| 1 | Design and baseline data of a populationbased metabonomics study of eye diseases in eastern China: the Yueqing Ocular Diseases Investigation显示文摘Background:China is undergoing a massive transition toward an urban and industrial economy.These changes will restructure the demographics and economy which will eventually influence the future patterns of disease.The risk factors of vision-impairing eye diseases remain ambiguous and poorly understood.Metabolomics is an ideal tool to understand and shed light on the ocular disease mechanisms for earlier treatment.This article aims to describe the design,methodology and baseline data of the Yueqing Ocular Diseases Investigation(YODI),a developed county population-based study to determine the prevalence and primary causes of visual impairment;also with metabonomics analysis we aimed to identify,predict and suggest some preventive biomarkers that cause blindness.Methods:A population-based,cross-sectional study.Randomized clustering sampling was used to identify adults aged 50 years and older in Xiangyang Town,Yueqing county-level City.The interviews covered demographic,behavioral,ocular risk factors and mental health state.The ocular examination included visual acuity,autorefraction,intraocular pressure,anterior and posterior segment examinations,fundus photography,retinal tomography and angiography,and visual field testing.Anthropometric measurements included height and weight,waist and hip circumference,blood pressure,pulse rate,electrocardiogram,and abdominal ultrasound scan.A venous blood sample was collected for laboratory tests and metabonomics studies.Results:Of the 5319 individuals recruited for the YODI,4769(89.7%)subjects were enrolled for analyses.The median age was 62.0 years,and 45.6%were male.The educational level of illiteracy or semi-illiteracy,primary,middle and high school or above was 29.8%,45.5%,20.1%,and 3.3%,respectively.Majority of the participants were female,younger,and less educated when compared with nonparticipants.The average body mass index and waist-hip ratios were 24.4±3.4 kg/m^(2) and 0.9±0.1 respectively.Blood sample collection reached a sample size of 1909(479 from subjects with selfreported diabetes and 1430 from one-third of the 4290 subjects without self-reported diabetes).Conclusions:The YODI provides population-based data with a high response rate(89.7%)on the prevalence and primary causes of major vision-impairing eye diseases in developed county areas in eastern China.Metabonomics analysis from YODI will provide further association of metabolic characteristics with the visual impairment eye diseases.The risk prediction model could be created and has the potential to be generalized to developed eastern areas in China for prevention. | Yuxuan Deng Yuanbo Liang Sigeng Lin Liang Wen Jin Li Yue Zhou Meixiao Shen Jingwei Zheng Kemi Feng Yanting Sun Kwapong Willaim Robert Jia Qu Fan Lu | 2020 | Eye and Vision2020，7，1： | 4 |
| 2 | Reduced macular inner retinal thickness and microvascular density in the early stage of patients with dysthyroid optic neuropathy显示文摘Background:The goal was to investigate changes of the inner intra-retinal layer thicknesses and retinal capillary density(RCD)around the macula in thyroid-associated ophthalmopathy(TAO)patients with or without dysthyroid optic neuropathy(DON).Methods:Forty-four TAO patients including 23 non-DON and 21 DON patients,and 38 healthy participants were enrolled.Spectral domain optical coherence tomography equipped with Angiovue was used to obtain threedimensional retinal thickness maps and microvascular images of the superficial and deep retinal capillary layers(SRCL and DRCL,respectively)around the macula.Quantitative analyses were performed using a custom automated algorithm.Results:The thicknesses of the nerve fiber layer,ganglion cell layer+inner plexiform layer,and ganglion cell complex(GCC)as well as the RCDs in the SRCL and DRCL in both TAO groups were significantly decreased compared to the controls.In addition,the RCDs in DRCL of the DON group were further decreased compared to the non-DON group.GCC thickness in both TAO groups was positively correlated with the RCDs of the SRCL in the total annular zone and in the temporal,inferior,and nasal sectors.The areas under the receiver operating characteristic curves for the GCC thickness combined with the RCD were generally larger than those of each single indicator.Conclusions:Thinned inner intra-retinal layers and decreased RCDs in the TAO patients without DON revealed that morphological changes might precede visual dysfunction.The composite index of the retinal structure and the microvascular density might be valuable in the diagnosing,monitoring,and intervention for early DON. | Yufei Wu Yunhai Tu Chaoming Wu Lulu Bao Jianhua Wang Fan Lu Meixiao Shen Qi Chen | 2020 | Eye and Vision2020，7，1： | 3 |
| 3 | Machine learning helps improve diagnostic ability of subclinical keratoconus using Scheimpflug and OCT imaging modalities显示文摘Purpose:To develop an automated classification system using a machine learning classifier to distinguish clinically unaffected eyes in patients with keratoconus from a normal control population based on a combination of Scheimpflug camera images and ultra-high-resolution optical coherence tomography(UHR-OCT)imaging data.Methods:A total of 121 eyes from 121 participants were classified by 2 cornea experts into 3 groups:normal(50 eyes),with keratoconus(38 eyes)or with subclinical keratoconus(33 eyes).All eyes were imaged with a Scheimpflug camera and UHR-OCT.Corneal morphological features were extracted from the imaging data.A neural network was used to train a model based on these features to distinguish the eyes with subclinical keratoconus from normal eyes.Fisher’s score was used to rank the differentiable power of each feature.The receiver operating characteristic(ROC)curves were calculated to obtain the area under the ROC curves(AUCs).Results:The developed classification model used to combine all features from the Scheimpflug camera and UHR-OCT dramatically improved the differentiable power to discriminate between normal eyes and eyes with subclinical keratoconus(AUC=0.93).The variation in the thickness profile within each individual in the corneal epithelium extracted from UHR-OCT imaging ranked the highest in differentiating eyes with subclinical keratoconus from normal eyes.Conclusion:The automated classification system using machine learning based on the combination of Scheimpflug camera data and UHR-OCT imaging data showed excellent performance in discriminating eyes with subclinical keratoconus from normal eyes.The epithelial features extracted from the OCT images were the most valuable in the discrimination process.This classification system has the potential to improve the differentiable power of subclinical keratoconus and the efficiency of keratoconus screening. | Ce Shi Mengyi Wang Tiantian Zhu Ying Zhang Yufeng Ye Jun Jiang Sisi Chen Fan Lu Meixiao Shen | 2020 | Eye and Vision2020，7，1： | 3 |
| 4 | Antibody response and therapy in COVID-19 patients: what can be learned for vaccine development?显示文摘The newly emerged severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) has infected millions of people and caused tremendous morbidity and mortality worldwide. Effective treatment for coronavirus disease 2019(COVID-19) due to SARSCoV-2 infection is lacking, and different therapeutic strategies are under testing. Host humoral and cellular immunity to SARSCoV-2 infection is a critical determinant for patients’ outcomes. SARS-CoV-2 infection results in seroconversion and production of anti-SARS-CoV-2 antibodies. The antibodies may suppress viral replication through neutralization but might also participate in COVID-19 pathogenesis through a process termed antibody-dependent enhancement. Rapid progress has been made in the research of antibody response and therapy in COVID-19 patients, including characterization of the clinical features of antibody responses in different populations infected by SARS-CoV-2, treatment of COVID-19 patients with convalescent plasma and intravenous immunoglobin products, isolation and characterization of a large panel of monoclonal neutralizing antibodies and early clinical testing, as well as clinical results from several COVID-19 vaccine candidates. In this review, we summarize the recent progress and discuss the implications of these findings in vaccine development. | Ligong Lu Hui Zhang Meixiao Zhan Jun Jiang Hua Yin Danielle JDauphars Shi-You Li Yong Li You-Wen He | 2020 | Science China(Life Sciences)2020，63，12： | 3 |
| 5 | Preclinical efficacy against acute myeloid leukaemia of SH1573, a novel mutant IDH2 inhibitor approved for clinical trials in China显示文摘Acute myeloid leukaemia(AML) is the most common form of acute leukaemia in adults,with increasing incidence with age and a generally poor prognosis.Almost 20% of AML patients express mutant isocitrate dehydrogenase 2(mIDH2),which leads to the accumulation of the carcinogenic metabolite 2-hydroxyglutarate(2-HG),resulting in poor prognosis.Thus,global institutions have been working to develop mIDH2 inhibitors.SH1573 is a novel mIDH2 inhibitor that we independently designed and synthesised.We have conducted a comprehensive study on its pharmacodynamics,pharmacokinetics and safety.First,SH1573 exhibited a strong selective inhibition of mIDH2 R140 Q protein,which could effectively reduce the production of 2-HG in cell lines,serum and tumors of an animal model.It could also promote the differentiation of mutant AML cell lines and granulocytes in PDX models.Then,it was confirmed that SH1573 possessed characteristics of high bioavailability,good metabolic stability and wide tissue distribution.Finally,toxicological data showed that SH1573 had no effects on the respiratory system,cardiovascular system and nervous system,and was genetically safe.This research successfully promoted the approval of SH1573 for clinical trials(CTR20200247).All experiments demonstrated that,as a potential drug against mIDH2 R140 Q acute myeloid leukaemia,SH1573 was effective and safe. | Zhiqiang Wang Zhibo Zhang Yong Li Li Sun Dezhen Peng Danyu Du Xian Zhang Luwei Han Liwen Zhao Ligong Lu Hongzhi Du Shengtao Yuan Meixiao Zhan | 2021 | Acta Pharmaceutica Sinica B2021，11，6： | 3 |
| 6 | Choroidal thickness and choriocapillaris vascular density in myopic anisometropia显示文摘Background:This study aims to examine interocular differences in the choroidal thickness and vascular density of the choriocapillaris in anisometropic myopes and to further explore the relationship between choroidal blood flow and myopia.Methods:The sample comprised 44 participants with anisometropic myopia,aged 9 to 18 years,with normal bestcorrected visual acuity.All participants underwent a series of examinations,including spherical equivalent refraction(SER)and axial length(AL),measured by a Lenstar optical biometer and optical coherence tomography angiography(OCTA)scanner.OCT measured the choroidal thickness,vascular density,and flow voids of the choriocapillaris,and a customized algorithm was implemented in MATLAB R2017a with the post-correction of AL.The choroidal thickness was measured at the fovea and 0.5,1.0,1.5,2.0,2.5,and 3.0 mm nasally,temporally,inferiorly,and superiorly to the fovea.The vascular density and the flow voids of the choriocapillaris were measured at a 0.6-mm-diameter central circle,and the 0.6-2.5 mm diameter circle in the nasal,temporal,inferior,and superior regions.Repeated-measured ANOVAs were used to analyze the interocular differences.Partial correlations with the K value and age adjustments were used to study the relationships between the choroidal thickness,the choriocapillaris vascular density and flow voids,the SER and AL.Results:The choroidal thickness of the more myopic eyes was significantly thinner than less myopic eyes(P≤0.001),and the flow voids in the more myopic eyes were more than less myopic eyes(P=0.002).There was no significant difference in the vascular density of the choriocapillaris between the more and less myopic eyes(P=0.525).However,when anisometropia was more than 1.50 D,the vascular density of choriocapillaris in the more myopic eyes was significantly less than the less myopic eyes(P=0.026).The interocular difference of the choroidal thickness was significantly correlated with the interocular difference in SER and AL in the center,superior,and inferior regions but not in the nasal or temporal regions.The interocular differences of the vascular density and the flow voids of the choriocapillaris were not correlated with the interocular difference of SER and AL.Conclusions:The choroidal thickness is thinner in the more myopic eyes.The flow void is increased,and the vascular density of the choriocapillaris is reduced in the more myopic eyes of children with anisometropia exceeding 1.50 D. | Xinting Liu Zhiyi Lin Feifu Wang Xiaoyi Peng Wenwen He Dan Chen Meixiao Shen Fan Lu Jun Jiang | 2021 | Eye and Vision2021，8，1： | 3 |
| 7 | Photosensitizer conjugate-functionalized poly(hexamethylene guanidine) for potentiated broad-spectrum bacterial inhibition and enhanced biocompatibility显示文摘Pathogen infection is the main cause of human morbidity and death.Traditional antibiotics usually sterilize bacteria in chemical ways,which tends to develop serious antibiotic resistance.Cationic polymers exhibit good bacterial inhibition with less resistance,but often face severe cytotoxicity toward normal cells.The optimization of polymeric antimicrobials for enhanced bactericidal capacity and improved biocompatibility is quite meaningful.In addition,photodynamic therapy(PDT) is a therapeutic modality with less susceptibility to develop resistance.Herein,a typical commercial polymeric antimicrobial,polyhexamethylene guanidine(PHMG) was selected for current proof-of-concept optimization due to its excellent bactericidal capacity but moderate biocompatibility.Eosin-Y(EoS)was copolymerized to afford EoS-labeled polymer conjugates,poly(2-(dimethylamino) ethyl methacrylate-co-eosin),P(DMAEMA-co-EoS),which was conjugated with PHMG to afford a novel polymeric antimicrobial,P(DMAEMA-co-EoS)-b-PHMG-b-P(DMAEMA-co-EoS),noted as PEoS-PHMG.It could efficiently kill broad-spectrum bacteria by physical damage and photodynamic therapy.Compared with PHMG,the bacterial inhibition of PEoS-PHMG was potentiated after the functionalization.Furthermore,PEoS-PHMG exhibited low cytotoxicity and minimal hemolysis,which was demonstrated by cell viability assays toward LO2 cells and RAW 264.7 cells as well as hemolytic assays against red blood cells.These results confirmed that the resultant PEoS-PHMG could act as promising alternative antibacterial materials with excellent broad-spectrum bacterial inhibition and favorable biocompatibility. | Fengfeng Xiao Bing Cao Liewei Wen Yanhong Su Meixiao Zhan Ligong Lu Xianglong Hu | 2020 | Chinese Chemical Letters2020，31，9： | 2 |
| 8 | Associated risk factors in the early stage of diabetic retinopathy显示文摘Background:To investigate the retinal capillary density(RCD)of the macula using optical coherence tomography angiography(OCT-A)in type 2 diabetic patients and to further determine the association with risk factors.Methods:A total of 212 eyes from 212 subjects were recruited;subjects included diabetics with no retinopathy(NDR,n=90 eyes),diabetics with mild retinopathy DR(MDR,n=36 eyes),and healthy participants(Control,n=86 eyes).All participants underwent OCT-A scanning.RCD was quantified by superficial and deep retinal capillary layers(SRCL and DRCL)from OCT-A images.Results:RCD in SRCL and DRCL was lower in NDR(P<0.001)as well as in MDR(P<0.001)when compared with control eyes.Diabetic patients were subdivided according to individual risk factors,complications related to diabetes,and hyperglycemia.Diabetic patients showed lower RCD in both the SRCL and DRCL when compared with healthy controls.Diabetics with age>55y,HbA1c>7%had significantly reduced DRCL(P<0.05)when compared with the other group of diabetics(age<55y,HbA1c<7%).Diabetics with a blood urea nitrogen(BUN)>8.2 mmol/L had significantly reduced SRCL and DRCL when compared to the other group of diabetics.Conclusions:Risk factors including older age,higher level of HbA1c,LDL-C and BUN,were associated with lower RCDs found in type 2 diabetic patients with and without mild DR by OCT-A.The impairment of retinal capillary by OCT-A may play a key role in the early monitoring of management in diabetes. | Fan Tan Qi Chen Xiran Zhuang Chaoming Wu Yanying Qian Yuanyuan Wang Jianhua Wang Fan Lu Meixiao Shen Yingzi Li | 2019 | Eye and Vision2019，6，1： | 2 |

| 17 | Computer-aided diagnosis of retinopathy based on vision transformer显示文摘Age-related Macular Degeneration(AMD)and Diabetic Macular Edema(DME)are two com-mon retinal diseases for elder people that may ultimately cause irreversible blindness.Timely and accurate diagnosis is essential for the treatment of these diseases.In recent years,computer-aided diagnosis(CAD)has been deeply investigated and effectively used for rapid and early diagnosis.In this paper,we proposed a method of CAD using vision transformer to analyze optical co-herence tomography(OCT)images and to automatically discriminate AMD,DME,and normal eyes.A classification accuracy of 99.69%was achieved.After the model pruning,the recognition time reached 0.010 s and the classification accuracy did not drop.Compared with the Con-volutional Neural Network(CNN)image classification models(VGG16,Resnet50,Densenet121,and EfficientNet),vision transformer after pruning exhibited better recognition ability.Results show that vision transformer is an improved alternative to diagnose retinal diseases more accurately. | Zhencun Jiang Lingyang Wang Qixin Wu Yilei Shao Meixiao Shen Wenping Jiang Cuixia Dai | 2022 | Journal of Innovative Optical Health Sciences2022，15，2： | 1 |

| 19 | High drug loading and pH-responsive nanomedicines driven by dynamic boronate covalent chemistry for potent cancer immunotherapy显示文摘Tumor cells undergoing immunogenic cell death (ICD) have emerged as an in situ therapeutic vaccine helping to activate a persistent anti-tumor response. Several chemotherapeutic agents have been demonstrated to induce ICD, however accompanied with severe adverse effects in the clinic, weakening its immune responses. Herein, to elicit an intensive ICD while minimizing the systemic toxicity, we introduce a tumor targeting peptide modified bortezomib (BTZ) loading nanomedicine (i-NPBTZ) for the efficient delivery and controlled release of BTZ in tumors. This system is constructed by conjugating BTZ to PEGylated polyphenols via a pH-sensitive covalent boronate-phenol bond that allows them to self-assemble into nanovesicles in neutral condition with high drug loading efficiency. Once accumulated in acidic environment, BTZ-phenolic network is disassembled and thereby accelerates the release of BTZ from nanocarriers. The released BTZ selectively kill tumor cells with a concomitant evocation of tumor-specific cytotoxic T cells by triggering ICD in vivo. This can finally lead to an extended tumor ablation and prevention of distant metastasis in a syngeneic tumor mouse model, while reducing the systemic toxicity of BTZ. In general, our system offers a novel concept with clinical potential to exploit ICD for potentiating tumor immunotherapy and also provides an excellent example of the application of polymer-drug interaction for efficient drug delivery and controllable release. | Wei Jiang Han Zhou Qin Wang Ziqi Chen Wang Dong Zixuan Guo Yong Li Wei Zhao Meixiao Zhan Yucai Wang Ligong Lu | 2021 | Nano Research2021，14，11： | 1 |
