Abstract
Global ecosystem services (ESs) are experiencing a significant decline, necessitating the development of robust environmental governance policies. To address the lack of integrated planning with heavy industry as the research object and a lack of knowledge of ES trade-offs and synergies in China's ecological and environmental governance. In this study, the spatial and temporal variations of four ESs (water yield (WY), soil conservation (SC), carbon storage (CS), and habitat quality (HQ)) were determined in the study area of Liaoning Province. Explore the mechanisms that shape ecosystem service trade-offs and synergies and the factors that influence them. Spearman's correlation and difference analyses were proposed to determine the spatial and temporal distributions of trade-offs and synergistic relationships among ESs. In addition, we constructed a multiscale geo-weighted regression (MGWR) model to investigate driver spatial heterogeneity affecting trade-offs and synergies. The results revealed that (1) In the study area, ESs were on the rise in Liaoning Province. (2) Temporally, ESs were overwhelmingly dominated by synergies; at the spatial scale, ESs were dominated by trade-offs of varying degrees, with the area of synergy between WY and SC being the highest. (3) ESs demonstrated spatial heterogeneity in intensity and were more impacted by natural factors such as vegetation cover, elevation, and precipitation than by characteristics related to human activity. This study helps improve understanding of the interactions and dependencies among ESs and can provide a reference for ecological governance and improvements in Liaoning Province.

Abstract
INTRODUCTION Approximately 7.2% of children in the world suffer from attention-deficit/hyperactivity disorder (ADHD). Due to the availability of the osmotic-release oral-system methylphenidate, ADHD currently has a remission rate of up to 30.72%. Nevertheless, it has been reported that patients with ADHD tend to exhibit vitamin A and vitamin D deficiency, which may aggravate the symptoms of ADHD. This study aims to determine the effect of vitamin A and vitamin D supplementation as adjunctive therapy to methylphenidate on the symptoms of ADHD. METHODS AND ANALYSIS This is a parallel, prospective, interventional multicentric study. Patients will be enrolled from the southern, central and northern parts of China. A target of 504 patients will be followed for 8 weeks. They will be allocated into three groups (vitamin AD, vitamin D and placebo) and administered the interventions accordingly. Data on changes in the symptoms of ADHD as well as changes in the serum concentrations of vitamin A and vitamin D will be recorded. Both responders and nonresponders based on the sociodemographic and clinical data will also be described to mitigate selection bias. ETHICS AND DISSEMINATION This study is performed in accordance with the Declaration of Helsinki and was approved by the Institutional Review Board of Children's Hospital of Chongqing Medical University, China (approval number: (2019) IRB (STUDY) number 262). The results of the trial will be reported in peer-reviewed scientific journals and academic conferences regardless of the outcomes. TRIAL REGISTRATION NUMBER NCT04284059.

Abstract
Objective: To investigate the value of low-dose multi-slice CT (MSCT) chest scan in the diagnosis of coal workers' pneumoconiosis. Methods: A total of 90 patients with a confirmed diagnosis of coal workers' pneumoconiosis were enrolled, and under the conditions of fixed tube voltage, pitch, and slice thickness, they underwent CT scan with a normal dose (150 mA) and a low dose (30-50 mA). The quality of images obtained from two scans was compared, and the imaging findings, opacity profusion, stage, and radiation doses were also compared. Results: Compared with the normal-dose scan, low-dose scan increased the image noise, and the images obtained from scans with doses of 30, 40, and 50 mA did not show significant reductions in signal-to-noise ratio or contrast-to-noise ratio (P>0.05). There was no significant difference in the percentage of image quality between low-dose and normal-dose scans (P>0.05). There were no significant differences in the percentage of various imaging findings, opacity profusion, or percentage of different stages between low-dose (30, 40, and 50 mA) and normal-dose (150 mA) scans (P>0.05). Conclusion: There are no significant differences between low-dose MSCT chest scan and normal-dose CT in image quality, imaging findings of coal workers' pneumoconiosis, opacity profusion, and stage. Meanwhile, low-dose MSCT chest scan greatly reduces the radiation dose and can be used to assist the diagnosis and follow-up reexamination of coal workers' pneumoconiosis and cover the shortage of high-kilovoltage chest X-ray.

Abstract
OBJECTIVE To investigate the high-risk factors for the quality of general movements (GMs), which has a predictive value for brain dysfunction in infants. METHODS A total of 618 infants in the stage of writhing movements and 539 infants in the stage of fidgety movements were selected separately for the evaluation of GMs. The high-risk factors for the quality of GMs in infants were analyzed by ANOVA, chi-square test, and multivariate logistic regression. RESULTS Multivariate logistic regression analysis showed that the factors significantly associated with the quality of GMs in the stage of writhing movements were gestational age (OR=0.762, P<0.001), birth weight (OR=0.264, P<0.001), severe asphyxia (OR=2.445, P=0.012), and intrauterine distress (OR=4.865, P<0.001); the factors significantly associated with the quality of GMs in the stage of fidget movements were gestational age (OR=0.786, P=0.003), birth weight (OR=0.217, P<0.001), severe asphyxia (OR=3.765, P=0.001), and hyperbilirubinemia (OR=2.640, P=0.028). CONCLUSIONS Low gestational age, low birth weight, severe asphyxia, hyperbilirubinemia and intrauterine distress are high-risk factors for abnormal GMs in infants, and early screening and intervention should be performed to reduce the incidence of abnormal nervous system sequelae.

Abstract
Reactive oxygen species such as superoxide are implicated in cardiac hypertrophy, but their contribution to the cardiac complications of insulin resistance is unresolved. We tested the hypothesis that the antioxidant tempol attenuates cardiac hypertrophy in insulin-resistant mice. Mice with cardiac GLUT4 deletion (GLUT4-knockout), superimposed on global GLUT4 suppression (GLUT4-knockdown) were administered tempol for 4 weeks. Age-matched GLUT4-knockdown littermates were used as controls (14 mice/group). GLUT4-knockout mice exhibited marked cardiac hypertrophy: heart to body weight ratio was increased 61+/-7% and expression of the hypertrophic genes beta-myosin heavy chain and B-type natriuretic peptide (BNP) were elevated 5.5+/-0.7- and 6.2+/-1.5-fold relative to control, respectively. Pro-fibrotic pro-collagen III expression was also higher (3.8+/-0.7-fold) in the GLUT4-knockout myocardium (all p<0.001). Both gp91(phox) and Nox1 subunits of NADPH oxidase were also upregulated, 4.9+/-1.2- and 9.3+/-2.8-fold (both p<0.01). Tempol treatment significantly attenuated all of these abnormalities in GLUT4-knockout mice. Heart to body weight ratio was decreased, as was fold expression of beta-myosin heavy chain (to 3.8+/-0.8), BNP (to 2.5+/-0.5), pro-collagen III (to 1.9+/-0.4), gp91(phox) (to 0.9+/-0.3) and Nox1 (to 2.3+/-0.1, all p<0.05 versus untreated GLUT4-knockout mice). In addition, tempol upregulated ventricular expression of both thioredoxin-2 (confirming an antioxidant action) and glycogen synthase kinase-3beta (GSK-3beta). Tempol did not elicit any other significant changes in control mice. Cardiac superoxide generation, however, was not altered by GLUT4-knockout or tempol. In conclusion, tempol treatment reduced morphological and molecular evidence of cardiac hypertrophy in the GLUT4-knockout insulin-resistant mouse in vivo, even at doses insufficient to lower cardiac superoxide. Parallel reductions in pro-collagen III and NADPH oxidase have important implications for our understanding of the molecular basis of cardiac hypertrophy in the setting of insulin resistance. Antioxidants may offer new alternatives in this disorder.
