| 1 | Saliva: potential diagnostic value and transmission of 2019-nCoV显示文摘2019-n Co V epidemic was firstly reported at late December of 2019 and has caused a global outbreak of COVID-19 now.Saliva,a biofluid largely generated from salivary glands in oral cavity,has been reported 2019-n Co V nucleic acid positive.Besides lungs,salivary glands and tongue are possibly another hosts of 2019-n Co V due to expression of ACE2.Close contact or short-range transmission of infectious saliva droplets is a primary mode for 2019-n Co V to disseminate as claimed by WHO,while long-distance saliva aerosol transmission is highly environment dependent within indoor space with aerosol-generating procedures such as dental practice.So far,no direct evidence has been found that 2019-n Co V is vital in air flow for long time.Therefore,to prevent formation of infectious saliva droplets,to thoroughly disinfect indoor air and to block acquisition of saliva droplets could slow down2019-n Co V dissemination.This review summarizes diagnostic value of saliva for 2019-n Co V,possibly direct invasion into oral tissues,and close contact transmission of 2019-n Co V by saliva droplets,expecting to contribute to 2019-n Co V epidemic control. | Ruoshi Xu Bomiao Cui Xiaobo Duan Ping Zhang Xuedong Zhou Quan Yuan | 2020 | International Journal of Oral Science2020，12，2： | 9 |
| 2 | AFF4 regulates osteogenic differentiation of human dental follicle cells显示文摘As a member of the AFF(AF4/FMR2)family,AFF4 is a transcription elongation factor that is a component of the super elongation complex.AFF4 serves as a scaffolding protein that connects transcription factors and promotes gene transcription through elongation and chromatin remodelling.Here,we investigated the effect of AFF4 on human dental follicle cells(DFCs)in osteogenic differentiation.In this study,we found that small interfering RNA-mediated depletion of AFF4 resulted in decreased alkaline phosphatase(ALP)activity and impaired mineralization.In addition,the expression of osteogenic-related genes(DLX5,SP7,RUNX2 and BGLAP)was significantly downregulated.In contrast,lentivirus-mediated overexpression of AFF4 significantly enhanced the osteogenic potential of human DFCs.Mechanistically,we found that both the mRNA and protein levels of ALKBH1,a critical regulator of epigenetics,changed in accordance with AFF4 expression levels.Overexpression of ALKBH1 in AFF4-depleted DFCs partially rescued the impairment of osteogenic differentiation.Our data indicated that AFF4 promoted the osteogenic differentiation of DFCs by upregulating the transcription of ALKBH1. | Qingyue Xiao Yuning Zhang Xingying Qi Yaqian Chen Rui Sheng Ruoshi Xu Quan Yuan Chenchen Zhou | 2020 | International Journal of Oral Science2020，12，4： | 4 |
| 3 | Klotho in Osx+-mesenchymal progenitors exerts pro-osteogenic and anti-inflammatory effects during mandibular alveolar bone formation and repair显示文摘Maxillofacial bone defects are commonly seen in clinical practice.A clearer understanding of the regulatory network directing maxillofacial bone formation will promote the development of novel therapeutic approaches for bone regeneration.The fibroblast growth factor(FGF)signalling pathway is critical for the development of maxillofacial bone.Klotho,a type I transmembrane protein,is an important components of FGF receptor complexes.Recent studies have reported the presence of Klotho expression in bone.However,the role of Klotho in cranioskeletal development and repair remains unknown.Here,we use a genetic strategy to report that deletion of Klotho in Osx-positive mesenchymal progenitors leads to a significant reduction in osteogenesis under physiological and pathological conditions.Klotho-deficient mensenchymal progenitors also suppress osteoclastogenesis in vitro and in vivo.Under conditions of inflammation and trauma-induced bone loss,we find that Klotho exerts an inhibitory function on inflammation-induced TNFR signaling by attenuating Rankl expression.More importantly,we show for the first time that Klotho is present in human alveolar bone,with a distinct expression pattern under both normal and pathological conditions.In summary,our results identify the mechanism whereby Klotho expressed in Osx+-mensenchymal progenitors controls osteoblast differentiation and osteoclastogenesis during mandibular alveolar bone formation and repair.Klotho-mediated signaling is an important component of alveolar bone remodeling and regeneration.It may also be a target for future therapeutics. | Yi Fan Chen Cui Clifford JRosen Tadatoshi Sato Ruoshi Xu Peiran Li Xi Wei Ruiye Bi Quan Yuan Chenchen Zhou | 2022 | Signal Transduction and Targeted Therapy2022，7，6： | 3 |
| 4 | Genomic and transcriptomic analysis unveils population evolution and development of pesticide resistance in fall armyworm Spodoptera frugiperda显示文摘The fall armyworm(FAW),Spodoptera frugiperda,is a destructive pest native to America and has recently become an invasive insect pest in China.Because of its rapid spread and great risks in China,understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies.Here,we assembled a chromosome-level genome of a male FAW(SFynMstLFR)and compared re-sequencing results of the populations from America,Africa,and China.Strain identification of 163 individuals collected from America,Africa and China showed that both C and R strains were found in the American pop-ulations,while only C strain was found in the Chinese and African populations.Moreover,population geno-mics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations.Taken toge-ther,FAWs invaded into China were most likely origi-nated from Africa.Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW,of which 283 genes are specific to FAW.Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles,and several detoxification genes such as AOX,UGT and GST spe-cially responded to the pesticides.These findings will be useful in developing effective strategies for manage-ment of FAW in China and other invaded areas. | Furong Gui Tianming Lan Yue Zhao Wei Guo Yang Dong Dongming Fang Huan Liu Haimeng Li Hongli Wang Ruoshi Hao Xiaofang Cheng Yahong Li Pengcheng Yang Sunil Kumar Sahu Yaping Chen Le Cheng Shuqi He Ping Liu Guangyi Fan Haorong Lu Guohai Hu Wei Dong Bin Chen Yuan Jiang Yongwei Zhang Hanhong Xu Fei Lin Bernard Slippers Alisa Postma Matthew Jackson Birhan Addisie Abate Kassahun Tesfaye Aschalew Lemma Demie Meseret Destaw Bayeleygne Dawit Tesfaye Degefu Feng Chen Paul K.Kuria Zachary M.Kinyua Tong-Xian Liu Huanming Yang Fangneng Huang Xin Liu Jun Sheng Le Kang | 2022 | Protein & Cell2022，13，7： | 2 |
| 5 | METTL3-mediated m^(6)A RNA methylation regulates dorsal lingual epithelium homeostasis显示文摘The dorsal lingual epithelium,which is composed of taste buds and keratinocytes differentiated from K14^(+)basal cells,discriminates taste compounds and maintains the epithelial barrier.N6-methyladenosine(m^(6)A)is the most abundant mRNA modification in eukaryotic cells.How METTL3-mediated m^(6)A modification regulates K14^(+)basal cell fate during dorsal lingual epithelium formation and regeneration remains unclear.Here we show knockout of Mettl3 in K14^(+)cells reduced the taste buds and enhanced keratinocytes.Deletion of Mettl3 led to increased basal cell proliferation and decreased cell division in taste buds.Conditional Mettl3 knock-in mice showed little impact on taste buds or keratinization,but displayed increased proliferation of cells around taste buds in a protective manner during post-irradiation recovery.Mechanically,we revealed that the most frequent m^(6)A modifications were enriched in Hippo and Wnt signaling,and specific peaks were observed near the stop codons of Lats1 and FZD7.Our study elucidates that METTL3 is essential for taste bud formation and could promote the quantity recovery of taste bud after radiation. | Qiuchan Xiong Caojie Liu Xin Zheng Xinyi Zhou Kexin Lei Xiaohan Zhang Qian Wang Weimin Lin Ruizhan Tong Ruoshi Xu Quan Yuan | 2022 | International Journal of Oral Science2022，14，3： | 2 |
| 6 | Insights into skeletal stem cells显示文摘The tissue-resident skeletal stem cells(SSCs),which are self-renewal and multipotent,continuously provide cells(including chondrocytes,bone cells,marrow adipocytes,and stromal cells)for the development and homeostasis of the skeletal system.In recent decade,utilizing fluorescence-activated cell sorting,lineage tracing,and single-cell sequencing,studies have identified various types of SSCs,plotted the lineage commitment trajectory,and partially revealed their properties under physiological and pathological conditions.In this review,we retrospect to SSCs identification and functional studies.We discuss the principles and approaches to identify bona fide SSCs,highlighting pioneering findings that plot the lineage atlas of SSCs.The roles of SSCs and progenitors in long bone,craniofacial tissues,and periosteum are systematically discussed.We further focus on disputes and challenges in SSC research. | Qiwen Li Ruoshi Xu Kexin Lei Quan Yuan | 2022 | Bone Research2022，10，4： | 2 |

| 9 | Decoding early myelopoiesis from dynamics of core endogenous network显示文摘A decade ago mainstream molecular biologists regarded it impossible or biologically ill-motivated to understand the dynamics of complex biological phenomena, such as cancer genesis and progression, from a network perspective. Indeed, there are numerical difficulties even for those who were determined to explore along this direction. Undeterred, seven years ago a group of Chinese scientists started a program aiming to obtain quantitative connections between tumors and network dynamics. Many interesting results have been obtained. In this paper we wish to test such idea from a different angle: the connection between a normal biological process and the network dynamics. We have taken early myelopoiesis as our biological model. A standard roadmap for the cell-fate diversification during hematopoiesis has already been well established experimentally, yet little was known for its underpinning dynamical mechanisms. Compounding this difficulty there were additional experimental challenges, such as the seemingly conflicting hematopoietic roadmaps and the cell-fate inter-conversion events. With early myeloid cell-fate determination in mind, we constructed a core molecular endogenous network from well-documented gene regulation and signal transduction knowledge. Turning the network into a set of dynamical equations, we found computationally several structurally robust states. Those states nicely correspond to known cell phenotypes. We also found the states connecting those stable states.They reveal the developmental routes—how one stable state would most likely turn into another stable state. Such interconnected network among stable states enabled a natural organization of cell-fates into a multi-stable state landscape. Accordingly, both the myeloid cell phenotypes and the standard roadmap were explained mechanistically in a straightforward manner. Furthermore,recent challenging observations were also explained naturally. Moreover, the landscape visually enables a prediction of a pool of additional cell states and developmental routes, including the non-sequential and cross-branch transitions, which are testable by future experiments. In summary, the endogenous network dynamics provide an integrated quantitative framework to understand the heterogeneity and lineage commitment in myeloid progenitors. | Hang Su Gaowei Wang Ruoshi Yuan Junqiang Wang Ying Tang Ping Ao Xiaomei Zhu | 2017 | Science China(Life Sciences)2017，60，6： | 1 |
| 10 | Interaction between pollution and climate change augments ecological risk to a coastal ecosystem显示文摘Pollution and climate change are among the most challenging issues for countries with developing economies,but we know little about the ecological risks that result when these pressures occur together.We explored direct effects of,and interactions between,environmental pollution and climate change on ecosystem health in the Bohai Sea region of Northern China.We developed an integrated approach to assess ecological risks to this region under four scenarios of climate change.Although ecological risks to the system from pollution alone have been declining,interactions between pollution and climate change have enhanced ecological risks to this coastal/marine ecosystem.Our results suggest that current policies focused strictly on pollution control alone should be changed to take into account the interactive effects of climate change so as to better forecast and manage potential ecological risks. | Yonglong Lu Ruoshi Wang Yajuan Shi Chao Su Jingjing Yuan Andrew C.Johnson Alan Jenkins Robert C.Ferrier Deliang Chen Hanqin Tian Jerry Melillo Shuai Song Aaron M.Ellison | 2018 | Ecosystem Health and Sustainability2018，4，7： | 0 |
| 11 | Application of nano-patterned InGaN fabricated by selfassembled Ni nano-masks in green InGaN/GaN multiple quantum wells显示文摘The nano-patterned InGaN film was used in green InGaN/GaN multiple quantum wells(MQWs)structure,to relieve the unpleasantly existing mismatch between high indium content InGaN and GaN,as well as to enhance the light output.The different self-assembled nano-masks were formed on InGaN by annealing thin Ni layers of different thicknesses.Whereafter,the InGaN films were etched into nano-patterned films.Compared with the green MQWs structure grown on untreated InGaN film,which on nano-patterned InGaN had better luminous performance.Among them the MQWs performed best when 3 nm thick Ni film was used as mask,because that optimally balanced the effects of nano-patterned InGaN on the crystal quality and the light output. | Ruoshi Peng Shengrui Xu Xiaomeng Fan Hongchang Tao Huake Su Yuan Gao Jincheng Zhang Yue Hao | 2023 | Journal of Semiconductors2023，44，4： | 0 |

| 13 | METTL5 regulates cranial suture fusion via Wnt signaling显示文摘METTL5 is a methyltransferase that mediates eukaryotic 18S ribosomal RNA m^(6)A modification,and its mutations lead to intellectual disability,microcephaly,and facial dysmorphism in patients.However,the role of METTL5 in craniofacial development remains poorly understood.This study demonstrates that Mettl5 knockout mice exhibit poor ossification,widened cranial sutures,and a cleidocranial dysplasia-like phenotype.Deletion of Mettl5 leads to increased proliferation and decreased osteogenic differentiation of suture mesenchymal stem cells.Mechanistically,we find that Wnt signaling is significantly downregulated after Mettl5 knockout.Overall,we reveal an essential role of METTL5 in craniofacial development and osteogenic differentiation of suture mesenchymal stem cells,making METTL5 a potential diagnostic and therapeutic target for craniofacial developmental diseases. | Kexin Lei Ruoshi Xu Qian Wang Qiuchan Xiong Xinyi Zhou Qiwen Li Dutmanee Seriwatanachai Shuibin Lin Chenchen Zhou Quan Yuan | 2023 | Fundamental Research2023，3，3： | 0 |
| 14 | Obstacle avoidance transplanting method on Kinect visual processing显示文摘In modern facility agriculture,to improve the quality and efficiency of transplanting,the application of transplanting robots based on visual processing is becoming more and more widespread.In order to reduce the damage to plants during the transplanting process and reduce the damage rate of plant stems,leaves and substrates,a transplanting method based on Kinect visual processing combined with an inclined transplanting manipulator was proposed.In the research,the Kinect visual processing was used to obtain and process the seedling height information and leaf edge information,and the working coordinate system of the transplanting manipulator was established and applied to plan the obstacle avoidance path.Combined with the oblique manipulator,the obstacle avoidance transplanting method was proposed.Through the structural design and force analysis of the seedling transplanting device,the key parameters that affect the transplanting quality were obtained,and the optimal transplanting performance parameters were obtained through experiments.In the experiment,with the aid of the Kinect vision processing system,the designed obstacle avoidance transplanting manipulator had a leaf damage degree of 4.70%,a stem bending rate of 16.67%,substrate integrity of 83.45%and a transplanting quality parameter of 87.36%.The time for a single seedling transplanting was(8.32±0.40)s.The experiment result proves that the obstacle avoidance transplanting method based on Kinect visual processing can effectively reduce the damage to seedlings when ensuring the transplanting efficiency. | Xin Jin Ruoshi Li Jiangtao Ji Yanwei Yuan Mingyong Li | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 0 |
