| 1 | Clinical evaluation of serum interleukin 10 in patients with acute pancreatitis显示文摘OBJECTIVES: To evaluate the behavior of serum interleukin 10 (IL-10) in patients with acutepancreatitis and to explore the relationship between this cytokine and the severity of the disease.METHODS: In 45 patients with acute pancreatitis, the serum concentrations of IL-10 was determinedon days 1, 2, 3, 4, 5 after admission. Twelve healthy subjects were also studied as controls. Thesesubjects were tested using a commercial ELISA kit. The severity of pancreatitis was determined accordingto APACHE Ⅱ score and Balthazar CT criteria.RESULTS: Healthy subjects had no detectable serum levels of IL-10. In acute pancreatitis patients,the serum IL-10 levels were increased on the first day after the onset of the disease and then progressivelydecreased in the following days. On the first day after the onset of acute pancreatitis, the serum levelsof IL-10 in patients with mild acute pancreatitis were significantly higher than in those with severe acutepancreatitis. In the following days, however, no statistically significant difference was observed betweenthe two groups.CONCLUSIONS: Serum IL-10 concentration reflects the severity of acute pancreatitis. IL-10 is a usefulvariable for early prediction of the prognosis of acute pancreatitis. The low values of serum IL-10 inpatients with severe acute pancreatitis suggests that there may be altered down-regulation of immunesystem response. An enhanced release of IL-10 may be a method for early treatment of acute pancreatitis. | Xi-Chun Han Ying-Chao Zhang Yu Wang Ming-Ku Jia the Department of Surgery Secoad Hospital, Jilin University, Changchun 130041, China | 2003 | Hepatobiliary & Pancreatic Diseases International2003，2，1： | 16 |

| 3 | Geologic investigation and mapping of the Sinus Iridum quadrangle from Clementine, SELENE, and Chang’e-1 data显示文摘The objectives of lunar satellite remote sensing are to study lunar surface characteristics, inner structure, and its evolution history. The contents of TiO 2 and FeO are assessed from Clementine UV/VIS data for Sinus Iridum. The geologic stratigraphic units and crates are interpreted visually based on SELENE Terrain Camera (TC) images and the spatial resolution of which is up to 10 m. And the geologic ages of different stratigraphic units are calculated by the crater size-frequency distributions measurements. The gravity anomaly is generated from SELENE gravity model (SGM90d) to show its difference from Mare Imbrium. Furthermore, the thickness of lunar regolith is also derived from microwave radiometer data of Chang’e-1 satellite. Integrating these results, it shows that the Sinus Iridum is different from the Mare Imbrium in inner structure and surface sedimentation. And its history of subsidence, deposition, volcanism, and impact is described. It makes sense to the future soft-landing and sampling at potential Sinus Iridum by remote sensing geologic analysis. | CHEN ShengBo , MENG ZhiGuo, CUI TengFei, LIAN Yi, WANG JingRan & ZHANG XuQing College of Geoexploration Science and Technology, Jilin University, Changchun 130026, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 10 |
| 4 | Tectonic setting of the Helong Block:Implications for the northern boundary of the eastern North China Craton显示文摘LA-ICP-MS zircon U-Pb dating indicates that the Bailiping granitic pluton was em-placed during Late Paleozoic to Early Cretaceous (285―116 Ma) by four distinct magmatic epi-sodes, arguing against the previous thought that the Bailiping granites were emplaced during Archean, Proterozoic or Early Paleozoic. It is suggested that the so-called Archean Jincheng-dong granite-greenstone belt, mainly composed of Bailiping granites, should be broken down. Sr-Nd isotopic compositions of the Bailiping granites are similar to those of the Phanerozoic granites in the Xing’an-Mongolian orogenic belt, suggesting that their parental magmas were mainly derived from a juvenile crust with some contamination of ancient crustal materials during magma rising and/or emplacement. Therefore, the basement of the Helong Block is similar to that in the northern Xing’an-Mongolian Orogenic Belt, but different from that of the North China Craton. It is proposed that the Archean Jinchengdong complex in this area is probably an exotic slice from the North China Craton, which indicates that the Fu’erhe-Gudonghe Fault, located in northern part of the Helong area, is not the boundary between the North China Craton and the Xing’an-Mongolian Orogenic Belt. The possible boundary should be located further southward more than 50 km and near the Baitoushan volcano. | ZHANG Yanbin1, WU Fuyuan1, ZHAI Mingguo1 & LU Xiaoping1,2 1.

| 5 | Studies on Absorption and Tansport of Limoninoids from Fructus Evodiae in Caco-2 Cell Monolayer Model显示文摘Objective To study the intestinal absorption and transepithelial transport of three limoninoids: evodol (EVO), limonin (LIM), and shihulimonin A (SHIA), isolated from Fructus Evodiae [the unripe fruit of Evodia rutaecarpa and Evodia rutaecarpa var. bodinieri] in the human intestine. Methods The in vitro cultured human colon carcinoma cell line, Caco-2 cell monolayer model, was applied to studying the absorption and transepithelial transport of the three limoninoids from apical (AP) to basolateral (BL) side and from BL to AP side. The three limoninoids were measured by reversed-phase high performance liquid chromatography coupled with ultraviolet absorption detector. Transport parameters and apparent permeability coefficients (Papp) were then calculated and compared with those of Propranolol as a control substance of high permeability and Atenolol as a control substance of poor permeability. Results The Papp value of EVO and LIM from AP to BL side for absorption and transport were 1.78 × 10-5 cm/s and 1.16 × 10-5 cm/s, respectively, which was comparable to that of Propranolol with Papp 2.18 × 10-5 cm/s. Conclusion The absorption and transport of both EVO and LIM are main passive diffusion as the dominating process in Caco-2 cell monolayer model, and they were estimated to be high absorbed compounds. SHIA in Caco-2 cell monolayer model may be involved in metabolism in the transport processes. | YANG Xiu-wei1*, TENG Jie1, ZHAO Bo2, ZHANG Lian-xue2 1.

| 6 | Geochemical research on C-O and Sr-Nd isotopes of mantle-derived rocks from Shandong Province, China显示文摘This paper presents systematic studies on the C-O and Sr-Nd isotopic compositions for Cretaceous Badou carbonatites, Fangcheng basalts, and Jiaodong lamprophyres and Paleozoic Mengyin kimberlites in Shandong Province, China. Paleozoic kimberlites have normal and uniform C-O isotopic compositions with δ13C and δ18O in the range of -4.8‰--7.6‰ and +9.9‰-+13.2‰, respectively. However, Cretaceous three different types of mantle-derived rocks have quite different C-O isotopic compositions, indicating that the mantle sources are probably partially contaminated with organic carbon-bearing crustal materials. These Cretaceous rocks show uniform and EMII-like Sr-Nd isotopic compositions and also indicate that the mantle sources were affected by recycled crustal materials. Comparative studies of C-O and Sr-Nd isotopes reveal that the lithospheric mantle beneath the eastern North China Craton had different isotope characteristics in the Paleozoic, the early Cretaceous, and the Tertiary time. This demonstrates that the lithospheric mantle beneath the region underwent at least twice reconstructions since the Paleozoic. Available data imply that the first reconstruction mainly happened during the Triassic-Jurassic time with gradual changes and the second in the Cretaceous with abrupt changes. Results also show that the early Cretaceous (especially at 120-130 Ma) was perhaps the key period leading to the dramatic change of the Mesozoic geodynamics on the eastern North China Craton. | LIU Jianming, ZHANG Hongfu, SUN Jinggui & YE Jie1.

| 7 | Transitivity, mixing and chaos for a class of set-valued mappings显示文摘Consider the continuous map f: X → X and the continuous map (f-) of K(X)into itself induced by f, where X is a metric space and K(X) the space of all non-empty compact subsets of X endowed with the Hausdorff metric. According to the questions whether the chaoticity of f implies the chaoticity of (f-) posed by Román-Flores and when the chaoticity of f implies the chaoticity of (f-)posed by Fedeli,we investigate the relations between f and (f-) in the related dynamical properties such as transitivity, weakly mixing and mixing etc.And by using the obtained results,we give the satisfied answers to Román-Flores's question and Fedeli's question. | LIAO Gongfu, WANG Lidong & ZHANG Yucheng Institute of Mathematics, Jilin University, Changchun 130012, China Institute of Nonlinear Information Technology, Dalian Nations University, Dalian 116600, China Department of Mathematics, University of Science and Technology of China, Hefei 230026, China | 2006 | Science China Mathematics2006，49，1： | 8 |
| 8 | Numerical simulation on drag reduction of revolution body through bionic riblet surface显示文摘Numerical simulations of flow fields on the bionic riblet and the smooth revolution bodies were performed based on the SST k-ω turbulence model in order to explain the mechanisms of the skin friction drag reduction, base drag reduction on the riblet surface, and flow control behaviors of riblet surface near the wall. The simulation results show that the riblet surface arranged on the rearward of the revolution body can reduce the skin friction drag by 8.27%, the base drag by 9.91% and the total drag by 8.59% at Ma number 0.8. The riblet surface reduces the skin friction drag by reducing the velocity gradient and turbulent intensity, and reduces the base drag by weakening the pumping action on the dead water region which behind the body of revolution caused by the external flow. The flow control behavior on boundary layer shows that the riblet surface can cut the low-speed flow near the wall effectively, and restrain the low-speed flow concentrating in span direction, thus weaken the instability of the low speed steaks produced by turbulent flow bursting. | ZHANG ChengChun1, WANG Jing1,2* & SHANG YanGeng1 1 Key Laboratory of Bionics Engineering, Ministry of Education, Jilin University, Changchun 130022, China 2 College of Agriculture, Department of Physics, Jilin University, Changchun 130062, China | 2010 | Science China(Technological Sciences)2010，53，11： | 8 |
| 9 | Factors impacting nanoindentation testing results of the cuticle of dung beetle Copris ochus Motschulsky显示文摘The cuticle of dung beetle is a layered composite material in micro- or nano-scale. Dung beetle can fly, walk and dig. It can shovel and compact dung of mammals into balls. It use foreleg to walk, midleg and hindleg to hold and impel dung ball. Its two foreleges as digging legs are developed. The factors impacting the nanoindentation testing results of the femur cuticle of forelegs of dung beetle Copris ochus Motschulsky were examined. The nanomechanical test instrument used for the tests was Hysitron nanomechanical system. The results shown that the holding time and loading time are important factors im- pacting the accuracy of such indentation properties as reduced modulus (Er) and the harness ( H ) of the femur cuticle of the forelegs of dung beetle Copris ochus Motschulsky in nanoscale. There exists a threshold holding time of 20 s for the reduced modulus of the femur cuticle. The tests of nanoindentation creep property and the regression analysis of relationship between the depth increment at the maximum load and the time further confirmed the correction of the above threshold holding time. There exist visco-elastic-plastic behaviour and creep phenomenon in the femur cuticle during indenting. Its creep property during the holding procedure at maximum load can be regressed by a general logarithmic equation. The equation fitted by the testing data is ? h = 54.83452 ln(0.00723t +1.00486), where, ? h is the depth increment at the maximum load and t is the time. | TONG Jin , SUN Ji-yu , CHEN Dong-hui , ZHANG Shu-jun 1 1 1 2 1.

| 10 | Optical observations of LIGO source GW 170817 by the Antarctic Survey Telescopes at Dome A,Antarctica显示文摘The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light. | lei hu xuefeng wu igor andreoni michael c.b.ashley jeff cooke xiangqun cui fujia du zigao dai bozhong gu yi hu haiping lu xiaoyan li zhengyang li ensi liang liangduan liu bin ma zhaohui shang tianrui sun n.b.suntzeff charling tao syed a.uddin lifan wang xiaofeng wang haikun wen di xiao jin xu ji yang shihai yang xiangyan yuan hongyan zhou hui zhang jilin zhou zonghong zhu | 2017 | Science Bulletin2017，62，21： | 6 |
| 11 | Anti-wear properties on 20CrMnTi steel surfaces with biomimetic non-smooth units显示文摘In order to gain a sufficient wear resistance for applications, the biomimetic non-smooth units in concave were fabricated on the surfaces of 20CrMnTi steel using a biomimetic laser remelting technology. The diameter and distribution of the concaves were optimized using orthogonal experiment. The microstructures of the biomimetic non-smooth units were examined. The anti-wear behaviors were investigated by the rolling wear test with lubricant. The results of wear tests indicated that the biomimetic surfaces exhibit a higher anti-wear ability than the smooth surfaces. The biomimetic surface with concaves of 250 μm in diameter and transverse distance of 270 μm and longitudinal distance of 400 μm exhibits the best anti-wear property. The enhancement of wear resistance can be mainly attributed to the action of biomimetic non-smooth units and the super fined microstructure and hardness in the biomimetic unit zones. | HU Yong1,2, HAN ZhiWu2*, XU MingXu1 & ZHANG ZhiHui2 1College of Mechanical Science and Engineering, Nanling Campus, Jilin University, Changchun 130025, China 2 Key Laboratory of Bionic Engineering, Ministry of Education, College of Biology and Agriculture Engineering, Nanling Campus, Jilin University, Changchun 130025, China | 2010 | Science China(Technological Sciences)2010，53，11： | 6 |
| 12 | Characterization of 500 Chinese patients with cervical esophageal cancer by clinicopathological and treatment outcomes显示文摘Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients. | Peinan Chen Xueke Zhao Fuyou Zhou Xin Song Shoujia Hu Yan Jin Xianzeng Wang Xuena Han ZongminFan Ran Wang Bei Li Wenli Han Panpan Wang Jilin Li Lixin Wan Liguo Zhang Qide Bao Fubao Chang Yanru Qin Zhiwei Chang Jianwei Ku Haijun Yang Ling Yuan Jingli Ren Xuemin Li Lidong Wang | 2020 | Cancer Biology & Medicine2020，17，1： | 6 |

| 14 | Preparation and Anti-oxidative Effects of Corn Peptides显示文摘Corn peptides(CP) were prepared from zein via proteolysis by means of a type of alkaline protease, Alcalase, at 50 ℃ and pH 8.0. The anti oxidative activity of the hydrolysate was examined. It was found that the anti oxidative activity reached the maximum at the fourth hour of the hydrolysis and then decreased. The effect of the enzyme dosage on the solubility of corn protein, the dependence of hydrolysis time on the degree of the hydrolysis(DH) and molecular weight distribution were examined respectively. 30% DH was controlled on the basis of anti oxidative activity. The hydrolysate was fractionated on a Sephadex G 15 column. The anti oxidative activities were examined for all the fractions. The main fraction for anti oxidative activity was collected and characterized by the methods of amino acid analysis, the measurement of average chain length and etc .. The main M W distribution of the main fraction was 300-600 Daltons. The anti oxidative properties of the small peptides in vitro were studied. It was found that they could inhibit the auto oxidation of pyrogallol and the oxidation of hemoglobin. The hemolysis degree of erythrocyte caused by hydroxyl free radicals was decreased greatly, indicating a protective effect of the anti oxidative peptides on the cell membrane damage of erythrocyte. | XU Li, ZHANG Xue zhong ** , GUO Yi, REN Qiao and WU Xiao xia Key Laboratory for Molecular Enzymology and Engineering of the Ministry of Education, Jilin University, Changchun 130021, P.R.

FSEM, TEM, HRTEM, SAED, XRD, FTIR and Raman, ICPAES, laser particle size analyzer, oxygen and nitrogen analyzer, carbon/sulfur determinator and TG-DSC were employed for the characterization of the morphology, structure, chemical composition and thermal stability of the as-synthesized ZrC samples. The as-synthesized samples demonstrated high purity, low oxygen content and evenly distributed Zr C nano-powders with an average particle size of 50 nm. In addition, the effects of endothermic rate and the possible chemical reaction mechanism were also discussed. | 达奥运 龙飞 WANG Jilin XING Weihong WANG Yang ZHANG Fan 王为民 FU Zhengyi | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，4： | 5 |
| 17 | Influence of Annealing on Properties of ZnO Films Grown via Plasma-enhanced MOCVD显示文摘The structural and the optical properties of ZnO films with high quality grown via plasma-enhanced metal\|organic chemical vapour deposition(MOCVD) on C-plane sapphire substrate were studied. The crystallinity and the optical properties of the films are greatly improved having been annealed in oxygen plasma atmosphere. The structure, the band gap and the binding energy of O 1s electrons, and the molar ratio of O to Zn were determined by X-ray diffraction(XRD), photoluminescence(PL) and X-ray photoelectron scan methods. For both the annealed and the as-grown films, the exciton peak features were observed at room temperature. The band-edge photoluminescence of the annealed film is much stronger than that of the as-grown film, and the exciton peak relating to the deep level at 439 nm disappears. The molar ratio of O to Zn in the annealed film is 0 91, while it is 0 78 for the as-grown film. | ZHAO Bai-jun, DU Guo-tong ** , YANG Hong-jun, WANG Jin-zhong ZHANG Yuan-tao, YANG Xiao-tian, LIU Bo-yang, MA Yan YANG Tian-peng, LIU Da-li, LI Wan-cheng and FANG Xiu-jun College of Electronics and Engineering, Jilin University, Changchun 130023, P.

| 18 | Comprehensive Assessment of Seawater Quality Based on an Improved Attribute Recognition Model显示文摘The attribute recognition model (ARM) has been widely used to make comprehensive assessment in many engineering fields, such as environment, ecology, and economy. However, large numbers of experiments indicate that the value of weight vector has no relativity to its initial value but depends on the data of Quality Standard and actual samples. In the present study, the ARM is enhanced with the technique of data driving, which means some more groups of data from the Quality Standard are selected with the uniform random method to make the calculation of weight values more rational and more scientific. This improved attribute recognition model (IARM) is applied to a real case of assessment on seawater quality. The given example shows that the IARM has the merits of being simple in principle, easy to operate, and capable of producing objective results, and is therefore of use in evaluation problems in marine environment science. | ZHANG Libing CHENG Jilin JIN Juliang JIANG Xiaohong | 2006 | Journal of Ocean University of China2006，5，4： | 4 |
| 19 | Scalable and ultrafast epitaxial growth of single-crystal graphene wafers for electrically tunable liquid-crystal microlens arrays显示文摘The scalable growth of wafer-sized single-crystal graphene in an energy-efficient manner and compatible with wafer process is critical for the killer applications of graphene in high-performance electronics and optoelectronics. Here, ultrafast epitaxial growth of single-crystal graphene wafers is realized on singlecrystal Cu90Ni10(1 1 1) thin films fabricated by a tailored two-step magnetron sputtering and recrystallization process. The minor nickel(Ni) content greatly enhances the catalytic activity of Cu, rendering the growth of a 4 in. single-crystal monolayer graphene wafer in 10 min on Cu90Ni10(1 1 1), 50 folds faster than graphene growth on Cu(1 1 1). Through the carbon isotope labeling experiments, graphene growth on Cu90Ni10(1 1 1) is proved to be exclusively surface-reaction dominated, which is ascribed to the Cu surface enrichment in the Cu Ni alloy, as indicated by element in-depth profile. One of the best benefits of our protocol is the compatibility with wafer process and excellent scalability. A pilot-scale chemical vapor deposition(CVD) system is designed and built for the mass production of single-crystal graphene wafers, with productivity of 25 pieces in one process cycle. Furthermore, we demonstrate the application of single-crystal graphene in electrically controlled liquid-crystal microlens arrays(LCMLA), which exhibit highly tunable focal lengths near 2 mm under small driving voltages. By integration of the graphene based LCMLA and a CMOS sensor, a prototype camera is proposed that is available for simultaneous light-field and light intensity imaging. The single-crystal graphene wafers could hold great promising for highperformance electronics and optoelectronics that are compatible with wafer process. | Bing Deng Zhaowei Xin Ruiwen Xue Shishu Zhang Xiaozhi Xu Jing Gao Jilin Tang Yue Qi Yani Wang Yan Zhao Luzhao Sun Huihui Wang Kaihui Liu Mark H.

| 20 | STUDY ON ELECTRORHEOLOGICAL FLUID DAMPER FOR APPLICATION IN MACHINING CHATTER CONTROL显示文摘The electrorheological fluid(ERF)is a kind of intelligent material with bright prospects for industry applications, which has viscoelastic characteristic under the applied electric field. The dynamic model of a milling system with an ERF damper is established, and the chatter suppression mechanism of the ER effect is discussed theoretically. Both the theoretical study and the experimental investigation show that the additional damping and additional stiffness produced by the ERF increase with the rise in the strength of electric field E, but their influence on the cutting stability is different. Only when both additional damping and additional stiffness cooperate, the milling chatter can be suppressed quickly and effectively. In additional, an ERF damper used on the arbor of horizontal spindle milling machine is developed, and a series of milling chatter control experiments are performed. The experimental results show that the milling chatter can be suppressed effectively by using the ER damper. | Yu Junyi Zhang YongliangWang Maohua Zhou XiaoqinFaculty of Mechanical Scienceand Engineering,Jilin University,Changchun 130025, China | 2003 | Chinese Journal of Mechanical Engineering2003，16，1： | 4 |
