4Selection of Parents for Breeding Edible Varieties of Sweetpotato with High Carotene Content显示文摘Sweetpotato varieties with high carotene content have high value for human health. This work aims to improve the breeding efficiency of special varieties with high carotene content by combining molecular markers and agronomic traits to evaluate and screen the parents. The cluster analysis was carried out to identify and screen promising parents by utilizing phenotypic results of the agronomic and characteristic traits, and RAPD and ISSR markers of 15 parents and their offspring by group crossing. Among different parental materials, greater variations were observed in two important traits, the carotene content and the storage root yield. Negative correlation was found between the carotene content and both fresh and dried root yields. The most significant positive correlation was between the carotene content of parents and that of their offspring, with the coefficient of correlation value of 0.7932**. The relationship based on the agronomic characters of the trial materials was not in agreement with the known genealogy, while that based on the molecular marker data showed better result. Each primer amplified 13.8 bands of ISSR markers on average, in which the rate of polymorphic loci was 89.6%. 9.4 bands of RAPD markers were amplified per primer, in which the rate of polymorphic bands was 74.46%. Large genetic variation of carotene content was found among the parents. For analyzing the genetic diversity of sweetpotato, the molecular marker methods were better than morphological traits; ISSR markers were more efficient than RAPD markers. The combination of molecular markers and agronomic trait analysis may provide valuable theoretic basis for selection of parents to breed new varieties with high carotene content.MA Dai-fu LI Qiang LI Xiu-ying LI Hong-min TANG Zhong-hou HU Ling CAO Qing-he XIE Yi-ping WANGXin 2009Agricultural Sciences in China2009,8,10:28

10Berberine Ameliorates High-Fat Diet-Induced Non-Alcoholic Fatty Liver Disease in Rats via Activation of SIRT3/AMPK/ACC Pathway显示文摘This study aimed to verify the effects of berberine(BBR)on the fat metabolism proteins involved in the sirtuin 3(SIRT3)/adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)/acetyl-CoA carboxylase(ACC)pathway in the liver tissues of rats with high-fat diet(HFD)-induced non-alcoholic fatty liver disease(NAFLD).Forty-eight rats were randomly divided into the normal control(NC)group,HFD group or BBR group,with 16 rats in each group.After 8 and 16 weeks of treatment,serum and liver samples were collected.Subsequently,body parameters,biochemical parameters and liver pathology were examined.The expression levels of proteins involved in the SIRT3/AMPK/ACC pathway in the liver were detected by Western blotting.After 8 and 16 weeks of a HFD,the successful establishment of rat models with different degrees of NAFLD was confirmed by hematoxylin and eosin(H&E)and Oil Red O staining.NAFLD rat models exhibited obesity and hyperlipidemia,and the protein expression levels of SIRT3,p-AMPK.p-ACC,and CPT-1A in the liver were significantly decreased compared to those in the NC group.The concurrent administration of BBR with the HFD effectively improved serum and liver lipid profiles and ameliorated liver injury.Furthermore,the protein expression levels of SIRT3,p-AMPK,p-ACC,and CPT-1 A in the liver were significantly increased in the BBR group as compared with those in the HFD group.In conclusion,our data suggest that the mechanism by which BBR ameliorates HFD-induced hepatic steatosis may be related to the activation of the SIRT3/AMPK/ACC pathway in the liver.Yu-pei ZHANG Yuan-jun DENG Kai-rui TANG Run-sen CHEN Shu LIANG Yin-ji LIANG Li HAN Ling JIN Zi-en LIANG Yan-ning CHEN Qin-he YANG 2019Current Medical Science2019,39,1:21
11Effect of cypermethrin insecticide on the microbial community in cucumber phyllosphere显示文摘Cucumber (Cucumis sativus) is one of the most widely used vegetable in the world,and different pesticides have been extensively used for controlling the insects and disease pathogens of this plant.However,little is known about how the pesticides affect the microbial community in cucumber phyllosphere.This study was the first attempt to assess the impact of pyrethroid insecticide cyperemethrin on the microbial communities of cucumber phyllosphere using biochemical and genetic approaches.Phospholipid fatty acid (PLFA) assay indicated that cyperemethrin insecticide treatment led to a significant increase in both total and bacterial biomass and a decrease in fungal biomass and the ratio of Gram-positive (GP) bacteria to Gram-negative (GN) bacteria within the cucumber phyllosphere.Principal-component analyses (PCA) suggested that the number of unsaturated and cyclopropane PLFAs (16:1ω9t,18:1ω7,cy17:0,cy19:0) increased with the insecticide treatment,whereas the saturated PLFA i16:0,i17:0 decreased.The increase of GN bacteria implied that the cypermethrin insecticide might be a nutrient for the growth of these phyllosphere microbes.Terminal restriction fragment length polymorphism (T-RFLP) reinforced the PLFA results.A significant change of bacterial community structure was observed in the separate dendrogram cluster between control and treated samples with the cucumber phyllosphere following cypermethrin insecticide treatment.Moreover,the increased terminal restriction fragments (T-RFs) (58,62,89,99,119,195,239,311,340,and 473 bp) indicated that some bacteria might play a significant role in the insecticide degradation within the cucumber phylosphere,whereas the disappeared T-RFs (44,51,96,223,306,and 338 bp) implied that some other bacteria might potentially serve as microbial indicator of cyperemethrin insecticide exposure.Baoguo ZHANG Zhihui BAI 2008Journal of Environmental Sciences2008,20,11:19

13Daclatasvir plus asunaprevir in treatment-na?ve patients with hepatitis C virus genotype 1b infection显示文摘AIM To assess daclatasvir plus asunaprevir(d UAL) in treatment-na?ve patients from China's Mainland, Russia and South Korea with hepatitis C virus(HCV) genotype 1 b infection. METHODS Patients were randomly assigned(3:1) to receive 24 wk of treatment with d UAL(daclatasvir 60 mg once daily and asunaprevir 100 mg twice daily) beginning on day 1 of the treatment period(immediate treatment arm) or following 12 wk of matching placebo(placebodeferred treatment arm). The primary endpoint was a comparison of sustained virologic response at posttreatment week 12(SVR12) compared with the historical SVR rate for peg-interferon plus ribavirin(70%) among patients in the immediate treatment arm. The first 12 wk of the study were blinded. Safety was assessed in d UAL-treated patients compared with placebo patients during the first 12 wk(doubleblind phase), and during 24 wk of d UAL in both arms combined.RESULTS In total, 207 patients were randomly assigned to immediate(n = 155) or placebo-deferred(n = 52) treatment. Most patients were Asian(86%), female(59%) and aged < 65 years(90%). Among them, 13% had cirrhosis, 32% had IL28 B non-CC genotypes and 53% had baseline HCV RNA levels of ≥ 6 million IU/m L. Among patients in the immediate treatment arm, SVR12 was achieved by 92%(95% confidence interval: 87.2-96.0), which was significantly higher than the historical comparator rate(70%). SVR12 was largely unaffected by cirrhosis(89%), age ≥ 65 years(92%), male sex(90%), baseline HCV RNA ≥ 6 million(89%) or IL28 B non-CC genotypes(96%), although SVR12 was higher among patients without(96%) than among those with(53%) baseline NS5 A resistanceassociated polymorphisms(at L31 or Y93 H). during the double-blind phase, aminotransferase elevations were more common among placebo recipients than among patients receiving d UAL. during 24 wk of d UAL therapy(combined arms), the most common adverse events(≥ 10%) were elevated alanine aminotransferase and upper respiratory tract infection; emergent grade 3-4 laboratory abnormalities were infrequently observed, and all grade 3-4 aminotransferase abnormalities(alanine aminotransferase, n = 9; aspartate transaminase, n = 6) reversed within 8-11 d. Two patients discontinued d UAL treatment; one due to aminotransferase elevations, nausea, and jaundice and the other due to a fatal adverse event unrelated to treatment. There were no treatment-related deaths.CONCLUSION d UAL was well-tolerated during this phase 3 study, and SVR12 with d UAL treatment(92%) exceeded thehistorical SVR rate for peg-interferon plus ribavirin of 70%.Lai Wei Fu-Sheng Wang Ming-Xiang Zhang Ji-Dong Jia Alexey A Yakovlev Wen Xie Eduard Burnevich Jun-Qi Niu Yong Jin Jung Xiang-Jun Jiang Min Xu Xin-Yue Chen Qing Xie Jun Li Jin-Lin Hou Hong Tang Xiao-guang Dou Yash Gandhi Wen-Hua Hu Fiona McPhee Stephanie Noviello Michelle Treitel Ling Mo Jun Deng 2018World Journal of Gastroenterology2018,24,12:17
14NUMERICAL INVESTIGATION OF FLOW PATTERNS IN DIFFERENT PUMP INTAKE SYSTEMS显示文摘A 3-D numerical model for pump intake is established based on the Navier-Stokes equations with the RNG turbulence model and the VOF method to simulate the free surface.The applicability of the proposed model is validated by a test case of non-symmetric pump-intake bay.The predicted locations,structures and shapes of all vortices are in good agreement with those observed in experiments,though with some differences in vorticity strengths.The flow pattern and the efficiency of five types of pump intake systems are studied.The discharge and the velocity uniformity of the intake system are used as indices to evaluate its performance.ZHAN Jie-min WANG Ben-cheng YU Ling-hui LI Yok-sheung TANG Ling 2012Journal of Hydrodynamics2012,24,6:16
15Effects of aspirin on atherosclerosis and the cyclooxygenase-2 expression in atherosclerotic rabbits显示文摘Background Atherosclerosis is a complex vascular inflammatory disease. Aspirin is a mainstay in the prevention of vascular complications of atherosclerosis. In this study, the effectiveness of aspirin in suppressing atherosclerosis and the inflammation process was evaluated in rabbits fed with a high fat diet. Methods Eighteen male New Zealand rabbits were randomly divided into 3 groups: control group, untreated cholesterol-fed group, aspirin treated cholesterol-fed group, which were fed for 12 weeks. After 12 weeks, the aorta was harvested for pathologic morphology observation. Immunohistochemical analysis of cyclooxygenase-2 (COX-2), macrophage and vascular smooth muscle cell (VSMC) was performed. The statistical analysis was performed by the statistical program SPSS10.0. Results The aorta plaque/intima size (P/I) by pathologic morphology observation was 0%, (59.6±13.7)% and (36.3±16.5)% in the control, untreated cholesterol-fed group and aspirin treated group, respectively. The maximum plaque thickness, the degree of artery stenosis and the proportion of the intimal circumference occupied by atheroma of the 3 groups were significantly different from each other (P<0.01). The expression of COX-2 and macrophage in plaque of the aspirin treated group were decreased compared with that in untreated cholesterol-fed group. However, no difference was found in the expression of VSMC between the aspirin treated and the untreated cholesterol-fed group. Conclusion The mechanism of atherosclerosis suppression by aspirin in cholesterol-fed rabbits is related to the inhibition of COX-2 expression together with the reduced inflammation followed by, but not related to the hypolipidemic effects.GUO Yi WANG Qi-zhang TANG Bing-shan ZUO Yan-fang LI Fang-ming JIANG Xin WANG Ling MA Ke-fu 2006Chinese Medical Journal2006,,21:16

17Liver Enzymes Concentrations Are Closely Related to Pre-diabetes:Findings of the Shanghai Diabetes Study Ⅱ (SHDS Ⅱ)显示文摘Objective To investigate the relationship of liver enzymes with hyperglycemia in a large population in Shanghai and identify the association between liver enzymes and insulin resistance.Methods A total of 3 756 participants were enrolled.Each participant underwent an oral glucose tolerance test and completed a questionnaire.Anthropometric indices were recorded and serum samples were collected for measurement.Results Liver enzymes concentrations were independently associated with i-IGT,IFG+IGT,and diabetes.With the increase of ALT and GGT concentrations,ORs for i-IGT,IFG+IGT,and diabetes increased gradually.By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile (Q1),ORs for i-IGT,IFG+IGT,or diabetes was significant after adjustment.Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR (95% CI):2.56 (1.51-4.34) P=0.00;GGT OR (95% CI):2.66 (1.53-4.65) P=0.00].Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance.GAO Fei PAN Jie Min HOU Xu Hong FANG Qi Chen LU Hui Juan TANG Jun Ling GU Hui Lin PAN Zhi Jian YAO You Hua SHEN Wei Zhen JIA Wei Ping 2012Biomedical and Environmental Sciences2012,25,1:15
18Shake table test of soil-pile groups-bridge structure interaction in liquefiable ground显示文摘This paper describes a shake table test study on the seismic response of low-cap pile groups and a bridge structure in liquefiable ground.The soil profile,contained in a large-scale laminar shear box,consisted of a horizontally saturated sand layer overlaid with a silty clay layer,with the simulated low-cap pile groups embedded.The container was excited in three E1 Centra earthquake events of different levels.Test results indicate that excessive pore pressure(EPP) during slight shaking only slightly accumulated,and the accumulation mainly occurred during strong shaking.The EPP was gradually enhanced as the amplitude and duration of the input acceleration increased.The acceleration response of the sand was remarkably influenced by soil liquefaction.As soil liquefaction occurred,the peak sand displacement gradually lagged behind the input acceleration;meanwhile,the sand displacement exhibited an increasing effect on the bending moment of the pile,and acceleration responses of the pile and the sand layer gradually changed from decreasing to increasing in the vertical direction from the bottom to the top.A jump variation of the bending moment on the pile was observed near the soil interface in all three input earthquake events.It is thought that the shake table tests could provide the groundwork for further seismic performance studies of low-cap pile groups used in bridges located on liquefiable groun.Tang Liang Ling Xianzhang Xu Pengju Gao Xia Wang Dongsheng 2010Earthquake Engineering and Engineering Vibration2010,9,1:14

20Numerical simulations of shake-table experiment for dynamic soil-pile-structure interaction in liquefi able soils显示文摘A shake-table experiment on pile foundations in liquefi able soils composed of liquefi able sand and overlying soft clay is studied. A three-dimensional(3D) effective stress fi nite element(FE) analysis is employed to simulate the experiment. A recently developed multi-surface elasto-plastic constitutive model and a fully coupled dynamic inelastic FE formulation(u-p) are used to model the liquefaction behavior of the sand. The soil domains are discretized using a solid-fl uid fully coupled(u-p) 20-8 noded brick element. The pile is simulated using beam-column elements. Upon careful calibration, very good agreement is obtained between the computed and the measured dynamic behavior of the ground and the pile. A parametric analysis is also conducted on the model to investigate the effect of pile-pinning, pile diameter, pile stiffness, ground inclination angle, superstructure mass and pile head restraints on the ground improvement. It is found that the pile foundation has a noticeable pinning effect that reduces the lateral soil displacement. It is observed that a larger pile diameter and fi xed pile head restraints contribute to decreasing the lateral pile deformation; however, a higher ground inclination angle tends to increase the lateral pile head displacements and pile stiffness, and superstructure mass seems to effectively infl uence the lateral pile displacements.Tang Liang Baydaa Hussain Maula Ling Xianzhang Su Lei 2014Earthquake Engineering and Engineering Vibration2014,13,1:13
