| 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 |

| 5 | High-speed flowing plasmas in the Earth’s plasma sheet显示文摘A research topic of great interest to the space physics community is the observation of plasmas flowing at hundreds of kilometers per second in the Earth’s plasma sheet. Although considerable effort has been made to understand the source of fast-flowing plasmas, many questions remain unanswered about the mechanisms that produce high-speed flows and the effects they have on magnetospheric disturbances, especially their contributions to magnetospheric convection and substorms. In this paper, we discuss briefly the history of high-speed flows and review the proposed mechanisms, signatures of high-speed flows in auroras and their interaction with the background plasma. We then summarize the relationships between high-speed flows and magnetic structures, discuss questions associated with substorms, and finally pose several important scientific questions that need to be addressed. | FU SuiYan SHI QuanQi WANG Chi PARKS George ZHENG Ling ZHENG Hao SUN WeiJie | 2011 | Chinese Science Bulletin2011,56,12: | 9 |

| 7 | Experimental and numerical studies of a lean-burn internally-staged combustor显示文摘A lean-burn internally-staged combustor for low emissions that can be used in civil aviation gas turbines is introduced in this paper. The main stage is designed and optimized in terms of fuel evaporation ratio, fuel/air pre-mixture uniformity, and particle residence time using commercial computational fluid dynamics(CFD) software. A single-module rectangular combustor is adopted in performance tests including lean ignition, lean blowout, combustion efficiency, emissions, and combustion oscillation using aviation kerosene. Furthermore, nitrogen oxides(NOx)emission is also predicted using CFD simulation to compare with test results. Under normal inlet temperature, this combustor can be ignited easily with normal and negative inlet pressures. The lean blowout fuel/air ratio(LBO FAR) at the idle condition is 0.0049. The fuel split proportions between the pilot and main stages are determined through balancing emissions, combustion efficiency, and combustion oscillation. Within the landing and take-off(LTO) cycle, this combustor enables 42%NOxreduction of the standard set by the 6th Committee on Aviation Environmental Protection(CAEP/6) with high combustion efficiency. The maximum board-band pressure oscillations of inlet air and fuel are below 1% of total pressure during steady-state operations at the LTO cycle specific conditions. | Fu Zhenbo Lin Yuzhen Li Lin Zhang Chi | 2014 | Chinese Journal of Aeronautics2014,27,3: | 9 |
| 8 | Olivine-norite rock detected by the lunar rover Yutu-2 likely crystallized from the SPA-impact melt pool显示文摘Chang’E-4 landed in the South Pole-Aitken(SPA)basin,providing a unique chance to probe the composition of the lunar interior.Its landing site is located on ejecta strips in Von Karm´an crater that´possibly originate from the neighboring Finsen crater.A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations.In situ spectra of the regolith have peak band positions at 1 and 2μm,similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper,which confirms that the regolith’s composition of the landing area is mostly similar to that of Finsen ejecta.The rock spectrum shows similar band peak positions,but stronger absorptions,suggesting relatively fresh exposure.The rock may consist of 38.1±5.4%low-Ca pyroxene,13.9±5.1%olivine and 48.0±3.1%plagioclase,referred to as olivine-norite.The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle,but representative of the lunar lower crust.Alternatively,the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials.This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool,indicated by the fine to medium-sized texture(<3 mm)of the rock and the SPA-impact melting model[Icarus 2012;220:730–43]. | Honglei Lin Zhiping He Wei Yang Yangting Lin Rui Xu Chi Zhang Meng-Hua Zhu Rui Chang Jinhai Zhang Chunlai Li Hongyu Lin Yang Liu Sheng Gou Yong Wei Sen Hu Changbin Xue Jianfeng Yang Jie Zhong Xiaohui Fu Weixing Wan Yongliao Zou | 2020 | National Science Review2020,7,5: | 9 |
| 9 | Effect of Combined Application of Organic Fertilizer and Chemical Fertilizer in Different Ratios on Growth,Yield and Quality of Fluecured Tobacco显示文摘The effect of different ratio of organic and inorganic fertilizers on the growth and the yield and quality of flue-cured tobacco was studied.Using randomized blocks design,the data of the test materials K326 were analyzed by using variance analysis,significance test and other methods.The release efficiency of organic fertilizer in the soil was slower,and the effect of organic fertilizer on the growth of tobacco plants was worse than that of chemical fertilizers,and under 25% organic fertilizer + 75% chemical fertilizer treatment,the quality of the fluecured tobacco was good.Under the treatment of 50% organic fertilizer + 50% chemical fertilizer,the production of flue-cured tobacco was high and the ratio of first-class tobacco was high.It is suggested that the organic fertilizer application ratio should be 25%-50% in the agricultural production. | Bing LIANG Kun HUANG Yali FU Hongguang LI Chi WANG Xiaotian ZHONG Qinghua LU Chengxiao HU | 2017 | Asian Agricultural Research2017,9,12: | 9 |
| 10 | Regulating Effects of Novel CpG Chitosan-nanoparticles on Immune Responses of Mice to Porcine Paratyphoid Vaccines显示文摘Objective To study the regulating effects of a novel CpG oligodeoxynuleotide and the synergistic effect of chitosan-nanoparticles (CNP) with CpG on immune responses of mice, which were used to develop a novel immunoadjuvant to boost immune response to conventional vaccines. Methods A novel CpG ODN containing 11 CpG motifs was synthesized and its bioactivities to stimulate the proliferation of lymphocytes of pig in vitro were detected. Then it was entrapped with CNP prepared in our laboratory by the method of ionic cross linkage, and immunized Kunming mice were co-inoculated with paratyphoid vaccine. The peripheral blood was collected weekly from the tail vein of inoculated mice to detect the contents of IgG, IgA, IgM, and specific antibody against salmonella as well as the levels of interleukin-2 (IL2), IL-4, and IL-6 by SABC-ELISA assay. The numbers of leucocytes, monocytes, granuloytes, and lymphocytes were calculated separately using the routine method. The experimental mice were orally challenged with virulent salmonella 35 days after inoculation. Results This CpG ODN could remarkably provoke the proliferation of lymphocytes of pig in vitro in contrast with the control (P<0.05). Compared with those of the control, immunoglobulins, including IgG, IgA, IgM, and specific antibodies to paratyphoid vaccine, increased significantly in sera from the CpG or CpG-CNP-vaccinated mice (P<0.05). IL-2, IL-4, and IL-6 increased remarkably in sera from immunized mice (P<0.05). The leucocytes, monocytes, granuloytes, and lymphocytes of the mice immunized with CpG or CpG-CNP were also increased in number (P<0.05). After the challenge, these immunity values were elevated in the mice vaccinated with CpG or CpG-CNP. The immunized mice all survived, while the control mice fell ill with evident lesions with diffuse hemorrhage in stomach, small intestine, and peritoneum. Conclusions CpG ODN entrapped with CNP is a promising effective immunoadjuvant for vaccination, which promotes humoral and cellular immune responses, enhances immunity and resistance against salmonella by co-administration with paratyphoid vaccine. | MAN-LIANG FU SAN-CHENG YING MEI WU HUI LI KAI-YUAN WU YI YANG HUAN ZHANG CHI CHENG ZE-ZHOU WANG XIU-YING WANG XUE-BING LV YI-ZHENG ZHANG RONG GAO | 2006 | Biomedical and Environmental Sciences2006,19,4: | 8 |

| 12 | Prognostic factors and therapeutic effects of different treatment modalities for colorectal cancer liver metastases显示文摘BACKGROUND Colorectal cancer(CRC)is one of the most common malignant tumors in China,and the liver is the most common metastatic site in patients with advanced CRC.Hepatectomy is the gold standard treatment for colorectal liver metastases.For patients who cannot undergo radical resection of liver metastases for various reasons,ablation therapy,interventional therapy,and systemic chemotherapy can be used to improve their quality of life and prolong their survival time.AIM To explore the prognostic factors and treatments of liver metastases of CRC.METHODS A retrospective analysis was conducted on 87 patients with liver metastases from CRC treated at the Liaoning Cancer Hospital and Institute between January 2005 and March 2011.According to different treatments,the patients were divided into the following four groups:Surgical resection group(36 patients);ablation group(23 patients);intervention group(15 patients);and drug group(13 patients).The clinicopathological data and postoperative survival of the four groups were analyzed.The Kaplan-Meier method was used for survival analysis,and the Cox proportional hazards regression model was used for multivariate analysis.RESULTS The median survival time of the 87 patients was 38.747±3.062 mo,and the 1-and 3-year survival rates were 87.5%and 53.1%,respectively.The Cox proportional hazards model showed that the following factors were independent factors affecting prognosis:The degree of tumor differentiation,the number of metastases,the size of metastases,and whether the metastases are close to great vessels.The results of treatment factor analysis showed that the effect of surgical treatment was better than that of drugs,intervention,or ablation alone,and the median survival time was 48.83±4.36 mo.The drug group had the worst prognosis,with a median survival time of only 13.5±0.7 mo(P<0.05).For patients with liver metastases of CRC near the great vessels,the median survival time(27.3 mo)of patients undergoing surgical resection was better than that of patients using other treatments(20.6 mo)(P<0.05).CONCLUSION Patients with a low degree of primary tumor differentiation,multiple liver metastases(number of tumors>4),and maximum diameter of liver metastases>5 cm have a poor prognosis.Among drug therapy,intervention,ablation,and surgical treatment options,surgical treatment is the first choice for liver metastases.When liver metastases are close to great vessels,surgical treatment is significantly better than drug therapy,intervention,and ablation alone. | Zuo-Hong Ma Yong-Peng Wang Wen-Heng Zheng Ji Ma Xue Bai Yong Zhang Yuan-He Wang Da Chi Xi-Bo Fu Xiang-Dong Hua | 2020 | World Journal of Gastrointestinal Oncology2020,12,10: | 7 |

| 18 | Activatingα7nAChR ameliorates abdominal aortic aneurysm through inhibiting pyroptosis mediated by NLRP3 inflammasome显示文摘Abdominal aortic aneurysm(AAA)is defined as a dilated aorta in diameter at least 1.5 times of a normal aorta.Our previous studies found that activatingα7 nicotinic acetylcholine receptor(α7nAChR)had a protective effect on vascular injury.This work was to investigate whether activatingα7nAChR could influence AAA formation and explore its mechanisms.AAA models were established by angiotensin II(Ang II)infusion in ApoE^(-/-)mice or in wild type andα7nAChR^(-/-)mice.In vitro mouse aortic smooth muscle(MOVAS)cells were treated with tumor necrosis factor-α(TNF-α).PNU-282987 was chosen to activateα7nAChR.We found that cell pyroptosis effector GSDMD and NLRP3 inflammasome were activated in abdominal aorta,and inflammatory cytokines in serum were elevated in AAA models of ApoE^(-/-)mice.Activatingα7nAChR reduced maximal aortic diameters,preserved elastin integrity and decreased inflammatory responses in ApoE^(-/-)mice with Ang II infusion.Whileα7nAChR^(-/-)mice led to aggravated aortic injury and increased inflammatory cytokines with Ang II infusion when compared with wild type.Moreover,activatingα7nAChR inhibited NLRP3/caspase-1/GSDMD pathway in AAA model of ApoE^(-/-)mice,whileα7nAChR deficiency promoted this pathway.In vitro,N-acetylcysteine(NAC)inhibited NLRP3 inflammasome activation and NLRP3 knockdown reduced GSDMD expression,in MOVAS cells treated with TNF-α.Furthermore,activatingα7nAChR inhibited oxidative stress,reduced NLRP3/GSDMD expression,and decreased cell pyroptosis in MOVAS cells with TNF-α.In conclusion,our study found that activatingα7nAChR retarded AAA through inhibiting pyroptosis mediated by NLRP3 inflammasome.These suggested thatα7nAChR would be a potential pharmacological target for AAA. | Hui Fu Qi-rui Shen Yi Zhao Min Ni Can-can Zhou Ji-kuai Chen Chen Chi Dong-jie Li Guang Liang Fu-ming Shen | 2022 | Acta Pharmacologica Sinica2022,43,10: | 3 |
| 19 | LKB1 orchestrates dendritic cell metabolic quiescence and anti-tumor immunity显示文摘Den dritic cells(DCs)play a pivotal role in priming adaptive immunity.However,the in volveme nt of DCs in con trolling excessive and deleterious T cell responses remains poorly defined.Moreover,the metabolic dependenee and regulation of DC function are unclear.Here we show that LKB1 signaling in DCs functions as a brake to restrain excessive tumor-promoting regulatory T cell(Treg)and Th17 cell responses,thereby promoting protective anti-tumor immunity and maintaining proper immune homeostasis.LKB1 deficiency results in dysregulated metabolism and mTOR activation of DCs.Loss of LKB1 also leads to aberrant DC maturation and production of cytokines and immunoregulatory molecules.Blocking mTOR signaling in LKB1-deficient DCs partially rectifies the abno rmal phe no types of DC activation and Treg expansio n,whereas unc on trolled Th17 resp on ses depend upon IL-6-STAT3 signaling.By coordi nating metabolic and immune quiesce nee of DCs,LKB1 acts as a crucial signali ng hub in DCs to enforce protective anti-tumor immunity and normal immune homeostasis. | Yanyan Wang Xingrong Du Jun Wei Lingyun Long Haiyan Tan Cliff Guy Yogesh Dhungana Chenxi Qian Geoffrey Neale Yang-Xin Fu Jiyang Yu Junmin Peng Hongbo Chi | 2019 | Cell Research2019,29,5: | 3 |
| 20 | Oxygen Atom Exchange Mechanism in Reaction of OH Radical with AsO显示文摘Oxygen atom exchange reaction mechanism in the reaction of OH radicals with AsO was investigated by means of the density functional theory (DFT) with 6 311++G( 3df,3pd ) and 6 311++G( d,p ) basis sets. The calculated results suggest that the reaction between OH and AsO should make the oxygen atoms exchange rapidly because the barrier to isomerization is significantly less than the HO-AsO bond dissociation energy. | CHI Yu-juan 1, YU Hai tao 1,2** , FU Hong gang 1,2 HUANG Xu ri 2, LI Ze sheng 2 and SUN Chia chung 21.
