| 2 | Fibroblast growth factor-4 and hepatocyte growth factor induce differentiation of human umbilical cord blood-derived mesenchymal stem cells into hepatocytes显示文摘AIM: To investigate the differentiation of human umbilical cord blood (HUCB)-derived mesenchymal stem cells (MSCs) into hepatocytes by induction of fibroblast growth factor-4 (FGF-4) and hepatocyte growth factor (HGF), and to find a new source of cell types for therapies of hepatic diseases.METHODS: vSCs were isolated by combining gradient density centrifugation with plastic adherence. When HUCB-derived MSCs reached 70% confluence, they were cultured in Iscove modified Dulbecco medium (IMDM) supplemented with 10 mL/L FBS, 20 ng/mL HGF and 10 ng/mL FGF-4. The medium was changed every 4 d and stored for albumin, alpha-fetoprotein (AFP) and urea assay. Expression of CK-18 was detected by immunocytochemistry. Glycogen storage in hepatocytes was determined by PAS staining.RESULTS: By combining gradient density centrifugation with plastic adherence, we could isolate MSCs from 25.6% of human umbilical cord blood. When MSCs were cultured with FGF-4 and HGF, approximately 63.6% of cells became small, round and epithelioid on d 28 by morphology. Compared with the control, the level of AFP increased significantly from d 12 to 18.20±1.16 μg/L (t = 2.884, P<0.05) in MSCs cultured with FGF-4 and HGF, and was higher (54.28±3.11 μg/L) on d 28 (t = 13.493, P<0.01). Albumin increased significantly on d 16 (t = 6.68, P<0.01) to 1.02±0.15 μg/mL, and to 3.63±0.30 μg/mL on d 28 (t = 11.748, P<0.01). Urea(4.72±1.03 μmol/L) was detected on d 20 (t = 4.272,P<0.01), and continued to increase to 10.28±1.06 μmol/L on d 28 (t = 9.276, P<0.01). Cells expressed CK-18 on d 16. Glycogen storage was observed on d 24. CONCLUSION: HUCB-derived MSCs can differentiate into hepatocytes by induction of FGF-4 and HGF. HUCBderived MSCs are a new source of cell types for cell transplantation therapy of hepatic diseases. | Xin-Qin Kang Wei-Jin Zang Li-Jun Bao Dong-Ling Li Tu-Sheng Song Xiao-Li Xu Xiao-Jiang Yu | 2005 | World Journal of Gastroenterology2005，11，47： | 38 |
| 3 | Effect of hepatocyte apoptosis induced by TNF-α on acute severe hepatitis in mouse models显示文摘AIM To study the effect of hepatocyteapoptosis and necrosis induced by TNF-α on thepathogenesis of acute severe hepatitis(ASH).METHODS The model of ASH was prepared inD-galactosamine(GAIN)sensitized BALB/c miceby injection of either endotoxin(ET)or tumornecrosis factor-α(TNF-α).Morphologicalchanges of apoptotic hepatocytes were studiedby both light and electron microscope and in siteend labeling method(ISEL).Molecular biologicalchanges of DNA ladder were observed byelectrophoresis of extract from liver tissues.Biochemical changes were measured by alanineaminotransferase(ALT),asparticaminotransferase(AST)and TNF-α.The relationbetween apoptosis and necrosis was evaluatedsimultaneously.RESULTS The sequence of hepatocyteapoptosis,necrosis,and final death from ASHwas observed both in GAIN/ET and GAIN/TNF-agroup.Apoptosis was prominent at 3.5 h and 5 hafter injection of inducer,while necrosis becamedominant at 9 h after challenge.The appearanceof apoptosis was earlier in GAIN/TNF-α groupthan that in GAIN/ ET group.Pretreatment ofmice with antiTNF IgG1 may completely preventthe liver injury induced by GalN/ET.CONCLUSION TNF-α can cause liver damageby inducing hepatic apoptosis and necrosis inmice with endotoxemia. | Guo Qing Zang Xia Qiu Zhou Hong Yu Qing Xie Guo Ming Zhao Bin Wang Qing Guo Yue Qin Xiang Dan Liao Department of Infectious Diseases,Rujin Hospital,Shanghai Second Medical University,Shanghai 200025,China | 2000 | World Journal of Gastroenterology2000，6，5： | 30 |
| 4 | Prevalence of Thyroid Nodules and Its Relationship with Iodine Status in Shanghai:a Population-based Study显示文摘Objective This study was designed to evaluate the prevalence of thyroid nodules(TNs) and its relationship with urine iodine concentrations(UICs) after the regional rapid economic growth and lifestyle changes. Methods A cross-sectional survey was conducted in the general population aged 15-69 years. A questionnaire regarding general and personal characteristics and relevant information was administered. Ultrasonography of the thyroid was performed, and serum triiodothyronine(T3), tetraiodothyronine(T4), serum thyroid stimulating hormone(TSH), free triiodothyronine(FT3), free tetraiodothyronine(FT4), thyroglobulin antibody(Tg Ab), thyroid peroxidase antibody(TPOAb), and TSH receptor antibody(TRAb) levels were measured for each individual subject. Results The prevalence rates of TNs in the whole population, females and males were 27.76%, 34.04%, and 21.60%, respectively. The prevalence of multiple nodules increased with age, whereas the prevalence peaks differed between males and females. The median UICs in the whole population and females with non-TNs were higher than those of subjects with TNs(P=0.0035, P=0.0068). The median UICs in subjects with a single TN were higher than those in subjects with multiple TNs(P=0.0164, P=0.0127). The result showed a U-shaped curve relationship between UIC and prevalence of TNs. The prevalence of TNs was the lowest when the UIC was 140-400 μg/L. Conclusion The prevalence of TNs was nearly 30% and increased with age. The relationship between UIC and prevalence of TNs is U-shaped, with an increase in risk when the UIC was <140 μg/L and >400 μg/L. Very low or high UIC levels need attention and correction. | SONG Jun ZOU Shu Rong GUO Chang Yi ZANG Jia Jie ZHU Zhen Ni MI Ming HUANG Cui Hua YU Hui Ting LU Xi RUAN Ye WU Fan | 2016 | Biomedical and Environmental Sciences2016，29，6： | 25 |
| 5 | Cell–cell contact with proinflammatory macrophages enhances the immunotherapeutic effect of mesenchymal stem cells in two abortion models显示文摘Mesenchymal stem cells(MSCs),which are pluripotent cells with immunomodulatory properties,have been considered good candidates for the therapy of several immune disorders,such as inflammatory bowel diseases,concanavalin A-induced liver injury,and graft-versus-host disease.The embryo is a natural allograft to the maternal immune system.A successful pregnancy depends on the timely extinction of the inflammatory response induced by embryo implantation,followed by the switch to a tolerant immune microenvironment in both the uterus and the system.Excessive infiltration of immune cells and serious inflammatory responses are triggers for embryo rejection,which results in miscarriage.Here,we demonstrated that adoptive transfer of MSCs could prevent fetal loss in a lipopolysaccharide(LPS)-induced abortion model and immune response-mediated spontaneous abortion model.The immunosuppressive MSCs alleviated excessive inflammation by inhibiting CD4+T cell proliferation and promoting the decidual macrophage switch to M2 in a tumor necrosis factor-stimulated gene-6(TSG-6)-dependent manner.Cell-tocell contact with proinflammatory macrophages increased the TSG-6 production by the MSCs,thereby enhancing the suppressive regulation of T cells and macrophages.Moreover,proinflammatory macrophages in contact with the MSCs upregulated the expression of CD200 on the stem cells and facilitated the reprogramming of macrophages towards an anti-inflammatory skew through the interaction of CD200 with CD200R on proinflammatory macrophages.Therefore,the results demonstrate that a TSG-6-mediated paracrine effect,reinforced by cell-to-cell contact between MSCs and proinflammatory macrophages,is involved in the mechanism of MSC-mediated abortion relief through the induction of immune tolerance.Our study also indicates the potential application of MSCs in clinical recurrent miscarriages. | Yanhong Li Di Zhang Ling Xu Lin Dong Ji Zheng Yikong Lin Jiefang Huang Yanyun Zhang Yu Tao Xingxing Zang Dajin Li Meirong Du | 2019 | Cellular & Molecular Immunology2019，16，12： | 23 |
| 6 | Safety and efficacy of ciprofol vs.propofol for sedation in intensive care unit patients with mechanical ventilation:a multi-center,open label,randomized,phase 2 trial显示文摘Background:Ciprofol(HSK3486;Haisco Pharmaceutical Group Co.,Ltd.,Chengdu,China),developed as a novel 2,6-disubstituted phenol derivative showed similar tolerability and efficacy characteristics as propofol when applicated as continuous intravenous infusion for 12 h maintenance sedation in a previous phase 1 trial.The phase 2 trial was designed to investigate the safety,efficacy,and pharmacokinetic characteristics of ciprofol for sedation of patients undergoing mechanical ventilation.Methods:In this multicenter,open label,randomized,propofol positive-controlled,phase 2 trial,39 Chinese intensive care unit patients receiving mechanical ventilation were enrolled and randomly assigned to a ciprofol or propofol group in a 2:1 ratio.The ciprofol infusion was started with a loading infusion of 0.1-0.2 mg/kg for 0.5-5.0 min,followed by an initial maintenance infusion rate of 0.30 mg·kg^(-1)·h^(-1),which could be adjusted to an infusion rate of 0.06 to 0.80 mg·kg^(-1)·h^(-1),whereas for propofol the loading infusion dose was 0.5-1.0 mg/kg for 0.5-5.0 min,followed by an initial maintenance infusion rate of 1.50 mg·kg^(-1)·h^(-1),which could be adjusted to 0.30-4.00 mg·kg^(-1)·h^(-1)to achieve-2 to+1 Richmond Agitation-Sedation Scale sedation within 6-24 h of drug administration.Results:Of the 39 enrolled patients,36 completed the trial.The median(min,max)of the average time to sedation compliance values for ciprofol and propofol were 60.0(52.6,60.0)min and 60.0(55.2,60.0)min,with median difference of 0.00(95%confidence interval:0.00,0.00).In total,29(74.4%)patients comprising 18(69.2%)in the ciprofol and 11(84.6%)in the propofol group experienced 86 treatment emergent adverse events(TEAEs),the majority being of severity grade 1 or 2.Drug-and sedation-related TEAEs were hypotension(7.7%vs.23.1%,P=0.310)and sinus bradycardia(3.8%vs.7.7%,P=1.000)in the ciprofol and propofol groups,respectively.The plasma concentration-time curves for ciprofol and propofol were similar.Conclusions:ciprofol is comparable to propofol with good tolerance and efficacy for sedation of Chinese intensive care unit patients undergoing mechanical ventilation in the present study setting.Trial registration:ClinicalTrials.gov,NCT04147416. | Yongjun Liu Xiangyou Yu Duming Zhu Jun Zeng Qinhan Lin Bin Zang Chuanxi Chen Ning Liu Xiao Liu Wei Gao Xiangdong Guan | 2022 | Chinese Medical Journal2022，，9： | 19 |
| 7 | CTLA4 Silencing with siRNA Promotes Deviation of Th1/Th2 in Chronic Hepatitis B Patients显示文摘To determine whether RNA interference (RNAi) could block cytotoxic T-lymphocyte antigen 4 (CTLA4) in human lymphocytes in vitro and promote IFN-γ and IL-2 secretions, three small interfering RNAs (siRNAs) were selected based on target specificity sequences of human CTLA4 and transfected into human lymphocytes of chronic HBV patients. As a result, the expression of human CTLA4 mRNA was efficiently suppressed by all the three siRNAs. Compared with negative control (siRNA-co), siRNA-1 inhibited the expression of CTLA4 most efficiently and was used in the further study. The expressions of IFN-γ and IL-2 were upregulated and the level of IL-4 was almost unchanged in lymphocytes transfected with siRNA-1 compared with the blank control. These results indicated that siRNA-1 led to IFN-γ and IL-2 secretions, which is a main response of Th1/Th2. In a conclusion, RNAi significantly suppressed the expression of human CTLA4 mRNA in human lymphocytes in vitro, and could induce Th1/Th2 response. It could be a new therapeutic strategy for chronic HBV infection. | Yongsheng Yu Hao Wu Zhenghao Tang Guoqing Zang | 2009 | Cellular & Molecular Immunology2009，6，2： | 14 |
| 8 | Empirical Research on Carrying Capacity of Human Settlement System in Dalian City, Liaoning Province, China显示文摘Using the theories of population carrying capacity and ecological elasticity in other fields for reference, the connotation of regional human settlement system was defined from the viewpoint of the complex relationship among the factors such as regional population, resources, environment and economic and social development in the context of China′s rapid urbanization. Then the concept and characterization methods of the regional human settlement carrying capacity were proposed by means of population scale. Furthermore, a model of carrying capacity-pressure-state-response(CPSR) on regional human settlement system was established by referencing pressure-state-response(PSR) model, and the Catastrophe Theory was introduced to determine the corresponding standards of multi-criteria programming and evaluation. Taking Dalian City, Liaoning Province, China as an example, an empirical analysis on evaluation of human settlement system from 2000 to 2012 was carried out. The results showed that the carrying capacity of human settlement system in Dalian was fluctuating between 9.6 × 106 to 10 × 106 persons with a quantitative stage of the dynamic regulation. During the research period the load index of human settlement system in Dalian dropped from 0.96 to 0.84 with a lower pressure of human settlement system than the national average level. And the emergency response grades of human settlement system in Dalian were kept in grade Ⅱ(orange warning) or grade Ⅲ(yellow warning). Human settlement system of Dalian was in slight security state as a whole, but the load had a tendency of increase in recent years. The related departments should pay close attention to regional human settlement system and take active measures to improve human settlement by both intensity control and total quantity control. By comparison, analysis and discussion, it was considered that the results were basically accordded with the current situations of human settlement in Dalian, and the evaluation results were more reliable, visualized and easily applied in practice. Therefore, the above-mentioned concepts, characterization and evaluation methods of the regional human settlement system and carrying capacity could provide a new thought and method for quantitative evaluation of human settlement. | ZHENG Defeng ZHANG Yu ZANG Zheng SUN Caizhi | 2015 | Chinese Geographical Science2015，25，2： | 13 |
| 9 | Protective Effect of Hydroxysafflor Yellow A on Inflammatory Injury in Chronic Obstructive Pulmonary Disease Rats显示文摘Objective: To investigate the attenuating effect of Hydroxysafflor yellow A(HSYA) on inflammatory injury in chronic obstructive pulmonary disease(COPD). Methods: Rats were randomly assigned to 7 groups according to body weight including normal control group, HSYA blank group(76.8 mg/kg), COPD group, COPD+HSYA(30, 48, 76.8 mg/kg) groups and COPD+dexamethasone(2 mg/kg), 10 in each group. Passive cigarette smoke and intratracheal instil ation of lipopolysaccharides were used to establish a COPD model in rats. Hematoxylin and eosin staining of lung tissue sections was used, real-time polymerase chain reaction(PCR) was used to assay m RNA levels of some cytokines in lung tissues, the cytokines in bronchoalveolar lavage fluid(BALF) were measured by enzyme-linked immunosorbent assay(ELISA), Western blot analysis was used to determine phosphorylated p38 mitogen-activated protein kinase(MAPK) levels in lung tissues, and nuclear factor-κB(NF-κB) p65 protein levels in lung tissues were detected by immunohistochemistry. Results: Lung alveolar septa destruction, alveolus fusion, inflammatory cel infiltration, and bronchiole exudation were observed. These pathological changes were al eviated in the COPD+HSYA group. The m RNA expression of inflammatory factors were significantly increased in lung tissues from COPD rats(all P<0.01) and were inhibited by HSYA. Levels of inflammatory cytokines in BALF of COPD rats were significantly increased(all P<0.01) which were inhibited by HSYA(all P<0.01, 48, 76.8 mg/kg). The levels of p38 MAPK phosphorylation and p65 in lung tissues of COPD rats were significantly increased(al P<0.01) and were suppressed by HSYA(all P<0.01, 48, 76.8 mg/kg). Conclusions: HSYA could alleviate inflammatory cell infiltration and other pathological changes in the lungs of COPD rats. HSYA could inhibit inflammatory cytokine expression, and increase phosphorylation of p38 MAPK and NF-κB p65 in the lungs of COPD rats. The protective mechanism of HSYA to inhibit COPD inflammation might be by attenuating NF-κB and p38 MAPK signal transduction. | JIN Ming XUE Chang-jiang WANG Yu DONG Fang PENG Yuan-yuan ZHANG Ya-dan ZANG Bao-xia TAN Li | 2019 | Chinese Journal of Integrative Medicine2019，25，10： | 12 |
| 10 | Enhancement of CTLs induced by DCs loaded with ubiquitinated hepatitis B virus core antigen显示文摘AIM:To investigate whether hepatitis B virus (HBV) could induce a hepatitis B virus core antigen (HBcAg)specific cytotoxic T lymphocyte (CTL) response in vitro by dendritic cells (DCs) transduced with lentiviral vector-encoding ubiquitinated hepatitis B virus core antigen (LV-Ub-HBcAg).METHODS:Recombinant LV-Ub-HBcAg were transfected into highly susceptible 293 T cells to obtain high virus titres.Bone marrow-derived DCs isolated from BALB/c mice were cultured with recombinant granulocyte-macrophage colony-stimulating factor and recombinant interleukin (IL)-4.LV-Ub-HBcAg,lentiviral vector-encoding hepatitis B virus core antigen (LV-HBcAg),lentiviral vector (LV) or lipopolysaccharide were added to induce DC maturation,and the DC phenotypes were analyzed by flow cytometry.The level of IL-12 in the supernatant was detected by enzyme-linked immunosorbent assay (ELISA).T lymphocytes were proliferated using Cell Counting Kit-8.DCs were cultured and induced to mature using different LVs,and co-cultured with allogeneic T cells to detect the secretion levels of IL-2,IL-4,IL-10 and interferon-γ in the supernatants of T cells by ELISA.Intracellular cytokines of proliferative T cells were analyzed by flow cytometry,and specific CTL activity was measured by a lactate dehydrogenase release assay.RESULTS:LV-Ub-HBcAg-induced DCs secreted more IL-12 and upregulated the expression of CD80,CD86 and major histocompatibility class Ⅱ.DCs sensitised by different LVs effectively promoted cytokine secretion;the levels of IL-2 and interferon-γ induced by LV-UbHBcAg were higher than those induced by LV-HBcAg.Compared with LV-HBcAg-transduced DCs,LV-UbHBcAg-transduced DCs more efficiently stimulated the proliferation of T lymphocytes and generated HBcAgspecific cytotoxic T lymphocytes.CONCLUSION:LV-Ub-HBcAg effectively induced DC maturation.The mature DCs efficiently induced T cell polarisation to Th1 and generated HBcAg-specific CTLs. | Jian-Hua Chen Yong-Sheng Yu Xiao-Hua Chen Hong-Hong Liu Guo-Qing Zang Zheng-Hao Tang | 2012 | World Journal of Gastroenterology2012，18，12： | 10 |

| 14 | Variability 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 | 2015 | Science China Earth Sciences2015，58，11： | 7 |
| 15 | Initial experience of single-incision plus one port left-side approach totally laparoscopic distal gastrectomy with uncut Roux-en-Y reconstruction显示文摘BACKGROUND Single incision plus one port left-side approach(SILS+1/L)totally laparoscopic distal gastrectomy(TLDG)is an emerging technique for the treatment of gastric cancer.Reduced port laparoscopic gastrectomy has a number of potential advantages for patients compared with conventional laparoscopic gastrectomy:relieving postoperative pain,shortening hospital stay and offering a better cosmetic outcome.Nevertheless,there are no previous reports on the use of SILS+1/L TLDG with uncut Roux-en-Y(uncut R-Y)reconstruction.AIM To investigate the initial feasibility of SILS+1/L TLDG with uncut Roux-en-Y digestive tract reconstruction(uncut R-Y reconstruction)to treat distal gastric cancer.METHODS A total of 21 patients who underwent SILS+1/L TLDG with uncut R-Y reconstruction for gastric cancer were enrolled.All patients were treated at The Second Hospital of Shandong University.Reconstructions were performed intracorporeally with 60 mm endoscopic linear stapler and 45 mm no-knife stapler.The clinicopathological characteristics,surgical details,postoperative short-term outcomes,postoperative follow-up upper gastrointestinal radiography findings and endoscopy results were analyzed retrospectively.RESULTS All SILS+1/L operations were performed by SILS+1/L TLDG successfully.The patient population included 13 men and 8 women with a mean age of 48.2 years(ranged from 40 years to 70 years)and median body mass index of 22.8 kg/m^2.There were no conversions to open laparotomy,and no other port was placed.The mean operation time was 146 min(ranged 130-180 min),and the estimated mean blood loss was 54 mL(ranged 20-110 mL).The mean duration to flatus and discharge was 2.3(ranged 1-3.5)and 7.3(ranged 6-9)d,respectively.The mean number of retrieved lymph nodes was 42(ranged 30-47).Two patients experienced mild postoperative complications,including surgical site infection(wound at the navel incision)and mild postoperative pancreatic fistula(grade A).Follow-up upper gastrointestinal radiography and endoscopy were carried out at 3 mo postoperatively.No patients experienced moderate or severe food stasis,alkaline gastritis or bile reflux during the follow-up period.No recanalization of the biliopancreatic limb was found.CONCLUSION SILS+1/L TLDG with uncut R-Y reconstruction could be safely performed as a reduced port surgery. | Wei Zhou Chang-Zheng Dong Yi-Feng Zang Ying Xue Xing-Guo Zhou Yu Wang Yin-Lu Ding | 2020 | World Journal of Gastroenterology2020，26，31： | 7 |
| 16 | A Stochastic Programming Strategy in Microgrid Cyber Physical Energy System for Energy Optimal Operation显示文摘This paper focuses on the energy optimal operation problem of microgrids(MGs) under stochastic environment.The deterministic method of MGs operation is often uneconomical because it fails to consider the high randomness of unconventional energy resources.Therefore,it is necessary to develop a novel operation approach combining the uncertainty in the physical world with modeling strategy in the cyber system.This paper proposes an energy scheduling optimization strategy based on stochastic programming model by considering the uncertainty in MGs.The goal is to minimize the expected operation cost of MGs.The uncertainties are modeled based on autoregressive moving average(ARMA) model to expose the effects of physical world on cyber world.Through the comparison of the simulation results with deterministic method,it is shown that the effectiveness and robustness of proposed stochastic energy scheduling optimization strategy for MGs are valid. | Hepeng Li Chuanzhi Zang Peng Zeng Haibin Yu Zhongwen Li | 2015 | IEEE/CAA Journal of Automatica Sinica2015，2，3： | 7 |

| 18 | Optimization of variables for maximizing efficacy and efficiency in aerial spray application to cotton using unmanned aerial systems显示文摘Aerial spraying can support efficient defoliation without crop contact.With the recent introduction to unmanned aerial system(UAS)for aerial spraying in China,there is a need to determine the optimum application variables to achieve high efficacy and efficiency with low costs.The present research involved field studies across two annual cotton production seasons in North Xinjiang,China.Four factors,including volume rate(A),tank mix including spray adjuvants(B),flight altitude(C),flight speed(D)and three levels of L9(3^(4))orthogonal arrays were carried out to optimize the application parameters for three types of UASs.These included different numbers of rotors as follows:four-rotors,six-rotors and eight-rotors.Spray coverage,distribution uniformity(coefficient of variation(CV)of droplet coverage),rates of cotton defoliation and boll opening,application efficiency and cost were measured and assessed.Results showed that:(1)the rates of defoliation and boll opening by aerial cotton defoliant application could meet the requirement of cotton mechanized harvesting;(2)the optimal scenario for the three UASs was A_(3)B_(2)C_(1)D_(3),Volume rate(A3):48 L/hm^(2);Tank mix and concentration(B_(2)):(Tuotulong 225+Sujie 750+Ethephon 2250)mL/hm^(2),Flight altitude(C_(1)):1.5 m,and Flight speeds(D_(3))for unmanned helicopters with four-rotors,six-rotors and eight-rotors were 3.12 m/s,2.51 m/s and 3.76 m/s,respectively.These results can provide guidance for cotton defoliant aerial spraying in China using UAS. | Juan Liao Ying Zang Xiwen Luo Zhiyan Zhou Yubin Lan Yu Zang Xiuyan Gu Weiming Xu Andrew John Hewitt | 2019 | International Journal of Agricultural and Biological Engineering2019，12，2： | 6 |
| 19 | Gram-scale synthesis of all-inorganic perovskite quantum dots with high Mn substitution ratio and enhanced dual-color emission显示文摘Mn-doped all-inorganic perovskite quantum dots (QDs) provide prominent applications in the fields of low-cost light source or display,because of their remarkable properties including dual-color emission and reduced lead content,as well as high photoluminescence quantum yields (PLQYs) and high stability.However,the existing synthesis approaches usually require hash conditions,such as high temperature and nitrogen protection,which is a major hurdler for the practical manufacturing.In addition,the significantly high Mn substitution ratio in CsPbX3 QDs is still challenging.The real dual-color emission with two strong emission peaks in the Mn-doped all-inorganic perovskite QDs has attracted great interest.Here we present a gram-scale approach to synthesize both CsPbxMn1-xCI3 and CsPb1-xMnxClyBr3-y QDs at 100 ℃ in the air with high Mn substitution ratio,up to 55.64% atomically.The as-prepared CsPb1-xMnxClyBr3-y QDs exhibit high PLQYs of 62.41% and dual-color emission with two strong emission peaks around at 400-450 nm and 600 nm,respectively.The enhanced peak at 400-450 nm is a result of the hybrid halides in CsPbBrxCl3-x host.Furthermore,the unique advantage of the optical emission and high PLQYs properties of the CsPbxMn1-xCl3 QDs has been demonstrated as invisible ink for encryption applications and polymer composites.Our gram-scale synthesis approach for Mn-doped all-inorganic perovskite QDs may boost the future research and practical applications of QDs-based white LED,spintronics,and molecular barcoding. | Lvming Dong Zhuo Chen Lei Ye Yan Yu Jianbing Zhang Huan Liu Jianfeng Zang | 2019 | Nano Research2019，12，7： | 6 |
