2Immune 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 2009Progress in Natural Science:Materials International2009,19,2:24
3Expert consensus on the use of human serum albumin in critically ill patients显示文摘Introduction Human serum albumin(HSA)is a non-glycosylated,negatively charged,single-chain polypeptide composed of 585 amino acid residues with a relative molecular mass of 66.438 kD.It is synthesized by the liver at a rate of approximately 200 mg·kg^(-1)·day^(-1),with a half-life of 21 days,and subjected to catabolism in the muscles,liver,and kidneys at a rate of 4%per day.[1]Albumin,accounting for 60%of the total plasma protein,has various physiological functions,[2]such as maintaining 70%to 80%of effective plasma colloid osmotic pressure,coordinating vascular endothelial integrity,anti-oxidant and anti-inflammatory activities,maintaining the acidbase balance,and participating in the transport,distribution,and metabolism of a variety of endogenous and exogenous substances.Yue-Tian Yu Jiao Liu Bo Hu Rui-Lan Wang Xiang-Hong Yang Xiu-Ling Shang Gang Wang Chang-Song Wang Bai-Ling Li Ye Gong Sheng Zhang Xin Li Lu Wang Min Shao Mei Meng Feng Zhu You Shang Qiang-Hong Xu Zhi-Xiong Wu De-Chang Chen 2021Chinese Medical Journal2021,,14:22
4Optimal approximation of linear systems by artificial immune response显示文摘This paper puts forward a novel artificial immune response algorithm for op-timal approximation of linear systems. A quaternion model of artificial immune response is proposed for engineering computing. The model abstracts four elements, namely, antigen, antibody, reaction rules among antibodies, and driving algorithm describing how the rules are applied to antibodies, to simulate the process of immune response. Some reaction rules including clonal selection rules, immunological memory rules and immune regulation rules are introduced. Using the theorem of Markov chain, it is proofed that the new model is convergent. The experimental study on the optimal approximation of a stable linear system and an unstable one show that the approximate models searched by the new model have better performance indices than those obtained by some existing algorithms including the differential evolution algorithm and the multi-agent genetic algorithm.GONG Maoguo DU Haifeng JIAO Licheng 2006Science in China(Series F)2006,49,1:21

7Memetic computation based on regulation between neural and immune systems: the framework and a case study显示文摘Lamarckian learning has been introduced into evolutionary computation to enhance the ability of local search. The relevant research topic, memetic computation, has received significant amount of interest. In this study, a novel memetic computational framework is proposed by simulating the integrated regulation between neural and immune systems. The Lamarckian learning strategy of simulating the unidirectional regulation of neural system on immune system is designed. Consequently, an immune memetic algorithm based on the Lamarckian learning is proposed for numerical optimization. The proposed algorithm combines the advantages of immune algorithms and mathematical programming, and performs well in both global and local search. The simulation results based on ten low-dimensional and ten high-dimensional benchmark problems show that the immune memetic algorithm outperforms the basic genetic algorithm-based memetic algorithm in solving most of the test problems.GONG MaoGuo , JIAO LiCheng, LIU Fang & YANG Jie Key Lab of Intelligent Perception and Image Understanding of Ministry of Education of China, Institute of Intelligent Information Processing, Xidian University, Xi’an 710071, China 2010Science China(Information Sciences)2010,53,8:16
8ABNORMAL FLOWER AND GRAIN 1 encodes OsMADS6 and determines palea identity and affects rice grain yield and quality显示文摘The palea and lemma are floral organ structures unique to grasses;these structures form the hull and directly affect grain size and quality. However, the molecular mechanisms controlling the development of the hull are not well understood. In this study, we characterized the rice(Oryza sativa) abnormal flower and grain1(afg1) mutant, a new allele of OsMADS6. Similar to previously characterized osmads6 alleles, in the afg1 floret, the palea lost its marginal region and acquired the lemma identity. However, in contrast to other osmads6 alleles, the afg1 mutant showed altered grain size and grain quality, with decreased total starch and amylose contents, and increased protein and soluble sugar contents. The analysis of transcriptional activity suggested that AFG1 is a transcriptional activator and may affect grain size by regulating the expression levels of several genes related to cell expansion and proliferation in the afg1 mutant. These results revealed that AFG1 plays an important role in determining palea identity and affecting grain yield and quality in rice.Xiaoqi Yu Saisai Xia Qiankun Xu Yuanjiang Cui Ming Gong Dali Zeng Qiang Zhang Lan Shen Guiai Jiao Zhenyu Gao Jiang Hu Guangheng Zhang Li Zhu Longbiao Guo Deyong Ren Qian Qian 2020Science China(Life Sciences)2020,63,2:10
9Enhanced aromatic selectivity by the sheet-like ZSM-5 in syngas conversion显示文摘Aromatics are important basic chemicals. However, direct conversion of syngas via the conventional Fischer-Tropsch synthesis produces little aromatics. We presented herein that a bifunctional composite of ZSM-5 in combination with Zn Cr Oxcatalyzes syngas conversion to aromatics. Particularly, ZSM-5 crystals with a sheet-like morphology can enhance significantly the aromatization activity. The lower length ratio of the b/a axes of the crystals, the more aromatics form but without influencing the selectivity of small molecules such as CH4 and C2–C4. Since the acid properties and the Al chemical environment were not altered while the morphology changed, the enhanced aromatic selectivity is likely attributed to the favored diffusion of aromatics in these sheet-like crystals.Junhao Yang Ke Gong Dengyun Miao Feng Jiao Xiulian Pan Xiangju Meng Fengshou Xiao Xinhe Bao 2019Journal of Energy Chemistry2019,28,8:10
10Cerebral mechanism of puncturing at He-Mu point combination for functional dyspepsia: study protocol for a randomized controlled parallel trial显示文摘Acupuncture is widely used to treat functional dyspepsia with satisfactory outcomes. Combination of the He and Mu acupoints is commonly used and has a synergistic effect on functional dyspepsia; however, its underlying mechanisms remain unclear. Therefore, a randomized controlled parallel clinical trial is currently underway at Chengdu University of Traditional Chinese Medicine, China. This trial is designed to explore the efficacy of and central responses to the He-Mu point combination in patients with functional dyspepsia using functional magnetic resonance imaging. A total of 105 patients with functional dyspepsia will be allocated into 3 groups: the low-He point group(puncturing at Zusanli(ST36)), Mu point group(puncturing at Zhongwan(CV12)), and He-Mu point combination group(puncturing at ST36 and CV12). Every participant will receive 20 sessions of manual acupuncture for 4 weeks. The needles will be inserted perpendicularly to a depth of 1 to 2 cun. The angle of rotation and twisting will range from 90 to 180 degrees, while lifting and thrusting will range from 0.3 to 0.5 cm. The various manipulations will be performed 60 to 90 times per minute. The needles will remain in place for 30 minutes, during which manipulation will be applied every 10 minutes. Magnetic resonance imaging will be performed before and after 20 sessions of acupuncture. The primary outcome is symptom improvement according to the Chinese version of the Nepean Dyspepsia Index. Secondary outcomes include the Leeds dyspepsia questionnaire, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Beck Anxiety Inventory, Beck Depression Inventory, and visual analogue scale scores before and after 10 and 20 sessions of acupuncture. Needle sensation and adverse events will be used to assess the therapeutic effects. This study will promote more widespread awareness of the benefits of acupoint combination in the clinical setting and provide a further explanation of the neuromechanism by which acupuncture at the He-Mu point combination for functional dyspepsia.

11CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19.Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen 2020Signal Transduction and Targeted Therapy2020,5,1:9
12Histone deacetylase inhibitor suberoylanilide hydroxamic acid alleviates liver fibrosis by suppressing the transforming growth factor-β1 signal pathway显示文摘Background: Histone deacetylases(HDACs) inhibitors are new anti-fibrotic drugs that inhibit the activity of hepatic stellate cells. The present study focused on the anti-fibrotic function of HDAC inhibitor suberoylanilide hydroxamic acid(SAHA) by suppressing transforming growth factor-β1(TGF-β1) signaling. Methods: Male Sprague-Dawley rats were used to induce liver fibrosis with carbon tetrachloride(CCl 4) and LX2 cell(human hepatic stellate cell line) was stimulated by TGF-β1. Both animals and cells were treated with SAHA. The Smad7 and connective tissue growth factor(CTGF) mRNA levels were detected by real-time polymerase chain reaction(PCR). Western blotting was used to examine the protein levels of CTGF, Histone H3(H3), Smad7, Smad2/3, Acetyl-Histone H3(AH3), HDAC2, α-smooth muscle actin( α-SMA), HDAC6, p-Smad2/3 and HDAC8. In addition, the TGF-β1 and liver enzyme levels from rat serum were detected. Histopathological changes were examined by hematoxylin and eosin(HE), Sirius red and Masson trichrome staining. The α-SMA expression was detected by immumohistochemical staining. Results: Compared with control group, the TGF-β1 and liver enzyme levels from rat serum, together with the mRNA levels of CTGF and protein levels of CTGF, HDAC2, α-SMA, HDAC6, p-Smad2/3 and HDAC8 were elevated in fibrotic rats( P < 0.01). But the Smad7 mRNA and AH3 protein levels were notably suppressed in the fibrotic rats( P < 0.01). Pathological examination showed the typical changes of liver fibrosis in the fibrotic rats. After the treatment with SAHA, the levels of liver enzymes, TGF-β1, CTGF, HDAC2, α-SMA, HDAC6, p-Smad2/3 and HDAC8 were reduced( P < 0.01) and Smad7 and AH3 protein contents were elevated in liver fibrotic rats( P < 0.01). Moreover, immumohistochemistry showed that SAHA significantly suppressed the α-SMA protein content in fibrotic liver( P < 0.01). Conclusion: The HDAC inhibitor SAHA alleviated liver fibrosis by suppressing the TGF-β1 signaling.Yao Wang Lei Zhao Fang-Zhou Jiao Wen-Bin Zhang Qian Chen Zuo-Jiong Gong 2018Hepatobiliary & Pancreatic Diseases International2018,17,5:6
13Multiobjective optimization using an immunodominance and clonal selection inspired algorithm显示文摘Based on the mechanisms of immunodominance and clonal selection theory,we propose a new multiobjective optimization algorithm,immune dominance clonal multiobjective algorithm(IDCMA).IDCMA is unique in that its fitness values of current dominated individuals are assigned as the values of a custom distance measure,termed as Ab-Ab affinity,between the dominated individuals and one of the nondominated individuals found so far.According to the values of Ab-Ab affin-ity,all dominated individuals(antibodies) are divided into two kinds,subdominant antibodies and cryptic antibodies.Moreover,local search only applies to the sub-dominant antibodies,while the cryptic antibodies are redundant and have no func-tion during local search,but they can become subdominant(active) antibodies during the subsequent evolution.Furthermore,a new immune operation,clonal proliferation is provided to enhance local search.Using the clonal proliferation operation,IDCMA reproduces individuals and selects their improved maturated progenies after local search,so single individuals can exploit their surrounding space effectively and the newcomers yield a broader exploration of the search space.The performance comparison of IDCMA with MISA,NSGA-Ⅱ,SPEA,PAES,NSGA,VEGA,NPGA,and HLGA in solving six well-known multiobjective function optimization problems and nine multiobjective 0/1 knapsack problems shows that IDCMA has a good performance in converging to approximate Pareto-optimal fronts with a good distribution.GONG MaoGuo JIAO LiCheng MA WenPing DU HaiFeng 2008Science in China(Series F)2008,51,8:6
14Effect of cream, prepared with Tripterygium wilfordii Hook F and other four medicinals, on joint pain and swelling in patients with rheumatoid arthritis: a double-blinded, randomized, placebo controlled clinical trial显示文摘OBJECTIVE: To investigate the effectiveness a cream onjoint pain and swelling in patients with rheumatoid arthritis(RA). The cream, topically used, in was prepared with Tripterygium wilfordii Hook F(TwHF), Mangxiao(Nalrii Sulfas), Chuanxiong(Rhizoma Chuanxiong), stir-frying with liquid adjuvant Ruxiang(Olibanum), and stir-frying with liquid adjuvant Moyao(Myrrh).METHODS: Patients were 1∶1 randomized to addon TwHF cream twice a day or placebo for 4 weeks.The primary endpoint was achievement rate of20% improvement in American College of Rheuma-tology criteria(ACR20) at week 4. Secondary endpoints were ACR50, 28-joint count Disease Activity Score(DAS28) improvement and safety profiles.Statistical analyses were performed using intention to treat analysis(ITT) set.RESULTS: A total of 70 active RA patients were enrolled. At week 4, the ACR20 was 34.3%(12/35) in TwHF cream group and 11.4%(4/35) in placebo group(P = 0.015). Similarly, a higher ACR50 responder proportion was seen in TwHF cream group with 17.1%(6/35) comparing to it in placebo group with 2.9%(1/35)(P = 0.046). The TwHF cream group also had more improvement than the placebo group on DAS28-ESR(1.1 vs 0.5, P = 0.001), DAS28-CRP(1.4 vs 0.7, P = 0.001), tender joint count(5.5 vs2.6, P = 0.018), swollen joint count(3.5 vs 1.6, P =0.003) and Physician's global assessment(25.8 vs13.0, P = 0.002), as well as C-reactive protein(11.2 vs 2.7, P = 0.048). Except 2 skin allergy events in TwHF cream group, no other substantive adverse events were observed.CONCLUSION: On the short term, TwHF cream is likely to be an effective and safety complimentary treatment in patients with active RA.Jiao Juan Wei Chengchung Tang Xiaopo Gong Xun Yin Haibo Jiang Quan 2019Journal of Traditional Chinese Medicine2019,39,1:6
15Adaptive chaos clonal evolutionary programming algorithm显示文摘Based on the chaos movement and the clonal selection theory, a novel artificial immune system algorithm, Adaptive Chaos Clonal Evolutionary Programming Algorithm (ACCEP), is proposed in this paper. The new algorithm uses the Logistic Sequence to control the mutation scale and uses the Chaos Mutation Operator to control the clonal selection. Compared with SGA and Clonal Selection Algorithm, ACCEP can enhance the precision and stability, avoid prematurity to some extent, and have the high convergence speed. The results of the experiment indicate that ACCEP has the capability to solve complex machine learning tasks, like Multimodal Function Optimization.DU Haifeng GONG Maoguo LIU Ruochen JIAO Licheng 2005Science in China(Series F)2005,48,5:5

17Scale Issues of Wetland Classification and Mapping Using Remote Sensing Images: A Case of Honghe National Nature Reserve in Sanjiang Plain, Northeast China显示文摘Wetland research has become a hot spot linking multiple disciplines presently. Wetland classification and mapping is the basis for wetland research. It is difficult to generate wetland data sets using traditional methods because of the low accessibility of wetlands, hence remote sensing data have become one of the primary data sources in wetland research. This paper presents a case study conducted at the core area of Honghe National Nature Reserve in the Sanjiang Plain, Northeast China. In this study, three images generated by airship, from Thematic Mapper and from SPOT 5 were selected to produce wetland maps at three different wetland landscape levels. After assessing classification accuracies of the three maps, we compared the different wetland mapping results of 11 plant communities to the airship image, 6 plant ecotypes to the TM image and 9 landscape classifications to the SPOT 5 image. We discussed the different characteristics of the hierarchical ecosystem classifications based on the spatial scales of the different images. The results indicate that spatial scales of remote sensing data have an important link to the hierarchies of wetland plant ecosystems displayed on the wetland landscape maps. The richness of wetland landscape information derived from an image closely relates to its spatial resolution. This study can enrich the ecological classification methods and mapping techniques dealing with the spatial scales of different remote sensing images. With a better understanding of classification accuracies in mapping wetlands by using different scales of remote sensing data, we can make an appropriate approach for dealing with the scale issue of remote sensing images.GONG Huili 2011Chinese Geographical Science2011,21,2:5
18Intelligent multi-user detection using an artificial immune system显示文摘Artificial immune systems (AIS) are a kind of new computational intelligence methods which draw inspiration from the human immune system. In this study, we introduce an AIS-based optimization algorithm, called clonal selection algorithm, to solve the multi-user detection problem in code-division multipleaccess communications system based on the maximum-likelihood decision rule. Through proportional cloning, hypermutation, clonal selection and clonal death, the new method performs a greedy search which reproduces individuals and selects their improved maturated progenies after the affinity maturation process. Theoretical analysis indicates that the clonal selection algorithm is suitable for solving the multi-user detection problem. Computer simulations show that the proposed approach outperforms some other approaches including two genetic algorithm-based detectors and the matched filters detector, and has the ability to find the most likely combinations.GONG MaoGuo, JIAO LiCheng, MA WenPing & MA JingJing Key Laboratory of Intelligent Perception and Image Understanding of Ministry of Education of China Institute of Intelligent Information Processing, Xidian University, Xi’an 710071, China 2009Science in China(Series F)2009,52,12:5
19Characterization of increased cuticular wax mutant and analysis of genes involved in wax biosynthesis in Dianthus spiculifolius显示文摘Cuticular wax formation on the surface of plant leaves is associated with drought-stress tolerance.The identification of wax biosynthesis-related genes will contribute to the genetic improvement of drought resistance in plants.In this study,we characterize a novel Dianthus spiculifolius mutant with increased cuticular wax.The mutant exhibited stronger drought resistance as indicated by less leaf wilting and death,higher leaf relative water content and water retention capacity,and slower water loss and chlorophyll extraction than did the wild type during drought treatment.In the mutant leaves,2730 upregulated and 2151 downregulated differentially expressed genes(DEGs)were identified by transcriptome sequencing.A wax biosynthesis pathway of the identified DEGs was significantly enriched.Finally,three key genes(DsCER1,DsMAH1,and DsWSD1)involved in wax biosynthesis were identified and verified by qPCR.These results suggest that differential expression of DEGs involved in wax biosynthesis may be associated with the increase in cuticular wax in the mutant.Taken together,our results help elucidate wax formation patterns in D.spiculifolius.Furthermore,the DEGs involved in wax biosynthesis identified here may be valuable genetic resources for improving plant stress tolerance through increased accumulation of cuticular wax.Aimin Zhou Enhui Liu Jiao Liu Shuang Feng Shufang Gong Jingang Wang 2018Horticulture Research2018,5,1:4
20In situ growth of 3D walnut-like nano-architecture Mo-Ni2P@NiFeLDH/NF arrays for synergistically enhanced overall water splitting显示文摘The in situ growth of nano-array on material structure is a novel and high-efficient strategy to design catalysts,however,it still remains a challenge to fabricate unique nano-architecture electrocatalyst with prominent activity and superior durability for oxygen evolution reaction(OER)and hydrogen evolution reaction(HER).Herein,a unique nano-architecture catalyst is successfully synthesized by using NiFe LDH nanosheets as framework to the in situ growth Mo-doped Ni2 P ultrafine nanosheets(marked as Mo-Ni2 P@NiFe LDH/NF).The unique 3 D core-shell nano-architecture is favorable for enhancing electron transfer/mass diffusion,providing abundant active sites,prompting O2/H2 gas release,and creating the synergistic effect between Mo-Ni2 P and NiFe LDH.Therefore,comparing with pure NiFe LDH/NF and MoNi2 P/NF electrodes,walnut-like Mo-Ni2 P@Ni Fe LDH/NF catalyst exhibits significantly improved electrocatalytic activities and durability towards OER(269 m V@40 m A cm^-2),HER(82 mV@10 mA cm^-2),and overall water splitting(1.46 V@10 m A cm^-2),respectively.Such electrocatalytic activity of Mo-Ni2 P@NiFe LDH/NF is comparable with that of majority reported non-precious metal catalysts and even precious catalysts(IrO2 and Pt/C).This work presents a new perspective strategy to fabricate ingeniously bifunctional electrocatalysts with well-designed structure and superior performance for clean energy conversion technologies or storage devices.Zhi Yang Yu Lin Feixiang Jiao Jinhui Li Jinlei Wang Yaqiong Gong 2020Journal of Energy Chemistry2020,29,10:4
