Abstract
BACKGROUND A growing body of evidence suggests that non-viral hepatocellular carcinoma (HCC) might benefit less from immunotherapy. MATERIALS AND METHODS We carried out a retrospective analysis of prospectively collected data from consecutive patients with non-viral advanced HCC, treated with atezolizumab plus bevacizumab, lenvatinib, or sorafenib, in 36 centers in 4 countries (Italy, Japan, Republic of Korea, and UK). The primary endpoint was overall survival (OS) with atezolizumab plus bevacizumab versus lenvatinib. Secondary endpoints were progression-free survival (PFS) with atezolizumab plus bevacizumab versus lenvatinib, and OS and PFS with atezolizumab plus bevacizumab versus sorafenib. For the primary and secondary endpoints, we carried out the analysis on the whole population first, and then we divided the cohort into two groups: non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) population and non-NAFLD/NASH population. RESULTS One hundred and ninety patients received atezolizumab plus bevacizumab, 569 patients received lenvatinib, and 210 patients received sorafenib. In the whole population, multivariate analysis showed that treatment with lenvatinib was associated with a longer OS [hazard ratio (HR) 0.65; 95% confidence interval (CI) 0.44-0.95; P = 0.0268] and PFS (HR 0.67; 95% CI 0.51-0.86; P = 0.002) compared to atezolizumab plus bevacizumab. In the NAFLD/NASH population, multivariate analysis confirmed that lenvatinib treatment was associated with a longer OS (HR 0.46; 95% CI 0.26-0.84; P = 0.0110) and PFS (HR 0.55; 95% CI 0.38-0.82; P = 0.031) compared to atezolizumab plus bevacizumab. In the subgroup of non-NAFLD/NASH patients, no difference in OS or PFS was observed between patients treated with lenvatinib and those treated with atezolizumab plus bevacizumab. All these results were confirmed following propensity score matching analysis. By comparing patients receiving atezolizumab plus bevacizumab versus sorafenib, no statistically significant difference in survival was observed. CONCLUSIONS The present analysis conducted on a large number of advanced non-viral HCC patients showed for the first time that treatment with lenvatinib is associated with a significant survival benefit compared to atezolizumab plus bevacizumab, in particular in patients with NAFLD/NASH-related HCC.

Abstract
Abstract
Background
Aortic dissection (AD) is a catastrophic disease that occurs suddenly. The acute mortality is high and those who survived frequently suffer from serious complications such as aneurysm formation and distal ischemia due to progressive destruction of the aortic walls. Currently, no predictor of AD onset is available nor therapeutic intervention to specifically prevent the progressive destruction in AD, because the molecular pathogenesis is largely unknown. Clinical and experimental studies highlighted the importance of inflammation in AD, although the regulatory mechanism of inflammation remains unclear. Recently, we found that cell proliferation precedes the inflammatory response in AD. Because cell proliferation causes cellular senescence that can induce inflammatory response, we hypothesized that cellular senescence participates in AD pathogenesis.
Objective
We investigated if cellular senescence contributes to AD development and progression in mouse AD model.
Methods and results
A mouse AD model was created by continuous infusion of beta-aminopropionitrile and angiotensin II (BAPN+AngII), where AD starts to develop in 3 days and occurs to most of the mice in 14 days accompanied by frequent AD rupture and death. Infusion of BAPN+AngII resulted in the induction of senescence markers Ink4a from day 3 before AD onset and persisted for the 14 days of the observational period.
Cellular senescence, as demonstrated by the expression of senescence-associated beta-galactosidase, was evident in intimal endothelial cells, medial smooth muscle cells, adventitial macrophages and fibroblasts. We examined the role of cellular senescence in AD pathogenesis by oral administration of ABT263 which is known as “senolytics” that eliminates senescent cells. ABT263 treatment reduced the expression of the senescence marker, prevented the death by AD rupture, and ameliorated the severity of AD lesion compared to the vehicle treatment. Transcriptome analysis revealed that ABT treatment suppressed the immune and inflammatory response in AD. Quantitative RT-PCR confirmed that ABT treatment prevented the induction of p21Cip1, interleukin-6, several chemokines and their receptors by 3-day infusion of BAPN+AngII.
Conclusions
These findings demonstrated that senescence of multiple cell types precedes AD development, which is likely to induce the inflammatory response. Elimination of senescent cells effectively prevented AD progression and death. Therefore, cellular senescence represents a potential predictor and a therapeutic target for AD.

The acute mortality is high and those who survived frequently suffer from serious complications such as aneurysm formation and distal ischemia due to progressive destruction of the aortic walls. Currently, no reliable predictor is available for AD development and surgical intervention is the only therapeutic option to prevent the fatal events after AD development, because the pathogenesis of AD is largely unknown.

A mouse AD model was created by continuous infusion of beta-aminopropionitrile and angiotensin II (BAPN+AngII), where AD starts to develop in 3 days and occurs to most of the mice in 14 days accompanied by frequent AD rupture and death. Infusion of BAPN+AngII resulted in the appearance of senescent cells that are positive for senescence-associated beta-galactosidase, and expression of senescence markers Arf and Ink4a in the aortic walls. Appearance of cellular senescence occurred in one day of BAPN+AngII infusion and continued throughout the observational period of 14 days. We examined the role of cellular senescence in AD pathogenesis by oral administration of ABT263 which is known as “senolytics” that eliminates senescent cells. ABT263 treatment reduced the expression of the senescence markers. In the vehicle-treated group, the mortality was 66.7% (12/18), whereas that of ABT263-treated group was 35% (14/20, P<0.05 by log-rank test). The severity of AD, as assessed by the lesion length in vehicle group was33.2±3.1 mm, whereas that in ABT263 group was 24.6±1.8 mm (P<0.05).
Conclusions
These findings demonstrated that cellular senescence precedes AD development, and ABT263 effectively prevented AD progression and death, indicating the involvement of cellular senescence in AD pathogenesis. Therefore, cellular senescence represents a potential predictor and a therapeutic target for AD.

Abstract
Abstract
Background
Aortic dissection (AD) is a fatal disease where the intimomedial layer of the aorta suddenly fail. Although it is widely accepted that hemodynamic stress on the aortic wall triggers its destruction that is further promoted by inflammatory response as exemplified by the infiltration of neutrophils and macrophages, molecular mechanism is unknown for the link of aortic wall stress, inflammation and tissue destruction. In general, mechanical stress to the tissue is converted to the cellular response through the cell adhesion molecules and the activation of focal adhesion kinase (Fak). Although it has been reported that Fak is involved in pathogenesis of aortic aneurysm by promoting migration and activation of macrophages, its role in AD is unknown. We hypothesized that Fak may be involved in AD pathogenesis.
Purpose
We investigated the involvement of Fak in AD pathogenesis, focusing on its role in inflammatory cells.
Methods and results
We created a mouse model of AD by continuous infusion of beta-aminopropionitrile, a collagen crosslink inhibitor, and angiotensin II (BAPN + Ang II). Immunostaining for activated Fak revealed that Fak was not activated in normal aorta, but was activated in the infiltrating inflammatory cells and in interstitial cells of the aortic wall after AD development. We examined the role of Fak by oral administration of PND-1186, a specific Fak inhibitor, in mouse AD model. Vehicle-treated group showed 63.6% mortality, whereas PND-1186-treated group showed 20% mortality (P<0.01, n=20 for each group) in 14 days of the observational period. The aortic arch lesion, the most critical part in AD, was improved from 1.96±0.41 mm in vehicle group to 0.66±0.29 mm in PND group (P<0.05). We next examined the cell type-specific role of Fak in AD by creating macrophage and granulocyte-specific deletion of Fak driven by LysM-Cre and floxed Fak system. Unexpectedly, the genetic deletion of Fak in macrophages and granulocytes had no impact on the mortality nor the severity of AD.
Conclusions
These findings proved that Fak plays a critical role in AD progression and death. Because Fak is dispensable for macrophages and granulocytes, other cell types, possibly aortic wall interstitial cells, may be regulated by Fak in AD pathogenesis. Deciphering the role of Fak would provide the fundamental understanding of AD pathogenesis.

Abstract
Carcinomatous meningitis presents with a variety of neurological symptoms and has a poor prognosis. We encountered a case of carcinomatous meningitis from cervical cancer. A 30-year-old patient was diagnosed with cervical cancer (glassy cell carcinoma), stage IIB. She underwent radical hysterectomy and chemoradiotherapy. Nine months later, the disease recurred with iliac lymph node and right lung metastases. The patient received chemotherapy; however, after seven cycles, the lung lesions increased. The patient responded to supportive care; nevertheless, symptoms including headaches developed and were followed by diplopia. A contrast-enhanced magnetic resonance image of the head confirmed the diagnosis of carcinomatous meningitis. She was transferred to the palliative care unit and died approximately 1 week later. Carcinomatous meningitis has a poor prognosis and is difficult to treat; however, early diagnosis may provide meaningful time to patients. Therefore, attention must be paid to meningeal irritation and neurological symptoms.

Abstract
Background
Aortic dissection (AD) is one of the destructive and fatal aortic diseases, for which molecular pathogenesis is largely unknown. Recent studies have highlighted the importance of inflammatory response in AD. We and others reported that B cells and immunoglobulins participate in pathogenesis of abdominal aortic aneurysm, another form of aortic destructive disease, by promoting inflammatory response. It is not known whether and how B cells participate in AD pathogenesis.
Methods and results
Immunohistochemical staining of human AD tissue revealed that B cells were clustered together with T cells, macrophages and neutrophils at the entry site of AD with medial disruption. B cell cluster was also observed at the site of medial disruption in mouse model of AD that was induced by continuous infusion of beta-aminopropionitrile and angiotensin II (BAPN+AngII). In muMT mouse, which is deficient for B cells and immunoglobulins due to genetic deletion of immunoglobulin heavy chain, BAPN+AngII induced significantly less severe AD compared to that in wild type. Depositions of IgG and fibrinogen, one of the endogenous antigen for natural IgG, were observed after BAPN+AngII infusion before and after AD development in wild type mice. Deposition of fibrinogen was also observed in mMT mice after BAPN+AngII infusion. The rate of aortic rupture and sudden death was approximately 42% in wild type mice, while that in muMT mouse was 12% (P<0.05). Administration of mouse normal polyclonal IgG to muMT mice resulted in dramatic increase in aortic rupture and sudden death, starting at day 7 of BAPN+AngII infusion, and reaching 69% of rupture rate, indicating the critical role of IgG in AD.
Conclusion
These findings demonstrated B cells and IgG are critically involved in the destructive inflammation of AD pathogenesis. Further, the deposition of fibrinogen, one of the targets of natural IgG, precedes the development of AD. Our findings may provide the conceptual foundation of the diagnostic strategy for on-going tissue destruction and for the therapeutic opportunities to intervene the progressive tissue destruction in AD.

Abstract
We herein present a rare case of dedifferentiated liposarcoma originating from the pericardium. A 79-year-old female was referred to our hospital with a pericardial tumor detected by fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT). The tumor, 80×48 mm in size, showed increased uptake of fluorodeoxyglucose on the FDG-PET/CT without any evidence of metastasis. The tumor was resected with the pericardium, and a histopathological examination confirmed the diagnosis of dedifferentiated liposarcoma. Additional chemotherapy, radiation therapy, or a combination of both were offered but refused by the patient. Although the patient was discharged without any complications, the tumor recurred locally 2 months after the surgery, and the patient succumbed 15 months later. The FDG-PET/CT was useful not only in detecting this malignant tumor but also in diagnosing its malignant nature.

Abstract
Abstract
Introduction
Public health care acknowledges socioeconomic factors as one of the multiple facets to promote or protect individual or collective health. Understanding and being more acquainted with the dynamics carried out in riverside communities is fundamental to investing in policies aimed at fighting diseases and illnesses that are particular to those communities.
Objective
Describing socioeconomic characteristics, healthcare infrastructure, and occupational activities of population from riverside communities along Tapajós river, Brazil.
Methodology
A descriptive study with 96 residents of communities of Tapajós river, Brazil. Participants have answered a semi-structure questionnaire and the analyses were descriptive and the variable categories were expressed as frequencies.
Results
There was a predominance of male participants (77.09%), incomplete elementary school (58.51%), involved in agricultural sector (85.10%), with a family income up to 1 minimum wage (68.81%). However, only 21.50% have declared making their living exclusively out of agriculture. Seedlings and seeds are mainly obtained through an exchange system running inside the community. In relation to infrastructure, the water comes from artesian wells (68.88%) and 51.63% claim not treating water whatsoever. All interviewees mentioned the lack of a sewage system and residues are taken to a rudimentary cesspool (76.59%). Waste produced by the community is burned out (93.61%). The main difficulties pointed out by the interviewees were: transportation (44.94%), health (32.14%), communication (21.42%) and government cooperation (15.47%).
Conclusions
The communities in this project show similar structural dynamic based on subsistence family agriculture and poor infrastructure of basic services. The data collected can be the basis for future public policies aiming at the promotion of food production autonomy, economic autonomy, and improvement of health indicators of these communities.
Key messages
Contextualizing the structural dynamic of vulnerable populations is key to plan actions aimed at tackling and dealing with social determinants involved in the health-illness process. Contextualizing the structural dynamic of vulnerable populations is fundamental to guide strategies aimed at intervening in the social and health determinants.

Abstract
Abstract
Background
Aortic dissection (AD) is a fatal disease where the media of the aorta suddenly fail. Currently, Molecular pathogenesis of AD is unknown. Recently, we discovered that the activity of MRTF-A, a mechanosensitive transcriptional regulator, promotes AD development. The activity of MRTF-A is regulated by mechanical stress to cells, which is transduced through focal adhesion and actin dynamics. However, it is currently unknown whether the mechanotransduction mechanism is involved in AD pathogenesis.
Purpose
We investigated the role of focal adhesion kinase (FAK), a signaling molecule that transduces mechanostress from focal adhesion to actin dynamics, in AD pathogenesis.
Methods
We created a mouse model of AD with a continuous infusion of beta-aminopropionitrile (150 mg/kg/day), a collagen crosslink inhibitor, and angiotensin II (1,000 ng/kg/min) (BAPN + AngII) by an osmotic pump. This model caused about 60% death in all mice due to AD rupture within 2 weeks. In this model, we examined the severity and mortality rate of aortic dissection after 2 weeks in mice administered with PND-1186, an orally available FAK inhibitor, and in those treated with vehicle (n=20 for each group). We performed immunochemical staining, immunofluorescence staining and Western blot for activated (phosphorylated) FAK (pFAK) to evaluate the activation status of FAK in the aortic tissue. We also performed transcriptome analysis of the aortic tissue in with and without PND-1186 with BAPN + AngII stimulation before AD development.
Results
Immunochemical staining revealed that FAK was inactive in normal mouse aorta, but was strongly activated in the aortic walls after AD development. Immunofluorescence staining showed that FAK was activated mainly in smooth muscle cells after AD development. Western blot analysis also revealed that FAK was activated in 3 days after BAPN + AngII infusion before AD development, followed by transient reduction at day 7, and re-activation after AD at day 14. Significantly, administration of PND-1186 resulted in a significant reduction in the severity of AD in the aortic arch (1.96±0.41 mm in vehicle group, 0.66±0.29 mm in PND group, P<0.05). In addition, survival rate improved from 36.4% to 80.0% by administration of PND-1186 (P<0.01). In immunofluorescence staining, the PND-1186 treated group showed weaker staining of pFAK. Transcriptome analysis showed that genes for hematopoiesis and immune system were suppressed in PND-1186 treated group.
Conclusions
These findings proved that FAK plays a central role in the pathogenesis of AD probably by transmitting pathological stress to the aortic wall to cause tissue destruction. We propose that FAK is a potential therapeutic target for limiting the fatal destruction of the aortic wall of AD.

Abstract
Abstract
Background
Aortic dissection (AD) is a serious clinical condition with unknown etiology that frequently results in fatal outcome. Recent studies showed essential role of inflammatory response both in promoting AD and aortic aneurysm (AA). However, the difference of the molecular pathogenesis between AD and AA is unclear. Previously, we reported that Syk, a tyrosine kinase that regulates differentiation and activation of inflammatory cells, promotes AA formation in a mouse model.
Objective
In the current study, we investigated the role of Syk in AD.
Methods and results
A mouse AD model was created by continuous infusion of beta-aminopropionitrile (125 mg/kg/day) and angiotensin II (1,000 ng/min/kg) (BAPN+AngII), which caused AD in approximately 80% of mice within 14 days. Immunohistochemical staining for activated (phosphorylated) Syk (pSyk) revealed that Syk was inactive in normal mouse aorta, but was activated in the aortic walls after AD development. Double immunofluorescence staining for pSyk and smooth muscle alpha actin showed that Syk was active not only in the infiltrating inflammatory cells, but also in smooth muscle cells in AD tissue. Western blot analysis revealed that BAPN+AngII treatment caused Syk activation at 3 days before AD development, followed by transient suppression, and reactivation at 14 days after AD development. We examined the significance of Syk activation in AD by treating mice with fostamatinib, a specific Syk inhibitor, before and during BAPN+AngII infusion. Notably, fostamatinib-treated group developed more severe AD compared to the vehicle-treated group. The AD lesion length was 3.80±0.86 mm for vehicle group and 8.87±1.69 mm for fostamatinib group (P<0.05, n=12 for each group). In addition, fostamatinib significantly worsened the mortality of mice due to the rupture of the aorta from 0% to 42% (P<0.05, n=12 for each group). Transcriptome analysis revealed that fostamatinib suppressed both positive and negative regulators of immune response, defense response and inflammatory response.
Conclusions
These findings uncovered the previously unrecognized role of Syk for protecting the aortic tissue in AD pathogenesis, and suggested fundamentally different disease mechanisms of AD and AA.

Abstract
BACKGROUND Work-related psychosocial factors have been associated with metabolic syndrome. However, no systematic reviews or meta-analyses have evaluated this association. METHODS A systematic literature search was conducted, using PubMed, Embase, PsycINFO, PsycARTICLES and the Japan Medical Abstracts Society. Eligible studies included those that examined the previously mentioned association; had a longitudinal or prospective cohort design; were conducted among workers; provided sufficient data for calculating odds ratios, relative risks or hazard ratios with 95% confidence intervals; were original articles in English or Japanese; and were published no later than 2016. Study characteristics, exposure and outcome variables and association measures of studies were extracted by the investigators independently. RESULTS Among 4,664 identified studies, 8 were eligible for review and meta-analysis. The pooled risk of adverse work-related stress on metabolic syndrome onset was significant and positive (RR = 1.47; 95% CI, 1.22-1.78). Sensitivity analyses limiting only the effects of job strain and shift work also indicated a significant positive relationship (RR = 1.75; 95% CI, 1.09-2.79; and RR = 1.59; 95% CI, 1.00-2.54, P = 0.049 respectively). CONCLUSION This study reveals a strong positive association between work-related psychosocial factors and an elevated risk of metabolic syndrome onset. The effects of job strain and shift work on metabolic syndrome appear to be significant.

Abstract
Rose hip is the fruit of the rose plant, which is widely used in food, cosmetics and as a traditional medicine. Therefore, rose hip is considered safe and has a sufficient history of consumption as food. However, few studies have reported on the safety of rose hip extracts in toxicological analyses. Thus, to evaluate the safety of rosehip polyphenol MJ (RHPMJ), an aqueous ethanol extract standardized with the trans-tiliroside content, we performed genotoxicity and 90-day repeated oral dose toxicity studies in compliance with the Organisation for Economic Co-operation and Development-Good Laboratory Practice. RHPMJ did not induce gene mutations in reverse mutation tests of Salmonella typhimurium TA98, TA100, TA1535, TA1537 and Escherichia coli WP2 uvrA strains and did not induce chromosomal aberrations in cultured Chinese hamster lung (CHL/IU) cells. Moreover, micronucleus tests using rat bone marrow showed RHPMJ had no micronucleus-inducing potential. Finally, 90-day repeated oral dose toxicity studies (100–1000 mg/kg) in male and female rats showed no treatment-related toxicity in rats. These data indicate that the RHPMJ had no genotoxicity and a no-observed-adverse-effect level greater than 1000 mg/kg in rats.

Abstract
OBJECTIVE To investigate the diagnostic utility of endometrial (EM) cell block (CB) cytology for the detection of intrauterine malignancy in postmenopausal women. METHODS We reviewed the medical records of 104 postmenopausal women between January 2012 and November 2014. We reviewed symptoms upon admission, body mass index, parity, transvaginal ultrasonographic findings, and histopathological results based on CB and conventional cytology. RESULTS The mean age was 62.6 (range 48-95) years. The mean menopausal age was 50.8 years and the mean duration of menopause was 12.0 years. The sensitivity of CB and conventional cytology was 82.3% (29/35) and 85.7% (30/35) and the specificity was 98.6% (68/69) and 94.2% (65/69), respectively. The sensitivity and specificity of CB cytology combined with conventional cytology were 82.3% (29/35) and 94.2% (65/69), respectively. The predictive values for EM hyperplasia and type-II carcinoma were 100 and 85.7%, respectively. CONCLUSION CB cytology provides specimens for examination in a single outpatient session. Additionally, immunohistochemical staining can provide useful information for histological diagnosis. A combination of CB and conventional cytology can improve the diagnostic accuracy of EM lesions and may be a valid method for screening in postmenopausal women.

Abstract
This study investigated whether an intestinal epithelial culture method can be applied to mouse and human esophageal cultures. The esophagi harvested from 1-day-old mice and adult humans were maintained in collagen gels. A commercially available culture medium for human embryonic stem cells was used for the human esophageal culture. We discovered that the intestinal epithelial culture method can be successfully applied to both mouse and human esophageal cultures. The long-term cultured esophageal organoids were rod-like luminal structures lined with myofibroblasts. We discovered that regeneration of the esophageal mucosal surface can be almost completely achieved in vitro, and the advantage of this method is that organoid cultures may be generated using host-derived fibroblasts as a niche. This method is a promising tool for mouse and human research in intestinal biology, carcinogenesis, and regenerative medicine.

Abstract
A tumor thrombus of the portal vein is refractory to therapy and constitutes a serious prognostic factor in hepatocellular carcinoma. For the purpose of treating portal vein tumor thrombus by restoring the blood flow and preventing recurrent ingrowth of tumor, we devised a metallic stent partially covered with a Dacron mesh sheet, and a coaxial percutaneous delivery system. One half of the wall of a Gianturco Z-stent was covered with a sheet of 0.25-mm-thick Dacron mesh, fixed to the stent wall with nylon threads. The covered stent was implanted in a patient with severe main portal vein stenosis due to tumor thrombus protruding from the left portal vein branch. Immediately after stent placement the tumor stenosis was effectively dilated, the portal blood flow restored, and the portal hypertension relieved. CT and angiography after 8 months still showed complete portal vein patency. Intrahepatic tumor dissemination or other complications were not observed. Intraportal placement of a covered metallic stent appears to be an efficacious therapy of major portal tumor thrombi.

Abstract
STUDY DESIGN This is a single-center retrospective study. OBJECTIVES The objective of this study was to study the clinical symptoms and electrophysiological features of C6-7 myelopathy. SETTING This study was conducted at the Department of Orthopedic surgery, Yamaguchi University Graduate school of medicine, Japan. METHODS A total of 20 patients with cervical compressive myelopathy were determined by spinal cord-evoked potentials or a single level of obvious magnetic resonance imaging (MRI)-documented cervical spinal cord compression. Neurological examinations included manual muscle testing and investigation of deep tendon reflex, including Hoffmann sign, and of sensory disturbance areas. Motor-evoked potentials (MEPs), compound muscle action potentials (CMAPs) and F-wave were recorded from bilateral abductor digit minim and abductor halluces muscles. Central motor conduction time was calculated as follows: MEPs latency-(CMAPs latency+F latency-1)/2 (ms). RESULTS Eighteen patients (90%) had negative Hoffmann sign. Eight patients (40%) had no sensory disturbance in the upper limbs and 8 patients (40%) had no muscle weakness in the upper limbs. We determined that patients had cervical myelopathy when their central motor conduction time measured in abductor digit minim was longer than 6.76 ms (+2 s.d.). Using this definition, the sensitivity for myelopathy was 42.8%. CONCLUSION Patients with C6-7 myelopathy may lack clinical symptoms in their hands and central motor conduction time measured in abductor digit minim tended to be less prolonged, and it only showed symptoms in their lower limbs as gait disturbance. Surgeons should bear in mind the possibility of disorders of caudal C6-7 when they encounter patients with no or few symptoms in their hands and with leg weakness or numbness.

Abstract
Significant associations of HLA-DP alleles with chronic hepatitis B (CHB) infection are evident in Asian and Arabian populations, including Japanese, Han Chinese, Korean, and Saudi Arabian populations. Here, significant associations between CHB infection and five DPB1 alleles (two susceptibility alleles, DPB1(*) 05:01 and (*) 09:01, and three protective alleles, DPB1(*) 02:01, (*) 04:01, and (*) 04:02) were confirmed in a population comprising of 2582 Japanese individuals. Furthermore, odds ratios for CHB were higher for those with both DPB1 susceptibility alleles than for those with only one susceptibility allele; therefore, effects of susceptibility alleles were additive for risk of CHB infection. Similarly, protective alleles showed an additive effect on protection from CHB infection. Moreover, heterozygotes of any protective allele showed stronger association with CHB than did homozygotes, suggesting that heterozygotes may bind a greater variety of hepatitis B-derived peptides, and thus present these peptides more efficiently to T-cell receptors than homozygotes. Notably, compound heterozygote of the protective allele (any one of DPB1*02:01, *04:01, and *04:02) and the susceptible allele DPB1*05:01 was significantly associated with protection against CHB infection, which indicates that one protective HLA-DPB1 molecule can provide dominant protection. Identification of the HLA-DPB1 genotypes associated with susceptibility to and protection from CHB infection is essential for future analysis of the mechanisms responsible for immune recognition of hepatitis B virus antigens by HLA-DPB1 molecules.

Abstract
BACKGROUND X-linked lymphoproliferative syndrome type 2 is a rare hereditary immunodeficiency caused by mutations in the XIAP gene. This immunodeficiency frequently results in hemophagocytic lymphohistiocytosis, although hypogammaglobulinemia and dysgammaglobulinemia are also common. OBJECTIVE We identified 17 patients from 12 Japanese families with mutations in XIAP. The Glu349del mutation was observed in 3 patients, each from a different family. Interestingly, these patients exhibited dysgammaglobulinemia but not hemophagocytic lymphohistiocytosis. We conducted an immunological study of patients carrying Glu349del and other mutations to elucidate the pathogenic mechanisms of dysgammaglobulinemia in patients with mutations in the XIAP gene. PATIENTS AND METHODS We performed an immunological study of 2 patients carrying the Glu349del mutation and 8 patients with other mutations. RESULTS Flow cytometry showed that the percentage of memory B cells in patients with a mutation in XIAP was lower than that observed in the healthy controls. The patients with the Glu349del mutation had a lower percentage of memory B cells than those with other mutations. Ig production was reduced in patients with the Glu349del mutation. Increased susceptibility to apoptosis was observed in the patients with other mutations. Susceptibility to apoptosis was normal in patients with Glu349del. Microarray analysis indicated that expression of Ig-related genes was reduced in patients with the Glu349del mutation and that the pattern was different from that observed in the healthy controls or patients with other mutations in XIAP. CONCLUSIONS Patients carrying the Glu349del mutation in the XIAP gene may have a clinically and immunologically distinct phenotype from patients with other XIAP mutations. The Glu349del mutation may be associated with dysgammaglobulinemia.

Abstract
Background: Pancreatic cancer has a poor prognosis because of its high refractoriness to chemotherapy and tumour recurrence, and these properties have been attributed to cancer stem cells (CSCs). MicroRNA (miRNA) regulates various molecular mechanisms of cancer progression associated with CSCs. This study aimed to identify the candidate miRNA and to characterise the clinical significance. Methods: We established gemcitabine-resistant Panc1 cells, and induced CSC-like properties through sphere formation. Candidate miRNAs were selected through microarray analysis. The overexpression and knockdown experiments were performed by evaluating the in vitro cell growth and in vivo tumourigenicity. The expression was studied in 24 pancreatic cancer samples after laser captured microdissection and by immunohistochemical staining. Results: The in vitro drug sensitivity of pancreatic cancer cells was altered according to the miR-1246 expression via CCNG2. In vivo, we found that miR-1246 could increase tumour-initiating potential and induced drug resistance. A high expression level of miR-1246 was correlated with a worse prognosis and CCNG2 expression was significantly lower in those patients. Conclusions: miR-1246 expression was associated with chemoresistance and CSC-like properties via CCNG2, and could predict worse prognosis in pancreatic cancer patients.

Abstract
Vascular neoplasms of the pancreas are extremely rare and usually manifest as symptomatic, cystic lesions. This study presents a case that includes the clinicopathologic information used to discriminate pancreatic hemangioma from other types of cystic lesion of the pancreas. A 40-year-old female visited hospital with a chief complaint of abdominal pain. The serum CEA and CA19-9 levels of the patient were within the normal limits. An abdominal computed tomography scan and magnetic resonance imaging showed a 100-mm mass lesion in the body and tail of the pancreas, and the tumor extended toward the retroperitoneum and surrounded the splenic vein. The lesion was subsequently resected. Macroscopically, it was a multiloculated cyst with intracystic hemorrhage. Microscopically, the lesion was composed of numerous, heterogeneous cysts lined by a flattened single layer of cells without significant atypia. Notably, numerous neoplastic vessels extended into the interlobular septa of the pancreas and surrounded the main pancreatic duct. Immunohistochemical analysis showed that the lining cells expressed CD31 and CD34. The lesion was diagnosed as adult pancreatic hemangioma. Surgical treatment may be required when a direct contact between the lesion and the pancreatic tissue is demonstrated using imaging.

Abstract
A rare case of squamous cell carcinoma (SCC) with apocrine features was investigated; the focus was on the histological characteristics of the cancer cells in a 68-year-old female exhibiting an ulcerated lesion of the right breast. Diagnostic imaging methods identified a lobulated solid tumor and indicated multiple enlarged lymph nodes in the left axilla, which confirmed the diagnosis of advanced breast cancer; thus, a mastectomy was performed. Macroscopic investigations identified the tumor as a white, solid lesion measuring 66 × 68 × 47 mm, which exhibited necrosis. Histologically, the tumor was predominantly solid and exhibited nest patterns, in addition to intracellular keratinization. Immunohistochemical staining identified the tumor cells as positive for cytokeratin 5/6, 34βE12 and P63. The lesion was considered to be an SCC demonstrating negative expression for the human epidermal growth factor receptor 2, estrogen receptor and progesterone receptor; therefore, the tumor was a triple-negative breast cancer. Conversely, approximately one-third of the tumor cells indicated abundant eosinophilic cytoplasm and gross cystic disease fluid, which was demonstrated via protein-15 staining; this indicated the presence of apocrine features. In addition, the androgen receptor was expressed in the tumor cells, thus the lesion was diagnosed as an SCC of the breast, exhibiting apocrine features.

Abstract
AIM: To investigate the clinicopathological features of intraductal neoplasm of the intrahepatic bile duct (INihB).
METHODS: Clinicopathological features of 24 cases of INihB, which were previously diagnosed as biliary papillomatosis or intraductal growth of intrahepatic biliary neoplasm, were reviewed. Mucin immunohistochemistry was performed for mucin (MUC)1, MUC2, MUC5AC and MUC6. Ki-67, P53 and β-catenin immunoreactivity were also examined. We categorized each tumor as adenoma (low grade), borderline (intermediate grade), and malignant (carcinoma in situ, high grade including tumors with microinvasion).
RESULTS: Among 24 cases of INihB, we identified 24 tumors. Twenty of 24 tumors (83%) were composed of a papillary structure; the same feature observed in intraductal papillary neoplasm of the bile duct (IPNB). In contrast, the remaining four tumors (17%) showed both tubular and papillary structures. In three of the four tumors (75%), macroscopic mucin secretion was limited but microscopic intracellular mucin was evident. Histologically, 16 tumors (67%) were malignant, three (12%) were borderline, and five (21%) were adenoma. Microinvasion was found in four cases (17%). Immunohistochemical analysis revealed that MUC1 was not expressed in the borderline/adenoma group but was expressed only in malignant lesions (P = 0.0095). Ki-67 labeling index (LI) was significantly higher in the malignant group than in the borderline/adenoma group (22.2 ± 15.5 vs 7.5 ± 6.3, P < 0.01). In the 16 malignant cases, expression of MUC5AC showed borderline significant association with high Ki-67 LI (P = 0.0622). Nuclear expression of β-catenin was observed in two (8%) of the 24 tumors, and these two tumors also showed MUC1 expression. P53 was negative in all tumors.
CONCLUSION: Some cases of INihB have a tubular structure, and are subcategorized as IPNB with tubular structure. MUC1 expression in INihB correlates positively with degree of malignancy.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) ranks as the third leading cause of cancer deaths worldwide. While sorafenib, a multikinase inhibitor targeting the Raf/extracellular signal-regulated protein kinase (ERK) pathway, has been shown recently to provide a survival advantage to patients with advanced HCC, a predictive biomarker has not been developed. We studied whether c-Jun N-terminal kinase (JNK), which promotes liver carcinogenesis in mice, affects therapeutic response to sorafenib in HCC patients. METHODS We collected pathological specimens from 39 patients with advanced HCC before starting sorafenib treatment, and measured JNK activity in HCCs. RESULTS In patients treated with sorafenib, the expression of phospho-c-Jun in HCC, as a read out of JNK activity, was significantly higher (P<0.001) in the non-responder group than in the responder group. c-Jun N-terminal kinase activation in HCC was associated with a decreased time to progression and a poor overall survival (P=0.0028 and P=0.0008, respectively). CONCLUSION In addition, JNK activity was significantly correlated with CD133 expression level. Correspondingly, high expression level of CD133 was linked to a poor response to sorafenib. Furthermore, D-JNKi, a specific JNK inhibitor, reduced the growth of xenografted CD133(+) cells in athymic mice. In conclusion, JNK activation was positively correlated with CD133 expression level and inversely correlated with the therapeutic response to sorafenib, suggesting that JNK activity may be considered as a new predictive biomarker for response to sorafenib treatment.

Abstract
Recently, single nucleotide polymorphisms (SNPs) have been used to identify genes or genomic regions responsible for economic traits, including genetic diseases in domestic animals, and to examine genetic diversity of populations. In this study, we genotyped 70 chicken autosomal SNPs using DigiTag2 assay to understand the genetic structure of the Japanese native chicken breeds Satsumadori and Ingie, and the relationship of these breeds with other established breeds, Rhode Island Red (RIR), commercial broiler and layer. Five breeds, each consisting of approximately 20 chickens, were subjected to the assay, revealing the following: Average expected heterozygosities of broiler, Satsumadori, RIR, layer and Ingie were 0.265, 0.254, 0.244, 0.179 and 0.176, respectively. Phylogenetic analysis using the concatenated 70 autosomal SNP genotypes distinguished all chickens and formed clusters of chickens belonging to the respective breeds. In addition, the 2-D scatter plot of the first two principal components was consistent with the phylogenic tree. Taken together with the pairwise F(st) distances, broiler and RIR were closely positioned near each other, while Ingie was positioned far from the other breeds. Structure analysis revealed that the probable number of genetic clusters (K) was six and four with maximum likelihood and ΔK values, respectively. The clustering with maximum likelihood revealed that, in addition to the clustering of the other five breeds, the Satsumadori was subdivided into two genetic clusters. The clustering with ΔK value indicated that the broiler and Rhode Island Red were assigned to the same genetic cluster.

Abstract
Selective laser melting (SLM) is a useful technique for preparing three-dimensional porous bodies with complicated internal structures directly from titanium (Ti) powders without any intermediate processing steps, with the products being expected to be useful as a bone substitute. In this study the necessary SLM processing conditions to obtain a dense product, such as the laser power, scanning speed, and hatching pattern, were investigated using a Ti powder of less than 45 μm particle size. The results show that a fully dense plate thinner than 1.8 mm was obtained when the laser power to scanning speed ratio was greater than 0.5 and the hatch spacing was less than the laser diameter, with a 30 μm thick powder layer. Porous Ti metals with structures analogous to human cancellous bone were fabricated and the compressive strength measured. The compressive strength was in the range 35-120 MPa when the porosity was in the range 75-55%. Porous Ti metals fabricated by SLM were heat-treated at 1300 °C for 1h in an argon gas atmosphere to smooth the surface. Such prepared specimens were subjected to NaOH, HCl, and heat treatment to provide bioactivity. Field emission scanning electron micrographs showed that fine networks of titanium oxide were formed over the whole surface of the porous body. These treated porous bodies formed bone-like apatite on their surfaces in a simulated body fluid within 3 days. In vivo studies showed that new bone penetrated into the pores and directly bonded to the walls within 12 weeks after implantation into the femur of Japanese white rabbits. The percentage bone affinity indices of the chemical- and heat-treated porous bodies were significantly higher than that of untreated implants.

Abstract
Chromosome 5q31 spans the T helper (Th) 2-related cytokine gene cluster, which is potentially important in Th1/Th2 immune responses. The chromosome 5q23.2-31.3 has been recently identified as a region with suggestive evidence of linkage to tuberculosis in the Asian population. With the aim of fine-mapping a putative tuberculosis susceptibility locus, we investigated a family-based association test between the dense single nucleotide polymorphism (SNP) markers within chromosome 5q31 and tuberculosis in 205 Thai trio families. Of these, 75 SNPs located within candidate genes covering SLC22A4, SLC22A5, IRF1, IL5, RAD50, IL13, IL4, KIF3A and SEPT8 were genotyped using the DigiTag2 assay. Association analysis revealed the most significant association with tuberculosis in haplotypes comprising SNPs rs274559, rs274554 and rs274553 of SLC22A5 gene (P(Global)=2.02 x 10(-6)), which remained significant after multiple testing correction. In addition, two haplotypes within the SLC22A4 and KIF3A region were associated with tuberculosis. Haplotypes of SLC22A5 were significantly associated with the expression levels of RAD50 and IL13. The results show that the variants carried by the haplotypes of SLC22A4, SLC22A5 and KIF3A region potentially contribute to tuberculosis susceptibility among the Thai population.

Abstract
The progression of periodontitis may be affected by ALDH2 genotypes with respect to the oxidation of acetaldehyde to acetate, which leads to the accumulation of acetaldehyde in plasma and potential toxic effects. We examined the prospective association of ALDH2 genotypes in terms of alcohol sensitivity between alcohol consumption and periodontal disease progression. In 2003, 224 of 256 (87.5%) individuals examined at baseline (1999) completed probing pocket depth measurements for the evaluation of periodontitis progression. Missing data on self-reported questionnaires and blood samples were excluded; therefore, 183 samples were analyzed. Individuals who consumed > or = 33.0 g/day of alcohol exhibited high periodontal disease progression risk (OR = 3.54). ALDH2 *1/*2 individuals who consumed > or = 33 g/day of alcohol displayed a significant odds ratio (OR = 4.28) of periodontitis progression risk, in contrast to ALDH2 *1/*1 individuals. These results suggested that alcohol consumption as well as alcohol sensitivity may be a risk factor for periodontitis progression.
