| 2 | Cold-chain food contamination as the possible origin of COVID-19 resurgence in Beijing显示文摘COVID-19,caused by SARS-CoV-2[1,2],has been contained in China through stringent non-pharmaceutical interventions.Border control and quarantine have effectively prevented the virus from being spread by infected travellers,but the risk of resurgence caused by other routes of introduction and transmission remains unclear,and current strategies to prevent resurgence could be flawed.Since July,SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China[3,4].However,there is no robust evidence of COVID-19 outbreaks initiated by environmentto-human transmission.Here we add to evidence of such transmission by investigating the recent COVID-19 resurgence in Beijing. | Xinghuo Pang Lili Ren Shuangsheng Wu Wentai Ma Jian Yang Lin Di Jie Li Yan Xiao Lu Kang Shichang Du Jing Du Jing Wang Gang Li Shuguang Zhai Lijuan Chen Wenxiong Zhou Shengjie Lai Lei Gao Yang Pan Quanyi Wang Mingkun Li Jianbin Wang Yanyi Huang Jianwei Wang COVID-19 Field Response Group COVID-19 Laboratory Testing Group | 2020 | National Science Review2020，7，12： | 51 |

| 4 | Bone Morphogenetic Protein (BMP) signaling in development and human diseases显示文摘Bone Morphogenetic Proteins(BMPs)are a group of signaling molecules that belongs to the Transforming Growth Factor-b(TGF-b)superfamily of proteins.Initially discovered for their ability to induce bone formation,BMPs are now known to play crucial roles in all organ systems.BMPs are important in embryogenesis and development,and also in maintenance of adult tissue homeostasis.Mouse knockout models of various components of the BMP signaling pathway result in embryonic lethality or marked defects,highlighting the essential functions of BMPs.In this review,we first outline the basic aspects of BMP signaling and then focus on genetically manipulated mouse knockout models that have helped elucidate the role of BMPs in development.A significant portion of this review is devoted to the prominent human pathologies associated with dysregulated BMP signaling. | Richard N.Wang Jordan Green Zhongliang Wang Youlin Deng Min Qiao Michael Peabody Qian Zhang Jixing Ye Zhengjian Yan Sahitya Denduluri Olumuyiwa Idowu Melissa Li Christine Shen Alan Hu Rex C.Haydon Richard Kang James Mok Michael J.Lee Hue L.Luu Lewis L.Shi | 2014 | Genes & Diseases2014，1，1： | 47 |
| 5 | Effects of Thinning and Litter Fall Removal on Fine Root Production and Soil Organic Carbon Content in Masson Pine Plantations显示文摘Soils play a critical role in the global carbon cycle, and can be major source or sink of CO2 depending upon land use, vegetation type and soil management practices. Fine roots are important component of a forest ecosystem in terms of water and nutrient uptake. In this study the effects of thinning and litter fall removal on fine root production and soil organic carbon content were examined in 20-year-old Masson pine (Pinus resinosa) plantations in Huitong, Hunan Province of China in the growing seasons of 2004 and 2005. The results showed that fine root production was significantly lower in the thinning plots than in the control plots, with a decrease of 58% and 14% in 2004 and 2005 growing seasons, respectively. Litter fall removal significantly increased fine root production by 14% in 2004. Soil temperature (Tsoil) and soil moisture (Msoil) were higher in the thinning plots than those in the controls. Litter fall removal had significant effiects on Tsoil and Msoil. Soil organic carbon content was higher in the thinning plots but was lower in the plots with litter fall removal compared with that in the controls. Our results also indicated that annual production of fine roots resulted in small carbon accumulation in the upper layers of the soil, and removal of tree by thinning resulted in a significant increase of carbon storage in Masson pine plantations. | TIAN Da-Lun PENG Yuan-Ying YAN Wen-De FANG Xi KANG Wen-Xing WANG Guang-Jun CHEN Xiao-Yong | 2010 | Pedosphere2010，20，4： | 36 |

| 8 | Climate change over the Yarlung Zangbo River Basin during 1961-2005显示文摘The Yarlung Zangbo River (YR) is the highest great river in the world, and its basin is one of the centers of human economic activity in Tibet. Using 10 meteorological stations over the YR basin in 1961–2005, the spatial and temporal characteristics of temperature and precipitation as well as potential evapotranspiration are analyzed. The results are as follows. (1) The annual and four seasonal mean air temperature shows statistically significant increasing trend, the tendency is more significant in winter and fall. The warming in Lhasa river basin is most significant. (2) The precipitation is decreasing from the 1960s to the 1980s and increasing since the 1980s. From 1961 to 2005, the annual and four seasonal mean precipitation is increasing but not statistically significant, especially in fall and spring. The increasing precipitation rates are more pronounced in Niyangqu and Palong Zangbo river basins, the closer to the upper YR is, the less precipitation increasing rate would be. (3) The annual and four seasonal mean potential evapotranspiration has decreased, especially after the 1980s, and most of it happens in winter and spring. The decreasing trend is most significant in the middle YR and Nianchu river basin. (4) Compared with the Mt. Qomolangma region, Tibetan Plateau, China and global average, the magnitudes of warming trend over the YR basin since the 1970s exceed those areas in the same period, and compared with the Tibetan Plateau, the magnitudes of precipitation increasing and potential evapotranspiration decreasing are larger, suggesting that the YR basin is one of the most sensitive areas to global warming. | YOU Qinglong KANG Shichang WU Yanhong YAN Yuping | 2007 | Journal of Geographical Sciences2007，17，4： | 25 |
| 9 | Effects of penehyclidine hydrochloride in small intestinal damage caused by limb ischemia-reperfusion显示文摘AIM:To investigate the protective effect of penehyclidine hydrochloride post-conditioning in the damage to the barrier function of the small intestinal mucosa caused by limb ischemia-reperfusion(LIR) injury. METHODS:Male Wistar rats were randomly divided into three groups(36 rats each) :the sham-operation group(group S) ,lower limb ischemia-reperfusion group(group LIR) ,and penehyclidine hydrochloride postconditioning group(group PHC) .Each group was divided into subgroups(n=6 in each group) according to ischemic-reperfusion time,i.e.immediately 0 h(T1) ,1 h(T2) ,3 h(T3) ,6 h(T4) ,12 h(T5) ,and 24 h(T6) .Bilateral hind-limb ischemia was induced by rubber band application proximal to the level of the greater trochanter for 3 h.In group PHC,0.15 mg/kg of penehyclidine hydrochloride was injected into the tail vein immediately after 3 h of bilateral hind-limb ischemia.The designated rats were sacrificed at different time-points of reperfusion;diamine oxidase(DAO) ,superoxide dismutase(SOD) activity,myeloperoxidase(MPO) of small intestinal tissue,plasma endotoxin,DAO,tumor necrosis factor-α(TNF-α) ,and interleukin(IL) -10 in serum were detected in the rats. RESULTS:The pathological changes in the small intestine were observed under light microscope.The levels of MPO,endotoxin,serum DAO,and IL-10 at T1-T6,and TNF-αlevel at T1-T4 increased in groups LIR and PHC(P<0.05) compared with those in group S,but tissue DAO and SOD activity at T1-T6 decreased(P<0.05) .In group PHC,the tissue DAO and SOD activity at T2-T6,and IL-10 at T2-T5 increased to higher levels than those in group LIR(P<0.05) ;however,the levels of MPO,endotoxin,and DAO in the blood at T2-T6,and TNF-αat T2 and T4 decreased(P<0.05) . CONCLUSION:Penehyclidine hydrochloride post-conditioning may reduce the permeability of the small intestines after LIR.Its protection mechanisms may be related to inhibiting oxygen free radicals and inflammatory cytokines for organ damage. | Yan Zhang Yu-Fang Leng Xing Xue Yue Zhang Tao Wang Yu-Qing Kang | 2011 | World Journal of Gastroenterology2011，17，2： | 25 |

| 11 | A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield. | Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian | 2020 | Molecular Plant2020，13，6： | 23 |
| 12 | Role of PERK/eIF2α/CHOP Endoplasmic Reticulum Stress Pathway in Oxidized Low-density Lipoprotein Mediated Induction of Endothelial Apoptosis显示文摘Objective PERK/eI F2α/CHOP is a major signaling pathway mediating endoplasmic reticulum(ER) stress related with atherosclerosis.Oxidized LDL(ox-LDL) also induces endothelial apoptosis and plays a vital role in the initiation and progression of atherosclerosis.The present study was conducted to explore the regulatory effect of ox-LDL on PERK/e IF2α/CHOP signaling pathway in vascular endothelial cells.Methods The effects of ox-LDL on PERK and p-e IF2α protein expression of primary human umbilical vein endothelial cells(HUVECs) were investigated by Western blot analysis.PERK gene silencing and selective eI F2α phosphatase inhibitor,salubrinal were used to inhibit the process of ox-LDL induced endothelial cell apoptosis,caspase-3 activity,and CHOP mR NA level.Results Ox-LDL treatment significantly increased the expression of PERK,PERK-mediated inactivation of e IF2α phosphorylation,and the expression of CHOP,as well as the caspase-3 activity and apoptosis.The effects of ox-LDL were markedly decreased by knocking down PERK with stable transduction of lentiviral sh RNA or by selective eI F2α phosphatase inhibitor,salubrinal.Conclusion This study provides the first evidence that ox-LDL induces apoptosis in vascular endothelial cells mediated largely via the PERK/eI F2α/CHOP ER-stress pathway.It adds new insights into the molecular mechanisms underlying the pathogenesis and progression of atherosclerosis. | TAO Yong Kang YU Pu Lin BAI Yong Ping YAN Sheng Tao ZHAO Shui Ping ZHANG Guo Qiang | 2016 | Biomedical and Environmental Sciences2016，29，12： | 21 |
| 13 | Panax ginseng extract attenuates neuronal injury and cognitive deficits in rats with vascular dementia induced by chronic cerebral hypoperfusion显示文摘Panax ginseng is a slow-growing perennial plant.Panax ginseng extract has numerous biological activities,including antitumor,anti-inflammatory and antistress activities.Panax ginseng extract also has a cognition-enhancing effect in rats with alcohol-induced memory impairment.In this study,we partially occluded the bilateral carotid arteries in the rat to induce chronic cerebral hypoperfusion,a wellknown model of vascular dementia.The rats were then intragastrically administered 50 or 100 mg/kg Panax ginseng extract.Morris water maze and balance beam tests were used to evaluate memory deficits and motor function,respectively.Protein quantity was used to evaluate cholinergic neurons.Immunofluorescence staining was used to assess the number of glial fibrillary acidic protein-positive cells.Western blot assay was used to evaluate protein levels of vascular endothelial growth factor,basic fibroblast growth factor,Bcl-2 and Bax.Treatment with Panax ginseng extract for 8 weeks significantly improved behavioral function and increased neuronal density and VEGF and b FGF protein expression in the hippocampal CA3 area.Furthermore,Panax ginseng extract reduced the number of glial fibrillary acidic protein-immunoreactive cells,and it decreased apoptosis by upregulating Bcl-2 and downregulating Bax protein expression.The effect of Panax ginseng extract was dose-dependent and similar to that of nimodipine,a commonly used drug for the treatment of vascular dementia.These findings suggest that Panax ginseng extract is neuroprotective against vascular dementia induced by chronic cerebral hypoperfusion,and therefore might have therapeutic potential for preventing and treating the disease. | Jun-De Zhu Jun-Jie Wang Xian-Hu Zhang Yan Yu Zhao-Sheng Kang | 2018 | Neural Regeneration Research2018，13，4： | 21 |

| 15 | The versatile functions of Sox9 in development,stem cells,and human diseases显示文摘The transcription factor Sox9 was first discovered in patients with campomelic dysplasia,a haploinsufficiency disorder with skeletal deformities caused by dysregulation of Sox9 expression during chondrogenesis.Since then,its role as a cell fate determiner during embryonic development has been well characterized;Sox9 expression differentiates cells derived from all three germ layers into a large variety of specialized tissues and organs.However,recent data has shown that ectoderm-and endoderm-derived tissues continue to express Sox9 in mature organs and stem cell pools,suggesting its role in cell maintenance and specification during adult life.The versatility of Sox9 may be explained by a combination of posttranscriptional modifications,binding partners,and the tissue type in which it is expressed.Considering its importance during both development and adult life,it follows that dysregulation of Sox9 has been implicated in various congenital and acquired diseases,including fibrosis and cancer.This review provides a summary of the various roles of Sox9 in cell fate specification,stem cell biology,and related human diseases.Ultimately,understanding the mechanisms that regulate Sox9 will be crucial for developing effective therapies to treat disease caused by stem cell dysregulation or even reverse organ damage. | Alice Jo Sahitya Denduluri Bosi Zhang Zhongliang Wang Liangjun Yin Zhengjian Yan Richard Kang Lewis L.Shi James Mok Michael J.Lee Rex C.Haydon | 2014 | Genes & Diseases2014，1，2： | 16 |
| 16 | Biological Cycles of Mineral Elements in a Young Mixed Stand in Abandoned Mining Soils显示文摘Phytoremediation as a sustainable and inexpensive technology based on the removal of pollutants from the environmentby plants is becoming an increasingly important objective in plant research.In this study,biological cycles of five nutrientelements(N,P,K,Ca,and Mg)and eight heavy metal elements(Fe,Cu,Zn,Mn,Cd,Ni,Pb and Co)were examined in youngpaniculed goldraintree(Koelreuteria paniculata Laxm)and common elaeocarpus(Elaeocarpus decipens)mixed standsin an abandoned mining area.We found that after vegetation restoration in abandoned mining areas,the organic matterand concentrations of nutrient elements were significantly increased and the heavy metal elements were significantlydecreased,the annual retention,uptake and return were 75.0,115.4,and 40.3 kg/hm^2 for nutrient elements,and 1878.0,3231.0 and 1353.0 g/hm^2 for heavy metal elements,respectively,with the utilization coefficient,cycling coefficient andturnover rate of 0.92,0.35 and 0.32 for nutrient elements,and 1.24,0.42 and 1.92 for heavy metal elements,respectively.Our results suggested that the vegetation restoration in abandoned mining areas had significant effects in improvingenvironmental conditions,enhancing soil available nutrients,and ensuring human health. | Da-Lun Tian Wen-Hua Xiang Wen-De Yan Wen-Xing Kang Xiang-Wen Deng Zhu Fan | 2007 | Journal of Integrative Plant Biology2007，49，9： | 14 |

| 18 | Urban garbage disposal and management in China显示文摘This paper, probing into the present situation of urban domestic garbage by analyzing its growing trend, compositional change and regional difference, reveals the problems existing in its disposal and management in China. Meanwhile, a questionnaire was conducted in five big cities around China for surveying urban residents’ attitudes towards garbage disposal and management policies and measures. Results showed the output of urban domestic garbage in Chinese cities is ever increasing, and the recoverable materials and energy in garbage composition are also increasing. The population growth, economic development, and increase of residents’ expenditure level are the main factors influencing the growing output and changing composition of the garbage. Information acquired from the questionnaire showed that majority of the urban residents are in favor of the garbage reduction policies and managerial measures and are willing to collaborate with municipal government in battling against garbage. Based on the analysis and questionnaire, some policymaking oriented suggestions such as operating the garbage disposal from a social welfare service to a sector of profit gaining enterprises, transferring the garbage management from passive end control to active source control, promoting the classified garbage collection in cities around China, and charging garbage fees for its cleanup and disposal, have also been put forward in the paper. | JIANG Yuan, KANG Mu yi *, LIU Zheng, ZHOU Yan fang (Institute of Resources Science, Beijing Normal University, Beijing 100875, China. | 2003 | Journal of Environmental Sciences2003，15，4： | 14 |
| 19 | Binding Activity Difference of Anti-CD20 scFv-Fc Fusion Protein Derived from Variable Domain Exchange显示文摘Two novel engineered antibody fragments binding to antigen CD20 were generated by fusing a murine IgM-type anti-CD20 single-chain Fv fragment (scFv) to the human IgG1 CH2 (i.e., Cγ2) and CH3 (i.e., Cγ3) domains with the human IgG1 hinge (i.e. Hγ). Given the relationship between structure and function of protein, the 3-D structures of the two engineered antibody fragments were modeled using computer-aided homology modeling method. Furthermore, the relationship between 3-D conformation and their binding activity was evaluated theoretically. Due to the change of active pocket formed by CDRs, the HL23 (VH-Linker-VL-Hγ-Cγ2-Cγ3) remained its activity because of its preserved conformation, while the binding activity of the LH23 (VL-Linker-VH-Hγ-Cγ2-Cγ3) was impaired severely. Experimental studies by flow cytometry and fluorescence microscopy showed that HL23 possessed significantly superior binding activity to CD20-expressing target cells than LH23. That is to say, the order of variable regions could influence the binding activity of the fusion protein to CD20+ cell lines, which was in accordance with the theoretical results. The study highlights the potential relationship between the antibody binding activity and their 3-D conformation, which appears to be worthwhile in providing direction for future antibody design of recombinant antibody. | Shusheng Geng Jiannan Feng Yan Li Yingxun Sun Xin Gu Ying Huang Yugang Wang Xianjiang Kang Hong Chang Beifen Shen | 2006 | Cellular & Molecular Immunology2006，3，6： | 13 |
| 20 | Myelin Oligodendrocyte Glycoprotein-IgG Contributes to Oligodendrocytopathy in the Presence of Complement, Distinct from Astrocytopathy Induced by AQP4-IgG显示文摘Immunoglobulin G against myelin oligodendrocyte glycoprotein(MOG-Ig G) is detectable in neuromyelitis optica spectrum disorder(NMOSD) without aquaporin-4 Ig G(AQP4-Ig G), but its pathogenicity remains unclear.In this study, we explored the pathogenic mechanisms of MOG-Ig G in vitro and in vivo and compared them with those of AQP4-Ig G. MOG-Ig G-positive serum induced complement activation and cell death in human embryonic kidney(HEK)-293 T cells transfected with human MOG. In C57 BL/6 mice and Sprague-Dawley rats, MOG-Ig G only caused lesions in the presence of complement. Interestingly, AQP4-Ig G induced astroglial damage, while MOGIg G mainly caused myelin loss. MOG-Ig G also induced astrocyte damage in mouse brains in the presence ofcomplement. Importantly, we also observed ultrastructural changes induced by MOG-Ig G and AQP4-Ig G. These findings suggest that MOG-Ig G directly mediates cell death by activating complement in vitro and producing NMOSDlike lesions in vivo. AQP4-Ig G directly targets astrocytes,while MOG-Ig G mainly damages oligodendrocytes. | Ling Fang Xinmei Kang Zhen Wang Shisi Wang Jingqi Wang Yifan Zhou Chen Chen Xiaobo Sun Yaping Yan Allan G.
