| 3 | Immune secondary response and clonal selection inspired optimizers显示文摘The immune system's ability to adapt its B cells to new types of antigen is powered by processes known as clonal selection and affinity maturation. When the body is exposed to the same antigen,immune system usually calls for a more rapid and larger response to the antigen,where B cells have the function of negative adjustment. Based on the clonal selection theory and the dynamic process of immune response,two novel artificial immune system algorithms,secondary response clonal programming algorithm (SRCPA) and secondary response clonal multi-objective algorithm (SRCMOA),are presented for solving single and multi-objective optimization problems,respectively. Clonal selection operator (CSO) and secondary response operator (SRO) are the main operators of SRCPA and SRCMOA. Inspired by the clonal selection theory,CSO reproduces individuals and selects their improved maturated progenies after the affinity mat-uration process. SRO copies certain antibodies to a secondary pool,whose members do not participate in CSO,but these antibodies could be activated by some external stimulations. The update of the secondary pool pays more attention to maintain the population diversity. On the one hand,decimal-string representation makes SRCPA more suitable for solving high-dimensional function optimiza-tion problems. Special mutation and recombination methods are adopted in SRCPA to simulate the somatic mutation and receptor edit-ing process. Compared with some existing evolutionary algorithms,such as OGA/Q,IEA,IMCPA,BGA and AEA,SRCPA is shown to be able to solve complex optimization problems,such as high-dimensional function optimizations,with better performance. On the other hand,SRCMOA combines the Pareto-strength based fitness assignment strategy,CSO and SRO to solve multi-objective optimization problems. The performance comparison between SRCMOA,NSGA-Ⅱ,SPEA,and PAES based on eight well-known test problems shows that SRCMOA has better performance in converging to approximate Pareto-optimal fronts with wide distributions. | Maoguo Gong Licheng Jiao Lining Zhang Haifeng Du | 2009 | Progress in Natural Science:Materials International2009，19，2： | 24 |
| 4 | Blockade of Tim-3 Pathway Ameliorates Interferon-γ Production from Hepatic CD8^+ T Cells in a Mouse Model of Hepatitis B Virus Infection显示文摘T cell immunoglobulin-and mucin-domain-containing molecule-3(Tim-3) has been reported to participate in the pathogenesis of inflammatory diseases. However,whether Tim-3 is involved in hepatitis B virus(HBV) infection remains unknown. Here,we studied the expression and function of Tim-3 in a hydrodynamics-based mouse model of HBV infection. A significant increase of Tim-3 expression on hepatic T lymphocytes,especially on CD8+ T cells,was demonstrated in HBV model mice from day 7 to day 18. After Tim-3 knockdown by specific shRNAs,significantly increased IFN-γ production from hepatic CD8+ T cells in HBV model mice was observed. Very interestingly,we found Tim-3 expression on CD8+ T cells was higher in HBV model mice with higher serum anti-HBs production. Moreover,Tim-3 knockdown influenced anti-HBs production in vivo. Collectively,our data suggested that Tim-3 might act as a potent regulator of antiviral T-cell responses in HBV infection. | Ying Ju Nan Hou Xiaoning Zhang Di Zhao Ying Liu Jinjin Wang Fang Luan Wei Shi Faliang Zhu Wensheng Sun Lining Zhang Chengjiang Gao Lifen Gao Xiaohong Liang Chunhong Ma | 2009 | Cellular & Molecular Immunology2009，6，1： | 19 |

| 7 | Low-FODMAP diet reduces irritable bowel symptoms in patients with inflammatory bowel disease显示文摘AIM To investigate the effect of a low-FODMAP diet on irritable bowel syndrome(IBS)-like symptoms in patients with inflammatory bowel disease(IBD).METHODS This was a randomised controlled open-label trial of patients with IBD in remission or with mild-to-moderate disease and coexisting IBS-like symptoms(Rome III) randomly assigned to a Low-FODMAP diet(LFD) or a normal diet(ND) for 6 wk between June 2012 andDecember 2013. Patients completed the IBS symptom severity system(IBS-SSS) and short IBD quality of life questionnaire(SIBDQ) at weeks 0 and 6. The primary end-point was response rates(at least 50-point reduction) in IBS-SSS at week 6 between groups; secondary end-point was the impact on quality of life. RESULTS Eighty-nine patients, 67(75%) women, median age 40, range 20-70 years were randomised: 44 to LFD group and 45 to ND, from which 78 patients completed the study period and were included in the final analysis(37 LFD and 41 ND). There was a significantly larger proportion of responders in the LFD group(n = 30, 81%) than in the ND group(n = 19, 46%);(OR = 5.30; 95%CI: 1.81-15.55, P < 0.01). At week 6, the LFD group showed a significantly lower median IBSSSS(median 115; inter-quartile range [IQR] 33-169) than ND group(median 170, IQR 91-288), P = 0.02. Furthermore, the LFD group had a significantly greater increase in SIBDQ(median 60, IQR 51-65) than the ND group(median 50, IQR 39-60), P < 0.01.CONCLUSION In a prospective study, a low-FODMAP diet reduced IBS-like symptoms and increased quality of life in patients with IBD in remission. | Natalia Pedersen Dorit Vedel Ankersen Maria Felding Henrik Wachmann Zsuzsanna Végh Line Molzen Johan Burisch Jens Rikardt Andersen Pia Munkholm | 2017 | World Journal of Gastroenterology2017，23，18： | 15 |

| 10 | Effect of RRS on nitrogen transition and related bacteria in rhizosphere soil显示文摘The biology safety of genetically modified organisms(GMO)has been a topic of considerable public debate in recent years.Parts of the international research on the safety of GMO focus on its effect on soil ecosystem,especially on microbial communities changing and process in soil that are essential to key terrestrial ecosystem functions.This paper studied the dynamic change of soil microbe after cultivating Roundup Ready soybean(RRS)and the effect on biochemical processing of nitrogen cycle. According to the variance analysis,the ammonifying bacteria and nitrifying bacteria quantities of RRS in the rhizosphere soil were much lower than that of other genotype soybeans.The effects of different genotype soybeans on ammoniation intensity and nitrification intensity were remarkable.The nitrification intensity and the nitrifying bacteria had the great positive correlation and sustainable development. | LINing WANG Hongyan | 2007 | Journal of Northeast Agricultural University(English Edition)2007，14，4： | 11 |
| 11 | Ginsenoside Rb1 attenuates activated microglia-induced neuronal damage显示文摘The microglia-mediated inflammatory reaction promotes neuronal damage under cerebral ischemia/hypoxia conditions. We therefore speculated that inhibition of hypoxia-induced microglial activation may alleviate neuronal damage. To test this hypothesis, we co-cultured ginsenoside Rb1, an active component of ginseng, and cortical neurons. Ginsenoside Rb1 protected neuronal morphology and structure in a single hypoxic culture system and in a hypoxic co-culture system with microglia, and reduced neuronal apoptosis and caspase-3 production. The protective effect was observable prior to placing in co-culture. Additionally, ginsenoside Rb1 inhibited levels of tumor necrosis factor-α in a co-culture system containing activated N9 microglial cells. Ginsenoside Rb1 also significantly decreased nitric oxide and superoxide production induced by N9 microglia. Our findings indicate that ginsenoside Rb1 attenuates damage to cerebral cortex neurons by downregulation of nitric oxide, superoxide, and tumor necrosis factor-α expression in hypoxia-activated microglia. | Lining Ke Wei Guo Jianwen Xu Guodong Zhang Wei Wang Wenhua Huang | 2014 | Neural Regeneration Research2014，9，3： | 11 |
| 12 | Evidences of rapid erosion driven by climate in the Yarlung Zangbo (Tsangpo) Great Canyon,the eastern Himalayan syntaxis显示文摘Climate and tectonism are both particularly intense in the Yarlung Zangbo (Tsangpo) Great Canyon in the eastern Himalayan syntaxis,which is characterized by the most rapid landscape evolution of anywhere in the world.Thus,the eastern Himalayan syntaxis is one of the best locations to study the interactions between climate and tectonics.This paper investigates the cooling ages of the Doxong La-Baibung profile using apatite fission track (AFT) dating on 11 bedrock samples at elevations ranging from 4210 to 710 m.There are topographic,climatic,metamorphic,and thermochronological gradients in the profile,providing good conditions to study interactions between climate and tectonics.AFT ages ranged from 4.6±0.6 Ma to 1.7±0.3 Ma,and the mean fission track lengths ranged from 11.0 to 12.4 μm.It was found that the cooling rates revealed by AFT ages increased with decreasing elevation.However,the tendency of the cooling rates revealed by the 40 Ar-39 Ar ages was different from that indicated by the AFT ages.Moreover,for most districts of the eastern Himalayan syntaxis,the compiled AFT age distribution correlates well with the annual average precipitation,indicating the coupling of the cooling and erosion rates of the near-surface rock and precipitation.The geothermal history modeling results indicate an obvious increase in the cooling and erosion rate between 1.0 and 0.5 Ma.This age is consistent with other research findings for this time,when the vapor channel of the Yarlung Zangbo Great Canyon began to take effect.These evidences suggest that climate,especially precipitation,has acting as a key factor influencing the rapid cooling and erosion in the Yarlung Zangbo Great Canyon since 1-0.5 Ma. | YU XiangJiang JI JianQing GONG JunFeng SUN DongXia QING JianChun WANG LiNing ZHONG DaLai ZHANG ZhiCheng | 2011 | Chinese Science Bulletin2011，56，11： | 11 |

| 14 | Characterization of monocarboxylate transporter activity in hepatocellular carcinoma显示文摘AIM: To assess the immunoexpression of hypoxiarelated markers in samples from cirrhosis and primary and metastatic hepatocellular carcinoma(HCC).METHODS: From a total of 5836 autopsies performed at the Pathology Department- University of Sao Paulo School of Medicine Hospital- from 2003 to 2009, 188 presented primary liver tumors. Immunohistochemical reactivity for monocarboxylate transporters(MCTs)-1, 2 and 4, CD147 and glucose transporter-1(GLUT1)was assessed in necropsies from 80 cases of HCC. Data were stored and analyzed using the IBM SPSS statistical software(version 19, IBM Company, Armonk, NY). All comparisons were examined for statistical significance using Pearson's χ2 test and Fisher's exact test(when n < 5). The threshold for significant P values was established as P < 0.05.RESULTS: Plasma membrane expression of MCT4 and overall expression of GLUT1 showed progressively higher expression from non-neoplastic to primary HCC and to metastases. In contrast, overall expression of MCT2 was progressively decreased from non-neoplastic to primary HCC and to metastases. MCT1(overall and plasma membrane expression), MCT2 and CD147 plasma membrane expression were associated with absence of cirrhosis, while plasma membrane expression of CD147 was also associated with absence of HBV infection. MCT2 overall expression was associated with lower liver weight, absence of metastasis and absence of abdominal dissemination. Additionally, MCT4 plasma membrane positivity was strongly associated with Ki-67 expression. CONCLUSION: MCT4 and GLUT1 appear to play a role in HCC progression, while MCT2 is lost during progression and associated with better prognosis. | Venncio AF Alves Céline Pinheiro Filipa Morais-Santos Aloisio Felipe-Silva Adhemar Longatto-Filho Fátima Baltazar | 2014 | World Journal of Gastroenterology2014，20，33： | 11 |
| 15 | Design of a control system for a macro-micro dual-drive high acceleration high precision positioning stage for IC packaging显示文摘A macro-micro dual-drive positioning system showing good potential for high acceleration and high precision positioning required in IC packaging applications is devised in this paper. The dual-drive positioning stage uses a VCM (voice coil motor) driven macro positioning stage and a PZT piezo-electric driven micro positioning stage. The coupling characteristics of the system are analyzed to produce a control structure with a micro positioning stage that can dynamically compensate for the positioning error produced by the macro positioning stage. Models of the two positioning stages are described. The models cover both the mechanism and the actuator. For the macro positioning stage, friction characteristics are taken into account, and a controller with an LQG (linear-quadratic-Gaussian) control algorithm combining a feed-forward compensation algorithm is derived. A PID controller is used to control the micro positioning stage. Detailed designs are derived for the proposed approach, and the performance is validated by simulation. | LIU YanJie LI Teng SUN LiNing | 2009 | Science China(Technological Sciences)2009，52，7： | 10 |
| 16 | Recent progress of energy transfer and luminescence intensity boosting mechanism in Nd3+-sensitized upconversion nanoparticles显示文摘Rare earth doped upconversion nanoparticles can be considered as the spice of research in the field of luminescence nanomaterials due to their unique optical properties such as near-infrared excitation.Enormous works have been reported about biomedical applications of 980 nm excited and Yb^3+-sensitized upconversion nanoparticles.However,980 nm excitation wavelength overlaps with the absorption band of water molecules in the biological environment,leading to overheating effect that can induce thermal damages of normal cells and tissues.Recently,Nd^3+-sensitized upconversion nanoparticles which can be excited with 808 nm has been widely investigated as alternative nanoparticles that can surmount this issue of overheating effect.Even though Nd^3+-sensitized upconversion nanoparticles can reduce the overheating effect by 20 fold as compared to Yb^3+-sensitized counterpart,there are several factors that reduce the upconversion luminescence intensity.In this review article,photon energy harvesting and transferring mechanisms in Nd^3+,Yb^3+and emitter ions co-doped upconversion nanoparticles under 808 nm excitation are briefly discussed.Factors that affect upconversion luminescence intensity and quantum yield of Nd^3+-sensitized upconversion nanoparticles are also addressed.Besides,some of the important strategies that have been recently utilized to boost upconversion luminescence intensity of Nd^3+sensitized upco nversion nanoparticles are tho roughly summarized.Lastly,the future challenges in the area and our perspectives are in sight. | Solomon Tiruneh Dibaba Xiaoqian Ge Wei Ren Lining Sun | 2019 | Journal of Rare Earths2019，37，8： | 9 |

| 19 | Stem cell treatment and cerebral palsy: Systemic review and meta-analysis显示文摘BACKGROUND Perinatal complications may result in life-long morbidities,among which cerebral palsy(CP)is the most severe motor disability.Once developed,CP is a nonprogressive disease with a prevalence of 1-2 per 1000 live births in developed countries.It demands an extensive and multidisciplinary care.Therefore,it is a challenge for our health system and a burden for patients and their families.Recently,stem cell therapy emerged as a promising treatment option and raised hope in patients and their families.AIM The aim is to evaluate the efficacy and safety of stem cell treatment in children with CP using a systematic review and meta-analysis METHODS We performed a systematic literature search on PubMed and EMBASE to find randomized controlled clinical trials(RCT)investigating the effect of stem cell transplantation in children with CP.After the review,we performed a randomeffects meta-analysis focusing on the change in gross motor function,which was quantified using the gross motor function measure.We calculated the pooled standardized mean differences of the 6-and/or 12-mo-outcome by the method of Cohen.We quantified the heterogeneity using the I-squared measure.RESULTS We identified a total of 8 RCT for a qualitative review.From the initially selected trials,5 met the criteria and were included in the meta-analysis.Patients’population ranged from 0.5 up to 35 years(n=282).We detected a significant improvement in the gross motor function with a pooled standard mean difference of 0.95(95%confidence interval:0.13-1.76)favoring the stem cell group and a high heterogeneity(I2=90.1%).Serious adverse events were rare and equally distributed among both intervention and control groups.CONCLUSION Stem cell therapy for CP compared with symptomatic standard care only,shows a significant positive effect on the gross motor function,although the magnitude of the improvement is limited.Short-term safety is present and further highquality RCTs are needed. | Simone Eggenberger Céline Boucard Andreina Schoeberlein Raphael Guzman Andreas Limacher Daniel Surbek Martin Mueller | 2019 | World Journal of Stem Cells2019，11，10： | 8 |
| 20 | Studies on the regional feature of organic carbon in sediments off the Huanghe River Estuary waters显示文摘Organic carbon (OC) in definitely small area sediments(according to marine dimension)off the Huanghe River Estuary is investigated in order to evaluate the feature of regional difference of physical and chemical properties in marginal sea sediments.The distributions of OC in sediments with natural grain size and the relationship with the pH,Eh ,Es and Fe3+/Fe2+ are discussed.In addition,OC decomposition rates in surfacial/subsurfacial sediments are estimated.OC concentrations range from 0.26% to 1.8%(wt)in the study area. Significant differences in OC content and in horizontal distribution as well as various trends in surfacial /subsurfacial sediments exhibit the feature of regional difference remarkably in marginal sea sediments. The complicated distribution of OC in surface sediments is due to the influence of bacterial activity and abundance, bioturbation of benthos and physical disturbance. The OC decomposition rate constant in surfacial /subsurfacial sediments ranges from 0.009 7 to 0.076 a-1 and the relatively high values may be mainly related to bacteria that are mainly responsible for OC mineralization;meio-and macrofauna affect OC degradation both directly, through feeding on it, and indirectly through bioturbation and at the same time coarse sediments are also disadvantageous to OC preservation.In almost all the middle and bottom sediments the contents of OC decrease with the increase of deposition depth, which indicates that mineralization of OC in the middle and bottom sediments has occurred via processes like SO reduction and Fe-oxide reduction. | YUANHuamao LIUZhigang SONGJinming LüXiaoxia LIXuegang LINing ZHANTianrong | 2004 | Acta Oceanologica Sinica2004，23，1： | 8 |
