| 1 | Antioxidation Activities of Low-Molecular-Weight Gelatin Hydrolysate Isolated from the Sea Cucumber Stichopus japonicus显示文摘Gelatin extracted from the body wall of the sea cucumber (Stichopus japonicus) was hydrolyzed with flavourzyme.Low-molecular-weight gelatin hydrolysate (LMW-GH) of 700-1700 Da was produced using an ultrafiltration membrane bioreactor system.Chemiluminescence analysis revealed that LMW-GH scavenges high free radicals in a concentration-dependent manner;IC50 value for superoxide and hydroxyl radicals was 442 and 285 μg mL-1,respectively.LMW-GH exhibited excellent inhibitory characteristics against melanin synthesis and tyrosinase activity in B16 cells.Furthermore,LMW-GH notably increased intracellular glutathione (GSH),which in turn suppressed melanogenesis.LMW-GH performs antioxidation activity,holding the potential of being used as a valuable ingredient in function foods,cosmetics and pharmaceuticals or nutriceuticals. | WANG Jingfeng WANG Yuming TANG Qingjuan WANG Yi CHANG Yaoguang ZHAO Qin XUE Changhu | 2010 | Journal of Ocean University of China2010，9，1： | 13 |
| 2 | Synergistic effect between Sn and K promoters on supported platinum catalyst for isobutane dehydrogenation显示文摘Catalytic dehydrogenation of isobutane has recently received considerable attention because of the increasing demand for isobutene.In this study,the synergistic effect between Sn and K on PtSnK/γ-Al2O3 catalysts has been investigated by changing the content of Sn.It was found that with the presence of potassium,suitable addition of Sn could not only increase the metal dispersion,but also reduce the catalyst acidity.In these cases,the synergistic effect could also strengthen the interactions between the metal and support,which resulted in an increase in both catalytic activity and stability.In our experiments,Pt-0.6SnK/Al catalyst exhibited the lowest deactivation rate (12.4%) and showed a selectivity to isobutene higher than 94% at the isobutane conversion of about 45.3% after running the reaction for 6 h.However,with the excessive loading of Sn,surface property of active sites and the interactions between metal and support were changed.As a result,the initial optimal ratio between the metallic function and acid function would be destroyed,which was disadvantageous to the reaction. | Yiwei Zhang Yuming Zhou Lihui Wan Mengwei Xue Yongzheng Duan Xuan Liu | 2011 | Journal of Natural Gas Chemistry2011，20，6： | 12 |
| 3 | Effect of Ga Addition on Catalytic Performance of PtSnNa/ZSM-5 Catalyst for Propane Dehydrogenation显示文摘PtSnNaGa/ZSM-5 catalysts with different contents of Ga were prepared and characterized by X-ray diffraction (XRD), nitrogen adsorption, hydrogen chemisorption, ammonia temperature-programmed desorption (NH3-TPD), hydrogen temperature-programmed reduction (H2-TPR), and temperature-programmed oxidation (TPO) techniques. The performances of these catalysts for propane dehydrogenation were investigated. The test results indicated that the addition of Ga not only could improve the catalytic stability and propene selectivity, but also could effectively prevent the catalysts from coking. It was found that the PtSnNaGa(0.5 m%)/ZSM-5 catalyst exhibited the best performance in terms of propene selectivity and propane conversion. The high catalytic performance was most probably attributed to the presence of Ga that could strength- en the interaction between metals and the support to stabilize the catalytic active sites. | Liu Xuan Zhou Yuming Zhang Yiwei Duan Yongzheng Xue Mengwei Wan Lihui (School of Chemistry and Chemical Engineering, Southeast University, Nanjing 211189) | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，4： | 7 |
| 4 | Effect of cerium addition on catalytic performance of PtSnNa/ZSM-5 catalyst for propane dehydrogenation显示文摘The effect of cerium addition on the catalytic performance of propane dehydrogenation over PtSnNa/ZSM-5 catalyst has been investigated by reaction tests and some physicochemical characterization such as XRD,BET,TEM,XPS,NH 3-TPD,H 2 chemisorption,TPR and TPO techniques.It has been found that with suitable amount of cerium addition,the platinum dispersion increased,while the carbon deposition tended to be eliminated easily.In these cases,the presence of cerium could not only realize the better distribution of metallic particles on the support,but also strengthen the interactions between Sn species and the support.Additionally,XPS spectra confirmed that more amounts of tin could exist in oxidized form,which was advantageous to the reaction.In our experiments,PtSnNaCe(1.1 wt%)/ZSM-5 catalyst exhibited the best catalytic performance.After running the reaction for 750 h,propane conversion was maintained higher than 30% with the corresponding selectivity to propylene of about 97%. | Mengwei Xue Yuming Zhou Yiwei Zhang Xuan Liu Yongzheng Duan Xiaoli Sheng | 2012 | Journal of Natural Gas Chemistry2012，21，3： | 6 |
| 5 | The absorption kinetics of Antarctic krill oil phospholipid liposome in blood and the digestive tract of healthy mice by single gavage显示文摘Antarctic krill(Euphausia superba)oil has been gaining increasing attention due to its nutritional and functional potentials.Krill oil usually contains a high concentration(about 50%)of phospholipids(AKOP)rich in DHA and EPA accompanied with 30%–40%triacylglycerols.Phospholipids can be made into liposomes without emulsifiers due to its amphiphilic characteristics.However,the absorption kinetics of AKOP liposome in vivo is not clear,which restrict the molecular mechanism analysis related to its distinct bioactivities.The lipid analysis in serum,small intestinal content and wall was carried out after oral administration of AKOP liposome to illustrate its absorption kinetics in blood and the digestive tract of healthy mice by single gavage.The major type of the obtained AKOP was phosphatidylcholine,and the total contents of the DHA and EPA were 29.31%.AKOP liposome was almost completely digested in the small intestine in 1 h and the hydrolysis products could be quickly absorbed by intestinal enterocytes.The DHA in serum peaked at 2 h after administration of AKOP liposome.AKOP liposome could be quickly digested and absorbed in vivo.The obtained results might provide a scientific basis for the molecular mechanism analysis related to distinct bioactivities of Antarctic krill oil phospholipid. | Lin Li Chengcheng Wang Shan Jiang Rong Li Tiantian Zhang Changhu Xue Teruyoshi Yanagita Xiaoming Jiang Yuming Wang | 2020 | Food Science and Human Wellness2020，9，1： | 4 |
| 6 | Propane Dehydrogenation on PtSnNa/AlSBA-15 Catalyst:Influence of Tin as a Promoter显示文摘PtSnNa/AlSBA-15 catalysts with different amounts of Sn were prepared for propane dehydrogenation.The catalysts were characterized by XRF,BET,H2 chemisorption,NH3-TPD,H2-TPR,and TPO techniques.Test results indicated that the presence of tin not only modified the acid function and the interfacial character between metal and support,but also reduced the coke deposition effectively.Among these catalysts investigated thereby,the PtSn(0.7%)Na/AlSBA-15 catalyst had the best catalytic performance in terms of propane conversion and stability.With the continuous addition of Sn,more amounts of Sn0 species appeared,which was unfavorable to the reaction.The PtSn(0.7%)Na/AlSBA-15 catalyst was parametrically characterized in order to obtain necessary information to integrate the process operating conditions.A weight hourly space velocity of 3 h-1,a reaction temperature of 610 ℃ and a H2/C3H8 molar ratio of 0.25 were found to be optimum conditions for achieving a higher dehydrogenation activity of the catalyst. | Duan Yongzheng Zhou Yuming Zhang Yiwei Sheng Xiaoli Xue Mengwei | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，1： | 4 |
| 7 | Effect of Mischmetal Addition on Catalytic Performance of PtSnNa/ZSM-5 for Propane Dehydrogenation显示文摘The influence of mischmetal addition on physicochemical properties of PtSnNa/ZSM-5 catalyst was studied by means of XRF,H 2 chemisorption,XRD,TPR,NH 3-TPD and TPO techniques.The results showed that the presence of mischmetal had an obvious impact on the catalytic performance of the PtSnNa/ZSM-5 catalyst.A suitable content of mischmetal not only could enhance the interactions between Pt species and the support,but also inhibit the formation of coke during the reaction,thus improving the catalytic activity and stability.In our experiments,when the content of mischmetal was 3m%,the catalyst exhibited best catalytic performance.However,the continuous addition of mischmetal could promote the reduction of Sn species to metallic tin,which was disadvantageous to the reaction. | Xue Mengwei Zhou Yuming Huang Li Zhang Yiwei Duan Yongzheng Sheng Xiaoli | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，3： | 4 |

| 9 | Effect of concentration of cadmium sulfate solution on structural,optical and electric properties of Cd_(1-x)Zn_(x)S thin films显示文摘Cd_(1-x)Zn_(x)S thin films were deposited by chemical bath deposition(CBD)on the glass substrate to study the influence of cadmium sulfate concentration on the structural characteristics of the thin film.The SEM results show that the thin film surfaces under the cadmium sulfate concentration of 0.005 M exhibit better compactness and uniformity.The distribution diagrams of thin film elements illustrate the film growth rate changes on the trend of the increase,decrease,and increase with the increase of cadmium sulfate concentration.XRD studies exhibit the crystal structure of the film is the hexagonal phase,and there are obvious diffraction peaks and better crystallinity when the concentration is 0.005 M.Spectrophotometer test results demonstrate that the relationship between zinc content x and optical band gap value E_(g) can be expressed by the equation E_(g)(x)=0.59x^(2)+0.69x+2.43.Increasing the zinc content can increase the optical band gap,and the absorbance of the thin film can be improved by decreasing the cadmium sulfate concentration,however,all of them have good transmittance.At a concentration of 0.005 M,the thin film has good absorbance in the 300-800 nm range,80%transmittance,and band gap value of 3.24 eV,which is suitable for use as a buffer layer for solar cells. | Yuming Xue Shipeng Zhang Dianyou Song Liming Zhang Xinyu Wang Lang Wang Hang Sun | 2021 | Journal of Semiconductors2021，42，11： | 3 |
| 10 | Identification of Five Sea Cucumber Species Through PCR-RFLP Analysis显示文摘Sea cucumbers are traditional marine food and Chinese medicine in Asia. The rapid expansion of sea cucumber market has resulted in various problems, such as commercial fraud and mislabeling. Conventionally, sea cucumber species could be distinguished by their morphological and anatomical characteristics; however, their identification becomes difficult when they are processed. The aim of this study was to develop a new convenient method of identifying and distinguishing sea cucumber species. Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) analysis of mitochondrial cytochrome oxidase I gene(COI) was used to identifing five sea cucumber species(Apostichopus japonicus, Cucumaria frondosa, Thelenota ananas, Parastichopus californicus and Actinopyga lecanora). A 692 bp fragment of COI was searched for BamHI, KpnI, PstI, XbaI and Eco31 I restriction sites with DNAMAN 6.0, which were then used to PCR-RFLP analysis. These five sea cucumber species can be discriminated from mixed sea cucumbers. The developed PCR-RFLP assay will facilitate the identification of sea cucumbers, making their source tracing and quality controlling feasible. | LV Yingchun ZHENG Rong ZUO Tao WANG Yuming LI Zhaojie XUE Yong XUE Changhu TANG Qingjuan | 2014 | Journal of Ocean University of China2014，13，5： | 2 |
| 11 | Long-Term Effects of Docosahexaenoic Acid-Bound Phospholipids and the Combination of Docosahexaenoic Acid-Bound Triglyceride and Egg Yolk Phospholipid on Lipid Metabolism in Mice显示文摘The bioavailability of docosahexaenoic acid(DHA) and eicosapentaenoic acid(EPA) depends on their chemical forms. This study investigated the long-term effects of DHA-bound triglyceride(TG-DHA), DHA-bound phospholipid(PL-DHA), and the combination of TG-DHA and egg yolk phospholipid(Egg-PL) on lipid metabolism in mice fed with a high-fat diet(fat levels of 22.5%). Male C57BL/6J mice were fed with different formulations containing 0.5% DHA, including TG-DHA, PL-DHA, and the combination of TG-DHA and Egg-PL, for 6 weeks. Serum, hepatic, and cerebral lipid concentrations and the fatty acid compositions of the liver and brain were determined. The concentrations of serum total triglyceride(TG), total cholesterol(TC), high-density lipoprotein cholesterol(HDL-c), and hepatic TG in the PL-DHA group and the combination group were significantly lower than those in the high-fat(HF) group(P < 0.05). Atherogenic index(AI) of the PL-DHA group was significantly lower than that of the combination group(P < 0.05). Hepatic TC level in the combination group was significantly lower than that in the HF group(P < 0.05), but no significant difference was observed between the combination group and the PL-DHA group. Both the PL-DHA and the combination groups showed significantly increased DHA levels in the liver compared with the HF group(P < 0.05). However, there were no obvious increases in the cerebral DHA levels in all DHA diet groups. These results suggest that PL-DHA was superior to the combination of TG-DHA and Egg-PL in decreasing the AI. Long-term dietary supplementation with low amount of DHA(0.5%) may improve hepatic DHA levels, although cerebral DHA levels may not be enhanced. | CHE Hongxia CUI Jie WEN Min XU Jie Teruyoshi Yanagita WANG Qi XUE Changhu WANG Yuming | 2018 | Journal of Ocean University of China2018，17，2： | 2 |
| 12 | Catalytic Oxidative Desulfurization of Gasoline Using Vanadium(V)-substituted Polyoxometalate/H_2O_2/Ionic Liquid Emulsion System显示文摘Aiming at deep desulfurization of gasoline,three amphiphilic catalysts [C18H37N(CH3)3]3+x [PMo12-xVxO40](x=1,2,or 3) were prepared and characterized.The amphiphilic vanadium(V)-substituted polyoxometalates were dissolved in water-immiscible ionic liquid([Bmim]PF6),forming a H2O2-in-[Bmim]PF6 emulsion desulfurization system with 30 m% H2O2 serving as the oxidant.The catalytic oxidation of sulfur-containing model oil has been studied in detail under various reaction conditions using this system.The ionic liquid emulsion system showed high catalytic oxidative activity in the treatment of commodity gasoline.Furthermore,the mechanism of catalytic oxidative desulfurization was also elaborated. | Ge Jianhua Zhou Yuming Yang Yong Xue Mengwei | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，1： | 2 |

| 14 | Hpyerglycemic Effect of a Mixture of Sea Cucumber and Cordyceps Sinensis in StreptozotocinInduced Diabetic Rat显示文摘Sea cucumber and cordyceps sinensis are used as both food and traditional medicines in Asia. This study was carried out in order to investigate the hpyerglycemic effect of a mixture of sea cucumber(Apostichopus japonicas) and cordyceps sinensis(Cordyceps militaris)(SCC) in diabetic rat and explore the mechanism underlining such an effect. The diabetic model rat was induced with intraperitoneal injection of streptozotocin(STZ). The diabetic model rats were randomly divided into control group(0.9% NaCl), low dose group(300 mg SCC·(kg body weight)-1) and high dose group(1200 mg SCC(kg body weight)-1). Sodium chloride and SCC were intragastrically administered once a day for 35 d. Changes in fasting serum glucose and serum insulin content, oral glucose tolerance and liver and muscle glycogen content were routinely evaluated. Pancreas tissue and β-cells of islets were observed under both optical and transmission electronic microscope, respectively. The abundance of glucose metabolism-relating genes in gastrocnemius and epididymal adipose tissue was determined with either reverse transcription PCR(RT-PCR) or western blotting. Results showed that SCC significantly decreased fasting serum glucose content, improved glucose tolerance and increased serum insulin and glycogen content; repaired STZ-injured β-cells of diabetic rat, and increased the expression of phosphatidylinositol 3 kinase(PI(3)K), protein kinase B(PKB) and glucose transporter 4(Glut4) encoding protein in both gastrocnemius and adipose tissue, and Glut4 encoding gene in peripheral tissue. Our findings demonstrated that SCC exerted an anti-hyperglycemic effect by repairing β-cells and promoting insulin-mediated signal transduction pathway in insulin-sensitive gastrocnemius and adipose tissue. | HU Shiwei WANG Jingfeng LI Zhaojie FU Jia WANG Yuming XUE Changhu | 2014 | Journal of Ocean University of China2014，13，2： | 1 |
| 15 | Efficient Fe based catalyst with nitrogen doped carbon material modification for propane non-oxidative dehydrogenation显示文摘Nitrogen doped carbon species(NC)was introduced into Fe based catalyst and applied into propane non-oxidative dehydrogenation.With characterizations of XRD,TEM and XPS,it was deduced that the NC modification induces the electrons transferred from NC species to Fe species,leading to electron-rich Fe species.Consequently,propane conversion and propene selectivity were increased by suppressing the by-products formation.It was also confirmed that such a modification strategy could be also extended to ones with different supports,iron precursors,and NC precursors. | Yuming Li Qiyang Zhang Xue Yu Guiling Jiang Yajun Wang Guiyuan Jiang Zhen Zhao Chunming Xu State | 2020 | Carbon Resources Conversion2020，3，1： | 1 |
| 16 | A Comparative Study About the Neuroprotective Effects of EPA-Enriched Phosphoethanolamine Plasmalogen and Phosphatidylethanolamine Against Oxidative Damage in Primary Hippocampal Neurons显示文摘s Oxidative stress is involved in the progression of neurodegenerative diseases.Previous evidences showed that plasma-logens could improve neurodegenerative diseases.In this study,we investigated the function of phosphoethanolamine plasmalogens enriched with EPA(EPA-pPE)and phosphatidylethanolamine enriched with EPA(EPA-PE)on oxidative damage prevention after hy-drogen peroxide(H2O2)and tert-butylhydroperoxide(t-BHP)challenge in primary hippocampal neurons.Results showed that neurons pretreated with EPA-pPE and EPA-PE demonstrated the ability to alleviate oxidative damage,which was proved by the in-creased cell viability.Moreover,the shape and number of neurons were more similar to those of the control group.Antioxidant acti-vity,apoptosis,as well as TrkB/ERK/CREB signaling pathway were investigated to explore the mechanisms.The results suggested that EPA-PE was superior to EPA-pPE in regulating mitochondrial apoptosis.EPA-pPE was more prominent than EPA-PE in upre-gulating TrkB/ERK/CREB signaling pathway.Phospholipids with EPA exerted neuroprotective effects via inhibiting oxidative stress,suppressing apoptosis,and regulating TrkB/ERK/CREB signaling pathway.Therefore,the results provide a scientific basis for utili-zation of phospholipids enriched with EPA on the treatment of neurodegenerative disease. | ZHU Yunfang ZHANG Tiantian DING Lin SHI Haohao XUE Changhu XIE Wancui CHE Hongxia WANG Yuming | 2021 | Journal of Ocean University of China2021，20，5： | 1 |
| 17 | Dietary Supplementation with Sea Cucumber Saponins and Exercise Can Significantly Suppress Adipose Accumulation in Mice Fed with High-Fat Diet显示文摘Dietary supplementation with sea cucumber saponins(SCS)and exercise have been confirmed to be effective in pre-venting the development of obesity and its related diseases.However,the combined effectiveness of these interventions has not been explored.Here,we studied whether the beneficial influences of exercise could be further enhanced by dietary supplementation with SCS in high-fat diet-fed KM(Kunming)mice.Mice were randomly divided into four groups,including the high-fat diet group(HF),the SCS group(HF-S),the exercise group(HF-E),and the combination of dietary SCS and exercise group(HF-S+E).There were eight mice in every group.The results demonstrated that the combination of dietary SCS and exercise could synergistically reduce fat accumulation.In particular,white adipose tissue decreased by 63%in the HF-S+E group compared with that in the HF group.SCS supplementation with exercise also improved peripheral markers,such as serum parameters and hepatic TG levels.Further mechani-cal testing indicated that the combined effects of dietary SCS and exercise on inhibiting fat accumulation might be attributed to the inhibition of lipid synthesis in the liver and the activation of lipolysis in white adipose tissue to increase energy consumption. | LI Rong MENG Jing SHI Haohao WANG Chengcheng LI Zhaojie XUE Changhu WANG Yuming ZHANG Tiantian | 2021 | Journal of Ocean University of China2021，20，3： | 1 |
