Abstract
This study evaluated the effect of muscle satellite cells (MSCs) overexpressing myogenin (MyoG) on denervated muscle atrophy. Rat MSCs were isolated and transfected with the MyoG-EGFP plasmid vector GV143. MyoG-transfected MSCs (MTMs) were transplanted into rat gastrocnemius muscles at 1 week after surgical denervation. Controls included injections of untransfected MSCs or the vehicle only. Muscles were harvested and analyzed at 2, 4, and 24 weeks post-transplantation. Immunofluorescence confirmed MyoG overexpression in MTMs. The muscle wet weight ratio was significantly reduced at 2 weeks after MTM injection (67.17±6.79) compared with muscles injected with MSCs (58.83±5.31) or the vehicle (53.00±7.67; t=2.37, P=0.04 and t=3.39, P=0.007, respectively). The muscle fiber cross-sectional area was also larger at 2 weeks after MTM injection (2.63×10³±0.39×10³) compared with MSC injection (1.99×10³±0.58×10³) or the vehicle only (1.57×10³±0.47×10³; t=2.24, P=0.049 and t=4.22, P=0.002, respectively). At 4 and 24 weeks post-injection, the muscle mass and fiber cross-sectional area were similar across all three experimental groups. Immunohistochemistry showed that the MTM group had larger MyoG-positive fibers. The MTM group (3.18±1.13) also had higher expression of MyoG mRNA than other groups (1.41±0.65 and 1.03±0.19) at 2 weeks after injection (t=2.72, P=0.04). Transplanted MTMs delayed short-term atrophy of denervated muscles. This approach can be optimized as a novel stand-alone therapy or as a bridge to surgical re-innervation of damaged muscles.

Abstract
UNLABELLED Little attention has been paid to dermal absorption of phthalates even though modeling suggests that this pathway may contribute meaningfully to total uptake. We have concurrently collected handwipe and urine samples from 39 Beijing children (5-9 years) for the purpose of measuring levels of five phthalates in handwipes, corresponding concentrations of eight of their metabolites in urine, and to subsequently assess the contribution of dermal absorption to total uptake. In summer sampling, DEHP was the most abundant phthalate in handwipes (median: 1130 μg/m(2) ), while MnBP was the most abundant metabolite in urine (median: 232 ng/ml). We found significant associations between the parent phthalate in handwipes and its monoester metabolite in urine for DiBP (r = 0.41, P = 0.01), DnBP (r = 0.50, P = 0.002), BBzP (r = 0.48, P = 0.003), and DEHP (r = 0.36, P = 0.03). Assuming that no dermal uptake occurred under clothing-covered skin, we estimate that dermal absorption of DiBP, DnBP, BBzP, and DEHP contributed 6.9%, 4.6%, 6.9%, and 3.3%, respectively, to total uptake. Assuming that somewhat attenuated dermal uptake occurred under clothing-covered skin, these estimates increase to 19%, 14%, 17%, and 10%. The results indicate that absorption from skin surfaces makes a meaningful contribution to total phthalate uptake for children and should be considered in future risk assessments. PRACTICAL IMPLICATIONS This study indicates that children’s hands acquire substantial amounts of various phthalates. The levels measured in handwipes, although higher, are somewhat representative of levels on other body locations. Via dermal absorption, as well as hand-to-mouth activity, phthalates on hands and other body locations contribute to the overall body burden of these compounds. Dermal absorption from air and contact transfer from surfaces is expected to occur for many SVOCs commonly found indoors (e.g. bisphenols, synthetic musks, organophosphates). However, the dermal pathway has often been neglected in exposure assessments of indoor pollutants. Knowledge regarding phthalates and other SVOCs in handwipes can facilitate our understanding of risks and aid in the mitigation of adverse health effects resulting from indoor exposures. To make progress toward these goals, further studies are necessary, including investigations of phthalate level variability in skinwipes collected at different locations on the body and the impact of clothing on dermal absorption from air.

Abstract
Peripheral blood monocytes (PBMs) are an important source of precursors of osteoclasts, the bone-resorbing cells and the cytokines produced by PBMs that have profound effects on osteoclast differentiation, activation, and apoptosis. So PBMs represent a highly valuable and unique working cell model for bone-related study. Finding an appropriate working cell model for clinical and (epi-)genomic studies of human skeletal disorders is a challenge. Peripheral blood monocytes (PBMs) can give rise to osteoclasts, the bone-resorbing cells. Particularly, PBMs provide the sole source of osteoclast precursors for adult peripheral skeleton where the bone marrow is normally hematopoietically inactive. PBMs can secrete potent pro- and anti-inflammatory cytokines, which are important for osteoclast differentiation, activation, and apoptosis. Reduced production of PBM cytokines represents a major mechanism for the inhibitory effects of sex hormones on osteoclastogenesis and bone resorption. Abnormalities in PBMs have been linked to various skeletal disorders/traits, strongly supporting for the biological relevance of PBMs with bone metabolism and disorders. Here, we briefly review the origin and further differentiation of PBMs. In particular, we discuss the close relationship between PBMs and osteoclasts, and highlight the utility of PBMs in study the pathophysiological mechanisms underlying various skeletal disorders.

Abstract
Internal transcribed spacer 1 (ITS1) sequences from wild-type Exopalaemon carinicauda (N = 124) from the East China Sea were amplified and sequenced. Sequences were polymorphic and ranged from 388 to 583 bp in length. The average content of GC in sequences was significantly higher than that of AT. Altogether, 604 mutant sites with 123 haplotypes were detected; 46.7% were polymorphic sites. The genetic diversity index of population Y was highest, and the lowest was population X. Eight microsatellite sequences were detected; the most-repeated sequences were (GA)n, (AG)n, (GT)n, (TG)n, (TC)n, and (CT)n. Analysis of molecular variance revealed that genetic differentiation among the four populations were very weak, or modest. A molecular evolutionary tree was constructed using the neighbor-joining method and MEGA 6.0, and the phyletic evolutionary relationships among several Palaemonidae species examined. The phylogenetic tree showed that individuals of the same species, as well as the species of the same genus, clustered together, consistent with morphological classifications.

Abstract
The role of microRNAs (miRNAs) in the regulation of mammalian reproduction has been demonstrated previously. However, only a few studies have assessed the role of miRNAs in the reproduction processes of sheep. The elucidation of miRNA expression profiles in the ovaries of different sheep breeds representing fecundity extremes will be useful in understanding the roles of miRNAs in sheep reproduction. In this study, two small RNA libraries were constructed from ovary tissue taken from Qira black sheep and Hetian sheep during the estrous period and then sequenced using the Solexa sequencing method. We obtained 9,565,212 and 9,563,426 high-quality reads from Qira black sheep and Hetian sheep, respectively. In total, 531 miRNAs, including 98 putative miRNAs, were identified. Among the conserved miRNAs, 125 known miRNAs were significantly differentially expressed in the Qira black sheep and Hetian sheep libraries, with 24 upregulated and 101 downregulated in the Hetian sheep compared to the Qira black sheep. Four differentially expressed miRNAs were analyzed using real-time quantitative PCR to validate the reliability of the Solexa sequencing results. These results provide a foundation for future research on the regulation of miRNAs in sheep fertility and enrich the sheep miRNA databases.

Abstract
Current standard of care for muscle-invasive urothelial cell carcinoma (UCC) is surgery along with perioperative platinum-based chemotherapy. UCC is sensitive to cisplatin-based regimens, but acquired resistance eventually occurs, and a subset of tumors is intrinsically resistant. Thus, there is an unmet need for new therapeutic approaches to target chemotherapy-resistant UCC. Yes-associated protein (YAP) is a transcriptional co-activator that has been associated with bladder cancer progression and cisplatin resistance in ovarian cancer. In contrast, YAP has been shown to induce DNA damage associated apoptosis in non-small cell lung carcinoma. However, no data have been reported on the YAP role in UCC chemo-resistance. Thus, we have investigated the potential dichotomous role of YAP in UCC response to chemotherapy utilizing two patient-derived xenograft models recently established. Constitutive expression and activation of YAP inversely correlated with in vitro and in vivo cisplatin sensitivity. YAP overexpression protected while YAP knock-down sensitized UCC cells to chemotherapy and radiation effects via increased accumulation of DNA damage and apoptosis. Furthermore, pharmacological YAP inhibition with verteporfin inhibited tumor cell proliferation and restored sensitivity to cisplatin. In addition, nuclear YAP expression was associated with poor outcome in UCC patients who received perioperative chemotherapy. In conclusion, these results suggest that YAP activation exerts a protective role and represents a pharmacological target to enhance the anti-tumor effects of DNA damaging modalities in the treatment of UCC.

Abstract
This study aims to observe the differentiation effects of transforming growth factor β1 (TGF-β1)-transfected bone marrow mesenchymal stem cells (BMMSCs) into the nucleus pulposus-like cells under simulated microgravity conditions. BMMSCs were isolated from the adult rabbits, then cultured and proliferated to the third generation. After transfected by TGF-β1, these MMSCs were incubated in the calcium alginate gel microspheres and rotary cell culture system. The content changes of TGF-β1 inside BMMSCs, as well as the proliferation abilities of BMMSCs, were detected. The immunohistochemistry and toluidine blue staining were performed to detect the type II collagen. The RT-PCR method was performed to detect the expressions of proteoglycan and type II collagen mRNA. Results found that, on the 14th day, the polygonal nucleus pulposus-like cells could be observed. The TGF-β1 content inside the supernatant and the DNA content inside BMMSCs were significantly increased (P<0.05). The immunohistochemistry staining exhibited the positive results about the type II collagen. RT-PCR showed the expressions of proteoglycan and type II collagen mRNA inside BMMSCs. The TGF-β1-transfected BMSCs exhibited the increased synthesizing abilities of proteoglycan and type II collagen under simulated microgravity conditions than the control group.

Abstract
Numerous resting-state fMRI studies have demonstrated altered functional connectivity within canonical intrinsic connectivity networks (ICNs) in patients with idiopathic generalized epilepsy (IGE). It is possible that the widespread ICN abnormalities on electroencephalography in IGE derive from abnormal functional interactions between ICNs. To test this possibility, we explored the functional connectivity between the subnetworks of the default mode network (DMN), attention network (ATN), and frontoparietal control network (FPN) using independent component analysis of resting-state fMRI data collected from 27 patients with IGE characterized by generalized tonic-clonic seizures (GTCS) and 29 matched healthy controls. It was observed that the left FPN exhibited increased connectivity with the anterior DMN and ventral ATN, while the right FPN exhibited increased connectivity with the anterior and posterior DMNs in the patients with IGE-GTCS. Furthermore, the functional connectivity between the anterior DMN and ventral ATN was negative in healthy controls but positive in the patients with IGE-GTCS. In addition, the anterior DMN exhibited increased intranetwork functional connectivity in the right frontal pole in IGE-GTCS. These findings suggest that IGE-GTCS is likely associated with a disrupted brain organization probably derived from abnormal functional interactions among ICNs. Furthermore, the alterations in the functional architecture of the ICNs may be related to deficits in mentation and attention in IGE-GTCS, providing informative evidence for the understanding of the pathophysiology of IGE-GTCS.

Abstract
Platinum-induced myelosuppression severely impedes successful chemotherapy in non-small-cell lung cancer (NSCLC) patients. Hence, it is clinically important to identify the patients who are at high risk for severe toxicity to certain chemotherapy. We first carried out a genome-wide scan of 906 703 single-nucleotide polymorphisms (SNPs) to identify genetic variants associated with platinum-induced myelosuppression risk in 333 NSCLC patients with chemotherapy. Then, we replicated 24 SNPs that had P<1 × 10(-4) in another independent cohort of 876 NSCLC patients. With P<0.05 as the criterion of statistical significance, we found that rs13014982 at 2q24.3 and rs9909179 at 17p12 exhibited consistently significant associations with myelosuppression risk in both the genome-wide association studies (GWAS) scan and the replication stage (rs13014982: odds ratio (OR)=0.55, 95% confidence intervals (CIs): 0.41-0.74, P=7.29 × 10(-5) for GWAS scan and OR=0.77, 95% CI: 0.65-0.93, P=0.006 for replication stage; rs9909179: OR=0.51, 95% CI: 0.37-0.70, P=4.60 × 10(-5) for GWAS scan and OR=0.82, 95% CI: 0.68-0.99, P=0.040 for replication stage; both in additive model). In combined samples of genome-wide scan and replication samples, the minor alleles of rs13014982 and rs9909179 remained significant associations with the decreased risk of myelosuppression (rs13014982: OR=0.71, 95% CI: 0.61-0.83, P =1.36 × 10(-5); rs9909179: OR=0.76, 95% CI: 0.65-0.89, P=0.001). Rs13014982 at 2q24.3 and rs9909179 at 17p12 might be independent susceptibility markers for platinum-induced myelosuppression risk in NSCLC patients.

Abstract
We describe a case of primary cutaneous mucormycosis in a 44-year-old man with an 18-month history of infiltrative erythematous plaques and haemorrhagic crusting on the dorsum of his left hand. The isolate was identified as Mucor irregularis (formerly Rhizomucor variabilis) based on the fungus morphology and DNA sequencing results. Improvement was observed after a 6-month treatment course of itraconazole. No recrudescence was seen during a follow-up of 23 months after treatment.

Abstract
OBJECTIVES To analyse the concentration of interleukin (IL)-27 and IL-23 in serum and urine of patients with systemic lupus erythematosus (SLE) compared with healthy controls (HC). METHOD An enzyme-linked immunosorbent assay (ELISA) was used to analyse the serum and urine concentration of IL-27 and IL-23 from 50 patients with lupus nephritis (LN), 55 patients without LN, and 30 HC. The correlations between the levels of IL-27, IL-23, and disease activity, clinical parameters in SLE patients were analysed. RESULTS The levels of IL-27 and IL-23 increased significantly in the serum and urine of SLE patients with and without LN compared with HC. Moreover, urine levels of IL-27 and IL-23 were correlated with the renal SLE Disease Activity Index (rSLEDAI) score and 24-h urinary protein levels. After 6 months of immunosuppressive treatment, urine IL-27 expression rose significantly in SLE patients with LN. CONCLUSIONS IL-27 and IL-23 may be involved in the pathogenesis of LN.

Abstract
PURPOSE OF INVESTIGATION To compare the therapeutic and side effects of using Californium252 (252Cf) neutron brachytherapy with neoadjuvant intra-arterial embolism chemotherapy in combination with surgery for treating Stage Ib2-IIb cervical cancers (CCs). MATERIALS AND METHODS Thirty-two Stage Ib2-IIb CC patients were enrolled and randomly divided into two groups from January 2007 to April 2010 in the present Hospital. Prior to surgery within four weeks, a total of 17 cases were treated with 252Cf neutron brachytherapy (700-800 cGy doses at point A) once a week (Group A), and 15 cases were treated by neoadjuvant intra-arterial embolism chemotherapy using a combination of bleomycin, carboplatin, and cyclophosphamide twice (Group B). The clinical symptoms and signs, side effects, and relapse condition follow up until July 2013 were compared between the two groups for the perioperation. RESULTS Reductions in tumor mass and CR+PR were not significantly different between the groups before the surgery (p > 0.05). Abdominal pain and pelvic adhesions were significantly more severe in Group B (p < 0.05). There were no significant differences in surgical time, blood loss or the other side effects between Groups A and B (p > 0.05). The percentage of pelvic tumor recurrences in Group A was lower than that of the patients in Group B (11.8% vs 20.0%) although with no significant difference at present. No distant metastasis has been found in both two groups. CONCLUSION Except for less abdominal pain and pelvic adhesions, 252Cf neutron brachytherapy has perioperative effects similar to those of neoadjuvant intra-arterial embolism chemotherapy.

Abstract
Tubular atrophy and dysfunction is a critical process underlying diabetic nephropathy (DN). Understanding the mechanisms underlying renal tubular epithelial cell survival is important for the prevention of kidney failure associated with glucotoxicity. Autophagy is a cellular pathway involved in protein and organelle degradation. It is associated with many types of cellular homeostasis and human diseases. To date, little is known of the association between high concentrations of glucose and autophagy in renal tubular cells. In the present study, we investigated high glucose-induced toxicity in renal tubular epithelial cells by means of several complementary assays, including cell viability, cell death assays and changes in ultrastructure in an immortalized human kidney cell line, HK-2 cells. The extent of apoptosis was significantly increased in the HK-2 cells following treatment with high levels of glucose. In addition, in in vivo experiments using diabetic rats, high glucose exerted harmful effects on the tissue structure of the kidneys in the diabetic rats. Chronic exposure of the HK-2 cells and tubular epithelial cells of nephritic rats to high levels of glucose induced autophagy. Liraglutide inhibited these effects; however, treatment witht a glucagon-like peptide-1 receptor (GLP-1R) antagonist enhanced these effects. Our results also indicated that the exposure of the renal tubular epithelial cells to high glucose concentrations in vitro led to the downregulation of GLP-1R expression. Liraglutide reversed this effect, while the GLP-1R antagonist promoted it, promoting autophagy, suggesting that liraglutide exerts a renoprotective effect in the presence of high glucose, at least in part, by inhibiting autophagy and increasing GLP-1R expression in the HK-2 cells and kidneys of diabetic rats.

Abstract
Inspired by sensing strategies observed in birds and bats, a new attitude control concept of directly using real-time pressure and shear stresses has recently been studied. It was shown that with an array of onboard airflow sensors, small unmanned aircraft systems can promptly respond to airflow changes and improve flight performances. In this paper, a mapping function is proposed to compute aerodynamic moments from the real-time pressure and shear data in a practical and computationally tractable formulation. Since many microscale airflow sensors are embedded on the small unmanned aircraft system surface, it is highly possible that certain sensors may fail. Here, an adaptive control system is developed that is robust to sensor failure as well as other numerical mismatches in calculating real-time aerodynamic moments. The advantages of the proposed method are shown in the following simulation cases: (i) feedback pressure and wall shear data from a distributed array of 45 airflow sensors; (ii) 50% failure of the symmetrically distributed airflow sensor array; and (iii) failure of all the airflow sensors on one wing. It is shown that even if 50% of the airflow sensors have failures, the aircraft is still stable and able to track the attitude commands.

Abstract
BACKGROUND Many basic mechanistic studies found that aspirin inhibited multiple pathways involved in non-alcoholic fatty liver disease (NAFLD) development. AIM To investigate an association between aspirin use and NAFLD prevalence in the general US population. METHODS We conducted a cross-sectional analysis of data from the Third National Health and Nutrition Examination Survey (NHANES III). We included 11 416 adults aged 20-74 years who underwent ultrasonography; of those, 2889 were identified as having NAFLD and 8527 as controls. Aspirin use during the month prior to interview was categorised as never use (0 times), occasional use (1-14 times) and regular use (≥15 times). RESULTS In the multivariate unconditional logistic regression analysis, regular relative to no aspirin use was inversely associated with prevalent NAFLD [odds ratio (OR) = 0.62, 95% confidence interval (CI) 0.51-0.74; P for trend = 0.04], a finding that was primarily limited to men (OR = 0.32, 95% CI 0.23-0.45; P for interaction < 0.01) and those who were older (>60 years) (OR = 0.21, 95% CI 0.14-0.30; P for interaction < 0.01). CONCLUSION These findings, from the first human study to investigate an association of aspirin use with NAFLD, suggest that regular aspirin use (≥ 15 times per month) may be associated with a lower prevalence of NAFLD, primarily among men and older patients.

Abstract
Hepatic allograft rejection remains a challenging problem, with acute rejection episode as the major barrier for long-term survival in liver transplant recipients. To explore a strategy to prevent allograft rejection, we hypothesized that mesenchymal stem cells (MSCs) genetically engineered with interleukin-10 (IL-10) could produce beneficial effects on orthotopic liver transplantation (OLT) in the experimental rat model. Syngeneic MSCs transduced with IL-10 were delivered via the right jugular vein 30 min post-orthotopic transplantation in the rat model. To evaluate liver morphology and measure cytokine concentration, the blood and liver samples from each animal group were collected at different time-points (3, 5 and 7 days) post-transplantation. The mean survival time of the rats treated with MSCs-IL-10 was shown to be much longer than those treated with saline. According to Banff scheme grading, the saline group scores increased significantly compared with those in the MSCs-IL-10 group. Retinoid acid receptor-related orphan receptor gamma t (RORγt) expression was more increased in the saline group compared to those in the MSCs-IL-10 group in a time-dependent manner; forkhead box protein 3 (FoxP3) expression also decreased significantly in the saline group compared with those in the MSCs-IL-10 group in a time-dependent manner. The expression of cytokines [IL-17, IL-23, IL-6, interferon (IFN)-γ and tumour necrosis factor (TNF)-α] in the saline groups increased significantly compared with the time-point-matched MSCs-IL-10 group, whereas cytokine expression of (IL-10, TGF-β1) was deceased markedly compared to that in the MSCs-IL-10 group. These results suggest a potential role for IL-10-engineered MSC therapy to overcome clinical liver transplantation rejection.

Abstract
We report the serological evidence of low-pathogenic avian influenza (LPAI) H9N2 infection in an occupational poultry-exposed population and a general population. A serological survey of an occupational poultry-exposed population and a general population was conducted using a haemagglutinin-inhibiting (HI) assay in Shanghai, China, from January 2008 to December 2010. Evidence of higher anti-H9 antibodies was found in serum samples collected from poultry workers. During this period, 239 H9N2 avian influenza viruses (AIVs) were isolated from 9297 tracheal and cloacal paired specimens collected from the poultry in live poultry markets. In addition, a total of 733 influenza viruses were isolated from 1569 nasal and throat swabs collected from patients with influenza-like symptoms in a sentinel hospital, which include H3N2, H1N1, pandemic H1N1 and B, but no H9N2 virus was detected. These findings highlight the need for long-term surveillance of avian influenza viruses in occupational poultry-exposed workers.

Abstract
BACKGROUND Circulating microRNAs (miRNAs) have been implicated as novel biomarkers for gastric cancer (GC) diagnosis. However, the mixture of GC subtypes may have led to the inconsistent circulating miRNA profiles, and the clinical performance of circulating miRNAs has not yet been evaluated independently on early detection of GC. METHODS A four-phase study was designed with a total of 160 cancer-free controls, 124 patients with gastric non-cardia adenocarcinoma (GNCA) and 36 patients diagnosed gastric cardia adenocarcinoma (GCA). In the discovery phase, we screened the miRNA expression profile in plasma of 40 GNCA patients (stage I) and 40 matched controls by TaqMan low density array (TLDA) chips with pooled samples. Differentially expressed miRNAs were further validated in individual sample using quantitative reverse-transcriptase PCR (qRT-PCR) in the training phase. Subsequently, in an independent validation phase, the identified miRNAs were evaluated in 48 GNCA patients (stage I) and 102 matched controls. Finally, the identified miRNAs were further assessed in an external validation phase including advanced GNCA and GCA patients. Additionally, the expression levels of identified miRNAs were measured in the media of BGC823 and MGC803 cell lines. RESULTS Five miRNAs (miR-16, miR-25, miR-92a, miR-451 and miR-486-5p) showed consistently elevated levels in plasma of the GC patients as compared with controls, and were identified to be potential markers for GNCA with area under the receiver operating characteristic (ROC) curves (AUCs) ranging from 0.850 to 0.925 and 0.694 to 0.790 in the training and validation phases, respectively. The five-miRNA panel presented a high diagnostic accuracy for the early-stage GNCA (AUCs=0.989 and 0.812 for the training and validation phases, respectively). Three miRNAs (miR-16, miR-25 and miR-92a) were excreted into the culture media of GC cell lines. CONCLUSIONS The five-miRNA panel in plasma may serve as a potential non-invasive biomarker in detecting the early-stage GC.

Abstract
MicroRNAs (miRNAs) are small RNA molecules that modulate gene expression implicated in cancer, which play crucial roles in diverse biological processes, such as development, differentiation, apoptosis, and proliferation. The aim of this study was to investigate whether miR-30c mediated the resistance of breast cancer cells to the chemotherapeutic agent doxorubicin (ADR) by targeting tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (YWHAZ). miR-30c was downregulated in the doxorubicin-resistant human breast cancer cell lines MCF-7/ADR and MDA-MB-231/ADR compared with their parental MCF-7 and MDA-MB-231 cell lines, respectively. Furthermore, we observed that transfection of an miR-30c mimic significantly suppressed the ability of MCF-7/ADR to resist doxorubicin. Moreover, the anti-apoptotic gene YWHAZ was confirmed as a target of miR-30c by luciferase reporter assay, and further studies indicated that the mechanism for miR-30c on the sensitivity of breast cancer cells involved YWHAZ and its downstream p38 mitogen-activated protein kinase (p38MAPK) pathway. Together, our findings provided evidence that miR-30c was one of the important miRNAs in doxorubicin resistance by regulating YWHAZ in the breast cancer cell line MCF-7/ADR.

Abstract
Trichostatin A (TSA) is a potent inhibitor of histone deacetylases and has been shown to improve cloned embryo pre-implantation and term development. We examined the effects of TSA treatment on cloned mouse embryonic gene expression using microarrays. Cloned mouse embryos were generated using long-term haematopoietic stem cells (LT-HSC) and terminally differentiated granulocytes (Gr-1) as nuclear donors, which have been shown to have significantly different cloning efficiencies (Sung et al. 2006 Nat. Gen. 38, 1323–1328). Late 2-cell and blastocyst stage cloned embryos and control, BDF1 in vivo and IVF embryos (n = 10 from each embryo type and stage, except LT-HSC blastocysts, where n = 5) were snap frozen in liquid nitrogen. Total RNA was isolated from individual embryos and amplified using the TargetAmp 2 round Aminoallyl aRNA amplification kit (Epicentre Biotechnologies, Madison, WI, USA). Amplified RNA from each embryo and a standard reference was labelled with Cy3 or Cy5 and hybridized to the mouse exonic evidence based oligonucleotide (MEEBO) microarray allowing for the interrogation of ~25 000 genes. After Loess normalization, ANOVA with false discovery rate (P < 0.001) was used to identify differentially expressed (DE) genes. A subset of the DE genes was verified by RT-qPCR. These two cell types drastically differed in their potential to give rise to morula/blastocyst stage embryos: LT-HSC: 4.1% v. Gr-1: 38.9%. When treated with 10 nM TSA (Sigma, St. Louis, MO, USA) for 10 h immediately after activation, the morula/blastocyst rate increased to 66.1% for the LT-HSC cloned embryos and to 69.3% for the Gr-1 cloned embryos. At the 2-cell stage, we identified 2172 DE genes between the TSA-treated and untreated LT-HSC embryos. There were 512 DE genes between the Gr-1 and Gr-1 TSA embryos. Interestingly, the cloned embryos were more similar to the in vivo and IVF embryos after TSA treatment at the 2-cell stage, as evidenced by hierarchical clustering and the reduced number of DE genes: LT-HSC v. in vivo = 2622 genes; LT-HSC TSA v. in vivo = 473; Gr-1 v. in vivo = 1448; Gr-1 TSA v. in vivo = 312. By the blastocyst stage, the effect of TSA was considerably less pronounced with 18 and 17 DE genes between the LT-HSC/TSA and Gr-1/TSA embryos, respectively. These data indicate that TSA treatment normalizes 2-cell cloned embryo gene expression, enabling significantly more embryos to develop to the blastocyst stage. Our findings demonstrate that TSA exerted the greatest effect on the LT-HSC embryos, which were the most difficult to reprogram by SCNT.

Abstract
OBJECTIVE The aim of this study was to observe clinical curative effects of combination application of dimethylbiguanide and pioglitazone and single application of pioglitazone in patients with polycystic ovarian syndrome (PCOS) complicated with insulin resistance (IR). MATERIALS AND METHODS Forty cases of patients with PCOS complicated with IR were investigated, and 20 cases of infertile women without PCOS were taken as the control group. PCOS group was divided into group A and group B according to body mass index (BMI) to detect glucose and lipids metabolism indicators, C reactive protein (CRP), etc. There were 20 cases in group A (Pioglitazone) and 20 cases in group B (dimethylbiguanide and pioglitazone). After treatment for 12 weeks, changes of the above various indicators were compared. RESULTS After treatment, insulin resistance index and serum testosterone (T) of two groups patients with PCOS significantly reduced (p < 0.05). Compared to before treatment, BMI of group B significantly reduced (p < 0.05). For INS at two hours after treatment, group B reduced more significantly (p < 0.05). CONCLUSION The combination of dimethylbiguanide and pioglitazone was more effective for the treatment of PCOS complicated with IR than simple pioglitazone; chronic inflammation occurrence was possibly one of reasons for insulin sensitivity reduction of patients with PCOS.

Abstract
Methotrexate (MTX) is an effective treatment for childhood acute lymphoblastic leukemia (ALL) or Non-Hodgkin lymphoma (NHL); however, toxicity can arise with high doses MTX (HDMTX), especially in patients with delayed MTX elimination. Routine monitoring of plasma MTX concentrations is clinically important, but unfortunately is not always feasible. The aim of this study was to examine the relationship between MTX elimination and renal function to identify parameters that may be useful for predicting delayed MTX elimination in Chinese children with ALL and NHL. A total of 105 children with ALL and NHL were included in the study. Each patient received HDMTX (3 or 5 g/m2) over 24 hours. Plasma MTX concentrations were measured at 24, 48, and 96 hours. Delayed elimination was indicated by plasma MTX concentrations ≥1.0 at 48 hours or ≥0.1 μmol/L at 96 hours. Creatinine clearance rate (CCr) and serum Cr concentrations were measured at 0, 24, and 48 hours. There were 39 patients (37.1%) with delayed MTX elimination. For patients with delayed MTX elimination, the 24 hour plasma MTX concentration was negatively correlated with the 24 hour CCr (P=0.019). The 48 hour plasma MTX concentration was positively correlated with 24 and 48 hour serum Cr concentrations (P=0.001 and P<0.001, respectively), and negatively correlated with the 24 and 48 CCr (both P<0.001). Both MTX concentrations and elimination time decreased with increasing CCr (P<0.05 and P<0.001, respectively). Receiver operating characteristic curves revealed that the best predictors of delayed MTX elimination were 24 hour CCr 36 mmol/L (sensitivity: 64.7%; specificity: 77.4%) (both P < 0.001). CCr and serum Cr concentration may be useful for monitoring plasma MTX concentrations in children receiving HDMTX for ALL and NHL and for predicting delayed MTX elimination.

Abstract
BACKGROUND Tumor necrosis might be a consequence of innate sensitivity of tumor cells to changed dosage instead of the increased dosage of chemotherapeutics in the treatment of osteosarcoma patients. AIM To explore whether dose-intensive regimen was a better treatment method than dose-control chemotherapy for high-grade osteosarcoma patients. MATERIALS AND METHODS The data of the included studies was analyzed by random-effects model when there was heterogeneity, otherwise by fixed-effects method. Meta-analysis outcomes were calculated as risk ratio (RR) and 95% confidence interval (CI) for 5-year disease free survival rate, 5-year overall survival, local recurrence rate, good histological response rate and Limb salvage rate. RESULTS Five studies involving 1434 patients with high-grade osteosarcoma were included. All the included studies were inadequate in the information about randomization and blinding method. The meta-analysis showed that there was no significant difference between the dose-intensive group and the dose control group in 5-year disease free survival rate (RR: 1.08, 95% CI: 0.96-1.21), 5-year overall survival rate (RR: 1.07, 95% CI: 0.98-1.17), good histological response rate (RR: 1.08, 95% CI: 0.82-1.43), limb salvage rate (RR: 0.97, 95% CI: 0.93-1.02). However, the local recurrence rate (RR: 0.65, 95% CI: 0.46- 0.92) and the 5-year disease free survival rate of the good and poor histological response (RR: 1.57, 95% CI: 1.36- 1.82) were significantly different. CONCLUSIONS Dose-intensive regimen might not be a preferred treatment for all of the high-grade osteosarcoma patients. Although there were advantages in dose-intensive regimen, appropriate dosage of chemotherapy should be considered in clinical cases.

Abstract
OBJECTIVE Fracture is the major clinical outcome of osteoporosis. The vitamin D receptor (VDR) gene is thought to be a candidate gene for osteoporosis. Many genetic studies have suggested an association of VDR polymorphisms and fracture risk, but evidence remains conflicting. The aim of this study was to evaluate the genetic effect of the BsmI, TaqI, ApaI and FokI polymorphisms in the VDR gene on fracture risk in postmenopausal women. METHODS Relevant studies were identified from the following electronic databases: PubMed, Embase, and Web of Science before September 2013. Statistical analysis was performed by using the software STATA 12.0. A total 1975 fracture cases and 4565 controls in 14 studies with a total of 16 eligible comparisons were identified for data analysis. RESULTS No evidence of relationship between the VDR BsmI, TaqI, ApaI or FokI polymorphisms and fracture risk was observed with any genetic model in postmenopausal women (BsmI: b vs. B: odds ratio (OR) 1.07, 95% confidence interval (CI) 0.90-1.29; TaqI: T vs. t: OR 0.89, 95% CI 0.68-1.15; ApaI: A vs. a: OR 0.91, 95% CI 0.76-1.08; FokI: F vs. f: OR 1.20, 95% CI 0.76-1.90). CONCLUSION This meta-analysis suggests that ApaI, BsmI, TaqI and FokI polymorphisms may be not associated with the risk of fracture in postmenopausal women. Further studies in a larger sample population are required to confirm this finding.

Abstract
In this study, we investigated humoral and cellular immune responses in mice to DNA vaccines containing individual S or M genes of a new type of reovirus (nRV) isolate from a severe acute respiratory syndrome (SARS) patient in Beijing, China. Mice were immunized intramuscularly (i.m.) with 100 μg of S1, S2, S3, S4, M1, M2, and M3 DNA vaccine each 4 times in 2-week intervals and assayed for humoral IgG, IgG1, IgG2, and IgG2b antibodies by ELISA and for cellular immune response, particularly IFN-γ induction by ELISpot assay. Moreover, CD4+ and CD8+ T cell levels in peripheral blood mononuclear cells were assayed by flow cytometry. We found that all DNA vaccines induced IgG antibodies, predominantly of the IgG2a class and S3 DNA vaccine was the strongest inducer. M2 and S3 DNA vaccines elicited Th1- and Th2-based immune responses, respectively, while S1 and M3 DNA vaccines induced a mixed Th1/Th2 response. M1, S2, and S4 DNA vaccines were poorly immunogenic. To our knowledge, this is the first report characterizing mammalian reovirus DNA vaccines applied to a mouse model.

Abstract
Nuclear factor erythroid-2-related factor 2 (Nrf2) is a critical cell protector by inducing phase two detoxifying and anti-oxidant enzymes in normal cells. But recently, numerous evidence show Nrf2 may play the same beneficial roles toward the cancer cells. Nrf2 is found upexpressed in lots of cancers and promote the proliferation and drug resistance. But studies about the role of Nrf2 in the metastases are few. It has been testified that the tumor cells are under hypoxic conditions. As an important anti-oxidant element, the expression of Nrf2 may be upregulated, which in turn promotes the tumor invasion and metastases in the hypoxic microenvironment. Our team found the expression of Nrf2 correlated with the lymph node metastasis of esophageal squamous cell carcinoma by pathological sections of esophageal carcinoma patients. Further, the mechanism beneath it was studied in this paper. It was hypothesized that the hypoxia microenvironment transformed Nrf2 a friend to a foe. First, Eca-109 cells were treated with different concentration of CoCl2 . Western blot and quantitative reverse transcription-polymerase chain reaction showed that with the increase of the concentration of CoCl2 , the expression levels of Nrf2 and hypoxia-inducible factor-1 (HIF-1) alpha were upregulated simultaneously. By analyzing the data, a significant correlation between Nrf2 and HIF-1 alpha in the protein levels was found. Further, blockage of Nrf2 mediated by shRNA suppressed the expression of HIF-1 alpha, hemeoxygenase-1 (HO-1), and matrix metalloproteinase 2 but enhanced the expression of E-cadherin. In addition, the results of wound healing and invasion assay-verified blockage of Nrf2 suppressed the migration and invasion. So it was suggested that blockage of Nrf2 repressed the migration and invasion of esophageal squamous cell carcinoma cells in the hypoxic microenvironment. HIF-1 alpha might be one of the downstream genes of Nrf2 regulated through Nrf2/HO-1 axis in the CoCl2 model. Nrf2 inhibition suppressed matrix metalloproteinase 2 and enhanced E-cadherin partly through HIF-1 alpha way.
