| 1 | Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children. | Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team | 2020 | Neuroscience Bulletin2020,36,9: | 158 |
| 2 | Corrosion Behavior of Mg-Zn-Y Alloy with Long-period Stacking Ordered Structures显示文摘Mg-Zn-Y alloys with long-period stacking ordered structures were prepared by an ingot casting method. The corrosion performance of Mg-Zn-Y alloys was studied by combining gas-collecting test, immersion test and electrochemical measurements in order to determine the corrosion rate and mechanism of the alloys. The results showed that the volume fraction of Mg(12)YZn phase increased and the shape of the Mg(12)YZn phase changed from discontinuous to continuous net-like with increasing Zn and Y content. The corrosion rate of the alloys greatly depended on the distribution and volume fraction of the Mg(12)YZn phase. Corrosion products appeared at the junction of Mg phase and Mg(12)YZn phase, indicating that the Mg(12)YZn phase accelerated galvanic corrosion of Mg matrix. Mg(97)Zn1Y2 alloy shows the lowest corrosion rate due to the continuous distribution of Mg(12)YZn phase. | Jinshan Zhang Jidong Xu Weili Cheng Changjiu Chen Jingjing Kang | 2012 | Journal of Materials Science & Technology2012,28,12: | 17 |
| 3 | Beclin 1 cleavage by caspase-3 inactivates autophagy and promotes apoptosis显示文摘Autophagy and apoptosis are both highly regulated biological processes that play essential roles in tissue homeostasis,development and diseases.Autophagy is also described as a mechanism of death pathways,however,the precise mechanism of how autophagy links to cell death remains to be fully understood.Beclin 1 is a dual regulator for both autophagy and apoptosis.In this study we found that Beclin 1 was a substrate of caspase-3 with two cleavage sites at positions 124 and 149,respectively.Furthermore,the autophagosome formation occurred,followed by the appearance of morphological hallmarks of apoptosis after staurosporine treatment.The cleavage products of Beclin 1 reduced autophagy and promoted apoptosis in HeLa cells and the cells in which Beclin 1 was stably knocked down by specific shRNA.In addition,the cleavage of Beclin 1 resulted in abrogating the interaction between Bcl-2 with Beclin 1,which could be blocked by z-VAD-fmk.Thus,our results suggest that the cleavage of Beclin 1 by caspase-3 may contribute to inactivate autophagy leading towards augmented apoptosis. | Yushan Zhu Lixia Zhao Lei Liu Ping Gao Weili Tian Xiaohui Wang Haijing Jin Haidong Xu Quan Chen | 2010 | Protein & Cell2010,1,5: | 17 |
| 4 | CRISPR/Cas9-mediated PINK1 deletion leads to neurodegeneration in rhesus monkeys显示文摘Dear Editor,PINK1 mutations cause autosomal recessive and early-onset Parkinson’s disease(PD)with selective neurodegeneration.Unfortunately,current PINK1 knockout(KO)mouse1,2 and pig models3,4 are unable to recapitulate the selective and overt neurodegeneration seen in PD patients.Furthermore,endogenous Pink1 in the mouse brain is expressed at very low levels and can only be detected via immunoprecipitation,5 meaning that PINK1’s function in the mammalian brain needs to be assessed using larger animals that are closer to humans.We previously used CRISPR/Cas9 to target the monkey gene in one-cell stage embryos.6 Using the same approach,we designed two gRNAs to target exon 2(T1)and exon 4(T2),which encode a kinase domain in the PINK1 gene of rhesus monkeys(Fig.1a).CRISPR/Cas9 and PINK1 gRNAs were injected into one-cell stage rhesus monkey embryos.A T7E1 assay and sequencing of PCR products from the injected embryos showed high efficiency(61.5%)in targeting PINK1(Fig.1b and Supplementary information,Fig.S1).Transfer of 87 embryos to 28 surrogate rhesus monkeys resulted in 11 pregnancies(39.2%)(Fig.1b).Eleven fetuses developed to term and were born naturally.Of these live monkeys,eight carried PINK1 mutations(M),and three were wild type(WT).However,three mutant monkeys(M1,M3 and M4)were newborn triplets that struggled to survive and died 3-4 days after birth.One WT newborn monkey also died after a difficult labor.Another mutant monkey(M2)died 7 days after birth without noticeable warning signs or symptoms.The other three mutant monkeys(M6,M7 and M8)have lived for three years;M5,however,reduced its food intake and showed weakness at the age of 1.5 years,and died 30 days after anesthesia for MRI examination. | Weili Yang Yunbo Liu Zhuchi Tu Chong Xiao Sen Yan Xishan Ma Xiangyu Guo Xiusheng Chen Peng Yin Zhengyi Yang Su Yang Tianzi Jiang Shihua Li Chuan Qin Xiao-Jiang Li | 2019 | Cell Research2019,29,4: | 12 |
| 5 | Outcomes in refractory diffuse large B-cell lymphoma:results fromamulticenter real-world study in China显示文摘Background:Diffuse large B-cell lymphoma(DLBCL)patients refractory to rituximab-based immunochemotherapy have a dismal prognosis.However,the definition of refractory DLBCL remains inconsistent and no large cohort study data is available from Asian countries.To validate the definition and outcomes of refractory DLBCL in China,we conducted a multicenter,retrospective cohort study.Methods:The REtrospective AnaLysis of Treatment REspoNse of refractory DLBCL(REAL-TREND)study was performed using real-world data from 8 centers in China.DLBCL patients with curative intent were included in the REAL-TREND dataset.Overall survival(OS)was estimated using the Kaplan-Meier method and compared by the log-rank test.Due to heterogeneity in response rates among different centers,the response rates of refractory patients were pooled using random-effect models.Multivariate survival analysis was performed using the Cox regression model.Results:A total of 2778 DLBCL patients diagnosed between January,2010 and December,2015 were enrolled to this study.After validating previous definitions,the SCHOLAR-1 study was most suitable to define refractory DLBCL.The estimated 5-year cumulative incidence of refractory patients was 20%(95% confidence Interval[CI]=18%-22%).After the determination of refractory disease,overall response rate and complete remission rate were 30%(95%CI=22%-38%)and 9%(95%CI=4%-15%),respectively.Patients with either no response to immunochemotherapy or relapse within 12 months after stem-cell transplantation had inferior survival with a median OS of 5.9 months(95%CI=5.5-7.1 months)and 2-year OS rate of 16%(95%CI=12%-20%).International prognostic index score 4-5(hazard ratio[HR]=2.22;95%CI=1.47-3.35),central nervous systemrelapse(HR=1.43;95%CI=1.04-1.97),and best response status(HR=2.68;95%CI=1.42-5.03 for partial remission.HR=5.97,95%CI=3.21-11.11 for stable disease/progressive disease)were independent unfavorable prognostic factors.Conclusions:This is the first large-scale Asian cohort study focusing on outcomes of refractory DLBCL.The definition of the SCHOLAR-1 study identifies patients with homogenously inferior survival,thus is appropriate to select refractory DLBCL.Due to poor clinical outcomes in the rituximab era,patients with refractory DLBCL may be potential candidates for novel treatment modalities. | Shuo Wang Li Wang Jianda Hu Wenbin Qian Xi Zhang Yu Hu Qi Zhu Bobin Chen Depei Wu Chung-Chou H.Chang Pengpeng Xu Xiaoyun Zheng Juying Wei Yao Liu Guohui Cui Yong Tang Yan Ma Haiwen Huang Hongmei Yi Weili Zhao | 2021 | Cancer Communications2021,41,3: | 10 |

| 7 | Smartphone-Imaged HIV-1 Reverse-Transcription Loop-Mediated Isothermal Ampliflcation(RT-LAMP) on a Chip from Whole Blood显示文摘Viral load measurements are an essential tool for the long-term clinical care of hum an immunodeficiency virus(HIV)-positive individuals. The gol d standards in viral load instrumentation, however, are still too limited by their size, cost, and sophisticated operation for these measurements to be ubiquitous in remote settings with poor healthcare infrastructure, including parts of the world that are disproportionately affected by HIV infection. The challenge of developing a point-of-care platform capable of making viral load more accessible has been frequently approached but no solution has yet emerged that meets the practical requirements of low cost, portability, and ease-of-use. In this paper, we perform reverse-transcription loop-mediated isothermal amplification(RT-LAMP) on minimally processed HIV-spiked whole blood samples with a microfluidic and silicon microchip platform, and perform fluorescence measurements with a consumer smartphone. Our integrated assay shows amplification from as few as three viruses in a ~ 60 nL RTLAMP droplet, corresponding to a whole blood concentration of 670 viruses per μL of whole blood. The technology contains greater power in a digital RT-LAMP approach that could be scaled up for the determination of viral load from a flnger prick of blood in the clinical care of HIV-positive individuals. We demonstrate that all aspects of this viral load approach, from a drop of blood to imaging the RT-LAMP reaction, are compatible with lab-on-a-chip components and mobile instrumentation. | Gregory L.Damhorst Carlos Duarte-Guevara Weili Chen Tanmay Ghonge Brian T.Cunningham Rashid Bashir | 2015 | Engineering2015,1,3: | 8 |
| 8 | Degradation of 4-nitrophenol by electrocatalysis and advanced oxidation processes using Co3O4@C anode coupled with simultaneous CO2 reduction via SnO2/CC cathode显示文摘Herein,we prepa red novel three-dimensional(3D)gear-s haped Co3O4@C(Co3O4 modified by amorphous carbon)and sheet-like SnO2/CC(SnO2 grow on the carbon cloth)as anode and cathode to achieve efficient removal of 4-nitrophenol(4-NP)in the presence of peroxymonosulfate(PMS)and simultaneous electrocatalytic reduction of CO2,respectively.In this process,4-NP was mineralized into CO2 by the Co3O4@C,and the generated CO2 was reduced into HCOOH by the sheet-like SnO2/CC cathode.Compared with the pure Co0.5(Co3O4 was prepared using 0.5 g urea)with PMS(30 mg,0.5 g/L),the degradation efficiency of 4-NP(60 mL,10 mg/L)increased from 74.5%-85.1%in 60 min using the Co0.5 modified by amorphous carbon(Co0.5@C).Furthermore,when the voltage of 1.0 V was added in the anodic system of Co0.5@C with PMS(30 mg,0.5 g/L),the degradation efficiency of 4-NP increased from 85.1%-99.1%when Pt was used as cathode.In the experiments of 4-NP degradation coupled with simultaneous electrocatalytic CO2 reduction,the degradation efficiency of 4-NP was 99.0%in the anodic system of Co0.5@C with addition of PMS(30 mg,0.5 g/L),while the Faraday efficiency(FE)of HCOOH was 24.1%at voltage of-1.3 V using the SnO2/CC as cathode.The results showed that the anode of Co3O4 modified by amorphous carbon can markedly improve the degradation efficiency of 4-NP,while the cathode of SnO2/CC can greatly improve the FE and selectivity of CO2 reduction to HCOOH and the stability of cathode.Finally,the promotion mechanism was proposed to explain the degradation of organic pollutants and reduction of CO2 into HCOOH in the process of electrocatalysis coupled with advanced oxidation processes(AOPs)and simultaneous CO2 reduction. | Meng Zhu Longshuai Zhang Shanshan Liu Dengke Wang Yuancheng Qin Ying Chen Weili Dai Yuehua Wang Qiuju Xing Jianping Zou | 2020 | Chinese Chemical Letters2020,31,7: | 7 |
| 9 | Sedimentation Rate Rhythms:Evidence from Filling of the Tarim Basin,Northwest China显示文摘Variations of sedimentation rate within a basin over geologic time are a time series that can be filtered into several cyclic wave curves. Based on back-stripping and the empirical mode decomposition method, the cores from 14 wells in the Tarim Basin were selected to do filtering analysis. Four cycles or quasi-cycles(33 Ma, 64.4 Ma, 103.6 Ma, and 224 Ma) were obtained. Among these, the 33 Ma period, which was related to the internal earth activity, an external force, or a combination of the two, was the most obvious. The 64.4 Ma period corresponded to the solar system crossing the galaxy plane or the periodic melting of inner-earth material. The 103.6 Ma period was related with plate collisional tectonism around the Tarim Plate. The 224 Ma period was related to one galaxy year and may also be related to the aesthenospherical convection cycle. | CHEN Shuping JIN Zhijun WANG Yi ZHOU Ziyong LI Jingchang YANG Weili | 2015 | Acta Geologica Sinica(English Edition)2015,89,4: | 6 |
| 10 | Clinical effectiveness of cognitive behavioural therapy on alcoholdependent patients:an observation with the WeChat platform显示文摘Background With the continuous improvement of people's material living standards,the consumption of alcoholic beverages is increasing.Alcohol dependence caused by alcohol addiction has become a widespread concern in society.As the brand-new medical and health model created by the modern biomedical technology revolution and the information technology revolution,mobile health has been used more and more widely in the field of medical health with the characteristics of convenience,rapidity and generalisability.With the general use of the social software WeChat,it is feasible to implement mobile health on the WeChat platform.Aim We aimed to explore the clinical effect of WeChat platform used in the cognitive behavioural therapy(CBT)on the maintenance period of alcohol dependence and addiction.Methods Seventy alcohol-dependent patients in the withdrawal maintenance stage admitted into our hospital were randomly divided into the CBT on WeChat platform group(the experiment group,n=35)and the general clinical treatment using sertraline group(the control group,n=35)with block randomisation grouping.They were evaluated with the Severity of Alcohol Dependence Questionnaire(SADQ-C)before the treatment,at the end of the fourth week,at the end of the eighth week and at the end of the twelfth week of treatment.In addition,Zung's Self-Rating Anxiety Scale(SAS)and Self-Rating Depression Scale(SDS)were employed to evaluate the degree of anxiety and depression of the two groups.Results The SADQ-C,SAS and SDS scores of the two groups after treatment decreased markedly compared with those before treatments,and the differences were statistically significant.Between-group comparison:the SADQ-C scores of the experiment group at the end of the fourth,eighth and twelfth weeks were lower than those of the control group,and the difference was statistically significant,which indicated that the score reduction in the experiment group was larger than that in the control group.The SAS and SDS scores of the experiment group at these time points were not significantly different from those of the control group,which indicated that these two treatment methods were comparable in treating patients1 anxiety and depression.Conclusion The CBT in tervention using WeChat may improve the subjectively reported severity of alcohol dependence of patients who had completed detoxification.It is conducive to prevention of relapse,and is convenient for patients.It is worthy of clinical application and further study. | Jing Chen Mincai Qian Conghao Sun Min Lin Weili fang | 2019 | General Psychiatry2019,32,5: | 6 |

| 14 | Effectiveness of ZiYin Xiehuo granules and Zishen Qinggan granules on partial precocious puberty in girls: a multicenter, randomized, single-blind, controlled trial显示文摘OBJECTIVE: To evaluate the effect of ZiYin Xiehuo granules(ZYXH) and Zishen Qinggan granules(ZSQG) on partial precocious puberty(PPP).METHODS: This was a multicenter, randomized, single-blind, positive-controlled trial. A total of 143 pa-tients were assigned to either the ZYXH group or the ZSQG group using a random number table. The ZYXH group received ZYXH three times daily for 6 months and the ZSQG group received ZSQG three times daily for 6 months. Mammary nucleus diameter; the results of uterus, ovarian, and maximum follicle measures; and Chinese medicine symptom pattern scores were compared at baseline and after 3 months and 6 months of treatment.RESULTS: After 3 months' treatment, there were no significant differences between the two groups in mammary nucleus index changes(left 3.4 ± 3.1 vs3.5 ± 3.1, P = 0.790; right 3.0 ± 2.9 vs 3.6 ± 3.0, P =0.719). The uterine volume in the ZYXH group was smaller than that in the ZSQG group(2.1 ± 1.6 vs2.6 ± 2.2, P = 0.006). There were no significant between-group differences in ovarian volume and maximum follicular diameter on either side(ovarian volume: left 1.2 ± 0.7 vs 1.3 ± 0.6, P = 0.8; right1.2 ± 0.7 vs 1.4 ± 1.1, P = 0.984; maximum follicular diameter: left 3.9 ± 1.7 vs 3.5 ± 2.2, P = 0.158; right3.5 ± 1.7 vs 3.9 ± 2.1, P = 0.314).CONCLUSION: ZYXH granules and ZSQG granules both affected the size of the mammary nucleus in girls with PPP, and improved Chinese medicine symptom patterns. ZYXH granules showed slight advantages over ZSQG granules in terms of the decrease in the size of the uterus, ovaries, and ovarian follicles. | Sun Wen Han Xinghui Wang Yonghong Yu Jian Yan Weili Zhao Jun Chen Weibin Xue Zheng | 2018 | Journal of Traditional Chinese Medicine2018,38,5: | 5 |
| 15 | Cryo-self-assembled silk fibroin sponge as a biodegradable platform for enzyme-responsive delivery of exosomes显示文摘Although advances in protein assembly preparation have provided a new platform for drug delivery during tissue engineering,achieving long-term controlled exosome delivery remains a significant challenge.Diffusion-dominated exosome release using protein hydrogels results in burst release of exosomes.Here,a fibroin-based cryo-sponge was developed to provide controlled exosome release.Fibroin chains can self-assemble into silk I structures under ice-cold conditions when annealed above the glass transition temperature.Exosome release is enzyme-responsive,with rates primarily determined by enzymatic degradation of the scaffolds.In vivo experiments have demonstrated that exosomes remain in undigested sponge material for two months,superior to their retention in fibrin glue,a commonly used biomaterial in clinical practice.Fibroin cryo-sponges were implanted subcutaneously in nude mice.The exosome-containing sponge group exhibited better neovascularization and tissue ingrowth effects,demonstrating the efficacy of this exosome-encapsulating strategy by realizing sustained release and maintaining exosome bioactivity.These silk fibroin cryo-sponges containing exosomes provide a new platform for future studies of exosome therapy. | Muyang Sun Qi Li Huilei Yu Jin Cheng Nier Wu Weili Shi Fengyuan Zhao Zhenxing Shao Qingyang Meng Haifeng Chen Xiaoqing Hu Yingfang Ao | 2022 | Bioactive Materials2022,7,2: | 4 |

| 17 | Time-domain terahertz optoacoustics: manipulable water sensing and dampening显示文摘Radiation at terahertz frequencies can be used to analyze the structural dynamics of water and biomolecules,but applying the technique to aqueous solutions and tissues remains challenging since terahertz radiation is strongly absorbed by water.While this absorption enables certain analyses,such as the structure of water and its interactions with biological solutes,it limits the thickness of samples that can be analyzed,and it drowns out weaker signals from biomolecules of interest.We present a method for analyzing water-rich samples via time-domain terahertz optoacoustics over a 104-fold thickness ranging from microns to centimeters.We demonstrate that adjusting the temperature to alter the terahertz optoacoustic(THz-OA)signal of water improves the sensitivity with which it can be analyzed and,conversely,can reduce or even“silence”its signal.Temperature-manipulated THz-OA signals of aqueous solutions allow detection of solutes such as ions with an order of magnitude greater sensitivity than terahertz time-domain spectroscopy,and potentially provide more characteristic parameters related to both terahertz absorption and ultrasonic propagation.Terahertz optoacoustics may be a powerful tool for spectroscopy and potential imaging of aqueous solutions and tissues to explore molecular interactions and biochemical processes. | Jiao Li Yixin Yao Liwen Jiang Shuai Li Zhihao Yi Xieyu Chen Zhen Tian Weili Zhang | 2021 | Advanced Photonics2021,3,2: | 4 |
| 18 | Mechanism and effect of Shijueming (Concha Haliotidis) on serum calcium in spontaneously hypertensive rats显示文摘OBJECTIVE: To observe the impact of Shijueming (Concha Haliotidis) on spontaneously hypertensive rats via blood pressure, serum calcium, vascular smooth muscle membrane L-type calcium channel α1 C subunit (CaL-α1C), plasma membrane calcium-ATPase (PMCA) mRNA expression, and the L-type calcium channel in vascular smooth muscle cells. METHODS:Twelve-week-old male rats with spontaneous hypertension were divided into three groups: a Shijueming (Concha Haliotidis) group (group 1), a nifedipine group (group 2), and a distilled water group (group 3). All were given a four-week treatment. Blood pressure and dissociative serum calcium were examined before treatment. Blood pressure was taken every week during treatment. Atomic absorption spectrometry was used to examine dissociative serum calcium. Re-verse transcription-polymerase chain reaction was used to examine the expression of CaL-α1C and PM-CA1 mRNA. The patch clamp technique was used to examine the electrophysiological characteristics of the vascular smooth muscle cell calcium channels. RESULTS: After treatment, blood pressure of the Shijueming (Concha Haliotidis) group lowered but not significantly (P>0.05). Blood pressure of the nifedipine group lowered significantly (P<0.05). Blood pressure of the distilled water group remained high. The concentration of serum calcium in the Shijueming (Concha Haliotidis) and the distilled water groups lowered (P<0.05). Expression of CaL-α1C mRNA in the nifedipine group decreased compared with the distilled water group (P<0.01). There was the decreasing trend in the Shijueming (Concha Haliotidis) group, but it was not statistically significant. Shijueming (Concha Haliotidis) also had effects on the expression of PMCA1 mRNA but with- out statistical significance. However, there was a significant decreasing effect on vascular smooth muscle cell I Ca-L flow. CONCLUSION: This study indicated that Shijueming (Concha Haliotidis) could increase serum calcium and decrease blood pressure. It may work by influencing calcium channels, expression of PMCA1 mRNA, and regulating ion calcium channels and calcium-ATPase. | Chao Chen Changlin Zhao Xuejun Wang Weili Li Xiaoyin Chen | 2013 | Journal of Traditional Chinese Medicine2013,33,3: | 4 |
| 19 | Effects of Ti addition on the microstructure and mechanical properties of Mg-Zn-Zr-Ca alloys显示文摘The effects of Ti additions(0,0.4,0.6,0.8,1.0,1.2 wt.%)on the microstructure and mechanical properties of as-cast and aging Mg-0.4%Zn-1.0%Zr-1.5%Ca(wt.%)alloys were investigated.The results indicated that minor Ti can effectively refine grains,while excessive Ti addition resulted in the grain coarsening.When the content of Ti was 0.8 wt.%,the as-cast alloy exhibited the finest grain size of 39μm which contributed to the optimal mechanical properties with Brinell hardness of 57.9 HB,ultimate tensile strength of 145 MPa and elongation of 3.2%.After T6 heat treatment,the continuous net-like Mg_(2)Ca and Mg_(6)Zn_(3)Ca_(2)phases changed to uniform massive T phases(ternary Mg-Zn-Ca phases)and dispersive halo-like precipitates(Mg_(2)Ca and Mg_(6)Zn_(3)Ca_(2)phases).The ultimate tensile strengths of the alloy at room temperature(RT),175℃and 200℃were correspondingly improved to 182 MPa,169 MPa and 141 MPa,respectively. | Jingai Chen Yan Sun Jinshan Zhang Weili Cheng Xiaofeng Niu Chunxiang Xu | 2015 | Journal of Magnesium and Alloys2015,3,2: | 4 |
| 20 | Permeation into but not across the cornea:Bioimaging of intact nanoemulsions and nanosuspensions using aggregation-caused quenching probes显示文摘Nanoemulsions(NEs) and nanosuspensions(NSs) show great potential in enhancing the ocular bioavailability of therapeutics through topical delivery. However, transocular fate of intact NEs and NSs is still inconclusive. In this study, an aggregation-caused quenching fluorescent probe is used to track precorneal retention and transocular transportation of intact NEs and NSs, while coumarin 6 is used to mimick the cargo. NEs show superior precorneal retention to NSs. Both the two types of nanocarriers can permeate into but not across the cornea. The smaller NEs(100 nm) permeate better into the cornea than the bigger ones(210 nm). Nanocarriers in the cornea serves as depots. The released cargo molecules can penetrate across the cornea and diffuse into the lens. Moreover, the conjunctiva-scleral route may be potential to deliver drugs to the back of the eye, In conclusion, the study provides useful tools and information in the field of transocular transportation of nanoparticles. | Dailei Liu Bo Wan Jianping Qi Xiaochun Dong Weili Zhao Wei Wu Yikang Dai Yi Lu Zhongjian Chen | 2018 | Chinese Chemical Letters2018,29,12: | 4 |
