| 1 | Dihydromyricetin inhibits migration and invasion of hepatoma cells through regulation of MMP-9 expression显示文摘AIM:To investigate the effects of dihydromyricetin(DHM)on the migration and invasion of human hepatic cancer cells.METHODS:The hepatoma cell lines SK-Hep-1 and MHCC97L were used in this study.The cells were cultured in RPIM-1640 medium supplemented with 10%fetal bovine serum at 37℃in a humidified 5%CO2incubator.DHM was dissolved in dimethyl sulfoxide and diluted to various concentrations in medium before applying to cells.MTT assays were performed to measure the viability of the cells after DHM treatment.Wound healing and Boyden transwell assays were used to assess cancer cell motility.The invasive capacity of cancer cells was measured using Matrigel-coated transwell chambers.Matrix metalloproteinase(MMP)-2/9 activity was examined by fluorescence analysis.Western blot was carried out to analyze the expression of MMP-2,MMP-9,p-38,JNK,ERK1/2 and PKC-δproteins.All data were analyzed by Student’s t tests in GraphPad prism 5.0software and are presented as mean±SD.RESULTS:DHM was found to strongly inhibit the migration of the hepatoma cell lines SK-Hep-1(without DHM,24 h:120±8μmol/L vs 100μmol/L DHM,24h:65±10μmol/L,P<0.001)and MHCC97L(without DHM,24 h:126±7μmol/L vs 100μmol/L DHM,24h:74±6μmol/L,P<0.001).The invasive capacity of the cells was reduced by DHM treatment(SK-Hep-1cells without DHM,24 h:67±4μmol/L vs 100μmol/L DHM,24 h:9±3μmol/L,P<0.001;MHCC97L cells without DHM,24 h:117±8μmol/L vs 100μmol/L DHM,24 h:45±2μmol/L,P<0.001).MMP2/9 activity was also inhibited by DHM exposure(SK-Hep-1 cells without DHM,24 h:600±26μmol/L vs 100μmol/L DHM,24 h:100±6μmol/L,P<0.001;MHCC97L cells without DHM,24 h:504±32μmol/L vs 100μmol/L DHM 24 h:156±10μmol/L,P<0.001).Western blot analysis showed that DHM decreased the expression level of MMP-9 but had little effect on MMP-2.Further investigation indicated that DHM markedly reduced the phosphorylation levels of p38,ERK1/2 and JNK in a concentration-dependent manner but had no impact on the total protein levels.In addition,PKC-δprotein,a key protein in the regulation of MMP family protein expression,was up-regulated with DHM treatment.CONCLUSION:These findings demonstrate that DHM inhibits the migration and invasion of hepatoma cells and may serve as a potential candidate agent for the prevention of HCC metastasis. | Qing-Yu Zhang Ran Li Guo-Fang Zeng Bin Liu Jie Liu Yang Shu Zhong-Kao Liu Zhi-Dong Qiu Dong-Jun Wang Hui-Lai Miao Ming-Yi Li Run-Zhi Zhu | 2014 | World Journal of Gastroenterology2014,20,29: | 23 |
| 2 | A comparative analysis of five global cropland datasets in China显示文摘Accurate information of cropland area and spatial location is critical for studies of national food security, global environmental change, terrestrial ecosystem geophysics and the geochemical cycle. In this paper, we compared five global cropland datasets in circa 2010 of China from in terms of cropland area and spatial location, including Global Land30, FROM-GLC, Glob Cover, MODIS Collection 5, and MODIS Cropland. The results showed that the accuracies of cropland area and spatial location of Globe Land30 were higher than the other four products. The cropland areas of the five products varied in most of the provinces. Compared with the statistical data, the best goodness of fit was obtained using Globe Land30, followed by MODIS Collection 5 and FROM-GLC, with MODIS Cropland and Glob Cover having the poorer accuracies. Regarding the spatial location of cropland, Globe Land30 achieved the best accuracy, followed by FROM-GLC and MODIS Collection 5, with Glob Cover and MODIS Cropland having the poorer accuracies. In addition, the spatial agreement of the five datasets was reduced from agricultural production area to pastoral area and significantly affected by elevation and slope factors. Although the spatial resolution of MODIS Collection 5 was the lowest, accuracies of the cropland area and spatial location were better than those of Glob Cover and MODIS Cropland. Therefore, high spatial resolution remote sensing images can help to improve the accuracy of the dataset during land cover mapping, while it is also important to select a suitable classification method. Furthermore, in northwestern and southeastern China, spectral mixing pixels are universal because of the complicated landscape and fragmentized topography and result in uncertainty and poor consistency when using the five products. Therefore, these regions require additional attention in future cropland mapping studies. | LU Miao WU WenBin ZHANG Li LIAO AnPing PENG Shu TANG HuaJun | 2016 | Science China(Information Sciences)2016,59,12: | 15 |
| 3 | Numerical study of the effects of local atmospheric circulations on a pollution event over Beijing–Tianjin–Hebei, China显示文摘Currently, the Chinese central government is considering plans to build a trilateral economic sphere in the Bohai Bay area, including Beijing, Tianjin and Hebei(BTH), where haze pollution frequently occurs. To achieve sustainable development, it is necessary to understand the physical mechanism of the haze pollution there. Therefore, the pollutant transport mechanisms of a haze event over the BTH region from 23 to 24 September 2011 were studied using the Weather Research and Forecasting model and the FLEXible-PARTicle dispersion model to understand the effects of the local atmospheric circulations and atmospheric boundary layer structure. Results suggested that the penetration by sea-breeze could strengthen the vertical dispersion by lifting up the planetary boundary layer height(PBLH) and carry the local pollutants to the downstream areas; in the early night, two elevated pollution layers(EPLs) may be generated over the mountain areas: the pollutants in the upper EPL at the altitude of 2–2.5 km were favored to disperse by long-range transport, while the lower EPL at the altitude of 1 km may serve as a reservoir, and the pollutants there could be transported downward and contribute to the surface air pollution.The intensity of the sea–land and mountain–valley breeze circulations played an important role in the vertical transport and distribution of pollutants. It was also found that the diurnal evolution of the PBLH is important for the vertical dispersion of the pollutants,which is strongly affected by the local atmospheric circulations and the distribution of urban areas. | Yucong Miao Shuhua Liu Yijia Zheng Shu Wang Bicheng Chen Hui Zheng Jingchuan Zhao | 2015 | Journal of Environmental Sciences2015,27,4: | 14 |

| 9 | Autophagy activation by Jiang Zhi Granule protects against metabolic stress-induced hepatocyte injury显示文摘AIM To elucidate the potential role of autophagy and the protective effects of Jiang Zhi Granule(JZG) in metabolic stress-induced hepatocyte injury.METHODS An in vitro and in vivo approach was used in this study. Hep G2 cells were incubated in culture medium containing palmitate(PA; 0, 0.1, 0.2, 0.3, 0.4 or 0.5 mmol/L) and treated with or without JZG(100 μg/m L) for 24 h or 48 h, and the progression of autophagy was visualized by stable fluorescence-expressing cell lines LC3 and p62. Western blot analyses were performed to examine the expression of LC3-Ⅱ/LC3-Ⅰ, p62, m TOR and PI3 K, while mitochondrial integrity and oxidative stress were observed by fluorescence staining of JC-1 and reactive oxygen species. C57 BL/6 mice were divided into three groups: control group(n = 10), high fat(HF) group(n = 13) and JZG group(n = 13); and, histological staining was carried out to detect inflammation and lipid content in the liver.RESULTS The cell trauma induced by PA was aggravated in a dose-and time-dependent manner, and hepatic function was improved by JZG. PA had dual effects on autophagy by activating autophagy induction and blocking autophagic flux. The PI3 K-AKT-m TOR signaling pathway and the fusion of isolated hepatic autophagosomes and lysosomes were critically involved in this process. JZG activated autophagy progression by either induction of autophagosomes or co-localization of autophagosomes and lysosomes as well as degradation of autolysosomes to protect against PA-induced hepatocyte injury, and protected mitochondrial integrity against oxidative stress in PA-induced mitochondrial dysfunction. In addition, JZG ameliorated lipid droplets and inflammation induced by HF diet in vivo, leading to improved metabolic disorder and associated liver injury in a mouse model of non-alcoholic fatty liver disease(NAFLD).CONCLUSION Metabolic stress-induced hepatocyte injury exhibited dual effects on autophagy and JZG activated the entire process, resulting in beneficial effects in NAFLD. | Yi-Yuan Zheng Miao Wang Xiang-Bing Shu Pei-Yong Zheng Guang Ji | 2018 | World Journal of Gastroenterology2018,24,9: | 8 |

| 11 | Influence of fuel moisture, charge size, feeding rate and air ventilation conditions on the emissions of PM, OC, EC, parent PAHs, and their derivatives from residential wood combustion显示文摘Controlled combustion experiments were conducted to investigate the influence of fuel charge size, moisture, air ventilation and feeding rate on the emission factors (EFs) of carbonaceous particulate matter, parent polycyclic aromatic hydrocarbons (pPAHs) and their derivatives from residential wood combustion in a typical brick cooking stove. Measured EFs were found to be independent of fuel charge size, but increased with increasing fuel moisture. Pollution emissions from the normal burning under an adequate air supply condition were the lowest for most pollutants, while more pollutants were emitted when an oxygen deficient atmosphere was formed in the stove chamber during fast burning. The impacts of these factors on the size distribution of emitted particles was also studied. Modified combustion efficiency and the four investigated factors explained 68%, 72%, and 64% of total variations in EFs of PM, organic carbon, and oxygenated PAHs, respectively, but only 36%, 38% and 42% of the total variations in EFs of elemental carbon, pPAHs and nitro-PAHs, respectively. | Guofeng Shen Miao Xue Siye Wei Yuanchen Chen Qiuyue Zhao Bing Li Haisuo Wu Shu Tao | 2013 | Journal of Environmental Sciences2013,25,9: | 6 |

| 13 | Enhanced recovery after surgery program in the patients undergoing hepatectomy for benign liver lesions显示文摘Background:Enhanced recovery after surgery(ERAS)has shown effectiveness in terms of reducing the hospital stay and cost.However,the benefit of ERAS in patients undergoing hepatectomy for benign liver lesions is still unclear.Methods:ERAS was implemented in our center since March 1st,2018.From September 2016 to Febru-ary 2018,109 patients were enrolled into the control group,and from March 2018 to June 2019,124 patients were enrolled into the ERAS group.All the indicators related to operation,liver functions,and postoperative outcomes were included in the analysis.Results:The clinicopathologic baselines were similar in these two groups.A significantly higher propor-tion of patients underwent laparoscopic surgery in the ERAS group.On the whole,intraoperative blood loss(100.00 mL vs.200.00 mL,P<0.001),blood transfusion(3.23%vs.10.09%,P=0.033),total bilirubin(17.10μmol/L vs.21.00μmol/L,P=0.041),D-dimer(2.08μg/mL vs.2.57μg/mL,P=0.031),postoperative hospital stay(5.00 d vs.6.00 d,P<0.001),and postoperative morbidity(16.13%vs.32.11%,P=0.008)were significantly shorter or less in the ERAS group than those in the control group.After stratified by operation methods,ERAS group showed significantly shorter postoperative hospital stay in both open and laparoscopic operation(both P<0.001).In patients underwent open surgery,ERAS group demonstrated significantly shorter operative duration(131.76±8.75 min vs.160.73±7.23 min,P=0.016),less intra-operative blood loss(200.00 mL vs.450.00 mL,P=0.008)and less postoperative morbidity(16.00%vs.44.44%,P=0.040).Conclusions:ERAS program may be safe and effective for the patients underwent hepatectomy,especially open surgery,for benign liver lesions. | Jia-Min Zhou Xi-Gan He Miao Wang Yi-Ming Zhao Lian Shu Long-Rong Wang Lu Wang An-Rong Mao | 2020 | Hepatobiliary & Pancreatic Diseases International2020,19,2: | 5 |
| 14 | Emissions of parent, nitrated, and oxygenated polycyclic aromatic hydrocarbons from indoor corn straw burning in normal and controlled combustion conditions显示文摘Emission factors(EFs) of parent polycyclic aromatic hydrocarbons(pPAHs), nitrated PAHs(nPAHs), and oxygenated PAHs(oPAHs)were measured for indoor corn straw burned in a brick cooking stove under diferent burning conditions. The EFs of total 28 pPAHs,6 nPAHs and 4 oPAHs were(7.9 ± 3.4),(6.5 ± 1.6)×10 3, and(6.1 ± 1.4)×10 1mg/kg, respectively. Fuel charge size had insignificant influence on the pollutant emissions. Measured EFs increased significantly in a fast burning due to the oxygen deficient atmosphere formed in the stove chamber. In both restricted and enhanced air supply conditions, the EFs of pPAHs, nPAHs and oPAHs were significantly higher than those measured in normal burning conditions. Though EFs varied among diferent burning conditions, the composition profiles and calculated isomer ratios were similar, without significant diferences. The results from the stepwise regression model showed that fuel burning rate, air supply amount, and modified combustion efciency were the three most significant influencing factors, explaining 72%–85% of the total variations. | Guofeng Shen Miao Xue Siye Wei Yuanchen Chen Bin Wang Rong Wang Yan Lv Huizhong Shen Wei Li Yanyan Zhang Ye Huang Han Chen Wen Wei Qiuyue Zhao Bing Li Haisuo Wu Shu Tao | 2013 | Journal of Environmental Sciences2013,25,10: | 5 |
| 15 | The influence of metabolic syndrome on atrial fibrillation recurrence: five-year outcomes after a single cryoballoon ablation procedure显示文摘BACKGROUND Metabolic syndrome(MetS)has been reported as a risk factor of atrial fibrillation(AF)recurrence after radi-ofrequency catheter ablation.This study aimed to investigate the long-term influence of MetS on paroxysmal AF recurrence after a single cryoballoon ablation procedure,which was scarcely investigated yet in Chinese population.METHODS In total,137 paroxysmal AF patients who had successfully completed a single cryoballoon ablation procedure at Fuwai Hospital,Beijing,China from December 2013 to October 2015 were enrolled.Excepting for patients with AF recurrence,all patients were followed up for no less than five years.Independent predictors of AF recurrence were determined by Cox propor-tional hazards regression analysis.RESULTS Among 137 paroxysmal AF patients,91 patients(66.4%)had successfully achieved overall five-year follow-up after a single cryoballoon ablation procedure,and 44 patients(32.1%)had MetS.Patients with MetS had a significant lower incidence of freedom from AF recurrence than those without MetS(50.0%vs.74.2%,log-rank P<0.01)during the five-year follow-up.MetS(HR=1.95,95%CI:1.069−3.551,P=0.030)was an independent predictor of AF recurrence after adjusting for multiple factors.After the second year post cryoballoon ablation procedure,the recurrence rate of AF gradually increased in patients with MetS,in con-trast,decreased recurrence rate of AF in patients without MetS.CONCLUSIONS MetS is an independent predictor for five-year AF recurrence after a single cryoballoon ablation procedure in paroxysmal AF patients.Combination therapy of AF and MetS may improve the long-term outcomes of AF patients. | Yu XIA Xiao-Feng LI Jun LIU Miao YU Pi-Hua FANG Shu ZHANG | 2021 | Journal of Geriatric Cardiology2021,18,12: | 5 |

| 17 | A Multi-Scale Urban Atmospheric Dispersion Model for Emergency Management显示文摘To assist emergency management planning and prevention in case of hazardous chemical release into the atmosphere, especially in densely built-up regions with large populations, a multi-scale urban atmospheric dispersion model was established.Three numerical dispersion experiments, at horizontal resolutions of 10 m, 50 m and 3000 m, were performed to estimate the adverse effects of toxic chemical release in densely built-up areas. The multi-scale atmospheric dispersion model is composed of the Weather Forecasting and Research(WRF) model, the Open Source Field Operation and Manipulation software package, and a Lagrangian dispersion model. Quantification of the adverse health effects of these chemical release events are given by referring to the U.S. Environmental Protection Agency's Acute Exposure Guideline Levels. The wind fields of the urban-scale case, with 3 km horizontal resolution, were simulated by the Beijing Rapid Update Cycle system, which were utilized by the WRF model. The sub-domain-scale cases took advantage of the computational fluid dynamics method to explicitly consider the effects of buildings. It was found that the multi-scale atmospheric dispersion model is capable of simulating the flow pattern and concentration distribution on different scales, ranging from several meters to kilometers, and can therefore be used to improve the planning of prevention and response programs. | MIAO Yucong LIU Shuhua ZHENG Hui ZHENG Yijia CHEN Bicheng WANG Shu | 2014 | Advances in Atmospheric Sciences2014,31,6: | 4 |
| 18 | Pharmacological actions of miltirone in the modulation of platelet function显示文摘Salvia miltiorrhiza Bunge contains various active constituents, some of which have been developed as commercially available medicine. Moreover, some other ingredients in Salvia miltiorrhiza play roles in anti-platelet activity. The aim of the present study was to investigate the effects and the underlying mechanism of miltirone, a lipophilic compound of Salvia miltiorrhiza Bunge. The ability of miltirone to modulate platelet function was investigated by a variety of in vitro and in vivo experiments. Platelet aggregation and dense granule secretion induced by various agonists were measured with platelet aggregometer. Clot retraction and spreading were imaged by digital camera and fluorescence microscope. Ferric chloride-induced carotid injury model and pulmonary thromboembolism model were used to check miltirone antithrombotic effect in vivo. To elucidate the mechanisms of anti-platelet activity of miltirone, flow cytometry and western blotting were performed. Miltirone (2, 4, 8μM) was shown to suppress platelet aggregation, dense granule, and α granule secretion in a dose-dependent manner. Meanwhile, miltirone inhibited the clot retraction and spreading of washed platelets. It reduced the phosphorylation of PLCγ2, PKC, Akt, GSK3β and ERK1/2 in the downstream signal pathway of collagen receptor. It also reduced the phosphorylation of Src and FAK in the integrin αIIbβ3-mediated “outside-in” signaling, while it did not suppress the phosphorylation of β3. In addition, miltirone prolonged the occlusion time and reduced collagen/epinephrine-induced pulmonary thrombi. Miltirone suppresses platelet “inside-out” and “outside-in” signaling by affecting PLCγ2/PKC/ERK1/2, PI3K/Akt, and Src/FAK signaling. Therefore, miltirone might represent a potential anti-platelet candidate for the prevention of thrombotic disorders. | Wei Song Yuan-yuan Ma Shuo Miao Ru-ping Yang Ying Zhu Dan Shu Meng Lu Rong Ma Zhang-yin Ming | 2019 | Acta Pharmacologica Sinica2019,40,2: | 3 |

| 20 | Influence of fuel mass load,oxygen supply and burning rate on emission factor and size distribution of carbonaceous particulate matter from indoor corn straw burning显示文摘The uncertainty in emission estimation is strongly associated with the variation in emission factor (EF),which could be influenced by a variety of factors such as fuel properties,stove type,fire management and even methods used in measurements.The impacts of these factors are complicated and often interact with each other.Controlled burning experiments were conducted to investigate the influences of fuel mass load,air supply and burning rate on the emissions and size distributions of carbonaceous particulate matter (PM) from indoor corn straw burning in a cooking stove.The results showed that the EFs of PM (EFPM),organic carbon (EFOC) and elemental carbon (EFEC) were independent of the fuel mass load.The differences among them under different burning rates or air supply amounts were also found to be insignificant (p > 0.05) in the tested circumstances.PM from the indoor corn straw burning was dominated by fine PM with diameter less than 2.1 μm,contributing 86.4%±3.9% of the total.The size distribution of PM was influenced by the burning rate and air supply conditions.On average,EF PM,EF OC and EF EC for corn straw burned in a residential cooking stove were (3.84±1.02),(0.846±0.895) and (0.391±0.350) g/kg,respectively.EF PM,EF OC and EF EC were found to be positively correlated with each other (p < 0.05),but they were not significantly correlated with the EF of co-emitted CO,suggesting that special attention should be paid to the use of CO as a surrogate for other incomplete combustion pollutants. | Guofeng Shen Miao Xue Siye Wei Yuanchen Chen Bin Wang Rong Wang Huizhong Shen Wei Li Yanyan Zhang Ye Huang Han Chen Wen Wei Qiuyue Zhao Bin Li Haisuo Wu Shu Tao | 2013 | Journal of Environmental Sciences2013,25,3: | 3 |
