Abstract
OBJECTIVE Long non-coding RNAs (lncRNAs) participate in multiple processes of malignant tumors, including glioma. In this study, we aimed to explore the effect of LINC00346 on glioma and its underlying mechanism. MATERIALS AND METHODS The Cancer Genome Atlas (TCGA) and the Chinese Glioma Genome Atlas (CGGA) databases were used to analyze the expression patterns and survival risk of LINC00346, miR-128-3p and SUZ RNA binding domain containing 1 (SZRD1) in glioma tissues. The binding sites were predicted by bioinformatic databases, and then, validated by Dual-Luciferase assay and RNA immunoprecipitation (RIP). qRT-PCR and Western blot were performed to evaluate the gene expression levels. CellTiter-Glo® and colony formation assays were used to detect the proliferation of glioma cells. Flow cytometric analysis was used to evaluate the apoptosis of glioma cells. The xenograft models were established to investigate the impact of LINC00346 on tumor growth in vivo. RESULTS We found that both LINC00346 and SZRD1 expression were negatively related to the poor overall survival rate in glioma patients. However, miR-128-3p showed the opposite effect of survival outcomes. LINC00346 knockdown remarkably restrained cell proliferation both in vitro and in vivo, as well as inducing apoptosis by acting as a molecular sponge of miR-128-3p. Moreover, miR-128-3p bound to SZRD1 3'-UTR in a sequence-specific manner. In addition, LINC00346 knockdown significantly inhibited the expression of SZRD1 and the inhibition could be reversed by miR-128-3p mimics. Furthermore, cell proliferation and apoptosis affected by LINC00346 were partially rescued by modulating miR-128-3p or SZRD1 expression. CONCLUSIONS LINC00346/miR-128-3p/SZRD1 axis played a crucial role in modulating the malignant progression of glioma, which may serve as a prognostic indicator and a probable therapeutic target for glioma.

Abstract
OBJECTIVE The aim of the study was to investigate the effect of lncRNA XIST on the proliferation and epithelial-mesenchymal transition (EMT) of retinoblastoma (RB) and its relevant mechanism. PATIENTS AND METHODS 60 RB patients who were treated in our hospital were collected. The expression of XIST in tissues and cells was detected by qRT-PCR, and the effect of XIST on the prognosis of RB cells was observed. Stable and transient over-expression and suppression vectors were established and transfected into RB cells WERI-RB1 and Y79. CCK-8, transwell, and flow cytometry were used to evaluate the proliferation, invasion, and apoptosis of transfected cells. Western Blot was used to detect apoptosis-related proteins and EMT-related proteins. Dual-Luciferase report was used to determine the relationship between XIST and miR-142-5p. RNA pull-down and RIP experiments were used to determine the relationship between XIST and miR-142-5p. RESULTS XIST was highly expressed in RB patients, which had a high diagnostic value. Patients with XIST high expression had a poor prognosis. After overexpression of XIST, the proliferation, invasion and EMT of cells increased, and apoptosis rate decreased, while inhibition of Ptv1 had the opposite effect. Dual-Luciferase report confirmed that XIST could target miR-142-5p. Functional analysis showed that the overexpression of miR-142-5p inhibited the proliferation, invasion and EMT of RB cells and promoted cell apoptosis. Rescue experiments showed that miR-142-5p could eliminate the inhibition of miR-142-5p on the proliferation, invasion, and EMT of RB cells by upregulating XIST expression. CONCLUSIONS Ptv1 can promote the proliferation, invasion, and EMT of RB cells by regulating miR-142-5p.

Abstract
Cementum, a specialized bony layer covering an entire molar root surface, anchors teeth into alveolar bone. Gli1, a key transcriptional activator in Hedgehog signaling, has been identified as a mesenchymal progenitor cell marker in various tissues, including the periodontal ligament (PDL). To address the mechanisms by which Gli1+ progenitor cells contribute to cementogenesis, we used the Gli1lacZ/+ knock-in line to mark Gli1+ progenitors and the Gli1CreERT2/+; R26RtdTomato/+ line (named Gli1Lin) to trace Gli1 progeny cells during cementogenesis. Our data unexpectedly displayed a biphasic feature of Gli1+ PDL progenitor cells and cementum growth: a negative relationship between Gli1+ progenitor cell number and cementogenesis but a positive correlation between Gli1-derived acellular and cellular cementoblast cell number and cementum growth. DTA-ablation of Gli1Lin cells led to a cementum hypoplasia, including a significant reduction of both acellular and cellular cementoblast cells. Gain-of-function studies (by constitutive stabilization of β-catenin in Gli1Lin cells) revealed a cementum hyperplasia. A loss of function (by conditional deletion of β-catenin in Gli1+ cells) resulted in a reduction of postnatal cementum growth. Together, our studies support a vital role of Gli1+ progenitor cells in contribution to both types of cementum, in which canonical Wnt/β-catenin signaling positively regulates the differentiation of Gli1+ progenitors to cementoblasts during cementogenesis.

Xu C, Wong VNL, Reef RE. Effect of inundation on greenhouse gas emissions from temperate coastal wetland soils with different vegetation types in southern Australia. THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 763:142949. [PMID: 33131859 DOI: 10.1016/j.scitotenv.2020.142949] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 09/30/2020] [Accepted: 10/08/2020] [Indexed: 06/11/2023]
Abstract
Predicted sea level fluctuations and sea level rise with climate change will lead to inundation of coastal and estuarine soils. Coastal wetlands usually contain large amounts of organic matter, which can be potential sources of greenhouse gas emissions (GHGs; CO2, CH4, N2O) during decomposition, but there are limited studies on the effects of sea level variation on GHGs in coastal wetlands. We measured the effect of brackish water inundation and wetting and drying cycles on GHG emissions from coastal wetland soil cores that supported four different vegetation types: Apium gravedens (AG), Leptospermum lanigerum (LL), Phragmites australis (PA) and Paspalum distichum (PD) from the estuarine floodplain of the Aire River in south-western Victoria, Australia. Intact soil cores were incubated under either dry, flooded, or a 14 day wet-dry cycle treatments for a total of 56 days at a constant temperature of 23 °C. CO2, CH4, and N2O fluxes were investigated in closed chambers and measured with gas chromatography. In the dry treatment, a positive correlation was found between soil organic carbon (SOC) and CO2 flux, and between SOC and CH4 flux. Higher SOC is indicative of higher amounts of soil organic matter (SOM) which acts as a source of substrate for microbes to produce CO2 or CH4 emissions under aerobic or anaerobic conditions. The NO2- and NO3- concentrations were positively correlated with N2O emissions in the wet-dry cycle treatment. NO2- and NO3- provide a supply of substrate for denitrification. The flooded treatment decreased cumulative CO2 emissions by 34%, 25% and 14% at the LL, PA, PD sites, respectively, and decreased cumulative N2O emissions by 42%, 39% and 43% at the AG, LL and PA sites, compared to the dry treatment. The wet-dry cycle treatment and dry treatment decreased cumulative CH4 emissions for all vegetation types compared to the flooded treatment. The redox potential (Eh) was negatively correlated with CH4 flux and positively correlated N2O flux at all sites. This study highlights the significance of sea level fluctuations when estimating GHG flux from coastal and estuarine floodplains which are highly vulnerable to inundation, and the role of SOC and mineral N as important drivers affecting GHG flux.

Abstract
OBJECTIVE Long non-coding RNAs (lncRNAs) play critical roles in tumour progression. However, the function of lncRNA small nucleolar RNA host gene 11 (SNHG11) in glioma has not been mentioned before. Our study aims to uncover the biological roles of SNHG11 in the progression of glioma and throw light for clinical treatment of glioma. MATERIALS AND METHODS The Gene Expression Profiling Interactive Analysis (GEPIA) dataset was used to analyze the SNHG11 expression between glioma and normal tissue, as well as survival benefit. The quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to detect SNHG11 and miR-154-5p expression. Celltiter-Glo, colony formation, and transwell assays were utilized to detect the influence of SNHG11 to the malignancy of U87 and U251 cells. The underlying pathways affected by SNHG11 were measured using Western blot. Furthermore, Luciferase reporter assay was applied to verify the interaction between SNHG11 and miR-154-5p. RESULTS SNHG11 was upregulated in glioblastoma tissues and five malignant glioma cell lines. SNHG11 expression was negatively correlated with overall survival of glioma patients. Moreover, silencing of SNHG11 could decrease glioma cell viability both in vitro and in vivo. Furthermore, the inhibition of SNHG11 suppressed proliferation, invasion and migration via regulating epithelial-mesenchymal transition (EMT). In addition, SNHG11 could bind miRNA-154-5p and negatively regulate its level. CONCLUSIONS SNHG11 functioned as an oncogene in glioma and promoted proliferation, invasion, and migration via EMT by sponging miR-154-5p. These findings provided a new therapeutic target for glioma.

Abstract
BACKGROUND Accurate and robust pathological image analysis for colorectal cancer (CRC) diagnosis is time-consuming and knowledge-intensive, but is essential for CRC patients' treatment. The current heavy workload of pathologists in clinics/hospitals may easily lead to unconscious misdiagnosis of CRC based on daily image analyses. METHODS Based on a state-of-the-art transfer-learned deep convolutional neural network in artificial intelligence (AI), we proposed a novel patch aggregation strategy for clinic CRC diagnosis using weakly labeled pathological whole-slide image (WSI) patches. This approach was trained and validated using an unprecedented and enormously large number of 170,099 patches, > 14,680 WSIs, from > 9631 subjects that covered diverse and representative clinical cases from multi-independent-sources across China, the USA, and Germany. RESULTS Our innovative AI tool consistently and nearly perfectly agreed with (average Kappa statistic 0.896) and even often better than most of the experienced expert pathologists when tested in diagnosing CRC WSIs from multicenters. The average area under the receiver operating characteristics curve (AUC) of AI was greater than that of the pathologists (0.988 vs 0.970) and achieved the best performance among the application of other AI methods to CRC diagnosis. Our AI-generated heatmap highlights the image regions of cancer tissue/cells. CONCLUSIONS This first-ever generalizable AI system can handle large amounts of WSIs consistently and robustly without potential bias due to fatigue commonly experienced by clinical pathologists. It will drastically alleviate the heavy clinical burden of daily pathology diagnosis and improve the treatment for CRC patients. This tool is generalizable to other cancer diagnosis based on image recognition.

Abstract
OBJECTIVE To explore the role of T-box 2 (TBX2) in esophageal squamous cell carcinomas (ESCC). PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (PCR) and Western blot (WB) assays were used to detect the expression level of TBX2 in tissues and cells. Transwell assays were conducted for determination of cell invasion and migration. RESULTS The results suggested that the TBX2 was upregulated in ESCC tissues. Further, high expression of TBX2 expression was associated with tumor size, differentiation, distant metastasis, and TNM stage. In our in-vitro study, we decreased the expression of TBX2 in ESCC cells by transfection using LipofectamineTM 3000. The results from the transwell assay suggested that the downregulation of TBX2 could significantly suppress cell migration and invasion. Besides, WB results indicated that epithelial-mesenchymal transition (EMT)-related protein expressions were also changed after transfection. CONCLUSIONS TBX2, as an oncogene, could promote the progress of ESCC by affecting the transfer ability in tumor cells.

Abstract
This study was performed to assess the effect of correcting skeletal class II malocclusion based on the application of computer-assisted design and manufacturing (CAD/CAM) cutting and drilling guides accompanied with pre-bent titanium plates. Fifty patients with skeletal class II malocclusion were recruited into this prospective randomized controlled clinical trial and assigned to two groups. Patients underwent bilateral sagittal split ramus osteotomy directed by CAD/CAM cutting and drilling guides accompanied with pre-bent titanium plates (group A) or CAD/CAM splints (group B). Postoperative assessments were performed. Differences between the virtually simulated and postoperative models were measured. Patients in both groups had a satisfactory occlusion and appearance. More accurate repositioning of the proximal segment was found in group A than in group B when comparing linear and angular differences to reference planes; however, no significant difference was revealed for the distal segment. In conclusion, CAD/CAM cutting and drilling guides with pre-bent titanium plates can provide considerable surgical accuracy for the positional control of the proximal segments in bilateral sagittal split ramus osteotomy for the correction of skeletal class II deformities.

Abstract
Abstract
Background
In cirrhosis, frailty is associated with increased risk of morbidity and mortality, including an increased risk of hospitalization. While frailty is established as a prognostic marker in cirrhosis, its impact on the progression of cirrhosis, especially in earlier stages of disease, remains unclear.
Aims
To determine the relationship between frailty and risk of cirrhosis progression, mortality, and unplanned hospitalizations in patients with cirrhosis across the spectrum of disease.
Methods
Adult patients with cirrhosis from two centers in North America and one in India were included in this retrospective review of prospectively collected data. Frailty was measured at baseline using the Liver Frailty Index (LFI), comprising grip strength, chair stands, and balance testing. Progression of cirrhosis was defined by an increase from one ordinal stage to the next using the D’Amico classification. Factors associated with progression, mortality, and hospitalizations were evaluated using multivariate competing risk regression models, with transplant as a competing risk.
Results
In total, 822 patients with cirrhosis were included. The median MELD score was 15.5 ± 6.0. Of these patients, 201 (24.5%), 488 (59.4%), and 133 (16.2%) were classified as frail, pre-frail, and robust, respectively. Over a median follow up time of 1.2 years, 60 (7.3%) patients developed progression of cirrhosis, 187 (22.7%) died, 233 (28.3%) underwent liver transplantation, and 342 (41.6%) were alive without cirrhosis progression or transplant. Adjusting for age, sex, and MELD at baseline, being frail was associated with an increased risk of progression to the next cirrhosis stage or to death as compared to being robust (HR 2.47, 95% CI 1.63–3.76, p<0.001). As a continuous variable, every increase in the LFI by 0.1 unit increased the risk of decompensation or death by 1.05-fold (95% CI 1.04–1.07, p<0.001). Similarly, patients who were frail were more likely to be hospitalized as compared to patients who were robust (HR 2.88, 95% CI 2.08–3.98, p<0.001).
Conclusions
Frailty was associated with an increased risk of cirrhosis progression or death, and hospitalization, independent of MELD at baseline. Future studies are needed to evaluate the possibility of slowing cirrhosis disease progression by reversing or preventing frailty.

Abstract
PURPOSE To evaluate the safety and efficacy of Cyberknife® (CK) for the treatment of primary or recurring thymic tumours. MATERIALS AND METHODS We retrospectively reviewed 12 patients (16 tumour lesions) with primary or recurring thymic tumours who were treated with CK between March 2008 and October 2017. Their data was stored in prospectively collected database. Kaplan-Meier method was used to calculate survival curves. RESULTS Five patients (41.7%), who had inoperable disease or refused surgery, were treated with CK initially, and 7 patients (58.3%) were treated with CK when they had recurrence diseases. The disease sites treated with CK were primary tumour site (5), regional lymph nodes (4), tumour bed (3), chest wall (2), pleura (1), and bone (1). The median target volume was 43.8 cm3 (range, 13.1-302.5cm3) for the 16 tumour lesions. The median follow-up time was 69.3 months (range, 9.7-124.8 months). The median survival time was 48.2 months, and the 5-year and 10-year OS rates were 68.2% and 45.5%, respectively. A high response rate for the tumour lesions irradiated with CK was obtained. Only one patient (8%) experienced in-field recurrence, and the 5-year local recurrence free survival was 90.9%. A case indicated that CK may induce the abscopal effect, which provides the potential to combine CK and immunotherapy. No severe radiation related toxicities were observed, and no treatment related death occurred. CONCLUSION CK treatment resulted in good outcomes, particularly local control, with minimal side effects, in highly selected patients with primary and recurring thymic tumours. More studies with larger sample are needed.

Abstract
Objectives: Giant cell arteritis (GCA) can manifest in cranial and/or extracranial arteries. We investigated the distribution of affected arteries on vascular ultrasound (VUS) among patients with new-onset or prior-onset GCA.Method: We retrospectively studied patients with either new-onset or prior-onset GCA and an abnormal VUS, from 2013 to 2017. Trained vascular technologists imaged the bilateral temporal arteries and carotid, axillary, and subclavian arteries. Vascular medicine physicians interpreted the images. Vasculitis-related abnormalities in individual vessels and their distribution (temporal artery, large artery, or both) were evaluated. Phi coefficients (φ) and Fisher's exact test were used to assess correlations among individual abnormal arteries.Results: Among 66 GCA patients, 28.8% had prior-onset GCA (median duration 17.8 months). Acute arteritis on VUS was observed in the majority of patients with both new-onset (72.3%) and prior-onset GCA (68.4%); the remainder had hyperechoic wall thickening without acute arteritis. Involvement of the temporal arteries only (45.5%) or large arteries only (34.8%) was more common than involvement of both (19.7%); this finding was similar in new-onset and prior-onset GCA. There were moderate positive correlations among temporal artery branches (φ = 0.51-0.58, p < 0.003) and among axillary and subclavian arteries (φ = 0.51-0.77, p < 0.003), and moderate negative correlations between abnormalities in the temporal and large arteries (φ = -0.46 to -0.58, p < 0.003).Conclusion: On VUS, vasculitis-related abnormalities in the temporal arteries only or large arteries only were more common than concurrent temporal and large artery abnormalities in patients with both new-onset GCA and prior-onset GCA.

Abstract
OBJECTIVE To explore the regulatory mechanism of lncRNA NORAD on proliferation and invasion of ovarian cancer cells through miR-199a-3p. PATIENTS AND METHODS Eighty-six ovarian cancer tissues and 86 tissues adjacent to cancer, human ovarian cancer cell lines SKOV3, HO-8910, A2780, OVCAR-3, and human normal ovarian epithelial cell line IOSE80 were collected. MiR-199a-3p-mimics, miR-199a-3p-inhibitor, miR-NC, si-NORAD, Sh-NORAD, and NC were transfected into HO-8910 and A2780 cells, the expression levels of lncRNA NORAD and miR-199a-3p in ovarian cancer tissues and cells were detected by qRT-PCR, and the expression levels of N-cadherin, E-cadherin, and vimentin in cells were detected by WB. Cell Counting Kit-8 (CCK-8), transwell, and cell scratch tests were used to detect proliferation, invasion, and migration of cells, and the relationship between lncRNA NORAD and miR-199a-3p was confirmed by the Dual-Luciferase reporter assay. RESULTS LncRNA NORAD was highly expressed and miR-199a-3p was lowly expressed in ovarian cancer, and the expression levels of LNCRNARAD and miR-199a-3p were negatively correlated. Cell experiments showed that inhibiting the expression of lncRNA NORAD or up-regulating the expression of miR-199a-3p could inhibit the proliferation, invasion, migration, and EMT of ovarian cancer cells, while up-regulating the expression of lncRNA NORAD or inhibiting the expression of miR-199a-3p could promote their proliferation, invasion, migration, and EMT. Dual-Luciferase reporter assay confirmed that there was a regulatory relationship between lncRNA NORAD and miR-199a-3p. CONCLUSIONS LncRNA NORAD was highly expressed in ovarian cancer tissues, while silencing lncRNA NORAD expression could inhibit the proliferation, invasion, migration, and EMT of ovarian cancer cells by regulating miR-199a-3p, which might be a new target for the diagnosis and treatment of ovarian cancer.
