Abstract
We have developed a focusing system for extreme ultraviolet light produced by high-order harmonic generation. An ellipsoidal mirror with a precise surface shape was fabricated and installed into the focusing system. A rigid mirror manipulator and a beam profiler were employed to perform precise and stable mirror alignment. As a demonstration of the focusing performance, high-order harmonics in the wavelength range of 13.5-19.5 nm were successfully focused into a 2.4 × 2.3 μm(2) spot.

Abstract
BACKGROUND Bronchial asthma is characterised by airway inflammation and remodelling with a decline of lung function. Fibrocytes are bone marrow-derived mesenchymal progenitor cells that play important roles in the pathogenesis of airway remodelling. Several clinical parameters are currently being used in routine clinical practice to assess outcome of therapy in asthma including frequency of rescue with short-acting β2-agonist and the asthma control test. In this study, we hypothesised that asthma control test is associated with circulating levels of fibrocytes in bronchial asthma. METHODS There were 20 patients with asthma and seven healthy controls. The number of CD45(+)Collagen I(+) circulating fibrocytes was assessed in the peripheral blood by flow cytometry. RESULTS The number of circulating fibrocytes was significantly increased in asthma patients with moderate and severe disease compared to controls, and it was inversely correlated with % forced expiratory volume in one second and % forced vital capacity (%FVC). The frequency of inhalation of short-acting β2 agonist and the asthma control test score was significantly and inversely correlated with the number of circulating fibrocytes. CONCLUSION The results of this study showed that the number of circulating fibrocytes is inversely correlated with clinical asthma control parameters, further supporting the relevance of measuring circulating fibrocytes as a marker of clinical control in bronchial asthma.

Abstract
Vasohibin‐1 (VASH1) is a negative feedback regulator of angiogenesis, the first to be discovered, and was identified in vascular endothelial growth factor (VEGF)‐stimulated vascular endothelial cells. Vasohibin‐1 inhibits abnormal vascularization induced by various angiogenic factors including fibroblast growth factor and platelet‐derived growth factor (PDGF), in addition to VEGF. By focusing on this characteristic of VASH1, we investigated the antitumor effects of VASH1 expression on ovarian cancer cells that produce different angiogenic factors. By using a high VEGF‐producing ovarian cancer cell line, SHIN‐3, and a high PDGF‐producing ovarian cancer cell line, KOC‐2S, the cells were transfected with either a VEGF antagonist, soluble VEGF receptor‐1 (sVEGFR‐1, or sFlt‐1), or VASH1 genes to establish their respective cellular expression. The characteristics of these transfectants were compared with controls. We previously reported that the expression of sFlt‐1 inhibited tumor vascularization and growth of high VEGF‐producing ovarian cancer cells, reduced peritoneal dissemination and ascites development, and prolonged the survival time of the host. However, in the current study, the expression of sFlt‐1 had no such effect on the high PDGF‐producing ovarian cancer cells used here, whereas VASH1 expression inhibited tumor vascularization and growth, not only in high VEGF‐producing cells, but also in high PDGF‐producing cells, reduced their peritoneal dissemination and ascites, and prolonged the survival time of the host. These results suggest that VASH1 is an effective treatment for ovarian cancer cells that produce different angiogenic factors.

Abstract
Vasohibin-1 (VASH1) is expressed in vascular endothelial cells stimulated by several angiogenic growth factors and displays autocrine activity to regulate angiogenesis via a negative feedback mechanism. In this study, we investigated the effect of VASH1 on ovarian cancer progression using VASH1-expressing ovarian cancer cells in vitro and in vivo. The growth ability of ovarian cancer cells engineered to express the VASH1 gene remained unchanged in vitro. However, we showed that VASH1 secretion by tumor cells inhibited the growth of human umbilical vein endothelial cells. Further, animal experiments showed that VASH1 expression inhibited tumor angiogenesis and growth. In a murine model of peritoneal dissemination of ovarian cancer cells, VASH1 inhibited peritoneal dissemination and ascites, resulting in significantly prolonged survival in mice. This indicates that VASH1 exerts an antitumor effect on ovarian cancer by inhibiting angiogenesis in the tumor environment. These findings suggest that a novel therapy based on VASH1 could be a useful therapeutic strategy for ovarian cancer.

Abstract
Uterine clear cell adenocarcinoma (UCCA) is rare and resistant to treatment. We report a UCCA patient who responded to radiotherapy on each relapse. The first relapse was detected in the vaginal wall after the first course of postoperative adjuvant chemotherapy. Radiotherapy was conducted. Recurrent tumors were detected in the left lung after 5 months and in the right lung after 8 months. Partial resection of the lungs was performed. After 5 months, relapse was detected in the left pulmonary apex. Stereotactic radiotherapy was conducted. After 7 months, relapse was detected in the left pulmonary apex outside the irradiation field, and stereotactic radiotherapy was performed. During the subsequent 36-month follow-up, there has been no relapse. Although UCCA is resistant to treatment, radiotherapy is effective in some cases, as demonstrated in this patient. Even when relapse is repeated, radiotherapy may be considered as a treatment option if the recurrent focus is localized.

Abstract
Primary gestational choriocarcinoma is commonly present in the uterus in cases of atypical genital bleeding. Symptoms similar to those of an ectopic pregnancy develop when an extra-uterine lesion is present in the abdominal cavity, and lesions have been detected in the ovaries and fallopian tubes in a number of cases. In the present study, we describe a patient with choriocarcinoma that metastasized to the uterine serosa and caused symptoms similar to those of an ectopic pregnancy. The patient was a 30-year-old female who presented to our hospital with atypical genital bleeding and a positive pregnancy test 3 months after missed abortion at 10 weeks of gestation. Transvaginal ultrasonography revealed the absence of a gestational sac in or outside the uterus, and intra-abdominal bleeding was noted. An ectopic pregnancy was suspected based on these findings, and emergency laparotomy was performed. A hemorrhagic mass was present on the uterine serosa, and was subsequently resected. Trophoblastic disease was suspected following histopathological examination, for which intra-uterine curettage was performed and choriocarcinoma was diagnosed. Lung metastasis was detected on computed tomography, and a high serum human chorionic gonadotropin (hCG) level persisted following surgery. The lesion disappeared following five cycles of methotrexate+ etoposide+actinomycin D therapy, which was performed as postoperative chemotherapy, and the patient's serum hCG level decreased to below the detection limit. In this case of choriocarcinoma, the primary lesion was present in the uterus and had metastasized to the uterine serosa, which is a very rare metastatic site. This uterine serosal metastatic lesion bled and caused symptoms similar to those of an ectopic pregnancy. Certain patients who undergo surgery for a suspected peritoneal pregnancy may have gestational choriocarcinoma, similar to this case.

Abstract
BACKGROUND In Japan, the cervical cancer screening rate is extremely low. Towards improving the cervical cancer screening rate, encouraging eligible people to make an informed choice, which is a decision-making process that relies on beliefs informed by adequate information about the possible benefits and risks of screening, has attracted increased attention in the public health domain. However, there is concern that providing information on possible risks of screening might prevent deter from participating. METHODS In total, 1,912 women aged 20-39 years who had not participated in screening in the fiscal year were selected from a Japanese urban community setting. Participants were randomly divided into 3 groups. Group A received a printed reminder with information about the possible benefits of screening, group B received a printed reminder with information about possible benefits and risks, and group C received a printed reminder with simple information only (control group). RESULTS Out of 1,912 participants, 169 (8.8%) participated in cervical cancer screening. In the intervention groups, 137 (10.9%) participated in cervical cancer screening, compared to only 32 (4.9%) of the control group (p < 0.001). In addition, logistic regression analysis revealed that there was no significant difference in screening rate between group A and group B (p = 0.372). CONCLUSIONS Providing information on the possible risks of screening may not prevent people from taking part in cervical cancer screening among a Japanese non-adherent population.

Abstract
BACKGROUND Biliary complications remain the leading cause of postoperative complications after living-donor liver transplantation (LDLT) in patients undergoing duct-to-duct choledochocholedochostomy. The aim of this study was to analyze the causes of these complications. METHODS One hundred eight patients who underwent LDLT with duct-to-duct biliary reconstruction at Mie University Hospital were enrolled in this study. The mean follow-up time was 58.4 months (range, 3-132). The most recent 18 donors underwent indocyanine green (ICG) fluorescence cholangiography for donor hepatectomy. The development of biliary complications was retrospectively analyzed. Biliary complications were defined as needing endoscopic or radiologic treatment. RESULTS Biliary leakages and strictures occurred in 6 (5.6%) and 15 (13.9%) of the recipients, respectively, and 3 donors (2.7%) experienced biliary leakage. However, since the introduction of ICG fluorescence cholangiography, we have not encountered any biliary complications in either donors or recipients. Biliary leakage was an independent risk factor for the development of biliary stricture (P = .013). Twelve (80%) of the 15 recipients with biliary stricture had successful nonoperative endoscopic or radiologic management, and 3 patients underwent surgical repair with hepaticojejunosotomy. CONCLUSIONS Biliary leakage was an independent factor for biliary stricture. ICG fluorescence cholangiography might be helpful to reduce biliary complications after LDLT in both donors and recipients.

Abstract
BACKGROUND Alcohol consumption is a major cause of liver injury but the mechanisms are not completely understood. Protein S (PS) is an anticoagulant glycoprotein with multiple functions. The role of PS in liver injury is unknown. OBJECTIVES This study investigated the role of PS in acute alcoholic hepatitis. METHODS A mouse overexpressing human PS (hPS-TG) was generated in which acute hepatitis was induced by intraperitoneal injection of ethanol. RESULTS The levels of serum liver enzymes and liver tissue inflammatory cytokines and the degree of hepatic steatosis were significantly increased in hPS-TG mice treated with ethanol compared with ethanol-treated wild type (WT) mice. Cell expansion, activation and inhibition of apoptosis were significantly augmented in natural killer T (NKT) cells from hPS-TG mice compared with WT mice. Liver mononuclear cells from hPS-TG mice express higher levels of inflammatory cytokines than those from WT mice after stimulation with a specific stimulant of NKT cells in vitro. In a co-culture system of hepatocytes and NKT cells, the effects of PS on ethanol-mediated cell injury were suppressed by a CD1d neutralizing antibody. Alcoholic liver injury was significantly improved in mice pre-treated with PS siRNA and anti-protein S antibody compared with control mice. Patients with alcoholic hepatitis showed significantly increased plasma PS levels and enhanced liver expression of PS and CD1d compared with controls. CONCLUSIONS The results of this study suggest that PS exacerbates acute alcoholic hepatitis by inhibiting apoptosis of activated NKT cells.

Abstract
Vasohibin-2 (VASH2) is a homolog of vasohibin-1 and exhibits pro-angiogenic activity. We recently reported that VASH2 is expressed in certain ovarian cancers and promotes tumor growth through angiogenesis. To further demonstrate the effectiveness of molecular targeting of VASH2 for anticancer treatment, we applied in vivo delivery of siRNA targeting VASH2 (siVASH2) using atelocollagen to a xenograft model of ovarian cancer. We inoculated mice s.c. with DISS and SKOV-3, two representative human ovarian serous adenocarcinoma cell lines. When tumors were measurable, we initiated treatment with control or siVASH2 mixed with atelocollagen, which enveloped the whole tumor. Treatment with siVASH2 significantly inhibited s.c. tumor growth by abrogating tumor angiogenesis. We confirmed that expression of VASH2 mRNA in the tumor was downregulated by siVASH2 treatment. In addition, the siVASH2-treated tumor contained more blood vessels covered with pericytes, indicating that knockdown of VASH2 contributes to the normalization of tumor blood vessels. Based on these results, VASH2 may be a promising molecular target for ovarian cancer treatment.
