| 1 | Application of deep learning in ecological resource research:Theories, methods, and challenges显示文摘Ecological resources are an important material foundation for the survival,development,and self-realization of human beings.In-depth and comprehensive research and understanding of ecological resources are beneficial for the sustainable development of human society.Advances in observation technology have improved the ability to acquire long-term,cross-scale,massive,heterogeneous,and multi-source data.Ecological resource research is entering a new era driven by big data.Traditional statistical learning and machine learning algorithms have problems with saturation in dealing with big data.Deep learning is a method for automatically extracting complex high-dimensional nonlinear features,which is increasingly used for scientific and industrial data processing because of its ability to avoid saturation with big data.To promote the application of deep learning in the field of ecological resource research,here,we first introduce the relationship between deep learning theory and research on ecological resources,common tools,and datasets.Second,applications of deep learning in classification and recognition,detection and localization,semantic segmentation,instance segmentation,and graph neural network in typical spatial discrete data are presented through three cases:species classification,crop breeding,and vegetation mapping.Finally,challenges and opportunities for the application of deep learning in ecological resource research in the era of big data are summarized by considering the characteristics of ecological resource data and the development status of deep learning.It is anticipated that the cooperation and training of cross-disciplinary talents may promote the standardization and sharing of ecological resource data,improve the universality and interpretability of algorithms,and enrich applications with the development of hardware. | Qinghua GUO Shichao JIN Min LI Qiuli YANG Kexin XU Yuanzhen JU Jing ZHANG Jing XUAN Jin LIU Yanjun SU Qiang XU Yu LIU | 2020 | Science China Earth Sciences2020，63，10： | 7 |
| 2 | The chimeric genes in the hybrid lineage of Carassius auratus cuvieri(♀)×Carassius auratus red var.(♂)显示文摘Hybridization can combine the genomes of different strains or species, which leads to changes of genotype and phenotype in the hybrids. In this study, we aimed to investigate the genetic variations of hybrids(WR-F1 and WR-F2) derived from the intraspecific hybridization of white crucian carp(Carassius auratus cuvieri, WCC, ♀) and red crucian carp(Carassius auratus red var., RCC, ♂). Here, we compared the orthologous genes in the liver transcriptomes of hybrids with those of WCC and RCC, and classified the orthologous genes into eight gene patterns within three categories(chimera, mutant, and biparental origin genes).The results revealed 19.04%, 4.17% chimeric genes and 6.90%, 5.05% mutations of orthologous genes in WR-F1 and WR-F2 respectively. Seventeen of twenty-three characterized genes(77%) were confirmed to be the chimeras at the genomic DNA level.The GO classification discovered that some chimeric and mutant genes were related to metabolic process, immune system and developmental process in WR-F1. Our results provide the new evidence that hybridization can combine the parental genomes,leading to changes in the genotype of the resultant hybrids. This is the first report on the formation of chimeric genes from fish intraspecific hybridization, which is potentially interesting from the context of both evolution and the genetic breeding of fish. | Qingfeng Liu Yanhua Qi Qiuli Liang Xiujuan Xu Fangzhou Hu Jing Wang Jun Xiao Shi Wang Wuhui Li Min Tao Qinbo Qin Rurong Zhao Zhanzhou Yao Shaojun Liu | 2018 | Science China(Life Sciences)2018，61，9： | 6 |

| 4 | SIMS U-Pb dating of rutile within eclogitic xenoliths in the Early Cretaceous adakitic rocks of the Xuzhou-Huaibei area, China: Constraints on the timing of crustal thickening of the eastern North China Craton显示文摘This paper reports the results of secondary ion mass spectrometry(SIMS) U-Pb dating of rutile within eclogitic xenoliths from the Early Cretaceous adakitic rocks in the Xuzhou-Huaibei area of China and discusses the geological significance of these new dates. The dating of rutile from pargasite-bearing eclogite and garnet clinopyroxenite(retrograde eclogite) yielded ages of 209 ± 25 and 132 ± 7 Ma, respectively. The former is consistent with the timing of the first stage of exhumation of the Dabie-Sulu orogenic belt and provides evidence of crustal thickening within the southeastern margin of the North China Craton during the early Mesozoic, related to subduction and collision between the Yangtze and North China cratons. The latter age is similar to the timing of emplacement of the hosting intrusion and indicates that the rutile U-Pb system was triggered after uplifting by the intrusion of the hosting magmas. It implies that garnet clinopyroxenite was previously at the depth where the temperature was above the rutile U-Pb closure temperature. | XIONG BoQin XU WenLiang LI QiuLi YANG DeBin ZHOU QunJun | 2015 | Science China Earth Sciences2015，58，7： | 4 |
| 5 | Approaching Malaria Elimination in China显示文摘Malaria has been one of the most important public health problems over China and world.When dated back to the mid-20th century,malaria seriously affected the health of Chinese people with widespread epidemics.About 30 million malaria cases with an estimated 1%mortality rate were recorded in China each year in the 1940s,which caused an extremely high disease burden and a toll on the labor force(1–2).Even as recently as the 1970s,a peak in the incidence of malaria was recorded with 24.1 million cases(1–2). | Ning Xiao Qiuli Xu Jun Feng Zhigui Xia Lei Duan Duoquan Wang Yayi Guan Xiao-nong Zhou | 2020 | China CDC weekly2020，2，17： | 2 |

| 12 | Effect of TrκB-PLC/IP3 pathway on intestinal inflammatory factors and enterocyte apoptosis in mice with colitis显示文摘In this study,we aimed to explore the effect of TrκB-PLC/IP3 pathway on intestinal inflammatory factors and enterocyte apoptosis in mice with colitis.The mouse model of ulcerative colitis was established by medication,and 40 SPF C57BL/6J mice(8 weeks old)were randomly divided into normal group(healthy mice,n=10),control group(sham-operated mice,n=10),model group(model mice without any treatment,n=10),and K252a group(model mice treated with 100 pmol/kg TrκB-PLC/IP3 pathway inhibitor for 5 days before clysis,n=10).The results showed that mice in the model and K252a groups,as compared with normal and control groups,had no significant ch a nges in the levels and protein expressi ons of serum tumor necrosis factor-α(TNF-α)and TNF-γin the colo n tissues(P>0.05),and had a significant in crease in disease activity index,colon mucosa damage index,tissue damage index scores,and levels and protein expressions of serum interleukin-4(IL-4)and IL8,but had a significant decrease in the level and protein expression of serum lb10(P<0.05).Mice in the model and K252a groups showed blocked enterocyte cycle progression,elevated apoptosis ratio,and significantly in creased mRNA and protein expressi ons of Caspase3,Bax,FasL,and Fas,but significantly reduced mRNA and protein expressions of p-TrκB,PLC-γ1,IP3,and Bcl-2(P<0.05).Moreover,intestinal inflammation and apoptosis induced by colitis in the K252a group became more aggravated by inhibiting the activity of TrκB-PLC/IP3 pathway.In conclusi on,inhibiti on of TrκB-PLC/IP3 pathway can in crease the expressi on of in testinal inflammatory factors and promote enterocyte apoptosis in mice with colitis. | Guangmeng Xu Yajuan Sun Huaiqiang He Qiuli Xue Yajie Liu Lihua Dong | 2020 | Acta Biochimica et Biophysica Sinica2020，52，6： | 0 |
| 13 | Role of international network on surveillance and response system leading to malaria elimination: China’s engagement in global health显示文摘China has accumulated multiple practices and experiences in building and enhancing malaria surveillance and response system. As China’s engagement into global health has gathered stronger momentum than ever, China together with the Swiss Tropical and Public Health Institute and WHO has organised five sessions of the International Forum on Surveillance-Response System Leading to Tropical Diseases Elimination during 2012–2020, in which malaria elimination has always been one of the hottest topics. In this study, the roles of international network on the surveillance and response system were explored to achieve a global malaria-free goal. China’s approach to malaria elimination has demonstrated significance of global collaboration on taking joint prevention and control, and building a worldwide institutional-based network. | Shenning Lu Lulu Huang Lei Duan Qiuli Xu Xuejiao Ma Wei Ding Duoquan Wang Shan Lv Ning Xiao | 2022 | Infectious Diseases of Poverty2022，11，3： | 0 |
| 14 | Canopy structure:An intermediate factor regulating grassland diversity-function relationships under human disturbances显示文摘Grasslands are one of the largest coupled human-nature terrestrial ecosystems on Earth,and severe anthropogenic-induced grassland ecosystem function declines have been reported recently.Understanding factors influencing grassland ecosystem functions is critical for making sustainable management policies.Canopy structure is an important factor influencing plant growth through mediating within-canopy microclimate(e.g.,light,water,and wind),and it is found coordinating tightly with plant species diversity to influence forest ecosystem functions.However,the role of canopy structure in regulating grassland ecosystem functions along with plant species diversity has been rarely investigated.Here,we investigated this problem by collecting field data from 170 field plots distributed along an over 2000 km transect across the northern agro-pastoral ecotone of China.Aboveground net primary productivity(ANPP)and resilience,two indicators of grassland ecosystem functions,were measured from field data and satellite remote sensing data.Terrestrial laser scanning data were collected to measure canopy structure(represented by mean height and canopy cover).Our results showed that plant species diversity was positively correlated to canopy structural traits,and negatively correlated to human activity intensity.Canopy structure was a significant indicator for ANPP and resilience,but their correlations were inconsistent under different human activity intensity levels.Compared to plant species diversity,canopy structural traits were better indicators for grassland ecosystem functions,especially for ANPP.Through structure equation modeling analyses,we found that plant species diversity did not have a direct influence on ANPP under human disturbances.Instead,it had a strong indirect effect on ANPP by altering canopy structural traits.As to resilience,plant species diversity had both a direct positive contribution and an indirect contribution through mediating canopy cover.This study highlights that canopy structure is an important intermediate factor regulating grassland diversity-function relationships under human disturbances,which should be included in future grassland monitoring and management. | Xiaoxia Zhao Yuhao Feng Kexin Xu Mengqi Cao Shuya Hu Qiuli Yang Xiaoqiang Liu Qin Ma Tianyu Hu Maggi Kelly Qinghua Guo Yanjun Su | 2023 | Fundamental Research2023，3，2： | 0 |
| 15 | Comparison of Anti-inflammatory and Analgesic Effects of Fresh and Dry Products of Zhuang Medicine Asystaia gangetica显示文摘[Objectives]To compare anti-inflammatory and analgesic effects of fresh and dry products of Zhuang medicine Asystaia gangetica on mice.[Methods]Experiments were performed using glacial acetic acid to increase capillary permeability in mice,cotton ball to cause granulomatous formation in mice,xylene to cause auricular swelling in mice,chronic inflammation,and acetic acid-induced pain and hot-plate pain.Besides,the anti-inflammatory and analgesic effects of fresh and dry products of A.gangetica on mice were observed with the indicators of capillary permeability in the abdominal cavity,swelling rate of auricles,cotton ball granulomas and writhing times,and thermal pain threshold.[Results]Fresh products of A.gangetica had significant inhibitory effects on peritoneal capillary permeability increase in mice induced by glacial acetic acid,mouse auricle swelling induced by xylene,and mouse granuloma formation induced by cotton balls.Dry products of A.gangetica also significantly inhibited the auricle swelling in mice induced by xylene,but the effect intensity was weaker than that of fresh products.In addition,dry products of A.gangetica showed a certain tendency to inhibit the increase of capillary permeability in the abdominal cavity of mice induced by glacial acetic acid.In the analgesic experiment,both fresh and dry products of A.gangetica showed better analgesic effect,but caused pain on the hot plate,and the analgesic effect time of fresh products was shorter than that of dry products.[Conclusions]Both fresh and dry products of Zhuang medicine A.gangetica have certain anti-inflammatory and analgesic effects. | Ke YANG Xianxing LIANG Ning XU Qiuli LONG Fang CHEN Chunhui ZENG | 2020 | Medicinal Plant2020，11，3： | 0 |
