3Development and validation of an endoscopic images-based deep learning model for detection with nasopharyngeal malignancies显示文摘Background:Due to the occult anatomic location of the nasopharynx and frequent presence of adenoid hyperpla-sia,the positive rate for malignancy identification during biopsy is low,thus leading to delayed or missed diagnosis for nasopharyngeal malignancies upon initial attempt.Here,we aimed to develop an artificial intelligence tool to detect nasopharyngeal malignancies under endoscopic examination based on deep learning.Methods:An endoscopic images-based nasopharyngeal malignancy detection model(eNPM-DM)consisting of a fully convolutional network based on the inception architecture was developed and fine-tuned using separate training and validation sets for both classification and segmentation.Briefly,a total of 28,966 qualified images were collected.Among these images,27,536 biopsy-proven images from 7951 individuals obtained from January 1st,2008,to December 31st,2016,were split into the training,validation and test sets at a ratio of 7:1:2 using simple randomiza-tion.Additionally,1430 images obtained from January 1st,2017,to March 31st,2017,were used as a prospective test set to compare the performance of the established model against oncologist evaluation.The dice similarity coef-ficient(DSC)was used to evaluate the efficiency of eNPM-DM in automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images,by comparing automatic segmentation with manual segmenta-tion performed by the experts.Results:All images were histopathologically confirmed,and included 5713(19.7%)normal control,19,107(66.0%)nasopharyngeal carcinoma(NPC),335(1.2%)NPC and 3811(13.2%)benign diseases.The eNPM-DM attained an overall accuracy of 88.7%(95%confidence interval(CI)87.8%-89.5%)in detecting malignancies in the test set.In the prospective comparison phase,eNPM-DM outperformed the experts:the overall accuracy was 88.0%(95%CI 86.1%-89.6%)vs.80.5%(95%CI 77.0%-84.0%).The eNPM-DM required less time(40 s vs.110.0±5.8 min)and exhibited encouraging performance in automatic segmentation of nasopharyngeal malignant area from the background,with an average DSC of 0.78±0.24 and 0.75±0.26 in the test and prospective test sets,respectively.Conclusions:The eNPM-DM outperformed oncologist evaluation in diagnostic classification of nasopharyngeal mass into benign versus malignant,and realized automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images.Chaofeng Li Bingzhong Jing Liangru Ke Bin Li Weixiong Xia Caisheng He Chaonan Qian Chong Zhao Haiqiang Mai Mingyuan Chen Kajia Cao Haoyuan Mo Ling Guo Qiuyan Chen Linquan Tang Wenze Qiu Yahui Yu Hu Liang Xinjun Huang Guoying Liu Wangzhong Li Lin Wang Rui Sun Xiong Zou Shanshan Guo Peiyu Huang Donghua Luo Fang Qiu Yishan Wu Yijun Hua Kuiyuan Liu Shuhui Lv Jingjing Miao Yanqun Xiang Ying Sun Xiang Guo Xing Lv 2018Cancer Communications2018,38,1:9
4A Human Body Posture Recognition Algorithm Based on BP Neural Network for Wireless Body Area Networks显示文摘Human body posture recognition has attracted considerable attention in recent years in wireless body area networks(WBAN). In order to precisely recognize human body posture,many recognition algorithms have been proposed.However, the recognition rate is relatively low. In this paper, we apply back propagation(BP) neural network as a classifier to recognizing human body posture, where signals are collected from VG350 acceleration sensor and a posture signal collection system based on WBAN is designed. Human body signal vector magnitude(SVM) and tri-axial acceleration sensor data are used to describe the human body postures. We are able to recognize 4postures: Walk, Run, Squat and Sit. Our posture recognition rate is up to 91.67%. Furthermore, we find an implied relationship between hidden layer neurons and the posture recognition rate. The proposed human body posture recognition algorithm lays the foundation for the subsequent applications.Fengye Hu Lu Wang Shanshan Wang Xiaolan Liu Gengxin He 2016China Communications2016,13,8:9

6Deep-learning-based ciphertext-only attack on optical double random phase encryption显示文摘Optical cryptanalysis is essential to the further investigation of more secure optical cryptosystems.Learning-based at-tack of optical encryption eliminates the need for the retrieval of random phase keys of optical encryption systems but it is limited for practical applications since it requires a large set of plaintext-ciphertext pairs for the cryptosystem to be at-tacked.Here,we propose a two-step deep learning strategy for ciphertext-only attack(COA)on the classical double ran-dom phase encryption(DRPE).Specifically,we construct a virtual DRPE system to gather the training data.Besides,we divide the inverse problem in COA into two more specific inverse problems and employ two deep neural networks(DNNs)to respectively learn the removal of speckle noise in the autocorrelation domain and the de-correlation operation to retrieve the plaintext image.With these two trained DNNs at hand,we show that the plaintext can be predicted in real-time from an unknown ciphertext alone.The proposed learning-based COA method dispenses with not only the retrieval of random phase keys but also the invasive data acquisition of plaintext-ciphertext pairs in the DPRE system.Numerical simulations and optical experiments demonstrate the feasibility and effectiveness of the proposed learning-based COA method.Meihua Liao Shanshan Zheng Shuixin Pan Dajiang Lu Wenqi He Guohai Situ Xiang Peng 2021Opto-Electronic Advances2021,4,5:7
7Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study显示文摘Background:Famitinib is a tyrosine kinase inhibitor against multiple targets,including vascular endothelial growth factor receptor 2/3,platelet-derived growth factor receptor,and stem cell factor receptor(c-kit).Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers.We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy(CCRT)in patients with locoregionally advanced nasopharyngeal carcinoma(NPC).We also evaluated the feasibility of contrast-enhanced ultrasound(D-CEUS)as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy.Methods:The trial was conducted in subjects with stage III or IVa-b NPC using a 3+3 design of escalating fami-tinib doses.Briefly,subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT.D-CEUS of the neck lymph nodes was performed at day 0,8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy.End points included safety,tolerability and anti-tumour activity.Results:Twenty patients were enrolled(six each for 12.5,16.5 and 20 mg and two for 25 mg).Two patients in the 25 mg cohort developed dose-limiting toxicities,including grade 4 thrombocytopenia and grade 3 hypertension.The most common grade 3/4 adverse events were leukopenia,neutropenia and radiation mucositis.D-CEUS tests showed that more than 60%of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone,and the parameter response was associated with disease improvement.In the famitinib monotherapy stage,three patients(15%)showed partial responses.The complete response rate was 65%at the completion of treatment and 95%3 months after the treatment ended.After a median follow-up of 44 months,the 3-year progression-free survival(PFS)and distant metastasis-free survival were 70%and 75%,respectively.Subjects with a decrease of perfusion parameter response,such as peak intensity decreased at least 30%after 1 week of famitinib treatment,had higher 3-year PFS(90.9%vs.44.4%,95%CI 73.7%-100%vs.11.9%-76.9%,P<0.001)than those with an increase or a reduction of less than 30%.Conclusions:The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC.D-CEUS is a reliable and early measure of efficacy for famitinib therapies.Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy.Qiuyan Chen Linquan Tang Na Liu Feng Han Ling Guo Shanshan Guo Jianwei Wang Huai Liu Yanfang Ye Lu Zhang Liting Liu Pan Wang Yingqin Li Qingmei He Xiaoqun Yang Qingnan Tang Yang Li YuJing Liang XueSong Sun Chuanmiao Xie Yunxian Mo Ying Guo Rui Sun Haoyuan Mo Kajia Cao Xiang Guo Musheng Zeng Haiqiang Mai Jun Ma 2018Cancer Communications2018,38,1:6
8Magnetic performance and corrosion resistance of electroless plating CoWP film显示文摘The CoWP film with good magnetic performance and corrosion resistance was electrolessly plated from alkaline solution. The technical parameters of the electroless plating system were optimized. When the pH value of electroless plating solution was 11.0 and the reducing agent (NaH2PO2) content was 0.4 mol L 1, the target chemical reactions proceeded in the electroless plating solution smoothly with negligible interference and side effects. CoWP film prepared under optimal deposition condition contained more hexagonal close-packed (hcp) cobalt (ε-Co) of [110] and crystallographic orientation of Co [002]. VSM analysis reveals that the saturation magnetization of the CoWP film is 100~220 Am2 kg 1 and coercivity is (2.87~4.38)×104 A·cm 1. The corrosion behavior of CoWP film in 3.5% NaCl aqueous solution was studied by electrochemical experiments. The results prove that the corrosion resistance of the CoWP film deposited under the optimal depo-sition condition exhibites relatively lower corrosion current of (3.054~3.162)×10 6 A·cm 2. The surface morphology analysis indicates that the film is smooth and composed of regular-shaped crystallites.Jiang, Li Pan, Shanshan Lu, Jianbiao Ke, Xin He, Wenhao Yu, Yundan Wei, Guoying Ge, Hongliang 2012Rare Metals2012,31,3:6
9Clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma显示文摘Objective: To assess the clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma(DLBCL).Methods: A retrospective study of 37 patients with primary testicular DLBCL was carried out from November 2003 to May 2012. Their clinical features, survival and prognostic factors were analyzed.Results: During a median follow-up period of 39.8 months(5.4-93.0 months), the median progression-free survival(PFS) was 26.2 months(95% CI: 0-65 months) and the 3-year overall survival(OS) rate was 78.4%. Within the whole cohort, the factors significantly associated with a superior PFS were limited stage(stage I/II), lactate dehydrogenase(LDH) ≤245 U/L, international prognostic index(IPI) ≤1, primary tumor diameter <7.5 cm, and patients who had complete response(CR) and received doxorubicin-contained chemotherapy(P<0.05). There was a trend toward superior outcome for patients who received combined therapy(surgery/chemotherapy/radiotherapy)(P=0.055). Patients who had CR, primary tumor diameter <7.5 cm and IPI score ≤1 were significantly associated with longer PFS at multivariate analysis.Conclusions: Primary testicular DLBCL had poorer survival. CR, primary tumor diameter and IPI were independent prognostic factors. The combined therapy of orchectomy, doxorubicin-contained chemotherapy and contralateral testicular radiotherapy(RT) seemed to improve survival.Bo Jia Yuankai Shi Mei Dong Fengyi Feng Sheng Yang Hua Lin Liqiang Zhou Shengyu Zhou Shanshan Chen Jianliang Yang Peng Liu Yan Qin Changgong Zhang Lin Gui Lin Wang Xue Wang Xiaohui He 2014Chinese Journal of Cancer Research2014,26,4:5
10Impacts of exercise interventions on different diseases and organ functions in mice显示文摘Background'. In recent years, much evidence has emerged to indicate that exercise can benefit people when performed properly. This reviewsummarizes the exercise interventions used in studies involving mice as they are related to special diseases or physiological status. To furtherunderstand the effects of exercise interventions in treating or preventing diseases, it is important to establish a template for exercise interventionsthat can be used in future exercise-related studies.Methods'. PubMed was used as the data resource for articles. To identify studies related to the effectiveness of exercise interventions for treatingvarious diseases and organ functions in mice, we used the following search language: (exercise [Title] OR training [Title] OR physical activity[Title]) AND (mice [title/abstract] OR mouse [title/abstract] OR mus [title/abstract]). To limit the range of search results, we included 2 filters:one that limited publication dates to 'in 10 years,^ and one that sorted the results as 'best match^^. Then we grouped the commonly used exercisemethods according to their similarities and differences. We then evaluated the effectiveness of the exercise interventions for their impact on diseasesand organ functions in 8 different systems.Results'. A total of 331 articles were included in the analysis procedure. The articles were then segmented into 8 systems for which the exerciseinterventions were used in targeting and treating disorders: motor system (60 studies), metabolic system (45 studies), cardio-cerebral vascularsystem (58 studies), nervous system (74 studies), immune system (32 studies), respiratory system (7 studies), digestive system (1 study), and thesystem related to the development of cancer (54 studies). The methods of exercise interventions mainly involved the use of treadmills, voluntarywheel-running, forced wheel-running, swimming, and resistance training. It was found that regardless of the specific exercise method used, mostof them demonstrated positive effects on various systemic diseases and organ functions. Most diseases were remitted with exercise regardless ofthe exercise method used, although some diseases showed the best remission effects when a specific method was used.Conclusion-. Our review strongly suggests that exercise intervention is a cornerstone in disease prevention and treatment in mice. Because exerciseinterventions in humans typically focus on chronic diseases, national fitness, and body weight loss, and typically have low intervention com・pliance rates, it is important to use mice models to investigate the molecular mechanisms underlying the health benefits from exerciseinterventions in humans.Shanshan Guo Yiru Huang Yan Zhang He Huang Shangyu Hong Tiemin Liu 2020Journal of Sport and Health Science2020,9,1:5
11AFAP1-AS1: a rising star among oncogenic long non-coding RNAs显示文摘Long non-coding RNAs(lncRNAs)have become a hotspot in biomedical research.This interest reflects their extensive involvement in the regulation of the expression of other genes,and their influence on the occurrence and development of a variety of human diseases.Actin filament associated protein 1-Antisense RNA 1(AFAP1-AS1)is a recently discovered oncogenic lncRNA.It is highly expressed in a variety of solid tumors,and regulates the expression of downstream genes and signaling pathways through adsorption and competing microRNAs,or by the direct binding to other proteins.Ultimately,AFAP1-AS1 promotes proliferation,chemotherapy resistance,and resistance to apoptosis,maintains stemness,and enhances invasion and migration of tumor cells.This paper summarizes the research concerning AFAP1-AS1 in malignant tumors,including the clinical application prospects of AFAP1-AS1 as a potential molecular marker and therapeutic target of malignant tumors.We also discuss the limitations in the knowledge of AFAP1-AS1 and directions of further research.AFAP1-AS1 is expected to provide an example for studies of other lncRNA molecules.Fang Xiong Kunjie Zhu Su Deng Hongbin Huang Liting Yang Zhaojian Gong Lei Shi Yi He Yanyan Tang Qianjin Liao Jianjun Yu Xiaoling Li Yong Li Guiyuan Li Zhaoyang Zeng Wei Xiong Shanshan Zhang Can Guo 2021Science China(Life Sciences)2021,64,10:4
12Indium-gallium-zinc-oxide thin-film transistors:Materials,devices,and applications显示文摘Since the invention of amorphous indium-gallium-zinc-oxide(IGZO)based thin-film transistors(TFTs)by Hideo Hosono in 2004,investigations on the topic of IGZO TFTs have been rapidly expanded thanks to their high electrical performance,large-area uniformity,and low processing temperature.This article reviews the recent progress and major trends in the field of IGZO-based TFTs.After a brief introduction of the history of IGZO and the main advantages of IGZO-based TFTs,an overview of IGZO materials and IGZO-based TFTs is given.In this part,IGZO material electron travelling orbitals and deposition methods are introduced,and the specific device structures and electrical performance are also presented.Afterwards,the recent advances of IGZO-based TFT applications are summarized,including flat panel display drivers,novel sensors,and emerging neuromorphic systems.In particular,the realization of flexible electronic systems is discussed.The last part of this review consists of the conclusions and gives an outlook over the field with a prediction for the future.Ying Zhu Yongli He Shanshan Jiang Li Zhu Chunsheng Chen Qing Wan 2021Journal of Semiconductors2021,42,3:4
13A novel graphene oxide-carbon nanotubes anchored α-FeOOH hybrid activated persulfate system for enhanced degradation of Orange Ⅱ显示文摘Persulfate activation has been applied as one of the efficient advanced oxidation processes(AOPs) to remediate polluted environments. In this study, a novel α-FeOOH anchored by graphene oxide(GO)-carbon nanotubes(CNTs) aerogel(α-FeOOH@GCA) nanocomposite activated persulfate system(α-FeOOH@GCA + K2S2O8) was applied for decolorization of Orange Ⅱ(OⅡ). The decolorization of OⅡ was remarkably enhanced to a level of ~ 99% in this system compared with that of pristine α-FeOOH(~ 44%) or GO-CNTs(~18%). The enhanced catalytic activity of α-FeOOH@GCA was due to the formation of a heterojunction byα-FeOOH and GO-CNTs as confirmed by the presence of Fe–O–C chemical bonds. The degradation intermediates of OⅡ were comprehensively identified. The proposed degradation pathway of OⅡ begins with the destruction of the conjugated structures of OⅡ by the dominant reactive oxygen species, surface-bound SO4·-. The decolorization efficiency of OⅡ by the α-FeOOH@GCA activated persulfate system decreased from the first to third cycle of recycling. Ultraviolet(UV) irradiation or introduction of a small amount of Fe2+ could restore the activation of this system. The results show that the α-FeOOH@GCA persulfate activation system promises to be a highly efficient environmental remediation method for organic pollutants.Shanshan Su Yuyang Liu Wei He Xianchun Tang Wei Jin Yaping Zhao 2019Journal of Environmental Sciences2019,31,9:4
14Genetic architecture and key genes controlling the diversity of oil composition in rice grains显示文摘Rice grain oil is a valuable nutrient source.However,the genetic basis of oil biosynthesis in rice grains remains unclear.In this study,we performed a genome-wide association study on oil composition and oil concentration in a diverse panel of 533 cultivated rice accessions.High variation for 11 oil-related traits was observed,and the oil composition of rice grains showed differentiation among the subpopulations.We identified 46 loci that are significantly associated with grain oil concentration or composition,16 of which were detected in three recombinant inbred line populations.Twenty-six candidate genes encoding enzymes involved in oil metabolism were identified from these 46 loci,four of which(PAL6,LIN6,MYR2,and ARA6)were found to contribute to natural variation in oil composition and to show differentiation among the subpopulations.Interestingly,population genetic analyses revealed that specific haplotypes of PAL6 and LIN6 have been selected in japonica rice.Based on these results,we propose a possible oil biosynthetic pathway in rice grains.Collectively,our results provide new insights into the genetic basis of oil biosynthesis in rice grains and can facilitate marker-based breeding of rice varieties with enhanced oil and grain quality.Hao Zhou Duo Xia Pingbo Li Yiting Ao Xiaodong Xu Shanshan Wan Yanhua Li Bian Wu Huan Shi Kaiyue Wang Guanjun Gao Qinglu Zhang Gongwei Wang Jinghua Xiao Xianghua Li Sibin Yu Xingming Lian Yuqing He 2021Molecular Plant2021,14,3:4
15Development of nanoscale drug delivery systems of dihydroartemisinin for cancer therapy: A review显示文摘Dihydroartemisinin(DHA),a first-line antimalarial drug,has demonstrated great anticancer effects in many types of tumors,including liver cancer,glioblastoma,and pancreatic cancer.Due to its abilities to induce programmed cell death(PCD;apoptosis,autophagy and ferroptosis),inhibit tumor metastasis and angiogenesis,and modulate the tumor microenvironment,DHA could become an antineoplastic agent in the foreseeable future.However,the therapeutic efficacy of DHA is compromised owing to its inherent disadvantages,including poor stability,low aqueous solubility,and short plasma halflife.To overcome these drawbacks,nanoscale drug delivery systems(NDDSs),such as polymeric nanoparticles(NPs),liposomes,and metal-organic frameworks(MOFs),have been introduced to maximize the therapeutic efficacy of DHA in either single-drug or multidrug therapy.Based on the beneficial properties of NDDSs,including enhanced stability and solubility of the drug,prolonged circulation time and selective accumulation in tumors,the outcomes of DHA-loaded NDDSs for cancer therapy are significantly improved compared to those of free DHA.This reviewfirst summarizes the current understanding of the anticancer mechanisms of DHA and then provides an overview of DHA-including nanomedicines,aiming to provide inspiration for further application of DHA as an anticancer drug.Ka Hong Wong Donglin Yang Shanshan Chen Chengwei He Meiwan Chen 2022Asian Journal of Pharmaceutical Sciences2022,17,4:3
16Preparation of MCM-41-supported chiral Salen Mn (III) catalysts and their catalytic properties in the asymmetric epoxidation of olefins显示文摘A secondary amino-modified mesoporous molecular sieve MCM-41 was obtained by reaction of bis(3-(triethoxysilyl)propyl)amine with MCM-41. The chiral Salen-Mn (III) complex was anchored onto the modified MCM-41 by a multi-step grafting method and two heterogenized catalysts with different Mn contents were obtained. The catalysts were characterized by XRD, N2 adsorption, ICP, FT-IR and DR UV-Vis. Their catalysis on asymmetric epoxidation of several olefins was studied with NaClO and m-CPBA as oxidants respectively. It was found that both the activity and enantioselectivity of the cata- lysts decreased after the homogeneous catalyst was heterogenized. The reasons resulting in the de- crease of catalytic performance were discussed.ZHAO DongMin ZHAO JiQuant ZHAO ShanShan HE LeQin WANG WeiYu 2007Chinese Science Bulletin2007,52,17:3

18Addition of rituximab is not associated with survival benefit compared with CHOP alone for patients with stage I diffuse large B-cell lymphoma显示文摘Background:The role of rituximab in combination with CHOP regimen in patients with stage I diffuse large B-cell lymphoma(DLBCL) remains to be defined.We aimed to compare CHOP plus rituximab(R-CHOP) with CHOP alone and determine the value of radiotherapy in these patients.Methods:Between 2003 and 2009,140 untreated patients with stage I DLBCL were retrospectively analyzed in this study.Results:Seventy-eight patients were treated in R-CHOP group and 62 in CHOP group.Ninety-one patients received additional radiotherapy at the end of chemotherapy.The different treatment groups were well-balanced with respect to baseline characteristics.Complete response(CR) rate was 77% both in R-CHOP and CHOP groups(P=0.945).After a median follow-up period of 56 months,patients received R-CHOP regimen had similar 5-year progression-free survival(PFS)(76%vs.85%;log-rank P=0.215)and 5-year overall survival(OS)(90%vs.96%;log-rank P=0.175) compared with those with CHOP alone.Patients with radiotherapy had significantly increased 5-year PFS compared with those who had chemotherapy alone(86%vs.71%;log-rank P=0.005).At multivariate analysis,patients who had CR(P=0.008) and received radiotherapy(P=0.003) were significantly associated with superior PFS.Conclusions:CHOP alone could be as effective as R-CHOP regimen and additional radiotherapy would be necessary for stage I or stage I non-bulky DLBCL patients.Bo Jia Yuankai Shi Suyi Kang Sheng Yang Shaoxuan Hu Yexiong Li Mei Dong Weihu Wang Jianliang Yang Liqiang Zhou Peng Liu Shengyu Zhou Yan Qin Lin Gui Changgong Zhang Hua Lin Shanshan Chen Lin Wang Xiaohui He 2015Chinese Journal of Cancer Research2015,27,5:2
19Comparative transcriptome analysis of purple-fleshed sweet potato provides insights into the molecular mechanism of anthocyanin biosynthesis显示文摘Sweet potato, Ipomoea batatas, is a globally important food crop. The purple-fleshed sweet potato, rich in anthocyanins, has great potential for both nutritional and pharmaceutical uses. In this study, we characterized the root transcriptomes of the purple-fleshed sweet potato cv.Jingshu 6 and its mutant JS6-5 with high anthocyanin content by high-throughput RNA sequencing. A total of22873364 and 27955097 high quality reads were obtained from Jingshu 6 and JS6-5, respectively, and assembled into35592 unigenes. In all, we obtained 1566 differentially expressed genes(DEGs). Among them, 994 were upregulated and 572 were downregulated in JS6-5 compared to the expression in Jingshu 6. A total of 1436 DEGs were annotated, in which 847 DEGs had gene ontology(GO) terms and 329 DEGs were assigned to 84 Kyoto Encyclopedia of Genes and Genomes(KEGG)pathways. Most importantly, 23 differentially expressed genes and 24 transcription factors were identified as candidate genes involved in anthocyanin biosynthesis. In addition, 2349 SSRs were detected. This study not only provides the candidate genes but also provides insights into the molecular mechanism of anthocyanin biosynthesis in sweet potato.Hongyuan ZHAO Shanshan ZHANG Feibing WANG Ning ZHAO Shaozhen HE Qingchang LIU Hong ZHAI 2018Frontiers of Agricultural Science and Engineering2018,5,2:2
