Abstract
Objective: To study the association between blood pressure related dietary pattern and cognitive impairment in the elderly. Methods: In 2015, all participants who were aged ≥60 and participated in the Nutrition and Chronic disease family cohort were involved in the study. Information on demographic variables, lifestyle and health status was collected. Cognitive performance was assessed by the Mini Mental State Evaluation (MMSE) scale. Blood pressure, height and weight were measured by trained medical personnel and fasting venous blood samples were collected for testing on serum level of triglycerides and total cholesterol. Both SBP and DBP were used as response variables when dietary patterns were identified by reduced rank regression method. Logistic regression models were fit to explore the associations of scores on blood pressure-related dietary pattern and cognitive impairment. Results: Two blood related dietary patterns were identified. The first one was characterized by high consumption of vegetables and less meat, eggs and dessert (Pattern 1), while the second one was with high consumption of meat, soy products, wine and fried foods and less intake of dairy (Pattern 2). Data showed that the Pattern 1 was associated with the risk of cognitive impairment. Comparing with the lowest quartile of score of this dietary pattern, the risk of cognitive impairment in the highest quartile group showed a significant (P<0.01) increase, with OR=1.94 (1.21-3.11) and showing significant (P=0.002) linear trend. However, no significant association was observed (P>0.05) with cognitive impairment in the second dietary pattern. Conclusion: Blood pressure-related dietary pattern was positively associated with cognitive impairment.

Abstract
OBJECTIVE To investigate both the relationship and underlying mechanism between miR-30a and migraine. PATIENTS AND METHODS Peripheral blood samples were collected from migraine patients and healthy people to extract RNA for quantitative Real-time PCR (qRT-PCR). The relationship between mRNA expressions and patient data was analyzed by t-test. Target genes of miR-30a were predicted by the TargetScan. The binding of miR-30a to the target gene was verified by dual fluorescein reporter assay. The protein expression of calcitonin/alpha-CGRP gene (CALCA), the miR-30a target gene, was detected by Western blot. RESULTS Expression levels of miR-30a in peripheral blood of migraine patients were significantly lower than those of healthy controls detected by qRT-PCR, and the methylation level of miR-30a in promoter region was remarkably increased. In addition, expression levels of miR-30a were significantly decreased in patients with bilateral seizures, persistent pain and high pain index. CALCA was found to be the target gene of miR-30a via bioinformatics analysis. We verified that miR-30a degrades CALCA by dual-luciferase reporter assay. Western blot results showed that overexpression of miR-30a down-regulated the CALCA expression, and knockdown of miR-30a upregulated the CALCA expression. CONCLUSIONS Expression levels of miR-30a are significantly decreased in migraine patients and can relieve migraine through the degradation of CALCA.

Abstract
Since the invention of sugar, added sugars bring us enjoyment. As consumption continues to rise, especially the advent of sugary drinks makes it easier for people to consume added sugars, less sugars and reduced sugars have also become a of concern around the world. In recent years, in WHO and several countries, tax on sugary beverages has been designed to reduce the intake of sugar and prevent the economic costs of obesity and other diseases. This paper reviews the WHO's proposal on sugary drinks tax and the progress of sugary drinks tax in Hungary, Finland, France, Mexico, the United States, South Africa and other countries and regions. The effect of policy on sugary drinks tax was analyzed and considered. Suggestion and support for the progress of China's reduced sugars was provided in the last.

Abstract
Objective: To investigate the epidemiological characteristics of waist circumference (WC) and abdominal obesity (AO) among Chinese adults aged 18 and above. Methods: Data were collected from China National Nutrition and Health Surveillance in 2010-2012. Multi-stage stratifies proportion to the population cluster random sampling method was conducted to determine 120 265 subjects aged 18 and above at 150 counties in 31 provinces in China mainland. WC was determined for all subjects, and AO was judged according to the "Healthy Adult Weight Determination" (WS/T 428-2013). Using the demographic data published by the National Bureau of Statistics of China in 2009, we performed complex sampling weighted treatment to calculate the WC, AO rate and 95%CI. Results: The mean WC of Chinese men aged 18 and above was 82.8 cm, which of urban men (84.1 cm) was higher than that of rural men (81.4 cm) (P<0.001). The average WC of women was 78.5 cm. There was no statistical difference between urban (78.7 cm) and rural women (78.4 cm) (P=0.965). With the increase of education level, the mean WC of male increased gradually from 81.2 cm to 84.3 cm (P<0.001), and the mean WC of female decreased from 80.3 cm to 74.3 cm (P<0.001). With the family income rose, the mean WC of men increased gradually from 81.9 cm to 84.7 cm (P<0.001), and the mean of WC of women decreased from 78.8 cm to 77.6 cm (P<0.001). The AO rate was 25.7% (95% CI: 23.7%-27.7%) in adults aged 18 years and older. The AO rate in urban males (29.8% (95%CI: 26.5%-33.1%)) was significantly higher than that of rural males (22.3% (95%CI: 19.3%-25.2%)) (P=0.001). There was no significant difference in the female AO rate between urban (25.6% (95%CI: 22.8%-28.4%)) and rural areas (25.1% (95%CI: 22.2%-27.9%)) (P=0.772). With the increase of the educational level, the AO rate of men increased from 20.1% (95%CI: 18.0%-22.1%) to 32.6% (95%CI: 28.6%-36.6%) (P<0.001), the rate of women decreased gradually from 31.3% (95%CI: 28.7%-33.9%) to 13.5% (95%CI: 10.9%-16.1%) (P<0.001). With the increase of family income, the AO rate of male increased gradually from 23.3% (95%CI: 20.7%-25.9%) to 31.8% (95%CI: 27.6%-36.1%) (P<0.001), the rate of female decreased from 26.5% (95% CI: 24.2%-28.7%) to 20.0% (95% CI: 17.2%-22.8%) (P<0.001). Conclusion: The prevalence of AO among Chinese residents aged 18 years and above was high, and there were significant differences in WC and AO rate between men and women under different age, region, educational level and family income level.

Abstract
Tumor cells preferentially adopt aerobic glycolysis for their energy supply, a phenomenon known as the Warburg effect. It remains a matter of debate as to how the Warburg effect is regulated during tumor progression. Here, we show that CHIP (carboxyl terminus of Hsc70-interacting protein), a U-box E3 ligase, suppresses tumor progression in ovarian carcinomas by inhibiting aerobic glycolysis. While CHIP is downregulated in ovarian carcinoma, induced expression of CHIP results in significant inhibition of the tumor growth examined by in vitro and in vivo experiments. Reciprocally, depletion of CHIP leads to promotion of tumor growth. By a SiLAD proteomics analysis, we identified pyruvate kinase isoenzyme M2 (PKM2), a critical regulator of glycolysis in tumors, as a target that CHIP mediated for degradation. Accordingly, we show that CHIP regulates PKM2 protein stability and thereafter the energy metabolic processes. Depletion or knockout of CHIP increased the glycolytic products in both tumor and mouse embryonic fibroblast cells. Simultaneously, we observed that CHIP expression inversely correlated with PKM2 levels in human ovarian carcinomas. This study reveals a mechanism that the Warburg effect is regulated by CHIP through its function as an E3 ligase, which mediates the degradation of PKM2 during tumor progression. Our findings shed new light into understanding of ovarian carcinomas and may provide a new therapeutic strategy for ovarian cancer.

Abstract
A 3.5 nm amorphous CoFeB film was sputtered on GaAs (001) wafer substrate without applying magnetic field during deposition, and a significant in-plane uniaxial magnetic anisotropy (UMA) field (Hu) of about 300 Oe could be achieved. To precisely determine the intrinsic Gilbert damping constant (α) of this film, both ferromagnetic resonance (FMR) and time-resolved magneto-optical Kerr effect (TRMOKE) techniques were utilized. With good fitting of the dynamic spectra of FMR and TRMOKE, α is calculated to be 0.010 and 0.013, respectively. Obviously, the latter is 30% larger than the former, which is due to the transient heating effect during the TRMOKE measurement. In comparison with ordinary amorphous CoFeB films with negligible magnetic anisotropies, α is enhanced significantly in the CoFeB/GaAs(001) film, which may be mainly resulted from the enhanced spin-orbit coupling induced by the CoFeB/GaAs interface. However, the significant in-plane UMA plays minor role in the enhancement of α.

Abstract
Sillago sihama (Forsskål, 1775), a commercially important marine fishery species in the Indo-West Pacific, is being developed as a target species for aquaculture and stock enhancement in China. However, due to the limitations of traditional isolation methods, the available microsatellite loci, or simple sequence repeats (SSRs), of S. sihama lack diversity. We used a stepwise approach including Illumina sequencing, primer screening, and SSR marker validation to develop diverse SSRs for S. sihama. A total of 853.48 Mb clean sequences were assembled with high coverage and sequencing depth, and 27,288 potential SSRs were identified. A set of 18 novel SSR markers with four type motifs including 11 di-, 1 tri-, 5 tetra-, and 1 hexanucleotide repeats were successfully isolated. The ranges of number of alleles per locus and observed and expected heterozygosities were 5-24, 0.226-0.968, and 0.319-0.950, respectively. The diversity parameters exhibited high levels of polymorphism in these 18 loci. Three loci with the presence of both null alleles and inbreeding showed significant deviation from Hardy-Weinberg equilibrium after Bonferroni correction. Moreover, 13 loci developed in S. sihama showed high transferability to the closely related species Sillago japonica. The polymorphic SSR markers developed in this study may serve as valuable tools for further basic and applied research on the genetic resources of S. sihama as well as S. japonica. Our results indicate that this approach, based on next-generation sequencing technology, is convenient, cost-effective, and suitable for SSR marker isolation in other sillaginid fishes.

Abstract
MYB, v-myb avian myeloblastosis viral oncogene homolog, proteins play central roles in plant stress response. Previously, we identified a novel R2R3-MYB transcription factor, GmMYB12B2, which affected the expression levels of some key enzyme genes involved in flavonoid biosynthesis in transgenic Arabidopsis. In the present study, we analyzed the expression levels of GmMYB12B2 under salt, low temperature, drought, abscisic acid (ABA), and ultraviolet (UV) radiation treatments in soybean using semi-quantitative reverse transcription polymerase chain reaction. The expression of GmMYB12B2 was drastically induced by UV irradiation and salt treatment, but no response was detected under low temperature, drought, and ABA stresses. A detailed characterization of the GmMYB12B2 overexpression lines revealed that GmMYB12B2 might be involved in response of plants to UV radiation and salt stresses. Transgenic Arabidopsis lines constitutively expressing GmMYB12B2 showed an increased tolerance to salt and UV radiation treatment compared with wild-type plants. The expression levels of certain salt stress-responsive genes, such as DREB2A and RD17, were found to be elevated in the transgenic plants. These results indicate that GmMYB12B2 acts as a regulator in the plant stress response.

Abstract
The objective of the present study was to summarize the prevalence and influencing factors of metabolically healthy obese (MHO) and metabolically obese but normal weight (MONW) among people ≥ 18 years old in the general population worldwide. We searched for studies of the prevalence of MHO and MONW published in English and Chinese up to October 2013. Pooled prevalence estimates were calculated by a random-effects model according to a Q test. The effects of gender, region, age, sample size, smoking, and alcohol consumption on MHO and MONW were analyzed. Differences between subgroups were assessed by chi-square test. Publication bias was estimated by Egger's test. Studies of MHO and MONW showed heterogeneity (I(2)=99.4% and I(2)=99.7%, respectively). The overall prevalence of MHO and MONW was 7.27% (95% CI 5.92-8.90%) and 19.98% (95% CI 16.54-23.94%), respectively. American populations had the highest MHO prevalence and European populations the highest MONW prevalence. Different patterns of MHO and MONW were observed in the subgroup analysis with respect to gender, age, sample size, smoking, alcohol consumption, and metabolically healthy criteria. The prevalence of both MHO and MONW were affected by gender, region, age, sample size, smoking, alcohol consumption, and metabolically healthy criteria, but studies showed high heterogeneity.

Microsomal omega-6 fatty acid desaturase (FAD2-1B) is an enzyme that regulates the polyunsaturated fatty acid content in soybeans (Glycine max). In this study, the FAD2-1B gene was determined to be highly expressed in soybean seeds using quantitative real-time PCR(qRT-PCR). To investigate the expression pattern and activity of the FAD2-1B promoter, a 1929 bp 5'-upstream genomic DNA fragment, named PF, was isolated according to the soybean genomic sequence. Sequence analysis revealed the presence of many motifs related to seed-specific promoters in the PF fragment, such as E-box, SEF4, Skn-1 motif, AACACA, AATAAA and so on. Tobacco transgenics carrying the gus reporter gene driven by the PF and/or 35S promoters were confirmed by PCR and RT-PCR. qRT-PCR and histochemical GUS assays showed that the PF promoter could regulate gus gene accumulation in seeds and the expression level was higher than in other organs. In the meantime, it exhibited similar activity to the 35S promoter in seeds, which could be associated with seed-related cis-elements found in the 1-248 bp, 451-932 bp, and 1627-1803 bp regions of the promoter.

Abstract
PURPOSE OF INVESTIGATION The clinical manifestations, causes, and methods for the treatment and prevention of ureteral injuries presenting late after gynecological laparoscopic surgeries were investigated. MATERIALS AND METHODS The medical records of patients who experienced delayed recognition of ureteral injuries after gynecological laparoscopic surgeries in the present hospital between 2008 and 2012 were reviewed retrospectively. RESULTS There are three cases of ureteral injuries which are diagnose-delayed, The incidence of the malignant tumor groups was 0.99%, and for malignant patients undergoing laparoscopic lymphadenectomy it was 1.3%. CONCLUSION The main way to prevent delayed ureteral injuries is to avoid adhesion between the ureter and surrounding tissues as well as eliminate electrothermal trauma during laparoscopic operations. Surgical repair is effective for such patients.

Abstract
Activating transcription factor 3 (ATF3) is a stress-induced transcription factor that has been shown to repress inflammatory gene expression in multiple cell types and diseases. However, little is known about the roles and mechanisms of ATF3 in liver ischemia/reperfusion injury (IRI). In warm and cold liver IRI models, we showed that ATF3 deficiency significantly increased ischemia/reperfusion (IR)-stressed liver injury, as evidenced by increased serum alanine aminotransferase levels, histological liver damage, and hepatocellular apoptosis. These may correlate with inhibition of the intrahepatic nuclear factor erythroid-derived 2-related factor 2/heme oxygenase-1 (NRF2/HO-1) signaling pathway leading to enhancing Toll-like receptor 4/nuclear factor kappa beta (TLR4/NF-κB) activation, pro-inflammatory programs and macrophage/neutrophil trafficking, while simultaneously repressing anti-apoptotic molecules in ischemic liver. Interestingly, activation of NRF2/HO-1 signaling using an NRF2 activator, oltipraz (M2), during hepatic IRI-rescued ATF3 anti-inflammatory functions in ATF3-deficient mice. For in vitro studies, ATF3 ablation in lipopolysaccharide (LPS)-stimulated bone marrow-derived macrophages (BMMs) depressed levels of NRF2/HO-1 and PI3K/AKT, resulting in enhanced TLR4/NF-κB activation. Pretreatment of LPS-stimulated BMMs with M2 increased NRF2/HO-1 expression, promoted PI3K/AKT, which in turn suppressed TLR4/NF-κB-mediated proinflammatory mediators. Thus, our results first demonstrate ATF3-mediated NRF2/HO-1 signaling in the regulation of TLR4-driven inflammatory responses in IR-stressed livers. Our findings provide a rationale for a novel therapeutic strategy for managing IR-induced liver injury.

Abstract
BACKGROUND Combined positron-emission tomography and computed tomography (pet-ct) reduces futile thoracotomy (ft) rates in patients with non-small-cell lung cancer (nsclc). We sought to identify preoperative risk factors for ft in patients staged with pet-ct. METHODS We retrospectively reviewed all patients referred to the BC Cancer Agency during 2009-2010 who underwent pet-ct and thoracotomy for nsclc. Patients with clinical N2 disease were excluded. An ft was defined as any of a benign lesion; an exploratory thoracotomy; pathologic N2 or N3, stage iiib or iv, or inoperable T3 or T4 disease; and recurrence or death within 1 year of surgery. RESULTS Of the 108 patients who met the inclusion criteria, ft occurred in 27. The main reason for ft was recurrence within 1 year (14 patients) and pathologic N2 disease (10 patients). On multivariate analysis, an Eastern Cooperative Oncology Group performance status greater than 1, a pet-ct positive N1 status, a primary tumour larger than 3 cm, and a period of more than 16 weeks from pet-ct to surgery were associated with ft. N2 disease that had been negative on pet-ct occurred in 21% of patients with a pet-ct positive N1 status and in 20% of patients with tumours larger than 3 cm and non-biopsy mediastinal staging only. The combination of pet-ct positive N1 status and a primary larger than 3 cm had 85% specificity, and the presence of either risk factor had 100% sensitivity, for ft attributable to N2 disease. CONCLUSIONS To reduce ft attributable to N2 disease, tissue biopsy for mediastinal staging should be considered for patients with pet-ct positive N1 status and with tumours larger than 3 cm even with a pet-ct negative mediastinum.

Abstract
Cadmium sulfide (CdS) and silver sulfide (Ag2S) nanocrystals are deposited on the titanium dioxide (TiO2) nanocrystalline film on indium tin oxide (ITO) substrate to prepare CdS/Ag2S/TiO2/ITO photoelectrodes through a new method known as the molecular precursor decomposition method. The Ag2S is interposed between the TiO2 nanocrystal film and CdS nanocrystals as an energy barrier layer and a light absorber. As a consequence, the energy conversion efficiency of the CdS/Ag2S/TiO2/ITO electrodes is significantly improved. Under AM 1.5 G sunlight irradiation, the maximum efficiency achieved for the CdS(4)/Ag2S/TiO2/ITO electrode is 3.46%, corresponding to an increase of about 150% as compared to the CdS(4)/TiO2/ITO electrode without the Ag2S layer. Our experimental results show that the improved efficiency is mainly due to the formation of Ag2S layer that may increase the light absorbance and reduce the recombination of photogenerated electrons with redox ions from the electrolyte.

Abstract
In this work, the solution-processed CH3NH3PbI3 perovskite/copper indium disulfide (CuInS2) planar heterojunction solar cells with Al2O3 as a scaffold were fabricated at a temperature as low as 250°C for the first time, in which the indium tin oxide (ITO)-coated glass instead of the fluorine-doped tin oxide (FTO)-coated glass was used as the light-incidence electrode and the solution-processed CuInS2 layer was prepared to replace the commonly used TiO2 layer in previously reported perovskite-based solar cells. The influence of the thickness of the as-prepared CuInS2 film on the performance of the ITO/CuInS2(n)/Al2O3/(CH3NH3)PbI3/Ag cells was investigated. The ITO/CuInS2(2)/Al2O3/(CH3NH3)PbI3/Ag cell showed the best performance and achieved power conversion efficiency up to 5.30%.

Abstract
The current-induced motion of magnetic domain walls (DWs) confined to nanostructures is of great interest for fundamental studies as well as for technological applications in spintronic devices. Here, we present magnetic images showing the depinning properties of pulse-current-driven domain walls in well-shaped Permalloy nanowires obtained using photoemission electron microscopy combined with x-ray magnetic circular dichroism. In the vicinity of the threshold current density (Jth = 4.2 × 1011 A.m−2) for the DW motion, discontinuous DW depinning and motion have been observed as a sequence of “Barkhausen jumps”. A one-dimensional analytical model with a piecewise parabolic pinning potential has been introduced to reproduce the DW hopping between two nearest neighbour sites, which reveals the dynamical nature of the current-driven DW motion in the depinning regime.

Abstract
Concurrent chemoradiotherapy is the standard treatment for patients with locally advanced esophageal squamous cell carcinoma. However, a number of patients present intolerance to chemoradiotherapy because of advanced age or malnutrition. Erlotinib, an inhibitor of epidermal growth factor receptor tyrosine kinase, was shown to be effective in treating esophageal carcinoma, with mild toxicities. In this pilot study, we investigated the safety and efficacy of concurrent erlotinib and radiotherapy as an alternative treatment modality for esophageal carcinoma patients who are intolerant to chemoradiotherapy. Pathologically diagnosed esophageal squamous cell carcinoma patients who could not tolerate concurrent chemoradiotherapy were enrolled. All patients were treated with concurrent erlotinib and intensity-modulated radiation therapy. Erlotinib was given orally for 60 days (150 mg per day). Radiotherapy (total dose, 60 Gy) was given at dosages of 2 Gy for a total of 30 times. Immunohistochemical staining was performed to assess epidermal growth factor receptor expression. Toxicities were evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 3.0). The overall survival, progression-free survival, and local-regional relapse-free survival were calculated using the Kaplan-Meier method. Between December 2007 and March 2011, 18 patients were enrolled. The median age was 71.5 years. Primary disease was stages II, III, and IV in 3, 8, and 4 patients, respectively. There were three patients with recurrent disease after radical surgery. The median follow-up time was 17.2 months. Grade 3 esophagitis and skin rash were observed in five (27.8%) and two (11.1%) patients, respectively. Radiation pneumonitis of grades 2 and 5 was observed in one patient each. No grade 3/4 impaired liver function or hematological toxicity was observed. At 1 month after radiotherapy, two (11.1%) patients achieved complete response, 11 (61.1%) patients achieved partial response, and 5 (27.8%) patients had stable disease. The median time of overall survival and progression-free survival was 21.1 and 12 months, respectively. Two-year overall survival, progression-free survival, and local-regional relapse-free survival were 44.4%, 38.9%, and 66.7%, respectively. Five of six patients examined for epidermal growth factor receptor had high expression levels (3+). The relationship between epidermal growth factor receptor expression and treatment outcomes could not be concluded. For esophageal squamous cell carcinoma patients who cannot tolerate chemoradiotherapy, concurrent erlotinib and radiotherapy are tolerable and effective. Valuable markers to predict the effect of erlotinib should be exploited in future studies.

Abstract
In the present study, we compared the therapeutic effect of tumor-selective retroviral replicating vectors (RRV) expressing the yeast cytosine deaminase (CD) delivered by CED or simple injection, followed by systemic administration of the pro-drug, 5-fluorocytosine (5-FC). Treatment with RRV-CD and systemic 5-FC significantly increased survival in rodent U87MG glioma model in comparison to controls (p<0.01). Interestingly, CED of RRV-CD followed by 5-FC further enhanced survival in this animal model in comparison to intra-tumoral injection of RRV-CD followed by systemic 5-FC (p<0.05). High expression levels of Ki-67 were found in untreated tumors compared to treated. Untreated tumors were also much larger than treated. CED resulted in excellent distribution of RRV while only partial distribution of RRV was obtained after injection. Furthermore, RRV-CD and cytosine deaminase were also found in tumors from treated rats at study end-points. These results demonstrated that RRV vectors may efficiently transduce and stably propagate in malignant human glioma, thereby achieving a significant in-situ amplification effect after initial administration. We conclude that delivery of RRV into the glioma by CED provides much wider vector distribution than simple, injection, and this correlated with better therapeutic outcomes.

Abstract
FT-IR spectroscopic and thermodynamic measurements were designed to explore the effect of a macromolecular crowder, dextran, on the temperature and pressure-dependent phase diagram of the protein Ribonuclease A (RNase A), and we compare the experimental data with approximate theoretical predictions based on configuration entropy. Exploring the crowding effect on the pressure-induced unfolding of proteins provides insight in protein stability and folding under cell-like dense conditions, since pressure is a fundamental thermodynamic variable linked to molecular volume. Moreover, these studies are of relevance for understanding protein stability in deep-sea organisms, which have to cope with pressures in the kbar range. We found that not only temperature-induced equilibrium unfolding of RNase A, but also unfolding induced by pressure is markedly prohibited in the crowded dextran solutions, suggesting that crowded environments such as those found intracellularly, will also oppress high-pressure protein unfolding. The FT-IR spectroscopic measurements revealed a marked increase in unfolding pressure of 2 kbar in the presence of 30 wt % dextran. Whereas the structural changes upon thermal unfolding of the protein are not significantly influenced in the presence of the crowding agent, through stabilization by dextran the pressure-unfolded state of the protein retains more ordered secondary structure elements, which seems to be a manifestation of the entropic destabilization of the unfolded state by crowding.
