Abstract
Approximately 89% of patients with Parkinson's disease (PD) suffer from dysarthria. Lee Silverman Voice Treatment (LSVT), a behavioral therapy, aims to improve speech and voice functions. The objective was to assess the effectiveness of LSVT compared with other/no speech interventions for dysarthria in patients with PD. Electronic databases, including PubMed, Embase and the Cochrane Library, were searched. The publication date of all included studies was before 6 March 2020. Only randomized controlled trials (RCTs) that evaluated the LSVT intervention compared with other/no speech intervention were considered. The data obtained from the included studies were described and the mean differences were calculated. Eight RCTs were included in this meta-analysis comparing LSVT with other/no speech interventions. In the comparison of LSVT versus no intervention, vocal intensity for sustained 'Ah' phonation, reading the 'Rainbow passage', monologue and describing a picture increased by 8.87, 4.34, 3.25 and 3.31 dB, respectively, after 1 month of therapy. Compared with the respiratory therapy group, the LSVT group also showed significant improvement in vocal intensity for sustained 'Ah' phonation, reading the 'Rainbow passage' and monologue immediately after treatment (13.39, 6.66 and 3.19 dB). Positive improvement still existed after 24 months. There was no difference in the therapeutic effect between face-to-face and online LSVT. The effectiveness of LSVT for dysarthria in patients with PD was verified in these trials. However, future RCTs with sufficient participants are essential to evaluate the effectiveness of LSVT for dysarthria.

Abstract
OBJECTIVES This study explored the factors influencing health behaviours during the coronavirus disease 2019 (COVID-19) outbreak in China. The impact of perceived stress and positive perception of interventions on health behaviours in China were assessed using the extended information-motivation-behaviour skills (IMB) model. STUDY DESIGN Cross-sectional survey. METHODS The Questionstar online survey tool was used to construct a structured questionnaire based on the IMB model. Between 14 and 22 February 2020, during the peak of COVID-19 epidemic in China, 2449 participants were recruited by snowball sampling on WeChat and Tencent QQ social media platforms in China. Data were collected through an online questionnaire, and structural equation modelling was performed to evaluate the extended IMB model. RESULTS Health behaviours were assessed using a scoring system (total score range: 8-40); the average health behaviour score in this study was 34.62 ± 4.44. The term 'health risk stress' refers to the impact that perceived stress has on health, and this was experienced by 39.9% of participants. Only 35.9% of participants answered all seven questions on COVID-19 information correctly. The final model showed that information, motivation, behavioural skills, heath risk stress and positive perception of interventions had significant direct effects on health behaviours. Health behaviours were positively associated with the positive perception of interventions but negatively associated with health risk stress. Behavioural skills had the greatest impact on health behaviours. CONCLUSIONS In the face of public health emergencies, the extended IMB model has been used as a theoretical framework to construct more effective interventions. The government should pay attention to publicity and guidance, strengthen positive interactions with the public and disclose relevant information in a timely manner to gain trust and to maintain the positive public perception of the interventions. In terms of health education, the government should focus on behavioural skills, promptly rectify ineffective prevention information and raise awareness about the disease to relieve stress and anxiety in the population.

Abstract
Gastric cancer (GC) is the second leading cause of cancer-associated deaths worldwide. Tanshinone IIA (TSN) is the pure extract from the root of red-rooted salvia and has been reported to inhibit the progression of GC cells. In this study, we investigated the microRNA (miRNA) mediated gene repression mechanism in TSN-administrated GC condition. The cell viability of GC was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. Cell migration and invasion were detected by transwell assays. The expression levels of epithelial-mesenchymal transition (EMT)-associated proteins (N-cadherin, vimentin, E-cadherin), High-mobility group box proteins 2 (HMGB2), β-catenin pathway-related proteins (β-catenin, c-myc, cyclin D1) were detected by western blot analysis in TSN/GC. The expression patterns of miR-874 and HMGB2 in GC were determined by quantitative real-time polymerase chain reaction (qRT-PCR). The potential miR-874-targeted HMGB2 was searched via bioinformatics methods and identified by dual-luciferase reporter assays, RNA immunoprecipitation (RIP) assays, and RNA pull-down assays. Xenograft tumor model was used to evaluate biological function in vivo. TSN limited the proliferation, migration, invasion, EMT progression in GC, and these results could be inverted by the silencing of miR-874. Moreover, the putative binding sites between miR-874 and HMGB2 were predicted by starBase software online. Meanwhile, enforced expression of HMGB2, negatively correlated with that of miR-874, reversed the positive effects of TSN administration on cells. Mechanically, TSN restrained the GC progression by miR-874/HMGB2/β-catenin signaling in vitro. Additionally, in vivo experiments confirmed that TSN inhibited the GC progression as well. TSN restrained the GC progression by regulating miR-874/HMGB2/β-catenin pathways in vitro and in vivo.

The CpxAR Two-Component System Contributes to Growth, Stress Resistance, and Virulence of Actinobacillus pleuropneumoniae by Upregulating wecA Transcription. Front Microbiol 2020; 11:1026.

Abstract
Actinobacillus pleuropneumoniae is the pathogen of porcine contagious pleuropneumonia. In A. pleuropneumoniae, the CpxAR two-component system is essential for fitness and growth. The O-antigen protrudes from the outer membrane to the exterior of the cell, and the outer membrane serves as a barrier that helps the bacteria to survive in harsh environments. WecA, a undecaprenyl phosphate GlcNAc-1-phosphate transferase, is involved in O-antigen repeating unit biosynthesis. In this study, we investigated the role of CpxAR in the expression of wecA in A. pleuropneumoniae. Our results revealed that CpxR positively regulates wecA expression by directly binding to the putative promoter region of wecA. Wild-type, ΔcpxAR, ΔwecA, and complemented strains were investigated under serum, oxidative, and osmotic stresses. The ΔcpxAR and ΔwecA strains were more susceptible to these stresses than the wild-type, but the complemented strains showed phenotypes similar to those of the wild-type. Mice infected with the ΔcpxAR and ΔwecA strains exhibited lower mortality and bacterial loads in the lung than those infected with the wild-type or complemented strains. This study reveals that the CpxAR two-component system contributes to A. pleuropneumoniae growth, stress resistance, and virulence, by upregulating expression of wecA. Our findings provide new insight into the pathogenesis of A. pleuropneumoniae.

Abstract
Bacillus cereus (B. cereus) is widely distributed in the environment. It is one of the most common opportunistic food-borne pathogens associated with food poisoning, not only being majorly reported to cause fatal infections of the gastrointestinal tract, but also responsible for abdominal distress and vomiting. The current study was undertaken to evaluate the biological characteristics and the genetic evolution of B. cereus isolated from infected organs of dead Elaphurus davidianus (E. davidianus). B. cereus was characterized through antibiotic sensitivity tests, mouse lethality assay, whole genome sequencing analysis, and genome annotation. The results revealed that the isolated B. cereus strain was highly resistant to rifampicin, lincomycin, sulfamethoxazole, erythromycin, and ampicillin, with a high pathogenicity phenotype. KEGG annotation revealed that "metabolic pathways" had the largest number of unigenes, followed by "biosynthesis of secondary metabolites" and "biosynthesis of antibiotics". GO analysis resulted in 8039 unigenes categorized. Meanwhile, 54,779 unigenes were annotated and grouped into 23 categories based on COG functional classifications. Moreover, one gene (codY) was found to be related to the host in conformity with the analysis done on PHI-base. Other tests led to the identification of 16 B. cereus virulence factor genes and five resistance types, with potential resistance against bacitracin, penicillin, and fosfomycin. We isolated a highly drug-resistant and pathogenic B. cereus strain from E. davidianus, showing that a variety of antimicrobial drugs should be avoided in clinical treatments. Furthermore, to the best of our knowledge, this is the first study to report whole genome sequencing of a emergence of food-borne B. cereus strain isolated from E. davidianus deer; it will be helpful to extensively investigate the genetic and molecular mechanisms of drug resistance and pathogenesis about B. cereus in both humans and animals.

Abstract
Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer, and epidemiological studies have suggested positive associations with iron and red meat intake. Rare mutations in genes involved in the hepcidin-regulating pathway are known to cause iron overload and hemochromatosis. We hypothesize that the hepcidin-regulating pathway as characterized by common variants from genome-wide association studies will be associated with PDAC. Methods: We conducted a large pathway-based meta-analysis of the hepcidin-regulating genes using the summary based adaptive rank truncated product (sARTP) method in 9,253 PDAC cases and 12,525 controls of European descent from the Pancreatic Cancer Cohort (PanScan) and the Pancreatic Cancer Case-Control (PANC4) consortia. Our analysis included 11 hepcidin-regulating genes (BMP2, BMP6, FTH1, FTL, HAMP, HFE, HJV, NRF2, SLC40A1, TFR1, TFR2) and adjacent genomic regions (20 kb upstream and downstream) with a total of 412 single-nucleotide polymorphisms (SNPs). We also conducted the sARTP with four iron status biomarkers (serum iron, transferrin, transferrin saturation, and ferritin, n = 23,986) using summary statistics from previous GWAS studies (Benyamin, et al. 2014) to examine if the hepcidin-regulating genes were also associated with these iron traits. The sARTP method combines SNP-level associations across variants in a gene or a pathway. Signals from up to five of the most associated SNPs for each gene studied were accumulated. Results: The hepcidin-regulating pathway was significantly associated with PDAC (P-value = 0.002) with the HJV, TFR2, and TFR1 genes contributing the most to the association (gene level P-values = 0.001, 0.014, and 0.019, respectively). The pathway associations were more significant in women than men. This pathway was also significantly associated with the four biomarkers of iron metabolism (P-values <1.5 × 10–7). Conclusions: Our results support that genetic susceptibility related to the hepcidin-regulating pathway is associated with PDAC and a potential role of iron metabolism in pancreatic carcinogenesis. Further studies are needed to evaluate the modifying effect of iron-rich foods and genetic susceptibility of this pathway and PDAC risk.

Abstract
BACKGROUND Precise classification of the hepatic artery is helpful for preoperative surgical planning in hepatobiliary-pancreatic surgery. However, the anatomy of hepatic arteries is variable. This study investigated anatomical variation using three-dimensional visualization and evaluation (3DVE) to develop a nomenclature system. METHODS The origin and course of the hepatic artery were tracked and analysed by using three-dimensional visualization of CT images acquired between 2013 and 2017. The new classification and nomenclature system, named CRL, was developed based on the origins of the common, right and left hepatic arteries. RESULTS Scans from 770 adults were evaluated. Preoperative 3DVE correlated better with surgical findings than the original CT images alone. Using the CRL classification system, hepatic arteries were divided into nine subtypes. Only 87·4-89·2 per cent of the hepatic arteries of 610 living-donor liver transplant donors were depicted in Michels', Hiatt's or Varotti's classification, compared with 100 per cent identified by the CRL classification. The CRL classification was validated against external data sets from previous studies, with 99·6-100·0 per cent of patients classified by the CRL system. CONCLUSION The CRL classification covers hepatic artery variants and may be used for planning liver surgery.

Abstract
Objective: To evaluate the effect of dexmedetomidine on lung injury and CCAAT/enhancer-binding protein homologous protein (CHOP) expression in elderly patients with lung cancer undergoing thoracoscopic lobectomy. Methods: A total of 120 elderly patients with lung cancer who underwent elective thoracoscopic lobectomy were selected from the Second Affiliated Hospital of Zhengzhou University from October 2018 to March 2019. The random phenotype was divided into dexmedetomidine group (group D, n=60) and control group (group C, n=60). The elapsed time before postoperative awake and spontaneous breathing recovery and agitation occurrence were recorded. The mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SPO(2)), oxygen partial pressure (PaO(2)), alveolar-arterial oxygen partial pressure difference[P(A-a)O(2)], end-tidal carbon dioxide partial pressure (P(ET)CO(2)), and airway pressure peak (P(peak)) were recorded before the anesthetic induction (T(0)), immediately after tracheal intubation (T(1)), immediately after unilateral pulmonary ventilation(T(2)), 1 hour after unilateral pulmonary ventilation (T(3)), immediately after bilateral pulmonary ventilation (T(4)), and at the end of surgery(T(5)). The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-8, IL-10, super oxide dismutase (SOD) and malondialdehyde (MDA)were compared at the time of T(0), T(1), T(2), T(3), T(4) and T(5) in two groups. The ratios of alveolar damage (IQA), apoptotic index (AI), and the expression of CHOP mRNA and their protein in lung tissue were detected. Results: The recovery time of conscious and spontaneous breathing in group D were significantly shorter than that in group C (P<0.05). The MAP and HR of the two groups at T(1)-T(5) were significantly lower than those at T(0)(P<0.05).The levels of P(peak) in group C at T(3)-T(5) was significantly higher than those in group D (P<0.05). The SpO(2) values in the group D at T(1)-T(5) were significantly higher than those in group C (P<0.05). The P(A-a)O(2) values in the group D at T(1)-T(5) was significantly lower than those in group C (P<0.05).The levels of IL-6, IL-8 and MDA in group D at T(1)-T(5) were significantly lower than those in group C(P<0.05). The levels of IL-10 and SOD in group D at T(1)-T(5) were significantly higher than those in group C (P<0.05). The values of IQA, AI, and the expression of CHOP mRNA and their protein in the two groups at T(4) were significantly higher than those at T(2) (P<0.05). The values of IQA, AI, and the expression of CHOP mRNA and their protein in group D at T(4) were significantly lower than those in group C (P<0.05). Conclusions: Dexmedetomidine could attenuate the extent of lung injury in elderly patients with lung cancer undergoing thoracoscopic lobectomy. The pulmonary protective mechanism could be related to the inhibition of inflammatory factors in dexmedetomidine, improving oxidative stress and reducing Chop-mediated apoptosis of lung tissue by the protein.

Abstract
Pulmonary arterial hypertension (PAH), also known as broilers ascites syndrome, is characterized by hypoxia, pulmonary artery pressure, and right heart failure. However, less information is available about the molecular mechanisms of PAH. We evaluated the mediation of calcium-sensing receptor by inducing hypoxia for the possible proliferation of pulmonary artery smooth muscle cells via the G protein pathway. For this purpose, we used an in vitro trial of chicken cell culture and confirmed our results by using immunohistochemistry, immunofluorescence staining, quantitative real-time polymerase chain reaction assay, and Western blotting analysis. Our results showed that the mRNA and protein expression levels of calcium-sensing receptor (CaSR) were significantly upregulated in cells when co-incubated with CaCl2. However, the levels of mRNA and protein were obviously decreased when supplemented with blocking agents (NiCl2, 2-APB, and D609). Furthermore, the experimentally induced hypoxia also upregulated the expression of CaSR gene as compared to CaSR gene expression in control cells. Together, these results indicate that hypoxia plays an important role in the expression of CaSR gene in pulmonary artery smooth muscle cells and reveals new targets for the CaSR excited hypothesis to prevent and control PAH in chickens.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy of the International Ovarian Tumor Analysis (IOTA) Assessment of Different NEoplasias in the adneXa (ADNEX) model in the preoperative diagnosis of adnexal masses using data from a gynecological oncology center in China. METHODS This was a single-center, retrospective diagnostic accuracy study based on ultrasound data collected prospectively, between May and December 2017, from 278 patients with at least one adnexal (ovarian, paraovarian or tubal) mass. Clinical and pathologic information, serum CA 125 level and ultrasonographic findings were collected. All patients underwent surgery and the histopathological diagnosis was used as reference standard. The final diagnosis was classified into five tumor types according to the ADNEX model: benign ovarian tumor, borderline ovarian tumor (BOT), Stage-I ovarian cancer (OC), Stages-II-IV OC and ovarian metastasis. Receiver-operating characteristics (ROC) curve analysis was used to evaluate the diagnostic accuracy of the ADNEX model, with and without inclusion of CA 125 level in the model. RESULTS Of the 278 women included, 203 (73.0%) had a benign ovarian tumor and 75 (27.0%) had a malignant ovarian tumor, including 18 (6.5%) with BOT, 17 (6.1%) with Stage-I OC, 32 (11.5%) with Stages-II-IV OC and eight (2.9%) with ovarian metastasis. The performance of the IOTA ADNEX model was good for discriminating between benign and malignant tumors, with an area under the ROC curve (AUC) of 0.94 (95% CI, 0.91-0.97) when CA 125 was included in the model and AUC of 0.93 (95% CI, 0.90-0.96) without CA 125. The AUC values of the model including CA 125 ranged between 0.61 and 0.99 for distinguishing between the different types of tumor, and it showed excellent performance in discriminating between a benign ovarian tumor and Stages-II-IV OC, with an AUC of 0.99 (95% CI, 0.97-1.00). The performance of the model was less effective at distinguishing between BOT and Stage-I OC and between Stages-II-IV OC and ovarian metastasis, with AUC values of 0.61 (95% CI, 0.43-0.77) and 0.78 (95% CI, 0.62-0.90), respectively. Although inclusion of CA 125 did not alter the performance of the ADNEX model in discriminating between benign and malignant lesions (AUC of 0.94 and 0.93 with and without CA 125 level, respectively; P = 0.54), the inclusion of CA 125 in the model improved its performance in discriminating between Stage-I OC and Stages-II-IV OC (AUC increased from 0.81 to 0.92; P = 0.04) and between Stages-II-IV OC and metastatic cancer (AUC increased from 0.58 to 0.78; P = 0.01). CONCLUSIONS The IOTA ADNEX model showed good to excellent performance in distinguishing between benign and malignant adnexal masses and between the different types of ovarian tumor in a Chinese setting. Based on our findings, the ADNEX model has high value in clinical practice and can aid in the preoperative diagnosis of patients with an adnexal mass. Copyright © 2019 ISUOG.

Abstract
Objective: To analyze the prevalence of pneumoconiosis and civil aid and medical care among Xiangyang-Chongqing railway construction workers in Chongqing from 2011 to 2018, so as to provide scientific basis for prevention and control of pneumoconiosis. Methods: The Chongqing database of Xiangyang-Chongqing railway construction workers cases from 2011 to 2018 were subjected to systematic collected. SPSS 18.0 was adopted for statistical description and analysis. Results: From 2011 to 2018, a total of 7031 silicosis cases were diagnosed, and 5827 cases were existed, including 4056 cases of stage I, 1491 cases of stage II, and 280 cases of stage III. The cases were concentrated in the area along the southwest to northeast of Chongqing. The diagnosis age of silicosis patients was mainly 60~64 years old (69.73%) . Most silicosis cases were the drill workers and the stone workers. The exposure time of silicosis patients was short and concentrated in 3 years. The 5827 cases of pneumoconiosis in the Xiangyang-Chongqing railway were all treated with special civil aid and medical care for pneumoconiosis in the Xiangyang-Chongqing railway. Conclusion: The prevalence of silicosis among workers who participated in Xiangyang-Chongqing railway construction remained serious. Civil aid and medical care covers all silicosis patients. Occupational health surveillance for silicosis and assistance should be carried out in these workers.

Abstract
Objective: To analyze the prevalence of pneumoconiosis and assistance guarantee of the migrant workers of the district in Chongqing from 2006 to 2017, so as to provide scientific basis for prevention and control of pneumoconiosis of the migrant workers. Methods: The database of new pneumoconiosis cases of the migrant workers and assistance guarantee of the district in Chongqing from 2006 to 2017 were subjected to systematic arrangement. SPSS 18.0 was adopted for statistical description and analysis. Results: From 2006 to 2017 a total of 2188 new cases of pneumoconiosis were diagnosed, including I (917, 41.91%) , II (1003, 45.84%) , III (268, 12.25%) . Most of new cases of pneumoconiosis were silicosis. The median length of seniority was 6 years. The mean diagnostic age was 44.25. Significant difference was found in diagnosis age between different stages (F=3.161, P=0.043) . 98.77% of migrant workers had no units. There were 5.07% of migrant workers who took out industrial injury insurance, 14.58% receiving civil aid, 31.12% receiving aid from poverty alleviation, and 93.46% participating medical insurance. Conclusion: The prevalence of pneumoconiosis of the migrant workers of the district in Chongqing was serious. The prevention and control of pneumoconiosis should be enhanced to reduce the harm of pneumoconiosis of the migrant workers in Chongqing.

Abstract
Objective: To analyze the infection status and recombination of Norovirus in patients with acute gastroenteritis in Ningxia. Methods: The specimens of 10 sentinel hospitals in Ningxia were collected from 2016 to 2017. Real-time quantitative PCR was used for nucleic acid detection. GⅡ-positive samples were amplified by RT-PCR for the RdRp and Capsid regions, then sequenced and genotyped. Evolution analysis was performed using software such as MEGA-X, and recombination analysis was performed using Simplot 3.5.1 and RDP4. Results: The age of the 2 334 cases was 1.42 (0.68, 7.69) years old, 1 133 cases in 2016 and 1 201 cases in 2017, 1 343 and 991 cases for males and females respectively. The positive rate of Norovirus GⅠ genogroup was 0.86% (20/2 334), and GⅡ genogroup was 14.82% (346/2 334). A total of 78 recombinant strains were sequenced and 12 recombinant types were found. GⅡ.Pe/GⅡ.4Sydney_2012 and GⅡ.P12/GⅡ.3 were the main epidemic strains, accounting for 35.90% (28 strains) and 32.05% (25 strain) respectively, followed by GⅡ.P16/GⅡ.2 accounting for 12.82% (10 strains). Among them,GⅡ.P7/GⅡ.6 (2 strains), GⅡ.P12/GⅡ.3 (6 strains), GⅡ.P16/GⅡ.1 (2 strains), GⅡ.P16/GⅡ.2 (5 strains), GⅡ.Pe/GⅡ.4 (7 strains) were detected for the first time in Ningxia. Recombinant strains were all intergenotype recombination, and the recombination breakpionts were all located within ORF1. Conclusion: Norovirus infection in Ningxia area was mainly in GⅡ genogroup from 2016 to 2017, and most of them were recombinant strains. GⅡ.Pe/GⅡ.4Sydney_2012 and GⅡ.P12/GⅡ.3 were the main epidemic strains, followed by GⅡ.P16/GⅡ. 2.

Abstract
OBJECTIVE To evaluate the impact of systemic lupus erythematosus (SLE) on health-related quality of life (HRQoL) assessed with SF-36 and explore factors associated with HRQoL in SLE patients. METHODS A random-effect meta-analysis was performed to calculate extracted data. Sensitivity and subgroup analyses were performed to distinguish sources of heterogeneity. RESULTS A total of 36 articles were finally included in this meta-analysis, including 6510 patients. The pooled mean scores of SF-36 physical component summary and mental component summary were 46.10 (95% confidence interval (CI): 43.09-49.10) and 50.37 (95% CI: 47.78-52.87), respectively. Spearman's correlation analysis found that mean age, proportion of female participants, and publication decades were negatively associated with some of the SF-36 domains. Sample size and SLEDAI were positively associated with some of the SF-36 domains. Patients with SLE have lower HRQoL in comparison to the general population. CONCLUSIONS SLE has a significant impact on HRQoL, which proves that the necessity of improving HRQoL in SLE patients cannot be ignored. Measuring HRQoL should be considered as an indispensable part of the overall evaluation of health conditions of SLE patients.

Abstract
Background SsPepO is an important virulence in Streptococcus suis. Methods In this study, we showed that SsPepO contributes to the human fibronectin-mediated adherence ability of S. suis to human brain microvascular endothelial cells. Results The addition of an antifibronectin antibody or an arginine-glycine-aspartic acid peptide that blocks fibronectin binding to integrins significantly reduced adherence of the wild-type but not the SspepO mutant strain, indicating the importance of the SsPepO-fibronectin-integrin interaction for S. suis cellular adherence. Conclusions By analyzing Evans blue extravasation in vivo, we showed that the interaction between SsPepO and human fibronectin significantly increased permeability of the blood-brain barrier. Furthermore, the SspepO mutant caused lower bacterial loads in the brain than wild-type S. suis in models of meningitis. These data demonstrate that SsPepO is a fibronectin-binding protein, which plays a contributing role in the development of S. suis meningitis.

Abstract
Streptococcus suis is an important pathogen in pigs and can also cause severe infections in humans. However, little is known about proteins associated with cell growth and pathogenicity of S. suis. In this study, a guanosine triphosphatase (GTPase) MnmE homolog was identified in a Chinese isolate (SC19) that drives a tRNA modification reaction. A mnmE deletion strain (ΔmnmE) and a complementation strain (CΔmnmE) were constructed to systematically decode the characteristics and functions of MnmE both in vitro and in vivo studies via proteomic analysis. Phenotypic analysis revealed that the ΔmnmE strain displayed deficient growth, attenuated pathogenicity, and perturbation of the arginine metabolic pathway mediated by the arginine deiminase system (ADS). Consistently, tandem mass tag -based quantitative proteomics analysis confirmed that 365 proteins were differentially expressed (174 up- and 191 down-regulated) between strains ΔmnmE and SC19. Many proteins associated with DNA replication, cell division, and virulence were down-regulated. Particularly, the core enzymes of the ADS were significantly down-regulated in strain ΔmnmE. These data also provide putative molecular mechanisms for MnmE in cell growth and survival in an acidic environment. Therefore, we propose that MnmE, by its function as a central tRNA-modifying GTPase, is essential for cell growth, pathogenicity, as well as arginine metabolism of S. suis.

Abstract
Objectives: To summarize the computed tomography angiography(CTA) features of Dieulafoy disease of the bronchus. Methods: The clinical, imaging and pathological data of Dieulafoy disease of the bronchus diagnosed in our hospital from July 4, 2010 to June 20, 2016 were retrospectively analyzed, and the CTA imaging features of the abnormal bronchial arteries were summarized. Results: There were 6 cases of bronchial Dieulafoy disease, 5 males and 1 female, with an average age of (55±15) years. Three cases had smoking history, and 2 cases had underlying diseases such as tuberculosis and acute myeloid leukemia. The common manifestations were hemoptysis, fever and pneumonia. Three patients got CTA examination, and bronchial arteries of Dieulafoy disease of the bronchus were circuitous and dilated, with the vascular diameter lager than 2 mm, no gradual narrowing but sudden truncation. Some circuitous vessels went into bronchial lumen as nodules. The bronchoscopy biopsy of 2 cases of bronchial nodules led to severe hemorrhage, with one death and one survival by successful management. Conclusions: Bronchial arteries of Dieulafoy disease of the bronchus were circuitous and dilated, and some circuitous vessels went into bronchial lumen as nodules, this demonstration can be used to diagnose Dieulafoy disease of the bronchus. For patients with hemoptysis, bronchial biopsy should only be performed after CTA examination if this disease is suspected.

Abstract
A new relativistic vortex cutter driven by the Laguerre-Gaussian (LG) mode is carried out for the first time in three-dimensional particle-in-cell simulations. Studies show that the electric fields periodically concentrate and emanate within every laser wavelength for the reflected circularly polarized LG_{p}^{l} (p=0, l=1, σ_{z}=-1) laser, which works just like a vortex cutter, resulting in a relativistic ultrashort collimated electron cluster with a constant period in space. A single particle model is given and verifies that the cluster formation has a close relation with the parameters of orbital angular momentum (l) and spin angular momentum (σ_{z}). Such a relativistic vortex cutter potentially can be applied for the accelerator, generating high-flux particle and coherent radiation sources, and so on.

Abstract
Type II toxin-antitoxin (TA) systems are highly prevalent in bacterial genomes and have been extensively studied. These modules involve in the formation of persistence cells, the biofilm formation, and stress resistance, which might play key roles in pathogen virulence. SezAT and yefM-yoeB TA modules in Streptococcus suis serotype 2 (S. suis 2) have been studied, although the other TA systems have not been identified. In this study, we investigated nine putative type II TA systems in the genome of S. suis 2 strain SC84 by bioinformatics analysis and identified three of them (two relBE loci and one parDE locus) that function as typical type II TA systems. Interestingly, we found that the introduction of the two RelBE TA systems into Escherichia coli or the induction of the ParE toxin led to cell filamentation. Promoter activity assays indicated that RelB1, RelB2, ParD, and ParDE negatively autoregulated the transcriptions of their respective TA operons, while RelBE2 positively autoregulated its TA operon transcription. Collectively, we identified three TA systems in S. suis 2, and our findings have laid an important foundation for further functional studies on these TA systems.

Abstract
Mycoplasma hyopneumoniae is the causative agent of porcine enzootic pneumonia (EP) and responsible for major economic losses in global swine industry. After colonization of the respiratory epithelium, M. hyopneumoniae elicits a general mucociliary clearance loss, prolonged inflammatory response, host immunosuppression and secondary infections. Until now, the pathogenesis of M. hyopneumoniae is not completely elucidated. This present study explores the pathogenicity of mhp390 (P68, a membrane-associated lipoprotein) by elucidating its multiple functions. Microtitrer plate adherence assay demonstrated that mhp390 is a new cilia adhesin that plays an important role in binding to swine tracheal cilia. Notably, mhp390 could induce significant apoptosis of lymphocytes and monocytes from peripheral blood mononuclear cells (PBMCs), as well as primary alveolar macrophages (PAMs), which might weaken the host immune response. In addition, mhp390 contributes to the production of proinflammatory cytokines, at least partially, via the release of IL-1β and TNF-α. To the best of our knowledge, this is the first report of the multiple functions of M. hyopneumoniae mhp390, which may supplement known virulence genes and further develop our understanding of the pathogenicity of M. hyopneumoniae.
