| 1 | Maize-soybean strip intercropping: Achieved a balance between high productivity and sustainability显示文摘Intercropping is one of the most vital practice to improve land utilization rate in China that has limited arable land resource. However, the traditional intercropping systems have many disadvantages including illogical field lay-out of crops, low economic value, and labor deficiency, which cannot balance the crop production and agricultural sustainability. In view of this, we developed a novel soybean strip intercropping model using maize as the partner, the regular maize-soybean strip intercropping mainly popularized in northern China and maize-soybean relay-strip intercropping principally extended in southwestern China. Compared to the traditional maize-soybean intercropping systems, the main innovation of field lay-out style in our present intercropping systems is that the distance of two adjacent maize rows are shrunk as a narrow strip, and a strip called wide strip between two adjacent narrow strips is expanded reserving for the growth of two or three rows of soybean plants. The distance between outer rows of maize and soybean strips are expanded enough for light use efficiency improvement and tractors working in the soybean strips. Importantly, optimal cultivar screening and increase of plant density achieved a high yield of both the two crops in the intercropping systems and increased land equivalent ratio as high as 2.2. Annually alternative rotation of the adjacent maize-and soybean-strips increased the grain yield of next seasonal maize, improved the absorption of nitrogen, phosphorus, and potasium of maize, while prevented the continuous cropping obstacles. Extra soybean production was obtained without affecting maize yield in our strip intercropping systems, which balanced the high crop production and agricultural sustainability. | DU Jun-bo HAN Tian-fu GAI Jun-yi YONG Tai-wen SUN Xin WANG Xiao-chun YANG Feng LIU Jiang SHU Kai LIU Wei-guo YANG Wen-yu | 2018 | Journal of Integrative Agriculture2018，17，4： | 34 |
| 2 | Kinetics of the leaching of TiO_2 from Ti-bearing blast furnace slag显示文摘Ti-bearing blast furnace slag is a valuable secondary resource containing about 24 percent of TiO2.In this paper a process of leaching Ti-bearing blast furnace slag with sulfuric acid to recover TiO2,and the kinetics of that reaction,are described.Under laboratory conditions the rate is controlled by a chemical reaction.The leaching reaction is in accord with a shrinking unre- acted-core model.The apparent reaction order of the leaching reaction was 1.222 and the apparent activation energy was 87.01 kJ/mol.The model fits the observed data well until 90%of the TiO2 has be leached from the particles.The model disagrees with observations during later periods of the reaction because the solution becomes supersaturated with Ti ions,which precipitate as H2TiO4.The assumptions of constant reactant concentration and that there is no effect from the product layer on diffusion,also cause the model to deviate from the actual values. | LIU Xiao-hua GAI Guo-sheng YANG Yu-fen SUI Zhi-tong LI Li FU Jian-xia | 2008 | Journal of China University of Mining and Technology2008，18，2： | 22 |

| 4 | Identification, Genetic Analysis and Mapping of Resistance to Phytophthora sojae of Pm28 in Soybean显示文摘Phytophthora sojae Kanfman and Gerdemann (P. sojae) is one of the most prevalent pathogens and causes Phytophthora root rot, which limits soybean production worldwide. Development of resistant cultivars is a cost-effective approach to controlling this disease. In this study, 127 soybean germplasm were evaluated for their responses to Phytophthora sojae strain Pm28 using the hypocotyl inoculation technique, and 49 were found resistant to the strain. The hypocotyl of P1, P2, F1, and F2:3 of two crosses of Ludou 4 (resistant)×Youchu 4 (susceptible) and Cangdou 5 (resistant)×Williams (susceptible) were inoculated with Pm28, and were used to analyze the inheritance of resistance. The population derived from the cross of Ludou 4×Youchu 4 was used to map the resistance gene (designated as Rps9) to a linkage group. 932 pairs of SSR primers were used to detect polymorphism, and seven SSR markers were mapped near the resistance gene. The results showed that the resistance to Pm28 in Ludou 4 and Cangdou 5 was controlled by a single dominant gene Rps9, which was located on the molecular linkage group N between the SSR markers Satt631 (7.5 cM) and Sat_186 (4.3 cM). | WU Xiao-ling ZHANG Bao-qiang SUN Shi ZHAO Jin-ming YANG Feng GUO Na GAI Jun-yi XING Han | 2011 | Agricultural Sciences in China2011，10，10： | 13 |

| 6 | S-1 plus gemcitabine chemotherapy followed by concurrent radiotherapy and maintenance therapy with S-1 for unresectable pancreatic cancer显示文摘AIM:To investigate the feasibility and efficacy of the combination of S-1 with gemcitabine followed by oral S-1 with concurrent radiotherapy(intensity modulated radiotherapy,IMRT) and maintenance therapy with S-1 for locally advanced pancreatic cancer.METHODS:Subjects selected in the study were patients who had unresectable and locally advanced pancreatic cancer without distant metastases,adequate organ and marrow functions,an Eastern Cooperative Oncology Group performance status of 0-1 and no prior anticancer therapy. Initially the subjects received two cycles of chemotherapy,oral administration of S-1 40 mg/m2 twice daily from day 1 to day 14 of a 21-d cycle,with 30-min intravenous infusions of gemcitabine 1000 mg/m2 on day 1 and day 8. Two weeks after the completion of chemotherapy,S-1 was administered orally with concurrent IMRT. Oral S-1 was administered at a dose of 80 mg/m2 per day twice daily from day 1 to day 14 and from day 22 to day 35. Radiation was concurrently delivered at a dose of 50.4 Gy(1.8 Gy/d,5 times per week,28 fractions). One month after the completion of chemotherapy and radiotherapy,S-1 was administered orally at a dose of 80 mg/m2 per day twice daily for 14 d,followed by a 14-d rest period. This cycle was repeated as maintenance therapy,until unacceptable toxicity occurred or the disease worsened. Thirty-two patients were involved in this study. The median followup was 15.6 mo(range:8.6-32.3 mo).RESULTS:Thirty-two patients completed the scheduled course of chemotherapy,while 30 patients(93.8%) received chemoradiotherapy with two patients ceasing to continue with radiotherapy. The major toxic effects were nausea and leukopenia. There was no grade 4 toxicity or treatment-related death. According to the Response Evaluation Criteria in Solid Tumors criteria,the objective tumor response was partial response in 17(53.1%) patients,stable disease in 9(28.1%),and progressive disease in 6(18.8%). The median overall survival and median progression-free survival were 15.2 mo and 9.3 mo,respectively. The survival rates at 1 year and 2 years were 75% and 34.4%,respectively.CONCLUSION:The combination of S-1 with gemcitabine followed by oral S-1 with IMRT and maintenance therapy with S-1 alone in patients with locally advanced pancreatic cancer may be considered a well-tolerated,promising treatment regimen. | Qing-Hua Ke Shi-Qiong Zhou Ji-Yuan Yang Wei Du Gai Liang Yong Lei Fei Luo | 2014 | World Journal of Gastroenterology2014，20，38： | 8 |
| 7 | Computed tomography angiography-guided percutaneous coronary intervention in chronic total occlusion显示文摘Objective:The aim of this study is to investigate if dual-source computed tomography(DSCT) could guide the percutaneous coronary intervention(PCI) of chronic total occlusion(CTO).Methods:We enrolled patients who were confirmed to have at least one native coronary artery CTO by DSCT before they underwent selective PCI in the period from December 2007 to October 2008.A CTO was defined as an obstruction of a native coronary artery with no luminal continuity.The CT-guided PCI procedure involved placing CT and fluoroscopic images side-by-side on the screen.DSCT images were analyzed for location,segment,plaque characteristics,calcification,and proximal lumen diameter of the CTO before PCI.The guidewire was advanced and manipulated under CT guidance.The PCI was carried out and the results were compared.Results:Seventy-four CTOs were assessed.PCI was successful in 57 cases of CTOs(77.0%).According to the results,CTOs were divided into two groups:successful-PCI and failed-PCI.All coronary artery paths of CTOs were clearly recognized by DSCT.In the successful-PCI group,soft plaques were detected much more often than those in the failed-PCI group,but fibrous and calcified plaques were seen more often in the failed-PCI group.Calcification severity in CTO segments showed a significant difference between the groups(P=0.014).Calcified plaques were detected in 20(35.1%) lesions in the successful-PCI group.More than 70% of the failures were calcified plaques,of which there were two arc-calcified and one circular-calcified lesions.Occlusions were longer in the failed-PCI group than those in the successful-PCI group [(38.8±25.0) vs.(18.0±15.3) mm,respectively,P<0.01].Fewer guidewires were used in the successful-PCI group compared with the failed-PCI group(1.7±1.0 vs.2.5±0.9,respectively,P<0.01).The logistic regression analysis indicated that predictors of recanalization of CTOs included occlusion length(P=0.0035,risk ratio(RR)=0.93) and calcification severity(P=0.05,RR=0.27).Multi-linear trends analysis showed that the factors affecting procedural time were CTO location(P=0.0141) and occlusion length(P=0.0035).Conclusions:DSCT could delineate the path of CTOs and characterize plaques.The outcomes of PCI were related to thrombolysis in myocardial infarction(TIMI) flow grade,CTO characteristics,severity of calcified plaques,and the length of occlusive segments.Occlusion length and calcification severity were independent predictors of CTOs.Occlusion length and CTO segments could also help to estimate the duration of interventional procedures. | Ping LI Lu-yue GAI Xia YANG Zhi-jun SUN Qin-hua JIN | 2010 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010，11，8： | 7 |
| 8 | Correlation of Gut Microbiome Between ASD Children and Mothers and Potential Biomarkers for Risk Assessment显示文摘Variation of maternal gut microbiota may increase the risk of autism spectrum disorders(ASDs) in offspring. Animal studies have indicated that maternal gut microbiota is related to neurodevelopmental abnormalities in mouse offspring, while it is unclear whether there is a correlation between gut microbiota of ASD children and their mothers. We examined the relationships between gut microbiome profiles of ASD children and those of their mothers, and evaluated the clinical discriminatory power of discovered bacterial biomarkers. Gut microbiome was profiled and evaluated by 16S ribosomal RNA gene sequencing in stool samples of 59 mother–child pairs of ASD children and 30 matched mother–child pairs of healthy children. Significant differences were observed in the gut microbiome composition between ASD and healthy children in our Chinese cohort. Several unique bacterial biomarkers, such as Alcaligenaceae and Acinetobacter, were identified. Mothers of ASD children had more Proteobacteria, Alphaproteobacteria, Moraxellaceae, and Acinetobacter than mothers of healthy children. There was a clear correlation between gut microbiome profiles of children and their mothers; however, children with ASD still had unique bacterial biomarkers, such as Alcaligenaceae, Enterobacteriaceae, and Clostridium. Candidate biomarkers discovered in this study had remarkable discriminatory power. The identified patterns of mother–child gut microbiome profiles may be important for assessing risks during the early stage and planning of personalized treatment and prevention of ASD via microbiota modulation. | Ning Li Junjie Yang Jiaming Zhang Cheng Liang Ying Wang Bin Chen Changying Zhao Jingwen Wang Guangye Zhang Dongmei Zhao Yi Liu Lehai Zhang Jun Yang Guimei Li Zhongtao Gai Lei Zhang Guoping Zhao | 2019 | Genomics, Proteomics & Bioinformatics2019，17，1： | 6 |
| 9 | Habitat use and diel activity pattern of the Tibetan Snowcock(Tetraogallus tibetanus):a case study using camera traps for surveying high-elevation bird species显示文摘Background:Global climate change has had significant effects on animal distribution and population dynamics in mid-latitude alpine areas,but we know little about the basic ecology of high-altitude species due to the difficulties of conducting field research in the harsh climate and habitat present at high elevations.The Tibetan Snowcock(Tetraogallus tibetanus) is a little-known phasianid distributing in alpine areas at extremely high elevations in the mountains surrounding the Tibetan Plateau.Estimating the species occupancy rate and discussing the factors affecting its distribution based on infrared-triggered camera techniques would provide both a baseline to measure the influence of global warming and valuable information on its conservation and ecology.Methods:We used infrared-triggered cameras to investigate the Tibetan Snowcock on the western slope of Mt.Gongga from June to November 2016.We used the R package 'overlap' to visualize its activity pattern,and used an occupancy model to both examine its habitat use as well as to determine the most influential variables affecting its habitat use.Results:Using 103 camera traps over 9213 camera-days,we recorded 428 instances of Tibetan Snowcock.The diel activity peaks of Tibetan Snowcock occurred during the periods of 8:00-10:00 am and 18:00-20:00 pm.The model estimate of occupancy for Tibetan Snowcock(0.830) was slightly higher than the na?ve site occupancy based on camera detections(0.663),indicating a wider use of habitat than the camera traps recorded.Elevation,slope,settlement density,road density,and EVI(enhanced vegetation index) were the most influential variables for its habitat use.Conclusions:The Tibetan Snowcock is confirmed to be diurnal.This species prefers an environment with a high elevation,gentle slope,and low EVI,apparently facing a trade-off between predator risk,foraging efficiency,and food availability.When human impact was low,there was a positive correlation between the habitat use of the Tibetan Snowcock and both its road and settlement densities.Infrared cameras and proper survey design are valuable for investigating extreme alpine phasianids. | Gai Luo Chuangming Yang Huaming Zhou Michael Seitz Yongjie Wu Jianghong Ran | 2019 | Avian Research2019，10，1： | 6 |

| 12 | Phase I study of chimeric anti-CD20 monoclonal antibody in Chinese patients with CD20-positive non-Hodgkin's lymphoma显示文摘Objective: This study was designed to determine the safety, pharmacokinetics and biologic effects of a humanmouse chimeric anti-CD20 monoclonal antibody(SCT400) in Chinese patients with CD20-positive B-cell nonHodgkin's lymphoma(CD20+ B-cell NHL). SCT400 has an identical amino acid sequence as rituximab, with the exception of one amino acid in the CH1 domain of the heavy chain, which is common in Asians.Methods: Fifteen patients with CD20+ B-cell NHL received dose-escalating SCT400 infusions(250 mg/m^2: n=3; 375 mg/m^2: n=9; 500 mg/m^2: n=3) once weekly for 4 consecutive weeks with a 24-week follow-up period. The data of all patients were collected for pharmacokinetics and pharmacodynamics analyses.Results: No dose-limiting toxicities were observed. Most drug-related adverse events were grade 1 or 2. Two patients had grade 3 or 4 neutropenia. Under premedication, the drug-related infusion reaction was mild. A rapid, profound and durable depletion of circulating B cells was observed in all dose groups without significant effects on T cell count, natural killer(NK) cell count or immunoglobulin levels. No patient developed antiSCT400 antibodies during the course of the study. SCT400 serum half-life(T1/2), maximum concentration(Cmax) and area under the curve(AUC) generally increased between the first and fourth infusions(P<0.05). At the 375 mg/m^2 dose, the T1/2 was 122.5±46.7 h vs. 197.0±75.0 h, respectively, and the Cmax was 200.6±20.2 μg/m L vs. 339.1±71.0 μg/m L, respectively. From 250 mg/m^2 to 500 mg/m^2, the Cmax and AUC increased significantly in a dose-dependent manner(P<0.05). Patients with a high tumor burden had markedly lower serum SCT400 concentrations compared with those without or with a low tumor burden. Of the 9 assessable patients, 1 achieved complete response and 2 achieved partial responses.Conclusions: SCT400 is well-tolerated and has encouraging preliminary efficacy in Chinese patients with CD20+ B-cell NHL. | Lin Gui Xiaohong Han Xiaohui He Yuanyuan Song Jiarui Yao Jianliang Yang Peng Liu Yan Qin Shuxiang Zhang Weijing Zhang Wenlin Gai Liangzhi Xie Yuankai Shi | 2016 | Chinese Journal of Cancer Research2016，28，2： | 5 |

| 14 | PIKA Provides an Adjuvant Effect to Induce Strong Mucosal and Systemic Humoral Immunity Against SARS-CoV显示文摘Severe Acute Respiratory Syndrome(SARS) is a deadly infectious disease caused by SARS Coronavirus(SARS-CoV).Inactivated SARS-CoV has been explored as a vaccine against SARS-CoV.However,safe and potent adjuvants,especially with more efficient and economical needle-free vaccination are always needed more urgently in a pandemic.The development of a safe and effective mucosal adjuvant and vaccine for prevention of emergent infectious diseases such as SARS will be an important advancement.PIKA,a stabilized derivative of Poly(I:C),was previously reported to be safe and potent as adjuvant in mouse models.In the present study,we demonstrated that the intraperitoneal and intranasal co-administration of inactivated SARS-CoV vaccine together with this improved Poly(I:C) derivative induced strong anti-SARS-CoV mucosal and systemic humoral immune responses with neutralizing activity against pseudotyped virus.Although intraperitoneal immunization of inactivated SARS-CoV vaccine alone could induce a certain level of neutralizing activity in serum as well as in mucosal sites,co-administration of inactivated SARS-CoV vaccine with PIKA as adjuvant could induce a much higher neutralizing activity.When intranasal immunization was used,PIKA was obligatorily for inducing neutralizing activity in serum as well as in mucosal sites and was correlated with both mucosal IgA and mucosal IgG response.Overall,PIKA could be a good mucosal adjuvant candidate for inactivated SARS-CoV vaccine for use in possible future pandemic. | Wei-wei Gai Yan Zhang Di-han Zhou Yao-qing Chen Jing-yi Yang Hui-min Yan | 2011 | Virologica Sinica2011，26，2： | 5 |
| 15 | Exploration of presence/absence variation and corresponding polymorphic markers in soybean genome显示文摘This study was designed to reveal the genome‐wide distribution of presence/absence variation(PAV) and to establish a database of polymorphic PAV markers in soybean. The 33 soybean whole‐genome sequences were compared to each other with that of Williams 82 as a reference genome. A total of 33,127 PAVs were detected and 28,912 PAV markers with their primer sequences were designed as the database NJAUSoyPAV_1.0. The PAVs scattered on whole genome while only 518(1.8%) overlapped with simple sequence repeats(SSRs) in BARCSOYSSR_1.0database. In a random sample of 800 PAVs, 713(89.13%) showed polymorphism among the 12 differential genotypes. Using 126 PAVs and 108 SSRs to test a Chinese soybean germplasm collection composed of 828 Glycine soja Sieb. et Zucc. and Glycine max(L.) Merr. accessions, the per locus allele number and its variation appeared less in PAVs than in SSRs. The distinctness among alleles/bands of PCR(polymerase chain reaction) products showed better in PAVs than in SSRs, potential in accurate marker‐assisted allele selection. The association mapping results showed SSR t PAV was more powerful than any single marker systems.The NJAUSoyPAV_1.0 database has enriched the source of PCR markers, and may fit the materials with a range of per locus allele numbers, if jointly used with SSR markers. | Yufeng Wang Jiangjie Lu Shouyi Chen Liping Shu Reid G.Palmer Guangnan Xing Yan Li Shouping Yang Deyue Yu Tuanjie Zhao Junyi Gai | 2014 | Journal of Integrative Plant Biology2014，56，10： | 5 |

| 18 | Quality of terrestrial data derived from UAV photogrammetry:A case study of Hetao irrigation district in northern China显示文摘Most crops in northern China are irrigated,but the topography affects the water use,soil erosion,runoff and yields.Technologies for collecting high-resolution topographic data are essential for adequately assessing these effects.Ground surveys and techniques of light detection and ranging have good accuracy,but data acquisition can be time-consuming and expensive for large catchments.Recent rapid technological development has provided new,flexible,high-resolution methods for collecting topographic data,such as photogrammetry using unmanned aerial vehicles(UAVs).The accuracy of UAV photogrammetry for generating high-resolution Digital Elevation Model(DEM)and for determining the width of irrigation channels,however,has not been assessed.A fixed-wing UAV was used for collecting high-resolution(0.15 m)topographic data for the Hetao irrigation district,the third largest irrigation district in China.112 ground checkpoints(GCPs)were surveyed by using a real-time kinematic global positioning system to evaluate the accuracy of the DEMs and channel widths.A comparison of manually measured channel widths with the widths derived from the DEMs indicated that the DEM-derived widths had vertical and horizontal root mean square errors of 13.0 and 7.9 cm,respectively.UAV photogrammetric data can thus be used for land surveying,digital mapping,calculating channel capacity,monitoring crops,and predicting yields,with the advantages of economy,speed and ease. | Hongming Zhang Jiangtao Yang Jantiene E.M.Baartman Shuqin Li Bei Jin Wenting Han Xiaomei Yang Lingtong Gai Coen J.Ritsema Violette Geissen | 2018 | International Journal of Agricultural and Biological Engineering2018，11，3： | 4 |
| 19 | Cloning and Characterization of a Novel Gene GmMF1 in Soybean (Glycine max L. Merr.)显示文摘Cytoplasmic male sterility plays an important role in utilization of crop heterosis. Screening of soybean for novel genes related to male sterility in soybean could provide a basis for studying the molecular mechanism of male sterility in plants. In this study, gene differential expressions between the cytoplasmic male-sterile line NJCMS1A and its maintainer line NJCMS1B in soybean were analyzed using cDNA-AFLP. A differentially expressed fragment, GmMF-T4A15, was isolated from large flower buds of NJCMS1B. By searching the soybean genomic library and PCR amplification, the cDNA full-length sequence of 1 311 bp was obtained and named GmMF1. The expression characteristics of GmMF1 were studied by semiquantitative real-time PCR and real-time quantitative PCR. The results showed that GmMF1 was expressed highly in flower buds of NJCMS1B. The deduced protein contains 436 amino acids and shows high similarity to members of the DUF620 protein family with unknown functions in other plant species. It is predicted that the protein encoded by GmMF1 is localized in the nucleus. | JIANG Wei YANG Shou-ping YU De-yue GAI Jun-yi | 2011 | Agricultural Sciences in China2011，10，12： | 4 |
| 20 | Effects of the crude extract of Polygala tenuifolia Willd on human sperm in vitro显示文摘The aim of the present study is to analyze sperm membrane changes and the spermicidal effect in treatment with the crude extract from Polygala tenuifolia Willd (PTW) in vitro.The root of PTW was extracted in distilled water.Normal human spermatozoa were used to assess the spermicidal activity (Sander-Cramer assay) of the extract from the PTW root.The hypo-osmotic swelling (HOS) test and the eosin Y (EY) staining were used to detect the integrity of sperm membrane and vitality.The sperm chromatin dispersion (SCD) test was performed to determine sperm DNA integrity.N-9 was used as a reference standard and semen added to physiological saline was used as the control.Semen samples were donated by 42 healthy fertile men.The crude extract from the root of PTW could immobilize and kill 100% spermatozoa within 20 s in vitro at the concentrations of 20.0 and 10.0 mg/ml;at the concentration of 5.0 mg/ml,spermatozoa were immobilized in (39.5±3.2) s.In the groups of the crude extract from the root of PTW and N-9 solution,the rate of the normal HOS (tails swollen) and the white head (unstained) was 0%,and the rate of the abnormal HOS (tails unswollen) and red head (stained) was 100%.Sperm DNA fragmentation showed no change in exposure to the crude extract from the root of PTW and N-9 solution.The sperm revival test did not show any spermatozoa that recovered their motilities.The rapid spermicidal activity of the crude extract from the root of PTW in vitro may occur by the disruption of the sperm membrane integrity. | Yi QIU Lei-guang WANG Yi-fang JIA Dan-tong YANG Mei-hua ZHANG Yan-ping ZHANG Li-hong ZHANG Ling GAI | 2011 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2011，12，6： | 4 |
