Abstract
Since the concept of radiomics was proposed, both domestic and foreign scholars have successively carried out many scientific researches on radiomics. Domestic and foreign research teams and their corresponding research have achieved certain results in radiomics, but we still face many challenges on the clinical application of radiomics-based models. Currently radiomics is still facing challenges. We should certainly pay attention to the research hotspots, existing problems, and future perspectives of radiomics.

Abstract
BACKGROUND Osteoarthritis (OA) is characterized by chondrocyte injury. Circular RNAs (circRNAs) are involved in the pathogenesis of various diseases, including OA. The purpose of this study was to determine the potential role of circATRNL1 in OA pathology in vitro. METHODS Human chondrocytes were isolated and treated with interleukin-1 beta (IL-1β) to mimic OA in vitro. High-throughput RNA sequencing was performed to identify differentially expressed circRNAs, miRNAs and mRNAs between IL and 1β-treated chondrocytes and normal chondrocytes. The expression of circATRNL1, miR-153-3p and KLF5 was measured using quantitative real-time polymerase chain reaction (qRT-PCR). For functional analyses, cell apoptosis was assessed using a flow cytometry assay. Extracellular matrix (ECM) degradation was monitored by measuring the levels of ECM-associated proteins by Western blot. The potential target miRNAs of circATRNL1 were screened by bioinformatics analysis and verified by dual-luciferase reporter assay. RESULTS The expression of circATRNL1 was decreased in IL-1β-treated chondrocytes. CircATRNL1 overexpression ameliorated cell apoptosis and ECM degradation, which were promoted by IL-1β treatment. Mechanistic analysis revealed that circATRNL1 directly targeted miR-153-3p and that miR-153-3p could reverse the inhibitory effects of circATRNL1 overexpression on inflammatory responses, cell apoptosis and ECM degradation. KLF5 is a target of miR-153-3p. CONCLUSION Taken together, the results in this study suggested that circATRNL1 might ameliorate the development and progression of OA through regulating miR-153-3p/KLF5 axis. Our study increased the understanding of circRNAs as therapeutic targets in the treatment of OA.

Abstract
BACKGROUND/AIMS Transplantation of bone-marrow-derived mesenchymal stem cells (MSCs) promotes neural cell regeneration after spinal cord injury (SCI). Recently, we showed that suppression of microRNA-383 (miR-383) in MSCs increased the protein levels of glial cell line derived neurotrophic factor (GDNF), resulting in improved therapeutic effects on SCI. However, the overall effects of miR-383 suppression in MSCs on SCI therapy were not determined yet. Here, we addressed this question. METHODS We used bioinformatics tools to predict all miR-383-targeting genes, confirmed the functional bindings in a dual luciferase reporter assay. The effects of alteration of candidate genes in MSCs on cell proliferation were analyzed by MTT assay and by Western blotting for PCNA. The effects on angiogenesis were assessed by HUVEC assay. The effects on SCI in vivo were analyzed by transplantation of the modified MSCs into nude rats that underwent SCI. RESULTS Suppression of miR-383 in MSCs not only upregulated GDNF protein, but also increased vascular endothelial growth factor A (VEGF-A) and cyclin-dependent kinase 19 (CDK19), two other miR-383 targets. MiR-383-suppression-induced increases in CDK19 resulted in a slight but significant increase in MSC proliferation, while miR-383-suppression-induced increases in VEGF-A resulted in a slight but significant increase in MSC-mediated angiogenesis. CONCLUSIONS Upregulation of CDK19 and VEGF-A by miR-383 suppression in MSCs further improve the therapeutic potential of MSCs in treating SCI in rats.

Abstract
Background/Aims: Transplantation of bone-marrow-derived mesenchymal stem cells (MSCs) has been used to treat spinal cord injury (SCI) to enhance tissue repair and neural cell regeneration. Glial cell line derived neurotrophic factor (GDNF) is an identified neural growth and survival factor. Here, we examined whether modification of GDNF levels in MSCs may further increase the potential of MSCs in promoting neural cell regeneration and subsequently the therapeutic outcome. Methods: We examined the mRNA and protein levels of GDNF in human MSCs by RT-qPCR and Western blot, respectively. Bioinformatics analyses were done to predict microRNAs (miRNAs) that target GDNF in MSCs. The functional binding of miRNAs to GDNF mRNA was examined by a dual luciferase reporter assay. MSCs were transduced with adeno-associated virus (AAV) carrying null or antisense for miR-383 (as-miR-383), which were transplanted into nude rats that underwent SCI. The intact tissue, cavity volume, and recovery of locomotor activity were assessed. Results: MSCs expressed very low GDNF protein, but surprisingly high levels of GDNF mRNA. Bioinformatics analyses showed that miR-383 inhibited protein translation of GDNF, through binding to the 3’-UTR of the GDNF mRNA. MSCs transduced with AAV-as-miR-383 further increased the intact tissue percentage, decreased cavity volume, and enhanced the recovery of locomotor activity in nude rats that underwent SCI, compared to MSCs. Conclusions: Suppression of miR-383 may increase the therapeutic potential of human bone-marrow-derived MSCs in treating SCI via augmentation of GDNF protein levels.

Abstract
OBJECTIVE To study the correlation between single nucleotide polymorphism (SNP) of hsa-miR-124a and risk and prognosis of osteosarcoma (OS). METHODS OS patients (n = 174) hospitalized at The Second Affiliated Hospital of Harbin Medical University from January 2010 to March 2012 were selected as case group by inclusion and exclusion criteria, and healthy people (n = 150) receiving physical examination at the same duration were recruited as control group. Polymerase chain reaction-ligase detection reaction (PCR-LDR) was performed for genotyping of hsa-miR-124a rs531564. RESULTS There were significant differences in the frequency distribution of genotypes and alleles of hsa-miR-124a rs531564 in the case and control group (all P < 0.05); the individuals carrying with CG + GG genotype showed significantly decreased risk for OS. The clinical pathological characteristics were significantly different in the patients with CC genotype and CG + GG genotype, including tumor size, tumor differentiation grading, Enneking staging, operation manner, time of chemotherapy and metastasis (all P < 0.05). The 5-year survival rate of the cases with CC genotype was significantly lower than that of the ones with CG + GG genotype (P < 0.05). CG + GG genotype, Enneking staging and operation manner were independent risk factors for prognosis of OS (all P < 0.05). CONCLUSIONS CG +$ GG genotype of hsa-miR-124a rs531564 had decreased risk for OS and affected prognosis of OS.

Abstract
This study investigated the biological effects of microRNA-126 overexpression in human MG63 osteosarcoma cells. A recombinant plasmid expressing microRNA-126, pcDNA6.2-microRNA-126, was constructed and transfected into MG63 cells. Using real-time fluorogenic quantitative polymerase chain reaction, the microRNA-126 expression was measured in microRNA-126-MG63 group, Ctrl-MG63 group, and blank group. Cell proliferation, cell cycle distribution, cell migration, and invasion were analyzed using methyl thiazolyl tetrazolium assay, flow cytometer, wound-healing assay, and transwell assay, respectively. As expected, microRNA-126 expression was higher in microRNA-126-MG63 group than in Ctrl-MG63 group and blank group (both P < .05). After 48/72 hours of transfection, cell proliferation in microRNA-126-MG63 group was significantly reduced compared to blank group (both P < .05). Compared to blank group, cell population in G0/G1 stage was significantly higher in microRNA-126-MG63 group, accompanied by lower cell numbers in the S and G2/M phases and decreased proliferation index (all P < .05). Wound-healing assay showed a wider scratch width in microRNA-126-MG63 group and reduced cell migration than blank group (both P < .05). Cells overexpressing microRNA-126 exhibited reduced ADAM9 expression levels compared to other 2 groups (all P < .05), suggesting ADAM9 is a target of microRNA-126. Cell proliferation, migration, and invasion rates were reduced in microRNA-126 group after 48/72 hours of transfection, compared with blank group (all P < .05). Cotransfection of pcDNA6.2-microRNA-126 and pMIR-ADAM9 into MG63 cells led to higher cell proliferation, invasion, and migration rates, compared with transfection of pcDNA6.2-microRNA-126 alone (all P < .05). In summary, our data show that microRNA-126 inhibits cell proliferation, migration, and invasion in human osteosarcoma cells by targeting ADAM9.

Abstract
Left ventricular end-diastolic compliance (LVEDC) and transmitral flow velocities were measured in 19 patients with coronary artery disease associated with hypertension and 10 normal subjects by LV catheterization and pulsed-Doppler echocardiography. LVEDC was much lower in the patient than in the normal subjects (P less than 0.01). The data showed that abnormal Doppler diastolic function such as elevated late diastolic peak flow velocity (PVA) and decreased LVEDC occurred in the patients at the same time. In addition, the negative correlation of PVA with LVEDC observed in normal controls but not in patients suggested that in patients with impaired diastolic filling, factors other than the decreased LVEDC itself must also participate in the development of diastolic dysfunction.
