| 1 | Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants. | Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He | 2021 | National Science Review2021，8，2： | 47 |
| 2 | Chromopeptide A, a highly cytotoxic depsipeptide from the marine sediment-derived bacterium Chromobacterium sp. HS-13-94显示文摘A bicyclic depsipeptide, chromopeptide A(1), was isolated from a deep-sea-derived bacterium Chromobacterium sp. HS-13-94. Its structure was determined by extensive spectroscopic analysis and by comparison with a related known compound. The absolute configuration of chromopeptide A was established by X-ray diffraction analysis employing graphite monochromated Mo K_α radiation(λ ? 0.71073 ?) with small Flack parameter 0.03. Chromopeptide A suppressed the proliferation of HL-60, K-562, and Ramos cells with average IC_(50) values of 7.7, 7.0, and 16.5 nmol/L, respectively. | Zhenfang Zhou Xin Wang Hui Zhang Jingya Sun Linghui Zheng Hongchun Liu Jidong Wang Aijun Shen Meiyu Geng Yuewei Guo | 2015 | Acta Pharmaceutica Sinica B2015，5，1： | 6 |
| 3 | Dynamics and de-spin control of massive target by single tethered space tug显示文摘This paper investigates the dynamics and de-spin control of a massive target by a single tethered space tug in the post-capture phase. The dynamic model of the tethered system is derived and simplified to a dimensionless form. Further, a decoupled PD controller is proposed, and the local stability of the controller is analyzed by linearization technique. Parametric studies of the dynamics and de-spin control of a massive target are conducted to characterize the dynamic process of de-spin with the proposed control law. It is shown that the massive target can be de-span by a single and small space tug with limited thrust within finite time. The thrust tangent with the tether de-spins the target while the thrust normal to the tether prevents the tether from winding up the target. The tether length has a positive contribution to the de-spin of a target. The longer tether leads to a faster de-spin process. | Junjie KANG Zheng H.ZHU Wei WANG Changqing WANG Aijun LI | 2019 | Chinese Journal of Aeronautics2019，32，3： | 5 |

| 5 | Effects of temperature on flowering phenological traits of Populus euphratica Oliv. and Populus pruinosa Schrenk populations, Xinjiang, China显示文摘The aims of this study were to explore the interspecific differences of Populus euphratica Oliv.and Populus pruinosa Schrenk populations and the intraspecific differences of males and females within the same species in flowering phenological traits,and the effects of temperatures on flowering phenological traits in different growth years(2001–2003 and 2013–2015).The results showed that P.euphratica population flowered earlier than P.pruinosa population.Moreover,flowering phenological period of population,number of days of flowering phenological period per population,number of days of flowering phenological period per plant and average number of days of flowering period per plant of P.euphratica population were less than those of P.pruinosa population.The differences between male and female within the same species indicated that the flowering periods of males P.euphratica and P.pruinosa populations were earlier than those of female plants.For both species,flowering phenological traits were significantly and negatively correlated with the average temperatures in previous ten days,previous one month and previous three months of flowering.Both species are sensitive to temperature changes and adjust to the changes by advancing the start of flowering and prolonging the duration of flowering. | LI Zhijun ZHANG Xiao ZHENG Yaqiong QIU Aijun ZHANG Ling | 2019 | Journal of Arid Land2019，11，5： | 2 |
| 6 | Recent Progress in Atmospheric Chemistry Research in China: Establishing a Theoretical Framework for the “Air Pollution Complex”显示文摘Atmospheric chemistry research has been growing rapidly in China in the last 25 years since the concept of the“air pollution complex”was first proposed by Professor Xiaoyan TANG in 1997.For papers published in 2021 on air pollution(only papers included in the Web of Science Core Collection database were considered),more than 24000 papers were authored or co-authored by scientists working in China.In this paper,we review a limited number of representative and significant studies on atmospheric chemistry in China in the last few years,including studies on(1)sources and emission inventories,(2)atmospheric chemical processes,(3)interactions of air pollution with meteorology,weather and climate,(4)interactions between the biosphere and atmosphere,and(5)data assimilation.The intention was not to provide a complete review of all progress made in the last few years,but rather to serve as a starting point for learning more about atmospheric chemistry research in China.The advances reviewed in this paper have enabled a theoretical framework for the air pollution complex to be established,provided robust scientific support to highly successful air pollution control policies in China,and created great opportunities in education,training,and career development for many graduate students and young scientists.This paper further highlights that developing and low-income countries that are heavily affected by air pollution can benefit from these research advances,whilst at the same time acknowledging that many challenges and opportunities still remain in atmospheric chemistry research in China,to hopefully be addressed over the next few decades. | Tong ZHU Mingjin TANG Meng GAO Xinhui BI Junji CAO Huizheng CHE Jianmin CHEN Aijun DING Pingqing FU Jian GAO Yang GAO Maofa GE Xinlei GE Zhiwei HAN Hong HE Ru-Jin HUANG Xin HUANG Hong LIAO Cheng LIU Huan LIU Jianguo LIU Shaw Chen LIU Keding LU Qingxin MA Wei NIE Min SHAO Yu SONG Yele SUN Xiao TANG Tao WANG Tijian WANG Weigang WANG Xuemei WANG Zifa WANG Yan YIN Qiang ZHANG Weijun ZHANG Yanlin ZHANG Yunhong ZHANG Yu ZHAO Mei ZHENG Bin ZHU Jiang ZHU | 2023 | Advances in Atmospheric Sciences2023，40，8： | 2 |
| 7 | Coalfield structure and structural controls on coal in China显示文摘The occurrence of coal-bearing strata in a variety of coal-bearing basins of China is characterized by late tectonic deformation and remarkable spatial and geochronologic differences.The main controlling factors,which determine the tectonic framework of coalfields,include the geodynamic environment,tectonic evolution,deep structures,tectonic stress,and lithologic combination of the coal measures.The Chinese continent has experienced multi-stage tectonic movements since the Late Paleozoic.The spatial and temporal heterogeneity of its continental tectonic evolution,the complexity of its basement properties,and its stratigraphic configurations control the tectonic framework of its coalfields’present complex and orderly patterns.The concept of coal occurrence structural units is proposed in this paper and is defined as the structural zoning of coal occurrence.China’s coalfields are divided into five coal occurrence structural areas,and the structural characteristics of the coalfields in five main coal occurrence areas throughout the country are summarized.Based on the analysis of the relationship between the structure characteristics and occurrence of coal in these coalfields,the coal-controlling structures are divided into six groups:extensional structural styles,compressional structural styles,shearing and rotational structural styles,inverted structural styles,sliding structural styles,and syn-depositional structural styles.In addition,the distribution of coal-controlling structural styles is briefly summarized in this paper. | Daiyong Cao Anmin Wang Shuzheng Ning Huantong Li Aijun Guo Limin Chen Kang Liu Jieqing Tan Zhihong Zheng | 2020 | International Journal of Coal Science & Technology2020，7，2： | 2 |
| 8 | Direct reduction swelling behavior of pellets in hydrogen-based shaft furnaces under typical atmospheres显示文摘Hydrogen-based shaft furnace process is gaining more and more attention due to its low carbon emission, and the reduction behavior of iron bearing burdens significantly affects its operation. In this work, the effects of reduction degree, temperature, and atmosphere on the swelling behavior of pellet has been studied thoroughly under typical hydrogen metallurgy conditions. The results show that the pellets swelled rapidly in the early reduction stage, then reached a maximum reduction swelling index (RSI) at approximately 40%reduction degree. The crystalline transformation of the iron oxides during the reduction process was the main reason of pellets swelling. The RSI increased significantly with increasing temperature in the range of 850-1050℃, the maximum RSI increased from 6.66%to 25.0%in the gas composition of 100%H_(2). With the temperature increased, the pellets suffered more thermal stress resulting in an increase of the volume. The maximum RSI decreased from 19.78%to 17.35%with the volume proportion of H_(2) in the atmosphere increased from 55%to 100%at the temperature of 950℃.The metallic iron tended to precipitate in a lamellar structure rather than whiskers. Consequently, the inside of the pellets became regular, so the RSI decreased. Overall, controlling a reasonable temperature and increasing the H_(2) proportion is an effective way to decrease the RSI of pellets. | Zichuan Zhao Jue Tang Mansheng Chu Xindong Wang Aijun Zheng Xiaoai Wang Yang Li | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，10： | 2 |

| 16 | Behavioral problems and related factors in children of different aged patients with schizophrenia: A cross-sectional study显示文摘BACKGROUND:With the age growing,changes of behavioral problems in children whose parents had schizophrenia,differences of related factors and ways for particular intervention should be further studied. OBJECTIVE:To survey the behavioral problems in children of different aged patients with chizophrenia and investigate the correlation between behavioral problems and related factors in different aged groups. DESIGN:Cross-sectional study. SETTING:Shandong Mental Health Center. PARTICIPANTS:A total of 364 patients with schizophrenia were selected from eleven psychiatric hospitals from June 1999 to June 2000. There were 179 males and 185 females,and their ages ranged from 28 to 45 years. All patients met modified diagnostic criteria of schizophrenia(the second edition),China Classification of Mental Diseases and Diagnostic Criteria. Meanwhile,children of the 364 patients were grouped based on their ages,including 6-11 years old group [n =217;114 males and 103 females;mean age of(9±2) years] and 12-16 years old group [n =147;99 males and 48 females;mean age of(14± 1) years]. The Chinese norms of Achenbach's Child Behavior Check List were regarded as the normal control group. METHODS:Children who received self-made mental health related factors inventory and Achenbach's Child Behavior Check List were involved in this study. All children and their parents provided the confirmed consent. Achenbach's Child Behavior Check List was used for parents to mainly evaluate children,and the results manifested various behavioral problems based on different sexes and different ages. Self-made mental health related factors inventory contained questionnaires for parents and children,respectively. In this study,home situation of parents as well as personality characteristics and educational styles of children were mainly evaluated. MAIN OUTCOME MEASURES:① Scores of Achenbach's Child Behavior Check List in different aged children;② Scores of self-made mental health related factors inventory based on different home situations and educational styles. RESULTS:Children of 364 patients were involved in the final analysis. ① There were no significant differences in total score of Achenbach's Child Behavior Check List and sex in the two groups(P > 0.05). There were significant differences in schizoid,body recount,aggression,depression,hyperactivity,violating discipline,compulsion and total abnormal rate of boys between the 6-11 years old group and the normal control group(P < 0.05-0.01). In addition,there were also significant differences in poor communication,depression,hyperactivity,violating discipline,compulsion and total abnormal rate of girls between the 6-11 years old group and the normal control group(P < 0.05-0.01). ② As compared with normal control group,scores of home environment in the two aged groups demonstrated that educational level was low;interpersonal relationship was poor;relation to children was not closed;relationship between husband and wife was not harmonious;positive rate of family history was high;economic status was poor;family atmosphere was poor. Therefore,there was significant difference(P < 0.01). Educational level in parental generation and single parent family in the 6-11 years old group were higher than that in the 12-16 years old group,with significant difference(P < 0.05). As compared with the normal control group,results of education demonstrated that children in the two aged groups had poor communication with other children;they had poor behaviors in schools;most of them were boarded and had poor relationship with their parents;teaching styles for children were different. CONCLUSION:All children of different aged patients with schizophrenia had poor home environment and education;and they were often affected by other factors. Behavioral problems were changed with the age growing;in addition,these changes were related to home environment,education and society. Therefore,comprehensive intervention may be an ideal method. | Huimin Qiu Guifang Zhao Yangu Wang Mingyou Chen Jintong Liu Jisheng Tang Aijun Cui Yuying Zheng Chengyou Zhu Ping Li Shansong Wang Chengyong Sun Xueyun Qiao Wei Zhang Shengang Song Qingrong Li | 2007 | Neural Regeneration Research2007，2，11： | 0 |
| 17 | Rapid Screening of 26 Organophosphorus Pesticides in Fresh Milk by Ultra Liquid Chromatography Coupled With Quadrupole-Time of Flight Mass Spectrometry显示文摘[Objectives]A rapid screening and analysis method for 26 organophosphorus agrochemicals in fresh milk was established using ultra performance liquid chromatography coupled with quadrupole-time of flight mass spectrometry.[Methods]Raw milk was extracted with acetonitrile solution containing 0.2%formic acid by volume,and purified with a Dikma ProElut QuECHERS solid phase extraction cartridge.Target compounds were separated on a Waters ACQUITY UPLC HSS T3 chromatographic column(2.1 mm×50 mm,1.8μm)with methanol-water solution as a mobile phase for gradient elution,and through scanning with an electrospray ion source in positive ion mode,26 kinds of organophosphorus agrochemicals could be accurately qualitatively determined within 10 min.[Results]When using formic acid acetonitrile with a volume fraction of 0.2%,there were more types of detected compounds and a greater recovery;and using B cartridge could effectively eliminate the interference of non-polar substances such as phospholipids,achieve higher number of detected compounds than those of A and C,and well separate the 26 kinds of agrochemical residues.[Conclusions]This study provides a reference method for the rapid screening of agrochemical residues in dairy cows in the future. | Yi LI Luman HUO Lei WANG Lixue DONG Aijun LI Yi ZHANG Baiqin ZHENG | 2021 | Agricultural Biotechnology2021，10，5： | 0 |
| 18 | Cidan Capsule in Combination with Adjuvant Transarterial Chemoembolization Reduces Recurrence Rate after Curative Resection of Hepatocellular Carcinoma:A Multicenter,Randomized Controlled Trial显示文摘Objective:To evaluate the efficacy and safety of Cidan Capsule combined with adjuvant transarterial chemoembolization(TACE) in patients with a high risk of early recurrence after curative resection of hepatocellular carcinoma(HCC).Methods:A multicenter,randomized controlled trial was conducted in patients with high-risk recurrence factors after curative resection of HCC from 9 medical centers between July 2014 and July 2018.Totally249 patients were randomly assigned to TACE with or without Cidan Capsule administration groups by stratified block in a 1:1 ratio.Postoperative adjuvant TACE was given 4-5 weeks after hepatic resection in both groups.Additionally,125 patients in the TACE plus Cidan group were administrated Cidan Capsule(0.27 g/capsule,5 capsules every time,4 times a day) for 6 months with a 24-month follow-up.Primary endpoints included diseasefree survival(DFS) and tumor recurrence rate(TRR).Secondary endpoint was overall survival(OS).Any drugrelated adverse events(AEs) were observed and recorded.Results:As the data cutoff on July 9th,2018,the median DFS was not reached in the TACE plus Cidan group and 234.0 days in the TACE group(hazard ratio,0.420,95%confidence interval,0.290-0.608;P<0.01).The 1-and 2-year TRR in the TACE plus Cidan and TACE groups were 31.5%,37.1%,and 60.8%,63.4%,respectively(P<0.01).Median OS was not reached in both groups.The1-and 2-year OS rates in TACE plus Cidan and TACE groups were 98.4%,98.4%,and 89.5%,87.9%,respectively(P<0.05).The most common grade 3-4 AEs included fatigue,abdominal pain,lumbar pain,and nausea.One serious AE was reported in 1 patient in the TACE plus Cidan group,the death was due to retroperitoneal mass hemorrhage and hemorrhagic shock,and was not related to study drug.Conclusions:Cidan Capsule in combination with TACE can reduce the incidence of early recurrence in HCC patients at high-risk of recurrence after radical hepatectomy and may be an appropriate option in postoperative anti-recurrence treatment.(Registration No.NCT02253511) | ZHENG Dong-hai YANG Jia-mei WU Jian-xiong CHENG Shu-qun ZHANG Shao-geng WU Dong LI Aijun FU Xiao-hui LI Xun QI Fu-chen DUAN Wei-hong CHEN Jun-hui YANG Zhi-ying LIANG Lu ZENG Jin-xiong ZHENG Wei-da WU Meng-chao | 2023 | Chinese Journal of Integrative Medicine2023，29，1： | 0 |
