Abstract
Enhancement of light extraction efficiency (LEE) of AlGaN-based deep-ultraviolet (DUV) light emitting diodes (LEDs) has been attempted by adopting Ag-nanodots/Al reflective electrodes on a highly transparent complex p-type layer. By thinning the p-GaN to several nm, highly DUV transparent p-type layer is achieved, making it meaningful for the application of reflective electrodes composed of Ag-nanodots and Al film to allow most light emitted upward to be reflected back to the sapphire side. By this approach, the maximum light output power and external quantum efficiency of the DUV-LEDs with optimized Ag nanodots/Al electrodes are severally increased by 52% and 58%, respectively, compared to those with traditional Ni/Au electrodes when the current is below 200 mA.

Abstract
OBJECTIVE The incidence and death rate of lung cancer has been rising year by year. Non-small cell lung cancer (NSCLC) seriously affects people's health and quality of life. This study was designed to explore the functional role of long-chain non-coding RNA (LncRNA) MIR503HG in the development of NSCLC. PATIENTS AND METHODS The quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) assay was conducted to access the expression level of MIR503HG in NSCLC cell lines and tissues. The Cell Counting Kit-8 (CCK-8) assay, colony formation assay, and flow cytometric analysis were performed to assess the ability of MIR503HG in regulating cell proliferation and apoptosis in NSCLC. Subsequently, Western blotting was used to detect the expression level of Wnt1 in NSCLC. Besides, in vivo tumorigenesis assay was performed in nude mice to examine the ability of MIR503HG in tumor formation. RESULTS MIR503HG was downregulated in NSCLC. CCK-8 assay and colony formation assay revealed that MIR503HG negatively regulated cell proliferation in NSLCL progression. In addition, MIR503HG promoted cell apoptosis and suppressed cell cycle progression in NSCLC in vitro. MIR503HG inhibited tumor formation in nude mice bearing NSCLC in vivo. MIR503HG downregulated Wnt1 expression in NSCLC. CONCLUSIONS Lon non-coding RNA MIR503HG was downregulated in NSCLC. The over-expression of MIR503HG suppressed cell proliferation and promoted cell apoptosis in vitro and repressed tumorigenesis in vivo. MIR503HG suppressed NSCLC progression via negatively regulating Wnt1 expression.

Abstract
OBJECTIVE The aim of this study was to explore the effect of long non-coding ribonucleic acid (lncRNA) ROR on myocardial fibrosis in rats with viral myocarditis by regulating c-myc expression. MATERIALS AND METHODS A total of 120 healthy male rats were randomly divided into three groups, including: blank control group (group N, healthy rats, n=40), model control group (group M, viral myocarditis, n=40), and group P (lncRNA ROR + viral myocarditis, n=40). At 5, 10, and 15 d after modeling, the rats were sacrificed. Meanwhile, the left ventricular mass index (LVMI), the left ventricular weight/tibial length (LVW/TL) and the heart mass index (HMI) were measured, respectively. The myocardial tissues of rats were observed via staining. The protein and mRNA expressions of the transforming growth factor-β (TGF-β) and c-myc in myocardial tissues were detected via Western blotting and quantitative Real Time-Polymerase Chain Reaction (qRT-PCR), respectively. Moreover, the level of the serum interleukin-6 (IL-6) was detected via enzyme-linked immunosorbent assay (ELISA). RESULTS Compared with group N, HMI, LVMI, and LVW/TL in group M significantly increased at each time point (p<0.01). Meanwhile, they were remarkably elevated at each time point in group P when compared with those in group M (p<0.01). According to the results of hematoxylin-eosin staining (HE) staining, the myocardial fibers were normal and orderly arranged in group N. Meanwhile, no inflammatory cells were observed in group N. In group M, the proliferation of a large number of inflammatory cells was observed, and the myocardial cells were disorderly arranged and became enlarged. In group P, the myocardial fibrosis was significantly severer than that of the other two groups (p<0.05). The results of the Masson staining revealed that there was significantly less accumulation of collagen fibers in myocardium in group N. There was a little accumulation of collagen fibers in the myocardium and fibrosis declined in group M. The myocardial fibrosis in group P remarkably increased when compared with group M (p<0.05). According to the results of the Western blotting, the protein expressions of c-myc and TGF-β were significantly up-regulated in group P, compared with those in group M and N (p<0.05). However, they were remarkably higher in group M than in group N (p<0.05). QRT-PCR showed that the relative messenger ribonucleic acid (mRNA) expressions of c-myc and TGF-β were remarkably up-regulated in group P when compared with those in group M and N, showing statistically significant differences (p<0.05). Moreover, they were significantly higher in group M than those in group N (p<0.05). Besides, the expression level of serum IL-6 remained highest in group P (p<0.01). CONCLUSIONS LncRNA ROR up-regulates the expression of c-myc and increases the level of serum IL-6, thereby facilitating the proliferation and differentiation of cardiac fibroblasts.

Abstract
Abstract
Background
Prediction of death is the philosopher's stone of arrhythmology. The electrophysiology has proven to be an important tool to predict the risk of death. Periodic repolarization dynamics (PRD) is a novel electrocardiographic marker that indicates the sympathetic effect on repolarization. PRD qualifies the low-frequency oscillations of cardiac repolarization instability using high-resolution 12 channel 24-h Holter recording. Several studies showed that PRD was an independent predictor of all-cause mortality and cardiac mortality. However, the prediction value of PRD has not been established.
Purpose
To evaluate the prediction value of PRD as an approach of risk stratification that selects patients at a higher risk of death.
Methods
We conducted electronic searches of MEDLINE (PubMed), Embase, Cochrane Register of Controlled Trials (CENTRAL), Science Citation Index Expanded, WHO International Clinical Trials Registry platform (ICTRP) and ClinicalTrials.gov from inception to January 9th, 2020. We also screened for relevant abstracts from conferences including ACC Annual Scientific Sessions, ESC Congress and Annual Congress of the EHRA for the last five years (2014–2019). The primary outcome was all-cause mortality and secondary outcome was cardiac mortality. We included study with large sample size while more than one study were found based on the same originated population. We extracted data from included studies and reported pooled outcomes as hazard ratios (HRs) with 95% confidential intervals (CI) for time-to-event outcomes using DerSimonian-Laird random-effects model. We did statistical analyses using Stata version 12.0 and R version 3.6.1.
Results
5 studies including 6758 patients met all selection criteria for our meta-analysis. Follow-up period ranged from 20.4 to 75.1 months. Among 5 studies, 3 studies considered PRD as dichotomous variable and the cut-off value was 5.75 deg2, while 2 studies considered PRD as continuous variable and coefficient was expressed in standardized units (increase per standard deviation). We did subgroup analysis according to the type of variable because of heterogeneity. There was a significant higher risk of all-cause mortality in PRD ≥5.75 deg2 patients compared with PRD <5.75 deg2 patients (HR 2.37, 95% CI 1.77–3.17). As for continuous variable, increased PRD was a predictor for all-cause death (HR 1.28, 95% CI 1.14–1.42) (Figure). The cardiac mortality was significantly increased in patients with PRD ≥5.75 deg2 vs PRD <5.75 deg2 (HR 3.06, 95% CI 1.66–5.65). Increased PRD was associated with cardiac mortality in continuous variable subgroup (HR 1.34, 95% CI 1.21–1.48) (Figure).
Conclusion
Our findings suggest PRD is a significant predictor of all-cause mortality and cardiac mortality. PRD provides new additional electrophysiological indicator for risk stratification until further investigations are available.

Abstract
Abstract
Background
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease characterized by fibrofatty replacement of the myocardium and ventricular arrhythmias. Biventricular (BiV) involvement in ARVC may lead to heart failure.
Purpose
This study aimed to investigate the role of novel plasma biomarkers soluble (s)ST2, Galectin-3 (Gal-3) and GDF-15 in predicting BiV involvement and adverse outcomes in ARVC patients.
Methods
ARVC patients from two independent cohorts were studied. 108 patients were included from the discovery cohort and 47 patients were included from a second validation cohort. All patients had a definite ARVC diagnosis at time of blood withdrawal. sST2, Gal-3 and GDF-15 were independently correlated with NT-proBNP, left ventricular (LV) ejection fraction, late gadolinium enhancement by cardiac magnetic resonance (CMR) imaging and clinical outcome.
Results
ARVC patients with LV involvement had higher levels of sST2 and GDF-15 as compared to controls and patients with isolated right ventricular involvement. sST2 and GDF-15 significantly correlated to late gadolinium enhancement on CMR and also correlated to adverse heart failure outcomes. Gal-3 was elevated in ARVC patients with and without LV involvement as compared to controls. The combined use of the three biomarkers (NT-proBNP, sST2 and GDF-15) showed the best performance in predicting LV involvement in both the discovery and the validation cohort. Plasma drawn from coronary arteries and coronary sinus showed a transmyocardial elevation of sST2.
Conclusion
Our study shows that sST2 and GDF-15 may predict BiV involvement and the combined use of NT-proBNP, sST2 and GDF-15 shows the best prediction of LV involvement in ARVC. Transmyocardial elevation of sST2 suggests that this biomarker is produced by myocardial tissue in ARVC.

Abstract
OBJECTIVE The aim of this study was to explore the correlations of changes in inflammatory factors, glucose and lipid metabolism indicators and adiponectin with alterations in intestinal flora in rats with coronary heart disease. MATERIALS AND METHODS A total of 30 male specific pathogen-free rats were randomly assigned into two groups, including: blank group (n=15) and coronary heart disease group (n=15). The rats in the coronary heart disease group were given high-fat diets and pituitrin to establish the model of coronary heart disease. Meanwhile, rats in the blank group were administered with an equal volume of double-distilled water. The alterations in the intestinal flora of rats were detected in the two groups, respectively. In addition, the changes in the levels of inflammatory factors, glucose and lipid metabolism indicators, adiponectin, creatine kinase (CK) and its isoenzyme, as well as troponin, were also examined. RESULTS Statistically, significant differences in the levels of glucose and lipid metabolism indicators low-density lipoprotein (LDL) (p=0.040), total cholesterol (TC) (p=0.039), high-density lipoprotein (HDL) (p=0.044), triglyceride (TG) (p=0.000) and blood glucose (p=0.046) were observed between the rats in the coronary heart disease group and blank group. The content of all the glucose and lipid metabolism indicators (except HDL) in coronary heart disease group was significantly higher than the blank group (p<0.05). The rats in the coronary heart disease group had evidently higher levels of CK (p=0.000) and its isoenzyme (p=0.019), as well as troponin (p=0.021), than those in the blank group. The level of serum adiponectin in rats in coronary heart disease group was distinctly lower than that in the blank group, showing statistically significant differences (p<0.05). Besides, the levels of the inflammatory factors interleukin (IL)-2 (p=0.011), transforming growth factor (TGF)-β (p=0.048), tumor necrosis factor-α (TNF-α) (p=0.025) and IL-6 (p=0.038) in rats in the coronary heart disease group were dramatically higher than those in blank group. Rats in coronary heart disease group had remarkably more Actinobacteria, Desulfovibrio, Aristipus and Escherichia coli in the intestine. Meanwhile, the abundance of Flavobacterium, Burkhofer and some probiotics increased significantly in the intestine of rats in blank group (p<0.05). The changes in the abundance of Actinobacteria, Desulfovibrio, Aristipus and Escherichia coli in the intestine of rats were probably correlated with increased levels of glucose and lipid metabolism indicators, inflammatory factors and adiponectin in coronary heart disease group. Moreover, the abundance of intestinal probiotics such as Bifidobacterium and Lactobacillus in rats in coronary heart disease group was notably lower than that in blank group (p<0.05). The decline in the abundance of such intestinal probiotics as Bifidobacterium and Lactobacillus was correlated with the changes in the levels of glucose and lipid metabolism indicators, inflammatory factors and adiponectin. In addition, decreased levels of probiotics weakened normal physiological functions of the intestine and promoted disease progression. CONCLUSIONS Inflammatory factors, glucose and lipid metabolism indicators and adiponectin have evident changes in rats with coronary heart disease, which may be correlated with the alterations in the intestinal flora.

Abstract
Tibial dyschondroplasia (TD) is an intractable avian cartilage disease in which proximal growth plates of tibia lack blood vessels and contain nonviable cells, and it leads to the inflammatory response. Prostaglandins (PGs) genes have not been studied yet in TD chicken, and they might play role in skeletal metabolism, therefore we planned to explore the role of recombinant glutathione-S-transferase A3 (rGSTA3) protein and PG-related genes. In this study, qRT-PCR, enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) analysis were used to identify the expression patterns of eight PG-related genes in the tibial growth plate of broiler chicken. The results showed that the expression of PG-related genes glutathione-S-transferase A3 (GSTA3), cyclooxygenase 2 (COX-2), prostaglandin D2 synthase (PTGDS), prostaglandin E synthase (PTGES), prostaglandin E2 receptor (PTGER) 3, PTGER4, prostaglandin reductase 1 (PTGR1) and hematopoietic prostaglandin D synthases (HPGDS) expression were identified and could significantly respond to thiram-induced TD chicken. Interestingly, the expression of rate-limiting enzyme COX-2 and PGE2 were induced after the treatment of rGSTA3 protein. These findings demonstrated that the occurrence of TD is closely related to the inhibition of PGs. Moreover, rGSTA3 protein participated in the recovery of TD by strengthening the expression of PG-related genes.

Abstract
OBJECTIVE Neuroblastoma is a common malignancy in children. Despite the occurrence of diverse therapies in recent years, the survival rate of patients with high-risk NB is still unpredictable due to the high metastatic potential and poor prognosis. Therefore, it is urgent to study the molecular mechanism of NB metastasis. SNHG1 has been reported to be closely related to the development, metastasis, and prognosis of many cancers. The purpose of this study was to clarify the molecular mechanism of the role of SNHG1 in NB tumors. PATIENTS AND METHODS The expression levels of SNHG1, miR-338-3p, and PLK4 were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. The functional targets between miR-338-3p and SNHG1 or PLK4 were predicted by online software Diana tools and observed by Luciferase reporter assay and RIP assay. Cell proliferation was measured by MTT assay. Cell migration and invasion were operated through flow cytometry. The expression of p-AKT was quantified by Western blot. Xenograft tumor model was established to confirm the biological role of SNHG1 in NB in vivo. RESULTS The expression levels of SNHG1 and PLK4 were increased in NB tissues and cells, and miR-338-3p expression was on the contrary. PLK4 was verified as a direct target of miR-338-3p and miR-338-3p could specially bind to SNHG1. The negative effect of SNHG1 down-regulation on cell proliferation, migration, and invasion could be rescued by miR-338-3p inhibition. The suppression of miR-338-3p mimics on cell proliferation, migration, and invasion could be reversed by PLK4 overexpression. In addition, SNHG1 knockdown weakened the volume and weight of tumor in vivo. CONCLUSIONS SNHG1 conduced to tumorigenesis and mechanism by upregulating PLK4 and by acting as miR-338-3p sponge in neuroblastoma.

Abstract
OBJECTIVE The X-linked inhibitor of apoptosis protein (XIAP) is associated with the development of various tumors. The abnormal miR-142 expression is associated with the onset of lung cancer. Bioinformatics analysis revealed a targeted relationship between miR-142 and XIAP. This report investigated whether miR-142 plays a role in regulating XIAP expression and affecting the biological processes of lung cancer cells. PATIENTS AND METHODS The tumor tissues of lung cancer patients were collected, and the adjacent tissues were used as controls. The dual luciferase reporter gene assay validated the targeted regulation between miR-142 and XIAP. Using BEAS-2B cells as control, qRT-PCR was used to detect the expression of miR-142 and XIAP in lung cancer cells A549 and H1650. Lung cancer H1650 cells were cultured and divided into miR-NC group and miR-142 mimic group followed by an analysis of cell proliferation by EdU staining. RESULTS Compared with those in adjacent tissues, miR-142 expression was significantly decreased and XIAP expression was increased in lung cancer tissues. The Dual-Luciferase Reporter Assay confirmed a targeted regulation relationship between miR-142 and XIAP. Compared with BEAS-2B cells, miR-142 expression in lung cancer A549 and H1650 cells was significantly decreased, and XIAP expression was significantly increased. Transfection of miR-142 mimic significantly inhibited the expression of XIAP in H1650 cells, promoted apoptosis and inhibited cell proliferation. CONCLUSIONS Decreased miR-142 expression and increased XIAP expression is associated with the onset of lung cancer. MiR-142 can inhibit lung cancer cell proliferation and induce apoptosis through inhibition of XIAP expression.

Abstract
Objective: To understand the effect of organ donation surgery on the mental health of nurses in operating room, and to explore the intervention effects. Methods: From Jan.2015 to Dec. 2018, 60 operating room nurses in our hospital participating in organ donation surgery were selected for investigation of mental health, and were intervened by group psychological training, positive psychological intervention, improving shift arrangement system and financial support. The SCL-90 scale and DAP-R scale were used to evaluate before and after intervention. Results: The mean scores of somatization, interpersonal sensitivity, depression, anxiety, terror, paranoia and psychoticism in SCL-90 scale of 60 operating room nurses were (2.07±0.63) , (2.07±0.69) , (1.88±0.62) , (1.71±0.57) , (1.78±0.67) , (1.71±0.68) , (1.73±0.60) before intervention respectively, which were significantly higher than the Chinese norm (P<0.01) and those[ (1.64±0.60) , (1.46±0.57) , (1.53±0.62) , (1.48±0.60) , (1.28±0.50) , (1.45±0.56) , (1.43±0.52) ] after intervention were lower than before (P<0.01) . Before and after the intervention, the scores of DAP-R scale tended to be death fear dimension and acceptance dimension, the proportion of the death fear dimension was 16.7% (10/60) and 6.7% (4/60) , respectively, and the approaching acceptance dimension was 83.3% (50/60) and 93.3% (56/60) . The proportion of the nurses with scores of SCL-90 scale ≥160 after the intervention was significantly lower than that before the intervention (χ(2)=5.82, P<0.05) . Conclusion: The mental health of nurses in the operating room participating in organ donation surgery is lower; After intervention, the investigated nurses present improved mental health and positively emotional attitude towards death.
