Abstract
BACKGROUND Hypoxia plays a crucial role in the development of solid tumors. Hypoxia-inducible factor-1alpha (HIF-1alpha) is essential for this process, and has been suggested to be a target for cancer therapy. New therapeutic approaches for pancreatic cancer are needed owing to the extremely poor prognosis, in large part as a consequence of high rates of metastasis. The mechanism remains to be explored. AIM To illustrate the role of hypoxia-inducible factor-1alpha in pancreatic cancer metastasis and the value of the molecule as a target for pancreatic cancer therapy. MATERIALS AND METHODS To address this shortcoming, we used both in vitro and in vivo approaches to evaluate the overall effects of HIF-1alpha on pancreatic cancer. We used a plasmid encoding small interfering RNAs (SiRNAs) to silence HIF-1alpha expression in the Panc-1 pancreatic cancer cell line, and used a series of assays to detect changes in gene expression at the protein and mRNA levels, cell proliferation, cell apoptosis, and the abilities of cells to migrate under both hypoxia and normoxia conditions. RESULTS Both in vitro and in vivo analysis suggested that hypoxia significantly promotes cell proliferation and migration, resulting in metastasis. Pancreatic cancer cells in which HIF-1alpha expression was inhibited were less invasive, with reduced resistance to hypoxia, impaired migration, and reduced capacity to cause metastasis. CONCLUSIONS HIF-1alpha may be a dominant factor driving the metastatic progression of pancreatic cancer and can be a potent therapeutic target for the disease.

Abstract
Our previous study suggested that green light promotes broiler growth during the early stage [posthatching day (P) 0 to P26], and blue light enhances growth during the later stage (P27 to P49). The purpose of this study was to improve broiler growth and productive performance by using a combination of monochromatic lights at critical points between the early and later stages of growth. A total of 512 male Arbor Acres broilers on P0 were reared under white light (W), red light (R), green light (G), and blue light (B) by using light-emitting diode lamps at 15 ± 0.2 lx from P0 to P26 (16 replicate pens/group, 8 birds/pen), and then switching to another color of light until P49 (4 replicate pens/group, 8 birds/pen). As compared with single monochromatic lights, broilers reared in environments under combinations of monochromatic lights, W→G, R→B, G→B, and B→G, attained heavier BW than those reared in environments under W→W (3.18 to 12.00%), R→R (1.96 to 18.14%), G→G (0.85 to 5.08%), and B→B (0.39 to 4.70%), respectively. In addition, feed conversion ratios in the W→B, R→B, and G→B combinations were lower than feed conversion ratios for W→W (15.86%, P < 0.05), R→R (18.41%, P < 0.05), and G→G (3.37%), respectively. Moreover, the eviscerated carcass weight and breast, thigh, and crus muscle weights under G→B were greater by 0.40 to 56.23% than were those for the other light groups except W→B (eviscerated carcass) and B→G (breast muscle). The results suggest that the application of the G→B and B→G exchanges can be used successfully to improve growth and productive performance in broilers.

Abstract
Based on 106×10(6)ψ(3686) events collected with the BESIII detector at the BEPCII facility, a partial wave analysis of ψ(3686)→ppπ0 is performed. The branching fraction of this channel has been determined to be B(ψ(3686)→ppπ0)=(1.65±0.03±0.15)×10(-4). In this decay, 7 N* intermediate resonances are observed. Among these, two new resonances, N(2300) and N(2570) are significant, one 1/2+ resonance with a mass of 2300(-30-0)(+40+109) MeV/c2 and width of 340(-30-58)(+30+110) MeV/c2, and one 5/2- resonance with a mass of 2570(-10-10)(+19+34) MeV/c2 and width of 250(-24-21)(+14+69) MeV/c2. For the remaining 5 N* intermediate resonances [N(1440), N(1520), N(1535), N(1650) and N(1720)], the analysis yields mass and width values that are consistent with those from established resonances.

Abstract
OBJECTIVES This study evaluated the expression profile of the mesothelin (MSLN) gene and its prognostic significance in breast cancer. METHODS To evaluate the diagnostic and prognostic significance of mesothelin, immunohistochemistry was used to assess the level of mesothelin protein in surgically resected, formalin-fixed, paraffin-embedded invasive breast carcinoma specimens. Associations between mesothelin and other biomarkers, including oestrogen receptor (OR), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2/neu), were also evaluated. RESULTS A total of 182 breast carcinoma specimens were included. Mesothelin protein was present in the membrane of malignant cells. There was correlation between the presence of mesothelin in tumour cells and tumour infiltration of the lymph node. There was no correlation between the presence of mesothelin and HER2/neu protein, OR and PR in tumour cells. Mesothelin levels were significantly associated with decreased overall survival. CONCLUSIONS Lymph node status, tumour size, HER2/neu and mesothelin protein levels in breast cancer cells were independent prognostic factors. Mesothelin could be useful as a prognostic marker of overall survival in invasive breast cancer.

Abstract
OBJECTIVE To investigate whether inhibition of Akt phosphorylation by the phosphatidylinositol 3-kinase (PI3K) inhibitor, wortmannin, reduces metastasis and angiogenesis in a human breast cancer cell line via nuclear factor (NF)-κB-dependent matrix metalloproteinase (MMP)-9 and interleukin (IL)-8 pathways. METHODS MDA-MB-231 cells were treated with wortmannin 0-200 nM for 4 h. Restoration of Akt activity was evaluated by transfection of cells with constitutively active myristoylated Akt (myr-Akt). NF-κB, MMP-9 and IL-8 proteins were detected by electrophoretic mobility shift assay, Western blot or enzyme-linked immunosorbent assay. The chicken embryo chorio-allantoic membrane assay, cell motility and migration assays were used to evaluate angiogenesis and invasion in vitro. A mouse pseudo metastatic breast cancer model was used to assess the effects of wortmannin on metastasis and angiogenesis in vivo. RESULTS Wortmannin inhibited the phosphorylation of Akt, upregulation of NF-κB, MMP-9, IL-8, and in vitro cell invasion and angiogenesis, in a dose-dependent manner. Transfection of myr-Akt reversed the cellular and biochemical effects of wortmannin in vitro. Wortmannin also significantly inhibited tumour metastasis and angiogenesis in vivo. CONCLUSION The findings of the present study suggest that wortmannin inhibits metastasis and angiogenesis in breast cancer cells via PI3K/Akt/NF-κB-mediated MMP-9 and IL-8 signalling pathways.

Abstract
The aim of this study was to investigate human papillomavirus type 16 (HPV16) prevalence in esophageal squamous cell carcinoma (ESCC) in Xinjiang Kazakh patients and its role in ESCC carcinogenesis. One hundred and fifty cases of ESCC and 150 cases of corresponding normal esophageal mucosa (CNGM) samples were collected from north Xinjiang where the Kazakh ethnic group has lived since ancient times. HPV16 infection in ESCC and CNGM was detected by genotype-specific polymerase chain reaction. HPV16 DNA was detected in 55 of 150 ESCC samples (36.7%) and 24 of 150 corresponding normal esophageal mucosa samples (16%) with significant differences (P < 0.001, odds ratio = 3.039, 95% confidence interval: 1.756-5.260). No statistically significant correlations were found between HPV16 infection and the age or gender of patients, tumor site, tumor cell differentiation, or lymph node metastasis (P > 0.05). HPV16 infection is common in cases of ESCC in the Kazakh ethnic group in Xinjiang and may be involved in ESCC carcinogenesis.

Abstract
OBJECTIVES We analyzed the clinical features of 138 patients with primary immunodeficiency (PID) and performed genetic testing on a subset of patients in order to complete gaps in research on PID in South China and thus improve pediatricians' ability to recognize and diagnose PID. METHODS We performed a retrospective analysis based on the medical records of PID patients hospitalized in our institution between May 1999 and June 2012. Gene sequencing was performed in 59 cases. RESULTS Children with PID usually present with fever and repeated infections that generally affect the respiratory and digestive tracts. Growth retardation is observed in some cases. Of the 138 patients, 113 were boys, median age at onset was 5 months (range, 0-119 months), and age at diagnosis was 10 months (2-159 months). A family history of repeated infection or death of family members in infancy because of recurrent infections was recorded in 20 cases (14.49%). Antibody defects were detected in 48 cases (34.78%), combined immunodeficiency disease in 45 cases (32.61%), and other well-defined immunodeficiency syndromes in 45 cases (32.61%). Of the 59 patients from the genetic subanalysis, 24 (15.94%) had a genetic mutation (x-linked agammaglobulinemia, 8 cases; severe combined immunodeficiency, 8 cases; hyperimmunoglobulin M syndrome, 3 cases; hyperimmunoglobulin E syndrome, 3 cases; chronic granulomatous disease, 2 cases). We detected 4 novel mutations. No relevant mutations were found in the remaining 35 cases.After treatment with intravenous immunoglobulin and anti-infectious agents, 16 patients died in hospital, and 5 cases died after discontinuing treatment (mortality, 15.22%). CONCLUSIONS In recent years, the number of patients with PID has risen gradually in South China. Genetic testing can confirm diagnosis. Since PID seriously affects children's quality of life, it is important to diagnose, treat, and intervene early.We hope our clinical and genetic analyses of children with PID can provide diagnostic guidance for clinicians.

Abstract
BACKGROUND The dimorphic fungus Sporothrix schenckii is the etiological agent of sporotrichosis, an important cutaneous mycosis with a worldwide distribution. At present, it is challenging to rapidly discover and identify Sporothrix schenckii in biopsy tissues nowadays. AIMS To explore new methods for rapid diagnosis of sporotrichosis. MATERIALS AND METHODS We screened specific primers for Sporothrix schenckii using 50 clinical isolates from patients with sporotrichosis. DNA was extracted from the lesions of 30 cases of clinically suspected sporotrichosis using the Graham s method of CTAB and amplified by PCR using the screened specific primers. RESULTS The primer S2-R2 was applicable for the identification of S. schenckii from different geographic areas and clinical types with high specificity and sensitivity. Twenty-five out of the thirty cases (83.3%) amplified using the primer S2-R2 showed positive bands. Further positive bands were observed in 95.6% of cases tested positive by fungal culture. CONCLUSIONS Using the PCR technique and specific primers, we developed a new diagnostic method that can rapidly diagnose sporotrichosis with tissues obtained from clinical biopsies.

Abstract
Abstract
The sustainment characters of cancer stem cells (CSCs) such as self-renew and differentiation to other tumor cells greatly depend on the tumor microenvironment, which is composed of many components, e.g. vasculature, extracellular matrix, epithelial cells, stromal cells, as well as nutrients and oxygen. As vasculature is an important factor for the CSC and tumor development, the understanding of their spatial patterns is essential for calibrating the CSC-microenvironment interactions in mathematical modeling. In this study, we acquired the vasculature in side tumors and normal breast tissues by using two-photon fluorescence microscopy, which enables 3D in vivo imaging. We developed an advanced vasculature segmentation approach for an objective and accurate quantification of the vasculature in 3D image volumes. The approach integrates supervoxel analysis and the orientation guided hidden Markov random field (ori-HMRF) modeling together to compensate for low quality images, e.g., low signal-to-noise ratio (SNR) and uneven background. By constructing a new feature space that combines the CIELAB color space and the coordinates space, the supervoxel analysis divides an image volume into subregions with local similar intensity and restricted regular shape, boundaries of which can delineate the vasculature boundaries accurately even in low intensity contrast regions. We further designed a set of features for the separation of blood vessel regions from the background. To make use of the context information, i.e. the continuity of vasculature, the ori-HMRF model is used to incorporate the consistency of vasculatures' orientation in order to reduce the false positives and negatives. Experimental results on image volumes from both breast cancer and normal breast tissues show that the proposed method can effectively reconstruct the vasculature structure with the CSC embedded tumor microenvironment.

Abstract
Dexamethasone has been widely used before general anesthesia induction. However, previous studies have found that a pre-induction bolus dose of dexamethasone sometimes causes perineal pruritus. We hypothesized that an appropriate prolongation of the injection time might suppress dexamethasone-induced perineal pruritus. Four hundred patients requiring general anaesthesia were randomly allocated into four groups: group I receiving 2 ml dexamethasone (5 mg/ml); group II receiving 4 ml dexamethasone (2.5mg/ml); group III receiving 10 ml dexamethasone (1 mg/ml); and group IV receiving 20 ml dexamethasone (0.5 mg/ml). Dexamethasone was diluted with 0.9% sodium chloride. The injection time of dexamethasone was 5s in groups I, II and III; while the injection time of dexamethasone was 30s in group IV. Occurrence of perineal pruritus was significantly reduced in Group IV (0% vs 38%, 32% and 12% in Groups I, II and III, respectively, p < 0.05). The incidence was higher in females than in males (p < 0.05). The duration of perineal pruritus was longer in females than in males in groups I, II and III (p < 0.05). We conclude that the dilution of dexamethasone to 0.5 mg/ml with 0.9% sodium chloride combined with prolonged injection time to 30 s eliminates dexamethasone-induced perineal pruritus.

Abstract
Early detection of invasive species is critical for effective biocontrol to mitigate potential ecological and economic damage. Laser transmission spectroscopy (LTS) is a powerful solution offering real-time, DNA-based species detection in the field. LTS can measure the size, shape and number of nanoparticles in a solution and was used here to detect size shifts resulting from hybridization of the polymerase chain reaction product to nanoparticles functionalized with species-specific oligonucleotide probes or with the species-specific oligonucleotide probes alone. We carried out a series of DNA detection experiments using the invasive freshwater quagga mussel (Dreissena bugensis) to evaluate the capability of the LTS platform for invasive species detection. Specifically, we tested LTS sensitivity to (i) DNA concentrations of a single target species, (ii) the presence of a target species within a mixed sample of other closely related species, (iii) species-specific functionalized nanoparticles versus species-specific oligonucleotide probes alone, and (iv) amplified DNA fragments versus unamplified genomic DNA. We demonstrate that LTS is a highly sensitive technique for rapid target species detection, with detection limits in the picomolar range, capable of successful identification in multispecies samples containing target and non-target species DNA. These results indicate that the LTS DNA detection platform will be useful for field application of target species. Additionally, we find that LTS detection is effective with species-specific oligonucleotide tags alone or when they are attached to polystyrene nanobeads and with both amplified and unamplified DNA, indicating that the technique may also have versatility for broader applications.

Abstract
The two-photon transition ψ(3686)→γγJ/ψ is studied in a sample of 1.06×10(8) ψ(3686) decays collected by the BESIII detector. The branching fraction is measured to be (3.1±0.6(stat)(-1.0)(+0.8)(syst))×10(-4) using J/ψ→e(+)e(-) and J/ψ→μ(+)μ(-) decays, and its upper limit is estimated to be 4.5×10(-4) at the 90% confidence level. This work represents the first measurement of a two-photon transition among charmonium states. The orientation of the ψ(3686) decay plane and the J/ψ polarization in this decay are also studied. In addition, the product branching fractions of sequential E1 transitions ψ(3686)→γχ(cJ) and χ(cJ)→γJ/ψ(J=0,1,2) are reported.

Abstract
Abstract. Lambs from birth (0-day-old) to 56-day-old were selected in present study to investigate developmental changes of growth hormone receptor (GHR) and insulin-like growth factor I (IGF-I) mRNA expression in their rumen tissue. Forty-five lambs (5 lambs per group) were slaughtered at 0, 7, 14, 21, 28, 35, 42, 49, 56 days of age respectively for sampling the tissue of the rumen dorsal sac. The abundance of GHR and IGF-I mRNA were detected through real-time quantitative PCR method. The results indicated that the expression levels of GHR and IGF-I mRNA had similar change tendency in rumen tissue that the GHR and IGF-I mRNA abundance decreased with age from birth to 56-day-old. There was significant positive correlation between the two gene mRNA expression levels. The results suggested that GHR and IGF-I gene expression levels had the specific developmental pattern in rumen tissue.

Abstract
A palladium particle-modified carbon fiber microdisk array electrode was designed and employed in capillary electrophoresis for the simultaneous detection of hydrazine, methylhydrazine, and isoniazid. The Pd-modified microdisk electrode had high catalytic ability for hydrazines and exhibited good reproducibility and stability. The response for hydrazine was linear over 3 orders of magnitude with a correlation coefficient of 0.993. The detection limits for hydrazine, methylhydrazine, and isoniazid were 1.2, 2.1, and 6.2 pg, respectively.

Abstract
This study aimed to investigate the effects of RhoGDIα knockdown on apoptosis and the chemosensitivity of lung cancer cells to paclitaxel. The signaling proteins involved were also assessed. RhoGDIα expression was assessed by RT-PCR, Western blotting and immunohistochemistry. Apoptosis was determined by flow cytometric assessment, and cell viability was measured with the MTT assay. Phosphorylation levels of signaling proteins, ERK, JNK, Akt, Bad and IκBα were tested by Western blotting and immunohistochemistry. Positivity for RhoGDIα in lung cancer tissues was significantly higher than in paracancerous tissues. Downregulation of RhoGDIα was associated with significantly increased apoptosis and repressed cell viability. This effect could be due to the consequent upregulation of p-JNK, as well as decreased levels of p-ERK, p-Bad and p-IκBα. Knockdown of RhoGDIα strengthened the effect on apoptosis and inhibition of cell viability induced by paclitaxel treatment. This chemosensitization effect could be a result of the intensification of pro-apoptotic JNK activation, and repression of anti-apoptotic p-ERK, p-Bad and p-IκBα expression stimulated by paclitaxel. In summary, our study indicated that RhoGDIα could be a promising therapeutic target, and the combination of RhoGDIα siRNA and paclitaxel might be a valuable potential therapy for lung cancer treatment.
