| 1 | Novel Magnesium Alloys Developed for Biomedical Application:A Review显示文摘There is an increasing interest in the development of magnesium alloys both for industrial and biomedical applications.Industrial interest in magnesium alloys is based on strong demand of weight reduction of transportation vehicles for better fuel efficiency,so higher strength,and better ductility and corrosion resistance are required.Nevertheless,biomedical magnesium alloys require appropriate mechanical properties, suitable degradation rate in physiological environment,and what is most important,biosafety to human body. Rather than simply apply commercial magnesium alloys to biomedical field,new alloys should be designed from the point of view of nutriology and toxicology.This article provides a review of state-of-the-art of magnesium alloy implants and devices for orthopedic,cardiovascular and tissue engineering applications. Advances in new alloy design,novel structure design and surface modification are overviewed.The factors that influence the corrosion behavior of magnesium alloys are discussed and the strategy in the future development of biomedical magnesium alloys is proposed. | Nan Li Yufeng Zheng | 2013 | Journal of Materials Science & Technology2013，29，6： | 58 |

| 3 | Strategic Interaction in Spending on Environmental Protection:Spatial Evidence from Chinese Cities显示文摘In China,the responsibility of protecting the environment lies largely with local governments. Within the framework of spatial econometrics,we investigate empirically the consequence of such an institutional setting.Using city-level data for China,the present study finds that city governments behave strategically in making spending decisions regarding environmental protection.This paper finds that a city government appears to cut its own spending as a response to the rise in environmental protection spending by its neighbors.Hence, environmental protection tends to be underprovided.As a result,we suggest that centralizing the environmental protection responsibility to a higher level of government would be beneficial in terms of controlling pollution in China. | Huihui Deng Xinye Zheng Nan Huang Fanghua Li | 2012 | China & World Economy2012，20，5： | 33 |
| 4 | Fecal microbiota transplantation prevents hepatic encephalopathy in rats with carbon tetrachloride-induced acute hepatic dysfunction显示文摘AIM To investigate whether fecal microbiota transplantation(FMT) prevents hepatic encephalopathy(HE) in rats with carbon tetrachloride(CCl4)-induced acute hepatic dysfunction.METHODS A rat model of HE was established with CCl4. Rat behaviors and spatial learning capability were observed, and hepatic necrosis, intestinal mucosal barrier, serum ammonia levels and intestinal permeability were determined in HE rats receiving FMT treatment. Furthermore, the expression of tight junction proteins(Claudin-1, Claudin-6 and Occludin), Toll-like receptor(TLR) 4/TLR9, interleukin(IL)-1β, IL-6 and tumor necrosis factor(TNF)-α was examined.RESULTS FMT improved rat behaviors, HE grade and spatial learning capability. Moreover, FMT prevented hepaticnecrosis and intestinal mucosal barrier damage, leading to hepatic clearance of serum ammonia levels and reduced intestinal permeability. The expression of TLR4 and TLR9, two potent mediators of inflammatory response, was significantly downregulated in the liver of rats treated with FMT. Consistently, circulating proinflammatory factors such as interleukin(IL)-1β, IL-6 and tumor necrosis factor-α were remarkably decreased, indicating that FMT is able to limit systemic inflammation by decreasing the expression of TLR4 and TLR9. Importantly, HE-induced loss of tight junction proteins(Claudin-1, Claudin-6 and Occludin) was restored in intestinal tissues of rats receiving FMT treatment. CONCLUSION FMT enables protective effects in HE rats, and it improves the cognitive function and reduces the liver function indexes. FMT may cure HE by altering the intestinal permeability and improving the TLR response of the liver. | wei-wei wang yu zhang xiao-bing huang nan you lu zheng jing li | 2017 | World Journal of Gastroenterology2017，23，38： | 34 |
| 5 | Integrated assessment of river health based on water quality, aquatic life and physical habitat显示文摘The health conditions of Liao River were assessed using 25 sampling sites in April 2005, with water quality index, biotic index and physical habitat quality index. Based on the method of cluster analysis (CA) for water quality indices, it revealed that heavily polluted sites of Liao River are located at estuary and mainstream. The aquatic species surveyed were attached algae and benthic invertebrates. The result showed that the diversity and biomass of attached algae and benthic index of biotic integrity (B-IBI) were degrading as the chemical and physical quality of water bodies deteriorating. Physiochemical parameters, BOD5, CODCr, TN, TP, NH3-N, DO, petroleum hydrocarbon and conductivity, were statistically analyzed with principal component analysis and correlation analysis. The statistical results were incorporated into the integrated assessing water quality index, combining fecal coliform count, attached algae diversity, B-IBI and physical habitat quality score. A comprehensive integrated assessing system of river ecological health was established. Based on the systimetic assessment, the assessed sites are categorized into 9 'healthy' and 'sub-healthy' sites and 8 'sub-sick' and 'sick' sites. | MENG Wei ZHANG Nan ZHANG Yuan ZHENG Binghui | 2009 | Journal of Environmental Sciences2009，21，8： | 29 |

| 7 | Review of Rhubarbs: Chemistry and Pharmacology显示文摘Rhubarb is a perennial herb belonging to the genus Rheum L. (Polygonaceae). Rhei Radix et Rhizoma (rhubarb roots and rhizomes) is one of the most popular Chinese materia medica and has been widely used for strong laxative function. About 200 compounds with six different types of skeletons (anthraquinone, anthrone, stilbene, flavonoids, acylglucoside, and pyrone) have so far been isolated from eighteen species of the genus Rheum L. These constituents showed extensive pharmacological activities including cathartic, diuretic, anticancer, hepatoprotective, anti-inflammatory, and analgesic effects, as well as toxicological effects. Chemical fingerprint, LC-MS, and other analytical techniques have been used for the quality control of rhubarb. This comprehensive review summarizes the researches into the isolation, pharmacological activities, and phytochemical analysis reported since investigations began in the late 1940s. In addition, pharmacokinetic studies and clinical application of rhubarb are also discussed in present paper. | ZHENG Qing-xia WU Hai-feng GUO Jian NAN Hai-jiang CHEN Shi-lin YANG Jun-shan XU Xu-dong | 2013 | Chinese Herbal Medicines2013，5，1： | 26 |
| 8 | Parallel Learning:a Perspective and a Framework显示文摘The development of machine learning in complex system is hindered by two problems nowadays.The first problem is the inefficiency of exploration in state and action space,which leads to the data-hungry of some state-of-art data-driven algorithm.The second problem is the lack of a general theory which can be used to analyze and implement a complex learning system.In this paper,we proposed a general methods that can address both two issues.We combine the concepts of descriptive learning,predictive learning,and prescriptive learning into a uniform framework,so as to build a parallel system allowing learning system improved by self-boosting.Formulating a new perspective of data,knowledge and action,we provide a new methodology called parallel learning to design machine learning system for real-world problems. | Li Li Yilun Lin Nanning Zheng Fei-Yue Wang | 2017 | IEEE/CAA Journal of Automatica Sinica2017，4，3： | 25 |
| 9 | Indoor Allergen Levels and Household Distributions in Nine Cities Across China显示文摘Objective Chinese allergic subjects have high levels of sensitization to house dust mite(HDM) and other indoor allergens. This study quantifies common indoor allergen levels in Chinese households. Methods Dust samples were collected from nine cities. Major allergens Der p 1 and Der f 1 from Dermatophagoides pteronyssinus and D. farinae, and specific antigens of Blomia tropicalis, Tyrophagus putrescentiae, Acarus siro, and cockroach species Blattella germanica and Periplaneta americana were measured by ELISA. Results HDM allergens were found in dust samples from bedding in 95% of the Chinese households. The median levels varied from <0.006 to 9.2 μg/g of dust, depending on the city. The percentages of households having HDM allergen levels associated with the risk of developing allergy sensitization and asthma were 65% and 25%, respectively. Specific antigens of the storage mite and cockroach were only found in samples from the southern and tropical regions of China. Levels of mite allergens were generally higher in samples from bedding compared to samples from the living room, even for storage mites, whereas levels of cockroach antigens were higher in the living room samples. Conclusion HDM allergens are present in bedding dust samples from most Chinese households. Cities in southern and central China have relatively high levels of HDM major allergens compared to cities in northern and western China. Antigens of storage mites and cockroaches are not as common as HDM allergens. | ZHENG Yi Wu LAI Xu Xin ZHAO De Yu ZHANG Chun Qing CHEN Jian Jun ZHANG Luo WEI Qing Yu CHEN Shi LIU En Mei NORBACK Dan GJESING Birgitte ZHONG Nan Shan SPANGFORT D.Michael | 2015 | Biomedical and Environmental Sciences2015，28，10： | 24 |
| 10 | The FTO/miR-181b-3p/ARL5B signaling pathway regulates cell migration and invasion in breast cancer显示文摘Background:N6-methyladenosine(m6A)RNA modification has been demonstrated to be a significant regulatory process in the progression of various tumors,including breast cancer.Fat mass and obesity-associated(FTO)enzyme,initially known as the obesity-related protein,is the first identified m6A demethylase.However,the relationship between FTO and breast cancer remains controversial.In this study,we aimed to elucidate the role and clinical significance of FTO in breast cancer and to explore the underlying mechanism.Methods:We first investigated the expression of FTO in breast cancer cell lines and tissues by quantitative reverse transcription-PCR(qRT-PCR),Western blotting,and immunohistochemistry.Wound healing assay and Transwell assay were performed to determine the migration and invasion abilities of SKBR3 and MDAMB453 cells with either knockdown or overexpression of FTO.RNA sequencing(RNA-seq)was conducted to decipher the downstream targets of FTO.qRT-PCR,luciferase reporter assay,and Western blotting were employed to confirm the existence of the FTO/miR-181b-3p/ARL5B axis.The biological function of ADP ribosylation factor like GTPase 5B(ARL5B)in breast cancer cells was evaluated by wound healing assay and Transwell invasion assay.Results:High FTO expression was observed in human epidermal growth factor receptor 2(HER2)-positive breast cancer,predicting advanced progression(tumor size[P<0.001],nuclear grade[P=0.001],peritumoral lymphovascular invasion[P<0.001),lymph node metastasis[P=0.002],and TNM stage[P=0.001])and poor prognosis.Moreover,FTO promoted cell invasion and migration in vitro.Mechanistically,RNA-seq and further confirmation studies suggested that FTO up-regulated ARL5B by inhibiting miR-181b-3p.We further verified that ARL5B also displayed carcinogenic activity in breast cancer cells.Conclusion:Our work demonstrated the carcinogenic activity of FTO in promoting the invasion and migration of breast cancer cells via the FTO/miR-181b-3p/ARL5B signaling pathway. | Yuanyuan Xu Shuang Ye Nan Zhang Shuhui Zheng Huatao Liu Kewen Zhou Ling Wang Yue Cao Peng Sun Tinghuai Wang | 2020 | Cancer Communications2020，40，10： | 24 |

| 13 | Coastal acidification in summer bottom oxygen-depleted waters in northwestern-northern Bohai Sea from June to August in 2011显示文摘Dissolved oxygen(DO) and pH in the central part of the Bohai Sea were surveyed in late June and late August,2011.During the June cruise,the bottom DO was in the range of 215-290 μmol-O2 kg-1(i.e.85%-115% of the saturation level),and the bottom pH was in the range of 7.82-8.04 on the total-hydrogen-ion scale.In August,however,both the bottom DO and the pH had significantly declined in the northwestern-northern near-shore areas,where the water depth was no more than 35 m.The lowest bottom DO was 100-110 μmol-O2 kg-1(only 44%-47% of the June DO values) in the northern near-shore area,where the bottom pH was 7.64-7.68 on the total-hydrogen-ion scale(0.16-0.20 units lower than the June pH value).The largest decreases in DO and in pH were observed in the northwestern near-shore bottom waters,corresponding to declines of 170 μmol-O2 kg-1(as high as 59% of the June DO value) and 0.29 pH units,respectively.The greatest pH decline of 0.29 pH units meant that the total-hydrogen-ion concentration doubled in the bottom waters from June to August.Based on field measurements of bottom DO/pH combined with a simplified model simulation,we suggest that respiration/remineralization-derived CO2 increased the acidity in the bottom oxygen-depleted waters of northwestern-northern near-shore areas in the Bohai Sea as a result of coastal red tides and/or marine aquaculture.This aquatic chemistry is suggested to be partially responsible for scallop-breeding failures in the northwestern Bohai Sea in summer 2011. | ZHAI WeiDong ZHAO HuaDe ZHENG Nan XU Yi | 2012 | Chinese Science Bulletin2012，57，9： | 22 |
| 14 | Evaluation of the 7^(th) edition of the TNM classification in patients with resected esophageal squamous cell carcinoma显示文摘AIM:To evaluate the prognostic factors and tumor stages of the 7th edition TNM classification for esophageal cancer.METHODS:In total,1033 patients with esophageal squamous cell carcinoma(ESCC)who underwent surgical resection with or without(neo)adjuvant therapy between January 2003 and June 2012 at the Thoracic Surgery DepartmentⅡof the Beijing Cancer Hospital,Beijing,China were included in this study.The following eligibility criteria were applied:(1)squamous cell carcinoma of the esophagus or gastroesophageal junction identified by histopathological examination;(2)treatment with esophagectomy plus lymphadenectomy with curative intent;and(3)complete pathologic reports and follow-up data.Patients who underwent non-curative(R1)resection and patients who died in hospital were excluded.Patients who received(neo)adjuvant therapy were also included in thisanalysis.All patients were restaged using the 7th edition of the Union for International Cancer Control and the American Joint Committee on Cancer TNM staging systems.Univariate and multivariate analyses were performed to identify the prognostic factors for survival.Survival curves were plotted using the Kaplan-Meier method,and the log-rank test was used to evaluate differences between the subgroups.RESULTS:Of the 1033 patients,273 patients received(neo)adjuvant therapy,and 760 patients were treated with surgery alone.The median follow-up time was 51.6mo(range:5-112 mo)and the overall 5-year survival rate was 36.4%.Gender,'p T'and'p N'descriptors,(neo)adjuvant therapy,and the 7th edition TNM stage grouping were independent prognostic factors in the univariate and multivariate analyses.However,neither histologic grade nor cancer location were independent prognostic factors in the univariate and multivariate analyses.The 5-year stage-based survival rates were as follows:ⅠA,84.9%;ⅠB,70.9%;ⅡA,56.2%;ⅡB,43.3%;ⅢA,37.9%;ⅢB,23.3%;ⅢC,12.9%andⅣ,3.4%.There were significant differences between each adjacent staging classification.Moreover,there were significant differences between each adjacent p N and p M subgroup.According to the p T descriptor,there were significant differences between each adjacent subgroup except between p T3 and p T4(P=0.405).However,there was no significant difference between each adjacent histologic grade subgroup and between each adjacent cancer location subgroup.CONCLUSION:The 7th edition is considered to be valid for patients with resected ESCC.However,the histologic grade and cancer location were not prognostic factors for ESCC. | Jia Wang Nan Wu Qing-Feng Zheng Shi Yan Chao Lv Shao-Lei Li Yue Yang | 2014 | World Journal of Gastroenterology2014，20，48： | 23 |
| 15 | Nonnegative matrix factorization and its applications in pattern recognition显示文摘Matrix factorization is an effective tool for large-scale data processing and analysis. Non- negative matrix factorization (NMF) method, which decomposes the nonnegative matrix into two non- negative factor matrices, provides a new way for ma- trix factorization. NMF is significant in intelligent information processing and pattern recognition. This paper firstly introduces the basic idea of NMF and some new relevant methods. Then we discuss the loss functions and relevant algorithms of NMF in the framework of probabilistic models based on our re- searches, and the relationship between NMF and information processing of perceptual process. Finally, we make use of NMF to deal with some practical questions of pattern recognition and point out some open problems for NMF. | LlU Weixiang ZHENG Nanning YOU Qubo | 2006 | Chinese Science Bulletin2006，51，1： | 21 |

| 17 | Modeling and stabilization for a class of nonlinear networked control systems: A T-S fuzzy approach显示文摘The stabilization problem for a class of nonlinear networked control systems (NCSs) is investigated in this paper. A Takagi-Sugeno (T-S) fuzzy model is employed to represent the nonlinear controlled plant in the NCSs. Based on parallel distributed compensation (PDC) technique, a novel model of the nonlinear NCSs is established firstly in consideration of both network-induced delay and packet losses in transmission. Then a stability condition of the nonlinear NCSs is presented in terms of linear matrix inequalities (LMIs) by using the Lyapunov-Krasovskii functional method and the delay input approach. Furthermore, the control design of the nonlinear NCSs is developed by means of LMIs. Finally, a numerical example is given to demonstrate the effectiveness of the proposed method. | Xinchun Jia Dawei Zhang Lihong Zheng Nanning Zheng | 2008 | Progress in Natural Science:Materials International2008，18，8： | 14 |

| 19 | Prognosis of microscopic polyangiitis with renal involvement:report of 60 Chinese patients显示文摘With the widespread clinical application of renal biopsy and serum antineutrophil cytoplasmic antibody (ANCA) testing, the percentage of renal injuries caused by systemic small vessel vasculitis (SVV) including microscopic polyangiitis (MPA) and Wegener’ s granulomatosis (WG) is on the rise in China. According to our previous report, SVV constituted 1.09% of diagnoses from all renal biopsies (5. 8% in secondary nephritis) and 14. 4% of that from renal biopsies from patients with chronic renal,failure, among which MPA is the most common type. Many studies reported that SVV with rapid progressive glomerulonephritis had poor prognosis with a 5-year renal survival less than 75%. However, there is a lack of large-sample statistical analysis about the long-term prognosis of SVV in China. Indeed, the clinical manifestations of SVV in China are quite different from those reported in other countries. This study is a retrospective analysis of the long term patient and renal survival rate and contributing factors based on 60 cases of MPA. | HU Wei-xin, LIU Zhi-hong,LIU Chun-bei,TANG Zheng, WANG Qing-wen, CHEN Hui-ping and LI Lei-shi Department of Nephrology, Clinical School of Nan jing, Second Military Medical University Research Institute of Nephrology, Jinling Hospital, Nanjing 210002, China | 2005 | Chinese Medical Journal2005，，24： | 12 |
