Abstract
Objective:To investigate the effect of Notch1 gene on radiosensitivity of nasopharyngeal carcinoma cells and its molecular mechanism. Method:A Notch1-knockout CNE-2 cell line was constructed using CRISPR/Cas9 system, and the expression of Notch1 gene was detected by RT-PCR and Western blot. After treatment with different doses of radiation, the survival fraction (SF) of each group was calculated, and used the GraphPad Prism 6.0 software and the Linear quadratic model were used to calculate the fitted dose survival curve and the sensitivity enhancement ratio(SER). Taking 6 Gy as radiation dose, the experiment was divided into four groups: Notch1(+) group, Notch1(-) group, IR+Notch1(+) group and IR+Notch1(-) group. CCK-8 assay was used to detect cell proliferation in each group. Annexin V-FITC/PI double staining assay was used to detect the changes of apoptosis in each group. The expression of H2AX, CyclinD1, Bax, Bcl-2 and GAPDH proteins were detected by Western blot. Result:The CNE-2 cell line with Notch1 gene knockout was successfully constructed. The clonogenic assay showed knockout of Notch1 enhanced the radiosensitivity of NPC cells. The CCK-8 assay showed that cell proliferation and cell viability were significantly reduced in the IR+Notch1(-) group compared with the IR+Notch1(+) group(P<0.05). Annexin V-FITC/PI double staining assay showed that the IR+Notch1(-) group had the highest apoptosis rate compared with the other groups (P<0.05). Western blotting demonstrated that the expression of γH2AX was significantly increased after irradiation of Notch1 nasopharyngeal carcinoma cells, the expression of Cyclin-D1 was increased, and the ratio of Bax:Bcl-2 was higher. Conclusion:Knockout of Notch1 signaling molecule can effectively improve the radiosensitivity of NPC cells cultured in vitro, which may be a potential target for radiosensitization of NPC.

Abstract
SummaryTobacco smoke exposure has obvious and complex effects on the immune system of the human upper respiratory tract, including pro-inflammatory and anti-immune effects. Exposure to tobacco smoke is closely related to the occurrence and development of allergic rhinitis, the common rhinitis and sinusitis. The innate immune system is influenced by tobacco smoking through its effects on the respiratory mucosa and its adjuncts, natural killer cells, dendritic cells, neutrophils and innate immune receptors. Cigarette smoke can also affect the humoral immunity and cellular immunity, altering the acquired immune condition of the upper respiratory tract. Tobacco smoke exposure promotes the occurrence and development of the upper respiratory tract infectious diseases and allergic diseases by changing the composition of microflora in the upper respiratory tract.

Abstract
Objective: To investigate the relationship between single nucleotide polymorphism(SNP) of vitamin D receptor(VDR) gene with susceptibility to allergic rhinitis(AR). Method: Two hundred and ten AR patients were selected as AR group, and 180 healthy volunteers from the same period were selected as control group. Fasting venous blood was collected from all subjects and blood DNA was extracted. Polymorphisms at ApaⅠ(rs7975232) and FokⅠ(rs2228570) loci of VDR gene were detected by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP), and the relationships between different genotypes with susceptibility to AR were comparatively analyzed. The Hardy-Weinberg's law of genetic balance verifies whether the two genotype frequencies were representative; Logistic multiple regression analysis was used to analyze the related factors affecting susceptibility of AR. Result: There were SNPs at rs7975232 locus of VDR gene, which were wild homozygote CC type, mutant heterozygote AC, and mutant homozygote AA. SNPs existed at rs2228570 locus, which were wild homozygote GG, mutant heterozygote GA, and mutant homozygote AA. The distributions of genotypes at rs7975232 and rs2228570 locus of VDR gene conformed to Hardy-Weinberg law. There was a significant difference in the distribution of rs7975232 genotype(P<0.05), and the frequency of C allele in the study group was significantly higher than that in the control group(P<0.05). There was no significant difference in genotype distribution of rs2228570 locus (P>0.05). Logistic analysis showed that CC genotype of ApaⅠwas a risk factor for AR susceptibility. Conclusion: The polymorphism of ApaⅠ(rs7975232) locus of VDR gene is correlated with AR susceptibility. CC genotype may be a susceptible factor for AR patients, but there is no significant correlation between FokⅠ polymorphism and AR. .

Abstract
This Letter reports the first extraction of individual antineutrino spectra from ^{235}U and ^{239}Pu fission and an improved measurement of the prompt energy spectrum of reactor antineutrinos at Daya Bay. The analysis uses 3.5×10^{6} inverse beta-decay candidates in four near antineutrino detectors in 1958 days. The individual antineutrino spectra of the two dominant isotopes, ^{235}U and ^{239}Pu, are extracted using the evolution of the prompt spectrum as a function of the isotope fission fractions. In the energy window of 4-6 MeV, a 7% (9%) excess of events is observed for the ^{235}U (^{239}Pu) spectrum compared with the normalized Huber-Mueller model prediction. The significance of discrepancy is 4.0σ for ^{235}U spectral shape compared with the Huber-Mueller model prediction. The shape of the measured inverse beta-decay prompt energy spectrum disagrees with the prediction of the Huber-Mueller model at 5.3σ. In the energy range of 4-6 MeV, a maximal local discrepancy of 6.3σ is observed.

Abstract
Objective: To explore the efficacy of closed negative pressure irrigation and suction device (Patent number: Z200780013509.8) in the treatment of high perianal abscess. Methods: From January 2015 to December 2016, ≥18-year-old patients with primary high perianal abscess who were treated at our department were prospectively enrolled. Exclusion criteria: (1) recurrent perianal abscess; (2) complicated with anal fistula formation; (3) preoperative, intraoperative or postoperative physical therapy, and curettage treatment, negative pressure irrigation; (4) Crohn's disease-related perianal abscess; (5) with immunosuppressive status, such as transplant recipients; (6) co-existence of malignant tumors, such as leukemia; (7) with diabetes; (8) those who could not receive long-term follow-up and were not suitable to participate in this study. According to the random number table method, the patients were randomly divided into negative pressure irrigation and suction group and routine drainage group. All patients were clearly diagnosed and the location and size of the perianal abscess were marked before surgery. These two groups were treated as follows: (1) Negative pressure irrigation and suction group: the skin was incised at a diameter of 1-2 cm at the site where the abscess fluctuated most obviously. After the abscess was removed, a closed negative pressure irrigation and suction device was installed and the pressure of -200 to -100 mmHg (1 mmHg=0.133 kPa) was maintained to keep the abscess cavity collapsed. Generally, the irrigation was stopped 5 days later or when the drainage was clear. The closed vacuum suction was maintained for 2 additional days, before the wound was sutured. (2) Conventional drainage group: conventional incision and drainage was carried out. The skin was cut at a diameter of 8 to 10 cm at the site of abscess with most obvious fluctuation. After the abscess was removed, normal saline gauze was used for dressing. Dressing was changed regularly until the wound healed. The efficacy, operative time, intraoperative bleeding, incision length, frequency of dressing change, pain index (visual analogue score, VAS score), postoperative healing time, complications, recurrence rate of perianal abscess, anal fistula formation rate were observed. The t test and χ2 test were used for comparison between the 2 groups. Results: There were both 40 patients in the negative pressure irrigation and suction group and the conventional drainage group. There were 28 males and 12 females in negative pressure irrigation and suction group with a mean age of (38.3±12.0) years and mean disease course of (6.6±2.1) days. The abscess in pelvic-rectal space accounted for 50.0% (20/40) and the mean diameter of abscess was (8.0±3.7) cm. There were 26 males and 14 females in the conventional drainage group with a mean age of (37.1±11.8) years and mean disease course of (6.4±2.5) days. The abscess in pelvic-rectal space accounted for 55.0% (22/40) and the diameter of abscess was (8.2±3.5) cm. The differences in baseline data between two groups were not statistically significant (all P>0.05). Both groups successfully completed the operation. There was no significant difference in operative time between two groups (P>0.05). As compared to conventional drainage group, intraoperative blood loss in negative pressure irrigation and suction group was less [(12.1±5.5) ml vs. (18.3±4.4) ml, t=5.606, P<0.001], incision length was shorter [(2.3±0.8) cm vs. (7.6±1.7) cm, t=17.741, P<0.001], postoperative VAS pain scores at 1-, 3-, 7-, and 14-day after operation were lower [3.7±1.4 vs. 7.6±1.8, t=10.816, P<0.001; 3.0±1.3 vs. 6.8±1.6, t=11.657, P<0.001; 2.7±0.9 vs. 5.1±1.1, t=10.679, P<0.001; 1.2±0.3 vs. 1.6±0.4, t=5.060, P=0.019], the dressing change within 7 days after operation was less (3.5±1.2 vs. 12.6±2.7, t=19.478, P<0.001), postoperative healing time was shorter [(10.4±3.0) d vs. (13.5±3.8) d, t=4.049, P<0.001] and postoperative complication rate was lower [17.5% (7/40) vs. 2.5% (1/40), χ2=5.000, P=0.025]. During follow-up of 12 to 36 (24±5) months, the recurrence rate of perianal abscess within 1 year after operation and anal fistula formation rate in negative pressure irrigation and suction group were lower than those in conventional drainage group [5.0% (2/40) vs. 20.0% (8/40), χ2=4.114, P=0.042 and 2.5% (1/40) vs. 17.5% (7/40), χ2=5.000, P=0.025, respectirely]. The one-time cure rate of negative pressure irrigation and suction group and conventional drainage group was 92.5% (37/40) and 62.5%(25/40), respectirely (χ2=10.323, P=0.001). Conclusions: The application of the negative pressure irrigation and suction device in the treatment of high perianal abscess can improve the efficiency of one-time cure, reduce postoperative pain, accelerate healing time, decrease the morbidity of postoperative complication and the rates of abscess recurrence and anal fistula formation, indicating an improvement of the treatment.

Abstract
Objective: To analyze the relationship between angiopoietin 2 (Ang2) and vascular endothelial factor and vasodilation function in hypertensive patients. Methods: Patients with new onset grade 1~2 hypertension (n=40) and healthy control group (n=25) wereenrolledprospectively. Serum Ang2 and nitric oxide (NO), nitric oxide synthase (eNOS), endothelin-1 (ET-1) were measured in both groups. Flow-mediated vasodilation (FMD) were measured in hypertensive patients. The above indicators were reviewed in hypertensive patients after antihypertensive treatment until blood pressure<140/90 mmHg. Results: Compared with the control group, serum Ang2 (P=0.049) and ET-1 (P<0.001) were significantly higher. Serum NO (P<0.001) and eNOS (P<0.001) was significantly lower in the hypertensive group. Compared with baseline, serum Ang2 (P=0.049) and ET-1 (P<0.001) were decreased significantly, meanwhile serum NO (P<0.001) and eNOS (P<0.001) were significantly increased. Serum Ang2 after antihypertensive treatment was not significantly different from that of the control group, but no statistical difference was observed in FMD after antihypertensive therapy. Correlation analysis found that serum Ang2 was positively correlated with mean arterial pressure (R=0.432, P<0.001), and negative correlated with serum NO(R=-0.374, P=0.001) and FMD (R=-0.368 0, P=0.002). Multiple linear regression found that serum Ang2 was independently associated with body mass index, mean arterial pressure, and serum NO. Conclusion: Serum Ang 2 can reflect the degree of endothelial and vasodilation impairment in hypertensive patients. Antihypertensive therapy can improve endothelial function, but whether it can restore damaged vasodilation function needs further verification.

Abstract
Objective: To study the expression and significance of Notch1-Jagged1 in nasal mucosa of allergic rhinitis (AR) mouse model in various stages and in the serum of AR patients. Methods: Thirty-six mice were divided into 3 groups: control group, basal sensitization group (OVA) and OVA/AR group, with 12 mice in each group. Allergic symptom in each group were scored after AR model establishment. HE staining method was used to observe the nasal mucosa eosinophils infiltration. ELISA was used to detect the serum level of total IgE. Flow cytometry was used to detect the change of Treg cells in each group. Western blot was used to detect the expression of Notch1 and Jagged1 in nasal mucosa. Flow cytometric bead array (CBA) was used to detect the level of Th1/Th2/Th17 cytokines in splenic lymphocytes. The serum was obtained from 50 patients with AR and 30 control volunteers in Department of Otorhinolaryngology Head and Neck Surgery, Renmin Hospital of Wuhan University from June to October 2017. ELISA was used to detect the expression of Notch1 and Jagged1. Results: Compared with the control group, the allergy symptom, the number of nasal mucosal eosinophils and the level of total IgE were not significantly different in basal sensitization group, but increased significantly in OVA/AR group (6.11±0.78 vs 0.67±0.50, 77.67±5.61 vs 10.33±0.82, (106.80±11.91) pg/ml vs (82.45±19.80) pg/ml, t value was 19.471, 34.848, 2.542, respectively, all P<0.05). Compared with the control group, the ratio of Treg cell increased in basal sensitization group but decreased in OVA/AR group ((10.29±0.47)% vs (9.28±0.16)%, (8.49±0.15)% vs (9.28±0.16)%, t value was 5.838, 4.540, respectively, all P<0.01). Compared with control group, the expression of Notch1 increased significantly both in basal sensitization group and OVA/AR group (1.04±0.05 vs 0.71±0.05, 1.83±0.10 vs 0.71±0.05, t value was 9.293, 31.363, respectively, all P<0.01); and the expression of Jagged1 only increased significantly in OVA/AR group (0.41±0.04 vs 0.21±0.01, t=13.472, P<0.01). It was found that Notch1 was positively correlated with the level of IL-6, IL-10 by Pearson test (r value was 0.98, 0.87, respectively, all P<0.01). Compared with control volunteers, the expression of Notch1 and Jagged1 increased significantly in AR group patients ((1 135.0±254.9) pg/ml vs (436.0±139.3) pg/ml, (1 200.2±401.0) pg/ml vs (559.9±124.2) pg/ml, t value was 13.99, 11.94, respectively, all P<0.01). Conclusions: The expression of Notch1 receptor and ligand increased significantly in the pathogenesis of AR. Notch1-Jagged1 may promote the occurrence and development of AR by up-regulating the expression of IL-6 and IL-10.

Abstract
We report a measurement of electron antineutrino oscillation from the Daya Bay Reactor Neutrino Experiment with nearly 4 million reactor ν[over ¯]_{e} inverse β decay candidates observed over 1958 days of data collection. The installation of a flash analog-to-digital converter readout system and a special calibration campaign using different source enclosures reduce uncertainties in the absolute energy calibration to less than 0.5% for visible energies larger than 2 MeV. The uncertainty in the cosmogenic ^{9}Li and ^{8}He background is reduced from 45% to 30% in the near detectors. A detailed investigation of the spent nuclear fuel history improves its uncertainty from 100% to 30%. Analysis of the relative ν[over ¯]_{e} rates and energy spectra among detectors yields sin^{2}2θ_{13}=0.0856±0.0029 and Δm_{32}^{2}=(2.471_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the normal hierarchy, and Δm_{32}^{2}=-(2.575_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the inverted hierarchy.

Abstract
The aim of the present study was to perform a preliminary analysis of the characterization and diversity of Y-chromosome haplotypes/haplogroups in yak of Qinghai Province, China. A total of 322 male yaks from nine populations belonging to three officially recognized breeds (Gaoyuan, Huanhu and Datong) were sampled. Animals were genotyped using six previously reported Y-SNPs present in the SRY, USP9Y, UTY, AMELY and OFD1Y genes and four new Y-SNPs in the OFD1Y gene (g.569A>C, g.578A>C, g.608G>T and g.653G>C) identified in this study. Seven Y-chromosome haplotypes (H1-H7) were identified according to the combination of the 10 Y-SNPs. H1, H2 and H6 were the most common and shared haplotypes across all yak populations/breeds. Private haplotypes H3 and H7 were detected in the Datong breed; H4 in Guoleimude, Qumalai, Qilian, Tianjun and Ganglong populations; and H5 in Qumalai of Gaoyuan breed. Haplotype clustering and network analyses inferred two haplogroups, Y1 and Y2, indicating two divergent lineages of paternal origins of Qinghai yak. The analysis of molecular variance showed a significant difference among individuals (P < 0.0001) with more than 93% of the total genetic variation present within populations, suggesting a weak genetic structure among Qinghai yak populations. The overall Y-haplotype diversity was 0.538 ± 0.028, showing a relatively high diversity in Qinghai yak. The Gaoyuan and Datong breeds had similar haplotype diversities (0.547 ± 0.030 and 0.553 ± 0.083, respectively), which were higher than that of the Huanhu breed (0.441 ± 0.098). Our results support the conservation and sustainable use of unique yak genetic resources in Qinghai.

Abstract
Objective:To explore the expression of polymeric immunoglobulin receptor in nasal polyps of patients with chronic rhinosinusitis with nasal polyps, and to investigateits relationship with the pathogenesis of nasal polyps. Method:Thirty-six specimens of nasal polyps were harvested patients were selected for the control group who had operation of nasal septal construction in the corresponding time period. The pIgR and IgA expression in nasal polyps and normal nasal inferior turbinate mucosa were detected by immunohistochemistry,and the real-time reverse transcription(RT-PCR) were used to detect the level of pIgR,IgA,RORc and Foxp3 mRNA expression in nasal polyps and normal nasal inferior turbinate mucosa. The association between pIgR mRNA and their association with the number of EOS,RORc mRNA,Foxp3 mRNA were analyzed,respectively. Result:The expression of pIgR in the nasal polyps was significantly lowerer than that in control group, and the result was statistically significant(P<0.05);Compared with nasal polyps with no eosinophils, the expression levels of pIgR in the nasal polyps with eosinophils was lower\, and the result was statistically significant(P<0.05).The expression of IgA in the nasal polyps was significantly higherthan that in control , and the result was statistically significant(P<0.05).Compared with control, the mRNA expression of pIgR and Foxp3 in the nasal polyps were significantly lower,while the expression levels of IgA mRNA and Foxp3 mRNA in the nasal polyps was significantly higher compared to controls, and the result was statistically significant(P<0.05).In nasal polyps ,pIgR mRNA expression was correlated with RORc mRNA (P<0.05,r=-0.79),and there was no correlation between pIgR mRNA and Foxp3 mRNA(P>0.05,r=0.36). Conclusion:It was proved that pIgR down-regulation play an important role in the development of nasal polyps..

Abstract
A 4-month-old girl developed convulsion in the neonatal period, which was focal motor seizures in the initial stage and later became spasm and tonic spasm. And the girl also had psychomotor retardation and recurrent pulmonary infection. Electroencephalography showed hypsarrhythmia, normal results were obtained from cranial magnetic resonance imaging, cerebrospinal fluid examination, and urine organic acid analysis, as well as the spectral analyses of blood ammonia, blood lactic acid, blood amino acids, and acylcarnitines. Gene detection revealed a de novo heterozygous mutation, c.607G>A (p.G203R) , in GNAO1. The girl was then diagnosed with GNAO1-associated early infantile epileptic encephalopathy (EIEE type 17). The seizures were well controlled by topiramate and vigabatrin, but there was no improvement in psychomotor development. She also suffered from recurrent pulmonary infection and died at the age of 12 months due to severe pneumonia. For children with unexplained early infantile epileptic encephalopathy, GNAO1 gene mutations should be considered and genetic tests should be performed as early as possible. Recurrent pulmonary infection should also be taken seriously.

Abstract
WHAT IS KNOWN AND OBJECTIVE OATP1B1 mediates the transport of a diverse range of amphiphilic organic compounds that include bile acids, steroid conjugates and hormones. This retrospective pharmacogenetic study was conducted to assess the impact of the OATP1B1 c.521T>C single nucleotide polymorphism (SNP) on the pharmacokinetics of the steroidal aromatase inhibitor drug exemestane in healthy volunteers. METHODS Exemestane (25 mg) was administered orally to 14 healthy post-menopausal women. All of the 14 subjects were sampled for pharmacokinetic (PK) analyses and retrospectively genotyped for OATP1B1 c.521T>C (rs 4149056). RESULTS AND DISCUSSION Of the 14 subjects enrolled in the study, five were carriers of the minor C allele (OATP1B1 c.521TC+CC) and the remaining nine were carriers of the OATP1B1 c.521TT genotype. PK was assessed over 8 hours post-dosing. Our results showed statistically significant differences (P=.04) in the plasma exemestane AUC0-8 between the OATP1B1 genotype groups. Our data also showed statistically significant differences (P=.04) in the plasma AUC0-8 of 17-hydroexemestane (the major biologically active metabolite) between the OATP1B1 genotype groups. WHAT IS NEW AND CONCLUSION Our data suggest that the OAPTP1B1 c.521T>C SNP may influence exemestane pharmacokinetics in humans.

Abstract
The Daya Bay experiment has observed correlations between reactor core fuel evolution and changes in the reactor antineutrino flux and energy spectrum. Four antineutrino detectors in two experimental halls were used to identify 2.2 million inverse beta decays (IBDs) over 1230 days spanning multiple fuel cycles for each of six 2.9 GW_{th} reactor cores at the Daya Bay and Ling Ao nuclear power plants. Using detector data spanning effective ^{239}Pu fission fractions F_{239} from 0.25 to 0.35, Daya Bay measures an average IBD yield σ[over ¯]_{f} of (5.90±0.13)×10^{-43} cm^{2}/fission and a fuel-dependent variation in the IBD yield, dσ_{f}/dF_{239}, of (-1.86±0.18)×10^{-43} cm^{2}/fission. This observation rejects the hypothesis of a constant antineutrino flux as a function of the ^{239}Pu fission fraction at 10 standard deviations. The variation in IBD yield is found to be energy dependent, rejecting the hypothesis of a constant antineutrino energy spectrum at 5.1 standard deviations. While measurements of the evolution in the IBD spectrum show general agreement with predictions from recent reactor models, the measured evolution in total IBD yield disagrees with recent predictions at 3.1σ. This discrepancy indicates that an overall deficit in the measured flux with respect to predictions does not result from equal fractional deficits from the primary fission isotopes ^{235}U, ^{239}Pu, ^{238}U, and ^{241}Pu. Based on measured IBD yield variations, yields of (6.17±0.17) and (4.27±0.26)×10^{-43} cm^{2}/fission have been determined for the two dominant fission parent isotopes ^{235}U and ^{239}Pu. A 7.8% discrepancy between the observed and predicted ^{235}U yields suggests that this isotope may be the primary contributor to the reactor antineutrino anomaly.

Abstract
BACKGROUND Adding exogenous compounds is an effective way to improve cell survival after cryopreservation. Carbon nanomaterials (CNMs) are novel exogenous substances with small particle size and good biocompatibility. OBJECTIVE In this work, four types of CNMs were used for the cryopreservation of Agapanthus praecox callus and their possible effects and mechanism of action were analyzed. MATERIALS AND METHODS The thermal properties of the vitrification solutions tested were detected by differential scanning calorimetry. Raman spectroscopy and transmission electron microscopy analyses were used to study the distribution of CNMs inside cells. The MDA/H2O2 contents were measured to evaluate the toxicity of CNMs to cells. RESULTS AND CONCLUSION Supplementation of PVS2 with various CNMs at different concentrations could enhance survival. The most effective concentration was 0.3 g/L C60, which increased survival by 159% compared to untreated controls and decreased the MDA and H2O2 contents. Single-walled carbon nanotubes (SWCNTs) and C60 entered callus cells. C60 was found only in mitochondria, whereas SWCNTs were located only around the cell walls.

Abstract
Searches for a light sterile neutrino have been performed independently by the MINOS and the Daya Bay experiments using the muon (anti)neutrino and electron antineutrino disappearance channels, respectively. In this Letter, results from both experiments are combined with those from the Bugey-3 reactor neutrino experiment to constrain oscillations into light sterile neutrinos. The three experiments are sensitive to complementary regions of parameter space, enabling the combined analysis to probe regions allowed by the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE experiments in a minimally extended four-neutrino flavor framework. Stringent limits on sin^{2}2θ_{μe} are set over 6 orders of magnitude in the sterile mass-squared splitting Δm_{41}^{2}. The sterile-neutrino mixing phase space allowed by the LSND and MiniBooNE experiments is excluded for Δm_{41}^{2}<0.8 eV^{2} at 95% CL_{s}.

Abstract
This Letter reports an improved search for light sterile neutrino mixing in the electron antineutrino disappearance channel with the full configuration of the Daya Bay Reactor Neutrino Experiment. With an additional 404 days of data collected in eight antineutrino detectors, this search benefits from 3.6 times the statistics available to the previous publication, as well as from improvements in energy calibration and background reduction. A relative comparison of the rate and energy spectrum of reactor antineutrinos in the three experimental halls yields no evidence of sterile neutrino mixing in the 2×10^{-4}≲|Δm_{41}^{2}|≲0.3 eV^{2} mass range. The resulting limits on sin^{2}2θ_{14} are improved by approx imately a factor of 2 over previous results and constitute the most stringent constraints to date in the |Δm_{41}^{2}|≲0.2 eV^{2} region.

Abstract
The influence of the Wenchuan earthquake on semen quality of adult male survivors is unclear. We investigated the semen quality included 673 male survivors from the worse-affected counties in the earthquake between Aug 2008 and July 2013. Semen parameters including pH, volume, concentration, motility and morphology were measured according to the World Health Organization (WHO) criteria. Kruskal-Wallis analysis of variance was used to examine the statistical differences between years, and a logistic regression was used to analyse the impacts caused by earthquake on the changes of semen quality. We found the medians (5th and 95th) were 2.5 ml (0.6-5.5) for semen volume, 59.0 × 106 ml-1 [(13.0-133.0)] × 106 ml-1 for semen concentration, 46% (13-64%) for sperm progressive motility and 3.0% (0-17.5%) for normal morphology for adult male survivors. Semen concentration, the percentage of sperm progressive motility, total motility and sperm normal morphology were all decreased in the first 3 years, and the differences among years 1, 2 and 3 were significant except the percentage of sperm progressive motility (P < 0.05). The casualties and heavy housing damage caused by earthquake had a negative effect on semen quality. The main findings will provide further diagnosis and therapy basis of male fertility by data, for affected populations in the earthquake.

Abstract
Phloem-feeding aphids cause serious damage to plants. The mechanisms of plant-aphid interactions are only partially understood and involve multiple pathways, including phytohormones. In order to investigate whether salicylic acid (SA) is involved and how it plays a part in the defense response to the aphid Macrosiphoniella sanbourni, physiological changes and gene expression profiles in response to aphid inoculation with or without SA pretreatment were compared between the aphid-resistant Artemisia vulgaris 'Variegata' and the susceptible chrysanthemum, Dendranthema nankingense. Changes in levels of reactive oxygen species, malondialdehyde (MDA), and flavonoids, and in the expression of genes involved in flavonoid biosynthesis, including PAL (phenylalanine ammonia-lyase), CHS (chalcone synthase), CHI (chalcone isomerase), F3H (flavanone 3-hydroxylase), F3'H (flavanone 3'-hydroxylase), and DFR (dihydroflavonol reductase), were investigated. Levels of hydrogen peroxide, superoxide anions, MDA, and flavonoids, and their related gene expression, increased after aphid infestation and SA pretreatment followed by aphid infestation; the aphid-resistant A. vulgaris exhibited a more rapid response than the aphid-susceptible D. nankingense to SA treatment and aphid infestation. Taken together, our results suggest that SA could be used to increase aphid resistance in the chrysanthemum.

Abstract
This Letter reports a measurement of the flux and energy spectrum of electron antineutrinos from six 2.9 GWth nuclear reactors with six detectors deployed in two near (effective baselines 512 and 561 m) and one far (1579 m) underground experimental halls in the Daya Bay experiment. Using 217 days of data, 296 721 and 41 589 inverse β decay (IBD) candidates were detected in the near and far halls, respectively. The measured IBD yield is (1.55±0.04) ×10(-18) cm(2) GW(-1) day(-1) or (5.92±0.14) ×10(-43) cm(2) fission(-1). This flux measurement is consistent with previous short-baseline reactor antineutrino experiments and is 0.946±0.022 (0.991±0.023) relative to the flux predicted with the Huber-Mueller (ILL-Vogel) fissile antineutrino model. The measured IBD positron energy spectrum deviates from both spectral predictions by more than 2σ over the full energy range with a local significance of up to ∼4σ between 4-6 MeV. A reactor antineutrino spectrum of IBD reactions is extracted from the measured positron energy spectrum for model-independent predictions.

Abstract
To further explore Y-STR INRA189 polymorphisms in the yak, and to determine the genetic differences among yak breeds, genotyping analysis of INRA189 in 102 male yak individuals from three yak breeds in Qinghai Province of China was performed. Genotyping revealed the presence of four alleles, with sizes of 149, 155, 157, and 159 bp, respectively. Of these, the 157-bp allele, which was found with the highest frequency in the three yak breeds, was the dominant allele. Interestingly, the 149-bp allele was only detected in the Gaoyuan breed, and the 159-bp allele was only found in the Huanhu and Datong breeds. Only the 157- and 155-bp alleles were found in all three yak breeds. Taking the three yak breeds as a single population, the frequency of these four alleles was 0.0294, 0.0686, 0.8628, and 0.0392, respectively. The average polymorphism information content in the three yak breeds was 0.2379, indicating that the INRA189 was a low polymorphic Y-STR marker in yak.

Abstract
We investigated the roles of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptor death receptor 5 (DR5) in the onset of acute leukemia and changes in their expression during chemotherapy. Bone marrow samples from 16 patients newly diagnosed with acute leukemia were collected before chemotherapy. Bone marrow samples from patients with non-hematologic malignancies served as the control group. Peripheral blood samples of patients with acute leukemia were also collected before chemotherapy and at 1 and 3 days after chemotherapy. Mononuclear cells in the bone marrow and peripheral blood were isolated and used to detect the expression of TRAIL and DR5 by flow cytometry. Compared with mononuclear cells from the control group, mononuclear cells from newly diagnosed patients with acute leukemia showed no significant difference in the expression of TRAIL (P > 0.05) but showed significantly increased expression of DR5 (P < 0.05). TRAIL and DR5 expression in peripheral blood mononuclear cells after chemotherapy was significantly increased compared to expression before chemotherapy (P < 0.05). Patients showing high expression of DR5 had a higher remission rate. One of the mechanisms underlying the treatment of leukemia with chemotherapy drugs may be the induction of TRAIL and DR5, which may promote apoptosis in leukemia cells. TRAIL-mediated apoptosis is regulated by DR5 expression.

Abstract
We report a new measurement of electron antineutrino disappearance using the fully constructed Daya Bay Reactor Neutrino Experiment. The final two of eight antineutrino detectors were installed in the summer of 2012. Including the 404 days of data collected from October 2012 to November 2013 resulted in a total exposure of 6.9×10^{5} GW_{th} ton days, a 3.6 times increase over our previous results. Improvements in energy calibration limited variations between detectors to 0.2%. Removal of six ^{241}Am-^{13}C radioactive calibration sources reduced the background by a factor of 2 for the detectors in the experimental hall furthest from the reactors. Direct prediction of the antineutrino signal in the far detectors based on the measurements in the near detectors explicitly minimized the dependence of the measurement on models of reactor antineutrino emission. The uncertainties in our estimates of sin^{2}2θ_{13} and |Δm_{ee}^{2}| were halved as a result of these improvements. An analysis of the relative antineutrino rates and energy spectra between detectors gave sin^{2}2θ_{13}=0.084±0.005 and |Δm_{ee}^{2}|=(2.42±0.11)×10^{-3} eV^{2} in the three-neutrino framework.

Abstract
OBJECTIVE To investigate the dynamic changes in serum histamine levels and their association with ST-segment resolution in patients with acute ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). METHODS A total of 84 consecutive STEMI patients who received primary PCI were enrolled in this study. The dynamic changes in serum histamine levels were observed from before PCI to 1 week after PCI. Factors associated with ST-segment resolution were identified by multivariate regression analysis. RESULTS The serum histamine levels of STEMI patients decreased during the first week after PCI. Multivariate regression analysis showed that the factors associated with ST-segment resolution 2 h after PCI were: the histamine level 2 h after PCI (r=-0.361, P=0.001), pain to balloon time, infarct related artery, and thrombolysis in myocardial infarction (TIMI) flow grade after PCI. CONCLUSION The higher histamine level 2 h after PCI was independently associated with poor myocardial reperfusion in STEMI patients.

Abstract
A search for light sterile neutrino mixing was performed with the first 217 days of data from the Daya Bay Reactor Antineutrino Experiment. The experiment's unique configuration of multiple baselines from six 2.9 GW(th) nuclear reactors to six antineutrino detectors deployed in two near (effective baselines 512 m and 561 m) and one far (1579 m) underground experimental halls makes it possible to test for oscillations to a fourth (sterile) neutrino in the 10(-3) eV(2)<|Δm(41)(2) |< 0.3 eV(2) range. The relative spectral distortion due to the disappearance of electron antineutrinos was found to be consistent with that of the three-flavor oscillation model. The derived limits on sin(2) 2θ(14) cover the 10(-3) eV(2) ≲ |Δm(41)(2)| ≲ 0.1 eV(2) region, which was largely unexplored.

Abstract
A measurement of the energy dependence of antineutrino disappearance at the Daya Bay reactor neutrino experiment is reported. Electron antineutrinos (ν¯(e)) from six 2.9 GW(th) reactors were detected with six detectors deployed in two near (effective baselines 512 and 561 m) and one far (1579 m) underground experimental halls. Using 217 days of data, 41 589 (203 809 and 92 912) antineutrino candidates were detected in the far hall (near halls). An improved measurement of the oscillation amplitude sin(2)2θ(13)=0.090(-0.009)(+0.008) and the first direct measurement of the ν¯(e) mass-squared difference |Δm(ee)2|=(2.59(-0.20)(+0.19))×10(-3) eV2 is obtained using the observed ν¯(e) rates and energy spectra in a three-neutrino framework. This value of |Δm(ee)2| is consistent with |Δm(μμ)2| measured by muon neutrino disappearance, supporting the three-flavor oscillation model.

Abstract
The study evaluated the safety of reclaimed water using health risk assessment and biotoxicity tests. The reclaimed water was produced from reverse osmosis and used in industrial and miscellaneous purposes. The health risk assessment was conducted based on the concentrations of detectable pollutants in reclaimed water in a hypothetical scenario. The estimated carcinogenic and non-carcinogenic risks are lower than the generally accepted level. Biotoxicity evaluation included three genotoxicity tests, a chronic toxicity test using medaka fishes, and a subchronic toxicity test using mice. The reclaimed water is not genetically toxic, and does not cause significant chronic effects on these model organisms. These results confirm the safety of using reclaimed water from municipal wastewater treatment plants.

Abstract
The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ(13) with a significance of 5.2 standard deviations. Antineutrinos from six 2.9 GWth reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470 m and 576 m) and one far (1648 m) underground experimental halls. With a 43,000 ton-GWth-day live-time exposure in 55 days, 10,416 (80,376) electron-antineutrino candidates were detected at the far hall (near halls). The ratio of the observed to expected number of antineutrinos at the far hall is R=0.940±0.011(stat.)±0.004(syst.). A rate-only analysis finds sin(2)2θ(13)=0.092±0.016(stat.)±0.005(syst.) in a three-neutrino framework.

Abstract
Plasmonic or metamaterial nanostructures are usually fabricated on rigid substrate i.e. glass, silicon. Optical functionality of such kinds of nanostructures is limited by the planar surface and thus sensitive to the incident angle of light. In this work, we demonstrated that a tri-layer flexible metamaterials working at near infrared (NIR) regime can be fabricated on transparent PET substrate using flip chip transfer (FCT) technique. FCT technique is solution-free and can also be applied to fabricate other functional nanostructures device on flexible substrate. We demonstrated NIR metamaterial device can be transformed into various shapes by bending the PET substrate.

Abstract
Surface plasmon polaritons (SPPs) modes on gold hole-array nanostructures were studied using spectroscopy ellipsometer in reflection mode. Using background free techniques in the optical ellipsometer, clear SPP bands on gold nanostructure/air interface were measured in UV-Visible-Near infrared (NIR) regime (300 nm-1800 nm). Plasmonic excitation with bandwidth of 13 nm (FWHM) was observed in reflection measurement, and it is much narrower than that observed in transmission measurement mode. In addition, the plasmonic excitation bands were characterized in both amplitude and phase domain. Theoretical analysis using reciprocal lattice vector method and rigorous coupled wave analysis (RCWA) agreed well with the experimental results. By measuring the TM and TE waves simultaneously, the spectroscopic ellipsometer provides an important method to analyze both amplitude and phase information in plasmonic nanostructures and metamaterials.

Abstract
Genetic immunization strategies have largely focused on the use of plasmid DNA with a gene gun. However, there remains a clear need to further improve the efficiency, safety, and cost of potential DNA vaccines. The gold particle-coated DNA format delivered through a gene gun is expensive, time and process consuming, and raises aseptic safety concerns. This study aims to determine whether a low-pressured gene gun can deliver noncarrier naked DNA vaccine without any particle coating, and generate similarly strong antigen-specific immunologic responses and potent antitumor effects compared with gold particle-coated DNA vaccine. Our results show that mice vaccinated with noncarrier naked chimeric CRT/E7 DNA lead to dramatic increases in the numbers of E7-specific CD8+ T-cell precursors and markedly raised titers of E7-specific antibodies. Furthermore, noncarrier naked CRT/E7 DNA vaccine generated potent antitumor effects against subcutaneous E7-expressing tumors and pre-established E7-expressing metastatic pulmonary tumors. In addition, mice immunized with noncarrier naked CRT/E7 DNA vaccine had significantly less burning effects on the skin compared with those vaccinated with gold particle-coated CRT/E7 DNA vaccine. We conclude that noncarrier naked CRT/E7 DNA vaccine delivered with a low-pressured gene gun can generate similarly potent immunologic responses and effective antitumor effects has fewer side effects, and is more convenient than conventional gold particle-coated DNA vaccine.

Abstract
Pseudomonas aeruginosa pneumonia usually results from a deficit of the innate immune system. To investigate whether inflammatory signalling by airway epithelial cells provides a pivotal line of defence against P. aeruginosa infection, we utilized two separate lines of inducible transgenic mice that express a constitutive activator of the nuclear factor kappa-B (NF-kappaB) pathway (IKTA) or a dominant inhibitor of NF-kappaB (DNTA) in airway epithelial cells. Compared with control mice, IKTA mice showed an enhanced host response to P. aeruginosa infection with greater neutrophil influx into the lungs, increased expression of Glu-Leu-Arg-positive (ELR(+)) CXC chemokines macrophage inflammatory protein-2 and keratinocyte chemoattractant (KC), superior bacterial clearance and improved survival at 24 h after infection. Neutrophil depletion abrogated the improvement in host defence identified in IKTA mice. In contrast, DNTA mice showed impaired responses to P. aeruginosa infection with higher bacterial colony counts in the lungs, decreased neutrophilic lung inflammation and lower levels of KC in lung lavage fluid. DNTA mice given recombinant KC at the time of P. aeruginosa infection demonstrated improved neutrophil recruitment to the lungs and enhanced bacterial clearance. Our data indicate that the NF-kappaB pathway in airway epithelial cells plays an essential role in defence against P. aeruginosa through generation of CXC chemokines and recruitment of neutrophils.

Abstract
Chen, Ke and Chang (1990) have presented a fuzzy forward reasoning algorithm for rule-based systems using fuzzy Petri nets. In this paper, we extend the work of Chen, Ke and Chang (1990) to present a fuzzy backward reasoning algorithm for rule-based systems using fuzzy Petri nets, where the fuzzy production rules of a rule-based system are represented by fuzzy Petri nets. The system can perform fuzzy backward reasoning automatically to evaluate the degree of truth of any proposition specified by the user. The fuzzy backward reasoning capability allows the computers to perform reasoning in a more flexible manner and to think more like people.

Abstract
In this paper, we extend the works of Chen and Horng (1996) and Itzkovich and Hawkes (1994) to present a new method for finding the inheritance hierarchies in fuzzy-valued concept-networks, where the relevant values (degrees of generalization or degrees of similarity) between concepts in a fuzzy-valued concept network are represented by fuzzy numbers. The proposed method is more flexible than the ones presented previously due to the fact that it allows the grades of similarity and the grades of generalization between concepts to be represented by fuzzy numbers rather than crisp real values between zero and one or interval values in [0,1].

Abstract
This paper presents a new method for document retrieval using fuzzy-valued concept networks, where the relevant degrees between the concepts in a fuzzy-valued concept network are represented by arbitrary shapes of fuzzy numbers. There are two kinds of relevant relationships between any two concepts in a fuzzy-valued concept network, i.e., fuzzy positive association and fuzzy negative association. The relevant matrices and the relationship matrices are used to model the fuzzy-valued concept network. The elements in a relevant matrix represent the relevant degrees between concepts. The elements in a relationship matrix represent the relevant relationships between concepts. Furthermore, ne also allow users' queries to be represented by arbitrary shapes of fuzzy numbers and to use fuzzy positive association relationship and fuzzy negative association relationship for formulating their queries for increasing the flexibility of fuzzy information retrieval systems. We also present an information retrieval method in the Internet environment based on the network-type fuzzy-valued concept network architecture.

Abstract
We report high-efficiency and high-contrast phosphorescent topemitting organic light-emitting devices (OLEDs) by employing the low reflectance p-type Si bottom anodes and the high transmittance Cs(2)CO(3)/Ag top cathodes for effective hole and electron injection. With the green electrophosphorescent material fac tris (2-phenylpyridine) iridium [Ir(ppy)(3)] doped emitting layer, the devices exhibit peak external quantum and power efficiencies of 3.5% (12 cd/A) and 4.5 lm/W, which are the highest values reported for OLEDs using Si wafers as electrodes. Moreover, these devices exhibit significantly higher contrast compared to the conventional bottom-emitting and top-emitting OLEDs with the highly reflective back electrodes.

Abstract
The stability of peptide growth factors exposed to fluids from healing surgical wounds and from nonhealing chronic wounds was examined in vitro. (125)I-Labeled transforming growth factor-beta1 or platelet-derived growth factor-BB was incubated with fluids from healing surgical wounds and fluids from venous stasis or pressure ulcers. Fluids from healing surgical wounds had no appreciable effect on the level of (125)I corresponding to intact growth factor. In contrast, incubation with fluids from several venous stasis or pressure ulcers resulted in significant degradation of these growth factors. Degradation was blocked by broad-spectrum serine proteinase inhibitors and by specific inhibitors of neutrophil elastase. Levels of elastase activity in wound fluids correlated with the ability to degrade peptide growth factors. Further comparisons showed qualitative and quantitative differences in the endogenous proteinase inhibitors, alpha2-macroglobulin and alpha1-antiproteinase. These results could explain, in part, the variable growth factor levels which have been found in chronic wounds. More importantly, the ability of some chronic nonhealing wounds to rapidly degrade exogenously added growth factors has important implications with regard to past and future clinical attempts to use peptide growth factors to treat these types of problem wounds.

No evidence for a nu(e) appearance signal was found, and we set bounds on the nu(mu) --> nu(e) oscillation parameters. At Deltam(2)=2.8 x 10(-3) eV(2), the best-fit value of the K2Knu(mu) disappearance analysis, we set an upper limit of sin(2)2theta(mue) < 0.13 at a 90% confidence level.

Abstract
Hyperglycemic response of freshwater giant prawn, Macrobrachium rosenbergii, under acute cold shock was investigated, and the involvement and stimulatory pathways of norepinephrine (NE) on induced-glycemia were further examined. Remarkable elevations in hemolymph glucose at comparable magnitude were observed in both intact and eyestalkless prawn under cold treatments, suggesting that hyperglycemic response of this species is not solely mediated through the actions of crustacean hyperglycemic hormone released from X-organ sinus gland complex on the target tissues, but NE is involved. Positive and significant correlations were noted between the hemolymph glucose titers and NE contents in both thoracic ganglia and the hemolymph, suggesting that NE plays a significant role in the hyperglycemic responses of this species under cold. Depressive effects of various adrenoceptor antagonists monitored in vivo and in vitro further suggest that the action of NE is primarily mediated through both alpha1- and beta1-adrenoceptors.

We report the result from a search for charged-current coherent pion production induced by muon neutrinos with a mean energy of 1.3 GeV. The data are collected with a fully active scintillator detector in the K2K long-baseline neutrino oscillation experiment. No evidence for coherent pion production is observed, and an upper limit of is set on the cross section ratio of coherent pion production to the total charged-current interaction at 90% confidence level. This is the first experimental limit for coherent charged pion production in the energy region of a few GeV.

Abstract
BACKGROUND Heme oxygenase (HO) is a rate-limiting enzyme of endogenetic carbon monoxide (CO) that degrades heme into carbon monoxide, bilirubin, and iron. These products have important physiologic effects: bilirubin is a potent antioxidant that can act against ischemia/reperfusion injury; there is a negative correlation between the content of HO-1 and the incidence of coronary heart disease (CHD). HYPOTHESIS This study was undertaken to investigate the changes of HO-1 in patients with CHD. METHODS Thirty-five patients with acute myocardial infarction (AMI), 40 patients with unstable angina pectoris (UAP, diagnosed by coronary angiography), and 30 patients with stable angina pectoris (AP, diagnosed by coronary angiography) were selected for the study; another 30 patients with normal coronary artery (diagnosed by coronary angiography) were selected as controls. The levels of HO-1 protein expression in monocyte and lymphocyte in the subjects were tested by immunohistochemistry and western blot. Computer picture analyzing systems were also used to measure the levels of HO-1 protein expression. RESULTS Heme oxygenase-1 protein is located in cell plasma. The levels of HO-1 protein expression in patients with CHD were significantly higher than in those without CHD (p < 0.01). There were significant differences of HO-1 expression among the three groups of patients with CHD. The group with AMI was the highest, followed by the group with UAP and finally by the group with AP. CONCLUSIONS There is a higher expression of HO-1 in patients with CHD. The levels of HO-1 protein are associated with the severity of CHD.

Abstract
The purpose of this research was to examine the relationship between burnout components and selected demographic variables in a group of intensive care unit nurses. This research hopes to heighten awareness of both intensive care nurses and hospital administrators of the importance of burnout in their work setting. A descriptive correlational study design was used to examine the extent of burnout according to selected demographic variables. Sixty-eight intensive care nurses from two hospitals and critical care courses at one university completed a demographic data form and the research questionnaire of the Maslach Burnout Inventory (MBI). Statistical analysis included non-parametric tests. Study results indicated low to moderate levels of total component scores in all intensive care nurses and on all three subscales of the assessment instrument. Results also indicated that, in this sample, younger nurses (20-29 years of age), separated and divorced nurses, and staff who work full time in ICUs were the most prone to emotional exhaustion. These research findings recommend support for ICU nurses to prevent burnout in their work setting. Further research is necessary to examine what kinds of working environments (job related stress) are effective in mitigating burnout amongst staff in the intensive care field.

Abstract
We describe a patient who experienced dystonia coincident with the administration of an i.v. contrast agent. Dystonic reactions are not well known outside of the fields of Emergency Medicine, Neurology, and Psychiatry. They have not been previously reported as a reaction to i.v. contrast material. Prompt consideration and treatment of this condition may prevent unnecessary patient discomfort and interventions.
