| 1 | Synergistic effect of fluorination on both donor and acceptor materials for high performance non-fullerene polymer solar cells with 13.5% efficiency显示文摘A high performance polymer solar cells(PSCs) based on polymer donor PM6 containing fluorinated thienyl benzodithiophene unit and n-type organic semiconductor acceptor IT-4 F containing fluorinated end-groups were developed. In addition to complementary absorption spectra(300–830 nm) with IT-4 F, the PM6 also has a deep HOMO(the highest occupied molecular) level(-5.50 e V), which will lower the open-circuit voltage(V_(oc)) sacrifice and reduce the E_(loss) of the IT-4 F-based PSCs. Moreover, the strong crystallinity of PM6 is beneficial to form favorable blend morphology and hence to suppress recombination. As a result, in comparison with the PSCs based on a non-fluorinated D/A pair of PBDB-T:ITIC with a medium PCE of 11.2%, the PM6:IT-4 Fbased PSCs yielded an impressive PCE of 13.5% due to the synergistic effect of fluorination on both donor and acceptor, which is among the highest values recorded in the literatures for PSCs to date. Furthermore, a PCE of 12.2% was remained with the active layer thickness of up to 285 nm and a high PCE of 11.4% was also obtained with a large device area of 1 cm^2. In addition, the devices also showed good storage, thermal and illumination stabilities with respect to the efficiency. These results indicate that fluorination is an effective strategy to improve the photovoltaic performance of materials, as well as the both fluorinated donor and acceptor pair-PM6:IT-4 F is an ideal candidate for the large scale roll-to-roll production of efficient PSCs in the future. | Qunping Fan Wenyan Su Yan Wang Bing Guo Yufeng Jiang Xia Guo Feng Liu Thomas P.Russell Maojie Zhang Yongfang Li | 2018 | Science China Chemistry2018，61，5： | 18 |
| 2 | Research status of biodegradable metals designed for oral and maxillofacial applications:A review显示文摘The oral and maxillofacial regions have complex anatomical structures and different tissue types,which have vital health and aesthetic functions.Biodegradable metals(BMs)is a promising bioactive materials to treat oral and maxillofacial diseases.This review summarizes the research status and future research directions of BMs for oral and maxillofacial applications.Mg-based BMs and Zn-based BMs for bone fracture fixation systems,and guided bone regeneration(GBR)membranes,are discussed in detail.Zn-based BMs with a moderate degradation rate and superior mechanical properties for GBR membranes show great potential for clinical translation.Fe-based BMs have a relatively low degradation rate and insoluble degradation products,which greatly limit their application and clinical translation.Furthermore,we proposed potential future research directions for BMs in the oral and maxillofacial regions,including 3D printed BM bone scaffolds,surface modification for BMs GBR membranes,and BMs containing hydrogels for cartilage regeneration,soft tissue regeneration,and nerve regeneration.Taken together,the progress made in the development of BMs in oral and maxillofacial regions has laid a foundation for further clinical translation. | Dandan Xia Fan Yang Yufeng Zheng Yunsong Liu Yongsheng Zhou | 2021 | Bioactive Materials2021，6，11： | 9 |
| 3 | Three-dimensional-printed individualized porous implants:A new“implant-bone”interface fusion concept for large bone defect treatment显示文摘Bone defect repairs are based on bone graft fusion or replacement.Current large bone defect treatments are inadequate and lack of reliable technology.Therefore,we aimed to investigate a simple technique using three-dimensional(3D)-printed individualized porous implants without any bone grafts,osteoinductive agents,or surface biofunctionalization to treat large bone defects,and systematically study its long-term therapeutic effects and osseointegration characteristics.Twenty-six patients with large bone defects caused by tumor,infection,or trauma received treatment with individualized porous implants;among them,three typical cases underwent a detailed study.Additionally,a large segmental femur defect sheep model was used to study the osseointegration characteristics.Immediate and long-term biomechanical stability was achieved,and the animal study revealed that the bone grew into the pores with gradual remodeling,resulting in a long-term mechanically stable implant-bone complex.Advantages of 3D-printed microporous implants for the repair of bone defects included 1)that the stabilization devices were immediately designed and constructed to achieve early postoperative mobility,and 2)that osseointegration between the host bone and implants was achieved without bone grafting.Our osseointegration method,in which the“implant-bone”interface fusion concept was used instead of“bone-bone”fusion,subverts the traditional idea of osseointegration. | Teng Zhang Qingguang Wei Hua Zhou Zehao Jing Xiaoguang Liu Yufeng Zheng Hong Cai Feng Wei Liang Jiang Miao Yu Yan Cheng Daoyang Fan Wenhao Zhou Xinhong Lin Huijie Leng Jian Li Xinyu Li Caimei Wang Yun Tian Zhongjun Liu | 2021 | Bioactive Materials2021，6，11： | 9 |
| 4 | Melatonin enhances radiofrequency-induced NK antitumor immunity,causing cancer metabolism reprogramming and inhibition of multiple pulmonary tumor development显示文摘Surgery is the comm on treatme nt for early lung cancer with multiple pulm onary no dules,but it is often accompanied by the problem of significant malignancy of other nodules in non-therapeutic areas.In this study,we found that a combined treatment of local rad iofreq ue ncy ablati on(RFA)and melatonin(MLT)greatly improved clinical outcomes for early lung cancer patie nts with multiple pulmonary nodules by minimizing lung function injury and reducing the probability of malignant transformation or enlargement of nodules in non-ablated areas.Mechanically,as demonstrated in an associated mouse lung tumor model,RFA not only effectively remove treated tumors but also stimulate antitumor immunity,which could inhibit tumor growth in non-ablated areas.MLT enhanced RFA-stimulated NK activity and exerted synergistic antitumor effects with RFA.Transcriptomics and proteomics analyses of residual tumor tissues revealed enhanced oxidative phosphorylation and reduced acidification as well as hypoxia in the tumor microenvironment,which suggests reprogrammed tumor metabolism after combined treatment with RFA and MLT.Analysis of residual tumor further revealed the depressed activity of MAPK,NF-kappa B,Wnt,and Hedgehog pathways and upregulated P53 pathway in tumors,which was in line with the inhibited tumor growth.Combined RFA and MLT treatment also reversed the Warburg effect and decreased tumor malignancy.These findings thus demonstrated that combined treatment of RFA and MLT effectively inhibited the malignancy of non-ablated nodules and provided an innovative non-invasive strategy for treating early lung tumors with multiple pulmonary nodules.Trial registration:www.chictr.org.cn,identifier ChiCTR2100042695,http://gffzz62a03ee25e6f4a77hubkxouwnccfu6vqv.ffgz.tsg.suse.edu.cn/showproj.aspx?proj=120931. | Ming Li Bingjie Hao Menghuan Zhang Russel J.Reiter Shumeng Lin Tiansheng Zheng Xiangyun Chen Yanbei Ren Liduo Yue Baigenzhin Abay Guojie Chen Xiao Xu Yufeng Shi Lihong Fan | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |
| 5 | In vitro and in vivo degradation behavior of Mg-2Sr-Ca and Mg-2Sr-Zn alloys显示文摘Magnesium alloys with integration of degradability and good mechanical performance are desired for orthopedic implants.In this paper,Mg-2Sr-Ca and Mg-2Sr-Zn alloys were prepared and the degradation as well as the bone response were investigated.Compared with the binary Mg-2Sr alloys,the addition of Ca and Zn improved the in vitro and in vivo corrosion resistance.Mg-2Sr-Ca and Mg-2Sr-Zn alloys exhibited more uniform corrosion and maintained the configuration of the implants 4 weeks post-implantation.The in vivo corrosion rates were 0.85 mm/yr for Mg-2Sr-Zn and 1.10 mm/yr for Mg-2Sr-Ca in comparison with 1.37 mm/yr for Mg-2Sr.The in vitro cell tests indicated that Mg-2Sr-Ca and Mg-2Sr-Zn alloys exhibited higher MG63 cell viability than Mg-2Sr alloy.Furthermore,these two alloys can promote the mineralization and new bone formation without inducing any significant adverse effects and this sound osteogenic properties suggest its attractive clinical potential. | Kai Chen Xinhui Xie Hongyan Tang Hui Sun Ling Qin Yufeng Zheng Xuenan Gu Yubo Fan | 2020 | Bioactive Materials2020，5，2： | 6 |
| 6 | Preparation of 5-fluorouracil-loaded chitosan nanoparticles and study of the sustained release in vitro and in vivo显示文摘The sustained-release properties of the biodegradable nano-drug delivery systems were used to improve the residence time of the chemotherapeutic agent in the body. These drug delivery systems were widely used to deliver chemotherapeutic drugs. The 5-fluorouracil loaded chitosan nanoparticles prepared in this paper have the above advantage. Here, we found that when the mass ratio of 5-fluorouracil and chitosan was 1:1, the maximum drug loading of nanoparticles was 20.13 ± 0.007%, the encapsulation efficiency was 44.28 ± 1.69%, the particle size was 283.9 ± 5.25 nm and the zeta potential was 45.3 ± 3.23 mV. The prepared nanoparticles had both burst-release and sustained-release phases in vitro release studies.In addition, the inhibitory effect of the prepared nanoparticles on gastric cancer SGC-7901 cells was similar to that of 5-fluorouracil injection, and the blank vector had no obvious inhibitory effect on SGC-7901 cells. In the pharmacokinetic study of rats in vivo, we found that AUC(0-t), MRT(0-t) and t1/2 z of nanoparticles were significantly increased in vivo compared with 5-fluorouracil solution, indicating that the prepared nanoparticles can play a role in sustained-release. | Li Sun Yunna Chen Yali Zhou Dongdong Guo Yufan Fan Fangyan Guo Yufeng Zheng Weidong Chen | 2017 | Asian Journal of Pharmaceutical Sciences2017，12，5： | 4 |
| 7 | Repeated febrile convulsions impair hippocampal neurons and cause synaptic damage in immature rats: neuroprotective effect of fructose-1,6-diphosphate显示文摘Fructose-1,6-diphosphate is a metabolic intermediate that promotes cell metabolism. We hypothesize that fructose-1,6-diphosphate can protect against neuronal damage induced by febrile convulsions. Hot-water bathing was used to establish a repetitive febrile convulsion model in rats aged 21 days, equivalent to 3–5 years in humans. Ninety minutes before each seizure induction, rats received an intraperitoneal injection of low- or high-dose fructose-1,6-diphosphate(500 or 1,000 mg/kg, respectively). Low- and high-dose fructose-1,6-diphosphate prolonged the latency and shortened the duration of seizures. Furthermore, high-dose fructose-1,6-diphosphate effectively reduced seizure severity. Transmission electron microscopy revealed that 24 hours after the last seizure, high-dose fructose-1,6-diphosphate reduced mitochondrial swelling, rough endoplasmic reticulum degranulation, Golgi dilation and synaptic cleft size, and increased synaptic active zone length, postsynaptic density thickness, and synaptic interface curvature in the hippocampal CA1 area. The present findings suggest that fructose-1,6-diphosphate is a neuroprotectant against hippocampal neuron and synapse damage induced by repeated febrile convulsion in immature rats. | Jianping Zhou Fan Wang Jun Zhang Hui Gao Yufeng Yang Rongguo Fu | 2014 | Neural Regeneration Research2014，9，9： | 4 |
| 8 | 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 |
| 9 | Ridge-furrow plastic mulching with a suitable planting density enhances rainwater productivity,grain yield and economic benefit of rainfed maize显示文摘Soil surface mulching and planting density regulation are widely used for effective utilization of limited rainwater resources and improvement of crop productivity in dryland farming.However,the combined effects of mulching type and planting density on maize growth and yield have been seldom studied,especially in different hydrological years.A field experiment was conducted to evaluate the effects of mulching type and planting density on the soil temperature,growth,grain yield(GY),water use efficiency(WUE)and economic benefit of rainfed maize in the drylands of northern China during 2015-2017.Precipitation fluctuated over the three years.There were four mulching types(NM,flat cultivation with non-mulching;SM,flat cultivation with straw mulching;RP,plastic-mulched ridge plus bare furrow;RPFS,plastic-mulched ridge plus straw-mulched furrow)and three planting densities(LD,low planting density,45.0×10^3 plants/hm^2;MD,medium planting density,67.5×10^3 plants/hm^2;HD,high planting density,90.0×10^3 plants/hm^2).Results showed that soil temperature was higher with RP and lower with SM compared with NM,but no significant difference was found between RPFS and NM.More soil water was retained by soil mulching at the early growth stage,but it significantly varied at the middle and late growth stages.Maize growth was significantly improved by soil mulching.With increasing planting density,stem diameter,net photosynthetic rate and chlorophyll content tended to decline,whereas a single-peak trend in biomass yield was observed.Mulching type and planting density did not have significant effect on evapotranspiration(ET),but GY and WUE were significantly affected.There were significant interacting effects of mulching type and planting density on biomass yield,GY,ET and WUE.Compared with NM,RPFS,RP and SM increased GY by 57.5%,50.8%and 18.9%,and increased WUE by 66.6%,54.3%and 18.1%,respectively.At MD,GY increased by 41.4%and 25.2%,and WUE increased by 38.6%and 22.4%compared with those of at LD and HD.The highest maize GY(7023.2 kg/hm^2)was observed under MD+RPFS,but the value(6699.1 kg/hm^2)was insignificant under MD+RP.Similar trends were observed for WUE under MD+RP and MD+RPFS,but no significant difference was observed between these two combinations.In terms of economic benefit,net income under MD+RP was the highest with a 9.8%increase compared with that of under MD+RPFS.Therefore,we concluded that RP cultivation pattern with a suitable planting density(67.5×10^3 plants/hm^2)is promising for rainwater resources utilization and maize production in the drylands of northern China. | ZHENG Jing FAN Junliang ZOU Yufeng Henry Wai CHAU ZHANG Fucang | 2020 | Journal of Arid Land2020，12，2： | 3 |
| 10 | Practical strategy to construct anti-osteosarcoma bone substitutes by loading cisplatin into 3D-printed titanium alloy implants using a thermosensitive hydrogel显示文摘Surgical resection and perioperative adjuvant chemotherapy-based therapies have improved the prognosis of patients with osteosarcoma;however,intraoperative bone defects,local tumour recurrence,and chemotherapy-induced adverse effects still affect the quality of life of patients.Emerging 3D-printed titanium alloy(Ti6Al4V)implants have advantages over traditional implants in bone repair,including lower elastic modulus,lower stiffness,better bone conduction,more bone in-growth,stronger mechanical interlocking,and lager drug-loading capacity by their inherent porous structure.Here,cisplatin,a clinical first-line anti-osteosarcoma drug,was loaded into Ti6Al4V implants,within a PLGA-PEG-PLGA thermo-sensitive hydrogel,to construct bone substitutes with both anti-osteosarcoma and bone-repair functions.The optimal concentrations of cisplatin(0.8 and 1.6 mg/mL)were first determined in vitro.Thereafter,the anti-tumour effect and biosafety of the cisplatin/hydrogel-loaded implants,as well as their bone-repair potential were evaluated in vivo in tumour-bearing mouse,and bone defect rabbit models,respectively.The loading of cisplatin reduced tumour volume by more than two-thirds(from 641.1 to 201.4 mm3)with negligible organ damage,achieving better anti-tumour effects while avoiding the adverse effects of systemic cisplatin delivery.Although bone repair was hindered by cisplatin loading at 4 weeks,no difference was observed at 8 weeks in the context of implants with versus without cisplatin,indicating acceptable long-term stability of all implants(with 8.48%-10.04%bone in-growth and 16.94%-20.53%osseointegration).Overall,cisplatin/hydrogel-loaded 3D-printed Ti6Al4V implants are safe and effective for treating osteosarcoma-caused bone defects,and should be considered for clinical use. | Zehao Jing Renhua Ni Jiedong Wang Xinhong Lin Daoyang Fan Qingguang Wei Teng Zhang Yufeng Zheng Hong Cai Zhongjun Liu | 2021 | Bioactive Materials2021，6，12： | 3 |
| 11 | Agronomic and physiological traits associated with genetic improvement of phosphorus use efficiency of wheat grown in a purple lithomorphic soil显示文摘Developing wheat that acquires and uses phosphorus(P)more efficiently is a promising and low-cost solution for increasing grain yield and reducing P-related environmental impacts.The present study identified agronomic and physiological traits that contribute to genetic variation in the P acquisition,remobilization,and utilization efficiency of 11 wheat cultivars from southwest China grown in P-deficient purple lithomorphic soil(Olsen P=4.7)with balanced(75 kg P ha^(−1))and excess P(120 kg P ha^(−1))supplies.On average,soil P deficiency(–P)reduced root P uptake(17.0%–60.8%),P remobilization(33.9%–52.8%),dry mass yield(11.5%–39.2%),and grain yield(17.7%–54.4%).Balanced P(+P)increased grain yield via increased plant biomass rather than increased HI.–P increased phosphorus uptake efficiency(PUpE,4.5-fold),phosphorus utilization efficiency(PUtE,1.25-fold),and phosphorus use efficiency(PUE,5.4-fold)compared with those under+P,and PUtE explained most(58.1%–60.8%)of the genetic variation in PUE under both–P and+P.The high root P uptake of P-efficient cultivars under–P was regulated by root surface area and root length density in the 0–10 cm soil layer but not in the 10–20 and 20–40 cm soil layers,suggesting that a topsoil foraging strategy is a more economical approach than deeper root exploration for increasing P uptake.Root P uptake before anthesis and P remobilization after anthesis were critical for increasing the PUtE of wheat,given that P-efficient cultivars showed higher Pn(net photosynthetic rate)and sucrose levels than P-inefficient cultivars.Pn reduction by–P resulted from decreased Gs and Ci,and high evapotranspiration under+P increased shoot P%by increasing root P uptake.Genetic variation in the source-to-sink ratio was observed in consequence of a+P-induced allometric increase in sucrose in leaves and kernels.Owing to these beneficial effects,+P increased the kernel N and P yields of the 11 cultivars by 9.9%–52.4%and 12.3%–48.8%,respectively.The findings of this study could help improve wheat in future breeding efforts and P management by identifying desirable Pefficient phenotypes in P-deficient farming systems. | Hongkun Yang Renhua Chen Yufeng Chen Han Li Ting Wei Wei Xie Gaoqiong Fan | 2022 | The Crop Journal2022，10，4： | 2 |
| 12 | Timing of formation of the Hongdonggou Pb-Zn polymetallic ore deposit,Henan Province,China:Evidence from Rb-Sr isotopic dating of sphalerites显示文摘The Hongdonggou Pb-Zn polymetallic ore deposit,located in the southwestern part of the Luanchuan Mo-W-Pb-Zn-Ag polymetallic ore mineralization in Henan Province,China,is an important part of the East Qinling metallogenic belt.The orebodies in the deposit,which are vein,bedded and lenticular,are mainly hosted in the syenite porphyry,and formed within the carbonate and clastic rocks of the Yuku and Qiumugou formations partially.The genesis of the deposit has previously been argued to be of hydrothermal-vein type or of skarn-hydrothermal type.In this study,we report the results of Rb-Sr isotopic dating based on sphalerites from the main orebody of the Hongdonggou Pb-Zn polymetallic ore deposit,which yield an isochron age of 135.7 ± 3.2 Ma,constraining the timing of mineralization as early Cretaceous.The age is close to those reported for the Pb-Zn deposits in the Luanchuan ore belt.The(^(87)Sr/^(86)Sr),values of the sphalerites(0.71127 + 0.00010) are lower than that of terrigenous silicates(0.720) and higher than the mantle(0.707),suggesting that the metallogenic components were mainly derived through crust-mantle mixing.Combining the results from this study with those from previous work,we propose that the Hongdonggou Pb-Zn polymetallic ore deposit is a hydrothermal-vein deposit associated with the early Cretaceous tectonothermal event,and the mineralization is controlled by NWand near EW-trending faults in the Luanchuan Mo-W-Pb-Zn-Ag polymetallic ore concentration belt. | Fan Yang Gongwen Wang Huawen Cao Ruixi Li Li Tang Yufeng Huang Hao Zhang Fei Xue Wenjuan Jia Nana Guo | 2017 | Geoscience Frontiers2017，8，3： | 2 |

| 16 | Free-standing hybrid films comprising of ultra-dispersed titania nanocrystals and hierarchical conductive network for excellent high rate performance of lithium storage显示文摘The construction of advanced electrode materials is key to the field of energy storage.Herein,a free-standing anatase titania(TiO_(2))nanocrystal/carbon nanotube(CNT)film is reported using a simple and scalable sol-gel method,followed by calcination.This unique free-standing film comprises ultra-small TiO_(2) nanocrystals(~5.9 nm)and super-aligned CNTs,with ultra-dispersed TiO_(2) nanocrystals on the surfaces of the CNTs.On the one hand,these TiO_(2) nanocrystals can significantly decrease the diffusion distance of the charges and on the other hand,the cross-linked CNTs can act as a three-dimensional(3D)conductive network,allowing the fast transport of electrons.In addition,the film is free-standing,without requiring electrode fabrication and additional conductive agents and binders.Owing to these above synergistic effects,the film is directly used as an anode in Li-ion batteries,and delivers a high discharge capacity of~105 mAh·g^(−1) at high rate of 60 C(1 C=170 mA·g^(−1))and excellent cycling performance over 2,500 cycles at 30 C.These results indicate that the free-standing anatase TiO_(2) nanocrystal/CNT film affords a superior performance among the various TiO_(2) materials and can be a promising anode material for fast-charging Li-ion batteries.Moreover,the TiO_(2)/CNT film exhibits an areal capacity of up to 2.4 mAh·cm^(−2),confirming the possibility of its practical use. | Kunlei Zhu Chenyu Li Yushuang Jiao Jiawen Zhu Hongtao Ren Yufeng Luo Shoushan Fan Kai Liu | 2021 | Nano Research2021，14，7： | 1 |
| 17 | Reducing Viral Inhibition of Host Cellular Apoptosis Strengthens the Immunogenicity and Protective Efficacy of an Attenuated HSV-1 Strain显示文摘Herpes simplex virus 1(HSV-1),a member of a herpesviruses,shows a high infectivity rate of 30%-60%in populations of various ages.Some herpes simplex(HSV)vaccine candidates evaluated during the past 20 years have not shown protective efficacy against viral infection.An improved understanding of the immune profile of infected individuals and the associated mechanism is needed.HSV uses an immune evasion strategy during viral replication,and various virus-encoded proteins,such as ICP47 and Vhs,participate in this process through limiting the ability of CD8+cytotoxic T lymphocytes to recognize target cells.Other proteins,e.g.,Us3 and Us5,also play a role in viral immune evasion via interfering with cellular apoptosis.In this work,to study the mechanism by which HSV-1 strain attenuation interferes with the viral immune evasion strategy,we constructed a mutant strain,M5,with deletions in the Us3 and Us5 genes.M5 was shown to induce higher neutralizing antibody titers and a stronger cellular immune response than our previously reported M3 strain,and to prevent virus infection more effectively than the M3 strain in an in vivo mouse challenge test. | Xingli Xu Yufeng He Shengtao Fan Min Feng Guorun Jiang Lichun Wang Ying Zhang Yun Liao Qihan Li | 2019 | Virologica Sinica2019，34，6： | 1 |
