| 1 | Terrestrial vegetation carbon sinks in China,1981―2000显示文摘Using China's ground observations, e.g., forest inventory, grassland resource, agricultural statistics, climate, and satellite data, we estimate terrestrial vegetation carbon sinks for China's major biomes between 1981 and 2000. The main results are in the following: (1) Forest area and forest biomass car- bon (C) stock increased from 116.5×106 ha and 4.3 Pg C (1 Pg C = 1015 g C) in the early 1980s to 142.8×106 ha and 5.9 Pg C in the early 2000s, respectively. Forest biomass carbon density increased form 36.9 Mg C/ha (1 Mg C = 106 g C) to 41.0 Mg C/ha, with an annual carbon sequestration rate of 0.075 Pg C/a. Grassland, shrub, and crop biomass sequestrate carbon at annual rates of 0.007 Pg C/a, 0.014― 0.024 Pg C/a, and 0.0125―0.0143 Pg C/a, respectively. (2) The total terrestrial vegetation C sink in China is in a range of 0.096―0.106 Pg C/a between 1981 and 2000, accounting for 14.6%―16.1% of carbon dioxide (CO2) emitted by China's industry in the same period. In addition, soil carbon sink is estimated at 0.04―0.07 Pg C/a. Accordingly, carbon sequestration by China's terrestrial ecosystems (vegetation and soil) offsets 20.8%―26.8% of its industrial CO2 emission for the study period. (3) Considerable uncertainties exist in the present study, especially in the estimation of soil carbon sinks, and need further intensive investigation in the future. | FANG JingYun GUO ZhaoDi PIAO ShiLong CHEN AnPing | 2007 | Science China Earth Sciences2007,50,9: | 188 |
| 2 | Increasing terrestrial vegetation activity in China, 1982—1999显示文摘Variations in vegetation activity during the past 18 years in China were investigated using the normalized difference vegetation index (NDVI) derived from the 3rd generation time series dataset of NOAA-AVHRR from 1982 to 1999. In order to eliminate the effects of non-vegetation factors, we characterized areas with NDVI < 0.1 as sparsely vegetated areas and areas with NDVI ≥ 0.1 as vegetated areas. The results showed that increasing NDVI trends were evident, to varying extents, in almost all regions in China in the 18 years, indicating that vegetation activity has been rising in recent years in these regions. Compared to the early 1980s, the vegetated area increased by 3.5% by the late 1990s, while the sparsely vegetated area declined by 18.1% in the same period. The national total mean annual NDVI increased by 7.4% during the study period. Extended growing seasons and increased plant growth rates ac-counted for the bulk of these increases, while increases in temperature and summer rainfall, and strengthening agricultural activity were also likely important factors. NDVI changes in China ex-hibited relatively large spatial heterogeneity; the eastern coastal regions experienced declining or indiscernibly rising trends, while agricultural regions and western China experienced marked increases. Such a pattern was due primarily to urbanization, agricultural activity, regional climate characteristics, and different vegetation responses to regional climate changes. | FANG Jingyun PIAO Shilong HE Jinsheng MA Wenhong | 2004 | Science China(Life Sciences)2004,47,3: | 109 |
| 3 | Biomass carbon stocks in China's forests between 2000 and 2050:A prediction based on forest biomass-age relationships显示文摘China's forests are characterized by young forest age,low carbon density and a large area of planted forests,and thus have high potential to act as carbon sinks in the future.Using China's national forest inventory data during 1994-1998 and 1999-2003,and direct field measurements,we investigated the relationships between forest biomass density and forest age for 36 major forest types.Statistical approaches and the predicted future forest area from the national forestry development plan were applied to estimate the potential of forest biomass carbon storage in China during 2000-2050.Under an assumption of continuous natural forest growth,China's existing forest biomass carbon(C) stock would increase from 5.86 Pg C(1 Pg=1015 g) in 1999-2003 to 10.23 Pg C in 2050,resulting in a total increase of 4.37 Pg C.Newly planted forests through afforestation and reforestation will sequestrate an additional 2.86 Pg C in biomass.Overall,China's forests will potentially act as a carbon sink for 7.23 Pg C during the period 2000-2050,with an average carbon sink of 0.14 Pg C yr-1.This suggests that China's forests will be a significant carbon sink in the next 50 years. | XU Bing,GUO ZhaoDi,PIAO ShiLong & FANG JingYun* Department of Ecology,College of Urban and Environmental Sciences,and Key Laboratory for Earth Surface Processes of the Ministry of Education,Peking University,Beijing 100871,China | 2010 | Science China(Life Sciences)2010,53,7: | 61 |
| 4 | Disease Risks of Childhood Obesity in China显示文摘Objective To estimate the relative risks of dyslipidemia, hypertension, diabetes mellitus, and metabolic syndromes among overweight and obese Chinese children compared with their normal weight counterparts. Methods Overweight and obesity were defined by age- and sex-specific BMI classification reference for Chinese children and adolescents. Pediatric metabolic syndrome (MetS) and each risk factor for MetS were defined using the criteria for US adolescents. Definition of hyper-TC, LDL, and dyslipidemia for adults was applied as well. General linear model factor analysis and chi-square test were used to compare the difference in metabolic indicators among normal weight, overweight, and obese groups. Multiple logistic regression analysis was performed to estimate the odds ratio of metabolic abnormalities between obesity, overweight, and normal weight children, after adjustment for living area, family economic level, age, sex, and daily exercise time and TV watching time, as well as different dietary indices in the model. Results Significant increases in blood lipids, glucose, and blood pressure were found among overweight and obese children as compared with their counterparts with normal weight. By applying WGOC-recommended BMI classification, the risks for hypertriglyceridemia, low HDL and dyslipidemia among overweight children were 1.9, 1.4, and 1.5 times, and was 3.3, 1.5, and 1.8 times among obese groups compared to their counterparts with normal weight after adjustment for age, sex, region, socioeconomic status, physical activity, and dietary intakes. The overweight and obese children (15-17.9 years) had a high-risk of developing hypertension, which was 2.3 and 2.9times higher than their counterparts with normal weight. Above 90% obese adolescents had abdominal obesity, while less than1% normal weight ones had abdominal obesity. No obese adolescents were free from any risk factors for MetS, while 36.9% of normal weight adolescents were from the risk factors. 83.3% obese boys and all obese girls had metabolic syndrome, while only15.5% normal weight boys and 18.8% normal weight girls had metabolic syndrome. Four risk factors for metabolic syndrome were found in 8.3% obese boys while none in normal weight boys and girls. The prevalence of MetS among normal weight,overweight, and obesity groups was 1.5%, 18.3%, and 38.1% respectively. Conclusion The cardiovascular disease (CVD)risk factors are clustered in obese Chinese children. Our observations strongly suggest that efforts should be made to prevent the onset of overweight and its associated diseases during early childhood. | YAN-PING LI XIAO-GUANG YANG FENG-YING ZHAI JIAN-HUA PIAO WEN-HUA ZHAO JIAN ZHANG GUAN-SHENG MA | 2005 | Biomedical and Environmental Sciences2005,18,6: | 70 |

| 6 | Multispherical interactions and their effects on the Tibetan Plateau's earth system: a review of the recent researches显示文摘The Tibetan Plateau(TP) is a regional Earth system showing very strong interactions among its lithosphere, hydrosphere, cryosphere, biosphere, atmosphere, and anthrosphere. hese interactions manifest TP's impact on surrounding regions and relect TP's response to the global change. Quantifying the multispherical interactions is critically important to understand the TP environment. Our recent years researches including the ongoing program entitled ‘Tibetan Multi-Spheres Interactions and heir Resource-Environment Signiicance(TIMI)', the completed program entitled. ‘Paleo-Altitudes of Tibetan Plateau and Environment(PATE)', as well as the other relating projects have focused on multidisciplinary research approaches and emphasized on three major pathways: Eurasia-Indian plates collision on deep-Earth dynamics, uplit impact on Earth's mantle–crust dynamics, and contemporary interface on land surface and atmospheric dynamics. Our researches have taken in situ measurement as priority and developed several platforms of data acquisition and analysis, including the platforms of water-phase transformations, and ecosystem observations. Our ield investigations have been conducted to obtain data about stratum, paleontology, paleoenvironment, genetic diferentiation of animals and plants. We have developed conceptual and mathematical models for crust uplit formation, paleoclimate, glacial melt,water–air interface lux, vegetation climate, and soil erosion. We have also assessed the anthropogenic impacts on environment. Our researches have achieved new and reliable redating of the mantle–crust interaction and initial formation of the TP, found the interaction between tectonics and uplit of the TP and resultant paleoaltitude acting as a spreading source; discovered the interaction between the westerlies and Indian monsoon acting as a control chain that dominates the TP's contemporary environment. he scientiic results can play fundamental roles in supporting the TP's resource exploration and societal sustainable development. | Tandong Yao Fuyuan Wu Lin Ding Jimin Sun Liping Zhu Shilong Piao Tao Deng Xijun Ni Hongbo Zheng Hua Ouyang | 2015 | National Science Review2015,2,4: | 35 |
| 7 | Wet Cupping Therapy Improves Local Blood Perfusion and Analgesic Effects in Patients with Nerve-Root Type Cervical Spondylosis显示文摘Objective: To observe wet cupping therapy(WCT) on local blood perfusion and analgesic effects in patients with nerve-root type cervical spondylosis(NT-CS). Methods: Fifty-seven NT-CS patients were randomly divided into WCT group and Jiaji acupoint-acupuncture(JA) group according a random number table. WCT group(30 cases) was treated with WCT for 10 min, and JA group(27 cases) was treated with acupuncture for 10 min. The treatment efficacies were evaluated with a Visual Analogue Scale(VAS). Blood perfusion at Dazhui(GV 14) and Jianjing(GB 21) acupoints(affected side) was observed with a laser speckle flowmetry, and its variations before and after treatment in both groups were compared as well. Results: In both groups, the VAS scores significantly decreased after the intervention(P<0.01), while the blood perfusion at the two acupoints significantly increased after intervention(P<0.05); however, the increasement magnitude caused by WCT was obvious compared with JA(P<0.05). Conclusion: WCT could improve analgesic effects in patients with NT-CS, which might be related to increasing local blood perfusion of acupunct points. | MENG Xiang-wen WANG Ying PIAO Sheng-ai LV Wen-tao ZHU Cheng-hui MU Ming-yuan LI Dan-dan LIU Hua-peng GUO Yi | 2018 | Chinese Journal of Integrative Medicine2018,24,11: | 33 |
| 8 | Clinical short-term results of radiofrequency ablation in liver cancers显示文摘AIM: To study local therapeutic efficacy, side effects, andcomplications of radiofrequency ablation (RFA), whichis emerging as a new method for the treatment ofpatients with hepatocellular carcinoma (HCC) withcirrhosis or chronic hepatitis and metastatic liver cancer.METHODS: Thirty-six patients with primary andsecondary liver cancers (21 with primaryhepatocellular carcinoma, 12 with colorectal cancerliver metastases and 3 with other malignant livermetastases), which were considered not suitable forcurative resection, were include in this study. Theywere treated either with RFA (RITA2000, MountainView, California, USA) percutaneously (n=20)orintraoperatively (n=16).The procedures wereperformed using the ultrasound guidance. The qualityof RFA were based on monitoring of equipments andsubject feeling of the practitioners. Patients treatedwith RFA was followed according to clinical findings,radiographic images, and tumor markers.RESULTS: Thirty-six patients underwent RFA for 48nodules. RFA was used to treat an average 1.3 lesionsper patient, and the median size of treated lesions was2.5 cm (range, 0.5-9 cm). The average hospital staywas 5.6 days overall (2.8 days for percutaneous casesand 7.9 days for open operations). Seven patientsunderwent a second RFA procedure (sequentialablations). Sixteen HCC patients with a high level ofalpha fetoprotein (AFP) and 9 colorectal cancer livermetastases patients with a high level of serumcarcinoembryonic antigen (CEA) have a great reductionbenefited from RFA. Four (11.1 %) patients hadcomplications: one skin burn; one postoperativehemorrhage; one cholecystitis and one hepatic abscessassociated with percutaneous ablations of a largelesion. There were 4 deaths: 3 patients died from localand system diseases (1 at 7 month, 1 at 9 month, and 1at 12 month), 1 patients died from cardiovascular shock,but no RFA-related death. At a median follow-up of 10months (range, 1-24 months), 6 patients (16.7 %) hadrecurrences at an RFA site, and 20 patients (56.7 %)remained clinically free of disease.CONCLUSION: RF ablation appears to be an effective,safe, and relatively simple procedure for the treatmentof unresectable liver cancers. The rate and severity ofcomplications appear acceptable. However, furtherstudy is necessary to assess combination with othertherapies, long-term recurrence rates and effect onoverall survival. | Hong-Chi Jiang Lian-Xin Liu Da-Xun Piao Jun Xu An-Long Zhu Wei-Hui Zhang Lin-Feng Wu Department of Surgery,the First Clinical College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Min Zheng Department of Ultrasound Diagnosis,the First Clinical College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Shu-Yi Qi Second Inpatient Department,the First Clinical College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China | 2002 | World Journal of Gastroenterology2002,8,4: | 33 |

| 11 | Ginsenoside Rgl protects against ischemic/reperfusioninduced neuronal injury through miR-144/Nrf2/ARE pathway显示文摘Ginsenoside Rg1 (Rg1),a saponin extracted from Panax ginseng,has been well documented to be effective against ischemic/ reperfusion (I/R)neuronal injury.However,the underlying mechanisms remain obscure.In the present study,we investigated the roles of Nrf2 and miR-144 in the protective effects of Rgl against I/R-induced neuronal injury.In OGD/R-treated PC12 cells,Rgl (0.01-1 μmol/L)dose-dependently attenuated the cell injury accompanied by prolonging nuclear accumulation of Nrf2,enhancing the transcriptional activity of Nrf2,as well as promoting the expression of ARE-target genes.The activation of the Nrf2/ARE pathway by Rgl was independent of disassociation with Keapl,but resulted from post-translational regulations.Knockdown of Nrf2 abolished all the protective changes of Rgl in OG-D/R-treated PC12 cells.Furthermore,Rgl treatment significantly decreased the expression of miR-144,which downregulated Nrf2 production by targeting its 3'-untranlated region after OGD/R.Knockdown of Nrf2 had no effect on the expression of miR-144,suggesting that miR-144 was an upstream regulator of Nrf2.We revealed that there was a direct binding between Nrf2 and miR-144 in PC12 cells.Application of anti-miR-144 occluded the activation of the Nrf2/ ARE pathway by Rgl in OGD/R-treated PC12 cells.In tMCAO rats,administration of Rgl (20 mg/kg).significantly alleviated ischemic injury,and activated Nff2/ARE pathway.The protective effects of Rgl were abolished by injecting of AAV-HIF-miR-144-shRNA into the predicted ischemic penumbra.In conclusion,our results demonstrate that Rgl alleviates oxidative,stress after I/R through inhibiting miR-144 activity and subsequently promoting the Nrf2/ARE pathway at the post-translational-level. | Shi-feng Chu Zhao Zhang Xin Zhou Wen-bin He Chen Chen Piao Luo Dan-dan Liu Qi-di Ai Hai-fan Gong Zhen-zhen Wang Hong-shuo Sun Zhong-ping Feng Nai-hong Chen | 2019 | Acta Pharmacologica Sinica2019,40,1: | 30 |
| 12 | Estimation of China’s terrestrial ecosystem carbon sink:Methods,progress and prospects显示文摘China announced its national goal to reach the peak of carbon emission by 2030 and achieve carbon neutrality by 2060,during the General Assembly of the United Nations in September 2020.In this context,the potential of the carbon sink in China’s terrestrial ecosystems to mitigate anthropogenic carbon emissions has attracted unprecedented attention from scientific communities,policy makers and the public.Here,we reviewed the assessments on China’s terrestrial ecosystem carbon sink,with focus on the principles,frameworks and methods of terrestrial ecosystem carbon sink estimates,as well as the recent progress and existing problems.Looking forward,we identified critical issues for improving the accuracy and precision of China’s terrestrial ecosystem carbon sink,in order to serve the more realistic policy making in pathways to achieve carbon neutrality for China. | Shilong PIAO Yue HE Xuhui WANG Fahu CHEN | 2022 | Science China Earth Sciences2022,65,4: | 30 |
| 13 | Tetrandrine stimulates the apoptosis of hepatic stellate cells and ameliorates development of fibrosis in a thioacetamide rat model显示文摘AIM: To investigate the therapeutic effect of tetrandrine on liver fibrosis induced by thioacetamide in rats in vivo and in vitro. METHODS: In vitro study: we investigated the effect of tetrandrine on the apoptosis of rat hepatic stellate cells transformed by simian virus 40 (T-HSC/Cl-6), which retains the features of activated cells. In vivo study: hepatic fibrosis was induced in rats by thioacetamide. Tetrandrine was given orally to rats at doses of 5, 10 or 20 mg/kg for 4 wk compared with intraperitoneal injection of interferon-г. RESULTS: In vitro study: 5, 10 or 25 μg/mL of tetrandrine-induced activation of caspase-3 in t-HSC/Cl-6 cells occurred dose-dependently. In vivo study: tetrandrine treatment as well as interferon-г significantly ameliorated the development of fibrosis as determined by lowered serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (T-Bil) and the levels of liver hydroxyproline (Hyp), hyaluronic acid (HA), laminin (LN) and also improved histological findings. The effects of tetrandrine at the concentration of 20 mg/kg were better than the other concentration groups. CONCLUSION: Tetrandrine promotes the apoptosis of activated HSCs in vitro . Tetrandrine administration can prevent liver fibrosis and liver damage induced bythioacetamide in rats in vivo, indicating that it might exert a direct effect on rat HSCs. | Ming-Fu Yin Li-Hua Lian Dong-Ming Piao Ji-Xing Nan | 2007 | World Journal of Gastroenterology2007,13,8: | 25 |
| 14 | Future biomass carbon sequestration capacity of Chinese forests显示文摘Chinese forests, characterized by relatively young stand age, represent a significant biomass carbon(C)sink over the past several decades. Nevertheless, it is unclear how forest biomass C sequestration capacity in China will evolve as forest age, climate and atmospheric CO_2 concentration change continuously. Here,we present a semi-empirical model that incorporates forest age and climatic factors for each forest type to estimate the effects of forest age and climate change on total forest biomass, under three different scenarios based on the fifth phase of the Coupled Model Intercomparison Project(CMIP5). We estimate that age-related forest biomass C sequestration to be 6.69 Pg C(~0.17 Pg C a^(-1)) from the 2000s to the 2040s.Climate change induces a rather weak increase in total forest biomass C sequestration(0.52–0.60 Pg C by the 2040s). We show that rising CO_2 concentrations could further increase the total forest biomass C sequestration by 1.68–3.12 Pg C in the 2040s across all three scenarios. Overall, the total forest biomass in China would increase by 8.89–10.37 Pg C by the end of 2040s. Our findings highlight the benefits of Chinese afforestation programs, continued climate change and increasing CO_2 concentration in sustaining the forest biomass C sink in the near future, and could therefore be useful for designing more realistic climate change mitigation policies such as continuous forestation programs and careful choice of tree species. | Yitong Yao Shilong Piao Tao Wang | 2018 | Science Bulletin2018,63,17: | 25 |
| 15 | Altered trends in carbon uptake in China’s terrestrial ecosystems under the enhanced summer monsoon and warming hiatus显示文摘The carbon budgets in terrestrial ecosystems in China are strongly coupled with climate changes.Over the past decade,China has experienced dramatic climate changes characterized by enhanced summer monsoon and decelerated warming.However,the changes in the trends of terrestrial net ecosystem production(NEP)in China under climate changes are not well documented.Here,we used three ecosystem models to simulate the spatiotemporal variations in China's NEP during 1982–2010 and quantify the contribution of the strengthened summer monsoon and warming hiatus to the NEP variations in four distinct climatic regions of the country.Our results revealed a decadal-scale shift in NEP from a downtrend of–5.95 Tg C/yr^2(reduced sink)during 1982–2000 to an uptrend of 14.22 Tg C/yr^2(enhanced sink)during 2000–10.This shift was essentially induced by the strengthened summer monsoon,which stimulated carbon uptake,and the warming hiatus,which lessened the decrease in the NEP trend.Compared to the contribution of 56.3%by the climate effect,atmospheric CO2 concentration and nitrogen deposition had relatively small contributions(8.6 and 11.3%,respectively)to the shift.In conclusion,within the context of the global-warming hiatus,the strengthening of the summer monsoon is a critical climate factor that enhances carbon uptake in China due to the asymmetric response of photosynthesis and respiration.Our study not only revealed the shift in ecosystem carbon sequestration in China in recent decades,but also provides some insight for understanding ecosystem carbon dynamics in other monsoonal areas. | Honglin He Shaoqiang Wang Li Zhang Junbang Wang Xiaoli Ren Lei Zhou Shilong Piao Hao Yan Weimin Ju Fengxue Gu Shiyong Yu Yuanhe Yang Miaomiao Wang Zhongen Niu Rcmg Ge Huimin Yan Mei Huang Guoyi Zhou Yongfei Bai Zongqiang Xie Zhiyao Tang Bingfang Wu Leiming Zhang Nianpeng He Qiufeng Wang Guirui Yu | 2019 | National Science Review2019,6,3: | 24 |

| 18 | Essential oil and aromatic plants as feed additives in non-ruminant nutrition:a review显示文摘This paper summarizes the current knowledge regarding the possible modes of action and nutritional factors involved in the use of essential oils(EOs) for swine and poultry.EOs have recently attracted increased interest as feed additives to be fed to swine and poultry,possibly replacing the use of antibiotic growth promoters which have been prohibited in the European Union since 2006.In general,EOs enhance the production of digestive secretions and nutrient absorption,reduce pathogenic stress in the gut,exert antioxidant properties and reinforce the animal's immune status,which help to explain the enhanced performance observed in swine and poultry.However,the mechanisms involved in causing this growth promotion are far from being elucidated,since data on the complex gut ecosystem,gut function,in vivo oxidative status and immune system are still lacking.In addition,limited information is available regarding the interaction between EOs and feed ingredients or other feed additives(especially pro- or prebiotics and organic acids).This knowledge may help feed formulators to better utilize EOs when they formulate diets for poultry and swine. | Zhikai Zeng Sai Zhang Hongliang Wang Xiangshu Piao | 2016 | Journal of Animal Science and Biotechnology2016,7,1: | 19 |
| 19 | Regional differences in the timing of recent air warming during the past four decades in China显示文摘Global surface temperature has dramatically increased in the past decades.It is critical to evaluate such a change using appropriate approaches.The previous studies for assessment of the change usually used overall trends of temperature series(i.e.slopes of simple linear regression of temperature versus year based on a least-square analysis) for entire study period.Temperature trends,however,differ among different periods,i.e.there are often breakpoints in the temperature series.Therefore,the overall linear trend of a temperature series may conceal some of the temporal characteristics of the temperature change.To precisely characterize the temporal and spatial patterns of air temperature change in China,we analyze the annual mean temperature series between the year of 1961?2004 for 536 meteorological stations across China,using piecewise linear regression approach.We found remarkable breakpoints in the annual mean temperature during the study period across the country.The annual mean temperature started to increase in 1984 at a rate of 0.058°C/a at the country level.The year when warming started appeared to be gradually later from the north to the south:temperature increased since the 1970s in the north(north of 40°N),and did not rise until the 1980s in most areas of the south(south of 40°N),with warming starting in 1983 in the Tibetan Plateau.The trends in annual mean temperatures showed a large spatial heterogeneity across China:a relatively small rising with a rate of 0.025-0.05°C/a in the Sichuan Basin,Central China and South China;the greatest increase in some parts of northwest China(i.e.Xinjiang) with up to a rate of 0.1°C/a;and rising at a rate of >0.05°C/a for most regions of the country.The feedbacks of cold waves and snow may be responsible for such regional differences in the timing and rates of warming in China. | WANG ShaoPeng WANG ZhiHeng PIAO ShiLong FANG JingYun | 2010 | Chinese Science Bulletin2010,55,19: | 18 |
