Abstract
Infancy associated eosinophilic pustular folliculitis (I-EPF) is a clinical variant of EPF that develops in childhood. Previous studies have suggested that I-EPF exhibits clinical and histological differences distinct from other variants, including classic EPF. Herein, we report two patients with I-EPF treated with topical indomethacin. These two cases exhibited less perifollicular and more perivascular eosinophilic infiltration, which is different in distribution from that of classic EPF. Immunohistochemical study demonstrated that the infiltrating mononuclear cells were CD4-dominant T cells in classic EPF and I-EPF, whereas the number of CD68-positive cells was significantly higher in classic EPF than in I-EPF. Immunohistochemical staining was also performed for eosinophilic pustular folliculitis (HPGDS), which has been reported to induce eosinophils and is a therapeutic target of indomethacin in classic EPF. HPGDS-positive cells were also observed in I-EPF, which may explain the effectiveness of topical indomethacin. Although clinical and histopathological features of I-EPF are different from other variants, the arachidonic acid pathway could be involved in eosinophil infiltration, not only in classic EPF but also in I-EPF.

Abstract
Immunosuppressive therapies can affect the immune response to or safety of vaccination in patients with inflammatory bowel disease (IBD). The appropriateness of vaccination should be assessed prior to the initiation of IBD treatment because patients with IBD frequently undergo continuous treatment with immunosuppressive drugs. This consensus was developed to support the decision-making process regarding appropriate vaccination for pediatric and adult patients with IBD and physicians by providing critical information according to the published literature and expert consensus about vaccine-preventable diseases (VPDs) [excluding cervical cancer and coronavirus disease 2019 (COVID-19)] in Japan. This consensus includes 19 important clinical questions (CQs) on the following 4 topics: VPDs (6 CQs), live attenuated vaccines (2 CQs), inactivated vaccines (6 CQs), and vaccination for pregnancy, childbirth, and breastfeeding (5 CQs). These topics and CQs were selected under unified consensus by the members of a committee on intractable diseases with support by a Health and Labour Sciences Research Grant. Physicians should provide necessary information on VPDs to their patients with IBD and carefully manage these patients' IBD if various risk factors for the development or worsening of VPDs are present. This consensus will facilitate informed and shared decision-making in daily IBD clinical practice.

Abstract
STXBP2, encoding syntaxin-binding protein 2, is involved in intracellular organelle trafficking and is associated with familial hemophagocytic lymphohistiocytosis type 5. Although STXBP2 mutations reportedly cause monogenic inflammatory bowel disease, the clinical course and underlying pathogenic mechanisms remain unclear. We identified a novel mutation in STXBP2 [c.1197delC, p.Ala400fs] in a boy with congenital intractable diarrhea and hemophagocytic lymphohistiocytosis (HLH). HLH was treated with intravenous prednisolone, cyclosporine, and dexamethasone palmitate. Hematopoietic stem cell transplantation (HSCT) along with prophylaxis for graft-versus-host-disease was performed at 5 months of age. Additionally, colonoscopies done before and after HSCT showed mild colitis with cryptitis. The patient showed elevated fecal calprotectin levels and persistent diarrhea even after HSCT and required partial parenteral nutrition. While anti-inflammatory treatment reduced diarrhea, it was not completely normalized even after HSCT, suggesting that the pathogenesis of inflammatory bowel disease associated with STXBP2 mutations involves both hyperinflammation and functional epithelial barrier defects.

Abstract
Background/Aims Very early-onset inflammatory bowel disease (VEO-IBD), defined as IBD diagnosed in patients younger than 6 years, is a challenge for pediatric gastroenterologists. Although there have been reports regarding VEO-IBD in Western countries, those in Asia are still lacking. This study aimed to investigate the clinical features of Japanese VEO-IBD patients. Methods Patients with VEO-IBD diagnosed between 2006 and 2019 were evaluated retrospectively. The disease phenotypes were classified into ulcerative colitis type (UC-type) and Crohn's disease type (CD-type), and the clinical features and courses were compared between the phenotypes. Results Overall, 54 VEO-IBD patients (19 patients with UC-type and 35 patients with CD-type) were evaluated. The median age at onset was 18 months. One patient had severe combined immunodeficiency (SCID), and 9 patients had monogenic IBD. Monogenic IBD was more prevalent in the CD-type patients with perianal disease (CD-type (PD)). The age at onset was significantly lower in the CD-type group (P<0.05). The most common initial symptom was bloody stools (70%), followed by diarrhea (63%), weight loss (24%), fever (20%), and perianal disease (20%). Excluding patients with SCID and monogenic IBD, 23 out of 44 patients (52%) required biologics. The biologics were switched in 11 out of 44 patients (25%), and the majority of these patients (82%) were in the CD-type group. Overall, 9 patients (20%) required intestinal resection or ostomy placement. Conclusions CD-type tends to occur at an earlier age, and monogenic IBD occurs significantly more frequently in CD-type (PD). Disease severity and treatment should be individualized, owing to the disease heterogeneity.

Abstract
Ectopic ovary is a rare gynaecological condition that results in problems with menstruation and pregnancy and may develop into a malignant tumour. However, as the condition is often asymptomatic, diagnosis is difficult and frequently delayed. We report a case of a 42-year-old female who presented with a 10-day history of abdominal pain. The patient underwent surgery that confirmed the diagnosis of an ectopic ovary with an internal abscess. The findings of our study indicate that ectopic ovaries can present with an abscess. Ectopic ovaries should be included in the differential diagnosis of masses with internal abscesses.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (CSCC) is one of the most common skin cancers. Prognosis is favorable following surgical resection of early-stage disease, but the management of the metastatic disease is challenging. Several prognostic risk factors have been described in the American Joint Committee on Cancer/the Union for International Cancer Control (UICC) 8th edition staging and the Brigham and Women's Hospital T classification system. However, their clinical validity in Asian populations is unclear because of racial differences in the clinical characteristics of CSCC. This study aimed to identify factors that could predict lymph node metastasis in Asian patients. METHODS This retrospective single-center study evaluated 540 patients with primary CSCC between 1989 and 2013. Five factors were evaluated for their ability to predict lymph node metastasis: maximum tumor diameter, tumor thickness, depth of invasion, degree of differentiation, and infiltrative growth pattern (INF). RESULTS Tumor diameter > 2 cm (p < 0.0001), tumor thickness > 6 mm (p < 0.0001), invasion beyond the subcutaneous fat (p < 0.0001), poor differentiation (p = 0.042), and INFc infiltration (p < 0.0001) were associated with lymph node metastasis in the univariate analyses. In the multivariate analysis, lymph node metastasis was independently associated with tumor size > 2 cm [hazard ratio (HR) 2.9, 95% confidence interval (CI) 1.4-6.2; p = 0.006], tumor thickness > 6.0 mm (HR 2.9, 95% CI 1.3-6.4; p = 0.007), and invasion beyond the subcutaneous fat (HR 2.3, 95% CI 1.0-5.1; p = 0.045). CONCLUSION Larger tumor diameter, greater tumor thickness, and deeper invasion included in the UICC T classification system are associated with increased risks of lymph node metastasis from CSCC in Japanese patients.

Abstract
Botryomycosis is a rare chronic suppurative granulomatous infection caused by several genera of non-filamentous bacteria. The clinical and histopathological findings are similar to those of mycetoma caused by true fungi or aerobic actinomycetes. Botryomycosis is divided into cutaneous and visceral disease, with the cutaneous form being more common. Histopathology shows granules of etiologic bacteria called "sulfur granules". Botryomycosis occurs more commonly among immunocompromised patients, although some cases have also been reported in immunocompetent patients. We report the case of an 8-year-old immunocompetent boy who visited our hospital with a 4-mm diameter subcutaneous tumor with mild tenderness on his right heel for several months. We surgically removed the tumor with an initial diagnosis of epidermal cyst. Histopathology showed sulfur granules surrounded by an eosinophilic matrix, indicating the Splendore-Hoeppli phenomenon. The granules consisted of Gram-positive cocci, leading to a diagnosis of botryomycosis. The patient was successfully treated by excision and oral trimethoprim/sulfamethoxazole (240 mg b.i.d.) for 2 weeks as adjuvant therapy. No recurrence was noted following treatment. The subcutaneous tumor in this case was smaller than the typical in botryomycosis infections. We reviewed the infection duration and tumor size in reported cases of botryomycosis in immunocompetent patients. Small tumor size may suggest that the case is in an early stage; therefore, it is important to remove and investigate these lesions proactively.

Abstract
Keratin-associated protein 8.1 (KAP8.1) is a hair protein whose structure, biochemical roles, and protein distribution patterns have not been well characterized. In this study, we generated a monoclonal antibody against human KAP8.1 to analyze the protein's roles and distribution in the human hair shaft. Using this antibody, we revealed that KAP8.1 was predominantly expressed in discrete regions of the keratinizing zone of the hair shaft cortex. The protein expression patterns paralleled the distribution of KAP8.1 mRNA and suggested that KAP8.1 plays a role associated with cells to control hair curvature. Cross-reactivity among species and epitope analysis indicated that the monoclonal antibody recognized a linear epitope shared among human, mouse, and sheep KAP8.1. The antibody failed to interact with sheep KAP8.1 in native conformation, suggesting that structural features of KAP8.1 vary among species.

Abstract
We report a case of a 59-year-old woman who was diagnosed with gastric and small intestinal anisakiasis, which was successfully treated with endoscopic extraction and Gastrografin therapy. She was admitted to our hospital with epigastric pain and vomiting one day after eating raw fish. She exhibited tenderness in the epigastrium without obvious rebound tenderness or guarding. Computed tomography (CT) demonstrated segmental edema of the intestinal wall with proximal dilatation and a small number of ascites. Because enteric anisakiasis was suspected based on the patient’s history of recent raw fish consumption and abdominal CT, we performed gastroscopy and confirmed that nine Anisakis larvae were attached to the gastric mucosa. All of the Anisakis larvae were extracted via endoscopy, and the patient was diagnosed with gastric and enteric anisakiasis. Additionally, in the hospital, we performed ileography twice using Gastrografin, which led to shortened hospital stay. Based on the clinical results of this case, we suggest that Gastrografin therapy is a safe, convenient, and useful method to extract enteric Anisakis larvae.

Abstract
Tie-over bolster dressing after skin grafting can prolong operative time, and cause hematoma and seroma formation because of uneven pressure application. To describe the possibility of discontinuing the use of tie-over dressing, we carried out a retrospective comparative study of patients who underwent skin grafting at an institution between January 2009 and December 2014. We investigated and compared the take rate, healing period, wound infection rate and hematoma formation rate for the tie-over dressing group and the non-tie-over dressing group. Among 266 patients, 148 and 118 patients were included in the tie-over dressing group and non-tie-over dressing group, respectively. There were no significant differences between the take rate, healing period, wound infection rate and hematoma formation rate for the two groups. Multivariate analysis showed that the complete graft take rate was not significantly influenced by tie-over dressing, age, sex, graft site, graft procedure and skin graft diameter. Although the use of tie-over dressing might remain necessary on sites with a free margin, including the eyelids, lips or nostrils, because of the difficulty in using tape fixation, the present study showed that alternative dressing with polyurethane foam is also useful in most cases of skin grafting.

Abstract
BACKGROUND Circulating microRNAs (miRNAs) are attracting major interest as potential non-invasive biomarkers for colorectal cancer (CRC). This study aimed to identify a novel serum miRNA biomarker for the early detection and/or evaluating prognosis of CRC patients. PATIENTS AND METHODS Comprehensive miRNA array analysis was carried out using serum samples from patients with colorectal neoplasia and healthy controls. Next, to verify whether the candidate miRNA possessed a secretory potential, we screened miRNA expression levels in culture medium from 2 CRC cell lines, followed by serum analysis from 12 stage IV CRC, 12 adenoma, and 12 control subjects. Thereafter, we validated expression of candidate miRNAs in 179 primary CRC tissues, as well as serum samples from an independent cohort of 211 CRCs, 56 adenomas, and 57 control subjects. RESULTS Through microarray analysis, we identified significantly higher levels of miRNA-1290 (miR-1290) in serum from patients with colorectal adenomas and cancers. We verified miR-1290 overexpression in serum of CRC patients in a training cohort. In the validation cohort, serum miR-1290 levels were significantly up-regulated in patients with colorectal adenomas (P < 0.0001) and cancers (P < 0.0001). Serum miR-1290 levels could robustly distinguish adenoma [area under the curve (AUC) = 0.718] and CRC patients (AUC = 0.830) from normal subjects. High miR-1290 expression in serum and tissue was significantly associated with tumor aggressiveness and poor prognosis. Moreover, serum miR-1290 levels were an independent prognostic factor [hazard ratio (HR) = 4.51; 95% confidence interval (CI) = 1.23-23.69; P = 0.0096] and an independent predictor for tumor recurrence (hazard ratio = 3.92; 95% confidence interval = 1.11-25.14; P = 0.032) in CRC. CONCLUSIONS Serum miR-1290 is a novel biomarker for early detection, recurrence, and prognosis in CRC.

Abstract
BACKGROUND Clinical T1 gastric cancer has low metastatic potential to lymph nodes and is generally curable by local treatment. Endoscopic resection can preserve the whole stomach and does not impair the patient's quality of life; however, its indication is strictly limited to the subset of patients without nodal metastasis. The study was designed to predict reliably the patients without nodal metastasis based only on the clinical information. METHODS We examined patients with clinical T1 disease who were treated with surgery. The clinically available information was evaluated for its ability to predict nodal metastasis by logistic regression model. Then, the predictive ability of the logistic regression model using the risk factors for nodal metastasis was evaluated by a receiver operating characteristic curve. RESULTS A total of 511 patients were entered into this study. The clinical depth (cT1a or cT1b), maximal tumor diameter, and pathological type were confirmed to be significantly different between patients with and without nodal metastasis. The cutoff value of the tumor diameter differed depending on the histology and clinical depth: 79 mm for differentiated type and 48 mm for undifferentiated type in cT1a tumors, and 43 mm for differentiated type and 11 mm for undifferentiated type in cT1b tumors. According to these criteria, 348 of the 511 patients (68.1 %) were classified to have predictive N0 status. The negative predictive value was 95.7 % (95 % confidence interval 94.0-97.5 %). CONCLUSIONS The predictive criteria based on the multivariate logistic model identified that almost two-thirds of the patients with clinical T1 gastric cancer were possible candidates for endoscopic treatment.

Abstract
Improper processing and storage of raw milk contaminated with Staphylococcus aureus at elevated temperatures can result in the production of staphylococcal enterotoxins, especially type A (SEA), which is most frequently associated with food poisoning outbreaks such as the large one in Osaka, Japan, in 2000. In this study, the characteristics of S. aureus growth and SEA production at various high temperatures in raw milk samples were studied using two raw milk samples naturally containing low and high levels of natural microflora. The optimal temperatures found for SEA production in the two milk types were as high as 40 and 44°C (range, 36 to 48°C), and SEA production was dependent on the initial dose of S. aureus. These high temperatures were close to that of the outbreak in Japan. Thus, it was concluded that temperature was critical for SEA production in raw milk. It was also observed that natural microflora in the milk samples considerably suppressed SEA production but not staphylococcal growth. On the other hand, the amount of toxin in most milk samples decreased after peaking during storage.

Abstract
BACKGROUND T1 gastric cancer can be diagnosed only by endoscopy and is almost curable by local treatment. It has been unclear how a multidetector-row computed tomography (CT) evaluation is valuable for clinical T1 patients. METHODS Patients with clinical T1 disease, as diagnosed by endoscopy and treated with endoscopic submucosal dissection (ESD) or surgery between October 2000 and October 2007, were examined. The efficacy of CT was evaluated by the reversal rate of endoscopic T1 by CT, the incidence of clinical M1 disease, and the accuracy of diagnosing pathological N+ disease in patients who received surgery. To confirm metachronous distant and nodal metastases, the disease-free survival (DFS) also was evaluated. RESULTS A total of 761 patients, 236 treated by ESD and 525 treated with surgery, were examined. None of the patients had an endoscopic diagnosis of clinical T1 reversed by CT. No clinical M1 disease was found. Among the 525 patients who underwent surgery, 8 showed clinical N+ disease (1.5 %), while 47 demonstrated pathological N+ disease (8.9 %). The accuracy, sensitivity, specificity, positive predictive value, and negative predictive values were 90.3, 4.3, 98.7, 25, and 91.3 %, respectively. The 5-year DFS rate was 93.6 % (95 % confidence interval 91.4-95.8 %). CONCLUSIONS The present study suggests that diagnostic value of CT is limited for staging of clinical T1 gastric cancer patients, because the reversal rate of endoscopic T1 by CT was very low, clinical M1 disease was rare, the diagnosis of N+ status was unreliable, and metachronous M1 and N+ findings were rare.

Abstract
Pure hair and nail ectodermal dysplasia (PHNED) is a rare genetic disorder characterized by hypotrichosis or complete alopecia, as well as nail dystrophy. Mutations in the type II hair keratin gene KRT85 and the HOXC13 gene on chromosome 12q have recently been identified in families with autosomal-recessive PHNED. In the present study, we have analyzed a consanguineous Syrian family with an affected girl having complete alopecia and nail dystrophy since birth. The family clearly showed linkage to chromosome 12q13.13-12q14.3, which excluded the KRT85 gene. Sequencing of another candidate gene HOXC13 within the linkage interval identified a homozygous frameshift mutation (c.355delC; p.Leu119Trpfs*20). Expression studies in cultured cells revealed that the mutant HOXC13 protein mislocalized within the cytoplasm, and failed to upregulate the promoter activities of its target genes. Our results strongly suggest crucial roles of the HOXC13 gene in the development of hair and nails in humans.

Abstract
BACKGROUND Hypohidrotic ectodermal dysplasia (HED) is a rare condition characterized by hypotrichosis, hypohidrosis and hypodontia. A de novo heterozygous mutation in the tumour necrosis factor receptor-associated factor 6 gene (TRAF6) was recently identified in a patient with HED, while functional consequences resulting from the mutation remained unknown. OBJECTIVES To determine the mechanism by which the TRAF6 mutation results in HED. METHODS We performed coimmunoprecipitation (co-IP) studies to determine whether the mutation would affect the interaction of TRAF6 with transforming growth factor β-activated kinase 1 (TAK1), TAK1-binding protein 2 (TAB 2) and ectodysplasin-A receptor-associated death domain protein (EDARADD). We then performed co-IP and glutathione S-transferase-pulldown assays to determine the TRAF6 binding sequences in EDARADD. In addition, we analysed the effect of the mutant TRAF6 protein on the affinity between wild-type TRAF6 and EDARADD, as well as on EDARADD-mediated nuclear factor (NF)-κB activation. RESULTS The mutant TRAF6 protein was capable of forming a complex with TAK1 and TAB 2 in a similar way to wild-type TRAF6. However, the mutant TRAF6 protein completely lost the affinity to EDARADD, while the wild-type TRAF6 bound to the N-terminal domain of EDARADD. Furthermore, the mutant TRAF6 inhibited the interaction between the wild-type TRAF6 and EDARADD, and also potentially reduced the EDARADD-mediated NF-κB activity. CONCLUSIONS We conclude that the mutant TRAF6 protein shows a dominant negative effect against the wild-type TRAF6 protein, which is predicted to affect the EDARADD-mediated activation of NF-κB during the development of ectoderm-derived organs, and to lead to the HED phenotype.

Abstract
BACKGROUND Clouston syndrome is a rare autosomal dominant condition characterized by hypotrichosis, nail dystrophy, and occasionally palmoplantar keratoderma. The disease is caused by mutations in GJB6 gene, which encodes a gap junction protein connexin 30 (Cx30). OBJECTIVE To disclose the molecular basis of Clouston syndrome in a Lebanese-German family, and also to determine precise expression of Cx30 in normal skin of humans and mice, as well as transcriptional regulation for the GJB6 expression. METHODS We searched for mutations in the GJB6 gene using DNA of the family members with Clouston syndrome. We performed immunostaining to localize the Cx30 expression in normal human skin and mouse embryos. In addition, we did a series of in vitro studies to investigate if the GJB6 could be a direct transcriptional target gene of p63. RESULTS We identified a recurrent heterozygous mutation c.31G>C (p.Gly11Arg) in the GJB6 gene in the Lebanese-German family with Clouston syndrome. Immunostaining in normal human skin sections demonstrated predominant expression of Cx30 in hair follicles, nails, and palmoplantar epidermis, which partially overlapped with p63 expression. We also showed co-expression of Cx30 and p63 in developing mouse hair follicles and nail units. In cultured cells, the GJB6 expression was significantly upregulated by ΔNp63α isoform. Further in vitro analyses suggested that ΔNp63α was potentially involved in the GJB6 expression via binding to the sequences in intron 1 of the GJB6 gene. CONCLUSION Our data further underscore the crucial roles of Cx30 in morphogenesis and development of skin and its appendages.

Abstract
Generalized pustular psoriasis (GPP) is a rare, potentially life threatening, and aggressive form of psoriasis, which is characterized by sudden onset with repeated episodic skin inflammation leading to pustule formation. Familial GPP is known to be caused by recessively inherited mutations in the IL36RN gene, which encodes interleukin 36 receptor antagonist (IL-36Ra). In this article, we performed mutation analysis of the IL36RN gene in 14 Japanese patients with GPP, and identified mutations in two of these patients analyzed. One patient was compound heterozygous for mutations c.115+6T>C and c.368C>G (p.Thr123Arg), whereas the other carried compound heterozygous mutations c.28C>T (p.Arg10*) and c.115+6T>C in the IL36RN gene. Expression studies using total RNA from the patients' skin revealed that the mutation c.115+6T>C resulted in skipping of exon 3, leading to a frameshift and a premature termination codon (p.Arg10Argfs*1). The protein structure analysis suggested that the missense mutation p.Thr123Arg caused misfolding and instability of IL-36Ra protein. In vitro studies in cultured cells showed impaired expression of the p.Thr123Arg mutant IL-36Ra protein, which failed to antagonize the IL-36 signaling pathway. Our data further underscore the critical role of IL36RN in pathogenesis of GPP.

Abstract
BACKGROUND H syndrome is a rare autosomal recessive genetic disorder which involves the skin and other systemic organs and is caused by mutations in the SLC29A3 gene. OBJECTIVES To disclose the molecular basis of H syndrome in two Syrian families, and to determine the localization of hENT3 in human skin. METHODS DNA from two Syrian families with H syndrome was analyzed through direct sequencing, and the expression of hENT3 in normal human skin was investigated by in situ hybridization and immunostaining. RESULTS We identified two novel mutations in the SLC29A3 gene: a homozygous splice site mutation IVS1+2T>G predicted to cause a splicing error, and a homozygous missense mutation c.1157G>A (p.R386Q) which substituted highly conserved amino acid residue in a transmembrane domain of hENT3. Furthermore, we demonstrate that hENT3 is expressed in histiocytes as well as in endothelium of blood and lymphatic vessels in normal human skin. CONCLUSIONS Our results further enhance the mutation spectrum of the SLC29A3 gene for this rare genetic disorder, and also suggest potential pathomechanisms for the skin lesions resulting from SLC29A3 mutations.

Abstract
442 Background: CXCL5 is known as CXC chemokine which promotes angiogenesis related to cancer. However, the function of serum level of CXCL5 (sCXCL5) has not been fully studied in colorectal cancer. The purpose of this study was to evaluate the relationships between preoperative sCXCL5 and clinicopathological features and prognosis in colorectal cancer. Methods: This was a single-institution, retrospective study. Preoperative serum samples of 250 colorectal cancer patients (between 1998 and 2007, median age: 65.3 years, male 159/female 91) were available for the study, and 33 normal serum was examined and used as a control. sCXCL5 level was assayed using a commercially available enzyme-linked immunosorbent assay kit, and analyzed statistically. Results: Mean level of sCXCL5 was significantly higher in colorectal cancer patients than in control group (p=0.013). Patients with liver metastases had significantly higher sCXCL5 level than those without metastases (p=0.0086), and in logistic analysis, sCXCL5 was an independent marker for predicting liver metastasis (p=0.040). Overall survival of patients with elevated sCXCL5 level was significantly worse than those with lower sCXCL5 (p=0.0006). Conclusions: Preoperative sCXCL5 level was increased in colorectal cancer patients compared to in healthy volunteer and elevated sCXCL5 was correlated with liver metastasis and poor prognosis for overall survival in colorectal cancer patients. Elevated sCXCL5 has been proposed as a useful predictive marker for liver metastasis and overall survival in colorectal cancer. No significant financial relationships to disclose.

Abstract
424 Background: Colorectal cancer (CRC) is one of the major causes of cancer death worldwide. In CRC, serum levels of CEA have become well-established prognostic indicators. However, it is not generally accepted as optimal in its prognostic power. The aim of this study was to identify novel and reliable serum prognostic markers. Methods: We performed cytokine array to identify novel prognostic serum marker, and CXCL16 was selected. To investigate the relationships between sCXCL16 and clinicopathological findings including survival, the serum levels of CXCL16 in 237 CRC patients and 20 normal volunteers were assessed by enzyme-linked immunosorbent assay. Furthermore, we investigated proliferation, invasion and wound healing assay to investigate the biological role of CXCL16 to colon cancer cell by recombinant CXCL16 exposing to HT-29. Results: The mean sCXCL16 concentration in patients was significantly higher than that in normal volunteers (p<0.0001). In addition, sCXCL16 levels increased significantly in accordance with the progression of UICC stage classification (p < 0.05). In clinicopathologic findings, sCXCL16 was significantly associated with the presence of lymph node (p=0.019) and the presence of liver metastases (p=0.011). Elevated sCXCL16 level demonstrated a significant association with poor survival, and was an independent risk factor for poor survival. Furthermore, sCXCL16 was an independent marker for predicting liver metastasis (logistic analysis; p=0.0015). In vitro, recombinant CXCL16 promoted epithelial mesencymal transition (EMT) phenotype characterized by impaired E-cadherin and induction of Vimentin. In addition, CXCL16 promoted cell growth, migration and invasion. Conclusions: Our data demonstrate that preoperative sCXCL16 level increased in colorectal cancer patients, and that sCXCL16 correlated with liver metastasis, and is an independent prognostic factor for overall survival. Elevated CXCL16 has been proposed as a useful predictive marker for liver metastasis and overall survival in CRC. In vitro, CXCL16/CXCR6 axis might play an importance role in mediating cell survival, migration and invasion by EMT in CRC cell. No significant financial relationships to disclose.

Abstract
40 Background: Epithelial mesencymal transition (EMT) promotes facilitates migration and invasion of epithelial tumour cells. EMT is induced by growth factors implicated in theses process such as hepatocyte growth factor (HGF). Our aim of this study is whether HGF/c-Met pathway is associated with metastasis of gastric cancer (GC), especially in peritoneal dissemination (PD). Methods: HGF and c-Met expression and EMT related molecules were evaluated using real-time PCR and immunohistochemistry in GC tissues. The role of HGF/c-Met pathway for EMT and anoikis was determined and c-Met TKI (SU11274) was tested for their ability to block HGF-induced biological effects in vitro and vivo. Results: In HGF(-)c-Met(+) GC cells,recombinant HGF promoted EMT phenotype characterized by morphology, impaired E-cadherin and induction of Vimentin. HGF promoted cell growth, invasiveness, migration ability and inhibition of anoikis. SU11274 blocked HGF-induced EMT and the biological effects in vitro. In contrast of HGF(+)c-Met(+) GC cells, HGF exposure was not affected biological outcome of EMT and anoikis but SU11274 blocked biological effect as same as in HGF(-)c-Met(+) GC cells. In vivo, HGF(+)c-Met(+) GC cell line only established PD and SU11274 intraperitoneally caused an inhibition of PD growth. Clinically, HGF expression was significantly positive correlated with c-Met expression in GC specimens. Increased HGF and c-Met demonstrated a significantly associated with poor prognosis and can predict PD, respectively. Furthermore, HGF was one of the independent factors for predicting PD. Immunohistochemical analysis showed HGF and c-Met were predominantly co-expressed in cancer cell of both primary GC and PD. Conclusions: We have demonstrated that HGF/c-Met pathway as an inducer of EMT and anoikis inhibition in GC cell. Co-expression of HGF and c-Met implicates its potential to promote PD in GC. Blocking the autocrine HGF/c-Met pathway may be clinically useful for the treatment of PD in GC. No significant financial relationships to disclose.

Abstract
AIMS The mechanism of distant recurrence in rectal cancer after preoperative chemoradiotherapy (CRT) has yet to be fully elucidated. Further improvements in survival rates cannot be achieved without decreasing distant recurrence after preoperative CRT. Recently, it was reported that hypoxic conditions were correlated with cancer stem cell generation. Therefore, we investigated the correlation between the expression of CD133 and hypoxia inducible factor-1α (HIF-1α), and their association with clinical outcome. MATERIALS AND METHODS Fifty-two patients with rectal cancer underwent preoperative CRT. Residual cancer cells after CRT were obtained from formalin-fixed paraffin-embedded specimens using micro-dissection. The expression levels of CD133 (PROM1) and HIF-1α genes were measured using real-time reverse transcription polymerase chain reaction. The correlation between expression and irradiation was evaluated using colon cancer cell lines. Immunohistochemical staining of these proteins after CRT was also investigated. RESULTS We observed a significant inverse correlation between the gene expression of CD133 (PROM1) and HIF-1α genes in residual cancer cells after CRT. Elevated CD133 gene expression was associated with distant recurrence and poor recurrence-free survival. Elevated HIF-1α gene expression was associated with poor overall survival. In vitro, the change in gene expression levels after irradiation showed inverse patterns. Immunohistochemical analyses showed that residual cancer cells strongly expressed CD133 and lacked HIF-1α expression. CONCLUSION Our results suggest that CD133 and HIF-1α expression is associated with tumour re-growth and distant recurrence after CRT. These results may assist in clarifying the development of future cancer therapeutics in rectal cancer patients undergoing preoperative CRT.

Abstract
A rare case of myotonic dystrophy (MD) with congestive heart failure, associated with QT prolongation and torsade de pointes (TdP) is reported. A 53-year-old woman was admitted to the hospital because of congestive heart failure. Electrocardiograph (ECG) showed first-degree atrioventricular block and QT prolongation. During hospitalization, TdP appeared but returned to sinus rhythm spontaneously. As the patient had quadriplegia, a myopathic face, cataracts, diabetes mellitus, and an increased number of cytosine-thymineguanine (CTG) repeats (760 repeats), she was diagnosed as having MD. Electrocardiographic analysis of her family also revealed abnormal QT(U) prolongation in her daughter and brother who both had MD, while ECG findings of other family members without MD were normal. Thus, the presence of QT(U) prolongation was associated with MD in this family.
