Abstract
INTRODUCTION Sustainability in healthcare is a rapidly developing area of research with recent formal recognition from institutions around the world. We completed an update of a systematic review published in 2020. The aims of this review were to determine the reported carbon footprints of surgical operations in hospitals worldwide, identify variations in reported carbon footprints and highlight carbon hotspots associated with surgery. METHODS A systematic review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. The MEDLINE®, Embase® and Cochrane Library databases were searched, and eligibility criteria applied. The study characteristics, scope of product inventory and results were extracted and synthesised. A quality assessment of each study was completed to inform the reliability of the research. RESULTS 1,308 articles were identified and 7 met the inclusion criteria for the review. The carbon footprint ranged from 28.49kg to 505.1kg carbon dioxide equivalents (CO2e). Medical devices and consumables were the greatest contributor to emissions, with material production and manufacture representing the majority of this carbon hotspot. There were significant methodological limitations and a lack of consistency in carbon footprint calculations between studies. CONCLUSIONS This systematic review identifies medical devices and consumables as the largest carbon hotspot where healthcare providers should target their sustainability initiatives. Nevertheless, the number of studies was limited and the quality of the evidence was weak. We recommend that researchers in healthcare sustainability develop international standards for conducting and reporting such studies. This would allow for comparison of individual studies and facilitate meta-analysis of cumulative evidence. A reliable evidence base is a prerequisite for identifying optimal interventions to ensure societal benefits.

Abstract
ABSTRACT Warthin tumor is the second most common benign tumor of salivary glands. Here we present an interesting case of squamous cell carcinoma arising from the Warthin tumor in the cervical lymph node. The patient had another Warthin tumor in the parotid gland as well. Both the malignant transformation of Warthin tumor and the heterotopic occurrence of Warthin tumor in the cervical lymph node are rare. This exceptionally rare case demonstrates that the 2 rare clinical entities can occur simultaneously and affect clinical decisions.

Abstract
Chemokines with their network play an important role in cancer growth, metastasis, and host-tumor interactions. Of many chemokines, C-C motif chemokine ligand 24 (CCL24) has been shown to contribute to tumorigenesis as well as inflammatory diseases like asthma, allergies, and eosinophilic esophagitis. CCL24 is expressed in some tumor cells such as colon cancer, hepatocellular carcinoma, and cutaneous T cell lymphoma. CCL24 can be used as a potential biomarker in several cancers including colon cancer, non-small cell cancer, and nasopharyngeal carcinoma as the plasma level of CCL24 is increased. The various functions of CCL24 contribute to the biology of cancer by M2 macrophage polarization, angiogenesis, invasion and migration, and recruitment of eosinophils.

Abstract
BACKGROUND Interstitial fibrosis and tubular atrophy (IFTA) is a well-recognized risk factor for poor renal outcome in patients with diabetic kidney disease (DKD). However, a noninvasive biomarker for IFTA is currently lacking. The purpose of this study was to identify urinary markers of IFTA and to determine their clinical relevance as predictors of renal prognosis. METHODS Seventy patients with biopsy-proven isolated DKD were enrolled in this study. We measured multiple urinary inflammatory cytokines and chemokines by multiplex enzyme-linked immunosorbent assay in these patients and evaluated their association with various pathologic features and renal outcomes. RESULTS Patients enrolled in this study exhibited advanced DKD at the time of renal biopsy, characterized by moderate to severe renal dysfunction [mean estimated glomerular filtration rate (eGFR) 36.1 mL/min/1.73 m2] and heavy proteinuria (mean urinary protein:creatinine ratio 7.8 g/g creatinine). Clinicopathologic analysis revealed that higher IFTA scores were associated with worse baseline eGFR (P < 0.001) and poor renal outcome (P = 0.002), whereas glomerular injury scores were not. Among measured urinary inflammatory markers, C-X-C motif ligand 16 (CXCL16) and endostatin showed strong correlations with IFTA scores (P = 0.001 and P < 0.001, respectively), and patients with higher levels of urinary CXCL16 and/or endostatin experienced significantly rapid renal progression compared with other patients (P < 0.001). Finally, increased urinary CXCL16 and endostatin were independent risk factors for poor renal outcome after multivariate adjustments (95% confidence interval 1.070-3.455, P = 0.029). CONCLUSIONS Urinary CXCL16 and endostatin could reflect the degree of IFTA and serve as biomarkers of renal outcome in patients with advanced DKD.

Abstract
Substance P (SP), an injury-inducible messenger that mobilizes bone marrow stem cells and modulates the immune response, has been suggested as a novel target for therapeutic agents. We evaluated the role of SP as an immune cell modulator during the progression of renal ischemic/reperfusion injury (IRI). Unilateral IRI induced the transient expression of endogenous SP and the infiltration of CCR7+ M1 macrophages in injured kidneys. However, SP altered the intrarenal macrophage polarization from CCR7+ M1 macrophages to CD206+ M2 macrophages in injured kidneys. SP also modulated bone marrow-derived neutrophils and mesenchymal stromal cells after IRI. SP treatment for 4 weeks starting one week after unilateral IRI significantly preserved kidney size and length and normal tubular structures and alleviated necrotic tubules, inflammation, apoptosis, and tubulointerstitial fibrosis. The beneficial effects of SP were accompanied by attenuation of intrarenal recruitment of CD4, CD8, and CD20 cells and abnormal angiogenesis. The immunomodulatory effect of SP suggested that SP could be a promising therapeutic target for preventing the progression of acute kidney injury to chronic kidney disease.

Abstract
We describe the case of a 41-year-old woman with primary Sjögren's syndrome (SS) who presented multiple recurrences of breast amyloidosis. Each recurrence of breast amyloidosis showed different sonographic features, potentially mimicking malignancy. We briefly discuss the possible cause of this variability in imaging features based on the radiologic-histologic correlation.

Abstract
BACKGROUND C-MYC appears to initiate and maintain tumorigenesis through modulation of immune regulatory molecules such as PD-L1. The aim of our research was to evaluate the clinical implication of C-MYC expression in gastric adenocarcinoma in relation to the expression of the immune regulatory molecules PD-L1 and FOXP3. METHODS Tissue samples were acquired from 182 cases of gastric adenocarcinoma that were surgically resected at Kyung Hee University Hospital at Gangdong from 2006 to 2012. Immunohistochemical staining for C-MYC, PD-L1, CD8 and FOXP3 was done. RESULTS C-MYC overexpression showed a significant correlation with smaller tumor size, lower T category, lower N category, lower recurrence rate, and less lymphatic invasion. And C-MYC overexpression was negatively correlated with PD-L1 expression. The tumoral FOXP3 was positively correlated with C-MYC overexpression and Tregs count. PD-L1 expression was positively correlated with Tregs, CD8 + T cells, and tumor infiltrating lymphocytes (TIL). Tregs count was positively correlated with CD8 + T cells and TIL. CD8 + T cells was positively correlated with TIL. CONCLUSION We discovered that the immune regulatory effect of C-MYC and PD-L1, and the tumor suppressor function of tumoral FOXP3 had a significant influence on the tumor microenvironment (Tregs, CD8 + T cells, and tumor infiltrating lymphocytes) in a complex manner. The C-MYC overexpression is a good prognostic factor in gastric adenocarcinoma.

Abstract
During aging, the kidney undergoes functional and physiological changes that are closely affiliated with chronic kidney disease (CKD). There is increasing evidence supporting the role of lipid or lipid-derived mediators in the pathogenesis of CKD and other aging-related diseases. To understand the role of lipids in various metabolic processes during kidney aging, we conducted matrix-assisted laser desorption/ionization-imaging mass spectrometry (MALDI-IMS) analysis in kidneys harvested from young (2 months old, n = 3) and old mice (24 months old, n = 3). MALDI-IMS analysis showed an increase in ceramide level and a decrease in sphingomyelin (SM) and phosphatidylcholine (PC) levels in kidneys of old mice. The increased expression of cPLA2 and SMPD1 protein in aged kidney was confirmed by immunohistochemistry and Western blot analysis. Our MALDI-IMS data showed the altered distribution of lipids in aged kidney as indicative of aging-related functional changes of the kidney. Combined analysis of MALDI-IMS and IHC confirmed lipidomic changes and expression levels of responsible enzymes as well as morphological changes.

Abstract
Endocan is a water-soluble proteoglycan exclusively secreted by vascular endothelium. Endocan levels may be elevated in kidney transplant recipients experiencing antibody-mediated rejection (ABMR), which is characterized by vascular inflammation in transplanted kidney. We evaluated the clinical relevance of endocan as markers of microvascular inflammation in patients who underwent kidney transplantation. Plasma and urinary endocan levels were measured in 203 kidney transplant recipients and were compared across different etiologies of allograft dysfunction and various pathologic scores. Both plasma and urinary endocan levels were significantly higher in patients with acute ABMR than those in patients with normal pathology, acute tubular necrosis (ATN), acute pyelonephritis, BK virus associated nephropathy (BKVN), and T-cell mediated rejection (TCMR). Patients with chronic active ABMR also exhibited significantly higher plasma and urinary endocan levels than patients with long-term graft survival. Scores of glomerulitis and peritubular capillaritis, which are typical features of microvascular inflammation, were significantly elevated in patients with higher plasma and/or urinary endocan levels. Furthermore, plasma and urinary endocan levels could effectively discriminate ABMR from ATN, BKVN, and TCMR. Finally, patients exhibiting high urinary and plasma endocan levels in acute ABMR group showed significantly worse renal survival. Altogether, plasma and urinary endocan levels may serve as potential markers of microvascular inflammation in kidney transplant recipients.

Abstract
BACKGROUND/AIM Identifying the role of the sympathetic nervous system (SNS) in tumor progression is among the most important challenges in cancer research. This study aimed to investigate the role of the SNS and β-adrenoreceptor in gastric cancer progression. MATERIALS AND METHODS The density of SNS was quantified by immunohistochemical staining for tyrosine hydroxylase in 115 surgically-resected gastric cancer specimens. Immunostaining for β1- and β2-adrenoreceptor was also performed to examine the β-adrenoreceptor expression status in gastric cancer. Then the association of protein expression status with histological grade, pathological tumor stage (pT), and pathological node stage of gastric cancer was investigated. RESULTS The SNS density of pT4 tumors was significantly lower than that of pT1-3 tumors. The SNS density was positively correlated with β1-adrenoreceptor expression status. In addition, lower β1-adrenoreceptor expression was significantly associated with increased lymph node metastasis. Reduced β2-adrenoreceptor staining proportion was significantly associated with worse histological grade. Furthermore, the proportion of β2-adrenoreceptor staining was significantly lower in tumors with diffuse-type histology, than those with intestinal-type histology. CONCLUSION A lower SNS density and β-adrenoreceptor expression was associated with an aggressive oncogenic behavior including worse histological grade, advanced pT, and increased lymph node metastasis. SNS and β-adrenergic pathway are involved in the negative regulation of gastric cancer progression.

AIMS The aim of this study was to evaluate the outcomes of a salvage procedure using a 95° angled blade plate for failed osteosynthesis of atypical subtrochanteric femoral fractures associated with the long-term use of bisphosphonates. These were compared with those for failed osteosynthesis of subtrochanteric fractures not associated with bisphosphonate treatment. PATIENTS AND METHODS Between October 2008 and July 2016, 14 patients with failed osteosynthesis of an atypical subtrochanteric femoral fracture were treated with a blade plate (atypical group). Their mean age was 67.8 years (60 to 74); all were female. During the same period, 21 patients with failed osteosynthesis of a typical subtrochanteric fracture underwent restabilization using a blade plate (typical group). Outcome variables included the time of union, postoperative complications, Harris Hip Score, and Sanders functional rating scale. RESULTS In the atypical group, union was achieved in 12 patients (85.7%) at a mean of 8.4 months (4 to 12). The mean follow-up was 31.2 months (12 to 92) The plate broke in one patient requiring further stabilization with a longer plate and strut-allograft. Another patient with failure of fixation and varus angulation at the fracture site declined further surgery. In the typical group, union was achieved in 18 patients (85.7%) at a mean of 7.9 months (4 to 12). There was no difference in the mean Harris Hip Score between the two groups (83.1 points vs 86.8 points; p = 0.522) at the time of final follow-up. Sanders functional rating scores were good or excellent in 78.6% of the atypical group and in 81.0% of the typical group. CONCLUSION The 95° angled blade plate was shown to be an effective fixation modality for nonunion of atypical subtrochanteric fractures with a high rate of union and functional improvement, comparable to those after fractures not associated with bisphosphonate treatment.

Abstract
BACKGROUND/AIMS Non-alcoholic fatty liver disease is associated with insulin resistance. Compound K (CK) is the final metabolite of panaxadiol ginsenosides that have been shown to exert antidiabetic effects. However, the molecular mechanism of the antidiabetic effects in the liver have not been elucidated; further, whether CK has beneficial effects in hepatosteatosis remains unclear. Therefore, we evaluated the effect of CK on hepatosteatosis as well as its mechanism in high-fat diet (HFD)-fed type 2 diabetic Otsuka Long-Evans Tokushima Fatty (OLETF) rats. METHODS Twenty-four-week-old male OLETF rats were assigned to four groups: control (saline), CK 10 mg/kg, CK 25 mg/kg, or metformin 300 mg/kg (positive control); all treatments were administered orally for 12 weeks. RESULTS Fasting glucose levels of the CK25 group were significantly lower than those of the control group during the 12 weeks. The results of the oral glucose tolerance test showed that both the glucose concentration after glucose loading and the fasting insulin levels of the CK25 group were significantly lower than those of the control. Hepatosteatosis was significantly improved by CK25. CK25 and metformin significantly increased the phosphorylation of hepatic adenosine monophosphate-activated protein kinase (AMPK). CK25 significantly inhibited the expression of sterol regulatory element-binding protein-1c and fatty acid synthase, while upregulating that of peroxisome proliferator-activated receptor-α and carnitine palmitoyltransferase-1. CONCLUSIONS CK improved glucose intolerance and hepatosteatosis in HFD-fed OLETF rats through AMPK activation, which has dual mode of action that involves decreasing the synthesis of fatty acids and increasing fatty acid oxidation.

Abstract
Cholescintigraphy has traditionally been used as a tool to select patients with biliary pain for elective cholecystectomy. However, atypical biliary pain presents a clinical challenge and there is no literature evaluating the factors of the gallbladder (GB) wall related to abnormal ejection fraction of cholescintigraphy in such patients. Therefore, we aimed to evaluate characteristics of the GB wall in patients with abnormal gallbladder ejection fraction (GBEF) on cholescintigraphy and atypical biliary pain. Patients who underwent cholescintigraphy for atypical biliary pain and subsequent cholecystectomy were initially recruited for this study. Medical records and pathologic findings of these patients were retrospectively reviewed. Parameters that were significant on univariate analysis, including factors of GB wall and cholescintigraphy, were subsequently tested by multivariate analysis to identify independent predictors for abnormal GBEF. Abnormal or low GBEF was defined as GBEF <35%. A total of 41 adult patients were divided into a low GBEF (n = 15) and a high GBEF group (n = 26) based on the cutoff value of 35%. In univariate analysis mean muscle thickness, muscle to total layer ratio, and muscle to fibrosis layer ratio were significantly higher in the low GBEF group than in the high GBEF group. In multivariate analysis, the muscle to fibrosis layer ratio was found to be an independent risk factor for abnormal GBEF (odds ratio = 3.514, 95% confidence interval = 1.058-11.673, P = .04). The fibrosis to total layer ratio was negatively correlated with GBEF in the low GBEF group (r = -0.657, P < .01). Muscle to fibrosis layer ratio was significantly associated with decreased GBEF. The fibrosis thickness ratio also seems to play an important role in patients with decreased GBEF.

Abstract
The function and contribution of tumoral FOXP3 in gastric cancer development remain poorly understood. Thus, we studied the expression of tumoral FOXP3 and its relationship with the well-known tumor suppressor proteins P21 and P53 in gastric adenocarcinoma. The tissue microarray was constructed from 182 cases of gastric adenocarcinoma. The immunohistochemistry was performed on 4-μm tissue sections from each tissue microarray block. We found that positive tumoral FOXP3 expression was significantly correlated with a lower T category, a lower N category, a lower recurrence rate, and less lymphatic invasion. Furthermore, the survival analysis revealed that the tumoral FOXP3-positive group had significantly increased overall survival and disease-free survival rates compared with the tumoral FOXP3-negative group. Additionally, P21 expression showed a significant positive correlation with tumoral FOXP3 expression in gastric adenocarcinoma cells. Taken together, these findings demonstrate that tumoral FOXP3 expression is associated with favorable clinicopathological variables and good prognosis in gastric adenocarcinoma through increased expression of the tumor suppression protein P21.

Abstract
Aims This study aimed to compare the clinical outcomes of rotator cuff repair in patients with rheumatoid arthritis with those of patients who have no known history of the disease. We hypothesised that the functional outcomes are comparable between patients and without rheumatoid arthritis and may be affected by the level of disease activity, as assessed from C-reactive protein (CRP) level and history of systemic steroid intake. Patients and methods We conducted a retrospective review of the institutional surgical database from May 1995 to April 2012. Twenty-nine patients with rheumatoid arthritis who had rotator cuff repair were enrolled as the study group. Age, sex, and tear size matched patients with no disease who were selected as the control group. The mean duration of follow-up was 46 months (range 24-92 months). Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons (ASES) questionnaire, Constant score and visual analogue scale (VAS). All data were recorded preoperatively and at regular postoperative follow-up visits. CRP was measured preoperatively as the disease activity marker for rheumatoid arthritis. Medication history was thoroughly reviewed in the study group. Results In patients with rheumatoid arthritis, all shoulder functional scores improved after surgery (ASES 56.1-78.1, Constant 50.8-70.5 and VAS 5.2-2.5; P < 0.001). The functional outcome of surgery in patients with rheumatoid arthritis was comparable to that of the control group (difference with control: ASES 78.1 vs. 85.5, P = 0.093; Constant 70.5 vs. 75.9, P = 0.366; VAS 2.5 vs. 1.8, P = 0.108). Patients with rheumatoid arthritis who had an elevated CRP level (> 1 mg/dl) showed inferior clinical outcomes than those with normal CRP levels. Patients with a history of systemic steroid intake showed inferior functional outcomes than those who had not taken steroids. Conclusions Surgical intervention for rotator cuff tear in patients with rheumatoid arthritis improved the shoulder functional outcome comparable to that in matched patients without rheumatoid arthritis. Elevated preoperative CRP level and history of systemic steroid intake portend inferior functional outcome in patients with rheumatoid arthritis.

Abstract
We hypothesized that cancer stem cells (CSCs) are responsible for the poor outcome and aggressive clinicopathological factors. We surveyed the expression of selected CSC markers that are specifically expressed in thyroid papillary carcinoma (PTC). A total of 80 patients with PTC from 2011 to 2012 were enrolled. We selected CD24, CD44, CD133, and dehydrogenase 1 (ALDH1), as they have been suggested to be candidate CSC markers. Expression of these markers was investigated by immunohistochemical (IHC) staining. IHC staining for CD24, CD44, CD133 and ALDH1 was evaluated according to staining intensity and proportion. The intensity and proportion scores were multiplied together for a total score, which was either 0-2 (negative) or 3-7 (positive). IHC for CD133 in PTC was positive in 49 (61.3%) patients, and CD24 was positive in 28 (35.0%). Seventy-eight (97.5%) patients were CD44 positive and 79 (98.8%) were ALDH1 positive. When we assessed the relationship between CSC markers and clinicopathological factors in PTC, CD24 expression was inversely correlated with multifocality (p=0.045; odds ratio [OR], 0.370; 95% confidence interval [CI], 0.138-0.991) and CD44 expression was significantly correlated with a BRAF mutation (p=0.001; OR, 7.091; 95% CI, 4.101-12.262). However, CD133 and ALDH1 were not associated with any of the clinicopathological parameters. CD24 expression was inversely correlated with multifocality, and CD44 expression was significantly correlated with a BRAF mutation. Therefore, CD24 and CD44 are related to clinicopathological aggressive features and important for determining surgical extent in patients with PTC.

Abstract
INTRODUCTION Von Willebrand factor propeptide (VWF:Ag II) is proposed to be a more sensitive marker of acute endothelial activation than von Willebrand factor antigen (VWF:Ag). Simultaneous data on VWF:Ag and VWF:Ag II profiles are very limited following TIA and ischaemic stroke. METHODS In this prospective, observational, case-control study, plasma VWF:Ag and VWF:Ag II levels were quantified in 164 patients≤4weeks of TIA or ischaemic stroke (baseline), and then ≥14days (14d) and ≥90days (90d) later, and compared with those from 27 healthy controls. TIA and stroke subtyping was performed according to the TOAST classification. The relationship between VWF:Ag and VWF:Ag II levels and platelet activation status was assessed. RESULTS 'Unadjusted' VWF:Ag and VWF:Ag II levels were higher in patients at baseline, 14d and 90d than in controls (p≤0.03). VWF:Ag levels remained higher in patients than controls at baseline (p≤0.03), but not at 14d or 90d after controlling for differences in age or hypertension, and were higher in patients at baseline and 90d after controlling for smoking status (p≤0.04). 'Adjusted' VWF:Ag II levels were not higher in patients than controls after controlling for age, hypertension or smoking (p≥0.1). Patients with symptomatic carotid stenosis (N=46) had higher VWF:Ag and VWF:Ag II levels than controls at all time-points (p≤0.002). There was no significant correlation between platelet activation status and VWF:Ag or VWF:Ag II levels. CONCLUSIONS VWF:Ag and VWF:Ag II levels are increased in an overall TIA and ischaemic stroke population, especially in patients with recently symptomatic carotid stenosis. VWF:Ag II was not superior to VWF:Ag at detecting acute endothelial activation in this cohort and might reflect timing of blood sampling in our study.

Abstract
We sequenced and characterized the complete mitogenome (KX964606) of the Amur hedgehog Erinaceus amurensis to provide more data for comparative mitogenomics of the genus Erinaceus (Erinaceidae). The mitogenome of E. amurensis is a circular molecule 16,941 bp long, consisting of a control region and a conserved set of 37 genes containing 13 protein-coding genes, 22 tRNA genes, and two rRNA genes (12S rRNA and 16S rRNA). The mitogenome of E. amurensis is AT-biased, with a nucleotide composition of 33.9% A, 21.1% C, 32.6% T, and 12.4% G. The mitogenomes of E. amurensis and the closely related hedgehog species E. europaeus, excluding the control region (66.7%), share over 90% sequence similarity. According to the inter-generic relationship based on six mitogenomes described from five genera of Erinaceidae, the subfamilies Erinaceinae and Galericinae are strongly supported as monophyletic groups, with each genus well placed within its own subfamily. Within the subfamily Erinaceinae, E. amurensis is a sister species to E. europaeus, and the relationship between Hemiechinus and Erinaceus is strongly supported. Within the subfamily Galericinae, the clade of Hylomys + Neotetracus was sister to that of Echinosorex, with clades supported by high values. Our findings will help to understand the codon usage pattern and molecular evolution of E. amurensis, and provide insight into inter-generic relationships within the family Erinaceidae. In future studies, the inclusion of mitogenomes from other genera would greatly enhance our understanding of higher phylogeny within the Erinaceidae.

Abstract
PURPOSE p53, widely known as a tumor-suppressing gene, has recently been reported to regulate glucose metabolism in human cancers through the synthesis of cytochrome c oxidase 2 (SCO2), cytochrome c oxidase complex (COX), and TP53-induced glycolysis and apoptosis regulator (TIGAR). In this study, we investigated the interrelations of the aforementioned proteins, particularly in human gastric cancer, with cancer progression, other clinicopathological parameters, and patient outcomes. MATERIALS AND METHODS One hundred and ten cases of primary gastric cancer occurring from June 2006 to June 2009 were investigated and classified into two groups according to the intensity of immunohistochemical staining for p53, SCO2, COX, and TIGAR. The clinicopathological data were organized and analyzed based on electronic medical records. RESULTS In accordance with previous reports, the expression of p53 showed an inverse correlation with the expression of TIGAR (p=0.032) in gastric cancer cells. However, the expression of SCO2 and COX were not shown to be associated with the regulatory role of p53, unlike TIGAR expression. Nevertheless, a significantly high recurrence rate was found in a patient group with high COX expression (p=0.012). CONCLUSIONS This study demonstrated that a high p53 expression could be associated with the promotion of glycolysis in gastric cancer via the modulation of TIGAR expression. In addition, a high COX expression appeared to be interrelated with poor prognosis of gastric cancer. However, further studies regarding the underlying molecular interactions are required to provide more evidence to propose a novel mechanism that explains our findings in gastric cancer.

Abstract
Background Crystalloid podocytopathy with focal segmental glomerulosclerosis in plasma cell myeloma (PCM) is rare. Case Presentation We present a case of crystalline deposition in the bone marrow (BM) and various renal cells with only proteinuria as a symptom. As workup for proteinuria, a renal biopsy sample was obtained. EM showed multiple crystalline depositions in renal tubular cells and podocytes. Focal segmental glomerulosclerosis with crystalloid podocytopathy was diagnosed. Because monoclonal gammopathy was detected in the serum and urine, a BM study was also performed. Plasma cells with needle-shaped inclusion bodies were observed. The crystalline deposits in the plasma cells and podocytes were positive for Masson’s trichrome and kappa light-chain staining. These findings indicated that the crystalline deposits originated from paraprotein. The case showed a rare process of focal segmental glomerulosclerosis via crystalline deposition in podocytes in plasma cell myeloma. Conclusions Crystalloid podocytopathy is a likely cause of renal damage such as FSGS in PCM, although it is an uncommon mechanism for myeloma kidney.

Abstract
Nucleolar protein PICT-1/GLTSCR2 (GLTSCR2) has both tumor suppressive and oncogenic activities, depending on the types of cancer tissue and its expression level. The role of GLTSCR2 in renal cell carcinoma (RCC) has not yet been addressed. The aims of this study were to evaluate GLTSCR2 expression in RCC tissue and to determine pathological significance of GLTSCR2 in terms of tumor grade. RCC and adjacent normal tissue from 84 different patients was retrieved from nephrectomy specimens. The expression level of GLTSCR2 in RCC tissues was determined via immunohistochemical staining and invasion was determined using transwell chambers with Matrigel-coated membranes. The expression of GLTSCR2 was suppressed in about 80% of the carcinoma specimens compared to noncancerous renal tissue and inversely correlated with Fuhrman nuclear grade (r=-0.40, p<0.05). Knockdown of GLTSCR2 expression increased the invasiveness of SNU267 RCC cells. The expression of GLTSCR2 was suppressed in RCCs and its downregulation accentuated the malignant phenotype.

Abstract
Background: A decrease in the number of tissue eosinophils is known to reflect the malignancy potential of neoplastic lesions and even prognosis. Increased levels of the chemokines CCL11 and CCL24 in serum and tissue are also known to have diagnostic value as serum tumor markers or prognostic factors. The aim of this study was to evaluate the correlation between the degree of tissue eosinophilia and the expression of these chemokines in the glandular and stromal cells of colorectal neoplastic lesions ranging from benign to malignant tumors. Methods: We counted the number of infiltrating eosinophils in neoplastic lesion tissue and we evaluated the expression of CCL11 and CCL24 in glandular cells and stromal cells by immunohistochemical staining. Results: The results showed that the number of eosinophils decreased significantly and the expression of CCL11 and CCL24 in glandular cells decreased with tumor progression, whereas the stromal expression of CCL11 and CCL24 appeared to increase. Conclusions: The discrepancy in CCL11 and CCL24 expression between glandular cells and stromal cells might shed light on how colorectal cancer evades the immune system, which would enable further development of immunotherapies that target these chemokines. Further research on eosinophil biology and the expression pattern of chemokines in tumor cells is needed.

Abstract
FOXP3 is a transcription factor and well-known hallmark of immune suppressive T regulatory cells (Tregs). Recent studies indicate that, in addition to its association with Treg function in the immune system, FOXP3 plays an important role in tumor development. And important tumor suppressor relay between the FOXP3 and Hippo pathways was found in human cancer. Thus, we investigated tumoral FOXP3, infiltrated Tregs count, Lats2, and YAP expression in gastric adenocarcinoma, and the relationships between expression of these three proteins and p53, Ki67, and other clinicopathological variables. We used 118 gastric adenocarcinoma tissues via immunohistochemical analysis, using a tissue microarray, in relation to survival and other clinicopathological factors. We report the several novel observations about the relationship between tumoral FOXP3 and Hippo pathway components in gastric adenocarcinoma. Positive tumoral FOXP3 expression was significantly related with smaller tumor size, tubular tumor type, lower histological grade, lower T stage, lower recurrence rate, less lymphatic invasion, and less neural invasion. Furthermore, patients with positive tumoral FOXP3 experienced significantly better disease-free and overall survival compared to patients with negative tumoral FOXP3. These findings show that tumoral FOXP3 expression is associated with favorable clinicopathological variables in gastric adenocarcinoma. And we report the novel observation of a relationship between tumoral FOXP3 and Hippo pathway components in gastric adenocarcinoma. Tumoral FOXP3 expression, infiltrated Tregs count, and Lats2 expression were all positively correlated with YAP expression. These findings suggest that the Hippo pathway in gastric adenocarcinoma might be influenced by both tumoral FOXP3 and infiltrated Tregs. In conclusion, the loss of FOXP3 expression in cancer cells is thought to contribute to tumorigenesis and progression of gastric adenocarcinoma. The expression of FOXP3 in gastric adenocarcinoma is related with Lats2 and YAP expression of the Hippo pathway.

Abstract
Proinflammatory T helper 1 (Th1) and T helper 17 (Th17) cell subsets have been reported to have an immunopathogenic role in metabolic disease. We previously demonstrated that CD4(+) T cells are increased in kidneys in type 2 diabetic patients. However, the role of Th1 and Th17 cells in the development and progression of diabetic nephropathy is unclear. In this study, we examined the hypothesis that mycophenolate mofetil (MMF) attenuates diabetic kidney injury by the suppression of renal T-cell proliferation and related cytokines. Four groups of male C57/BL6 mice (8-weeks-old) were studied: (1) untreated controls, (2) MMF-treated controls (30 mg/kg of body weight per day), (3) streptozotocin (STZ)-induced diabetes, and (4) MMF-treated STZ-induced diabetes. The interferon gamma (IFN-γ) and interleukin 17 (IL-17) from renal CD4(+) T cells were analyzed in kidney mononuclear cells by flow cytometry. We found proliferating CD4(+) T cells were significantly increased in the kidney compared with the spleen. There were increases in IFN-γ(+) CD4(+) and IL-17A(+) CD4(+) T cells from the initiation of albuminuria in the kidneys of diabetic mice. We found MMF suppresses only the intrarenal IL-17A(+) CD4(+) T cells from early diabetic nephropathy and improves albuminuria, tubulointerstitial fibrosis independent of glycemic control. Our study results suggest that Th17 may play an independent role in the progression of diabetic nephropathy and modulation of IL-17 has potential as an immunologic therapeutic target.

Abstract
There have been several studies on gallbladder carcinogenesis, and mutations of the KRAS, TP53, and CDKN2A genes have been reported in gallbladder carcinoma. The DBC1 gene (deleted in breast cancer 1) was initially cloned from region 8p21, which was homozygously deleted in breast cancer. DBC1 has been implicated in cancer cell proliferation and death. The functional role of DBC1 in normal cells and the role of DBC1 loss in cancer are not entirely clear. And DBC1 expression and its clinical implications in gallbladder carcinoma have yet to be thoroughly elucidated. Therefore, we evaluated DBC1 expression in 104 gallbladder carcinoma tissues in relation to survival and other prognostic factors via immunohistochemical analysis. DBC1 expression was divided into two categories: high DBC1 expression was observed in 32/104 cases (30.8%) and low expression in 72/104 cases (69.2%). High DBC1 expression correlated significantly with favorable clinicopathologic variables. Furthermore, in survival analysis, the high-DBC1 expression group showed a better survival rate compared to the low-DBC1 expression group. In conclusion, high DBC1 expression is associated with several favorable clinicopathologic factors in gallbladder carcinoma. These findings suggest that loss of DBC1 expression plays a role in tumorigenesis and tumor progression in gallbladder carcinoma.

Abstract
DNA hypomethylation was the initial epigenetic abnormality recognized in human malignancy. In the present study, the GoldenGate high-throughput genotyping assay was adapted to determine the methylation state of 1,505 specific CpG sites in 807 cancer-related genes. The methylation results revealed that CC chemokine receptor 5 (CCR5) was hypomethylated (mean β-value difference, -0.21) in clear cell renal cell carcinoma (CCRCC) tissue. Tissue samples from 61 CCRCC cases were used for immunohistochemical staining, and patients with low CCR5 expression (n=44) were compared with those with high CCR5 expression (n=17). Tumor (T) stage was significantly lower in the low expression group compared with the high expression group (P=0.047). The Fuhrman grade of patients in the low expression group was significantly lower than that of patients in the high expression group (P=0.044). Whilst the node (N) and metastasis (M) stages of the CCR5 low expression group appeared to be lower compared with those of the CCR5 high expression group; this difference was not statistically significant (N stage, P=0.632; M stage, P=0.896). Additionally, patients in the low expression group had lower risks of postoperative tumor recurrence (P=0.110) and mortality from CCRCC (P=0.159) compared with those in the high expression group, however, this was also without statistical significance. The results indicate that CCR5 hypomethylation is associated with cancer tissue to a greater extent than normal tissue. Although the biological function of CCR5 in CCRCC remains to be established, low CCR5 expression is associated with low T stage and low Fuhrman grade in these patients.

Abstract
Background There is growing research evidence that subclinical autistic traits are elevated in relatives of individuals with autism spectrum disorder (ASD), continuously distributed in the general population and likely to share common etiology with ASD. A number of measures have been developed to assess autistic traits quantitatively in unselected samples. So far, the Quantitative-Checklist for Autism in Toddlers (Q-CHAT) is one of very few measures developed for use with toddlers as young as 18 months, but little is known about its measurement properties and factor structure. Methods The present study examined internal consistency, factor structure, test-retest stability, and convergent validity of the Q-CHAT in a sample of toddlers in Singapore whose caregivers completed the Q-CHAT at 18 (n = 368) and 24 months (n = 396). Results Three factors were derived accounting for 38.1 % of the variance: social/communication traits, non-social/behavioral traits, and a speech/language factor. Internal consistency was suboptimal for the total and speech/language scores, but acceptable for the social/communication and non-social/behavioral factor scores. Scores were generally stable between 18 and 24 months. Convergent validity was found with the Pervasive Developmental Disorders subscale of the Child Behavior Checklist (CBCL) completed by caregivers when their children were 24 months. Q-CHAT total scores in this sample were higher than those reported in other unselected samples from the UK. Conclusions The Q-CHAT was found to have a three-factor structure, acceptable internal consistency for its two main factor scores (social/communication and non-social/behavioral), normally distributed scores in an unselected sample, and similar structure and measurement properties as those reported in other published studies. Findings are discussed in relation to existing literature and future directions for the validation of the Q-CHAT.

Abstract
BACKGROUND AND AIM The anti-inflammatory effects of liquiritigenin, a major flavonoid isolated from Glycyrrhizae uralensis, have been reported in many inflammation models. However, its protective effects have not been reported in a colitis model. This study investigated the anti-inflammatory effect and mechanism of liquiritigenin for trinitrobenzene sulfonic acid (TNBS)-induced colitis in mice. METHODS Male mice imprinting control regions (ICR) were randomly divided into five groups: normal, TNBS-induced colitis, colitis treated with liquiritigenin at low dose (10 mg/kg) and high dose (20 mg/kg), or mesalazine (10 mg/kg). TNBS colitis induction was performed except for in the normal group, and they were treated with liquiritigenin or mesalazine except control group. The treatment effect was measured after three days treatment, by body weight, colon length, macroscopic score, histological score, levels of cytokines (tumor necrosis factor-α, interleukin [IL]-1β, IL-6, and IL-10) in colon tissue as well as the nuclear factor kappa-light-chain-enhancer pathway of activated B cells (NF-κB) activation. RESULTS Mice treated with high-dose liquiritigenin showed significant body weight gain, inhibition of colon shortening, protective effect on histological damages, and myeloperoxidase activity of colon tissue compared with the control group. Furthermore, mice treated with high-dose liquiritigenin experienced significantly suppressed tumor necrosis factor-α, IL-1β, and IL-6 as well as enhanced IL-10 expression (all P < 0.05). High-dose liquiritigenin treatment group showed significant decreases in TNBS-induced phosphorylation of IKKβ, p65, and IκB-α. CONCLUSION Liquiritigenin may ameliorate TNBS-induced colitis in mice by suppressing expression of pro-inflammatory cytokines through NF-κB pathway.

Abstract
Beclin-1 induces autophagy, which is known to be involved in many physiopathological processes such as cell development, aging, stress response, immune response and cancer. Several studies showed that Beclin-1 expression is associated with several prognostic factors of gastric carcinomas. Recently, the connection between autophagy and the hedgehog (HH) signaling pathway has been studied. Here, we investigated the relationship between the autophagy and hedgehog (HH) signaling pathways in gastric adenocarcinoma. We evaluated Beclin-1 and Gli2 expression in 108 gastric adenocarcinoma tissues via immunohistochemical analysis, using a tissue microarray, in relation to survival and other prognostic factors. Our results show that increased Beclin-1 expression is correlated with favorable clinicopathological variables including histologic grade, tumor size, primary tumor (T) stage, lymph node metastasis, lymphatic invasion, neural invasion, and tumor recurrence. Furthermore, increased Gli-2 expression was correlated with several favorable clinicopathological variables including primary tumor (T) stage, lymphatic invasion, and tumor recurrence. Increased Beclin-1 expression was significantly correlated with increased Gli2. Univariate analyses for disease-free survival and overall survival revealed that the higher Beclin-1 and Gli2 expression group had a more favorable prognosis compared with the lower Beclin-1 and Gli2 expression group. Our results suggest that progressively increased Beclin-1 and Gli2 expression contributes to the inhibition of tumor growth and metastasis in gastric adenocarcinoma and Beclin-1 acts as a tumor suppressor by regulating the HH signaling pathway through Gli2 expression in gastric adenocarcinoma.

Abstract
DNA hypermethylation plays a major role in the regulation of gene expression in differentiation, development and diseases. The DNA mismatch repair system, which includes Mut-S-Homologon-2 (MSH2) protein, is essential to maintain the stability of the genome during repeated duplication. This study aimed to investigate tumoral MSH2 immunohistochemical expression in clear cell renal cell carcinoma (RCC), and the associations between tumoral MSH2 immunohistochemical expression and clinicopathological parameters. Previously, we reported a high-throughput method for analyzing the methylation status of 807 preselected genes; Illumina’s GoldenGate Methylation Cancer Panel I microarray. The MSH2 gene was identified to be hypermethylated in cancer tissue compared with normal tissue. From January 2000 to December 2012, 129 clear cell RCC cases (median age, 61 years) were included in the immunohistochemical analysis of the present study. Patients were divided according to MSH2 expression status (MSH2-negative, n=53; MSH2-positive, n=76). T stage was significantly higher in the MSH2-negative group than in the MSH2 positive-group (P=0.021). There was no significant difference in terms of N stage, M stage and Fuhrman’s nuclear grade between the MSH2-negative and MSH2-positive group (N stage, P=0.072; M stage, P=0.759; Fuhrman’s nuclear grade, P=0118). The MSH2-negative group showed decreased rates of recurrence-free survival, progression-free survival and overall survival, without statistically significant results (P=0.232, P=0.268 and P=0.311, respectively). MSH2 protein expression may be a useful marker for predicting TNM stage and prognosis and, thus, MSH2 may be a prognostic factor in clear cell RCC.

Abstract
Nodular fasciitis of the breast is a rare, benign, proliferative disease characterized by sudden onset and rapid growth. It can clinically and radiologically mimic breast cancer. We present imaging findings from two cases of nodular fasciitis that initially manifested as palpable masses. Sonographically, they appeared as irregular, not-circumscribed hypoechoic nodules. The diagnosis of nodular fasciitis was made by US-guided core needle biopsies. US-guided vacuum-assisted excision was subsequently performed in the first case, while the second resolved via spontaneous regression.

Abstract
On the basis of large cardiovascular clinical trials of lipid-lowering agents that showed a considerable decrease in the incidence of primary melanomas in the active agent arm, we have carried out a randomized, double-blind clinical trial examining the impact of lovastatin on various biomarkers of melanoma pathogenesis. Subjects with at least two clinically atypical nevi were randomized to receive oral lovastatin or placebo for a 6-month period. Clinical, histopathologic, and molecular biomarkers were evaluated for change in the two groups. Eighty subjects were randomized, evaluable, and included in the analyses. Lovastatin showed no benefit in comparison with placebo in the primary endpoint of decreasing the level of histopathologic atypia, nor in any of the secondary endpoints of decreasing clinical atypia, impact on nevus number, nor in showing significant changes in any of the molecular biomarkers. There were no significant differences in adverse event profiles for lovastatin compared with placebo. The lovastatin arm did show a significant and considerable decrease in total serum cholesterol and serum low-density lipoprotein (LDL) levels compared with placebo, an expected result. This finding bolsters confidence in subject compliance. Given the results of this trial, it is concluded that if lovastatin were to lower the incidence of melanoma, it would appear not to be doing so by reversing atypia of precursor atypical nevi over the 6-month time frame studied. Further research into the pathogenesis of melanoma and in other potential chemopreventive agents is needed.

Abstract
54 Background: Tumor associated macrophages (TAMs) are major components of tumor environment, and polarized into M1 and M2 type. M1 has been known as antitumorigenic, whereas M2 as protumorigenic. M2 have a significant role in tumor progression by promoting tumor cell invasion, migration and angiogenesis. We evaluated the M2 macrophages to investigate its importance in predicting clinical outcome or prognosis, and the relationship between M2 and angiogenesis in patients with gastric cancer. Methods: Formalin-fixed, paraffin-embedded blocks were obtained from the 88 patients with gastric cancer. CD163+ TAMs and CD105+ vessels were evaluated by immunohistochemical staining and the extent of CD163+ TAMs in tumor were divided into three groups: (A) infiltrated TAMs in cancer cell nest (nest TAMs); (B) infiltrated TAMs in tumor stroma (stroma TAMs); and (C) infiltrated TAMs along the invasive margin of a tumor (margin TAMs). Results: The increased stroma and margin TAMs (>72 and >102, respectively) were closely correlated with lymph node metastasis, TNM stage and lymphatic invasion (p<0.05 in 3 factors) and positive correlation existed between the stroma and margin TAMs (p<0.001). Disease-free survival rate analyzed using the Kaplan– Meier method was significantly lower in patient with high stroma and margin TMAs than patient with low stroma and margin TAMs (p=0.0039 and 0.0499, respectively). CD105+ vessels showed significant correlation with lymph node metastasis and lymphatic invasion.(p=0.006 and p<0.0001, respectively) Stromal, marginal and nest TAMs were positively correlated with CD105+ vessels (p=0.001). Conclusions: M2 infiltration in tumor stroma and tumor margin in gastric cancer showed relationship with aggressive phenotypes such as lymph node metastasis, TNM stage and lymphatic invasion and was correlated with angiogenesis. This study supports the view that the adverse prognostic impact of M2 involves tumor angiogenesis in gastric cancer.

Abstract
Human epidermal growth factor receptor 2 (HER2) status is useful for predicting response to trastuzumab. Fluorescence in situ hybridization (FISH) for HER2 gene amplification is accurate but limited because of cost, the need for fluorescence microscopy, the limited assessment of histology, and the fading of its signal over time. Dual-color in situ hybridization (Dual ISH) is fully automated, is viewable by bright-field microscopy, has a stable signal, and has separate colors for HER2 and chromosome 17 signals. HER2 immunohistochemistry (IHC), FISH, and Dual ISH were performed on 101 breast cancer cases. Sixteen of 17 cases with 3+ HER2 by IHC showed gene amplification by FISH, and 15 showed amplification by Dual ISH. Three of the 2+ IHC cases were either amplified or equivocal by Dual ISH. None of the IHC-negative cases were amplified by either FISH or Dual ISH. Dual ISH agreed with FISH in 93% of cases. Among the 6 discrepancies, 4 were for an equivocal result for 1 test compared with either a positive or a negative result for the other test. The average differences in readings between Dual ISH and FISH in the discrepant cases were only 0.02, with a range of -1.37 to 1.85. Turnaround time for FISH as a send-out test from test ordering to reporting averaged 8.27 workdays, whereas the turnaround time for Dual ISH performed in-house averaged 4.94 workdays (P < .0000001). Our results indicated that automated Dual ISH is a useful method for evaluating HER2 status in a clinical setting.

Abstract
Glioma tumor-suppressor candidate region gene2 (GLTSCR2) is a recently identified nucleolus-localized protein participating in the regulation of cell cycle progression and apoptosis. Down-regulation of GLTSCR2 in several types of cancers and increased transforming activity in GLTSCR2-downregulated cancer cells indicated its tumor suppressive potential. The aim of this study was to evaluate GLTSCR2 expression in breast cancer and to investigate the question of whether reduced expression of GLTSCR2 may have any pathological significance in breast cancer development or progression. In this study, we performed quantitative RT-PCR and immunohistochemistry to evaluate the expression of GLTSCR2 and relevance with clinicopathological factors in the invasive ductal carcinoma (IDC). GLTSCR2 expression was reduced in 48% of IDC (n=426) by a semi-quantitative scoring system using tissue microarray. GLTSCR2 mRNA was significantly reduced by 0.16 fold in 15 out of 17 (88%) cases of IDC. Reduction of GLTSCR2 was significantly correlated with increased histological grade (p<0.005), increased tumor size (p<0.001), axillary lymph node involvement (p<0.001) and decreased disease free survival (p<0.025). In addition, we show that upregulation of GLTSCR2 decreases the invasive potential of breast cancer cells. Taken together, our data suggest that GLTCR2 may play a role in the tumorigenesis, progression and biological behavior in breast cancer.

Abstract
Development of biliary casts is very unusual, especially in patients who have not undergone liver transplantation. Variable causes of biliary cast formation in nonliver transplantation patients have been suggested. However, stasis of bile flow and/or gallbladder hypocontractility is known to eventually result in the promotion of biliary sludge and subsequent cast formation. Here we present one case of biliary cast syndrome, which developed in a nonliver transplant patient who had biliary sludge for a long period of time, providing evidence that long-standing biliary sludge may lead to cast formation.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily involving the spine and sacroiliac joint and rarely the kidneys. This study aimed to define the clinical and histological features and biology of renal disease in AS. We reviewed the medical records of 681 patients diagnosed with AS from November 2008 to November 2009. Baseline characteristics and laboratory and urinalysis results were reviewed. We identified patients with proteinuria or hematuria and analyzed their risk factors. After providing informed consent, 6 patients underwent a renal biopsy to determine the cause of proteinuria or hematuria. Of the 681 enrolled patients, 547 were men and 134 were women; 81 % were HLA B27 positive, and 8 % had abnormal urinalysis findings (proteinuria, 5.9 %; hematuria, 2.8 %; both, 0.7 %). Incidences of peripheral arthritis and uveitis were 29 % and 18.6 %, respectively. Immunoglobulin (Ig)A and uric acid levels were significantly different between patients with and without proteinuria. Erythrocyte sedimentation rate (ESR), total cholesterol, creatinine, and C-reactive protein (CRP) levels were not statistically significantly different between the 2 groups nor were there any significant differences in IgA, uric acid, ESR, total cholesterol, creatinine, and CRP levels between patients with and without hematuria. Six patients who had >1 g/day proteinuria underwent a renal biopsy; 2 were diagnosed with IgA nephropathy, 1 with amyloidosis, and 3 with non-specific glomerulonephropathy. In the amyloidosis patient, severe proteinuria was the dominant feature. For patients with renal amyloidosis and other forms of glomerulonephritis who initially had normal creatinine levels, tumor necrosis factor (TNF)-alpha blocker therapy resolved proteinuria, but this was not the case for patients with initial renal insufficiency. Renal involvement is not a rare complication of AS, and prognoses differ depending on kidney pathology. Serum levels of uric acid and IgA may predict renal involvement in AS. In cases where abnormal urine sediment is identified, renal biopsy is required to determine prognosis and decide the treatment protocol. Baseline serum creatinine level is important for predicting treatment response.

Abstract
Hu antigen R (HuR) is a member of the human family of embryonic-lethal, abnormal vision-like proteins, which serves as an mRNA-binding protein. In the cytoplasm, HuR can stabilize the mRNA of cyclooxygenase-2 (COX-2), an enzyme that catalyses the synthesis of prostaglandins and is associated with promotion of carcinogenesis and tumor cell resistance to apoptosis. Intracellular (cytoplasmic and nuclear) localization of survivin has a prognostic significance as an apoptosis inhibitor and a regulator of cell division in tumors. Patients with 151 squamous cell carcinomas and 93 adenocarcinomas underwent lobectomy or pneumonectomy with hilar and mediastinal lymph node sampling. Paraffin-embedded tumor sections were retrieved for evaluation of nuclear and cytoplasmic staining of survivin and HuR, and cytoplasmic staining of COX-2. In squamous cell carcinomas, COX-2 expression was correlated with a difference of survivin (cytoplasmic-nuclear; P=0.004), cytoplasmic HuR (P=0.018), total HuR (cytoplasmic+nuclear; P=0.009), and difference of HuR (P=0.020). COX-2 was inversely correlated with nuclear survivin (P=0.006). In a univariate analysis by log-rank test, survival was associated with cytoplasmic survivin (adenocarcinoma, P<0.001; squamous cell carcinoma, P=0.005), difference of survivin (adenocarcinoma, P<0.001; squamous cell carcinoma, P=0.014), and COX-2 (squamous cell carcinoma, P=0.001). Survival was inversely associated with nuclear survivin (adenocarcinoma, P=0.006, squamous cell carcinoma, P=0.014). In a multivariate survival analysis, cytoplasmic survivin (adenocarcinoma, P=0.002; squamous cell carcinoma, P=0.015) and COX-2 (squamous cell carcinoma, P=0.020) were determined as independent prognostic factors. Cytoplasmic HuR expression is associated with COX-2 expression in squamous cell carcinomas. The expression of COX-2 in squamous cell carcinomas, and cytoplasmic survivin in adenocarcinomas and squamous cell carcinomas could be useful independent prognostic markers.

Abstract
Beclin-1 is a Bcl-2-interacting protein, and it may delay cell cycle progression and induce autophagy. The function and expression of Beclin-1 and Bcl-2 in squamous cell carcinoma and adenocarcinoma of the lung remain largely unknown. Herein, we investigated the expression of Beclin-1 and Bcl-2 in squamous cell carcinoma and adenocarcinoma of the lung. Tissue samples from 262 cases were used in this study. Immunohistochemical staining for Beclin-1 and Bcl-2 were conducted using a tissue microarray. In squamous cell carcinoma, Beclin-1 expression was strongly positive in 48 (28.6%) of 168 samples, it was moderately positive in 42 (25.0%) of 168 samples, and it was negative or weakly positive in 78 (46.4%) of 168 samples. In adenocarcinoma, Beclin-1 expression was strongly positive in 26 (27.7%) of 94 samples, it was moderately positive in 27 (28.7%) of 94 samples, and it was negative or weakly positive in 41 (43.6%) of 94 samples. Beclin-1 expression was inversely correlated with the tumor size and the primary tumor stage (pT) in both types of tumor. Especially, the TNM stage of adenocarcinoma was inversely correlated with Beclin-1 expression. Our results suggest that a progressively reduced Beclin-1 expression is correlated with the primary tumor growth of squamous cell carcinoma and adenocarcinoma of the lung.

Abstract
We report a rare case of pancreatic carcinosarcoma in a 48-year-old man. An abdominal ultrasound scan incidentally detected a large heterogeneous mass in the left upper quadrant. CT and MRI scans indicated a rapidly growing unilocular cystic mass in the pancreatic tail. Grossly, the resected pancreatic mass measured 7×5×5 cm and consisted of a unilocular cystic lesion that had several solid mural nodules. Microscopically, the cystic wall showed two carcinomatous components, mucinous cystadenocarcinoma and anaplastic carcinoma. The solid lesion predominantly consisted of pleomorphic spindle cells arranged in interlacing fascicles which had infiltrated the adjacent pancreatic parenchyma. In some areas of this sarcomatous component, anaplastic carcinoma cells intermingled with or transformed into spindle cells. Immunohistochemically, the carcinomatous components were strongly positive for epithelial markers, and transforming anaplastic carcinoma cells were immunoreactive for both epithelial markers and vimentin; in contrast, the sarcomatous component was strongly positive for only vimentin. Additionally, an identical mutation (G to A transition) at codon 12 of K-ras gene and concordant immunoreactivity for p53 protein were detected in the carcinomatous and sarcomatous components. These findings suggested that the pancreatic carcinosarcoma could be of monoclonal origin, and that the sarcomatous component might have arisen from metaplastic transformation of the carcinomatous component.

Abstract
Beclin-1 has emerged as an autophagy gene in a variety of human carcinomas. The aim of this study was to evaluate beclin-1 expression and to determine its prognostic significance in patients with pancreatic ductal adenocarcinoma (PDA). We performed immunohistochemical staining for beclin-1 in 63 cases of PDA. We investigated whether beclin-1 expression correlated with clinicopathologic characteristics and patient outcomes. Beclin-1 expression was absent in normal pancreatic islet cells, acinar cells, and ductal epithelial cells. In contrast, in PDA, beclin-1 showed positive immunoreactivity in 14 of 63 (22.2%) PDA cases, while the remaining 49 (77.8%) PDA cases exhibited negative beclin-1 expression. We found significant associations between increased beclin-1 expression and the absence of lymphatic invasion (P = 0.032) and low rate of distant metastasis (P = 0.001). Univariate analysis of survival showed that the median distant metastasis-free survival of beclin-1-negative PDA patients (10 months) was significantly shorter than that of beclin-1-positive PDA patients (21 months; P = 0.031). Our results suggest that increased beclin-1 expression plays a role in the inhibition of PDA progression.

Abstract
AIMS Raf-1 kinase inhibitor protein (RKIP) has emerged as a significant metastatic suppressor in a variety of human cancers. The aim of this study was to evaluate RKIP expression and to determine its association with metastasis and prognostic significance in pancreatic cancer patients. METHODS Immunohistochemical staining for RKIP was performed on 63 cases of pancreatic ductal adenocarcinoma (PDAC). We investigated whether RKIP expression correlated with clinicopathological parameters and patient outcomes. RESULTS The islet cells, acinar cells and ductal epithelial cells of normal pancreas consistently showed strong RKIP immunoreactivity. In contrast, in PDAC, RKIP was lost in 57.1% (37/63) of cases. Loss of RKIP expression was significantly associated with the presence of nodal (p=0.001) and distant (p=0.010) metastases and a higher stage group (p=0.012). Univariate analysis for distant metastasis-free survival (DMFS) showed that the median DMFS of RKIP negative PDAC patients (10 months) was significantly shorter than that of RKIP positive PDAC patients (17 months; p=0.009). Multivariate analysis also revealed that loss of RKIP expression was an independent predictor of worse DMFS in PDAC patients (p=0.015). CONCLUSIONS Our results strongly suggest that RKIP is a metastasis suppressor in PDAC.
