Abstract
OBJECTIVE Lung cancer has become the primary cause of cancer-related death now. New therapies targeting the molecular regulatory machinery were required imperatively. MicroRNAs and long noncoding RNAs can respectively or cooperatively function as oncogenes or tumor suppressor genes in human cancers. The present study identified that miR-449a was down-regulated in tissue of human lung cancer. In this study, we aimed to investigate the function of miR-449a in NL9980 and L9981 lung carcinoma cells lines and the relationship with lncRNA nuclear enriched abundant transcript 1 (NEAT1). MATERIALS AND METHODS miR-449a was profiled in several lung carcinoma cell lines by quantitative reverse transcription-polymerase chain reaction RT-PCR. We analyzed the effects of miR-449a overexpression on proliferation, apoptosis and cell cycle in L9981 cells. The regulatory relationship between miR-449a and NEAT1 was predicted in silico and further studied by miR-449a inhibitor and mimics assay. RESULTS miR-449a was expressed in four cell lines, which we selected, however miR-449a was in high level in NL9980 and in low level in L9981 (P < 0.05). When the miR-449a was the overexpression in L9981 cells, the cell growth was suppressed, and the apoptosis cells were promoted compared with the control group (P < 0.05). The G1/G0 became longer and S, G2/M became shorter (P < 0.05) by miR-449a overexpression. Further study of the interaction between miR-449a and NEAT1 show that NEAT1 was up-regulated when cells were transfected with miR-449a inhibitor, and NEAT1 was down-regulated when cells transfected with miR-449a mimics. CONCLUSIONS Our data indicate that miR-449a may function as a suppressor of lung cancer, and affects the expression of NEAT1 in lung cancer cells.

Abstract
OBJECTIVE To investigate the financial burden of patients who had various stages of hepatitis B virus-related diseases and the level of alleviation from financial burden by health insurance schemes in Yunnan province of China. STUDY DESIGN A cross-sectional survey. METHODS Patients' information was consecutively recorded at the First Affiliated Hospital of Kunming Medical University, from December 2012 to June 2013. Consecutive cases of hepatitis B virus (HBV) (520), compensated cirrhosis (91), decompensated cirrhosis (198) and hepatocellular carcinoma (HCC) (131) were recruited from the outpatient and inpatient departments. The total direct costs, hospital charge, outpatient costs, hospitalization fees being reimbursed and household catastrophic health expenditure were estimated for each disease group. RESULTS The average annual direct costs for each disease group were 19,496 RMB for HBV, 28,466 RMB in compensated cirrhosis, 46,061 RMB for decompensated cirrhosis, and 33,044 RMB for HCC patients. Catastrophic health expenditure occurred in all four groups. Health insurance reimbursement released the financial burden incurred by medical expenses of patients under a high level of household economic status. Public health insurance schemes helped the patients to various extents. CONCLUSIONS Among these patient groups, direct costs represent a significant economic burden. Health expenditure and financing systems must be considered to prevent the increase of household catastrophe, particularly among the poor.

Abstract
Viral load reduction facilitates recovery of antiviral T-cell responses. Dynamic alterations in intrahepatic viraemia clearance and immune cell reactivity during the early phase of nucleoside analogue (NA) therapy and the impact of these changes on HBeAg seroconversion are unknown. Fifteen HBeAg-positive chronic hepatitis B (CHB) patients were treated with adefovir dipivoxil. T-cell reactivity to HBV core and surface antigens were tested using ELISPOT assay from baseline to week 48 post-treatment (at 4-week intervals). Before and at week 12 of treatment, paired liver biopsies were analysed for intrahepatic HBV-DNA and cccDNA via real-time fluorescent PCR. In situ detection of CD4(+) , CD8(+) T cells and NK cells was analysed by immunohistochemistry. With viral load reduction, HBV-specific IFN-γ-producing CD4(+) T cells in patients with HBeAg loss were greatly enhanced and reached the highest level at week 12, with further increase observed between week 36 and week 48. After 12 weeks of treatment, total intrahepatic HBV-DNA and cccDNA had significantly decreased; however, there was no difference in the viral loads or extent of reduction between patients with and without HBeAg loss. Paralleling reduction in viral load, intrahepatic CD8(+) T lymphocytes increased in patients with HBeAg loss compared with baseline values. Only one patient without HBeAg loss exhibited similar results. Increased immune cells were observed in certain patients along with reduced hepatic viral loads during the second phase of HBV-DNA decline, which could promote the recovery of antiviral immunity and facilitate HBeAg loss.

Abstract
One of the challenges presented by Candida infections is that many of the isolates encountered in the clinic produce biofilms, which can decrease these pathogens' susceptibilities to standard-of-care antibiotic therapies. Inhibitors of fungal biofilm formation offer a potential solution to counteracting some of the problems associated with Candida infections. A screening campaign utilizing samples from our fungal extract library revealed that a Bionectria ochroleuca isolate cultured on Cheerios breakfast cereal produced metabolites that blocked the in vitro formation of Candida albicans biofilms. A scale-up culture of the fungus was undertaken using mycobags (also known as mushroom bags or spawn bags), which afforded four known [TMC-151s C-F (1-4)] and three new [bionectriols B-D (5-7)] polyketide glycosides. All seven metabolites exhibited potent biofilm inhibition against C. albicans SC5314, as well as exerted synergistic antifungal activities in combination with amphotericin B. In this report, we describe the structure determination of the new metabolites, as well as compare the secondary metabolome profiles of fungi grown in flasks and mycobags. These studies demonstrate that mycobags offer a useful alternative to flask-based cultures for the preparative production of fungal secondary metabolites.

Abstract
BACKGROUND Major adjuvant therapies for biliary tract cancer (BTC) include fluorouracil, gemcitabine and chemoradiation (CRT), but the optimum regimen remains inconclusive. AIM To compare these therapies in terms of patient survival rates after resection and toxic effects. METHODS We searched PubMed for controlled trials comparing the above three therapies with each other or observation alone until 31 January 2014. We estimated the hazard ratios (HRs) for death and odds ratios (ORs) for toxic effects among different therapies. Subgroup analyses based on positive lymph node or resection margin were also performed. RESULTS Twelve eligible articles were included. Gemcitabine improved 5-year survival (HR 2.12, 95% CI, confidence interval 1.23-4.02, P = 0.01), whereas fluorouracil (HR 1.61, 95% CI 0.74-3.67) and CRT (HR 1.55, 95% CI 0.82-3.32) provided a poorer survival outcome compared with gemcitabine after 1 year. Similarly, for 5-year survival rates, although differing, CRT did not provide a significant improvement in survival (HR 0.46, 95% CI 0.20-0.97) compared with gemcitabine. Fluorouracil did not appear to provide benefit over gemcitabine (HR 1.56, 95% CI 0.77-3.35). CRT was ranked highest for toxic effects including haematological (OR 5.45, 95% CI 0.01-483.85) and nonhaematological (OR 5.77, 95% CI 0.01-3807.40). CONCLUSIONS Chemotherapy with gemcitabine is the optimum adjuvant treatment with a balanced benefit-toxicity ratio for resected biliary tract cancer. Chemoradiation was more likely to cause toxic effects.

Abstract
Bromodomain-containing protein 4 (BRD4) is an important epigenetic reader implicated in the pathogenesis of a number of different cancers and other diseases. Brd4-null mouse embryos die shortly after implantation and are compromised in their ability to maintain the inner cell mass, which gives rise to embryonic stem cells (ESCs). Here we report that BRD4 regulates expression of the pluripotency factor Nanog in mouse ESCs and preimplantation embryos, as well as in human ESCs and embryonic cancer stem cells. Inhibition of BRD4 function using a chemical inhibitor, small interfering RNAs, or a dominant-negative approach suppresses Nanog expression, and abolishes the self-renewal ability of ESCs. We also find that BRD4 associates with BRG1 (brahma-related gene 1, aka Smarca4 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a, member 4)), a key regulator of ESC self-renewal and pluripotency, in the Nanog regulatory regions to regulate Nanog expression. Our study identifies Nanog as a novel BRD4 target gene, providing new insights for the biological function of BRD4 in stem cells and mouse embryos. Knowledge gained from these non-cancerous systems will facilitate future investigations of how Brd4 dysfunction leads to cancers.

Abstract
BACKGROUND The processing of proprotein convertase (PC)-mediated neuropeptide plays a very important role in carcinogenesis and tumor proliferation. AIM To investigate proneuropeptide processing mechanism in tumorigenesis and tumor proliferation. MATERIALS AND METHODS The expression and processing profiles of PC1, carboxypeptidase E (CPE), PC2, GHRH, or neuropeptide Y (NPY) gene and protein level were investigated between 42 human breast tumor tissues and 21 tumor-adjacent normal tissues. RESULTS Gene analyses indicated that the proPC1, CPE, or preproNPY gene had higher expression in the breast tumor tissues, whereas the proPC2 or preproGHRH gene showed lower expression in the tissues. Protein analyses showed that the proPC1, PC1, CPE, GHRH, and preproNPY proteins were upregulated in the tumor tissues, whereas the proPC2, PC2, preproGHRH, and NPY proteins were down-regulated in them. The tissue results were highly corroborated with the serum data from the tumor patients and healthy women. CONCLUSIONS The higher PC1 and CPE expressions as well as the transformation of more proGHRH into active GHRH peptide suggest stronger PC1/CPE-mediated neuropeptide processing in the tumor, whereas the lower PC2 expression as well as the transformation of less proNPY into active NPY peptide suggests a weak PC2-mediated processing in it. The alterations of the convertase expressions and processing show that there is a differential proprotein processing system in the tumor, which leads to the abnormal distributions of species, ratio, and concentration of (pro)peptide(s) in the microenvironment of cells. The latter may contribute to cancer progression.
