Abstract
With the increasing requirements for clean and effective utilization, coal swelling pretreatment provides a good theoretical basis for coal molecular structure, application in coal pyrolysis, and liquefaction. Ionic liquids containing magnetic anionic groups were designed, synthesized, and used as solvents to study the effect on swelling pyrolysis performance. Studies have shown magnetism enhancement with the growth of alkyl chains. The growth of the MIL alkyl side chain made the modification effect of coal more obvious, and the swelling degree showed a trend of first increasing and then decreasing with the increase of temperature and time, and at the temperature of 35 °C, the swelling degree is the largest when the modification time is 8 h. Pyrolysis experiments show that magnetic ionic liquid (MIL) pretreatment can significantly reduce the temperature at the maximum weight loss of coal and increase the tar content of pyrolysis, indicating that MIL plays a catalytic cracking role in coal pyrolysis.

Abstract
In the quest to build general-purpose photonic quantum computers, fusion-based quantum computation has risen to prominence as a promising strategy. This model allows a ballistic construction of large cluster states which are universal for quantum computation, in a scalable and loss-tolerant way without feed forward, by fusing many small n-photon entangled resource states. However, a key obstacle to this architecture lies in efficiently generating the required essential resource states on photonic chips. One such critical seed state that has not yet been achieved is the heralded three-photon Greenberger-Horne-Zeilinger (3-GHZ) state. Here, we address this elementary resource gap, by reporting the first experimental realization of a heralded 3-GHZ state. Our implementation employs a low-loss and fully programmable photonic chip that manipulates six indistinguishable single photons of wavelengths in the telecommunication regime. Conditional on the heralding detection, we obtain the desired 3-GHZ state with a fidelity 0.573±0.024. Our Letter marks an important step for the future fault-tolerant photonic quantum computing, leading to the acceleration of building a large-scale optical quantum computer.

Abstract
Background Approximately 20% of patients with ulcerative colitis will experience an acute severe exacerbation requiring hospitalization. Acute severe ulcerative colitis (ASUC) is a medical emergency associated with significant morbidity and a mortality rate of 1%. Timely initiation of treatment and assessment of clinical response is critical in the management of ASUC. With an aim to reduce treatment variability and improve outcomes, multiple gastrointestinal societies have published guidelines highlighting recommendations for optimal care in ASUC. It remains unclear how closely these guidelines are implemented in clinical practice. Measuring adherence to these recommended processes of care may act as a surrogate measure for quality of care and a way to indirectly evaluate outcomes in the management of patients with ASUC. Studies have shown that even amongst experienced providers practice pattern variability exists. Identifying significant variations in the management of patients with ASUC will highlight where improvement in guideline dissemination and greater adherence is required. Purpose We sought to evaluate how quality of care indicators varied across 7 hospital sites for patients admitted ASUC in the Greater Toronto Area. Method Using GEMINI, a research collaborative that collects and analyses data from inpatient admissions at 7 Toronto area hospitals, we identified patients admitted to hospital with ASUC from June 2016-December 2019. Hospital sites were further categorized into 3 hospital types; 1 IBD specialty centre (ISC), 3 other academic centres (AC) and 3 community centres (CC). Process measures assessed included proportion tested for C-reactive protein at baseline and following treatment initiation, duration of corticosteroid use, timing and initiation of biologic agents, rates of venous thromboembolism prophylaxis and opioid use. Outcome measures included hospital length of stay, rates of colectomy and mortality. Result(s) 765 hospitalizations were included in the study; 320 occurring at ISC, 308 at AC and 137 at CC. Corticosteroid use on admission were highest at the ISC at 78% compared to 64% at AC and 63% at CC (p <0.001). Among those who received steroids on admission, 47% of patients remained on intravenous corticosteroids for at least 5 days in the ISC compared to 39% in AC and 75% in CC (p< 0.001). Initiation of biologic rescue therapy was highest at the ISC occurring in 37% of hospitalizations compared to 22% in AC and 23% in CC (p<0.001). In addition, VTE prophylaxis rates were highest at the ISC at 83% followed by 60% in AC and 45% in CC (p<0.001). Rates of colectomy were highest at ISC (12% of hospitalizations vs. 7% in AC). Conclusion(s) Greater adherence to indicators of quality of care were seen at the ISC compared to ACs and CCs, although patient outcomes assessed were not clearly different between sites. Further strategies are required to improve adherence to markers of quality care for patients admitted with ASUC.

Abstract
Municipal sludge (MS) is used to prepare coal water slurry (CWS). This practice is beneficial for resource utilization and reduces treatment costs and environmental pollution. In this study, alkali-modified municipal sludge (AMS) was prepared with Ca(OH)2 as modifier and mixed with coal to produce AMS-CWS. The effect and mechanism of MS and AMS on slurry ability, stability, and combustion characteristics of the CWS were explored. The results of the pulping experiments showed that the slurry concentration of the AMS-CWS was approximately 10% greater than that of MS-CWS. The water separation rates of MS-CWS and AMS-CWS were 5% and 5.26%, respectively, which were 13.62% and 13.36% less than that of CWS (18.62%). The zeta potential experiments verified these results. Combustion performance research shows that both MS and AMS have positive effects on combustion performance. The results of the contact angle experiments showed that the hydrophobicity of AMS was enhanced, which was beneficial for improving the pulping capacity of MS-CWS.

Abstract
In this study, the effect of a bio-based environment-friendly surfactant, cardanol polyoxyethylene ether (BGF), on the wettability of the surface of low-rank coal (LRC) and its mechanism were studied. The adsorption experiment showed that the adsorption of the surfactant conformed to the Langmuir adsorption model and the pseudo-second-order kinetic model. The adsorption was mainly affected by hydrogen bonding, and the adsorption rate was affected by intraparticle diffusion and liquid film diffusion. The wettability experiment showed that the influence of BGF on the wettability of the surface of LRC followed the given order: BGF-7 > BGF-10 > BGF-15. The investigation of adhesion work showed that the adhesion work and the stability of the coal-water system decreased after adsorption. Fourier transform infrared and X-ray photoelectron spectroscopy analyses showed that after adsorption, the peak strength of vinyl ether, the content of elemental carbon, and the content of C-C/C-H groups increased.

Abstract
Background Mediastinal cysts (MCs) can be misdiagnosed as mediastinal tumors (MTs) such as thymomas on the basis of radiological examinations, including computerized tomography (CT) and magnetic resonance imaging (MRI). Our study aimed to determine the utility of a radiomics model combined with eXtreme Gradient Boosting (XGBoost) for diagnosing anterior mediastinal masses. Methods Patients with anterior mediastinal lesions admitted to Shanghai Pulmonary Hospital between October 2014 and January 2018 were enrolled in the study. Mediastinal lesions were sketched on each CT image frame using OsiriX workstation. The study involved a total of 592 patients (289 male/303 female; age range, 18–83 years) with anterior mediastinal lesions (322 MCs and 270 MTs). Previously collected training data was used to build an XGBoost model to classify MCs and MTs, and a prospectively collected training dataset and external data from Huashan Hospital were used for validation. The SHapley Additive exPlanations (SHAP) method was used to help understand the complex model. Results The XGBoost model was established using 107 selected radiomic features, and an accuracy of 0.972 [95% confidence interval (CI): 0.948–0.995] was achieved compared to 0.820 for radiologists. For lesions smaller than 2 cm, XGBoost model accuracy reduced slightly to 0.835, while the accuracy of radiologists was only 0.667. The model accuracy also achieved 0.910 when validated using an independent external dataset containing 87 cases. SHAP analysis suggested the 90% percentile Hounsfield unit value as a promising diagnostic parameter. Conclusions Our combined radiomics and XGBoost model significantly increased the accuracy of distinguishing between MCs and MTs compared to the level of accuracy obtained by radiologists.

Abstract
1. The major histocompatibility complex (MHC) is a highly polymorphic region of the genome essential to immune responses and animal health. However, avian MHC genetic structure is different from that of mammals. In this study, the structure and expression of Korean quail MHC class I gene was analysed.2. The quail MHC gene consisted of eight exons and seven introns. The open reading frame of the cDNA was 353 amino acids, and the molecular weight was about 38.91 kDa. Exons 1 and 2 coded for leading peptides and alpha 1 regions, respectively. Exons 3 and 4 encoded alpha 2 and alpha 3 regions. Exons 5 to 8 coded for connecting peptides and transmembrane regions/cytoplasmic regions (TM/CY). The Korean quail MHC class I amino acid sequence shared 87% to 99% homology with Japanese quail and 71% to 75% with chicken. The amino acid shared 40% and 43% homology with humans and mice, respectively.3. Real-time quantitative PCR showed that MHC-I was highly expressed in immune tissues such as the bursa of Fabricius. Moreover, the constructed evolutionary tree was consistent with accepted evolutionary pathways.4. MHC-I is closely related to the host's immune system, and these findings may help to better understand the role of Korean quail MHC-I in the immune system.

Abstract
OBJECTIVE We herein demonstrate the efficacy of PICC placement through a superficial femoral vein in patients with superior vena cava syndrome using ultrasound guidance and electrocardiographic localization. The treatment of PICC disconnection was also discussed. METHODS The study enrolled 51 patients with superior vena cava syndrome. Ultrasound-guided technology and ECG positioning technology are employed to help these patients in catheterization. The puncture time, the number of punctures, and catheter tip position were recorded. The patient was followed up for at least 2 years. The complications and treatment during follow-up were recorded. RESULT The average puncture time was 32.13 ± 3.91 min. A total of 49 patients were successfully punctured once, while 2 patients failed in the first puncture. The main reason for puncture failure is that the inability of a guide wire to pass through. After the nurse removed the needle and pressed the puncture point until no rebleeding occurred, the puncture above the original puncture point was successful. X-ray examination revealed that the catheter tip was located in the inferior vena cava, above the diaphragm, near the right atrium. The success rate of catheterization was 100%. The visual analog scale (VAS) score was (2.44 ± 0.73) at the time of puncture, which was tolerable during the operation, and the patient did not complain of obvious pain following the operation. One patient developed complications of broken tube half a year after the puncture. Interventional physicians utilized angiography to locate the broken catheter. CONCLUSION It is safe and feasible to place PICC through a superficial femoral vein under ultrasound combined with ECG positioning technology in patients with superior vena cava syndrome.

Abstract
BACKGROUND Prolonged hospitalization and immobility of critical care patients elevate the risk of long-term physical and cognitive impairments. However, the therapeutic effects of early mobilization have been difficult to interpret due to variations in study populations, interventions, and outcome measures. We conducted a meta-analysis to assess the effects of early mobilization therapy on cardiac surgery patients in the intensive care unit (ICU). METHODS PubMed, Excerpta Medica database (EMBASE), Cumulative Index of Nursing and Allied Health Literature (CINAHL), Physiotherapy Evidence Database (PEDro), and the Cochrane Library were comprehensively searched from their inception to September 2018. Randomized controlled trials were included if patients were adults (≥18 years) admitted to any ICU for cardiac surgery due to cardiovascular disease and who were treated with experimental physiotherapy initiated in the ICU (pre, post, or peri-operative). Data were extracted by 2 reviewers independently using a pre-constructed data extraction form. Length of ICU and hospital stay was evaluated as the primary outcomes. Physical function and adverse events were assessed as the secondary outcomes. Review Manager 5.3 (RevMan 5.3) was used for statistical analysis. For all dichotomous variables, relative risks or odds ratios with 95% confidence intervals (CI) were presented. For all continuous variables, mean differences (MDs) or standard MDs with 95% CIs were calculated. RESULTS The 5 studies with a total of 652 patients were included in the data synthesis final meta-analysis. While a slight favorable effect was detected in 3 out of the 5 studies, the overall effects were not significant, even after adjusting for heterogeneity. CONCLUSIONS This population-specific evaluation of the efficacy of early mobilization to reduce hospitalization duration suggests that intervention may not universally justify the labor barriers and resource costs in patients undergoing non-emergency cardiac surgery.

Abstract
INTRODUCTION Extended sleeve lobectomy (ESL) is a feasible alternative to pneumonectomy; however, the survival benefit is unclear, and preoperative selection of potential candidates for ESL remains a problem. MATIERALS AND METHODS ESL was performed on selected candidates with double sleeve lobectomy for more than 1 lobe (eg, left upper lobe and S6 segment resection). Three-dimensional (3-D) reconstruction was routinely validated. Patients were candidates for ESL if the predicted distal stump length was > 6 mm and the pulmonary vein of the remaining segments was not invaded. RESULTS Of the 1809 patients with centrally located lung cancer for surgical resection, 86 patients with tumors invading more than 1 lobe were enrolled in the study. After evaluation by 3-D reconstruction, 22 (95.7%) of 23 selected candidates underwent ESL, and 63 patients were deemed unsuitable for ESL and underwent pneumonectomy (43 cases) or thoracic exploration (20 cases). Surgical outcomes between the ESL and pneumonectomy groups were similar in terms of complications, blood loss and surgical duration, but the 6-minute walking distance was significantly improved in the ESL group (371 ± 111 m vs. 191 ± 55 m, respectively; P < .001). The mean forced expiratory volume in 1 second was 1.6 ± 0.3 L at the 1-year follow up examination in the ESL group. In the survival analysis, no difference was observed between the ESL and pneumonectomy groups in terms of 3-year overall survival (85% vs. 89%, respectively; P = .626) and 3-year disease-free survival (75% vs. 76%, respectively; P = .625). CONCLUSIONS ESL is a feasible and superior surgical procedure in terms of its short-term and long-term outcomes, and we suggest 3-D reconstruction to identify candidates for ESL.

Abstract
OBJECTIVE To uncover the function of LINC00461 in regulating cellular behaviors of gastric cancer (GC) via targeting LSD1. PATIENTS AND METHODS LINC00461 level in GC tissues with different tumor node metastasis (TNM) staging and lymphatic metastasis statues was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). In vitro influences of LINC00461 on proliferative and apoptotic rates were evaluated in AGS and SGC-7901 cells. The interaction between LINC00461 and LSD1 was explored by RNA immunoprecipitation (RIP) assay and qRT-PCR. Finally, the potential role of LSD1 in the proliferative ability of GC cells mediated by LINC00461 was assessed. RESULTS LINC00461 level was higher in GC tissues relative to matched control ones. It was positively correlated to TNM staging and lymphatic metastasis of GC. Knockdown of LINC00461 markedly attenuated viability and the proliferative ability of AGS and SGC-7901 cells, but induced apoptosis. RIP assay demonstrated the interaction between LINC00461 and LSD1. Moreover, LSD1 could reverse the regulatory effect of LINC00461 on the proliferative ability of GC cells. CONCLUSIONS LINC00461 is upregulated in GC, which is positively related to TNM staging and lymphatic metastasis. LINC00461 mediates proliferation and apoptosis of GC cells, thereafter aggravating the progression of GC.

Abstract
OBJECTIVE To uncover the biological effect of long non-coding RNA (lncRNA) PAPAS on the progression of gastric cancer (GC) by mediating microRNA-188-5p (miRNA-188-5p) level. PATIENTS AND METHODS The relative level of PAPAS was determined in GC tissues and cell lines by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The Kaplan-Meier method was introduced to assess the prognostic potential of PAPAS in the overall survival of GC patients. Regulatory effects of PAPAS on proliferative, migratory, and invasive abilities of HGC-27 and AGS cells were detected by cell counting kit-8 (CCK-8), transwell, and wound closure assay, respectively. Subsequently, the binding relation between PAPAS and miRNA-188-5p was verified by the Dual-luciferase reporter gene assay. Correlation between expression levels of PAPAS and miRNA-188-5p in GC tissues was explored. Finally, rescue experiments were conducted to uncover the role of PAPAS/miRNA-188-5p axis in the progression of GC. RESULTS PAPAS was upregulated in GC tissues and cell lines compared to controls. GC patients expressing a high level of PAPAS suffered worse prognosis relative to those with low level. The silence of PAPAS remarkably attenuated proliferative, migratory, and invasive abilities of HGC-27 cells. Overexpression of PAPAS in AGS cells obtained the opposite trends. MiRNA-188-5p was the direct target of PAPAS, which was negatively regulated by PAPAS. MiRNA-188-5p was able to reverse the regulatory effects of PA-PAS on proliferative, migratory, and invasive abilities of GC cells. CONCLUSIONS LncRNA PAPAS is upregulated in GC and closely related to lymphatic metastasis, distant metastasis, and poor prognosis of GC patients. PAPAS aggravate the malignant progression of GC by negatively regulating the miRNA-188-5p level.

Abstract
Background This study aimed to report the experience of diagnosis and treatment of one rare case of mediastinal lymph node tuberculous abscess (MLNTA) using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Case presentation An 18-year-old female patient was hospitalized in the Affiliated Hospital of Xuzhou Medical University in November 2017, due to intermittent left chest pain. She was suspected of infecting tuberculosis (TB) and thus received anti-TB treatment. Since April 1, 2018, she began to exhibit symptoms of chest distress. The patient was then admitted to Shanghai Pulmonary Hospital and continued receiving systemic anti-TB treatment during the whole course. On April 11, 2018, she received EBUS-TBNA to puncture pus and inject isoniazid. Simultaneously, the pus was sent for cytopathological and bacteriological examination, both supporting the diagnosis of TB in the patient. On April 24 and May 10, she received two times of EBUS-TBNA treatment. The symptoms of chest distress were relieved, but granulomatous neoplasm occurred at the EBUS-TBNA site on the trachea wall. The patient then received local clamp removal and cryotherapy on May 29 and Jul 19, respectively. Chest computed tomography (CT) reexamination on September 28 revealed that the MLNTA lesion had been completely absorbed, and electronic bronchoscopic reexamination on September 30 demonstrated that the granulomatous neoplasm on the trachea wall was entirely invisible. Conclusions Using EBUS-TBNA to puncture and aspirate pus and inject drugs can be effectively used to diagnose and treat MLNTA, which provides a new, less invasive, safe and reliable method for diagnosis and treatment of MLNTA.

Abstract
Mycoplasma pneumoniae is an obligate pathogen that causes pneumonia, tracheobronchitis, pharyngitis and asthma in humans. It is well recognized that membrane lipoproteins are immunostimulants exerting as lipopolysaccharides (LPS) and play a crucial role in the pathogenesis of inflammatory responses upon M. pneumoniae infection. Here, we report that the M. pneumoniae-derived lipids are another proinflammatory agents. Using an antibody-neutralizing assay, RNA interference or specific inhibitors, we found that Toll-like receptor 4 (TLR-4) is essential for M. pneumoniae lipid-induced tumour necrosis factor (TNF)-α and interleukin (IL)-1β production. We also demonstrate that NLR family pyrin domain containing 3 inflammasome (NLRP3) inflammasome, autophagy and nuclear factor kappa B (NF-κB)-dependent pathways are critical for the secretion of proinflammatory cytokines, while inhibition of TLR-4 significantly abrogates these events. Further characterization revealed that autophagy-mediated inflammatory responses involved the activation of NF-κB. In addition, the activation of NF-κB promoted lipid-induced autophagosome formation, as revealed by assays using pharmacological inhibitors, 3-methyladenine (3-MA) and Bay 11-7082, or silencing of atg5 and beclin-1. These findings suggest that, unlike the response to lipoprotein stimulation, the inflammation in response to M. pneumoniae lipids is mediated by the TLR-4 pathway, which subsequently initiates the activation of NLRP3 inflammasome and formation of a positive feedback loop between autophagy and NF-κB signalling cascade, ultimately promoting TNF-α and Il-1β production in macrophages.

Abstract
OBJECTIVES Immune checkpoint inhibitors (ICIs) have revolutionized the oncologic treatment landscape, but have been accompanied by immune-related adverse events (irAEs). ICI-related pneumonitis (ICI-pneumonitis) is a potentially fatal irAE. However, the risk factors associated with ICI-pneumonitis remain unclear. There is an urgent need to identify risk factors for ICI-pneumonitis using reliable and accessible parameters. Here, we aimed to identify baseline peripheral-blood biomarkers correlated with ICI-pneumonitis and clinical outcomes in patients with advanced non-small cell lung cancer (NSCLC) who were treated with ICIs. MATERIALS AND METHODS We conducted a retrospective analysis of eligible patients with advanced NSCLC who were treated with ICIs at our center. Receiver operating characteristic (ROC) curve was used to determine the optimal cutoff value for analyzing risk of ICI-pneumonitis. Multivariate logistic analysis was performed to identify risk factors of ICI-pneumonitis. Clinical characteristics and treatment outcomes were collected and compared according to the optimal cutoff value. RESULTS A total of 300 patients were included, in which 54 patients (18 %) experienced ICI-pneumonitis. Patients with ICI-pneumonitis had a high level of baseline peripheral-blood absolute eosinophil count (AEC) than those without ICI-pneumonitis (P = 0.013). The optimal threshold of baseline peripheral-blood AEC to predict ICI-pneumonitis was 0.125 × 109 cells/L. The incidence of ICI-pneumonitis was higher in the high-AEC group (AEC ≥ 0.125 × 109 cells/L; 27.7 %) than in the low-AEC group (AEC < 0.125 × 109 cells/L; 9.8 %, P < 0.001). Moreover, patients with high AEC (compared with those with low AEC) had a higher objective response rate (ORR) (40.9 % versus 28.8 %, P = 0.029) and longer median progression-free survival (PFS) (8.93 months versus 5.87 months, P = 0.038). CONCLUSIONS Among patients treated with ICIs, a baseline feature of high AEC (≥0.125 × 109 cells/L) was associated with an increasing risk of ICI-pneumonitis, and with a better clinical outcome.

Abstract
BACKGROUND Prolonged hospitalization and immobility of critical care patients elevates the risk of long-term physical and cognitive impairments. However, the therapeutic effects of early mobilization have been difficult to interpret due to variations in study populations, interventions, and outcome measures. This systematic review and meta-analysis aims to assess the effects of early mobilization therapy for non-emergency cardiac surgery patients in the intensive care unit (ICU). METHODS The following databases will be used to search for relevant keywords: PubMed, Embase, CINAHL, PEDro, and the Cochrane Library from inception to September 2018 by 2 researchers independently. Randomized controlled trials (RCTs), will be included if patients are adults (≥18 years) admitted to any ICU for cardiac surgery due to cardiovascular disease and who are treated with experimental physiotherapy initiated in the ICU (pre, post, or perioperative). The Review Manager 5.3 will be used for meta-analysis and the evidence level will be assessed by using the method for Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Continuous outcomes will be presented as the weighted mean difference (WMD) or standardized mean difference (SMD) with 95% confidence interval (CI), while dichotomous data will be expressed as relative risk (RR) with 95% CI. If the included studies have existing heterogeneity (P < 0.1), a random-effects model will be used. Otherwise, we will calculate using a fixed effects model. RESULTS This review will evaluate the effects of early mobilization on length of ICU and hospital stay, physical function and adverse events in patients with cardiac surgery patients in the ICU. CONCLUSION This systematic review will comprehensively provide conclusive evidence of the therapeutic effect of early mobilization on cardiac surgery patients in the ICU.PROSPERO Research registration identifying number: CRD42019135338.

Abstract
Muscle atrophy is a physiological response to disuse and malnutrition, but hibernating bears are largely resistant to this phenomenon. Unlike other mammals, they efficiently reabsorb amino acids from urine, periodically activate muscle contraction, and their adipocytes differentially responds to insulin. The contribution of myocytes to the reduced atrophy remains largely unknown. Here we show how metabolism and atrophy signaling are regulated in skeletal muscle of hibernating grizzly bear. Metabolic modeling of proteomic changes suggests an autonomous increase of non-essential amino acids (NEAA) in muscle and treatment of differentiated myoblasts with NEAA is sufficient to induce hypertrophy. Our comparison of gene expression in hibernation versus muscle atrophy identified several genes differentially regulated during hibernation, including Pdk4 and Serpinf1. Their trophic effects extend to myoblasts from non-hibernating species (including C. elegans), as documented by a knockdown approach. Together, these changes reflect evolutionary favored adaptations that, once translated to the clinics, could help improve atrophy treatment.

Abstract
Stroke is uncommon among young adults. However, the incidence of stroke among young women increases with pregnancy during peripartum and postpartum periods. The relative risk of suffering from haemorrhagic stroke was three times higher than ischemic stroke during these periods when compared with antenatal period. Neuroimaging should be prioritized in order to establish diagnosis and to facilitate treatment in a patient with suspected acute stroke. Prophylaxic anticoagulants should be used in high risk patients. Treatments of acute stroke in pregnant women include anti-platelet and thrombolytic agents. Further studies should be carried as there is lack of high level of evidences to formulate clear guideline for the management of stroke during pregnancy.

Abstract
Experimental and computational simulation methods are used to investigate the adsorption behavior of the surfactant nonylphenol ethoxylate (NPEO10), which contains 10 ethylene oxide groups, on the lignite surface. The adsorption of NPEO10 on lignite follow a Langmuir-type isotherm. The thermodynamic parameters of the adsorption process show that the whole process is spontaneous. X-ray photoelectron spectroscopic (XPS) analysis indicates that a significant fraction of the oxygen-containing functional groups on the lignitic surface were covered by NPEO10. Molecular dynamics (MD) simulations show that the NPEO10 molecules were found to adsorb at the water-coal interface. Moreover, polar interactions are the main effect in the adsorption process. The density distributions of coal, NPEO10, and water molecules along the Z axis show that the remaining hydrophobic portions of the surfactant extend into the solution, creating a more hydrophobic coal surface that repels water molecules. The negative interaction energy calculated from the density profiles of the head and tail groups along the three spatial directions between the surfactant and the lignitic surface suggest that the adsorption process is spontaneous. The self-diffusion coefficients show that the presence of NPEO10 causes higher water mobility by improving the hydrophobicity of lignite.

Abstract
Background This study aimed to compare the efficacy of closed-chest drainage with rib resection closed drainage of chronic tuberculous empyema. Methods This retrospective study reviewed 86 patients with tuberculous empyema in Shanghai Pulmonary Hospital from August 2010 to November 2015. Among these included patients, 22 patients received closed-chest drainage, and 64 patients received rib resection closed drainage. Results The results showed that after intercostal chest closed drain treatment, 2 (9.09%) patients were recovery, 13 (59.09%) patients had significantly curative effect, 6 (27.27%) patients had partly curative effect, and 1 (4.55%) patient had negative effect. After treatment of rib resection closed drainage, 9 (14.06%) patients were successfully recovery, 31 (48.44%) patients had significantly curative effect, 19 (29.69%) patients had partly curative effect, and 5 (7.81%) patients had negative effect. There was no significant difference in the curative effect (P>0.05), while the average catheterization time of rib resection closed drainage (130.05±13.12 days) was significant longer than that (126.14±36.84 days) in course of intercostal chest closed drain (P<0.05). Conclusions This study had demonstrated that closed-chest drainage was an effective procedure for treating empyema in young patients. It was less invasive than rib resection closed drainage and was associated with less severe pain. We advocated closed-chest drainage for the majority of young patients with empyema, except for those with other diseases.

Abstract
To investigate computed tomography (CT) characteristics of benign and malignant solitary fibrous tumors of the pleura (SFTPs).Preoperative CTs for 60 SFTP cases (49 benign and 11 malignant) with subsequently confirmed diagnoses were retrospectively analyzed.Tumor morphologies included mounded or mushroom umbrella-shape (19 cases, 31.7%), quasi-circular or oval-shape (30 cases, 50%), and growth resembling a casting mould (12 cases, 20%). Maximum tumor diameters were 1.1 to 18.9 cm (average: 6.4 ± 4.8 cm). Fifty-seven cases had clear boundaries, and 3 had partially coarse boundaries. Twenty-seven cases showed homogeneous density; 33, "geographic"-patterned inhomogeneous density; 6, calcifications; 12, intratumor blood vessels; and 3, thick nourishing peritumoral blood vessels. Pleural thickening (regular and irregular) was found adjacent to tumors in 4, compression of adjacent ribs with absorption and cortical sclerosis in 2, and location adjacent to ribs with bony destruction in 1. Four cases had a small amount of lung tissue enfolded along the boundary, 2 had multiple peritumoral pulmonary bullae, and 9 had small ipsilateral pleural effusions. Compared with benign and malignant SFTPs were larger (P < .001), had inhomogeneous density, and were more commonly associated with intratumor blood vessels and pleural effusions (P < .01).CT revealed characteristic patterns in SFTPs, including casting mould-like growth, rich blood supply, and "geographic"-patterned enhancement. In addition, larger tumor size, inhomogeneous intensities, abundant intratumor blood vessels, and pleural effusions were more common with malignancy. Lastly, multislice CT angiography can reveal feeding arteries and help guide surgical management.

Abstract
Background During ischemic stroke (IS), adenosine 5′-triphosphate (ATP) is released from damaged nerve cells of the infract core region to the extracellular space, invoking peri-infarct glial cellular P2 purinoceptors singling, and causing pro-inflammatory cytokine secretion, which is likely to initiate or aggravate motor and cognitive impairment. It has been proved that electroacupuncture (EA) is an effective and safe strategy used in anti-inflammation. However, EA for the role of purine receptors in the central nervous system has not yet been reported. Methods Ischemia-reperfusion injured rat model was induced by middle cerebral artery occlusion and reperfusion (MCAO/R). EA treatment at the DU 20 and DU 24 acupoints treatment were conducted to rats from the 12 h after MCAO/R injury for consecutive 7 days. The neurological outcomes, infarction volumes and the level of astroglial and microglial/macrophage hyperplasia, inflammatory cytokine and P2X7R and P2Y1R expression in the peri-infarct hippocampal CA1and sensorimotor cortex were investigated after IS to evaluate the MCAO/R model and therapeutic mechanism of EA treatment. Results EA effectively reduced the level of pro-inflammatory cytokine interleukin-1β (IL-1β) as evidenced by reduction in astroglial and microglial/macrophage hyperplasia and the levels of P2X7R and ED1, P2X7R and GFAP, P2Y1R and ED1, P2Y1R and GFAP co-expression in peri-infarct hippocampal CA1 and sensorimotor cortex compared with that of MCAO/R model and Non-EA treatment, accompanied by the improved neurological deficit and the motor and memory impairment outcomes. Therefore, our data support the hypothesis that EA could exert its anti-inflammatory effect via inhibiting the astroglial and microglial/macrophage P2 purinoceptors (P2X7R and P2Y1R)-mediated neuroinflammation after MCAO/R injury. Conclusion Astroglial and microglial/macrophage P2 purinoceptors-mediated neuroinflammation and hyperplasia in peri-infarct hippocampal CA1 and sensorimotor cortex were attenuated by EA treatment after ischemic stroke accompanied by the improved motor and memory behavior performance.

Abstract
Abstract
Analysis of circulating tumor DNA (ctDNA) is emerging as a powerful tool for guiding targeted therapy and monitoring tumor evolution in patients with non-small cell lung cancer (NSCLC), particularly when fresh tissue biopsy is not available. This study compared the ability of four leading technology platforms to detect epidermal growth factor receptor (EGFR) mutations (L858R, exon 19 deletion, T790M and G719X) in ctDNA from NSCLC patients. The platforms included two amplification refractory mutation systems (cobas-ARMS and ADx-ARMS), a droplet digital polymerase chain reaction platform (ddPCR) and a next-generation sequencing platform (Firefly NGS). Fifteen EGFR mutations across twenty NSCLC patients were identified. We observed superior sensitivity and specificity of cobas-ARMS, ddPCR and Firefly NGS platforms, while ADx-ARMS was only suitable for the qualitative detection of EGFR mutations with allele frequency higher than 1% in plasma samples. We observed high concordance between the plasma and tissue EGFR mutational profiles for three driver mutations that are known targets of the first generation EGFR-TKI therapy (L858R, E19-dels, and G719X). Discrepancies between plasma and tissue EGFR mutational profiling could be attributed to spatial and temporal tumor heterogeneity. This pilot study illustrates the promise of ctDNA analysis in the context of treatment evaluation and drug resistance detection, and results will be validated in follow-up studies.

Abstract
We present direct detection constraints on the absorption of hidden-photon dark matter with particle masses in the range 1.2-30 eV c^{-2} with the DAMIC experiment at SNOLAB. Under the assumption that the local dark matter is entirely constituted of hidden photons, the sensitivity to the kinetic mixing parameter κ is competitive with constraints from solar emission, reaching a minimum value of 2.2×10^{-14} at 17 eV c^{-2}. These results are the most stringent direct detection constraints on hidden-photon dark matter in the galactic halo with masses 3-12 eV c^{-2} and the first demonstration of direct experimental sensitivity to ionization signals <12 eV from dark matter interactions.

This study illustrates the challenges associated with selection of a technology platform for EGFR ctDNA analysis in the context of treatment evaluation and drug resistance detection.

Abstract
A circular-route scanning method called α-β circular scanning is proposed and realized using sinusoidal signals with a constant phase difference of π/2. Experiments show that the circular scanning range of α-β circular scanning is 57% greater than the rectangular scanning range of raster scanning within an effective optical field of view. Moreover, the scanning speed is improved by 7.8% over raster scanning because the whole sine signal is utilized in α-β circular scanning whereas the flyback area of the saw-tooth signal needs to be discarded in raster scanning. The maximum scanning acceleration decreases by a factor of 44, drastically decreasing the high noise, which should considerably elongate the lifetime of the galvanometers while inhibiting internal vibration. The proposed α-β circular scanning technique could be used in scanning imaging, optical tweezers and laser-beam fabrication.

Abstract
The aim of this study was to assess whether CT imaging using an ultra-high-resolution CT (UHRCT) scan with a small scan field of view (FOV) provides higher image quality and helps to reduce the follow-up period compared with a conventional high-resolution CT (CHRCT) scan. We identified patients with at least one pulmonary nodule at our hospital from July 2015 to November 2015. CHRCT and UHRCT scans were conducted in all enrolled patients. Three experienced radiologists evaluated the image quality using a 5-point score and made diagnoses. The paired images were displayed side by side in a random manner and annotations of scan information were removed. The following parameters including image quality, diagnostic confidence of radiologists, follow-up recommendations and diagnostic accuracy were assessed. A total of 52 patients (62 nodules) were included in this study. UHRCT scan provides a better image quality regarding the margin of nodules and solid internal component compared to that of CHRCT (P < 0.05). Readers have higher diagnostic confidence based on the UHRCT images than of CHRCT images (P<0.05). The follow-up recommendations were significantly different between UHRCT and CHRCT images (P<0.05). Compared with the surgical pathological findings, UHRCT had a relative higher diagnostic accuracy than CHRCT (P > 0.05). These findings suggest that the UHRCT prototype scanner provides a better image quality of subsolid nodules compared to CHRCT and contributes significantly to reduce the patients' follow-up period.

Abstract
UNLABELLED Syphilis is a multistage sexually transmitted disease that remains a serious public health concern worldwide. The coexistence of Treponema pallidum with other closely related members of spirochaeta, such as Leptospira spp. and Borrelia burgdorferi, has complicated the serodiagnosis due to cross-reactive antigens. In this study, recombinant Tp0821 protein was expressed in Escherichia coli and purified by metal affinity chromatography. Then enzyme-linked immunosorbent assays (ELISAs) based on Tp0821 for the detection of specific antibodies were established. The relative positive rates of the IgM ELISA and the IgG ELISA were found to be 91·0 and 98·3%, respectively, when screening 578 syphilis specimens. The specificities were 94·3 and 100%, respectively, when cross-checking with serum samples obtained from 30 patients with Lyme disease, five patients with leptospirosis, and 52 uninfected controls. In addition, relative positive rates and specificities of Tp0821 for human sera were all 100% in Western blotting. When compared to the syphilis diagnostic tests commonly used in clinical settings, we found that the results of Tp0821-based ELISAs correlated well with the results of the treponemal tests, specifically the T. pallidum particle agglutination (TP-PA) test and the chemiluminescent immunoassay (CIA). Thus, these findings identify Tp0821 as a novel serodiagnostic candidate for syphilis. SIGNIFICANCE AND IMPACT OF THE STUDY In this study, we expressed and purified the Treponema pallidum protein Tp0821 and developed Tp0821-based enzyme-linked immunosorbent assays (ELISAs) for the detection of specific antibodies. The serodiagnostic performance of the recombinant protein was then evaluated. When compared to the results of syphilis diagnostic tests commonly used in clinical settings, we found that the reactivities of syphilitic sera with the recombinant antigen correlated well with the results of the treponemal tests, specifically the T. pallidum particle agglutination (TP-PA) test and the chemiluminescent immunoassay (CIA). Thus, the recombinant protein shows promise as a new diagnostic antigen in the ELISAs.

Abstract
BACKGROUND AND PURPOSE In the SELECT study, treatment with daclizumab high-yield process (DAC HYP) versus placebo reduced the frequency of gadolinium-enhancing (Gd(+) ) lesions in patients with relapsing-remitting multiple sclerosis (RRMS). The objective of this post hoc analysis of SELECT was to evaluate the effect of DAC HYP on the evolution of new Gd(+) lesions to T1 hypointense lesions (T1 black holes). METHODS SELECT was a randomized double-blind study of subcutaneous DAC HYP 150 or 300 mg or placebo every 4 weeks. Magnetic resonance imaging (MRI) scans were performed at baseline and weeks 24, 36 and 52 in all patients and monthly between weeks 4 and 20 in a subset of patients. MRI scans were evaluated for new Gd(+) lesions that evolved to T1 black holes at week 52. Data for the DAC HYP groups were pooled for analysis. RESULTS Daclizumab high-yield process reduced the number of new Gd(+) lesions present at week 24 (P = 0.005) or between weeks 4 and 20 (P = 0.014) that evolved into T1 black holes at week 52 versus placebo. DAC HYP treatment also reduced the percentage of patients with Gd(+) lesions evolving to T1 black holes versus placebo. CONCLUSIONS Treatment with DAC HYP reduced the evolution of Gd(+) lesions to T1 black holes versus placebo, suggesting that inflammatory lesions that evolved during DAC HYP treatment are less destructive than those evolving during placebo treatment.

Abstract
PURPOSE To investigate the characteristics of various near work related behaviors among primary students and their associations with changes in myopia related ocular biometric parameters during one-year of follow up. METHODS A school-based sample of 4,814 primary 1st to 4th grade students aged 6-10 years old were selected by cluster randomization based on probability proportion to size in 2013. At baseline, students together with their parents filled in a self-administered questionnaire on 9 aspects of near work related behaviors and some important covariants of myopia. A comprehensive set of eye examinations including axial length (AL) and cycloplegic refraction was conducted both at baseline and one year later. RESULTS With the grade level increase, students did increasingly better at finding various ways to have an eye break, but they were increasingly likely to continuously do long-time near work without an eye break. Keeping a reasonable eye distance and correct hand posture for reading, writing, or watching TV became worse for the first time before grade 2, but then became better at grade 3. In contrast, selecting appropriate lighting environments or situations and keeping a balanced diet became better for the first time before grade 2, but then became worse at grade 3. At one-year follow up, the mean AL increased by 0.32 ± 0.35 mm, the ratio of AL divided by the mean corneal radius of curvature (AL/CR ratio) increased by 0.032 ± 0.054, the myopic spherical equivalent (SE) increased by -0.51 ± 0.51 diopters and the incidence of myopia was 16.0% (237/1,477). After controlling for the confounding effects of parental myopia, student's age, gender, height, daily near work time, daily outdoor activity time and all of the other near work related behaviors, keeping a reasonable distance when reading, writing and watching TV was associated with elongation of the AL [standard coefficient beta = -0.062, P = 0.004], a change in SE [beta = -0.072, P = 0.020] and incident myopia [adjusted odds ratio (aOR) = 0.90, 95% confidence interval (CI): 0.84-0.96]. Selecting an environment with adequate light for visual comfort to read and write was related to elongation of the AL [beta = -0.039, P = 0.034] and increase of AL/CR ratio [beta = -0.030, P = 0.048]. Also, not continuing to do near work for more than 30-40 minutes without an eye break was related to increase of the AL/CR ratio [beta = -0.028, P = 0.044] and a change in SE [beta = -0.064, P = 0.023]. CONCLUSION Various near work related behaviors changed according to grade level in primary school students. Independent of hereditary factors, daily near work load and outdoor activity, near work related behaviors such as keeping an inappropriate eye distance for near work, selecting inadequate lighting environments, and continuing to do near work without an eye break were risk factors for myopic shifts.

Abstract
Background Bronchoscopic balloon dilatation (BBD) is a common strategy in the treatment of bronchostenosis. However, the longer dilating time in each inflation cycle (approximately 3–5 min) without mechanical ventilation is not possible for the treatment of tracheal stenosis. Case presentation In this study, we reported our experience of BBD with shorter dilating time (10 s or 1 min) and intermittent ventilation for the repair of tuberculous-associated tracheal stenosis in two cases of our hospital. After the surgeries, the physical examinations and pulmonary function were tested. In case 1, the cough and dyspnea syndromes subsided, wheeze and strid or in lungs were remarkably reduced, tracheal lumen was considerably expanded and pulmonary function was improved following the treatment. For the case 2, her chest tightness, shortness of breath symptoms were alleviated after the treatment. The middle and lower trachea stenosis was dilated and patent, but the right main bronchus stenosis was slightly improved. No restenosis occurred in the two patients in 1 year outpatient follow-up. Conclusions These findings suggest that our modification in BBD is safe and effective for treating this patient with tracheal stenosis caused by tuberculosis, but the longer-term effect of the surgery in a large number of patients with longer follow-up remains to be seen.

Abstract
Chalcone isomerase (CHI) is a key enzyme involved in anthocyanin metabolism. Previous research on CHI has mainly focused on cDNA cloning and gene expression. In the current study, the 1425-bp potato CHI promoter (PCP) was isolated from four potato cultivars (Heijingang, Zhongshu 7, Désirée, and Favorita) using PCR and DNA sequencing. The PCP contained many cis-regulatory elements (CREs) related to anthocyanin metabolism, tissue specificity, light response, stress, and hormone induction. Of the PCP CREs identified, 19 were common to those found in the higher plants examined, based on plant CRE databases. Multiple sequence alignment showed six single nucleotide variation sites in PCP among the potato cultivars examined, resulting in changes in the number of CREs connected with tissue specificity, anthocyanin metabolism, and light response. The 665-bp PCP fragments from Favorita and 1425-bp PCP fragments from Heijingang were used to construct plant expression vectors, which may be a useful tool for biological engineering. A transient expression assay demonstrated that the two PCP fragments from Heijingang could direct the expression of a green fluorescent protein gene in onion epidermis and a β-glucuronidase gene in all potato tuber tissues with different colors, suggesting that the single nucleotide variation in the PCP did not affect its activity, and that silencing of the CHI gene in Favorita may be attributed to other regulatory factors.
