Apolipoprotein B plays a central role in lipoprotein metabolism. Many studies have evaluated the association between Apolipoprotein B gene polymorphisms (XbaI, EcoRI, SpIns/Del, MspI) and the risk for coronary artery disease and myocardial infarction. However, the results remain inconsistent, particularly among different populations. To more precisely determine the association between Apolipoprotein B gene polymorphisms and coronary artery disease/myocardial infarction risk, we performed a meta-analysis via a comprehensive search of electronic databases (up to February 1st, 2015), odds ratios (OR) and 95 % confidence intervals were calculated using a fixed or random effect model. A total of 47 studies, with 9411 coronary artery disease/myocardial infarction cases and 9082 controls, were included in this meta-analysis. The combined results revealed significant associations between an increased risk of coronary artery disease/myocardial infarction and EcoRI (AA vs GG: OR 1.511, 95 % confidence interval (CI) 1.098, 2.078) and SpIns/Del (DD vs II: OR 1.331, 95 % CI 1.064, 1.665) alleles in the general population. In a subgroup analysis stratified by ethnicity, the T allele of the XbaI variant was associated with a decreased risk in Caucasians, whereas it was associated with an increased risk among the East Asian population. No significant correlation was detected between the A allele of the MspI variant and the coronary artery disease/myocardial infarction risk in either the general population or any ethnic subgroup. The results of our study suggest that Apolipoprotein B gene polymorphisms may affect the coronary artery disease/myocardial infarction susceptibility and these effects may display notable discrepancies among different populations.

The phase separationphenomena or cloud points (CP) behaviorof nonionic octylphenol polyoxyethylene etherwith oxyethylene glycol ether unit of 15 (OP-15) were investigated in aqueous micellar solutions containinghigh concentrations of inorganic salts including NaCl, KCl, MgCl2, CaCl2, BaCl2, AlCl3, FeCl3, Na2SO4and Na2SiO3. The change in CP induced by salts and its mechanism are discussed theoretically. In aqueous solutionscontaining high concentration of salt, for thefirst time the linear relationship between CP and saltconcentrationiswellestablishedtocharacterizethedepressionofCP.Basedonpseudophaseseparationmodel,thermodynamic parameters are estimated and adopted to further describe the phase separation process andthe interactions between OP-15 molecules or the OP-15/water interactions. Thermodynamic parametersincluding standard Gibbs energy change (DG0CP), enthalpy change (DH0CP) and entropy change (DS0CP)indicate that the additions of different salts result in the change in entropy-driven nonspontaneousprocess of phase separation. These data, which are from the compensation temperatures and the changeof molar heat capacity, also prove that different ions induce the change in the interactions betweensurfactant molecules or the surfactant–water interaction and thus affect the depression of CP. Thesefindings help with understanding the effect of inorganic salts, especially the high concentration of salt, onCP of nonionic surfactant and then broadening the application of nonionic surfactant based on CP such asthe extraction of biomaterials in biological samples derived from animals or plants, etc.

Objective: With the background of aging population in China and advances in clinical medicine, the amount of operations on old patients increases correspondingly, which imposes increasing challenges to critical care medicine and geriatrics. The study was designed to describe information on the length of ICU stay from a single institution experience of old critically ill gastric cancer patients after surgery and the framework of incorporating data-mining techniques into the prediction. Methods: A retrospective design was adopted to collect the consecutive data about patients aged 60 or over with a gastric cancer diagnosis after surgery in an adult intensive care unit in a medical university hospital in Shenyang, China, from January 2010 to March 2011. Characteristics of patients and the length their ICU stay were gathered for analysis by univariate and multivariate Cox regression to examine the relationship with potential candidate factors. A regression tree was constructed to predict the length of ICU stay and explore the important indicators. Results: Multivariate Cox analysis found that shock and nutrition support need were statistically significant risk factors for prolonged length of ICU stay. Altogether, eight variables entered the regression model, including age, APACHE II score, SOFA score, shock, respiratory system dysfunction, circulation system dysfunction, diabetes and nutrition support need. The regression tree indicated comorbidity of two or more kinds of shock as the most important factor for prolonged length of ICU stay in the studied sample. Conclusions: Comorbidity of two or more kinds of shock is the most important factor of length of ICU stay in the studied sample. Since there are differences of ICU patient characteristics between wards and hospitals, consideration of the data-mining technique should be given by the intensivists as a length of ICU stay prediction tool.

Background: Chronic myeloid leukemia (CML) is a myeloproliferative disorder of hematopoietic stem cell scarrying the Philadelphia (Ph) chromosome and an oncogenic BCR-ABL1 fusion gene. The tyrosine kinase inhibitor (TKI) of BCR-ABL1 kinase is a treatment of choice for control of CML. Objective: Recent studies have demonstrated that miRNAs within exosomes from cancer cells play crucial roles in initiation and progression. This study was performed to assess miRNAs within exosomes of K562 cells. Methods: miRNA microarray analysis of K562 cells and K562 cell-derived exosomes was conducted with the 6th generation miRCURYTM LNA Array (v.16.0). Gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were also carried out. GO terms and signaling pathways were categorized into 66 classes (including homophilic cell adhesion, negative regulation of apoptotic process, cell adhesion) and 26 signaling pathways (such as Wnt). Results: In exosomes, 49 miRNAs were up regulated as compared to K562 cells, and two of them were further confirmed by quantitative real-time PCR. There are differentially expressed miRNAs between K562 cell derived-exosomes and K562 cells. Conclusion: Selectively expressed miRNAs in exosomes may promote the development of CML via effects on interactions (e.g. adhesion) of CML cells with their microenvironment.

Cervical carcinoma is the main cause of cancer-related mortality in women and is correlated with more than 15 risk cofactors, including infection of cervical cells with high-risk types of HPV (hrHPV). Indeed, both aberrant methylation of the RASSF1A promoter and hrHPV infection are often observed in cervical carcinomas. The purpose of our meta-analysis was to evaluate the role of RASSF1A promoter methylation and hrHPV infection in cervical cancer. Our meta-analysis involved 895 cervical cancer patients and 454 control patients from 15 studies. Our results suggested that RASSF1A promoter hypermethylation increased the risk of cervical cancer (OR=9.77, 95%CI=[3.06, 31.26], P=0.0001, $I^2=78%$). By grouping cases according to cancer subtypes, we found that HPV infection was higher in cervical squamous cell carcinomas (SCCs) than in cervical adenocarcinomas/adenosquamous cancers (ACs/ASCs) (OR=4.00, 95%CI=[1.41, 11.30], P=0.009, $I^2=55%$). Interestingly, HPV infection tended to occur in cervical cancers with relatively low levels of RASSF1A promoter methylation (OR=0.59, 95%CI=[0.36, 0.99], P=0.05, I2=0%). Our study provides evidence of a possible interaction between HPV infection and RASSF1A promoter methylation in the development of cervical cancers.

Purpose Conditional survival (CS) provides important information on survival for a period of time after diagnosis. Currently, information on CS patterns of patients with nasopharyngeal carcinoma (NPC) is lacking. We aimed to analyze survival rate over time and estimate CS for NPC patients using a national population-based registry. Materials and Methods Patients diagnosed with NPC between 1973 and 2007 with at least 5-year follow-up were identified from the Surveillance Epidemiology End Results registry. Traditional survival rates and crude CS estimates were calculated using Kaplan-Meier analysis. Risk-adjusted survival curves were plotted from the proportional hazards model using the correct group prognosis method. Results For 7,713 patients analyzed, adjusted baseline 5-year overall survival improved significantly from 36.0% in patients diagnosed in 1973-1979, 41.7% in 1980-1989, 46.6% in 1990- 1999, to 54.7% in 2000-2007 (p < 0.01). CS analysis demonstrated that for every additional year survived, adjusted probability of surviving the next 5 years increased from 66.7% (localized), 54.0% (regional), and 35.3% (distant) at the time of diagnosis, to 83.7% (localized), 75.0% (regional), and 62.2% (distant) for patients who had survived 5 years. Adjusted 5-year CS differed among age, sex, tumor histology, ethnicity, and stage subgroups initially, but converged with time. Conclusion Treatment outcomes of NPC patients have greatly improved over the decades. Increases in CS become more prominent in patients with distant disease than in those with localized or regional disease as patients survive longer. CS provides more dynamic prognostic information for patients who have survived a period of time after diagnosis.

The extraction and solvent partition of the leaves of Eucalyptus citriodora, and repeated column chromatography for n-BuOH fraction yielded a new flavonoid glycoside, citrioside C (1), along with three known flavonoid glycosides (2-4). The latter were identified with kaempferol-3-O-${\beta}$-$\small{D}$-glucopyranosyl (12)-${\alpha}$-$\small{L}$-rhamnoside (2), kaempferol-3-O-${\alpha}$-$\small{L}$-rhamnoside (3), and quercetin-3-O-${\alpha}$-$\small{L}$-rhamnoside (4). Their chemical structures were identified on the basis of spectroscopic data analyses including NMR, MS, UV, and IR. All constitutents were isolated for the first time from the leaves of Eucalyptus citriodora. The potential antivirus activity of all the isolated compounds was evaluated. Compound 4 showed potent antiviral activity against respiratory syncytial virus with 50% inhibition concentration ($IC_{50}$) value of $1.9{\mu}g/mL$ and selective index value of 9.8.
