Abstract
Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e^{+}e^{-}→ωχ_{cJ} (J=0, 1, 2). The process e^{+}e^{-}→ωχ_{c0} is observed for the first time, and the Born cross sections at sqrt[s]=4.23 and 4.26 GeV are measured to be (55.4±6.0±5.9) and (23.7±5.3±3.5) pb, respectively, where the first uncertainties are statistical and the second are systematic. The ωχ_{c0} signals at the other seven energies and the e^{+}e^{-}→ωχ_{c1} and ωχ_{c2} signals are not significant, and the upper limits on the cross sections are determined. By examining the ωχ_{c0} cross section as a function of center of mass energy, we find that it is inconsistent with the line shape of the Y(4260) observed in e^{+}e^{-}→π^{+}π^{-}J/ψ. Assuming the ωχ_{c0} signals come from a single resonance, we extract the mass and width of the resonance to be (4230±8±6) MeV/c^{2} and (38±12±2) MeV, respectively, and the statistical significance is more than 9σ.

Abstract
Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of sqrt[s]=4.23, 4.26, and 4.36 GeV, we observe e(+)e(-)→π(0)π(0)hc for the first time. The Born cross sections are measured and found to be about half of those of e(+)e(-)→π(+)π(-)hc within less than 2σ. In the π(0)hc mass spectrum, a structure at 4.02 GeV/c(2) is found. It is most likely to be the neutral isospin partner of the Zc(4020)(±) observed in the process of e(+)e(-)→π(+)π(-)hc being found. A fit to the π(0)hc invariant mass spectrum, with the width of the Zc(4020)(0) fixed to that of its charged isospin partner and possible interferences with non-Zc(4020)(0) amplitudes neglected, gives a mass of (4023.9±2.2±3.8) MeV/c(2) for the Zc(4020)(0), where the first error is statistical and the second systematic.

Abstract
We report on the magnetotransport properties of chemical vapor deposition grown films of interconnected Bi2Te3 nanoplates. Similar to many other topological insulator (TI) materials, these granular Bi2Te3 films exhibit a linear magnetoresistance (LMR) effect which has received much recent attention. Studying samples with different degree of granularity, we find a universal correlation between the magnitude of the LMR and the average mobility (⟨μ⟩) of the films over nearly 2 orders of magnitude change of ⟨μ⟩. The granularity controlled LMR effect here is attributed to the mobility fluctuation induced classical LMR according to the Parish-Littlewood theory. These findings have implications to both the fundamental understanding and magnetoresistive device applications of TI and small bandgap semiconductor materials.

Abstract
BACKGROUND/OBJECTIVES Several studies have suggested differential health effects in relation to different meat composition in Western population. The purpose of the study was to examine secular trends in meat and seafood consumption patterns among Chinese adults between 1991 and 2011. SUBJECTS/METHODS Our longitudinal data are from 21,144 adults aged 18-75 in the China Health and Nutrition Survey, prospective cohort study. We assessed the intakes of meat and subtypes with three 24-h dietary recalls. We conducted multilevel mixed-effect logistic and linear regression models to examine meat consumption dynamics. RESULTS The proportions of Chinese adults who consumed red meat, poultry and seafood increased from 65.7% in 1991 to 86.1% in 2011, from 7.5 to 20.9% and from 27.4 to 37.8%, respectively. With rapid decrease in meat intakes since 2009, the intakes of total meat, red meat, poultry and seafood among their consumers were 86.7 g/day, 86.4 g/day, 71.0 g/day and 70.3 g/day in 2011, respectively, which were just slightly higher compared with those in 1991. Fatty fresh pork has been predominantly component of total meat overtime, which consituted 54.0% of total meat intake, 80.0% of fresh red meat intake and 98.7% of fatty fresh red meat intake in 2011. CONCLUSION Over the past two decades, meat consumption patterns of Chinese adults have been characterized by having a predominant intake of fatty fresh pork, suboptimal intakes of seafood and increased proportion of adults having excessive intakes of red meat and poultry overtime.

Abstract
The diversity of microbiota in waste waters has not been thoroughly examined, despite the potential impact of microbes on effluent quality. Wastewater microbial communities harbor pathogenic bacteria, viruses, and parasites. To study microbial communities in domestic sewage outfalls, 454 pyrosequencing technology was used to investigate the composition of microbial communities associated with municipal wastewater during different seasons sampled over the course of one year. A total of 195,103 16S rRNA gene sequences were obtained from 20 samples. The R software was used to calculate the number of indices describing the alpha diversity associated with each bacterial assemblage. In this study, the a-diversity index (H', D, J), in which higher numbers represent more diversity, was found to change with seasonal cycle. The diversity of bacterial assemblages was high in all samples, indicating that species diversity was also very high. The taxonomic composition of the assemblages varied considerably among samples, with some dominated by Proteobacteria, while others were dominated by Bacteroidetes or Firmicutes. In 2 samples, the relative prevalence of Proteobacteria exceeded 90%. α-Proteobacteria, b-proteobacteria, and g-proteobacteria represented 90% or more of all Proteobacteria. The present characterization of wastewater from five sewage outfalls indicated the presence of some pathogenic bacteria. The g-Proteobacteria in sewage wastefalls identified in this study included Enterobacteriaceae, Vibrionaceae, Pseudomonadaceae, Salmonella, Yersinia, Vibrio, and Pseudomonas aeruginosa.

Abstract
Using a sample of 1.3 × 10(9) J/ψ events collected with the BESIII detector, we report the first observation of η(')→π(+)π(-)π(+)π(-) and η(')→π(+)π(-)π(0)π(0). The measured branching fractions are B(η(')→π(+)π(-)π(+)π(-)) = [8.53 ± 0.69(stat.) ± 0.64(syst.)]×10(-5) and B(η(')→π(+)π(-)π(0) π(0)) = [1.82 ± 0.35(stat.) ± 0.18(syst.)] × 10(-4), which are consistent with theoretical predictions based on a combination of chiral perturbation theory and vector-meson dominance.

Abstract
Development and selection of an ideal scaffold is of importance for tissue engineering. Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) is a biocompatible bioresorbable copolymer that belongs to the polyhydroxyalkanoate family. Because of its good biocompatibility, PHBHHx has been widely used as a cell scaffold for tissue engineering. This review focuses on the utilization of PHBHHx-based scaffolds in tissue engineering. Advances in the preparation, modification, and application of PHBHHx scaffolds are discussed.

Abstract
We study the superconducting vortex states induced by the interplay of long-range Pearl repulsion and short-range intervortex attraction using Langevin dynamics simulations. We show that at low temperatures the vortices form an ordered Abrikosov lattice both in low and high fields. The vortices show distinctive modulated structures at intermediate fields depending on the effective intervortex attraction: ordered vortex chain and kagome-like vortex structures for weak attraction; bubble, stripe and antibubble lattices for strong attraction. Moreover, in the regime of the chain state, the vortices display structural transitions from chain to labyrinthine (or disordered chain) and/or to disordered states depending on the strength of the disorder.

Abstract
SRY-related high-mobility-group box 9 (Sox9) gene is a cartilage-specific
transcription factor that plays essential roles in chondrocyte differentiation and
cartilage formation. The aim of this study was to investigate the feasibility of
genetic delivery of Sox9 to enhance chondrogenic differentiation of human umbilical
cord blood-derived mesenchymal stem cells (hUC-MSCs). After they were isolated from
human umbilical cord blood within 24 h after delivery of neonates, hUC-MSCs were
untreated or transfected with a human Sox9-expressing plasmid or an empty vector. The
cells were assessed for morphology and chondrogenic differentiation. The isolated
cells with a fibroblast-like morphology in monolayer culture were positive for the
MSC markers CD44, CD105, CD73, and CD90, but negative for the differentiation markers
CD34, CD45, CD19, CD14, or major histocompatibility complex class II. Sox9
overexpression induced accumulation of sulfated proteoglycans, without altering the
cellular morphology. Immunocytochemistry demonstrated that genetic delivery of Sox9
markedly enhanced the expression of aggrecan and type II collagen in hUC-MSCs
compared with empty vector-transfected counterparts. Reverse transcription-polymerase
chain reaction analysis further confirmed the elevation of aggrecan and type II
collagen at the mRNA level in Sox9-transfected cells. Taken together, short-term Sox9
overexpression facilitates chondrogenesis of hUC-MSCs and may thus have potential
implications in cartilage tissue engineering.

[PMID: 24619105 DOI: 10.1038/ejcn.2014.24] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2014] [Revised: 01/22/2014] [Accepted: 01/24/2014] [Indexed: 11/09/2022]
Abstract
BACKGROUND/OBJECTIVES To analyze the time trends in total dietary fiber (DF) intake, DF food sources and total DF intake per 1000 kcal (DF density) in Chinese adults aged 45 years and above in the past 20 years. SUBJECTS/METHODS We used the data from the China Health and Nutrition Survey (CHNS) collected in 1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011. Adults who were aged 45 years and above were included in each round. Water-insoluble DF intake was calculated by substituting the water-insoluble DF content of each food in the Chinese Food Composition Table (FCT) for food intake. Total DF was calculated according to the convert index, which indicates the ratio between total DF and water-insoluble DF for each food group. RESULTS The mean daily total DF intake in males was 19.5 g/day in 1991 and 19.4 g/day in 2011. In females, it was 17.5 g/day in 1991 and 17.6 g/day in 2011. DF density increased in both males and females from 2004 to 2011. It was 9.0 g/1000 kcal in males and 9.5 g/1000 kcal in females in 2011. The major food sources of water-insoluble DF were cereals and vegetables. Communities with different levels of urbanization showed different trends in total DF intake: decreased consumption (2.9 g) in residents of low-urbanization communities and increased consumption (3.1 g) in those of high-urbanization communities. CONCLUSION The average total DF intake in Chinese adults aged 45 years and above remained at a stable level. DF density increased because of slight decrease in energy intake. More public health messages should be disseminated, especially to the residents of low-urbanization communities, so as to increase their daily DF intake to a level close to the recommended DF intake.

Abstract
With data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies from 4.009 to 4.420 GeV, the process e+e-→ γX(3872) is observed for the first time with a statistical significance of 6.3σ. The measured mass of the X(3872) is (3871.9 ± 0.7s tat ± 0.2 syst) MeV/c(2), in agreement with previous measurements. Measurements of the product of the cross section σ[e+e- → γX(3872)] and the branching fraction B[X(3872)→π+π-J/ψ] at center-of-mass energies 4.009, 4.229, 4.260, and 4.360 GeV are reported. Our measurements are consistent with expectations for the radiative transition process Y(4260) → γX(3872).

Abstract
We report on a study of the process e+ e- → π± (DD*)∓ at sqrt[s] = 4.26 GeV using a 525 pb(-1) data sample collected with the BESIII detector at the BEPCII storage ring. A distinct charged structure is observed in the (DD*)∓ invariant mass distribution. When fitted to a mass-dependent-width Breit-Wigner line shape, the pole mass and width are determined to be Mpole = (3883.9±1.5(stat)±4.2(syst)) MeV/c2 and Γpole = (24.8±3.3(stat)±11.0(syst)) MeV. The mass and width of the structure, which we refer to as Zc(3885), are 2σ and 1σ, respectively, below those of the Zc(3900) → π± J/ψ peak observed by BESIII and Belle in π+ π- J/ψ final states produced at the same center-of-mass energy. The angular distribution of the πZc(3885) system favors a JP = 1+ quantum number assignment for the structure and disfavors 1- or 0-. The Born cross section times the DD* branching fraction of the Zc(3885) is measured to be σ(e+ e- → π± Zc(3885)∓)×B(Zc(3885)∓ → (DD*)∓) = (83.5±6.6(stat)±22.0(syst)) pb. Assuming the Zc(3885) → DD* signal reported here and the Zc(3900) → πJ/ψ signal are from the same source, the partial width ratio (Γ(Zc(3885) → DD*)/Γ(Zc(3900) → πJ/ψ)) = 6.2±1.1(stat)±2.7(syst) is determined.

Abstract
China's food consumption patterns and eating and cooking behaviours changed dramatically between 1991 and 2011. Macronutrient composition has shifted towards fats, and protein and sodium intakes remain high and potassium intake low. The rapid decline in intake of coarse grains and, later, of refined grains and increases in intake of edible oils and animal-source foods accompanied by major eating and cooking behaviour shifts are leading to what might be characterized as an unhealthy Western type of diet, often based on traditional recipes with major additions and changes. The most popular animal-source food is pork, and consumption of poultry and eggs is increasing. The changes in cooking and eating styles include a decrease in the proportion of food steamed, baked, or boiled, and an increase in snacking and eating away from home. Prior to the last decade, there was essentially no snacking in China except for hot water or green tea. Most recently, the intake of foods high in added sugar has increased. The dietary shifts are affected greatly by the country's urbanization. The future, as exemplified by the diet of the three mega cities, promises major growth in consumption of processed foods and beverages.

Abstract
We study e+e-→π+π-hc at center-of-mass energies from 3.90 to 4.42 GeV by using data samples collected with the BESIII detector operating at the Beijing Electron Positron Collider. The Born cross sections are measured at 13 energies and are found to be of the same order of magnitude as those of e+e-→π+π-J/ψ but with a different line shape. In the π±hc mass spectrum, a distinct structure, referred to as Zc(4020), is observed at 4.02 GeV/c2. The Zc(4020) carries an electric charge and couples to charmonium. A fit to the π±hc invariant mass spectrum, neglecting possible interferences, results in a mass of (4022.9±0.8±2.7) MeV/c2 and a width of (7.9±2.7±2.6) MeV for the Zc(4020), where the first errors are statistical and the second systematic. The difference between the parameters of this structure and the Zc(4025) observed in the D*D[over ¯]* final state is within 1.5σ, but whether they are the same state needs further investigation. No significant Zc(3900) signal is observed, and upper limits on the Zc(3900) production cross sections in π±hc at center-of-mass energies of 4.23 and 4.26 GeV are set.

Abstract
The immune deficiency (IMD) signal pathway mediates immunity against Gram-negative bacteria in Drosophila. Recent studies show that the IMD pathway also involves in antiviral innate immune responses. The functions of the pathway in crustacean immunity are largely unknown. In this paper, two IMDs (FcIMD and PcIMD), one of the key elements of the IMD pathway, were identified from Chinese white shrimp Fenneropenaeus chinensis and red swamp crayfish Procambarus clarkii. Both proteins have a death domain located at the C-terminal. FcIMD was mainly expressed in the gills and stomach and PcIMD was mainly detected in the heart, hepatopancreas, and stomach. FcIMD peaked in hemocytes at 12 h after white spot syndrome virus (WSSV) challenge and it peaked in the gills at 6 h after WSSV challenge, but it was decreased at 2 h and kept the low level to 24 h in hemocytes and no obviously change in gill after Vibrio anguillarum challenge. PcIMD first decreased in hemocytes at 2 h and peaked at 12 h in hemocytes after V. anguillarum challenge. It was also upregulated in gill after bacterial challenge, peaked at 2 h, and decreased at 6 h, and then gradually increased at 12-24 h. PcIMD has no significant change in hemocytes and gill after WSSV challenge. Western blot analysis detected FcIMD protein in all tissues, and immunocytochemical analysis localized FcIMD in the cytoplasm of hemocytes. RNA interference analysis showed that the IMD pathway was involved in regulating the expression of three kinds AMP genes, including crustins, anti-lipopolysaccharide factors and lysozymes, in shrimp and crayfish. They are Cru 1, Cru 2, ALF 1, ALF 2 and Lys 1 in crayfish, and Cru1, Cru 3, ALF 6, ALF 8, and Lys2 in shrimp. These results suggest that although IMD distribution and expression patterns have some differences, the IMD pathway may have conserved function for AMP regulation in shrimp and crayfish immunity against Gram-negative bacteria.

Abstract
The aim of this study was to investigate the potential correlation between polymorphisms of the estrogen receptor (ER)-β gene (RsaI and AluI) and ethnic Han Chinese human idiopathic thin endometrium. A total of 120 patients with idiopathic thin endometrium and 120 sterility patients with normal endometrium thickness (controls) were included in the study. RsaI and AluI polymorphisms of the ER-β gene were analyzed with polymerase chain reaction-restriction fragment length polymorphism. The distribution of polymorphisms, genotype, allele, and haplotype was compared between the 2 groups. A significant difference in the RsaI genotype was observed between idiopathic thin endometrium patients and controls. The distribution of the R allele of the RsaI polymorphism in idiopathic thin endometrium patients was 37.1% compared with 48.3% in controls. The odds ratio was 0.630 (95% confidence interval = 0.438 to 0.907, P = 0.013). No significant difference in the genotype of the AluI polymorphism was found between the two groups. The linkage disequilibrium between RsaI and AluI haploids was not significant in either group, with D' values of 0.2036 and 0.0685 in the idiopathic thin endometrium patients and controls, respectively. The results of this study suggest a potential role of the ER-β gene polymorphisms in the etiology of idiopathic atrophic endometrium and the R allele as a potential protective factor in ethnic Han Chinese.

Abstract
Angiopoietin (Ang)-1 and Ang-2 interact in angiogenesis to activate the Tie-2 receptor, which may be involved in new vessel maturation and regression. Mast cells (MCs) are also involved in formation of new blood vessels and angiogenesis. The present study was designed to test whether MCs can mediate angiogenesis in myocardial microvascular endothelial cells (MMVECs). Using a rat MMVEC and MC co-culture system, we observed that Ang-1 protein levels were very low even though its mRNA levels were increased by MCs. Interestingly, MCs were able to enhance migration, proliferation, and capillary-like tube formation, which were associated with suppressed Ang-2 protein expression, but not Tie-2 expression levels. These MCs induced effects that could be reversed by either tryptase inhibitor [N-tosyl-L-lysine chloromethyl ketone (TLCK)] or chymase inhibitor (N-tosyl-L-phenylalanyl chloromethyl ketone), with TLCK showing greater effects. In conclusion, our data indicated that MCs can interrupt neovessel maturation via suppression of the Ang-2/Tie-2 signaling pathway.

Abstract
In typical laser-driven proton acceleration experiments Thomson parabola proton spectrometers are used to measure the proton spectra with very small acceptance angle in specific directions. Stacks composed of CR-39 nuclear track detectors, imaging plates, or radiochromic films are used to measure the angular distributions of the proton beams, respectively. In this paper, a new proton spectrometer, which can measure the spectra and angular distributions simultaneously, has been designed. Proton acceleration experiments performed on the Xtreme light III laser system demonstrates that the spectrometer can give angle-resolved spectra with a large acceptance angle. This will be conductive to revealing the acceleration mechanisms, optimization, and applications of laser-driven proton beams.

Fast-track surgery improves postoperative recovery in patients undergoing partial hepatectomy for primary liver cancer: A prospective randomized controlled trial. Eur J Surg Oncol 2013; 39:542-7. [PMID: 23562361 DOI: 10.1016/j.ejso.2013.03.013] [Citation(s) in RCA: 81] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2012] [Revised: 03/05/2013] [Accepted: 03/13/2013] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND AND AIM Fast-track surgery (FTS), combining several techniques with evidence-based adjustments, has shown its effectiveness to accelerate recovery, reduce morbidity and shorten hospital stay in many operations. This randomized controlled study was carried out aiming to compare the short-term outcomes of partial hepatectomy for liver cancer managed with FTS or with conventional surgery (CS). METHODS To compare the short-term effects between FTS and CS, a randomized controlled trial was carried out for liver cancer patients undergoing partial hepatectomy from September 2010 to June 2012. RESULTS Patients with liver cancers before receiving partial hepatectomy were randomized into the FTS group (n = 80) and the CS group (n = 80). Compared with the CS group, the FTS group had significantly less complications (P < 0.05), shorter durations of nausea/vomiting, paralytic ileus and hospital stay, higher general comfort questionnaire measures (GCQ) by Kolcaba Line (all P < 0.05), and lower serum levels of C-reactive protein on postoperative days 1, 3, and 5. CONCLUSIONS FTS was safe and efficacious. It lessened postoperative stress reactions and accelerated recovery for patients undergoing partial hepatectomy for liver cancer.

CpG ODN-induced matrix metalloproteinase-13 expression is mediated via activation of the ERK and NF-κB signalling pathways in odontoblast cells. Int Endod J 2013; 46:666-74.

Abstract
AIM To investigate the effects of CpG ODN (CpG oligodeoxynucleotides) to model the action of bacterial challenge on pulpal matrix metalloproteinase-13 (MMP-13) expression and elucidate the associated intracellular signalling pathways. METHODOLOGY Real-time PCR was used to detect the effects of CpG ODN on MMP-13 mRNA expression levels in a murine odontoblast-lineage cell line (OLCs). The possible involvement of TLR9/MyD88, NF-κB or MAPK pathways involved in the CpG ODN-induced MMP-13 expression was examined by real-time PCR, transient transfection, luciferase activity assay and ELISA. Western blotting was performed to assay the phosphorylation of ERK at a range of time points. RESULTS MMP-13 was constitutively expressed in OLCs, and their exposure to CpG ODN significantly increased MMP-13 expression. Pre-treatment of OLCs with the inhibitory peptide MyD88, or chloroquine, attenuated the CpG ODN-induced expression of MMP-13. Treatment of the OLCs with CpG ODN increased NF-κB-luciferase activity. This activity was decreased by the over-expression of a nondegrading mutant of IκBα (IκBαSR), although enhanced by the over-expression of NF-κB p65. MMP-13 expression induced by CpG ODN was markedly suppressed by NF-κB inhibitors (pyrrolidine dithiocarbamate, PDTC), IκBα phosphorylation inhibitors (Bay 117082) or IκB protease inhibitor (L-1-tosylamido-2-phenylethyl chloromethyl ketone, TPCK). The inhibitor of ERK1/2, U0126, but not inhibitors of p38 MAPK and JNK, SB203580 and SP600125, decreased CpG ODN-mediated MMP-13 expression. CONCLUSION The CpG ODN-induced MMP-13 expression in OLCs is mediated through TLR9, NF-κB and the ERK pathway indicating that potentially the recognition of CpG ODN by TLR9 on odontoblasts may regulate the remodelling of injured dental pulp and hard tissues by inducing MMP-13 expression.

Abstract
The time-delay effect on the bursting of the synchronized state of coupled Hindmarsh-Rose neurons is investigated in this paper. The time-delay influence on the structure of the slow manifold is first studied by using the method of stability switch. And then on the basis of the geometric singular perturbation theory, case studies are given to show that the time delay can suppress the bursting oscillation or lead to more complex dynamics. In particular, the mechanism of the transition from bursting oscillation to relaxation oscillation and to chaotic bursting is stated. Numerical results are given to demonstrate the validity of the analytical results.

Abstract
This is the first report on the determination of proteins with tetra-substituted sulphonated aluminum phthalocyanine (AlS(4)Pc) by resonance light-scattering (RLS). At pH 3.0, the weak RLS of AlS(4)Pc can be enhanced by the addition of proteins. Based on this, a novel quantitative method has been developed for the determination of proteins in aqueous solutions. Under optimal conditions, the linear ranges of the calibration curves were 0.050-2.0 mug ml(-1) for both human serum albumin (HSA) and human r-IgG. The detection limits were 12.7 ng ml(-1) for HSA and 16.1 ng ml(-1) for human r-IgG. The method has been applied to the analysis of total protein in human serum samples collected from the hospital and the results were in good agreement with those reported by the hospital, which indicates that the method presented here is not only sensitive, simple, but also reliable and suitable for practical applications.

Abstract
PURPOSE Conditional survival (CS) offers more relevant prognostic information for patients once they have survived for some time. The objective of this study was to determine the CS for advanced renal cell carcinoma (RCC) patients treated with vascular endothelial growth factor-targeted therapy. METHODS A total of 345 patients treated between 2006 and 2011 fulfilled the inclusion criteria and were reviewed for analyses. The 1-year conditional and actual survival rates were calculated for survivors from treatment to month 24. Subgroup-specific CS rates were generated after adjustment of the covariate influence. The Cox proportional hazard models were used to assess the prognostic factors at baseline and 1-year landmark. RESULTS The probabilities of surviving an additional year given survival to 6, 12, 18, and 24 months were 72.2, 76.3, 78.2, and 78.6 %, respectively. Remarkable increase in CS was observed in patients initially classified as intermediate or poor risk according to Heng risk groups. For patients survived 24 months after treatment, the adjusted CS for the following year was over 80 % regardless of initial risk attribution. Compared to baseline analysis, Heng risk groups were less predictive of survivorship after surviving 1 year. The addition of disease control status to multifactorial model significantly improved survival estimation for 1-year survivors (p < 0.01). CONCLUSIONS CS provides useful information regarding life expectancy for survivors of advanced RCC treated with targeted therapy. Furthermore, disease control status within a specific period of time is critical to the prediction of subsequent survival.

Abstract
We aimed to determine whether acute treatment with candesartan cilexetil (CV-11974), an angiotensin II type 1 receptor blocker (ARB) can improve insulin sensitivity in high-fructose-diet (HFD)-fed rats. In vivo glucose utilization was measured by applying the euglycemic clamp technique and the expression levels of insulin-signaling molecules in skeletal muscles were examined by western blotting. A bolus injection of CV-11974 improved the glucose infusion rate (GIR) of HFD-fed rats to the level of the control rats. Furthermore, restoration of impaired tyrosine phosphorylation of insulin receptor (IR) β, Akt phosphorylation at Ser⁴⁷³ and Thr³⁰⁸, and phosphorylation of the 160-kDa Akt substrate (AS160) in the skeletal muscles of HFD-fed rats were achieved by this treatment. These results suggest that acute administration of candesartan cilexetil can increase insulin sensitivity of HFD-fed rats, which is associated with improved insulin signaling in skeletal muscles.
