Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease, resulting not only in liver dysfunction, glucose and lipid metabolism disorder, but also in neuropsychiatric damage. In the present study, a NAFLD rat model was established via feeding of a high-fat diet, and behaviour was observed via the open field test (OFT), the sucrose preference test (SPT), the elevated plus maze (EPM), the forced swimming test (FST) and the Morris water maze (MWM). The plasma concentrations of alanine aminotransferase (ALT), glucose, free fatty acid (FFA), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were detected using chemiluminescence technique. The plasma levels of nesfatin-1, leptin and insulin were measured via enzyme-linked immunosorbent assay, and the protein expressions of p-glycogen synthase kinase-3β (GSK-3β), GSK-3β, p-β-catenin, β-catenin, cyclinD and copine 6 in the hippocampus and prefrontal cortex (PFC) were detected using western blotting. After 4 consecutive weeks of feeding with a high-fat diet, the rats showed obesity; increased plasma concentrations of ALT, glucose, FFA, TC, TG, HDL-C and LDL-C; decreased plasma levels of leptin and insulin; and inflammation and mild hepatocyte steatosis in the liver. Although there was no significant difference between groups with regard to performance in the OFT, EPM or FST, the NAFLD rats showed a decreased sucrose preference index in the SPT and impaired learning and memory in the MWM task. Moreover, the present study provides the first evidence of an increased plasma nesfatin-1 concentration in NAFLD rats, which was significantly correlated with plasma lipid concentrations and behavioural performance. Furthermore, copine 6 and p-β-catenin protein expression decreased and p-GSK-3β increased in the hippocampus and PFC of NAFLD rats. These results suggest that consuming of a high-fat diet for 4 consecutive weeks could successfully induce a NAFLD rat model. More importantly, these results provide the first evidence that impaired learning and memory in NAFLD rats was, at least partly, associated with increased plasma nesfatin-1 concentration and decreased copine 6 expression in the hippocampus and PFC. © 2017 British Society for Neuroendocrinology

Objective: To explore the value of Oxford acute severity of illness score in evaluating the severity and prognosis of critical illness patients. Methods: All adult patients admitted to the Department of Critical Care Medicine from August 2012 to July 2014 were retrospectively analyzed. The severity in survivors and non-survivors was evaluated by using Oxford acute severity of illness score and APACHE III score, and then statistic analysis were performed. Results: Of 470 patients, 321 (68.297%) were male, the range of age and (x-± s) age were 18 to 97 years and (59 ± 18) years respectively, and 123 patients (26.170%) were in non-survivors group and 347 patients in survivors group. The area under the ROC of Oxford acute severity of illness score was 0.760 (95% CI; 0.712-0.808, P < 0.001), and Youden index was biggest when Oxford acute severity of illness score was 30.5. The area under the ROC of APACHE III score was 0.844 (95% CI; 0.806-0.882, P < 0.01), and Youden index was biggest when APACHE III score was 70.5. Mortality was high (above 70%) as Oxford acute severity of illness score increased (> 40), and Spearman r was 0.976 (P<0.01). Conclusions: Oxford Acute Severity of Illness Score was useful to evaluating the severity and prognosis of critical illness patients and it was easy in clinical practice.

This multi-centered study was designed to evaluate the biological effects of exposure to antineoplastic drugs (ADs) at PIVAS (Pharmacy Intravenous Admixture Service) across ten Chinese hospitals. 8-hydroxy-2-deoxyguanosine (8-OHdG) was used as a biomarker of DNA oxidative damage and lymphocyte apoptosis assays using peripheral lymphocyte cells were used to detect primary DNA damage. The mutagenicity activity was estimated with the Ames fluctuation test. 158 exposed and 143 unexposed workers participated in this study. The urinary 8-OHdG/Cr concentrations of the exposed group was 22.0517.89ng/mg Cr, which was significantly higher than controls of 17.3613.50ng/mg Cr (P<0.05). The rate of early lymphocyte apoptosis was slightly increased in exposed group than that of the control group (P=0.087). The mutagenic activity was significantly higher in the exposed group relative to the control group (P<0.05). Moreover, while no statistically significant difference was observed, higher concentrations of 8-OHdG/Cr in urine and an early lymphocyte apoptosis rate were found in exposed group II as compared to exposed group I. In addition, a significant correlation between early lymphocyte apoptosis and exposure time to ADs was also observed (P<0.05). In conclusion, our study identified elevated biomarkers in PIVAS workers exposed to ADs. However whether these findings could lead to increased incidence of genotoxic responses remains to be further investigated.

Objective: To explore the automated immunostainer screening anaplastic lymphoma kinase (ALK) gene fusion non-small cell lung cancer (NSCLC) and clinicopathological characteristics of the molecular subtype lung cancers. Methods: Five hundred and sixty-six cases of NSCLC were collected over a 16 month period. The test for ALK was performed by Ventana automated immunostainer with anti-ALK D5F3. The histological features, treatment and outcome of patients were assessed. Results: Thirty-eight cases (6. 7%, 38/566) of NSCLC showed ALK gene fusion. The frequency of ALK gene fusion was higher in male (7. 1%, 25/350) than that in female (6.0%, 13/216) patients, but not achieving statistical significance (X2 =0. 270, P = 0. 604). ALK + NSCLC was more significantly more frequent in patients =≤ 60 years (9. 9%, 28/282) than >60 years (3. 5%, 10/284) of age. Histologically, the ALK + NSCLCs were mostly adenocarcinoma (81. 6%, 31/38), among which eighteen cases were solid predominant subtype with mucin production; nine cases were acinar predominant subtype; one case was papillary predominant subtype and three cases were invasive mucinous adenocarcinoma. The ALK + non-adenocarcinoma included three cases of squamous cell carcinoma, three cases of adenosquamous carcinoma and one case of pleomorphic carcinoma. Among the ALK + NSCLC patients, the number of non/light cigarette smokers (86. 8%, 33/38) was more than that of heavy smokers. Twenty-nine cases were stages III and IV; twenty-nine cases showed lymph node metastasis; twenty cases showed metastases mostly to brain and bone; and one case showed EGFR gene mutation coexisting with ALK gene fusion. Twelve of fifteen patients received crizotinib therapy and remained stable. Conclusions: NSCLC with ALK gene rearrangement shows distinctive clinical and histological features. Ventana-IHC may be a feasible and valid technique for detection of ALK rearrangement in NSCLC.

microRNAs (miRNAs) have been hypothesized to function as oncogenes or tumor suppressors by targeting specific cancer-related genes. Previous studies have reported that miR-223 may serve as a tumor suppressor in a number of cancer types, however, knowledge of its targets in non-small cell lung cancer (NSCLC) remains limited. In the current study, miR-223 was found to inhibit cell proliferation in vitro by CCK-8 assay, growth curves and an anchorage-independent growth assay in a Lewis lung carcinoma (LLC) cell line. miR-223 transfection in the LLC cells was observed to significantly inhibit migration and invasion, induce G2/M arrest and decrease the expression levels of Sca-1, a marker of murine stem cells. In addition, miR-223 transfection markedly suppressed AKT and ERK signaling, as well as insulin-like growth factor-1 receptor (IGF-1R)-mediated downstream signaling, pathways that are crucial for cell proliferation and invasion in NSCLC cells. Analyses in C57BL/6 mice demonstrated that miR-223 suppresses tumorigenicity in vivo. Using a luciferase activity assay and western blot analysis, IGF-1R and cyclin-dependent kinase 2 (CDK2) were identified as direct targets of miR-223. In the present study, novel cancer-related targets of miR-223 were identified and verified in a LLC cell line, indicating that miR-223 functions as a tumor suppressor, which may fine-tune the activity of the IGF-1R pathway in lung cancer. Therefore, increasing miR-223 expression may provide a novel approach for the treatment of NSCLC.

There is increasing evidence that cancer stem cells contribute to the initiation and propagation of many tumor. Therefore, to find out and identify the metastatic tumor stem-like cells in Lewis lung cancer cell line (LLC), the expression of CXCR4 was measured in LLC by flow cytometry and observed by laser scanning confocal microscope (LSCM). After the CXCR4 + LLC cell was isolated from LLC by magnetic cell sorting, its properties were evaluated by their tumorigenic and metastatic potentials. CXCR4 + cells were counted for 0.18% of the total number of LLC, and immunofluorescent staining cells were identified by LSCM. CXCR4 + LLC suspension cultured in a serum-free medium, cell spheres expressed a high level of Sca-1. The chemotherapy sensitivity to cisplatin of CXCR4 + LLC was lower than that of CXCR4 - LLC. The expression of ABCG2 and IGF1R mRNA in CXCR4 + LLC was higher than that in CXCR4 - LLC (P < 0.01). Most of CXCR4 + LLC cells were close to vascular endothelial cells, aberrant vasculature around it was forming. The expression of VEGF and MMP9 mRNA in CXCR4 + LLC was higher than that in CXCR4 - LLC (P < 0.05), the microvessel density (MVD) of CXCR4 + subsets growing were higher than that of CXCR4 - subsets growing tumor tissue (P < 0.01). The tumor size, volume, and metastatic foci in the lungs of CXCR4 + LLC was significantly higher than that in CXCR4 - LLC (P < 0.001). Similarly, elevated expression of MMP9 and VEGF was also positively associated with CXCR4 + LLC. Our results demonstrated that CXCR4 + cells from Lewis lung carcinoma cell line exhibit cancer metastatic stem cell characteristics. © 2011 Springer Science+Business Media, LLC.

Lung cancer is the major cause of cancer-related deaths worldwide, thus developing effective methods for its early diagnosis is urgently needed. In recent years, microRNAs (miRNAs, miR) have been reported to play important roles in carcinogenesis and have become potential biomarkers for cancer diagnosis and treatment. Molecular beacon (MB) technology is a universal technology to detect DNA/RNA expression in living cells. As a natural polymers, chitosan (CS) nanoparticles could be used as a carrier for safe delivery of nucleic acid. In this study, we developed a probe using nanoparticles of miR-155 MB self assembled with CS (CS-miR-155 MB) to image the expression of miR-155 in cancer cells. Hybridization assay showed that the locked nucleic acid (LAN) modified miR-155 MB could target miR-155 effectively and sensitively. The miR-155 MB self-assembly with CS nanoparticles formed stable complexes at the proper weight ratio. The CS nanoparticles showed higher fluorescence intensity and transfection efficiency than the lipid-based formulation transfection agent by confocal microscopy and flow cytometry analysis. The CS-MB complexes were found to be easily synthesized and exhibited strong enzymatic stability, efficient cellular uptake, high target selectivity and biocompatibility. The CS-MB complexes can also be applied in other cancers just by simply changing for a targeted miRNA highly expressed in those cancer cells. Therefore, it is a promising vehicle used for detecting miRNA expression in living cells.

To explore the risk factors of the occurrence of acute kidney injury (AKI) in critically ill patients, and to investigate the effect of hydroxyethyl starch (HES) on renal function in these patients.A prospective investigation was conducted. Critically ill patients admitted to Department of Critical Care Medicine of Peoples Hospital of Huangshan, Wannan Medical College from March 2012 to October 2013 were enrolled. For all the patients under observation, the following data were collected: demography, comorbidities, clinical presentation, severity of illness, and the use of blood product and drugs. All patients were divided into AKI group and non-AKI group by means of Acute Kidney Injury Network (AKIN) criteria, then the risk factors of AKI were investigated by means of univariate and multivariate logistic regression analysis. The effect of HES 130/0.4 administration on renal function in critically ill patients was evaluated.314 patients were enrolled for study out of 1 152 patients admitted. Among these patients enrolled, 89 of them were found to suffer from AKI. AKI was classified as stage 1 in 59 patients, stage 2 in 19 patients, and stage 3 in 11 patients. It was shown by the univariate analysis that 12 variables were the risk factors of AKI, including age, hypertension, diabetes mellitus, acute physiology and chronic health evaluation II (APACHEII) score, sequential organ failure assessment (SOFA) score, coagulation SOFA score, neurological SOFA score, cardiovascular SOFA score, blood pH on intensive care unit (ICU) admission, blood glucose on ICU admission, accumulating dose of HES, and presence of shock (P < 0.05 or P < 0.01). However, HES administration and daily maximum dose of HES were not the risk factors of AKI in critically ill patients (both P > 0.05). Using the multivariate logistic regression analysis, it was shown that total SOFA score [ odds ratio (OR) = 1.20, 95% confidence interval (95%CI) = 1.09-1.32, P < 0.001 ], hypertension (OR = 2.44, 95%CI = 1.22-4.89, P = 0.012), blood glucose level on ICU admission (OR = 1.85, 95%CI = 1.32-2.59, P < 0.001), and presence of shock (OR = 3.81, 95%CI = 1.93-7.53, P < 0.001) were independent predictors of AKI in critically ill patients, however, the cumulative dose of HES was not independent risk factor for AKI (OR = 0.77, 95%CI = 0.68-0.87, P < 0.001).Total SOFA score, hypertension, blood glucose level on ICU admission, and presence of shock were independent risk factors for AKI in critically ill patients. HES administration may not be a causative factor of an increased risk of AKI in the ICU.
