Abstract
Abstract
Background
Atherosclerotic plaque hypoxia is detrimental for macrophage function. Prolyl hydroxylases (PHDs) initiate cellular hypoxic responses, possibly influencing macrophage function in plaque hypoxia. Thus, we aimed to elucidate the role of myeloid PHDs in atherosclerosis.
Methods
Myeloid specific PHD knockout (PHDko) mice were fed high cholesterol diet for 6–12 weeks to induce atherosclerosis. Plaque parameters, e.g. plaque size and macrophage content, were analyzed. Bulk and single cell RNA sequencing was performed on PHD2 BMDMs and plaque macrophages, respectively.
Results
Aortic root plaque size was augmented 2.6fold in PHD2cko, and 1.4-fold in PHD3ko, but not in PHD1ko mice compared to controls. Macrophage apoptosis was promoted in PHD2cko and PHD3ko mice in vitro and in vivo, via the HIF1α/BNIP3 axis. Bulk and single cell RNA data of PHD2cko bone-marrow-derived macrophages (BMDM) and plaque macrophages, respectively, confirmed these findings and were validated by siRNA silencing. Human plaque BNIP3 mRNA associated with plaque necrotic core, suggesting similar adverse effects. Further, PHD2cko plaques displayed enhanced fibrosis, independent of macrophage MMP activity, collagen secretion or proliferation and of SMC collagen production, or proliferation. Rather, PHD2cko BMDMs enhanced fibroblast collagen secretion in a paracrine manner. Nichenet in silico analysis of macrophage-fibroblast communication predicted SPP1 signaling as regulator, in line with enhanced plaque SPP1 protein content, and SPP1 mRNA in TREM2-foamy plaque macrophages, but not in neutrophils.
Conclusion
Myeloid PHD2cko and PHD3ko enhanced plaque growth, macrophage apoptosis, and PHD2cko activated paracrine collagen secretion by fibroblasts.

Abstract
Many studies have associated altered intestinal bacterial communities and non-alcoholic fatty liver disease, but the putative effects are inconclusive. The purpose of this network meta-analysis (NMA) was to evaluate the effects of probiotics, prebiotics, and synbiotics on non-alcoholic fatty liver disease through randomised intervention trials. Literature searches were performed until March 2020. For each outcome, a random NMA was performed, the surface under the cumulative ranking curve (SUCRA) was determined. A total of 22 randomised trials comparing prebiotic, probiotic, and synbiotic treatments included 1301 participants. Considering all seven results (aspartate aminotransferase, alanine aminotransferase, body mass index, weight, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol) together, the highest SUCRA values are probiotics (94%), synbiotics (61%) and prebiotics (56%), respectively. NMA results provide evidence that probiotics, prebiotics, and synbiotics can alleviate non-alcoholic fatty liver disease. However, due to the lack of high-quality randomised trials, this research also has some limitations.

Abstract
OBJECTIVE To investigate the efficacy and safety of intravascular ultrasound (IVUS)-guided rotational atherectomy (RA) combined with cutting balloon for pretreatment of severe calcified lesions in the coronary artery before stent placement. METHODS A total of 120 patients with severe coronary artery calcifications detected by IVUS that required percutaneous coronary intervention (PCI) were recruited from our hospital between January, 2016 to January, 2019. The patients were randomized into two groups for pretreatment of the lesions with semicompliant balloon (SB group, 60 cases) or RA combined with CB (RA+CB group, 60 cases), and drug-eluting stents were implanted after the procedure. The immediate success rate of PCI, vascular parameters detected by IVUS after PCI, and the rates of residual stenosis < 10% were compared between the two groups. The incidences of intraoperative complications and major adverse cardiac events (MACE) within 24 months after the surgery were also observed in the two groups. RESULTS The immediate success rate was significantly higher in RA+CB group than in SB group (P=0.032). After pretreatment and stent placement, the minimum stent lumen diameter (P=0.035), minimum stent lumen cross-sectional area (P=0.029), immediate lumen acquisition, immediate lumen cross-sectional area acquisition and the rate of residual stenosis < 10% were all significantly higher in RA+CB group than in SB group (P < 0.001). The patients in RA+ CB group showed obviously less residual stenosis of lumen cross-sectional area than those in SB group after the surgery (χ2= 7.859, P=0.005). The incidences of intraoperative complications (χ2=5.997, P=0.014) and MACE within 24 months after the operation (χ2=4.285, P=0.038) were significantly lower in RA+CB group than in SB group. CONCLUSION For patients with severe coronary artery calcifications eligible for PCI, RA combined with CB angioplasty can significantly improve the success rate of immediate PCI, expand the lumen diameter and cross-sectional area of the stent after PCI, enhance immediate lumen gain, and reduce the incidence of intraoperative complications and MACE after the operation.

Abstract
To determine whether curcumin (Cur) can treat mice with experimentally-induced colitis by regulating follicular helper T cells (Tfh) and follicular regulatory T cells (Tfr) by inhibiting interleukin (IL)-21. In this study, 40 male C57BL/6 mice were randomly grouped into four groups, i.e., normal, trinitrobenzene sulfonic acid (TNBS), TNBS + curcumin, and TNBS + anti-IL-21. Mice with experimental colitis were induced by 100 mg/kg TNBS. The mice in the TNBS + Cur group were treated with 100 mg/kg curcumin for seven days, and mice in the TNBS + anti-IL-21 group were treated with anti-IL-21 (150 μg/mouse) once per week, intraperitoneally, starting on the second day after establishing the experimental colitis model. On day eight, the therapeutic effect of curcumin was evaluated by colon mucosa damage index (CMDI), histological examination, and disease activity index (DAI). Furthermore, the number of CD4 + CXCR5 + PD-1 + Tfh and CD4 + CXCR5 + FoxP3 + Tfr cells were measured by flow cytometry. The mRNA and protein expression of IL-21, Bcl-6, FOXP3, ICOS, and PD-1 in colonic mucosa was detected by reverse transcription polymerase chain reaction and the Western blot technique. Compared with the TNBS group, the DAI, CMDI, histological score, the number of CD4 + CXCR5 + PD-1 + Tfh cells, the expression of IL-21, Bcl-6, ICOS, and PD-1 were significantly decreased in the TNBS + curcumin group and TNBS + anti-IL-21 group; body weight, number of CD4 + CXCR5 + FoxP3 + Tfr cells, and the expression of FoxP3 were observably elevated in the TNBS + curcumin group (all P < 0.05). Curcumin may have a potential therapeutic effect on mice with colitis treated experimentally through regulation of the balance of Tfh and Tfr cells via inhibiting the synthesis of IL-21.

Abstract
OBJECTIVE To investigate the value of quantitative detection of ITGA4 and SFRP2 gene methylation in stool DNA for the early diagnosis and prognostic evaluation of colorectal tumors. OBJECTIVE Real-time PCR was used for quantitative assessment of ITGA4 and SFRP2 gene methylation levels in stool samples of 85 patients with colorectal cancer, 65 patients with colorectal adenoma and 40 healthy subjects. OBJECTIVE The 3 groups were comparable for age and gender composition. Methylated ITGA4 and SFRP2 promoters were detected in 48.2% and 62.4% of patients with colorectal cancer, respectively, with a combined positivity of 81.2%. ITGA4 and SFRP2 promoter methylation was detected in 23.1% and 43.1% of patients with colorectal adenoma, respectively, with a combined positivity of 69.2%. The positivity rates of ITGA4 and SFRP2 methylation were significantly higher in patients with colorectal cancer than in those with colorectal adenoma (P < 0.001; P= 0.001) and healthy subjects (P < 0.001; P < 0.001). In colorectal cancer group, ITGA4 and SFRP2 promoter methylation levels were correlated with postoperative tumor recurrence in colorectal cancer group, and the relapse-free survival rate was significantly lower in positive patients for ITGA4 and SFRP2 promoter methylation than in the negative patients (P=0.0002; P=0.007). Multivariate analysis with the COX proportional hazard regression model showed that methylation of ITGA4 and SFRP2 gene promoters (P=0.01) and the degree of tumor differentiation (P=0.03) were associated with the recurrence of colorectal cancer, and were independent risk factors for the recurrence of colorectal cancer. OBJECTIVE Combined detection of ITGA4 and SFRP2 gene methylation levels in stool DNA can improve the early diagnosis rate of colorectal tumor. ITGA4 and SFRP2 promoter methylation and the degree of tumor differentiation are independent risk factors for colorectal cancer recurrence.

Abstract
Aims Atherosclerotic plaque hypoxia is detrimental for macrophage function. Prolyl hydroxylases (PHDs) initiate cellular hypoxic responses, possibly influencing macrophage function in plaque hypoxia. Thus, we aimed to elucidate the role of myeloid PHDs in atherosclerosis. Methods and results Myeloid-specific PHD knockout (PHDko) mice were obtained via bone marrow transplantation (PHD1ko, PHD3ko) or conditional knockdown through lysozyme M-driven Cre recombinase (PHD2cko). Mice were fed high cholesterol diet for 6–12 weeks to induce atherosclerosis. Aortic root plaque size was significantly augmented 2.6-fold in PHD2cko, and 1.4-fold in PHD3ko compared to controls but was unchanged in PHD1ko mice. Macrophage apoptosis was promoted in PHD2cko and PHD3ko mice in vitro and in vivo, via the hypoxia-inducible factor (HIF) 1α/BNIP3 axis. Bulk and single-cell RNA data of PHD2cko bone marrow-derived macrophages (BMDMs) and plaque macrophages, respectively, showed enhanced HIF1α/BNIP3 signalling, which was validated in vitro by siRNA silencing. Human plaque BNIP3 mRNA was positively associated with plaque necrotic core size, suggesting similar pro-apoptotic effects in human. Furthermore, PHD2cko plaques displayed enhanced fibrosis, while macrophage collagen breakdown by matrix metalloproteinases, collagen production, and proliferation were unaltered. Instead, PHD2cko BMDMs enhanced fibroblast collagen secretion in a paracrine manner. In silico analysis of macrophage-fibroblast communication predicted SPP1 (osteopontin) signalling as regulator, which was corroborated by enhanced plaque SPP1 protein in vivo. Increased SPP1 mRNA expression upon PHD2cko was preferentially observed in foamy plaque macrophages expressing ‘triggering receptor expressed on myeloid cells-2’ (TREM2hi) evidenced by single-cell RNA, but not in neutrophils. This confirmed enhanced fibrotic signalling by PHD2cko macrophages to fibroblasts, in vitro as well as in vivo. Conclusion Myeloid PHD2cko and PHD3ko enhanced atherosclerotic plaque growth and macrophage apoptosis, while PHD2cko macrophages further activated collagen secretion by fibroblasts in vitro, likely via paracrine SPP1 signalling through TREM2hi macrophages.

Abstract
OBJECTIVE Osteosarcoma (OS) is a frequent bone malignancy. Long non-coding RNA myocardial infarction associated transcript (MIAT) has been reported to be involved in the development of human cancers, including OS. However, the mechanism underlying MIAT in OS progression remains largely unclear. PATIENTS AND METHODS The expression levels of MIAT and sineoculis homeobox homolog 1 (SIX1) in OS tissues and cells were detected by quantitative real-time polymerase chain reaction and Western blot. Cell viability, apoptosis, migration and invasion of OS cells were determined by MTT, flow cytometry and trans-well assays, respectively. The target interaction among MIAT, miR-141-3p and SIX1 was analyzed by bioinformatics analysis and luciferase reporter assay. Phosphatidylinositide 3-kinases (PI3K)/protein kinase B (AKT) pathway was evaluated by Western blot. RESULTS MIAT and SIX1 expression levels were enhanced in OS tissues and cells. Knockdown of MIAT or SIX1 repressed cell viability, migration and invasion but promoted apoptosis in OS cells. Moreover, overexpression of SIX1 reversed the inhibitive role of MIAT silence in OS progression. Furthermore, MIAT could increase SIX1 expression by competitively sponging miR-141-3p. Besides, inhibition of MIAT blocked PI3K/AKT pathway by decreasing SIX1 in OS cells. CONCLUSIONS MIAT silence suppresses OS progression through inactivating PI3K/AKT signaling by sponging miR-141-3p to regulate SIX1, indicating a novel target for the treatment of OS.

Abstract
Objective: To explore the expression of circ-KEL in patients with acute myeloid leukemia (AML) and the effect and mechanism of circ-KEL on leukemic cells. Methods: The expression of circ-KEL was detected by quantitative real-time polymerase chain reaction in bone marrow mononuclear cells collected from 116 patients with AML and 40 healthy donors. The correlation of circ-KEL expression with the clinical characteristics of patients with AML was further systematically analyzed. The modulations among circ-KEL, miR-335-5p, and LRG1 were predicted through bioinformatics analysis and validated by dual luciferase assay. Cell proliferation and apoptosis were detected using CCK8 and flow cytometry. Results: The expression of circ-KEL was significantly elevated in patients with AML compared with the healthy controls (Relative expression level, -Δct, AML: -7.117±1.831; control: -8.669±1.771, P<0.001) . Moreover, patients with high circ-KEL expression have significantly worse overall survival. The level of circ-KEL in patients with AML was downregulated after chemo-treatment. In addition, circ-KEL could serve as the sponge of miR-335-5p and regulate LRG1. Bioinformatics analysis showed that miR-335-5p correlates with good prognosis and was negatively associated with LRG1. LRG1 could promote cell proliferation and inhibit cell apoptosis. Our results also exhibited the higher expression of LRG1 in patients with AML. Moreover, circ-KEL exerted functional effects via sponging miR-335-5p and regulating LRG1. Conclusion: circ-KEL expresses highly in patients with AML and correlates with poor prognosis, suggesting its important role in the genesis and progress of AML.

Abstract
OBJECTIVE Recently, long noncoding RNAs (lncRNAs) have attracted much attention for their roles in tumor progression. The aim of this study was to investigate the exact role of lncRNA UCA1 in the development of thyroid cancer (TC) and to explore the possible underlying mechanism. PATIENTS AND METHODS UCA1 expression in both TC cells and tissues was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Colony formation assay, cell proliferation, and transwell assay were conducted in vitro. Subsequent luciferase reporter gene assay was applied to investigate the underlying mechanism. Furthermore, the function of UCA1 in vivo was monitored as well. RESULTS UCA1 expression level in TC samples was significantly higher than that of corresponding normal tissues. After UCA1 was knocked down in vitro and in vivo, the proliferation, migration, and invasion of TC cells were significantly inhibited. Moreover, the expression of miR-497-3p was repressed after the knockdown of UCA1. Furthermore, miR-497-3p was directly targeted by UCA1. CONCLUSIONS Knockdown of UCA1 could inhibit TC cell proliferation and metastasis via sponging miR-497-3p. Our findings might offer a new therapeutic intervention for TC patients.

Abstract
The design and fabrication of a vertically stacked red-green-blue (RGB) light-emitting diode (LED) with novel, to the best of our knowledge, wavelength-selective distributed Bragg reflectors (DBRs) are demonstrated. The two DBRs are optimized to achieve selective reflectance in the RGB spectral region through theoretical calculations and simulation modeling. The insertion of optimal DBRs into the stack structure can effectively reflect downward emission from the upper chip without filtering the emission from the lower chips, thereby increasing the luminous efficiency for white emission with a color temperature range of 3000-8000 K by 1.6-7.4%. The optical performances of stacked devices with and without DBRs are thoroughly studied, verifying the effectiveness of the proposed wavelength-selective DBR structure.

Abstract
OBJECTIVE Tongue cancer is a common malignant tumor in the oral and maxillofacial region, most of which is squamous cell carcinoma. Cisplatin (DDP) is one of the chemotherapy drugs for patients with tongue squamous cell carcinoma (TSCC). However, DDP resistance has become a major obstacle to its clinical application. Our study aimed to investigate the effects of long non-coding RNA (lncRNA) KCNQ1 overlapping transcript 1 (KCNQ1OT1) on DDP resistance of tongue cancer and the underlying mechanism. PATIENTS AND METHODS The levels of KCNQ1OT1, miR-124-3p, and tripartite motif containing 14 (TRIM14) were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The maximum size of tumor (MTS) assay was used to detect the cell survival rates. Furthermore, the cell proliferation was detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. Transwell assay was performed to detect the cell migration and invasion. Western blot assay was used to detect the protein levels of Vimentin, N-cadherin, E-cadherin, and TRIM14. The functional targets of KCNQ1OT1 and miR-124-3p, miR-124-3p and TRIM14 were predicted by starBase 3.0 and TargetScan. The relationship between KCNQ1OT1 and miR-124-3p was confirmed by Dual-Luciferase reporter assay, RNA immunoprecipitation (RIP) and RNA pull-down. Further, the relationship between miR-124-3p and TRIM14 was verified by Dual-Luciferase reporter assay. Animal experiment revealed the effect of KCNQ1OT1 on DDP resistance of tongue cancer cells in vivo. RESULTS KCNQ1OT1 was upregulated in DDP-resistant tongue cancer tissues and cells, and mainly expressed in cytoplasm. Functionally, the knockdown of KCNQ1OT1 inhibited the survival rate, proliferation, migration, invasion, and EMT of the DDP-resistant tongue cancer cells. Of note, miR-124-3p acted as a target of KCNQ1OT1 and KCNQ1OT1 could reduce the expression of miR-124-3p. Moreover, miR-124-3p targeted TRIM14 and the downregulation of TRIM14 reduced the DDP resistance of tongue cancer cells. Importantly, KCNQ1OT1 regulated the TRIM14 expression by targeting miR-124-3p. Furthermore, KCNQ1OT1 knockdown reduced the DDP-resistant tumor growth and weight through the miR-124-3p/TRIM14 axis in vivo. CONCLUSIONS LncRNA KCNQ1OT1 promotes the DDP resistance of tongue cancer by sponging miR-124-3p to regulate TRIM14 expression.

Abstract
Abstract
Purpose
Cardiac amyloidosis (CA) is a major cause of mortality in patients with amyloidosis because it leads to heart failure and lethal arrhythmia. The present study was aimed to evaluate left ventricular (LV) global myocardial deformation in patients with CA of transmural late gadolinium enhancement (LGE) using tissue tracking MRI.
Materials and methods
Thirty-nine patients with CA, confirmed by cardiac MRI, and a biopsy of at least one involved organ were enrolled. According to LV ejection fraction (LVEF), they were divided into reduced LVEF (CArEF) and preserved EF (CApEF) groups. Thirty-nine normal controls were recruited (NC). Tissue tracking analysis was done based on cine MRI sequences. LV global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were computed.
Results
GLS [CArEF vs. CApEF vs. NC: (−5.82±2.42) % vs. (−8.44±4.15) % vs. (−14.74±2.93)%], GCS [CArEF vs. CApEF vs. NC: (−9.47±2.96) % vs. (−15.01±1.81) % vs. (−19.86±2.30) %], and GRS [CArEF vs. CApEF vs. NC: (11.37±4.68) % vs. (20.61±6.27) % vs. (39.02±8.98) %] were all reduced in the CArEF and CApEF groups compared with healthy control subjects (all P<0.01). GCS and GRS in the CArEF group were reduced compared with the CApEF group (P<0.01). GLS, GCS, and GRS were also strongly correlated with LVEF (r=−0.77, −0.88, and 0.83, respectively; P<0.01). Furthermore, the optimal cutoff values to predict LVEF reduction were −9.31% (sensitivity 88%, specificity 97%) for GLS, −14.13% (sensitivity 96%, specificity 97%) for GCS, and 20.11% (sensitivity 90%, specificity 97%) for GRS.
Conclusion
MRI-based LV global deformation parameters could be a useful method to assess LV myocardial systolic function and predict LVEF reduction in patients with CA of transmural enhancement on LGE. The differences of GCS and GRS between the CArEF and CApEF groups may also reflect preserved contractile function of the mid- or/and subepicardial myocardium.
