Light transmission aggregometry (LTA) is the gold standard method for assessing platelet function. Recently, a new parameter called adenosine diphosphate (ADP)-induced platelet aggregation level (APAL) was developed to aid interpretation of LTA results. APAL is a score calculated based on platelet aggregation patterns upon exposure to 1 μM and 10 μM ADP and is determined using an automated coagulation analyzer. We compared APAL and VerifyNow P2Y

assay for neuroendovascular patients.

42 patients who have received antiplatelet therapy were studied. Platelet function tests were performed on CS-2400 for APAL and VerifyNow P2Y

assay was used for P2Y

reaction unit (PRU) and % inhibition.

Moderate correlations were observed between APAL and PRU (r=0.64,

<0.001) and between APAL and % inhibition (r=-0.74,

<0.001). The optimal threshold for APAL was 8.2 for PRU (threshold=240) and 8.1 for % inhibition (threshold=26%). The percentage of agreement between the above thresholds was 90.9% between PRU and APAL and 77.3% between % inhibition and APAL.

The APAL system exhibits moderate correlation with PRU and % inhibition. APAL testing is a good choice for a clinical laboratory already in possession of Sysmex CS series analyzers. In this setting, APAL testing can significantly decrease the cost of platelet function testing for patients on antiplatelet therapy.

The GLUT family has 14 members that are expressed in different tissues of the body and play essential roles in sustaining the energy demand. However, the prognostic value of the majority of GLUTs in lung cancer remains elusive and should be further evaluated in clinical studies. Thus, we investigated the prognostic data of GLUTs in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) patients through the "Kaplan-Meier (KM) plotter" database. In the current study, we found that 12 members of the GLUTs family were significantly associated with prognosis of LUAD patients, but GLUT8 was not. High expression levels of GLUT10, GLUT12, and GLUT13 were significantly associated with better overall survival (OS) in LUAD, while the other 9 members were associated with worse OS. However, GLUT family members were not correlated with OS in LUSC, although high mRNA expression level of GLUT1 tend to show an inferior OS (P=0.057). The prognostic value of GLUTs according to smoking status was also assessed. In conclusion, our study provides new insights into the prognostic values of GLUT members in LUAD, but the molecular mechanisms by which GLUTs contribute to disease aggression and the different functional roles of GLUT members need further study.

Epidermal growth factor receptor (EGFR) is one of the important targets in cancer treatment. However, EGFR inhibitors are reported to be ineffective in treating glioblastoma (GBM). In this study, we evaluated the potential mechanism of GBM resistance to EGFR inhibition.

EGFR, p38, extracellular signal-related kinase (ERK), and c-Jun N-terminal kinase (JNK) expression levels were detected by western blotting. Cell viability was evaluated by the MTT assay. Tumor necrosis factor (TNF) mRNA expression was assessed by qRT-PCR. TNF-α expression was detected by ELISA. The combined effect of EGFR inhibitor (afatinib) and TNF inhibitor (pomalidomide) was evaluated in xenograft athymic mouse model of GBM.

Upon blocking TNF, GBM sensitivity to EGFR inhibitors was observed to recover. The combination of afatinib and pomalidomide was found to effectively inhibit cell growth of EG-FR-expressing GBM. In addition, the p38/JNK/ERK pathway was activated following EGFR inhibition.

We demonstrated that GBM resistance to EGFR inhibition was mediated by the activation of TNF. The combination of EGFR inhibitor and TNF inhibitor may have potential clinical implication in treating patients with EGFR-positive GBM.

This study aimed to investigate the effects of combined activin A and Wnt3a treatment on definitive endoderm (DE) differentiation from human parthenogenetic embryonic stem cells (hPESCs).

hPESCs on human foreskin fibroblast feeder layers were induced to differentiate into DE using a combination of 50 ng/ml activin A and 25 ng/ml Wnt3a. Expression of the DE markers CXCR4, E-cadherin (ECD), Sox17, and Goosecoid (Gsc) were examined using flow cytometry and real-time quantitative PCR.

The combination of activin A and Wnt3a significantly enhanced the percentages of CXCR4

, ECD

, Sox17

, and Gsc

cells, culminating on day 2 of induction. This combined use promoted DE differentiation from hPESCs

.

Through the combination treatment using activin A and Wnt3a, DE differentiation from hPESCs culminated at 48 h, which can be regarded as the optimal time-point to induce differentiation of endodermal cells such as pancreatic, liver, and intestinal cells.

To investigate the clinical significance of microRNA-146 (miRNA-146) in patients with ulcerative colitis (UC).

The present prospective observational study included 312 UC patients from August 2015 to August 2018. All patients were divided into mild/moderate and severe groups according to their Sutherland Disease Activity Index (DAI) scores. The clinical activity index and endoscopic index were used to determine the severity of UC. Serum levels of NF-κB, CRP, IL-1β, IL-6, and TNF-α were determined by enzyme-linked immunosorbent assay (ELISA). The expression of miRNA-146a was measured using RT-qPCR.

The expression of miRNA-146a was significantly lower in both mild/moderate and severe UC patients than the healthy control, and the severe UC patients had the lowest level of miRNA-146a. All inflammatory factors were remarkably higher in severe UC patients. miRNA-146a level was negatively correlated with NF-κB, CRP, IL-1β, IL-6 and TNF-α levels. The ratio of severe UC patients was significantly higher in patients with lower miRNA-146a than in patients with higher miRNA-146a.
