| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)显示文摘In recent years,as living standards have continued to improve,the number of diabetes patients in China,along with the incidence of complications associated with the disease,has been increasing.Among these complications,diabetic foot disease is one of the main causes of disability and death in diabetic patients.Due to the differences in economy,culture,religion and level of medical care available across different regions,preventive and treatment methods and curative results for diabetic foot vary greatly.In multidisciplinary models built around diabetic foot,the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology.In 2019,under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society,the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)was established with the participation of scholars from the specialist areas of endocrinology,burn injury,vascular surgery,orthopedics,foot and ankle surgery and cardiology.Drawing lessons from diabetic foot guidelines from other countries,this guide analyses clinical practices for diabetic foot,queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China.This paper begins with assessments and diagnoses of diabetic foot,then describes treatments for diabetic foot in detail,and ends with protections for high-risk feet and the prevention of ulcers.This manuscript covers the disciplines of internal medicine,surgical,nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot. | Aiping Wang Guozhong Lv Xingbo Cheng Xianghua Ma Wei Wang Jianchao Gui JiHu Meng Lu Guoping Chu Jin’an Chen Hao Zhang Yiqiu Jiang Yuedong Chen Wengbo Yang Lin Jiang Houfa Geng Rendong Zheng Yihui Li Wei Feng Boey Johnson Wenjuan Wang Dalong Zhu Yin Hu | 2020 | Burns & Trauma2020，8，1： | 34 |

| 4 | Carbon carry capacity and carbon sequestration potential in China based on an integrated analysis of mature forest biomass显示文摘Forests play an important role in acting as a carbon sink of terrestrial ecosystem.Although global forests have huge carbon carrying capacity(CCC)and carbon sequestration potential(CSP),there were few quantification reports on Chinese forests.We collected and compiled a forest biomass dataset of China,a total of 5841 sites,based on forest inventory and literature search results.From the dataset we extracted 338 sites with forests aged over 80 years,a threshold for defining mature forest,to establish the mature forest biomass dataset.After analyzing the spatial pattern of the carbon density of Chinese mature forests and its controlling factors,we used carbon density of mature forests as the reference level,and conservatively estimated the CCC of the forests in China by interpolation methods of Regression Kriging,Inverse Distance Weighted and Partial Thin Plate Smoothing Spline.Combining with the sixth National Forest Resources Inventory,we also estimated the forest CSP.The results revealed positive relationships between carbon density of mature forests and temperature,precipitation and stand age,and the horizontal and elevational patterns of carbon density of mature forests can be well predicted by temperature and precipitation.The total CCC and CSP of the existing forests are 19.87 and 13.86 Pg C,respectively.Subtropical forests would have more CCC and CSP than other biomes.Consequently,relying on forests to uptake carbon by decreasing disturbance on forests would be an alternative approach for mitigating greenhouse gas concentration effects besides afforestation and reforestation. | LIU Ying Chun YU Gui Rui WANG Qiu Feng ZHANG Yang Jian XU Ze Hong | 2014 | Science China(Life Sciences)2014，57，12： | 15 |
| 5 | Preliminary study on assessment of nutrient transport in the Taihu Basin based on SWAT modeling显示文摘With the Taihu Basin as a study area, using the spatially distributed and mechanism-based SWAT model, preliminary simulations of nutrient transport in the Taihu Basin during the period of 1995~2002 has been carried out. The topography, soil, meteorology and land use with industrial point pollution discharge, the loss of agricultural fertilizers, urban sewerage, and livestock drainages were all considered in the boundary conditions of the simulations. The model was calibrated and validated against water quality monitoring data from 2001 to 2002. The results show that the annual total productions of nitrogen (TN) and phosphorus (TP) into Lake Taihu are 40000t and 2000t respectively. Nutrient from the Huxi Region is a major resource for Lake Taihu. The non-point source (surface source) pollution is the main form of catchment sources of nutrients into Lake Taihu,occupied TN 53% and TP 56% respectively. TN and TP nutrients from industrial point pollution discharge are 30% and 16%, and sewerage in both forms of point source and non-point source are TN 31% and TP 47%. Both the loss of agricultural fertilizers and livestock drainages from the catchment should be paid more attention as an important nutrient source. The results also show that SWAT is an effective model for the simulation of temporally and spatially nutrient changes and for the assessment of the trends in a catchment scale. | LAI Geying, YU Ge & GUI Feng Nanjing Institute of Geography & Limnology, Chinese Academy of Sciences, Nanjing 210008, China The Graduate School of the Chinese Academy of Sciences, Beijing 100039, China Key Lab of Poyang Lake Ecological Environment and Resource Development, Jiangxi Normal University, Nanchang 330027, China | 2006 | Science China Earth Sciences2006，49，z1： | 11 |
| 6 | Aerodynamic configuration optimization by the integration of aerodynamics, aerothermodynamics and trajectory for hypersonic vehicles显示文摘The problem of aerodynamic configuration design optimization is a multidisciplinary design optimization(MDO) problem, and recently the MDO method is widely adopted in the field of hypersonic vehicle configuration design. From the aerodynamic point of view, the aerodynamics, aerothermodynamics and trajectory are considered in this paper. Generally speaking, the aerodynamic characteristics, aerodynamic heating and trajectory are determined by the aerodynamic configuration and the design of flight trajectory. The design method considering these three disciplines is proposed. The parametric geometrical configurations are proposed, and the aerodynamic characteristics are predicted by the rapid and effective engineering method. The optimization of aerodynamic configuration considering the integration of aerodynamics,aerothermodynamics and trajectory is investigated based on the parametric geometrical configuration. Maximum lift-to-drag ratio, maximum range of the trajectory and minimum total heat load of the stagnation point are chosen as the three optimal goals. The detailed research indicates that the optimal configurations and trajectories with different weighting factors can be obtained by the optimization, and there are obvious differences between them. The optimal configuration and flight trajectory obtained by the optimization can be used as the feasible schemes in the future work. | Yi Feng Wei Tang Yewei Gui | 2014 | Chinese Science Bulletin2014，59，33： | 8 |

| 8 | A novel ubiquitin carboxyl terminal hydroase is involved in toad oocyte maturation显示文摘p28, a 28kD protein from toad (Bufo bufo gargarizans) oocytes, was identified by using p13suc1-agaroseaffinity chromatography. Sequence homology analysis of the full-length cDNA of p28 (Gene Bank accessionnumber: AF 314091) indicated that it encodes a protein containing 224 amino-acids with about 55% iden-tities and more than 70% positives to human, rat or mouse UCH-L1, and contains homological functionaldomains of UCH family. Anti-p28 monoclonal antibody, on injecting into the oocytes, could inhibit theprogesterone-induced resumption of meiotic division in a dose-dependent manner. The recombinant proteinp28 showed similar SDS/PAGE behaviors to the native one, and promoted ubiquitin ethyl ester hydrolysis,a classical catalytic reaction for ubiquitin carboxyl terminai hydrolases (UCHs). The results in this paperreveal that a novel protein, p28, exists in the toad oocytes, is a UCH L1 homolog, was engaged in theprocess of progesterone-induced oocyte maturation possibly through an involvement in protein turnover anddegradation. | ZHAO GUI SUN1,2,3,*, WEI HUA KONG2,*, YAN JUN ZHANG2, SHAN YAN1, JI NING LU1, ZHENG GU1, FENG LIN1, JIA KE TSO1,**1 National Laboratory of Contraceptives and Devices Research, Shanghai Institute of Planned ParenthoodResearch, Shanghai 200032, China2 Colle | 2002 | Cell Research2002，12，4： | 8 |
| 9 | 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 |
| 10 | Effects of PM2.5 Exposure in Different Air Quality Grades on Daily Outpatient Visits for Childhood Asthma in Shijiazhuang, China显示文摘Asthma is a common chronic inflammatory disorder that is more prevalent in children than in adults. China has seen an increasing prevalence of childhood asthma in recent decades[1]. Earlier studies have shown that air particulate matter (PM), particularly fine particulate matter (PM2.5)[2], is an important factor triggering childhood asthma. Since national PM2.5 data were not available until 2013, the effects of PM2.5 on childhood asthma are less known, and most of the related research has been conducted primarily in some metropolises in China. Moreover, the majority of these studies focus on the impact of a unit increase (1 or 10 μg/m3) or an interquartile range increase in PM2.5 on childhood asthma based on the same pollutant background concentrations. Assessment of the impact of air quality grades (AQGs) based on PM2.5 concentration related to health effects is rarely considered[3]. Thus, the purpose of this study is to confirm the effects of PM2.5 on daily outpatient visits for childhood asthma in Shijiazhuang, a heavily polluted city with a high prevalence of childhood asthma in China, for the period 2013-2015, and to evaluate the association between PM2.5 exposure in different national AQGs and outpatient visits for childhood asthma in this city. | FU Gui Qin JIANG Yan Feng LIU Lan Ping LIU Hua Yue ZHOU Ji CUI Xiao Wei WANG Shi Gong | 2018 | Biomedical and Environmental Sciences2018，31，12： | 7 |
| 11 | Simulation of large-scale numerical substructure in real-time dynamic hybrid testing显示文摘A solution scheme is proposed in this paper for an existing RTDHT system to simulate large-scale finite element(FE) numerical substructures. The analysis of the FE numerical substructure is split into response analysis and signal generation tasks, and executed in two different target computers in real-time. One target computer implements the response analysis task, wherein a large time-step is used to solve the FE substructure, and another target computer implements the signal generation task, wherein an interpolation program is used to generate control signals in a small time-step to meet the input demand of the controller. By using this strategy, the scale of the FE numerical substructure simulation may be increased significantly. The proposed scheme is initially verified by two FE numerical substructure models with 98 and 1240 degrees of freedom(DOFs). Thereafter, RTDHTs of a single frame-foundation structure are implemented where the foundation, considered as the numerical substructure, is simulated by the FE model with 1240 DOFs. Good agreements between the results of the RTDHT and those from the FE analysis in ABAQUS are obtained. | Zhu Fei Wang Jinting Jin Feng Zhou Mengxia Gui Yao | 2014 | Earthquake Engineering and Engineering Vibration2014，13，4： | 7 |
| 12 | Shear wave elastography results correlate with liver fibrosis histology and liver function reserve显示文摘AIM: To evaluate the correlation of shear wave elastography(SWE) results with liver fibrosis histology and quantitative function reserve.METHODS: Weekly subcutaneous injection of 60% carbon tetrachloride(1.5 m L/kg) was given to 12 canines for 24 wk to induce experimental liver fibrosis, with olive oil given to 2 control canines. At 24 wk, liver condition was evaluated using clinical biochemistry assays, SWE imaging, lidocaine metabolite monoethylglycine-xylidide(MEGX) test, and histologic fibrosis grading. Clinical biochemistry assays were performed at the institutional central laboratory for routine liver function evaluation. Liver stiffness was measured in triplicate from three different intercostal spaces and expressed as mean liver stiffness modulus(LSM). Plasma concentrations of lidocaine and its metabolite MEGX were determined using high-performance liquid chromatography repeated in duplicate. Liver biopsy samples were fixed in 10% formaldehyde, and liver fibrosis was graded using the modified histological activity index Knodell score(F0-F4). Correlations among histologic grading, LSM, and MEGX measures were analyzed with the Pearson linear correlation coefficient.RESULTS: At 24 wk liver fibrosis histologic grading was as follows: F0, n = 2(control); F1, n = 0; F2, n = 3; F3, n = 7; and F4, n = 2. SWE LSM was positively correlated with histologic grading(r = 0.835, P < 0.001). Specifically, the F4 group had a significantly higher elastic modulus than the F3, F2, and F0 groups(P = 0.002, P = 0.003, and P = 0.006, respectively), and the F3 group also had a significantly higher modulus than the control F0 group(P = 0.039). LSM was negatively associated with plasma MEGX concentrations at 30 min(r =-0.642; P = 0.013) and 60 min(r =-0.651; P = 0.012), time to ? of the maximum concentration(r =-0.538; P = 0.047), and the area under the curve(r =-0.636; P = 0.014). Multiple comparisons showed identical differences in these three measures: significantly lower with F4(P = 0.037) and F3(P = 0.032) as compared to F0 and significantly lower with F4 as compared to F2(P = 0.032).CONCLUSION: SWE LSM shows a good correlation with histologic fibrosis grading and pharmacologic quantitative liver function reserve in experimental severe fibrosis and cirrhosis. | Yan-Hong Feng Xiang-Dong Hu Lin Zhai Ji-Bin Liu Lan-Yan Qiu Yuan Zu Si Liang Yu Gui Lin-Xue Qian | 2016 | World Journal of Gastroenterology2016，22，17： | 7 |

| 15 | Privacy Quantification Model Based on the Bayes Conditional Risk in Location-Based Services显示文摘The widespread use of Location-Based Services(LBSs),which allows untrusted service providers to collect large quantities of information regarding users’locations,has raised serious privacy concerns.In response to these issues,a variety of LBS Privacy Protection Mechanisms(LPPMs)have been recently proposed.However,evaluating these LPPMs remains problematic because of the absence of a generic adversarial model for most existing privacy metrics.In particular,the relationships between these metrics have not been examined in depth under a common adversarial model,leading to a possible selection of the inappropriate metric,which runs the risk of wrongly evaluating LPPMs.In this paper,we address these issues by proposing a privacy quantification model,which is based on Bayes conditional privacy,to specify a general adversarial model.This model employs a general definition of conditional privacy regarding the adversary’s estimation error to compare the different LBS privacy metrics.Moreover,we present a theoretical analysis for specifying how to connect our metric with other popular LBS privacy metrics.We show that our privacy quantification model permits interpretation and comparison of various popular LBS privacy metrics under a common perspective.Our results contribute to a better understanding of how privacy properties can be measured,as well as to the better selection of the most appropriate metric for any given LBS application. | Xuejun Zhang Xiaolin Gui Feng Tian Si Yu Jian An | 2014 | Tsinghua Science and Technology2014，19，5： | 6 |
| 16 | Methylenetetrahydrofolate reductase C677T and A1298C polymorphisms and gastric cancer susceptibility显示文摘AIM: To identify the association between methylenetetrahydrofolate reductase(MTHFR) polymorphisms and gastric cancer(GC) susceptibility.METHODS: Systematic searches were performed on the electronic databases PubMed, ISI, Web of knowledge, CNKI and Wanfang, as well as manual searching of the references of the identified articles. A total of 26 papers were included in this meta-analysis. Overall and subgroup analyses were performed. Odds ratio(OR) and 95%CI were used to evaluate the associations between MTHFR polymorphisms and GC risk. The I2 statistics were used to evaluate between-study heterogeneity. Sensitivity analysis was also performed.RESULTS: Increased risk was found for the MTHFRC677T polymorphism under four genetic models(TT + CT vs CC: OR = 1.23, P = 0.002; T vs C: OR = 1.15, P = 0.001; TT vs CC: OR = 1.37, P = 0.0005; TT vs CT + CC: OR = 1.17, P = 0.0008). Subgroup analysis by ethnicity suggested that C677 T polymorphism conferred a risk of GC in eastern but not in western populations. Stratification by tumor site showed an association between the C677 T polymorphism and gastric cardia cancer and non-cardia GC in the worldwide population and in eastern populations. Regardless of comparisons with controls or diffuse-type GC, a positive association was found for the C677 T polymorphism and an increased risk of intestinal-type GC in the whole population and in western populations. With regard to the A1298 C polymorphism, we found that genotype CC was significantly decreased and conferred protection against GC in eastern populations(CC vs AA: OR = 0.44, P = 0.03; CC vs AC + AA: OR = 0.46, P = 0.04). CONCLUSION: MTHFR C677 T polymorphism is a risk factor for GC, and the A1298 C polymorphism may be a protective factor against GC in eastern populations. | Lei-Zhou Xia Yi Liu Xiao-Zhou Xu Peng-Cheng Jiang Gui Ma Xue-Feng Bu Yong-Jun Zhang Feng Yu Ke-Sen Xu Hua Li | 2014 | World Journal of Gastroenterology2014，20，32： | 6 |

| 19 | Dynamics of Rodent and Rodent-borne Disease during Construction of the Three Gorges Reservoir from 1997 to 2012显示文摘Objective To investigate the impact of impoundment and active public health interventions on rodent populations and rodent-borne diseases in the Three Gorges reservoir region from 1997 to 2012. Methods Surveillance data from 1997 to 2012 were extracted from the Public Health Surveillance System of The Three Gorges established in 1997. Temporal changes in the incidences of hemorrhagic fever with renal syndrome(HFRS) and leptospirosis, rodent density, pathogen-carrying rates, and their correlations were analyzed. Results The average indoor and outdoor rodent densities decreased overall from 1997 to 2012. The average densities decreased by 47.72%(from 4.38% to 2.29%) and 39.68%(from 4.41% to 2.66%), respectively, after impoundment(2003-2012) compared with before impoundment(1997-2002). The average annual incidence rates of HFRS and leptospirosis were 0.29/100,000 and 0.52/100,000, respectively, and decreased by 85.74%(from 0.68/100,000 to 0.10/100,000) and 95.73%(from 1.47/100,000 to 0.065/100,000), respectively, after impoundment compared with before impoundment. Incidences of HFRS and leptospirosis appear to be positively correlated with rodent density in the reservoir area. Conclusion This study demonstrated that rodent density and incidences of rodent-borne diseases decreased and were maintained at low levels during construction of the Three Gorges dam. Measures that reduce rodent population densities could be effective in controlling rodent-borne diseases during large-scale hydraulic engineering construction. | CHANG Zhao Rui LU Liang MAO De Qiang PAN Hui Ming FENG Lian Gui YANG Xiao Bing LIU Feng Feng HE Yuan Yuan ZHANG Jing YANG Wei Zhong | 2016 | Biomedical and Environmental Sciences2016，29，3： | 5 |
| 20 | Altered Expression of Matrix Metalloproteinases and Tight Junction Proteins in Rats following PEMF-Induced BBB Permeability Change显示文摘Objective To investigate the expression of occludin,ZO‐1,MMP‐2,and MMP‐9 in cerebral microvasculature following Pulse Electromagnetic Field(PEMF) induced BBB permeability change.Methods Sprague‐Dawley rats were randomized into PEMF and sham exposed groups(n=8).After exposure to PEMF at 0.5,1,3,6,and 12 h,BBB permeability was measured by Evans‐Blue extravasation.The expression of occludin,ZO‐1,MMP‐2,and MMP‐9 were detected by real‐time quantitative reverse transcriptase PCR and western blotting.MMP‐2 and MMP‐9 activity were detected by EnzChek gelatinase assay.Results Compared with the sham group,PEMF exposure led to increased permeability of the BBB to EB,which was prolonged after exposure.BBB permeability became progressively more severe,and recovered at 6 h.The gene and protein expression of occludin and ZO‐1 were significantly decreased,while MMP‐2 and MMP‐9 expression were significantly increased after exposure to PEMF.All levels of expression recovered 12 h following PEMF.Conclusion Changes to BBB permeability were related to the alteration expression of tight junction proteins and matrix metalloproteinase after exposure to PEMF. | ZHANG Ya Mei ZHOU Yan QIU Lian Bo DING Gui Rong PANG Xiao Feng | 2012 | Biomedical and Environmental Sciences2012，25，2： | 5 |
