Abstract
Background:Growing evidences have demonstrated that autophagy is a powerful regulators in the pathogenesis of fibrosis and autoimmune diseases. Autophagy abnormalities in SSc involve abnormal autophagy-related protein and autophagy-related gene polymorphism[1-2], however there is a few reports on the expression and clinical significance of autophagy-related genes.Objectives:To investigate the expression and clinical significance of autophagy-related genes LC-3 mRNA, Becline-1 mRNA, Agt-3 mRNA, Agt-5 mRNA, Agt-12 mRNA and Agt-16L1 mRNA in peripheral blood mononuclear cells (PBMC) of systemic sclerosis (SSc).Methods:51 cases of SSc and 60 cases of normal control were received from the Affiliated Hospital of North Sichuan Medical College, and autophagy-related genes were detected by RT-PCR. SPSS19.0 statistical software was used to compare the expression of autophagy-related genes between groups and analyze the relationship between autophagy-related genes and clinical data, P<0.05 was considered statistically significantResults:LC-3, Becline-1, and Agt-3 were highly expressed in SSc compared with normal control [LC-3: 0.78(0.60) ×10-3 vs. 0.52(0.54) ×10-3; Beclin-1: 6.68(3.56)×10-3 vs. 5.22(3.54)×10-3; Agt-3: 17.58(12.33)×10-3 vs. 11.00(4.56)×10-3, P<0.05], however Agt-5, Agt-12 and Agt-16L1 of autophagy-related genes were not statistically significant [AGT-5: 6.67(3.58) ×10-3 vs. 6.67(2.64) ×10-3; AGT-12: 8.64(5.56)×10-3 vs. 8.57(4.66)×10-3; Agt-16L1: 2.69(2.19)×10-3 vs. 2.52(2.26)×10-3] (Figure 1). Beclin-1 and Agt-5 high expressed in SSc with the positive of anti-SSA/Ro antibody. LC-3 was positively correlated with Age(r=0.662) and ESR(r=0.355) (all P<0.05).Conclusion:Autophagy-related genes were increased in PBMC of SSc, and were correlated with Age, ESR and autoantibody, suggested that autophagy is a key feature in the pathogenesis of systemic sclerosis.Figure 1.The relative expression of autophagy-related genesReferences:[1]LIU C, ZHOU X, LU J, et al.

Abstract
The results demonstrated that pancreatic ductal carcinoma (PDAC) of the body/tail was associated with more transcriptional and genomic changes, and correlated with worse prognosis, than PDAC of the pancreatic head. The different mutation types and gene expression of tumour locations provide deep insight into the carcinogenesis or metastasis of PDAC, and suggest different early diagnostic and therapeutic strategies.

Abstract
OBJECTIVE To investigate the mechanism by which amentoflavone inhibits polarization of THP-1-derived foam cells to M1 phenotype. OBJECTIVE Human monocyte cell line THP-1 was stimulated to differentiate into M1-type macrophages using phorbol 12-myrislate13-acetate (PMA) combined with lipopolysaccharide (LPS) and recombinant human interferon-γ (rhlFN-γ). M1 polarization of THP-1-derived macrophages was confirmed by observing morphological changes of the cells and detecting the mRNA expression of L-6 and TNF-α with RT-qPCR. THP-1-derived foam cells treated with 5 or 10 μmol/L amentoflavone for 24 h were examined for cytokines using ELISA. The mRNA and protein expressions of IL-6, IL-10, TNF-α, TGF-β, PPAR-α/γ, Arg-1 and Fizz1 in the cells were detected using RT-qPCR and Western blotting. OBJECTIVE Amentoflavone prevented induced M1 polarization of THP-1 cells. Amentoflavone down-regulated the mRNA expressions of IL-6 and TNF-α, up-regulated mRNA expressions of IL-8 and TGF-β mRNA (P < 0.05), and increased the protein expressions of PPAR-α/γ, Arg-1 and Fizz1. Molecular docking simulation showed that amentoflavone could bind to the surface of PPARα/γ. OBJECTIVE Amentoflavone can inhibit the differentiation of macrophages into M1 type by activating PPAR-α/γ and restoring the expressions of the gene Arg-1 and Fizz1.

Abstract
OBJECTIVE Dysfunction of vascular endothelial cells was associated with diverse human diseases, including cardiovascular disease. Long noncoding RNAs (LncRNAs) were involved in the regulation of cell injury. We aimed to investigate the role of lncRNA testis-specific transcript, Y-linked 15 (TTTY15) in hypoxia-induced cell injury in human umbilical vein endothelial cells (HUVECs). MATERIALS AND METHODS Cell counting kit-8 (CCK8) assay was used to check cell viability. Lactate dehydrogenase (LDH) assay kit and flow cytometry were utilized to evaluate the leakage rate of LDH and cell apoptosis, respectively. The protein levels of Cyclin D1 and B-cell lymphoma-2-Associated X (Bax) in hypoxia-induced HUVECs were measured by Western blot. Quantitative Real-time polymerase chain reaction (qRT-PCR) was conducted to detect the expression levels of TTTY15 and miR-186-5p in hypoxia-induced HUVECs. The starBase was utilized to predict the binding sites between TTTY15 and miR-186-5p and the dual-luciferase reporter assay was performed to verify the interaction. RESULTS Hypoxia inhibited cell viability and promoted the release of LDH and cell apoptosis in HUVECs. Besides, hypoxia significantly decreased the protein level of Cyclin D1 and increased the protein level of Bax in HUVECs. In addition, the expression level of TTTY15 was obviously upregulated in hypoxia-induced HUVECs, opposite to the level of miR-186-5p. Meanwhile, knockdown of TTTY15 or upregulation of miR-186-5p mitigated hypoxia-induced cell injury in HUVECs. Further studies suggested that TTTY15 targeted miR-186-5p and regulated hypoxia-induced cell injury via interacting with miR-186-5p in HUVECs. CONCLUSIONS Downregulation of TTTY15 ameliorated hypoxia-induced cell injury by targeting miR-186-5p in HUVECs.

Abstract
Enolase 1 (ENO1) is an oxidative stress protein expressed in endothelial cells. This study aimed to investigate the correlation of ENO1 with prognosis, tumor stage, and levels of tumor-infiltrating immune cells in multiple cancers. ENO1 expression and its influence on tumor stage and clinical prognosis were analyzed by UCSC Xena browser, Gene Expression Profiling Interactive Analysis (GEPIA), The Cancer Genome Atlas (TCGA), and GTEx Portal. The ENO1 mutation analysis was performed by cBio Portal, and demonstrated ENO1 mutation (1.8%) did not impact on tumor prognosis. The relationship between ENO1 expression and tumor immunity was analyzed by Tumor Immune Estimation Resource (TIMER) and GEPIA. The potential functions of ENO1 in pathways were investigated by Gene Set Enrichment Analysis. ENO1 expression was significantly different in tumor and corresponding normal tissues. ENO1 expression in multiple tumor tissues correlated with prognosis and stage. ENO1 showed correlation with immune infiltrates including B cells, CD8+ and CD4+ T cells, macrophages, neutrophils, and dendritic cells, and tumor purity. ENO1 was proved to be involved in DNA replication, cell cycle, apoptosis, glycolysis process, and other processes. These findings indicate that ENO1 is a potential prognostic biomarker that correlates with cancer progression immune infiltration.

Abstract
OBJECTIVES To evaluate the feasibility of using deep-learning algorithms to classify as normal or abnormal sonographic images of the fetal brain obtained in standard axial planes. METHODS We included in the study images retrieved from a large hospital database from 10 251 normal and 2529 abnormal pregnancies. Abnormal cases were confirmed by neonatal ultrasound, follow-up examination or autopsy. After a series of pretraining data processing steps, 15 372 normal and 14 047 abnormal fetal brain images in standard axial planes were obtained. These were divided into training and test datasets (at case level rather than image level), at a ratio of approximately 8:2. The training data were used to train the algorithms for three purposes: performance of image segmentation along the fetal skull, classification of the image as normal or abnormal and localization of the lesion. The accuracy was then tested on the test datasets, with performance of segmentation being assessed using precision, recall and Dice's coefficient (DICE), calculated to measure the extent of overlap between human-labeled and machine-segmented regions. We assessed classification accuracy by calculating the sensitivity and specificity for abnormal images. Additionally, for 2491 abnormal images, we determined how well each lesion had been localized by overlaying heat maps created by an algorithm on the segmented ultrasound images; an expert judged these in terms of how satisfactory was the lesion localization by the algorithm, classifying this as having been done precisely, closely or irrelevantly. RESULTS Segmentation precision, recall and DICE were 97.9%, 90.9% and 94.1%, respectively. For classification, the overall accuracy was 96.3%. The sensitivity and specificity for identification of abnormal images were 96.9% and 95.9%, respectively, and the area under the receiver-operating-characteristics curve was 0.989 (95% CI, 0.986-0.991). The algorithms located lesions precisely in 61.6% (1535/2491) of the abnormal images, closely in 24.6% (614/2491) and irrelevantly in 13.7% (342/2491). CONCLUSIONS Deep-learning algorithms can be trained for segmentation and classification of normal and abnormal fetal brain ultrasound images in standard axial planes and can provide heat maps for lesion localization. This study lays the foundation for further research on the differential diagnosis of fetal intracranial abnormalities. Copyright © 2020 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
OBJECTIVE The mortality rate of ovarian cancer (OC) has always been the highest among all female reproductive system malignant tumors. Currently, miRNAs have been verified to participate in the tumorigenesis and prognosis of OC. However, the expression and function of miR-574-3p in OC have not been fully elucidated. PATIENTS AND METHODS The expression level of miR-574-3p in OC tissues and cells was detected using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). By transfection of miR-574-3p mimics or inhibitor, the expression of miR-574-3p in SW626 or A2780 cells was up-regulated or down-regulated, respectively. Cell counting kit-8 (CCK-8) and colony formation assays were used to measure the proliferation of transfected OC cells. Meanwhile, the transwell assay was applied to detect the migration and invasion abilities of OC cells. Furthermore, dual-luciferase reporter gene analysis and Western blot were utilized to explore the underlying downstream molecules for miR-574-3p in OC. RESULTS MiR-574-3p was lowly expressed in OC tissue samples when compared with para-tumor tissues. Meanwhile, the expression of miR-574-3p in OC-derived cells was significantly lower than normal control HOSE cells. The overexpression of miR-574-3p markedly reduced the proliferation, invasion, and migration of SW626 cells. However, the inhibition of miR-574-3p remarkably accelerated the growth and metastasis of A2780 cells. MMP3 was verified as a direct target for miR-574-3p in OC. In addition, miR-574-3p could reduce the protein expression of MMP3 by binding to its 3'-untranslated region (3'-UTR). CONCLUSIONS MiR-574-3p functioned as a tumor suppressor in OC, which might be served as a potential target for the diagnosis and therapy for OC.

Abstract
OBJECTIVE This study aimed to investigate the benefit of Bonebridge devices in patients with single-sided deafness. METHOD Five patients with single-sided deafness who were implanted with Bonebridge devices were recruited in a single-centre study. Participants' speech perception and horizontal sound localisation abilities were assessed at 6 and 12 months post-operatively. Speech intelligibility in noisy environments was measured in three different testing conditions (speech and noise presented from the front, speech and noise presented from the front and contralateral (normal ear) side separately, and speech presented from the ipsilateral (implanted Bonebridge) side and noise from the contralateral side). Sound localisation was evaluated in Bonebridge-aided and Bonebridge-unaided conditions at different stimuli levels (65, 70 and 75 dB SPL). RESULTS All participants showed a better capacity for speech intelligibility in quiet environments with the Bonebridge device. The speech recognition threshold with the Bonebridge device was significantly decreased at both short- and long-term follow up in the speech presented from the ipsilateral (implanted Bonebridge) side and noise from the contralateral side condition (p < 0.05). Additionally, participants maintained similar levels of sound localisation between the Bonebridge-aided and unaided conditions (p > 0.05). However, the accuracy of localisation showed some improvement at 70 dB SPL and 75 dB SPL post-operatively. CONCLUSION The Bonebridge device provides the benefit of improved speech perception performance in patients with single-sided deafness. Sound localisation abilities were neither improved nor worsened with Bonebridge implantation at the follow-up assessments.

Abstract
Approximately 89% of patients with Parkinson's disease (PD) suffer from dysarthria. Lee Silverman Voice Treatment (LSVT), a behavioral therapy, aims to improve speech and voice functions. The objective was to assess the effectiveness of LSVT compared with other/no speech interventions for dysarthria in patients with PD. Electronic databases, including PubMed, Embase and the Cochrane Library, were searched. The publication date of all included studies was before 6 March 2020. Only randomized controlled trials (RCTs) that evaluated the LSVT intervention compared with other/no speech intervention were considered. The data obtained from the included studies were described and the mean differences were calculated. Eight RCTs were included in this meta-analysis comparing LSVT with other/no speech interventions. In the comparison of LSVT versus no intervention, vocal intensity for sustained 'Ah' phonation, reading the 'Rainbow passage', monologue and describing a picture increased by 8.87, 4.34, 3.25 and 3.31 dB, respectively, after 1 month of therapy. Compared with the respiratory therapy group, the LSVT group also showed significant improvement in vocal intensity for sustained 'Ah' phonation, reading the 'Rainbow passage' and monologue immediately after treatment (13.39, 6.66 and 3.19 dB). Positive improvement still existed after 24 months. There was no difference in the therapeutic effect between face-to-face and online LSVT. The effectiveness of LSVT for dysarthria in patients with PD was verified in these trials. However, future RCTs with sufficient participants are essential to evaluate the effectiveness of LSVT for dysarthria.

Abstract
BACKGROUND Essential hypertension is one of the risk factors of cardiovascular and cerebrovascular diseases, which can cause target organ damage such as heart, brain and kidney, and has extremely high disability rate and death rate. With the development of economy and society, the prevalence rate of hypertension in China has increased rapidly from 9.8% in the 1980s to over 30% in the 21st century. According to the data published in "China Cardiovascular Disease Report 2018," China currently has 245 million hypertension patients. Comprehensive prevention and treatment of hypertension has become one of the major public health problems in China. The clinical practice and theoretical innovation of traditional Chinese medicine in the prevention and treatment of hypertension have been carried out for decades. Relevant literature points out that Tianma Gouteng Decoction combined with Qiju Dihuang Pill has ideal effect in the treatment of primary hypertension. However, most of the literatures are small sample studies, with uneven quality and clinical evidence, and lack of evidence-based medical evidence for clinical efficacy. Therefore, this study makes further meta-analysis of Tianma Gouteng Decoction combined with Qiju Dihuang Pill in the treatment of primary hypertension, with a view to providing evidence-based medical evidence for the treatment of primary hypertension. METHODS We will search 3 foreign electronic databases (Cochrane Library, Embase, PubMed) and 4 Chinese electronic databases (China National Knowledge Infrastructure, WangFang Database, Chinese Biomedical Literature Database, and Chinese Scientific Journal Database) to collect potential systematic reviews from their inceptions to February 2020. The language of publication is limited to Chinese or English. First, the quality of randomized controlled trials documents included in this study was evaluated by using the improved Jadad scoring scale. Then, the 2 researchers conducted the evaluation independently according to Cochrane bias risk tools. The evidence level of the results will be evaluated by using the recommended evaluation, development and evaluation grading of recommendations assessment, development, and evaluation method. Statistical analysis will be conducted using Revman 5.3. RESULTS The results of this study will be published in a peer-reviewed journal. CONCLUSIONS The conclusion of this study will provide evidence for the efficacy of Tianma Gouteng Decoction combined with Qiju Dihuang Pills in the treatment of primary hypertension due to the efficacy of western medicine alone in treating primary hypertension.

Abstract
BACKGROUND Liver fibrosis is a pathological change existing in most chronic liver diseases, which leads to abnormal changes in liver tissue structure and affects the normal physiological function of liver. Without effectively control, liver fibrosis can develop into cirrhosis and increase the risk of liver cancer. Salvianolic acid B (Sal B) is the main active component in the water-soluble extract from Salvia miltiorrhiza, which is a traditional Chinese medicine usually used for treating cardiovascular and liver diseases. It is reported that Sal B shown a good action against liver fibrosis via numerous signaling pathways, which indicate that Sal B is a potential candidate drug for the treatment of liver fibrosis. METHODS We searched the related researches from the following electronic databases: PubMed, EMBASE, Web of science, China National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), Wan fang Database for Chinese Technical Periodicals and VIP Database. All the databases were searched from inception to December 2019. No restriction of language, publication date, or publication status. PICO of this systematic review are shown as flowing: P, preclinical studies which evaluated the effects of Sal B on the animal models of liver fibrosis with controlled studies; I, received Sal B as only treat in any dose; C, received normal saline, distilled water, or no treatment; O, the primary outcome include measure will be the decrease in liver fibrosis score, and the secondary outcomes include the index of liver fibrosis. All the included data will be analyzed with the software of Review Manager 5.2 and STATA 14.2. DISCUSSION The purpose of this study is to conduct a systematic review and meta-analysis to assess the effects on anti-liver fibrosis of Sal B, and this will be contribute to drug development and pathological mechanisms of clinical research.
