Abstract
Objective: To retrospectively analyze the efficacy and safety of modified cell infusion method in reducing the incidence of febrile non-hemolytic transfusion reaction (FNHTR). Methods: A total of 69 patients were enrolled in the clinical trial of CD(19) chimeric antigen receptor T (CAR-T) cell treatment from February 2017 to October 2018. Study group received the modified cell infusion method, that 1×10(6) CAR-T cells were re-suspended in 2 mg human serum albumin with total volume of 20 ml and injected intravenously. The control group was intravenously administrated with CAR-T cell in 100 ml normal saline. The incidence of FNHTR, cytokine releasing syndrome (CRS) grade, cytokine level and efficacy were compared. Results: (1)The incidence of FNHTR in the study group was 21.1%, significantly lower than that in the control group (71%)(P=0.000). (2)There was no statistical difference in cell proliferation between the study group and the control group on day 4, 7, 14 and 21 after CAR-T cell infusion (P=10.223, 3.254, 5.551, 7.605). (3)There was no statistical difference in CRS grading between the study group and the control group (P=0.767). There was no statistical difference in the levels of interleukin 2 receptor (IL-2R), IL-6, tumor necrosis factor (TNF)-α between the two groups. (4)The C-reaction protein (CRP) level of the study group was lower than that of the control group on day 4 and 7 (P=0.026, 0.007). (5)There was no statistical difference of response rates in acute lymphocytic leukemia (ALL) and non-Hodgkin lymphoma (NHL) patients between the two groups (P(ALL)=0.842; P(NHL)=0.866). Conclusion: The modified cell infusion method in CD(19) CAR-T cell treatment reduces the incidence of treatment-related FNHTR. It does not affect the proliferation of CAR-T cells in vivo, the grading of CRS and the response rates.

Abstract
Anti-CD19 chimeric antigen receptor T cell (CAR-T) therapy has changed the typical outcomes of relapsed/refractory B-cell leukemia and lymphoma. However, treatment effectiveness for patients with relapsed/refractory B-cell non-Hodgkin lymphoma has been less satisfactory compared with patients with B-cell acute lymphoblastic leukemia. The present study described a case of refractory follicular lymphoma. A high expression of programmed cell death 1 (PD-1) was measured on CD3+ T cells (80.90%) in peripheral blood samples obtained from the patient enrolled in this study, indicating that treatment with autologous CAR-T 19 cell therapy may not be successful. Therefore, a therapy regimen consisting of CAR-T 19 cells in combination with a reduced dose of nivolumab (1.5 mg/kg) for PD-1 blockade was used. A low dose of PD-1 blockade therapy was used to reduce the adverse effects associated with the combination of a PD-1 inhibitor and CAR-T 19 cells. This salvage therapy resulted in remission that lasted for >10 months.

Abstract
Lipopeptides possess excellent broad spectrum antimicrobial activity. Different lipopeptides have their own unique chemical structures, properties and biological activities. Quantitative analysis of the lipopeptides iturin and surfactin and their homologues produced by Bacillus natto NT-6 subjected to different culture media, shaking speed of rotary shaker, and liquid and solid fermentation methods was conducted using LC-MS. For iturins, liquid-state fermentation in Landy medium at a shaking speed of 160 r min-1 was the most suitable for maximal homologue production. Addition of 0.4% attapulgite powder increased production by 1.92-fold; activated carbon significantly reduced production. For surfactin homologues, solid-state fermentation in potato dextrose broth medium at shaking speed > 160 r min-1 was the best. Addition of 0.4% attapulgite powder increased production by 1.96-fold; activated carbon had no effect. Thus it is clear that fermentation conditions can be manipulated to maximize iturin and surfactin production.

Abstract
Fly ash generated from coal-fired power plants is a source of potential pollutants, but can be used as a soil ameliorant to increase plant biomass and yield in agriculture. However, the effects of fly ash soil application on plant biomass and the accumulation of both nutrient and toxic elements in plants remain unclear. Based on 85 articles, we conducted a comprehensive meta-analysis to evaluate changes in plant biomass and concentrations of 21 elements in plants in response to fly ash application. These elements included macro-nutrients (N, P, K, Ca, and S), micro-nutrients (B, Co, Cu, Fe, Mn, Mo, Ni, and Zn), and metal(loid)s (Al, As, Cd, Cr, Pb, and Se). Overall, fly ash application decreased plant biomass by 15.2%. However, plant biomass was enhanced by fly ash application by 11.6-29.2% at lower application rates (i.e. <25% of soil mass), and decreased by 45.8% at higher application rates (i.e. 50-100%). Belowground biomass was significantly reduced while yield was enhanced by fly ash application. Most of the element concentrations in plants were enhanced by fly ash application, and followed a descending order with metal(loid)s > micro-nutrients > macro-nutrients. Concentrations of elements tended to increase with an increase in fly ash application rate. Our syntheses indicated that fly ash should be applied at less than 25% in order to enhance plant biomass and yield but avoid high accumulations of metal(loid)s.

Abstract
In this paper, accurate trajectory tracking control problem of a quadrotor with unknown dynamics and disturbances is addressed by devising a hybrid finite-time control (HFTC) approach. An adaptive integral sliding mode (AISM) control law is proposed for altitude subsystem of the quadrotor, whereby underactuated characteristics can decoupled. Backstepping technique is further deployed to control the horizontal position subsystem. To exactly attenuate external disturbances, a finite-time disturbance observer (FDO) combining with nonsingular terminal sliding mode (NTSM) control strategy is constructed for attitude subsystem, and thereby achieve finite-time stability. Using the compounded control scheme, trajectory tracking errors can be stabilized rapidly. Simulation results and comprehensive comparisons show that the proposed HFTC scheme has remarkably superior performance.

Abstract
The complete genome sequence of Bacillus velezensis type strain CMT-6 is presented for the first time. A comparative analysis between the genome sequences of CMT-6 with the genome of Bacillus amyloliquefaciens DSM7T, B. velezensis FZB42, and Bacillus subtilis 168 revealed major differences in the lipopeptide synthesis genes. Of the above, only the CMT-6 strain possessed an integrated synthetase gene for synthesizing surfactin, iturin, and fengycin. However, CMT-6 shared 14, 12, and 10 other lipopeptide-producing genes with FZB42, DSM7T, and 168 respectively. The largest numbers of non-synonymous mutations were detected in 205 gene sequences that produced these three lipopeptides in CMT-6 and 168. Comparing CMT-6 with DSM7T, 58 non-synonymous mutations were detected in gene sequences that contributed to produce lipopeptides. In addition, InDels were identified in yczE and glnR genes. CMT-6 and FZB42 had the lowest number of non-synonymous mutations with 8 lipopeptide-related gene sequences. And InDels were identified in only yczE. The numbers of core genes, InDels, and non-synonymous mutations in genes were the main reasons for the differences in yield and variety of lipopeptides. These results will enrich the genomic resources available for B. velezensis and provide fundamental information to construct strains that can produce specific lipopeptides.

Abstract
As an aquatic pathogen widely present in aquatic food, Vibrio parahaemolyticus causes outbreaks of gastroenteritis across the globe. Virulence factors of V. parahaemolyticus increases with the amount of spoilage in aquatic organisms including shrimp, but mechanisms regulating its virulence factors are not well understood. In this study, five spoilage bacteria isolated from shrimp were investigated for their regulatory effects on the virulence factors including haemolysin and biofilm of V. parahaemolyticus. Among these isolates, Shewanella putrefaciens induced haemolytic activity in V. parahaemolyticus in a time-dose-temperature-dependent manner and we found the main component responsible for this effect to be the supernatant or cell-free extract of S. putrefaciens. Total haemolytic activity, expression of the thermostable direct haemolysin gene tdh and biofilm production of V. parahaemolyticus were significantly up-regulated by S. putrefaciens, but also by deletion of quorum-sensing luxM or luxS gene of V. parahaemolyticus. However, this regulation by S. putrefaciens was significantly impaired by deletion of the luxM gene, but not by deletion of the luxS gene. Further study showed that S. putrefaciens exhibited a strong degradation ability on the signalling molecule acylated homoserine lactone (AHL) synthesised by the LuxM enzyme. This study revealed a novel virulence regulatory mechanism that S. putrefaciens can significantly increase the virulence factors of V. parahaemolyticus via interfering with the luxM- type quorum-sensing signalling pathway through its AHL-degradation ability.

Abstract
CD19 chimeric antigen receptor (CAR) T cell therapy has changed the outcomes of relapsed/refractory B‑cell leukemia and lymphoma. However, its efficacy in patients with relapsed/refractory non‑Hodgkin lymphoma (NHL) has been less impressive compared with that in patients with acute lymphoid leukemia. Furthermore, immune checkpoints have a critical role in the immune system. Several clinical trials have confirmed the dramatic effects of programmed death‑1/programmed death‑ligand 1 (PD‑1/PD‑L1) inhibitors in numerous malignancies, but the immune‑associated adverse events of PD‑1/PD‑L1 inhibitors may occur in a number of systems. The aim of the present study was to investigate the combination of CD19 CAR‑T cells with a reduced dose of PD‑1 inhibitor. This method is expected to overcome the side-effects of PD‑1 inhibitors, while maintaining therapeutic efficacy. The findings demonstrated that a reduced dose of PD‑1 inhibitor did not affect the transfection rate, proliferation rate or cytokine secretion of CD19 CAR‑T cells. An interesting finding of the present study was that the number of PD‑1‑positive cells CAR‑T cells, measured by flow cytometry, declined when they were cultured in vitro, but returned to high levels with gradual prolongation of the co‑culture time of CD19 CAR‑T cells with lymphoma cells; however, there was no change in the mRNA expression of T cells and CAR‑T cells during this process. This phenomenon may be one of the reasons why the curative effect of CAR‑T cells on B‑cell lymphoma is unsatisfactory compared with B‑cell leukemia. The synergistic effect of a reduced‑dose PD‑1 inhibitor combined with CD19 CAR‑T cells from T cells highly expressing PD‑1 was confirmed in a mouse trial. Mice in the combined treatment group achieved the longest survival time. In this group, the proportion of CAR‑T cells and the level of interleukin‑6 were higher compared with those in the CAR‑T cell group. In conclusion, a reduced dose of a PD‑1 inhibitor combined with CD19 CAR‑T cells appears to be a promising treatment option for relapsed/refractory B‑NHL exhibiting high PD‑1 expression by T cells. This method may achieve good clinical efficacy while reducing the side-effects of PD‑1 inhibitors.

Abstract
The fundamental understanding of electrocatalytic reaction process is anticipated to guide electrode upgradation and acquirement of high-performance vanadium redox flow batteries (VRFBs). Herein, a carbon fiber prototype system with a heteroatom gradient distribution has been developed with enlarged interlayer spacing and a high graphitization that improve the electronic conductivity and accelerate the electrocatalytic reaction, and the mechanism by which gradient-distributed heteroatoms enhance vanadium redox reactions was elucidated with the assistance of density functional theory calculations. All these contributions endow the obtained electrode prominent redox reversibility and durability with only 1.7% decay in energy efficiency over 1000 cycles at 150 mA cm-2 in the VRFBs. Our work sheds light on the significance of elaborated electrode design and impels the in-depth investigation of VRFBs with long service life.

Abstract
HB-EGF, a member of the EGF superfamily, plays important roles in development and tissue regeneration. However, its functions in skeletal stem cells and skeleton development and growth remain poorly understood. Here, we used the Cre/LoxP system to ablate or express HB-EGF in Dermo1+ mesenchymal stromal cells and their progenies, including chondrocytes and osteoblast lineage cells, and bone marrow stromal cells (BMSCs). Dermo1-Cre; HB-EGFf/f mice only showed a modest increase in bone mass, whereas Dermo1-HB-EGF mice developed progressive chondrodysplasia, chondroma, osteoarthritis-like joint defects, and loss of bone mass and density, which were alleviated by treatment with EGFR inhibitor AG1478. The cartilage defects were recapitulated in chondrocyte-specific HB-EGF overexpression (Col2-HB-EGF) mice with a lesser severity. Dermo1-HB-EGF mice showed an increase in proliferation but defects in differentiation of chondrocytes and osteoblasts. HB-EGF promoted BMSC proliferation via the Akt1 and Erk pathways but inhibited BMSC differentiation via restraining Smad1/5/8 activation. However, Dermo1-HB-EGF mice showed normal osteoclastogenesis and bone resorption. These results reveal an important function of autocrine or paracrine HB-EGF in mesenchymal stromal cell proliferation and differentiation and suggest that EGF signaling needs to be tightly controlled to maintain bone and articular cartilage integrity. © 2018 The Authors.

Abstract
Soil stores a substantial proportion of carbon (C), making it the greatest terrestrial C pool and pivotal to stabilizing the global climate system. Rainfall amounts and regimes have been changing in many places, but effects of precipitation changes on soil organic C (SOC) stabilization are not completely understood. Considerable attention has been focused on the consequences of changes in rainfall amounts, with rainfall regimes having been less studied. This study was conducted in a tropical climax forest to clarify the effects of rainfall changes on SOC fractions, with permanganate oxidation and density fractionations employed to divide the labile and non-labile SOC fractions. Two rainfall manipulation treatments, i.e., increased rainfall frequency with the total rainfall amount unchanged (IRF) and decreased rainfall amount by 50% with rainfall frequency unaltered (DRA), were conducted for two years, with ambient rainfall (AR) as the control. As a result, the IRF treatment increased the SOC concentration that mainly originated from increases in the non-labile SOC content. Relative to the AR control, the DRA treatment did not change the total SOC concentration although the labile SOC concentration increased. This typically is due to a small proportion of the labile fraction to the total SOC content. Our results suggest that this water-rich mature forest is resistant to rainfall amount changes to a great extent (e.g., decrease of 50% as in the present study) from the SOC stabilization perspective, while changes in rainfall frequency could exert more notable effects.

Abstract
Vanadium redox flow batteries (VRFBs) are receiving increasing interest in energy storage fields because of their safety and versatility. However, the electrocatalytic activity of the electrode is a pivotal factor that still restricts the power and cycling capabilities of VRFBs. Here, a hierarchical carbon micro/nanonetwork (HCN) electrode codoped with nitrogen and phosphorus is prepared for application in VRFBs by cross-linking polymerization of aniline and physic acid, and subsequent pyrolysis on graphite felt. Due to the hierarchical electron pathways and abundant heteroatom active sites, the HCN exhibits superior electrocatalysis toward the vanadium redox couples and imparts the VRFBs with an outstanding energy efficiency and extraordinary stability after 2000 cycles at 250 mA cm-2 and a discharge capacity of 10.5 mA h mL-1 at an extra-large current density of 400 mA cm-2. Such a micro/nanostructure design will force the advancement of durable and high-power VRFBs and other electrochemical energy storage devices.

Abstract
BACKGROUND Tumor immunotherapy with chimeric antigen receptor-T cells (CAR-T) is a promising new treatment for B-cell malignancies and has produced exciting results. However, cytokine release syndrome (CRS) is the most significant toxicity associated with this treatment and can be life-threatening. CASE PRESENTATION A 23-year-old male patient had been diagnosed with relapsed and refractory B-cell acute lymphocytic leukemia. The patient was recruited into our CAR-T clinical trial, and 1 × 106/kg of engineered anti-CD19 CAR-T cells was administered. After infusion of CAR-T cells (day 0), the patient underwent a typical CRS reaction, with increases in fever, muscle soreness, and inflammatory cytokines. He was treated with antiallergic and antipyretic drugs, glucocorticoids, and tocilizumab (4 mg/kg, days 3 and 5). However, CRS was not under control, and his condition rapidly deteriorated. He was transferred to the intensive care unit, where dexamethasone 10 mg q6h was administered, and plasma exchange was performed, with 3,000 mL of plasma replaced by fresh frozen plasma per day for 3 consecutive days. His symptoms gradually improved, and the CRS-related symptoms were relieved. Additionally, a bone marrow smear showed no lymphoblast cells, and minimal residual disease was negative on day 28. The patient was eventually discharged in a normal condition. CONCLUSIONS CRS is caused by an exaggerated systemic immune response, potentially resulting in organ damage that can be fatal. Although therapeutic plasma exchange is not included in CRS management guidelines, this case shows that plasma exchange is feasible in at least some patients with severe CRS.

Abstract
One lead 3,6-disubstituted 1,2,4-triazolo[3,4-b][1,3,4]thiadiazole was identified as an inhibitor of shikimate dehydrogenase with antitubercular activity. Following up this compound, we optimized the lead through systematic modification of the 3 and 6 positions. The antitubercular activities in vitro, shikimate dehydrogenase inhibitory activities and cytotoxicity of derivatives were determined. We found IMB-SD62 with lower cytotoxicity and better activity. Thus, we studied the in vivo efficacy of IMB-SD62 against Mycobacterium tuberculosis and pharmacokinetics of IMB-SD62. In vivo acute M. tuberculosis H37Rv infection assay, IMB-SD62 showed antitubercular activity with the mean lung CFU counts decreasing 1.7 lg. The plasma pharmacokinetics study in rats showed that the oral bioavailability of IMB-SD62 was 14% and the half time was 1.05 h. The results of tissue distribution indicated that IMB-SD62 was mainly absorbed by liver and lung. In vitro metabolism study suggested that the metabolic ways of IMB-SD62 were dealkylated, oxidized and demethylated. CYP enzyme inhibition of IMB-SD62 in human liver microsomes was also evaluated. IMB-SD62 showed barely inhibition on CYP3A4 and CYP2D6. The excretion study manifested that IMB-SD62 was mainly eliminated by fecal excretion in rats. We concluded that based on these pharmaceutical properties, IMB-SD62 has the potential to be developed into new TB drug.

Abstract
BACKGROUND Two strains of Vibrio parahaemolyticus (ATCC 17802 and 33847) in shrimp, oyster, freshwater fish, pork, chicken and egg fried rice were evaluated for production of hemolysin and exoenzymes of potential importance to the pathogenicity of this bacterium. RESULTS The two strains of V. parahaemolyticus produced hemolysin, gelatinase, caseinase, phospholipase, urease, DNase and amylase in selected food matrices. Significantly higher (p < 0.05) hemolytic activity was produced by V. parahaemolyticus in egg fried rice > shrimp > freshwater fish > chicken > oyster > pork. But the exoenzyme activities were not consistent with the hemolytic activity profile, being significantly higher (p < 0.05) in shrimp > freshwater fish > chicken > oyster > pork > egg fried rice. Filtrates of V. parahaemolyticus from shrimp, freshwater fish and chicken given intraperitoneally to adult mice induced marked liver and kidney damage and were highly lethal compared with the filtrates of V. parahaemolyticus from oyster > egg fried rice > pork. CONCLUSION From in vitro and in vivo tests, it appears that the food matrix type has a significant impact on the activity of extracellular products and the pathogenicity of V. parahaemolyticus. From a food safety aspect, it is important to determine which food matrices can stimulate V. parahaemolyticus to produce additional extracellular factors. This is the first report of non-seafood including freshwater fish and chicken contaminated with V. parahaemolyticus to have been shown to be toxic to mice in vivo.

Abstract
Highly catalytic electrodes play a vital role in exploiting the capability of vanadium redox flow batteries (VRFBs), but they suffer from a tedious synthesis process and ambiguous interaction mechanisms for catalytic sites. Herein, a facile urea pyrolysis process was applied to prepare graphitic carbon nitride-modified graphite felt (GF@CN), and by the virtue of a density functional theory-assisted calculation, the electron-rich pyridinic nitrogen atom of CN granules is demonstrated as the adsorption center for redox species and plays the key role in improving the performance of VRFBs, with 800 cycles and an energy efficiency of 75% at 150 mA cm-2. Such experimental and computational collaborative investigations guide a realizable and cost-effective solution for other high-power flow batteries.

Abstract
BACKGROUND Empirical antifungal therapy is effective in some patients with risk factors for invasive fungal disease (IFD) who do not qualify for the EORTC/MSG criteria for IFD, but who fail to respond to anti-bacterial and anti-viral therapy. OBJECTIVE This retrospective single-center study investigated the epidemiology of IFD and empirical antifungal therapy in patients with hematological malignancies. METHODS This study recruited 893 patients with hematologic malignancies who had failed to respond to anti-bacterial and anti-viral treatment and received antifungal therapy, but not for antifungal prophylaxis. Antifungal therapy regimens included amphotericin B, voriconazole, itraconazole and caspofungin. A total of 689 patients were diagnosed with proven, probable, or possible IFD, while 159 patients did not meet the EORTC/MSG criteria for IFD diagnosis but recovered with antifungal treatment, and 45 were excluded from having IFD. Effective treatment was defined as the disappearance or resolution of clinical symptoms of IFD. RESULTS Patients diagnosed with IFD underwent chemotherapy at a higher proportion, and had significantly higher neutrophil counts compared to those who did not qualify for the EORTC/MSG criteria for IFD but responded to antifungals. The mortality due to all causes within 3 months was significantly higher for patients diagnosed with proven IFD, compared with those who did not qualify for the EORTC/MSG criteria for IFD. There was no discontinuation reported due to adverse events of caspofungin. CONCLUSION Empirical antifungal treatment could help save the lives of some patients with severe infections who are strongly suspected of having IFD.

Abstract
Water and protein are major constituents of shrimp, any changes in protein and the state of water influence the quality of shrimp. Therefore, a study to examine the law of moisture migration and protein denaturation under different freezing and thawing conditions is important. The proton density images of thawed frozen-shrimp revealed that the water loss during quick-freezing was much greater than that during slow freezing or microfreezing. At room temperature (25 °C), the water loss from brine-thawing was more than still-water thawing and still-water thawing was more than thawing spontaneously. Freezing-thawing resulted in uniform water redistribution in shrimp muscle. Nuclear magnetic resonance technology (low field magnetic imaging) was used to directly monitor the dynamic processes of fluidity state in shrimp and indirectly monitor protein denaturation and thereby determine the optimal method of freezing-thawing shrimp. Our research showed that microfreezing preservation minimized weight loss, juice leakage and protein denaturation in shrimp muscle during thawing. PRACTICAL APPLICATION Water is one of the major components in most organs and is an important factor that influences the shrimp muscle quality. Water migration patterns and subsequent effects on the shrimp muscle under different freezing and thawing conditions were examined using low field nuclear magnetic resonance (NMR) technology. This research provides a theoretical foundation for shrimp processing plants to improve the freezing and thawing process to obtain optimal quality and flavor of shrimp products.

Abstract
Objective: To investigate the prevalence of hypercholesterolemia among Chinese adults in different geographic areas, and to analyze the related factors. Methods: China Chronic and Non-Communicable Disease and Risk Factor Surveillance was conducted in 2013, based on 298 counties/districts in 31 provinces of Chinese mainland. The adults aged 18 years old were randomly selected using multi-stage stratified clustering sampling method. Information on chronic disease and risk factors was collected using face-to-face questionnaire interview and physical measurement. Blood samples were collected by local staffs. Serum total cholesterol (TC) was determined using standard method in a central laboratory. After excluding 565 participants missing key variables and 1 558 participants with abnormal TC values, a total of 174 976 participants were included. Weighted prevalence of hypercholesterolemia was calculated. Hypercholesterolemia related individual or geographic determinants were defined using multilevel logistic regression. Results: The prevalence of hypercholesterolemia in Chinese adults age 18 years old and above was 6.9% (95%CI: 6.4%-7.3%), ranged from 3.0% (95%CI: 2.5%-3.4%) in the northwest of China to 14.2% (95%CI: 12.9%-15.5%) in the south (χ(2)=183.42, P<0.001). The prevalence of hypercholesterolemia was higher in 6 provinces including Tianjin, Liaoning, Fujian, Guangdong, Guangxi, and Hainan (≥9.0%), but lower in 7 provinces including Shanxi, Shannxi, Gansu, Qinghai, Ningxia, Xinjiang, and Tibet (<3.9%). There was a 1.27 fold variation in hypercholesterolemia prevalence by provincial level, and 72.5% of the geographical variation in hypercholesterolemia prevalence was account for by area-level determinants. With multilevel logistic analysis, the individual risk factors associated with hypercholesterolemia included aging, higher education level or annual household income per capita, regular drinking, too much red meal intake, inactivity, overweight or obesity. For geographic factors, residents living at south China, counties/districts with higher urbanization rates, higher education level or lower standardized death rates were more likely to have hypercholesterolemia (all P<0.05). Conclusion: The prevalence of hypercholesterolemia was high in Chinese adults, it was different between regions and related with characteristics of population, individual behaviors and geographical regions.

Abstract
Objective: To explore the relations between the prevalence of multiple chronic diseases and cigarette smoking behavior in the Chinese adults. Methods: Based on the results: from the 2013 Chronic Disease Risk Factor Surveillance (NCD Surveillance), 176 534 Chinese residents aged 18 years and above, covering 298 counties (districts) in 31 provinces, was randomly recruited, using the multi-stage stratified clustering sampling method. Information on demographics, cigarette smoking (status, quantity and period) was obtained through face-to-face interviews and questionnaires. Anthropometric data and blood samples were collected and properly stored for analysis. Results In total, 175 386 adults were included for statistical analyses, with 42.7% as males and 57.3% as females. The prevalence rates of hypertension, high total cholesterol and high triglycerides were 30.4%, 7.2% and 18.0% in male smokers, 35.6%, 14.0%, 10.3% and 15.9% in female smokers respectively, which were all higher than those in the respective non-smokers. Male smokers were found under lower risk on hypertension, but 19% higher on total glycerides when compared with non-smokers of the same sex(OR=1.19, 95%CI:1.10-1.30), when multiple risk factors were under control. Male current smokers with more than 20 cigarettes per day have 41% (OR=1.41, 95%CI: 1.28-1.55) higher risk of high TG than non-smokers. Female smokers presented 40% (OR=1.40, 95%CI: 1.15-1.70) higher risk in high glycerides than the non-smokers. Specifically, women smoking longer than 20 years have 60% (OR=1.60, 95%CI: 1.31-1.95) higher risk of high TG than women smoking less than 20 years. Conclusions: Prevalence rates of certain chronic diseases were seen higher in smokers of both genders. People with longer history of smoking or being heavier smokers, appeared at advanced risk on developing chronic diseases.

Abstract
Although TRPV1 channels represent a key player of noxious heat sensation, the precise mechanisms for thermal hyperalgesia remain unknown. We report here that conditional knockout of deSUMOylation enzyme, SENP1, in mouse dorsal root ganglion (DRG) neurons exacerbated thermal hyperalgesia in both carrageenan- and Complete Freund’s adjuvant-induced inflammation models. TRPV1 is SUMOylated at a C-terminal Lys residue (K822), which specifically enhances the channel sensitivity to stimulation by heat, but not capsaicin, protons or voltage. TRPV1 SUMOylation is decreased by SENP1 but upregulated upon peripheral inflammation. More importantly, the reduced ability of TRPV1 knockout mice to develop inflammatory thermal hyperalgesia was rescued by viral infection of lumbar 3/4 DRG neurons of wild-type TRPV1, but not its SUMOylation-deficient mutant, K822R. These data suggest that TRPV1 SUMOylation is essential for the development of inflammatory thermal hyperalgesia, through a mechanism that involves sensitization of the channel response specifically to thermal stimulation. SUMOylation is a post translational modification. Here the authors show that TRPV1, which conveys thermal nociception, is SUMOylated in DRGs in inflammatory conditions and contributes to pain behavior in mice.

Abstract
This study aimed to investigate the effect of lactic acid bacteria (LAB) and smectite on the growth performance, nutrient digestibility and blood parameters of broilers that were fed diets contaminated with aflatoxin B1 (AFB1 ). A total of 480 newly hatched male Arbor Acres broilers were randomly allocated into four groups with six replicates of 20 chicks each. The broilers were fed diets with the AFB1 (40 μg/kg) challenge or without (control) it and supplemented with smectite (3.0 g/kg) or LAB (4.0 × 1010 CFU/kg) based on the AFB1 diet. The trial lasted for 42 days. The results showed that during days 1-42 of AFB1 challenge, the feed intake (FI) and body weight gain (BWG) were depressed (p < .05). The inclusion of LAB and smectite increased (p < .05) the BWG by 71.58 and 41.89 g/bird, respectively, which reached the level of the control diet (p ≥ .05), but there were no differences (p ≥ .05) in performance between LAB and smectite. LAB and smectite also increased (p < .05) the apparent total tract digestibility of the crude protein. Regarding the blood parameters, AFB1 decreased (p < .05) the levels of red blood cell count, haematocrit, mean corpuscular volume, haemoglobin, albumin and total protein. In the meantime, the AFB1 increased (p < .05) leucocyte counts, urea nitrogen, cholesterol, total bilirubin, creatinine, glutamic-pyruvic transaminase, glutamic oxaloacetic transaminase and alkaline phosphatase. By contrast, LAB and smectite affected (p < .05) these parameters in the opposite direction. It can be concluded that after the AFB1 challenge, LAB and smectite have similar effects on the growth and health of the broilers, suggesting that LAB could be an alternative against AFB1 in commercial animal feeds.

Abstract
Ancherythroculter wangi, is a unique freshwater fish and mainly distributed in the upper stream of Yangtze River and its tributary. In this study, the complete mitochondrial genome of A. wangi was first determined. The total length of the complete mitochondrial genome is 16,622 bp, contained 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, one D-loop locus, and an origin of replication on the light-strand (OL). The overall nucleotide composition was 31.19% A, 24.84% T, 27.79% C, 16.18% G, with 56.03% AT, respectively. Phylogenetic analysis both highly supported that A. wangi showed a close relationship with Culter mongolicus and A. kurematsui. These data would contribute to elucidate the evolutionary mechanisms and biogeography of Ancherythroculter and is useful for the conservation of genetics and stock evaluation for A. wangi.

Abstract
Climate changes, including chronic changes in precipitation amounts, will influence plant physiology and growth. However, such precipitation effects on switchgrass, a major bioenergy crop, have not been well investigated. We conducted a two-year precipitation simulation experiment using large pots (95 L) in an environmentally controlled greenhouse in Nashville, TN. Five precipitation treatments (ambient precipitation, and -50%, -33%, +33%, and +50% of ambient) were applied in a randomized complete block design with lowland "Alamo" switchgrass plants one year after they were established from tillers. The growing season progression of leaf physiology, tiller number, height, and aboveground biomass were determined each growing season. Precipitation treatments significantly affected leaf physiology, growth, and aboveground biomass. The photosynthetic rates in the wet (+50% and +33%) treatments were significantly enhanced by 15.9% and 8.1%, respectively, than the ambient treatment. Both leaf biomass and plant height were largely increased, resulting in dramatically increases in aboveground biomass by 56.5% and 49.6% in the +50% and +33% treatments, respectively. Compared to the ambient treatment, the drought (-33% and -50%) treatments did not influence leaf physiology, but the -50% treatment significantly reduced leaf biomass by 37.8%, plant height by 16.3%, and aboveground biomass by 38.9%. This study demonstrated that while switchgrass in general is a drought tolerant grass, severe drought significantly reduces Alamo's growth and biomass, and that high precipitation stimulates its photosynthesis and growth.

Abstract
Objective: To investigate the geographical variation of prediabetes in adults in different regions of China, and to analyze the related factors of prediabetes. Methods: Data was obtained from China Chronic Disease and Related Risk Factor Surveillance in 2013. The surveillance adopted multiple-stage stratified cluster random sampling method, which sampled 177 099 residents aged above 18 years old among 298 surveillance points in 31 provinces of Chinese Mainland. Questionnaire interview was used to obtain demographic variables, personal living style, and socio-economical information. Physical examination was conducted and fasting venous blood sample and (oral glucose tolerance test-2 hours, OGTT-2 h) venous blood sample were obtained from the participants. A total of 171 567 residents aged 18 and above were included in the analysis. The prevalence of prediabetes was analyzed by provinces and by China's geographical regions, after complex weighting. Multilevel logistic models were established to explore the related factors of prediabetes on the area level and individual level. Results: The prevalence of prediabetes among residents aged 18 and above was 16.6% (95%CI: 15.6%-17.6%) in China. The prevalence of prediabetes was the highest (18.3%) in the south China and lowest (13.1%) in the northwest area. The difference of the prevalence in different areas were not statistically significant (P=0.510). If categorized the prevalence of prediabetes into 5 groups by quintile, Hainan, Jilin, Shandong, Anhui, Hunan and Chongqing were in the highest group of prevalence of prediabetes (18.6%-22.7%), and Tibet, Qinghai, Gansu, Ningxia, Guizhou, and Jiangxi were in the lowest group (7.6%-12.6%). The variance of prevalence of prediabetes on the county level (MOR: 1.60 (95%CI:1.53-1.67)) was more diverse than the province level (MOR: 1.21(95%CI:1.08-1.29)) and higher than the street level (1.23 (95%CI:1.14-1.30)). Several factors increased risk of pre-diabetes, including smoking, hazardous drinking and harmful drinking, drinking in the past 30 days, overweight, obesity, central obesity, sugary drink intake, hypertension, high total cholesterol, high triglycerides, high blood low-density lipoprotein cholesterol, low blood high-density lipoprotein cholesterol (all P<0.05). After adjusted the above variables, 92.5% of variance of prediabetes prevalence conld be explained on the provincial level. Conclusion: The geographical distribution of prediabetes in adults in China differed by geographic areas, and it significantly varied on the county level. The related variables included demographic variables, personal behavior, and geographic related variables.

Abstract
The generation of conditional mutants has been an effective approach to studying bacteria and validating drug targets, and mutants of Mycobacteria are no exception. However unlike other bacteria, there is still a paucity of available tools for Mycobacteria. We constructed a new plasmid containing tetracycline-repressive expression system (TetRr1.7) and Xer Site-Specific recombinase system to generate label-free controllable expression strains. The plasmid was subsequently used to construct a strain of M. tuberculosis expressing the only copy of d-alanine:d-alanine ligase under the control of the tetracycline-repressive promoter. The results showed that the mutant strain lost the ability of colony formation, became more sensitive to d-cycloserine and the cell wall of the mutant strain was disrupted when anhydrotetracycline was added to the medium. Taken together these observations, confirmed that the expression of d-alanine:d-alanine ligase was tightly controlled by the promoter. In conclusion, the new plasmid is a convenient tool for constructing stable conditional mutant strains in Mycobacteria and can be used for future target identification.

Abstract
The growth and hemolytic activity profiles of two Vibrio parahaemolyticus strains (ATCC 17802 and ATCC 33847) in shrimp, oyster, freshwater fish, pork, chicken, and egg fried rice were investigated, and a prediction system for accurate microbial risk assessment was developed. The two V. parahaemolyticus strains displayed a similar growth and hemolysin production pattern in the foods at 37°C. Growth kinetic parameters showed that V. parahaemolyticus displayed higher maximum specific growth rate and shorter lag time values in shrimp > freshwater fish > egg fried rice> oyster > chicken > pork. Notably, there was a similar number of V. parahaemolyticus in all of these samples at the stationary phase. The hemolytic activity of V. parahaemolyticus in foods increased linearly with time ( R2 > 0.97). The rate constant ( K) of hemolytic activity was higher in shrimp, oyster, freshwater fish, and egg fried rice than in pork and chicken. Significantly higher hemolytic activity of V. parahaemolyticus was evident in egg fried rice > shrimp > freshwater fish > chicken > oyster > pork. The above-mentioned results indicate that V. parahaemolyticus could grow well regardless of the food type and that contrary to current belief, it displayed a higher hemolytic activity in some nonseafood products (freshwater fish, egg fried rice, and chicken) than in one seafood (oyster). The prediction system consisting of the growth model and hemolysin production algorithm reported here will fill a gap in predictive microbiology and improve significantly the accuracy of microbial risk assessment of V. parahaemolyticus.

Abstract
The effects of intensive nitrogen (N) fertilizations on spatial distributions of soil microbes in bioenergy croplands remain unknown. To quantify N fertilization effect on spatial heterogeneity of soil microbial biomass carbon (MBC) and N (MBN), we sampled top mineral horizon soils (0-15 cm) using a spatially explicit design within two 15-m2 plots under three fertilization treatments in two bioenergy croplands in a three-year long fertilization experiment in Middle Tennessee, USA. The three fertilization treatments were no N input (NN), low N input (LN: 84 kg N ha−1 in urea) and high N input (HN: 168 kg N ha−1 in urea). The two crops were switchgrass (SG: Panicum virgatum L.) and gamagrass (GG: Tripsacum dactyloides L.). Results showed that N fertilizations little altered central tendencies of microbial variables but relative to LN, HN significantly increased MBC and MBC:MBN (GG only). HN possessed the greatest within-plot variances except for MBN (GG only). Spatial patterns were generally evident under HN and LN plots and much less so under NN plots. Substantially contrasting spatial variations were also identified between croplands (GG > SG) and among variables (MBN, MBC:MBN > MBC). This study demonstrated that spatial heterogeneity is elevated in microbial biomass of fertilized soils likely by uneven fertilizer application in bioenergy crops.

Abstract
OBJECTIVE To investigate the effetcs of autophagy on the proliferation of renal carcinoma (RCCs). MATERIALS AND METHODS Authophagy related protein 7 (Atg7)-overexpressing and knockdown RCC cell lines were established using lentiviral transfection and shRNA interference, respectively. (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) (MTT) was used to determine the Cell growth rate, and western blot was used to determine the expression of protein. In order to establish xenograft animal models, stable transfected cells were injected into nude mice. After that those mice were used to detect the effect of autophagy on the growth of RCC in vivo. RESULTS Atg7 overexpression could up-regulate the level of LC3II in RCC cell lines, while Atg7-knockdown suppressed the expression of light chain 3 II (LC3II) in RCC cell lines. Atg7-overexpression cells exhibited a decreased growth profile, while suppressing the expression of Atg7 could accelerate the growth of RCC formed tumors. CONCLUSIONS Our data indicated that autophagy could suppress the growth of RCC cells in vivo and in vitro, and autophagy appeared to be a new therapeutic target for treating advanced renal cell carcinoma.

Abstract
We describe the clinical, morphologic, immunophenotypic and molecular genetic features of 15 cases of acute myeloid leukemia (AML) with t(4;12)(q12;p13). There were 9 men and 6 women, with a median age of 50 years (range, 17–76). Most patients had hypercellular bone marrow with a median blast count of 58% and multilineage dysplasia. Flow cytometry analysis showed myeloid lineage with blasts positive for CD13, CD33, CD34, CD38, CD117 and HLA-DR. Interestingly, aberrant CD7 expression was detected in 12/14 cases, and myeloperoxidase was either negative (3/15) or positive in only a small subset of the blasts (12/15). t(4;12)(q12;p13) was detected at time of initial diagnosis in 4 and at relapse or progression in 9 patients. The initial karyotype was unknown in 2 cases. FISH analysis showed PDGFRA-ETV6 rearrangement in all 7 cases assessed. FLT3 ITD was detected in 2/11 cases and IDH2 and JAK2 mutation were each detected in 1/2 cases assessed. There were no mutations of KRAS (0/8), NRAS (0/8), CEBPA (0/3), KIT (0/3), NPM1 (0/3) or IDH1 (0/2). All patients received aggressive multiagent chemotherapy; 7 patients additionally received stem cell transplantation. With a median follow-up of 10 months (range, 6–51), 13 patients died of AML, 1 patient had persistent disease, and 1 patient was lost to follow-up. In summary, AML with t(4;12)(q12;p13) is usually associated with myelodysplasia, aberrant CD7 expression, weak of absent myeloperoxidase expression, frequent PDGFRA-ETV6 fusion, and an aggressive clinical course. The molecular findings suggest that there may be a role for tyrosine kinase inhibitors in patient management.

Abstract
Although food and drink have traditionally been prohibited in libraries, in recent years, there have been increased joint ventures between libraries and coffee shops like Starbucks. Although library cafés are perceived mostly for social networking and recreational purposes, an increasing number of students are conducting both their formal and informal learning at the library cafés, instead of inside the physical libraries. Using a quantitative comparative approach, this study also aims to identify the similarities and differences in the usage of library cafés amongst students at three different universities in Asia and the United States – namely, the University of Tsukuba, located in Japan, the University of Hong Kong, and the University of Kentucky in the USA. Furthermore, this study explores the educational, social, and recreational roles that library cafés play in the students’ college experience and daily lives. Online questionnaire surveys were used to gauge library patrons’ usage and perceptions of both the library and café spaces, as well as their preferences for formal and informal learning and recreation. From the 314 responses collected from all three universities, the results indicated that a majority of the respondents considered the library café as an important part of their campus life, though a majority of them would still prefer formal learning within the library building, and certain recreational activities outside the library café. Besides, the library café also functions like a multi-functional hub where everyone can find their own use, ranging from being a place for learning to a place for socialization purposes.

Abstract
Shewanella putrefaciens biofilm formation is of great concern for the shrimp industry because it adheres easily to food and food-contact surfaces and is a source of persistent and unseen contamination that causes shrimp spoilage and economic losses to the shrimp industry. Different concentrations of an antimicrobial lipopeptide, the fermentation product of Bacillus subtilis, AMPNT-6, were tested for the ability to reduce adhesion and disrupt S. putrefaciens preformed biofilms on two different contact surfaces (shrimp shell, stainless steel sheet). AMPNT-6 displayed a marked dose- and time-dependent anti-adhesive effect>biofilm removal. 3MIC AMPNT-6 was able both to remove biofilm and prevent bacteria from forming biofilm in a 96-well polystyrene microplate used as the model surface. 2MIC AMPNT-6 prevented bacteria from adhering to the microplate surface to form biofilm for 3h and removed already existing biofilm within 24h. Secretion of extracellular polymeric substances incubated in LB broth for 24h by S. putrefaciens was minimal at 3× MIC AMPNT-6. Scanning electron microscopy showed that damage to S. putrefaciens bacteria by AMPNT-6 possibly contributed to the non-adherence to the surfaces. Disruption of the mature biofilm structure by AMPNT-6 contributed to biofilm removal. It is concluded that AMPNT-6 can be used effectively to prevent attachment and also detach S. putrefaciens biofilms from shrimp shells, stainless steel sheets and polystyrene surfaces.

Abstract
Accurate analyses of total T-2 (free and modified) in aquatic organisms including shrimp are important as the hazard caused by T-2 has been caught increasing attention. Therefore, acurate analysis of free T-2 especially of modified T-2 in shrimp tissues is important. A rapid, sensitive, and validated method for quantitative determination of free T-2 and modified T-2 toxin was developed using immunomagnetic-bead based enzyme-linked immunosorbent assay (IMB-ELISA). Super paramagnetic particles with a carboxyl group activated by an ester method coupled with envelope antigen 3- acetylneosolaniol- hemisuccinate - ovalbumin (3-Ac-NEOS-HS-OVA) was used to form immunomagnetic beads which could bind to T-2 skeletal structure antibodies. The conditions for magnetic bead coating of T-2 skeletal structure antibodies, and the concentrations of the polyclonal antibody and HRP-labeled goat anti-rabbit antibody were optimized. A good linear relationship with T-2 concentrations ranging from 5-75ng/mL (R2 =0.9965) was observed. The detection limit of different shrimp tissues of the IMB-ELISA ranged from 2.53 to 3.20ng/mL. And the IC50 was 63ng/mL. The recovery varied from 86% to 99% with a standard deviation of 2.8-5.8%. The application of this method to study the distribution in tissues showed that the total T-2 concentration in hepatopancreas was 26.7µg/kg > blood > head > muscle in the highest dose group of 12.2mg/kg. Our research showed a combination of ELISA and immunomagnetic bead technology provide a new, convenient approach to significantly improve the accuracy and sensitivity of total T-2 measurement in shrimp tissues.

Abstract
Rain-induced soil CO2 pulse, a rapid excitation in soil CO2 flux after rain, is ubiquitously observed in terrestrial ecosystems, yet the underlying mechanisms in tropical forests are still not clear. We conducted a rain simulation experiment to quantify rain-induced changes in soil CO2 flux and microbial community composition in a tropical forest. Soil CO2 flux rapidly increased by ~83% after rains, accompanied by increases in both bacterial (~51%) and fungal (~58%) Phospholipid Fatty Acids (PLFA) biomass. However, soil CO2 flux and microbial community in the plots without litters showed limited response to rains. Direct releases of CO2 from litter layer only accounted for ~19% increases in soil CO2 flux, suggesting that the leaching of dissolved organic carbon (DOC) from litter layer to the topsoil is the major cause of rain-induced soil CO2 pulse. In addition, rain-induced changes in soil CO2 flux and microbial PLFA biomass decreased with increasing rain sizes, but they were positively correlated with litter-leached DOC concentration rather than total DOC flux. Our findings reveal an important role of litter-leached DOC input in regulating rain-induced soil CO2 pulses and microbial community composition, and may have significant implications for CO2 losses from tropical forest soils under future rainfall changes.

Abstract
Pulmonary fibrosis is a complex pathological process characterized by massive destruction of the structure of lung tissues and aggravated pulmonary function impairment. The underlying mechanisms of pulmonary fibrosis are incompletely understood and therefore limited treatment options are available currently. Here, we report that MLN4924, an NEDD8 activation enzyme (NAE) activity-inhibiting molecule, blocks the maintenance and progression of established pulmonary fibrosis. We found that MLN4924 acts against bleomycin-induced pulmonary fibrosis mainly at the early inflammatory stage. Pharmacologically targeting the neddylation of Cullin-Ring E3 ligase (CRL) by MLN4924, significantly abrogated NF-κB responses, suppressed MAPK activity, and reduced secretion of TNF-α-elicited pro-inflammatory cytokines and MCP1-induced chemokines. MLN4924 inhibited pro-inflammatory responses while maintaining or increasing the production of the anti-inflammatory mediators such as anti-inflammatory interleukins (ILs) following bleomycin administration, which is closely correlated to its blocking NF-κB-mediated signaling. Consistently, our studies identified MLN4924 as a promising therapeutic drug for pulmonary fibrosis and suggested a potential role of MLN4924 that fine tunes the MAPK signaling pathway controlling the inflammatory reactions at the early stages of pulmonary fibrosis. In addition, our findings may broaden the potential practical application of MLN4924 as an effective therapeutic strategy against other inflammation-associated diseases.
