliary defects and should lead to development of a new treatment for biliary reconstruction.

Abstract
AIM To evaluate the usefulness of total colonoscopy (TCS) for patients undergoing gastric endoscopic submucosal dissection (ESD) and to assess risk factors for colorectal neoplasms.
METHODS Of the 263 patients who underwent ESD at our department between May 2010 and December 2013, 172 patients undergoing TCS during a one-year period before and after ESD were targeted. After excluding patients with a history of surgery or endoscopic therapy for colorectal neoplasms, 158 patients were analyzed. Of the 868 asymptomatic patients who underwent TCS during the same period because of positive fecal immunochemical test (FIT) results, 158 patients with no history of either surgery or endoscopic therapy for colorectal neoplasms who were matched for age and sex served as the control group for comparison.
RESULTS TCS revealed adenoma less than 10 mm in 53 patients (33.6%), advanced adenoma in 17 (10.8%), early colorectal cancer in 5 (3.2%), and advanced colorectal cancer in 4 (2.5%). When the presence or absence of adenoma less than 10 mm, advanced adenoma, and colorectal cancer and the number of adenomas were compared between patients undergoing ESD and FIT-positive patients, there were no statistically significant differences in any of the parameters assessed. The patients undergoing ESD appeared to have the same risk of colorectal neoplasms as the FIT-positive patients. Colorectal neoplasms were clearly more common in men than in women (P = 0.031). Advanced adenoma and cancer were significantly more frequent in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus (P = 0.019).
CONCLUSION In patients undergoing gastric ESD, TCS appears to be important for detecting synchronous double neoplasms. Advanced adenoma and cancer were more common in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus. Caution is therefore especially warranted in patients with these risk factors.

Abstract
We have recently shown that loss of the regenerating gene (Reg) I causes susceptibility to nonsteroidal anti-inflammatory drug-induced gastrointestinal damage. However, the mechanism by which Reg I plays a protective role against this pathophysiological condition is unclear. Here, we investigated whether Reg I plays roles in the induction of tight junction proteins and mucosal barrier function in the small intestine. The small-intestinal permeability was evaluated in Reg I-deficient mice by FITC-dextran and transepithelial electrical resistance (TEER) assay. The effect of REG Iα on TEER, claudins expression, and intracellular signaling was examined using Caco2 cells in vitro. Small-intestinal expression of claudins 3 and 4 was investigated in Reg I-deficient mice in vivo. REG I deficiency significantly decreased the expression of claudin 3 in the small-intestinal epithelium. When mice were treated with indomethacin, the serum level of FITC-dextran in Reg I knockout mice was significantly higher than that in wild-type (WT) mice. The level of small-intestinal TEER was significantly decreased in Reg I knockout mice compared with WT mice under normal condition. REG Iα stimulation significantly enhanced the level of TEER in Caco2 cells. Treatment with REG Iα enhanced the expression of claudins 3 and 4 and promoted Sp1, Akt, and ERK phosphorylation in Caco2 cells, whereas these effects were attenuated by treatment with anti-REG Iα antibody. Reg I may play a role in the maintenance of mucosal barrier function by inducing tight junction proteins such as claudins 3 and 4.

Abstract
Colorectal cancer (CRC) results from the progressive accumulation of genetic and epigenetic alterations that lead to the transformation of normal colonic mucosa to adenocarcinoma. Approximately 75% of CRCs are sporadic and occur in people without genetic predisposition or family history of CRC. During the past two decades, sporadic CRCs were classified into three major groups according to frequently altered/mutated genes. These genes have been identified by linkage analyses of cancer-prone families and by individual mutation analyses of candidate genes selected on the basis of functional data. In the first half of this review, we describe the genetic pathways of sporadic CRCs and their clinicopathologic features. Recently, large-scale genome analyses have detected many infrequently mutated genes as well as a small number of frequently mutated genes. These infrequently mutated genes are likely described in a limited number of pathways. Gene-oriented models of CRC progression are being replaced by pathway-oriented models. In the second half of this review, we summarize the present knowledge of this research field and discuss its prospects.

Abstract
We herein report five cases of ulcerative colitis-associated cancer/dysplasia. Although clinical remission had been achieved in all patients, mucosal inflammation had been resolved in only one patient. Thus, in order to prevent cancer from developing, appropriate medical therapy aiming not only to relieve the clinical symptoms, but also to suppress chronic inflammation appears to be necessary. Moreover, cancer occurred as early as 4 years after the diagnosis in one patient. In patients without complete resolution of mucosal inflammation, careful surveillance colonoscopy should be initiated in the early phase.

Abstract
AIM: To assess the safety of single-incision laparoscopic cholecystectomy (SILC) for acute cholecystitis.
METHODS: All patients who underwent SILC at Sano Hospital (Kobe, Japan) between January 2010 and December 2014 were included in this retrospective study. Clinical data related to patient characteristics and surgical outcomes were collected from medical records. The parameters for assessing the safety of the procedure included operative time, volume of blood loss, achievement of the critical view of safety, use of additional trocars, conversion to laparotomy, intraoperative and postoperative complications, and duration of postoperative hospital stay. Patient backgrounds were statistically compared between those with and without conversion to laparotomy.
RESULTS: A total of 100 patients underwent SILC for acute cholecystitis during the period. Preoperative endoscopic treatment was performed for suspected choledocholithiasis in 41 patients (41%). The mean time from onset of acute cholecystitis was 7.7 d. According to the Updated Tokyo Guidelines (TG13) for the severity of cholecystitis, 86 and 14 patients had grade I and grade II acute cholecystitis, respectively. The mean operative time was 87.4 min. The mean estimated blood loss was 80.6 mL. The critical view of safety was obtained in 89 patients (89%). Conversion laparotomy was performed in 12 patients (12%). Postoperative complications of Clavien-Dindo grade III or greater were observed in 4 patients (4%). The mean duration of postoperative hospital stay was 5.7 d. Patients converted from SILC to laparotomy tended to have higher days after onset.
CONCLUSION: SILC is feasible for acute cholecystitis; in addition, early surgical intervention may reduce the risk of laparotomy conversion.

Abstract
Early studies characterizing the keratin (K) profile of various epithelial tissues indicated that breast carcinoma is K7 positive and K20 negative, but not all breast carcinomas show this profile. Triple-negative carcinoma (TNC) has been characterized by negativity for estrogen receptor (ER), progesterone receptor (PgR), and Her2/neu protein. TNC is more likely to metastasize to the viscera and present as a metastatic poorly different carcinoma. In our study, on the basis of immunohistochemical staining of ER, PgR, and Her2/neu, 75 of the 290 patients with invasive breast carcinoma were judged to have TNC. K20 expression was detected in 6 of 75 patients with TNC, and non-TNC was negative in all 215 cases (P = .0003). K7 expression was also detected in 72 of 75 TNC cases. However, non-TNC was negative in 26 of 215 cases, which was significant (P = .0457). An aberrant profile of K was observed in the TNC group, indicating that caution is needed in determining the site of primary tumors using immunohistochemical algorithms. It should be kept in mind that patients with TNC show highly variable K profiles in practical diagnosis.

Abstract
This study attempted to clarify the clinicopathological and immunohistochemical findings and presence or absence of Epstein-Barr virus (EBV) in tonsillar atypical interfollicular hyperplasia (AIFH). A total of 597 consecutive specimens from tonsillectomies performed in Dokkyo University School of Medicine between 1999 and July 2013 were reexamined. Using formalin-fixed, paraffin-embedded sections, histological and immunohistochemical analyses, and in situ hybridization (ISH) were performed. AIFH was identified in the tonsils in 12 (2.0%) cases. These included 7 males and 5 females, aged 3 to 19 years (mean, 7). Histologically, there was expansion of the interfollicular areas by polymorphous infiltration resulting in distortion, but not obliteration of the normal tonsillar architecture. In some areas, the lymphoid follicles had hyperplastic germinal centers with ill-defined borders surrounded by sheet-like proliferation of polymorphous infiltrate showing a marginal zone distribution pattern. The infiltrate was composed of small to medium-sized (transformed) lymphocytes and immunoblasts accompanied by numerous plasma cells and plasmacytoid cells, and resembling monocytoid B cells. The numerous immunoblasts were MUM1(+), CD10(-), BCL-6(-). An ISH study demonstrated EBV-encoded small RNA-1 (EBER-1)(+) cells in 9 lesions. Moreover, in 3 lesions, numerous EBER-1(+) cells were present in germinal centers as well as in interfollicular areas. The present study indicated that EBV may cause at least a portion of tonsillar AIFH in children and adolescents. In conclusion, an atypical lymphoid infiltration resulting in distortion of tonsillar architecture with numerous MUM1(+), CD10(-), BCL-6(-) immunoblasts should raise the suspicion of a reactive process.

Abstract
Regenerating gene (Reg) family proteins, which are classified into four types, commonly act as trophic and/or antiapoptotic factors in gastrointestinal (GI) diseases. However, it remains unclear how these proteins coordinate their similar roles under such pathophysiological conditions. Here, we investigated the interrelationships of Reg family gene expression with mucosal cell proliferation and apoptosis in nonsteroidal anti-inflammatory drug (NSAID)-induced GI injury. GI injury was induced by subcutaneous injection of indomethacin into Reg I knockout (KO) and wild-type (WT) mice, and its severity was scored histopathologically. Temporal changes in the expression of Reg family genes, mucosal proliferation, and apoptosis were evaluated throughout the GI tract by real-time RT-PCR, Ki-67 immunoreactivity, and TUNEL assay, respectively. Reg I, Reg III family, and Reg IV were predominantly expressed in the upper, middle, and lower GI mucosa, respectively. Expression of Reg I and Reg III family genes was upregulated in specific portions of the GI tract after indomethacin treatment. Ki-67-positive epithelial cells were significantly decreased in the gastric and small-intestinal mucosa of Reg I KO mice under normal conditions. After treatment with indomethacin, the number of TUNEL-positive cells was significantly greater throughout the GI mucosa in Reg I KO mice than in WT mice. Expression of Reg I was independent of that of other Reg family genes in, not only normal GI tissues, but also indomethacin-induced GI lesions. Members of the Reg gene family show distinct profiles of expression in the GI tract, and Reg I independently plays a role in protecting the GI mucosa against NSAID-induced injury.

Abstract
BACKGROUND Tegafur-gimeracil-oteracil potassium (TS-1)is a drug that is used mainly as a third-line treatment or beyond for metastatic breast cancer(MBC). However, there is still insufficient evidence on its clinical effectiveness, and there are very few reports on clinical research using TS-1 up front. In this report, we examined the effectiveness and safety of TS-1 therapy for MBC. PATIENTS AND METHODS The subjects were 46 patients with MBC who were treated with TS-1 between January 2005 and January 2013. These patients were retrospectively examined. RESULTS The objective response rate to TS-1 therapy was 30.4%, clinical benefit rate (CBR)was 50.0%, and the median time to treatment failure was 10.7 months. When examined by site, the CBR was high locally (46.2%), in the lymph nodes (40.7%), in the bone (42.9%), and in the lungs and pleura (44.8%). However it was low in the liver(30.0%). The relationship was examined between clinicopathological factors and the effectiveness of TS-1 therapy. The objective response rate (ORR) was significantly higher for patients with disease-free interval (DFI) of 2 years or more (p=0.039), TS-1 therapy used as third-line treatment or earlier (p=0.022), negative HER2 status (p=0.020), and no history of capecitabine (CAP)therapy (p=0.049). The CBR was significantly higher for patients with no visceral metastasis (p=0.032), TS-1 used as third-line treatment or earlier (p=0.019), negative HER2 status (p= 0.045), no history of CAP therapy (p=0.006), and no history of tegafur-uracil/doxifluridine therapy (p=0.031). Multivariate analysis showed that DFI of 2 years or more (p=0.035, odds ratio:0.104)was an independent predictor of effectiveness assessed by ORR. There were only 4 patients in whom the treatment was discontinued due to adverse event, and TS-1 was generally well tolerated. CONCLUSION TS-1 was highly effective and well tolerated by patients with MBC. Its up-front use might enable the maintenance of satisfactory QOL and the enhancement of its clinical effectiveness.

Abstract
OBJECTIVE To evaluate the usefulness of a novel high-resolution magnifying videoendoscope called the XG-0001 (Fujifilm, Tokyo, Japan) that is capable of PDD and PDT in experimental and clinical situations. MATERIALS AND METHODS The fluorescences of three photosensitizers (i.e., porfimer sodium (Photofrin), protoporphyrin IX and talaporfin sodium (Laserphyrin)) were studied experimentally via excitation with a purple diode laser (VDL, wavelength 405nm). Five consecutive patients with superficial early gastric cancer not indicated for surgery or other curative endoscopic treatment due to complicated serious diseases were enrolled in this study. After close endoscopic examinations, 2mg/kg of Photofrin were intravenously injected into the patients for PDT, and 5-aminolevulinic acid (ALA; 15-20mg/kg) was orally taken for PDD. PDD using VDL and PDT using an excimer-dye laser (630nm, 4mJ, 60Hz) were performed with the XG-0001. RESULTS Photofrin and Laserphyrin had experimentally the lowest and highest fluorescence intensities, respectively. The five patients comprised four men and one woman with a mean age 75.2 year and an age range of 56-83 years. Two additional cancerous lesions were newly detected by magnifying pharmacoendoscopy. In each patient, PDD was successfully performed. PDT could also safely performed and CR was obtained in 71.4% (5/7) of the cancerous lesions in five patients, and no serious complications were encountered. CONCLUSION The XG-0001, which is based on a simultaneous videoendoscopy method that uses an RGB color chip CCD, proved extremely useful in routine use and also in PDD and PDT for gastric cancer.

Abstract
The efficacy of tolvaptan for treating heart failure has already been shown. Adequate data relating to the effect of tolvaptan on the correlation of water balance in renal disease are not available. A retrospective study was conducted on the efficacy and adverse reactions of tolvaptan for treating nephrotic syndrome.The subjects were 26 patients with chronic kidney failure due to diabetic nephropathy with heart failure who were administered tolvaptan and seen between December 2011 and October 2013. The endpoints were urinary output, physical findings, and blood analyses. The expression of aquaporin-2 in the collecting duct, which is related to the action of tolvaptan, was investigated by immunohistochemistry using the kidney tissue obtained for the diagnosis.Responses were seen in 19 of the patients. In the histopathological investigation there was severe glomerulosclerosis in patients with diabetic nephropathy, but the responders were noticeable in that they only had mild tubulointerstitial damage. Non-responders exhibited profound tubulointerstitial damage. The expression of aquaporin-2 was determined in 8 patients, of which 7 were responders who tested positive for aquaporin-2. The remaining case was a non-responder who showed no expression of aquaporin-2.Tolvaptan is considered effective for some cases of nephrotic syndrome. There are no clear parameters for predicting an effect, but the present study showed that aquaporin-2 was expressed in the epithelial cells of the collecting ducts of tolvaptan responders.

Abstract
BACKGROUND Among various preoperative evaluations of liver function, accurate assessment of liver cirrhosis (LC) is especially important in patients undergoing surgery for hepatocellular carcinoma (HCC). OBJECTIVE To explore the most significant laboratory parameter associated with LC in patients undergoing surgery for HCC. METHODS From among 588 HCC patients in our collected database who underwent liver surgery, 371 for whom sufficient laboratory data were evaluable, including direct serum fibrosis markers such as hyaluronic acid and type 3 procollagen peptide (P-3-P), were enrolled. Receiver operating characteristic (ROC) curve analysis was used to define the ideal cutoff values of laboratory parameters, and the area under the ROC curve for LC was measured. Univariate and multivariate analyses were performed to clarify the laboratory parameter most significantly associated with LC. RESULTS Multivariate analysis of 13 laboratory parameters that had been selected by univariate analysis showed that the aspartate aminotransferase-to-platelet ratio index (APRI) (≤ 0.8/>0.8) (odds ratio, 2.687; 95% confidence interval 1.215-5.940; P = 0.015) was associated with LC, along with the aspartate aminotransferase to alanine aminotransferase ratio, the indocyanine green retention ratio at 15 min (ICG R15), and the level of hyaluronic acid. Among these four parameters associated with LC, ROC curve analysis revealed that APRI (0.757) had the largest area under the ROC (aspartate aminotransferase to alanine aminotransferase 0.505, ICG R15 0.714, and hyaluronic acid 0.743). CONCLUSIONS APRI is closely associated with LC in patients undergoing surgery for HCC.

Abstract
BACKGROUND Aromatase inhibitors(AI)have established efficacy as first-line therapy in postmenopausal patients with hormone-sensitive metastatic breast cancer(MBC). However,the use of endocrine therapy has not yet been established for second-line and later therapy. Our study examined the efficacy of high-dose toremifene therapy(HD-TOR)in patients with MBC resistant to AIs. PATIENTS AND METHODS A retrospective analysis was carried out to determine outcomes in 85 postmenopausal patients with MBC resistant to AIs who began HD-TOR between May 2001 and October 2011. The patients received toremifene 120 mg once daily on consecutive days. RESULTS The objective response rate(ORR)was 21.2%,the clinical benefit rate(CBR)was 41.2%,and the median time to treatment failure(TTF)was 7.3 months. The CBR was high in patients with ER-positive status(p=0.045),no visceral metastasis(p=0.037),HD -TOR as first- or second-line therapy(p=0.007),no history of tamoxifen(TAM)therapy(p=0.019),and no history of chemotherapy(p=0.017). Multivariate analysis showed that ER-positive status(p=0.005, odds ratio: 0.064)and no visceral metastasis(p=0.034, odds ratio: 0.323)were independent predictors of efficacy. The TTF was significantly longer in patients with ER-positive status(p=0.019)and no history of TAM therapy(p=0.015). Multivariate analysis showed that ER-positive status(p=0.025, hazard ratio: 0.377)and no history of TAM therapy(p=0.002, hazard ratio: 0.422)were independent predictors of efficacy. No patient discontinued HDTOR therapy due to adverse events. CONCLUSION HD-TOR is an effective endocrine therapy for patients with MBC who have failed AIs.

Abstract
Bleeding is one of the serious adverse events of bevacizumab (BV). In our report, two patients had locally advanced breast cancer with bleeding. They received BV plus weekly paclitaxel (PTX), and good local control was observed. Case 1: The patient was a 50-year-old postmenopausal woman. She had left-sided breast cancer (T4cN2cM1 [bone]-stageIV) that was negative for estrogen receptor (ER), negative for progesterone receptor(PgR), and 1+for human epidermal growth factor receptor 2 (HER2). The patient began receiving different regimens of chemotherapy: 5-fluorouracil (5-FU), epirubicin (EPI), and cyclophosphamide(CPA), (FEC); PTX; docetaxel (DTX); and gemcitabine (GEM) plus PTX. Subsequently, she received BV plus PTX. The tumor was markedly reduced in size at the completion of 2 cycles. Bleeding and exudate were also reduced. The patient had a partial response until the sixth cycle, and good local control was obtained. However, the patient had progressive disease at the completion of 8 cycles. Therefore, therapy was changed to capecitabine(CAP)plus CPA, but the patient died one year after she began treatment with BV plus PTX. Case 2: The patient was a 76-year-old postmenopausal woman. She had right-sided breast cancer (T4bN3bM1[lung]-stageIV) that was negative for ER, negative for PgR, and 0 for HER2. The patient began receiving different regimens of chemotherapy: EPI and CPA (EC); and PTX. Subsequently, she received BV plus PTX. The tumor was markedly reduced in size at the completion of 2 cycles. Bleeding and exudate were also reduced. The patient had a partial response until the third cycle, and good local control was obtained. However, the patient had progressive disease at the completion of 4 cycles. Therefore, therapy was changed to CAP and DTX, but the patient died six months after she began treatment with BV plus PTX.

Abstract
BACKGROUND/AIM Cytokeratin (CK) 20 expression is an independent prognostic factor of poorly differentiated adenocarcinoma (PDA) of the colon and rectum. We aimed to investigate the mechanism of its involvement through a clinicopathological study. PATIENTS AND METHODS We analyzed 156 surgically resected PDAs, which were sub-classified as solid type (Por1) showing expansive growth, or non-solid type (Por2) showing infiltrative growth. Associations of CK20 expression with morphological features and molecular markers were analyzed. RESULTS CK20(+) PDA (n=91) was associated with more advanced disease stage and unfavorable prognosis compared with CK20(-) PDA (n=65). Pathologically, CK20(+) PDA was significantly associated with p53 overexpression, Por2, abundant fibrous stroma, and stepwise de-differentiation, while CK20(-) PDA was significantly associated with mismatch repair deficiency, Por1, sparse fibrous stroma, and de novo histogenesis. CONCLUSION CK20 expression in PDA is closely associated with invasive histological features, providing prognostic significance, and may also point to a specific histogenetic pathway.

Abstract
Diffuse pulmonary arteriovenous malformations (AVMs) are associated with a poor prognosis and the therapeutic strategy remains controversial. We describe a pediatric patient with diffuse pulmonary AVMs associated with hereditary hemorrhagic telangiectasia (HHT), who presented with two cerebral AVMs in the parietal and occipital lobes as well. Of note, successful bilateral lung transplantation not only improved the hypoxemia but also resulted in size reduction of the cerebral AVMs. Although it is essential to consider involvements other than pulmonary AVMs, especially brain AVMs, to decide the indication, lung transplantation can be a viable therapeutic option for patients with diffuse pulmonary AVMs and HHT.

Abstract
BACKGROUND AND AIM The cytokeratin (CK)7(-) /CK20(+) immunoprofile is characteristic of colorectal carcinoma (CRC), although CK7(+) or CK20(-) phenotypes are occasionally encountered, particularly in histologically variant CRCs. We analyzed CK7/CK20 profiles in variant CRCs in association with clinicopathologic parameters and prognosis. METHODS CK expression in well- and moderately differentiated adenocarcinoma (WMDA) (n = 63), poorly differentiated adenocarcinoma (PDA) (n = 91), mucinous adenocarcinoma (MUA) (n = 81), signet-ring cell carcinoma (SRCC) (n = 15), undifferentiated carcinoma (UDC) (n = 12), and adenosquamous carcinoma (n = 2) was analyzed using immunohistochemistry. Cut-off scores were set at 1% for CK7 and 25% for CK20 using the receiver operating characteristic curve analysis of PDA. Association between CK20(-) and better prognosis in PDA was validated in the second cohort (n = 66). RESULTS CK7/CK20 immunoprofiling revealed a predominant CK7(-) /CK20(+) profile in WMDA, MUA, and SRCC, while the majority of UDC was characterized by a CK7(-) /CK20(-) profile. The CK7/CK20 profile in PDA was variable. Contingency table analysis revealed that CK expression was not significantly associated with any clinicopathologic parameters in WMDA, PDA, and MUA. However, survival analysis demonstrated that CK20(-) was significantly associated with better prognosis in PDA. Although CK20(-) was significantly associated with mismatch repair deficiency in PDA, it was an independent prognostic factor in multivariate analysis. Finally, we confirmed that CK20 status, determined using a 25% cut-off score, was a significant prognostic parameter in the second PDA cohort. CONCLUSIONS CK20 status may be used as a prognostic predictor of PDA.

Abstract
AIM: To investigate mucin expression profiles in colorectal carcinoma (CRC) histological subtypes with regard to clinicopathologic variables and prognosis.
METHODS: Mucin (MUC)2 and MUC5AC expressions were assessed by immunohistochemistry for a total of 250 CRC cases that underwent surgical resection. CRCs included 63 well-to-moderately differentiated adenocarcinomas (WMDAs), 91 poorly differentiated adenocarcinomas (PDAs), 81 mucinous adenocarcinoma (MUAs), and 15 signet-ring cell carcinomas (SRCCs). MUC2 and MUC5AC were scored as positive when ≥ 25% and ≥ 1% of cancer cells were stained positive, respectively. The human mutL homolog 1 and human mutS homolog 2 expressions were assessed by immunohistochemistry in PDAs to investigate mismatch-repair (MMR) status. Tumors that did not express either of these two were considered MMR-deficient. Results were analyzed for associations with clinicopathologic variables and the prognosis in individual histological CRC subtypes.
RESULTS: MUC2-positive and MUC5AC-positive WMDA percentages were 49.2% and 30.2%, respectively. In contrast, MUC2-positive and MUC5AC-positive PDA percentages were 9.5% and 51.6%, respectively. MUC2 levels tended to decrease and MUC5AC levels tended to increase from WMDA to PDA. In 21 tumors comprising both adenoma and adenocarcinoma components in a single tumor (4 WMDAs, 7 PDAs, and 10 MUAs), MUC2 was significantly downregulated in PDA and MUC5AC was downregulated in PDA and MUA in the adenoma-carcinoma sequence. These results suggested that MUC2 levels might be associated with malignant potential and that MUC5AC expression was an early event in tumorigenesis. Despite worse prognoses than WMDA, high MUC2 expression levels were maintained in MUA (95.1%) and SRCC (71.5%), which suggested a pathogenesis for these subtypes distinct from that of WMDA. No significant associations were found between MUC2 expression and any clinicopathologic variables in any histological subtype. MUC5AC expression in PDA was closely associated with right-sided location (P = 0.017), absence of nodal metastasis (P = 0.010), low tumor node metastasis stage (P = 0.010), and MMR deficiency (P = 0.003). MUC2 expression in WMDA was a marginal prognostic factor for recurrence/metastasis-free survival (RFS) by univariate Cox analysis (P = 0.077) but not by multivariate Cox analysis (P = 0.161). MUC5AC expression in PDA was a significant prognostic factor for RFS by univariate Cox analysis (P = 0.007) but not by multivariate Cox analysis (P = 0.104). Kaplan-Meier curves and log-rank tests revealed that MUC2 expression was marginally associated with a better WMDA prognosis [P = 0.064 for RFS and P = 0.172 for overall survival (OS)] but not for PDA. In contrast, MUC5AC expression was significantly and marginally associated with a better PDA prognosis in terms of RFS and OS, respectively (P = 0.004 for RFS and P = 0.100 for OS), but not for WMDA and MUA.
CONCLUSION: Mucin core protein expression profiles and clinical significance differ according to histological CRC subtypes. This may reflect different pathogeneses for these tumors.

Abstract
Background Paclitaxel plus bevacizumab have shown a high response rate and prolonged progression-free survival in metastatic breast cancer patients. However, overall survival was not prolonged. Thus, no conclusion has been made on the effectiveness of bevacizumab. In our report, taxane plus bevacizumab were used to treat a metastatic breast cancer patient with taxane resistance, and a good therapeutic result was obtained. Case presentation The patient was a 68-year-old woman with a non-contributory history. In September 2004, she underwent a pectoral muscle-conserving mastectomy with axillary dissection for right-sided breast cancer (pT3N0M0-stage IIB, estrogen receptor positive, progesterone receptor negative, and human epidermal growth factor receptor type 2 negative). Adjuvant therapy consisted of 6 cycles of cyclophosphamide, epirubicin and fluorouracil, and subsequent oral anastrozole. In August 2007, the patient developed a recurrence in the left axillary lymph node. The chemotherapy was changed to high-dose toremifene, and radiation therapy was also performed. The patient achieved a complete response. In April 2009, CT showed left axillary lymph node enlargement once again and multiple lung metastases. Hormone therapy was changed to exemestane and long-term stable disease was achieved. In March 2011, the lung and left axillary lymph node metastases were enlarged and progressive disease was noted. Thus, the tumors were determined to be resistant to hormone therapy, and weekly paclitaxel was begun in May. Since partial response was achieved, this therapy was continued. In December, CT showed that lung and axillary lymph node metastases were enlarged and progressive disease was observed. Therefore, the tumors were determined to be resistant to paclitaxel. In January 2012, bevacizumab and weekly paclitaxel were begun. In April, lung and axillary lymph node metastases were reduced in size, and partial response was achieved. Thereafter the same treatment has been continued, and the patient has been followed up without clinical exacerbation as of January 2013. Conclusion Taxane plus bevacizumab were used to treat a metastatic breast cancer patient with taxane resistance, and a good therapeutic result was obtained. This result is considered important in increasing treatment options for patients with taxane resistance or patients using adjuvant taxane-based therapy and in examining the effectiveness of bevacizumab in metastatic breast cancer patients.

Abstract
In order to determine the molecular basis of cytoplasmic male sterility (CMS) in alloplasmic lines of eggplant, the genomic structures and transcription patterns of mitochondrial ATP synthase subunit (atp) and cytochrome oxidase subunit (cox) genes were studied for wild and cultivated eggplants. Alloplasmic eggplant lines with cytoplasms of wild Solanum species showing either anther indehiscent type of CMS or non-pollen production type of CMS were studied with the cultivated eggplant Solanum melongena, used as a control. Southern hybridization of the mitochondrial genes indicated the difference between the two types of CMS and showed complete identity within each type. The cytoplasmic patterns of all wild species differed from that of the cultivated eggplant. Thus, the cytoplasm of the six wild eggplants and the one cultivated eggplant was classified into three groups. Male sterile plants of both types of CMS showed novel transcription patterns of atp1, whereas a different transcription pattern of cox2 was observed only in the anther indehiscent type. Based on these differences, we determined the DNA sequences of about a 4 kbp segment in the atp1 region. Although the coding and 3' flanking regions were almost identical among the cytoplasms, the 5' flanking region was completely different and novel open reading frames (orfs) were found for each of the CMS types and the cultivated eggplant. The cytoplasm of Solanum kurzii inducing the anther indehiscent type CMS had orf312, and those of Solanum aethiopicum and Solanum grandifolium of non-pollen production type CMS had orf218. The correspondence between the transcription patterns of these orfs and phenotypic expression of male sterility strongly suggests that these orfs are causal genes for each type of CMS.

Abstract
Stem cells are undifferentiated cells capable of proliferation, self-renewal, and production of a large number of differentiated progeny. Stem cells exist even in malignancies. They are called cancer stem cells, which may represent the origin of these tumors and may be one of the reasons of chemoresistance. The phosphatidylinositol-3-kinase (PI3K)/Akt pathway is important for the maintenance of pluripotency in stem cells. Flow cytometry assay for identifying stem cells defines a side population of cells that displays low fluorescent dye and is highly enriched for stem cells. The dye efflux is attributed to expression of ATP-binding cassette transporters such as P-glycoprotein and breast cancer resistance protein (BCRP)/ABCG2, which also transport a variety of anticancer drugs. The PI3K/Akt pathway can modulate functions of ABC transporters through various mechanisms. Reportedly, inhibition of the PI3K/Akt pathway caused BCRP translocation in hematopoietic stem cells and glioma stem-like cells. On the other hand, a PI3K inhibitor, LY294002, reversed multidrug resistance in cancer cells that overexpress BCRP not by affecting BCRP translocation but putatively as a competitive inhibitor. Other PI3K inhibitors, wortmannin and PI-103, did not reverse BCRP-mediated drug resistance. Since LY294002 is a derivative of quercetin that is a naturally occurring flavonoid, its chemical structure is similar to those of a group of flavonoids but those of wortmannin and PI-103 are quite different. It is known that many flavonoids are inhibitors of BCRP and PI3K. LY294002 has also been reported to exert inhibitory effects on multidrug resistance-associated protein 1 (MRP1) function via dual mechanisms, competitive block of substrate transport and modulation of expression. Furthermore, LY294002 has been found to antagonize transport activity of P-glycoprotein without influencing its expression. Taken together, LY294002 can inhibit all BCRP, P-glycoprotein, and MRP1, which are three major ABC transporters that are highly expressed in stem cells and cause multidrug resistance. Due to its versatile effects, LY294002 could be a lead compound for developing more effective and tolerable reagents for cancer treatment.

Abstract
Cellular responses toward cytotoxic drugs are influenced by cross-talk between oncogenic signals and resistance mechanisms. Inhibition of the PI3K/Akt pathway is effective in sensitizing cancer cells of various organs, although the mechanisms have largely remained to be elucidated. Breast cancer resistance protein (BCRP)/ABCG2, a drug efflux pump, confers resistance to multiple anticancer agents such as SN-38 and topotecan. Previous studies reported that inhibition of the PI3K/Akt pathway, by gene knockout or PI3K inhibitors, modulated BCRP-mediated drug transport via BCRP translocation in hematopoietic stem cells, renal polarized cells, and glioma stem-like cells of mammals. In this paper, we tested reversing effects of PI3K inhibitors, LY294002 and wortmannin, on BCRP-mediated anticancer drug resistance of human cancer MCF-7 and A431 cells. LY294002 definitely reversed BCRP-mediated SN-38 and topotecan resistances but wortmannin did not. LY294002 treatment affected neither total nor cell surface BCRP levels by western blotting and flow cytometry but blocked BCRP-mediated topotecan efflux in a dose-dependent manner. Immunohistochemical analyses also demonstrated unchanged cellular BCRP distribution. BCRP overexpression in MCF-7 and A431 cells did not confer LY294002 resistance, suggesting that LY294002 would not be a transported substrate of BCRP. LY294002 is a derivative of quercetin, a member of flavonoid. Taken together, these results suggest that LY294002 inhibits BCRP-mediated drug transport not by BCRP translocation through the PI3K/Akt signal but putatively as a competitive inhibitor in a major subset of cancer cells. Due to its dual effects, LY294002 could be a lead compound for developing more effective and tolerable reagents for cancer treatment.

Abstract
OBJECTIVES Tetraploid cells are strictly biologically inhibited from composition of embryos; by the same token, only diploid cells compose embryos. However, the distinction between diploid and tetraploid cells in development has not been well explained. To examine pluripotency of polyploid ES cells, a polyploid embryonic stem (ES)-cell system was prepared. MATERIALS AND METHODS Diploid, tetraploid, pentaploid, hexaploid, octaploid and decaploid H1 (ES) cells (2H1, 4H1, 5H1, 6H1, 8H1 and 10H1 cells, respectively) were cultured for about 460 days in L15F10 medium without leukaemia inhibitory factor (LIF). The cells cultured under LIF-free conditions were denoted as 2H1(-), 4H1(-), 5H1(-), 6H1(-), 8H1(-) and 10H1(-) cells, respectively. Pluripotency and gene expression were examined. RESULTS Ploidy alteration of H1(-) cells was similar to that of H1 cells. The polyploid H1(-) cells showed positive activity of alkaline phosphatase, suggesting that they maintained pluripotency in vitro without LIF. The polyploid H1(-) cells formed teratocarcinomas in mouse abdomen, suggesting they could differentiate in mouse abdomen in vivo. 2H1, 4H1 and polyploid H1(-) cells expressed nanog, oct3/4 and sox2 genes, suggesting that they fulfilled the criteria of ES cells. Nanog gene was significantly over-expressed in 4H1 and polyploid H1(-) cells, suggesting that overexpression of nanog gene was a characteristic of polyploid H1 cells. CONCLUSION Polyploid H1 (ES) cells retained pluripotency in vitro, without LIF with nanog over-expression.

Abstract
We herein present a case of IIc-like metastatic lung cancer that was detected early. A 65-year-old man presented with diarrhea and difficulty walking. Colonoscopy demonstrated a depressed lesion in the descending colon. However, the appearance of the lesion by endoscopy with a magnifying objective was not compatible with early colon cancer. Therefore, we performed diagnostic endoscopic mucosal resection to allow for an examination of the whole lesion. A histological examination demonstrated lung cancer metastasis to the colon. Only 1.6% of lung cancers metastasize to the large intestine, and metastatic colorectal cancer is not usually detected at an early stage. In the present case, however, endoscopy and a histological examination revealed alterations in the mucosal configuration of the lesion, which were unusual for early colon cancer.
