2Prognostic value of intracranial pressure monitoring for the management of hypertensive intracerebral hemorrhage following minimally invasive surgery显示文摘BACKGROUND:The incidence of hypertensive intracerebral hemorrhage(HICH)has been increasing during the recent years in low-and middle-income countries.With high mortality and morbidity rates,it brings huge burden to the families.It lacks evidence regarding the application of intracranial pressure(ICP)monitoring in HICH.In the current study,the authors aimed to evaluate whether ICP monitoring could make any difference on the prognosis of HICH patients after minimally invasive surgery.METHODS:A retrospective review of 116 HICH patients admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine,between 2014 and 2016,was performed.The effects of ICP monitoring on 6-month mortality and favorable outcomes were evaluated by univariate and logistic regression analysis.RESULTS:ICP monitors were inserted into 50 patients.Patients with ICP monitoring had a significantly better outcome(P<0.05).The average in-hospital duration in patients with ICP monitoring was shorter than that in the patients without ICP monitoring(16.68 days vs.20.47 days,P<0.05).Mortality rates between ICP monitoring and no ICP monitoring did not differ significantly(16.0%vs.15.1%,P=0.901).On univariate analysis,age,Glasgow Coma Scale(GCS)on admission and presence of ICP monitor were independent predictors of 6-month favorable outcomes.CONCLUSION:ICP monitoring is associated with a better 6-month functional outcome compared with no ICP monitoring.Future study is still needed to confirm our results and elucidate which subgroup of HICH patients will benefit most from the minimally invasive surgical intervention and ICP monitoring.Xiao-ru Che Yong-jie Wang Hai-yan Zheng 2020World Journal of Emergency Medicine2020,11,3:41
3Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants.Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He 2021National Science Review2021,8,2:47
4Effects of dietary Clostridium butyricum supplementation on growth performance,intestinal development,and immune response of weaned piglets challenged with lipopolysaccharide显示文摘Background: Weanling pigs, with immature immune system and physiological function, usually experience postweaning diarrhea. This study determined the effects of dietary Clostridium butyricum supplementation on growth performance, diarrhea, and immunity of weaned pigs challenged with lipopolysaccharide(LPS).Methods: In Experiment(Exp.) 1,144 weaned piglets were weaned at 21 d and randomly assigned to six groups,with six replicates per group and four pigs per replicate, receiving a control diet(CON) or diet supplemented with antibiotics(AB) or C. butyricum(CB)(0.1%, 0.2%, 0.4%, or 0.8%), respectively. All diets in Exp. 1 were a highly digestible basal diet, with 3,000 mg/kg zinc oxide supplied in the first 2 wk only. In Exp. 2, 180 piglets were weaned at 21 d and randomly assigned to five groups, with six replicates per group and six pigs per replicate, receiving CON, AB, or CB(0.2%, 0.4%, or 0.6%) diets. The digestibility of diets was lower than those in Exp. 1, and did not include zinc oxide. At 36 d of Exp. 2, 12 piglets were selected from each of the CON and 0.4% CB groups, six piglets were intraperitoneally injected with LPS(50 μg/kg body weight) and the other six piglets with normal saline;animals were killed at 4 h after injection to collect blood, intestine, and digesta samples for biochemical analysis.Results: In Exp. 1, CB and AB diets had no effect on growth performance of piglets. In Exp. 2, 0.4% CB decreased feed-gain ratio(P < 0.1), diarrhea score(P < 0.05), and increased duodenal, jejunal, and ileal villus height and jejunal villus height/crypt depth(P < 0.05). The 0.4% CB decreased the plasma tumor necrosis factor(TNF) α(P < 0.05) but increased ileal mucosa IL-10 and TLR2 mRNA expression(P < 0.05). Furthermore, 0.4% CB altered the microbial profile, with Bacillus and Ruminococcaceae UGG-003 at genus level and Lactobacillus casei and Parasutterella secunda at species level were higher than CON in colonic content(P < 0.05).Conclusions: Dietary C. butyricum supplementation had positive effects on growth of weaned piglets with less digestible diets. There was a tendency to reduce the feed-gain ratio, which could reduce feed costs in pig production. Moreover, C. butyricum decreased post-weaning diarrhea by improving the intestinal morphology,intestinal microflora profile, and immune function.Ling Chen Shuang Li Jie Zheng Wentao Li Xuemei Jiang Xilun Zhao Jian Li Lianqiang Che Yan Lin Shengyu Xu Bin Feng Zhengfeng Fang De Wu 2018Journal of Animal Science and Biotechnology2018,9,4:26
5Integral stormwater management master plan and design in an ecological community显示文摘Urban stormwater runoff nearly discharges directly into bodies of water through gray infrastructure in China,such as sewers,impermeable ditches,and pump stations.As urban flooding,water shortage,and other environment problems become serious,integrated water environment management is becoming increasingly complex and challenging.At more than 200 ha,the Oriental Sun City community is a large retirement community located in the eastern side of Beijing.During the beginning of its construction,the project faced a series of serious water environment crises such as eutrophication,flood risk,water shortage,and high maintenance costs.To address these issues,an integral stormwater management master plan was developed based on the concept of low impact development(LID).A large number of LID and green stormwater infrastructure(GSI)approaches were designed and applied in the community to replace traditional stormwater drainage systems completely.These approaches mainly included bioretention(which captured nearly 85th percentile volume of the annual runoff in the site,nearly 5.4×105m3annually),swales(which functioned as a substitute for traditional stormwater pipes),waterscapes,and stormwater wetlands.Finally,a stormwater system plan was proposed by integrating with the gray water system,landscape planning,an architectural master plan,and related consultations that supported the entire construction period.After more than 10 years of planning,designing,construction,and operation,Oriental Sun City has become one of the earliest modern large-scale LID communities in China.Moreover,the project not only addressed the crisis efficiently and effectively,but also yielded economic and ecological benefits.Wu Che Yang Zhao Zheng Yang Junqi Li Man Shi 2014Journal of Environmental Sciences2014,26,9:13
6Selective leaching of vanadium from V-Ti magnetite concentrates by pellet calcification roasting-H_(2)SO_(4) leaching process显示文摘A novel method of pellet calcification roasting-H_(2)SO_(4) leaching was proposed to efficiently separate and extract vanadium(V)from vanadium-titanium(V-Ti)magnetite concentrates.The leaching rate of V is as high as 88.98%,while the leaching rate of impurity iron is only 1.79%.Moreover,the leached pellets can be used as raw materials for blast furnace ironmaking after secondary roasting.X-ray photoelectron spectroscopy(XPS)and scanning electron microscopy with energy dispersive X-ray spectrometry(SEMEDS)analyses showed that V^(3+)was oxidized to V^(5+)after roasting at 1200℃,and V^(5+)was then leached by H_(2)SO_(4).X-ray diffraction(XRD)analyses and single factor experiment revealed a minimal amount of dissolved Fe_(2)O_(3) during H_(2)SO_(4) leaching.Therefore,a high separation degree of V and iron(Fe)from V-Ti magnetite concentrate was achieved through H_(2)SO_(4) leaching.Compared with the traditional roastingleaching process,this process can achieve a high selectivity of V and Fe,and has excellent prospects for industrial production.Yi Luo Xiaokui Che Xinglan Cui Qi Zheng Lei Wang 2021International Journal of Mining Science and Technology2021,31,3:8
7Variability in the composition and export of silica in the Huanghe River Basin显示文摘Concentrations of suspended particle material(SPM), dissolved silicate(DSi), biogenic silica(BSi), phytoliths(plant produced siliceous microscopic structures), and other parameters were analyzed to examine the influence of both natural processes and human activities on silica delivery to the estuary of the Huanghe River(Yellow River). Our results indicate that the concentrations of DSi in the river decreased significantly since 1986. Approximately 34% of dissolved silica was trapped in the basin between 1986 and 2010 due to a reduction of soil erosion. Phytoliths comprised 67.2%–96.3% of BSi, with the smoothing bar type being the dominant form. Concentrations of BSi are significantly higher in the Huanghe River compared to other major rivers throughout the world due to its high sediment yield. We also found that the ratios of BSi/(BSi+DSi) and BSi/SPM were approximately 0.5 and 0.003 at Lijin near the river mouth, indicating that BSi carried in suspension by the Huanghe River was an important component of the rivers silica load. Significant amounts of BSi were also composed of phytoliths in Bohai Sea sediments near the Huanghe River estuary with the smoothing bar form again being the most abundant. The relatively high specific fluxes of BSi in the Huanghe River reflect its high turbidity and high erosion rates in the basin. The high sediment load originating on the Loess Plateau is likely responsible for the higher BSi flux, in agreement with a general trend of increasing BSi flux with increasing sediment flux in global river systems. This study demonstrates that BSi transported by rivers can be composed largely of phytoliths originating from the erosion of topsoils. The flux of phytoliths in river's suspended sediment load may therefore represent a significant contribution to the biogeochemical cycle of silica in coastal waters.RAN XiangBin CHE Hong ZANG JiaYe YU YongGui LIU Sen ZHENG LiLi 2015Science China Earth Sciences2015,58,11:7
8An individualized immune signature of pretreatment biopsies predicts pathological complete response to neoadjuvant chemoradiotherapy and outcomes in patients with esophageal squamous cell carcinoma显示文摘No clinically available biomarkers can predict pathological complete response(pCR)for esophageal squamous cell carcinomas(ESCCs)with neoadjuvant chemoradiotherapy(nCRT).Considering that antitumor immunity status is an important determinant for nCRT,we performed an integrative analysis of immune-related gene profiles from pretreatment biopsies and constructed the first individualized immune signature for pCR and outcome prediction of ESCCs through a multicenter analysis.During the discovery phase,14 differentially expressed immune-related genes(DEIGs)with greater than a twofold change between pCRs and less than pCRs(Chaoqi Zhang Guochao Zhang Nan Sun Zhen Zhang Liyan Xue Zhihui Zhang Haijun Yang Yuejun Luo Xiaoli Zheng Yonglei Zhang Yufen Yuan Ruixue Lei Zhaoyang Yang Bo Zheng Le Wang Yun Che Feng Wang Sihui Wang Shugeng Gao Qi Xue Yi Zhang Jie He 2020Signal Transduction and Targeted Therapy2020,5,1:7
9Down-regulation of eIF5A-2 prevents epithelial-mesenchymal transition in non-small-cell lung cancer cells显示文摘Background:Epithelial-mesenchymal transition(EMT) is believed to be the critical process in malignant tumor invasion and metastases,and has a great influence on improving the survival rate in non-small-cell lung cancer(NSCLC) patients.Recent studies suggested that eukaryotic initiation factor 5A-2(eIF5A-2) might serve as an adverse prognostic marker of survival.We detected eIF5A-2 in NSCLC A549 cells,and found that the invasive capability correlates with the eIF5A-2 expression.Methods:Transforming growth factor(TGF)-β1 was used to induce EMT in A549 cells.Western blotting,immunofluorescence,wound healing assay,and transwell-matrigel invasion chambers were used to identify phenotype changes.Western blotting was also used to observe changes of the expression of eIF5A-2.We down-regulated the eIF5A-2 expression using an eIF5A-2 siRNA and identified the phenotype changes by western blotting and immunofluorescence.We tested the change of migration and invasion capabilities of A549 cells by the wound healing assay and transwell-matrigel invasion chambers.Results:After stimulating with TGF-β1,almost all A549 cells changed to the mesenchymal phenotype and acquired more migration and invasion capabilities.These cells also had higher eIF5A-2 protein expression.Down-regulation of eIF5A-2 expression with eIF5A-2 siRNA transfection could change the cells from mesenchymal to epithelial phenotype and decrease tumor cell migration and invasive capabilities significantly.Conclusions:The expression of eIF5A-2 was up-regulated following EMT phenotype changes in A549 cells,which correlated with enhanced tumor invasion and metastatic capabilities.Furthermore,in the A549 cell line,the process of EMT phenotype change could be reversed by eIF5A-2 siRNA,with a consequent weakening of both invasive and metastatic capabilities.Guo-dong XU Xin-bao SHI Le-bo SUN Qing-yun ZHOU Da-wei ZHENG Huo-shun SHI Yong-liang CHE Zi-shan WANG Guo-feng SHAO 2013Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013,14,6:6
10Clinicopathological analysis of metaplastic meningioma: report of 15 cases in Huashan Hospital显示文摘Objective: Metaplastic meningioma is a rare subtype of benign meningiomas, classified as WHO grade I with well prognosis. Here we presented our experiences on 15 cases of metaplastic meningioma, to investigate the clinicopathological features, therapies and prognosis of these cases. Methods: 15 patients underwent surgical treatment for intracranial metaplastic meningioma between 2001 and 2010 at Neurosurgery Department of Huashan Hospital, Shanghai, China. The clinical data, radiological manifestation, treatment strategy, pathological findings and prognosis of all patients were analyzed retrospectively. Results: Among the 15 cases (10 males and 5 females), the age ranged from 22 to 74 years old (the mean age was 50.67-year old). The clinical manifestations include headache, dizziness, seizure attack, vision decrease, and weakness of bilateral lower limbs. All the patients received surgical treatment, combined with radiotherapy in some cases. In the follow-up period, recurrence occurred in 2 cases, of which 1 patient died of other system complications. Conclusions: Metaplastic meningiomas are characterized by focal or widespread mesenchymal differentiation with formation of bone, cartilage, fat, and xanthomatous tissue elements. Surgical removal is the optimal therapy, and the overall prognosis is well. But recurrence may occur in some cases, thus radiotherapy is necessary for such kind of patients.Hailiang Tang Huaping Sun Hong Chen Ye Gong Ying Mao Qing Xie Liqian Xie Mingzhe Zheng Daijun Wang Hongda Zhu Xiaoming Che Ping Zhong Kang Zheng Shiqi Li Weimin Bao Jianhong Zhu Xuanchun Wang Xiaoyuan Feng Xiancheng Chen Liangfu Zhou 2013Chinese Journal of Cancer Research2013,25,1:6
11Microwave ablation of primary breast cancer inhibits metastatic progression in model mice via activation of natural killer cells显示文摘Surgery is essential for controlling the symptoms and complications of stage IV breast cancer.However,locoregional treatment of primary tumors often results in distant progression,including lung metastasis,the most common type of visceral metastasis.As a minimally invasive thermal therapy,microwave ablation(MWA)has been attempted in the treatment of breast cancer,but the innate immune response after MWA has not yet been reported.Using two murine models of stage IV breast cancer,we found that MWA of primary breast cancer inhibited the progression of lung metastasis and improved survival.NK cells were activated after MWA of the primary tumor and exhibited enhanced cytotoxic functions,and the cytotoxic pathways of NK cells were activated.Depletion experiments showed that NK cells but not CD4+or CD8+T cells played a pivotal role in prolonging survival.Then,we found that compared with surgery or control treatment,MWA of the primary tumor induced completely different NK-cell-related cytokine profiles.Macrophages were activated after MWA of the primary tumor and produced IL-15 that activated NK cells to inhibit the progression of metastasis.In addition,MWA of human breast cancer stimulated an autologous NK-cell response.These results demonstrate that MWA of the primary tumor in metastatic breast cancer inhibits metastatic progression via the macrophage/IL-15/NK-cell axis.MWA of the primary tumor may be a promising treatment strategy for de novo stage IV breast cancer,although further substantiation is essential for clinical testing.Muxin Yu Hong Pan Nan Che Li Li Cong Wang Yue Wang Ge Ma Mengjia Qian Jiawei Liu Mingjie Zheng Hui Xie Lijun Ling Yi Zhao Xiaoxiang Guan Qiang Ding Wenbin Zhou Shui Wang 2021Cellular & Molecular Immunology2021,18,9:5
12Recent Advances in Design Strategies and Multifunctionality of Flexible Electromagnetic Interference Shielding Materials显示文摘With rapid development of 5G communication technologies,electromagnetic interference(EMI)shielding for electronic devices has become an urgent demand in recent years,where the development of corresponding EMI shielding materials against detrimental electromagnetic radiation plays an essential role.Meanwhile,the EMI shielding materials with high flexibility and functional integrity are highly demanded for emerging shielding applications.Hitherto,a variety of flexible EMI shielding materials with lightweight and multifunctionalities have been developed.In this review,we not only introduce the recent development of flexible EMI shielding materials,but also elaborate the EMI shielding mechanisms and the index for'green EMI shielding'performance.In addition,the construction strategies for sophisticated multifunctionalities of flexible shielding materials are summarized.Finally,we propose several possible research directions for flexible EMI shielding materials in near future,which could be inspirational to the fast-growing next-generation flexible electronic devices with reliable and multipurpose protections as offered by EMI shielding materials.Junye Cheng Chuanbing Li Yingfei Xiong Huibin Zhang Hassan Raza Sana Ullah Jinyi Wu Guangping Zheng Qi Cao Deqing Zhang Qingbin Zheng Renchao Che 2022Nano-Micro Letters2022,14,5:5

15HrcQ is necessary for Xanthomonas oryzae pv. oryzae HR-induction in non-host tobacco and pathogenicity in host rice显示文摘Bacterial blight, caused by Xanthomonas oryzae pv. oryzae(Xoo), is one of the most destructive diseases of rice(Oryza sativa L.) worldwide. The type III secretion system(T3SS) of Xoo, encoded by the hrp(hypersensitive response and pathogenicity) genes, plays critical roles in conferring pathogenicity in host rice and triggering a hypersensitive response(HR) in non-host plants. To investigate the major genes conferring the pathogenicity and avirulence of Xoo, we previously constructed a random Tn5-insertion mutant library of Xoo strain PXO99A. We report here the isolation and characterization of a Tn5-insertion mutant PXM69. Tn5-insertion mutants were screened on indica rice JG30, which is highly susceptible to PXO99A, by leaf-cutting inoculation.Four mutants with reduced virulence were obtained after two rounds of screening. Among them, the mutant PXM69 had completely lost virulence to the rice host and ability to elicit HR in non-host tobacco. Southern blotting analysis showed a single copy of a Tn5-insertion in the genome of PXM69. PCR walking and sequencing analysis revealed that the Tn5 transposon was inserted at nucleotide position 70,192–70,201 in the genome of PXO99A, disrupting the type III hrc(hrp-conserved) gene hrcQ, the first gene in the D operon of the hrp cluster in Xoo. To confirm the relationship between the Tn5-insertion and the avirulence phenotype of PXM69, we used the marker exchange mutagenesis to create a PXO99Amutant, ΔhrcQ::KAN, in which the hrcQ was disrupted by a kanamycin-encoding gene cassette at the same site as that of the Tn5-insertion. ΔhrcQ::KAN showed the same phenotype as mutant PXM69. Reintroduction of the wild-type hrcQ gene partially complemented the pathogenic function of PXM69. RT-PCR and cellulase secretion assays showed that the Tn5-disruption of hrcQ did not affect transcription of downstream genes in the D operon and function of the type II secretion system. Our results provide new insights into the pathogenic functions of clustered hrp genes in Xoo.Xiaoping Zhang Chunlian Wang Chongke Zheng Jinying Che Yanqiang Li Kaijun Zhao 2013The Crop Journal2013,1,2:4
16Prognostic value of dynamic electroencephalogram in comatose patients with different diseased regions显示文摘BACKGROUND: It has proved that dynamic electroencephalogram (EEG) is definite in judging the outcome of ischemic hypoxic comatose patients, EEG is more sensitive to the cortical affection, but not sensitive to the subcortical and brainstem affections, thus it is necessary to clarify the indications of this technique in the clinical application. OBJECTIVE: To observe and compare the prognostic value of dynamic EEG and Glasgow coma score in comatose patients with different diseased region. DESIGN: A clinical case-controlled observation. SETTING: Union Hospital of Fujian Medical University. PARTICIPANTS: Sixty-eight comatose patients were selected from the Union Hospital affiliated to Fujian Medical University from June 1998 to January 2005. The diseased regions were identified using cranial CT (n =43) or MR (n =25). According to different primarily diseased regions, the comatose patients were divided into two groups: ① brainstem affection group (n =23): 13 males and 10 females, 14–62 years of age; ② diffuse cortical affection group (n =45): 28 males and 17 females, 23–75 years of age. METHODS: The dynamic EEG and Glasgow coma score were examined in the 45 comatose patients with primarily cortical affection and 22 comatose patients with primarily brainstem affection at acute phase. The patients were followed-up for 3 months to observe the outcome, The termination of outcome judgment was 3 months after attack or the death. The clinical outcome was classified as complete rehabilitation, survived with disability, death or vegetative state. Correlations of dynamic EEG and Glasgow coma score with the outcome of patients were analyzed. The correlations of dynamic EEG grades and Glasgow coma scores with the outcome were analyzed, and the prognostic value of dynamic EEG grades was compared between the two groups. MAIN OUTCOME MEASURES: ① Correlations of dynamic EEG and Glasgow coma score with the outcome of patients; ② Comparison of the prognostic value of dynamic EEG grades between the two groups. RESULTS: All the 68 patients were involved in the analysis of results. ① Correlations of dynamic EEG grades and Glasgow scores and their correlation analysis: EEG grades had significant negative correlation with Glasgow coma scores in both the cortical affection group and brainstem affection group (r =–0.743, –0.564, P < 0.01, 0.05). In the cortical affection group, the Glasgow coma scores and dynamic EEG grades in the patients with the outcome of death or vegetative state were significantly different from those with the outcome of rehabilitation (P < 0.05–0.01). In the brainstem affection group, the Glasgow coma scores were only significantly different between the patients with outcome of rehabilitation and death (P < 0.05), and there was no significant difference in dynamic EEG grades among the three prognostic states (P > 0.05). ② Comparison of the prognostic value of dynamic EEG grades between comatose patients with cortical affection and brainstem affection: The sensitivity, specificity and accuracy were all higher (P < 0.05), while the error rate was lower (P < 0.05) in the cortical affection group than in the brainstem affection group. CONCLUSION: Dynamic EEG was valuable in predicting the outcome of comatose patients with primarily cortical affection, but it was not certainly valuable in those with primarily brainstem affection.Huapin Huang Chunhui Che An Zheng Xiaoyun Zhuang Fang Jiang Nan Liu 2007Neural Regeneration Research2007,2,7:4

18Design and optimization of low-energy transfer orbit to Mars with multi-body environment显示文摘This paper discusses the problem of design and optimization of low-energy transfer orbit with multi-body environment. A new integrative method is proposed to effectively solve the problem, in which the parameterized patched manifolds in CR3BP(circular restricted three-body problems), the shape-based method with multi-body environment, the homotopic method with multi-body environment, and the low-thrust capturing and descending algorithm with multi-body environment are all included. Firstly, the parameters describing the patched manifolds in CR3 BP are optimized until the least total absolute velocity increment has been got, including the employment of the shape-based method with multi-body environment. Secondly, the low-thrust control laws of the transfer orbit are optimized employing the homotopic method with multi-body environment that transfers the fuel optimization problem to an easier energy optimization problem. Thirdly, the low-thrust descending orbit around Mars is computed using the laws proposed in this paper. As a typical example, the Earth-Mars transfer orbit design is discussed. The results showed that the parameters describing the patched manifolds could be optimized by the DE(differential evolution) algorithm effectively; the homotopic method with multi-body environment could get the optimal value that meets the first order optimality conditions; and the low-thrust descending orbit could effectively be captured by Mars and finally become a circular parking orbit around it by the hypothesis control laws proposed in this paper. It shows that the final fuel cost is much less than the optimal transfer in the patched two-body problems. In conclusion, the method proposed in this paper could effectively solve the low-energy low-thrust optimal control problem in multi-body environment for the future deep space explorations.LU Yi LI HengNian LI JiSheng CHE Zheng YANG YiKang YANG Yuan SUN Yang 2015Science China(Technological Sciences)2015,58,10:3
