Abstract
Background and study aims Carbohydrate antigen 19-9 (CA199) has been identified as a tumor marker for pancreatic cancer but also increases in benign lesions of the digestive system. However, literature associated with the relationship between CA199 and acute pancreatitis (AP) is limited. This study aimed to focus on serum CA199 level measurements in AP patients and the associated clinical significance. Materials and methods From January 2006 to December 2015, 1,609 consecutive patients with AP were admitted to our department and included in the study. The relationships among the etiology of AP, the disease severity, the incidence of pancreatic cancer during hospitalization and CA199 levels were analyzed. Results Serum CA199 levels were measured for 693 of 1,609 AP patients. Of those patients, 186 (26.8%) had elevated CA199 levels (> 37 U/ml). Patients with high CA199 levels were older and had predominantly biliary causes in comparison with patients with normal CA199 levels. There were no definite specific correlations between CA199 levels and disease severity in AP. In addition, serum levels of CA199 positively correlated with serum alanine aminotransferase, aspartate transaminase, glutamyl transpeptidase, alkaline phosphatase and creatinine levels. After stratification, the incidence of pancreatic cancer increased proportionally to CA199 levels in AP patients. Conclusions Serum CA199 levels was elevated in patients with AP, especially in patients with biliary pancreatitis. AP patients with significantly increased CA199 levels may have a higher risk for the presence of pancreatic cancer. We recommended routinely monitoring CA199 levels during hospitalization for AP patients.

Abstract
OBJECTIVE Hand, foot and mouth disease (HFMD) is mainly caused by enterovirus 71 (EV71) or coxsackie virus A16 infection. Severe HFMD with encephalitis is a life-threatening disease for children. This study aimed to examine the levels of a variety of inflammatory cytokines in HFMD patients. METHODS Sera of severe or common HFMD patients and cerebrospinal fluids from severe HFMD patients in the acute or recovery phase were collected to analyse 40 cytokines using the Raybiotec Cytokine array. Twenty-six samples of sera or cerebrospinal fluids from HFMD patients were further detected using Milliplex beads. RESULTS Numerous inflammatory cytokines, such as IL-8, IP-10, and RAENTES, were enhanced in the sera and cerebrospinal fluids of encephalitis-complicated HFMD patients. Serum IL-12p40 and IL-15 levels were higher in severe HFMD patients compared with common patients. Moreover, IL-8 and IP-10 levels in the cerebrospinal fluid were sharply enhanced by 30-fold on average compared with those in the sera. Cerebrospinal fluid IL-8, IP-10, and RANTES levels were significantly enhanced in the acute phase of severe HFMD patients compared with those in the recovery phase. However, no correlation of serum IL-8 or IP-10 level with its cerebrospinal fluid level was observed. CONCLUSION An inflammatory cytokine storm occurs both in sera and cerebrospinal fluids during severe HFMD, which is likely a Th1 cell-associated disease. Cerebrospinal fluid IL-8, IP-10 and RANTES levels could be used as potential biomarkers for diagnosing severe HFMD, whereas the enhanced serum levels of IL-12p40 and IL-15 could be used as candidate predictive factors for severe HFMD.

Abstract
Porcine postweaning multisystemic wasting syndrome (PMWS) caused by porcine circovirus type 2 (PCV2) is a disease causing severe economic losses annually worldwide to the pig industry. PCV2 infection was first reported in China in 2000, and currently has three major genotypes, PCV2a, b and d, circulating in this country. To further elucidate the origin and prevalence of PCV2 in China, 123 clinical pig tissue samples collected in 25 provinces between 1990 and 1999 were analysed by PCV2-specific PCR, resulting in identification of 23 PCV2 strains collected between 1996 and 1999. Phylogenetic analysis based on the nucleotide sequences of open reading frame 2 (ORF2) showed that 20 of the 23 grouped within PCV2a, while the remaining three strains formed an independent clade, so far unreported and therefore named PCV2f. This genotype shared lower sequence identity with other known genotypes. This study provides further understanding of the genetic diversity and evolution of PCV2 and has tracked PCV2 infection in China back to 1996 rather than 2000.

Abstract
Toll‑like receptors (TLRs) serve a vital role in activating the innate immune system by sensing conserved microbial products. Fc γ receptor IIb (FcγRIIb), the inhibitory Fc receptor, exerts its immune regulatory functions by binding to the immunoglobulin G Fc domain. Although the individual roles of TLRs and FcγRIIb have been studied intensively, the cross‑talk between FcγRIIb and TLR4 on B cells remains unknown. The present study demonstrated that FcγRIIb ligation by the immune complex (IC) attenuated the TLR4‑triggered nuclear factor (NF)‑κΒ activation, and decreased the release of interleukin (IL)‑6 from B cells, via enhancing LYN proto‑oncogene (Lyn) phosphorylation. In addition, IC treatment protected mice from lethal endotoxic shock. Accordingly, IC decreased the LPS‑induced serum levels of IL‑6, as well as intracellular IL‑6 production in B cells in vivo. However, these protective and inhibitory effects of IC were not observed in FcγRIIb‑/‑ mice. In conclusion, the present data demonstrated that FcγRIIb inhibited TLR4 signaling in B cells by activating Lyn phosphorylation and by inhibiting NF‑κΒ signaling. The present study elucidated the mechanism associated with the TLR4 and FcγRIIb cross‑talk in B cells.

Abstract
Nanoparticles can be loaded with exogenous DNA for the potential expression of cytokines with immune-stimulatory function. NKG2D identifies major histocompatibility complex class I chain-related protein in human and retinoic acid early induced transcript-1 in mouse, which acts as tumor-associated antigens. Biologic agents based on interleukin 21 (IL-21) have displayed antitumor activities through lymphocyte activation. The NKG2D-IL-21 fusion protein theoretically identifies tumor cells through NKG2D moiety and activates T cells through IL-21 moiety. In this study, double-gene fragments that encode the extracellular domains of NKG2D and IL-21 genes were connected and then inserted into the pcDNA3.1(-) plasmid. PcDNA3.1-dsNKG2D-IL-21 plasmid nanoparticles based on chitosan were generated. Tumor cells pretransfected with dsNKG2D-IL-21 gene nanoparticles can activate natural killer (NK) and CD8+ T cells in vitro. Serum IL-21 levels were enhanced in mice intramuscularly injected with the gene nanoparticles. DsNKG2D-IL-21 gene nanoparticles accumulated in tumor tissues after being intravenously injected for ~4-24 h. Treatment of dsNKG2D-IL-21 gene nanoparticles also retarded tumor growth and elongated the life span of tumor-bearing mice by activating NK and T cells in vivo. Thus, the dsNKG2D-IL-21 gene nanoparticles exerted efficient antitumor activities and would be potentially used for tumor therapy.

Abstract
Expression of surface NKG2D ligands on tumour cells, which activates nature killer (NK) cells and CD8+ T cells, is crucial in antitumour immunity. Some types of tumours have evolved mechanisms to suppress NKG2D‐mediated immune cell activation, such as tumour‐derived soluble NKG2D ligands or sustained NKG2D ligands produced by tumours down‐regulate the expression of NKG2D on NK cells and CD8+ T cells. Here, we report that surface NKG2D ligand RAE1ε on tumour cells induces CD11b+Gr‐1+ myeloid‐derived suppressor cell (MDSC) via NKG2D in vitro and in vivo. MDSCs induced by RAE1ε display a robust induction of IL‐10 and arginase, and these MDSCs show greater suppressive activity by inhibiting antigen‐non‐specific CD8+ T‐cell proliferation. Consistently, upon adoptive transfer, MDSCs induced by RAE1ε significantly promote CT26 tumour growth in IL‐10‐ and arginase‐dependent manners. RAE1ε moves cytokine balance towards Th2 but not Th1 in vivo. Furthermore, RAE1ε enhances inhibitory function of CT26‐derived MDSCs and promotes IL‐4 rather than IFN‐γ production from CT26‐derived MDSCs through NKG2D in vitro. Our study has demonstrated a novel mechanism for NKG2D ligand+ tumour cells escaping from immunosurveillance by facilitating the proliferation and the inhibitory function of MDSCs.

Abstract
CD4+NKG2D+ T cells are associated with tumour, infection and autoimmune diseases. Some CD4+NKG2D+ T cells secrete IFN‐γ and TNF‐α to promote inflammation, but others produce TGF‐β and FasL to facilitate tumour evasion. Here, murine CD4+NKG2D+ T cells were further classified into NK1.1−CD4+NKG2D+ and NK1.1+CD4+NKG2D+ subpopulations. The frequency of NK1.1−CD4+NKG2D+ cells decreased in inflamed colons, whereas more NK1.1+CD4+NKG2D+ cells infiltrated into colons of mice with DSS‐induced colitis. NK1.1−CD4+NKG2D+ cells expressed TGF‐β and FasL without secreting IFN‐γ, IL‐21 and IL‐17 and displayed no cytotoxicity. The adoptive transfer of NK1.1−CD4+NKG2D+ cells suppressed DSS‐induced colitis largely dependent on TGF‐β. NK1.1−CD4+NKG2D+ cells did not expressed Foxp3, CD223 (LAG‐3) and GITR. The subpopulation was distinct from NK1.1+CD4+NKG2D+ cells in terms of surface markers and RNA transcription. NK1.1−CD4+NKG2D+ cells also differed from Th2 or Th17 cells because the former did not express GATA‐3 and ROR‐γt. Thus, NK1.1−CD4+NKG2D+ cells exhibited immune regulatory functions, and this T cell subset could be developed to suppress inflammation in clinics.

Abstract
With advances in natural orifice transluminal endoscopic surgery, peroral endoscopic myotomy (POEM) has become a novel treatment for esophageal achalasia. In this study, we investigated the feasibility and safety of POEM in patients with achalasia after failed endoscopic interventions. Data on all patients undergoing POEM treatment of achalasia were collected prospectively. We enrolled 61 patients who underwent POEM for achalasia between July 2011 and January 2014. The preoperative intervention group included patients who had undergone botulinum toxin injection or pneumatic balloon dilation before POEM. The preoperative, operative, and short-term outcome data between the groups were compared. Among preoperative intervention group, 22 patients received endoscopic therapy before being referred for operation (18 dilation only, 2 botulinum toxin only, and 2 both treatments). Procedure time in the preoperative intervention group was similar to the nonpreoperative intervention group (60.8 ± 30.9 vs. 62.0 ± 21.0 minutes, P = 0.863). Both groups demonstrated significant improvement in Eckardt scores and manometric outcomes at 1-year follow-up. There were no significant differences in pretreatment and posttreatment D-values of symptom scores and lower esophageal sphincter pressures between groups (6.2 ± 2.2 vs. 6.1 ± 1.8, P = 0.840; 27.9 ± 17.6 vs. 24.9 ± 15.2; P = 0.569). There was also no significant difference in the incidence of intraoperative complications (P = 0.958) and gastroesophageal reflux rate (23.5% vs. 20.0%, P = 0.771) between the two groups. Our study demonstrated that POEM is safe and effective, even for treating achalasia in the setting of failed endoscopic interventions.

Abstract
PURPOSE Fetal immature mediastinal teratoma is a rare disease. The pressure generated by the tumor mass can cause hydrops fetalis, pulmonary hypoplasia, pleural and peritoneal effusion, and polyhydramnios which cause the death of the fetus. Routine prenatal ultrasound has enabled accurate diagnosis. MATERIALS AND METHODS The authors report a 26-year-old patient, gravida 4 para 1, who was referred to this hospital, carrying a fetus with immature mediastinal teratoma. RESULTS At 27 weeks of gestation, a routine prenatal ultrasound suggested the fetus had a mass at the anterior mediastinum, accompanied by pulmonary hypoplasia, pleural and peritoneal effusion, subcutaneous edema of head and chest, and polyhydramnios. After the therapeutic abortion, the gross anatomy confirmed the mediastinal mass. The histological examination showed that the mass was a grade 2 immature teratoma. CONCLUSIONS The mother of the fetus had been exposed to plaster, paint, and paint-thinner in the first trimester of pregnancy, suggesting that these chemical contacts may be one of the causes of the disorder.

Abstract
Wogonin exerts anti‐tumour activities via multiple mechanisms. We have identified that high‐dose wogonin (50 or 100 mg/kg) could inhibit the growth of transplanted tumours by directly inducing tumour apoptosis and promoting DC, T and NK cell recruitment into tumour tissues to enhance immune surveillance. However, wogonin (20–50 μM) ex vivo prevents inflammation by inhibiting NF‐κB and Erk signalling of macrophages and epithelial cells. It is elusive whether high‐dose wogonin promotes or prevents inflammation. To investigate the effects of high‐dose wogonin on murine colitis induced by dextran sodium sulphate (DSS), mice were co‐treated with DSS and various doses of wogonin. Intraperitoneal administration of wogonin (100 mg/kg) exacerbated DSS‐induced murine colitis. More CD4+CD44+ and CD8+CD44+ cells were located in the inflamed colons in the wogonin (100 mg/kg) treatment group than in the other groups. Frequencies of CD4+CD25+CD127− and CD4+CD25+ Foxp3+ cells in the colons and spleen respectively, were reduced by wogonin treatment. Ex vivo stimulations with high‐dose wogonin (50–100 μg/ml equivalent to 176–352 μM) could synergize with IL‐2 to promote the functions of CD4+ and CD8+ cells. However, regulatory T cell induction was inhibited. Wogonin stimulated the activation of NF‐κB and Erk but down‐regulated STAT3 phosphorylation in the CD4+ T cells. Wogonin down‐regulated Erk and STAT3‐Y705 phosphorylation in the regulatory T cells but promoted NF‐κB and STAT3‐S727 activation. Our study demonstrated that high‐dose wogonin treatments would enhance immune activity by stimulating the effector T cells and by down‐regulating regulatory T cells.

Abstract
Background/Aims The functional variant (rs56109847) in the 3′-untranslated regions (3′-UTR) of the serotonin receptor 3E (HTR3E) gene is associated with female diarrhea predominant irritable bowel syndrome (IBS-D) in British populations. However, the relationship of the polymorphism both to HTR3E expression in the intestine and to the occurrence of Chinese functional gastrointestinal disorders has yet to be examined. Methods Polymerase chain reaction amplification and restriction fragment length polymorphism analyses were employed to detect polymorphisms among Chinese Han women, particularly 107 patients with IBS-D, 99 patients with functional dyspepsia (FD), 115 patients with mixed IBS and 69 patients with IBS-D + FD. We also assessed microRNA-510 (miR-510) and HTR3E expression in human colonic mucosal tissues with immunohistochemistry and other methods. Dual-luciferase reporter assays were conducted to examine the binding ability of miR-510 and HTR3E 3′-UTR. Results Genotyping data showed the variant rs56109847 was significantly associated with IBS-D, but not with FD, mixed-IBS, or FD + IBS-D. HTR3E was abundantly expressed around the colonic mucosal glands but less expressed in the stroma. miR-510 expression decreased, whereas HTR3E expression increased in the colonic mucosal tissue of patients with IBS-D compared with those in controls. HTR3E expression was significantly higher in patients with the GA genotype than that in patients with the GG genotype. The single-nucleotide polymorphisms disrupted the binding site of miR-510 and significantly upregulated luciferase expression in HEK293 and HT-29 cells. Conclusions The single-nucleotide polymorphisms rs56109847 led to reduced microRNA binding and overexpression of the target gene in intestinal cells, thereby increasing IBS-D risk in the Chinese Han population. The decreased expression of miR-510 might contribute to IBS-D.

Abstract
Because inappropriate activation of Toll-like receptor 9 (TLR9) may induce pathological damage, negative regulation of the TLR9-triggered immune response has attracted considerable attention. Nonpathogenic immune complex (IC) has been demonstrated to have beneficial therapeutic effects in some kinds of autoimmune diseases. However, the role of IC in the regulation of TLR9-triggered immune responses and the underlying mechanisms remain unclear. In this study, it was demonstrated that IC stimulation of B cells not only suppresses CpG-oligodeoxynucleotide (CpG-ODN)-induced pro-inflammatory IL-6 and IgM κ production, but also attenuates CD40 and CD80 expression. Furthermore, our results suggest that the receptor for the Fc portion of IgG (FcγR) IIb is involved in the suppressive effect of IC on TLR9-mediated CD40, CD80 and IL-6 expression. Finally, it was found that IC down-regulates TLR9 expression in CpG-ODN activated B cells. Our results provide an outline of a new pathway for the negative regulation of TLR9-triggered immune responses in B cells via FcγRIIb. A new mechanistic explanation of the therapeutic effect of nonpathogenic IC on inflammatory and autoimmune diseases is also provided.

Abstract
Infection in male and female genital tracts can lead to infertility. The underlying mechanisms of this process remain unclear. Toll-like receptors (TLRs) recognize conserved structures and respond to pathogens by initiating signals that activate inflammatory gene transcription. Here, we demonstrate that TLR activation in sperm reduces sperm motility via signalling through myeloid differentiation factor 88 (MyD88), phosphatidylinositol 3-kinase (PI3K), and glycogen synthase kinase (GSK)-3α. Upon TLR activation, phosphorylated forms of PI3K and GSK3α were detected in the mitochondria, and the mitochondrial membrane potential was impaired in sperm. In addition, mitochondrial ATP levels were decreased after TLR agonist stimulation. Furthermore, blocking PI3K or GSK3α activation abrogated these effects and reversed the TLR-induced reduction in sperm motility. These results identify a previously unrecognized TLR signalling pathway that leads to dysfunctional sperm mitochondria, which reduce sperm motility. Our study reveals a novel mechanism by which pathogenic infection affects sperm motility and possibly leads to infertility.

Abstract
A novel system to cultivate and record brain slices directly on high-density microelectrode arrays (HD-MEA) was developed. This system allows to continuously record electrical activity of selected individual neurons at high spatial resolution, while monitoring neuronal network activity at the same time. For the first time, properties of single neurons and the corresponding neuronal network in an organotypic hippocampal slice culture were studied over four consecutive weeks at daily intervals.

Abstract
Lineage (CD3e, CD11b, GR1, B220 and Ly-76) negative hematopoietic stem cells (HSCs) and hematopoietic progenitor cells (HPCs) infiltrate islet allografts within 24 h posttransplantation. In fact, lineage(negative) Sca-1(+) cKit(+) ("LSK") cells, a classic signature for HSCs, were also detected among these graft infiltrating cells. Lineage negative graft infiltrating cells are functionally multi-potential as determined by a standard competitive bone marrow transplant (BMT) assay. By 3 months post-BMT, both CD45.1 congenic, lineage negative HSCs/HPCs and classic "LSK" HSCs purified from islet allograft infiltrating cells, differentiate and repopulate multiple mature blood cell phenotypes in peripheral blood, lymph nodes, spleen, bone marrow and thymus of CD45.2 hosts. Interestingly, "LSK" HSCs also rapidly infiltrate syngeneic islet transplants as well as allogeneic cardiac transplants and sham surgery sites. It seems likely that an inflammatory response, not an adaptive immune response to allo-antigen, is responsible for the rapid infiltration of islet and cardiac transplants by biologically active HSCs/HPCs. The pattern of hematopoietic differentiation obtained from graft infiltrating HSCs/HPCs, cells that are recovered from inflammatory sites, as noted in the competitive BMT assay, is not precisely the same as that of intramedullary HSCs. This does not refute the obvious multi-lineage potential of graft infiltrating HSCs/HPCs.

Abstract
Two kinds of optical heterodyne saturation spectroscopies, namely, frequency modulation spectroscopy (FMS) and modulation transfer spectroscopy (MTS), are demonstrated for locking a fiber laser to the transition lines of metastable (4)He atoms around 1083 nm. The servo-loop error signals of FMS and MTS for stabilizing laser frequency are optimized by studying the dependence of the peak-to-peak amplitude and slope on the optical power of pump and probe beams. A comparison of the stabilization performances of FMS/MTS and polarization spectroscopy (PS) is presented, which shows that MTS exhibits relatively superior performance with the least laser frequency fluctuation due to its flat-background dispersive signal, originated from the four-wave mixing process. The Allan deviation of the stabilized laser frequency is 5.4 × 10(-12)@100 s with MTS for data acquired in 1000 s, which is sufficiently applicable for fields like laser cooling, optical pumping, and optical magnetometry.

Abstract
The binding of NKG2D to its ligands strengthens the cross-talk between natural killer (NK) cells and dendritic cells, particularly at early stages, before the initiation of the adaptive immune response. We found that retinoic acid early transcript-1ε (RAE-1ε), one of the ligands of NKG2D, was persistently expressed on antigen-presenting cells in a transgenic mouse model (pCD86-RAE-1ε). By contrast, NKG2D expression on NK cells, NKG2D-dependent cytotoxicity and tumour rejection, and dextran sodium sulphate-induced colitis were all down-regulated in this mouse model. The down-regulation of NKG2D on NK cells was reversed by stimulation with poly (I:C). The ectopic expression of RAE-1ε on dendritic cells maintained NKG2D expression levels and stimulated the activity of NK cells ex vivo, but the higher frequency of CD4(+) NKG2D(+) T cells in transgenic mice led to the down-regulation of NKG2D on NK cells in vivo. Hence, high levels of RAE-1ε expression on antigen-presenting cells would be expected to induce the down-regulation of NK cell activation by a regulatory T-cell subset.

Abstract
OBJECTIVES Liver transplantation in a mouse model is a valuable tool for studying transplantation immunobiology and clinic-relevant issues. However, the successful establishment is highly technical and demanding, impeding its widespread use. Herein, the aims of this study were to review and analyze the various techniques of liver transplantation in mice to circumvent pitfalls and minimize the incidence of complications. MATERIALS AND METHODS A search of PubMed was made by using the key words "mouse liver transplantation" for articles published between January 1973 and July 2012. Of the 473 publications identified, 14 were shown to be closely associated with mouse liver transplantation and 4 articles discussed specific microsurgical techniques. Through reviewing these articles, a series of potential factors were collected and analyzed in combination with other murine transplantation models, which might influence successfully establishing a mouse model for liver transplantation. RESULTS A mouse liver transplantation model is feasible and practical for experimental studies. Mouse strain, type of anesthesia, type of perfusion and storage solution, and reconstruction of bile duct are relevant factors but not determinants for a successful transplantation. Cold and warm ischemia time should be less than 4.0 hours and 20 minutes, respectively. CONCLUSIONS The cuff preparation, reconstruction of the hepatic artery, and length of the anhepatic phase play critical roles in successfully establishing a liver transplantation model in mice.

Abstract
Astilbin, a major bioactive compound from Rhizoma smilacis glabrae, has been reported to possess anti-inflammatory properties. Our study first evaluated astilbin on dextran sulfate sodium (DSS)-induced acute colitis in mice. By intraperitoneal injection of astilbin, the severity of colitis was attenuated, and the serum levels of IL-10 and TGF-β were increased. Using flow cytometry, a higher number of IL-10(+) dendritic cells (DCs) and TGF-β(+) DCs and a lower number of CD86(+) DCs, IL-12 p40(+) DCs, and IL-1β(+) DCs were detected in the spleen of mice with colitis after astilbin treatment. The administration of astilbin also resulted in the upregulation of CD103(+) expression in colonic DCs. In a coculture system, murine bone marrow-derived DCs pretreated with astilbin resulted in an enhanced production of CD4(+)CD25(+)Foxp3(+) T cells. The results of this study show that astilbin could be a candidate drug for inflammatory bowel disease by mediating the regulatory functions of DCs.

Abstract
[1] Atmospheric phase delays are considered to be one of the main performance limitations for high-quality satellite radar techniques, especially when applied to ground deformation monitoring. Numerical weather prediction (NWP) models are widely seen as a promising tool for the mitigation of atmospheric delays as they can provide knowledge of the atmospheric conditions at the time of Synthetic Aperture Radar data acquisition. However, a thorough statistical analysis of the performance of using NWP production in radar signal correction is missing to date. This study provides a quantitative analysis of the accuracy in using operational NWP products for signal delay correction in satellite radar geodetic remote sensing. The study focuses on the temperate, subarctic, and Arctic climate regions due to a prevalence of relevant geophysical signals in these areas. In this study, the operational High Resolution Rapid Refresh over the Alaska region (HRRR-AK) model is used and evaluated. Five test sites were selected over Alaska (AK), USA, covering a wide range of climatic regimes that are commonly encountered in high-latitude regions. The performance of the HRRR-AK NWP model for correcting absolute atmospheric range delays of radar signals is assessed by comparing to radiosonde observations. The average estimation accuracy for the one-way zenith total atmospheric delay from 24 h simulations was calculated to be better than ∼14 mm. This suggests that the HRRR-AK operational products are a good data source for spaceborne geodetic radar observations atmospheric delay correction, if the geophysical signal to be observed is larger than 20 mm.

Abstract
BACKGROUND AND AIMS Low high-density lipoprotein cholesterol (HDL-c) is a risk factor for cardiovascular disease. Brachial-ankle pulse wave velocity (baPWV) is an indicator of arterial stiffness, which is recognized as a predictor of cardiovascular disease. The aim of this study was to investigate the association between HDL-c and baPWV among middle-aged and elderly Chinese. METHODS A total number of 1133 Chinese (430 men, 703 women) aged from 50 to 90 years old were recruited from Shanghai downtown district. The baPWV and major cardiovascular risk factors of the participants were measured. RESULTS Serum HDL-c was negatively correlated with baPWV (r = -0.143, P < 0.001) after adjustment for age and gender. Multivariate linear regression analysis demonstrated that age (P < 0.001), systolic blood pressure (P < 0.001), HDL-c (P < 0.001), smoking (P = 0.001), BMI (P = 0.002), fasting plasma glucose (P = 0.004), and white blood cell (P = 0.005) were independently associated with baPWV. After multiple adjustments, participants in the highest quartile of HDL-c had an odds ratio of 0.442 (95% CI 0.268-0.729) for developing high arterial stiffness compared with participants in the lowest quartile. The association remained significant after further adjustment for major cardiovascular risk factors. CONCLUSION HDL-c has an independent protective effect on arterial stiffness in middle-aged and elderly Chinese. Early detection of HDL-c level is important in high risk populations with arterial stiffness. Increasing HDL-c level may be an attractive therapeutic target for the prevention of arterial function and subsequent disease.

Abstract
OBJECTIVE To investigate serum and sputum cytokine profiles in asthma and chronic obstructive pulmonary disorder (COPD). METHODS Clinical characteristics, blood and sputum samples were collected from asthma (n = 37) and COPD (n = 36) patients, and healthy subjects (n = 39). Cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and inflammation antibody array; levels were analysed according to smoking status and presence of eosinophilia in the airways of COPD/asthma patients, and compared with those in healthy subjects. RESULTS ELISA revealed a significant difference in the expression of only a few cytokines in the COPD versus asthma groups, and in both patient groups compared with healthy subjects. The antibody array showed greater differentiation in inflammatory mediators. In the subphenotype analysis, the differential expression of cytokines was more significant between eosinophilic and noneosinophilic airway inflammation than between asthma and COPD, according to both the ELISA and antibody array. There was little difference in cytokine expression between smoking and nonsmoking subgroups. CONCLUSIONS Differential expression of inflammatory mediators is present between patients with COPD or asthma, and eosinophilic or noneosinophilic airway inflammation, and contributes to understanding the cytokine network of airway inflammation.

Abstract
Liver X receptors (LXRs), including LXRα and LXRβ isoforms, have important roles in the metabolic regulation of glucose, cholesterol and lipid. Moreover, activation of LXRs also represses the expression of cyclin D1 and cyclin B1, and thus suppresses the proliferation of multiple cancer cells, but the relevant mechanism is not well known. Forkhead box M1 (FOXM1) is a proliferation-specific member of forkhead box family, which is highly expressed in proliferating normal cells and numerous cancer cells. FOXM1 directly activates transcription of cyclin D1 and cyclin B1, resulting in the enhancement of cell cycle progression and cell proliferation. However, it is unclear whether LXRs are involved in the regulation of FOXM1. In this study, we demonstrated that specific LXRs agonists downregulated expression of FOXM1, cyclin D1 and cyclin B1 in hepatocellular carcinoma (HCC) cells, which led to cell cycle and cell proliferation arrest. Knockdown of FOXM1 significantly alleviated LXRs activation-mediated cell cycle arrest and cell growth suppression. Reporter assays showed that the activation of LXRs significantly reduced the transcriptional activity of FOXM1 promoter. Electrophoretic mobility shift assay and chromatin immunoprecipitation assays demonstrated that LXRα but not LXRβ could bind to an inverted repeat IR2 (-52CCGTCAcgTGACCT-39) in the promoter region of FOXM1 gene. Moreover, the xenograft tumor growth and the corresponding FOXM1 expression in nude mice were dramatically repressed by LXRs agonists. Taken together, we conclude that LXRα but not LXRβ functions as a transcriptional repressor for FOXM1 expression. The pathway 'LXRα-FOXM1-cyclin D1/cyclin B1' is a novel mechanism by which LXRs suppress the proliferation of HCC cells, suggesting that the pathway may be a novel target for HCC treatment.

Abstract
BACKGROUND Poor early graft function (EGF), a frequent complication of kidney transplantation, can be caused by many risk factors, including donor kidney and body weights. METHODS We studied the relationship to early graft function in a rat kidney transplantation model among 3 indices: ratio of graft to body weight; ratio of native kidney to body weight, and weight difference/body weight of the recipient. We categorized 2 groups based on contralateral nephrectomy at day 1 (G1) or day 3 (G2) after transplantation. EGF was evaluated by measuring serum creatinine levels at day 1 after bilateral nephrectomy. RESULTS The 3 indices, ie, weight difference/body weight of recipient (G1 and G2: P < .0001), ratio of native kidney to body weight (G1: P < .0001; G2: P = .0013), and ratio of graft to body weight (G1: P = .0064; G2: P = .014) strongly correlated with EGF regardless of the time of contralateral nephrectomy. CONCLUSIONS The index of weight difference/body weight of recipient sensitively and predominantly influenced EGF, which probably reflects the systemic metabolic profile.

The microcellular foamed polypropylene (PP)/mica composites were prepared through chemical microcellular injection to investigate the relationship between the mechanical behavior and the cell size. The mechanical behavior model of the microcellular foams is built based on the elastic stress/strain field. The mechanical behavior of the microcellular composites coincides well with the theoretical model. Under loading the large and non uniform cells are in a state of plane strain, which leads to low tensile and impact strengths, whereas small and uniform cells are in a state of plane stress, which contributes to the transition from brittle to tough fracture behavior in the microcellular PP/mica composite.

Abstract
Abstract
Microcellular foamed polypropylene (PP)/SiO2 composites were prepared by using micro-SiO2 and nano-SiO2 particles. The effects of the particle size of SiO2 on the foaming behavior and mechanical properties of the composites were studied based on heterogeneous nucleation theory. The results showed that the silica facilitated the cell nucleation to some extent. The average cell size of 16.3 μm and the cell density of 4.46 × 107 cells/cm3 were achieved for the composite foam at the silica content of 4 wt.%. The plastic deformation of the PP was strongly constrained due to the presence of the nano-silica. The tensile and impact strength of the nano-SiO2 composite foam are larger than those of the micro-SiO2 composite foam due to the high crack propagation resistance in the microcellular PP/nano-SiO2 composite.

Abstract
PURPOSE To evaluate the therapeutic results of superselective uterine artery infusion and embolization in 40 patients with fallopian tube ectopic pregnancy, and to explore the role of this minimally invasive treatment as an alternative to surgery. MATERIALS AND METHODS Superselective catheterization of uterine artery through cannulation of femoral artery was achieved in 40 patients with fallopian tube ectopic pregnancy (EP). Location of the lesions involved feeding arteries and active bleeding were observed through angiography. Methotrexate (MTX) diluted in saline water was slowly infused into the target artery. Small gelatin spongy particles were used to embolize the uterine artery until its branches were totally obliterated. Follow-up was undertaken to observe the results of the treatment. RESULTS Superselective uterine arterial infusion and embolization were successfully performed in all 40 patients without any related complications. Active bleeding in the peritoneum in 33 cases ceased soon after embolization. The embryos in 13 patients were confirmed to have died by ultrasound three days after the procedure. Beta-human chorionic gonadotropin ((beta-hCG) value dropped to below 15 IU/L at three to 21 days. Hemorrhage in the peritoneum dissolved after seven days in all cases. Mixed mass disappeared after one month. Hysterosalpingography was performed three months after the procedure in 19 patients and patent fallopians were demonstrated in 16 patients. CONCLUSIONS Superselective uterine arterial infusion and emboliztion is a minimally invasive procedure, which can be used to effectively treat EP by disabling the ectopic embryo and leaking arteries with the advantages of preserving the fallopian tubes.

Abstract
BACKGROUND AND STUDY AIM Although the majority of submucosal tumors (SMTs) are benign, some do have a malignant potential. Resection of SMTs would aid in establishing the diagnosis and may be curative. Our aim was to examine the feasibility and safety of a novel method for endoscopic resection of upper gastrointestinal SMTs. PATIENTS AND METHODS In 12 patients who presented with an upper gastrointestinal SMT of ≤40 mm located in the esophagus or cardia, a submucosal tunnel was endoscopically created starting approximately 5 cm proximal to the lesion. After careful submucosal dissection with carbon dioxide or air insufflation, the SMTs were completely removed, and the entrance of the tunnel closed using endoclips. RESULTS SMTs had a mean size of 19.5 mm (range 10-40 mm); eight were located in the esophagus and four in the cardia. SMT resection was successful in all patients with en bloc resection in 10 patients (83.3%) and resection in two pieces in the remaining two patients. The mean time required for the procedure was 48.3 minutes (range 30-60 minutes). Two patients had both pneumothorax and subcutaneous emphysema. All the complications resolved with conservative management. CONCLUSIONS In this pilot study, endoscopic submucosal tunnel dissection (ESTD) of esophageal and cardia SMTs was effective and appeared to be safe. Larger studies that also examine its application for gastric SMTs are warranted.

Abstract
AIM The aim of this meta-analysis is to assess the metabolic effects of bariatric surgery in type 2 diabetes mellitus (T2DM) patients with body mass index (BMI) < 35 kg/m(2) . METHODS We performed an electronic literature search of published articles to identify relevant evidence since inception to June 2011. Primary outcome measures were metabolic improvement and resolution diabetes after bariatric surgery. The weighted mean difference (WMD) and its 95% confidence interval (CI) were calculated from the raw data extracted from the original literature. The software Review Manager (version 4.3.1) was applied for meta-analysis. RESULTS Thirteen trials involving 357 patients were included in the meta-analysis. The follow-up interval ranged from 6 months to 18 years. According to WMD calculation, bariatric surgery led to 5.18 kg/m(2) of BMI lowering (95% CI, 3.79-6.57, p < 0.00001), 4.8 mmol/l of fasting plasma glucose (FPG) decrement (95% CI, 3.88-5.71 mmol/l, p < 0.00001), 2.59% of HbA1c decreasing (95% CI, 2.12-3.07%, p < 0.00001), 56.67 mg/dl of triglyceride decrement (95% CI 11.53-101.82, p = 0.01) and 48.38 mg/dl of total cholesterol reduction (95% CI 21.08-75.68, p = 0.0005). Moreover, the procedures produced an increased high-density lipoprotein cholesterol by 5.37 mg/dl (95% CI -11.37-0.63, p = 0.08). However, this effect was not statistically significant. Overall, 80.0% of the patients achieved adequate glycaemic control (HbA1c < 7%) without antidiabetic medication. The surgeries produced a low incidence of major complications (3.2%) with no mortality. CONCLUSIONS Bariatric surgery is effectual and safe in the treatment of non-severely obese (BMI < 35 kg/m(2) ) T2DM patients. Moreover, the metabolic benefits acquired from the procedures can be long sustained after the surgery.
