Abstract
Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common respiratory disease which has become an important public health problem. A high prevalence of OSAHS in the elderly may suggest that aging could be considered as a risk factor for the development of OSAHS. Recent work that has advanced understanding of mutations accumulating over time in the mitochondrial DNA (mtDNA) has been closely associated with aging. More and more researchers pay attention to changes of mitochondria morphology, electron transport chain enzymes and mtDNA. The process research of accumulation of circular mtDNA bearing deletions or mtDNA with accumulated point mutations in OSAHS subjects might be able to make mitochondrial become a representative biomarker for adverse outcomes from oxidative stress and cardiovascular diseases in the future.

Abstract
BACKGROUND Hypertension is common among patients who have undergone liver transplantation and is a major contributor to cardiovascular events. Few studies have studied the risk factors associated with post-liver transplantation (LT) hypertension. This prospective study assessed the prevalence of post-LT hypertension and associated preoperative risk factors. METHODS From May 2008 to December 2009, 79 normotensive adult patients (≥ 18 years old) who underwent living-donor LT with a median follow up of 4.79 ± 0.88 years were enrolled. Patients' pre-LT demographics, clinical data, pre-LT diabetes, and immunosuppressive agents used after LT were studied for their association with post-LT hypertension. RESULTS The prevalence of post-LT hypertension was 49.4%. The independent risk factors for post-living-donor LT hypertension were pre-LT systolic blood pressure (SBP; odds ratio [OR], 1.04; 95% confidence interval [CI], 1.00-1.09; P = .039) and post-LT administration of mammalian target of rapamycin (mTOR) inhibitors (OR, 4.08; 95% CI, 1.40-11.94; P = .010). Pre-LT diabetes had a negative predictive value (OR, 0.15; 95% CI, 0.03-0.74; P = .019). Neither age, male sex, smoking, pre-LT serum cholesterol and triglyceride levels, tacrolimus, nor glucocorticoid was associated with post-LT hypertension. CONCLUSIONS The prevalence of hypertension is high after LT. Higher pre-LT SBP and post-LT mTOR inhibitor administration predispose patients to post-LT hypertension.

Abstract
The value of adding simeprevir (SMV) vs placebo (PBO) to peginterferon and ribavirin (PR) for treatment of chronic hepatitis C virus infection was examined using patient-reported outcomes (PROs); further, concordance of PROs with virology endpoints and adverse events (AEs) was explored. Patients (n = 768 SMV/PR, n = 393 PBO/PR) rated fatigue (FSS), depressive symptoms (CES-D) and functional impairment (WPAI: Hepatitis C Productivity, Daily Activity and Absenteeism) at baseline and throughout treatment in three randomised, double-blind trials comparing the addition of SMV or PBO during initial 12 weeks of PR. PR was administered for 48 weeks (PBO group) and 24/48 weeks (SMV group) using a response-guided therapy (RGT) approach. Mean PRO scores (except Absenteeism) worsened from baseline to Week 4 to the same extent in both groups but reverted after Week 24 for SMV/PR and only after Week 48 for PBO/PR. Accordingly, there was a significantly lower area under the curve (baseline-Week 60, AUC60 ) and fewer weeks with clinically important worsening of scores in the SMV/PR group at any time point. Incidences of patients with fatigue and anaemia AEs were similar in both groups, but FSS scores showed that clinically important increases in fatigue lasted a mean of 6.9 weeks longer with PBO/PR (P < 0.001). PRO score subgroup analysis indicated better outcomes for patients who met the criteria for RGT or achieved sustained virological response 12 weeks post-treatment (SVR12); differences in mean PRO scores associated with fibrosis level were only observed with PBO/PR. Greater efficacy of SMV/PR enabled reduced treatment duration and reduced time with PR-related AEs without adding to AE severity.

Abstract
OBJECTIVES To report the clinical performance of massively parallel sequencing-based non-invasive prenatal testing (NIPT) in detecting trisomies 21, 18 and 13 in over 140,000 clinical samples and to compare its performance in low-risk and high-risk pregnancies. METHODS Between 1 January 2012 and 31 August 2013, 147,314 NIPT requests to screen for fetal trisomies 21, 18 and 13 using low-coverage whole-genome sequencing of plasma cell-free DNA were received. The results were validated by karyotyping or follow-up of clinical outcomes. RESULTS NIPT was performed and results obtained in 146,958 samples, for which outcome data were available in 112,669 (76.7%). Repeat blood sampling was required in 3213 cases and 145 had test failure. Aneuploidy was confirmed in 720/781 cases positive for trisomy 21, 167/218 cases positive for trisomy 18 and 22/67 cases positive for trisomy 13 on NIPT. Nine false negatives were identified, including six cases of trisomy 21 and three of trisomy 18. The overall sensitivity of NIPT was 99.17%, 98.24% and 100% for trisomies 21, 18 and 13, respectively, and specificity was 99.95%, 99.95% and 99.96% for trisomies 21, 18 and 13, respectively. There was no significant difference in test performance between the 72,382 high-risk and 40,287 low-risk subjects (sensitivity, 99.21% vs. 98.97% (P = 0.82); specificity, 99.95% vs. 99.95% (P = 0.98)). The major factors contributing to false-positive and false-negative NIPT results were maternal copy number variant and fetal/placental mosaicism, but fetal fraction had no effect. CONCLUSIONS Using a stringent protocol, the good performance of NIPT shown by early validation studies can be maintained in large clinical samples. This technique can provide equally high sensitivity and specificity in screening for trisomy 21 in a low-risk, as compared to high-risk, population.

Abstract
The functional relevance of the B-cell receptor (BCR) and the evolution of protein kinases as therapeutic targets have recently shifted the paradigm for treatment of B-cell malignancies. Inhibition of p110δ with idelalisib has shown clinical activity in chronic lymphocytic leukemia (CLL). The dynamic interplay of isoforms p110δ and p110γ in leukocytes support the hypothesis that dual blockade may provide a therapeutic benefit. IPI-145, an oral inhibitor of p110δ and p110γ isoforms, sensitizes BCR-stimulated and/or stromal co-cultured primary CLL cells to apoptosis (median 20%, n=57; P<0.0001) including samples with poor prognostic markers, unmutated IgVH (n=28) and prior treatment (n=15; P<0.0001). IPI-145 potently inhibits the CD40L/IL-2/IL-10 induced proliferation of CLL cells with an IC50 in sub-nanomolar range. A corresponding dose-responsive inhibition of pAKT(Ser473) is observed with an IC50 of 0.36 nM. IPI-145 diminishes the BCR-induced chemokines CCL3 and CCL4 secretion to 17% and 37%, respectively. Pre-treatment with 1 μM IPI-145 inhibits the chemotaxis toward CXCL12; reduces pseudoemperipolesis to median 50%, inferring its ability to interfere with homing capabilities of CLL cells. BCR-activated signaling proteins AKT(Ser473), BAD(Ser112), ERK(Thr202/Tyr204) and S6(Ser235/236) are mitigated by IPI-145. Importantly, for clinical development in hematological malignancies, IPI-145 is selective to CLL B cells, sparing normal B- and T-lymphocytes.

Abstract
Ghrelin is known to be a critical stimulator of feeding behavior mainly via actions in the hypothalamus. However, its functional contribution to the control of energy homeostasis under chronic elevated conditions is unknown. Here we show that overproduction of ghrelin via an AAV viral delivery system in the hypothalamus leads to an increase in food intake associated with increases in body weight. However, this increase in food intake is only temporary and is diminished and no longer significant after 3 weeks. Analysis of brain sections of mice 6 weeks after AAV-ghrelin virus injection demonstrates unaltered neuropeptide Y levels but strongly up-regulated pro-opiomelanocortin levels indicating that a compensatory mechanism has been activated to counter regulate the feeding stimulatory actions of ghrelin. This demonstrates that control mechanism exists that is activated under conditions of prolonged high ghrelin levels, which could potentially be utilized to control feeding and the development of obesity.

Abstract
This pooled analysis of five Phase IIb and III studies evaluated the safety and tolerability of simeprevir, a once daily, oral hepatitis C virus (HCV) NS3/4A protease inhibitor. Data were summarised for patients who received simeprevir 150 mg once daily (n = 924) or placebo (n = 540) plus pegylated interferon-α/ribavirin for 12 weeks. During the first 12 weeks of treatment, few patients discontinued simeprevir or placebo due to adverse events (AEs) (both 2.2%). Pruritus (23.8% vs 17.4%), rash (any; 22.9% vs 16.7%) and photosensitivity (3.2% vs 0.6%) [Correction added on 16 January 2015, after first online publication: In the above sentence, the values in 'Photosensitivity' were previously incorrect and have now been changed to 3.2% vs 0.6%.] were more prevalent in the simeprevir vs the placebo groups. Most AEs were grade 1/2 (72.4% for simeprevir vs 71.3% for placebo). All grade 3/4 AEs occurred in <5.0% of patients, except neutropenia (9.8% vs 7.6%). Overall incidence of neutropenia was similar (17.3% vs 15.7%). Incidence of anaemia was 13.2% for simeprevir vs 10.9% for placebo, and incidence of increased bilirubin was 8.4% vs 2.8%. Bilirubin increases were mild-to-moderate and transient without concurrent transaminase increases or association with hepatic injury. Safety and tolerability did not vary with METAVIR score, although increased bilirubin and anaemia were more frequent in simeprevir-treated patients with METAVIR F4 (increased bilirubin, 13.0% vs 3.3%; anaemia, 19.0% vs 14.8%). Serious AEs were infrequent (2.1% for simeprevir vs 3.0% for placebo). No deaths were reported during the first 12 weeks of treatment. Patient-reported fatigue and other outcomes were comparable for both groups, but were of shorter duration for simeprevir due to the use of response-guided therapy. Simeprevir is well tolerated in HCV genotype 1-infected patients.

Abstract
OBJECTIVES Long noncoding RNAs (lncRNAs) have emerged as a novel class of regulatory molecules involved in various biological processes, but their role in osteoarthritis (OA) remains unknown. Therefore, we aimed to reveal lncRNAs expression profile in human osteoarthritic cartilage and explore the potential functions of lncRNAs in OA. METHODS The expression profiles of lncRNAs and mRNAs in OA cartilage were obtained using microarray and verified by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Bioinformatics analyses including lncRNA classification and subgroup analysis, gene ontology (GO) analysis, pathway analysis, network analysis and target prediction were performed. RESULTS There were 3007 upregulated lncRNAs and 1707 downregulated lncRNAs in OA cartilage compared with normal samples (Fold change ≥ 2.0). In addition, 2136 mRNAs were upregulated and 2,241 mRNAs were downregulated in OA cartilage (Fold change ≥ 2.0). The qRT-PCR results of six dysregulated lncRNAs were consistent with the microarray data. 106 lncRNAs and 291 mRNAs composed the coding-non-coding gene co-expression network (CNC network). In the 600 top differentially expressed lncRNAs, 48 lncRNAs were predicted to have more than five cis-regulated target genes and up to 530 lncRNAs might regulate their trans target genes through collaboration with transcriptional factor (TF) SP1. The positive correlation between lncRNA uc.343 and predicted target homeobox gene C8 (HOXC8) expression in SW1353 cells treating with interleukin-1 beta confirmed the target prediction to some extent. CONCLUSIONS This study revealed the expression pattern of lncRNAs in OA cartilage and predicted the potential function and targets, which indicated that lncRNAs may be new biomarkers for diagnosis or novel therapeutic targets of OA.

Abstract
Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies worldwide and occurs at a relatively high frequency in China, yet the mechanisms underlying its devastating outcome remain unclear. Here we report that platelet-activating factor receptor (PAFR), a type of G-protein-coupled receptor, was upregulated in ESCC tumors and cell lines, compared with controls; PAFR levels were positively correlated with ESCC clinical stages and survival time. Overexpression of PAFR promoted the malignant development of ESCC in vitro and in vivo, whereas depletion of PAFR suppressed these effects. Interestingly, PAFR was observed to activate PI3K/AKT (phosphatidylinositol 3-kinase/AKT) through the upregulation of FAK kinase activity. AKT-triggered nuclear factor-κB transcriptionally activated PAFR expression. This mutual positive regulation between PAFR and AKT was required for the aggressiveness of ESCC cells both in vitro and in vivo. Furthermore, treating mice bearing ESCC tumors with cholesterol-conjugated PAFR small interfering RNA effectively inhibited tumor progression and the expression of AKT-mediated oncogenic proteins. Taken together, we made the first demonstration that dysregulation of PAFR and the positive regulatory loop between PAFR and pAKT contribute to malignant progression of ESCC.

Abstract
OBJECTIVE Joint trauma can lead to a spectrum of acute lesions, including cartilage degradation, ligament or meniscus tears, and synovitis, all potentially associated with osteoarthritis (OA). This study was undertaken to generate and validate a murine model of knee joint trauma following noninvasive controlled injurious compression in vivo. METHODS The right knees of 8-week-old mice were placed in a hyperflexed position and subjected to compressive joint loading at 1 of 3 peak forces (3N, 6N, or 9N) for 60 cycles in a single loading period and harvested on days 5, 9, and 14 after loading (n = 3-5 for each time point and for each loading). The left knees were not loaded and were used as the contralateral control. Histologic, immunohistochemical, and enzyme-linked immunosorbent assay analyses were performed to evaluate acute pathologic features in chondrocyte viability, cartilage matrix metabolism, synovial reaction, and serum cartilage oligomeric matrix protein (COMP) levels. RESULTS Acute joint pathology was associated with increased injurious loads. All loading regimens induced chondrocyte apoptosis, cartilage matrix degradation, disruption of cartilage collagen fibril arrangement, and increased levels of serum COMP. We also observed that 6N loading induced mild synovitis by day 5, whereas at 9N, with tearing of the anterior cruciate ligament, severe posttraumatic synovitis and ectopic cartilage formation were observed. CONCLUSION We have established a murine model of knee joint trauma with different degrees of overloading in vivo. Our results suggest that immediate therapies particularly targeted to apoptosis and synovial cell proliferation could affect the acute posttraumatic reaction to potentially limit chronic consequences and OA.

Abstract
The beneficial effect of clothing on a person is important to the criteria for people exposure to radiant heat flux from fires. The thermal protective performance of multilayer thermal protective clothing exposed to low heat fluxes during dry and wet conditions was studied using two designed bench-scale test apparatus. The protective clothing with four fabric layers (outer shell, moisture barrier, thermal linear and inner layer) was exposed to six levels of thermal radiation (1, 2, 3, 5, 7 and 10kW/m(2)). Two kinds of the moisture barrier (PTFE and GoreTex) with different vapor permeability were compared. The outside and inside surface temperatures of each fabric layer were measured. The fitting analysis was used to quantitatively assess the relationship between the temperature of each layer during thermal exposure and the level of external heat flux. It is indicated that there is a linear correlation between the temperature of each layer and the radiant level. Therefore, a predicted equation is developed to calculate the thermal insulation of the multilayer clothing from the external heat flux. It can also provide some useful information on the beneficial effects of clothing for the exposure criteria of radiant heat flux from fire.

Abstract
Rationale Seizures after intracerebral hemorrhage are a common complication and may adversely affect neurological outcome. However, studies are inadequate on the utility of prophylactic anticonvulsant therapy in patients with hemorrhagic stroke, and the results remains controversial. Aims This study aims to determine if short-duration sodium valproate prevents seizure onset or improves the survival and neurological outcome in adults after acute spontaneous supratentorial intracerebral hemorrhage. Design In this randomized, double blinded, placebo-controlled trial, 258 patients meeting the inclusion criteria will be enrolled in the Department of Neurosurgery, West China Hospital. In addition to standard care, patients will be randomly assigned to receive seven-day prophylaxis of sodium valproate 500 mg daily (alternatively 400 mg daily by intravenous infusion in 250 ml 0·9% normal saline) or matching placebo. Patients will be followed up at seven-days, 3, 6, and 12 months. Study outcomes The primary outcomes are early (≤7 days) and late onset seizures (>7 days). Secondary outcomes include midline shift, enlargement of hematoma, death (all cause), adverse effects, and functional outcome assessed by Glasgow Outcome Scale and modified Rankin Scale. Discussion Given the lack of evidence for seizure prophylaxis in patients with acute supratentorial intracerebral hemorrhage, randomized controlled trials are desperately needed. The results from our study are believed to directly influence future prophylactic anticonvulsant therapy of intracerebral hemorrhage.
