1Advanced treatment of dyeing wastewater towards reuse by the combined Fenton oxidation and membrane bioreactor process显示文摘The performance of combined Fenton oxidation and membrane bioreactor (MBR) process for the advanced treatment of an effluent from an integrated dyeing wastewater treatment plant was evaluated. The experimental results revealed that under the optimum Fenton oxidation conditions (initial pH 5, H 2 O 2 dosage 17 mmol/L, and Fe 2+ 1.7 mmol/L) the average total organic carbon (TOC) and color removal ratios were 39.3% and 69.5% after 35 min of reaction, respectively. Results from Zahn-Wallens Test also represented that Fenton process was effective to enhance the biodegradability of the test wastewater. As for the further purification of MBR process, TOC removal capacity was examined at different hydraulic retention times (HRT) of 10, 18 and 25 hr. Under the optimum HRT of 18 hr, the average TOC concentration and color of the final MBR effluent were 16.8 mg/L and 2 dilution time, respectively. The sludge yield coefficient was 0.13 g MLSS/g TOC and TOC degradation rate was 0.078 kg TOC/(m 3 ·day). The final effluent of MBR can meet the reuse criteria of urban recycling water-water quality standard for miscellaneous water consumption GBT18920-2002.Fei Feng Zhenliang XU Xiaohuan Li Wenting You Yang Zhen 2010Journal of Environmental Sciences2010,22,11:27
2Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic.Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan 2020National Science Review2020,7,9:20
3Liver Enzymes Concentrations Are Closely Related to Pre-diabetes:Findings of the Shanghai Diabetes Study Ⅱ (SHDS Ⅱ)显示文摘Objective To investigate the relationship of liver enzymes with hyperglycemia in a large population in Shanghai and identify the association between liver enzymes and insulin resistance.Methods A total of 3 756 participants were enrolled.Each participant underwent an oral glucose tolerance test and completed a questionnaire.Anthropometric indices were recorded and serum samples were collected for measurement.Results Liver enzymes concentrations were independently associated with i-IGT,IFG+IGT,and diabetes.With the increase of ALT and GGT concentrations,ORs for i-IGT,IFG+IGT,and diabetes increased gradually.By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile (Q1),ORs for i-IGT,IFG+IGT,or diabetes was significant after adjustment.Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR (95% CI):2.56 (1.51-4.34) P=0.00;GGT OR (95% CI):2.66 (1.53-4.65) P=0.00].Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance.GAO Fei PAN Jie Min HOU Xu Hong FANG Qi Chen LU Hui Juan TANG Jun Ling GU Hui Lin PAN Zhi Jian YAO You Hua SHEN Wei Zhen JIA Wei Ping 2012Biomedical and Environmental Sciences2012,25,1:15
4Effects of warming and clipping on plant and soil properties of an alpine meadow in the Qinghai-Tibetan Plateau, China显示文摘Climate warming and livestock grazing are known to have great influences on alpine ecosystems like those of the Qinghai-Tibetan Plateau(QTP) in China. However, it is lacking of studies on the effects of warming and grazing on plant and soil properties in these alpine ecosystems. In this study, we reported the related research from manipulative experiment in 2010–2012 in the QTP. The aim of this study was to investigate the individual and combined effects of warming and clipping on plant and soil properties in the alpine meadow ecosystem. Infrared radiators were used to simulate climate warming starting in July 2010, while clipping was performed once in October 2011 to simulate the local livestock grazing. The experiment was designed as a randomized block consisting of five replications and four treatments: control(CK), warming(W), clipping(C) and warming+clipping combination(WC). The plant and soil properties were investigated in the growing season of the alpine meadow in 2012. The results showed that W and WC treatments significantly decreased relative humidity at 20-cm height above ground as well as significantly increases air temperature at the same height, surface temperature, and soil temperature at the depth of 0–30 cm. However, the C treatment did not significantly decrease soil moisture and soil temperature at the depth of 0–60 cm. Relative to CK, vegetation height and species number increased significantly in W and WC treatment, respectively, while vegetation aboveground biomass decreased significantly in C treatment in the early growing season. However, vegetation cover, species diversity, belowground biomass and soil properties at the depth of 0–30 cm did not differ significantly in W, C and WC treatments. Soil moisture increased at the depth of 40–100 cm in W and WC treatments, while belowground biomass, soil activated carbon, organic carbon and total nitrogen increased in the 30–50 cm soil layer in W, C and WC treatments. Although the initial responses of plant and soil properties to experimental warming and clipping were slow and weak, the drought induced by the downward shift of soil moisture in the upper soil layers may induce plant belowground biomass to transfer to the deeper soil layers. This movement would modify the distributions of soil activated carbon, organic carbon and total nitrogen. However, long-term data collection is needed to further explain this interesting phenomenon.Man Hou XU Fei PENG Quan Gang YOU Jian GUO Xia Fei TIAN Min LIU Xian XUE 2015Journal of Arid Land2015,7,2:14
5An energy minimization algorithm based on distributed dynamic clustering for long term evolution(LTE) heterogeneous networks显示文摘Energy saving has become an important issue in wireless communications from both environment and economic considerations. In this paper, an energy minimization algorithm based on distributed dynamic clustering(DDCEM) with lower complexity, higher performance, and better adaptability for heterogeneous network(Het Net) is proposed. A Het Net could be divided into several clusters, which is defined as one group of a network node and users served by the node. A energy efficient user association, which dynamically changes according to real-time energy efficiency(EE) evaluation with traffic load and location distribution of each cluster, can be employed to save consumed energy. Then, the optimal sleeping relay is found as follows. First,the sleeping probability cost of each relay station(RS) is computed and ranked based on the user traffic and the position distribution of each cluster, and the relay with minimum sleeping probability is selected to be switched off. Hence, the sleep node is selected taking into account the traffic load and location of the Evolved Node B(e NB) and all the RSs. The complexity of the algorithm is greatly reduced because the user association operation and network load evaluation are fulfilled cluster by cluster. Simulation results show that the proposed DDCEM strategy offers EE gain with low system complexity.TONG En DING Fei PAN ZhiWen YOU Xiao Hu 2015Science China(Information Sciences)2015,58,4:13

7Wrist-ankle acupuncture and Fluoxetine in the treatment of post-stroke depression: a randomized controlled clinical trial显示文摘OBJECTIVE: To investigate the effects of WAA combined with fluoxetine in the clinical treatment of post-stroke depression(PSD).METHODS: In this randomized, controlled and single-blind trial, 105 PSD patients who met the inclusion criteria were randomly divided into three equal groups: Thin wrist-ankle acupuncture(WAA)group(Thin WAA needle + Fluoxetine), Thick WAA group(Thick WAA needle + Fluoxetine), and Sham WAA group(sham WAA needle + Fluoxetine). In this trial, the primary outcome was Hamilton Depression Scale(HAMD), while the secondary outcomes included Zung self-rating depression scale(SDS) and World Health Organization Quality of Life BREF(QQL).RESULTS: Ninety nine PSD patients completed all the treatment. The HAMD scores and SDS scores of all the three groups decreased after treatment(P <0.05);thick WAA group and thin WAA group decreased more obviously than the sham WAA group(P < 0.05). There was no significant difference between the QQL scores of the three groups(P >0.05). There was no significant difference in the scores of the three scales between the thick wrist ankle needles and the thin wrist ankle needles(P >0.05).CONCLUSION: The present study showed that WAA combined with fluoxetine can relieve the symptoms of depression after stroke. WAA therapy could improve the antidepressant effect of fluoxetine.You Yanli Zhang Tianfang Shu Shi Qian Xiaolu Zhou Shuang Yao Fei 2020Journal of Traditional Chinese Medicine2020,40,3:10

9CuFe2O4@GO nanocomposite as an effective and recoverable catalyst of peroxymonosulfate activation for degradation of aqueous dye pollutants显示文摘Recently,heterogeneous activation of peroxymonosulfate(PMS) to oxidatively degrade organic pollutants has been a hotspot.In the present work,copper ferrite-graphite oxide hybrid(CuFe2 O4@GO)was prepared and used as catalyst to activate PMS for degradation of methylene blue(MB) in aqueous solution.A high degradation efficiency(93.3%) was achieved at the experimental conditions of20 mg/L MB,200 mg/L CuFe2 O4@GO,0.8 mmol/L PMS,and 25℃temperature.Moreover,CuFe2 O4@GO showed an excellent reusability and stability.The effects of various operational parameters including pollutant type,solution pH,catalyst dosage,PMS dosage,pollutant concentration,temperature,natural organic matter(NOM),and inorganic anions on the catalytic degradation process were comprehensively investigated and elucidated.The further mechanistic study revealed the Cu(Ⅱ)/Cu(Ⅰ) redox couple on CuFe2 O4@GO played the dominant role in PMS activation,where both hydroxyl and sulfate radicals were generated and proceeded the degradation of pollutants.In general,CuFe2 O4@GO is a promising heterocatalyst for PMS-based advanced oxidation processes(AOPs) in wastewater treatment.Xiaoman Lei Menghan You Fei Pan Min Liu Peng Yang Dongsheng Xia Qiang Li Yanting Wang Jie Fu 2019Chinese Chemical Letters2019,30,12:8

11System modeling based measurement error analysis of digital sun sensors显示文摘Stringent attitude determination accuracy is required for the development of the advanced space technologies and thus the accuracy improvement of digital sun sensors is necessary.In this paper,we presented a proposal for measurement error analysis of a digital sun sensor.A system modeling including three different error sources was built and employed for system error analysis.Numerical simulations were also conducted to study the measurement error introduced by different sources of error.Based on our model and study,the system errors from different error sources are coupled and the system calibration should be elaborately designed to realize a digital sun sensor with extra-high accuracy.WEI M insong XING Fei WANG Geng YOU Zheng 2015Instrumentation2015,2,1:7
12Study of high-precision earth sensor with triple-FOV显示文摘Earth sensors are widely used in spacecraft for attitude determination. They need to have a very large field of view(FOV)( > 120°) and relatively low accuracy while being used in the aircrafts around orbit. A triple-FOV infrared earth sensor is proposed in this paper. It uses three pieces of standard infrared detectors with a wavelength range of 14;16μm,to sense the horizontal circle by detecting the infrared light emitted from the earth. From which,the geocentric vector can be obtained. A mathematic model is established and a validation model is set up to provide input parameters for the mathematic model. The simulation results of the two models show that the output of the mathematic model coincides with the known parameters. Based on the above analysis,a prototype has been built and tested. The test results show that the angle measurement error is about 0. 002° and hence such a triple-FOV earth sensor is capable to provide high-precision position information for autonomous navigation.WANG Hongjian XING Fei YOU Zheng CHU Daping ZHENG Lungui 2014Instrumentation2014,1,2:6

14Two case reports and literature review for hepatic epithelioid angiomyolipoma: Pitfall of misdiagnosis显示文摘BACKGROUND Hepatic epithelioid angiomyolipoma(HEAML) is a rare liver disease and is easily misdiagnosed. Enhanced recognition of HEAML is beneficial to the differential diagnosis of rare liver diseases.CASE SUMMARY We presented two cases of HEAML in Changzheng Hospital, Naval Medical University, and then collected and analyzed all reports about HEAML recorded in PubMed, MEDLINE, China Science Periodical Database, and VIP database from January 2000 to March 2018. A total of 409 cases of HEAML in 97 reports were collected, with a ratio of men to women of 1:4.84 and an age range from 12 years to 80 years(median 44 years). Among the patients with clinical symptoms mentioned, 61.93%(205/331) were asymptomatic, 34.74%(115/331) showed upper or right upper quadrant abdomen discomfort, while a few of them showed abdominal mass, gastrointestinal symptoms, low fever, or weight loss. The misdiagnosis rate of HEAML was as high as 40.34%(165/409) due to its nonspecific imaging findings. Most of the tumors were solitary and round in morphology, with clear boundaries. Ultrasound scan indicated low echo with internal nonuniformity and rich blood supply in most cases. Computer tomography/magnetic resonance imaging enhanced scan showed varied characteristics. The ratio of fast wash-in and fast wash-out, fast wash-in and slow wash-out, and delayed enhancement was roughly 4:5:1. A definite diagnosis of HEAML depended on the pathological findings of the epithelioid cells in lesions and the expression of human melanoma black 45, smooth muscle actin,melanoma antigen, and actin by immunohistochemical staining. HEAML had a relatively low malignant rate of 3.91%. However, surgical resection was the main treatment for HEAML, due to the difficulty diagnosing before operation.CONCLUSION HEAML is a rare and easily misdiagnosed disease, and it should be diagnosed carefully, taking into account clinical course, imaging, pathological,and immunohistochemical findings.Jia-Xi Mao Fei Teng Cong Liu Hang Yuan Ke-Yan Sun You Zou Jia-Yong Dong Jun-Song Ji Jun-Feng Dong Hong Fu Guo-Shan Ding Wen-Yuan Guo 2019World Journal of Clinical Cases2019,7,8:6
15Climate Change Impact and Its Contribution Share to Paddy Rice Production in Jiangxi, China显示文摘In the study,an improved approach was proposed to identify the contribution shares of three group factors that are climate,technology and input,social economic factors by which the grain production is shaped.In order to calibrate the method,Jiangxi Province,one of the main paddy rice producers in China was taken as an example.Based on 50 years(1961-2010)meteorological and statistic data,using GIS and statistical analysis tools,the three group factors that in certain extent impact China’s paddy rice production have been analyzed quantitatively.The individual and interactive contribution shares of each factor group have been identified via eta square(η2).In the paper,two group ordinary leasr square(OLS)models,paddy models and climate models,have been constructed for further analysis.Each model group consists of seven models,one full model and six partial models.The results of paddy models show that climate factors individually and interactively contribute 11.42-15.25%explanatory power to the variation of paddy rice production in the studied province.Technology and input factors contribute 16.17%individually and another 8.46%interactively together with climate factors,totally contributing about 25%.Social economic factors contribute about 7%of which 4.65%is individual contribution and 2.49%is interactive contribution together with climate factors.The three factor groups individually contribute about 23%and interactively contribute additional 41%to paddy rice production.In addition every two of the three factor groups also function interactively and contribute about 22%.Among the three factor groups,technology and input are the most important factors to paddy rice production.The results of climate models support the results of paddy models,and display that solar radiation(indicated by sunshine hour variable)is the dominate climate factor for paddy rice production.LI Wen-juan TANG Hua-jun QIN Zhi-hao YOU Fei WANG Xiu-fen CHEN Chang-li JI Jian-hua LIU Xiu-mei 2014Journal of Integrative Agriculture2014,13,7:6

17A real-time detection and positioning method for small and weak targets using a 1D morphology-based approach in 2D images显示文摘A small and weak target detection method is proposed in this work that outperforms all other methods in terms of real-time capability.It is the first time that two-dimensional(2D)images are processed using only one-dimensional1D structuring elements in a morphology-based approach,enabling the real-time hardware implementation of the whole image processing method.A parallel image readout and processing structure is introduced to achieve an ultra-low latency time on the order of nanoseconds,and a hyper-frame resolution in the time domain can be achieved by combining the row-by-row structure and the electrical rolling shutter technique.Experimental results suggest that the expected target can be successfully detected under various interferences with an accuracy of 0.1 pixels(1σ)under the worst sky night test condition and that a centroiding precision of better than 0.03 pixels(1σ)can be reached for static tests.The real-time detection method with high robustness and accuracy is attractive for application to all types of real-time small target detection systems,such as medical imaging,infrared surveillance,and target measurement and tracking,where an ultra-high processing speed is required.Min-Song Wei Fei Xing Zheng You 2018Light(Science & Applications)2018,7,1:6
18Space high-accuracy intelligence payload system with integrated attitude and position determination显示文摘recently,the requirements for space high resolution and high accuracy earth observation payloads are more urgent in many fields.However,traditional satellites mainly use the separation model of platform and payload.The precision of platform was unable to fulfill the requirements of high-precision imaging of payload.In addition,because traditional satellites mainly use the rigid connection between platform and payload,the precision of payload strongly depends on platform.They make satellite development and requirements increasingly difficult.To solve these disadvantages,in this paper,we introduce a Space High-accuracy integrated Intelligence Payload(SHIP) system with real-time attitude and position determination.SHIP can complete real time autonomous high accuracy attitude and position determination,high resolution remote sensing imaging,high-accuracy target position based on image,multi-mode motion imaging and target identification,tracking,self-recovery function of on orbit image,self-determination function of attitude and position,and so on.LI Jin XING Fei SUN Ting LIU Zengyi YOU Zheng 2015Instrumentation2015,2,1:5
19Plasma soluble C-type lectin-like receptor-2 is associated with the risk of coronary artery disease显示文摘Accumulating evidence suggests that C-type lectin-like receptor-2(CLEC-2)plays an important role in atherothrombosis.In this case-control study,we investigated the association between CLEC-2 and incidence of coronary artery disease(CAD).A total of 216 patients,including 14 cases of stable angina pectoris(SAP,non-ACS)and 202 cases of acute coronary syndrome(ACS),and 89 non-CAD control subjects were enrolled.Plasma levels of soluble CLEC-2(sCLEC-2)were measured using the enzyme-linked immunosorbent assay(ELISA).Compared with the control group(65.69(55.36–143.22)pg/mL),the plasma levels of sCLEC-2 were significantly increased in patients with CAD(133.67(88.76–220.09)pg/mL)and ACS(134.16(88.88–225.81)pg/mL).The multivariate adjusted odds ratios(95%confidence interval)of CAD reached 2.01(1.52–2.66)(Ptrend<0.001)for each 1-quartile increase in sCLEC-2.Restricted cubic splines showed a positive dose-response association between sCLEC2 and CAD incidence(Plinearity<0.001).The addition of sCLEC-2 to conventional risk factors improved the C statistic(0.821 vs.0.761,P=0.004)and reclassification ability(net reclassification improvement:57.45%,P<0.001;integrated discrimination improvement:8.27%,P<0.001)for CAD.In conclusion,high plasma sCLEC-2 is independently associated with CAD risk,and the prognostic value of sCLEC-2 may be evaluated in future prospective studies.Min Fei Li Xiang Xichen Chai Jingchun Jin Tao You Yiming Zhao Changgeng Ruan Yiwen Hao Li Zhu 2020Frontiers of Medicine2020,14,1:5
20Unraveling a genetic roadmap for improved taste in the domesticated apple显示文摘Although taste is an important aspect of fruit quality, an understanding of its genetic control remains elusive in apple and other fruit crops. In this study, we conducted genomic sequence analysis of 497 Malus accessions and revealed erosion of genetic diversity caused by apple breeding and possible independent domestication events of dessert and cider apples. Signatures of selection for fruit acidity and size, but not for fruit sugar content, were detected during the processes of both domestication and improvement. Furthermore, we found that single mutations in major genes affecting fruit taste, including Ma1, MdTDT, and MdSOT2, dramatically decrease malate, citrate, and sorbitol accumulation, respectively, and correspond to important domestication events. Interestingly, Ma1 was identified to have pleiotropic effects on both organic acid content and sugar:acid ratio, suggesting that it plays a vital role in determining fruit taste. Fruit taste is unlikely to have been negatively affected by linkage drag associated with selection for larger fruit that resulted from the pyramiding of multiple genes with minor effects on fruit size. Collectively, our study provides new insights into the genetic basis of fruit quality and its evolutionary roadmap during apple domestication, pinpointing several candidate genes for genetic manipulation of fruit taste in apple.Liao Liao Weihan Zhang Bo Zhang Ting Fang Xiao-Fei Wang Yarning Cai Collins Ogutu Lei Gao Gang Chen Xiaoqing Nie Jinsheng Xu Quanyan Zhang Yiran Ren Jianqiang Yu Chukun Wang Cecilia H.Deng Baiquan Ma Beibei Zheng Chun-Xiang You Da-Gang Hu Richard Espley Kui Lin-Wang Jia-Long Yao Andrew C.Allan Awais Khan Schuyler S.Korban Zhangjun Fei Ray Ming Yu-Jin Hao Li Li Yuepeng Han 2021Molecular Plant2021,14,9:5
