| 1 | Transmission routes of 2019-nCoV and controlsin dental practice显示文摘A novel β-coronavirus(2019-nCoV) caused severe and even fatal pneumonia explored in a seafood market of Wuhan city, Hubei province, China, and rapidly spread to other provinces of China and other countries. The 2019-nCoV was different from SARS-Co V,but shared the same host receptor the human angiotensin-converting enzyme 2(ACE2). The natural host of 2019-nCoV may be the bat Rhinolophus affinis as 2019-nCoV showed 96.2% of whole-genome identity to Bat Co V Ra TG13. The person-to-person transmission routes of 2019-nCoV included direct transmission, such as cough, sneeze, droplet inhalation transmission, and contact transmission, such as the contact with oral, nasal, and eye mucous membranes. 2019-nCoV can also be transmitted through the saliva, and the fecal–oral routes may also be a potential person-to-person transmission route. The participants in dental practice expose to tremendous risk of 2019-nCoV infection due to the face-to-face communication and the exposure to saliva, blood, and other body fluids, and the handling of sharp instruments. Dental professionals play great roles in preventing the transmission of2019-nCoV. Here we recommend the infection control measures during dental practice to block the person-to-person transmission routes in dental clinics and hospitals. | Xian Peng Xin Xu Yuqing Li Lei Cheng Xuedong Zhou Biao Ren | 2020 | International Journal of Oral Science2020,12,1: | 29 |
| 2 | Coping as a Mechanism Linking Stressful Life Events and Mental Health Problems in Adolescents显示文摘Objective Although stressful life events represent an etiologic factor of mental health problems in adolescents,few studies have been conducted to address mechanisms linking the stress‐psychopathology relation.The present study was designed to examine coping as a mediate factor on the relationship between stressful life events and symptoms of anxiety and depression.Methods The participants were 13 512 students from eight cities of China,who participated in a school‐based survey.Data were collected by a questionnaire comprising coping,stressful life events,anxiety,and depressive symptoms.As a model,a series of regression equations were used to examine whether coping mediated the association between stressful life events and symptoms of anxiety and depression.Results Each dimension of stressful life events showed significant correlation with anxiety,depression and coping (all P<0.001).In the model to analyze mediate effects,all standardized coefficients (β) were significant (all P<0.01),indicating marked mediator effects.Furthermore,negative coping might account for more mediate effects than positive coping on this relationship.Conclusion Coping partially mediated the relationship between stressful life events and mental health during adolescence.This study highlighted an important public health priority for preventive interventions targeting stress‐related psychopathology,and for further promoting adolescents'mental health. | MENG Xiu Hong TAO Fang Biao WAN Yu Hui HU Yan WANG Ren Xi | 2011 | Biomedical and Environmental Sciences2011,24,6: | 16 |
| 3 | Oral microbiota in human systematic diseases显示文摘Oral bacteria directly affect the disease status of dental caries and periodontal diseases. The dynamic oral microbiota cooperates with the host to reflect the information and status of immunity and metabolism through two-way communication along the oral cavity and the systemic organs. The oral cavity is one of the most important interaction windows between the human body and the environment.The microenvironment at different sites in the oral cavity has different microbial compositions and is regulated by complex signaling,hosts, and external environmental factors. These processes may affect or reflect human health because certain health states seem to be related to the composition of oral bacteria, and the destruction of the microbial community is related to systemic diseases. In this review, we discussed emerging and exciting evidence of complex and important connections between the oral microbes and multiple human systemic diseases, and the possible contribution of the oral microorganisms to systemic diseases. This review aims to enhance the interest to oral microbes on the whole human body, and also improve clinician’s understanding of the role of oral microbes in systemic diseases. Microbial research in dentistry potentially enhances our knowledge of the pathogenic mechanisms of oral diseases,and at the same time, continuous advances in this frontier field may lead to a tangible impact on human health. | Xian Peng Lei Cheng Yong You Chengwei Tang Biao Ren Yuqing Li Xin Xu Xuedong Zhou | 2022 | International Journal of Oral Science2022,14,1: | 9 |
| 4 | 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 |
| 5 | Oral bacteria colonize and compete with gut microbiota in gnotobiotic mice显示文摘The oral microbiota is associated with oral diseases and digestive systemic diseases.Nevertheless,the causal relationship between them has not been completely elucidated,and colonisation of the gut by oral bacteria is not clear due to the limitations of existing research models.The aim of this study was to develop a human oral microbiota-associated (HOMA) mouse model and to investigate the ecological invasion into the gut.By transplanting human saliva into germ-free (GF) mice,a HOMA mouse model was first constructed.16S rRNA gene sequencing was used to reveal the biogeography of oral bacteria along the cephalocaudal axis of the digestive tract.In the HOMA mice,84.78% of the detected genus-level taxa were specific to the donor.Principal component analysis (PCA) revealed that the donor oral microbiota clustered with those of the HOMA mice and were distinct from those of specific pathogen-free (SPF) mice.In HOMA mice,OTU counts decreased from the stomach and small intestine to the distal gut.The distal gut was dominated by Streptococcus,Veillonella,Haemophilus,Fusobacterium,Trichococcus and Actinomyces.HOMA mice and human microbiota-associated (HMA) mice along with the GF mice were then cohoused.Microbial communities of cohoused mice clustered together and were significantly separated from those of HOMA mice and HMA mice.The Source Tracker analysis and network analysis revealed more significant ecological invasion from oral bacteria in the small intestines,compared to the distal gut,of cohoused mice.In conclusion,a HOMA mouse model was successfully established.By overcoming the physical and microbial barrier,oral bacteria colonised the gut and profiled the gut microbiota,especially in the small intestine. | Bolei Li Yang Ge Lei Cheng Benhua Zeng Jinzhao Yu Xian Peng Jianhua Zhao Wenxia Li Biao Ren Mingyun Li Hong Wei Xuedong Zhou | 2019 | International Journal of Oral Science2019,11,3: | 7 |
| 6 | 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 |
| 7 | Elevated Plasma Tissue-type Plasminogen Activator (t-PA) and Soluble Throm-bomodulin in Patients Suffering From Severe Acute Respiratory Syndrome (SARS) as a Possible Index for Prognosis and Treatment Strategy显示文摘Objective To detect the presence of endothelial injury in patients with severe acute respiratory syndrome (SARS) via enhanced levels of tissue-type plasminogen activator (t-PA) and soluble thrombomodulin (sTM). Methods Case patients were from Xuanwu Hospital (Capital University of Medical Sciences, Beijing, China), and all of them met clinical criteria for SARS. Healthy controls were some of the hospital employees. Endothelial injury bio-markers tPA and sTM were detected by commercial ELISA-methods. Results Classic plasma markers of endothelial injury, tPA and sTM significantly elevated in SARS patients in comparison to controls [t-PA: 1.48±0.16 nmol/L versus 0.25±0.03 nmol/L (P<0.0001), and sTM: 0.26±0.06 nmol/L versus 0.14±0.02 nmol/L (P<0.05)]. The only patient who died had extremely high levels of these endothelial injury markers (t-PA: 2.77 nmol/L and sTM: 1.01 nmol/L). The likelihood ratio analysis indicated the excellent discriminating power for SARS at the optimal cut-point of 0.49 nmol/L for tPA and 0.20 nmol/L for sTM, respectively. Significant numerical correlations were found among these endothelial injury markers in SARS patients. The numerical coefficient of correlation Pearson r between t-PA and sTM was 0.5867 (P<0.05). Conclusion Increased plasma concentrations of tPA and sTM in patients with SARS suggest the possibility of endothelial injury. SARS patients might need anticoagulant therapy or fibrinolytic therapy in order to reverse intraalveolar coagulation, microthrombi formation, alveolar and interstitial fibrin deposition. It may not only provide a useful treatment and prognostic index but also allow a further understanding of the pathological condition of the disease. | ZHONG-HUA LIU RAN WEI YA-PING WU TON LISMAN ZENG-XIAN WANG JI-JU HAN DAO-LING REN BIN CHEN ZUO-LI XIA BIAO CHEN ZHEN ZHU YAN ZHANG XING CUI HAI-TAO HU PHILIP G.

| 8 | Sinogram denoising via attention residual dense convolutional neural network for low-dose computed tomography显示文摘The widespread use of computed tomography(CT)in clinical practice has made the public focus on the cumulative radiation dose delivered to patients.Low-dose CT(LDCT)reduces the X-ray radiation dose,yet compromises quality and decreases diagnostic performance.Researchers have made great efforts to develop various algorithms for LDCT and introduced deep-learning techniques,which have achieved impressive results.However,most of these methods are directly performed on reconstructed LDCT images,in which some subtle structures and details are readily lost during the reconstruction procedure,and convolutional neural network(CNN)-based methods for raw LDCT projection data are rarely reported.To address this problem,we adopted an attention residual dense CNN,referred to as AttRDN,for LDCT sinogram denoising.First,it was aided by the attention mechanism,in which the advantages of both feature fusion and global residual learning were used to extract noise from the contaminated LDCT sinograms.Then,the denoised sinogram was restored by subtracting the noise obtained from the input noisy sinogram.Finally,the CT image was reconstructed using filtered back-projection.The experimental results qualitatively and quantitatively demonstrate that the proposed AttRDN can achieve a better performance than state-of-the-art methods.Importantly,it can prevent the loss of detailed information and has the potential for clinical application. | Yin-Jin Ma Yong Ren Peng Feng Peng He Xiao-Dong Guo Biao Wei | 2021 | Nuclear Science and Techniques2021,32,4: | 2 |
| 9 | Quaternary ammonium-induced multidrug tolerant Streptococcus mutans persisters elevate cariogenic virulence in vitro显示文摘Dental caries are the most prevalent chronic infections in the oral cavity, and Streptococcus mutans acts as the main cariogenic bacterial species. Antibacterial quaternary ammonium compounds(QAs) have been developed to preve Fnt or treat dental caries.However, there is no report on the tolerance of S. mutans to QAs. In this study, we investigated the development of S. mutans persistence induced by a novel dental caries defensive agent, dimethylaminododecyl methacrylate(DMADDM), for the first time.Typical biphasic killing kinetics for persisters were observed in both S. mutans planktonic and biofilm cultures challenged by DMADDM at concentrations of 20 and 200 μg·m L^(-1), respectively. The persisters tolerated six other antibiotics with different antibacterial mechanisms, while only daptomycin and vancomycin could slightly reduce the persister numbers in planktonic cultures. The distribution of persisters in DMADDM-treated biofilms was similar to that in the untreated control, except that the total biomass and biofilm height were significantly reduced. A higher exopolysaccharides(EPS):bacteria ratio was observed in DMADDM-treated biofilms. Persisters in biofilms significantly upregulated gtf gene expression, indicating an increase in the bacteria's ability to produce EPS and an elevated capability of cariogenic virulence. Carbon source metabolism was significantly reduced, as related metabolic genes were all downregulated in persisters. Concentrations of 0.1 m M, 1 m M and 10 m M of extra glucose significantly reduced the number of persisters both in planktonic and biofilm conditions. The formation of noninheritable and multidrug tolerant persisters induced by DMADDM suggested that drug tolerance and new persistent eradication strategies should be considered for oral antibacterial agents. | Ya-Ling Jiang Wei Qiu Xue-Dong Zhou Hao Li Jun-Zhuo Lu Hockin HK Xu Xian Peng Ming-Yun Li Ming-Ye Feng Lei Cheng Biao Ren | 2017 | International Journal of Oral Science2017,9,4: | 2 |

| 12 | Reconfigurable metasurfaces that enable light polarization control by light显示文摘Plasmonic metasurfaces have recently attracted much attention because of their novel characteristics with respect to light polarization and wave front control on deep-subwavelength scales.The development of metasurfaces with reconfigurable optical responses is opening new opportunities in high-capacity communications,real-time holograms and adaptive optics.Such tunable devices have been developed in the mid-infrared spectral range and operated in light intensity modulation schemes.Here we present a novel optically reconfigurable hybrid metasurface that enables polarization tuning at optical frequencies.The functionality of tuning is realized by switching the coupling conditions between the plasmonic modes and the binary isomeric states of an ethyl red switching layer upon light stimulation.We achieved more than 20°nonlinear changes in the transmitted polarization azimuth using just 4 mW of switching light power.Such design schemes and principles could be easily applied to dynamically adjust the functionalities of other metasurfaces. | Meng-Xin Ren Wei Wu Wei Cai Biao Pi Xin-Zheng Zhang Jing-Jun Xu | 2016 | Light(Science & Applications)2016,5,1: | 1 |

| 17 | Beauvericin counteracted multi-drug resistant Candida albicans by blocking ABC transporters显示文摘Multi-drug resistance of pathogenic microorganisms is becoming a serious threat,particularly to immunocompromised populations.The high mortality of systematic fungal infections necessitates novel antifungal drugs and therapies.Unfortunately,with traditional drug discovery approaches,only echinocandins was approved by FDA as a new class of antifungals in the past two decades.Drug efflux is one of the major contributors to multi-drug resistance,the modulator of drug efflux pumps is considered as one of the keys to conquer multi-drug resistance.In this study,we combined structure-based virtual screening and whole-cell based mechanism study,identified a natural product,beauvericin(BEA)as a drug efflux pump modulator,which can reverse the multi-drug resistant phenotype of Candida albicans by specifically blocking the ATP-binding cassette(ABC)transporters;meantime,BEA alone has fungicidal activity in vitro by elevating intracellular calcium and reactive oxygen species(ROS).It was further demonstrated by histopathological study that BEA synergizes with a sub-therapeutic dose of ketoconazole(KTC)and could cure the murine model of disseminated candidiasis.Toxicity evaluation of BEA,including acute toxicity test,Ames test,and hERG(human ether-a-go-go-related gene)test promised that BEA can be harnessed for treatment of candidiasis,especially the candidiasis caused by ABC overexpressed multi-drug resistant C.albicans. | Yaojun Tong Mei Liu Yu Zhang Xueting Liu Ren Huang Fuhang Song Huanqin Dai Biao Ren Nuo Sun Gang Pei Jiang Bian Xin-Ming Jia Guanghua Huang Xuyu Zhou Shaojie Li Buchang Zhang Takashi Fukuda Hiroshi Tomoda SatoshiOmura Richard DCannon Richard Calderone Lixin Zhang | 2016 | Synthetic and Systems Biotechnology2016,1,3: | 1 |

| 19 | Suppressed recombination for monolithic inorganic perovskite/silicon tandem solar cells with an approximate efficiency of 23%显示文摘Potentially temperature-resistant inorganic perovskite/silicon tandem solar cells(TSCs)are promising devices for boosting efficiency past the single-junction silicon limit.However,undesirable non-radiative recombination generally leads to a significant voltage deficit.Here,we introduce an effective strategy using nickel iodide,an inorganic halide salt,to passivate iodine vacancies and suppress non-radiative recombination.NiI_(2)-treated CsPbI_(3-x)Br_(x) inor-ganic perovskite solar cells with a 1.80 eV bandgap exhibited an efficiency of 19.53%and a voltage of 1.36 V,corresponding to a voltage deficit of 0.44 V.Importantly,the treated device demonstrated excellent operational stability,maintaining 95.7%of its initial efficiency after maximum power point tracking for 300 h under continuous illumination in a N_(2) atmosphere.By combining this inorganic perovskite top cell with a narrower bandgap silicon bottom cell,we for the first time achieved monolithic inorganic perovskite/silicon TSCs,which exhibited an effi-ciency of 22.95%with an open-circuit voltage of 2.04 V.This work provides a promising strategy for using inorganic passivation materials to achieve efficient and stable solar cells. | Sanlong Wang Pengyang Wang Bingbing Chen Renjie Li Ningyu Ren Yucheng Li Biao Shi Qian Huang Ying Zhao Michael Grätzel Xiaodan Zhang | 2022 | eScience2022,2,3: | 1 |
