Abstract
OBJECTIVE The aim of this study was to explore the roles of FOXN2 (Fork head Box N2) in mediating the proliferation and invasion of hepatocellular carcinoma (HCC) cells. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to determine expression of FOXN2 in HCC tissues and cells. Transfection of plasmid containing FOXN2 was used to exogenously overexpress FOXN2 in vitro. Cell Counting Kit-8 (CCK-8) assay and transwell assay were applied to detect the proliferation and invasion of HCC cells, respectively. RESULTS FOXN2 expression decreased significantly in both HCC tissues and cells (p<0.05). Upregulation of FOXN2 significantly inhibited the proliferation and invasion of HCC cells (p<0.05). CONCLUSIONS FOXN2 acts as a regulator in the progression of HCC. Our findings suggest that FOXN2 may be a novel therapeutic monitoring and prognosis biomarker in HCC.

Abstract
OBJECTIVE To investigate the relationship between electrocardiographic changes and erythropoietin (EPO) level in stable coronary artery disease (CAD) patients with autonomic nerve functional damage. PATIENTS AND METHODS Clinical data of 96 stable CAD patients who were treated in our hospital from January 2017 to December 2019 were retrospectively analyzed. All patients were grouped according to whether autonomic nerve function damage was combined; the baseline characteristic data and the morphological characteristics of ECG scattergram were compared between 2 groups, and the relationship between ECG scattergram and EPO level & autonomic nerve function was analyzed. RESULTS The levels of EPO and red cell volume distributing width (RDW) in stable CAD patients with autonomic nerve dysfunction were significantly higher than that of CAD patients without autonomic nerve dysfunction (p<0.05). The length of scattergram in stable CAD patients with autonomic nerve dysfunction was significantly shorter than that of those without autonomic nerve dysfunction (p<0.05). The cometary sign proportion of ECG scattergram in stable CAD patients with autonomic nerve dysfunction was significantly lower than that of stable CAD patients without autonomic nerve dysfunction (p<0.05). There was negative correlation between EPO levels and scattergram length in stable CAD patients with and without autonomic nerve dysfunction (r=0.44, p=0.02). There was no correlation between EPO levels and scatter width in stable CAD patients with and without autonomic nerve dysfunction (r=0.10, p=0.58). The results of binary logistic regression analysis showed that EPO level was the independent risk factor for the occurrence of autonomic dysfunction in patients with stable CAD (p<0.05). The length of scattergram was the independent protective factor of autonomic nerve function impairment in patients with stable CAD (p<0.05). The AUC of EPO level and scattergram was 0.74 and 0.72 respectively, both of which have similar prediction value. CONCLUSIONS The level of EPO in stable CAD patients with autonomic nerve dysfunction was related to the change of ECG; and the EPO level and scattergram length can be used to predict the occurrence risk of autonomic nerve dysfunction.

Abstract
Background:Idiopathic inflammatory myopathies (IIM) was associated with a significantly higher risk of opportunistic infections that including Pneumocystis jiroveci pneumonia(PJP) which is potentially fatal opportunistic infection. However, no prior studies have evaluated the PJP infection in subtypes of IIM.Objectives:To investigate the incidence rate and mortality rate of PJP infection in subgroups of IIM patients according to myopathy specific antibodies.Methods:In the first part, we reviewed 463 consecutive patients with IIM retrospectively to analyze incidence of PJP infection. In the next part, we enrolled 30 consecutive PJP infection patients with any rheumatic disease was to identify the mortality rate and risk factors. Kaplan-Meier curve with log rank test was used to access differences in survival. Univariate and multivariate analyses were performed to identify prognostic factors using Cox regression.Results:We found that 12(7.5%) PJP cases occurred in 160 anti-MDA5-ab-positive DM patients, while only two (0.7%) PJP cases were found in 303 anti-MDA5-ab-negtive DM/PM patients(P < 0.05). PJP infection typically happened in the first two months of the treatment for anti-MDA5-ab-positive DM patients who have a significant decrease in the CD4+ T cell counts and Lymphocyte counts (P < 0.05). Only two (16.7%) anti-MDA5-ab-positive DM patients recover from PJP, with lethally higher mortality than those PJP infection with other rheumatic diseases (83.3% vs. 38.9%, P < 0.05). We found no association between the time to anti-PJP treatment and treatment outcomes in anti-MDA5-ab-positive DM; yet we confirmed in PJP infection with other rheumatic diseases that anti-PJP treatment within 6 days crucially increased the survival (P < 0.05).Conclusion:PJP infection has alarming high incidence and mortality in anti-MDA5-ab-positive DM patients. Unlike PJP infection with other rheumatic diseases, timely treatment for PJP doesn’t improve the prognosis of this particular subtype. Therefore, the necessity of further study of PJP prophylaxis treatment in anti-MDA5-ab-positive DM patients is verified.References:[1]Hsu CY, et al.

Abstract
Background:Primary Sjögren’s syndrome (pSS) is a relatively common autoimmune disease characterized by oral and ocular dryness. An increasing number of studies have revealed that long non-coding RNA (lncRNA), miRNA, mRNA and circular RNA (circRNA) contributes to the pathogenesis of autoimmune diseases.Objectives:To explore lncRNA, miRNA, mRNA and circRNA expression profiles in labial salivary glands (LSGs) in pSS patients and their biological functions in the regulation of pSS.Methods:The expression of 75,550 lncRNAs, 2,318 miRNA, 20,292 mRNAs and 6,877 circRNAs were determined in the LSG of six pSS patients and six healthy controls using microarray experiments. Validation was performed in pSS patients and controls using real-time PCR. LncRNA-mRNA co-expression and gene-pathway networks were constructed using bioinformatics software.Results:A total of 599 lncRNAs (upregulated: 279, downregulated: 320), 78 miRNAs (upregulated: 26, downregulated: 52), 615 mRNAs (upregulated: 590, downregulated: 25) and 160 mRNAs (upregulated: 110, downregulated: 50) were differentially expressed in the LSGs of pSS patients. Five of these lncRNAs were validated using real-time PCR. lncRNA HCP5, lncRNA SNHG5, lncRNA IFI44L, lncRNA CMPK2 were significantly upregulated and lncRNA TTYH1 were downregulated in pSS. GO and KEGG biological pathway analysis were performed to predict the functions of differentially expressed lncRNAs and co-expressed potential targeting genes. Subsequently, a ceRNA (lncRNA-miRNA-mRNA) network including 2320 ceRNA pairs was constructed based on predicted miRNAs shared by lncRNAs and mRNAs.Conclusion:The expression profile provided a systematic perspective on the potential functions of lncRNAs miRNAs, mRNAs and circRNAs in the pathogenesis of pSS. Therefore, this study will aid in the development of new diagnostic biomarkers and drug therapies.References:[1]Le Dantec C, Varin MM, Brooks WH, Pers JO, Youinou P, Renaudineau Y.

Abstract
OBJECTIVE To study whether serum estradiol (E2) levels prior to progesterone administration in the artificial endometrial preparation (AEP) of frozen-thawed blastocyst transfer affect the live birth rate. DESIGN Retrospective cohort study. SETTING Tertiary-care academic medical centre. POPULATION A total of 3857 frozen-thawed blastocyst transfer cycles were divided into three groups: <200 pg/ml (n = 1676); 200-399 pg/ml (n = 1296); and ≥400 pg/ml (n = 885), based on the 25th (182.3 pg/ml) and 75th percentile (390.2 pg/ml) of serum E2 level prior to progesterone administration. METHODS Univariable and multivariable logistic regression analysis was performed. MAIN OUTCOME MEASURES The primary outcome of the study was the live birth rate and the secondary outcomes included clinical pregnancy rate, pregnancy loss rate, neonatal birthweight, Z-score, and small for gestational age (SGA). RESULTS Compared with the reference group, accounting for major covariates, the live birth rate significantly decreased in the '≥400 pg/ml' group (adjusted OR 0.71, 95% CI 0.59-0.85). Compared with the reference group, there was an association between the E2 level in the '≥400 pg/ml' group and a decrease in the clinical pregnancy rate (adjusted OR 0.74, 95% CI 0.61-0.89). Compared with the reference group, the pregnancy loss rate significantly increased in the '≥400 pg/ml' group (adjusted OR 1.45, 95% CI 1.08-1.93). The E2 levels did not affect neonatal birthweight, Z-score, and SGA among singletons. CONCLUSIONS High serum E2 levels prior to progesterone administration in AEP are associated with a decreased live birth rate after frozen-thawed blastocyst transfer. TWEETABLE ABSTRACT High serum E2 levels prior to progesterone administration in artificial FET are associated with a decreased live birth rate after frozen-thawed blastocyst transfer.

Abstract
Apical periodontitis (AP), an inflammatory lesion around the apex of tooth roots, is mostly caused by dental pulp infection. Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays a vital role in regulating cholesterol homeostasis by targeting low-density lipoprotein receptor (LDLR) and participates in bacterium-induced chronic periodontitis. However, the roles of PCSK9 in AP are unknown. Here, we investigated its role in AP by using Pcsk9-/- mice. Micro-computed tomography scanning and histological staining revealed that the periapical bone loss of Pcsk9-/- mice was greater than that of wild-type (WT) mice, and increased expression of inflammation-related factors tumor necrosis factor α (TNF-α) and interleukin (IL)-6 was also observed. Immunofluorescence staining and quantitative real-time polymerase chain reaction showed PCSK9 expression in bone marrow macrophages (BMMs) was increased after treatment with lipopolysaccharide (LPS). This finding was consistent with the in vivo results that the expression level of PCSK9 in exposed WT mice increased compared with that in unexposed WT mice. After LPS challenge, the expression levels of TNF-α, IL-1β, and IL-6 in BMMs were increased, and Pcsk9 knockout aggravated the expression of these inflammatory factors. The number of osteoclasts positive for tartrate-resistant acid phosphatase staining around the apical lesion in Pcsk9-/- mice was higher than that in WT mice. Then BMMs underwent the osteoclast differentiation. Pcsk9 knockout BMMs induced increased and larger osteoclasts. While this effect of Pcsk9 knockout was abolished by the addition of Ldlr small interfering RNA, revealing that Pcsk9 knockout increased osteoclastogenesis was dependent on the LDLR. Immunohistochemistry staining showed increased expression level of LDLR in exposed Pcsk9-/- periapical areas. In vitro experiments showed that LPS promoted the expression level of LDLR in Pcsk9-/- BMMs and increased osteoclast formation ability, indicating that LPS promoted the elevation of osteoclasteogenesis caused by the Pcsk9 knockout. In conclusion, Pcsk9 deficiency aggravated the inflammatory response and promoted the osteoclastogenesis in an LDLR-dependent manner in AP experimental mice.

Abstract
Theabrownin (TB), a natural compound present in the fresh leaves of green tea, is a potential antitumor agent. However, so far whether and how TB affects glioma is unclear. In this study, we investigated the effect of TB on astroglioma and oligodendroglioma cells. Surprisingly, TB significantly reduced the viabilities of HOG and U251 cells in a dose-dependent manner, which was accompanied by the upregulation of active-Casp-3, Bax, and PTEN; meanwhile, the antiapoptotic gene Bcl-2 was downregulated. In addition, TB treatment induced cell cycle arrest at the G1 and G2/M phases in HOG and U251 cells, respectively. TB treatment caused the downregulating of c-myc, cyclin D, CDK2, and CDK4 and upregulating of p21 and p27 in the HOG cell, while TB increased P53, p21, and p27 levels and decreased the levels of cell cycle regulator proteins such as CDK and cyclin A/B in the U251 cells. Therefore, the c-myc- and P53-related mechanisms were proposed for cell cycle arrest in these two glioma cell lines, respectively. Overall, our findings indicated that TB could be a novel candidate drug for the treatment of gliomas.

Abstract
OBJECTIVE To investigate the expression and clinical significance of costimulatory molecule B7-H3 and microRNA-145 (miR-145) in lung cancer patients with malignant pleural effusion. PATIENTS AND METHODS A total of 100 cases of patients with lung cancer who admitted to our hospital for treatment from March 2017 to September 2018 were selected. Forty-nine cases of patients diagnosed with malignant pleural effusion were included in the study group, and 51 cases with benign pleural effusion in the control group. The content of B7-H3 in pleural effusion of the two groups was detected by enzyme-linked immunosorbent assay (ELISA), and the expression of miR-145 in pleural effusion of the two groups was analyzed by Real-time quantitative PCR (qRT-PCR). The relationships between the expressions of B7-H3 and miR-145 and the clinicopathological characteristics were analyzed. The diagnostic value of B7-H3 and miR-145 in lung cancer was analyzed. RESULTS The expression level of B7-H3 in the study group was significantly higher than that in the control group (p<0.050), while the expression level of miR-145 was significantly lower than that in the control group (p<0.050). The expression levels of B7-H3 and miR-145 in the study group were correlated with lymph node metastasis, differentiation degree of lung cancer and TNM stage (p<0.001). The sensitivity and specificity of miR-145 in single diagnosis of lung cancer were 64.71% and 79.59%, respectively. The sensitivity and specificity of B7-H3 in single diagnosis of lung cancer were 80.39% and 61.22%, respectively. CONCLUSIONS B7-H3 and miR-145 are abnormally expressed in lung cancer, and are closely related to the lymphatic metastasis, differentiation degree and TNM stage of lung cancer. They may be potential markers for the diagnosis of malignant pleural effusion in lung cancer in the future.

Abstract
Common variable immunodeficiency disorders (CVID) are multi-system disorders where target organ damage is mediated by infective, autoimmune and inflammatory processes. Bronchiectasis is probably the most common disabling complication of CVID. The risk factors for bronchiectasis in CVID patients are incompletely understood. The New Zealand CVID study (NZCS) is a nationwide longitudinal observational study of adults, which commenced in 2006. In this analysis, the prevalence and risk factors for bronchiectasis were examined in the NZCS. After informed consent, clinical and demographic data were obtained with an interviewer-assisted questionnaire. Linked electronic clinical records and laboratory results were also reviewed. Statistical methods were applied to determine if variables such as early-onset disease, delay in diagnosis and increased numbers of infections were associated with greater risk of bronchiectasis. One hundred and seven adult patients with a diagnosis of CVID are currently enrolled in the NZCS, comprising approximately 70% of patients known to have CVID in New Zealand. Fifty patients (46·7%) had radiologically proven bronchiectasis. This study has shown that patients with compared to those without bronchiectasis have an increased mortality at a younger age. CVID patients with bronchiectasis had a greater number of severe infections consequent to early-onset disease and delayed diagnosis. Indigenous Māori have a high prevalence of CVID and a much greater burden of bronchiectasis compared to New Zealand Europeans. Diagnostic latency has not improved during the study period. Exposure to large numbers of infections because of early-onset disease and delayed diagnosis was associated with an increased risk of bronchiectasis. Earlier diagnosis and treatment of CVID may reduce the risk of bronchiectasis and premature death in some patients.

Abstract
Objective: To evaluate the safety and efficacy of stent-assisted coil embolization in patients with recurrent intracranial bifurcation aneurysms,after initial simple coiling or microsurgical clipping. Methods: Clinical data of 20 patients with recurrent intracranial bifurcation aneurysms who initially underwent simple coiling or surgical clipping and subsequently re-treated by stent-assisted coiling embolization at the Radiology Intervention Department of Huashan Hospital between March 2009 and November 2019 were collected and analyzed retrospectively.There were 9 males and 11 females,with a median age of 55.5 years (range:33 to 71 years),including 17 aneurysms initially treated with simple coiling and 3 treated with surgical clipping.All cases were re-treated with stent-assisted coiling,15 using a single stent and 5 employing two stents in a Y-configuration.Peri-and post-operative complications and outcomes were evaluated.Mann-Whitney U tests were performed to compare the follow-up duration between initial treatment and re-treatment.Student's t tests were used to compare the parent artery angles before re-treatment, after re-treatment and at the last follow-up. The parent artery angle was defined using the proximal main trunk and the stented branch. Results: Immediate complete occlusion (Raymond Ⅰ) was achieved in 18 aneurysms (90.0%) while 2 aneurysms (10.0%) had a residual neck (Raymond Ⅱ).The median follow-up time(M(QR)) was 8.5(16.3)months,which had no significantly different from the initial treatment follow-up duration (15.5(27.0)months)(U=157.7,P=0.25). During the follow-up period,2 aneurysms (10.0%) with immediate post-operative residual necks recanalized again,including 1 aneurysm re-treated with the Y-configuration stent.Symptomatic thromboembolic complications occurred in 6 patients,including 4 re-treated with the Y-configuration stent.No peri-operative hemorrhagic complications occurred,along with no operation-related permanent disability or death. The parent artery angle increased significantly from pre-operative(90.1±21.1)°to post-operative and the last follow-up ((115.4±28.9)° and (132.6±26.8)°);t=5.14,P<0.01;t=7.78,P<0.01). Conclusion: For recurrent intracranial bifurcation aneurysms after initial surgical clipping or simple coiling,stent assisted coil embolization is proved to be safe and can decrease recurrence rate.

Abstract
Autism spectrum disorder (ASD), a representative disease of children's neurodevelopmental disorders, brings huge pressure and financial burden to families and society. It is of great significance to explore its etiology and pathogenesis. Therefore, we established an ASD Cohort based on the existing China National Birth Cohort (CNBC), which applied parallel design to recruit and follow up families who achieved pregnancy after receiving assisted reproductive technologies (ART) and families with spontaneous conception. The main aims of this study are to compare the incidence of ASD among children born after ART with those born under spontaneous pregnancy, and to evaluate the impact of ART on the neurobehavioral development of offspring. Additionally, with a variety of clinical and behavioral related information collected during pregnancy and at early life of offspring, we are able to investigate the risk factors associated with ASD comprehensively. This article briefly introduces the objectives, contents, preliminary progress, strength and limitations, as well as further prospects of the ASD cohort study, mainly focusing on the overall design and current progress.

Abstract
OBJECTIVE Myocardial ischemia-reperfusion injury (MIRI) is a common problem in heart-related diseases. The aim of this study was to explore the protective effects of STRAP on cardiomyocytes in the MIRI process and its mechanisms. MATERIALS AND METHODS We used SD rats to construct a MIRI model and increased the expression of STRAP in myocardial tissue by Entranster to detect the effect of STRAP on rat myocardial tissue. In addition, we cultured rat cardiomyocyte cell line H9c2 cells and constructed a hypoxia-reoxygenation model to detect the protective effect of STRAP on H9c2 cells. LY294002, an inhibitor of the PI3K/PDK1/Akt signaling pathway, was used to validate the mechanism by which STRAP protects cardiomyocytes. RESULTS Overexpression of STRAP significantly reduced the activity of MDA in myocardial tissue and increased the activity of SOD. STRAP also substantially lowered CK and LDH levels in rat serum and increased Na+-K+-ATPase and Ca2+-Mg2+-ATPase activity. In addition, overexpression of STRAP considerably reduced endoplasmic reticulum stress (ERS) and apoptosis levels in H9c2 cells. However, LY294002 attenuated the protective effect of STRAP on cardiomyocytes. CONCLUSIONS STRAP reduces ERS and apoptosis in cardiomyocytes by activating the PI3K/PDK1/Akt signaling pathway, thereby reducing myocardial MIRI.

A novel dentin bonding scheme based on extrafibrillar demineralization combined with covalent adhesion using a dry-bonding technique. Bioact Mater 2021; 6:3557-3567. [PMID: 33842741 PMCID: PMC8022110 DOI: 10.1016/j.bioactmat.2021.03.024] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 02/26/2021] [Accepted: 03/11/2021] [Indexed: 01/21/2023] Open
Abstract
Dentin bonding is a dynamic process that involves the penetration of adhesive resin monomers into the extrafibrillar and intrafibrillar demineralized collagen matrix using a wet-bonding technique. However, adhesive resin monomers lack the capacity to infiltrate the intrafibrillar space, and the excess water that is introduced by the wet-bonding technique remains at the bonding interface. This imperfectly bonded interface is inclined to hydrolytic degradation, severely jeopardizing the longevity of bonded clinical restorations. The present study introduces a dentin bonding scheme based on a dry-bonding technique, combined with the use of extrafibrillar demineralization and a collagen-reactive monomer (CRM)-based adhesive (CBA). Selective extrafibrillar demineralization was achieved using 1-wt% high-molecular weight (MW) carboxymethyl chitosan (CMCS) within a clinically acceptable timeframe to create a less aggressive bonding substance for dentin bonding due to its selectively extrafibrillar demineralization capacity. CMCS demineralization decreased the activation of in situ collagenase, improved the shrinking resistance of demineralized collagen, and thus provided stronger and more durable bonding than traditional phosphoric acid etching. The new dentin bonding scheme that contained CMCS and CBA and used a dry-bonding technique achieved an encouraging dentin bonding strength and durability with low technical sensitivity. This bonding scheme can be used to improve the stability of the resin-dentin interface and foster the longevity of bonded clinical restorations.

Abstract
OBJECTIVE Rat intervertebral disc (IVD) is one of the most commonly used and cost-effective alternative models for human IVD. Many IVD related clinical studies need to be pre-tested on rat IVDs. However, studies on the heterogeneous cell clusters of the rat IVD are inadequate, and a further understanding of the marker genes and cell phenotypes of healthy mature IVD cells is essential. METHODS In this study, we used the 10X Genomics technology to analyze the single-cell transcriptome of purified wild-type rat IVDs. RESULTS We identified potentially new gene markers of IVDs via single-cell sequencing. Based on the unsupervised cluster analysis of 13,578 single-cell transcripts, 3 known IVD cell types were identified. We provided a complete single-cell gene expression map of the IVD. Immunohistochemical and immunofluorescence images of rat disc sections confirmed the new marker genes of all cell types. One group of heterologous cell groups expressed multi-functional stem cell (MSC)-specific genes, indicating the stem cell potential of IVD cells. CONCLUSION We provided the phenotype and marker genes of IVD cells at the single-cell level, reconfirmed existing data, and proposed new marker genes, including MSC marker genes. By identifying more accurate target cells and genes, our results pave the way for further study of the response of individual disc cells to disease states and provide the basis for future disc regeneration therapies.

Abstract
OBJECTIVE To study the influence of micro ribonucleic acid (miR)-155 on depression-like behaviors of depression mice, and to explore the role of Wnt/b-catenin signaling pathway in behavioral regulation of depression mice. MATERIALS AND METHODS The mouse model of depression was established via chronic unpredictable mild stress (CUMS). All mice were randomly divided into control group (n=12), model group (n=12), and fluoxetine group (n=12). The expression level of miR-155 in the hippocampus of mice in each group was detected via quantitative Polymerase Chain Reaction (qPCR). The changes in the behaviors of mice in each group were evaluated via behavioral experiments. The apoptosis level in the hippocampus of mice in each group was detected via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. Moreover, the content of inflammatory factors in the hippocampus of mice in each group was detected using the enzyme-linked immunosorbent assay (ELISA) kits. The expression levels of Wnt/b-catenin signaling pathway-related proteins in each group were detected via Western blotting. RESULTS The expression level of miR-155 in the hippocampus was significantly higher in model group than that in control group (p<0.01). Meanwhile, the expression level of miR-155 was significantly lower in fluoxetine group than that in model group (p<0.01). There were no statistically significant differences in the crossing score and rearing score in the open field test among groups (p>0.05). Compared with those in control group, the immobility time in tail suspension test and forced swimming test were significantly increased (p<0.01), while the sucrose preference degree significantly declined (p<0.01) in model group. Fluoxetine could significantly reduce the immobility time in tail suspension test and forced swimming test (p<0.01) and increase the sucrose preference degree (p<0.01) in model group. The number of TUNEL-positive cells in the hippocampus of mice in model group was significantly larger than that in control group (p<0.01). Fluoxetine could effectively reduce the number of TUNEL-positive cells in the hippocampus (p<0.01). Compared with those in control group, the content of tumor necrosis factor-α (TNF-a), interleukin-1b (IL-1b), and IL-6 in the hippocampus was significantly increased (p<0.01), while the content of IL-10 was significantly decreased (p<0.01) in model group. Fluoxetine could effectively reduce the content of TNF-a, IL-1b, and IL-6 (p<0.01) and increase the content of IL-10 (p<0.01). Besides, in model group, the expression levels of dishevelled-1 (DVL-1) and b-catenin in hippocampus remarkably declined (p<0.01), while the expression levels of glycogen synthase kinase-3b (GSK-3b) and adenomatous polyposis coli (APC) were remarkably increased (p<0.01) compared with those in control group. Fluoxetine could effectively lower the expressions of GSK-3b and APC in the hippocampus (p<0.01) and increase the expressions of DVL-1 and b-catenin (p<0.01) in model group. CONCLUSIONS MiR-155 is involved in regulating the depression-like behaviors of depression mice through promoting the release of inflammatory factors and the apoptosis of hippocampal neurons. Its mechanism may be related to the inhibition of the Wnt/b-catenin signaling pathway.

Abstract
Grains and feed are severely contaminated by deoxynivalenol (DON) globally, threatening both human and animal health. Research on bio-degradation of DON, in general, is gaining attention. The aim of this research was to estimate the effect of Clostridium sp. WJ06 as a microbiological detoxification of DON based on the expression and distribution of proliferating cell nuclear antigen (PCNA) as well as ghrelin in the small intestine. A total of 24 fattening pigs were randomly divided into three groups. The control group was fed with a basic diet, the DON group was fed with DON at 5.0 mg/kg in feed, and the DON+C group was provided DON feed with Clostridium sp. WJ06. Several selected blood parameters, the intestinal morphology, and the expression and distribution of PCNA and ghrelin, were evaluated. The results proved that the selected blood parameters were altered, the intestinal villi were damaged, the epithelium was shed, as well as the expression and distribution of PCNA and ghrelin were changed by DON exposure. These toxic effects were prevented by the addition of Clostridium sp. WJ06. In short, the addition of Clostridium sp. WJ06 to the feed may eliminate the toxic effects of DON in fattening pigs. An underlying mechanism is likely modulation of the expression and distribution of PCNA and ghrelin.

Abstract
OBJECTIVES To investigate the general occurrence and clinical significance of absence of heterozygosity (AOH), detected by single-nucleotide polymorphism (SNP) array on prenatal diagnosis. METHODS We recruited pregnancies undergoing invasive prenatal diagnosis at our fetal medicine center over a 6-year period. All fetuses underwent SNP array using the Affymetrix CytoScan HD array platform. AOH was defined as a chromosomal homozygosity segment with neutral copy number. Cases with AOH over 10 Mb in size or with suspected pathogenicity were further analyzed, and the clinical features and outcome were reviewed. RESULTS Of 10 294 recruited fetuses, 100 (0.97%) with AOH were identified; in 81 (81.0%) of these, AOH occurred in a single chromosome, while 19 (19.0%) patients had multiple AOHs in different chromosomes. AOH was observed in all chromosomes, chromosomes X, 2 and 16 being the most frequently involved. The length of AOH ranged from partial chromosome (9.002-80.222 Mb) to the entire chromosome. Similar AOH regions displayed varied clinical manifestations. In total, 55 patients presented with concomitant ultrasound abnormalities, the most common being multiple abnormalities (14/55 (25.5%)), genitourinary malformations (8/55 (14.5%)), skeletal malformations (5/55 (9.1%)) and small-for-gestational age (5/55 (9.1%)). Notably, the rate of adverse perinatal outcome (including termination of pregnancy, neonatal death, fetal death, selective reduction and miscarriage) in fetuses with AOH and ultrasound abnormalities (30/48 (62.5%)) was higher than in those without ultrasound abnormalities (6/40 (15.0%)) (P < 0.001). Further non-invasive prenatal testing using cell-free fetal DNA from maternal blood indicated chromosomal copy number abnormalities in 11 patients; however, they were confirmed as AOH by SNP array of the amniotic fluid. CONCLUSIONS Genetic counseling regarding a prenatal diagnosis of AOH remains challenging. To evaluate comprehensively its significance, we propose a management strategy involving further serial ultrasound examinations, parental verification, whole-exome sequencing, placental study and effective follow-up.

Abstract
We present results from the SPring-8 Angstrom Compact free electron LAser facility, where we used a high intensity (∼10^{20} W/cm^{2}) x-ray pump x-ray probe scheme to observe changes in the ionic structure of silicon induced by x-ray heating of the electrons. By avoiding Laue spots in the scattering signal from a single crystalline sample, we observe a rapid rise in diffuse scattering and a transition to a disordered, liquidlike state with a structure significantly different from liquid silicon. The disordering occurs within 100 fs of irradiation, a timescale that agrees well with first principles simulations, and is faster than that predicted by purely inertial behavior, suggesting that both the phase change and disordered state reached are dominated by Coulomb forces. This method is capable of observing liquid scattering without masking signal from the ambient solid, allowing the liquid structure to be measured throughout and beyond the phase change.

Abstract
Platygaster robiniae Buhl and Duso (Hymenoptera: Platygastridae) is an egg-larvae parasitoid of the black locust gall midge (Obolodiplosis robiniae) (Haldeman) (Diptera: Cecidomyiidae) which is a serious invasive pest in China, where it attacks an important hardwood species, the black locust tree, Robini pseudoacacia L. (Fabales: Fabaceae). Despite the use of P. robiniae as an effective biocontrol agent, the absence of sequence data and other molecular markers have limited its genetic applications for pest management in forests. Simple-sequence repeats (SSRs) are valuable molecular markers for population genetic structure studies. In the present study, we identified 14,123 SSRs, of which 7799 SSR primer pairs were successfully designed. Subsequently, 240 SSR were chosen and tested with 48 P. robiniae accessions from two geographically separated populations in north and south China. Of these, 34 were polymorphic, with an average of three alleles (Na) and four genotypes (NG) each. The average values of observed heterozygosity (Ho) was 0.3514, expected heterozygosity (He) 0.4167, Shannon's information index (I) 0.7143, and polymorphism information content (PIC) 0.3558, respectively. Neighbour joining analysis (bootstrap 1000) revealed that Chengdu (CD) and Dangdong (DD) popluations clustered into two main divisions, and some individuals from two popluations clustered together as the third devision, which indicated the gene flow and genetic differentiation were present between two populations. Our finding indicates that these SSR markers will be useful for further studies on the genotype identification and genetic mapping of the genus Platygaster.

Abstract
OBJECTIVES Understanding the determinants of HIV immune control is important for seeking viable HIV prevention, treatment and curative strategies. The antigen-specific roles of CD8 T cells in controlling primary HIV infection have been well documented, but their abilities to control the latent HIV reservoir is less well studied. METHODS The scientific literature on this issue was searched on PubMed. RESULTS Recent reports have demonstrated that CD8 T cells are also involved in the control of viral replication in HIV-infected individuals receiving antiretroviral therapy (ART). However, based on accumulating evidence, the antiviral role of CD8 T cells in ART patients may not be achieved via an antigen-specific manner as HIV-specific CD8 T cells can sense, but not effectively eliminate, cells harbouring intact provirus without first being activated. Our recent study indicated that virtual memory CD8 T cells, a semi-differentiated component of CD8 T cells, may be involved in the mechanism restraining the HIV DNA reservoir in ART patients. CONCLUSIONS In this review, we summarize recent findings on the role of CD8 T cells in controlling HIV, highlighting differences between conventional antigen-specific and innate-like CD8 T cells. A better understanding of the roles of CD8 T cells during HIV infection should benefit the informed design of immune-based treatment strategies.

Abstract
OBJECTIVE Laryngocarcinoma is one of the most ordinary head and neck cancers worldwide. Recent studies have revealed that circular RNAs (circRNAs) act as an important role in malignant tumors and participate in tumorigenesis. The purpose of our work is to uncover how hsa_circ_0000285 functions in laryngocarcinoma. PATIENTS AND METHODS In this research, the Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was performed to monitor hsa_circ_0000285 expression in laryngocarcinoma samples. Besides, function assays were performed in laryngocarcinoma cells transfected with hsa_circ_0000285 shRNA or lentivirus. Furthermore, the RT-qPCR and Western blot assay were conducted to explore the target-signaling pathway of hsa_circ_0000285. RESULTS Hsa_circ_0000285 expression was found to be upregulated in laryngocarcinoma samples compared with adjacent tissues. The function assays showed that the inhibition of the cell proliferation was induced via knockdown of hsa_circ_0000285 in laryngocarcinoma in vitro, while the promotion of cell apoptosis was induced via the knockdown of hsa_circ_0000285 in laryngocarcinoma in vitro. On the other hand, the overexpression of hsa_circ_0000285 had the opposite function. In addition, the Wnt/β-catenin signaling pathway was repressed via knockdown of hsa_circ_0000285 in laryngocarcinoma, while the Wnt/β-catenin signaling pathway was promoted via overexpression of hsa_circ_0000285 in laryngocarcinoma. CONCLUSIONS In our study, hsa_circ_0000285 was first identified as a novel oncogene and could induce the Wnt/β-catenin signaling pathway in laryngocarcinoma.

Abstract
The submental artery perforator flap (SMAPF) has an elongated pedicle, allowing good cosmetic outcomes to be achieved following oral reconstruction surgery. The improper dissection of perforators often leads to a vascular flap crisis. To avoid this, some surgeons choose to carry amounts of connective tissue around the pedicle. However the inclusion of connective tissue on the pedicle raises concerns about oncological safety. A surgical anatomical study of the submental vessel patterns and subdivisions of the cervical level I lymph nodes was conducted on 33 patients with primary oral cancer who underwent reconstruction with a SMAPF after tumour resection. The variations in vessels and cervical level I lymph nodes observed during SMAPF harvesting were recorded and analyzed. Two patterns of submental artery perforators and three patterns of submental veins were identified. The different characteristics of the lymph node distribution were elucidated for five subdivisions. All SMAPFs survived (n=33, 100%); however, two SMAPFs exhibited partial losses. The 3-year survival rate of patients was 84.5±6.4%, and there were no suspected flap-related recurrences. With detailed anatomical information on the vascular system and lymph node subdivision, SMAPFs are a reliable choice for postoperative reconstruction following oral cancer surgery, meeting the standards for oncological safety.

Abstract
While there have been previous studies examining the relation between the rs17820943 and rs6072081 polymorphisms in the v-maf musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) gene and rates of nonsyndromic cleft lip with or without cleft palate (NSCL/P), at present the results of these studies have been inconsistent. This meta-analysis therefore aimed to conduct a more robust assessment of the association between the MAFB rs17820943 and rs6072081 polymorphisms and NSCL/P risk. The Embase, Web of Science, PubMed, the China National Knowledge Internet (CNKI), and Wanfang databases were systematically searched to identify relevant studies. In total, five studies incorporating 2769 patients and 2885 controls were identified assessing the rs17820943 polymorphism and three studies incorporating 1242 patients and 1310 controls assessing the rs6072081 polymorphism were identified. This analysis revealed the MAFB rs17820943 and rs6072081 polymorphisms to be linked to a significantly reduced NSCL/P risk (rs17820943: C vs T: OR=0.76, 95% CI=0.70-0.82; CC vs CT: OR=0.75, 95% CI=0.67-0.85; CC vs TT: OR=0.58, 95% CI=0.49-0.67; CC+CT vs TT: OR=0.67, 95% CI=0.59-0.77; CT+TT vs CC: OR=1.43, 95% CI=1.28-1.60; rs6072081: A vs G: OR=0.77, 95%CI=0.68-0.86; AA vs AG: OR=0.76, 95%CI=0.64-0.90; AA vs GG: OR=0.58, 95%CI=0.45-0.74; AA+AG vs GG: OR=0.68, 95%CI=0.54-0.84; AG+GG vs AA: OR=1.40, 95% CI=1.19-1.65). The results of the present meta-analysis indicate that in an East Asian population, for both rs17820943 and rs6072081 were associated with NSCL/P.

Abstract
Objective: To explor staging of the general course of occupational medicamentosa-like dermatitis due to trichloroethylene (OMDT) to better understand the characteristics of OMDT course, and to provide reference for clinical diagnosis and treatment and related studies. Methods: We collected main clinical manifestation and auxiliary examination data during hospitalization to May 2019 from 35 OMDT patients with complete course record who were hospitalized from January 2014 to December 2018. Continuous monitoring indicators with changing trends including main clinical manifestation indicators, peripheral white blood cell counts, liver function indicators such as serum alanine aminotransferase activity, myocardial enzyme indicators such as serum lactate dehydrogenase activity were selected and used with their standardized values to do cluster analysis on time point (week as unit) of the course of each patient. The clustering results combined with changing trends of the indicators were used to determine the stages of course of each patient, and therefore the staging of general course of OMDT was calculated. Positive rates or average levels of the indicators were compared between different stages, and the correlation of duration of each stage was analyzed with physical characteristics, disease characteristics and treatment measures of the patients. Results: General course of OMDT could be divided into acute phase (3.0±1.5) weeks and chronic phase (11.0±4.4) weeks, while chronic phase could be further divided into early period (5.0±3.0) weeks and later period (6.5±3.7) weeks. Compared with chronic phase, clinical manifestation indicators, white blood cell counts (except eosinophil count) , liver function indicators (except total protein and albumin concentration) , and myocardial enzyme indicators were all increased (all P<0.01) , while total protein and albumin concentration decreased (P<0.05 and P<0.01, respectively) in acute phase. Compared with later period of the chronic phase, clinical manifestation indicators (except fever) , white blood cell counts (except lymphocyte count) , liver function indicators (except total protein and albumin concentration) , and creatine kinase isoenzyme activity were all increased (all P<0.01) , while total protein, albumin concentration and creatine kinase activity decreased (all P<0.01) . Duration of acute phase were positively correlated with the time before glucocorticoid treatment (r(spearman)=0.62, P(adjust)<0.01) , and early and later periods of chronic phase were both positively correlated with corresponding duration of glucocorticoid treatment (r(spearman)=0.96, P(adjust)<0.01, r(spearman)=0.91, P(adjust)<0.01, respectively) . Conclusion: For the first time, the study objectively determined stages of general course of OMDT based on combination of multiple indicators, and analyzed characteristics of main indicators in each phase and potential factors related to the duration of each phase.

Abstract
The submental artery perforator flap (SAPF) has been a new option for the intraoral reconstruction of oral squamous cell carcinoma (OSCC) patients in recent years, but its surgical outcomes have not been well assessed. We compared the surgical outcomes and oncological safety of SAPF reconstruction for medium-sized soft-tissue defects after the ablation of primary oral cancer with traditional submental island flaps (SIF) and anterolateral thigh perforator flaps (ALTPF). Fifty-one SAPFs, 30 SIF, and 74 ALTPF were reviewed for the intraoral medium-sized reconstructions after the ablation of oral cancer from our institutional clinical oncological databases. We performed comparative assessments on the variables of surgical outcome and oncological safety among the 3 cohorts. A Kaplan-Meier estimate of survival for each flap was calculated. Operating time was significantly reduced in the SIF and SAPF groups than ALTPF (p = 0.021 and 0.014, respectively). Flap thickness of SAPF was the significantly thinnest (mean 0.5 cm) among three groups. The common complications of donor site for both SAPF and SIF group were incision dehiscence and orocutaneous fistula. There was no significant difference in disease-free survival (DFS) among the 3 groups. However, several OSCC patients with the SIF reconstruction were found to have recurrences with a metastatic lymph node under the flap after the first operation. SAPF could be a versatile choice of the intraoral reconstruction for the medium-sized soft-tissue defects after the ablation of oral cancer.

Abstract
OBJECTIVES The relationship between marijuana use and markers of chronic lung disease in people living with HIV (PLWH) is poorly understood. METHODS We performed a cross-sectional analysis of the Examinations of HIV-Associated Lung Emphysema (EXHALE) study, including 162 HIV-positive patients and 138 participants without HIV. We modelled marijuana exposure as: (i) current daily or weekly marijuana smoking vs. monthly or less often; or (ii) cumulative marijuana smoking (joint-years). Linear and logistic regression estimated associations between marijuana exposure and markers of lung disease, adjusted for tobacco smoking and other factors. RESULTS In PLWH, current daily or weekly marijuana use was associated with a larger forced vital capacity (FVC), larger total lung capacity and increased odds of radiographic emphysema compared with marijuana non-smokers in adjusted models; these associations were not statistically significant in participants without HIV. Marijuana joint-years were associated with higher forced expiratory volume in 1 s and FVC in PLWH but not with emphysema. CONCLUSIONS In PLWH, marijuana smoking was associated with higher lung volumes and potentially with radiographic emphysema. No consistently negative associations were observed between marijuana and measures of chronic lung health.

Abstract
Objective: To explore the the effectiveness of using short-latency somatosensory evoked potential(SLSEP) combined with electroencephalogram(EEG) reactivity to predict the prognosis of severe brain injury(SBI) patients. Methods: Consecutive patients with SBI admitted in neurosurgery intensive care unit(NSICU) at Xiangya Hospital of Central South University from July 2018 to January 2019 were prospectively collected. SLSEP and EEG were recorded in these patients in NSICU within two weeks after injury onset. EEG reactivity(EEG-R) was tested during EEG signal stabilization. In addition, the concentrations of serum neuron-specific enolase (NSE) and S100 protein were also detected. All patients were evaluated with Glasgow Outcome Scale(GOS) during 12 months' follow-up. GOS grade 3 to 5 was defined as favorable group, and GOS grade 1 to 2 was defined as unfavorable group. The association of relevant predictors with patient's prognosis was assessed. The area under the receiver operating characteristic (ROC) curve (AUC) was used to evaluate each potential predictor. Results: Forty-three patients were included in the study, with 26 patients of favorable outcomes and 17 patients with unfavorable prognosis. Univariate analysis revealed that the Glasgow Coma Scale (GCS) score, the concentration of serum NSE, EEG-R, the amplitude of SLSEP were all associated with the prognosis after 12 months' follow-up. Moreover, the AUC for prediction of favorable prognosis by GCS, NSE, EEG-R, SLSEP was 0.661(95%CI: 0.493-0.829), 0.697(95%CI: 0.531-0.862), 0.718(95%CI: 0.557-0.879) and 0.758(95%CI: 0.609-0.907) respectively. However, there was no significant difference of age, gender, pupillary light reflex and S100 protein between the two groups. Furthermore, multiple logistic regression analysis showed that only SLSEP amplitude (OR=2.058, 95%CI: 0.867-4.888) and EEG-R(OR=3.748, 95%CI: 0.857-16.394) were independent predictors of favorable prognosis, and the prognostic model containing these two variables yielded an predictive performance with an AUC of 0.798. Conclusion: The higher amplitude of SLSEP and the existence of EEG-R are predictors of good prognosis in SBI patients, and the combined use of SLSEP and EEG-R in predicting the prognosis of SBI patients is more reliable.

Abstract
Mineral nutrition plays a critical role in growth and bone mineralization in meat ducks as well as reproductive performance in duck layers and duck breeders. In addition to improving production performance parameters, minerals are also essential to support several enzymatic systems to enhancing antioxidant ability and immune function. This review explores the biological function and metabolism of minerals in the body, as well as mineral feeding strategy of various species of ducks. Topics range from mineral requirement to the physiological role of macroelements such as calcium and phosphorus and microelements such as zinc and selenium, etc. As with the improvement of genetic evolution and upgrade of rearing system in duck production, mineral requirements and electrolyte balance are urgent to be re-evaluated using sensitive biomarkers for the modern duck breed characterized by the rapid growth rate and inadequate bone development and mineralization. For duck breeders, mineral nutrition is not only required for maximal egg production performance but also for maintaining normal embryonic development and offspring's performance. Therefore, the proper amounts of bioavailable minerals need to be supplemented to maintain the mineral nutritional state of duck species during all phases of life. In addition, more positive effects of high doses microelements supplementations have been revealed for modern meat ducks subjected to various stresses in commercial production. The nutritional factors of mineral sources, supplemental enzymes, and antinutritional factors from unconventional ingredients should be emphasized to improve the effectiveness of mineral nutrition in duck feed formulation. Organic mineral sources and phytase enzymes have been adopted to reduce the antagonistic action between mineral and antinutritional factors. Therefore, special and accurate database of mineral requirements should be established for special genotypes of ducks under different rearing conditions, including rearing factors, environmental stresses and diets supplemented with organic sources, phytase and VD3.

Abstract
OBJECTIVES The purpose of this study was to compare the changes of the condylar axis, the anteroposterior condylar position relative to the glenoid fossa, after intraoral vertical ramus osteotomy (IVRO). STUDY DESIGN 21 patients diagnosed as skeletal class III malocclusion underwent IVRO and were followed according to the authors' postoperative management regimen. The three-dimensional positions of the condyles were evaluated by cone-beam computerized tomography (CBCT) at pre-op, post-op, and at follow-up. CBCT images were referenced to assess the condylar axis change and the anteroposterior condylar position in the glenoid fossa. A repeated-measures analysis of variance (P<0.05) also was performed. RESULTS After surgery, both the axial condylar angles and the anteroposterior condylar position were significantly different (P<0.05). The coronal condylar axis rotated outwardly. The anteroposterior condylar position in the glenoid fossa had moved from the concentric to the anterior position. But the condyle changes between post-op and follow-up (P>0.05) were insignificant. CONCLUSIONS With postoperative intermaxillary elastic traction, the condyles changed their positions physiologically for newly established jaw movement after IVRO.

Abstract
Objective: To investigate the association of cadmium exposure with liver function among adults in a non-ferrous metal mining area in Guangxi. Methods: A total of 310 residents aged 18 and above were recruited from 5 heavy metals polluted villages in a non-ferrous metal mining area in Guangxi from 2013 to 2014. The general demographic characteristics, blood cadmium levels and indicators of liver function index [Total bilirubin (TBIL), Glutamic oxaloacetic transaminase (AST), Alanine transaminase (ALT) and Glutamine transaminase (GGT)] were obtained by using questionnaire, physical examination and laboratory test. The blood cadmium levels were divided into quartiles as Q1-Q4 groups (using Q1 group as the reference).Multivariate logistic regression model was used to analyze the correlation between the blood cadmium level and functional liver index. Results: The age of subjects was (49.2±15.4) years, and 112 (36.1%) subjects were male residents. The prevalence of abnormal rates of TBIL,AST,ALT and GGT were 17.4% (54), 19.7% (61), 10.7% (33) and 11.9% (37), respectively. The geometric mean value of cadmium levels in adults was 3.72(95%CI: 3.43-4.02) μg/L. After adjusting for age, gender, body mass index (BMI), smoking, drinking, total cholesterol, hypertriglyceridemia and other factors, the risk of abnormal AST index in the highest concentration of blood cadmium group (Q4) was higher than that in the lowest concentration of blood cadmium group (Q1) (OR=2.92, 95%CI:1.07-7.98). Conclusion: The level of blood cadmium exposure is higher than the reference value of general population in China, and the elevated cadmium exposure is related to the increasing risk of AST abnormality.

Abstract
Macrophages are important members of innate immunity and play an extremely important role in the host defense against pathogenic infections, tumors, and allergic diseases. Macrophages have a high degree of plasticity, and may be polarized into classical activated macrophages (M1 macrophages) and alternative activated macrophages (M2 macrophages) under the stimulation of different environments. M1 macrophages are found to promote inflammatory responses, which facilitates the clearance of pathogens, while M2 macrophages may inhibit inflammatory responses, which facilitates the survival and reproduction of pathogens. This review summarizes the role of macrophage polarization in parasitic infections, so as to provide insights into the prevention and treatment of parasitic diseases.

Abstract
Survival rates for oral squamous cell carcinoma (OSCC) has remained stagnant in recent years and improving surgical mortality could be an avenue to enhance outcomes. This systematic review aims to identify the causes of mortalities, determine both the modifiable and non-modifiable factors involved and target a reduction in postoperative 30-day mortality. In May 2019, a comprehensive search of key databases including PubMed, EMBASE, Cochrane Library was conducted. Blinded selection by two researchers identified papers that included participants who received oral squamous cell carcinoma resection and suffered an in-hospital or 30-day mortality. Selection identified two relevant papers that meet the inclusion criteria. One study had one death in its population sample but only had the cause of death described. Another study had an overall surgical mortality rate of 1% in a population of 21,681. Patients with multiple factors had the highest mortality rates; 4.6% in patients >85 years old and have a T4 diagnosis, 3.9% in patients with a Comorbidity Index ≥1 and a T4 diagnosis. These studies did not determine relationships between factors and causes of death. There are significant knowledge gaps in the literature, that can be addressed through further population analysis studies.

Abstract
OBJECTIVE Long non-coding RNA (lncRNA) is a significant member of the non-coding RNA family. New evidence has shown that it plays a pivotal role in the processes of tumor genesis and development. According to previous verification, the lncRNA Tubulin Alpha 4B (TUBA4B) is a tumor-associated molecule, but how TUBA4B expresses and functions in breast cancer is still not clear. PATIENTS AND METHODS We conducted this study to examine what expression and biological role TUBA4B plays in breast cancer. The expression of TUBA4B was measured in breast cancer samples and cell lines. CCK8 assays and transwell assays were used for evaluating the effects of TUBA4B on breast cancer cell proliferation and invasion. Luciferase reporter assays were used for identifying the direct target of TUBA4B. RESULTS According to the results, TUBA4B was largely downregulated in breast cancer samples and cell lines. The functional analysis demonstrated that breast cancer cells proliferation and invasion could be inhibited by overexpression of TUBA4B. The results of Luciferase reporter assays indicated that TUBA4B directly targeted miR-19, which could rescue the effects of TUBA4B on breast cancer cells. CONCLUSIONS It is suggested that TUBA4B was downregulated in breast cancer and suppressed proliferation and invasion of breast cancer by targeting miR-19.

Abstract
The specific expression profile and function of circular RNAs (circRNAs) in mammalian ovarian follicles, especially during the atresia process, are unclear. In this study, genome-wide deep circRNA sequencing was applied to screen circRNAs in healthy and early atretic antral follicles in pig ovaries. A total of 40,567 distinct circRNAs were identified in follicles, among which 197 circRNAs (108 upregulated and 89 downregulated) were significantly shifted during the early atresia process. Most differentially expressed circRNAs (DECs) lacked protein-coding potential. Annotation analysis of the DECs revealed 162 known host genes, or noncoding RNAs, and 10 intergenic regions. The key pathways in which these host genes are involved include the focal adhesion-PI3K-Akt-mTOR signaling pathway, vascular endothelial growth factor A (VEGFA)-vascular endothelial growth factor receptor 2 signaling pathway and transforming growth factor-beta signaling pathway. Further comparison analysis between host genes of DECs and the differentially expressed linear messenger RNA transcripts revealed the cotranscription of circRNAs and their linear mRNAs in inhibin beta units (INHBA and INHBB), glutathione S-transferase (GSTA1), and VEGFA. In addition, we predicted 196 pairs of potential circRNA-micro RNA (miRNA) interactions among 77 DECs and 101 porcine miRNAs. We have identified 16 functional miRNAs by comparing the 101 miRNAs to the functional miRNAs reported in mammal ovarian follicle atresia and granulosa cell apoptosis studies. Our study adds new knowledge to circRNA distribution profiles in pig ovarian follicles, offers a valuable reference for transcriptomic profiles in the initiation of follicular atresia, highlights warranted circRNAs for further functional investigation, and provides possible biomarkers for ovarian dysfunctions.

Abstract
BACKGROUND Previous studies have demonstrated that pure transanal endoscopic surgery is safe and feasible in the treatment of rectal cancer. However, the role of pure transanal endoscopic colectomy in ascending colon cancer (ACC) treatment has not been evaluated. We report a case of transanal endoscopic surgery for ACC. METHODS A 35-year-old woman was treated for ACC, using a transanal endoscopic surgery device as the operation platform, and pure transanal endoscopic right hemicolectomy without transabdominal assistance was safely performed. An instrument suture, side-to-side, ileocolic anastomosis was performed. Operative time was 245 min and intraoperative blood loss was 60 ml. RESULTS The patient recovered well from the surgery. Compared with the traditional approach, this approach was less invasive and resulted in satisfactory outcomes and cosmesis (no scar). CONCLUSIONS Application of pure transanal endoscopic colectomy without abdominal assistance to ACC appears to be feasible and safe.

Abstract
Objective: To explore the association between serum levels of osteopontin (OPN) and systolic pulmonary artery pressure (sPAP) in healthy men following acute high altitude exposure. Methods: According to the inclusion and exclusion criteria, this observational study included 94 male subjects (aged from 18 to 30 years, dwelling in lowland<500 m) who ascended to Litang (4 100 m) from Chongqing (400 m) by bus with a stair-like journey within 7 days in June 2013. Data including basic information, OPN, superoxide dismutase (SOD), and malondialdehyde (MDA) and echocardiographic derived sPAP were collected within 48 hours before ascent and within 2-7 hours after arrival. Accordingly, subjects were divided into 3 groups based on the tertiles of sPAP after acute high altitude exposure: low sPAP group (26.8-32.3 mmHg (1 mmHg=0.133 kPa)) (n=31), middle sPAP group (32.4-37.4 mmHg) (n=32) and high sPAP group (37.5-55.6 mmHg) (n=31). Associations of serum OPN and SOD levels with sPAP were analysed by univariate and multivariate linear regression analysis. Results: After acute high altitude exposure, the levels of sPAP were significantly increased (P<0.001). There were no differences in age, height, weight, body mass index, percent of Han nationality and smoking among 3 subgroups. However, following acute high altitude exposure, the levels of heart rate, systolic and diastolic blood pressure elevated (all P<0.05), whereas the levels of oxygen saturation were reduced in the total subjects and all subgroups (all P<0.05). Moreover, systolic blood pressure of subjects in the high sPAP group was higher than that in low and middle sPAP groups (both P<0.05), and diastolic blood pressure of subjects in high sPAP group was higher than that in low sPAP group (P<0.05). The serum levels of OPN were increased in total cohort(27.9 (22.5,34.0) μg/L vs. 25.6 (18.4, 33.1) μg/L, P<0.05), and high sPAP group (P<0.05), whereas no differences were found in serum SOD and MDA levels among groups. Furthermore, the serum level of OPN in high sPAP group was higher than that in low sPAP group at high altitude (P<0.05), and there was a trend for decline in SOD level with increasing sPAP (P>0.05). Results from univariable linear regression analysis showed that the serum levels of OPN (r=0.32, P=0.002) and SOD (r=-0.22,P=0.032) were linearly correlated with sPAP in total cohort after high altitude exposure. Multivariate regression analysis showed that the serum levels of OPN(β=0.310,P=0.002) and SOD (β=-0.199,P=0.043) were independently associated with the levels of sPAP at high altitude. Conclusion: After acute high altitude exposure, the serum level of OPN is positively associated with sPAP, suggesting that OPN may be a novel bio-marker for predicting the increase of pulmonary pressure in response to acute high altitude exposure.
