| 1 | Cytological, physiological, and transcriptomic analyses of golden leaf coloration in Ginkgo biloba L显示文摘Ginkgo biloba is grown worldwide as an ornamental plant for its golden leaf color.However,the regulatory mechanism of leaf coloration in G.biloba remains unclear.Here,we compared G.biloba gold-colored mutant leaves and normal green leaves in cytological,physiological and transcriptomic terms.We found that chloroplasts of the mutant were fewer and smaller,and exhibited ruptured thylakoid membranes,indistinct stromal lamellae and irregularly arranged vesicles.Physiological experiments also showed that the mutant had a lower chlorophyll,lower flavonoid and higher carotenoid contents(especially lutein).We further used transcriptomic sequencing to identify 116 differentially expressed genes(DEGs)and 46 transcription factors(TFs)involved in chloroplast development,chlorophyll metabolism,pigment biosynthesis and photosynthesis.Among these,the chlorophyll biosynthesis-related PPO showed down-regulation,while chlorophyll degradation-related NYC/NOL had up-regulated expression in mutant leaves.Z-ISO,ZDS,and LCYE,which are involved in carotenoid biosynthesis were up-regulated.Quantitative real-time PCR(RT-qPCR)further confirmed the altered expression levels of these genes at three stages.The alteration of PPO and NYC/NOL gene expression might affect chlorophyll biosynthesis and promote degradation of chlorophyll b to chlorophyll a,while the up-regulated genes Z-ISO,ZDS and LCYE enhanced carotenoid accumulation.Consequently,changes in the ratio of carotenoids to chlorophylls were the main factors driving the golden leaf coloration in the mutant G.biloba. | Wei-xing Li Shun-bo Yang Zhaogeng Lu Zhi-chong He Yun-ling Ye Bei-bei Zhao Li Wang Biao Jin | 2018 | Horticulture Research2018，5，1： | 28 |
| 2 | Forest Ecosystem Services and Their Values in Beijing显示文摘As the most important ecosystem in Beijing, the forest supports a lot of ecosystem services to local and around communities, which plays a key role in the maintenance of urban ecological security.However, the valuation on the forest ecosystem services based on regional scale could not provide precise and reasonable values for forestry sector management.In this study, we estimated the magnitudes and economic values of the forest ecosystem services in Beijing at sublot level.The economic value of forest ecosystem services in Beijing was estimated to be 19 339.71×10 6 yuan(RMB) in 2004.Among all the ecosystem services indicators we estimated in this study, only fruit, timber and part of the recreation(which only include the tourism income from the forest parks and scenic areas, but not include that from other forest types) were measured in the social economic system.As estimated in this study, more than 82.19% of the economic value of forest ecosystem services could not be measured in the socio-economic statistical system.The importance of forest ecosystem services in Beijing to human welfare was underestimated by the socio-economic system.Therefore, the policies about the eco-compensation of forest ecosystem services should be established to maintain the sustainable supply of the forest ecosystem services in Beijing. | XIE Gaodi LI Wenhua XIAO Yu ZHANG Biao LU Chunxia AN Kai WANG Jixing XU Kang WANG Jinzeng | 2010 | Chinese Geographical Science2010，20，1： | 18 |

| 9 | Efficacy and safety of the long-acting fusion inhibitor albuvirtide in antiretroviral-experienced adults with human immunodeficiency virus-1:interim analysis of the randomized,controlled,phase 3,non-inferiority TALENT study显示文摘Background:Albuvirtide is a once-weekly injectable human immunodeficiency virus(HIV)-1 fusion inhibitor.We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs.Methods:We carried out a 48-week,randomized,controlled,open-label non-inferiority trial at 12 sites in China.Adults on the World Health Organization(WHO)-recommended first-line treatment for>6 months with a plasma viral load>1000 copies/mL were enrolled and randomly assigned(1:1)to receive albuvirtide(once weekly)plus ritonavir-boosted lopinavir(ABT group)or the WHO-recommended second-line treatment(NRTI group).The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks.Non-inferiority was prespecified with a margin of 12%.Results:At the time of analysis,week 24 data were available for 83 and 92 patients,and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups,respectively.At 48 weeks,80.4%of patients in the ABT group and 66.0%of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL,meeting the criteria for non-inferiority.For the per-protocol population,the superiority of albuvirtide over NRTI was demonstrated.The frequency of grade 3 to 4 adverse events was similar in the two groups;the most common adverse events were diarrhea,upper respiratory tract infections,and grade 3 to 4 increases in triglyceride concentration.Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group.Conclusions:The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug.This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.Trial registration:ClinicalTrials.gov Identifier:NCT02369965;http://gffzz90ed6ce9d87f4798swvwn6xkuvpq96woc.ffgz.tsg.suse.edu.cn Clinical Trial Registry No.ChiCTR-TRC-14004276;http://gffzz62a03ee25e6f4a77hwvwn6xkuvpq96woc.ffgz.tsg.suse.edu.cn/enindex.aspx. | Bin Su Cheng Yao Qing-Xia Zhao Wei-Ping Cai Min Wang Hong-Zhou Lu Yuan-Yuan Chen Li Liu Hui Wang Yun He Yu-Huang Zheng Ling-Hua Li Jin-Feng Chen Jian-Hua Yu Biao Zhu Min Zhao Yong-Tao Sun Wen-Hui Lun Wei Xia Li-Jun Sun Li-Li Dai Tai-Yi Jiang Mei-Xia Wang Qing-Shan Zheng Hai-Yan Peng Yao Wang Rong-Jian Lu Jian-Hua Hu Hui Xing Yi-Ming Shao Dong Xie Tong Zhang Fu-Jie Zhang Hao Wu TALENT Study Team | 2020 | Chinese Medical Journal2020，，24： | 10 |
| 10 | Comparison of efficacy and safety of transpancreatic septotomy, needle-knife fistulotomy or both based on biliary cannulation unintentional pancreatic access and papillary morphology显示文摘Background: Precut sphincterotomy has been widely performed to facilitate selective biliary access when standard cannulation attempts failed during endoscopic retrograde cholangiopancreatography(ERCP). However, scarce data are available on different precut techniques for difficult biliary cannulation. This study aimed to evaluate the efficacy and safety of transpancreatic septotomy(TPS), needle-knife fistulotomy(NKF) or both based on the presence of unintentional pancreatic access and papillary morphology. Methods: Between March 2008 and December 2016, 157 consecutive patients undergoing precutting for an inaccessible bile duct during ERCP were identified. Precut techniques were chosen depending on repetitive inadvertent pancreatic cannulation and the papillary morphology. We retrospectively assessed the rates of cannulation success and procedure-related complications among three groups, namely TPS, NKF, and TPS followed by NKF. Results: The baseline characteristics of the three groups were comparable. The overall success rate of biliary cannulation reached 98.1%, including 111 of 113(98.2%) with TPS, 35 of 36(97.2%) with NKF and 8 of 8(100%) with NKF following TPS, without significant difference among groups. The incidences of total complications and post-ERCP pancreatitis were 9.6% and 7.6%, respectively. There was a trend towards less frequent post-ERCP pancreatitis after NKF(0%) compared with 11 cases(9.7%) after TPS and one case(12.5%) after NKF following TPS, but not significantly different( P = 0.07). No severe adverse event occurred during this study period. Conclusions: The choice of precut techniques by the presence of unintended pancreatic access and the papillary morphology brought about a high success rate without increasing risk in difficult biliary cannulation. | Jun Wen Tao Li Yi Lu Li-Ke Bie Biao Gong | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，1： | 9 |

| 12 | Salivary mycobiome dysbiosis and its potential impact on bacteriome shifts and host immunity in oral lichen planus显示文摘The biodiversity of the mycobiome,an important component of the oral microbial community,and the roles of fungal–bacterial and fungal–immune system interactions in the pathogenesis of oral lichen planus (OLP) remain largely uncharacterized.In this study,we sequenced the salivary mycobiome and bacteriome associated with OLP.First,we described the dysbiosis of the microbiome in OLP patients,which exhibits lower levels of fungi and higher levels of bacteria.Significantly higher abundances of the fungi Candida and Aspergillus in patients with reticular OLP and of Alternaria and Sclerotiniaceae_unidentified in patients with erosive OLP were observed compared to the healthy controls.Aspergillus was identified as an “OLP-associated” fungus because of its detection at a higher frequency than in the healthy controls.Second,the co-occurrence patterns of the salivary mycobiome–bacteriome demonstrated negative associations between specific fungal and bacterial taxa identified in the healthy controls,which diminished in the reticular OLP group and even became positive in the erosive OLP group.Moreover,the oral cavities of OLP patients were colonized by dysbiotic oral flora with lower ecological network complexity and decreased fungal–Firmicutes and increased fungal–Bacteroidetes sub-networks.Third,several keystone fungal genera (Bovista,Erysiphe,Psathyrella,etc.) demonstrated significant correlations with clinical scores and IL-17 levels.Thus,we established that fungal dysbiosis is associated with the aggravation of OLP.Fungal dysbiosis could alter the salivary bacteriome or may reflect a direct effect of host immunity,which participates in OLP pathogenesis. | Yan Li Kun Wang Bo Zhang Qichao Tu Yufei Yao Bomiao Cui Biao Ren Jinzhi He Xin Shen Joy D.Van Nostrand Jizhong Zhou Wenyuan Shi Liying Xiao Changqing Lu Xuedong Zhou | 2019 | International Journal of Oral Science2019，11，3： | 8 |
| 13 | Visible calculation of mining index based on stope 3D surveying and block modeling显示文摘Aimed at the CMS laser scanning theory and characteristic, a combined actual situation of stope N4-5 of Fankou Lead-Zinc Mine and complementary monitoring of the stope were carried out by carefully choos- ing two measuring points. The cavity 3D visible model was created by large-scale mining industry soft- ware Surpac after changing the measured data. The stope mine design model, bottom structural model and backfill model of the south and north sides of the stope N4-5 were established according to the stope design data. On this basis, the stope block model was established, and then block attribute was estimated. The amount the ore remains, mullock, backfill and total mined ore were calculated through the solid model restrains. Finally, the stope mining dilution rate and loss rate reached 8.2% and 1.47%, respectively. The practice indicates that the mining index visible calculation method based on cavity 3D monitoring and stope block modeling can make up the deficiency of adopting the solid model to directly carry out the Boolean operation. The stope mining indexes obtained by this method are accurate and reliable, and can be used to guide the actual production management and estimate the mining quality. | Liu Xiaoming Luo Zhouquan Yang Biao Lu Guang Cao Shengxiang Jiang Xinjian | 2012 | International Journal of Mining Science and Technology2012，22，2： | 7 |

| 15 | Detection and characterization of diverse alpha-and betacoronaviruses from bats in China显示文摘Bats have been implicated as important reservoir hosts of alpha- and betacoronaviruses. In this study, diverse coronaviruses(CoVs) were detected in 50 of 951(positive rate 5.3%) intestinal specimens of eight bat species collected in four provinces and the Tibet Autonomous Region of China by pan-coronavirus RT-PCR screening. Based on 400-nt RNA-dependent RNA polymerase(Rd RP) sequence analysis, eight belonged to genus Alphacoronavirus and 42 to Betacoronavirus.Among the 50 positive specimens, thirteen gave rise to CoV full-length Rd RP gene amplification for further sequence comparison, of which three divergent sequences(two from a unreported province) were subjected to full genome sequencing. Two complete genomes of betacoronaviruses(JTMC15 and JPDB144) and one nearly-complete genome of alphacoronavirus(JTAC2) were sequenced and their genomic organization predicted. The present study has identified additional numbers of genetically diverse bat-borne coronaviruses with a wide distribution in China. Two new species of bat CoV, identified through sequence comparison and phylogenetic analysis, are proposed. | Lin Xu Fuqiang Zhang Weihong Yang Tinglei Jiang Guanjun Lu Biao He Xingyu Li Tingsong Hu Gang Chen Yun Feng Yuzhen Zhang Quanshui Fan Jiang Feng Hailin Zhang Changchun Tu | 2016 | Virologica Sinica2016，31，1： | 6 |

| 17 | Long-term outcomes of endoscopic papillary balloon dilation for removal of bile duct stones in Billroth Ⅱ gastrectomy patients显示文摘Background: Endoscopic papillary balloon dilation(EPBD) for common bile duct(CBD) stones removal in Billroth Ⅱ gastrectomy patients is feasible. However, the long-term outcomes of this technique are not clear. The aim of this study was to evaluate the procedural and long-term outcomes of EPBD for removal of CBD stones in Billroth Ⅱ gastrectomy patients.Methods: The records of patients with previous Billroth Ⅱ gastrectomy referred for CBD stones removal with endoscopic retrograde cholangiopancreatography(ERCP) between July 1, 2008 and September 1,2016 were retrospectively reviewed. The main outcomes of stone clearance, ERCP-related adverse events,and stone recurrence were analyzed.Results: A total of 83 patients with previous Billroth Ⅱ gastrectomy underwent ERCP in our center were reviewed. Forty-nine consecutive patients with previous Billroth Ⅱ gastrectomy referred to EPBD for removal of CBD stones underwent 59 ERCP procedures were enrolled in the end. The overall successful CBD stones clearance was achieved in 42 patients(85.7%). ERCP-related adverse events was in 3 ERCP procedures(5.1%). Severe complications, including perforation and bleeding, were not observed. Six of 49 patients(12.2%) had stone recurrence after a median period of22.5 months(range 6–71 months) from the end of stone removal treatment. Female [odds ratio(OR) = 11.352; 95% confidence interval(95% CI): 1.040–123.912; P = 0.046] and previous mechanical lithotripsy(OR = 13.423; 95% CI: 1.070–168.434; P = 0.044) were significantly associated with stone recurrence.Conclusions: At long-term follow-up, EPBD for removal of CBD stones appeared to be safe and effective in Billroth Ⅱ gastrectomy patients. Female and previous mechanical lithotripsy may be risk factors for stone recurrence. | Tao Li Jun Wen Li-Ke Bie Yi Lu Biao Gong | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，3： | 6 |
| 18 | The genome of Medicago polymorpha provides insights into its edibility and nutritional value as a vegetable and forage legume显示文摘Medicago polymorpha is a nutritious and palatable forage and vegetable plant that also fixes nitrogen.Here,we reveal the chromosome-scale genome sequence of M.polymorpha using an integrated approach including Illumina,PacBio and Hi-C technologies.We combined PacBio full-length RNA-seq,metabolomic analysis,structural anatomy analysis and related physiological indexes to elucidate the important agronomic traits of M.polymorpha for forage and vegetable usage.The assembled M.polymorpha genome consisted of 457.53Mb with a long scaffold N50 of 57.72Mb,and 92.92%(441.83Mb)of the assembly was assigned to seven pseudochromosomes.Comparative genomic analysis revealed that expansion and contraction of the photosynthesis and lignin biosynthetic gene families,respectively,led to enhancement of nutritious compounds and reduced lignin biosynthesis in M.polymorpha.In addition,we found that several positively selected nitrogen metabolism-related genes were responsible for crude protein biosynthesis.Notably,the metabolomic results revealed that a large number of flavonoids,vitamins,alkaloids,and terpenoids were enriched in M.polymorpha.These results imply that the decreased lignin content but relatively high nutrient content of M.polymorpha enhance its edibility and nutritional value as a forage and vegetable.Our genomic data provide a genetic basis that will accelerate functional genomic and breeding research on M.polymorpha as well as other Medicago and legume plants. | Jiawen Cui Zhaogeng Lu Tianyi Wang Gang Chen Salma Mostafa Hailong Ren Sian Liu Chunxiang Fu Li Wang Yingfang Zhu Jinkai Lu Xiang Chen Zhenwu Wei Biao Jin | 2021 | Horticulture Research2021，8，1： | 6 |
