Abstract
The objective of this study was to investigate the immunopotential of ruminal lipopolysaccharides (LPS) on cultured primary bovine rumen epithelial cells (REC). Primary bovine REC were isolated from 6 yearling steers and grown in culture for 3 experiments. Experiment 1 aimed to determine the immunopotential of ruminal LPS, experiment 2 aimed to assess tolerance to chronic LPS exposure, and experiment 3 aimed to evaluate antagonistic interactions between ruminal and Escherichia coli LPS. In experiments 1 and 2, REC were exposed to nonpyrogenic water, 20 μg/mL E. coli LPS (EC20), 10 μg/mL ruminal LPS, 20 μg/mL ruminal LPS, and 40 μg/mL ruminal LPS, either continuously or intermittently. For the continuous exposure, REC underwent a 6 h exposure, whereas for the intermittent exposure, the procedure was: (1) a 12 h continuous exposure to treatments followed by LPS removal for 24 h and then another 12 h of exposure (RPT), and (2) a 12 h continuous exposure to treatments followed by LPS removal and a recovery period of 36 h (RCV). In experiment 3, REC were exposed to nonpyrogenic water, 1 μg/mL E. coli LPS, 1 μg/mL ruminal LPS to 1 μg/mL E. coli LPS, 10 μg/mL ruminal LPS to 1 μg/mL E. coli LPS, and 50 μg/mL ruminal LPS to 1 μg/mL E. coli LPS. Each experiment was done as a complete randomized block design with 6 REC donors. The REC-donor was used as blocking factor. Each treatment had 2 technical replicates, and treatment responses for all data were analyzed with the MIXED procedure of SAS. For all experiments, total RNA was extracted from REC and real-time quantitative PCR was performed to determine the relative expression of genes for toll-like receptors (TLR2 and TLR4), proinflammatory cytokines (TNF, IL1B, and IL6), chemokines (CXCL2 and CXCL8), growth factor-like cytokines (CSF2 and TGFB1), and a lipid mediator (PTGS2). In experiment 1, the targeted genes were upregulated by EC20, whereas all ruminal LPS treatments resulted in a lower transcript abundance. Regarding RPT, and RCV condition, in experiment 2, the expression of targeted genes was not affected or was at a lower abundance to EC20 when compared with ruminal LPS treatments. Lastly, in experiment 3, all targeted genes resulted in lower or similar transcript abundance on all ruminal LPS ratios. Overall, our results indicate that ruminal LPS have a limited capacity to activate the TLR4/NF-kB pathway and to induce the expression of inflammatory genes.

Abstract
Aphis craccivora (Hemiptera: Aphididae) is an important pest affecting various crops worldwide. However, only few studies have been conducted on the infection of A. craccivora by Lecanicillium and related insecticidal mechanisms. We investigated the infection process of A. craccivora by Lecanicillium araneicola HK-1 using fluorescence microscopy and scanning electron microscopy (SEM), and our results indicated that the conidia of strain HK-1 easily attached to the feet and dorsum of A. craccivora. The activities of chitinase and extracellular protease were induced in the aphid after treatment with HK-1. A bioassay on A. craccivora showed that the median lethal concentration (LC50) of the fungus crude extract was 24.00 mg mL-1 for 24 h of treatment. Additionally, the results showed that the crude extract disrupted the enzyme system of A. craccivora, inducing the inhibition of carboxylesterase (CarE) and the induction of glutathione S-transferase (GST) and acetylcholinesterase (AChE). Combining these results with those of a gas chromatography-mass spectrometry (GC-MS) analysis, it is suggested that p-cymene, hymecromone, 9,12-octadecadienoic acid (Z, Z) methyl ester, and 9,12-octadecadienoic acid (Z, Z) may be connected to the insecticidal effects we observed. This study provides a theoretical basis for the use of L. araneicola HK-1 as a potential biological control agent.

Abstract
PURPOSE/OBJECTIVE(S) Limited stage small-cell lung cancer (LS-SCLC) is associated with poor prognosis. We aimed to assess the efficacy and safety of high-dose, hyperfractionated thoracic radiotherapy of 54 Gy in 30 fractions compared with standard dose (45 Gy in 30 fractions) as a first-line treatment for LS-SCLC. MATERIALS/METHODS The study was an open-label, randomized, phase 3 trial, done at 16 public hospitals in China. Key inclusion criteria were patients aged 18-70 years, with previously histologically or cytologically confirmed LS-SCLC, previously untreated or received 1-2 courses of intravenous cisplatin (75 mg/m²of body-surface area, on day 1 or divided into two days of each cycle) or carboplatin (area under the curve of 5 mg/mL per min, day 1 of each cycle)and intravenous etoposide (100 mg/m²of body-surface area, on days 1-3 of each cycle), and an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.Eligible patients were randomly assigned (1:1) to receive volumetric-modulated arc radiotherapy (VMAT) of 45 Gy in 30 fractions or the simultaneous integrated boost VMAT (SIB-VMAT) of 54 Gy in 30 fractions to the primary lung tumor and lymph node metastases starting 0-42 days after the first chemotherapy course. Both groups of patients received thoracic radiotherapy twice per day and 10 fractions per week. Prophylactic cranial radiation (PCI, 25 Gy in 10 fractions) was implemented to patients with responsive disease. The primary endpoint was overall survival. Safety was analyzed in the as-treated population. RESULTS Between June 30, 2017, and April 6, 2021, 224 eligible patients were enrolled and randomly assigned to 54 Gy (n = 108) or 45 Gy (n = 116). Median follow-up for the primary analysis was 45 months (IQR 41-48). Median overall survival was significantly improved in the 54 Gy group (62.4 months) compared with the 45 Gy group (43.1 months; p = 0.001). Median progression-free survival was significantly improved in the 54 Gy group (30.5 months) compared with the 45 Gy group (16.7 months; p = 0.044). The most common grade 3-4 adverse events were neutropenia (30 [28%] of 108 patients in the 54 Gy group vs 27 [23%] of 116 patients in the 45 Gy group), neutropenic infections (6 [6%] vs 2 [2%]), thrombocytopenia (13 [12%] vs 12 [10%]), anemia (6 [6%] vs 4 [3%]), and esophagitis (1 [1%] vs 3 [3%]). Treatment-related serious adverse events occurred in 9 [8%] patients in the 54 Gy group and 16 [14%] patients in the 45 Gy group. There were one treatment-related deaths in 54 Gy group (myocardial infarction). CONCLUSION Compared with standard thoracic radiotherapy dose of 45 Gy, the high dose of 54 Gy improved overall survival and progression-free survival without increasing toxicities in patients with LS-SCLC, supporting twice-daily hyperfractionated thoracic radiotherapy of 54 Gy with concurrent chemotherapy is an alternative treatment option for LS-SCLC. This study is complete and registered with ClinicalTrials.gov, NCT03214003.

Abstract
PURPOSE/OBJECTIVE(S) Growing numbers of clinical trials are testing the efficacy of incorporating local therapy into programmed death receptor (ligand) 1 (PD-1/PD-L1) inhibitors in metastatic non-small cell lung cancer (NSCLC), but the optimal timing and patient selection are still controversial. We aimed to examine the patterns of maximum tumor response and treatment failure in PD-1/PD-L1 inhibitor-treated NSCLC, and explore the potential clinical value of local consolidative therapy (LCT) in those with oligo-residual disease (ORD). MATERIALS/METHODS Metastatic NSCLC treated with PD-1/PD-L1 inhibitors in three academic centers from May 2018 to December 2021 were retrospectively reviewed and those derived clinical benefit, defined as having objective response or durable stable disease lasting≥6months, were finally enrolled. Patterns of tumor response and treatment failure were extensively analyzed. ORD was defined as residual tumor distribution limited to 3 organs and 5 lesions, otherwise was defined as multiple residual disease (MRD). Local therapies targeting the residual tumor lesions performed after PD-1/PD-L1 inhibitors initiation and before initial disease progression, were considered as LCT. The primary endpoints were the overall survival (OS) and progression-free survival (PFS). RESULTS Of the 318 patients enrolled, ORD and MRD were documented in 122 (38.4%) and 196 (61.6%) patients, respectively. Those who developed ORD had a significantly longer OS than those with MRD (p = 0.006). The median time to best response was 4 months and more than 50% of the initial disease progression developed only from the residual tumor lesions, providing the preliminary rationale of LCT. Among the 122 patients with ORD, those receiving LCT (n = 39) had significantly longer PFS (p = 0.04) and OS (p<0.001) than those without LCT. Moreover, LCT remained one of the independent predictors of improved PFS and OS after Cox analyses. CONCLUSION Local consolidative therapy seems to be feasible and may provide extra survival benefit for metastatic NSCLC patients with oligo-residual disease after PD-1/PD-L1 inhibitor treatment.

Abstract
Integrating sponge iron (SI) and microelectrolysis individually into constructed wetlands (CWs) to enhance nitrogen and phosphorus removal are challenged by ammonia (NH4+-N) accumulation and limited total phosphorus (TP) removal efficiency, respectively. In this study, a microelectrolysis-assisted CW using SI as filler surrounding the cathode (e-SICW) was successfully established. Results indicated that e-SICW reduced NH4+-N accumulation and intensified nitrate (NO3--N), the total nitrogen (TN) and TP removal. The concentration of NH4+-N in the effluent from e-SICW was lower than that from SICW in the whole process with 39.2-53.2 % decrease, and as the influent NO3--N concentration of 15 mg/L and COD/N ratio of 3, the removal efficiencies of NO3--N, TN and TP in e-SICW achieved 95.7 ± 1.9 %, 79.8 ± 2.5 % and 98.0 ± 1.3 %, respectively. Microbial community analysis revealed that hydrogen autotrophic denitrifying bacteria of Hydrogenophaga was highly enriched in e-SICW.

Abstract
Ionic liquids (ILs) are widely used in frontier fields because of their highly tunable properties. Although ILs may have adverse effects on organisms, few studies have focused on their effect on earthworm gene expression. Herein we investigated the toxicity mechanism of different ILs towards Eisenia fetida using transcriptomics. Earthworms were exposed to soil containing different concentrations and types of ILs, and behavior, weight, enzymatic activity and transcriptome were analyzed. Earthworms exhibited avoidance behavior towards ILs and growth was inhibited. ILs also affected antioxidant and detoxifying enzymatic activity. These effects were concentration and alkyl chain length-dependent. Analysis of intrasample expression levels and differences in transcriptome expression levels showed good parallelism within groups and large differences between groups. Based on functional classification analysis, we speculate that toxicity mainly occurs through translation and modification of proteins and intracellular transport functions, which affect protein-related binding functions and catalytic activity. KEGG pathway analysis revealed that ILs may damage the digestive system of earthworms, among other possible pathological effects. Transcriptome analysis reveals mechanisms that cannot be observed by conventional toxicity endpoints. This is useful to evaluate the potential environmental adverse effects of the industrial use of ILs.

Abstract
Nowadays, polyhalogenated carbazoles (PHCZs) are a major pollutant that has recently sparked widespread concern. In this work, peroxymonosulfate (PMS) was activated by zero valent iron (Fe0) to remove 3,6-dichlorocarbazole (3,6-CCZ). First, the key parameters influencing 3,6-CCZ degradation (PMS dosage, Fe0 dosage, initial pH, temperature and co-existing ions) were determined. Under the determined optimum conditions, the removal rate of 3,6-CCZ reached 100% within 1.5 h. Sulfate radicals (SO4·-), hydroxyl radicals (OH·), and singlet oxygen (1O2) generated in the reaction were directly identified with 0.1 M 5,5-dimethyl-1-pyrrolidine N-oxide (DMPO) by in-situ electron paramagnetic resonance (EPR) and indirectly identified by radical quenching experiments. The main reactive oxygen species (ROS) were different from most reported hydroxyl radicals (OH·) and sulfate radicals (SO4·-). In this study, it was found that OH· and 1O2 play a major role. Then, fresh and reacted Fe0 were characterized by XRD, SEM, and XPS. Iron corrosion products such as Fe2O3, Fe3O4, and FeOOH were generated. Finally, 3,6-CCZ degradation intermediates were identified by GC-MS and its degradation pathway was speculated. The intermediate pathway confirmed the combined action of (OH·) and (1O2) in 3,6-CCZ removal. This study provides new insight into the activation mechanism of Fe0-activated PMS and the removal mechanism of 3,6-CCZ.Highlights Fe0 is a long-lasting and efficient catalyst of PMS for the degradation of 3,6-CCZ.The key parameters influencing 3,6-CCZ degradation were determined.The degradation pathways of 3,6-CCZ were inferred.OH· and 1O2 were the main ROS in Fe0-activated PMS system.

Abstract
Bacillus bacteria can produce abundant secondary metabolites that are useful for biocontrol, especially in maintaining plant root microecology, and for plant protection. In this study, we determine the indicators of six Bacillus strains for colonization, promotion of plant growth, antimicrobial activity, and other aspects, with the aim of obtaining a compound bacteriological agent to construct a beneficial Bacillus microbial community in plant roots. We found that there was no significant difference in the growth curves of the six Bacillus strains over 12 h. However, strain HN-2 was found to have the strongest swimming ability and the highest bacteriostatic effect of n-butanol extract on the blight-causing bacteria Xanthomonas oryzae pv. oryzicola. The hemolytic circle produced by the n-butanol extract of strain FZB42 was the largest (8.67 ± 0.13 mm) and had the greatest bacteriostatic effect on the fungal pathogen Colletotrichum gloeosporioides, with a bacteriostatic circle diameter of 21.74 ± 0.40 mm. Strains HN-2 and FZB42 can rapidly form biofilms. Time-of-flight mass spectrometry and hemolytic plate tests showed that strains HN-2 and FZB42 may have significantly different activities because of their ability to produce large quantities of lipopeptides (i.e., surfactin, iturin, and fengycin). Different growth-promoting experiments revealed that the strains FZB42, HN-2, HAB-2, and HAB-5 had better growth-promoting potential than the control, and therefore these four strains were compounded in an equal ratio and used to treat pepper seedlings through root irrigation. We found an increase in the stem thickness (13%), leaf dry weight (14%), leaf number (26%), and chlorophyll content (41%) of pepper seedlings treated with the composite-formulated bacterial solution compared to the optimal single-bacterial solution treatment. Furthermore, several of these indicators increased by an average of 30% in the composite solution-treated pepper seedlings compared with the control water treatment group. In conclusion, the composite solution obtained by compounding strains FZB42 (OD600 = 1.2), HN-2 (OD600 = 0.9), HAB-2 (OD600 = 0.9), and HAB-5 (OD600 = 1.2) in equal parts highlights the advantages of a single bacterial solution, which includes achieving good growth promotion and antagonistic effects against pathogenic bacteria. The promotion of this compound-formulated Bacillus can reduce the application of chemical pesticides and fertilizers; promote plant growth and development; avoid the imbalances of soil microbial communities and thus reduce the risk of plant disease; and provide an experimental basis for the production and application of various types of biological control preparations in the future.

Abstract
Ionic liquids (ILs1) are used widely because of their excellent properties. However, their ecotoxicity for environment has aroused great concern. Here we studied, the toxicity of three ILs with different numbers of methyl substituents and anions as well as the combined effect of heavy metals to edible algae Nostoc punctiforme. The results show that fresh weight and chlorophyll content decreased, indicating that the growth and photosynthesis were adversely affected. Polysaccharides and soluble protein contents decreased, resulting in a reduced nutritional value of Nostoc punctiforme. ILs can produce many reactive oxygen species (ROS), which lead to increased the malondialdehyde (MDA) content. In order to remove excessive ROS, antioxidant enzymes activity is increased, but decreases under high IL concentration, because the structure and function of the enzymes became damaged. ILs cause stress to algae, as the cell ultrastructure is indicating by increased amounts of starch and osmiophilic globules. The combined action of heavy metals with ILs decreases the antioxidant enzymes activity and chlorophyll content, and increases the MDA content. The results show that the order of toxicity is [C8MIM]Cl >[C8MIM]Br> [C8DMIM]Br. The combination of heavy metals and ILs cause an increase of the toxicity to Nostoc punctiforme.

Abstract
A serum-free, highly purified Vero cell rabies vaccine (PVRV-NG) is under development. We previously demonstrated that pre-exposure prophylaxis (PrEP) with PVRV-NG had a satisfactory safety profile and was immunogenically non-inferior to the licensed purified Vero cell rabies vaccine in adults. Here, we evaluated the safety and immunogenic non-inferiority of PrEP with PVRV-NG compared to the licensed human diploid cell vaccine (HDCV) in healthy adults (NCT01784874). Participants received three vaccinations (days 0, 7, and 28) as PrEP with or without a booster injection after 12 months. Rabies virus neutralising antibodies (RVNA) were evaluated on days 0, 28 (subgroup only), and 42, and Months 6, 12, and 12 + 14 days (booster group only). Non-inferiority (first primary objective) was based on the proportion of participants with RVNA titres ≥ 0.5 IU/mL (World Health Organization criteria for seroconversion) on day 42, expected to be ≥ 99% (second primary objective). Safety was evaluated after each dose and monitored throughout the study. At day 42, PVRV-NG was non-inferior to HDCV and the first primary objective was met; seroconversion was observed for 98.3% of PVRV-NG recipients and 99.1% of HDCV recipients. As < 99% of participants in the PVRV-NG group had RVNA titres ≥ 0.5 IU/mL, the second primary objective was not met. Booster vaccination produced a strong increase in RVNA titres for all groups, primed with PVRV-NG or HDCV. RVNA geometric mean titres tended to be higher for HDCV than PVRV-NG primary vaccine recipients. In a complementary evaluation using alternative criteria for seroconversion (complete virus neutralization at 1:5 serum dilution), 99.6% and 100% of participants in the PVRV-NG and HDCV groups, respectively, achieved seroconversion across the vaccine groups. No major safety concerns were observed during the study. PVRV-NG was well tolerated, with a similar safety profile to HDCV in terms of incidence, duration, and severity of adverse events after primary and booster vaccinations. ClinicalTrials.gov number: NCT01784874.

Abstract
OBJECTIVE To investigate the protective effect of Echinococcus granulosus hydatid cyst fluid protein (HCFP) on ovalbumin (OVA)-induced allergic rhinitis (AR) in mice. METHODS Twenty-four BALB/c mice at ages of 8 to 10 weeks, each weighing approximately 20 g, were randomly divided into four groups, including groups A (blank control group), B (blank intervention group), C (AR model group) and D (AR+HCFP intervention group), with 6 mice in each group. On days 0, 2, 4, 6, 8, 10 and 12, mice in groups A, B, C and D were injected with 200 μL sterile phosphate buffered saline (PBS), 200 μL sterile PBS containing 20 μg HCFP, 200 μL sterile PBS containing 50 μg OVA and 5 mg Al(OH)3 gel, and 200 μL sterile PBS containing 50 μg OVA, 5 mg Al(OH)3 gel and 20 μg HCFP, respectively. On days 14 to 20, mice in groups A, B, C and D were administered with 40 μL sterile PBS, 40 μL sterile PBS containing 20 μg HCFP, 40 μL sterile PBS containing 2 mg OVA and 40 μL sterile PBS containing 2 mg OVA and 20 μL HCFP by nasal drop, respectively. Mouse behavioral changes were observed and behavioral scores were estimated. The serum levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), IL-5, IL-10, transforming growth factor-β (TGF-β) and OVA-specific IgE antibody (OVA-sIgE) were measured using enzyme-linked immunosorbent assay (ELISA), and the pathological changes of mouse nasal mucosa were observed by hematoxylin and eosin (HE) staining. RESULTS The mean behavioral score was significantly greater in Group C (6.83 ± 0.50) than in groups A (1.17 ± 0.52) and B (1.33 ± 0.52) (P < 0.05), while a lower mean behavioral score was estimated in Group D (3.50 ± 0.50) than in Group C (P < 0.05). There were significant differences among the groups in terms of serum IFN-γ (F = 4.08, P < 0.05), IL-4 (F = 275.90, P < 0.05), IL-5 (F = 96.82, P < 0.05), IL-10 (F = 77.67, P < 0.05), TGF-β (F = 9.98, P < 0.05) and OVA-sIgE levels (F = 44.69, P < 0.05). The serum IFN-γ level was significantly lower in Group C than in groups A, B and C (P < 0.05), and the serum levels of IL-4, IL-5 and OVA-sIgE were significantly higher in Group C than in groups A, B and C (P < 0.05), while the serum IL-10 and TGF-β levels were significantly greater in Group D than in Group C (P < 0.05). Microscopy showed apparent loss of nasal mucosa cilia, increased number and enlargement of goblet cells, interstitial edema and submucous vascular dilation in Group C, while the pathological changes of nasal mucosa were alleviated in Group D relative to Group C. CONCLUSIONS E. granulosus HCFP has a protective activity against OVA-induced allergic rhinitis in mice.

Abstract
Ionic liquids (ILs) are used as detoxication agents for fermentation of lignin into ethanol because of their good applicability. However, the residual ILs may be toxic to the yeast. In order to improve the use of ILs for fermentation and protected environment, the toxicity of ILs with different carbon chain length to Pichia stipitis was studied in this paper. Four kinds of common imidazolium chloride ILs ([C4mim]Cl, [C6mim]Cl, [C8mim]Cl and [C10mim]Cl) were selected. ILs can inhibit the proliferation of Pichia stipitis and increase their mortality. Oxidative stress reaction occurred in the cells, and the activities of antioxidant enzymes are affected. Comparing with the integrated biomarker response (IBR) index, it was found that the toxicity increases with increasing chain length. ILs may enter cells by damaging cell membranes and reduce ethanol production by damaging organelles such as mitochondria. ILs caused wrinkles and dents on the surface of cells up to cell deformation and even rupture. The toxicity sequence was as follows: [C10mim]Cl> [C8mim]Cl>[C6mim]Cl>[C4mim]Cl. Due to this toxicity to Pichia stipitis, these compounds should be used carefully in the fermentation process and also to avoid toxic effects on other organisms in the environment.

Abstract
OBJECTIVE To analyze the components of proteins from Echinococcus granulosus cyst fluid using the shotgun method, and to identify the active components with potential regulatory effects for immune dysregulation diseases. METHODS The E. granulosus cyst fluid was collected aseptically from the hepatic cysts of patients with cystic echinococcosis, and characterized by liquid chromatography (LC) tandem mass spectrometry (MS/MS) following digestion with trypsin. The protein data were searched using the software MaxQuant version 1.6.1.0 and the cellular components, molecular functions, and biological processes of the identified proteins were analyzed using the Gene Ontology (GO) method. RESULTS The E. granulosus cyst fluid separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) had a relative molecular mass of 25 to 70 kDa. LS-MS/MS analysis identified 37 proteins, including 32 known proteins and 5 unknown proteins. At least 4 proteins were preliminarily found to exhibit potential regulatory effects for immune dysregulation diseases, including antigen B, glutathione-S-transferase (GST), thioredoxin peroxidase (TPX) and malate dehydrogenase (MDH). GO enrichment analysis showed that the identified proteins had 149 molecular functions and were involved in 341 biological processes. CONCLUSIONS E. granulosus cyst fluid has a variety of protein components, and four known proteins are preliminarily identified to be associated with immune dysregulation diseases.

Abstract
Water eutrophication caused by harmful algal blooms (HABs) occurs worldwide. It causes huge economic losses and has serious and potentially life-threatening effects on human health. In this study, the bacterium Raoultella sp. S1 with high algicidal efficiency against the harmful algae Microcystis aeruginosa was isolated from eutrophic water. The results showed that Raoultella sp. S1 initially flocculated the algae, causing the cells to sediment within 180 min and then secreted soluble algicidal substances that killed the algal cells completely within 72 h. The algicidal activity was stable across the temperature range -85.0 to 85.0 °C and across the pH range 3.00-11.00. Scanning electron microscopy (SEM) revealed the crumpling and fragmentation of cells algal cells during the flocculation and lysis stages. The antioxidant system was activated under conditions of oxidative stress, causing the increased antioxidant enzymes activities. Meanwhile, the oxidative stress response triggered by the algicidal substances markedly increased the malondialdehyde (MDA) and glutathione (GSH) content. We investigated the content of Chl-a and the relative expression levels of genes related to photosynthesis, verifying that the algicidal compounds attack the photosynthetic system by degrading the photosynthetic pigment and inhibiting the expression of key genes. Also, the results of photosynthetic efficiency and relative electric transport rate confirmed that the photosynthetic system in algal cells was severely damaged within 24 h. The algicidal effect of Raoultella sp. S1 against Microcystis aeruginosa was evaluated by analyzing the physiological response and photosynthetic system impairment of the algal cells. The concentration of microcystin-LR (MC-LR) slightly increased during the process of algal cells ruptured, and then decreased below its initial level due to the biodegradation of Raoultella sp. S1. To further investigate the algicidal mechanism of Raoultella sp. S1, the main components in the cell-free supernatant was analyzed by UHPLC-TOF-MS. Several low-molecular-weight organic acids might be responsible for the algicidal activity of Raoultella sp. S1. It is concluded that Raoultella sp. S1 has the potential to control Microcystis aeruginosa blooms.

Abstract
Different infiltration tests of permeable pavements provide different measurements of the infiltration capacity. These measurements often do not represent the fundamental flow properties, and hence cannot be directly compared. This presents an undesirable obstacle to the sharing of experience and to obtaining a better understanding of the infiltration performances of different permeable pavements. This problem is especially acute in the case of interlocking-block permeable pavements (IBPPs), owing to the presence of joints and the different sizes, shapes, and laying patterns of paving blocks. To overcome this problem, the present study proposed a new approach for evaluating the infiltration capacity of an IBPP while retaining the same measuring devices in use today. This approach makes use of a finite-volume computational fluid dynamic method to develop a simulation model for an infiltration test. Once calibrated to define the hydraulic parameters of the IBPP being tested, the model can be applied to calculate the saturated infiltration capacity of the IBPP under actual rainfall conditions. The model also permits the calculation of a conventional infiltration capacity measurement, such as the average infiltration rate in mm/h as measured by a particular infiltration test, or the time required to drain the tested water depth. Thus, the proposed approach provides a meaningful common basis for comparing the infiltration capacities of different permeable pavements, including porous asphalt, pervious concrete, and IBPPs.

Abstract
Ionic liquids (ILs1) which are called "green solvents", are used widely in the textile industry as adjuvants due to their many advantages. However, their persistent residues may cause ecotoxicity. The aim of the study is to explore the toxicity of different anions on imidazole ILs and their toxicological mechanism. For the experiments 1-butyl-3-methylimidazole tetrafloroborate ([C4mim]BF4) and 1- butyl -3-methylimidazolium chloride ([C4mim]Cl) were selected to study their toxic effects on Isatis tinctoria. ILs may affect the germination rate. Fresh weight, dry weight and Hill reaction activity decreased continuously with increasing of IL concentrations, showing an effect-dose relationship. Transmission electron microscopy (TEM) revealed that cell walls were fuzzy, starch granules had accumulated and the chloroplast structure was damaged. These changes will affected the function and electron transport efficiency of photosystemⅡ. Superoxide anion accumulation stimulated the activity of antioxidant enzymes (SOD, POD, CAT) and caused lipid peroxidation as well as an increased malondialdehyde content. ILs also reduced indirubin and total flavonoids contents, which reduced the pharmacological efficacy of Isatis tinctoria. This is demonstrated by three-dimensional fluorescence chromatogram. [C4mim]Cl was more toxic than [C4mim]BF4. ILs caused toxic effects to Isatis tinctoria. The ecological toxicity of ILs should be considered when using them as additives in the textile industry.

Abstract
BACKGROUND Visfatin acts as an oncogenic factor in numerous tumors through a variety of cellular processes. Visfatin has been revealed to promote cell migration and invasion in gastric cancer (GC). Snai1 is a well-known regulator of EMT process in cancers. However, the relationship between visfatin and snai1 in GC remains unclear. The current study aimed to explore the role of visfatin in GC. METHODS The RT-qPCR and western blot analysis were used to measure RNA and protein levels, respectively. The cell migration and invasion were tested by Trans-well assays and western blot analysis. RESULTS Visfatin showed upregulation in GC cells. Additionally, Visfatin with increasing concentration facilitated epithelial-mesenchymal transition (EMT) process by increasing E-cadherin and reducing N-cadherin and Vimentin protein levels in GC cells. Moreover, endogenous overexpression and knockdown of visfatin promoted and inhibited migratory and invasive abilities of GC cells, respectively. Then, we found that snai1 protein level was positively regulated by visfatin in GC cells. In addition, visfatin activated the NF-κB signaling to modulate snai1 protein expression. Furthermore, the silencing of snai1 counteracted the promotive impact of visfatin on cell migration, invasion and EMT process in GC. CONCLUSION Visfatin facilitates cell migration, invasion and EMT process by targeting snai1 via the NF-κB signaling, which provides a potential insight for the treatment of GC.

Abstract
High crash rates on horizontal curves during wet weather are a major road safety concern. Among the various causes of crashes on horizontal curves, wet-weather skidding is a major contributing factor. This study analyzed the mechanisms of three possible modes of vehicle skidding on horizontal curves based on theories of mechanics. The three modes of skidding analyzed were: (i) forward skidding of front steering wheel, (ii) sideway skidding of front steering wheel, and (iii) sideway skidding of rear wheel. The main objective was to provide useful information to researchers and practitioners in identifying the important factors that contribute to horizontal curve crashes. A computer simulation procedure was developed to evaluate the maximum safe vehicle speeds against the three modes of skidding on wet horizontal curved pavements. This offers a much improved method for skidding potential evaluation compared to the conventional approximate method using estimated coefficient of friction. The skidding potential of a vehicle is defined as the difference between its speed and the maximum safe speed against skidding. The smaller the difference, the higher is the skidding potential. The relative magnitudes of skidding potential for the three skidding modes were considered for different operating conditions. Different operating conditions were represented by different values of pavement curve radii, super-elevations, and wet-weather conditions represented by the thickness of pavement surface water-film. The analysis identified five key factors that affect the skidding potential of vehicles negotiating a horizontal curve. They are: vehicle speed, curve radius, superelevation, water film thickness and pavement skid resistance state.

Abstract
OBJECTIVE LncRNAs play a key role in the development and progression of prostate cancer. In this study, the effects of the lncRNA BLACAT1 in prostate cancer were investigated. PATIENTS AND METHODS Real-time PCR was used to detect the expression of BLACAT1 and miR-361 in prostate cancer tissues and adjacent normal tissues (n=25). The function of BLACAT1 was detected through proliferation assay and apoptosis assay. The interaction between BLACAT1 and miR-361 in prostate cancer was studied by luciferase assay, RNA immunoprecipitation assay and chromatin immunoprecipitation analysis were performed to detect the BLACAT1 binding proteins. The xenograft mice experiment was performed to further confirm the functional significance of lncRNA BLACAT1 in vivo. RESULTS In patient samples and prostate cancer cell lines, BLACAT1 was down-regulated and inversely proportional to DNMT1, HDAC1, EZH2, MDM2 and miR-361 expression. Treatment with 5-azacytidine and chidamide enhanced BLACAT1 expression and decreased the levels of miR-361. The BALCAT1 promoter was methylated in prostate cancer tissue and found to interact with miR-361 via luciferase assays. BLACAT1 bound to EZH2, DNMT1 and HDAC1. ChIP-seq analysis revealed that HDAC1 interacts with STAT3, while EZH2 interacts with the mitogen-activated protein kinase (MAPK) promoter. CONCLUSIONS Two regulatory axes of BLACAT1-EZH2-MAPK and BLACAT1-HDAC1-STAT3 were identified to be associated with the progression of prostate cancer. Both chidamide and 5-azacytidine represent promising therapeutic options in prostate cancer treatment.

Abstract
OBJECTIVE Epidural fibrosis represents a fatal stage of failed back surgery syndrome (FBSS) of known and idiopathic etiology, but no valid therapy is presently available. Previous evidence demonstrated that suberoylanilide hydroxamic acid (SAHA), a histone deacetylases inhibitor, has antifibrotic and anti-inflammatory potential. Current studies have proved that SAHA inhibits myofibroblast differentiation and increases fibroblast apoptosis to attenuate epidural fibrosis. The purpose of this study was to investigate the effect and mechanism of SAHA on repressing epidural fibrosis. PATIENTS AND METHODS First, the levels of acetylation of histone and α-tubulin in adult human fibroblasts (AHF) and human epidural fibroblasts (HEF) were analyzed following SAHA and transforming growth factor-β(TGF-β) treatment. Then, mRNA and protein obtained from human fibroblasts following TGF-β activation and SAHA treatment in vitro culture were used to test the influence of SAHA on the activation and apoptosis of fibroblasts, so as to further explore the related mechanism of SAHA. Then, a laminectomy model was established in rats to observe the therapeutic effect of SAHA on epidural scar tissue. RESULTS The present research proved that the increases of HDAC 3 and α-tubulin were observed in AHF and HEF after TGF-β administration, but SAHA decreased HDAC 3 and α-tubulin expressions. In addition, cell study demonstrated that SAHA inhibited fibroblast activation via decreasing TGF-β function and accelerated apoptosis by promoting cleaved-caspase-3. In the epidural fibrosis model, it was found that SAHA weakened scar hyperplasia and collagen deposition, and effectively inhibited the process of epidural fibrosis. CONCLUSIONS These results indicated that SAHA inhibited HDAC 3 expression, decreased TGF-β effect, and enhanced caspase-3 in fibroblasts, leading reduction of myofibroblast activation and apoptosis elevation. Hence, SAHA ameliorated epidural fibrosis development.

Abstract
OBJECTIVE To investigate the regulatory role of recombinant Trichinella spiralis cysteine protease inhibitors (rTs-Cys) in induction of polarization of bone marrow-derived macrophages (BMDMs) in vitro. METHODS BMDMs were captured and cultured in conditioned medium for 7 days. Then, mature BMDMs were harvested and assigned into four groups. Cells in Group A (negative control) were given 10 ng/mL IFN-γ combined with 100 ng/mL LPS, cells in Group B (positive control) were treated with IL-4 and IL-10 (at 10 ng/mL both), and cells in Group C (recombinant protein alone) were stimulated with 1 μg/mL rTs-Cys, while cells in Group D (protein co-culture) were simultaneously treated with 1 μg/mL rTs-Cys, 10 ng/mL IFN-γ and 100 ng/mL LPS. Cells and culture supernatant were collected 24 hour post-treatment, and the proportions of F4/80+, CD11b+, CD206+ and CD11c+ cells were detected by flow cytometry. The levels of interleukin IL-6 (IL-6), tumor necrosis factor-α (TNF-α), IL-10 and transforming growth factor-β (TGF-β) in the cell culture supernatant were measured by ELISA and the CD86+ and CD206+ phenotypes were identified by immunofluorescent staining. RESULTS Flow cytometry detected no significant difference in the proportion of F4/80+ CD11b+ CD11c+ cells among the four groups (F = 46.184, P < 0.001), and a lower proportion of F4/80+ CD11b+ CD11c+ cells was seen in groups C and D than in group A (all P values < 0.001). There was a significant difference in the proportion of F4/80+ CD11b+ CD206+ cells among the four groups (F = 11.032, P < 0.001), and a greater proportion of F4/80+ CD11b+ CD206+ cells was seen in groups C and D than in group A (all P values < 0.01). Immunofluorescent staining showed higher CD206+ expression and lower CD86+ expression in groups C and D than in Group A. There were significant differences in the IL-6 and (F = 3.950, P < 0.001) and TNF-α (F = 205.827, P < 0.001) levels in the cell culture supernatants among the four groups, and significantly lower IL-6 and TNF-α levels were measured in groups C and D than in Group A (both P < 0.05). There were significant differences in the IL-10 and (F = 8.274, P < 0.001) and TGF-β (F = 13.559, P < 0.01) levels in the cell culture supernatants among the four groups, and greater IL-10 and TGF-β levels were measured in Group C than in Group A (both P values < 0.01). In addition, the TGF-β level was significantly higher in Group D than in Group A (P < 0.05); however, there was no significant difference in the IL-10 level between groups D and A (P > 0.05). CONCLUSIONS rTs-Cys may induce the polarization of BMDMs to antiinflammatory M2 macrophages in vitro and inhibit the activation of M1 macrophages.

Abstract
The vitellogenin gene promoter (VgP) is an essential cis-regulatory element that plays a significant role in transcription of the vitellogenin (Vg) gene, leading to the production of yolk protein in insects, including lepidopterans. However, the function of VgP is still not clear in Plutella xylostella. Here, we cloned a 5.1 kb DNA fragment of the cis-regulatory region adjacent to the 5' end of the Vg gene of P. xylostella (PxVg). We identified two promoter sites in that 5' upstream sequence of PxVg and performed in vitro analysis of two promoter sequences (PxVgP1, 4.9 kb, and PxVgP2, 2.9 kb) in the embryonic cell line of P. xylostella. PxVgP2 exhibited higher enhanced green fluorescent protein (EGFP) expression, so PxVgP2 was used for in vivo analysis. Strong EGFP fluorescence was observed in adult females and the fat body of females, with low expression in embryos. Our results suggest that PxVgP is an important stage-, tissue- and sex-specific endogenous cis-regulatory element in P. xylostella.

Abstract
OBJECTIVE Rho-associated kinases (ROCKs) are recognized to be involved in many pathophysiological processes caused by hyperglycemia. We performed experiments to evaluate the effects of fasudil, the Rho/ROCK inhibitor, on preventing hepatic fibrosis in type 1 diabetic rats and to elucidate the underlying mechanisms. MATERIALS AND METHODS Sprague-Dawley (SD) rats were randomly divided into five groups: normal control (NC), untreated diabetic (DM), low-dose fasudil-treated (L-Fas), high-dose fasudil-treated (H-Fas) and captopril-treated (Cap) groups. Streptozotocin was injected to establish the diabetes model. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and inflammatory factors such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), were analyzed. Hematoxylin and eosin (HE) and Masson's trichrome staining were used for histological observations. The expression of transforming growth factor-β (TGF-β1), metalloproteinase-9 (MMP-9)/tissue inhibitor of metalloproteinase-1 (TIMP-1), collagen type Iα (Coll α1), nuclear factor-kappa B (NF-κB) and ROCK-1 were measured to investigate the mechanisms involved in fibrosis. RESULTS The DM group exhibited hepatic fibrosis with remarkable liver damage and inflammation reaction by the activation of the NF-κB pathway. Treatment with fasudil or captopril suppressed not only the inflammation reaction but also the accumulation of the extracellular matrix due to the downregulation of TGF-β1 and MMP-9/TIMP-1, which induces the amelioration of the liver fibrosis with diabetes. Furthermore, fasudil significantly attenuated the activation of ROCK-1 and NF-κB in the livers of diabetic rats. CONCLUSIONS These results suggest that fasudil exert anti-inflammation actions and markedly decrease the accumulation of extracellular matrix. Fasudil is a good candidate agent for treating hepatic fibrosis in diabetes.

Abstract
OBJECTIVE To investigate the protective effect of excretory-secretory protein (AES) from adult Trichinella spiralis on ovalbumin (OVA)-induced allergic rhinitis in mice. METHODS Eighteen female BALB/c mice were randomly divided into three groups, including the blank control group (Group A), OVA-induced rhinitis group (Group B) and AES treatment group (Group C). Mice in Group A were given PBS. Mice in Group B were intraperitoneally injected with antigen adjuvant suspension for systemic sensitization, once every other day for seven times; then, local excitation was intranasally induced with 5% OVA solution once a day for seven times to establish a mouse model of allergic rhinitis. In addition to induction of allergic rhinitis, mice in Group C were given 25 μg AES at baseline sensitization and local excitation. Following the final challenge, mice were observed for 30 min in each group, and the behavioral score was evaluated. The serum levels of IFN-γ, IL-4, IL-5, IL-10 and TGF-β were determined using an enzyme-linked immunosorbent assay in mice, and the pathological changes of mouse nasal mucosa were observed under a microscope. RESULTS There was a significant difference in the mouse behavioral scores among the three groups (F = 110.12, P < 0.01). The mouse behavioral score was significantly higher in Group B than in Group A (7.17 ± 0.75 vs. 1.33 ± 0.52, P < 0.01), and more remarkable pathological damages of mouse nasal mucosa were seen in Group B than in Group A, while the mouse behavioral score was significantly decreased in Group C than in Group B (P < 0.01), and the pathological damages of mouse nasal mucosa remarkably alleviated in Group C relative to Group B. There was a significant difference in serum IFN-γ level among the three groups (F = 7.50, P < 0.01) and the serum IFN-γ level in Group B was significantly lower than in group A and C (both P < 0.05). There were significant differences in serum IL-4 (F = 470.81, P < 0.01) and IL-5 levels (F =68.20, P < 0.01) among the three groups, and significantly greater serum IL-4 and IL-5 levels were detected in Group B than in Group A (P < 0.01), while significantly lower serum IL-4 and IL-5 levels were detected in Group C than in Group B (P < 0.01). There were significant differences in serum IL-10 (F = 174.91, P < 0.01) and TGF-β levels (F = 9.39, P < 0.01) among the three groups, and significantly greater serum IL-10 and TGF-β levels were seen in Group C than in Group B (both P < 0.05). CONCLUSIONS T. spiralis AES has a remarkable protective activity against OVA-induced allergic rhinitis in mice.

Abstract
BACKGROUND Spinosin, a major component of Samen Ziziphi spinosae, has been shown to modulate sedation and hypnosis; however, the underlying neuronal mechanisms of its stimulatory effects remain unclear. MATERIALS AND METHODS In the present study, we injected spinosin (15 mg/kg) or saline into mice, which were killed after 90 min. We isolated the brains, which were immunohistochemically stained for c-Fos as a biomarker for neuronal activation and assessed the expression profile of c-Fos in various sleep-arousal brain areas. RESULTS Our findings revealed that there were no statistically significant differences in the expression of c-Fos in the nucleus accumbens and ventrolateral preoptic area, the vertical limb of the diagonal band nucleus, horizontal limb of the diagonal band nucleus, ventral tuberomammillary nucleus, ventral tegmental area, and dorsal raphe nucleus relative to saline between saline and spinosin-treated mice. Unlike saline, spinosin markedly decreased c-Fos expression in the lateral hypothalamic area (LHA) as well as the locus coeruleus (LC). Compared to the saline injection, the application of spinosin also resulted in a marked decrease in c-Fos expression in the LHA orexin neurons. CONCLUSIONS These findings suggest that spinosin administration results in a restricted pattern of c-Fos expression within the LHA orexin neurons and the LC, suggesting that this particular neuronal inactivation contributes to sedation and hypnosis.

Abstract
Ionic liquids (ILs) are massively used in multiple fields of industry, and consequently, they have entered the environment and become potential threats to the respective ecosystems. In this paper, the toxicity of two different cationic types of ILs (1-hexyl-3-methyl pyridine chloride ([C6Py]Cl) and 1-hexyl-3-methyl imidazole chloride ([C6MIM]Cl)) to Chlorella pyrenoidosa (C. pyrenoidosa) was investigated. Growth inhibition increased with increasing ILs concentrations. C. pyrenoidosa showed a certain recovery at low ILs concentrations, the growth inhibition decreased from 6.13% to 1.57% of the control from 24 h to 96 h, respectively, in 0.5 mg/L [C6MIM]Cl treatment. However, growth inhibition was negatively related with exposure time at high concentrations, and the strongest toxic effects were observed after 48 h. The IC50 values (half inhibitory concentration) were 8.47, 6.65, 6.91 and 7.11 mg/L of [C6MIM]Cl, respectively, in 24, 48, 72, and 96 h, and were 9.05, 6.83, 7.79 and 8.14 mg/L of [C6Py]Cl, respectively. Chlorophyll content declined with higher concentrations of the ILs. The values of chlorophyll fluorescence parameters: the maximum effective quantum yield of photosystem II (PSII) (Fv/Fm), maximum quantum yield in PSII (Fv/F0), and photosynthetic efficiency in PSII (Y(II)), decreased, whereas the minimal fluorescence (F0) increased following the ILs treatment, indicating damage to the photosystem II. [C6MIM]Cl and [C6Py]Cl caused deformation of algae cells, plasmolysis, and damage of the cell membrane and cell wall, and affected organelle structure. Reactive oxygen species (ROS) concentrations increased with higher ILs concentrations from, and superoxide dismutase and catalase activity first increased and then decreased, indicating that the antioxidant defense system was activated to counteract ROS. ROS was the main stress in C. pyrenoidosa induced by ILs, and compared with [C6Py]Cl, [C6MIM]Cl were more toxic to C. pyrenoidosa.

Abstract
Many different test methods are used in practice to evaluate the surface infiltration performance of permeable pavements. This has led to inconsistency in reporting of test results. This study recognizes the differences in nature between a soil infiltration study and the surface infiltration evaluation of permeable pavements, and identifies the main issues associated with the current practice of surface infiltration testing. It proposes that hydraulic conductivity be adopted as the flow property for measurement and reporting instead of the commonly used infiltration rate. The advantages of measuring hydraulic conductivity are elaborated from both theoretical and practical implementation points of view. The theoretical merits of providing a consistent and integrated treatment of surface infiltration performance of a permeable pavement during the design, construction and maintenance phases are presented. The practical benefits are addressed from the following aspects: consistency between laboratory and field testing, uniformity in reporting of test measurements, rationality in construction quality control and acceptance checking, effectiveness in surface infiltration performance monitoring, and enhanced ability in implementing effective maintenance management. It is emphasized that the techniques and methods needed for measuring hydraulic conductivity of permeable pavement materials, for laboratory testing as well as on-site field testing, are already readily available and have been used by researchers and some practitioners for surface infiltration testing. Two falling-head test methods are recommended: one applies Darcy's law and determines hydraulic conductivity in the conventional way; another measures the time history of falling head and calculates hydraulic conductivity using a modified Darcy equation. It is also highlighted that the measurement of hydraulic conductivity offers a convenient platform for assessing the durability of a permeable pavement against clogging.

Abstract
BACKGROUND This study aims to describe the short-term reactogenicity of the AS03-adjuvanted H5N1 vaccine expressed through adverse events (AEs) and quality-adjusted life-day (QALD) scores. The AEs are likely to be short-term and therefore the quality of life (QoL) questionnaire, SF-36v2, was administered daily to record changes over seven days. A more sensitive application of this instrument should allow for a better understanding of short-term tolerability of adjuvanted vaccines. METHODS Participants (N = 50) received a 2-dose vaccination schedule. Solicited (collected daily: days 0 to 7 [post dose 1] and 21 to 28 [post dose 2]) and unsolicited (collected weekly until day 21) AEs were collected via diary cards. The QoL questionnaires were completed daily (days 0-6) and weekly (days 0, 6, 21, 27) after dose one. Questionnaire data were transformed into SF-6D scores to report QALDs. It was hypothesized post-hoc that the QALD and daily AEs scores should correlate if discrete QoL-changes were captured. RESULTS Pain (92%) and muscle ache (66%) were the most commonly reported solicited local and general AEs respectively, neither increased in intensity nor in frequency after dose 2. No safety concerns were identified during the study. A correlation between the daily AEs and QALD scores existed (correlation coefficient, - 0.97 (p < 0.001)). The impact of the AEs scores on the QALD was marginal (- 0.02 max for one day). CONCLUSION Similarly with other H5N1 studies, no safety concern was identified throughout the study. Some time-limited variations in QALD-scores were reported. Our results imply that daily administration of the SF-36v2 captures changes in QALD-scores. TRIAL REGISTRATION ClinicalTrials.gov .

Abstract
OBJECTIVE To investigate the role of long non-coding RNA Cancer Susceptibility Candidate 15 (CASC15) in cervical cancer and its potential molecular mechanism. PATIENTS AND METHODS The CASC15 expression was measured in cervical cancer tissues and cell lines by using quantitative Real-time polymerase chain reaction (qRT-PCR) analysis. Cell counting kit-8 (CCK8), flow cytometry analysis and transwell cell invasion assays were employed to detect the capacities of cell proliferation and cell invasion. Furthermore, Western blot analysis was applied to detected the E-cadherin and N-cadherin expression in EMT pathway. RESULTS We demonstrated that lncRNA CASC15 expression was higher in cervical cancer tissues compared to adjacent normal tissues. Higher lncRNA CASC15 expression associated with lymph node metastasis and FIGO stage. Moreover, our results showed that higher lncRNA CASC15 expression predicted poor prognosis of cervical cancer. Functional assays showed that knockdown of lncRNA CASC15 suppressed cell proliferation and cell cycle progression in cervical cancer. Moreover, we also found that knockdown of lncRNA CASC15 inhibited cell invasion ability and Epithelial-Mesenchymal Transition (EMT) signaling pathway by upregulating E-cadherin and downregulating N-cadherin expression in cervical cancer. CONCLUSIONS These results indicated that lncRNA CASC15 expression may be a prognostic biomarker and contributed to cell proliferation and invasion in cervical cancer.

Abstract
Objective: To investigate the clinical features of patients involved with both malignant tumors and neuromyelitis optica spectrum disorders (NMOSD). Methods: The clinical data of 473 patients with NMOSD admitted into the Third Affiliated Hospital of Sun Yat-sen University and the Department of Neurology, Affiliated Hospital of Guizhou Medical University from June 2012 to March 2017 were retrospectively analyzed. Eleven NMOSD patients complicated with malignant tumors were screened out (3 with breast cancer, 2 with cervical cancer, 2 with rectal cancer, 2 with leukemia, 1 with nasopharyngeal carcinoma, 1 with thyroid cancer). Fifty patients without NMOSD were included as controls. Results: Most of the NMOSD patients were complicated by low-moderately differentiated squamous cell carcinoma/adenocarcinoma, mainly seen in breast, reproductive system, digestive system and hematological system. In terms of sex ratio and autoantibodies, the NMOSD patients with and without malignant tumors showed no significant difference. However, comparing to the patients without malignant tumor, the ones with malignant tumor showed a tendency of lower rate of initial brain symptoms and relapse rate, while with older onset age, higher initial EDSS score, protein content in cerebrospinal fluid (CSF), higher rates of initial symptom resulted from the focus of posterior region of the medulla and of significant image focus. Of the 8 NMOSD patients who diagnosed as malignant tumors in our hospital, 2 with breast cancer and 1 with cervical cancer had a good prognosis (follow-up EDSS score <3). All the 3 patients received aggressive surgery and chemotherapy treatment. However, the other 5 patients had poor prognosis (follow-up EDSS score ≥3 points). All the 11 patients received anti-tumor therapy, 4 patients had first NMOSD attack after anti-tumor treatment and no relapse. Only one case from the remaining 7 patients had relapse; Among the 9 patients received immunosuppressive therapy, 7 patients had no relapse, and 8 cases maintained stable; while, among all the 9 patients received immunosuppressive agents and anti-tumor therapy, only one case had relapse. Conclusions: There are some differences in the clinical features between the NMOSD patients with malignant tumors and the NMOSD patients without malignant tumors. Immunosuppressive therapy can improve the prognosis of patients with NMOSD and tumor, without increasing the risk of malignant tumor. The pathological type, staging and antitumor therapy may influence the prognosis of NMOSD. NMOSD patients with malignant tumor could be treated with anti-tumor and immunosuppressive agents if needed.

Abstract
OBJECTIVES We carried out a randomized multicentre study in China to investigate whether the clofazimine would improve the efficacy of the standardized regimen in patients with multidrug-resistant tuberculosis (MDR-TB). METHODS Patients with MDR-TB managed in 17 TB specialist hospitals in China between September 2009 and September 2011 were randomly assigned to the treatment groups at enrolment. In the intervention group, 100 mg clofazimine per day was added to the standardized regimen. The primary outcome was the proportion of patients with successful outcomes. RESULTS From the 156 patients that were screened, 74 were assigned to the control group and 66 to the clofazimine group. Of the 66 cases analysed for clinical outcome in the clofazimine group, 36 patients were cured, and seven completed treatment, yielding a favourable outcome rate of 65.1%. The proportion of patients with favourable outcomes receiving the control regimen was 47.3% (35/74), which was significantly lower than that in the clofazimine group (p 0.034, relative risk 0.661, 95% CI 0.243-0.949). CONCLUSIONS The addition of clofazimine to the standard regimen improved the treatment of MDR-TB.
