Abstract
OBJECTIVE Fibroblast growth factor 21 (FGF21) exerts beneficial effects on metabolic homoeostasis and has been reported to be regulated by adiponectin, leptin and resistin. However, while an association between increased circulating FGF21 and metabolic disorders has been reported in adults, paediatric-specific data are lacking. DESIGN AND METHODS This study investigated the relationship between FGF21 levels and obesity, insulin resistance (IR), the metabolic syndrome (MetS) and adipokines (adiponectin, leptin and resistin) in a cohort of 3231 Chinese youngsters aged 6-18. RESULTS There were gender- and puberty-related differences in FGF21 levels. Unexpectedly, FGF21 levels were decreased in children with obesity, and negatively correlated with insulin, HOMA-IR and leptin levels after adjusting for age, gender, puberty and lifestyle factors. Moreover, multiple regression analyses showed that serum FGF21 positively predicted adiponectin levels while resistin positively predicted FGF21 levels independent of BMI (P<0.05). Children in the lowest FGF21 quintile were more likely to have IR (OR: 1.85, 95% CI: 1.41-2.42; P=0.002) and MetS (OR: 1.62, 95% CI: 1.14-2.28; P=0.007) than those in the highest quintile. Further adjusting for BMI and/or the three adipokines modified the association of FGF21 with MetS (P>0.10) but not with IR (P<0.01). CONCLUSION Although the associations between adiponectin, leptin, resistin and metabolic abnormalities in our paediatric population were similar to those in adults, correlations of FGF21 levels with obesity, IR and MetS were the inverse of those found in adults. Our present findings suggest that FGF21 deficiency, rather than resistance, contribute to IR and hypoadiponectinaemia independently of obesity in young people.

Abstract
The Ras-related C3 botulinum toxin substrate 1 (RAC1), a member of the Rho family of small guanosine triphosphatases, is critical for many cellular activities, such as phagocytosis, adhesion, migration, motility, cell proliferation, and axonal growth. In addition, RAC1 plays an important role in cancer angiogenesis, invasion, and migration, and it has been reported to be related to most cancers, such as breast cancer, gastric cancer, testicular germ cell cancer, and lung cancer. Recently, the therapeutic target of RAC1 in cancer has been investigated. In addition, some investigations have shown that inhibition of RAC1 can reverse drug-resistance in non-small cell lung cancer. In this review, we summarize the recent advances in understanding the role of RAC1 in lung cancer and the underlying mechanisms and discuss its value in clinical therapy.

Abstract
Objective: To assess the association between baseline body mass index (BMI) and risk of lung cancer in non-smoking males. Methods: A dynamic non-smoking male cohort was established on May, 2006. Baseline information on demography, lifestyle, such as smoking status and alcohol consumption, anthropometry, such as body height and weight, were collected during the baseline interview, and the information of newly-diagnosed lung cancer cases were also collected during the follow-up period. Multivariable Cox proportional-hazards regression model was used to analyze the association between baseline BMI and lung cancer in non-smoking males. Results: By December 31, 2011, a total of 48 799 male non-smokers had been assessed in the study and there were 214 620.18 person-years of follow-up and 4.40 years of average follow-up period. During follow-up, 198 lung cancer cases were identified among the 48 799 non-smoking males. Compared with those with normal BMI (kg/m2) (18.5≤BMI<24.0), the hazard ratio (95%CI) of lung cancer were 1.14(0.53-2.45), 0.57(0.41-0.78) and 0.61(0.38-0.97) for underweight (BMI<18.5), overweight (24.0≤BMI<28.0) and obese males (≥28.0), respectively, after adjustment for potential confounding factors, including age, education level, alcohol consumption, physical activity, history of diabetes and work environment. Baseline BMI was negatively associated with the risk of lung cancer in non-smoking males and the risk would be reduced by 22% (HR=0.78, 95% CI: 0.64-0.95) for per 5 kg/m2 BMI increase. The negative association between BMI and risk of lung cancer was significant among non-smoking males who aged ≥50 years, and in those who had physical exercise <4 times/week, never drunk and worked above the coal mine, and for per 5 kg/m2 BMI increase, the risk of lung cancer would be reduced by 26%(HR=0.74, 95%CI: 0.60-0.92), 24%(HR=0.76, 95%CI: 0.62-0.95), 20% (HR=0.80, 95%CI: 0.65-1.00) and 23% (HR=0.77, 95%CI: 0.61-0.97), respectively. The result was similar after excluding the cancer patients newly diagnose within 1-year and their contribution person years. Conclusion: Baseline BMI might be negatively associated with risk of lung cancer in non-smoking males.

Abstract
OBJECTIVE To deepen the understanding of acquired von Willebrand syndrome (AVWS). METHODS The clinical data of 3 patients were analyzed and related literature were reviewed. RESULTS ① Case 1, a 70- year- old male, diagnosed as Waldenstrom macroglobulinemia and AVWS, was presented with spontaneous epitaxis and bruising. The VWF∶Ag level was 16%. Treatment was initiated with VWF concentrates. Two cycles of chemotherapy with Bortezomib, thalidomide and Dexamethasone were followed. Partial remission was achieved. Half- year' follow- up showed no sign of spontaneous hemorrhage. ② Case 2, a 48- year- old female, diagnosed as monoclonal gammopathy of undetermined significance and AVWS, was presented with repeated epitaxis. The VWF∶Ag level was 7%. Because the bleeding was slight and self-relieved, no specific treatment was addressed. She was followed up for one and a half year. ③ Case 3, a 50- year- old man, diagnosed as monoclonal gammopathy of undetermined significance and AVWS, was referred to our hospital for presentation with significant hematomas. VWF∶ Ag was reduced to 12%. VWF- containing cryoprecipitate, plasma, intravenous immunoglobulin and rituximab were used to control his bleeding symptom. During the follow-up, spontaneous hemorrhage still occurred occasionally. CONCLUSIONS Acquired von Willebrand syndrome presented with heterogeneous symptoms. The level of VWF∶Ag and VWF∶Rco for patients with bleeding disorder should be performed. Abnormal bleeding symptoms in elderly patients without personal or family history of bleeding should prompt consideration of the underlying disorders. Treatment included controlling acute bleeding, curing the underlying diseases and preventing bleeding in high- risk situations. The prognosis of acquired von Willebrand syndrome is mainly related to the underlying diseases.

Abstract
OBJECTIVE To investigate the role and potential molecular mechanism of Galectin-3 (Gal-3) in the etiology of endometriosis-associated infertility. METHODS We detected Gal-3 expression in eutopic endometrium from women with endometriosis-associated infertility and healthy women without endometriosis or infertility. We then evaluated Gal-3 expression in endometrial glandular epithelial cells (EECs) and endometrial stromal cells (ESCs) and investigated its response to hormone stimulation in EECs and ESCs from both groups of women. RESULTS Results of real-time PCR and western blot analysis showed Gal-3 expression in both proliferative and secretory stages of the menstrual cycle decreased significantly in women with endometriosis-associated infertility compared to healthy women. The changes in expression of Gal-3 were more dramatic in EECs than ESCs. Moreover, estrogen (E2) and progesterone (P4) induced Gal-3 expression in EECs of healthy groups, and P4 was more significant than E2 and combined E2 and P4 (E2P4). However, in the endometriosis group, P4 failed to induce a similar increase in Gal-3 expression. CONCLUSIONS Our results suggest that aberrant expression of Gal-3 might contribute to infertility in patients with endometriosis due to progesterone resistance.

Abstract
Acute erythroid leukemia (AEL), characterized by a predominant erythroid proliferation, is a subtype of acute myelogenous leukemia. The genetic basis of AEL remains poorly defined. Through whole-exome sequencing, we identified high frequencies of mutations in CEBPA (32.7%), GATA2 (22.4%), NPM1 (15.5%), SETBP1 (12.1%) and U2AF1 (12.1%). Structure prediction analysis revealed that most of the GATA2 mutations were located at the DNA-binding N-terminal zinc-finger near the DNA-binding interface, suggesting that mutations could result in at least partial inactivation of GATA2 protein. On co-transfection of a GATA-responsive reporter construct together with plasmids expressing either GATA2 wild-type or GATA2 ZF1 mutants (P304H, L321P and R330X) in 293T cells, we found a reduced transcriptional activation in cells transfected with GATA2 mutants. To determine whether reduced GATA2 function is involved in leukemogenesis of AEL, we transfected 32D cells with GATA2 mutants and evaluated the impact of GATA2 mutations on erythroid differentiation. Our data revealed an increased expression of erythroid-related antigens Ter-119, β-globin and βh1-globin, as well as increased hemoglobin positivity in 32D cells transfected with GATA2 mutants compared with control cells. Our results suggest that the decline of GATA2 resulting from mutations contributes to the erythroid commitment, differentiation and the development of AEL.

Abstract
Deoxynivalenol (DON) causes various toxic effects in human and animals. However, our previous studies have shown that composite antimicrobial peptides (CAP) can have a protective effect in piglets challenged with DON. This study was conducted to evaluate the effect of the CAP GLAM 180# on the metabolism of piglets challenged with DON using a nuclear magnetic resonance (NMR)-based metabolomics approach. A total of 28 individually housed piglets (Duroc × Landrace × Large Yorkshire) weaned at 28 d of age were randomly assigned into 4 treatment groups (7 pigs/treatment) based on a 2 × 2 factorial arrangement that were fed, respectively, a basal diet (NC), basal diet + 0.4% CAP (basal + CAP), basal diet + 4 mg/kg DON (basal + DON), and basal diet + 4 mg/kg DON + 0.4% CAP (DON + CAP). A 7-d adaptation period was followed by 30 d of treatment. Blood samples were then collected for metabolite analysis by proton NMR (H-NMR) spectroscopy and liquid chromatography tandem mass spectrometry (LC-MS/MS). The combined results of H-NMR spectroscopy and LC-MS/MS showed that DON increased ( < 0.05) the serum concentrations of low-density lipoprotein, glycoprotein, urea, trimethylamine-N-oxide (TMAO), and lactate as well as those of almost all essential AA and some nonessential AA but decreased the concentrations of high-density lipoprotein (HDL), unsaturated lipids, citrate, choline, and fumarate compared with those in NC treatment ( < 0.05). There was a significant interaction effect ( < 0.05) of supplementation with DON and CAP on some metabolites showed that the serum concentrations of HDL, unsaturated lipids, Pro, citrate, and fumarate were greater ( < 0.05) whereas those of glycoprotein, urea, TMAO, Gly, and lactate were lower in the DON + CAP treatment compared with those in the basal + DON treatment ( < 0.05). These findings indicated that DON causes disturbances in AA, lipid, and energy metabolism and that CAP could partially attenuate the above metabolic disturbances induced by DON.

Abstract
OBJECTIVE To assess the feasibility and effects of identifying tuberculosis (TB) cases by integrating TB screening into routine health examinations for the elderly in rural China. METHODS Three counties in Shandong Province were randomly selected for TB screening among three groups of elderly individuals (aged ⩾60 years) at high risk for TB: 1) those with symptoms of TB, 2) patients with type 2 diabetes mellitus (DM), and 3) close contacts of TB cases. Individuals with X-rays suggestive of TB were referred to the county TB dispensary for further investigation. RESULTS Among the 93 094 elderly residents who underwent health examinations, 9044 (9.7%) were identified as high risk for TB. TB detection rates were 0.87 per 1000 among those who showed TB symptoms only and 3.36/1000 among those with DM only; however, the rate was significantly higher (115/1000) among those who had both DM and TB symptoms. No TB cases were identified from the close contacts group. CONCLUSION Integrating TB screening into annual health examinations for the elderly in rural areas was effective in identifying new cases, especially among elderly DM patients with TB symptoms.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of current universal infant rotavirus vaccination strategy, in China. METHODS Through constructing decision tree-Markov model, we simulated rotavirus diarrhea associated cost and health outcome on those newborns in 2012 regarding different vaccination programs as: group with no vaccination, Rotavirus vaccination group and Rotateq vaccination group, respectively. We determined the optimal program, based on the comparison between incremental cost-effectiveness ratio (ICER) and China' s 2012 per capital gross domestic product (GDP). RESULTS Compared with non-vaccination group, the Rotavirus vaccination and Rotateq vaccination groups had to pay 3 760 Yuan and 7 578 Yuan (both less than 2012 GDP per capital) to avert one disability adjusted life years (DALY) loss, respectively. RESULTS from sensitivity analysis indicated that both results were robust. Compared with Rotavirus vaccination program, the Rotateq vaccination program had to pay extra 81 068 Yuan (between 1 and 3 times GDP per capital) to avert one DALY loss. Data from the sensitivity analysis indicated that the result was not robust. CONCLUSION From the perspective of health economics, both two-dose Rotarix vaccine and three-dose' s Rotateq vaccine programs were highly cost-effective, when compared to the non-vaccination program. It was appropriate to integrate rotavirus vaccine into the routine immunization program. Considering the large amount of extra cost that had to spend on Rotateq vaccination program, results from the sensitivity analysis showed that it was not robust. Rotateq vaccine required one more dose than the Rotarix vaccine, to be effective. However, it appeared more difficult to practice, suggesting that it was better to choose the Rotarix vaccine, at current stage.

Abstract
A smart core-sheath nanofiber for non-adherent cell capture and release is demonstrated. The nanofibers are fabricated by single-spinneret electrospinning of poly(N-isopropylacrylamide) (PNIPAAm), polycaprolactone (PCL) and nattokinase (NK) solution blends. The self-assembly of PNIPAAm and PCL blends during the electrospinning generates the core-sheath PCL/PNIPAAm nanofibers with PNIPAAm as the sheath. The PNIPAAm-based core-sheath nanofibers are switchable between hydrophobicity and hydrophilicity with temperature change and enhance stability in the blood. When the nanofibers come in contact with blood, the NK is released from the nanofibers to resist platelet adhesion on the nanofiber surface, facilitating the direct capture and isolation of red blood cells (RBCs) from the blood above phase-transition temperature of PNIPAAm. Meanwhile, the captured RBCs are readily released from the nanofibers with temperature stimuli in an undamaged manner. The release efficiency of up to 100% is obtained while maintaining cellular integrity and function. This work presents promising nanofibers to effectively capture non-adherent cells and release for subsequent molecular analysis and diagnosis of single cells.

Abstract
OBJECTIVE Lead is a common environmental contaminant. Lead accumulation in the body is especially dangerous for pregnant women and newborns. Selenium is a trace element which may rectify the damaging effects of lead. Here we tested potential protective effects of selenium against gestational lead exposure. MATERIALS AND METHODS Pregnant SD rats were exposed to 200 mg/L of lead acetate (given with water), with or without sodium selenite supplementation (2-8 mg/kg/day via intragastric administration). Pregnant rats not exposed to lead or selenium served as control animals. The outcomes in pregnant rats were serum lead and selenium levels, reproductive hormone (follicle-stimulating hormone, luteinizing hormone, prolactin, oestradiol, progesterone) levels, and uterine and ovarian morphological changes. The outcomes in the offspring were sex differentiation, survival rates (day 21 after birth), weight (days 0-35 after birth), weight of reproductive organs, and puberty onset (foreskin separation or vaginal opening). RESULTS Selenium supplementation dose-dependently decreased serum lead levels, rectified reproductive hormone levels, and attenuated reproductive morphological changes caused by lead exposure. Lead exposure did not affect sex differentiation, but significantly (p < 0.05 vs. control animals) decreased the offspring weight on days 0-28 and the weight of their reproductive organs. Furthermore, lead exposure delayed the onset of puberty. These pathological changes were dose-dependently rectified or attenuated by selenium supplementation. CONCLUSIONS Gestational lead exposure causes damages to the reproductive system of pregnant rats, and negatively modulates growth and reproductive system development of the offspring. These adverse effects are rectified or attenuated by selenium supplementation.

Abstract
Odorant-binding proteins (OBPs) play an important role in insect olfactory processes and are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors within the antennal sensilla. As an important general odorant binding protein in the process of olfactory recognition, LstiGOBP1 of Loxostege sticticalis L. has been shown to have good affinity to various plant volatiles. However, the binding specificity of LstiGOBP1 should be further explored in order to better understand the olfactory recognition mechanism of L. sticticalis. In this study, real-time PCR experiments indicated that LstiGOBP1 was expressed primarily in adult antennae. Homology modelling and molecular docking were then conducted on the interactions between LstiGOBP1 and 1-heptanol to understand the interactions between LstiGOBP1 and their ligands. Hydrogen bonds formed by amino acid residues might be crucial for the ligand-binding specificity on molecular docking, a hypothesis that was tested by site-directed mutagenesis. As predicted binding sites for LstiGOBP1, Thr15, Trp43 and Val14 were replaced by alanine to determine the changes in binding affinity. Finally, fluorescence assays revealed that the mutants Thr15 and Trp43 had significantly decreased binding affinity to most odours; in mutants that had two-site mutations, the binding to the six odours that were tested was completely abolished. This result indicates that Thr15 and Trp43 were involved in binding these compounds, possibly by forming multiple hydrogen bonds with the functional groups of the ligands. These results provide new insights into the detailed chemistry of odours' interactions with proteins.

Abstract
To compare the genetic population structure of Staphylococcus aureus from China and Europe, 1294 human isolates were characterized by multiple-locus variable number tandem repeat analysis (MLVA). In total, MLVA identified 17 MLVA complexes (MCs), comprising 260 MLVA types (MTs) among the Chinese isolates and 372 MTs among the European isolates. The five most frequent MCs among the Chinese isolates belonged to MC398, MC5 subclade a, MC8, MC437 and MC7 and made up 55% of the sample. For the European isolates, the five most frequent MCs consisted of MC5 subclade a, MC45, MC8, MC30 and MC22, which accounted for 64% of the sample. Phylogeographic analysis of the major MCs shared between China and Europe points to a European origin of MC8 but cannot provide a consistent signal for MC5 subclade a, probably indicating a different origin. Diversity and frequency distributions of other lineages were also compared. Altogether, this study provides the first snapshot of two extant populations of S. aureus from Europe and China, and important clues on the emergence and dissemination of different lineages of S. aureus.

Abstract
Sigma-1 receptor (σ1R) has been reported to be decreased in nigrostriatal motor system of Parkinson's disease patients. Using heterozygous and homozygous σ1R knockout (σ1R+/- and σ1R-/-) mice, we investigated the influence of σ1R deficiency on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-impaired nigrostriatal motor system. The injection of MPTP for 5 weeks in wild-type mice (MPTP-WT mice), but not in σ1R+/- or σ1R-/- mice (MPTP-σ1R+/- or MPTP-σ1R-/- mice), caused motor deficits and ~40% death of dopaminergic neurons in substantia nigra pars compacta with an elevation of N-methyl-d-aspartate receptor (NMDAr) NR2B phosphorylation. The σ1R antagonist NE100 or the NR2B inhibitor Ro25-6981 could alleviate the motor deficits and the death of dopaminergic neurons in MPTP-WT mice. By contrast, MPTP-σ1R+/- mice treated with the σ1R agonist PRE084 or MPTP-σ1R-/- mice treated with the NMDAr agonist NMDA appeared to have similar motor deficits and loss of dopaminergic neurons as MPTP-WT mice. The pharmacological or genetic inactivation of σ1R suppressed the expression of dopamine transporter (DAT) in substantia nigra, which was corrected by NMDA. The activation of σ1R by PRE084 enhanced the DAT expression in WT mice or σ1R+/- mice. By contrast, the level of vesicular monoamine transporter 2 (VMAT2) in σ1R+/- mice or σ1R-/- mice had no difference from WT mice. Interestingly, MPTP-WT mice showed the reduction in the levels of DAT and VMAT2, but MPTP-σ1R-/- mice did not. The inactivation of σ1R by NE100 could prevent the reduction of VMAT2 in MPTP-WT mice. In addition, the activation of microglia cells in substantia nigra was equally enhanced in MPTP-WT mice and MPTP-σ1R-/- mice. The number of activated astrocytes in MPTP-σ1R-/- mice was less than that in MPTP-WT mice. The findings indicate that the σ1R deficiency through suppressing NMDAr function and DAT expression can reduce MPTP-induced death of dopaminergic neurons and parkinsonism.

Abstract
Bladder cancer occurs in the majority of cases in males, which represents the fourth highest incident cancer in men and tenth in women. It is associated with a high rate of recurrence, and prognosis is poor once the cancer metastasizes to distant sites. Transitional cell cancer (TCC) is the most predominant histological type. Bladder cancer is highly chemosensitive. However, the presence of acquired drug resistance is one of the primary impediments to the success of chemotherapy. To differentiate and delineate the molecular events, we developed drug resistant human transitional bladder cancer T24 cells (DRC) by treating cells with the increasing concentration of vinblastine. We found that DRC was resistant to vinblastine in comparison to parental T24 cells. We analyzed the contributory factors that may be involved in the development of resistance. As expected, expression of permeability glycoprotein (P—gp) was up—regulated in DRC. In addition, levels of Caveolin—1 (Cav—1), Fatty acid synthase (FASN) and Cytochrome P450 (CYP450) were elevated in DRC. Downregulation of these proteins by respective specific pharmacological inhibitors and/or by siRNAs resensitized cells to vinblastine. These results suggested that differential levels of P—gp, Cav—1 and FASN except CYP450 play a major role in acquired resistant phenotype in bladder cancer.

Abstract
Influenza virus (IV) infection is a major public health problem, causing millions of cases of severe illness and as many as 500 000 deaths each year worldwide. Given the limitations of current prevention or treatment of acute influenza, novel therapies are needed. RNA interference (RNAi) through microRNAs (miRNA) is an emerging technology that can suppress virus replication in vitro and in vivo. Here, we describe a novel strategy for the treatment of infuenza based on RNAi delivered by a replication-defective adenovirus (Ad) vector, derived from chimpanzee serotype 68 (AdC68). Our results showed that artificial miRNAs (amiRNAs) specifically targeting conserved regions of the IV genome could effectively inhibit virus replication in human embryonic kidney 293 cells. Moreover, our results demonstrated that prophylactic treatment with AdC68 expressing amiRNAs directed against M1, M2 or nucleoprotein genes of IV completely protected mice from homologous A/PR8 virus challenge and partially protected the mice from heterologous influenza A virus strains such as H9N2 and H5N1. Collectively, our data demonstrate that amiRNAs targeting the conserved regions of influenza A virus delivered by Ad vectors should be pursued as a novel strategy for prophylaxis of IV infection in humans and animals.

Abstract
Gastric cardiac adenocarcinoma (GCA) is one of common malignant tumors in the world. Multiple genes that play critical roles in inflammatory pathways probably are associated with GCA risk. We conducted a hospital-based case-control study to evaluate the genetic effects of functional single nucleotide polymorphisms (SNPs): interleukin 9 (IL9) rs31563 C > T, IL9 rs31564 G > T, IL10 rs1800872 T > G, IL12A rs2243115 T > G, IL12B rs3212227 T > G, and IL13 rs1800925 C > T on the development of GCA. Two hundred and forty-three GCA cases and 476 controls were recruited. Their genotypes were determined using a custom-by-design 48-Plex SNPscan kit. IL12B rs3212227 T > G polymorphism was associated with the increased risk of GCA. However, there was no significant association between the other five SNPs and GCA risk. Stratified analyses indicated that the risk of GCA associated with the IL12B rs3212227 T > G polymorphism was evident among female patients and patients who never smoked or consumed alcoholic drinks. These findings indicated that functional polymorphism IL12B rs3212227 T > G might correlate with GCA risk. However, our results were obtained with a limited sample size; the power of our analysis was low. Larger studies are required to confirm the current findings.

Abstract
CD45 is a transmembrane protein tyrosine phosphatase that is specifically expressed in hematopoietic cells and can initiate signal transduction via the dephosphorylation of tyrosine. Alternatively spliced transcript variants of this gene encode distinct isoforms, which indicate different functional states of CD45. Among these variants, CD45RO, which contains neither exon 4, 5, or 6, is over-expressed in lymphocytes in autoimmune diseases, including systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis, and type I diabetes. The CD45 RO serves as a marker of the immune response activity and lymphocyte development. Previous studies have indicated that exon splicing is generally correlated with local hypermethylated DNA and acetylated histone modification, while autoimmune diseases are commonly associated with global hypomethylation and histone deacetylation in lymphocytes. Thus, the question arises of how exons 4, 5, and 6 of CD45RO are excluded under the status of global DNA hypomethylation and histone deacetylation in these autoimmune diseases. On the basis of the analyses of the context sequence of CD45 and its natural antisense RNA in GenBank, we proposed that the long noncoding RNA encoded by the natural antisense gene of CD45 contributes to the expressional regulation of the CD45RO splicing variant via recruitment of DNA methyltransferase and histone modification modulators specific to the sense gene CD45; thus, it is associated with the over-expression of CD45RO and the functional regulation of lymphocytes in the pathogenic development of autoimmune diseases.

Abstract
BACKGROUND Hyperglycemia is known to induce dysrhythmias in the stomach; however, it is unknown whether they are also induced in the small intestine. Autonomic dysfunction is commonly noted in diabetes but the role it plays in hyperglycemia-induced dysrhythmias remains unknown. This study aimed to explore the effects of hyperglycemia on intestinal myoelectrical activity and the role of autonomic functions in hyperglycemia. METHODS Small intestinal myoelectrical activity (slow wave and spike activity) and autonomic functions (assessed by the spectral analysis of heart rate variability) were measured in Goto-Kakizaki diabetic rats and control rats treated with acute glucagon. Blood glucose was measured and its correlation with intestinal slow waves was determined. KEY RESULTS (1) The diabetic rats showed reduced regularity in intestinal slow waves in fasting and fed states (p < 0.001 for both), and increased sympathovagal balance (p < 0.05) in comparison with the control rats. The regularity in intestinal slow waves was negatively correlated with the HbA1c level in all rats (r = -0.663, p = 0.000). (2) Glucagon injection in the control rats induced transient hyperglycemia, intestinal slow wave dysrhythmias and impaired autonomic functions, similar to those observed in the diabetic rats. The increase in blood glucose was correlated with the decrease in the regularity of intestinal slow waves (r = -0.739, p = 0.015). CONCLUSIONS & INFERENCES Both spontaneous and glucagon-induced hyperglycemia results in slow wave dysrhythmias in the small intestine. Impairment in autonomic functions (increased sympathovagal balance) may play a role in hyperglycemia-induced dysrhythmias.

Abstract
Glioblastomas (GBMs) maintain their cellular heterogeneity with glioma stem cells (GSCs) producing a variety of tumor cell types. Here we interrogated the oncogenic roles of Lim domain only 2 (LMO2) in GBM and GSCs in mice and human. High expression of LMO2 was found in human patient-derived GSCs compared with the differentiated progeny cells. LMO2 is required for GSC proliferation both in vitro and in vivo, as shRNA-mediated LMO2 silencing attenuated tumor growth derived from human GSCs. Further, LMO2 is sufficient to induce stem cell characteristics (stemness) in mouse premalignant astrocytes, as forced LMO2 expression facilitated in vitro and in vivo growth of astrocytes derived from Ink4a/Arf null mice and acquisition of GSC phenotypes. A subset of mouse and human GSCs converted into vascular endothelial-like tumor cells both in vitro and in vivo, which phenotype was attenuated by LMO2 silencing and promoted by LMO2 overexpression. Mechanistically, the action of LMO2 for induction of glioma stemness is mediated by transcriptional regulation of Jagged1 resulting in activation of the Notch pathway, whereas LMO2 directly occupies the promoter regions of the VE-cadherin gene for a gain of endothelial cellular phenotype. Subsequently, selective ablation of human GSC-derived VE-cadherin-expressing cells attenuated vascular formation in mouse intracranial tumors, thereby significantly prolonging mouse survival. Clinically, LMO2 expression was elevated in GBM tissues and inversely correlated with prognosis of GBM patients. Taken together, our findings describe novel dual roles of LMO2 to induce tumorigenesis and angiogenesis, and provide potential therapeutic targets in GBMs.

Abstract
BACKGROUND Dysphagia is not uncommon after stroke. Dysphagia may delay the functional recovery and substantially affects the quality of life after stroke, mainly if lest untreated. To detect and treat dysphagia as early as possible is critical for patients' recovery after stroke. Electrical stimulation has been reported as a treatment for pharyngeal dysphagia in recent studies, but the therapeutic effects of neuromuscular electrical stimulation (VitalStim®) therapy lacks convincing supporting evidence, needs further clinical investigation. AIM To investigate the effects of neuromuscular electrical stimulation (VitalStim®) and traditional swallowing therapy on recovery of swallowing difficulties after stroke. DESIGN Randomized controlled trial. SETTING University hospital. POPULATION 135 stroke patients who had a diagnosis of dysphagia at the age between 50-80. METHODS 135 subjects were randomly divided into three groups: traditional swallowing therapy (N. = 45), VitalStim® therapy (N. = 45), and VitalStim® therapy plus traditional swallowing therapy (N. = 45). The traditional swallowing therapy included basic training and direct food intake training. Electrical stimulation was applied by an occupational therapist, using a modified hand-held battery-powered electrical stimulator (VitalStim® Dual Channel Unit and electrodes, Chattanooga Group, Hixson, TN, USA). Surface electromyography (sEMG), the Standardized Swallowing Assessment (SSA), Videofluoroscopic Swallowing Study (VFSS) and visual analog scale (VAS) were used to assess swallowing function before and 4 weeks after the treatment. RESULTS The study included 118 subjects with dysphagia, 40 in the traditional swallowing therapy group and VitalStim® therapy group, 38 in the VitalStim and traditional swallowing therapy group. There were significant differences in sEMG value, SSA and VFSS scores in each group after the treatment (P < 0.001). After 4-week treatment, sEMG value (917.1 ± 91.2), SSA value (21.8 ± 3.5), oral transit time (0.4 ± 0.1) and pharyngeal transit time (0.8 ± 0.1) were significantly improved in the VitalStim® and traditional swallowing therapy group than the other two groups (P < 0.001). CONCLUSION Data suggest that VitalStim® therapy coupled with traditional swallowing therapy may be beneficial for post-stroke dysphagia. CLINICAL REHABILITATION IMPACT VitalStim® therapy coupled with traditional swallowing therapy can improve functional recovery for post-stroke dysphagia.

Abstract
It is well known that gastric barrier is very important for protecting host from various insults. Simultaneously, autophagy serving as a prominent cytoprotective and survival pathway under oxidative stress conditions is being increasingly recognized. Thus, this study was conducted for investigating the effect of pyrrolidine dithiocarbamate (PDTC) on gastric barrier function and autophagy under oxidative stress induced by intragastric administration of hydrogen peroxide (H2O2). The gastric tight junction proteins [zonula occludens-1 (ZO1), occludin, and claudin1], autophagic proteins [microtubule-associated protein light chain 3I(LC3I), LC3II, and beclin1], and nuclear factor kappa B (NF-κB) signaling pathway (p65 and IκB kinase α/β) were determined by Western blot. The results showed that H2O2 exposure disturbed gastric barrier function with decreased expression of ZO1, occludin, and claudin1, and reduced gastric autophagy with decreased conversion of LC3I into LC3II in mice. However, treatment with PDTC restored these adverse effects evidenced by increased expression of ZO1 and claudin1 and increased conversion of LC3I into LC3II. Meanwhile, H2O2 exposure decreased normal human gastric epithelial mucosa cell line (GES-1) viability in a concentration-dependent way. However, after being exposed to H2O2, GES-1 exhibited autophagic response which was inconsistent with our in vivo results in mice, while PDTC failed to decrease autophagy in GES-1 induced by H2O2. Simultaneously, the beneficial effect of PDTC on gastric damage and autophagy in mice might be independent of inhibition of NF-κB. In conclusion, PDTC treatment restores gastric damages and reduced autophagy induced by H2O2. Therefore, PDTC may serve as a potential adjuvant therapy for gastric damages.

Abstract
PURPOSE It has been well established that high serum levels of interleukin-8 (IL-8) in ovarian cancer result in a poor clinical outcome. Thus, the aim of this study was investigating the role of IL-8 in ovarian cancer development. METHODS Two human ovarian cancer cell lines (SKOV3 and OVCAR3) were cocultured with IL-8 (100 ng/L) for 24 h, then cell migration was determined by transwell assay. Epithelial-mesenchymal transition (EMT)-associated proteins including E-cadherin and β-catenin, and phosphorylation status of β-catenin were investigated by Western blot analysis. RESULTS After treatment with IL-8 (100 ng/L) for 24 h, transwell assay result showed that the number of migrated ovarian cells increased significantly. Western blot analysis revealed that protein levels of E-cadherin were decreased, while that of β-catenin were elevated both in IL-8 pretreated SKOV3 and OVCAR3 cells. We further found that phosphorylation status of β-catenin were elevated either in cytoplasm or in nucleus of these two ovarian cancer cell lines after treatment with IL-8 for 24 h. CONCLUSIONS Our data suggest that IL-8 induces EMT in ovarian cancer cells and implicates its potential role in enhancing ovarian cancer cell metastasis.

Abstract
BACKGROUND The efficacy and safety of sublingual immunotherapy in house dust mite-induced asthma have yet to be firmly established. We report the results of a double-blind, placebo-controlled, randomized clinical trial performed in mainland China. METHODS After a three-month baseline period, 484 asthmatic adults were randomized 2 : 1 to 12 months of daily treatment with either an aqueous, standardized, 300 index of reactivity mixture of Dermatophagoides pteronyssinus and Dermatophagoides farinae extracts or a placebo. The primary efficacy criterion was well-controlled asthma for at least 16 of the last 20 weeks of treatment. RESULTS In the active (n = 308) and placebo (n = 157) groups, well-controlled asthma was achieved by 85.4% and 81.5% of the patients, respectively (P = 0.244). A subsequent post hoc analysis by asthma severity revealed significant clinical benefits in actively treated subjects with moderate, persistent asthma at baseline [401-800 μg budesonide/day (n = 175)], with greater achievement of well-controlled asthma (80.5% and 66.1% for the active treatment and placebo groups, respectively; P = 0.021) and totally controlled asthma (54.0% and 33.9%, respectively, P = 0.008), a higher percentage of patients with an asthma control questionnaire score < 0.75 (56.6% and 40.0%, respectively; P = 0.039) and a greater mean reduction in inhaled corticosteroid use (218.5 μg and 126.2 μg, respectively; P = 0.004). The active vs placebo differences in disease control and corticosteroid use were not significant for mild, persistent asthma. No treatment-related serious adverse events were reported. CONCLUSIONS Sublingual mite allergen immunotherapy was well tolerated in adult asthmatics and effectively controlled disease in patients with moderate (but not mild) persistent asthma (ClinicalTrials.gov: NCT00660452).

Abstract
BACKGROUND In a Spanish Lung Cancer Group (SLCG) phase II trial, the combination of BRCA1 and receptor-associated protein 80 (RAP80) expression was significantly associated with outcome in Caucasian patients with nonsmall-cell lung cancer (NSCLC). The SLCG therefore undertook an industry-independent collaborative randomized phase III trial comparing nonselected cisplatin-based chemotherapy with therapy customized according to BRCA1/RAP80 expression. An analogous randomized phase II trial was carried out in China under the auspices of the SLCG to evaluate the effect of BRCA1/RAP80 expression in Asian patients. PATIENTS AND METHODS Eligibility criteria included stage IIIB-IV NSCLC and sufficient tumor specimen for molecular analysis. Randomization to the control or experimental arm was 1 : 1 in the SLCG trial and 1 : 3 in the Chinese trial. In both trials, patients in the control arm received docetaxel/cisplatin; in the experimental arm, patients with low RAP80 expression received gemcitabine/cisplatin, those with intermediate/high RAP80 expression and low/intermediate BRCA1 expression received docetaxel/cisplatin, and those with intermediate/high RAP80 expression and high BRCA1 expression received docetaxel alone. The primary end point was progression-free survival (PFS). RESULTS Two hundred and seventy-nine patients in the SLCG trial and 124 in the Chinese trial were assessable for PFS. PFS in the control and experimental arms in the SLCG trial was 5.49 and 4.38 months, respectively [log rank P = 0.07; hazard ratio (HR) 1.28; P = 0.03]. In the Chinese trial, PFS was 4.74 and 3.78 months, respectively (log rank P = 0.82; HR 0.95; P = 0.82). CONCLUSION Accrual was prematurely closed on the SLCG trial due to the absence of clinical benefit in the experimental over the control arm. However, the BREC studies provide proof of concept that an international, nonindustry, biomarker-directed trial is feasible. Thanks to the groundwork laid by these studies, we expect that ongoing further research on alternative biomarkers to elucidate DNA repair mechanisms will help define novel therapeutic approaches. TRIAL REGISTRATION NCT00617656/GECP-BREC and ChiCTR-TRC-12001860/BREC-CHINA.

Abstract
UNLABELLED We found that type 2 diabetes mellitus (T2DM) was associated with increased fracture risks in non-obese postmenopausal Chinese women, and suppressed bone turnover might be the underlying mechanism. This is the first study evaluating and explaining the association of T2DM with osteoporotic fracture in Chinese population with such high homogeneity. INTRODUCTION The aim of this study was to investigate the association of T2DM with osteoporotic fracture in postmenopausal Chinese women. METHODS One thousand four hundred ten postmenopausal women were included and stratified into non-obese population [body mass index (BMI) < 25 kg/m(2)] and obese population (BMI ≥ 25 kg/m(2)). Each type of population was classified into diabetes group, impaired fasting glucose (IFG) group, and normal glucose group. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Serum C-terminal telopeptide of type I collagen (β-CTX) and serum N-amino terminal prepeptide of type 1 procollagen (P1NP) were quantified. Vertebral fractures (VFs) and non-VFs were assessed by vertebral X-ray and questionnaire, respectively. RESULTS Comparing to normal glucose group, diabetes group and IFG group both had lower levels of P1NP and β-CTX, despite population types. Despite having non-decreased BMD, non-obese diabetic patients had higher risks of total fracture and VF than BMI-matched normal glucose subjects (both P < 0.05). Non-obese population was further classified by a mean value of P1NP or β-CTX. Non-obese diabetic patients with low P1NP or high β-CTX had higher fracture risks (both P < 0.05), comparing to non-obese normal glucose subjects with high P1NP or high β-CTX, respectively. CONCLUSIONS Type 2 diabetic patients had suppressed bone turnover, which might explain the increased fracture risks, independent of BMD. IFG patients might also have poor bone quality and need early prevention.

Abstract
Although many studies have shown that transposable element (TE) activation is induced by hybridisation and polyploidisation in plants, much less is known on how different types of TE respond to hybridisation, and the impact of TE-associated sequences on gene function. We investigated the frequency and regularity of putative transposon activation for different types of TE, and determined the impact of TE-associated sequence variation on the genome during allopolyploidisation. We designed different types of TE primers and adopted the Inter-Retrotransposon Amplified Polymorphism (IRAP) method to detect variation in TE-associated sequences during the process of allopolyploidisation between Brassica rapa (AA) and Brassica oleracea (CC), and in successive generations of self-pollinated progeny. In addition, fragments with TE insertions were used to perform Blast2GO analysis to characterise the putative functions of the fragments with TE insertions. Ninety-two primers amplifying 548 loci were used to detect variation in sequences associated with four different orders of TE sequences. TEs could be classed in ascending frequency into LTR-REs, TIRs, LINEs, SINEs and unknown TEs. The frequency of novel variation (putative activation) detected for the four orders of TEs was highest from the F1 to F2 generations, and lowest from the F2 to F3 generations. Functional annotation of sequences with TE insertions showed that genes with TE insertions were mainly involved in metabolic processes and binding, and preferentially functioned in organelles. TE variation in our study severely disturbed the genetic compositions of the different generations, resulting in inconsistencies in genetic clustering. Different types of TE showed different patterns of variation during the process of allopolyploidisation.

Abstract
The scarab beetle Holotrichia oblita Faldermann (Coleoptera: Scarabaeidae) is a predominant underground pest in the northern parts of China, and its larvae (grubs) cause great economic losses because of its wide range of host plants and covert habitats. Environmentally friendly strategies for controlling adults would have novel and broad potential applications. One potential pest management measure is the regulation of olfactory chemoreception to control target insect pests. In the process of olfactory recognition, odorant-binding proteins (OBPs) are believed to carry hydrophobic odorants from the environment to the surface of olfactory receptor neurons. To obtain a better understanding of the relationship between OBP structures and their ligands, homology modelling and molecular docking have been conducted on the interaction between HoblOBP1 and hexyl benzoate in the present study. Based on the results, site-directed mutagenesis and binding experiments were combined to describe the binding sites of HoblOBP1 and to explore its ligand-binding mechanism. After homology modelling of HoblOBP1, it was found that the three-dimensional structure of HoblOBP1 consists of six α-helices and three disulphide bridges that connect the helices, and the hydrophobic pockets are both composed of five helices. Based on the docking study, we found that van der Waals interactions and hydrophobic interactions are both important in the bonding between HoblOBP1 and hexyl benzoate. Intramolecular residues formed the hydrogen bonds in the C terminus of the protein and the bonds are crucial for the ligand-binding specificity. Finally, MET48, ILE80 and TYR111 are binding sites predicted for HoblOBP1. Using site-directed mutagenesis and fluorescence assays, it was found that ligands could not be recognized by mutant of Tyr111. A possible explanation is that the compound could not be recognized by the mutant, and remains in the binding cavity because of the loss of the intramolecular hydrogen bonding that acts as a holder. So we believe that Tyr111 of HoblOBP1 is a key binding site. We also believe that Ile80A is a very important binding site, especially to some ligands.

Abstract
BACKGROUND Pollen food syndrome is one of the main causes of food allergies in adults. However, the intrinsic immunological mechanisms remain unclear. METHODS Forty pollinosis sufferers [23 with a food allergy (PSFA) and 17 without a food allergy (PS)] and 17 non-atopic healthy controls were included in this study. The PSFA group was subdivided into an oral allergy syndrome group, a systemic reaction group, and an anaphylactic reaction group according to their symptoms after eating the suspected foods. Serum IL-10 and TGF-β levels of all participants were determined by ELISA. Clinical characteristics of the patients were also evaluated. RESULTS There were no significant differences in age, sex, pollen-associated symptoms, duration of respiratory disease, and positive parental history of atopy between the PSFA and PS groups. Compared to healthy controls, serum IL-10 levels of both the PSFA group and PS group were significantly lower (p≤0.01), but TGF β levels were significantly higher in the PSFA group (35.3±5.6ng/ml vs. 31.2±6.6ng/ml, respectively; p=0.037). Within the PSFA group, IL-10 levels in the anaphylactic reaction subgroup were significantly lower compared to oral allergy syndrome subgroup (1.87±0.47pg/ml vs. 1.40±0.30pg/ml, respectively; p=0.027). More severe food allergy symptoms were associated with lower serum IL-10 levels. In contrast, the highest serum levels of TGF-β were found in patients from the anaphylactic reaction subgroup. CONCLUSIONS With the exception of a defect in regulatory cells represented by the reduction of IL-10, other potential immunological mechanisms (e.g., Th17 or IL-23 together with TGF-β) may be involved in the development of pollen food syndrome.

Abstract
SETTING Two projects were introduced in October 2007 to improve treatment completion among rural-to-urban migrant tuberculosis (TB) patients in Shanghai. The Communicable Disease Research Consortium (COMDIS) project provided financial incentives to poor patients, whereas the Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund) project provided incentives to all patients and increased staff time. OBJECTIVE To assess the incremental cost-effectiveness of these two projects. METHODS Case study. Costs were assessed from a societal perspective. The primary measure of effectiveness was the treatment completion rate. The incremental cost-effectiveness ratio was calculated as the additional cost of the intervention divided by the additional percentage of patients completing treatment compared to controls. RESULTS Post intervention, the treatment completion rates in the COMDIS and Global Fund projects were respectively 89% and 88%, 17% and 16% higher than in the control district (76%). For one additional per cent of patients to complete treatment, the additional cost of the COMDIS intervention was US$1891, 91% lower than that of the Global Fund intervention (US$21,904). CONCLUSION The intervention that addressed the financial barriers of poor patients was more cost-effective than the comprehensive intervention that provided assistance to both patients and providers. Further study is needed to understand the process of interventions prior to wider scale-up.
