Identifying prognostic factors for osteosarcoma (OS) aids in the selection of patients who require more aggressive management. XB130 is a newly characterized adaptor protein that was reported to be a prognostic factor of certain tumor types. However, the association between XB130 expression and the prognosis of OS remains unknown. In the present study, we investigated the association between XB130 expression and clinicopathologic features and prognosis in patients suffering OS, and further investigated its potential role on OS cells in vitro and vivo. A retrospective immunohistochemical study of XB130 was performed on archival formalin-fixed paraffin-embedded specimens from 60 pairs of osteosarcoma and noncancerous bone tissues, and compared the expression of XB130 with clinicopathological parameters. We then investigate the effect of XB130 sliencing on invasion in vitro and lung metastasis in vivo of the human OS cell line. Immunohistochemical assays revealed that XB130 expression in OS tissues was significantly higher than that in corresponding noncancerous bone tissues (P=0.001). In addition, high XB130 expression more frequently occurred in OS tissues with advanced clinical stage (P=0.002) and positive distant metastasis (P=0.001). Moreover, OS patients with high XB130 expression had significantly shorter overall survival and disease-free survival (both P<0.001) when compared with patients with the low expression of XB130. The univariate analysis and multivariate analysis shown that high XB130 expression and distant metastasis were the independent poor prognostic factor.We showed that XB130 depletion by RNA interference inhibited invasion of XB130-rich U2OS cells in vitro and lung metastasis in vivo. This is the first study to reveal that XB130 overexpression may be related to the prediction of metastasis potency and poor prognosis for OS patients, suggesting that XB130 may serve as a prognostic marker for the optimization of clinical treatments. Furthermore, XB130 is the potential molecular target for OS therapy.

Background: The aim of the present study was to explore the efficacy and safety of saxagliptin in a large Chinese population with type 2 diabetes mellitus (T2DM). Methods: In all, 1423 T2DM patients from 92 research centers, either drug naïve or uncontrolled by metformin, were enrolled in this single-arm cohort study; patients were treated with saxagliptin 5 mg once daily for 24 weeks. The primary efficacy endpoint was the change from baseline in HbA1c at 24 weeks in the per-protocol analysis set. Secondary endpoints included the proportion of patients achieving HbA1c <7% and changes from baseline in fasting plasma glucose (FPG) and 2-h postprandial plasma glucose (PPG) concentrations at 24 weeks. Safety endpoints included adverse events (AEs) and the incidence of hypoglycemia. Results: Among 1210 patients in the per-protocol analysis set, mean HbA1c, FPG and 2-h PPG decreased by 1.61±0.04%, 0.55±0.07 mmol/L, and 2.83±0.27 mmol/L, respectively, at week 24. The proportion of patients achieving HbA1c <7% was 44.1%. No new (previously unreported) AEs occurred. The incidence of serious AEs and hypoglycemia was low (1.8% and 1.2%, respectively). There were no significant differences in efficacy endpoints in subgroup analyses by age, creatinine clearance, body mass index, or treatment background. In elderly patients (≥65 years) and those with mild renal impairment (50

To explore whether lidocaine has the synergistic effect with pingyangmycin (PYM) in the venous malformations (VMs) treatment.The mouse spleen was chosen as a VM model and injected with different concentration of lidocaine or PYM or jointly treated with lidocaine and PYM. After 2, 5, 8 or 14 days, the mouse spleen tissues were acquired for hematoxylin-eosin (HE) staining, transmission electron microscopy (TEM) analysis, TUNEL assay and quantitative RT-PCR analysis to examine the toxicological effects of lidocaine and PYM on splenic vascular endothelial cells.0.4% of lidocaine mildly promoted the apoptosis of endothelial cells, while 2 mg/ml PYM significantly elevated the apoptotic ratios. However, the combination of 0.2% lidocaine and 0.5 mg/ml PYM notably elevated the apoptotic ratios of splenic cells and severely destroyed the configuration of spleen, compared to those of treatment with 0.5 mg/ml PYM alone.Lidocaine exerts synergistic effects with PYM in promoting the apoptosis of mouse splenic endothelial cells, indicating that lidocaine possibly promotes the therapeutic effects of PYM in VMs treatment via synergistically enhancing the apoptosis of endothelial cells of malformed venous lesions.

Long term video game players (VGPs) exhibit superior visual and motor skills compared with non-video game control subjects (NVGCs). However, the neural basis underlying the enhanced behavioral performance remains largely unknown. To clarify this issue, the present study compared the whiter matter integrity within the corticospinal tracts (CST), the superior longitudinal fasciculus (SLF), the inferior longitudinal fasciculus (ILF), and the inferior fronto-occipital fasciculus (IFOF) between the VGPs and the NVGCs using diffusion tensor imaging. Compared with the NVGCs, voxel-wise comparisons revealed significantly higher fractional anisotropy (FA) values in some regions within the left CST, left SLF, bilateral ILF, and IFOF in VGPs. Furthermore, higher FA values in the left CST at the level of cerebral peduncle predicted a faster response in visual attention tasks. These results suggest that higher white matter integrity in the motor and higher-tier visual pathways is associated with long-term video game playing, which may contribute to the understanding on how video game play influences motor and visual performance.

Greater impulse and risk-taking and reduced decision-making ability were reported as the main behavioral impairments in individuals with internet gaming disorder (IGD), which has become a serious mental health issue worldwide. However, it is not clear to date how the risk level modulates brain activity during the decision-making process in IGD individuals. In this study, 23 adolescents with IGD and 24 healthy controls (HCs) without IGD were recruited, and the balloon analog risk task (BART) was used in a functional magnetic resonance imaging experiment to evaluate the modulation of the risk level (the probability of balloon explosion) on brain activity during risky decision making in IGD adolescents. Reduced modulation of the risk level on the activation of the right dorsolateral prefrontal cortex (DLPFC) during the active BART was found in IGD group compared to the HCs. In the IGD group, there was a significant negative correlation between the risk-related DLPFC activation during the active BART and the Barratt impulsivity scale (BIS-11) scores, which were significantly higher in IGD group compared with the HCs. Our study demonstrated that, as a critical decision-making-related brain region, the right DLPFC is less sensitive to risk in IGD adolescents compared with the HCs, which may contribute to the higher impulsivity level in IGD adolescents.

This study was to clarify the regulated effects of TNF- -308G/A polymorphism on TNF- and investigate the relationship of -308G/A polymorphisms with diabetic nephropathy (DN) susceptibility.86 DN patients and 94 healthy individuals were enrolled in our study. Polymerase chain reaction-sequence specific primer (PCR-SSP) detection technology was used to testify single nucleotide polymorphism (SNP) of TNF- gene. Enzyme-linked immunosorbent assay (ELISA) was used to measure the content of TNF- protein. Odds ratio (OR) with 95% CI were used to evaluate the association of TNF- -308G/A polymorphism and DN susceptibility.The level of TNF- protein was much higher in DN patients compared to that of controls (P<0.05). For TNF- -308G/A, G/A genotype could increase the risk for DN (OR=2.15, 95% CI=1.08-4.30). Moreover, a allele frequency was found higher in cases compared with controls, which suggested that A allele served as an genetic-susceptibility factor for DN (OR=1.89, 95% CI=1.10-3.26). Further analysis indicated that level of TNF- for individuals with mutant genotype (GA and AA) were higher than that of individuals with wild genotype (P<0.05). However, AA genotype showed no effects on DN susceptibility (OR=2.08, 95% CI=0.56-7.33).TNF--308G/A polymorphism was associated with expression level of TNF- and served as an genetic-susceptibility factor for DN.
