| 1 | CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19. | Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 9 |

| 3 | Assessment of the curving performance of heavy haul trains under braking conditions显示文摘To study the curving performance of trains,ID and 3D dynamic models of trains were built using numerical methods.The ID model was composed of 210 simple wagons,each allowed only longitudinal motion;whereas the 3D model included three complicated wagons for which longitudinal,lateral,and vertical degrees of freedom were considered.Combined with the calculated results from the ID model under braking conditions,the behavior of draft gears and brake shoes were added to the3 D model.The assessment of the curving performance of trains was focused on making comparisons between idling and braking conditions.The results indicated the following:when a train brakes on a curved track,the wheel-rail lateral force and derailment factor are greater than under idling conditions.Because the yawing movement of the wheelset is limited by brake shoes,the zone of wheel contact along the wheel tread is wider than under idling conditions.Furthermore,as the curvature becomes tighter,the traction ratio shows a nonlinear increasing trend,whether under idling or braking conditions.By increasing the brake shoe pressure,train steering becomes more difficult. | Liangliang Yang Yu Kang Shihui Luo Maohai Fu | 2015 | Journal of Modern Transportation2015，23，3： | 2 |

| 5 | A comparative study of alteration in retinal layer segmentation alteration by SD-OCT in neuromyelitis optica spectrum disorders: A systematic review and meta-analysis显示文摘Background:To evaluate the feature of different retinal layer segmentation in neuromyelitis optica spectrum disorders(NMOSD)with spectral-domain optical coherence tomography(SD-OCT)and to compare it with that in multiple sclerosis(MS),healthy controls(HC),and idiopathic optic neuritis(ION).Methods:We retrieved four electronic databases,including Pubmed,Embase,Cochrane Library,and Web of Science from inception to September 1st,2021.A meta-analysis was performed to compare different retinal layer segmentation thicknesses between patients with or without a history of optic neuritis(ON)in NMOSD and the control group,including patients with MS,HC,and ION.Results:Forty-two studies were included and the interval between the last ON onset and examination was greater than 3 months.Compared with that in HC eyes,the loss of retinal nerve fiber layer(RNFL)and macular ganglion cell and inner plexiform layer(GC-IPL)was serious in NMOSD eye especially after ON.Moreover,compared with that in ION eyes or MS-related-ON eyes,the injury to the peripapillary retinal nerve fiber layer(pRNFL)was severe in NMOSD-related-ON eyes.In addition,the correlation coefficient between pRNFL and prognostic visual acuity was 0.43.However,the one-arm study revealed the inner nuclear layer(INL)was thickened in NMOSDrelated-ON eyes compared with HC eyes.Conclusions:Inclusion of the RNFL and macular GC-IPL is recommended for monitoring disease progression and attention should be paid to changes in the INL. | Junxia Fu Shaoying Tan Chunxia Peng Huanfen Zhou Shihui Wei | 2021 | Advances in Ophthalmology Practice and Research2021，1，1： | 1 |
| 6 | The clinical application of critical flicker fusion frequency in demyelinating optic neuritis显示文摘Purpose:To investigate the application of critical flicker fusion frequency(CFF)in demyelinating optic neuritis(DON).Methods:A cross-sectional study.A total of 127 eyes in 69 DON patients and 63 eyes in 33 healthy control(HC)groups were included between January 2021 to September 2021 from Department of Ophthalmology,PLA General Hospital.Patients underwent best-corrected visual acuity(BCVA),visual field,optical coherence tomography(OCT),flash visual evoked potential(F-VEP),and CFF examinations.The affected eyes were divided into aquaporins 4(AQP4-),myelin oligodendrocyte glycoprotein(MOG-),and double negative DON according to serum antibody;mild,moderate,severe degree visual impairment according to BCVA0.5,0.1-0.5,<0.1;and 4 groups:<1,1~<3,3~<6 and>6 months according to time interval from onset to CFF examination.One-way ANOVA was used to perform above subgroup analysis.The correlations between CFF and F-VEP peak time,peak value,BCVA and mean visual filed defect(MD)were analyzed in order via Pearson correlation analysis.Results:he trichromatic values of red,green,and yellow in DON affected eyes were 21.83±9.03,23.66±10.21,24.09±10.77 Hz,respectively,which was significantly reduced compared with the HC group(t=-14.82,-14.22,-14.00;P<0.001).The subgroup analysis showed no significant difference between different antibody subtypes(P=0.914<0.848<0.604),whereas,a significant decrease of CFF trichromatic value was found in severe visual acuity impairment group(P<0.001).There was a significant difference in CFF-trichromatic values at different time points(P<0.001),to be specific,CFF fluctuated under 20Hz within 3 months after onset and tended to be stable around 24-28Hz.Correlation analysis showed that the peak time of F-VEP(r=-0.486,-0.515,-0.526;P<0.001),BVCA(r=-0.640,-0.659,-0.642;P<0.001),were negatively correlated with CFF trichromatic values,MD and CFF were positively correlated(r=0.486,0.453,0.476;P=0.003,0.006,0.004).Conclusions:A significant decrease of CFF value was found in DON-affected eyes,and it has a good correlation with BCVA,MD and latency of F-VEP,and can better reflect the impairment of visual function. | Junxia Fu Yongping Wang Shaoying Tan Guangcan Xu Huanfen Zhou Quangang Xu Shihui Wei | 2021 | Advances in Ophthalmology Practice and Research2021，1，2： | 0 |
| 7 | Differences in the involved sites among different types of demyelinating optic neuritis in traditional MRI examination:A systematic review and meta-analysis显示文摘Background:Magnetic resonance imaging(MRI)plays a significant role in assessing optic neuropathy and providing more detailed information about the lesion of the visual pathway to help differentiate optic neuritis from other visual disorders.This study aims to systematically review the literature and verify if there is a real difference in lesion location among different demyelinating optic neuritis(DON)subtypes.Methods:A systematic search was conducted including 8 electronic databases and related resources from the establishment of the database to August 25th,2020.We classified DON into 5 subtypes and divided the visual pathways into five segments mainly comparing the differences in the involved visual pathway sites of different subtypes.Results:Fifty-five studies were included in the analysis,and the abnormal rate was as high as 92%during the acute phase(within 4 weeks of symptom onset).With respect to lesion location,the orbital segment of the optic nerve was the most frequently involved(87%),whereas optic tract involvement was very rare.Involvement of the orbital segment was more common in myelin oligodendrocyte glycoprotein antibody-related optic neuritis(MOGON)(78%)and chronic relapsing inflammatory optic neuropathy(CRION)(81%),while the lesion was found to be located more posteriorly in neuromyelitis optica spectrum disorder-related optic neuritis(NMOSD-ON).With respect to lesion length,approximately 77%of MOG-ON patients had lesions involving more than half of the optic nerve length.Conclusions:MRI examination is recommended for DON patients in the acute phase.In MOG-ON,anterior involvement is more common and the involved length is mostly more than 1/2 of the optic nerve length,whereas posterior involvement,intracranial segment,optic chiasm,or optic tract,is more common in NMOSD-ON. | Yongping Wang Junxia Fu Honglu Song Quangang Xu Huanfen Zhou Shihui Wei | 2021 | Advances in Ophthalmology Practice and Research2021，1，2： | 0 |
| 8 | Stability and boundary equilibrium bifurcations of modified Chua's circuit with smooth degree of 3显示文摘Chua's circuit is a well-known nonlinear electronic model, having complicated nonsmooth dynamic behaviors. The stability and boundary equilibrium bifurcations for a modified Chua's circuit system with the smooth degree of 3 are studied. The parametric areas of stability are specified in detail. It is found that the bifurcation graphs of the supercritical and irregular pitchfork bifurcations are similar to those of the piecewise-smooth continuous(PWSC) systems caused by piecewise smoothness. However, the bifurcation graph of the supercritical Hopf bifurcation is similar to those of smooth systems. Therefore, the boundary equilibrium bifurcations of the non-smooth systems with the smooth degree of 3 should receive more attention due to their special features. | Shihui FU Xiangying MENG Qishao LU | 2015 | Applied Mathematics and Mechanics(English Edition)2015，36，12： | 0 |
| 9 | A GAN-based deep enhancer for quality enhancement of retinal images photographed by a handheld fundus camera显示文摘Objective:Due to limited imaging conditions,the quality of fundus images is often unsatisfactory,especially for images photographed by handheld fundus cameras.Here,we have developed an automated method based on combining two mirror-symmetric generative adversarial networks(GANs)for image enhancement.Methods:A total of 1047 retinal images were included.The raw images were enhanced by a GAN-based deep enhancer and another methods based on luminosity and contrast adjustment.All raw images and enhanced images were anonymously assessed and classified into 6 levels of quality classification by three experienced ophthalmologists.The quality classification and quality change of images were compared.In addition,imagedetailed reading results for the number of dubiously pathological fundi were also compared.Results:After GAN enhancement,42.9% of images increased their quality,37.5%remained stable,and 19.6%decreased.After excluding the images at the highest level(level 0)before enhancement,a large number(75.6%)of images showed an increase in quality classification,and only a minority(9.3%)showed a decrease.The GANenhanced method was superior for quality improvement over a luminosity and contrast adjustment method(P<0.001).In terms of image reading results,the consistency rate fluctuated from 86.6%to 95.6%,and for the specific disease subtypes,both discrepancy number and discrepancy rate were less than 15 and 15%,for two ophthalmologists.Conclusions:Learning the style of high-quality retinal images based on the proposed deep enhancer may be an effective way to improve the quality of retinal images photographed by handheld fundus cameras. | Junxia Fu Lvchen Cao Shihui Wei Ming Xub Yali Song Huiqi Li Yuxia You | 2022 | Advances in Ophthalmology Practice and Research2022，2，3： | 0 |

| 11 | Clinical characteristics of radiation-induced optic neuropathy:A single-center retrospective study显示文摘Purpose:To observe the clinical and imaging characteristics of radiation-induced optic neuropathy(RION).Methods:We retrospectively reviewed the clinical data of 43 patients(69 eyes)who were diagnosed with RION at the Chinese PLA General Hospital from 2010 to 2021.Results:The latency from radiotherapy to onset of visual loss ranged from 1 to 132(36.33±30.48)months.Optic disc pallor and optic disc edema were found in 27.0%(10/37)and 8.1%(3/37)of the eyes,respectively,within 2 months.After treatment,the best corrected visual acuity(BCVA)was restored in 24.6%(17/69)of the eyes and the final BCVA improved in 13.0%(9/69)of the eyes.An 82.5%(33/40)of the eyes with magnetic resonance imaging(MRI)showed enhancement of the affected optic nerve,mostly(69.7%)in the intracranial segment,and 36.4%(12/33)of the eyes with expansion and T2-high signals also showed enhancement of the affected optic nerve.The superior retinal nerve fiber layer(RNFL)and the outer circle superior quadrant(OS)of the inner limiting membrane to retinal pigment epithelium(ILM-RPE)layer thinned significantly during the first month.The center of the ILM-RPE layer thickened significantly during the first two months and the inner circle temporal quadrant(IT)of the ILM-RPE layer thickened significantly from the third to sixth month.The RNFL thinned significantly after 6 months except for the temporal quadrant,and the average inner circle superior quadrant(IS)and outer circle of the ILM-RPE layer thinned significantly after 6 months.There was no significant difference between hyperbaric oxygen therapy(HBOT)and high-dose intravenous methylprednisolone(IVMP)therapy in improving BCVA recovery or final BCVA(P>0.05).Conclusions:The structural damage of the RNFL and ILM-RPE layer occurred during the first month,the RNFL showed progressive thinning during the follow-up period,while the ILM-RPE layer showed thinning during the first month,thickening from the third to sixth month,and thinning after 6 months.There was a discrete region of enhancement of the optic nerve,often with expansion and high-T2 signals on MRI.HBOT and high-dose IVMP therapy were hardly effective for treating RION in the non-acute stage. | Yongping Wang Junxia Fu Huanfen Zhou Hongen Li Quangang Xu Shihui Wei | 2023 | Advances in Ophthalmology Practice and Research2023，3，3： | 0 |
| 12 | Inhibition of aryl hydrocarbon receptor signaling promotes the terminal differentiation of human erythroblasts显示文摘The aryl hydrocarbon receptor(AHR)plays an important role during mammalian embryo development.Inhibition of AHR signaling promotes the development of hematopoietic stem/progenitor cells.AHR also regulates the functional maturation of blood cells,such as T cells and megakaryocytes.However,little is known about the role of AHR modulation during the development of erythroid cells.In this study,we used the AHR antagonist StemRegenin 1(SR1)and the AHR agonist 2,3,7,8-tetrachlorodibenzo-p-dioxin during different stages of human erythropoiesis to elucidate the function of AHR.We found that antagonizing AHR signaling improved the production of human embryonic stem cell derived erythrocytes and enhanced erythroid terminal differentiation.RNA sequencing showed that SR1 treatment of proerythroblasts upregulated the expression of erythrocyte differentiation-related genes and downregulated actin organization-associated genes.We found that SR1 accelerated F-actin remodeling in terminally differentiated erythrocytes,favoring their maturation of the cytoskeleton and enucleation.We demonstrated that the effects of AHR inhibition on erythroid maturation were associated with F-actin remodeling.Our findings help uncover the mechanism for AHRmediated human erythroid cell differentiation.We also provide a new approach toward the large-scale production of functionally mature human pluripotent stem cell-derived erythrocytes for use in translational applications. | Yijin Chen Yong Dong Xulin Lu Wanjing Li Yimeng Zhang Bin Mao Xu Pan Xiaohong Li Ya Zhou Quanming An Fangxin Xie Shihui Wang Yuan Xue Xinping Cai Mowen Lai Qiongxiu Zhou Yan Yan Ruohan Fu Hong Wang Tatsutoshi Nakahata Xiuli An Lihong Shi Yonggang Zhang Feng Ma | 2022 | Journal of Molecular Cell Biology2022，14，2： | 0 |
