Abstract
In this study, we aimed to evaluate the effect of microRNA-126 (miR-126) on neuronal apoptosis in cardiopulmonary resuscitation rats and to explore the related molecular mechanism. The expression of miR-126 in brain tissues of rats after cardiopulmonary resuscitation was measured by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR). The basic parameters of cardiopulmonary resuscitation were recorded by miR-126 mimic injection in rats after cardiopulmonary resuscitation. Hematoxylin-eosin staining was used to observe the pathological changes of hippocampus. Immunohistochemistry was used to observe the expression of p38 and caspase-3 protein. Furthermore, the expression of p38 mitogen-activated protein kinase (p38MAPK), Jun N-terminal kinase (JNK), and extracellular signal-regulated kinase 1/2 (ERK1/2) in rat hippocampus was detected by RT-qPCR and Western blot. In order to confirm whether miR-126 takes part in the p38MAPK pathway in the hippocampus of rats after cardiopulmonary resuscitation, the p38MAPK pathway inhibitor (SB203580) and activator (anisomycin) were added. The results showed overexpression of miR-126 could significantly increase the neurological function score and improve the pathological morphology of hippocampus in rats after cardiopulmonary resuscitation. miR-126 overexpression also could reduce the neuronal apoptosis, p38, and caspase-3 expression in the hippocampus. Moreover, the p38MAPK and JNK expression was downregulated and ERK1/2 expression was upregulated after miR-126 mimic injection (p < 0.05). The results of inhibition of p38MAPK pathway were consistent with those of overexpression of miR-126 (p > 0.05). This study indicated miR-126 could significantly reduce neuronal apoptosis of hippocampus in rats after cardiopulmonary resuscitation, which might be involved in the regulation of p38MAPK pathway.

Abstract
The dysregulation of hepatic gluconeogenesis is a major factor in the pathogenesis of type 2 diabetes mellitus (T2DM). Hepatic gluconeogenesis is known to be tightly regulated at the transcription/expression level. The aim of this study was to evaluate the role of the E2F8 transcription factor in glucose metabolism. Here, we found that hepatic expression levels of E2F8 were increased in db/db and high-fat-diet-induced obese mice. Adenovirus-mediated overexpression of E2F8 in primary mouse hepatocytes upregulated expression of gluconeogenic genes, including those for PGC-1α, PEPCK, and G6Pase, subsequently increasing cellular glucose output. We demonstrated that E2F8 overexpression impairs insulin sensitivity in vitro. Furthermore, knockdown of E2F8 expression increased insulin sensitivity in primary hepatocytes. In summary, these findings indicated that E2F8 is involved in gluconeogenesis and insulin resistance and may represent a new therapeutic target in T2DM prevention.

Abstract
The UCNA experiment was designed to measure the neutron β-asymmetry parameter A0 using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium were polarized via transport through a 7 T magnetic field, and then directed to a 1 T solenoidal electron spectrometer, where the decay electrons were detected in electron detector packages located on the two ends of the spectrometer. A value for A0 was then extracted from the asymmetry in the numbers of counts in the two detector packages. We summarize all of the results from the UCNA experiment, obtained during run periods in 2007, 2008–2009, 2010, and 2011–2013, which ultimately culminated in a 0.67% precision result for A0.

Abstract
MXenes are a rapidly growing family of 2D materials that exhibit a highly versatile structure and composition, allowing for significant tuning of the materials properties. These properties are, however, ultimately limited by the surface terminations, which are typically a mixture of species, including F and O that are inherent to the MXene processing. Other and robust terminations are lacking. Here, we apply high-resolution scanning transmission electron microscopy (STEM), corresponding image simulations and first-principles calculations to investigate the surface terminations on MXenes synthesized from MAX phases through Lewis acidic melts. The results show that atomic Cl terminates the synthesized MXenes, with mere residual presence of other termination species. Furthermore, in situ STEM-electron energy loss spectroscopy (EELS) heating experiments show that the Cl terminations are stable up to 750 °C. Thus, we present an attractive new termination that widely expands the MXenes' functionalization space and enables new applications.

Abstract
UNLABELLED The purpose of this research was to examine if the IL1B gene polymorphism has impact on the risk of steroid-induced ONFH in Chinese population. We found that IL1B rs1143630 decreased the SANFH's risk and IL1B rs2853550 increased the risk of steroid-induced ONFH. So, we guess that IL1B gene influences the genetic susceptibility of steroid-induced ONFH. INTRODUCTION Genetic polymorphisms in IL1B gene could be related in the pathogenesis of osteonecrosis. Discusses on the relationship between the IL1B gene and steroid-induced osteonecrosis of the femoral head (steroid-induced ONFH) is still less in Chinese Han population. So, in this research, we want to examine whether the IL1B gene polymorphism has impact on the risk of steroid-induced ONFH in Chinese population. METHODS A total of 286 steroid-induced ONFH patients and 441 controls were recruited, and seven SNPs (rs2853550, rs1143643, rs3136558, rs1143630, rs1143627, rs16944, and rs1143623) in IL1B gene were selected; unconditional logistic regression analysis was used to research the influence on the risk of steroid-induced ONFH. Functional annotations of IL1B variants were performed by RegulomeDB and HaploReg. RESULTS rs1143630 (A>C) in the IL1B gene decreased the risk of steroid-induced ONFH in the allele model (OR = 0.69, 95%CI 0.51-0.93, p = 0.014). Further genetic model analyses found that IL1B rs2853550 AG genotype increased the risk of steroid-induced ONFH compared with the people who are carriers of the IL1B rs2853550 GG genotype (OR = 1.69, 95%CI 1.16-2.46, p = 0.012). In the dominant model, IL1B rs1143630 GG-GT genotype decreased the risk of steroid-induced ONFH (OR = 0.62, 95%CI 0.44-0.87, p = 0.0051). And further haplotype analysis was performed, while the result was not significant. Using RegulomeDB and HaploReg, rs2853550 is likely to affect TF binding, any motif and DNase peak. CONCLUSIONS We guess that IL1B gene influences the genetic susceptibility of steroid-induced ONFH.

Abstract
Objective: To compare and analyze the differentially expressed plasma exosomic proteome between healthy control group (Control group) and viral myocarditis group (VMC group) to search for biomarkers that maybe used for early diagnosis of VMC. Methods: Fifty plasma samples of Control group and VMC group were collected respectively from Henan Provincial People's Hospital (from January 2016 to December 2017), and then 5 samples (1 ml) of each group were selected randomly, after exosomes extraction with ultra-centrifugation, difference gel electrophoresis (DIGE) was used to isolate the total proteins, and then the protein spots with more than 2-fold changes between VMC and Control group were picked up after the software analysis, afterward, the varied proteins were identified by MALDI-TOF/TOF mass spectrometry. Finally, the specifically related protein was selected to be verified by ELISA with the plasma exosomic samples of Control (n=40) and VMC (n=40). Results: A total of 10 varied protein spots were found including 8 up-regulated proteins and 2 down-regulated proteins between VMC and Control group. After MS analysis, the up-regulated proteins in VMC group contained KRT2, KRT5, KRT9, KRT77, KRT78, AZGP1, HP and RBP4, whereas the down-regulated ones were CD5L and C1QB. RBP4 was selected to validate by ELISA analysis, and the corresponding results showed that RBP4 was increased specifically in plasma exosomes of VMC group (P<0.05) after comparing with Control group, which was consistent with DIGE. Conclusion: Ten proteins related to VMC are detected in total, and RBP4 might serve as a potential specific biomarker for early screening and diagnosis of VMC.

Abstract
Objective The aim of this study was to summarize the evidence of health literacy and health outcomes in hypertensive patients. Methods Articles published in English were searched from six databases: MEDLINE, CINAHL, Embase, ERIC, psycINFO, and SCOPUS. The articles published up to September 2017 were included. Results Nineteen publications were included in the review. There was quality and consistent evidence that hypertensive patients with lower literacy had poorer knowledge. There was inconsistent evidence to show the relationship between health literacy and clinical outcomes, of systolic and diastolic blood pressure, and blood pressure control; behavioral outcomes, of self-care, self-efficacy, adherence; patient-physician interactions outcomes, of patient-physician communication, patient trust, involvement in decision making and other outcomes. Conclusion The person with low health literacy is likely to have poor knowledge of hypertension. However, there is insufficient evidence to suggest that health literacy is associated with outcomes of hypertension independently.

Abstract
OBJECTIVE The purpose of this study is to assess the awareness on cardiac rehabilitation (CR) in patients with coronary heart disease (CHD). METHODS Inpatients diagnosed with coronary heart disease were recruited from 3 hospitals in this study. The study employed a cardiac structured questionnaire to assess respondents' level of awareness, and bivariate to analyze the sociodemographic factors that influence the awareness on CR. RESULTS Of all 500 participants, 66.40% were male and the mean age was 62.51 ± 9.96 years. The mean score of knowledge was 44.00 ± 17.00 (score range: 0-93), and the mean level of awareness was 47.31% (awareness range: 0-100%). The highest mean level of awareness was in the reexamination subscale (98%) and the lower were in the basic information about CR program, SP optimized medication and heart rate subscale. Bivariate analysis showed that higher age was associated with less knowledge. Patients with higher education level and better income status had better knowledge. And patients who lived in rural and had no jobs had less knowledge. CONCLUSIONS This study showed low levels of awareness on CR program in CHD patients in Baoding. Therefore, the need for health education is indicated in this study to improve the awareness on CR among CHD patients.

Abstract
Inhibitors of the mechanistic target of rapamycin (mTOR) are currently used to treat advanced metastatic breast cancer. However, whether an aggressive phenotype is sustained through adaptation or resistance to mTOR inhibition remains unknown. Here, complementary studies in human tumors, cancer models and cell lines reveal transcriptional reprogramming that supports metastasis in response to mTOR inhibition. This cancer feature is driven by EVI1 and SOX9. EVI1 functionally cooperates with and positively regulates SOX9, and promotes the transcriptional upregulation of key mTOR pathway components (REHB and RAPTOR) and of lung metastasis mediators (FSCN1 and SPARC). The expression of EVI1 and SOX9 is associated with stem cell-like and metastasis signatures, and their depletion impairs the metastatic potential of breast cancer cells. These results establish the mechanistic link between resistance to mTOR inhibition and cancer metastatic potential, thus enhancing our understanding of mTOR targeting failure.
