Measurement of Azimuthal Anisotropy of Muons from Charm and Bottom Hadrons in pp Collisions at sqrt[s]=13 TeV with the ATLAS Detector

The elliptic flow of muons from the decay of charm and bottom hadrons is measured in pp collisions at sqrt[s]=13  TeV using a data sample with an integrated luminosity of 150  pb^{-1} recorded by the ATLAS detector at the LHC. The muons from heavy-flavor decay are separated from light-hadron decay muons using momentum imbalance between the tracking and muon spectrometers. The heavy-flavor decay muons are further separated into those from charm decay and those from bottom decay using the distance-of-closest-approach to the collision vertex. The measurement is performed for muons in the transverse momentum range 4-7 GeV and pseudorapidity range |η|<2.4. A significant nonzero elliptic anisotropy coefficient v_{2} is observed for muons from charm decays, while the v_{2} value for muons from bottom decays is consistent with zero within uncertainties.

Inhibition of miR-103a-3p suppresses the proliferation in oral squamous cell carcinoma cells via targeting RCAN1

Oral cancer is one of the common cancers worldwide, among which over 90% are oral squamous cell carcinomas (OSCC). MicroRNAs act as critical regulators of cancer development and progression. MiR-103a-3p has been reported to be upregulated in OSCC patients and closely correlated to poor prognosis, yet its roles in the progression of OSCC remain undisclosed. In this study, we knocked down the expression of miR-103a-3p in two OSCC cell lines in vitro, and significantly repressed cell proliferation and cell cycle arrest at the G1 phase were observed, accompanied by decreased proliferating cell nuclear antigen, cyclin D1, cyclin B1 and increased PTEN levels. MiR-103a-3p inhibition also induced apoptosis as evidenced by increased apoptotic cells and upregulated cleaved caspase-9/casapase-3 expression. We established a xenograft model in nude mice and found that miR-103a-3p knockdown also suppressed tumor growth in vivo. Besides, the expression of regulator of calcineurin1 (RCAN1), known as its anti-tumor effect, was negatively correlated with the miR-103a-3p level in OSCC cells. We validated that RCAN1 was a downstream target of miR-103a-3p using the dual-luciferase assay. RCAN1 silencing reversed the cell proliferative inhibition, cell cycle arrest and cell apoptosis induced by miR-103a-3p knockdown. In addition, we found that long non-coding RNA LINC00675 acted as a sponge of miR-103a-3p and promoted the expression of miR-103a-3p targets RCAN1 and PTEN. In summary, miR-103a-3p inhibition represses proliferation and induces apoptosis of OSCC cells through regulating RCAN1, and miR-103a-3p may act as a novel diagnostic marker and therapeutic target for OSCC.

Association of obesity with bone mineral density and osteoporosis in adults: a systematic review and meta-analysis

OBJECTIVES

Results from previous studies investigating the association of obesity with bone mineral density (BMD) and osteoporosis (OP) are inconsistent. The purpose of the present study was to examine whether obesity is associated with BMD and the risk of OP.

STUDY DESIGN

This is a meta-analysis.

METHODS

A computerised literature search was conducted using the PubMed, Web of Science, China National Knowledge Internet (CNKI) (Chinese) and Wanfang (Chinese) databases for relevant articles published in English or Chinese before the end of December 2017. Means with standard deviations and odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs) were computed to estimate the association between obesity and BMD and the risk of OP by using a random-effects model. In addition, a heterogeneity test and sensitivity analysis were conducted.

RESULTS

Adults with obesity had higher BMD than healthy-weight subjects in both the lumbar spine and femoral neck measurement sites. Obesity was positively related to BMD in the two sites, with merged weighted mean difference (WMD) of 0.07 g/cm² in the lumbar spine (95% CI: 0.045, 0.095; P < 0.001; P_{heterogeneity} <0.001; I² = 89.1%) and WMD of 0.087 g/cm² in the femoral neck (95% CI: 0.063, 0.112; P < 0.001; P_{heterogeneity} <0.001; I² = 92.8%). General obesity was negatively related to femoral neck OP, indicating that obesity is a protective factor for OP, with a merged OR of 0.169 (95% CI: 0.132, 0.216; P < 0.001; P_{heterogeneity} = 0.716; I² = 0.0%).

CONCLUSIONS

Adults with obesity had significantly higher BMD than healthy-weight adults. Obesity was positively associated with BMD and negatively correlated with OP.

Quantitative method for estimating stain density in electron microscopy of conventionally prepared biological specimens

Stain density is an important parameter for optimising the quality of ultrastructural data obtained from several types of 3D electron microscopy techniques, including serial block-face electron microscopy (SBEM), and focused ion beam scanning electron microscopy (FIB-SEM). Here, we show how some straightforward measurements in the TEM can be used to determine the stain density based on a simple expression that we derive. Numbers of stain atoms per unit volume are determined from the measured ratio of the bright-field intensities from regions of the specimen that contain both pure embedding material and the embedded biological structures of interest. The determination only requires knowledge of the section thickness, which can either be estimated from the microtome setting, or from low-dose electron tomography, and the elastic scattering cross section for the heavy atoms used to stain the specimen. The method is tested on specimens of embedded blood platelets, brain tissue and liver tissue.

Search for Magnetic Monopoles and Stable High-Electric-Charge Objects in 13 Tev Proton-Proton Collisions with the ATLAS Detector

A search for magnetic monopoles and high-electric-charge objects is presented using 34.4  fb^{-1} of 13 TeV pp collision data collected by the ATLAS detector at the LHC during 2015 and 2016. The considered signature is based upon high ionization in the transition radiation tracker of the inner detector associated with a pencil-shape energy deposit in the electromagnetic calorimeter. The data were collected by a dedicated trigger based on the tracker high-threshold hit capability. The results are interpreted in models of Drell-Yan pair production of stable particles with two spin hypotheses (0 and 1/2) and masses ranging from 200 to 4000 GeV. The search improves by approximately a factor of 5 the constraints on the direct production of magnetic monopoles carrying one or two Dirac magnetic charges and stable objects with electric charge in the range 20≤|z|≤60 and extends the charge range to 60<|z|≤100.

Use of pre-ART laboratory screening to identify renal, hepatic and haematological abnormalities in Côte d'Ivoire

BACKGROUND

High demand for HIV-services and extensive clinical guidelines force health systems in low-resource settings to dedicate resources to service delivery at the expense of other priorities. Simplifying services may reduce the burden on health systems and pre-antiretroviral therapy (ART) laboratory screening is among the services under consideration for simplification.

METHODS

We assessed the frequencies of conditions linked to ART toxicities among 34,994 adult, ART-naïve patients with specimens referred to the RETRO-CI laboratory in Abidjan, Côte d'Ivoire between 1998 and 2017. Screening included tests for serum creatinine, alanine aminotransferase (ALT) and haemoglobin (Hb) to identify renal dysfunction (estimated glomerular filtration rate < 50 mL/min), hepatic abnormalities (ALT > 5× upper limit of normal) and severe anaemia (Hb < 6.5 g/dL), respectively. We considered screening results across four eras and identified factors associated with the conditions in question.

RESULTS

The prevalence of renal dysfunction, hepatic abnormalities and severe anaemia were largely unchanged over time and just 8.4% of patients had any of the three conditions. Key factors associated with renal dysfunction and severe anaemia were age > 50 years (adjusted odds ratio (aOR): 2.53; 95% confidence interval (CI): 2.19-2.92; P < 0.001) and CD4 < 100 cells/µl (aOR: 2.57; 95% CI: 2.30-2.88; P < 0.001).

CONCLUSION

The relative infrequency of conditions linked to toxicity in Côte d'Ivoire supports the notion that simplification of pre-ART laboratory screening may be undertaken with limited negative impact on identification of adverse events. Targeted screening may be a feasible strategy to balance detection of conditions associated with ART toxicities with simplification of services.

A competing-risks nomogram and recursive partitioning analysis for cause-specific mortality in patients with esophageal neuroendocrine carcinoma

The objective of this study is to estimate the probability of cause-specific mortality using a competing-risks nomogram and recursive partitioning analysis in a large population-based cohort of patients with esophageal neuroendocrine carcinoma. The surveillance, epidemiology and end results database was used to identify 162 patients diagnosed with esophageal neuroendocrine carcinoma from 1998 to 2014. We estimated a cumulative incidence function for cause-specific mortality. A nomogram was constructed by using a proportional subdistribution hazard model, validated using bootstrap cross-validation, and evaluated with a decision curve analysis to assess its clinical utility. Finally, we performed risk stratification using a recursive partitioning analysis to divide patients with esophageal neuroendocrine carcinoma into clinically useful prognostic groups. Tumor location, distant metastasis, surgery, radiotherapy, and chemotherapy were significantly associated with cause-specific mortality. The calibration plots demonstrated good concordance between the predicted and actual outcomes. The discrimination performance of a Fine-Gray model was evaluated by using the c-index, which was 0.723 for cause-specific mortality. The decision curve analysis ranged from 0.268 to 0.968 for the threshold probability at which the risk model provided net clinical benefits relative to hypothetical all-screening and no-screening scenarios. The risk groups stratified by a recursive partitioning analysis allowed significant distinction between cumulative incidence curves. We determined the probability of cause-specific mortality in patients with esophageal neuroendocrine carcinoma and developed a nomogram and recursive partitioning analysis stratification system based on a competing-risks model. The nomogram and recursive partitioning analysis appear to be suitable for risk stratification of cause-specific mortality in patients with esophageal neuroendocrine carcinoma and will help clinicians to identify patients at increased risk of cause-specific mortality to guide treatment and surveillance decisions.

[Long-term efficacy analysis of laparoscopic-assisted anorectoplasty for high and middle imperforate anus]

Objective: To explore the long-term efficacy of laparoscopic-assisted anorectoplasty and conventional anorectoplasty in the treatment of children with high and middle anal atresia. Methods: A retrospective cohort study was used. Inclusion criteria: (1) children with high and middle anal atresia; (2) complicated with rectourethral or rectovesical fistula; (3) complete follow-up data. Exclusion criteria: (1) complicated with 21-trisomy; (2) cerebral palsy and other mentaldisabilities; (3) Currarino syndrome; (4) FG syndrome. Clinical data of 88 patients with middle and high anal atresia, who complicated with rectourethral fistula or rectovesical fistula, and underwent anoplasty at Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from January 2009 to June 2014 were enrolled in the study and analyzed. There were 24 cases with middle atresia and 64 cases with high atresia. All the cases were divided into 2 groups based on the operative method: laparoscopic group (laparoscopic-assisted anorectoplasty, 49 cases), pena group (posterior sagittal anorectoplasty, 39 cases). The demographic features of two groups were comparable. There were no statistically significant differences in gender, age, body mass, classification of anomaly types and sacral ratio (all P>0.05). Student t test and Chi square tests were used to compare the surgical conditions (operative time, postoperative hospital stay and complications), anal function (Kelly score), constipation (Krickenbeck constipation score) and anorectal pressure. Results: Children of both groups all completed operation ssuccessfully. There were no statistically significant differences between laparoscopic group and pena group in the operative time [(120±31) minutes vs. (112±23) minutes, t=1.343, P=0.091] and postoperative hospital stay [(7.1±2.3) days vs. (10.7±3.3) days, t=6.021, P=1.000]. Complications were more common in the pena group [16.3% (8/49) vs. 35.9% (14/39), χ(2)=4.436, P=0.035]. The main complications in laparoscopic group were anal prolapse (8.2%, 4/49) and anal stenosis (6.2%, 3/49), while in pena group were anal stenosis (12.8%, 5/39) and perioperative perianal skin erosion (10.3%, 4/39). As for the anal function, the degree of feces, defecation control and sphincter contractility, the single scoring differences of Kelly scoring system were not statistically significant between the two groups, but the proportion of good function in the laparoscopic group was higher than that in the pena group [67.3% (8/49) vs. 38.5% (15/39), χ(2)=7.308, P=0.007]. Constipation occurred in 6 (12.2%) patients in the laparoscopic group, of whom 5 were improved by diet regulation and 1 required laxatives, while 9 (23.1%) patients developed constipation in the pena group, of whom 4 were improved by diet regulation and 5 required long-term laxatives. The difference of constipation ratio was not statistically significant (χ(2)=1.802, P=0.180). There were no cases of Krickenbeck constipation grade 3. Compared to the pena group, the laparoscopic group had higher anal resting pressure [(33.35±9.69) mmHg vs. (27.68±10.74) mmHg, t=2.599, P=0.011], higher dilating pressure [(9.00±5.61) mmHg vs.(6.51±3.24) mmHg, t=2.462, P=0.016], higher maximal squeeze pressure [(65.80±17.23) mmHg vs. (56.74±18.93) mmHg, t=2.389, P=0.019] and longer maximal contraction time [(21.16±5.02) seconds vs. (18.44±7.24) seconds, t=2.079, P=0.041]. The rectal resting pressure [(5.36±3.00) mmHg vs. (4.61±3.93) mmHg, t=1.015, P=0.312] was not statistically significantly different. Conclusions: Compared with posterior sagittal anorectoplasty, laparoscopic-assisted anorectoplasty in the treatment of high and middle anal atresia has better long-term efficacy with less perioperative complications.

Enhanced β-glucan and pullulan production by Aureobasidium pullulans with zinc sulfate supplementation

The effects of mineral salts on the production of exopolysaccharides, including β-glucan and pullulan, by Aureobasidium pullulans CCTCC M 2012259 were investigated. Zinc sulfate at certain concentrations decreased dry biomass but favored to the biosynthesis of both exopolysaccharides. When 100 mg/L zinc sulfate was added to the fermentation medium, production of β-glucan and pullulan increased by 141.7 and 10.2%, respectively, when compared with that noted in the control without zinc sulfate addition. To reveal the physiological mechanism underlying improved β-glucan and pullulan production, key enzymes activities, energy metabolism substances, intracellular uridine diphosphate glucose (UDPG) levels, and gene expression were determined. The results indicated that zinc sulfate up-regulated the transcriptional levels of pgm1, ugp, fks, and kre6 genes, increased activities of key enzymes involved in the biosynthesis of UDPG, β-glucan and pullulan, enhanced intracellular UDPG content, and improved energy supply, all of which contributed to the increment in β-glucan and pullulan production. The present study not only provides a feasible approach to improve the production of exopolysaccharides but also contributes to better understanding of the physiological characteristics of A. pullulans.

Edoxaban for treatment of venous thromboembolism in patient groups with different types of cancer: Results from the Hokusai VTE Cancer study

BACKGROUND

The safety and efficacy of edoxaban and dalteparin is unclear for several cancer groups.

METHODS

We evaluated the occurrence of the primary outcome in large cancer groups. The primary outcome was the composite of recurrent VTE or major bleeding over 12 months.

RESULTS

In patients with gastrointestinal cancer, the primary outcome occurred in 19.4% patients given edoxaban and in 15.0% given dalteparin (risk difference [RD], 4.4%; 95%-CI, -4.1% to 12.8%). The corresponding rates for edoxaban and dalteparin were 10.4% and 10.7% for lung cancer (RD, -0.3%; 95%-CI, -10.0% to 9.5%), 13.6% and 12.5% for urogenital cancer (RD, 1.1; 95%-CI, -10.1-12.4), 3.1% and 11.7% for breast cancer (RD, -8.6; 95%-CI, -19.3-2.2), 8.9% and 10.9% for hematological malignancies (RD, -2.0; 95%-CI, -13.1-9.1), and 10.4% and 17.4% for gynecological cancer (RD, -7.0; 95%-CI, -19.8-5.7). In the subgroup of gastrointestinal cancer, edoxaban was associated with a 3.5% lower absolute risk of recurrent VTE and a 7.9% higher risk of major bleeding.

CONCLUSION

Edoxaban has a similar risk-benefit ratio to dalteparin in most cancer groups. In those with gastrointestinal cancer, the lower risk of recurrent VTE and the advantages of oral therapy need to be balanced against the increased risk of major bleeding.

Observation of Electroweak Production of a Same-Sign W Boson Pair in Association with Two Jets in pp Collisions at sqrt[s]=13 TeV with the ATLAS Detector

This Letter presents the observation and measurement of electroweak production of a same-sign W boson pair in association with two jets using 36.1  fb^{-1} of proton-proton collision data recorded at a center-of-mass energy of sqrt[s]=13  TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed in the detector fiducial phase-space region, defined by the presence of two same-sign leptons, electron or muon, and at least two jets with a large invariant mass and rapidity difference. A total of 122 candidate events are observed for a background expectation of 69±7 events, corresponding to an observed signal significance of 6.5 standard deviations. The measured fiducial signal cross section is σ^{fid}=2.89_{-0.48}^{+0.51}(stat)_{-0.28}^{+0.29}(syst)  fb.

[Analysis of early renal damage markers under different renal ultrasonic manifestations in gout patients]

Objective: To observe the relationship between early renal damage markers and renal ultrasonic manifestations in gout patients, and whether early renal damage is reversible after uric acid-reducing treatment. Methods: The gout patients from the Department of Rheumatology of Beijing Haidian Hospital and Peking University People's Hospital between July 2016 and December 2017 were recruited in this study. According to the results of renal ultrasonography, the patients were divided into the following three groups. Group A was normal. Group B was punctate crystallization. Group C was renal calculi. Each group included 30 patients. The patients in group B and group C who could insist on regular uric acid-reducing treatment for one year were selected. The levels of urinary RBP, β(2)-MG and NAG were measured in different groups and one year before and after uric acid-reducing treatment. Results: The urinary concentration of β(2)-MG in group A, group B and group C were (128.59±107.32), (316.08±207.41) and (311.25±162.85)mg/L, respectively. There were significant differences among the three groups (P<0.001). The urinary concentration of NAG were (13.41±5.12)U/L,(17.88±6.19)U/L and (18.48±9.84)U/L, respectively. There were differences among the three groups (P<0.01).There was no significant difference in urinary RBP concentration among the three groups (P=0.188). After one year of uric acid-reducing treatment, the levels of urinary RBP, β(2)-MG and NAG were lower than that before treatment. There were significant differences before and after treatment in each group (P<0.05). Compared with group C, the levels of urinary β(2)-MG and NAG were decreased in group B after uric acid-reducing treatment (all P<0.05). Conclusions: Renal ultrasonography is helpful for the diagnosis of early renal damage in gout patients. Early renal damage markers in gout patients decreased after uric acid-reducing treatment, suggesting that early renal damage can be reversible if early diagnosis and timely treatment can be made in gout patients.

[Combined anluohuaxianwan and entecavir treatment significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection]

Objective: To explore the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection who received entecavir alone or in combination with anluohuaxianwan for 78 weeks. Methods: Patients with chronic HBV infection were randomly treated with entecavir alone or in combination with anluohuaxian for 78 weeks. Ishak fibrosis score was used for blind interpretation of liver biopsy specimens. The improvement in liver fibrosis condition before and after the treatment was compared. Student's t test and non-parametric test (Mann-Whitney U-Test and Kruskal-Wallis test) were used to analyze the measurement data. The categorical variables were analyzed by Chi-square test method and Spearman's rank correlation coefficient was used to test bivariate associations. Results: Liver fibrosis improvement rate after 78 weeks of treatment was 36.53% (80/219) and the progression rate was 23.29% (51/219). The improvement of liver fibrosis was associated to the degree of baseline fibrosis and treatment methods (P < 0.05). The improvement rate of hepatic fibrosis in patients treated with anluohuaxianwan combined with entecavir at baseline F < 3 (54.74%, 52/95) was significantly higher than that in patients treated only with entecavir (33.33%, 16/48), P = 0.016 and the progression rate of hepatic fibrosis (13.68%, 13/95) was lower than that in patients treated alone (18.75%, 9/48), P = 0.466. In patients with baseline F < 3, the proportion of patients with improved and stable liver fibrosis in the combined treatment group (68.1%, 32/47) was higher than that in the treatment group alone (51.7%, 15/29). Conclusion: Combined anluohuaxianwan and entecavir treatment can significantly improve the improvement rate of liver fibrosis in patients with chronic hepatitis B virus infection. Furthermore, it has the tendency to improve the stability rate and reduce the rate of progression of liver fibrosis.

Porcine insulin receptor substrate 2: molecular cloning, tissues distribution, and functions in hepatocyte and aortic endothelial cells

Insulin receptor substrate 2 (IRS-2) modulates the phosphatidylinositol 3-kinase (PI3K)/Akt pathway, which controls the suppression of gluconeogenic genes; IRS-2 is also a critical node of insulin signaling. Because of the high homology between pig and human IRS-2, we investigated the expression pattern and function of porcine IRS-2. QPCR and immunoblotting were used to detect the IRS-2 expression level in different tissues. There were high IRS-2 levels in the cerebral cortex, hypothalamus, and cerebellum in the central nervous system. In peripheral tissues, IRS-2 was expressed at relatively high levels in the liver. Immunohistochemistry analysis revealed that IRS-2 was mainly distributed in the hypothalamus and cerebral cortex. Furthermore, IRS-2 knockdown porcine hepatocytes and porcine aortic endothelial cells (PAECs) were generated. The IRS-2 knockdown induced abnormal expression of genes involved in glycolipid metabolism in hepatocytes and reduced the antiatherosclerosis ability in PAECs. In addition, we disrupted IRS-2 in porcine embryonic fibroblasts (PEFs) using the CRISPR/Cas9 genome editing system, before finally generating IRS-2 knockout embryos by somatic cell nuclear transfer (SCNT). Taken together, our results indicate that IRS-2 might be a valuable target to establish diabetes and vascular disease models in the pig.

[Quantitative study on the development of fetal ventricles and cisterna magna in second and third trimesters with MRI]

Objective: To analyze the changes of growth and development of normal fetal ventricles and cisterna magna with gestational age(GA) and the correlation with fetal gender in the second and third trimester,and establish the MR prenatal diagnosis reference standards. Methods: A total of 633 fetuses (mean GA (27.0±4.1) weeks (18.9-40.6 weeks))without central nervous system abnormalities were retrospectively collected from the Obstetrics and Gynecology Hospital of Fudan University from June 2012 to August 2017. The lateral ventricle trigonometric width (LVTW), third ventricle width (TVW), fourth ventricle width (FVW), anterior-posterior diameter of the fourth ventricle(APDFV), cavum septum pellucidum width (CSPW) and cisterna magna width (CMW) were obtained in the standard measure planes on MR image.The correlation between the biometrics and GA and the correlation between the biometrics and fetal gender were analyzed respectively, and the normal reference values of the biometrics were calculated. Spearman correlation analysis, Pearson correlation analysis,linear regression analysis, independent samples t-test and paired samples t-test were used for statistic analysis. Results: (1)Fetal LLVTW,RLVTW,TVW,CSPW and CMW in second and third trimesters were correlated with GA at medium and low levels(the correlation coefficient r were 0.311, 0.277, 0.207, 0.226, 0.295, respectively, all P<0.01). FVW and APDFV were statistically correlated with GA, and the linear regression equations were as follows: y=0.022×GA-0.043 (adjusted R(2)=0.642); y=0.018×GA-0.159 (adjusted R(2)=0.690). (2)Fetal LLVTW,RLVTW,FVW,APDFV and CSPW were not correlated with fetal gender in second and third trimesters(r=-0.078,-0.057,-0.087,-0.004 and 0.024, P=0.124,0.258,0.085,0.931 and 0.618, all P>0.05). TVW and CMW were statistically correlated with fetal gender(r=-0.310, -0.180, P=0.000, 0.006, all P<0.05). (3) The mean values of LLVTW and RLVTW were (0.71±0.13) cm and (0.68±0.13) cm, respectively, and significant difference was found between them(t=3.180, P=0.002). The mean value of CSPW was (0.59±0.15) cm. And the mean values of male and female fetuses for TVW and CMW were (0.17±0.05) cm, (0.16±0.06) cm and (0.68±0.15) cm, (0.58±0.15) cm, respectively. The corresponding prenatal MRI diagnostic criteria were as follows: LLVTW 1.1 cm, RLVTW 1.0 cm, CSPW 1.0 cm, TVW 0.3 cm, CMW (male 1.1 cm, female 1.0 cm). Conclusions: The normal fetal ventricles and cisterna magna are increased with the GA in the second and third trimesters. TVW and CMW are related to fetal gender. The establishment of normal reference values of fetal ventricles and cisterna magna based on GA and fetal gender are conducive to enhance the accuracy of MRI prenatal diagnosis.

Selective cyclooxygenase-2 inhibitor NS-398 attenuates myocardial fibrosis in mice after myocardial infarction via Snail signaling pathway

OBJECTIVE

The role of NS-398 in Snail pathway of myocardial cells in mice after myocardial infarction and its effect on myocardial fibrosis were investigated in this study.

MATERIALS AND METHODS

C57BL/6 mice were selected to establish mouse models of myocardial infarction with permanent ligation of anterior descending branch and sham-operation models without ligation. After successful establishment of models, 30 mice were randomly divided into sham-operation group, myocardial infarction group and drug intervention group. The drug intervention group was treated with intraperitoneal injection of NS-398 (5 mg/kg) at 1 week after modeling for 3 weeks. The survival status of mice after operation was monitored, the cardiac function was detected via echocardiography, the collagen levels in heart tissue pathological sections were detected via Masson staining and Sirius red staining. Moreover, the expressions of Snail and type I collagen levels were detected via immunohistochemistry, and the Snail protein expression level and the activity and expression level of E-cadherin protein were detected via Western blotting.

RESULTS

At 4 weeks after establishment of myocardial infarction model, the fibrosis reaction was obvious, and the cardiac function was decreased, accompanied with Snail activation. The administration of NS-398 for 3 weeks inhibited the Snail activity expression and significantly improved the fibrosis degree after infarction. However, it did not improve the cardiac function. Inhibiting Snail improved the fibrosis reaction after infarction, in which Snail/E-cadherin signaling pathway was involved.

CONCLUSIONS

NS-398 improves the myocardial fibrosis in mice after myocardial infarction through inhibiting the Snail signaling pathway.

Observation of Light-by-Light Scattering in Ultraperipheral Pb+Pb Collisions with the ATLAS Detector

This Letter describes the observation of the light-by-light scattering process, γγ→γγ, in Pb+Pb collisions at sqrt[s_{NN}]=5.02  TeV. The analysis is conducted using a data sample corresponding to an integrated luminosity of 1.73  nb^{-1}, collected in November 2018 by the ATLAS experiment at the LHC. Light-by-light scattering candidates are selected in events with two photons produced exclusively, each with transverse energy E_{T}^{γ}>3  GeV and pseudorapidity |η_{γ}|<2.4, diphoton invariant mass above 6 GeV, and small diphoton transverse momentum and acoplanarity. After applying all selection criteria, 59 candidate events are observed for a background expectation of 12±3 events. The observed excess of events over the expected background has a significance of 8.2 standard deviations. The measured fiducial cross section is 78±13(stat)±7(syst)±3(lumi)  nb.

Comparison of Fragmentation Functions for Jets Dominated by Light Quarks and Gluons from pp and Pb+Pb Collisions in ATLAS

Charged-particle fragmentation functions for jets azimuthally balanced by a high-transverse-momentum, prompt, isolated photon are measured in 25  pb^{-1} of pp and 0.49  nb^{-1} of Pb+Pb collision data at 5.02 TeV per nucleon pair recorded with the ATLAS detector at the Large Hadron Collider. The measurements are compared to predictions of Monte Carlo generators and to measurements of inclusively selected jets. In pp collisions, a different jet fragmentation function in photon-tagged events from that in inclusive jet events arises from the difference in fragmentation between light quarks and gluons. The ratios of the fragmentation functions in Pb+Pb events to that in pp events are used to explore the parton color-charge dependence of jet quenching in the hot medium. In relatively peripheral collisions, fragmentation functions exhibit a similar modification pattern for photon-tagged and inclusive jets. However, photon-tagged jets are observed to have larger modifications than inclusive jets in central Pb+Pb events.

[Introduction to PRISMA-CI extension statement and checklist systematic reviews on complex interventions]

Comprehensive interventions have been widely used in health system, public health, education and communities and have become increasingly focus of systematic reviews. There have been many reporting guidelines about systematic reviews, but they do not take the features of comprehensive interventions in medical area into consideration. As a result, PRISMA-CI has been developed as an extension of PRISMA, which adds or modifies the essential items of PRISMA. This paper introduces the items of PRISMA-CI and explains the items with an example to help authors, publishers, and readers understand PRISMA-CI and use it in systematic reviews on comprehensive interventions. As it become more and more popular with comprehensive interventions, PRISMA-CI will provide important structure and guidance for its systematic review and Meta-analysis.

Phase transition in phase transition lines of quantum XY model

Phase transitions in quantum systems, including symmetry breaking and topological types, always associate with gap closing and opening. We analyze the topological features of the quantum phase boundary of the XY model in a transverse magnetic field. Based on the results from graphs in the auxiliary space, we find that gapless ground states at boundary have different topological characters. On the other hand, in the framework of Majorana representation, the Majorana lattice is shown to be two coupled SSH chains. The analysis of the quantum fidelity for the Majorana eigen vector, which is shown to be identical to the square of that for ground states of the XY model, indicates the signature of the gapless phase transition (GPT). Furthermore analytical and numerical results for second-order derivative of groundstate energy density show that such a GPT obeys scaling behavior.

Combination of Searches for Invisible Higgs Boson Decays with the ATLAS Experiment

Dark matter particles, if sufficiently light, may be produced in decays of the Higgs boson. This Letter presents a statistical combination of searches for H→invisible decays where H is produced according to the standard model via vector boson fusion, Z(ℓℓ)H, and W/Z(had)H, all performed with the ATLAS detector using 36.1  fb^{-1} of pp collisions at a center-of-mass energy of sqrt[s]=13  TeV at the LHC. In combination with the results at sqrt[s]=7 and 8 TeV, an exclusion limit on the H→invisible branching ratio of 0.26(0.17_{-0.05}^{+0.07}) at 95% confidence level is observed (expected).

miRNA-138 regulates MLK3/JNK/MAPK pathway to protect BV-2 cells from H2O2-induced apoptosis

BACKGROUND

miR-138 is one of the down-regulated miRNAs during acute spinal cord injury. Mixed lineage kinase 3 (MLK3), a key factor of jun N-terminal kinase (JNK)/mitogen-activated protein kinase (MAPK) pathway, is the target of miR-138. The aim of this study was to investigate the role of miR-138 in H2O2-treated BV-2 cells.

METHODS

Murine microglia BV-2 cells were treated with H2O2 and tested for cell viability and miR-138 expression. The cells were then transfected with miR-138 agomir or miR-138 antagomir, and treated with 200 μM H2O2 for 24 h. The cellular apoptosis was detected by Aennexin V/PI staining. Expression of miR-138, MLK3, and other factors of JNK/MAPK pathway was detected.

RESULTS

After treatment of various concentrations of H2O2, the cell viabilities were reduced, and miR-138 expression was down-regulated. Compared to the control cells, over-expressing miR-138 in BV-2 cells reduced apoptosis rate from 24.2 % to 11.9 %. Western blot further showed that JNK, p-JNK, c-jun, p-c-jun, p38 MAPK, and p-p38 MAPK were down-regulated. Expression of pro-apoptosis factors iNOS and COX-2 were also down-regulated. Transfection of miR-138 antagomir produced the opposite effect of the transfection of miR-138 agomir.

CONCLUSION

miR-138 was able to reduce H2O2-induced apoptosis in BV-2 cells. The protective effect was related to the down-regulation of MLK3 proteins and sequentially inhibiting JNK/MAPK signaling pathway (Fig. 3, Ref. 27). Text in PDF www.elis.sk.

Search for the Production of a Long-Lived Neutral Particle Decaying within the ATLAS Hadronic Calorimeter in Association with a Z Boson from pp Collisions at sqrt[s]=13 TeV

This Letter presents a search for the production of a long-lived neutral particle (Z_{d}) decaying within the ATLAS hadronic calorimeter, in association with a standard model (SM) Z boson produced via an intermediate scalar boson, where Z→ℓ^{+}ℓ^{-} (ℓ=e, μ). The data used were collected by the ATLAS detector during 2015 and 2016 pp collisions with a center-of-mass energy of sqrt[s]=13  TeV at the Large Hadron Collider and correspond to an integrated luminosity of 36.1±0.8  fb^{-1}. No significant excess of events is observed above the expected background. Limits on the production cross section of the scalar boson times its decay branching fraction into the long-lived neutral particle are derived as a function of the mass of the intermediate scalar boson, the mass of the long-lived neutral particle, and its cτ from a few centimeters to one hundred meters. In the case that the intermediate scalar boson is the SM Higgs boson, its decay branching fraction to a long-lived neutral particle with a cτ approximately between 0.1 and 7 m is excluded with a 95% confidence level up to 10% for m_{Z_{d}} between 5 and 15 GeV.

Beclin 1, LC3, and p62 expression in paraquat-induced pulmonary fibrosis

Paraquat (PQ) is a highly toxic herbicide to humans. Pulmonary fibrosis is one of the most typical features of PQ poisoning, which develops from several days to weeks after ingestion. However, the mechanism of fibrosis is still unclear. In this study, we aimed to determine expressions of autophagy-related markers Beclin 1, microtubule-associated protein light chain 3 (LC3), and p62 in PQ-poisoned lungs and to explore the role of autophagy in pulmonary fibrosis induced by PQ. We detected markers of lung fibrosis and expressions of autophagy-related protein in the specimens from eight fatal cases of PQ poisoning by hematoxylin and eosin staining, Masson's trichrome staining, and immunohistochemistry. Based on the staining results of lung fibrosis, these cases were divided into two groups, fibrosis and non-fibrosis groups. The correlation between autophagy protein expressions and pulmonary fibrosis was examined. The results demonstrated that the autophagy-related proteins were significantly expressed in fibrosis group compared with the non-fibrosis group. There was a significantly positive correlation between these protein expressions and severity of lung fibrosis. In conclusion, autophagy dysfunction may be involved in lung fibrogenesis caused by PQ poisoning. This may be a promising clue for understanding the molecular mechanism underlying PQ-induced lung fibrosis and provide evidence for treating fibrosis by regulating the level of autophagy.

Prevalence, distribution and risk factors of farmer reported swine influenza infection in Guangdong Province, China

A cross-sectional study was undertaken to better understand the husbandry, management and biosecurity practices of pig farms in Guangdong Province (GD), China to identify risk factors for farmer reported swine influenza (SI) on their farms. Questionnaires were administered to 153 owners/managers of piggeries (average of 7 from each of the 21 prefectures in GD). Univariable and multivariable logistic regression analyses were used to identify risk factors for farmer reported SI in piggeries during the six months preceding the questionnaire administration. The ability of wild birds to enter piggeries (OR 2.50, 95% CI: 1.01-6.16), the presence of poultry on a pig-farm (OR 3.24, 95% CI: 1.52-6.94) and no biosecurity measures applied to workers before entry to the piggery (OR 2.65, 95% CI: 1.04-6.78) were found to increase the likelihood of SI being reported by farmers in a multivariable logistic regression model. The findings of this study highlight the importance of understanding the local pig industry and the practices adopted when developing control measures to reduce the risk of SI to pig farms.

Classification of water contamination developed by 2-D Gabor wavelet analysis and support vector machine based on fluorescence spectroscopy

The identification of the specific categories of pollutants in the urban water supply system is necessary. Traditional detection methods are based mainly on common water quality indicators. However, inspecting these water quality indicators is made difficult by issues such as long analysis time, insufficient sensitivity, need for reagents, and generation of waste liquid. These problems hinder high-frequency water detection and monitoring. In this study, three-dimensional (3D) fluorescence spectroscopy is adopted as a monitoring method for water quality. An identification method based on two-dimensional (2D) Gabor wavelets and support vector machine (SVM) multi-classification is also proposed. The Delaunay triangulation method for interpolation is used to pre-process 3D fluorescence spectra and thereby eliminate Rayleigh scattering and Raman scattering. A 2D Gabor wavelet function generated by filters of different scales and rotation angles is proposed to extract the features of the spectra. The block statistics method, based on Gabor feature description, is employed to enhance the efficiency in describing spectra features. Then, multiple SVM classifiers are used in pollutant classification and recognition. By comparing the proposed method with principal component analysis, which is a commonly used feature extraction method, this study finds that the application of 2D Gabor wavelets and block statistics can effectively describe the characteristics of 3D fluorescence spectra. Moreover, 2D Gabor wavelets achieve high classification accuracy, especially for substances with closely positioned or overlapping characteristic peaks.

Abstract P4-04-08: Genomic profiling of 304 treatment-naïve Chinese breast cancer patients: A comparison of Chinese and TCGA cohorts

Background: The complexity of BC at the clinical, morphological and molecular level has been well recognized. Molecular profiling, which reveals the intrinsic biology among subtypes, has significantly advanced the management of this disease. However, previous studies have provided very limited molecular data on Chinese breast cancer patients.

Methods: We performed targeted sequencing using a panel consisting of 36 BC related genes to interrogate the genomic landscape of 304 consecutive treatment-naïve Chinese BC patients and compared our results to the TCGA data set.

Results: Comparing to TCGA, our cohort had significantly fewer patients with triple negative breast cancer (8.2% vs 15.5% p=0.002). The most prominent genomic difference was our cohort had significantly higher TP53mutation frequency in HR+/HER2- and HR+/HER2+ groups. The composition of TP53 mutations also differed significantly between two cohorts in HR+/HER2- group, with TCGA cohort having missense mutation as the predominant mutation; whereas, in our cohort, nonsense and frameshift mutations were predominant. We classified the most populated and diverse group of HR+/HER2- cancer into 4 subgroups based on molecular signature. The clinical significance of this proposed classification was confirmed by differences in overall survival using data from the TCGA.

Conclusions:We identified distinctive genomic patterns associated with Chinese breast cancer patients compared to TCGA data, suggesting the importance of mutation-based stratification according to ethnic status. To the best of our knowledge, this is one of the largest study of Chinese BC patients that interrogated the spectrum of mutational events and correlated these molecular signatures with clinical outcomes.

Abstract P5-04-25: Characterization of FGFR1/2 genetic alterations reveals novel fusions of FGFR1 in Chinese breast cancer

Background: Deregulation of fibroblast growth factor receptor 1 (FGFR1) signalling has been extensively studied in various tumor types, and has been implicated in driving endocrine resistance in breast cancer. Genetic alterations of FGFR1, especially FGFR1 amplification, is one of particularly important mechanisms leading to enhanced FGFR signaling in breast cancer. However, the prevalence of FGFR1/2 genetic variations in Chinese breast cancer patients has not been well explored.

Methods: To investigate the characteristics of FGFR1 and FGFR2 genetic variations in Chinese breast cancer, we employed customized next-generation sequencing panel to screen the somatic mutation or copy number variations of FGFR1/2 in primary breast cancer tissues by using two ongoing breast cancer Cohorts, in which we have recruited 289 of early breast cancer patients (EBC Cohort) and 74 of advanced breast cancer patients (ABC Cohort).

Results: In EBC Cohort, we found FGFR1 amplification in 9.0% (26/289) patients and FGFR2 amplification in 2.1% (6/289) patients, and also found 3 of somatic FGFR1 mutations (FGFR1 p.W4C; p.E334K; p.V396I ) and 2 of FGFR2 mutations (FGFR2 p.S702L; p.Y779*). Unlike the comparable prevalence of FGFR2 genetic variations in 2.8% (8/289) of EBC Cohort and 2.7% (2/74; one amplification event and one FGFR2 p.E499D mutation) of ABC Cohort, there were more FGFR1 genetic alterations in ABC Cohort (27%; 20/74 patients; p&lt;0.001), including 19 events of FGFR1 amplification and 1 of FGFR1 c.2186+20G&gt;A intron mutation. More importantly, we identified 5 novel FGFR1 fusion genes in our cohorts, including TACC1-FGFR1, FGFR1-KCNU1, FGFR1-MIR1268A, FGFR1-LZTS1-AS1 and FGFR1-RNF5P1. Although FGFR1-TACC1 fusion gene has been previously reported in breast cancer and TACC1 is fused to the C-terminal of FGFR1 protein leading to aberrant activation of FGFR1, we found TACC1 was fused to the N-terminal of FGFR1 at exon 6 of FGFR1 in our study. In addition, we identified and verified FGFR1-MIR1268A fusion gene at mRNA level using RNA-seq analysis, and further found this fusion gene might result in the truncation of FGFR1.

Conclusions: Collectively, we characterized the prevalence of FGFR1/2 genetic alterations in Chinese breast cancer, and identified 5 of novel FGFR1 fusion genes. The potential roles for novel FGFR1 fusion genes in regulating breast cancer cellular biology and in affecting the efficacy of endocrine therapy have been under the investigation in our laboratory, and the result from which will help us better elucidate the molecular mechanism of FGFR1 in driving the resistance of endocrine therapy.

[A clinical study of diaphragmatic dysfunction in subjects with mechanical ventilation in sepsis]

Objective: To investigate the prevalence of diaphragmatic dysfunction in mechanical ventilated subjects with sepsis and the relationship between diaphragmatic dysfunction and clinical outcomes. Methods: Newly intubated patients with sepsis diagnosed according to "Sepsis-3" were enrolled from January 2017 to October 2017 in Intensive Care Unit (ICU) of Sir Run Run Shaw Hospital. Diaphragm thickness was recorded ultrasonographically at end-inspiration and end-expiration when the patients' spontaneous breathing recovered. The diaphragmatic thickening fraction (DTF) was calculated as the percentage from the following formula: (Thickness at end-inspiration-Thickness at end-expiration) / Thickness at end-expiration. The subjects were stratified into a diaphragmatic dysfunction group and a non-diaphragmatic dysfunction group based on whether DTF was < 20%. Results: Fifty-three subjects were included, and the prevalence of diaphragmatic dysfunction was 41.5%(22/53). The diaphragm thickness at end-expiration of the 2 groups were similar(t=1.328, P>0.05). A significant difference of diaphragm thickness at end-inpiration was observed between the 2 groups[(2.2±0.4)mm vs. (2.8±0.8)mm, t=3.677, P<0.05]. Ventilation time after inclusion [(10±8)d vs. (6±5)d, t=2.340, P<0.05], mechanical ventilation durations [(15±8)d vs. (11±6)d, t=2.201, P<0.05] and ICU length of stay [(18±8)d vs. (14±7)d, t=2.039, P<0.05]were all significantly longer in the diaphragmatic dysfunction group than in the non-diaphragmatic dysfunction group. There was no significant difference in the mortality between these 2 groups(χ(2)=0.366, P>0.05). Conclusions: Diaphragmatic dysfunction was common in patients with sepsis treated by mechanical ventilation and was the consequence of contractile force damages. Subjects with such diaphragmatic dysfunction showed longer mechanical ventilation durations and ICU stays.

MicroRNA-433 inhibits migration and invasion of ovarian cancer cells via targeting Notch1

We aimed to determine the effects of miR-433 on the malignant behaviors of ovarian cancer cells, as well as to elucidate the possible mechanisms of ovarian cancer development. A total of 9 ovarian cancer tissues and 9 matched normal ovary tissues were obtained, and the expression levels of miR-433 and Notch1 were then determined by real-time PCR. Human ovarian cancer cell lines SKOV3 and OVCAR3 were transfected with miR-433 mimics, negative miR-control and Notch1 siRNA. The expression of Notch1 protein in transfected cells was determined by western blot. In addition, the proliferation, migration and invasion of SKOV3 and OVCAR3 cells in vitro were then evaluated using Cell Counting Kit 8, wound healing assay and Transwell invasion assay, respectively. Besides, bioinformatics methods and luciferace reporter assay were performed to confirm whether Notch1 was a direct target of miR-433. The expression of miR-433 was markedly down-regulated while Notch1 expression was significantly up-regulated in ovarian cancer tissues compared with matched normal ovary tissues. Overexpression of miR-433 significantly inhibited the migration and invasion of ovarian cancer cells, but had not significant effects on cell proliferation. In addition, Notch1 was a direct target of miR-433. Besides, down-regulation of Notch1 inhibited the invasion of ovarian cancer cells. Our findings indicate that miR-433 may inhibit cell migration and invasion in the development of ovarian cancer via down-regulation of Notch1. Notch1 may serve as a potential target in cancer therapy.

Search for doubly charged scalar bosons decaying into same-sign W boson pairs with the ATLAS detector

A search for doubly charged scalar bosons decaying into W boson pairs is presented. It uses a data sample from proton-proton collisions corresponding to an integrated luminosity of 36.1 fb - 1 collected by the ATLAS detector at the LHC at a centre-of-mass energy of 13 TeV in 2015 and 2016. This search is guided by a model that includes an extension of the Higgs sector through a scalar triplet, leading to a rich phenomenology that includes doubly charged scalar bosons H ± ± . Those bosons are produced in pairs in proton-proton collisions and decay predominantly into electroweak gauge bosons H ± ± → W ± W ± . Experimental signatures with several leptons, missing transverse energy and jets are explored. No significant deviations from the Standard Model predictions are found. The parameter space of the benchmark model is excluded at 95% confidence level for H ± ± bosons with masses between 200 and 220 GeV.

Correlations of ultrasonic features with severity of liver cancer and p16 expression in patients with liver cancer

This paper analyzes the correlations of ultrasonic features with clinical-pathological manifestations and p16 expression in patients with liver cancer. A total of 84 patients with primary liver cancer were randomly enrolled. The characteristics of liver cancer were examined via conventional ultrasound and contrast-enhanced ultrasound (CEUS) before operation. The p16 protein expressions in liver cancer and para-carcinoma tissues were detected via immunohistochemistry (IHC), and the correlations of p16 positive expression with ultrasound parameters were also analyzed. It was manifested via ultrasound that 6.4% (3/47) of stage I-II liver cancer showed the equal-echo change in portal phase, while others faded and showed the equal-echo change with 32.4% (12/37) of stage III-IV liver cancer. There were no statistically significant differences in ultrasonic features of patients in stage I-II and stage III-IV in the arterial and delayed phases (p>0.05). The positive expression rate of p16 protein in para-carcinoma tissues was 85.71% (72/84) which was significantly higher than that in liver cancer tissues (30.95%, 26/84) (p<0.05). Maximum intensity (IMAX), time to peak (TTP) and mean transit time (mTT) had no statistically significant differences between the p16 positive and negative groups, but there were statistically significant differences in rising slope (RS) and washout time (WT) (p<0.05). Correlation analyses revealed that the positive expression of p16 had no significant correlations with IMAX, mTT and TTP (p>0.05), but it positively correlated with RS (correlation coefficient r=0.377, p<0.05) and negatively correlated with WT (r=-0.410, p<0.05). Conventional ultrasound and CEUS can evaluate the expression of p16 protein in liver cancer repeatedly and non-invasively. The evaluations therefore have great significance in clinical treatment of liver cancer.
