| 1 | Review of Key Problems Related to Integrated Energy Distribution Systems显示文摘Integrated energy distribution system(IEDS)is one of the integrated energy and power system forms,which involves electricity/gas/cold/heat and other various energy forms.The energy coupling relationship is close and complex.IEDS is the focus of regional energy internet research and development at home and abroad.Compared with the traditional power distribution system,IEDS through the multi-energy coupling link comprehensive utilization,effectively improve the distribution system economy,safety,reliability,flexibility and toughness,but also to ease the regional energy system environmental pressure.IEDS is an important direction for the future development of energy systems,and its related research and practice on China’s energy system development also has important practical and strategic significance.This paper summarizes the related researches of the IEDS and explores the energy operation characteristics and coupling mechanisms.What’s more,the integrated model of IEDS is summarized.On these bases,this paper discusses and prospects some key issues such as joint planning,optimization control and security analysis,state estimation and situational awareness and generalized demand side management. | Dan Wang Liu Liu Hongjie Jia Weiliang Wang Yunqiang Zhi Zhengji Meng Bingyu Zhou | 2018 | CSEE Journal of Power and Energy Systems2018，4，2： | 43 |
| 2 | Modulatory effects of acupuncture on brain networks in mild cognitive impairment patients显示文摘Functional magnetic resonance imaging has been widely used to investigate the effects of acupuncture on neural activity. However, most functional magnetic resonance imaging studies have focused on acute changes in brain activation induced by acupuncture. Thus, the time course of the therapeutic effects of acupuncture remains unclear. In this study, 32 patients with amnestic mild cognitive impairment were randomly divided into two groups, where they received either Tiaoshen Yizhi acupuncture or sham acupoint acupuncture. The needles were either twirled at Tiaoshen Yizhi acupoints, including Sishencong(EX-HN1), Yintang(EX-HN3), Neiguan(PC6), Taixi(KI3), Fenglong(ST40), and Taichong(LR3), or at related sham acupoints at a depth of approximately 15 mm, an angle of ± 60°, and a rate of approximately 120 times per minute. Acupuncture was conducted for 4 consecutive weeks, five times per week, on weekdays. Resting-state functional magnetic resonance imaging indicated that connections between cognition-related regions such as the insula, dorsolateral prefrontal cortex, hippocampus, thalamus, inferior parietal lobule, and anterior cingulate cortex increased after acupuncture at Tiaoshen Yizhi acupoints. The insula, dorsolateral prefrontal cortex, and hippocampus acted as central brain hubs. Patients in the Tiaoshen Yizhi group exhibited improved cognitive performance after acupuncture. In the sham acupoint acupuncture group, connections between brain regions were dispersed, and we found no differences in cognitive function following the treatment. These results indicate that acupuncture at Tiaoshen Yizhi acupoints can regulate brain networks by increasing connectivity between cognition-related regions, thereby improving cognitive function in patients with mild cognitive impairment. | Ting-ting Tan Dan Wang Ju-ke Huang Xiao-mei Zhou Xu Yuan Jiu-ping Liang Liang Yin Hong-liang Xie Xin-yan Jia Jiao Shi Fang Wang Hao-bo Yang Shang-jie Chen | 2017 | Neural Regeneration Research2017，12，2： | 32 |

| 5 | Active power regulation of wind power systems through demand response显示文摘With the specific characteristics of low-carbon intensity and economy,wind power has been widely promoted around the world.Due to the variable and intermittent nature of wind power production,the system has to frequently redispatch generators in order to ensure the effective use of wind power whilst maintaining system security.In this way,traditional generation costs are increased and the social benefit of wind power decreases indirectly.In this paper,a new regulation strategy based on power flow tracing was proposed,taking advantage of a comfort-constrained demand response strategy to follow the fluctuations of wind farm output,with the remaining imbalance of active power compensated by traditional generators.Examples showed that compared with conventional regulation,demand response could reduce the gross operating costs of the system,and the rapid response could help maintaining system stability in case of contingency.The strategy in this paper also applies to other large-scale integration problems associated with renewable energy resources which display short-term production variability. | MIAO WeiWei JIA HongJie WANG Dan PARKINSON Simon CRAWFORD Curran DJILALI Ned | 2012 | Science China(Technological Sciences)2012，55，6： | 24 |
| 6 | Acupuncture at the Taixi(KI3) acupoint activates cerebral neurons in elderly patients with mild cognitive impairment显示文摘Our previous findings have demonstrated that acupuncture at the Taixi(KI3) acupoint in healthy youths can activate neurons in cognitive-related cerebral cortex. Here, we investigated whether acupuncture at this acupoint in elderly patients with mild cognitive impairment can also activate neurons in these regions. Resting state and task-related functional magnetic resonance imaging showed that the pinprick senstation of acupuncture at the Taixi acupoint differed significantly between elderly patients with mild cognitive impairment and healthy elderly controls. Results showed that 20 brain regions were activated in both groups of participants, including the bilateral anterior cingulate gyrus(Brodmann areas [BA] 32, 24), left medial frontal cortex(BA 9, 10, 11), left cuneus(BA 19), left middle frontal gyrus(BA 11), left lingual gyrus(BA 18), right medial frontal gyrus(BA 11), bilateral inferior frontal gyrus(BA 47), left superior frontal gyrus(BA11), right cuneus(BA 19, 18), right superior temporal gyrus(BA 38), left subcallosal gyrus(BA 47), bilateral precuneus(BA 19), right medial frontal gyrus(BA 10), right superior frontal(BA 11), left cingulate gyrus(BA 32), left precentral gyrus(BA 6), and right fusiform gyrus(BA 19). These results suggest that acupuncture at the Taixi acupoint in elderly patients with mild cognitive impairment can also activate some brain regions. | Shangjie Chen Maosheng Xu Hong Li Jiuping Liang Liang Yin Xia Liu Xinyan Jia Fen Zhu Dan Wang Xuemin Shi Lihua Zhao | 2014 | Neural Regeneration Research2014，9，11： | 18 |
| 7 | Dynamic recrystallization behavior of GH4169G alloy during hot compressive deformation显示文摘The microstructure evolutions and nucleation mechanisms of GH4169G alloy were studied by optical microscope, electron backscatter diffraction (EBSD) and transmission electron microscope (TEM). The hot compression tests were performed different imposed reductions in the range of true strain from 0.12 to 1.2 at the temperatures of 930 °-1050 ° with strain rates of 0.01 s^-1-l s^-1. It is found that cumulative and local misorientation increase firstly and then decrease when the strain is increased due to the progress of dynamic recrystallization (DRX). The low angle boundaries (LAGBs) rapidly develop to high angle boundaries (HAGBs) at relatively high deformation temperature or the low strain rate. There are three DRX mechanisms observed for GH4169 G alloy during hot deformation. Discontinuous dynamic recrystallization (DDRX) as the dominant mechanism for GH4169 G alloy is characterized by typical necklace structures and bulged-original boundaries. Besides, different deformation bands with dislocation cells formed in deformed matrix at low temperature and large strain, which indicates that continuous dynamic recrystallization (CDRX) contributed to the DRX process. The twin boundaries lost their coherent characteristics and provide sites for nucleation, which also accelerates the nucleation of DRX. | Dan Jia Wenru Sun Dongsheng Xu Fang Liu | 2019 | Journal of Materials Science & Technology2019，35，9： | 13 |

| 9 | Chinese herbal medicine reduces mortality in patients with severe and critical coronavirus disease 2019: a retrospective cohort study显示文摘This study aimed to evaluate the efficacy of Chinese herbal medicine(CHM)in patients with severe/critical coronavirus disease 2019(COVID-19).In this retrospective study,data were collected from 662 patients with severe/critical COVID-19 who were admitted to a designated hospital to treat patients with severe COVID-19 in Wuhan before March 20,2020.All patients were divided into an exposed group(CHM users)and a control group(non-users).After propensity score matching in a 1:1 ratio,156 CHM users were matched by propensity score to 156 non-users.No significant differences in seven baseline clinical variables were found between the two groups of patients.All-cause mortality was reported in 13 CHM users who died and 36 non-users who died.After multivariate adjustment,the mortality risk of CHM users was reduced by 82.2%(odds ratio 0.178,95%CI 0.076–0.418;P<0.001)compared with the non-users.Secondly,age(odds ratio 1.053,95%CI 1.023–1.084;P<0.001)and the proportion of severe/critical patients(odds ratio 0.063,95%CI 0.028–0.143;P<0.001)were the risk factors of mortality.These results show that the use of CHM may reduce the mortality of patients with severe/critical COVID-19. | Guohua Chen Wen Su Jiayao Yang Dan Luo Ping Xia Wen Jia Xiuyang Li Chuan Wang Suping Lang Qingbin Meng Ying Zhang Yuhe Ke An Fan Shuo Yang Yujiao Zheng Xuepeng Fan Jie Qiao Fengmei Lian Li Wei Xiaolin Tong | 2020 | Frontiers of Medicine2020，14，6： | 10 |
| 10 | Effect of Intermetallic Phases on Corrosion Initiation of AZ91 Alloy With Rare Earth Y Addition显示文摘The effect of the rare earth(RE) element Y on the microstructure of AZ91 Mg alloy is investigated.A detailed description of the procedure of identifying the intermetallic phases containing Y in the AZ91 Mg alloy with 0.9 wt%Y addition is presented.The results shows that there are two different kinds of RE phases in scanning electron microscopy(SEM) images.Energy dispersive spectrum(EDS) analysis shows that one is rich in Y element and the other is rich in Mn element.According to the element mapping of electron probe microanalysis(EPMA).the element Al can be found not only in the β-Mg_(17)Al_(12) phase but also in these two RE phases.X-ray diffraction(XRD) and transmission electron microscopy(TEM) results further confirm one of the two RE phases is AI2Y;the phase of Al_(10)Mn_2Y has just been determined by transmission electron microscopy(TEM) instead of XRD probably because it is scarce.The shapes of these two RE intermetallic phases are pretty similar.The 3D digital microscopy is employed to observe in-situ the effect of the(5 phase and the above two RE intermetallic phases on the corrosion initiation of the alloys.The results show that the corrosion attack of AZ91 Mg alloy without Y addition starts around the eutectic phase β-Mg_(17)Al_(12).With the addition of 0.9 wt%Y,the two kinds of Y-rich intermetallic phases act as cathodic effect and a phase in the adjacent of them was activated and cathodic effect of the β-Mg_(17)Al_(12)phase was inhibited. | Li-na Zhang Ruiling Jia Dan Li Wei Zhang Feng Guo | 2015 | Journal of Materials Science & Technology2015，31，5： | 8 |
| 11 | The role of FGF21 in the pathogenesis of cardiovascular disease显示文摘The morbidity and mortality of cardiovascular diseases(CVDs)are increasing worldwide and seriously threaten human life and health.Fibroblast growth factor 21(FGF21),a metabolic regulator,regulates glucose and lipid metabolism and may exert beneficial effects on the cardiovascular system.In recent years,FGF21 has been found to act directly on the cardiovascular system and may be used as an early biomarker of CVDs.The present review highlights the recent progress in understanding the relationship between FGF21 and CVDs including coronary heart disease,myocardial ischemia,cardiomyopathy,and heart failure and also explores the related mechanism of the cardioprotective effect of FGF21.FGF21 plays an important role in the prediction,treatment,and improvement of prognosis in CVDs.This cardioprotective effect of FGF21 may be achieved by preventing endothelial dysfunction and lipid accumulating,inhibiting cardiomyocyte apoptosis and regulating the associated oxidative stress,inflammation and autophagy.In conclusion,FGF21 is a promising target for the treatment of CVDs,however,its clinical application requires further clarification of the precise role of FGF21 in CVDs. | Ying Zhang Dan Liu Xiao-Xue Long Qi-Chen Fang Wei-Ping Jia Hua-Ting Li | 2021 | Chinese Medical Journal2021，，24： | 8 |

| 13 | Central Obesity and Metabolic Risk Factors in Middle-aged Chinese显示文摘Objective Central obesity is considered to be a central component of metabolic syndrome. Waist circumference(WC) has been widely used as a simple indicator of central obesity. This study is aimed to evaluate the sensitivity of WC cut-off values for predicting metabolic risk factors in middle-aged Chinese. Methods The study involved 923 subjects aged 40-65 years. The metabolic risk factors were defined according to the Chinese Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults. WC cut-off 85-90 cm and ≥90 cm were used as cut-off values of central pre-obesity and central obesity in males, respectively, while WC 80-85 cm and ≥85 cm were used as cut-off values of central pre-obesity and central obesity in females. Results First, WC values corresponding to body mass index(BMI) 24 kg/m2 and visceral fat area(VFA) 80 cm2 were 88.55 cm and 88.51 cm in males, and 81.46 cm and 82.51 cm in females respectively. Second, receiver operating characteristic curves showed that the optimal WC cut-off of value was 88.75 cm in males, higher than that in females(81.75 cm). Third, the subjects with higher WC values were more likely to have accumulating metabolic risk factors. The prevalence of metabolic risk factors increased linearly and significantly in relation to WC levels. Conclusion WC cut-off values of central pre-/central obesity are optimal to predict multiple metabolic risk factors. | YIN Xue Yao ZHENG Fen Ping ZHOU Jia Qiang DU Ying PAN Qian Qian ZHANG Sai Fei YU Dan LI Hong | 2014 | Biomedical and Environmental Sciences2014，27，5： | 6 |
| 14 | The Association of Socioeconomic Status with the Burden of Cataract-related Blindness and the Effect of Ultraviolet Radiation Exposure: An Ecological Study显示文摘Objective To assess the association of socioeconomic status with the burden of cataract blindness in terms of year lived with disability(YLD) rates and to determine whether ultraviolet radiation(UVR) levels modify the effect of socioeconomic status on this health burden.Methods National and subnational age-standardized YLD rates associated with cataract-related blindness were derived from the Global Burden of Disease(GBD) study 2017. The human development index(HDI) from the Human Development Report was used as a measure of socioeconomic status.Estimated ground-level UVR exposure was obtained from the Ozone Monitoring Instrument(OMI)dataset of the National Aeronautics and Space Administration(NASA).Results Across 185 countries, socioeconomic status was inversely associated with the burden of cataract blindness. Countries with a very high HDI had an 84% lower age-standardized YLD rate [95%confidence interval(CI): 60%–93%, P < 0.001] than countries with a low HDI;for high-HDI countries, the proportion was 76%(95% CI: 53%–88%, P < 0.001), and for medium-HDI countries, the proportion was48%(95% CI: 15%–68%, P = 0.010;P for trend < 0.001). The interaction analysis showed that UVR exposure played an interactive role in the association between socioeconomic status and cataract blindness burden(P value for interaction = 0.047).Conclusion Long-term high-UVR exposure amplifies the association of poor socioeconomic status with the burden of cataract-related blindness. The findings emphasize the need for strengthening UVR exposure protection interventions in developing countries with high-UVR exposure. | DENG Yan YANG Dan YU Jia Ming XU Jing Xian HUA Hui CHEN Ren Tong WANG Nan OU Feng Rong LIU Ru Xi WU Bo LIU Yang | 2021 | Biomedical and Environmental Sciences2021，34，2： | 6 |

| 16 | Growth characteristics of algae during early stages of phytoplankton bloom in Lake Taihu,China显示文摘Three treatments, sediment plus lake water (S+W), sterilized sediment plus lake water (SS+W), and sediment plus filtered lake water (S+FW), were recruited to investigate the growth characteristics of algae during pre-bloom and the importance of algal inocula in the water column and sediment. The results showed that in the water column, biomass of all algae increased in all treatments when recruitment was initiated, whereas this tendency differed among treatments with further increment of temperature. The process of algal growth consisted of two stages: Stage I, the onset of recruitment and Stage II, the subsequent growth of algae. Compared with S+W, in Stage I, SS+W significantly increased the biomass of cyanophytes by 178.70%, and decreased the biomass of non-cyanophytes by 43.40%; In Stage II, SS+W notably stimulated the growth of all algae, thus incurring the occurrence of phytoplankton bloom. Further analyses revealed that both metabolic activity and photochemical activity of algae were enhanced in SS+W, which resulted from the releasing of nutrients from sediment. These results suggest that algal growth in Stage II and algal inocula in the water column can be important factors for the formation of phytoplankton bloom. In addition, possible mechanisms promoting algal recruitment and subsequent growth of algae were explored. | Yuhong Jia Johnson Dan Min Zhang Fanxiang Kong | 2013 | Journal of Environmental Sciences2013，25，2： | 6 |
| 17 | Uniform corrosion behavior of FeCrAl alloys in borated and lithiated high temperature water显示文摘The uniform corrosion behavior of model FeCrAl alloys as well as commercial Zircaloy-4 as reference material were investigated in 360℃borated and lithiated water.The results reveal that FeCrAl alloys exhibited better corrosion resistance than Zircaloy-4.It is found that the oxide films formed on the FeCrAl alloys are composed of outer Fe_(3)O_(4)layer,inner layer consisting of compact spinel layer and porous spinel layer,and transition layer containing Al-Cr-rich oxides and matrix enriched with Fe°.The spinel oxides in the inner layer are FeFe_(2-x-y-z)Cr_(x)Al_(y)MozO_(4).The corrosion mechanism of FeCrAl alloys in high temperature water is discussed. | Fangqiang Ning Xiang Wang Ying Yang Jibo Tan Ziyu Zhang Dan Jia Xinqiang Wu En-Hou Han | 2021 | Journal of Materials Science & Technology2021，，11： | 6 |
| 18 | Intelligent checking model of Chinese radiotelephony read-backs in civil aviation air traffic control显示文摘Federal Aviation Administration(FAA) and NASA technical reports indicate that the misunderstanding in radiotelephony communications is a primary causal factor associated with operation errors, and a sizable proportion of operation errors lead to read-back errors. We introduce deep learning method to solve this problem and propose a new semantic checking model based on Long Short-Time Memory network(LSTM) for intelligent read-back error checking. A meanpooling layer is added to the traditional LSTM, so as to utilize the information obtained by all the hidden activation vectors, and also to improve the robustness of the semantic vector extracted by LSTM. A MultiLayer Perceptron(MLP) layer, which can maintain the information of different regions in the concatenated vectors obtained by the mean-pooling layer, is applied instead of traditional similarity function in the new model to express the semantic similarity of the read-back pairs quantitatively. The K-Nearest Neighbor(KNN) classifier is used to verify whether the read-back pairs are consistent in semantics according to the output of MLP layer. Extensive experiments are conducted and the results show that the proposed model is more effective and more robust than the traditional checking model to verify the semantic consistency of read-backs automatically. | Guimin JIA Fangyuan CHENG Jinfeng YANG Dan LI | 2018 | Chinese Journal of Aeronautics2018，31，12： | 5 |
| 19 | Detection of phthalates migration from disposable tablewares to drinking water using hexafluoroisopropanol-induced catanionic surfactant coacervate extraction显示文摘Hexafluoroisopropanol(HFIP)-induced sodium dodecyl sulfate/dodecyltrimethylammonium bromide(SDS/DTAB) catanionic surfactant coacervate extraction method coupled with high performance liquid chromatography(HPLC) was used to detect the migration of phthalates from disposable tablewares to drinking water. The concentration factors are larger than 82 and extraction recoveries over 53% for water samples spiked with 100 or 200 ng/m L phthalates. Limit of detection is in the range of 1.0–2.6 ng/m L.Good linearity with correlation coefficients larger than 0.9985 is obtained in the concentration of20–1500 or 40–3000 ng/m L. Relative recoveries are from 82.4% to 123.6% for water samples spiked with30/60, 250/500, and 1500/3000 ng/m L phthalates, respectively. Relative standard deviations(RSDs) are0.4%–7.4% for intraday precision(n = 5) and 0.6%–7.8% for interday precision(n = 3). Four of studied phthalates are found in the drinking water samples prepared from four kinds of tablewares. | Cao Li Jia Xu Dan Chen Yuxiu Xiao | 2016 | Journal of Pharmaceutical Analysis2016，6，5： | 5 |
| 20 | Stannous-acetylacetonate:A new catalyst for poly(trimethylene terephthalate) synthesis显示文摘Stannous-acetylacetonate was prepared efficiently and characterized by 1H NMR and FT-IR. Its catalytic activity for poly(trimethylene terephthalate) (PTT) synthesis was investigated. By this catalyst, the degree of esterification of pure terephthalic acid was up to 91.7% after reaction at 260°C for 2 h, while the intrinsic viscosity and content of ter- minal carboxyl groups of the corresponding PTT polymerized at 260°C, 60 Pa for 2 h was 0.8816 dL/g and 17 mol/t, respectively. Stannous-acetylacetonate was more active and promising than tetrabutyl titanate and stannous octoate for PTT synthesis. | Shu Yong Jia Yu Rong Ren Liang Ming Liu Dan Zhang Yi Zeng Gong Ying Wang | 2007 | Chinese Chemical Letters2007，18，7： | 5 |
