Abstract
Divertor detachment offers a promising solution to the challenge of plasma-wall interactions for steady-state operation of fusion reactors. Here, we demonstrate the excellent compatibility of actively controlled full divertor detachment with a high-performance (βN ~ 3, H98 ~ 1.5) core plasma, using high-βp (poloidal beta, βp > 2) scenario characterized by a sustained core internal transport barrier (ITB) and a modest edge transport barrier (ETB) in DIII-D tokamak. The high-βp high-confinement scenario facilitates divertor detachment which, in turn, promotes the development of an even stronger ITB at large radius with a weaker ETB. This self-organized synergy between ITB and ETB, leads to a net gain in energy confinement, in contrast to the net confinement loss caused by divertor detachment in standard H-modes. These results show the potential of integrating excellent core plasma performance with an efficient divertor solution, an essential step towards steady-state operation of reactor-grade plasmas.

Abstract
Objective: To observe the adverse reactions of Diphtheria, Tetanus, Acellular Pertussis and Haemophilus Influenzae Type b Combined Vaccine conjugate vaccine at the anterolateral thigh muscle, upper arm deltoid muscle and upper gluteal region. Methods: A total of 12 241 infants who were voluntarily vaccinated DTaP-Hib from April 2015 to April 2019 in Beijing were selected for the study. DTaP-Hib vaccine is recommended for 3, 4, 5 months of age for basic immunization and 18 to 24 months of age to strengthen immunization. Subjects were divided into the groups of lateral thigh muscle, the upper arm deltoid and upper gluteal region according to the actual inoculation sites. Adverse reactions were collected within 30 minutes and 7 days after each does of vaccination at different sites and compared between three groups. The incidence of adverse reactions at the three different inoculation sites was compared by Chi-square test. Results: A total of 12 241 infants and toddlers received combined DTaP-Hib and 35 027 doses of DTaP-Hib were investigated. The number and of lateral thigh muscles, upper arm deltoids and gluteal muscles were 3 461 infants and 11 129 doses, 2 659 infants and 7 957 doses, 6 121 infants and 15 941 doses respectively. A total of 2 489 adverse reactions occurred. The incidence of adverse reactions was 7.11%. The incidence of adverse reactions in deltoid muscle of upper arm was 9.69%(771 doses), which was higher than that in gluteal muscle (7.58%, 1 211 doses) and anterolateral muscle of thigh (4.56%, 507 doses). The incidence of mild, moderate and severe adverse reactions in the upper arm deltoid group were higher than those in the other two groups. The incidence rates were 4.85% (386 doses), 3.77% (300 doses) and 1.07% (85 doses) respectively. The differences between groups were statistically significant(P<0.001). The total adverse reactions of the three doses of basic immunization and the fourth dose of enhanced immunization had the same trend in different parts. The incidence of adverse reactions was in the order of the upper arm deltoid injection, upper gluteal injection and lateral thigh muscle injection from high to low. The differences were statistically significant (P<0.001). Conclusion: The incidence of adverse reactions of DTaP-Hib vaccination in three different sites was low, which confirmed that the DTaP-Hib vaccination got expected safety regardless of the sites of inoculation. The lateral femoral muscle group had the lowest incidence of adverse reactions, hence it should be preferred as the inoculation site of DTaP-Hib vaccination.

Abstract
Objective: To understand the molecular characteristics and correlation among isolated strains of Brucella melitensis (BM) so as to improve the strategies on prevention and control of the disease in Jiangxi province. Methods: A total of 25 strains of BM isolated from human in 17 counties of Jiangxi province were analyzed by multiple locus variable-number tandem repeat analysis (MLVA) method. Results: A total of 25 strains of BM were classified into 24 independent genotypes with similarities between 67.00% and 100.00% and Simpson index between 0.000 and 0.773. There were 3 genotypes in MLVA8, including 60.00% (15/25) as 42 genotype, 32.00% (8/25) as 43 genotype, and 8.00% (2/25) as 63 genotype, respectively. There were 7 genotypes in MLVA11 identified, with 116 genotype and 125 genotype the main genotypes, accounting for 56.00% (14/25) of all the identified strains. Conclusions: Genes from all the 25 strains of BM that isolated from human being were with high genetic diversities, and various, genotypes. However, no obvious epidemiological correlation was noticed among these strains, indicating the complexity of the source of infection on Brucella in Jiangxi province.

Abstract
Multiple approaches utilizing viral and DNA vectors have shown promise in the development of an effective vaccine against HIV. In this study, an alternative replication-defective flavivirus vector, RepliVax (RV), was evaluated for the delivery of HIV-1 immunogens. Recombinant RV-HIV viruses were engineered to stably express clade C virus Gag and Env (gp120TM) proteins and propagated in Vero helper cells. RV-based vectors enabled efficient expression and correct maturation of Gag and gp120TM proteins, were apathogenic in a sensitive suckling mouse neurovirulence test, and were similar in immunogenicity to recombinant poxvirus NYVAC-HIV vectors in homologous or heterologous prime-boost combinations in mice. In a pilot NHP study, immunogenicity of RV-HIV viruses used as a prime or boost for DNA or NYVAC candidates was compared to a DNA prime/NYVAC boost benchmark scheme when administered together with adjuvanted gp120 protein. Similar neutralizing antibody titers, binding IgG titers measured against a broad panel of Env and Gag antigens, and ADCC responses were observed in the groups throughout the course of the study, and T cell responses were elicited. The entire data demonstrate that RV vectors have the potential as novel HIV-1 vaccine components for use in combination with other promising candidates to develop new effective vaccination strategies.

Abstract
We report on the first direct comparisons of microtearing turbulence simulations to experimental measurements in a representative high bootstrap current fraction (f_{BS}) plasma. Previous studies of high f_{BS} plasmas carried out in DIII-D with large radius internal transport barriers (ITBs) have found that, while the ion energy transport is accurately reproduced by neoclassical theory, the electron transport remains anomalous and not well described by existing quasilinear transport models. A key feature of these plasmas is the large value of the normalized pressure gradient, which is shown to completely stabilize conventional drift-wave and kinetic ballooning mode instabilities in the ITB, but destabilizes the microtearing mode. Nonlinear gyrokinetic simulations of the ITB region performed with the cgyro code demonstrate that the microtearing modes are robustly unstable and capable of driving electron energy transport levels comparable to experimental levels for input parameters consistent with the experimental measurements. These simulations uniformly predict that the microtearing mode fluctuation and flux spectra extend to significantly shorter wavelengths than the range of linear instability, representing significantly different nonlinear dynamics and saturation mechanisms than conventional drift-wave turbulence, which is also consistent with the fundamental tearing nature of the instability. The predicted transport levels are found to be most sensitive to the magnetic shear, rather than the temperature gradients more typically identified as driving turbulent plasma transport.

Abstract
Objective:To analyze the relationship and mechanism of mast cell with allergic rhinitis and nasal polyps. Method:From January 2018 to June 2018, all the inpatients in Otolaryngology Department were examined by nasal endoscopy and CT before operation. They were divided into three groups: 30 patients with allergic rhinitis(AR group) and 30 patients with nasal polyps(NP group) as the experimental group; 30 patients with nasal septum correction after partial inferior turbinectomy alone as the control group(N group). Clinical data, peripheral blood and nasal mucosa were collected. The percentage of eosinophils in peripheral blood was detected by automatic hematology analyzer. The levels of anti-IgE antibody, FcεRIα and anti-FcεRIα antibody in serum were detected by ELISA. The levels of serum IgE were detected by velocity scattering turbidimetry. HE was used to observe the histopathological changes in the three groups. Immunohistochemical method was used to analyze the expression of tryptase and FcεRIα in the experimental group and the control group. Result:The percentage of eosinophils, IgE, anti-IgE antibody, FcεRIα and anti-FcεRIα antibodies in AR group were significantly higher than those in control group(P<0.05); the percentage of eosinophils, FcεRIα and anti-FcεRIα antibodies in NP group were significantly higher than those in healthy control group(P<0.05). There was no significant difference in IgE and anti-IgE antibodies among three groups(P>0.05). The eosinophil percentage, IgE and anti-IgE antibody levels in AR group were significantly higher than that in NP group(P<0.05); there were no differences in FcεRIα and anti-FcεRIα antibody levels between AR group and NP group(P>0.05); There was no significant difference in eosinophil infiltration between the two groups; The brown tryptase-positive mast cells and FcεRIα-positive mast cells were found in the submucosa and interstitium of nasal mucosa. Conclusion:The high expression of FcεRIα and its antibody in the serum of patients with allergic rhinitis and nasal polyps indicated that this antibody system was involved in the occurrence and development of allergic rhinitis and nasal polyps. Local allergy with mast cells as the core might play an important role in the occurrence and development of nasal polyps. The possible role of mast cells in the formation of nasal polyps and the specific mechanism deserve further study.

Abstract
Abstract
Background
Atherosclerotic plaque formation and rupture is the primary cause for cardiovascular diseases. It's known that cell death and inflammation are crucial processes leading to atherosclerosis, which involves an important role of histamine. The aim of the present study is to determine the function of signal transducer and activator of transcription 6 (STAT6) in histamine-induced macrophage pyroptosis and plaque instability.
Methods
We constructed APOE/STAT6 double knock out (DKO) mice via hybridization of ApoE−/− and STAT6−/− mice. 20 ApoE−/− mice (control) and 20 DKO mice were challenged with high-fat diet for 12 weeks while 10 in each group were intraperitoneally infused with histamine (400ug/kg) every other day. The extent and instability of atherosclerotic plaque were determined by oil-red staining, HE staining, immunofluorescence staining and electron microscopy. Changes in subsets of immune cells were evaluated by flow cytometry. Plasma cytokines were assessed by ELISA. Microarray analysis was applied to detect gene expressions while Western blot and real-time PCR was used to assess gene expression levels.
Results
Morphology studies revealed that histamine could promote plaque formation and vulnerability in ApoE−/− mice, whereas this effect was inhibited in DKO mice. FACS data showed that histamine injection could increase CD11b+Ly6Chigh M1 macrophages differentiation and pyroptosis and facilitate foam cells formation in ApoE−/− mice, which was also inhibited in DKO mice. Microarray analysis and in vitro studies exhibited that histamine could induce the up-regulation of pyrotosis-related proteins such as NLRP3, caspase-1 and MMPs via a STAT6-dependent pathway to promote macrophage pyroptosis and foam cell formation.
Conclusions
We have characterized a novel role for histamine in modulating atherosclerotic lesion development and progression. Moreover, our work have figured out the detailed mechanisms by which histamine modulates the pyroptosis of macrophages and the progress of unstable atherosclerotic plaques. We envision that this study may provide several potential therapeutic targets benefit for atherosclerosis treatment.

Abstract
OBJECTIVES To provide a novel assay to detect incomplete antibodies in the crossmatching test. BACKGROUND There is a requirement in China that both major and minor crossmatch tests are required. Among all methods of crossmatching, the tube anti-human globulin test requires tedious washing steps and is time-consuming, whereas the microcolumn gel immunoassay anti-human globulin test is susceptible to sample quality. METHODS The process of the microplate hydrogel immunoassay anti-human globulin test involves the use of our patented hydrogel chromatography medium and U-bottom microplates pre-coated with goat anti-human globulin (AHG). A mixture of red blood cells (RBCs) and serum is centrifuged through the hydrogel under precise conditions. In incompatible reactions, the sensitised RBCs are captured by the pre-coated AHG and form a layer over the bottom of the well, whereas in compatible reactions, the unbound RBCs form a button at the bottom of the well. The sensitivity of this new approach and the performance when testing old specimens were evaluated. RESULTS This approach was more convenient and slightly more sensitive than the tube anti-human globulin test and was superior to the microcolumn gel immunoassay when testing old specimens. CONCLUSION In general, this assay is suitable for the routine clinical use of crossmatching to detect incomplete antibodies.

Abstract
OBJECTIVE To determine whether the combination of prostaglandin E2 (PGE2) and EP2, the subtype receptor of PGE2, could trans-activate the epidermal growth factor receptor (EGFR). PATIENTS AND METHODS In this experiment, we selected epithelial cells from normal esophageal mucosa as the negative control group, and the ESCC EC109 and TE-1 cell strain as the observation group. Real-time PCR and Western-blotting were used to detect the expression of EP2, EGFR and phosphorylated EGFR (p-EGFR). The pre-treatment of ESCC cell strains was carried out using Butaprost (special agonist of PGE2 and EP2) and RNAi of EP2, and we observed the expression of EP2, EGFR, and p-EGFR. WST-8 (CCK-8) was applied for the detection of the cell proliferation rate. The transwell invasion experiment was conducted for the detection of the invasion capability of cells. The expression of MMP-9 (matrix metalloproteinase-9), VEGF (vascular endothelial growth factor), pro-inflammatory factors (IL-6 and TNF-α) in the cell supernatant were detected using ELISA. RESULTS The high mRNA and protein expression of EP2, EGFR, and p-EGFR were found in the EC109 and TE-1 cell strains in the observation group, which were higher than those in the control group (p < 0.05). After the intervention of PGE2, EP2 expression was decreased and the p-EGFR expression was increased (p < 0.05). There was no variation found in the expression of EGFR (p > 0.05). After cells were intervened using Butaprost, the expressions of EP2 and p-EGFR were increased (p < 0.05), and there were no changes identified in the expression of EGFR (p > 0.05). After the intervention of RNAi, the expression of EP2 and p-EGFR was decreased (p < .05), and no changes were identified in the expression of EGFR (p > 0.05). After the intervention of PGE2 and Butaprost, great increases were seen in the cell proliferation rate, invasion capability, and the expression of MMP-9, VEGF, IL-6, and TNF-α in EC109 and TE-1 cell strains (p < 0.05), however, the intervention of RNAi could reduce above indexes (p < 0.05). CONCLUSIONS Through cell experiments, we verified that the combination of prostaglandin E2 (PGE2) and EP2, the subtype receptor of PGE2, could trans-activate the epidermal growth factor receptor (EGFR) to regulate the proliferation and invasion capability of esophageal squamous cell carcinoma (ESCC) cells, and secrete and express multiple cytokines, thus discovering the pathological mechanism of inflammation to carcinoma transition in the occurrence of ESCC, and providing the experimental evidence for the search of new target in the treatment of ESCC. ESCC cells can highly express the receptor subtype EP2 of PGE2 that can transactivate the EGFR, through which PGE2 is involved in the transition mechanism from inflammation to cancer.

Abstract
OBJECTIVE To explore the influential factors of kidney transplant patients' self-management, especially psychosocial variables. STUDY DESIGN This was a cross-sectional study. METHODS Questionnaires were administered to patients with the assistance of our team members to gather sociodemographic information, medical characteristics, self-management, social support, depression, and flourishing. RESULTS The study included 483 patients, 64.4% of whom were male. The score index of the total self-management scale was 81.95% and the "social psychology" dimension had the lowest index, at 75.63%. Higher scores for flourishing, shorter length of post-renal transplantation, more social support, lower body mass index, being female, and being employed were proved to be determinants of better self-management, and flourishing was identified as having the greatest influence. Some other indicators were also related to patients' self-management, particularly age, residence, income, hypertension, renal function, and depression. CONCLUSION The overall self-management of KT patients was middling, and the status of psychology management was not optimistic. This emphasized the importance of psychological intervention. For further exploration, flourishing was identified as contributing to better self-management, which implied that strengthening this factor could be another method of improving self-management, except that involves enhancing of social support and reducing depression. Age was also found to have differing degrees of influence on KT patients' self-management, which implies that younger patients should receive more support in self-management.

Abstract
Background and purpose The aim of this study was to retrospectively investigate clinical and neuroimaging characteristics in the largest sample size of patients with corpus callosum infarction to date and then to follow up these patients for 1 year to clarify the prognosis of this rare stroke entity. Methods A total of 127 patients with acute callosal infarction out of 5584 acute ischaemic stroke patients were included in this study. The recruited patients were divided into a pure callosal infarction group and a complex callosal infarction group (coupled with other infarct locations simultaneously), and clinical and neuroimaging features were analyzed. Some of the patients were followed up for 1 year to evaluate recurrence rate and mortality. Results The incidence of acute callosal infarction was 2.3%. Most patients presented with advanced neurological dysfunction with or without mild to moderate motor or sensory disorders on admission. The negative rate of computed tomography scan was still 76.4% even at >24 h after onset. Large‐artery atherosclerosis was the most common etiological type. Compared with complex callosal infarction, the pure callosal infarction group had more mental disorders (P = 0.030). Compared with common basal ganglia infarction, the pure callosal infarction group had better short‐term recovery (P = 0.016) but higher 1‐year mortality (P = 0.037). Age and mental disorders were independent risk factors for death in callosal infarction. Conclusions Callosal infarction is a white matter stroke that occurs with low incidence. Elderly patients with vascular risk factors showed sudden mental or cognitive disorders and callosal infarction could not be excluded. More attention should be paid to the early diagnosis and secondary prevention of callosal infarction because of its poor long‐term outcome.

Abstract
The objective of this study was to determine the effects of live yeast (LY) or yeast derivatives (YD) on gas production (GP), dry matter (DM) disappearance (DMD), fermentation characteristics, and microbial profiles in batch culture. The study was a completely randomized design with a factorial arrangement: 2 media pH × 5 yeasts × 4 dosages. An additional treatment of monensin (Mon) was added as a positive control for each pH level. Media pH was low (5.8) and high (6.5); the yeasts were three LY (LY1-3) and two YD (YD4-5); and doses were 0, 4 × 106, 8 × 106, and 1.6 × 107 cfu mL−1 for LY and 0, 15, 30, and 60 mg bottle−1 for YD. Substrate consisted of 10% silage and 90% concentrate (DM basis) and samples were incubated for 24 h. Media pH of 6.5 vs. 5.8, increased (P < 0.01) GP, DMD, and volatile fatty acid (VFA) concentrations but decreased (P < 0.01) NH3-N concentration and copy numbers of Ruminococcus albus, Ruminococcus flavefaciens, and Selenomonas ruminantium. Increasing dose of LY2 linearly (P < 0.05) increased DMD. Total VFA concentration was greater with LY2 (P < 0.01) than LY3 and YD5 at pH 6.5. Overall, adding yeast products improved (P < 0.05) DMD at pH 5.8, and increased VFA concentration compared with Mon. These results indicate that in vitro GP and DMD of a high-grain diet varied with source and dose of yeast supplementation. Some yeast products have the potential to improve fermentation of feedlot diets when supplemented at appropriate doses.

Abstract
BACKGROUND Recent upper respiratory tract infection (URI) is associated with increased incidence of perioperative complications in children undergoing open heart surgery. As a result, surgery is often postponed. However, the effect of recent URI on the incidence of perioperative complications in children undergoing therapeutic cardiac catheterisation is unknown. We investigated the perioperative outcomes of congenital heart disease (CHD) children with recent URI who underwent elective therapeutic catheterisation. METHODS We prospectively included children treated for CHD. Before surgery, parents or legal guardians were interviewed to complete a questionnaire on the child's demographics, history of asthma and passive smoking, and URI symptoms. Recorded perioperative respiratory adverse events (PRAEs) included laryngospasm, bronchospasm, breath holding, oxygen desaturation, and severe cough. Information on postoperative dysphoria, fever, copious sputum, and vomiting was obtained by telephone 24 h after surgery. RESULTS Of 363 included children, 169 had recently (within 2 weeks) had a URI. The URI did not affect the incidence of laryngospasm, bronchospasm, breath holding, fever, or vomiting. The incidence of desaturation, severe cough, dysphoria, and copious sputum were significantly increased. Independent risk factors for PRAEs in children with a recent URI included age, passive smoking, and presence of rhinorrhoea or moist cough. The lengths of stay in the hospital and intensive care unit were not significantly different between groups. CONCLUSION Although recent URI increased the incidence of PRAEs in children undergoing therapeutic cardiac catheterisation, most CHD patients with recent URI can undergo elective therapeutic cardiac catheterisation without serious adverse events or prolonged hospitalisation.
