Abstract
The under-construction White Neutron Source (WNS) at China Spallation Neutron Source is a facility for accurate measurements of neutron-induced cross section. Seven spectrometers are planned at WNS. As the physical objectives of each spectrometer are different, the requirements for readout electronics are not the same. In order to simplify the development of the readout electronics, this paper presents a general method for detector signal readout. This method has advantages of expansibility and flexibility, which makes it adaptable to most detectors at WNS. In the WNS general-purpose readout electronics, signals from any kinds of detectors are conditioned by a dedicated signal conditioning module corresponding to this detector, and then digitized by a common waveform digitizer with high speed and high precision (1 GSPS at 12-bit) to obtain the full waveform data. The waveform digitizer uses a field programmable gate array chip to process the data stream and trigger information in real time. PXI Express platform is used to support the functionalities of data readout, clock distribution, and trigger information exchange between digitizers and trigger modules. Test results show that the performance of the WNS general-purpose readout electronics can meet the requirements of the WNS spectrometers.

Abstract
OBJECTIVE To determine the mechanism of sunitinib-induced autophagy in renal cell carcinoma cells. METHODS MTS assay was applied to detect the cell viability alteration under the treatment of sunitinib (2, 8 μmol/L). The sunitinib-induced autophagy as well as cell apoptosis was measured and compared after knocking down autophagy-related protein Beclin1 and microtubule associated protein 1 light chain 3 fusion protein (LC3) by RNA interference. The transmission electron microscope was used to observe the formation of autophagosomes in ACHN cells. The fluorescence microscope was used to monitor distribution and aggregation of endogenous LC3-II. The expressions of protein such as LC3-II, the autophagic regulation molecules protein kinase B/ mammalian target of rapamycin (Akt/mTOR) and the symbol of apoptosis poly ADP-ribose polymerase (PARP) were capable to be detected by immunoblotting assay. RESULTS Sunitinib was able to significantly trigger cell viability loss in the renal carcinoma cell ACHN, which was both in a concentration-dependent and time-dependent manner (P<0.05). After reducing the autophagy by knocking down Beclin1 and LC3, the number of cleavage of PARP was increased remarkably, whereas there was nearly not any cleavage in the mock group. By the transmission electron microscope, there were more autophagic vacuoles in ACHN cells after being administrated with sunitininb compared with the control. And the nuclear-to-cytosol translocation as well as aggregation of LC3-II was presented after sunitinib treatment by the fluorescence microscope, which was the proof of the enhanced autophagy. According to the immunoblotting, sunitinib was able to increase the accumulation of LC3-II . At the same time, the result of sunitinib combined with chloroquine, a drug which blocked the fusion of autophagosomes and lysosomes, demonstrated that the increasing amount of LC3-II was due to the enhanced autophagy flux by sunitinib treatment in ACHN cells. However, phosphorylation of Akt as well as mTOR was decreased at the same time. The rapamycin (mTOR inhibitor) or knocking down Akt subunits could change the sunitinib-induced LC3 -II accumulation, whereas overexpression of Akt subunits decreased the autophagic flux, indicating that Akt/mTOR was the target of sunitinib in autophagy. CONCLUSION Sunitinib induced autophagy via suppressing Akt/mTOR pathway, and the autophagy was involved in apopotosis.

Abstract
We report on four radio-detected cosmic-ray (CR) or CR-like events observed with the Antarctic Impulsive Transient Antenna (ANITA), a NASA-sponsored long-duration balloon payload. Two of the four were previously identified as stratospheric CR air showers during the ANITA-I flight. A third stratospheric CR was detected during the ANITA-II flight. Here, we report on characteristics of these three unusual CR events, which develop nearly horizontally, 20-30 km above the surface of Earth. In addition, we report on a fourth steeply upward-pointing ANITA-I CR-like radio event which has characteristics consistent with a primary that emerged from the surface of the ice. This suggests a possible τ-lepton decay as the origin of this event, but such an interpretation would require significant suppression of the standard model τ-neutrino cross section.

Abstract
Objective: The aim of this double-masked, placebo-controlled trial was to confirm the anaesthetic effect of EMLA cream compared with placebo when used for sharp debridement of venous leg ulcers and to test its feasibility with respect to the usual procedure. Methods: One hundred and ten patients with venous ulcers were randomised to EMLA or placebo cream treatment for 30-45 min. Pain from debridement was evaluated by the patient on a 100 mm visual analogue scale (VAS) and by the physician on a verbal scale. Results: The median VAS scores were 16.5 and 52 in EMLA- and placebo-treated patients, respectively (p<0.00001), a clinically relevant difference. On the vertebral scale 61% of EMLA patients and 21% of placebo patients were placed in the category of no pain (pO.OOOl). The physicians found debridement with EMLA easier to perform (p<0.01). Conclusion: Debridement of venous leg ulcers using topical anaesthesia is easy and safe, with adequate pain relief in both in- and outpatients.

Abstract
AIM To evaluate oxygenation changes in rat subcutaneous C6 gliomas using blood-oxygen-level dependent (BOLD) functional magnetic resonance imaging (fMRI) combined with non-haemodynamic response function (non-HRF) analysis. MATERIALS AND METHODS BOLD fMRI were performed during carbogen inhalation in 20 Wistar rats bearing gliomas. Statistical maps of spatial oxygenation changes were computed by a dedicated non-HRF analysis algorithm. Three types of regions of interest (ROIs) were defined: (1) maximum re-oxygenation zone (ROImax), (2) re-oxygenation zones that were less than the maximum re-oxygenation (ROInon-max), and (3) zones without significant re-oxygenation (ROInone). The values of percent BOLD signal change (PSC), percent enhancement (ΔSI), and significant re-oxygenation (T) were extracted from each ROI. Tumours were sectioned for histology using the fMRI scan orientation and were stained with haematoxylin and eosin and CD105. The number of microvessels (MVN) in each ROI was counted. Differences and correlations among the values for T, PSC, ΔSI, and MVN were determined. RESULTS After carbogen inhalation, the PSC significantly increased in the ROImax areas (p<0.01) located in the tumour parenchyma. No changes occurred in any of the ROInone areas (20/20). Some changes occurred in a minority of the ROInon-max areas (3/60) corresponding to tumour necrosis. MVN and PSC (R=0.59, p=0.01) were significantly correlated in the ROImax areas. In the ROInon-max areas, MVN was significantly correlated with PSC (R=0.55, p=0.00) and ΔSI (R=0.37, p=0.00). CONCLUSIONS Statistical maps obtained via BOLD fMRI with non-HRF analysis can assess the re-oxygenation of gliomas.

Abstract
Bone marrow-derived mesenchymal stem cells (BMSCs) can be recruited to tumor sites and integrate into the stroma of tumors. When co-cultured with BMSCs, otherwise weakly metastatic nasopharyngeal carcinoma cells (NPC) showed improved metastatic ability. BMSCs in the tumor environment displayed the characteristics of macrophages. Nitric oxide produced by BMSCs in tumor environment could translocate caldesmon to podosome in Ca2+/calmodulin manner and promoted metastatic ability of NPC cells through invadopodia formation, with which the NPC cells degrade the extracellular matrix. Thus, we concluded that the BMSCs promoted cell migration and invasion through nitric oxide-induced paracrine signals.

Abstract
Lung cancer commonly metastasizes to lymph nodes, brain and bones, which is the main cause of death. It is still a challenge to detect molecular biomarkers for early diagnosis and therapeutics of lung cancer. Our previous study found that bone marrow-derived stroma cells (BMSCs) under tumor microenvironment produced nitric oxide (NO), which was induced by inducible nitric oxide synthase (iNOS), and promoted invasion and metastasis of cancer cells by remodeling cytoskeleton. The aim of this study is to elucidate the relationship between the expressions of iNOS, cytoskeleton protein caldesmon, OPN, and clinical parameters especially the metastasis of lung cancer. We found that nitric oxide can remodel cytoskeleton and promoted the mobility of lung cancer cells. The expressions of iNOS, caldesmon, and OPN are closely correlated to metastasis of lung cancer. The intracranial metastatic tissue samples of lung cancer showed significantly higher expression of iNOS, caldesmon and OPN. A flow-cytometry analysis for peripheral blood of lung cancer patients showed increased EPCAM+/OPN+ cells in circulation of patients with bone metastasis compared to that of patients without metastasis, which is indicative of cancer circulating cells. The concentration of serum OPN was also positively related to the bone metastasis of lung cancer. Taken together, these results suggested that iNOS, caldesmon and OPN may work as biomarkers for metastasis of lung cancer.

Abstract
Tall fescue (Festuca arundinacea Schreb), a predominant cool-season perennial grass, is widely used as forage and turf grasses in China. In July 2013, powdery mildew was observed on 10 F. arundinacea lawns (about 0.5 ha in total) in Urumchi, Xinjiang Province, China, with 20 to 30% of the area being infected. Signs of the disease initially appeared as irregular white mycelial colonies on the adaxial surface of infected leaves. As the disease progressed, the colonies covered the whole adaxial surface and white patches appeared on the abaxial surface of infected leaves. Conidiophores were unbranched and cylindrical with swollen bases, measuring 13.3 to 15 × 16.7 to 20 μm, and borne vertically on hyphae. Each conidiophore produced 10 to 18 conidia in a chain. The conidia were oval, one-celled, and colorless, measuring 8.1 to 9.8 × 26 to 29.7 μm. Cleistothecia were black, spherical, and 164.3 to 207.3 μm in diameter, each of which contained 9 to 26 asci. Asci were oblong or ovate, measuring 32.1 to 40 × 85.7 to 96.4 μm. Asci were petiolate, containing eight ascospores. Ascospores were round to oval, colorless, one-celled, measuring 19.1 to 22.5 × 11.7 to 13.6 μm. Based on morphological characteristics of the anamorph and the teleomorph, the fungus was identified as Blumeria graminis (DC.) Speer. Additionally, the internal transcribed spacer (ITS) of 563 bp was amplified from DNA of conidia using ITS1 and ITS4 primers (4). The ITS sequence was deposited in GenBank (Accession No. KF545644). The ITS sequence showed 100% homogeneity with those of B. graminis on Poa pratensis in Swizerland (AB273540) and on P. bulbosa in Iran (AB273551) (1), which further confirmed the identification. Ten 3-week-old healthy plants were inoculated by spraying a spore suspension (1 × 105 conidia ml-1) made from conidia brushed from infected plants, and 10 plants sprayed with sterile distilled water were served as controls. All the plants were placed in the same growth chamber at 20°C, 80% humidity, and 16-h photoperiod. Twenty days after inoculation, typical signs and symptoms of powdery mildew were observed on all the inoculated plants, whereas no symptoms were observed on the controls. Microscopic and ITS analysis showed that the fungus on the inoculated plants is identical to that on diseased field plants. B. graminis on F. arundinacea has been observed in a few European countries (1), Israel (3), and the United States (2). To our knowledge, this is the first report of powdery mildew caused by B. graminis on F. arundinacea in China, which will increase the difficulty to prevent powdery mildew on grasses including cereals.

Abstract
Swiss chard (Beta vulgaris L. subsp. cicla) is a widely planted vegetable in China. From May to June 2013, an outbreak of powdery mildew on Swiss chard cultivar Fangzheng was observed in the commercial fields in Zhoukou city of Henan Province, located in central China. More than 80% of the plants exhibited symptoms of the disease. At the beginning of infection, circular, white, dust-like colonies of powdery mildew occurred mainly on adaxial surfaces of leaves. As the disease progressed, white mycelia covered the foliar parts of plant. No cleistothecia were found on or in collected samples. Upon microscopic evaluation, conidiophores were unbranched with the length of 63 to 126 and width of 7 to 10 μm (n = 50), produced conidia singly, and composed of a cylindrical foot cell followed by one to three short cells. Conidia were colorless, hyaline, ovoid, measured 29 to 40 × 12 to 18 μm (n = 100), lacked fibrosin bodies, and produced germ tubes on the ends of the conidia. The fungus was identified as Erysiphe betae according to the morphological features (1). To verify the identity, the internal transcribed spacer (ITS) region was amplified with the universal primers ITS1 and ITS4 (2) and sequenced. The ITS sequence obtained was assigned as Accession No. KF268348 in GenBank, which showed 100% homogeneity with two ITS sequences of E. betae isolates from UK (DQ164432 and DQ164436). Koch's postulates were conducted by inoculating 15 healthy 5-week-old plants (cv. Fangzheng) with detached infected leaves, which grew in a growth chamber under 22/16°C (day/night), 50% relative humidity, 120 μmol/m2/s light and a 16-h photoperiod. Fifteen non-inoculated plants grew in another growth chamber with the same conditions as control. Symptoms consistent with the infected field plants were observed on the inoculated plants, while no symptoms were found on the control plants. Microscopic observation revealed that the pathogen growing on the inoculated plants was consistent with the morphology of the original fungus. To our knowledge, this is the first report of E. betae infection on Swiss chard in China (3). References: (1) S. Francis. Mol. Plant Pathol. 3:119, 2002. (2) T. J. White et al.

Abstract
AIM Dilation of one or both common iliac arteries (CIAs) is a major concern in endovascular aneurysm repair (EVAR). One option for CIA aneurysm repair is hypogastric embolization followed by endograft extension into the external iliac artery. However, hypogastric occlusion does not always go unpunished and it may lead to ischemic complications. Aim of the paper was to evaluate early results with the Gore® Excluder® Iliac Branch Endoprosthesis (IBE) in the treatment of iliac aneurysms associated or not with abdominal aortic aneurysms. METHODS Between November 2013 and April 2014, in our Institution 7 Gore IBE were implanted in 5 patients. Technical success, 30-day mortality and complications were investigated. RESULTS Technical success and branch patency was 100%. There was no 30-day mortality. In 1 of the 2 bilateral cases an endovascular relining with bare stents was required due to a compression of iliac legs at level of aortic bifurcation. CONCLUSION Use of Gore IBE device in the treatment of aorto-iliac disease is feasible and safe. Late results are necessary to evaluate the performance of this endograft in the long term.

Abstract
INTRODUCTION Exercise has been recommended to increase bone mass and prevent osteoporosis. While current treatment of osteoporosis mainly involves the use of antiresorptive agents, it is unclear whether there are any additive effects in improving bone mass when antiresorptive agents and exercise are jointly used. METHODS A structured and comprehensive search of databases was undertaken along with hand searching of key journals and reference lists. The combined interventions of antiresorptive agents and exercise were examined for their additive effects on lumbar spine bone mineral density (BMD) among adults with low bone mass. Trial quality was assessed using the Jadad quality score. Study outcomes for analysis, absolute change (grams per square centimeter) or relative change (in percent) in BMD, at the lumbar spine were compared by calculating standardized mean difference (SMD) using fixed and random effect models. RESULTS Seven randomized controlled trials (RCT) met the predetermined inclusion criteria. The increase in lumbar spine BMD of the combined-intervention group was significantly greater than that of the antiresorptive agent-alone group (fixed effect model: SMD = 0.55; 95% confidence interval (CI) = 0.36, 0.75; overall effect Z-value = 5.51; p < 0.00001). Subgroup analyses also showed consistent results. Methodological quality of most included studies was scored 3 by the Jadad criterion, and publication bias was slight according to funnel plots. CONCLUSION It was found that combining antiresorptive agents with exercise had additive effects on improving lumbar spine bone mass gains in adults with low bone mass. To verify the additive effects further, more RCTs with longer duration and larger sample sizes are needed.

Abstract
Minimally invasive surgical solutions for patients with extensive aortic disease are eagerly awaited, since open repair is often associated with high rates of morbidity and mortality. In the last decade, the development of fenestrated and branched aortic endografts has offered a therapeutic option to patients deemed unsuitable for major surgery. Preliminary studies showed promising early results, while mid- and long- term data are scarce. The aim of this paper was to review current results of total endovascular repair of thoracoabdominal aortic aneurysms (TAAA) with a single model of endograft in the published literature. A literature search was conducted, and our two-center experience with fenestrated and branched endografts in the treatment of TAAA, with the Cook Zenith endograft, is presented. Early results show perioperative mortality rates ranging from 0% to 21%, spinal cord ischemia from 0% to 33.3%. At a mean follow up ranging from 9 to 19 months, reinterventions are needed in 3.3% to 25% of the cases, with a mid term visceral branch patency of 90% to 100%. Current experiences with total endovascular TAAA repair show promising results, in selected centers with large experience in complex aortic endografting. With increasing follow- up times, need for reintervention is growing, while aneurysm-related deaths remain rare. Long-term results are still lacking, but these encouraging data and further technological developments will support wider adoption of the technique.
