Abstract
BACKGROUND AND PURPOSE The aim of this study was to examine the association amongst remote diffusion-weighted imaging lesions (R-DWILs), imaging markers of cerebral small vessel disease (cSVD) and total cSVD burden in patients with primary intracerebral haemorrhage (ICH). METHODS In total, 344 consecutive primary ICH patients were enrolled prospectively. R-DWILs on magnetic resonance imaging as well as four imaging markers of cSVD, including cerebral microbleeds (CMBs), white matter hyperintensities (WMHs), lacunes and enlarged perivascular spaces, were rated with validated scales. The total cSVD score was calculated by adding up these four markers. Univariate and multivariate analyses were performed. RESULTS Remote DWI lesions were detected in 57 (16.6%) primary ICH patients. On multivariate logistic regression analysis, the presence of CMBs [odds ratio (OR) 5.26, 95% confidence interval (CI) 1.72-16.12], of high-grade WMHs (OR 4.68, 95% CI 2.01-10.90), the presence of lacunes (OR 2.69, 95% CI 1.20-6.06), mixed CMBs (OR 2.93, 95% CI 1.35-6.36), mixed lacunes (OR 3.60, 95% CI 1.25-10.37), periventricular WMHs (OR 2.19, 95% CI 1.40-3.44), deep WMHs (OR 1.92, 95% CI 1.24-2.97) and total WMHs (OR 1.52, 95% CI 1.20-1.94) were associated with the presence of R-DWILs. A significant association was also found between high-grade total cSVD score and R-DWILs (OR 1.97, 95% CI 1.36-2.84). This association remained significant in patients stratified by an age of 60 years or more than 60 years. CONCLUSIONS Remote DWI lesions are correlated with the severity of each imaging marker of cSVD and with the total burden of cSVD.

Abstract
We demonstrate, experimentally and theoretically, controlled loading of an exciton-polariton vortex chain into a 1D array of trapping potentials. Switching between two types of vortex chains, with topological charges of the same or alternating signs, is achieved by appropriately shaping an off-resonant pump beam that drives the system to the regime of bosonic condensation. In analogy to spin chains, these vortex sequences realize either a "ferromagnetic" or an "antiferromagnetic" order, whereby the role of spin is played by the orbital angular momentum. The ferromagnetic ordering of vortices is associated with the formation of a persistent chiral current. Our results pave the way for the controlled creation of nontrivial distributions of orbital angular momentum and topological order in a periodic exciton-polariton system.

Abstract
This study aimed to investigate the effects of in ovo feeding (IOF) of L-arginine (Arg) on energy metabolism in post-hatch broilers. A total of 720 eggs was randomly assigned to 3 treatments: 1) non-injected control group, 2) 0.75% NaCl diluent-injected control group, and 3) 1.0% Arg solution-injected group. At 17.5 d of incubation, 0.6 mL of each solution was injected into the amniotic fluid of each egg of injected groups. After hatching, 80 male chicks were randomly assigned to each treatment group with 8 replicates per group. The results showed that IOF of Arg increased glycogen and glucose concentrations in the liver and pectoral muscle of broilers at hatch (P < 0.05). The plasma glucose and insulin levels were higher in the Arg group than in the non-injected and diluent-injected control groups (P < 0.05). Meanwhile, IOF of Arg enhanced the hepatic glucose-6-phosphatase (G6P) activity at hatch (P < 0.05). There was no difference in hexokinase (HK) or phosphofructokinase (PFK) enzyme activities in the pectoral muscle in all groups. Further, IOF of Arg increased the phosphoenolpyruvate carboxykinase (PEPCK) and fructose-1,6-bisphosphatase (FBP) mRNA expressions at hatch (P < 0.05). In addition, broilers in the Arg group had a higher mRNA expression of glycogen synthase and a lower expression of glycogen phosphorylase in the liver and pectoral muscles than in the non-injected controls at hatch (P < 0.05). In conclusion, IOF of Arg solution enhanced liver and pectoral muscle energy reserves at hatch, which might be considered as an effective strategy for regulating early energy metabolism in broilers.

Abstract
Objective: Investigated the status quo of quality control of cancer chemotherapy in hospitals in Beijing to discover the main problems and provide the improvement measures. Methods: One medical record of cancer chemotherapy was taken every month for examination of quality control, and a total of 10 medical records in each hospital were examined. A total of 756 medical records from 76 hospitals were examined. Results: The results of analysis showed that the overall standardization and quality control of cancer chemotherapy was positively correlated with the grade of hospital. Only 36.8% of the hospitals were equipped with Pharmacy Intravenous Admixture Services (PIVAS). In terms of quality control of chemotherapy and medicine, the department of oncology had better performance than other departments (P<0.01). The scores of quality control of chemotherapy and medicine in the hospitals with clinical specialist pharmacists were 50.6 and 14.5, significantly higher than 47.2 and 12.7 of those without clinical specialist pharmacists (P<0.05). Conclusion: We should focus on the quality control of cancer chemotherapy in secondary hospitals, reinforce the training of oncology specialists, establish the admission system of oncologists, enhance the training of oncology clinical pharmacists and promote the standardization of cancer chemotherapy.

Abstract
BACKGROUND The effect of nephrectomy on development of anemia in living kidney donation has not been well studied. We hypothesized that the remaining kidney volume and function after donation are determinants of hemoglobin (Hb) concentration and postdonation anemia (PDA). METHODS We studied 398 living kidney donors (LKDs) who donated from January 2001 to December 2013. Demographic variables, hematologic variables, renal mass, and renal function were investigated as factors associated with PDA with the use of univariate and multivariable logistical regression analysis. Renal mass was determined from kidney volume measured with the use of computerized tomographic scans. RESULTS Prevalence of PDA in LKDs was 11.8% at a median follow-up time of 601 days. In univariate analyses, PDA was more prevalent in women than in men (72% vs 28%; P = .048). Age and race were not associated factors. Kidney volume was lower in donors with PDA than in those without PDA (326 ± 52 mL vs 368 ± 70 mL; P < .001). Donors with and without PDA had similar predonation and postdonation glomerular filtration rates. In the multivariable logistic regression analysis, total kidney volume and predonation anemia remained as independent factors associated with PDA. CONCLUSIONS PDA is prevalent after living kidney donation, with donor kidney volume and predonation hemoglobin levels being independent determinants for PDA.

Abstract
We demonstrate the generation of chiral modes-vortex flows with fixed handedness in exciton-polariton quantum fluids. The chiral modes arise in the vicinity of exceptional points (non-Hermitian spectral degeneracies) in an optically induced resonator for exciton polaritons. In particular, a vortex is generated by driving two dipole modes of the non-Hermitian ring resonator into degeneracy. Transition through the exceptional point in the space of the system's parameters is enabled by precise manipulation of real and imaginary parts of the closed-wall potential forming the resonator. As the system is driven to the vicinity of the exceptional point, we observe the formation of a vortex state with a fixed orbital angular momentum (topological charge). This method can be extended to generate higher-order orbital angular momentum states through coalescence of multiple non-Hermitian spectral degeneracies. Our Letter demonstrates the possibility of exploiting nontrivial and counterintuitive properties of waves near exceptional points in macroscopic quantum systems.

Abstract
This study was conducted to investigate the effects of in ovo feeding (IOF) of Arg solution on the hatchability, growth performance, gastrointestinal hormones, serum AA, activities of digestive enzymes, and mRNA expressions of sensing receptors and nutrient transporters in the jejunum of posthatch broilers. One thousand two hundred embryonated eggs with similar weight were randomly allocated to 5 groups consisting of 8 replicates of 40 eggs each. The 5 treatments were arranged as a noninjected control, a diluent-injected (0.75% NaCl solution) group, and Arg solution-injected groups with 0.5%, 1.0%, and 2.0% Arg, all dissolved in diluent. At 17.5 d of incubation, 0.6 mL of IOF solution was injected into the amniotic fluid of each egg of the injected groups. Results showed the hatchability of the 2% Arg group was lower (linear, = 0.025) than that of the other groups, and the BW of 21-d-old broilers increased (linear, = 0.008; quadratic, = 0.003) with increasing IOF concentration of Arg. The ADFI (linear, = 0.005; quadratic, = 0.001) and ADG (linear, = 0.010; quadratic, = 0.004) increased during d 1 to 21 with increasing IOF concentration of Arg. For 7- and 21-d-old broilers, the weights of digestive organs increased (linear, < 0.05) with increasing IOF concentrations of Arg; the greatest values were observed in the 1% Arg group. For 21-d-old broilers, IOF of the 1% Arg solution increased ( < 0.05) the concentrations of ghrelin and glucagon-like peptide 2; the activities of digestive enzymes, alkaline phosphatase, maltase, and sucrase in the jejunum; and the concentrations of serum AA of Val, Met, Ile, Leu, Arg, and Pro compared with those of the noninjected control and diluent-injected group. In ovo feeding of the 1% Arg solution also increased ( < 0.05) the mRNA expressions of jejunal sensing receptors of taste receptor type 1 members 1 and 3; the G protein-coupled receptor, class C, group 6, subtype A; nutrient transporters of solute carrier family 7, members 4, 6, and 7; sodium-glucose transporter 1; and fatty acid-binding protein 1. In conclusion, the 1% Arg solution was the appropriate injection level. In ovo feeding of the 1% Arg solution did not affect the hatchability but facilitated the release of gastrointestinal hormones, increasing the digestive and absorptive capacity and finally improving the growth performance of 21-d-old broilers. Therefore, IOF of the appropriate Arg solution could be an effective technology for regulating early nutrition supply and subsequent growth development in the poultry industry.

Abstract
This study aimed to investigate the effects of different dietary starch types on early postmortem muscle energy metabolism in finishing pigs. Ninety barrows (68.0±2.0kg) were randomly allotted to three experimental diets with five replicates of six pigs, containing pure waxy maize starch (WMS), nonwaxy maize starch (NMS), and pea starch (PS) (amylose/amylopectin were 0.07, 0.19 and 0.28 respectively). Compared with the WMS diet, pigs fed the PS diet exhibited greater creatine kinase activity, higher adenosine triphosphate and adenosine diphosphate contents, lower phosphocreatine (PCr), adenosine monophosphate and glycogen contents, and lower glycolytic potential (P<0.05). Moreover, the PS diet led to reduced percentage of bound hexokinase activity, decreased level of phosphorylated AKT (P<0.05) and increased level of hypoxia-inducible factor-1α (P<0.05). In conclusion, diet with high amylose content might promote PCr degradation and inhibit the rate of glycolysis, followed by attenuation of early postmortem glycolysis in finishing pigs.

Abstract
Silver, once regarded as a safe noble metal for humans, has been widely used in industrial and commercial products, especially in nanometer biomaterials. It is now well known that Ag+ is biologically active and is able to interact with the cell membrane, proteins and DNA. However, very little is understood about the potential impacts of Ag+ at the sub-cellular level. Our work investigated the potential toxicity of Ag+ on mitochondria isolated from rat livers by examining the mitochondrial morphology, respiration, swelling, membrane fluidity and reactive oxygen species (ROS) generation. We observed that Ag+ significantly affects the mitochondrial structure and function, including mitochondrial swelling, collapse of the transmembrane potential, change of permeability and fluidity, decline of the respiratory rate, and acceleration of ROS, indicating that Ag+ should be seriously regarded as a potentially hazardous substance. Moreover, we conclude that Ag+ injures the mitochondrial structure and function by a nonspecific approach, in which the interaction is unregulated by inherent parts such as the mitochondria permeability transition pore (MPTP). These results help us learn more about the toxicity of Ag+ at the subcellular (mitochondrial) level and influence future biological and medical applications of Ag-based materials.

Abstract
Two-dimensional capillary-gravity waves travelling under the effect of a vertical electric field are considered. The fluid is assumed to be a dielectric of infinite depth. It is bounded above by another fluid which is hydrodynamically passive and perfectly conducting. The problem is solved numerically by time-dependent conformal mapping methods. Fully nonlinear waves are presented, and their stability and dynamics are studied.

Abstract
Generalized solitary waves propagating at the surface of a fluid of finite depth are considered. The fluid is assumed to be inviscid and incompressible and the flow to be irrotational. Both the effects of gravity and surface tension are included. It is shown that in addition to the classical symmetric waves, there are new asymmetric solutions. These new branches of solutions bifurcate from the branches of symmetric waves. The detailed bifurcation diagrams as well as typical wave profiles are presented.

Abstract
We demonstrate, experimentally and theoretically, a Talbot effect for hybrid light-matter waves-an exciton-polariton condensate formed in a semiconductor microcavity with embedded quantum wells. The characteristic "Talbot carpet" is produced by loading the exciton-polariton condensate into a microstructured one-dimensional periodic array of mesa traps, which creates an array of phase-locked sources for coherent polariton flow in the plane of the quantum wells. The spatial distribution of the Talbot fringes outside the mesas mimics the near-field diffraction of a monochromatic wave on a periodic amplitude and phase grating with the grating period comparable to the wavelength. Despite the lossy nature of the polariton system, the Talbot pattern persists for distances exceeding the size of the mesas by an order of magnitude. Thus, our experiment demonstrates efficient shaping of the two-dimensional flow of coherent exciton polaritons by a one-dimensional "flat lens."

Abstract
OBJECTIVE To determine the prevalence of latent tuberculosis infection (LTBI) in college students. PATIENTS AND METHODS Four hundred and twenty newly admitted college students were enrolled. The Enzyme-Linked ImmunoSpot assay (ELISPOT) was used. Overall, 171 students with ELISPOT assay+/TST+ were monitored for three years to detect active TB disease. RESULTS The overall positive rate of ELISPOT assay was 40.7% among TST+ students. The ELISPOT positive rates were 36.9%, 45.4%, and 64.3% in groups of TST induration of 10-14mm, 15-20mm, and ≥20mm, respectively, with a significant difference (χ(2)=10.136, P<0.01) but no significant difference between BCG scar and no scar (41.2% vs. 38.8%; P>0.05). None of the 171 untreated students contracted active TB within the three-year monitoring period. CONCLUSION The LTBI rate might be overestimated by TST compared with interferon-γ release assays. On the basis of a close monitoring, few students developed active TB despite a positive result to the TST and ELISPOT assay.

Abstract
Pelvic lymphoceles/lymph fistulas are commonly observed after kidney allotransplantation, especially when the kidney is placed in a retroperitoneal position. While the majority are <5 cm in diameter and resolve without intervention, some may continue to enlarge, and cause local or systemic symptoms or graft dysfunction. Among 1662 recipients of both living and deceased donor kidney transplants between January 2003 and July 2014, we found 46 (2.7%) patients with symptomatic lymphoceles requiring intervention. We studied the clinical outcomes and charges for three treatment modalities including open surgical drainage (22), laparoscopic surgical drainage (11), and percutaneous fibrin glue injections into the drained lymphocele cavity (13). The patient demographics and clinical characteristics were comparable for each treatment group, although maintenance immunosuppressive drugs differed by era. We found fibrin glue injections resulted in significantly lower (p = 0.04) rates of recurrence (1; 7.7%) than either laparoscopic (6; 54%) or open surgical drainage (6; 27.3%). In addition, fibrin glue injections generated significantly (p < 0.001) lower median ($4559) charges compared to either laparoscopic ($26,330) or open surgical drainage ($23,758). Fibrin glue treatment has the advantage of being an outpatient procedure, performed with the patient under local anesthesia, and does not incur the expense of an operative procedure or hospital admission associated with laparoscopic or open surgery.

Abstract
Exciton-polaritons are hybrid light-matter quasiparticles formed by strongly interacting photons and excitons (electron-hole pairs) in semiconductor microcavities. They have emerged as a robust solid-state platform for next-generation optoelectronic applications as well as for fundamental studies of quantum many-body physics. Importantly, exciton-polaritons are a profoundly open (that is, non-Hermitian) quantum system, which requires constant pumping of energy and continuously decays, releasing coherent radiation. Thus, the exciton-polaritons always exist in a balanced potential landscape of gain and loss. However, the inherent non-Hermitian nature of this potential has so far been largely ignored in exciton-polariton physics. Here we demonstrate that non-Hermiticity dramatically modifies the structure of modes and spectral degeneracies in exciton-polariton systems, and, therefore, will affect their quantum transport, localization and dynamical properties. Using a spatially structured optical pump, we create a chaotic exciton-polariton billiard--a two-dimensional area enclosed by a curved potential barrier. Eigenmodes of this billiard exhibit multiple non-Hermitian spectral degeneracies, known as exceptional points. Such points can cause remarkable wave phenomena, such as unidirectional transport, anomalous lasing/absorption and chiral modes. By varying parameters of the billiard, we observe crossing and anti-crossing of energy levels and reveal the non-trivial topological modal structure exclusive to non-Hermitian systems. We also observe mode switching and a topological Berry phase for a parameter loop encircling the exceptional point. Our findings pave the way to studies of non-Hermitian quantum dynamics of exciton-polaritons, which may uncover novel operating principles for polariton-based devices.

Abstract
Abstract
Aims
Arthritis is the leading cause of chronic pain in European adults (painineurope.com). Arthritis-induced chronic pain is a major clinical problem that is frequently inadequately treated by current analgesics and results in significant reduction in the patient’s quality of life. Outcome measures used in pain research to assess injury-induced pain-like behaviours in preclinical models are often dependent on the assessment of withdrawal reflexes, typically evoked by mechanical or thermal stimuli.Advances inpre-dictive validity may be improved by assessing the global impact of pain and the reinstatement of innate behaviours suppressed by injury. Burrowing, an indicator of the global “wellbeing” of the animal can be objectively measured. We aimed to assess the impact of several preclinical modelsof arthritis onburrowing behaviour in mice.
Methods
The collagen antibody-induced arthritis (CAIA) pre-clinical model of rheumatoid arthritis, the complete Freund’s adjuvant (CFA), monosodium iodoacetate (MIA) and partial medial menisectomy (MMT) preclinical models of osteoarthritis were assessed in female and/or male C57/Black6J adult mice, comparing to control (salineorsham-operated) and naïve animals. Mechanical hypersensitivity using von Frey filaments and spontaneous burrowing behaviour were assessed over60days (CAIA), 14days (CFA), 28 days (MIA) and up to 200 days (MMT).
Results
We show the development of mechanical hypersen-sitivity in all preclinical models of arthritis, whereas spontaneous burrowing behaviour was altered differently between the preclin-ical models. A deficit in burrowing behaviour was observed in the preclinical models of osteoarthritis and a gain in burrowing behaviour noted in the preclinical model of rheumatoid arthritis, with no effect seen in the CFA model.
Conclusions
Burrowing behaviour appears more sensitive to detecting variation in preclinical models of arthritis when compared to mechanical hypersensitivity. Burrowing behaviour can detect both gain and deficits in the behaviour, which differs between preclinical models of rheumatoid and osteoarthritis.
