Abstract
A 38-year-old female presented with a 10-month history of right shoulder pain with impingement symptoms. She was diagnosed on magnetic resonance (MR) imaging to have supraspinatus tendon tear and degenerative changes contributing to subacromial impingement. She also had lipoma arborescens of the subacromial-subdeltoid bursa, an uncommon condition in a particularly rare location. Lipoma arborescens is a benign intra-articular condition characterized by lipomatous proliferation of synovium with replacement of subsynovial tissue by mature adipocytes. It is typically a monoarticular process affecting the knee. Due to the presence of pathognomonic fat, diagnosis is usually straightforward with MR as the preferred imaging modality.

Abstract
Electrostatic accelerometers have extremely high sensitivity and are ideal scientific instruments for measuring very weak acceleration. In particular, a single-sensitive-axis electrostatic accelerometer can be used for testing the equivalence principle in space. Sensitive-axis capacitances formed by axial electrodes and a cylindrical proof mass vary with the axial motion of the mass and are also affected by radial motion, which results in cross-axis coupling disturbances. A quantitative model is built to analyze the cross-axis coupling effect on the sensitive axis from the radial suspension loop, including a nonlinear model for large radial motion and a linear model for small radial motion. Frequency response simulation shows that the cross-axis coupling effect for a small signal case arises mostly in the high-frequency range. Experiments are carried out with a ground-based electrostatic accelerometer made of a single, non-rotating test cylinder, and in this case, the experimental results are utilized to verify the mathematical model. Cross-axis coupling for small signal perturbations is virtually removed if the equilibrium position of the proof mass is calibrated to the null position of the sensor cage. In addition, data post-processing can further attenuate the cross-axis coupling disturbances when dealing with large radial motion. The cross-axis coupling disturbances on both the position and the acceleration measurement signals in the sensitive axis are mostly removed in ground-based experiments. The proposed model and compensation can be extended to space equivalence principle instruments and other electrostatic accelerometers with a cylindrical proof mass.

Abstract
AIMS C-reactive protein (CRP) and matrix metalloproteinase (MMP)-9 are involved in the inflammation of atherosclerosis lesions. Genistein (Gen) has been demonstrated to exert beneficial effect on the cardiovascular system. However, it remains unclear whether Gen produces anti-inflammatory effect in vascular smooth muscle cells (VSMCs). Therefore, we investigated the effects of Gen on CRP and MMP-9 expressions induced by angiotensin (Ang) II in VSMCs and the related molecular mechanism. MAIN METHODS Rat VSMCs were cultured, and Ang II was used as a stimulant for CRP and MMP-9 expressions. CRP level was measured by ELISA. The mRNA and protein expressions of related indexes were identified by reverse transcription-polymerase chain reaction and western blot, respectively. KEY FINDINGS Gen inhibited Ang II-stimulated CRP and MMP-9 mRNA and protein expressions in concentration- and time-dependent manners. Additionally, Gen ameliorated Ang II-induced p-ERK1/2, p-p38 and NF-κB expressions, antagonized Ang II-downregulated peroxisome proliferation-activated receptor (PPAR) γ and estrogen receptor (ER) β expressions. After treating the VSMCs with GW9662 or ICI182780 in Gen treated groups, inhibitory effect of Gen on CRP and MMP-9 expressions were antagonized in Ang II-stimulated VSMCs. The treatment of VSMCs with ICI182780 abolished downregulations of p-p38/p-ERK1/2, and antagonized upregulation of PPARγ by Gen in Ang II-stimulated VSMCs. Moreover, the inhibitory effect of Gen on Ang II-stimulated NF-κB expression was abolished after preincubation of VSMCs with GW9662 in Gen treated groups. SIGNIFICANCE Gen exerts anti-inflammatory property via the ER-p38/ERK1/2-PPARγ-NF-κB-CRP/MMP-9 signal pathway in Ang II-stimulated VSMCs.

Abstract
Objective: To explore the effect of metformin on murine model of bleomycin (BLM)-induced lung injury and fibrosis. Methods: A total of 30 mice were divided into 3 groups: control, BLM, and BLM with metformin, in accordance with the random number table and each group had 10 mice. To induce the pulmonary fibrosis model, a concentration of 2 mg/ml bleomycin was intratracheally administered in the BLM group and BLM with metformin group with a volume of 1.75 μl/g, while the control group accepted saline with the same volume. Metformin (200 mg/kg) was given to the mice orally once a day from the day before intratracheal instillation of bleomycin to day 14. The daily survival condition of mice was recorded during 14 days. At day 14, HE-staining was used to assess the severity of fibrosis according to the method proposed by Ashcroft. Total lung collagen content was determined by hydroxyproline assay and Masson's trichrome staining. To examine the expression of fibronectin we used the method of immunohistochemistry staining. The changes of Transforming Growth Factor beta 1 (TGF-β(1)) in plasm, bronchoalveolar lavage fluid (BALF) and lung were measured by ELISA. Results: The survival rates of control group, BLM group and BLM with metformin group at day 14 were 10/10, 4/10 and 7/10 respectively. According to the method proposed by Ashcroft the score of metformin treated mice was significantly lower than that of the bleomycin model mice[(3.82±0.58) vs (7.79±0.06), (P<0.05)]. The hydroxyproline level in lung tissue were markedly attenuated in metformin treated mice compared with bleomycin model mice [(0.40±0.05) vs (0.73±0.10) μg/mg, (P<0.05)]. The level of TGF-β(1) in plasma, BALF and lung tissue were also decreased in mice treated with metformin compared with bleomycin model mice [(2.32±0.68) vs (4.59±0.45) ng/ml, (0.81±0.09) vs (1.40±0.06) ng/ml, (17.12±0.83) vs (21.25±0.69) ng/mg, all P<0.05]. Conclusion: Metformin can reduce the severity of pulmonary fibrosis in mice induced by bleomycin.

Abstract
Computed Tomography (CT) is a powerful method for non-destructive testing (NDT) and metrology awakes with expanding application fields. To improve the spatial resolution of high energy CT, a micro-spot gamma-ray source based on bremsstrahlung from a laser wakefield accelerator was developed. A high energy CT using the source was performed, which shows that the resolution of reconstruction can reach 100 μm at 10% contrast. Our proof-of-principle demonstration indicates that laser driven micro-spot gamma-ray sources provide a prospective way to increase the spatial resolution and toward to high energy micro CT. Due to the advantage in spatial resolution, laser based high energy CT represents a large potential for many NDT applications.

Abstract
Objective:To evaluate the clinical manifestation, therapy and prognosis of neuroendocrine carcinoma of the larynx. Method:Twenty-six cases with neuroendocrine carcinoma of the larynx were analyzed retrospectively. Four pathological types were found in our series: typical carcinoid (1/26), atypical carcinoid (15/26), small cell carcinoma, neuroendocrine type (9/26) and combined small cell carcinoma, neuroendocrine type (1/26). In this series, 12 cases were received total laryngectomy, 2 cases supracricoid partial laryngectomy-cricohyoidopexy (SCPL-CHP), 4 cases horizontal partial laryngectomy, 5 cases vertical partial laryngectomy, 1 case transoral CO₂ laser microsurgery, and 2 cases radiotherapy and/or chemotherapy. Result:Three-year and five-year overall survival rates were 76.9% and 69.2% respectively. Conclusion:The neuroendocrine carcinoma of the larynx was rare, which was more common in the supraglottis. Atypical carcinoid was the most common pathological type. Compared to SCC, the clinical feature of neuroendocrine carcinoma of the larynx was non-specific. The clinical behavior, treatment,and prognosis were correlative to the tumor pathological.The diagnosis depended on comprehensive immunohistochemistry examination.

Abstract
Purpose Prostate cancer (PCa) causes a common male urinary system malignant tumour, and the molecular mechanisms of PCa are related to the abnormal regulation of various signalling pathways. An increasing number of studies have suggested that mRNAs, miRNAs, lncRNAs, and TFs could play important roles in various biological processes that are associated with cancer pathogenesis. This study aims to reveal functional genes and investigate the underlying molecular mechanisms of PCa with bioinformatics. Methods Original gene expression profiles were obtained from the GSE64318 and GSE46602 datasets in the Gene Expression Omnibus (GEO). We conducted differential screens of the expression of genes (DEGs) between two groups using the online tool GEO2R based on the R software limma package. Interactions between differentially expressed miRNAs, mRNAs and lncRNAs were predicted and merged with the target genes. Co-expression of miRNAs, lncRNAs and mRNAs was selected to construct mRNA-miRNA-lncRNA interaction networks. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed for the DEGs. Protein-protein interaction (PPI) networks were constructed, and transcription factors were annotated. Expression of hub genes in the TCGA datasets was verified to improve the reliability of our analysis. Results The results demonstrate that 60 miRNAs, 1578 mRNAs and 61 lncRNAs were differentially expressed in PCa. The mRNA-miRNA-lncRNA networks were composed of 5 miRNA nodes, 13 lncRNA nodes, and 45 mRNA nodes. The DEGs were mainly enriched in the nuclei and cytoplasm and were involved in the regulation of transcription, related to sequence-specific DNA binding, and participated in the regulation of the PI3K-Akt signalling pathway. These pathways are related to cancer and focal adhesion signalling pathways. Furthermore, we found that 5 miRNAs, 6 lncRNAs, 6 mRNAs and 2 TFs play important regulatory roles in the interaction network. The expression levels of EGFR, VEGFA, PIK3R1, DLG4, TGFBR1 and KIT were significantly different between PCa and normal prostate tissue. Conclusion Based on the current study, large-scale effects of interrelated mRNAs, miRNAs, lncRNAs, and TFs established a new prostate cancer network. In addition, we conducted functional module analysis within the network. In conclusion, this study provides new insight for exploration of the molecular mechanisms of PCa and valuable clues for further research into the process of tumourigenesis and its development in PCa.

Abstract
AbstractObjective:To study the effect of obstructive sleep apnea(OSA) on the life quality of children. Method: Forty-four OSA children diagnosed with overnight polysomnography were selected as the research object, 35 cases of pediatric no snoring healthy children were as control. The inventory of subjective life quality and children's self-rating anxiety scale were used to assess children' s life quality. Result: Depending on the data of the inventory of subjective life quality questionnaire, each level and dimension of children' s life quality satisfaction scores in OSA group were significantly lower than that in healthy controls(P<0.05), especially in the cognitive component of school life(3.78±1.73) and the affective component of depression experience(3.70±2.18). The score of anxiety disorder in OSA group (21.39±10.49) was higher than that in healthy control group(14.21±9.69)( P<0.05). The rate of anxiety disorder in OSA group was higher than that in healthy control group(P<0.05). Conclusion:Children in OSA group had higher incidence of unsatisfactory life quality in all levels and dimensions. OSA group children dissatisfied with the life quality in each level, each dimensions have significant statistical difference, especially in the cognitive component of school life and affective components of depression experience. The OSA group had higher anxiety disorders than healthy ones.

Abstract
BACKGROUND Several studies have shown that B7-H4 expression is significantly increased in ovarian cancer. However, the role of B7-H4 expression in ovarian cancer remains unclear, and some studies reporting conflicting results. A systematic review of the literature and meta-analysis were conducted to assess the clinicopathologic characteristics and prognostic significance of B7-H4 in ovarian cancer. METHODS Eligible studies were searched in the PubMed, MEDLINE, Cochrane Library, and the China National Knowledge Infrastructure databases. The included studies assessed the relationship between B7-H4 expression and clinicopathologic features or prognosis in patients with ovarian cancer through September 2017. A total of 1045 patients in 10 studies were included in the meta-analysis. Stata software version 12.0 was used to analyze the data. We used an odds ratio (OR) or hazard ratio (HR) with a 95% confidence interval (CI) to assess the risk or hazard association. RESULTS B7-H4 expression in ovarian cancer patients was significantly increased (OR: 4.20, 95% CI: 2.85-6.18, Z = 6.91, P < .05), and heterogeneity was low between studies (I = 8.2%, P = .366). With respect to the clinicopathologic features, no relation was detected between B7-H4 expression and International Federation of Gynaecology and Obstetricsstages stages (OR: 0.81, 95% CI: 0.64-1.03, Z = 1.70, P = .09), pathologic grade (OR: 0.91, 95% CI: 0.72-1.16, Z = 0.76, P = .45), tumor metastasis (OR: 1.25, 95% CI: 0.90-1.74, Z = 1.34, P = .18), or histologic type (OR: 1.17, 95% CI: 0.85-1.60, Z = 0.96, P = .34) in ovarian cancer. Furthermore, B7-H4 expression was significantly associated with a worse progression-free survival (PFS) (HR: 1.30, 95% CI: 1.17-1.45, Z = 4.79, P < .05). CONCLUSION B7-H4 expression was related to ovarian cancer, but not to patients' clinicopathologic characteristics. High B7-H4 expression was negatively correlated with survival outcome, suggesting that B7-H4 plays an essential role in poor prognosis in ovarian cancer patients.

Abstract
The dissipation of triforine in the immature and mature fruit periods was investigated under field conditions. Residue levels of triforine in watermelon were determined by gas chromatography with an electron capture detector (GC-ECD). The decline curves of triforine residues in the watermelon corresponded with first-order kinetics. The half-lives of triforine in Dark Belle and Shiny Boy were 2.10-2.57 days and 2.31-2.67 days respectively. Meanwhile, the half-lives of triforine in the immature and mature fruit periods were 1.69-2.04 days and 2.89-3.85 days, respectively. In the terminal residue experiment, the terminal residues of triforine in the watermelon flesh and peel were below 0.01 mg/kg to 0.05 mg/kg and 0.03 mg/kg to 0.36 mg/kg, respectively. The dissipation rates of triforine varied in different cultivars of watermelon, and even in the same cultivar, the half-lives of triforine significantly varied in the different fruit periods. Although triforine is a fungicide within the suction, the terminal residues in the peel and flesh were very significant.

Abstract
The structural and electronic properties of bilayer (AA- and AB-stacked) and tri-layer (AAA-, ABA- and AAB-stacked) penta-graphene (PG) have been investigated in the framework of density functional theory. The present results demonstrate that the ground state energy in AB stacking is lower than that in AA stacking, whereas ABA stacking is found to be the most energetically favorable, followed by AAB and AAA stackings. All considered model configurations are found to be semiconducting, independent of the stacking sequence. In the presence of a perpendicular electric field, their band gaps can be significantly reduced and completely closed at a specific critical electric field strength, demonstrating a Stark effect. These findings show that few-layer PG will have tremendous opportunities to be applied in nanoscale electronic and optoelectronic devices owing to its tunable band gap.

Abstract
Phase-change memory is one of the most promising candidates for future memory technologies. However, most of the phase-change memories are based on chalcogenides, while other families of materials for this purpose remain insufficiently studied. In this work, we investigate the optical properties and microstructure of Ga16Sb84 by an in-situ ellipsometer and X-ray diffraction. Our experimental results reveal that the Ga16Sb84 films exhibit a relatively high crystallization temperature of ~250 °C, excelling in long data retention. In addition, a large optical contrast exists between the amorphous and crystalline states, which may make it suitable for use in optical discs. Molecular dynamics simulations indicate that a unique local structure order in the amorphous and crystalline phases is responsible for the optical properties observed in the experiment. The similarity found in the short-range orders of the amorphous and crystalline phases is beneficial to better understanding the fast phase transition of phase-change memory.

Abstract
INTRODUCTION There are a small number of reports in the literature describing bladder rupture during cystograms in children. We hypothesized that children undergoing cystograms may have their bladder overfilled during the test. We aimed to evaluate the current practice when performing cystograms in our institution, contrasting actual volume used to fill the bladder to the age-adjusted bladder capacity. METHODS We performed a retrospective review of all voiding cystourethrograms(VCUG) and radionuclide cystograms (RNC) performed at the Children's Hospital of Eastern Ontario from 2006-2013. Formulas used to estimate age-adjusted bladder capacity: 1) infants <1 year: Capacity (mL) = (2.5 × age [months]) + 38 (Holmdahl et al, 1996); and 2) older children >1 year: Capacity (mL) = (2 + age [years]) × 30 (Koff et al, 1983). RESULTS A total of 2411 cystograms were done (1387 VCUG; 1024 RNC) in 817 infants and 1594 children older than one year - 1113 boys and 1298 girls. Generally, bladders tended to be overfilled with 32% more volume in mL than the expected age-adjusted bladder capacity - VCUG 151 (122) mL vs 120 (97) mL (p< 0.001) and RNC 191 (97) mL vs. 151(74) mL (p<0.001). Most importantly, infants had a striking overfilling rate of 64% and 38 % more volume than their expected age-adjusted bladder capacity for VCUG and RNC, respectively (p<0.001). CONCLUSION Bladders are filled above the estimated age-adjusted capacity in mL at the following rates: 32% in the whole group and 64% in infants undergoing VCUG. It raises concern of possible bladder rupture in this age group. Furthermore, this may lead to overgrading and overdiagnosing of vesicoureteric reflux, as well as overestimation of post-void residual. Attention should be paid to filling to age-adjusted bladder capacity and allowing the child adequate time to void during performance of the cystogram.

Abstract
Objective: This cross-sectional study aimed to address the relationship between the volume of epicardial adipose tissue (EAT) with cardiovascular risk factors and coronary artery calcification(CAC) in the community residents. Methods: Individuals were recruited from the Jidong Community (Tangshan City, Northern China) which mainly comprised employees of the Jidong Co. Ltd. and their family members. From July 2013 to August 2014, 2 647 participants aged ≥40 years were included in this study. The volume of EAT and coronary artery calcification score (CAC score) were determined by a 64-slice CT. Carotid intima-media thickness (CIMT) was measured by a trained sonographer using a high-resolution B-mode topographic ultrasound system. Venous blood samples were analyzed by automated analyzers in the central laboratory. A validated questionnaire specifically designed for this study was used to collect demographic data from all participants by trained doctors. Characteristics of study cohort were compared according to quartiles of EAT volume (n=660, 663, 662, 662, repectively). Results: (1) The mean age of participants was (55.31±7.76) years and 49.94% (n=1 322) were men. The median EAT volume (interquartile) was 129.42 (95.66, 176.51)cm(3). (2) Age, BMI, waist circumference and hip circumference, systolic blood pressure, LDL-C, triglycerides, and fasting blood glucose were significantly higher, while HDL-C level was significantly lower in participants with higher EAT volume than participants with lower EAT volume (all P<0.05). Carotid intima-media thicken (CIMT) and higher CAC score were also significantly higher in participants with higher volume of EAT. Furthermore, percentage of diabetes mellitus, hypertension, hyperlipidemia increased in proportion with increasing EAT volume (P<0.05). (3) In the linear regression, significant positive relations were found for age (β=0.019 3, 95%CI 0.017-0.021, P<0.001), waist circumference (β=0.012 7, 95%CI 0.009-0.016, P<0.001), BMI (β=0.022 4, 95%CI 0.013-0.032, P<0.001), LDL-C (β=0.048 4, 95%CI 0.021-0.076, P<0.001), and HDL-C (β=-0.098 1, 95%CI-0.164--0.032, P<0.001) was inversely related to the EAT volume. (4) Logistic regression analysis indicated that EAT volume was an independent risk factor for CAC score>0 (OR=1.233, 95%CI 1.205-1.262, P<0.001) . Conclusions: Our findings indicate that EAT volume is strongly correlated to cardiovascular risk factors and coronary calcification and is an independent risk factor of increased coronary calcification in community residents.

Abstract
XPS and NEXAFS spectra of four stable C40 isomers [29( C2), 31( C s), 38( D2), and 39( D5 d)] have been investigated theoretically. We combined density functional theory and the full core hole potential method to simulate C 1s XPS and NEXAFS spectra for nonequivalent carbon atoms of four stable C40 fullerene isomers. The NEXAFS showed obvious dependence on the four C40 isomers, and XPS spectra are distinct for all four isomers, which can be employed to identify the four stable structures of C40. Furthermore, the individual components of the spectra according to different categories have been investigated, and the relationship between the spectra and the local structures of C atoms was also explored.

Abstract
Differential cross sections and photon-beam asymmetries for the γ[over →]p→π^{-}Δ^{++}(1232) reaction have been measured for 0.7<cosθ_{π}^{c.m.}<1 and E_{γ}=1.5-2.95 GeV at SPring-8/LEPS. The first-ever high statistics cross-section data are obtained in this kinematical region, and the asymmetry data for 1.5<E_{γ}(GeV)<2.8 are obtained for the first time. This reaction has a unique feature for studying the production mechanisms of a pure uu[over ¯] quark pair in the final state from the proton. Although there is no distinct peak structure in the cross sections, a non-negligible excess over the theoretical predictions is observed at E_{γ}=1.5-1.8 GeV. The asymmetries are found to be negative in most of the present kinematical regions, suggesting the dominance of π exchange in the t channel. The negative asymmetries at forward meson production angles are different from the asymmetries previously measured for the photoproduction reactions producing a dd[over ¯] or an ss[over ¯] quark pair in the final state. Advanced theoretical models introducing nucleon resonances and additional unnatural-parity exchanges are needed to reproduce the present data.

Abstract
The cervical lymph node metastasis is a risk factor for the high recurrence rate and low survival rate in patients with thyroid carcinoma (especially for age ≥45 years old), which is the most common head and neck carcinoma. The neck lymphatic metastasis, mostly occurring in the central neck compare, is diagnosed among 20%-90% of patients with differentiated thyroid carcinoma. To definite the anatomic boundaries of the central lymph nodes and their subgroups is significantly important for thyroid carcinoma, such as the determination of surgical extent, the evaluation of prognosis and the choice of different treatment strategies. This paper aims to describe the anatomic boundaries and the components of the central neck compartment and the role of individual subgroups in thyroid carcinoma. We think that the central neck compartment is bounded superiorly by the hyoid bone, inferiorly by the innominate artery on the right and the corresponding axial plane on the left, laterally by the carotid arteries. The superior mediastinal lymph nodes should be the important subgroups of the central neck compartment in thyroid carcinoma. When the prophylactic central lymph node dissection for involved lymph nodes is performed in thyroid carcinoma, we should pay more attention to the superior mediastinal lymph nodes.

Abstract
Objective: To determine whether thyroid hormone (TH) level could also be an independent and incremental predictor of adverse events in patients with hypertrophic cardiomyopathy (HCM). Methods: A total of 982 consecutive patients with HCM at the National Center for Cardiovascular Diseases (China) from October 2009 to December 2013 were included in the present study, and followed up till the end of December 2016. The patients were divided into three groups according to the levels of free triiodothyronine (FT3): the group 1 (FT3≤4.28 pmol/L, n=335), the group 2 (FT3>4.28-<4.79 pmol/L, n=310), and the group 3 (FT3 4.79-6.30 pmol/L, n=337). Results: After a follow-up period of (53.8±14.1) months, 39 patients (4.0%) either suffered death with all causes or received a cardiac transplantation (7.8%, 2.9% and 1.2% of the patients in the group 1, group 2 and group 3, respectively). A multivariable Cox regression analysis revealed that FT3≤4.28 pmol/L was associated with a significantly higher risk of all-cause mortality or cardiac transplantation (HR 8.83, 95% CI 1.115- 69.905,P=0.039) in HCM patients. Conclusions: Low levels of FT3 is a risk factor of adverse events for patients with HCM, indicting a role of FT3 as a marker for assessing the risk of long-term adverse events in these patients.

Abstract
Objective: To determine the value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) on predicting the long-term outcome of patients with hypertrophic cardiomyopathy (HCM) . Methods: NT-proBNP was measured in 831 consecutive patients with HCM at Fuwai Hospital from October 2009 to December 2013 and patients were followed up clinically for (53.3±15.4) months. Patients were divided into 3 groups according to NT-proBNP values: NT-proBNP<860 pmol/L (n=276) , 860 pmol/L≤NT-proBNP≤1 905 pmol/L (n=278) , NT-proBNP>1 905 pmol/L (n=277) . The related baseline data, laboratory examination and echocardiographic results were compared among groups. The primary endpoints of this study were all-cause mortality and cardiac transplantation. Cox proportional hazards model was used to estimate hazard ratio (HR) . Kaplan-Meier analysis was used to evaluate the survival status of patients among the 3 groups. Results: During a median follow-up of (53.3±15.4) months, all-cause mortality or cardiac transplantation occurred in 37 patients (4.5%) , event rate was 1.4% (4/276) , 4.0% (11/278) and 7.9% (22/277) in patients with NT-proBNP<860 pmol/L, 860 pmol/L≤NT-proBNP≤1 905 pmol/L and NT-proBNP>1 905 pmol/L, respectively. Multivariable Cox regression analysis identified that age (HR 1.066, 95%CI 1.027-1.107) and NT-proBNP (HR 1.026, 95% CI 1.010-1.042) were independent predictors of all-cause mortality or cardiac transplantation. Among the 3 groups, the survival rate of the NT-proBNP<860 pmol/L group was the highest,and that of the NT-proBNP>1 905 pmol/L group was the lowest (P<0.01) . Conclusions: The level of NT-proBNP provides clinically relevant information for long-term adverse events risk stratification in patients with HCM.

Abstract
Oxidative stress exhibits a central role in the course of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease commonly found to include a copper/zinc superoxide dismutase (SOD1) gene mutation. Fisetin, a natural antioxidant, has shown benefits in varied neurodegenerative diseases. The possible effect of fisetin in ALS has not been clarified as of yet. We investigated whether fisetin affected mutant hSOD1 ALS models. Three different hSOD1-related mutant models were used: Drosophila expressing mutant hSOD1G85R, hSOD1G93A NSC34 cells, and transgenic mice. Fisetin treatment provided neuroprotection as demonstrated by an improved survival rate, attenuated motor impairment, reduced ROS damage and regulated redox homeostasis compared with those in controls. Furthermore, fisetin increased the expression of phosphorylated ERK and upregulated antioxidant factors, which were reversed by MEK/ERK inhibition. Finally, fisetin reduced the levels of both mutant and wild-type hSOD1 in vivo and in vitro, as well as the levels of detergent-insoluble hSOD1 proteins. The results indicate that fisetin protects cells from ROS damage and improves the pathological behaviors caused by oxidative stress in disease models related to SOD1 gene mutations probably by activating ERK, thereby providing a potential treatment for ALS.

Abstract
Class three semaphorins were originally identified as mediators of axon guidance, which repelled axons and collapsed growth cones. As a member of class three semaphorins, semaphorin3F (Sema3F) has been found to have similar effects on tumor cells and endothelial cells and also is implicated in the signaling of tumor metastasis by forming a complex with neuropilins and plexins. In this study, our laboratory produced a monoclonal antibody against the C-terminal domain of Sema3F (Sema3Fc mAb) using the hybridoma method, expecting to explore the potential role of the antibody and its application in the detection of Sema3F. The capture enzyme-linked immunosorbent assay (ELISA) method indicated that mAb belonged to the IgM subclass and purified Sema3Fc mAb had a titer of 5.12 × 105 against Sema3Fc by indirect ELISA. In addition, results showed that the Sema3Fc mAb could be applied in such experiments as Western blotting, flow cytometry, immunofluorescence, and immunocytochemical staining. It indicates the Sema3Fc mAb is available in the detection of Sema3F with specificity and will help further study the role and mechanism of Sema3F among tumor cells.

Abstract
Six stable C84 isomers satisfying isolated pentagon rule (IPR) have been theoretically identified by infrared (IR), X-ray photoelectron (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectra. The XPS and NEXAFS spectra at the K-edge for all nonequivalent carbon atoms were simulated by the density functional theory method. NEXAFS spectra show stronger dependence than IR and XPS spectra on the six C84 isomers, which can be properly used for isomer identification. Furthermore, spectral components of total spectra for carbon atoms in different local environment have been explored.

Abstract
The single application of 0.5 % clothianidin granules, a novel formulation, was used to control pests in vegetables under a high dose. In this article, residues of clothianidin in cabbage and soil samples under field conditions from Guangzhou, Nanning, and Qianjiang were determined by HPLC. The terminal residues of clothianidin in cabbage were less than the limit of detection (<LOD) at pre-harvest intervals of 30 days, and these values were lower than the maximum residue limit of 0.2 mg kg-1 in cabbage set by the Codex Alimentarius Commission. To test on the influence of the pesticide fertilizers' effect on clothianidin residual, clothianidin granules and fertilizers of chicken manure, urea, and organic fertilizer were mixed into different pesticide fertilizers through their normal field using dosage and evaluate residual influence of clothianidin in different formula. After analysis of variance of the effect factors, the effect of different pesticide types on half-life was not significant, but the effect of sample types was significant. Clothianidin granules and pesticide fertilizers could be safely applied in cabbage under a single high-dose administration.

Abstract
Research into novel one-dimensional (1D) materials and associated structural transitions is of significant scientific interest. It is widely accepted that a 1D system with a short-range interaction cannot have 1D phase transition at finite temperature. Herein, we propose a series of new stable carbon nanotubes by rolling up penta-graphene sheets, which exhibit fascinating well-defined 1D phase transitions triggered by axial strain. Our first-principles calculations show that such penta-graphene nanotubes (PGNTs) are dynamically stable by phonon calculations, but transform from a tri-layer structure to a highly defective single-walled nanotube at low temperature in molecular dynamics simulations. We show that moderate compressive strains can drive structural transitions of (4,4), (5,5), and (6,6) PGNTs, during which the distances of neighboring carbon dimers in the inner shell have a sudden drop, corresponding to dimer-dimer nonbonding to bonding transitions. After such transition, the tubes become much more thermally stable and undergo semiconductor-metal transitions under increasing strain. The band gaps of PGNTs are not sensitive to chirality whereas they can be tuned effectively from visible to short-wavelength infrared by appropriate strain, making them appealing materials for flexible nano-optoelectronics. These findings provide useful insight into unusual phase transitions in low-dimensional systems.

Abstract
Objective: To investigate the correlation between the expression of programmed death-1(PD-1), PD ligand-1(PD-L1), indoleamine 2, 3-dioxygenase 1(IDO-1) and clinical parameters in sinonasal malignant mucosal melanoma (SNM). Methods: Samples from 86 SNM patients who did not receive immune-targeted therapy and radio-chemotherapy were analyzed for PD-1, PD-L1, and IDO-1 expression by immunohistochemistry. Results: High clinical/pathologic staging, brain metastases and advanced age were independent risk factors of poor prognosis. The overall survival rate of SNM without pigment was lower than that with pigment. PD-1, PD-L1 and IDO-1 expression was not correlated with tumor pigmentation, but correlated with different primary site.PD-1, PD-L1 and IDO-1 were expressed in 47.6% (41/86), 53.5% (46/86) and 58.1% (50/86)of SNM samples respectively. PD-1 was associated with brain metastasis. Negative expression of PD-1(P=0.031) and IDO-1(P=0.017 9) correlated with worse disease-free survival. No significant association was found between PD-L1 and prognosis. For stages Ⅲ, ⅣA and ⅣB patients, PD-1 expression was associated with better outcome (P=0.025), but PD-L1 negative and IDO-1 positive patients hadworse outcome (P>0.05). PD-1 positive and IDO-1 negative stage ⅣC patients had poorer overall survival. Conclusions: In SNM patients, clinical/pathologic staging, brain metastases, age and pigmentation were prognostic indicator. IDO-1 and PD-1 can also be used as reference to evaluate prognosis. Anti-IDO-1 targeted therapy may be suitable for middle to late stage patients, while advanced stage patients might benefit from anti-PD-1 targeted therapy. PD-1/PD-L1 and IDO-1 may be considered as joint targeted therapy.The predictive value of PD-L1 requires further study.

Abstract
Objective: To evaluate the clinical characteristics and prognosis of patients with mitral valve prolapse (MVP). Methods: We retrospectively analyzed the clinical characteristics and prognosis of 148 MVP patients who underwent mitral valve surgery in Fuwai hospital from January 2012 to December 2015.The patients were divided into mucoid degeneration group (52 cases) and without mucoid degeneration group(19 cases) according to pathological examination of leaflets and chordate. Results: The clinical symptoms of MVP patients included dyspnea (59.5%(88/148)), chest distress and pain (52.7%(78/148)), and palpitations (36.5% (54/148)). Mitral valve repair was performed in 144 cases (97.3%), and mitral valve replacement was performed in 4 cases (2.7%). Posterior leaflet prolapse was the most common form of MVP (68.9%, 102/148). Pathological examination revealed myxomatous degeneration in 73.2% patients (52/71), fibrosis in 8.5% patients (6/71), and fibrinoid necrosis in 8.5% patients (6/71). Patients with mucoid degeneration had less atrial fibrillation before surgery (5.8%(3/52) vs. 42.1%(8/19), P<0.01), smaller preoperative left atrium diameter ((43.2±6.5) mm vs. (48.2±8.9) mm, P<0.05), more posterior leaflet prolapse (94.2%(49/52) vs. 63.2%(12/19), P<0.01), redundant chordae (26.9%(14/52) vs. 0, P<0.05) and leaflet thickening (76.9%(40/52) vs. 52.6%(10/19), P<0.05) when compared with patients without mucoid degeneration.Echocardiography examination at the postoperative follow-up of 39.0(22.3, 57.0) months revealed smaller left atrium diameter((38.5±7.1) mm vs. (45.3±8.3) mm, P<0.01), left ventricular end-diastolic diameter ((48.9±6.2) mm vs. (57.5±7.6) mm, P<0.01), reduced left ventricular ejection fraction ((61.2±7.1)% vs. (65.1±6.2)%, P<0.01) and less moderate or severe mitral regurgitation (1.4%(2/148) vs. 100.0%(148/148), P<0.01) compared with the corresponding preoperative values. Conclusions: Dyspnea is the main symptom, and mucoid degeneration characterized by redundant chordae and leaflet thickening are the main pathological features of MVP patients.The surgical treatment of MVP patients is related with satisfactory outcome results.

Abstract
Objective: To investigate the clinical features and surgical treatment effect of patients with cardiac cavernous hemangioma. Methods: Clinical data of 9 patients (5 male, aged from 4 to 53 years old) with cardiac cavernous hemangioma, who underwent surgical treatment from November 2002 to March 2015 and the diagnosis of cardiac cavernous hemangioma was confirmed by postoperative histological examination, were retrospectively analyzed. Effects of surgical treatment were analyzed. Results: Four patients were asymptomatic (heart murmur presented in 3 patients during physical examination). Three patients presented with palpitation, chest distress, and short of breath. One patient presented with epigastric discomfort and another patient presented with intermittent fever for more than 10 months. ST and T wave changes of electrocardiogram were found in 2 patients, cardiac mass was detected in the right heart chamber in 5 patients by echocardiography, and no cardiac mass was detected the rest 4 patients. Cardiac masses were resected en bloc, then the adjacent tissues were repaired in 7 patients, and mass was partially resected due to the involvement with adjacent heart structure. No cardiac mass was found during operation in 1 case, impaired mitral valve structure was excised and postoperative pathologically confirmed as cardiac valve cavernous angioma on the excised mitral valve structure. No signs of recurrence or enlargement of cardiac cavernous hemangioma were found during the 11(10, 11)years follow up. Conclusions: There is no specific clinical feature for patients with cardiac cavernous hemangioma. It is difficult to detect the cardiac valve cavernous angioma by echocardiography before surgery. Individualized surgical treatment is associated with good clinical outcome in this patient cohort. However, the clinical features and surgical treatment effect of patients with cardiac cavernous hemangioma still need to investigate in large sample trial.

Abstract
Objective: To explore the clinical characteristics and risk factors of pulmonary hypertension (PH) in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 301 patients admitted in Fuwai Hospital and diagnosed with HOCM were included in our study. Incidence rate and severity of PH were depicted. The study population was divided into two groups (PH group and control group), and the differences in clinical profile were elucidated. Risk factors of PH in patients with HOCM were assessed by multivariate logistic regression analysis. Results: The incidence of PH was 12.3% (37 cases), in which 48.6% patients (18 cases) were mild PH, 40.5% patients (15 cases) were moderate PH, and patients with severe PH accounts for 10.8% (4 cases). Multivariate logistic regression analysis indicated that female(OR=3.95, 95%CI 1.74-8.98, P=0.001), age ≥65 years(OR=3.87, 95%CI 1.16-12.97, P=0.030), history of atrial fibrillation(OR=2.76, 95%CI 1.01-7.57, P=0.049)and moderate or severe mitral regurgitation(OR=6.63, 95%CI 3.02-14.57, P=0.000)were independent risk factors of PH. Stratification according to sex showed that age ≥65 years(OR=7.79, 95%CI 1.35-47.26, P<0.05)and moderate or severe mitral regurgitation(OR=9.83, 95%CI 2.26-42.67, P<0.01)were independent risk factors of PH for male patients; while history of atrial fibrillation(OR=6.32, 95%CI 1.57-25.40, P=0.01)and moderate or severe mitral regurgitation(OR=5.23, 95%CI 1.92-14.26, P<0.01)were independent risk factors of PH for female patients. Risk factors were similar between the mild PH group and moderate to severe PH groups. Conclusion: Compared with patients without PH, HOCM patients complicated with PH were older and with higher percentage of female, and resting obstruction, history of atrial fibrillation and moderate or severe mitral regurgitation. Independent risk factors for PH in obstructive hypertrophic cardiomyopathy patients are female, advanced age, history of atrial fibrillation and moderate or severe mitral regurgitation.

Abstract
AIMS Despite more than a century of research, spinal paralysis remains untreatable via biological means. A new understanding of spinal cord physiology and the introduction of membrane fusogens have provided new hope that a biological cure may soon become available. However, proof is needed from adequately powered animal studies. METHODS AND RESULTS Two groups of rats (n=9, study group, n=6 controls) were submitted to complete transection of the dorsal cord at T10. The animals were randomized to receive either saline or polyethylene glycol (PEG) in situ. After 4 weeks, the treated group had recovered ambulation vs none in the control group (BBB scores; P=.0145). One control died. All animals were studied with somatosensory-evoked potentials (SSEP) and diffusion tensor imaging (DTI). SSEP recovered postoperatively only in PEG-treated rats. At study end, DTI showed disappearance of the transection gap in the treated animals vs an enduring gap in controls (fractional anisotropy/FA at level: P=.0008). CONCLUSIONS We show for the first time in an adequately powered study that the paralysis attendant to a complete transection of the spinal cord can be reversed. This opens the path to a severance-reapposition cure of spinal paralysis, in which the injured segment is excised and the two stumps approximated after vertebrectomy/diskectomies.

Abstract
Burkitt lymphoma (BL) is a highly malignant non-Hodgkin's lymphoma that is closely
related to the abnormal expression of genes. Familial acute myelogenous leukemia
related factor (FAMLF; GenBank accession No. EF413001.1) is a novel
gene that was cloned by our research group, and miR-181b is located in the intron of
the FAMLF gene. To verify the role of miR-181b and
FAMLF in BL, RNAhybrid software was used to predict target site
of miR-181b on FAMLF and real-time quantitative PCR (RQ-PCR) was
used to detect expression of miR-181b and FAMLF in BL patients, Raji
cells and unaffected individuals. miR-181b was then transfected into Raji and CA46
cell lines and FAMLF expression was examined by RQ-PCR and western
blotting. Further, Raji cells viability and proliferation were detected by MTT and
clone formation, and Raji cell cycle and apoptosis were detected by flow cytometry.
The results showed that miR-181b can bind to bases 21–42 of the
FAMLF 5′ untranslated region (UTR), FAMLF was
highly expressed and miR-181b was lowly expressed in BL patients compared with
unaffected individuals. FAMLF expression was significantly and
inversely correlated to miR-181b expression, and miR-181b negatively regulated
FAMLF at posttranscriptional and translational levels. A
dual-luciferase reporter gene assay identified that the 5′ UTR of
FAMLF mRNA contained putative binding sites for miR-181b.
Down-regulation of FAMLF by miR-181b arrested cell cycle, inhibited
cell viability and proliferation in a BL cell line model. Our findings explain a new
mechanism of BL pathogenesis and may also have implications in the therapy of
FAMLF-overexpressing BL.

Abstract
School bullying and campus violence is a widespread social problem in the world. School bullying is characterized by its repeatability and suddenness, which could make the victims suffering from both psychological and health damage, and even affect their personality growth. Government should pay close attention to the reduction and control of school bullying and campus violence by establishing school bullying emergency response system and preparedness plan. The school and teacher's role and legal responsibility in the service and management in schools should be cleared and defined. It is necessary to help teachers conduct early detection and intervention for school bullying, conduct morality, mental health and legal educations in students to teach them to act according to the law and protect themselves according to the law and help them identify and avoid risks, encourage the establishment of rescue facility and web of anti-school bullying by non-government organizations, and set hotline for school bullying incident to reduce the incidence of school bullying.

Abstract
Objective: To evaluate the clinical characteristics and risk factors for atrial fibrillation(AF)in patients with obstructive hypertrophic cardiomyopathy(OHCM). Methods: Patients with OHCM hospitalized in Fuwai Hospital from March 2011 to January 2016 were enrolled in the present study. Each patient underwent examinations including transthoracic echocardiography, body surface electrocardiograph or dynamic electrocardiogram (Holter). Cardiac troponin I (cTNI) and N-terminal pro-brain natriuretic peptide (NT-pro-BNP)levels were tested and clinical profiles were collected.The subjects were divided into two groups (the AF group and non-AF group). Risk factors for AF in patients with OHCM were assessed by multivariate logistic regression analysis. Results: A total of 309 patients were evaluated in the study. Among them, 17.5%( 54/309) patients were with AF.Age[(51.2±10.1)years vs (43.1 ± 14.4)years], New York Heart Association class(NYHA class)(2.8±0.5 vs 2.6±0.6), disease duration[6.0(4.0, 10.0)years vs 3.0(1.0, 6.0)years], left atrial (LA) dimension[(45.1±7.0)mm vs(42.6 ± 7.4)mm]and NT-pro-BNP levels[2 007(1 565, 3 199)pmol/L vs 1 509(729, 2 921)pmol/L]in the AF group were significantly higher than those in the non-AF group (all P<0.05). Multivariate logistic regression analysis indicated that advanced age(OR=1.04, 95% CI 1.01-1.08, P<0.01), higher NYHA class(OR=2.00, 95% CI 1.08-3.70, P<0.05)and longer disease duration(OR=1.08, 95% CI 1.01-1.15, P<0.05)were independent risk factors for AF in patients with OHCM, in which advanced age(OR=1.05, 95% CI 1.02-1.09, P<0.01), higher NYHA class(OR=3.39, 95% CI 1.53-7.54, P<0.01), LA dimension(OR=1.06, 95% CI 1.01-1.12, P<0.05)and longer clinical course(OR=1.12, 95% CI 1.04-1.20, P<0.01)were associated with AF in male patients, and advanced age (OR=1.05, 95% CI 1.01-1.09, P<0.05)and longer disease duration(OR=1.14, 95% CI 1.01-1.28, P<0.01)were associated with AF in female patients when stratified by gender. Conclusion: Advanced age , higher NYHA class and longer clinical duration are independent risk factors for AF in OHCM patients.

Abstract
OBJECTIVE To evaluate the survival outcomes of invasive fungal rhinosinusitis by analyzing the clinical features. METHODS A retrospective analysis was performed for cases of invasive fungal sinusitis proved by histological analysis between March 2006 and November 2015. All relevant factors including interval from the onset of symptoms to initiation of diagnosis, clinical characteristics, features of CT and MRI, treatment and prognosis were collected. A total of 18 patients (10 males; 8 females) were identified. The median age was 54 years old. Three patients suffered from acute invasive fungal sinusitis, while the other 15 suffered from chronic invasive fungal sinusitis. RESULTS The mean duration between onset of symptoms and diagnosis was 5 months. The most common symptom was headache (10/18), followed by visual disturbance (7/18), nasal obstruction (4/18), facial numbness and pain (2/18) and diplopia(2/18). Two patients had diabetes mellitus; one patient had ankylosing spondylitis receiving immunosuppressive drugs treatment for one year. Four patients had the disease confined in the sinus. Complications of this disease included orbital apex involvement in 6 patients, intraorbital and optic nerve involvement in 3 patients, cavernous sinus involvement in 5 patients, pterygopalatine fossa and infratemporal fossa involvement in 5 patients, intracranial extension involvement in 3 patients. Fungal species included aspergillus (15 cases) and mucor (3 cases). Seventeen patients received intravenous antifungal therapy after surgery. The duration of follow-up ranged from 1 to 60 months. Two patients reoccurred and one patient died of the disease. CONCLUSION Endoscopic debridement combined with intravenous antifungals is efficacious in the management of invasive fungal sinusitis.

Abstract
An x-ray imaging crystal spectrometer has been developed on joint Texas experimental tokamak for the measurement of electron and ion temperatures from the Kα spectra of helium-like argon and its satellite lines. A two-dimensional multi-wire proportional counter has been applied to detect the spectra. The electron and ion temperatures have been obtained from the Voigt fitting with the spectra of helium-like argon ions. The profiles of electron and ion temperatures show the dependence on electron density in ohmic plasmas.

Abstract
The present study aimed to investigate the practicability and clinical value of applying laparotomy biliary lithotomy forceps to laparoscopic bile duct exploration (LCBDE) for the surgical treatment of incarcerated calculi. A total of 63 patients were diagnosed with cholecystolithiasis and choledocholithiasis. The present study performed a retrospective analysis of clinical samples from 16 of these patients who had incarcerated calculi at the terminus of the common bile duct, and who had been treated with laparoscopic cholecystectomy and LCBDE. During the procedure, laparotomy biliary lithotomy forceps were used to gently remove the calculi from the common bile duct. Of the surgical procedures that used laparotomy biliary lithotomy forceps, one case was unsuccessful and 15 cases were successful. The results of the present study suggested that it may be clinically advisable to use laparotomy biliary lithotomy forceps to remove incarcerated calculi from the common bile duct during a laparoscopy, since it is easy, economical and effective.

Abstract
To enhance the reductive dechlorination of 1,2-dichloroethane (DCA) in groundwater, substrate injection may be required. However, substrate biodegradation causes groundwater acidification and sulfide production, which inhibits the bacteria responsible for DCA dechlorination and results in an odor problem. In the microcosm study, the effectiveness of the addition of ferrous sulfate (FS), desulfurization slag (DS), and nanoscale zero-valent iron (nZVI) on acidification and sulfide control was studied during reductive dechlorination of DCA, and the emulsified substrate (ES) was used as the substrate. Up to 94% of the sulfide was removed with FS and DS addition (0.25 wt%) (initial DCA concentration = 13.5 mg/L). FS and DS amendments resulted in the formation of a metal sulfide, which reduced the hydrogen sulfide concentration as well as the subsequent odor problem. Approximately 96% of the DCA was degraded under reductive dechlorination with nZVI or DS addition using ES as the substrate. In microcosms with nZVI or DS addition, the sulfide concentration was reduced to less than 15 μg/L. Acidification can be controlled via hydroxide ions production after nZVI oxidation and reaction of free CaO (released from DS) with water, which enhanced DCA dechlorination. The quantitative polymerase chain reaction results confirmed that the microcosms with nZVI added had the highest Dehalococcoides population (up to 2.5 × 10(8) gene copies/g soil) due to effective acidification control. The α-elimination mechanism was the main abiotic process, and reductive dechlorination dominated by Dehalococcides was the biotic mechanism that resulted in DCA removal. More than 22 bacterial species were detected, and dechlorinating bacteria existed in soils under alkaline and acidic conditions.

Abstract
Using ab initio molecular dynamics simulations, we show that oxygen (O) impurities have a noticeable influence on the glass-formation ability (GFA) in Zr2Cu alloy. Cu-centered icosahedral clusters and Zr-centered Kasper polyhedra are the dominate short-range orders in undercooled Zr2Cu liquid which are most likely to be responsible for the glass formation in Zr2Cu systems. When O is introduced, a Zr octahedron is formed around the O impurity. Most of the Zr atoms in the octahedron also serve as the bridging atoms for cross-linked Kasper polyhedral network, resulting in an O-centered medium range order (MRO) structure. Meanwhile, Cu atoms are moved away from the first shell of O-centered octahedral clusters. With 1 at. % O impurities, the fractions of Zr-centered clusters are less affected, while the increase of ideal icosahedral order and decrease of distorted icosahedral order lead to a more stable atomic structure. This result suggests that a low concentration of O impurities would improve the GFA in Zr2Cu alloy. However, when ∼5 at. % O impurities are included, the ideal icosahedral clusters and Zr-centered Kasper polyhedra are seriously suppressed by the formation of O-centered MRO, which can lead to deterioration of GFA. Our analyses provide useful insight into glass formation behavior in O-doped metallic alloy systems.
