Abstract
Mannan derived from fungal cell walls have potential uses as immunomodulating agents and vaccine adjuvants. Immunization with antigen conjugated to oxidized mannan (OM) or reduced mannan (RM) have induced differential immune responses in mice. Yet, the adjuvant effect and differences in molecular profiles of OM and RM on APCs is unresolved. Here, we investigated the response of mouse bone marrow-derived DCs to OM and RM. OM and RM stimulated DCs to produce differential Th1/Th2-inducing cytokines in vitro. OM and RM-activated DCs stimulated allogeneic T-cell Th1 and Th2 polarization reaction. OM instruct DCs to stimulate Th1 responses via IL-12p70 production, which depends on the phosphorylation of p38, RM barely induce IL-12p70, but IL-10 and IL-4, and magnitude of ERK phosphorylation, which results in a Th2 bias. These findings indicate that OM and RM were potent adjuvant capable of directly initiating DC activation Th1 and Th2 polarization respectively.

Abstract
Significant changes usually take place in the internal metabolism of insects during metamorphosis. The glycolysis-tricarboxylic acid (glycolysis-TCA) pathway is important for energy metabolism. To elucidate its dynamics, the mRNA levels of genes involved in this pathway were examined in the midgut of Spodoptera litura during metamorphosis, and the pyruvate content was quantified. The expression patterns of these genes in response to starvation were examined, and the interaction between protein phosphatase 1 (PP1) and phosphofructokinase (PFK) was studied. The results revealed that the expression or activities of most glycolytic enzymes was down-regulated in prepupae and then recovered in some degree in pupae, and all TCA-related genes were remarkably suppressed in both the prepupae and pupae. Pyruvate was enriched in the pupal midgut. Taken together, these results suggest that insects decrease both glycolysis and TCA in prepupae to save energy and then up-regulate glycolysis but down-regulate TCA in pupae to increase the supply of intermediates for construction of new organs. The expression of all these genes were down-regulated by starvation, indicating that non-feeding during metamorphosis may be a regulator of glycolysis-TCA pathway in the midgut. Importantly, interaction between PP1 and PFK was identified and is suggested to be involved in the regulation of glycolysis.

Abstract
AIM Data on risk factors for portomesenteric venous thrombosis (PMVT) following abdominal surgery for ulcerative colitis (UC) are limited. The aim of this study was to investigate factors associated with PMVT after surgical treatment for UC. METHOD Patients who underwent restorative proctocolectomy (RPC) and ileal pouch-anal anastomosis (IPAA) including diverting ileostomy closure for medically refractory UC were identified from a prospectively maintained database. Patient-related, disease-related and treatment-related variables were collected. Univariable and multivariable analyses were performed to assess factors associated with PMVT. RESULTS Of the 521 patients completing surgical treatment for UC between 2006 and 2012, symptomatic PMVT occurred in 36 (7%), which resulted in a significantly increased hospital stay (P < 0.001). Patients developing PMVT were younger (P = 0.014), had a lower preoperative albumin level (P = 0.037) and were more likely to have been taking steroids within 1 month before surgery (P = 0.006). The combined incidence of PMVT was comparable between patients having a three-stage and two-stage management (6% vs. 8%, P = 0.43), but the relative incidence of PMVT after RPC + IPAA was 8%, significantly higher than the 4% after total abdominal colectomy (TAC) (P = 0.005) and the 2% after subsequent completion proctectomy (CP) + IPAA (P = 0.038). Multivariate analysis confirmed that RPC + IPAA was associated with a significantly greater risk of PMVT than CP + IPAA (OR = 4.9, P = 0.003) or TAC (OR = 3.5, P = 0.011). Preoperative steroid use was an independent factor for PMVT (OR = 5.8, P = 0.006). CONCLUSION Steroid use 1 month before surgery is associated with an increased risk of PMVT. A staged restorative proctocolectomy does not increase the overall incidence of PMVT.

Abstract
AIM The aim of this study was to develop a prognostic scoring system to predict the outcome of patients with unresectable metastatic colon cancer who received primary colon tumour resection. METHOD Patients with confirmed metastatic colon cancer treated at the Peking University Cancer Hospital between 2003 and 2012 were reviewed retrospectively. The correlation of clinicopathological factors with overall survival was analysed using the Kaplan-Meier method and the log-rank test. Independent prognostic factors were identified using a Cox proportional hazards regression model and were then combined to form a prognostic scoring system. RESULTS A total of 110 eligible patients were included in the study. The median survival time was 10.4 months and the 2-year overall survival (OS) rate was 21.8%. Age over 70 years, an alkaline phosphatase (ALP) level over 160 IU/l, ascites, a platelet/lymphocyte ratio (PLR) above 162 and no postoperative therapy were independently associated with a shorter OS in multivariate analysis. Age, ALP, ascites and PLR were subsequently combined to form the so-called AAAP scoring system. Patients were classified into high, medium and low risk groups according to the score obtained. There were significant differences in OS between each group (P < 0.001). CONCLUSION Age, ALP, ascites, PLR and postoperative therapy were independent prognostic factors for survival of patients with metastatic colonic cancer who underwent primary tumour resection. The AAAP scoring system may be a useful tool for surgical decision making.

Abstract
SETTING Four hospitals in China. OBJECTIVE To evaluate the clinical efficacy and safety of using bicyclol in conjunction with glucurolactone in preventing drug-induced liver injury (DILI) in tuberculosis (TB) patients suffering from underlying liver disease. DESIGN A total of 240 initially treated TB patients who were healthy hepatitis B carriers or had pure steatosis were randomised into two equal groups; both received an oral glucurolactone tablet 600 mg/day (200 mg three times daily) as basic liver protection. The test group also received 75 mg/day (25 mg three times daily) bicyclol tablets orally, while the control group received no other liver protection. The incidence of liver injury in the two groups, the adjustment or termination of anti-tuberculosis chemotherapy and any adverse reactions were assessed. RESULTS The incidence rate and level of severity of liver injury and the termination rate of anti-tuberculosis treatment in the test group were lower than that of the control group (P < 0.05). The overall time of occurrence of liver injury was significantly different between the two groups (P < 0.05). CONCLUSION Adding bicyclol to basic liver protectants may effectively and safely prevent the occurrence of anti-tuberculosis DILI in patients with underlying liver disease, and help simplify anti-tuberculosis treatment.

Abstract
Background: In contrast to the consistent evidence for obesity and colorectal cancer (CRC) risk, the impact of obesity in CRC patients is less clear. In a well-characterised cohort of CRC patients, we prospectively evaluated class I and class II obesity with survival outcomes. Methods: The CRC patients (N=634) were followed from the date of diagnosis until disease progression/first recurrence (progression-free survival (PFS)) or death (overall survival (OS)). Body mass index (BMI) was calculated from reported usual weight prior to diagnosis. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated in models adjusted for clinicopathologic, treatment, and lifestyle factors. Results: Over a median follow-up of 4 years, 208 (33%) patients died and 235 (37%) recurred or progressed. Class II obesity, as compared with either overweight or normal weight, was associated with an increased risk of death (HR and 95% CI: 1.55 (0.97–2.48) and 1.65 (1.02–2.68), respectively), but no clear association was observed with PFS. In analyses restricted to patients who presented as stages I–III, who reported stable weight, or who were aged <50 years, obesity was associated with a significant two- to five-fold increased risk of death. Conclusions: In CRC patients evaluated at a large cancer centre, severely obese patients experienced worse survival outcomes independent of many other factors.

Abstract
Cancer is a disease of genome instability and genomic alterations; now, genomic heterogeneity is rapidly emerging as a defining feature of cancer, both within and between tumors. Motivation for our pilot study of tumor heterogeneity in esophageal squamous cell carcinoma (ESCC) is that it is not well studied, but the highest incidences of esophageal cancers are found in China and ESCC is the most common type. We profiled the mutations and changes in copy number that were identified by whole-exome sequencing and array-based comparative genomic hybridization in multiple regions within an ESCC from two patients. The average mutational heterogeneity rate was 90% in all regions of the individual tumors in each patient; most somatic point mutations were nonsynonymous substitutions, small Indels occurred in untranslated regions of genes, and copy number alterations varied among multiple regions of a tumor. Independent Sanger sequencing technology confirmed selected gene mutations with more than 88% concordance. Phylogenetic analysis of the somatic mutation frequency demonstrated that multiple, genomically heterogeneous divergent clones evolve and co-exist within a primary ESCC and metastatic subclones result from the dispersal and adaptation of an initially non-metastatic parental clone. Therefore, a single-region sampling will not reflect the evolving architecture of a genomically heterogeneous landscape of mutations in ESCC tumors and the divergent complexity of this genomic heterogeneity among patients will complicate any promise of a simple genetic or epigenetic diagnostic signature in ESCC. We conclude that any potential for informative biomarker discovery in ESCC and targeted personalized therapies will require a deeper understanding of the functional biology of the ontogeny and phylogeny of the tumor heterogeneity.

Abstract
OBJECTIVES To investigate whether colour Doppler ultrasonography (CDUS) can be used to detect the effect of adalimumab on sacroiliitis and peripheral enthesitis in patients with ankylosing spondylitis (AS). METHODS AS patients (n=41) received 40 mg adalimumab every other week for 24 weeks. BASDAI, BASFI, CRP, MRI examinations of the sacroiliac joints (SIJs) and CDUS examinations of both SIJs and 10 peripheral entheseal sites were taken at baseline, week 12, and week 24. We scored the MR images by SPARCC method, recorded the resistive index (RI) value of SIJs and graded the blood signal on a semi quantitative 0-3 scale. We also scored lesions of peripheral entheses seen by CDUS. We analysed the associations between the results of CDUS and clinical indices and MRI data. RESULTS Significant reduction in mean CDUS score of SIJs and peripheral enthesitis and increase in mean RI value were observed in AS patients treated with adalimumab for 12 weeks and 24 weeks as compared with baseline (all p<0.05). The CDUS scores of SIJs and peripheral enthesitis positively related with clinical assessments (including BASDAI, BASFI, and CRP), while the RI value negatively related with them at all visits (all p<0.05). The results of CDUS also correlated well with the MRI data (all p<0.05) during adalimumab treatment in AS patients. CONCLUSIONS Our study found that CDUS could be used to detect the changes of sacroiliitis and peripheral enthesitis in AS patients under adalimumab therapy.

Abstract
Nucleotide sequencing of the phylogenetically informative region of NS5B remains the gold standard for hepatitis C virus (HCV) genotyping. Here we developed a new methodology for sequencing new NS5B regions to increase the accuracy and sensitivity of HCV genotyping and subtyping. The eight new primers were identified by scanning the full-length NS5B regions from 1127 HCV genomic sequences found in HCV databases. The ability of each pair of primers to amplify HCV subtypes was scored, and the new primers were able to amplify the NS5B region better than the previously used primers, therefore more accurately subtyping HCV strains. Sequencing the DNA amplified by the new primer pairs can specifically and correctly detect the five standard HCV subtypes (1a, 2a, 3b, 6a and 1b). We further examined patient samples and found that the new primers were able to identify HCV subtypes in clinical samples with high sensitivity. This method was able to detect all subtypes of HCV in 567 clinical samples. Importantly, three novel HCV subtypes (1b-2a, 1b-2k and 6d-6k) were identified in the samples, which have not been previous reported in China. In conclusion, sequencing the NS5B region amplified by the new NS5B primers is a more reliable method of HCV genotyping and a more sensitive diagnostic tool than sequencing using the previously described primers, and could identify new HCV subtypes. Our research is useful for clinical diagnosis, guidance of clinical treatment, management of clinical patients, and studies on the epidemiology of HCV.

Abstract
Here we introduce a novel method of transplanting human fetal kidneys into adult rats. To overcome the technical challenges of fetal-to-adult organ transplantation, we devised an arterial flow regulator (AFR), consisting of a volume adjustable saline-filled cuff, which enables low-pressure human fetal kidneys to be transplanted into high-pressure adult rat hosts. By incrementally withdrawing saline from the AFR over time, blood flow entering the human fetal kidney was gradually increased until full blood flow was restored 30 days after transplantation. Human fetal kidneys were shown to dramatically increase in size and function. Moreover, rats which had all native renal mass removed 30 days after successful transplantation of the human fetal kidney were shown to have a mean survival time of 122 days compared to 3 days for control rats that underwent bilateral nephrectomy without a prior human fetal kidney transplant. These in vivo human fetal kidney models may serve as powerful platforms for drug testing and discovery.

Abstract
Stanniocalcin 1 (STC1) is a hypocalcemic hormone that is known to play an important role in calcium metabolism in teleost fish. An increase in blood Ca(2) (+) levels stimulates its synthesis and release. The biological action of STC1 inhibits gill Ca(2) (+) transport (GCAT), but we as yet have no clear understanding of how STC1 inhibits GCAT. In the present study, we characterized the binding, signaling, and action of STC1 on gill cells. Treatment of gill cell cultures with the extracts of corpuscles of Stannius or recombinant STC1 proteins (STC1-V5) led to an increase in cytosolic cAMP levels. Using in situ ligand-binding assays, we demonstrated that STC1-V5 binds to both lamellar and inter-lamellar regions of gill sections. The binding sites were significantly increased in gill sections obtained from fish adapted to high-Ca(2) (+) (2 mM) freshwater (FW) as compared with those from fish adapted to low-Ca(2) (+) (0.2 mM) FW. Receptor-binding assays illustrated specific binding of STC1-alkaline phosphatase to plasma membrane (Kd of 0.36 nM), mitochondria (Kd of 0.41 nM), and nuclear (Kd of 0.71 nM) preparations from gill cells. STC1 binding capacity was significantly greater in the plasma membrane preparations of gills obtained from fish adapted to high-Ca(2) (+) FW. Using isolated pavement cells and mitochondria-rich cells in cAMP assays, we obtained results indicating that both cell types responded to STC1. To illustrate the biological action of STC1, we conducted Ca(2) (+) imaging experiments to demonstrate the effects of STC1 on thapsigargin-induced elevation of cytosolic Ca(2) (+). Our results indicated that STC1 exerted its inhibitory action via a cAMP pathway to lower intracellular Ca(2) (+) levels. Intriguingly, we were able to block the action of STC1 using an inhibitor, NS-398, of cyclooxygenase-2 (COX-2), which is known to stimulate the activity of sarcoplasmic and endoplasmic reticulum Ca(2) (+)-ATPase (SERCA). A follow-up experiment in which gill cells were incubated with STC1 revealed a downregulation of the epithelial Ca(2) (+) channel (ecacl) but an upregulation of cox-2 expression. The ECaCl is a gatekeeper for Ca(2) (+) entry, whereas COX-2 mediates an activation of SERCA. Taking these results together, the present study is, to our knowledge, the first to provide evidence of STC1 binding and signaling as well as the first to decipher the mechanism of the effect of STC1 on fish gills.

Abstract
BACKGROUND & AIMS The Drug-Induced Liver Injury Network is conducting a prospective study of patients with DILI in the United States. We present characteristics and subgroup analyses from the first 1257 patients enrolled in the study. METHODS In an observational longitudinal study, we began collecting data on eligible individuals with suspected DILI in 2004, following them for 6 months or longer. Subjects were evaluated systematically for other etiologies, causes, and severity of DILI. RESULTS Among 1257 enrolled subjects with suspected DILI, the causality was assessed in 1091 patients, and 899 were considered to have definite, highly likely, or probable DILI. Ten percent of patients died or underwent liver transplantation, and 17% had chronic liver injury. In the 89 patients (10%) with pre-existing liver disease, DILI appeared to be more severe than in those without (difference not statistically significant; P = .09) and mortality was significantly higher (16% vs 5.2%; P < .001). Azithromycin was the implicated agent in a higher proportion of patients with pre-existing liver disease compared with those without liver disease (6.7% vs 1.5%; P = .006). Forty-one cases with latency ≤7 days were caused predominantly by antimicrobial agents (71%). Two most common causes for 60 DILI cases with latency >365 days were nitrofurantoin (25%) or minocycline (17%). There were no differences in outcomes of patients with short vs long latency of DILI. Compared with individuals younger than 65 years, individuals 65 years or older (n = 149) were more likely to have cholestatic injury, although mortality and rate of liver transplantation did not differ. Nine patients (1%) had concomitant severe skin reactions; implicated agents were lamotrigine, azithromycin, carbamazepine, moxifloxacin, cephalexin, diclofenac, and nitrofurantoin. Four of these patients died. CONCLUSIONS Mortality from DILI is significantly higher in individuals with pre-existing liver disease or concomitant severe skin reactions compared with patients without. Additional studies are needed to confirm the association between azithromycin and increased DILI in patients with chronic liver disease. Older age and short or long latencies are not associated with DILI mortality.

Abstract
Hypertension is a major traditional risk factor for atherosclerosis, and carotid artery intima-media thickness (IMT) is considered to be an important marker of atherosclerosis. Sulfatides have been shown to play a role in atherogenesis and vascular inflammation, resulting in atherosclerosis. This study aimed to assess the association between serum sulfatide and carotid artery IMT among hypertensive patients. We chose 60 hypertensive patients and 30 matched healthy controls. All subjects had medical examinations at Hebei General Hospital between March 2011 and March 2012. Measurements and other factors compared included serum sulfatide level, carotid artery IMT, and conventional cardiovascular risk factors. Hypertensive patients had higher BMIs (24.4 ± 7.6 to 23.1 ± 3.1 kg/m(2)), total cholesterol levels (5.5 ± 0.6 to 5.0 ± 1.1 mM), serum sulfatide levels (3.5 ± 3.9 to 8.3 ± 2.7 μM), and carotid artery IMTs (1.06 ± 0.15 to 0.79 ± 0.07 mm) (all P < 0.05) than control patients. Furthermore, the serum sulfatide level positively correlated with carotid IMT in the hypertensive patients (r = 0.39, P = 0.002). Multiple linear regression analysis showed serum sulfatide was an independent risk factor affecting IMT (P = 0.04). These results suggest that serum sulfatide is more strongly associated with carotid artery IMT than other traditional risk factors in hypertensive patients.

Abstract
Athletic performance is influenced by a complex interplay among the environment and a suite of genes, which contributes to system-wide structure and function. In a panel of elite and non-elite Thoroughbred horses (n=148), we genotyped 68 SNPs in 17 putative exercise-relevant genes chosen from a genome scan for selection. We performed a series of case-control and quantitative association tests for relationships with racecourse performance. Thirteen SNPs in nine genes were significantly (P<0.05) associated with a performance phenotype. We selected five SNPs in four genes (ACSS1, ACN9, COX4I1, PDK4) for validation in an independent sample set of elite and non-elite Thoroughbreds (n=130). Two SNPs in the PDK4 gene were validated (P<0.01) for associations with elite racing performance. When all samples were considered together (n=278), the PDK4_ 38973231 SNP was strongly associated (P<0.0005) with elite racing performance. Individuals with the A:A and A:G genotypes had a 16.2-16.6 lb advantage over G:G individuals in terms of handicap rating. Re-sequencing of the PDK4 gene and further genotyping will be required to identify the causative variant that is likely influencing exercise-induced variation in expression of the gene. Notwithstanding, this information may be employed as a marker for the selection of racehorses with the genetic potential for superior racing ability.

Abstract
AIM A study was carried out with the aim of identifying potential factors which might influence the fate of patients undergoing faecal diversion by stoma in perianal Crohn's disease. METHOD Patients with severe perianal Crohn's disease undergoing faecal diversion between 1994 and 2012 were identified and the factors associated with stoma closure were assessed using univariate and multivariate analysis. RESULTS Of 138 diverted patients, 30 (22%) achieved stoma closure, 45 (33%) had a stoma with the rectum left in situ and 63 (45%) underwent proctectomy with permanent stoma formation after a mean follow-up of 5.7 years. Univariate analysis demonstrated that synchronous colonic (P = 0.004) or rectal (P = 0.021) disease involvement and an increased frequency of loose seton placement (P = 0.001) adversely affected successful stoma closure rates. Multivariate analysis indicated a significant association between the inability to achieve stoma closure and persisting rectal involvement (OR 7.5, 95% CI 2.4-33.4), one or two placements of a loose seton (OR 3.3, 95% CI 1.4-8.8) and more than two placements (OR 6.9, 95% CI 1.2-132.5). No specific medical management was associated with an improved stoma closure rate, including biological agents when these were available (P = 0.25). CONCLUSION The fate of temporary faecal diversion in patients with perianal Crohn's disease is adversely affected by aggressive disease characteristics. No particular treatment, including biological therapy, was associated with an improved outcome.

Abstract
UNLABELLED Insulin resistance has a close relationship with tumorigenesis, tumor progression, and cancer prognosis. Importantly, the liver is the main target tissue of insulin, and the resistance to chemotherapeutic agents has been reported in hepatocarcinoma. However, little is known about the relationship between drug resistance and insulin resistance in hepatocarcinoma. Therefore, we treated HepG2 cells (a human hepatoma cell line) with high concentrations of insulin to establish a cell-based model of insulin resistance (HepG2/IR cells) to define the relationship between insulin resistance and the resistance to chemotherapy. We identified that HepG2/IR cells exhibited stable insulin resistance, with decreased glucose consumption, reduced glycogen synthesis, and decreased expression of the insulin receptor gene. HepG2/IR cells also exhibited endoplasmic reticulum (ER) dilatation and degranulation. Molecular markers of endoplasmic reticulum stress, including glucose-regulated protein78 (GRP78) and phosphorylated protein kinase R-like ER kinase (p-PERK), increased significantly, which was accompanied by increased reactive oxygen metabolism and decreased mitochondrial membrane potential. In addition, HepG2/IR cells were resistant to the chemotherapy agent Adriamycin, which was accompanied by the upregulation of multidrug resistance gene 1/ P-glycoprotein (P-gp; an endoplasmic reticulum chaperone that plays a role in ER stress), and enhanced drug efflux. These data suggest that the endoplasmic reticulum (ER) stress response was active in HepG2/IR cells, and that insulin resistance was related to drug resistance in HepG2 cells. Interestingly, the ER stress and chemotherapy resistance observed in HepG2/IR cells could be reversed by treatment with the insulin sensitizer pioglitazone. Therefore, our study suggests that there is a close relationship between the resistance to chemotherapy and insulin resistance in HepG2 cells, and that the ER stress response play a role in insulin resistance-mediated drug resistance in hepatocarcinoma cells. KEYWORDS Insulin resistance, drug resistance, P-gp, endoplasmic reticulum stress, HepG2 cells.

Abstract
Mounting evidence suggests that brain inflammation mediated by glial cells may contribute to epileptogenesis. Minocycline is a second-generation tetracycline and has potent antiinflammatory effects independent of its antimicrobial action. The present study aimed to investigate whether minocycline could exert antiepileptogenic effects in a rat lithium-pilocarpine model of temporal lobe epilepsy. The temporal patterns of microglial and astrocytic activation were examined in the hippocampal CA1 and the adjacent cortex following pilocarpine-induced status epilepticus (SE). These findings displayed that SE caused acute and persistent activation of microglia and astrocytes. Based on these findings, Minocycline was administered once daily at 45 mg/kg for 14 days following SE. Six weeks after termination of minocycline treatment, spontaneous recurrent seizures (SRS) were recorded by continuous video monitoring. Minocycline inhibited the SE-induced microglial activation and the increased production of interleukin-1β and tumor necrosis factor-α in the hippocampal CA1 and the adjacent cortex, without affecting astrocytic activation. In addition, Minocycline prevented the SE-induced neuronal loss in the brain regions examined. Moreover, minocycline significantly reduced the frequency, duration, and severity of SRS during the two weeks monitoring period. These results demonstrated that minocycline could mitigate SE-induced brain inflammation and might exert disease-modifying effects in an animal model of temporal lobe epilepsy. These findings offer new insights into deciphering the molecular mechanisms of epileptogenesis and exploring a novel therapeutic strategy for prevention of epilepsy.
