Abstract
Chest pain experienced by patients with coronary artery disease can be partly due to gastroesophageal reflux-induced chest pain (GERP). Empirical proton pump inhibitor (PPI) therapy has been recommended as an initial clinical approach for treating GERP. However, PPI use may lead to some health problems. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) may represent a noninvasive and cost-effective approach for avoiding PPI misuse and for identifying the appropriate patients for the PPI trial test. The aim of this pilot study was to prospectively evaluate the association between GerdQ scores and PPI response in patients with coronary artery disease (CAD) and GERP to determine whether the GerdQ predicts the PPI response in patients with CAD and GERP and to further validate the clinical application value of the GerdQ. A total of 154 consecutive patients with potential GERP were recruited to complete a GerdQ with subsequent PPI therapy. Based on the PPI trial result, patients were divided into a PPI-positive response group and a PPI-negative response group. The difference in the GerdQ scores between the two groups was assessed. The receiver operating characteristic (ROC) curve of GerdQ score was drawn according to the PPI response as the gold standard. The ability of GerdQ to predict the PPI response was assessed. A total of 96 patients completed the entire study; 62 patients (64.6%) were assigned to the PPI-positive response group, and 34 patients (35.4%) to the PPI-negative response group. The GerdQ score of the PPI-positive response group (8.11 ± 3.315) was significantly higher than that of the PPI-negative response group (4.41 ± 2.743), and the difference was statistically significant (t = 5.863, P = 0.000). The ROC curve was drawn according to a PPI response assessment result with a score above 2 as the gold standard. The area under curve was 0.806. When the critical value of GerdQ score was 7.5, Youden index was up to 0.514, the diagnostic sensitivity was 0.661, and the diagnostic specificity was 0.853. A GerdQ score greater than 7.5 better predicts the response to the PPI trial therapy. There is a strong association between the GerdQ score and the response to PPI therapy. Higher GerdQ scores were predictive of a positive PPI response in CAD patients with GERP. The GerdQ may be a reasonable screening tool for GERP in patients with CAD who are prepared to accept PPI therapy.

Abstract
Electron beam interaction with high frequency structures (beyond microwave regime) has a great impact on future high energy frontier machines. We report on the generation of multimegawatt pulsed rf power at 91 GHz in a planar metallic accelerating structure driven by an ultrarelativistic electron bunch train. This slow-wave wakefield device can also be used for high gradient acceleration of electrons with a stable rf phase and amplitude which are controlled by manipulation of the bunch train. To achieve precise control of the rf pulse properties, a two-beam wakefield interferometry method was developed in which the rf pulse, due to the interference of the wakefields from the two bunches, was measured as a function of bunch separation. Measurements of the energy change of a trailing electron bunch as a function of the bunch separation confirmed the interferometry method.

Abstract
PURPOSE OF INVESTIGATION Genetic susceptibility of breast cancer has been shown to be modulated by inheritance of polymorphic genes. EGF-containing fibulin-like extracellular matrix protein 1 (EFEMP1) gene played an important role in many tumors, including lung cancer, hepatic carcinoma, and prostate cancer. In addition, it was importantly downexpressed in breast cancer. The present research aimed to assess the association between genetic variations of EFEMP1 and breast cancer risk. MATERIALS AND METHODS The authors genotyped 11 common tagging SNPs with an array platform including 960 cases and 972 cancer-free controls of Chinese women, according to the HapMap database based on the pairwise linkage disequilibrium (LD) r² threshold of 0.8, minor allele frequency of 0.05. RESULTS Three SNPs were significant associated with breast cancer (rs3791679, p = 0.016, OR = 1.21, 95% CI = 1.04-1.41; rs1346786, p = 0.005, OR = 1.31, 95% CI = 1.08 -1.59; rs727878, p = 0.002, OR = 1.29, 95%CI = 1.10-1.51). Multivariate logistic regression analysis revealed that, compared with wild-type carriers in a dominant model, a significantly increased breast cancer risk was associated with the three identified risk SNPs. Among the selected tagging SNPs, three haplotype blocks were identified, and the results of haplotype analysis were consistent with the single-locus analysis. The haplotype 'GG' in block 1 and haplotype 'AG' in block 2 were significantly associated with breast cancer, and had a 54% and 28% increased breast cancer risk respectively, compared with their corresponding noncarriers. CONCLUSIONS The present results suggested that the polymorphisms of EFEMP1 gene were associated with breast cancer and might contribute to the susceptibility of the progression of breast cancer in Chinese Han women. Individuals with the risk alleles might increase the risk of breast cancer.

Abstract
Osteosarcoma represents an aggressive type of bone malignancy that poses a significant health threat. The objective of the current study was to analyze the effect and mechanism of dihydroartemisinin (DHA) on the proliferation, metastasis and apoptosis of human osteosarcoma cells. A gradient concentration of DHA (15, 25 and 35 μmol.L-1) was used to stimulate the cells, along with control and Dimethyl sulfoxide (DMSO). The phenotypic outcomes were characterized using MTT assay, clone formation assay, Hoechst 33258 staining assay, luciferase reporter plasmid assay, Western blot and wound healing assay. In addition, IBM SPSS Statistics 18.0 software was applied for statistical analysis and all experimental data were expressed as mean ± s.d. Analysis of variance (ANOVA) was applied to compare the differences among multiple groups. Our results demonstrated that DHA inhibited the proliferation and metastasis of osteosarcoma cells and promoted the apoptosis in the cytomorphosis.

Abstract
In vitro data showed that immunoglobulin G (IgG) from lupus nephritis (LN) patients could bind to proximal renal tubular epithelial cells (PTEC), but the clinical relevance of such binding remained unclear. Binding of IgG and subclasses to PTEC was measured by cellular ELISA (expressed as OD index) in 189 serial serum samples from 23 Class III/IV ± V LN patients who had repeated renal flares (48 during renal flares, 141 during low level disease activity (LLDA)), and compared with 64 patients with non-lupus glomerular diseases (NLGD) and 23 healthy individuals. Total IgG PTEC-binding index was 0.34 ± 0.16, 0.29 ± 0.16, 0.62 ± 0.27 and 0.83 ± 0.38 in healthy controls, NLGD, LN patients during LLDA, and LN patients during nephritic flare, respectively (p < 0.001, LLDA vs. renal flare; p < 0.001, healthy controls or NLGD vs. LN during LLDA or renal flare). PTEC-binding index for IgG1 was 0.09 ± 0.05, 0.16 ± 0.12, 0.44 ± 0.34 and 0.71 ± 0.46 for the corresponding groups (p < 0.001, LLDA vs. renal flare; p < 0.001, healthy controls or NLGD vs. LN during LLDA or renal flare). Sixteen of 48 episodes (33.3%) of nephritic flare showed persistent PTEC-binding IgG seropositivity for more than 9.4 ± 3.1 months, despite clinical response to immunosuppressive treatment. Total IgG and IgG1 PTEC-binding correlated with anti-dsDNA level (r = 0.34 and 0.52, respectively, p < 0.001 for both), and inversely with C3 level (r = -0.26 and -0.50, respectively, p = 0.002 and<0.001). Sensitivity/specificity of PTEC-binding index in detecting renal flares was 45.8%/80.1% for total IgG (ROC AUC 0.630, p = 0.007) and 87.5%/35.5% for IgG1 (ROC AUC 0.615, p = 0.018). IgG1 PTEC-binding index correlated with tubulo-interstitial inflammation score in renal biopsy from corresponding patients. Our data suggested that total IgG and IgG1 PTEC-binding index in serum of LN patients correlate with serological activity, and in combination could predict renal flares. The correlation between IgG1 PTEC-binding and tubulo-interstitial inflammation suggests potential pathogenetic significance.

Abstract
Breast cancer, one of the most common malignant tumors in females, draws little attention because of its untypical symptoms and signs, so the disease is usually confirmed too late, in an advanced stage. Based on the detection of nuclear morphology parameters of luminal B breast cancer, this study explored how pathological features relate to estrogen receptor (ER) and progesterone receptor (PR) expression of human epidermal growth factor receptor-2 (HER2). A quantity of 354 breast cancer specimens with follow-up records from the department of pathology in the First Peoples Hospital of Nantong and the Tumor Hospital of Nantong were selected as research subjects. Nuclear parameters of specimens stained by hematoxylin and eosin were measured by imaging analysis software. It was found that breast cancer can be divided into four types, luminal B, luminal A, HER2 over-expression and basal-like type based on immunohistochemical results of three antibodies, i.e, ER, PR and HER2. A total of 113 patients (31.8%) were confirmed with luminal B breast cancer, mostly in histological stage II; the difference of nuclear morphology was of statistical significance between ER+/PR+ and ER-/PR- (P<0.05), and most ER-/PR- was histologically confirmed as stage III, with lower survival rate than ER+/PR+ (P<0.05). Among these four subtypes of breast cancer, luminal B had the lowest brain metastasis rate, while HER2 over-expression subtype was found with the highest rate of lung and pleura metastasis. Besides, luminal B possessed longer disease-free survival (DFS) than basal-like (P<0.05) and longer total survival (OS) than HER2 over-expression (P<0.05) and basal-like subtypes (P<0.05). It can be concluded that detection of ER, PR and HER2 in combination with nuclear morphology is beneficial to evaluate treatment and prognosis of breast cancer.

Abstract
Oxidative stress and mitochondrial dysfunction are hypothesized to contribute to the pathogenesis of chronic cholestatic liver diseases. Silent information regulator 1 (SIRT1) attenuates oxidative stress and improves mitochondrial biogenesis in numerous mitochondrial-related diseases; however, a functional role for SIRT1 in chronic liver cholestasis, characterized by increased levels of toxic bile acids, remains unknown. We show decrease in SIRT1 levels and its activity and impairment of mitochondrial biogenesis in the liver of patients with extrahepatic cholestasis. Moreover, we found that glycochenodeoxycholic acid (GCDCA) stimulated cytotoxicity, disrupted the mitochondrial membrane potential, increased reactive oxygen species production, and decreased mitochondrial mass and mitochondrial DNA content in L02 cells. Consistent with this finding, GCDCA was found to decrease SIRT1 protein expression and activity, thus promoting the deacetylation of peroxisome proliferator-activated receptor gamma, coactivator 1 alpha (PGC-1α), a key enzyme involved in mitochondrial biogenesis and function. Conversely, GCDCA-induced mitochondrial injury was efficiently attenuated by SIRT1 overexpression. In summary, these findings indicate that the loss of SIRT1 may play a crucial role in the pathogenesis of liver damage observed in patients with extrahepatic cholestasis. The findings also indicate that genetic supplementation of SIRT1 can ameliorate GCDCA-induced hepatotoxicity through the activation of PGC-1α-dependent mitochondrial biogenesis.

Abstract
Sonic hedgehog (Shh) functions as a conserved morphogen in the development of various organs in metazoans ranging from Drosophila to humans. Here, we have investigated the potential roles and underlying mechanisms of Shh signaling in murine placentation. Immunostaining revealed the abundant expression of the main components of Shh pathway in both the trophectoderm of blastocysts and developing placentas. Disruption of Shh led to impaired vascularogenesis of yolk sac, less branching and malformation of placental labyrinth, thereby leading to a robust decrease in capacity of transplacental passages. Moreover, placenta-specific gene incorporation by lentiviral transduction of mouse blastocysts and blastocyst transplantation robustly knocked down the expression of Gli3 and Gli2 in placenta but not in embryos. Finally, Gli3 knockdown in Shh−/− placentas partially rescued the defects of both yolk sac and placental labyrinth, and robustly restored the capacity of transplacental passages. Gli2 knockdown in Shh+/− placentas affected neither the capacity of tranplacental passages nor the vascularogenesis of yolk sac, however, it partially phenocopied the labyrinthine defects of Shh−/− placentas. Taken together, these results uncover that both Shh/Gli2 and Shh/Gli3 signals are required for proper development of murine placentas and are possibly essential for pregnant maintenance.

Abstract
Nicotinamide phosphoribosyltransferase (NAMPT) is the key enzyme in the biosynthesis of nicotinamide adenine dinucleotide (NAD). In the brain, NAMPT is primarily expressed in neurons and can prevent neuronal degeneration. NAMPT is also highly expressed in inflammatory cells, and is responsible for their activation. Since inflammation following traumatic brain injury enhances neuronal damage, we assessed the effects of nicotinamide mononucleotide (NMN), the direct NAMPT metabolite, and FK866, a potent NAMPT inhibitor, on brain injury in a cryoinjury mouse model. Twenty-four hours after brain cryoinjury, the density of neuron and the level of NAD decreased. Both NMN and FK866 alleviated the neuronal loss and decreased the lesion volume. NMN prevented the cryoinjury-induced decrease of NAD level, and FK866 decreased it further. On day 14 after cryoinjury, further neuronal loss occurred, astrocytes and Iba1-positive macrophage/microglia activated, and the NAD level increased. At this time-point, NAMPT expression was strongly induced in Iba1-positive macrophages/microglia in the lesion core. NMN and FK866 also alleviated the neuronal loss and decreased the lesion volume. In addition, FK866 significantly attenuated the activation of astrocytes and Iba1-positive macrophages/microglia, and decreased the NAD, while NMN had no such effects. Taken together, both FK866 and NMN attenuate traumatic brain injury. However, FK866 acts via the inhibition of the NAMPT activity in inflammatory cells resulting in the inhibition of inflammation, whereas NMN is effective via replenishing NAD.

Abstract
PURPOSE The poor prognosis of gastroesophageal junction (GEJ) adenocarcinoma is largely associated with metastasis. We here report the first study to investigate the expression of epithelial-mesenchymal transition (EMT) markers Snail1 and E-cadherin in GEJ adenocarcinoma. METHODS Snail1 and E-cadherin were detected by immunohistochemistry in a cohort of 128 patients with surgically resected GEJ adenocarcinoma. We assessed the pathologic and prognostic relevance in all patients and within clinically different preserved E-cadherin and reduced E-cadherin-expressing sub-groups. RESULTS Immunoreactivity for Snail1 and E-cadherin was positive in 68 and 43 % of tumors, respectively. Snail1-positive tumors had more frequent lymph node metastasis and advanced tumor stage. E-cadherin expression was highly associated with histological differentiation, tumor size, advanced stage, presence of lymph node metastasis and distant metastasis. Patients with positive E-cadherin expression or negative Snail1 expression had significantly favorable overall survival rate. In E-cadherin-preserved tumors, the expression of Snail1 was related to lymph node metastasis, advanced stage and poor patient outcome. However, Snail1 expression had no statistically significant relationship with clinicopathologic parameters or prognosis in the reduced E-cadherin-expressing sub-group. Multivariate survival analysis identified that tumor stage [hazard ratio (HR) 2.440; 95 % confidence interval (CI) 1.216-4.896; P = 0.012], lymph node metastasis (HR 2.404; 95 % CI 1.188-4.867; P = 0.015) and gender (HR 3.244; 95 % CI 1.568-6.714; P = 0.002) were independent prognostic markers for overall survival. CONCLUSIONS Snail1 may act more critically in E-cadherin-positive tumors. Evaluation of Snail1 and E-cadherin in GEJ adenocarcinoma may help in assessing malignant properties and stratifying patients.

Abstract
BACKGROUND Funnel technique is a method used for the insertion of screw into thoracic pedicle. AIM To evaluate the biomechanical characteristics of thoracic pedicle screw placement using the Funnel technique, trying to provide biomechanical basis for clinical application of this technology. METHODS 14 functional spinal units (T6 to T10) were selected from thoracic spine specimens of 14 fresh adult cadavers, and randomly divided into two groups, including Funnel technique group (n = 7) and Magerl technique group (n = 7). The displacement-stiffness and pull-out strength in all kinds of position were tested and compared. RESULTS Two fixed groups were significantly higher than that of the intact state (P < 0.05) in the spinal central axial direction, compression, anterior flexion, posterior bending, lateral bending, axial torsion, but there were no significant differences between two fixed groups (P > 0.05). The mean pull-out strength in Funnel technique group (789.09 ± 27.33) was lower than that in Magerl technique group (P < 0.05). CONCLUSIONS The Funnel technique for the insertion point of posterior bone is a safe and accurate technique for pedicle screw placement. It exhibited no effects on the stiffness of spinal column, but decreased the pull-out strength of pedicle screw. Therefore, the funnel technique in the thoracic spine affords an alternative for the standard screw placement.

Abstract
BACKGROUND Chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII, also known as NR2F2) promotes metastasis by functioning in the tumour microenvironment; however, the role of COUP-TFII in colorectal cancer remains unknown. METHODS Human colon adenocarcinoma tissues were collected to test COUP-TFII expression. Wound-healing and cell invasion assay were used to evaluate migration and invasion of cells. Chicken ovalbumin upstream promoter-transcription factor II and related protein expression was assessed by immunostaining, immunoblotting and real-time PCR assay. Tamoxifen-inducible COUP-TFII knockout mice were employed to test COUP-TFII functions on colon cancer metastasis in vivo. RESULTS Elevated expression of COUP-TFII in colorectal adenocarcinoma tissue correlated with overexpression of the Snail1 transcription factor. High COUP-TFII expression correlated with metastasis and shorter patient survival. Chicken ovalbumin upstream promoter-transcription factor II regulated the migration and invasion of cancer cells. With Snail1, COUP-TFII inhibited expression of adherence molecules such as ZO-1, E-cadherin and β-catenin in colorectal cancer cells. Overexpression of COUP-TFII was required for cancer cells to metastasise in vivo. Chicken ovalbumin upstream promoter-transcription factor II regulated the transcription and expression of Snail1 by directly targeting the Snail1 promoter and regulated associated genes. CONCLUSIONS Chicken ovalbumin upstream promoter-transcription factor II was crucial for colorectal cancer metastasis and regulated cell migration and metastasis in conjunction with Snail1. Chicken ovalbumin upstream promoter-transcription factor II was found to be a biomarker associated with patient survival and colorectal cancer metastasis.

Abstract
OBJECTIVES To describe the characteristics of patients who visited halitosis clinic and to investigate the factors that may associate with halitosis. MATERIALS AND METHODS Nine hundred and eleven patients, who visited halitosis clinic for consultations, underwent organoleptic tests and volatile sulfur compound (VSC) measurements with a portable sulfide monitor. The oral health of patients, including dental caries, oral hygiene, and gingival inflammation status, was assessed. Questionnaires were used to obtain information on demographics, oral hygiene practices, and dietary habits. RESULTS Of the 911 patients, more females than males visited the clinic. Patients' age ranged from 18 to 82 years (mean ± s.d.: 40.8 ± 14.1). Almost 30% of patients had complained of halitosis for over 5 years before looking into treatments. Approximately half of the patients self-perceived that they were unable to get close to others. Around 77% of patients had halitosis. Results of multiple logistic regressions for organoleptic scores and VSC values showed that tongue coating and tongue scraping were significantly associated with halitosis (P < 0.05). CONCLUSIONS Among these Chinese patients, over three-quarters of patients had halitosis, and negative impacts on social communications were observed. Tongue coating was the most important factor responsible for halitosis.

Abstract
We present an effective method for defocus map estimation from a single natural image. It is inspired by the observation that defocusing can significantly affect the spectrum amplitude at the object edge locations in an image. By establishing the relationship between the amount of spatially varying defocus blur and spectrum contrast at edge locations, we first estimate the blur amount at these edge locations, then a full defocus map can be obtained by propagating the blur amount at edge locations over the entire image with a nonhomogeneous optimization procedure. The proposed method takes into consideration not only the affect of light refraction but also the blur texture of an image. Experimental results demonstrate that our proposed method is more reliable in defocus map estimation compared to various state-of-the-art methods.

Abstract
OBJECTIVES Stem cells from the dental apical papilla (SCAPs) can be induced to differentiate along both osteoblast and odontoblast lineages. However, little knowledge is available concerning their differentiation efficiency in osteogenic media containing additional KH2 PO4 . MATERIALS AND METHODS Stem cells from the dental apical papilla were isolated from apical papillae of immature third molars and treated with two kinds of mineralization-inducing media, MM1 and MM2, differing in KH2 PO4 concentration. Proliferation and osteo/odontogenic differentiation capacity of MM1/MM2-treated SCAPs were investigated and compared both in vitro and in vivo. RESULTS Cell counting and flow cytometry demonstrated that MM2 containing 1.8 mm additional KH2 PO4 significantly enhanced proliferative potential of SCAPs, compared to MM1. Osteo/odontogenic capacity of SCAPs was much better in MM2 medium than in MM1, as indicated by elevated alkaline phosphatase activity, increased calcium deposition and upregulated expression of osteo/odontoblast-specific genes/proteins (for example, runt-related transcription factor 2, osterix, osteocalcin, dentin sialoprotein, and dentin sialophosphoprotein). In vivo transplantation findings proved that SCAPs in MM2 group generated more mineralized tissues, and presented higher expression of osteo/odontoblast-specific proteins (osteocalcin and dentin sialoprotein) than those in the MM1 group. CONCLUSION Mineralization-inducing media supplemented with 1.8 mm additional KH2 PO4 significantly enhanced cell proliferation and improved differentiation capacity of SCAPs along osteo/odontogenic cell lineages, compared to counterparts lacking additional KH2 PO4 .

Abstract
AIMS/HYPOTHESIS The activation of NADPH oxidase has been implicated in NEFA-induced beta cell dysfunction. However, the causal role of this activation in vivo remains unclear. Here, using rodents, we investigated whether pharmacological or genetic inhibition of NADPH oxidase could prevent NEFA-induced beta cell dysfunction in vivo. METHODS Normal rats were infused for 48 h with saline or oleate with or without the NADPH oxidase inhibitor apocynin. In addition, NADPH oxidase subunit p47(phox)-null mice and wild-type littermate controls were infused with saline or oleate for 48 h. This was followed by measurement of NADPH oxidase activity, reactive oxygen species (ROS) and superoxide imaging and assessment of beta cell function in isolated islets and hyperglycaemic clamps. RESULTS Oleate infusion in rats increased NADPH oxidase activity, consistent with increased total but not mitochondrial superoxide in islets and impaired beta cell function in isolated islets and during hyperglycaemic clamps. Co-infusion of apocynin with oleate normalised NADPH oxidase activity and total superoxide levels and prevented beta cell dysfunction. Similarly, 48 h NEFA elevation in wild-type mice increased total but not mitochondrial superoxide and impaired beta cell function in isolated islets. p47(phox)-null mice were protected against these effects when subjected to 48 h oleate infusion. Finally, oleate increased the levels of total ROS, in both models, whereas inhibition of NADPH oxidase prevented this increase, suggesting that NADPH oxidase is the main source of ROS in this model. CONCLUSIONS/INTERPRETATION These data show that NADPH-oxidase-derived cytosolic superoxide is increased in islets upon oleate infusion in vivo; and whole-body NADPH-oxidase inhibition decreases superoxide in concert with restoration of islet function.

Abstract
It has been known that the gut microbiota plays a central role in shaping normal mucosal immunity, however, little information is available whether the variability of mucosal lymphocytes impacts the commensal flora. Here, we applied a cynomolgus monkey model to characterize the structure and composition of the gut microbiota in response to lymphocyte depletion and to determine their potential association. Molecular profiling of 16S rDNA showed that the intestinal microbiota composition was perturbed after the depletion of mucosal lymphocytes and were recovered following the repopulation. Some specific bacteria from the orders Lactobacillales, Enterobacteriales and Clostridiales, and the genus Prevotella and Faecalibacterium, were primarily responsible for the variations of the gut microbiota after lymphocyte depletion. Interestingly, the species richness of the ileal mucosal microbiota was associated the proportions of TCRαβ+ or TCRγδ+ T cells (p<0.01). We demonstrate for the first time the feature of intestinal microbiota composition after lymphocyte depletion and provide novel evidence that the perturbation of gut microbiota is associated with lymphocyte depletion. It may contribute to understand the relationship between gut commensal microbiota and mucosal immune system. Study results provide insight into biological activity of alemtuzumab in intestinal barrier in organ transplantation.

Abstract
Intermedin (IMD) plays an important regulatory role in cardiovascular function. We aimed to explore the protein expression of IMD and its receptors, calcitonin receptor-like receptor (CRLR) and receptor activity-modifying proteins (RAMPs), and the role of endogenous IMD in myocardial ischemia/reperfusion (I/R) injury in rats. The rat model of I/R was created by ligating cardiac left anterior descending artery. Western blot was used to determine protein expression of CRLR and RAMPs, and radioimmunoassay was used to detect IMD content. Compared with control, protein levels of CRLR and RAMPs in both ischemic and nonischemic region were upregulated at different stages of reperfusion. IMD protein content in nonischemic area myocardium also increased. However, IMD protein content in ischemic area downregulated at 3-, 6-, and 12-h reperfusion. In hypoxia/reoxygenation model of neonatal cardiomyocytes, IMD attenuated myocyte injury, and IMD receptor antagonist IMD17-47 aggravated myocyte impairment by blocking endogenous IMD. In conclusion, the downregulation of IMD at early stage of reperfusion might augment myocardium injury.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common worldwide malignancies. A relative complete diagnosis system for primary carcinoma of liver has already been established, but the surgical prognosis for HCC, which depends mainly on postoperative pathological classification and data of recurrence and metastasis, lacks valid experimental indicators. Macrophage migration inhibition factor (MIF) is related to many cancers; hence, the polymorphism of MIF genes may be associated with the surgical prognosis of HCC. The purpose of this study was to investigate the relationship between polymorphisms of MIF gene promoter 794CATT (MIF-794CATT) microsatellite repeats and HCC surgical prognosis and evaluate the contribution of polymorphism to the prognosis of hepatectomy. Sequencing was used to identify the MIF-794CATT of 241 patients who had been submitted to HCC surgery. These patients were classified into 2 groups: one with MIF-794CATT high-repetitive-sequence genotypes (7/x+8/x) and one with low-repetitive-sequence genotypes (5/5+5/6+6/6). Five indictors were analyzed: average survival times were compared using the t-test, and tumor-node-metastasis staging, recurrence and metastasis, differentiation grade, and survival rate were compared using the chi-square test. The (7/x+8/x) CATT group had 139 patients and the (5/5+5/6+6/6) CATT group had 102. Significant differences were found in the 5 factors (P = 0.000, 0.008, 0.002, 0.000, and 0.003, respectively). Patients with MIF-794CATT5-8 low-repetitive-sequence genotypes had better prognosis than those with high-repetitive-sequence genotypes. The polymorphism detection of MIF-794CATT microsatellite repeats is valuable for HCC surgical prognosis.

Abstract
We report on investigations into the fundamental surface emission parameters, the geometric field enhancement factor (β) and the work function (φ), by making both field emission and Schottky-enabled photoemission measurements. The measurements were performed on a copper surface in the Tsinghua University S-band RF gun in two separate experiments. Fitting our data to the models for each experiment indicate that the traditionally assumed high value of β(≈50-500) does not provide a plausible explanation of the data, but incorporating a low value of φ at some sites does. In addition, direct measurements of the surface conducted after the experiment show that β is on the order of a few, consistent with our understanding of the electron emission measurements. Thus we conclude that the dominant source of electron emission in high gradient RF cavities is due to low φ sites, as opposed to the conventionally assumed high β sites. The origin of low φ at these sites is unclear and should be the subject of further investigation.

Abstract
A multilayered hydrogel film system based on hyaluronic acid-cysteamine (HA-Cym) and polyvinylalcohol (PVA) was fabricated. It contained a drug-impermeable backing layer, a supporting layer preventing direct contact between the loaded drug and the backing layer, a drug-loading layer and a mucoadhesive layer. Scanning electron microscopy demonstrated the presence of the distinct layers. The composition and preparation procedure of the films influenced their mucoadhesion, swelling, in vitro release of insulin and loaded insulin stability. Vacuum drying and crosslinked PVA with glutaraldehyde might reduce mucoadhesion, and they partially decreased the bioactivity of loaded insulin. Lyophilized hydrogel film with uncrosslinked PVA as a mucoadhesive layer possessed high mucoadhesion and showed no influence on the bioactivity of loaded insulin. The application of vacuum-dried PVA-crosslinked HA-Cym/PVA hydrogel film as a drug-impermeable backing layer would provide a controllable unidirectional insulin release. Therefore, such a multilayered hydrogel film system could be a promising mucoadhesive delivery system for controlled macromolecular drug release.

Abstract
The free energies of six crystal structures associated with Cu-Zr alloys-Cu (face centred cubic), Cu(2)Zr, Cu(10)Zr(7), CuZr, CuZr(2) and Zr (hexagonal close packed)-are calculated using the embedded atom potential of Mendelev et al (2009 Phil. Mag. 89 967). We find that the observed low temperature stability of the Cu(10)Zr(7) and CuZr(2) phases is not reproduced. Instead, the model predicts that the CuZr phase remains stable down to T = 0 K. This discrepancy is largely removed when the interaction potentials are cut off at a short distance, such as that used by Duan et al (2005 Phys. Rev. B 71 224208). We present evidence, however, that the cut-off distance necessary to achieve the change in phase stability results in pathological artefacts in the energetics of some crystal phases.

Abstract
AIMS/HYPOTHESIS Rapamycin impairs glucose tolerance and insulin sensitivity. Our previous study demonstrated that rapamycin significantly increases the production of gastric ghrelin, which is critical in the regulation of glucose metabolism. Here, we investigated whether ghrelin contributes to derangements of glucose metabolism induced by rapamycin. METHODS The effects of rapamycin on glucose metabolism were examined in mice receiving ghrelin receptor antagonist or with Ghsr1a gene knockout. Changes in GLUT4, c-Jun N-terminal kinase (JNK) and phosphorylated ribosomal protein S6 (pS6) were investigated by immunofluorescent staining or western blotting. Related hormones were detected by radioimmunoassay kits. RESULTS Rapamycin impaired glucose metabolism and insulin sensitivity not only in normal C57BL/6J mice but also in both obese mice induced by a high fat diet and db/db mice. This was accompanied by elevation of plasma acylated ghrelin. Rapamycin significantly increased the levels of plasma acylated ghrelin in normal C57BL/6J mice, high-fat-diet-induced obese mice and db/db mice. Elevation in plasma acylated ghrelin and derangements of glucose metabolism upon administration of rapamycin were significantly correlated. The deterioration in glucose homeostasis induced by rapamycin was blocked by D: -Lys3-GHRP-6, a ghrelin receptor antagonist, or by deletion of the Ghsr1a gene. Ghrelin receptor antagonism and Ghsr1a knockout blocked the upregulation of JNK activity and downregulation of GLUT4 levels and translocation in the gastrocnemius muscle induced by rapamycin. CONCLUSIONS/INTERPRETATION The current study demonstrates that ghrelin contributes to derangements of glucose metabolism induced by rapamycin via altering the content and translocation of GLUT4 in muscles.

Abstract
BACKGROUND In Western countries, a history of major depression (MD) is associated with reports of received parenting that is low in warmth and caring and high in control and authoritarianism. Does a similar pattern exist in women in China? METHOD Received parenting was assessed by a shortened version of the Parental Bonding Instrument (PBI) in two groups of Han Chinese women: 1970 clinically ascertained cases with recurrent MD and 2597 matched controls. MD was assessed at personal interview. RESULTS Factor analysis of the PBI revealed three factors for both mothers and fathers: warmth, protectiveness, and authoritarianism. Lower warmth and protectiveness and higher authoritarianism from both mother and father were significantly associated with risk for recurrent MD. Parental warmth was positively correlated with parental protectiveness and negatively correlated with parental authoritarianism. When examined together, paternal warmth was more strongly associated with lowered risk for MD than maternal warmth. Furthermore, paternal protectiveness was negatively and maternal protectiveness positively associated with risk for MD. CONCLUSIONS Although the structure of received parenting is very similar in China and Western countries, the association with MD is not. High parental protectiveness is generally pathogenic in Western countries but protective in China, especially when received from the father. Our results suggest that cultural factors impact on patterns of parenting and their association with MD.
