| 3 | Environmental and technological effects on ancient social evolution at different spatial scales显示文摘The rise and fall of ancient cultures and civilizations is a hotly debated topic that has generated disagreements and disputes. In this paper we summarize some case studies on the abandonment of ancient sites, the prosperity and collapse of ancient cultures, and demographic changes, as well as the influence of environment and technology during the prehistoric and historic periods. We then suggest that the dominant influencing factors for the evolution of ancient societies vary by spatial scale.At the local scale, sudden disasters are critical factors leading to the destruction and abandonment of large settlements. On a regional scale, climatic variations(e.g., droughts or cold events lasting for decades or centuries) are important factors that induce the collapse of ancient civilizations and mass migrations, while an enduring and stable optimal climate facilitated the prosperity of ancient civilizations. On a global scale, major technological innovations and their dispersion lasting for centuries and even millennia are major catalysts for population growth and social development. Lastly, we illustrate a possible mechanism under which environmental and technological factors played a critical role in ancient human survival and social evolution on different spatial scales. | DONG GuangHui LIU FengWen CHEN FaHu | 2017 | Science China Earth Sciences2017，60，12： | 10 |
| 4 | Multiple evidences indicate no relationship between prehistoric disasters in Lajia site and outburst flood in upper Yellow River valley, China显示文摘All around the world, ancient legends exist about the Great Flood, and the influence of the Great Flood in human evolutionary history is a hotly debated topic. In China, the legend of the prehistoric Great Flood and Yu the Great's flood control has a long history and is considered to be closely linked to the establishment of the Xia Dynasty. However, there is a lack of solid scientific evidence. Against this issue, some scholars have proposed that an earthquake around 1920 BCE in the Guanting Basin along the upper reaches of the Yellow River led to the creation of a lake by damming in the Jishi Gorge and that the outburst of water from that lake led to the massive flood in the Yellow River region. These studies provided new scientific evidence for the Chinese legend. In this paper, we date skeletal samples embedded in earthquake sand blasting from the Lajia site, analyze remains from natural disasters(such as earthquakes and floods) and also archaeological remains. In addition, we compared the skeletal samples dating with that of sediments from the dammed-up lake. Our results are inconsistent with those of previous scholars. The earthquake at the Lajia site occurred no earlier than 1800 BCE, and the dammed-up lake in Jishi Gorge had disappeared by 3600 BCE. Thus, the formation and outburst of the dammed lake, the sudden death of ancient humans at the Lajia site and the ancient earthquake were independent events occurring at different times. In addition, the massive flood in the upper reaches of the Yellow River did not actually happen. Thus, we argue against and invalidate the hypothesis that the massive flood was related to Yu the Great's flood control and the establishment of the Xia Dynasty. | DONG GuangHui ZHANG FanYu LIU FengWen ZHANG DongJu ZHOU AiFeng YANG YiShi WANG GongHui | 2018 | Science China Earth Sciences2018，61，4： | 7 |
| 5 | Prehistoric agriculture development in the Yunnan-Guizhou Plateau, southwest China: Archaeobotanical evidence显示文摘The origin, development and expansion of prehistoric agriculture in East Asia have been widely investigated over the past two decades using archaeobotanical analysis from excavated Neolithic and Bronze Age sites. Research on prehistoric agriculture has predominantly focused in the valleys of the Yellow River and the Yangtze River. Agricultural development during the Neolithic and Bronze Age periods in the Yunnan-Guizhou Plateau of southwest China, an important passageway for human migration into Southeast Asia, still remains unclear. In this paper, based on macrofossil and microfossil analysis and radiocarbon dating at the Shilinggang site, we investigate plant subsistence strategies in the Nujiang River valley during the Bronze Age period. Combined with previous archaeobotanical studies in the Yunnan-Guizhou Plateau, we explore agricultural development processes in this area during the Neolithic and Bronze Age. Our results indicate that rice and foxtail millet were cultivated in Shilinggang around 2500 cal a BP. Three phases of prehistoric agricultural development in the Yunnan-Guizhou Plateau can be identified: rice cultivation from 4800–3900 cal a BP, mixed rice and millet crop(foxtail millet and broomcorn millet) cultivation from 3900–3400 cal a BP, and mixed rice, millet crop and wheat cultivation from 3400–2300 cal a BP. The development of agriculture in the Yunnan-Guizhou Plateau during the Neolithic and Bronze Age periods was primarily promoted by prehistoric agriculture expansion across Eurasia, agricultural expansion which was also affected by the topographic and hydrological characteristics of the area. | LI HaiMing ZUO XinXin KANG LiHong REN LeLe LIU FengWen LIU HongGao ZHANG NaiMeng MIN Rui LIU Xu DONG GuangHui | 2016 | Science China Earth Sciences2016，59，8： | 6 |
| 6 | Recent progress in the synthesis of graphene/CNT composites and the energy-related applications显示文摘Graphene and carbon nanotube(CNT) are representative carbon nanomaterials which have aroused numerous research interest due to their extraordinary material properties and promising application potentials,especially in the energy storage and conversion areas.However,the agglomeration happening in these materials has largely blocked their applications.Hybridization of CNT with graphene can,on one hand,prevent the agglomeration behavior,on the other hand,generate a synergistic effect between them with enhanced physical and chemical properties.There have been many studies conducted to find out the suitable approaches to synthesize graphene/CNT composites,and realize the application potentials of these structures.Based on the recent advances,this paper reviews the current research progress that has been achieved in synthesizing graphene/CNT composites,and the energy-related applications.Through this review,we aim at stimulating more significant research on this subject. | Xin Wu Fengwen Mu Haiyan Zhao | 2020 | Journal of Materials Science & Technology2020，52，20： | 6 |

| 8 | Detecting anthropogenic impact on forest succession from the perspective of wood exploitation on the northeast Tibetan Plateau during the late prehistoric period显示文摘Human activities are usually considered to have had impacts on forest degradation and/or changes of forest composition in the past.The Tibetan Plateau,an environmentally sensitive area,has witnessed a high intensity of human activities since the late Neolithic,but the evidence is still incomplete concerning how human activities affected the environment,especially vegetation changes.This may result,in part,from the fact that research on prehistoric wood utilization by humans in the northeast Tibetan Plateau(NETP)is scarce,especially from the perspective of charcoal analysis,which is an archaeological index directly related to human activities.To fill this gap,we report new data here concerning charcoal analysis from 24 archaeological sites dated 5200–2300 a BP in the NETP,where this period saw remarkable environmental and social changes.By coupling the results with published paleoenvironment records(especially pollen),we aim to explore the utilization of wood and its spatial-temporal changes,as well as the anthropogenic impacts on past forest dynamics in the NETP.The results suggest that the wood resources collected by humans were mainly needleleaf trees(Picea L.and Pinus L.),broadleaved trees(Populus L.,Salix L.,and Betula)as well as shrubs(Hippophae L.and Tamarix L.),and that these were distributed around the human habitation areas.There was a clear spatial difference in the woody assemblage collected by humans in the period 3600–2300 a BP.This was likely related to the diversity of natural environments in local areas,but there was an abnormal spatial pattern of forest composition with broadleaved trees dominant above 2500 masl caused not by climate change,but by the rapid increase of human settlement and wood collection in high altitude areas of the NETP since 3600 a BP. | Fengwen LIU Shanjia ZHANG Hucai ZHANG Guanghui DONG | 2022 | Science China Earth Sciences2022，65，11： | 3 |
| 9 | Randomized controlled study of a diagnosis and treatment plan for moderate coronavirus disease 2019 that integrates Traditional Chinese and Western Medicine显示文摘OBJECTIVE:To investigate the clinical efficacy and safety of a diagnosis and treatment plan for moderate coronavirus disease 2019(COVID-19)that integrates traditional Chinese(TCM)and western medicine.METHODS:One hundred twenty patients with moderate COVID-19 were randomized 1∶2 to the control group(n=40)and experimental group(n=80).Both groups received conventional western medicine treatment,and the experimental group also received TCM decoction.Over a 2-week period from diagnosis,we observed the time to clinical recovery(TTCR),rate of improvement on lung computed tomography(CT)imaging,time to defervescence,cough remission time,hospital discharge rate,average hospitalization stay,modified Medical Research Council(m MRC)scale score,clinical cure rate,laboratory findings,incidence of progression to severe or critical disease,and adverse events.RESULTS:Among 120 enrolled patients,108 completed the study.The baseline data did not differ between the experimental and control groups(all P>0.05).After treatment,the TTCR,rate of lung CT imaging improvement,time to defervescence,cough remission time,hospital discharge rate,average hospitalization stay(among discharged patients),m MRC scale score,clinical cure rate,and rates of normal values for laboratory findings were better in the experimental group than in the control group(P<0.05 or<0.01).The incidence of progression to severe or critical disease and the incidence of adverse events did not differ between the two groups(P>0.05).CONCLUSION:The diagnosis and treatment plan integrating Chinese and western medicine showed improved clinical efficacy compared with western medicine alone for patients with moderate COVID-19 and is worthy of clinical promotion and application. | XIA Wenguang ZHENG Chanjuan ZHANG Jixian HUANG Min LI Qinglin DUAN Can LI Zhengliang FAN Cunyu ZOU Yilong XU Bo YANG Fengwen LIU Qingquan | 2022 | Journal of Traditional Chinese Medicine2022，42，2： | 2 |

| 14 | A fully biodegradable polydioxanone occluder for ventricle septal defect closure显示文摘Ventricular septal defect(VSD)is one of the commonest congenital heart diseases(CHDs).Current occluders for VSD treatment are mainly made of nitinol,which has the risk of nickel allergy,persistent myocardial abrasion and fatal arrythmia.Herein,a fully biodegradable polydioxanone(PDO)occluder equipped with a shape line and poly-L-lactic acid PLLA membranes is developed for VSD closure without the addition of metal marker.PDO occluder showed great mechanical strength,fatigue resistance,geometry fitness,biocompatibility and degradability.In a rat subcutaneous implantation model,PDO filaments significantly alleviated inflammation response,mitigated fibrosis and promoted endothelialization compared with nitinol.The safety and efficacy of PDO occluder were confirmed in a canine VSD model with 3-year follow-up,demonstrating the biodegradable PDO occluder could not only effectively repair VSD,induce cardiac remodeling but also address the complications associated with metal occluders.Furthermore,a pilot clinical trial with five VSD patients indicated that all the occluders were successfully implanted under the guidance of echocardiography and no adverse events occurred during the 3-month follow-up.Collectively,the fully bioresorbable PDO occluder is safe and effective for clinical VSD closure and holds great promise for the treatment of structural CHDs. | Zefu Li Pengxu Kong Xiang Liu Shuyi Feng Wenbin Ouyang Shouzheng Wang Xiaopeng Hu Yongquan Xie Fengwen Zhang Yuxin Zhang Rui Gao Weiwei Wang Xiangbin Pan | 2023 | Bioactive Materials2023，，6： | 1 |
| 15 | Radiation Retinopathy Associated with Central Retinal Vein Occlusion显示文摘Purpose: To report a case of radiation retinopathy associated with central retinal vein occlusion. Methods: The clinical features and fundus fluorescein angiography of this case were analyzed. Results: The patient had been treated with radiotherapy for her nasopharyngeal carcinoma, and presented with sudden visual loss in the left eye. The funduscopic examination and fluorescein angiography showed the features of radiation retinopathy in both eyes, and central retinal vein occlusion in the left eye. Conclusions: Radiation retinopathy can be associated with central retinal vein occlusion in the same eye, and it seems that the endothelial cell loss caused by radiation retinopathy may lead to retinal vein occlusion. | Yan Liu FengWen | 2007 | 眼科学报2007，23，2： | 1 |
