| 4 | 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 |
| 5 | Consensus on the application of negative pressure wound therapy of diabetic foot wounds显示文摘Because China is becoming an aging society,the incidence of diabetes and diabetic foot have been increasing.Diabetic foot has become one of the main health-related killers due to its high disability and mortality rates.Negative pressure wound therapy(NPWT)is one of the most effective techniques for the treatment of diabetic foot wounds and great progress,both in terms of research and its clinical application,has been made in the last 20 years of its development.However,due to the complex pathogenesis and management of diabetic foot,irregular application of NPWT often leads to complications,such as infection,bleeding and necrosis,that seriously affect its treatment outcomes.In 2020,under the leadership of Burns,Trauma and Tissue Repair Committee of the Cross-Straits Medicine Exchange Association,the writing group for‘Consensus on the application of negative pressure wound therapy of diabetic foot wounds’was established with the participation of scholars from the specialized areas of burns,endocrinology,vascular surgery,orthopedics and wound repair.Drawing on evidence-based practice suggested by the latest clinical research,this consensus proposes the best clinical practice guidelines for the application and prognostic evaluation of NPWT for diabetic foot.The consensus aims to support the formation of standardized treatment schemes that clinicians can refer to when treating cases of diabetic foot. | Shizhao Ji Xiaobin Liu Jie Huang Junmin Bao Zhaohong Chen Chunmao Han Daifeng Hao Jingsong Hong Dahai Hu Yufeng Jiang Shang Ju Hongye Li Zongyu Li Guangping Liang Yan Liu Gaoxing Luo Guozhong Lv Xingwu Ran Zhongmin Shi Juyu Tang Aiping Wang Guangyi Wang Jiangning Wang Xin Wang Bing Wen Jun Wu Hailin Xu Maojin Xu Xiaofei Ye Liangxi Yuan Yi Zhang Shichu Xiao Zhaofan Xia | 2021 | Burns & Trauma2021，9，1： | 17 |

| 14 | Clinical characteristics and effectiveness of antiviral agents in hospitalized children with infectious mononucleosis in China:A multicenter retrospective study显示文摘Importance:The clinical characteristics of infectious mononucleosis(IM)in Chinese children have not been evaluated in multicenter studies,and the effectiveness of antiviral treatment are controversial.Objective:To investigate the clinical characteristics of Chinese children with IM and current status of antiviral therapy for affected patients.Methods:Hospitalized patients with IM were enrolled between 2018 and 2020 in five children’s hospitals in China.The clinical characteristics were compared among four age groups:<3 years,3-<6 years,6-<10 years,and≥10 years.The clinical characteristics of IM and effectiveness of antiviral therapy were compared among patients receiving acyclovir(ACV),ganciclovir(GCV),and no antiviral therapy(i.e.,non-antiviral group).Results:In total,499 patients were analyzed;most patients were 3-<6 years of age.The most common symptoms and signs included fever(100%),lymphadenopathy(98.6%),pharyngitis(86.4%),eyelid edema(76.8%),and snoring(72.9%).There were significant differences in rash,hepatomegaly,and liver dysfunction among the four age groups.Patients aged<3 years had a lower incidence of liver dysfunction and a higher incidence of rash.Among the 499 patients,50.1%were treated with GCV,26.3%were treated with ACV,and 23.6%received no antiviral therapy.Compared with the non-antiviral group,patients in the ACV and GCV groups had longer durations of fever(P<0.001).There were no significant differences in the incidences of complications among the three treatment groups.Interpretation:The incidence of IM in Chinese children peaked at 3-<6 years of age.Clinical features of IM varied according to age.Patients receiving antiviral therapy exhibited more serious clinical manifestations than did patients without antiviral therapy.The effectiveness of antiviral therapy for IM requires further analysis. | Huili Hu Huiling Deng Jing Bi Yi Xu Shuangjie Li Yue Xie Xinrong Sun Dongmeng Wang Xufang Li Wenxian Ouyang Bing Hu Yufeng Zhang He Tang Chunxiao Fang Hui Zhang Lingyun Guo Chen Wang Tianyi Wang Fengxia Yang Tao Jiang Zhengde Xie Gang Liu | 2021 | Pediatric Investigation2021，5，3： | 12 |
| 15 | Fault diagnosis of wind turbine bearing based on stochastic subspace identification and multi-kernel support vector machine显示文摘In order to accurately identify a bearing fault on a wind turbine, a novel fault diagnosis method based on stochastic subspace identification(SSI) and multi-kernel support vector machine(MSVM) is proposed. Firstly, the collected vibration signal of the wind turbine bearing is processed by the SSI method to extract fault feature vectors. Then, the MSVM is constructed based on Gauss kernel support vector machine(SVM) and polynomial kernel SVM. Finally, fault feature vectors which indicate the condition of the wind turbine bearing are inputted to the MSVM for fault pattern recognition. The results indicate that the SSI-MSVM method is effective in fault diagnosis for a wind turbine bearing and can successfully identify fault types of bearing and achieve higher diagnostic accuracy than that of K-means clustering, fuzzy means clustering and traditional SVM. | Hongshan ZHAO Yufeng GAO Huihai LIU Lang LI | 2019 | Journal of Modern Power Systems and Clean Energy2019，7，2： | 12 |
| 16 | Growth response and toxic effects of three antibiotics on Selenastrum capricornutum evaluated by photosynthetic rate and chlorophyll biosynthesis显示文摘The effects of three types of antibiotics (erythromycin,ciprofloxacin and sulfamethoxazole) on the photosynthesis of freshwater algae,Selenastrum capricornutum Printz,were investigated by determining the growth rate,chloroplast pigments content,seven main precursors (including δ-aminolevulinic acid,porphobilinogen,uroporphyrinogen III,coproporphyrinogen III,protoporphyrin IX,Mg-proporphyrin IX and protochlorophyllide),and photosynthetic rate during chlorophyll biosynthesis.The antibiotics significantly decreased the growth rate,chlorophyll content,and photosynthetic rate.Erythromycin induced a decreasing effect at a concentration of 0.06 mg/L,while ciprofloxacin and sulfamethoxazole achieved the same results at concentrations higher than 1.5 mg/L.Only erythromycin significantly inhibited chlorophyll biosynthesis,which indicated that it was considerably more toxic to S.capricornutum than ciprofloxacin and sulfamethoxazole,and may pose a high potential risk to aquatic ecosystems. | Binyang Liu Weiqiu Liu Xiangping Nie Chao Guan Yufeng Yang Zhaohui Wang Wei Liao | 2011 | Journal of Environmental Sciences2011，23，9： | 11 |
| 17 | Rapid generation of genetic diversity by multiplex CRISPR/Cas9 genome editing in rice显示文摘The clustered regularly interspaced short palindromic repeats(CRISPR)-associated endonuclease 9(CRISPR/Cas9) system has emerged as a promising technology for specific genome editing in many species. Here we constructed one vector targeting eight agronomic genes in rice using the CRISPR/Cas9 multiplex genome editing system. By subsequent genetic transformation and DNA sequencing, we found that the eight target genes have high mutation efficiencies in the T_0 generation. Both heterozygous and homozygous mutations of all editing genes were obtained in T_0 plants. In addition, homozygous sextuple, septuple, and octuple mutants were identified. As the abundant genotypes in T_0 transgenic plants, various phenotypes related to the editing genes were observed. The findings demonstrate the potential of the CRISPR/Cas9 system for rapid introduction of genetic diversity during crop breeding. | Lan Shen Yufeng Hua Yaping Fu Jian Li Qing Liu Xiaozhen Jiao Gaowei Xin Junjie Wang Xingchun Wang Changjie Yan Kejian Wang | 2017 | Science China(Life Sciences)2017，60，5： | 11 |
| 18 | Microstructure, Mechanical Properties, Corrosion Behavior and Biocompatibility of As-Extruded Biodegradable Mg–3Sn–1Zn–0.5Mn Alloy显示文摘The microstructure evolution and mechanical properties of biodegradable Mg–3Sn–1Zn–0.5Mn alloys were investigated by the optical microscopy, X-ray diffractometer and a universal material testing machine.The corrosion and degradation behaviors were studied by potentiodynamic polarization method and immersion test in a simulated body fluid(SBF). It was found that the as-extruded Mg–3Sn–1Zn–0.5Mn alloy has the fine equiaxed grains which underwent complete dynamic recrystallization during the hot extrusion process, with the second phase particles of Mg_2Sn precipitated on the grain boundaries and inside the grains. The tensile strength and elongation of as-extruded Mg–3Sn–1Zn–0.5Mn alloys were 244 ± 3.7 MPa and 19.3% ± 1.7%, respectively. The potentiodynamic polarization curves in SBF solution indicated the better corrosion resistance of the as-extruded Mg–3Sn–1Zn–0.5Mn alloy in the SBF solution. Immersion test in the SBF solution for 720 h revealed that the corrosion rate of as-extruded Mg–3Sn–1Zn–0.5Mn alloy was nearly 4 ± 0.33 mm/year. The hemolysis rate of as-extruded Mg–3Sn–1Zn–0.5Mn alloy was lower than the safe value of 5% according to ISO 10993-4. As-extruded Mg–3Sn–1Zn–0.5Mn alloy showed good biocompatibility after being implanted into the dorsal muscle and the femoral shaft of the rabbit, and no abnormalities were found after short-term implantation. It was revealed that the as-extruded Mg–3Sn–1Zn–0.5Mn alloy is a promising material for biodegradable implants,which possesses an interesting combination of preferred mechanical properties, better corrosion resistance and biocompatibility. | Lida Hou Zhen Li Hong Zhao Yu Pan Sergey Pavlinich Xiwei Liu Xinlin Li Yufeng Zheng Li Li | 2016 | Journal of Materials Science & Technology2016，32，9： | 10 |
| 19 | 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 |
| 20 | 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 |
