| 1 | High level of ezrin expression in colorectal cancer tissues is closely related to tumor malignancy显示文摘AIM:To investigate the ezrin expression in normal colorectal mucosa and colorectal cancer tissues, and study the correlation between ezrin expression in colorectal cancer tissues and tumor invasion and metastasis.METHODS: Eighty paraffin-embedded cancer tissue samples were selected from primary colorectal adenocarcinoma. Twenty-eight patients had well-differentiated, 22 had moderately differentiated and 30 had poorly differentiated adenocarcinoma. Forty-five patients and 35 patients had lymph node metastasis. Forty-five patients were of Dukes A to B stage, and 35 were of C to D stage. Another 22 paraffi n-embedded tissue blocks of normal colorectal epithelium (>5 cm away from the edge of the tumor) were selected as the control group. All patients with colorectal cancer were treated surgically and diagnosed histologically, without preoperative chemotherapy or radiotherapy. The immunohistochemistry was used to detect the ezrin expression in paraffin-embedded normal colorectal mucosa tissues and colorectal cancer tissue samples.RESULTS: Ezrin expression in colorectal cancer was significantly higher than in normal colorectal mucosa (75.00% vs 9.09%, P<0.01), and there was a close relationship between ezrin expression and the degree of tumor differentiation, lymph node metastasis and Dukes stage (88.46% vs 50.00%, P<0.01; 94.28% vs 51.11%, P<0.01; 94.28% vs 51.11%, P<0.01).CONCLUSION: Ezrin expression is obviously higher in colorectal cancer tissues than in normal colorectal mucosa tissues, and the high level of ezrin expression is closely related to the colorectal cancer invasion and metastasis process. | Hong-Jian Wang Jin-Shui Zhu Qiang Zhang Qun Sun Hua Guo | 2009 | World Journal of Gastroenterology2009，15，16： | 31 |
| 2 | The extremum principle of mass entransy dissipation and its application to decontamination ventilation designs in space station cabins显示文摘In terms of the analogy between mass and heat transfer phenomena, a new physical quantity, i.e. mass entransy, is introduced to represent the ability of an object for transferring mass to outside. Meanwhile, the mass entransy dissipation occurs during mass transfer processes as an alternative to measure the mass transfer irreversibility. Then the concepts of mass entransy and its dissipation are used to develop the extremum principle of mass entransy dissipation and the corresponding method for convective mass transfer optimization, based on which an Euler's equation has been deduced as the optimization equation for the fluid flow to obtain the best convective mass transfer performance with some specific constraints. As an example, the ventilation process for removing gaseous pollutants in a space station cabin with a uniform air supply system has been optimized to reduce the energy consumption of the ventilation system and decrease the contaminant concentration in the cabin. By solving the op- timization equation, an optimal air velocity distribution with the best decontamination performance for a given viscous dissipation is firstly obtained. With the guide of this optimal velocity field, a suitable concentrated air supply system with appropriate air inlet position and width has been designed to replace the uniform air supply system, which leads to the averaged and the maximum contaminant concentrations in the cabin been decreased by 75% and 60%, respectively, and the contaminant concentration near the contaminant source surface been decreased by 50%, while the viscous dissipation been reduced by 30% simultaneously. | CHEN Qun REN JianXun GUO ZengYuan | 2009 | Chinese Science Bulletin2009，54，16： | 26 |
| 3 | Thermodynamics and kinetics of phase transformation in rare earth–magnesium alloys:A critical review显示文摘Magnesium and its alloys are significant superior metallic materials for structural components in automobile and aerospace industries due to their excellent physicomechanical properties.The Mg–rare earth(RE)systems have attracted great interests because RE additions can improve both the deformability and the strength of Mg alloys through solid solution strengthening and precipitation hardening mechanisms.This paper focuses on the interface stability,together with thermodynamics and kinetics of nucleation and growth of the key phases and matrix phases in Mg–RE alloys.In this paper,the theory and recent advances on Mg–RE alloys,especially for the interface stability,thermodynamics and kinetics of nucleation and growth of the key phases and matrix phases,together with their relationships with micro-structures,and macroscopic properties,are reviewed.By combining the thermodynamics/kinetics integrated simulations with various advanced experimental techniques,“reverse”design of Mg–RE alloys starting from the target service performance is put forward as a kind of scientific paradigm with rational design. | Qun Luo Yanlin Guo Bin Liu Yujun Feng Jieyu Zhang Qian Li Kuochih Chou | 2020 | Journal of Materials Science & Technology2020，44，9： | 26 |
| 4 | Fluid flow field synergy principle and its application to drag reduction显示文摘The concept of field synergy for fluid flow is introduced, which refers to the synergy of the velocity field and the velocity gradient field in an entire flow domain. Analyses show that the flow drag depends not only on the velocity and the velocity gradient fields but also on their synergy. The principle of minimum dissipation of mechanical energy is developed, which may be stated as follows: the worse the synergy between the velocity and velocity gradient fields is, the smaller the resistance becomes. Furthermore, based on the principle of minimum dissipation of mechanical energy together with conservation equa-tions, a field synergy equation with a set of specified constraints has been established for optimizing flow processes. The optimal flow field can be obtained by solving the field synergy equation, which leads to the minimum resistance to fluid flow in the fixed flow domain. Finally, as an example, the field synergy analysis for duct flow with two parallel branches is presented. The optimized velocity dis-tributor nearby the fork, which was designed based on the principle of minimum dissipation of me-chanical energy, may reduce the drag of duct flow with two parallel branches. | CHEN Qun REN JianXunt GUO ZengYuan | 2008 | Chinese Science Bulletin2008，53，11： | 21 |
| 5 | Moisture transfer resistance method for liquid desiccant dehumidification analysis and optimization显示文摘The concepts of entransy, entransy dissipation and transfer resistance are introduced into liquid desiccant dehumidification analysis to reveal the irreversibility and moisture transfer resistance between moist air and liquid desiccant.By analyzing a typical water (vapor) transfer process coupled with heat transfer, we define the concepts of mass entransy of water and its dissipation, derive the expression of moisture transfer resistance (MTR) that reflects the irreversibility of water transfer during dehumidification processes, and also point out the relationship between MTR and dehumidification performance. With these concepts, both adiabatic and internal cooling liquid desiccant dehumidification systems with various operation conditions are analyzed and optimized. It is found that for the adiabatic dehumidification system, increasing the mass transfer coefficient leads to the reduction of MTR, and consequently, the improvement of dehumidification performance. Meanwhile, for the dehumidification system with internal cooling, in order to reduce the MTR and improve the dehumidification performance, pre-cooling should be centralized ahead of the liquid desiccant inlet when the flow rates ratio of air to desiccant is small, whereas, uniform cooling should be applied when the flow rates ratio of air to desiccant is large. | CHEN Lin CHEN Qun LI Zhen GUO ZengYuan | 2010 | Chinese Science Bulletin2010，55，14： | 20 |
| 6 | A comparison of optimization theories for energy conservation in heat exchanger groups显示文摘In general,thermal processes can be classified into two categories: heat-work conversion processes and heat transfer processes. Correspondingly,the optimization of thermal processes has to have two different criteria:the well known entropy generation minimization method and the recently proposed entransy dissipation maximization method. This study analyzes the thermal issues in a heat exchanger group,and optimizes the unit arrangements under different constraints based on a suitable optimization crite-rion. The result indicates that the principle of minimum entropy generation rate is valid for optimizing heat exchangers in a ther-modynamic cycle with given boundary temperatures. In contrast,the entransy dissipation maximization is more suitable in heat exchanger optimizations involving only heat transfer processes. Furthermore,the entropy generation rate induced by dumping used streams into ambient surroundings has to be taken into account,except for that originating from the hot and cold-ends of heat exchangers,when using the entropy generation minimization to optimize heat exchangers undergoing a thermodynamic cycle. | CHEN Qun WU Jing WANG MoRan PAN Ning GUO ZengYuan | 2011 | Chinese Science Bulletin2011，56，4： | 20 |
| 7 | Effect of wide-narrow row arrangement in mechanical pot-seedling transplanting and plant density on yield formation and grain quality of japonica rice显示文摘Mechanical pot-seedling transplanting is an innovatively developed transplanting method that has the potential to replace mechanical carpet-seedling transplanting. However, the initial pot-seedling transplanting machine lacked optimized density spacing and limited yield potential for japonica rice. Therefore, ascertaining the optimized density by wide-narrow rows and the appropriate transplanting method for yield formation and grain quality of japonica rice is of great importance for high-quality rice production. Field experiments were conducted using two japonica rice cultivars Nanjing 9108 and Nanjing 5055 under three transplanting methods in 2016 and 2017: mechanical pot-seedling transplanting with wide-narrow row(K, average row spacing of 30 cm);equidistant row(D, 33 cm×12 cm);and mechanical carpet-seedling transplanting(T, 30 cm×12.4 cm). In addition, five different density treatments were set in K(K1–K5, from 18.62×10~4 to 28.49×10~4 hills ha^(–1)). The results showed that the highest yield was produced by a planting density of 26.88×104 hills ha^(–1) in mechanical pot-seedling transplanting with wide-narrow row with a greater number of total spikelets that resulted from significantly more panicles per area and slightly more grain number per panicle, as compared with equidistant row, and yield among density in wide-narrow row showed a parabolic trend. Compared with mechanical carpet-seedling transplanting, the treatment of the highest yield increased yield significantly, which was mainly attributed to the larger sink size with improved filled-grain percentage and grain weight, higher harvest index, and increased total dry matter accumulation, especially the larger amount accumulated from heading stage to maturity stage. With the density in wide-narrow row decreasing, processing quality, appearance quality, and nutrition quality were all improved, whereas amylose content and the taste value were decreased. Compared with mechanical carpet-seedling transplanting, mechanical pot-seedling transplanting improved processing quality and nutrition quality, but decreased amylose content and deteriorated appearance quality. These results suggested that mechanical pot-seedling transplanting with wide-narrow row coupling produced a suitable planting density of 26.88×10~4 hills ha^(–1) and may be an alternative approach to improving grain yield and quality for japonica rice. | HU Qun JIANG Wei-qin QIU Shi XING Zhi-peng HU Ya-jie GUO Bao-wei LIU Guo-dong GAO Hui ZHANG Hong-cheng WEI Hai-yan | 2020 | Journal of Integrative Agriculture2020，19，5： | 19 |
| 8 | The property diagram in heat transfer and its applications显示文摘Inspired by the property diagrams in thermodynamics,which distinctly reflect the performance and characteristics of thermodynamic cycles,we establish a state equation for heat motion and introduce a two-dimension property diagram,T-q diagram,in heat transfer to analyze and optimize the performance of heat exchangers,where heat flow is a state parameter for heat motion.According to the property diagram,it is convenient to obtain the influences of heat exchanger area,heat capacity rate and flow arrangement on the heat transfer performance during the analysis of heat exchangers and their networks.For instance,when analyzing the heat exchanger network in a district heating system,it is obvious to find that:if both the heat demand and the indoor air temperature in each branch of the network are the same,the total area of heat exchangers,the flow rate of water and the return water temperature in each branch are all the same;if the indoor air temperatures in different branches are different,the temperatures of the waters after flowing through different branches are different,which means that the mixing process of return waters with the same temperature is not an essential requirement to realize the best performance of district heating systems. | CHEN Qun XU YunChao GUO ZengYuan | 2012 | Chinese Science Bulletin2012，57，35： | 17 |

| 10 | 2D MOF Nanoflake-Assembled Spherical Microstructures for Enhanced Supercapacitor and Electrocatalysis Performances显示文摘Metal–organic frameworks(MOFs) are of great interest as potential electrochemically active materials.However, few studies have been conducted into understanding whether control of the shape and components of MOFs can optimize their electrochemical performances due to the rational realization of their shapes. Component control of MOFs remains a significant challenge. Herein, we demonstrate a solvothermal method to realize nanostructure engineering of 2D nanoflake MOFs. The hollow structures withNi/Co-and Ni-MOF(denoted as Ni/Co-MOF nanoflakes and Ni-MOF nanoflakes) were assembled for their electrochemical performance optimizations in supercapacitors and in the oxygen reduction reaction(ORR). As a result, the Ni/CoMOF nanoflakes exhibited remarkably enhanced performance with a specific capacitance of 530.4 F g^(-1)at 0.5 A g^(-1)in1 M LiO H aqueous solution, much higher than that of NiMOF(306.8 F g^(-1)) and ZIF-67(168.3 F g^(-1)), a good rate capability, and a robust cycling performance with no capacity fading after 2000 cycles. Ni/Co-MOF nanoflakes also showed improved electrocatalytic performance for the ORR compared to Ni-MOF and ZIF-67. The present work highlights the significant role of tuning 2D nanoflake ensembles of Ni/Co-MOF in accelerating electron and charge transportation for optimizing energy storage and conversion devices. | Huicong Xia Jianan Zhang Zhao Yang Shiyu Guo Shihui Guo Qun Xu | 2017 | Nano-Micro Letters2017，9，4： | 14 |
| 11 | Low-complexity 2D coherently distributed sources decoupled DOAs estimation method显示文摘The existing directions-of-arrival(DOAs) estimation methods for two-dimensional(2D) coherently distributed sources need one-or two-dimensional search,and the computational complexities of them are high. In addition,most of them are designed for special angular signal distribution functions. As a result,their performances will degenerate when deal with different sources with different angular signal distribution functions or unknown angular signal distribution functions. In this paper,a low-complexity decoupled DOAs estimation method without searching using two parallel uniform linear arrays(ULAs) is proposed for coherently distributed sources,as well as a novel parameter matching method. It can resolve the problems mentioned above efficiently. Simulation results validate the effectiveness of our approach. | GUO XianSheng WAN Qun YANG WanLin LEI XueMei | 2009 | Science in China(Series F)2009，52，5： | 12 |

| 14 | Effect of rGO Coating on Interconnected Co_3O_4 Nanosheets and Improved Supercapacitive Behavior of Co_3O_4/rGO/NF Architecture显示文摘In this study, the effect of reduced graphene oxide(rGO) on interconnected Co_3O_4 nanosheets and the improved supercapacitive behaviors is reported. By optimizing the experimental parameters, we achieved a specific capacitance of ~1016.4 F g^(-1) for the Co_3O_4/rGO/NF(nickel foam) system at a current density of 1 A g^(-1). However, the Co_3O_4/NF structure without rGO only delivers a specific capacitance of ~520.0 F g^(-1)at the same current density. The stability test demonstrates that Co_3O_4/rGO/NF retains ~95.5% of the initial capacitance value even after 3000 charge–discharge cycles at a high current density of 7 A g^(-1). Further investigation reveals that capacitance improvement for the Co_3O_4/rGO/NF structure is mainly because of a higher specific surface area(~87.8 m^2g^(-1))and a more optimal mesoporous size(4–15 nm) compared to the corresponding values of 67.1 m^2g^(-1) and 6–25 nm,respectively, for the Co_3O_4/NF structure. rGO and the thinner Co_3O_4 nanosheets benefit from the strain relaxation during the charge and discharge processes, improving the cycling stability of Co_3O_4/rGO/NF. | Tinghui Yao Xin Guo Shengchun Qin Fangyuan Xia Qun Li Yali Li Qiang Chen Junshuai Li Deyan He | 2017 | Nano-Micro Letters2017，9，4： | 8 |

| 16 | Impact of land use conversion on soil organic carbon stocks in an agro-pastoral ecotone of Inner Mongolia显示文摘Soil organic carbon(SOC) stocks in terrestrial ecosystems vary considerably with land use types. Grassland, forest, and cropland coexist in the agro-pastoral ecotone of Inner Mongolia, China. Using SOC data compiled from literature and field investigations, this study compared SOC stocks and their vertical distributions among three types of ecosystems. The results indicate that grassland had the largest SOC stock, which was 1.5-and 1.8-folds more than stocks in forest and cropland, respectively. Relative to the stock in 0–100 cm depth, grassland held more than 40% of its SOC stock in the upper 20 cm soil layer; forest and cropland both held over 30% of their respective SOC stocks in the upper 20 cm soil layer. SOC stocks in grazed grasslands were remarkably promoted after ≥20 years of grazing exclusion. Conservational cultivation substantially increased the SOC stocks in cropland, especially in the 0–40 cm depth. Stand ages, tree species, and forest types did not have obvious impacts on forest SOC stocks in the study area likely due to the younger stand ages. Our study implies that soil carbon loss should be taken into account during the implementation of ecological projects, such as reclamation and afforestation, in the arid and semi-arid regions of China. | ZHAO Wei HU Zhongmin LI Shenggong GUO Qun YANG Hao ZHANG Tonghui | 2017 | Journal of Geographical Sciences2017，27，8： | 8 |
| 17 | Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes. | MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 无 | 2020 | Biomedical and Environmental Sciences2020，33，12： | 8 |
| 18 | Children with Steroid-resistant Nephrotic Syndrome:Long-term Outcomes of Sequential Steroid Therapy显示文摘Objective This study aimed to investigate the long-term outcomes in children with steroid-resistant nephrotic syndrome(SRNS), who received methylprednisolone pulse therapy(MPT)-based sequential steroid therapy. In particular, we aimed to observe whether these patients had a high risk of adverse events. Methods We conducted a retrospective study over a 5-year period. The long-term outcomes for children with SRNS receiving sequential therapy were observed. Results Sixty-three children were diagnosed with SRNS and underwent MPT-based sequential steroid therapy. Thirty-five(55.6%) achieved complete or partial remission, 19(30.2%) of whom were in remission even after treatment cessation at last review. The mean time to initial remission after MPT was 24.3±13.1 days. Forty-nine children(77.8%) experienced relapses, of whom 31(49.2%) demonstrated a frequent relapsing course. Adverse effects relevant to MPT were generally mild and infrequent. Five patients(7.9%) complained of vomiting or nausea during MPT infusion; 25(39.7%) experienced excessive weight gain and developed an obvious Cushingoid appearance; and 26(41.3%) had poor growth associated with long-term steroid use. Twenty-eight patients(44.4%) failed to respond to MPT, of whom 21(33.3%) achieved complete or partial remission with immunosuppressive agents. Conclusion MPT-based sequential steroid therapy appears to be a safe and effective method for inducing rapid remission in childhood SRNS. Further clinical studies are needed to comprehensively evaluate this therapy. | ZHANG Hui WANG Zheng DONG Li Qun GUO Yan Nan | 2016 | Biomedical and Environmental Sciences2016，29，9： | 7 |
| 19 | Pristimerin protects against inflammation and metabolic disorder in mice through inhibition of NLRP3 inflammasome activation显示文摘Excessive activation of NLRP3 inflammasome is associated with the pathogenesis of inflammatory diseases.Pristimerin(Pri)is a quinonoid triterpene derived from traditional Chinese medical herb Celastraceae and Hippocrateaceae.Pri has shown antifungal,antibacterial,antioxidant,and anticancer activities.In this study we investigated whether NLRP3 inflammasome was associated with the anti-inflammatory activity of Pri.We showed that Pri(0.1−0.4μM)dose-dependently blocked caspase-1 activation and IL-1βmaturation in LPS-primed mouse bone-marrow-derived macrophages(BMDMs).Pri specifically inhibited NLRP3 inflammasome activation,had no visible effects on NLRC4 and AIM2 inflammasome activation.Furthermore,we demonstrated that Pri blocked the assembly of the NLRP3 inflammasome via disturbing the interaction between NEK7 and NLRP3;theα,β-unsaturated carbonyl moiety of Pri was essential for NLRP3 inflammasome inactivation.In LPS-induced systemic inflammation mouse model and MSU-induced mouse peritonitis model,preinjection of Pri(500μg/kg,ip)produced remarkable therapeutic effects via inhibition of NLRP3 inflammasome in vivo.In HFD-induced diabetic mouse model,administration of Pri(100μg·kg^(−1)·d^(−1),ip,for 6 weeks)reversed HFD-induced metabolic disorders via suppression of NLRP3 inflammasome activation.Taken together,our results demonstrate that Pri acts as a NLRP3 inhibitor,suggesting that Pri might be useful for the treatment of NLRP3-associated diseases. | Qun Zhao Yun Bi Jian Guo Ying-xiang Liu Jing Zhong Long-rui Pan Yan Tan Xian-jun Yu | 2021 | Acta Pharmacologica Sinica2021，42，6： | 6 |
| 20 | Relationship between Ambient Fine Particles and Ventricular Repolarization Changes and Heart Rate Variability of Elderly People with Heart Disease in Beijing, China显示文摘Objective To explore the effects of particulate matters less than 2.5 μm in aerodynamic diameter (PM 2.5) on heart repolarization/depolarization and heart rate variability (HRV). Methods We conducted a panel study for elderly subjects with heart disease in Beijing from 2007 to 2008. PM 2.5 was measured at a fixed station for 20 h continuously each day while electrocardiogram (ECG) indexes of 42 subjects were also recorded repeatedly. Meteorological data was obtained from the China Meteorological Data Sharing Service System. A mixed linear regression model was used to estimate the associations between PM 2.5 and the ECG indexes. The model was adjusted for age, body mass index, sex, day of the week andmeteorology. Results Significant adverse effects of PM 2.5 on ECG indexes reflecting HRV were observed statistically and the strongest effect of PM 2.5 on HRV was on lag 1 day in our study. However, there were no associations between PM 2.5 and ECG indexes reflecting heart repolarization/depolarization. Additionally, the effects of PM 2.5 on subjects with hypertension were larger than on the subjects without hypertension. Conclusion This study showed ambient PM 2.5 could affect cardiac autonomic function of the elderly people with heart disease, and subjects with hypertension appeared to be more susceptive to the autonomic dysfunction induced by PM 2.5. | XU Mei Mei JIA Yu Ping LI Guo Xing LIU Li Qun MO Yun Zheng JIN Xiao Bin PAN Xiao Chuan | 2013 | Biomedical and Environmental Sciences2013，26，8： | 6 |
