Abstract
STUDY QUESTION Is oocyte cryopreservation an applicable option for fertility preservation in unmarried patients with haematological malignancies? SUMMARY ANSWER Oocyte cryopreservation via the vitrification method is accessible and may be considered an option for fertility preservation in unmarried patients with haematological malignancies. WHAT IS KNOWN ALREADY Haematological malignancies are most commonly observed amongst adolescent and young adult women. Although the survival rate and life expectancy of those with haematological malignancies have improved, chemotherapy and radiotherapy may impair their reproductive potential. Oocyte cryopreservation is thus an ideal option to preserve their fertility. STUDY DESIGN SIZE DURATION This study retrospectively evaluated 193 unmarried patients (age: 26.2 ± 0.4 years) with haematological malignancies, who consulted for oocyte cryopreservation across 20 different fertility centres in Japan between February 2007 and January 2015. The primary outcome measures were the oocyte retrievals and oocyte cryopreservation outcomes. The secondary outcome measures were the outcomes following oocyte warming for IVF. PARTICIPANTS/MATERIALS SETTING METHODS The patients had commenced ovarian stimulation cycles via antagonist, agonist, natural and minimal methods for oocyte retrievals, defined according to the treatment strategy of each respective fertility centre. A vitrification method using the Cryotop safety kit was used for oocyte cryopreservation. ICSIs were used for insemination of warmed oocytes. The endometrial preparation method for embryo transfer was hormonal replacement therapy, except in the case of a patient who underwent a spontaneous ovulatory cycle. MAIN RESULTS AND THE ROLE OF CHANCE Among 193 patients, acute myeloid leukaemia (n = 45, 23.3%) was most common, followed by acute lymphoid leukaemia (n = 38, 19.7%) and Hodgkin's lymphoma (n = 30, 15.5%). In total, 162 patients (83.9%) underwent oocyte retrieval, and oocytes were successfully cryopreserved for 155 patients (80.3%). The mean number of oocyte retrieval cycles and cryopreserved oocytes were 1.7 ± 0.2 and 6.3 ± 0.4, respectively. As of December 2019, 14 patients (9.2%) had requested oocyte warming for IVF. The survival rate of oocytes after vitrification-warming was 85.2% (75/88). The rates of fertilisation and embryo development were 80.0% (60/75) and 46.7% (28/60), respectively. Ten patients (71.4%) had successful embryo transfers, and seven live births (50.0%) were achieved. LIMITATIONS REASONS FOR CAUTION This study was limited by its retrospective nature. Additionally, there remains an insufficient number of cases regarding the warming of vitrified oocytes to reliably conclude whether oocyte cryopreservation is effective for patients with haematological malignancies. Further long-term follow-up study is required. WIDER IMPLICATIONS OF THE FINDINGS Oocyte retrieval and oocyte cryopreservation were accessible for patients with haematological malignancies; however, the number of oocyte retrievals may have been limited due to the initiation of cancer treatments. Acceptable embryonic and pregnancy outcomes could be achieved following oocyte warming; therefore, our results suggest that oocyte cryopreservation can be considered an option for fertility preservation in patients with haematological malignancies.

Abstract
BACKGROUND/AIMS Three-dimensional CT has become an essential tool for successful hepatic surgery. Up to now, efforts have been made to simultaneously visualize hepatic vasculature and bile ducts. Herein, we introduce a new one-stop shop approach to hepatic 3D-anatomy, using a standard enhanced MDCT alone. METHODOLOGY A 3D-reconstruction of hepatic vasculature was made using data from contrast enhanced MDCT and SYNAPSE VINCENT software. We identified bile ducts from axial 2D image, and then reconstructed the 3D image. Both hepatic vasculature and bile duct images were integrated into a single image and it was compared with the 3D image, utilized with MRCP or DIC-CT. RESULTS The first branches of both the right and left hepatic ducts were hand-traced and visualized for all 100 cases. The second branches of these ducts were visualized in 69 cases, and only the right second branch was recognized in 52 cases. Anomalous variations of bile ducts, such as posterior branch joining into common hepatic duct, were recognized in 12 cases. These biliary tract variations were all confirmed by MRCP or DIC-CT. CONCLUSIONS Our new one-stop shop approach using the 3D imaging technique might contribute to successful hepatectomy as well as reduce medical costs and radiation exposure by omission of MRCP and DIC-CT.

Abstract
621 Background: Prognosis in patients with unresectable liver metastases from colorectal cancer is known to be very poor. However, thanks to progress of chemotherapy including molecular-target agents, “conversion” (from unresectable to resectable) has been sometimes seen. The aim of this preliminary study is to clarify the impact of FOLFOXIRI plus bevacizumab (Bev) on conversion and prognosis in patients with initially unresectable liver metastases from colorectal cancer. Methods: Seven patients with initially unresectable liver metastases from colorectal cancer, who received FOLFOXIRI (LOHP 85mg/m2 D1, CPT-11 150mg/m2 D1, LV 200mg/m2 D1, and 5FU 2,400mg/m2 infusion over 46 hours, D1) plus Bev 5mg/kg bolus every 2 weeks, were included in this study. Resectability, disease-free survival (DFS), and overall survival (OS) after hepatic resection were investigated in detail. In addition, completeness and adverse effects were examined in this regimen. Results: All 7 patients tolerated the regimen well, and no adverse effect of grade 3-4 was observed. Five out of 7 patients (71%) became resectable (conversion), except for 2 with multiple lung metastases and bone metastasis prior to chemotherapy. Our historical conversion rates were, 0% (0/7) in 5FU/LV regimen from 1994 to 2003, 25% (7/27) other regimens such as FOLFIRI and FOLFOX except for FOLFOXIRI plus Bev from 2004. In 5 patients who became resectable, CR was not observed, however, all had PR after 6 cycles of chemotherapy (RR 100%). All 5 patients could undergo curative (R0) hepatic resection, furthermore, all had pathological major response (grade 2). Follow-up period ranged from 8 to 18 months, with a median period of 14 months, and 2 patients relapsed (lung recurrence and peritoneal dissemination), and one died of lung metastases (1.5-year OS and DFS are 80 % and 60%). Conclusions: Our preliminary data suggested the feasibility of this new therapeutic combination in patients with initially unresectable liver metastases from colorectal cancer, and a high conversion rate and better prognosis.

Abstract
228 Background: In our clinical data, we had the interesting findings that the pathologic sinusoidal obstruction syndrome and serum hyaluronic acid after neoadjuvant oxaliplatin-associated chemotherapy for liver metastatic colorectal cancer with bevacitumab (Bev) was ameliorated compared to those without Bev. The purpose of this study was to investigate the influence of bevacizumab administration on regenerating liver in rat 70% and 90% hepatectomy (Hx) model as a surrogate model of human massive hepatectomy for liver metastatic colorectal cancer. Methods: Male Wister rats weighing 180-230g were divided into the following four groups: 70%Hx, 70%Hx + Bev, 90%Hx and 90%Hx+Bev group. The rats were pretreated with intraperitoneal administration of bevacizumab (5mg/kg) 7 days before hepatectomy. The remnant liver and blood samples were taken one day after hepatectomy, and the following parameters were evaluated: blood analysis (AST, ALT, LDH, T- Bil, and hyaluronic acid), liver weight to body weight (Lw/Bw) ratio, and postoperative survival rate for three days. Results: In the 70%Hx model, there was no significant difference between the 70%Hx group and 70%Hx + Bev group in blood analysis one day after hepatectomy; AST (1928 vs. 923 IU/L), ALT (1282 vs. 670 IU/L), T-Bil (0.17 vs. 0.19 mg/dl), LDH (3822 vs. 2967 U/L) and hyaluronic acid (995.7 vs. 1026.6 ng/ml) and in Lw/Bw ratio (1.78 vs. 1.84). In 90%Hx model, AST and ALT of blood analysis in 90%Hx+Bev group significantly decreased compared to those in 90%Hx group; AST (3428 vs. 4995 IU/L, P<0.05), ALT (1471 vs. 2287 IU/L, P<0.05), T-Bil (1.94 vs. 2.57 mg/dl), LDH (3229 vs. 5351 U/L) and hyaluronic acid (3865.7 vs. 7862.2 ng/ml). The Lw/Bw ratio in 90%Hx+Bev group significantly increased compared to that in 90%Hx group (0.80 vs. 0.67, P<0.05). The postoperative survival rate in 90%Hx+Bev group showed tendency to improve compared to that in 90%Hx group (75% vs. 50%, P=0.19). Conclusions: The administration of bevacizumab seven days before hepatectomy did not significantly affect the liver functions and liver regeneration rate. These findings suggest that hepatectomy might be safe and feasible after the use of bevacizumab. No significant financial relationships to disclose.

Abstract
230 Background: Histone deacetylase (HDAC) is strongly associated with epigenetic regulation and carcinogenesis, and its inhibitors induce the differentiation or apoptosis of cancer cells. Valproic acid (VPA) is one of the clinically available HDAC inhibitors. We previously showed that VPA augmented antitumor effect of GEM in choalngiocarcinoma cell line (2010 GI Symposium); this time, we performed microarray analysis and Ingenuity Pathways Analysis (IPA) to identify the systematic mechanism of the augmentative effect of VPA. Methods: Human cholangiocarcinoma cell line (HuCCT1) was used. The anticancer effects of VPA or gemcitabine (GEM), and the effects of VPA combined with GEM were studied by MTT assay. We divided the following four groups: control group, VPA group, GEM group, VPA plus GEM combination group. The gene expressions of p21, HDAC, VEGF, and HIF-1 were evaluated by RT-PCR. And, the microarray analysis was performed, the genes were picked up using Gene Spring GX10, and then IPA was performed. Results: In GEM alone group, no effect of GEM was observed in dose of 5 mm, and 16% of proliferation-inhibitory effects were observed in dose of 10 nm. In VPA alone group, no effect of VPA was observed in dose of 0.5 mm, and 12%, 35%, and 67% of proliferation-inhibitory effects were observed in dose of 1.0, 5.0, and 10mm, respectively. GEM (5 nm) and VPA (0.5 mm) reduced by 23%, which significantly augmented the anticancer effect of GEM alone or VPA alone (p<0.01). Furthermore, GEM combined with VPA upregulated the p21 expression compared with single agent (p<0.05). And, in regard to microarray analysis, we analyzed in 28,869 genes. The 24 genes were picked up with the comparison between VPA group and VPA plus GEM combination group using Gene Spring GX10, and the gene network of the cellular development containing the gene relevant to the differentiation of cancer cell, HLA-DR, was formed with IPA. Conclusions: VPA augmented the effects of anticancer agents in a cholangiocarcinoma cell line. Such effects may be owing to the gene network of the cellular development. HDAC inhibitor may have the effect of the differentiation of cancer cell. No significant financial relationships to disclose.

Abstract
219 Background: Histone deacetylase (HDAC) modulates gene expressions by chromatin remodeling during malignant transformation, and showed malignant behavior in intrahepatic cholangiocarcinoma (IHCC) (ASCO GI 2008). HDAC inhibitors have recently been found to repress the function of hypoxia inducible factors (HIF) through inducing hyperacetylation of histones. We also reported that the correlation between the expression of CD133, which was one of the cancer stem cell marker, and HIF-1α in IHCC (J Gastroenterol. 2010), and hypothesized that the cancer stem cell could be regulated by histone acetylation through the HIF-1α pathway. The aim of this study was to elucidate the potential mechanism of HDAC for the regulation of malignant behavior including the cancer stem cell in IHCC. Methods: Thirty-five patients with IHCC who underwent hepatic resection were evaluated. The expressions of HDAC1 (sc-6298 Santa Cruz Biotechnology, USA), HIF-1α (NB100-105 Novus Biologicals, USA) and CD133 (Ab27699 Abcam Inc, UK) were determined immunohistochemically, and the patients were divided into two groups: HDAC1 positive group (n=21); and negative group (n=14). Clinicopathological variables including HIF-1α and CD133 expressions were analyzed according to these expressions. Results: The HDAC1 expression correlated significantly with higher stage, lymph node metastasis, and vascular invasion. The prognosis in the HDAC1 positive group was poorer than in the HDAC1 negative group (5-year survival: 77.9% vs. 7.9%, p=0.001). In the multivariate analysis, HDAC1 positive expression was identified as the only independent prognostic factor for disease free survival (Hazard Ratio: 7.194, p=0.0018). There was a significant correlation between HDAC1 expression and HIF-1α expression (p=0.007), and also between HIF-1α expression and CD133 expression (p=0.10). Furthermore, co-expressions of these markers in same cancer cells were proven by immunofluorescent staining in the serial section. Conclusions: The findings suggested that histone acetylation regulated cancer stem cell through the HIF-1α pathway; therefore, HDAC1 might be a possible promising molecular target in IHCC. No significant financial relationships to disclose.

Abstract
OBJECTIVE The aim of this study was to investigate how interleukin (IL)-8 (cytokine-induced neutrophil chemoattractant; CINC-1) and monocyte chemotactic protein (MCP)-1/CCL2 contribute to root resorption during orthodontic tooth movement. MATERIALS AND METHODS Forty 6-week-old male Wistar rats were subjected to orthodontic force of 10 or 50 g to induce a mesially tipping movement of the upper first molars for 7 days. We determined the expressions of CINC-1, CXCR2, and MCP-1 proteins in root resorption area using immunohistochemistry. Furthermore, we investigated the effects of compression forces (CF) on IL-8 and MCP-1 production by human periodontal ligament (hPDL) cells. We observed an effect of chemokine treatment on rat odonto/osteoclasts in dentin slices that recapitulated root resorption. RESULTS The immunoreactivity for CINC-1/CXCR2 and MCP-1 was detected in odontoclasts and PDL fibroblasts by the orthodontic force of 50 g on day 7. CF increased the secretion and the expression of mRNA of IL-8 and MCP-1 from PDL cells in a magnitude-dependent manner. Moreover, CINC-1 and MCP-1 stimulated osteoclastogenesis from rat osteoclast precursor cells. CONCLUSION IL-8 (CINC-1) and MCP-1 may therefore facilitate the process of root resorption because of excessive orthodontic force.

Abstract
INTRODUCTION Previously, the authors have reported the acceleration of tooth movement and osteoclastogenesis on the pressure site in an experimental tooth movement model by low-energy laser irradiation (LELI), which stimulated the RANK/RANKL system and c-fms/macrophage colony-stimulating factor system. However, the effect of LELI on osteogenesis on the tension site is not known clearly. Moreover, the temporal changes in alveolar bone during tooth movement have not been investigated as yet. Therefore, the present study was designed to examine the effects of LELI on alveolar bone remodeling during experimental tooth movement, and observe the temporal bone mineral density (BMD) using micro-computed tomography (muCT). MATERIALS AND METHODS To induce experimental tooth movement in rats, 10 g force was applied to the upper right first molar with Nickel titanium closed-coil. Next, a gallium-aluminum-arsenide (Ga-Al-As) diode laser was used to irradiate the area around the moved tooth, and BMD and the amount of tooth movement were measured by muCT scanning for 21 days. Histopathological examination was also performed. RESULTS The amount of tooth movement in the LELI group was significantly greater than in the non-irradiation group by the end of the experimental period. Further, compared with the non-irradiation group, the fall of BMD was less in the LELI group. CONCLUSION These findings suggest that LELI accelerates the velocity of tooth movement via stimulation of the alveolar bone remodeling.

Abstract
e15056 Background: Oxaliplatin is now considered a standard treatment for advanced or unresectable colorectal cancer, but sensory neurotoxicity is its dose-limiting toxicity. The OPTIMOX (stop and go) approach offers a reasonable strategy, but preventive agent is not established. It is reported that Gosha-jinki-gan (a blended herbal medicine) is recently considered as an effective agent for the neurotoxicity of taxanes and for vibration sensation in patients with diabetic neuropathy. Patients and Methods: From 2007, 32 patients treated with modified FOLFOX6 for advanced or unresectable colorectal cancer were randomized. Fifteen patients received oral administration of 7.5 g/day of Gosha-jinki-gan (G group) every days from first course and 17 patients (Control group) did not. Neurotoxicities were evaluated every course according to DEB-NTC (Neurotoxicity Criteria of DEBIOPHARM) and NCI-CTCAE Ver.3.0 using self-check sheet. Results: The median number of cycles of per patient of G group was 14 (range, 4–26), and that of C Group was 9 (range, 1–20). Cumulative dose of oxaliplatin of two groups was 1,190 mg/m2 (G group) and 765 mg/m2 (C Group). Peripheral neurotoxicity evaluated by DEB-NTC in Group G was grade 0 in 0 patients (0%), grade 1 in 11 (73%), grade 2 in 4 (27%) and grade 3 in 0 (0%) and, in C group, respectively, 1 (6%), 6 (35%), 7 (41%), 3 (18%). According to NCI-CTCAE, neurotoxicity was lower in G group than that of C group. Fifteen patients in G group were evaluated by RECIST criteria with a PR rate of 66.7%, SD rate of 20.0% and PD rate of 13.3%. Seventeen patients in C group were evaluated by RECIST criteria with a PR rate of 52.9%, SD rate of 35.3% and disease control rate of 11.8%. Conclusion: Gosha-jinki-gan is effective for preventing oxaliplatin-induced neuropathy in advanced or unresectable colorectal cancer patients. [Table: see text]

Abstract
The membrane current in the Hodgkin-Huxley equations is considered to be a stimulus to the membrane and the responses to the simulus are numerically calculated. Responses of the Hodgkin-Huxley model to an alternating current superimposed upon a constant bias current show qualitative analogy to responses of biological mechanoreceptors. The intensity of the bias current seems to correspond to the degree of adaptation of actual receptors.

Abstract
Among young women, the incidence of uterine corpus cancer is increasing. Most young women can not preserve fertility because simple total hysterectomy with bilateral salpingo-oophorectomy is the standard method for early endometrial cancer so far. We present a case of early endometrial adenocarcinoma which succeeded in pregnancy and delivery after resectoscopic surgery. Following a circumferential resection of the lesion including the mucosa and muscle layer under resectoscopic guidance, the patient became pregnant by means of in vitro fertilization-embyo transfer with hormone replenishment. She underwent cesarean section at 33 weeks and five days of gestation and had a healthy baby. Resectscopic surgery can help to preserve fertility among young women who have early invasive endometrial cancer.

Abstract
OBJECTIVE Recent studies have demonstrated that low-energy laser irradiation stimulates bone formation in vitro and in vivo. However, very little is known about the effects of laser irradiation on osteoclastogenesis. The receptor activator of the nuclear factor-kB (RANK) / RANK ligand (RANKL) / osteoprotegerin (OPG) system is essential and sufficient for osteoclastogenesis. The present study was designed to examine the effects of low-energy laser irradiation on expressions of RANK, RANKL, and OPG during experimental tooth movement. DESIGN To induce experimental tooth movement in rats, 10 g of orthodontic force was applied to the molars. Next, a Ga-Al-As diode laser was used to irradiate the area around the moved tooth and the amount of tooth movement was measured for 7 days. Immunohistochemical staining with RANK, RANKL, and OPG was performed. Real time PCR was also performed to elucidate the expression of RANK in irradiated rat osteoclast precursor cells in vitro. RESULTS In the irradiation group, the amount of tooth movement was significantly greater than in the non-irradiation group by the end of the experimental period. Cells that showed positive immunoreactions to the primary antibodies of RANKL and RANK were significantly increased in the irradiation group on day 2 and 3, compared with the non-irradiation group. In contrast, the expression of OPG was not changed. Further, RANK expression in osteoclast precursor cells was detected at an early stage (day 2 and 3) in the irradiation group. CONCLUSION These findings suggest that low-energy laser irradiation stimulates the velocity of tooth movement via induction of RANK and RANKL.

Abstract
BACKGROUND It is well known that the prognosis for esophageal cancer is worse than for other digestive cancers in spite of multimodality treatment, and there is an urgent need to improve this situation. The epidermal growth factor receptor (EGFR) inhibitor, gefitinib, was approved in Japan to treat advanced non-small cell lung cancer patients and several papers have since reported that the successfully treated patients had genetic mutations in EGFR. PURPOSE The aim of this study was to investigate the existence of EGFR mutations in esophageal cancer cell lines and primary lesions, and also to explore the possibility of treating esophageal cancer using gefitinib. MATERIALS AND METHODS Nineteen esophageal cancer cell lines were cultured and DNA was extracted using an ultracentrifugation method. Fifty cases of primary cancer and corresponding normal tissue samples were obtained and DNA was extracted using the same protocol. Nested PCR and DNA sequencing targeting exons 18, 19, 20 and 21 of EGFR were performed to investigate the presence of mutations in esophageal cancer cell lines and primary tumors. RESULTS Three of the 19 cell lines had the same silent mutation at nucleotide 2607, a G-to-A substitution in exon 20. One of the 50 patients had an EGFR mutation in codon 719, resulting in an amino acid substitution from glycine to aspartic acid. CONCLUSION EGFR mutations in esophageal carcinoma are rare but do exist, and thus gefitinib could be included in esophageal cancer treatment regimens by selecting those patients who possess such mutations.

Abstract
BACKGROUND AND STUDY AIMS The Confocal Endomicroscopy System (Optiscan Pty Ltd. and Pentax Corp.) is a newly developed imaging tool that uses laser light and optical technology to visualize living tissue at the cellular level. Digital images of cells magnified 1000-fold appear in real time on a computer screen, which enables immediate detection of changes in cellular structure without the need for a biopsy. The aim of this study was to assess the features of the cellular architecture of cancerous tissue that can be used in the differential diagnosis of cancerous tissue and normal mucosa using this system's image-processing software. PATIENTS AND METHODS A total of 27 gastric cancers were examined ex vivo using confocal endomicroscopy. A fluorescent contrast agent, acriflavine, was applied topically to normal and to cancerous mucosa. In vivo imaging of the gastric mucosa after intravenous injection of fluorescein sodium was also performed in nine patients with gastritis or gastric cancer. RESULTS The nuclear area in the ex vivo specimens was calculated using Scion Image software. The mean nuclear area of cancer cells was found to be significantly larger than that of normal cells in 18/27 gastric cancers (67 %). The mean nuclear area of the cancers tended to be larger than that of normal mucosa, especially in cases of differentiated adenocarcinoma. In more than half the cases, it was possible to diagnose malignancy automatically using confocal endomicroscopy and image-processing software without the need for biopsy and pathological examination. In vivo imaging of cancerous lesions showed irregularity in cellularity and vascularity. CONCLUSION The ability of this imaging device to differentiate between normal tissue and cancerous tissues gives it potential value as a new screening tool for early detection of malignancy.

Abstract
BACKGROUND There is an increased incidence of rare imprinting disorders associated with assisted reproduction technologies (ARTs). The sex-specific epigenetic modifications that are imposed during gametogenesis act as a primary imprint to distinguish maternal and paternal alleles. The most likely candidate for the gametic mark is DNA methylation. However, the timing of DNA methylation acquisition in adult oocytogenesis and the effects of superovulation are unknown. METHODS We examined the maternal methylation of PEG1(MEST), LIT1(KCNQ1OT1) and ZAC(PLAGL1) and the paternal methylation of H19 in adult growing oocytes of humans and mice and compared them with the methylation status of mouse neonatal growing oocytes by using bisulphite sequencing. Furthermore, we examined the effects of superovulation in the human and mouse. RESULTS Maternal methylation of these genes has already been initiated to some extent in adult human and mouse non-growing oocytes but not in mouse neonates. In addition, the methylation dynamics during adult human and mouse oocyte development changed more gradually than those during neonatal oocyte development. Furthermore, we found the demethylation of PEG1 in growing oocytes from some ART-treated infertile women and a gain in the methylation of H19. We also detected methylation changes in superovulated mice. CONCLUSION Our studies in the human and mouse suggest that superovulation can lead to the production of oocytes without their correct primary imprint and highlight the need for more research into ARTs.

Abstract
The purpose of this study was to investigate the clinicopathological and biological significance of human carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) gene expression in human intrahepatic cholangiocarcinoma. CEACAM6 is reported to be involved in human malignancies. However, in cholangiocarcinoma expression of CEACAM6 and its clinicopathological significance have not been investigated. CEACAM6 expression status was determined and analysed with respect to various clinicopathological parameters in 23 intrahepatic cholangiocarcinomas. Additionally, we investigated effects of CEACAM6 gene in the cholangiocarcinoma cell lines. CEACAM6 gene expression in cancer tissues was higher than in noncancerous tissues in 16 of the 23 cases; however, it was not statistically significant. The tumours with elevated CEACAM6 expression showed a tendency to be associated with lymphatic invasion and stage of the disease. Interestingly, patients with high CEACAM6 expression showed a significantly poorer disease-free survival rate than those with low CEACAM6 expression. We demonstrated that CEACAM6-transfected cells were more proliferative, more invasive and more chemoresistant to gemcitabine compared to mock-transfected cells. Furthermore, CEACAM6 gene silencing by CEACAM6-specific siRNA resulted in higher chemosensitivity to gemcitabine. CEACAM6 is a potential prognostic indicator and potential chemoresistant marker to gemcitabine for patients with intrahepatic cholangiocarcinoma.

Abstract
Enhancer of zeste homologue 2 (EZH2), a member of the polycomb group protein family, plays a crucial role in the regulation of embryonic development and has been associated with the regulation of the cell cycle. Recently, several studies have shown that EZH2 is highly expressed in aggressive tumours, including human breast cancer, prostate cancer, and lymphomas. We thus analysed EZH2 expression using real-time reverse transcription-polymerase chain reaction, and correlated its expression status with various clinicopathological parameters in 66 patients with hepatocellular carcinoma (HCC). We found high expression of EZH2 in human liver cancer cell lines. Furthermore, EZH2 gene-expression levels in tumour tissue specimens (0.34+/-0.52) were significantly higher (P<0.0001) than those in the corresponding nontumour tissue specimens (0.07+/-0.09). The incidence of cancer cell invasion into the portal vein was significantly higher (P<0.001) in the high EZH2 expression group (26 of the 33, 79%) than in the low expression group (13 of the 33, 39%). However, there was no significant difference in the disease-free survival rate between the two groups. The findings of this study indicate that EZH2 mRNA expression was upregulated in human HCC and may play an important role in tumour progression, especially by facilitating portal vein invasion.

Abstract
Elongation factor-1 (EF-1) delta is a subunit of EF-1, which is a protein complex that participates in the elongation step of mRNA translation and has recently been considered to correlate with oncogenic transformation. However, there has been no information regarding the clinical significance of EF-1 delta mRNA expression in malignant tumours, including oesophageal carcinoma. Thus, we quantitated the expression of EF-1 delta in malignant and benign oesophageal tissues and associated these levels with clinicopathologic parameters of oesophageal carcinoma. Paired oesophageal tissue samples from cancerous and corresponding noncancerous parts were obtained from 52 patients who underwent curative oesophagectomy. Quantitative analyses of EF-1 delta expression were performed using real-time quantitative reverse transcription–polymerase chain reaction. Elongation factor-1 delta mRNA overexpression in cancerous tissues compared to normal counterparts was observed in 38 of 52 (73%) patients. The mean expression level of EF-1 delta mRNA in cancerous tissues was significantly higher than that in noncancerous tissues (P<0.01). A higher expression of EF-1 delta was significantly correlated with lymph node metastases (P<0.05) and advanced stages (P<0.05). Furthermore, the cause-specific survival of patients with a higher expression of EF-1 delta was significantly poorer than those with a lower expression (5-year cause-specific survival rates; 23 and 54%, respectively, P<0.05). The results of this study indicated that EF-1 delta mRNA expression was significantly higher in cancerous compared to noncancerous oesophageal tissues, and a higher expression of EF-1 delta mRNA was correlated with lymph node metastases, advanced disease stages and poorer prognosis for patients with oesophageal carcinoma.

Abstract
Five men produced 23 ejaculates in 23 assisted reproductive technology cycles for semen analysis. In 11 of the 14 ICSI cycles and in 5 of the 9 IVF cycles, small-head sperm were found in more than 70% of the cells, having a length of < 3.5 micro m and a width of < 2 micro m. In 6 of the 14 ICSI cycles, the embryologist who performed the ICSI was not alerted to e presence of small-head sperm. Subsequent fertilization rate was significantly lower than a) the fertilization rate of the remaining 5 ICSI cycles that acted as a control, in which the embryologist was alerted to the presence of small-head sperm, and b) was lower than the 3 ICSI cycles with normal sperm head (p < .05). The 8 cell embryo and blastocyst rates in the former group were also decreased, although not significantly, compared to the latter groups. Likewise, in the 5 IVF cycles with small-head sperm, the fertilization rate was significantly lower than in the 4 IVF with normal sperm head (p < .05). Embryologists should be alerted when a high percentage of small-head sperm are detected during routine semen analysis because they may be associated with reduced fertilization and embryo outcome.

Abstract
Nerve sheath myxoma (NSM) is a benign peripheral nervous system tumour that rarely occurs in the oral cavity. Among 17 cases of oral NSM described in the literature (average patient age 33 years), only two, including the present case, have been reported in children. The present case occurring in an 8-year-old boy was therefore extremely rare. Histopathologically, the tumour was found as multinodules under the mucosal epithelium, and was composed of spindle- or stellate-shaped cells with a myxoid background that stained with alcian blue and toluidine blue. Immunohistochemically, the tumour cells were strongly positive for S-100 beta protein and neuron-specific enolase. These results suggested that the tumour originated from Schwann cells.

Abstract
OBJECTIVE Beta-catenin activates transcription by TCF/LEF and has been regarded as an oncogene in a wide range of malignant tumors. Among various molecules regulated by beta-catenin/Tcf, cyclin D1 is the most likely candidate for stimulation of the oncogenic pathway. The association between beta-catenin and cyclin D1 was investigated using clinical samples from colorectal cancers. METHODS The expression of beta-catenin and cyclin D1 was investigated by immunohistochemical analyses of samples from 70 patients with colorectal cancers. In 28 of the fresh tumor samples, beta-catenin protein was separated into soluble and insoluble fractions and quantitatively correlated with cyclin D1 protein by Western blot analysis. RESULTS Compared with noncancerous epithelium, beta-catenin and cyclin D1 were overexpressed (+) in 35 (50%) and 30 cases (43%), respectively. Cyclin D1 (+) was observed in 74% (26/35) of beta-catenin (+) cases, but only in 11% (4/35) of the beta-catenin (-) cases. Thus, there was a strong association between the expression of beta-catenin and that of cyclin D1 (p < 0.001). In the Western blot analysis, the amount of cyclin D1 correlated well with beta-catenin expression in the soluble fraction (p = 0.0016), but not with beta-catenin in the insoluble fraction or with E-cadherin expression. Beta-catenin (-)/cyclin D1 (-) cases displayed less tumor invasion than the remaining cases. However, there were no significant differences in lymph node metastasis or other clinicopathological findings. CONCLUSION Our results indicate that beta-catenin overexpression in the cytoplasm may promote malignant transformation by triggering cyclin D1 expression in colorectal cancers.

Abstract
1. The effects of Rho-kinase inhibitor, fasudil, and of a more specific Rho-kinase inhibitor, hydroxyfasudil, on pacing-induced myocardial ischaemia were determined in anaesthetized open-chest dogs. 2. The dogs were subjected to left anterior descending coronary artery (LAD) stenosis producing a sufficient ischaemia as measured by ST-segment depression on electrocardiograms only when the hearts were paced 60 beats min(-1) above the baseline. After a recovery (nonpacing) period, drugs or saline were infused intravenously over 30 min. The animals were again subjected to 5 min of pacing 25 min after the initiation of the treatment. 3. Hydroxyfasudil (0.1 and 0.3 mg kg(-1)) and fasudil (0.3 mg kg(-1)) suppressed the ST-segment depression. Hydroxyfasudil and fasudil also increased the regional blood flow of the LAD perfused endomyocardium region in the canine model of effort angina. 4. To determine the flow profile for hydroxyfasudil in dogs, blood flow in three vascular beds was measured. Hydroxyfasudil (0.3 mg kg(-1) for 30 min) significantly increased coronary blood flow and vertebral blood flow, without significantly changing the femoral blood flow. 5. Hydroxyfasudil had no inotropic or chronotropic effect on the isolated hearts of guinea-pigs. Hydroxyfasudil (2 mg kg(-1) for 20 min) did not affect the PR or QTc interval in anaesthetized dogs. 6. Inhibition of Rho-kinase appears to protect myocardium subjected to pacing-induced ischaemia through the increase in the regional myocardial blood flow. Hydroxyfasudil may be categorized as a novel type of anti-anginal drug, without any inotropic or chronotropic effects.
