Abstract
Pancreatic Adenocarcinoma (PDAC) is one of the most deadly malignant tumors worldwide. A variety of mechanisms are involved in PDAC biological behaviors, of which, the mechanisms of immune escape may be a pivotal hallmark. HLA-G is a tolerant molecule implicated in tumor escape and serves as a prognostic biomarker in tumors. Our study evaluated the expression of HLA-G in PDAC and explored its clinical significance. In a cohort of 122 PDAC patients, 78 patents (63.9%) exhibited high level of HLA-G tumor tissues. Multivariate analysis suggested that HLA-G level was an independent predictor for OS (HR = 3.894, 95% CI = 2.380-6.370, p <0.001). High level of HLA-G significantly correlated with PDAC aggressive features, such as more advanced stage (TNM Stage II) (p<0.001), extrapancreatic infiltration (T3 stage) (p<0.001), lymph node involvement (p=0.019) and poor differentiation (p=0.010). In western blot analysis, almost all of the tumor cell lines (5/6) expressed high levels of HLA-G. In ELISA analysis, the level of plasma sHLA-G in PDAC patients were significantly increased than in healthy control (P=0.0037). Further analysis revealed the level of sHLA-G inversely related to numbers of peripheral activated T cells (CD8+CD28+ T cells), which may indicate that sHLA-G inactivates T cell responses resulting in tumor immune escape. In conclusion, tumor-derived HLA-G may indicate the mechanism of immune escape and impaired PDAC clinical outcome, especially in early-stage patients, which may also be a potential therapeutic target.

Abstract
The aim of the current study was to explore mechanisms of SEMA3B gene expression and its clinical significance in glioma, and provide a theoretical foundation for investigating individualized treatment in glioma. Paraffin-embedded tissues from 43 patients with a confirmed clinical diagnosis of glioma following neurosurgery at the First Affiliated Hospital of Zhengzhou University from December 2013 to April 2014 were selected randomly. An additional three normal brain tissues were obtained following encephalic decompression excision due to acute craniocerebral injury in the same period, which were used as the control group. Immunohistochemical staining for vascular endothelial growth factor was performed on the glioma tissues from the 43 patients. Genomic DNA was extracted for bisulfate conversion and sequencing. SEMA3B was fully expressed in the three normal brain tissues, and incompletely expressed in the 43 glioma tissues, with a lack of expression in 48.8% (21/43) of samples. Moreover, 58% of high-grade gliomas (grade III and IV) lacked SEMA3B expression, which was significantly more than those that lacked expression (20%) in low-grade gliomas (grade I and II), indicating that, as the clinical pathological grade increased, SEMA3B expression decreased. The occurrence and development of malignant tumors is a product of multiple genes and other factors. Here, we provide theoretical basis for glioma development and prognosis involving DNA-methylation driven silencing of SEMA3B, and thus, SEMA3B is a potential target for directed treatments against glioma.

Abstract
BACKGROUND High profile safety failures have demonstrated that recognising early warning signs of clinical and physiological deterioration can prevent or reduce harm resulting from serious adverse events. Early warning scoring systems are now routinely used in many places to detect and escalate deteriorating patients. Timely and accurate vital signs monitoring are critical for ensuring patient safety through providing data for early warning scoring systems, but little is known about current monitoring practices. OBJECTIVE To establish a profile of nurses' vital signs monitoring practices, related dialogue, and adherence to health service protocol in New South Wales, Australia. METHODS Direct observations of nurses' working practices were conducted in two wards. The observations focused on times of the day when vital signs were generally measured. Patient interactions were recorded if occurring any time during the observation periods. Participants (n=42) included nursing staff on one chronic disease medical and one acute surgical ward in a large urban teaching hospital in New South Wales. RESULTS We observed 441 patient interactions. Measurement of vital signs occurred in 52% of interactions. The minimum five vital signs measures required by New South Wales Health policy were taken in only 6-21% of instances of vital signs monitoring. Vital signs were documented immediately on 93% of vitals-taking occasions and documented according to the policy in the patient's chart on 89% of these occasions. Nurse-patient interactions were initiated for the purpose of taking vital signs in 49% of interactions, with nurse-patient discourse observed during 88% of all interactions. Nurse-patient dialogue led to additional care being provided to patients in 12% of interactions. CONCLUSION The selection of appropriate vital signs measured and responses to these appears to rely on nurses' clinical judgement or time availability rather than on policy-mandated frequency. The prevalence of incomplete sets of vital signs may limit identification of deteriorating patients. The findings from this study present an important baseline profile against which to evaluate the impact of introducing continuous monitoring approaches on current hospital practice.

Abstract
BACKGROUND We sought to determine whether the substantial benefits of topical nitroglycerin with first-line, platinum-based, doublet chemotherapy in advanced nonsmall-cell lung cancer (NSCLC) seen in a phase II trial could be corroborated in a rigorous, multicenter, phase III trial. PATIENTS AND METHODS Patients starting one of five, prespecified, platinum-based doublets as first-line chemotherapy for advanced NSCLC were randomly allocated treatment with or without nitroglycerin 25 mg patches for 2 days before, the day of, and 2 days after, each chemotherapy infusion. Progression-free survival (PFS) was the primary end point. RESULTS Accrual was stopped after the first interim analysis of 270 events. Chemotherapy was predominantly with carboplatin and gemcitabine (79%) or carboplatin and paclitaxel (18%). The final analysis included 345 events in 372 participants with a median follow-up of 33 months. Topical nitroglycerin had no demonstrable effect on PFS [median 5.0 versus 4.8 months, hazard ratio (HR) = 1.07, 95% confidence interval (CI) 0.86-1.32, P = 0.55], overall survival (median 11.0 versus 10.3 months, HR = 0.99, 95% CI 0.79-1.24, P = 0.94), or objective tumor response (31% versus 30%, relative risk = 1.03, 95% CI 0.82-1.29, P = 0.81). Headache, hypotension, syncope, diarrhea, dizziness, and anorexia were more frequent in those allocated nitroglycerin. CONCLUSION The addition of topical nitroglycerin to carboplatin-based, doublet chemotherapy in NSCLC had no demonstrable benefit and should not be used or pursued further.

Abstract
To enable preventive measures to be designed, it is important to identify modifiable distal and proximal factors underlying doping behavior. This study investigated aspects of the prototype willingness model in relation to doping. A cross-sectional study was conducted involving 729 competitive athletes. Following ethical approval, athletes (mean age = 28.8 ± 10.1 years; 63% male) completed an online questionnaire, which assessed doping-related attitudes, norms, prototype perceptions, outcome expectancies, and behavioral willingness. Using hierarchical multiple regression analysis, 54.4% of the total variance in willingness to dope was explained. Specifically, past doping, attitudes, and favorability of performance enhancing substance user prototypes were the strongest unique predictors of willingness to dope. Athletes appeared most willing to dope if they were to suffer an injury, a dip in performance, or think others are doping and getting away with it. National-level athletes displayed significantly greater willingness to dope (Kruskal-Wallis γ2 = 35.9, P < 0.001) and perceived themselves as significantly more similar to a doper (Kruskal-Wallis γ2 = 13.4, P = 0.004) than athletes competing at any other level. The findings highlight the importance of extending anti-doping provision beyond elite-level sport and the need to target athletes' doping-related perceptions.

Abstract
We have developed a high-current laser ion source for induction accelerators. A copper target was irradiated by a frequency-quadrupled Nd:YAG laser (266 nm) with relatively low intensities of 10(8) W/cm(2). The laser-produced plasma supplied a large number of Cu(+) ions (∼10(12) ions/pulse) during several microseconds. Emission spectra of the plasma were observed and the calculated electron temperature was about 1 eV. An induction voltage adder extracted high-current ion beams over 0.5 A/cm(2) from a plasma-prefilled gap. The normalized beam emittance measured by a pepper-pot method was smaller than 1 π mm mrad.

Abstract
Accumulating evidence indicates that microRNAs (miRNAs) have great potential as tumor biomarkers and therapeutic agents owing to their functions in tumorigenesis and cancer progression. Aberrant expression of miR-1247 has been found in several cancers and is predicted to play an important role in the pathological processes of pancreatic cancer by miRNA-regulated network analysis. We investigated the expression profile of miR-1247 in pancreatic cancer tissue microarray by in situ hybridization and found that miR-1247 was significantly down-regulated in pancreatic cancer tissues compared to matched benign tissues. High levels of miR-1247 expression were positively correlated with higher overall and recurrence free survival in pancreatic cancer patients, while negatively correlated with tumor grade. Using in vitro and in vivo models, we demonstrated that increased expression of miR-1247 inhibited proliferation, tumorigenicity, colony formation and triggered G0/G1 cell cycle arrest in pancreatic cancer cells. Moreover, we confirmed that neuropilin1 (NRP1) and neuropilin2 (NRP2) are direct targets of miR-1247 by western blot and luciferase reporter assay. Further studies indicated that low dose all trans retinoic acid (ATRA) can induce redifferentiation and restoration of miR-1247 in pancreatic cancer cells. These findings suggest that miR-1247, a novel tumor suppressor, can act as a potential biomarker and therapeutic agent for pancreatic cancer.

Abstract
The objective of the study was to assess the relationship between hypertension and risk of depression. The relationship between hypertension and depression has been discussed for a long time, but the results are controversial. Studies were searched from PubMed and Cochrane up to 24 March 2014. Any prospective cohort study, which possibly reported the relationship between hypertension and depression, was included. The random effect model was used to calculate the pooled relative risk (RR). Finally, five prospective cohort studies were included for analysis, with a total of 9647 participants involved. Our meta-analysis does not support that hypertension is probably a risk factor of depression. The pooled RR was 1.16 (95% confidence interval: 0.91, 1.42) when those exposed to hypertension were compared with those who were not. Subgroup analysis, sensitivity analysis and publication bias test suggested that the overall result of this analysis was robust. Further studies are needed to exclude the effects of other confounding factors.

Abstract
Mitochondrial dysfunction contributes to the development of muscle disorders, including muscle wasting, muscle atrophy and degeneration. Despite the knowledge that oxidative stress closely interacts with mitochondrial dysfunction, the detailed mechanisms remain obscure. In this study, tert-butylhydroperoxide (t-BHP) was used to induce oxidative stress on differentiated C2C12 myotubes. t-BHP induced significant mitochondrial dysfunction in a time-dependent manner, accompanied by decreased myosin heavy chain (MyHC) expression at both the mRNA and protein levels. Consistently, endogenous reactive oxygen species (ROS) overproduction triggered by carbonyl cyanide 4-(trifluoromethoxy) phenylhydrazone (FCCP), a mitochondrial oxidative phosphorylation inhibitor, was accompanied by decreased membrane potential and decreased MyHC protein content. However, the free radical scavenger N-acetyl-L-cysteine (NAC) efficiently reduced the ROS level and restored MyHC content, suggesting a close association between ROS and MyHC expression. Meanwhile, we found that both t-BHP and FCCP promoted the cleavage of optic atrophy 1 (OPA1) from the long form into short form during the early stages. In addition, the ATPase family gene 3-like 2, a mitochondrial inner membrane protease, was also markedly increased. Moreover, OPA1 knockdown in myotubes was accompanied by decreased MyHC content, whereas NAC failed to prevent FCCP-induced MyHC decrease with OPA1 knockdown, suggesting that ROS might affect MyHC content by modulating OPA1 cleavage. In addition, hydroxytyrosol acetate (HT-AC), an important compound in virgin olive oil, could significantly prevent t-BHP-induced mitochondrial membrane potential and cell viability loss in myotubes. Specifically, HT-AC inhibited t-BHP-induced OPA1 cleavage and mitochondrial morphology changes, accompanied by improvement on mitochondrial oxygen consumption capacity, ATP productive potential and activities of mitochondrial complex I, II and V. Moreover, both t-BHP- and FCCP-induced MyHC decrease was sufficiently inhibited by HT-AC. Taken together, our data provide evidence indicating that mitochondrial dysfunction-associated OPA1 cleavage may contribute to muscle degeneration, and olive oil compounds could be effective nutrients for preventing the development of muscle disorders.

Abstract
Following the UK Academy of Medical Royal Colleges Report on seven day consultant present care, the Royal College of Physicians and Surgeons of Glasgow held a symposium to explore clinicians' views on the ways in which clinical care should best be enhanced outside 'normal' working hours. In addition, a survey of members and fellows was undertaken to identify the tests which would make the greatest impact on care out of hours. Key messages were: (a) that seven-day consultant delivered care would not achieve the desired benefit to patient care if introduced in isolation from other inter-relating factors. These include alternatives to hospital admission, enhanced nursing support, increased junior medical, pharmacy, social care and ambulance availability and greater access to selected diagnostic services; (b) that the care of hospital inpatients is a service which is one part of the totality of secondary care provision. Any significant change in the deployment of staff for inpatient care must be carefully managed so as not to result in a reduced quality of care provided by the rest of the system.

Abstract
OBJECTIVE Schizophrenia is a severe mental disorder. Its prevalence appears inconsistent in different regions of China; thus, we conducted this meta-analysis to estimate the prevalence of schizophrenia in mainland China. METHOD Studies on the prevalence of schizophrenia in mainland China were identified from electronic databases up to July 2013. Meta-analysis was used for prevalence of schizophrenia estimate. RESULTS For lifetime prevalence of schizophrenia, prevalence of 5.44 per 1000 (overall), 5.33 per 1000 (males), 5.51 per 1000 (females), 6.60 per 1000 (urban) and 4.73 per 1000 (rural) were estimated; there was no significant difference between males and females, while prevalence for urban dwellers was higher than for rural (OR=1.44, 95%CI: 1.30-1.59). For point prevalence of schizophrenia, prevalence of 4.62 per 1000 (overall), 4.63 per 1000 (males), 4.95 per 1000 (females), 5.15 per 1000 (urban) and 4.44 per 1000 (rural) were estimated; no statistical difference was found in males and females, but prevalence for urban dwellers was higher than for rural (OR=1.20; 95%CI: 1.02-1.41). CONCLUSION The prevalence estimate results were consistent with the international prevalence estimate of schizophrenia in mainland China. There was no significant difference between males and females, while prevalence for urban dwellers was higher than for rural.

Abstract
Renal growth, particularly hypertrophy, is a feature of diabetic nephropathy (DN). Adiponectin, an adipocyte-derived hormone, is an important regulator of cell proliferation. Recent studies have suggested that adiponectin has a protective effect in the kidney. The purpose of this study was to investigate the therapeutic effects and the underlying mechanisms of adiponectin in early DN. Mouse mesangial cells (MMCs) were cultured in media containing different concentrations of platelet-derived growth factor-BB (PDGF-BB) with or without adiponectin. MMC proliferation and expression of type IV collagen, laminin, and fibronectin were investigated. Streptozotocin-induced diabetic mice were injected intravenously with recombinant lentivirus encoding the mouse adiponectin gene (Lenti-Acdc-IRES-EGFP). Urinary microalbumin, serum adiponectin level, and expression of proliferating cell nuclear antigen, type IV collagen, laminin, and fibronectin were determined. Adiponectin inhibited the increases in MMC proliferation and expression of type IV collagen, laminin, and fibronectin induced by PDGF-BB. Adiponectin also effectively reduced renal cell proliferation and expression of type IV collagen, laminin, and fibronectin when it was introduced in vivo by lentivirus-mediated gene transfer. These findings suggest that adiponectin exerts renoprotective effects by inhibiting renal cell proliferation and reducing synthesis of extracellular matrix proteins, thus suppressing the development and progression of DN.

Abstract
Lipoapoptosis is the main form of pancreatic β-cell death in diabetes. Adiponectin is an adipocyte-derived hormone, which has anti-apoptosis effect in numerous cells. The present study was designed to explore the role of the 'extrinsic' (death receptor-induced) and the 'intrinsic' (mitochondrial) pathways in pancreatic β-cell lipoapoptosis and the anti-apoptosis effect of adiponectin on pancreatic β-cells. Palmitate (0.4 mmol/l) or oleate (0.4 mmol/l) was used to induce the apoptosis of Min 6 cells for 24 h. Z-LETD-FMK or Z-IEHD-FMK (40 μM) was used to inhibit the activity of caspase-8 or -9. When adiponectin was used, Min 6 cultures were pretreated in the absence or presence of fAd (5 μg/ml) for 2 h and then subjected to palmitate for 24 h. Apoptosis was evaluated using Annexin V-Cy3 kit. The expression levels of cleaved caspase-3, -8, -9, B-cell lymphoma 2 (BCL-2), and Bax were examined by Western blotting. Palmitate-induced pancreatic β-cell apoptosis was accompanied by the activation of caspase-8, -9, and -3. Blockade of caspase-9 rather than caspase-8, showed an inhibitory effect on caspase-3 activation. Moreover, adiponectin treatment prevented palmitate-induced apoptosis by inhibition of caspase-9 activation, but not of caspase-8, and induced an upregulation of BCL-2 and a downregulation of Bax in protein level. Both extrinsic and intrinsic pathways are activated in pancreatic β-cell lipoapoptosis, and the intrinsic apoptosis pathway is the major one. Adiponectin prevents pancreatic β-cells from apoptosis by inhibition of intrinsic apoptosis pathway via regulation of the BCL2 family. Therefore, protection of intrinsic apoptosis pathway is a potential therapeutic strategy for diabetes.

Abstract
Nondestructive studies of physiological processes in agronomic products require increasingly higher spatial and temporal resolutions. Nuclear Magnetic Resonance (NMR) imaging is a non-invasive technique providing physiological and morphological information on biological tissues. The aim of this study was to design a robust and accurate quantitative measurement method based on NMR imaging combined with contrast agent (CA) for mapping and quantifying water transport in growing cherry tomato fruits. A multiple flip-angle Spoiled Gradient Echo (SGE) imaging sequence was used to evaluate the intrinsic parameters maps M0 and T1 of the fruit tissues. Water transport and paths flow were monitored using Gd(3+)/[Fe(CN)6](3-)/D-mannitol nanoparticles as a tracer. This dynamic study was carried out using a compartmental modeling. The CA was preferentially accumulated in the surrounding tissues of columella and in the seed envelopes. The total quantities and the average volume flow of water estimated are: 198 mg, 1.76 mm(3)/h for the columella and 326 mg, 2.91 mm(3)/h for the seed envelopes. We demonstrate in this paper that the NMR imaging technique coupled with efficient and biocompatible CA in physiological medium has the potential to become a major tool in plant physiology research.

Abstract
Type 2 diabetes mellitus (T2DM) is a risk factor for heart disease. However, the mechanisms of T2DM involvement in cardiac complications are still unclear. In the present study, we investigated mitochondria-related mechanisms underlying the pathogenesis of myocardial disorders in diabetic Goto-Kakizaki (GK) rats. We found that remarkable myocardial mitochondrial deficiency and dysfunction as well as oxidative stress occurred in the heart of GK rats. In addition, our results suggested that the loss of mitochondria was in response to elevated autophagy and upstream FoxO factors in diabetic myocardium. More importantly, (-)-epigallocatechin-3-gallate (EGCG), a polyphenol derived from green tea, successfully improved mitochondrial function and autophagy in the heart of GK rats. Our findings revealed that diabetes-associated myocardial mitochondrial deficiency and dysfunction was associated with enhanced autophagy in myocardium, and EGCG might be a potential agent in preventing and treating myocardial disorders involved in diabetes.

Abstract
Simple liver cysts are common, rarely causing significant morbidity or mortality. Budd–Chiari syndrome (BCS) is caused by obstruction of hepatic venous outflow and is the leading cause of postsinusoidal liver failure. We present a rare case of BCS caused by a simple hepatic cyst. A 16cm × 16cm liver cyst was found on computed tomography of a 66-year-old woman presenting with abdominal pain. The cyst had become infected, thus enlarged, exerting mass effect with almost complete compression of the inferior vena cava. Shortly after admission, the patient developed acute liver failure, with deranged clotting and hepatic encephalopathy requiring full organ support on the intensive care unit. Cardiac output studies showed a low cardiac index of 1.4l/min/m2. An emergency laparotomy with fenestration of the cyst and drainage of 2l of purulent material led to a full recovery. Intraoperative cystic fluid aspirates later confirmed no evidence of Echinococcus. Histology confirmed a simple cyst. Liver biopsies showed severe, confluent, bridging necrosis, without background parenchymal liver disease. Acute BCS due to rapid compression of all major hepatic veins leading to fulminant hepatic failure is rare. Our case highlights a clinically significant complication of a simple liver cyst of which clinicians should be aware when managing these ‘innocent’ lesions.

Abstract
Pancreatic cancer has an extremely poor prognosis mainly due to lack of effective treatment options. Radiotherapy is mostly applied to locally advanced cases, although tumor radioresistance limits the effectiveness. Profilin1, a novel tumor suppressor gene, was reported to be down-regulated in various cancers and associated with tumor progression. The objective of this study was to demonstrate how profilin1 affected pancreatic cancer radiosensitivity. We showed profilin1 was down-regulated in pancreatic cancer cells after exposure to radiation, and re-expression of profilin1 suppressed tumor cell viability and increased DNA damage following irradiation. Further studies revealed that up-regulation of profilin1 facilitated apoptosis and repressed autophagy induced by irradiation, which might sensitize pancreatic cancer cells to radiation treatment. Our findings may provide a novel therapeutic strategy for sensitizing pancreatic cancer to radiotherapy.

Abstract
AIM To retrospectively assess long-term survival benefit and safety of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in hepatocellular carcinoma (HCC) patients with portal vein tumour thrombosis (PVTT), and to evaluate factors that significantly affect outcomes of these patients. MATERIALS AND METHODS One hundred and thirty-four HCC patients (118 men and 16 women; mean age 54.8 years, range 26-79 years) with PVTT were retrospectively assessed. Patients were treated with TACE combined with RFA. Data analysed included patient demographics, liver volume, Child-Pugh score, and Cancer of the Liver Italian Programme (CLIP) score and imaging findings. Survival time (from occurrence of PVTT to last follow-up) was calculated using the Kaplan-Meier method, predictive factors and its correlation with survival was assessed using the multivariate Cox proportional hazards regression method. RESULTS The median overall survival (OS) time was 29.5 months (range 16.6-42.4 months), the 1, 3, and 5 year OS were 63%, 40%, and 23%. Cox hazards regression analysis revealed that functional remnant liver volume (FRLV), remnant liver volume (RLV)/total liver volume (TLV), radiation, tumour number, vascular endothelial growth factor (VEGF) distribution, and gross type were the only independent predictive factors of outcome (p = 0.039, 0.010, 0.009, 0.034, 0.031, and 0.000, respectively). CONCLUSION TACE combined with RFA was found to be an effective therapy, FRLV and RLV/TLV have close correlation with survival for HCC patients with PVTT type I, II, or partial III and Child-Pugh A or B.

Abstract
BACKGROUND Breast cancer is one of the most common malignancies in women. Genome-wide association studies have identified FGFR2 as a breast cancer susceptibility gene. Common variation in other fibroblast growth factor (FGF) receptors might also modify risk. We tested this hypothesis by studying genotyped single-nucleotide polymorphisms (SNPs) and imputed SNPs in FGFR1, FGFR3, FGFR4 and FGFRL1 in the Breast Cancer Association Consortium. METHODS Data were combined from 49 studies, including 53 835 cases and 50 156 controls, of which 89 050 (46 450 cases and 42 600 controls) were of European ancestry, 12 893 (6269 cases and 6624 controls) of Asian and 2048 (1116 cases and 932 controls) of African ancestry. Associations with risk of breast cancer, overall and by disease sub-type, were assessed using unconditional logistic regression. RESULTS Little evidence of association with breast cancer risk was observed for SNPs in the FGF receptor genes. The strongest evidence in European women was for rs743682 in FGFR3; the estimated per-allele odds ratio was 1.05 (95% confidence interval=1.02-1.09, P=0.0020), which is substantially lower than that observed for SNPs in FGFR2. CONCLUSION Our results suggest that common variants in the other FGF receptors are not associated with risk of breast cancer to the degree observed for FGFR2.
