| 1 | Linking atmospheric pollution to cryospheric change in the Third Pole region: current progress and future prospects显示文摘The Tibetan Plateau and its surroundings are known as the Third Pole(TP). This region is noted for its high rates of glacier melt and the associated hydrological shifts that affect water supplies in Asia. Atmospheric pollutants contribute to climatic and cryospheric changes through their effects on solar radiation and the albedos of snow and ice surfaces; moreover, the behavior and fates within the cryosphere and environmental impacts of environmental pollutants are topics of increasing concern. In this review, we introduce a coordinated monitoring and research framework and network to link atmospheric pollution and cryospheric changes(APCC) within the TP region. We then provide an up-to-date summary of progress and achievements related to the APCC research framework, including aspects of atmospheric pollution’s composition and concentration, spatial and temporal variations, trans-boundary transport pathways and mechanisms, and effects on the warming of atmosphere and changing in Indian monsoon, as well as melting of glacier and snow cover. We highlight that exogenous air pollutants can enter into the TP’s environments and cause great impacts on regional climatic and environmental changes. At last, we propose future research priorities and map out an extended program at the global scale. The ongoing monitoring activities and research facilitate comprehensive studies of atmosphere–cryosphere interactions, represent one of China’s key research expeditions to the TP and the polar regions and contribute to the global perspective of earth system science. | Shichang Kang Qianggong Zhang Yun Qian Zhenming Ji Chaoliu Li Zhiyuan Cong Yulan Zhang Junming Guo Wentao Du Jie Huang Qinglong You Arnico K.Panday Maheswar Rupakheti Deliang Chen Orjan Gustafsson Mark H.Thiemens Dahe Qin | 2019 | National Science Review2019,6,4: | 35 |

| 3 | Elemental composition of aerosols collected in the glacier area on Nyainqêntanglha Range, Tibetan Plateau, during summer monsoon season显示文摘In order to investigate the elemental composition in atmospheric aerosols and its sources in the glacier area over the Tibetan Plateau (TP), seven totally suspended particle samples were collected continuously at the col of the Zhadang glacier (30°28′N,90°39′E,5800 m a.s.l.), Nyainqêntanglha Range, southern TP, from June to October 2006. Twenty-seven elements (Li, Be, B, Na, Mg, Al, K, Ca, Sc, Ti, V, Fe, Mn, Zn, Ga, As, Rb, Sr, Y, Cd, Cs, Ba, Tl, Pb, Bi, Th, U) were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The result indicates that the concentrations of most elements (especially crustal elements) are lower than values at the Nam Co Station during the same period of 2005, and also much lower than other sites in the TP such as Wudaoliang and Waliguan. This suggests that elemental compositions of aerosols in the Zhadang glacier area may represent the background levels of the middle/upper troposphere over the TP. Crustal enrichment factors (EFs) reveal that several elements (e.g. B, Zn, As, Cd, Pb and Bi) may have anthropogenic sources. The southern TP is mainly influenced by the summer Indian monsoon during the sampling period. Backward air mass trajectory analysis suggests that air masses in the region may originate from South Asia. Therefore, anthropogenic pollutants from South Asia may be transported by the summer Indian monsoon to the region which clearly affects the atmospheric environment in the southern TP during the summer monsoon season. | LI ChaoLiu1,2, KANG ShiChang1,3 & CONG ZhiYuan1,2 1 Nam Co Monitoring and Research Station for Multisphere Interactions, Institute of Tibetan Plateau Research, CAS, Beijing 100085, China 2 Graduate University of Chinese Academy of Sciences, Beijing 100039, China 3 State Key Laboratory of Cryospheric Sciences, CAS, Lanzhou 730000, China | 2007 | Chinese Science Bulletin2007,52,24: | 18 |
| 4 | Quantitative computed tomography analysis for stratifying the severity of Coronavirus Disease 2019显示文摘To examine the feasibility of using a computer tool for stratifying the severity of Coronavirus Disease 2019(COVID-19)based on computed tomography(CT)images.We retrospectively examined 44 confirmed COVID-19 cases.All cases were evaluated separately by radiologists(visually)and through an in-house computer software.The degree of lesions was visually scored by the radiologist,as follows,for each of the 5 lung lobes:0,no lesion present;1,<1/3 involvement;2,>1/3 and<2/3 involvement;and 3,>2/3 involvement.Lesion density was assessed based on the proportion of ground-glass opacity(GGO),consolidation and fibrosis of the lesions.The parameters obtained using the computer tool included lung volume(mL),lesion volume(mL),lesion percentage(%),and mean lesion density(HU)of the whole lung,right lung,left lung,and each lobe.The scores obtained by the radiologists and quantitative results generated by the computer software were tested for correlation.A Chi-square test was used to test the consistency of radiologist-and computer-derived lesion percentage in the right/left lung,upper/lower lobe,and each of the 5 lobes.The results showed a strong to moderate correlation between lesion percentage scores obtained by radiologists and the computer software(r ranged from 0.7679 to 0.8373,P<0.05),and a moderate correlation between the proportion of GGO and mean lesion density(r=-0.5894,P<0.05),and proportion of consolidation and mean lesion density(r=0.6282,P<0.05).Computer-aided quantification showed a statistical significant higher lesion percentage for lower lobes than that assessed by the radiologists(x^2=8.160,P=0.004).Our experiments demonstrated that the computer tool could reliably and accurately assess the severity and distribution of pneumonia on CT scans. | Cong Shen Nan Yu Shubo Cai Jie Zhou Jiexin Sheng Kang Liu Heping Zhou Youmin Guo Gang Niu | 2020 | Journal of Pharmaceutical Analysis2020,10,2: | 13 |
| 5 | A novel superhard tungsten nitride predicted by machine-learning accelerated crystal structure search显示文摘Transition metal nitrides have been suggested to have both high hardness and good thermal stability with large potential application value,but so far stable superhard transition metal nitrides have not been synthesized.Here,with our newly developed machine-learning accelerated crystal structure searching method,we designed a superhard tungsten nitride,h-WN_6,which can be synthesized at pressure around65 GPa and quenchable to ambient pressure.This h-WN_6is constructed with single-bonded armchair-like N_6rings and presents ionic-like features,which can be formulated as W^(2.4+)N_6^(2.4à).It has a band gap of1.6 e V at 0 GPa and exhibits an abnormal gap broadening behavior under pressure.Excitingly,this h-WN_6is found to be the hardest among transition metal nitrides known so far(Vickers hardness around57 GPa)and also has a very high melting temperature(around 1,900 K).Additionally,the good gravimetric(3.1 k J/g)and volumetric(28.0 k J/cm^3)energy densities make this nitrogen-rich compound a potential high-energy-density material.These predictions support the designing rules and may stimulate future experiments to synthesize superhard and high-energy-density material. | Kang Xia Hao Gao Cong Liu Jianan Yuan Jian Sun Hui-Tian Wang Dingyu Xing | 2018 | Science Bulletin2018,63,13: | 11 |

| 7 | Concentration level and distribution of polycyclic aromatic hydrocarbons in soil and grass around Mt. Qomolangma, China显示文摘High mountains may serve as a condenser for persistent organic pollutants. In the present study, soil and grass samples from Mt. Qomolangma region, China were collected from 4600 to 5620 m a.s.l and were analyzed for polycyclic aromatic hydrocarbons (PAHs) to determine if they are concentrated at colder, more elevated sites and to evaluate their possible resources and fractionation. The total PAHs concentration in soil samples was < 600 ng g?1, the critical value to differentiate PAHs levels in remote and urban regions. This implied the PAHs levels at Mt. Qomolangma are relatively low and what one might expect in such a remote region of the world. These low values may represent a soil background for mid-latitude Northern Hemisphere soils away from the direct influence of an anthropogenic source. As for the distribution pattern, the low molecular weight PAHs were prone to accumulate at higher altitude, while the high molecular weight PAHs inversely related or unrelated with elevation. Based on high concentration of phenanthrene at elevated sample site and the ratios of individual PAHs, we deduced that home-heating combustion and vehicle emission may result in the constitution trait of PAHs in this mountain region. Monsoon traveling over India, Pakistan and other countries with dense population may carry contaminant to Mt. Qomolangma region. | WANG XiaoPing YAO TanDong CONG ZhiYuan YAN XinLiang KANG ShiChang ZHANG Yong | 2007 | Chinese Science Bulletin2007,52,10: | 8 |
| 8 | Aerosol characteristics and impacts on weather and climate over the Tibetan Plateau显示文摘With themostmassive snow and ice globally between 60°S and 60°S ,the Tibetan Plateau(TP),also called the third pole of the world,plays significant roles in the weather,climate and lives in South Asia and East Asia and even the world[1–3].Investigating the variation of weather and the climate system over the TP has long been carried out,which is significant for fresh water supplies for over 1.4 billion people in Asia.Actually,the‘Third Pole Environment’program was initiated to call international efforts to understand both climate and environment changes on the plateau[1],which has already shown rapid warming and intensified cryospheric melt and water cycle. | Chuanfeng Zhao Yikun Yang Hao Fan Jianping Huang Yunfei Fu Xiaoye Zhang Shichang Kang Zhiyuan Cong Husi Letu Massimo Menenti | 2020 | National Science Review2020,7,3: | 7 |
| 9 | Seasonal features of aerosol particles recorded in snow from Mt. Qomolangma (Everest) and their environmental implications显示文摘To assess the seasonality of aerosol deposition and anthropogenic eects on central Himalayas, a 1.85-m deep snow pit was dug on the northern slope of Mt. Qomolangma (Everest). Based on the morphology and energy dispersive X-ray (EDX) signal, totally 1500 particles were classed into 7 groups: soot; aluminosilicates; y ash; calcium sulfates; Ca/Mg carbonates; metal oxides; and biological particles and carbon fragments. The size distribution and number fractions of dierent particle groups exhibited distinct seasonal variations between non-monsoon and monsoon periods, which are clearly related to the dierences in air mass pathways. Specifically, the relative abundance of soot in non-monsoon period (25%) was much higher than that in monsoon period (14%), indicating Mt. Qomolangma region received more anthropogenic inuence in non-monsoon than monsoon period. | CONG Zhiyuan KANG Shichang QIN Dahe | 2009 | Journal of Environmental Sciences2009,21,7: | 6 |
| 10 | Elemental composition in surface snow from the ultra-high elevation area of Mt. Qomolangma (Everest)显示文摘A total of 14 surface snow (0―10 cm) samples were collected along the climbing route (6500―8844 m a.s.l.) on the northern slope of Mt. Qomolangma in May, 2005. Analysis of elemental concentrations in these samples showed that there are no clear trends for element variations with elevation due to re- distribution of surface snow by strong winds during spring. In addition, local crustal aerosol inputs also have an influence on elemental composition of surface snow. Comparison between elemental concentration datasets of 2005 and 1997 indicated that data from 2005 were of higher quality. Elemental concentrations (especially for heavy metals) at Mt. Qomolangma are comparable with polar sites, and far lower than large cities. This indicates that anthropogenic activities and heavy metal pollution have little effect on the Mt. Qomolangma atmospheric environment, which can be representative of the background atmospheric environment. | ZHANG QiangGong KANG ShiChang CONG ZhiYuan HOU ShuGui LIU YongQin | 2008 | Chinese Science Bulletin2008,53,2: | 5 |
| 11 | Effectiveness of Integrative Medicine Therapy on Coronary Artery Disease Prognosis: A Real-World Study显示文摘Objective: To evaluate the effectiveness of integrative medicine(IM) on patients with coronary artery disease(CAD) and investigate the prognostic factors of CAD in a real-world setting. Methods: A total of 1,087 hospitalized patients with CAD from four hospitals in Beijing, China were consecutively selected between August 2011 and February 2012. The patients were assigned to two groups based on the treatment: Chinese medicine(CM) plus conventional treatment, i.e., IM therapy(IM group); or conventional treatment alone(CT group). The endpoint was major adverse cardiac events [MACE; including cardiac death, myocardial infarction(MI), and revascularization]. Results: A total of 1,040 patients finished the 2-year follow-up. Of them, 49.4%(514/1,040) received IM therapy. During the 2-year follow-up, the total incidence of MACE was 11.3%. Most of the events involved revascularization(9.3%). Cardiac death/MI occurred in 3.0% of cases. For revascularization, logistic stepwise regression analysis revealed that age 65 years [odds ratio(OR), 2.224], MI(OR, 2.561), diabetes mellitus(OR, 1.650), multi-vessel lesions(OR, 2.554), baseline high sensitivity C-reactive protein level 3 mg/L(OR, 1.678), and moderate or severe anxiety/depression(OR, 1.849) were negative predictors(P<0.05); while anti-platelet agents(OR, 0.422), β-blockers(OR, 0.626), statins(OR, 0.318), and IM therapy(OR, 0.583) were protective predictors(P<0.05). For cardiac death/MI, age 65 years(OR, 6.389) and heart failure(OR, 7.969) were negative predictors(P<0.05), while statin use(OR, 0.323) was a protective predictor(P<0.05) and IM therapy showed a beneficial tendency(OR, 0.587), although the difference was not statistically significant(P=0.218). Conclusion: In a real-world setting, for patients with CAD, IM therapy was associated with a decreased incidence of revascularization and showed a potential benefit in reducing the incidence of cardiac death or MI. | ZHAO Kang TIAN Jin-fan ZHAO Cong YUAN Fei GAO Zhu-ye LI Li-zhi LIU Hong-xu WANG Xian GE Chang-jiang LU Shu-zheng | 2019 | Chinese Journal of Integrative Medicine2019,25,1: | 5 |
| 12 | Effective and biocompatible antibacterial surfaces via facile synthesis and surface modification of peptide polymers显示文摘It is an urgent need to tackle drug-resistance microbial infections that are associated with implantable biomedical devices.Host defense peptide-mimicking polymers have been actively explored in recent years to fight against drug-resistant microbes.Our recent report on lithium hexamethyldisilazide-initiated superfast polymerization on amino acid N-carboxyanhydrides enables the quick synthesis of host defense peptide-mimicking peptide polymers.Here we reported a facile and cost-effective thermoplastic polyurethane(TPU)surface modification of peptide polymer(DLL:BLG=90:10)using plasma surface activation and substitution reaction between thiol and bromide groups.The peptide polymer-modified TPU surfaces exhibited board-spectrum antibacterial property as well as effective contact-killing ability in vitro.Furthermore,the peptide polymer-modified TPU surfaces showed excellent biocompatibility,displaying no hemolysis and cytotoxicity.In vivo study using methicillin-resistant Staphylococcus aureus(MRSA)for subcutaneous implantation infectious model showed that peptide polymer-modified TPU surfaces revealed obvious suppression of infection and great histocompatibility,compared to bare TPU surfaces.We further explored the antimicrobial mechanism of the peptide polymer-modified TPU surfaces,which revealed a surface contact-killing mechanism by disrupting the bacterial membrane.These results demonstrated great potential of the peptide-modified TPU surfaces for practical application to combat bacterial infections that are associated with implantable materials and devices. | Ziyi Lu Yueming Wu Zihao Cong Yuxin Qian Xue Wu Ning Shao Zhongqian Qiao Haodong Zhang Yunrui She Kang Chen Hengxue Xiang Bin Sun Qian Yu Yuan Yuan Haodong Lin Meifang Zhu Runhui Liu | 2021 | Bioactive Materials2021,6,12: | 5 |
| 13 | Fog computing for vehicular Ad-hoc networks: paradigms, scenarios, and issues显示文摘Vehicular Ad-hoc networks(VANETs) are kinds of mobile Ad-hoc networks(MANETs), which consist of mobile vehicles with on-board units(OBUs) and roadside units(RSUs). With the rapid development of computation and communication technologies, peripheral or incremental changes in VANETs evolve into a revolution in process. Cloud computing as a solution has been deployed to satisfy vehicles in VANETs which are expected to require resources(such as computing, storage and networking). Recently, with special requirements of mobility, location awareness, and low latency, there has been growing interest in research into the role of fog computing in VANETs. The merging of fog computing with VANETs opens an area of possibilities for applications and services on the edge of the cloud computing. Fog computing deploys highly virtualized computing and communication facilities at the proximity of mobile vehicles in VANET. Mobile vehicles in VANET can also demand services of low-latency and short-distance local connections via fog computing. This paper presents the current state of the research and future perspectives of fog computing in VANETs. Moreover, we discuss the characteristics of fog computing and services based on fog computing platform provided for VANETs. In this paper, some opportunities for challenges and issues are mentioned, related techniques that need to be considered have been discussed in the context of fog computing in VANETs. Finally, we discuss about research directions of potential future work for fog computing in VANETs. Within this article, readers can have a more thorough understanding of fog computing for VANETs and the trends in this domain. | Kang Kai Wang Cong Luo Tao | 2016 | The Journal of China Universities of Posts and Telecommunications2016,23,2: | 4 |
| 14 | Light-absorbing impurities on Keqikaer Glacier in western Tien Shan: concentrations and potential impact on albedo reduction显示文摘Light-absorbing impurities on glaciers are important factors that influence glacial surface albedo and accelerate glacier melt. In this study, the quantity of light-absorbing impurities on Keqikaer Glacier in western Tien Shan, Central Asia, was measured. We found that the average concentrations of black carbon was 2,180 ng/g, with a range from 250 ng/g to more than 10,000 ng/g. The average concentrations of organic carbon and mineral dust were 1,738 ng/g and 194 μg/g, respectively. Based on simulations performed with the Snow Ice Aerosol Radiative model simulations, black carbon and dust are responsible for approximately 64% and 9%, respectively, of the albedo reduction, and are associated with instantaneous radiative forcing of 323.18 W/m2(ranging from 142.16 to 619.25 W/m2) and 24.05 W/m2(ranging from 0.15 to69.77 W/m2), respectively. For different scenarios, the albedo and radiative forcing effect of black carbon is considerably greater than that of dust. The estimated radiative forcing at Keqikaer Glacier is higher than most similar values estimated by previous studies on the Tibetan Plateau, perhaps as a result of black carbon enrichment by melt scavenging. Light-absorbing impurities deposited on Keqikaer Glacier appear to mainly originate from central Asia, Siberia, western China(including the Taklimakan Desert) and parts of South Asia in summer, and from the Middle East and Central Asia in winter.A footprint analysis indicates that a large fraction(>60%) of the black carbon contributions on Keqikaer Glacier comes from anthropogenic sources. These results provide a scientific basis for regional mitigation efforts to reduce black carbon. | YuLan Zhang ShiChang Kang Min Xu Michael Sprenger TanGuang Gao ZhiYuan Cong ChaoLiu Li JunMing Guo ZhiQiang Xu Yang Li Gang Li XiaoFei Li YaJun Liu HaiDong Han | 2017 | Research in Cold and Arid Regions2017,9,2: | 4 |
| 15 | Analysis of interprovincial trade embodied carbon emissions in Beijing-Tianjin-Hebei and surrounding provinces: based on constructed MRIO Model显示文摘The interprovincial trade embodied carbon emissions plays an important role in the national emission reduction target among China's provinces. Furthermore, it will affect the smooth start-up of the national carbon trade market as well as the implementation of targets in 2030 for dealing with the climate change. Based on constructed MRIO model, this paper analyzes the embodied carbon emission trade flows among Beijing, Tianjin, Hebei and surrounding regions such as Shanxi, Shaanxi, and Inner Mongolia. The results indicate that six provinces have formed different patterns of carbon trade balance, where Beijing, Tianjin, and Hebei provinces are in a deficit position, while the other three provinces are in a surplus position.Beijing, Tianjin, and Hebei have transferred part of the carbon emissions to the other three provinces, which shows greater heterogeneity among various provinces and provincial different sectors. On basis of the conclusions, this paper puts forward some suggestions on provincial decomposition, responsibility distribution, and provincial collaborative reduction for national emission reduction targets. | Jianhui Cong Qingyan Liu Jidong Kang Wenju Li Xiaopei Wang Man Li | 2017 | Chinese Journal of Population,Resources and Environment2017,15,1: | 4 |
| 16 | Differences in the Efficiency of Potassium(K) Uptake and Use in Five Apple Rootstock Genotypes显示文摘Plants that grow well while accumulating and transporting less potassium(K) perform better than more-sensitive plants when under deficiency conditions, which makes low-K-input and environmentally friendly agriculture possible. We conducted hydroponics and sand culture experiments to evaluate the efficiency of various apple(Malus domestica Borkh) rootstocks in their K uptake and utilization. Five genotypes were selected which are widely used in China- M. hupehensis Rehd, M. prunifolia Borkh, M. robusta Rehd, M. sieversii Roem, and M. rockii Rehd. Plant heights, root and shoot dry weights, and K concentrations were recorded. These genotypes differed markedly in dry weights, absolute and relative K concentrations, absolute and relative K accumulations, and their K efficiency ratio under deficient K conditions. The last parameter, expressed as relative shoot dry weight, was strongly and positively correlated with the other four parameters in each genotype. Therefore, we suggest that this parameter could serve as an index when selecting K-efficient genotypes. In this study, we have determined that M. sieversiiand M. rockii are K-inefficient genotypes; M. prunifolia is K-efficient genotype; M. hupehensis and M. robusta have moderate levels of potassium efficiency. | CHANG Cong LI Chao LI Cui-ying KANG Xiao-yu ZOU Yang-jun MA Feng-wang | 2014 | Journal of Integrative Agriculture2014,13,9: | 4 |
| 17 | Brown carbon in the cryosphere: Current knowledge and perspective显示文摘Recently, the light-absorbing organic carbon, i.e., brown carbon(Br C), has received an increasing attention, because they could significantly absorb the solar radiation in the range of short wavelengths rather than the purely scattering effect. Br C is ubiquitous in the troposphere. It could undergo long range transport within the atmospheric circulation. After the deposition on the surface of snow or ice in the cryospheric region, as the major light absorbing impurities with black carbon and dust, Br C could reduce the snow albedo and accelerate the glacier melting. In this context, this paper summarized the current knowledge of Br C(in aerosols and snow) in the cryospheric regions including the Arctic, Antarctic,and Alpines. Although some works have been conducted in those region, the current dataset on the optical properties of Br C like Absorption?ngstr€om Exponent(AAE) and Mass Absorption Efficiency(MAE) is still limited, which hampers stimulating an accurate evaluation of its climate effects. Especially in the Himalayas and Tibetan Plateau, where very limited information concerning Br C is available. Considering biomass burning as a dominant source of Br C, a large amount of emissions from biomass burning in South Asia could reach the Himalayas and Tibetan Plateau, where the climate effect of Br C merits more investigation in the future. | WU Guang-Ming CONG Zhi-Yuan KANG Shi-Chang Kimitaka KAWAMURA FU Ping-Qing ZHANG Yu-Lan WAN Xin GAO Shao-Peng LIU Bin | 2016 | Advances in Climate Change Research2016,7,1: | 4 |
| 18 | Multi-Stage Metamorphism of the UHP Pelitic Gneiss from the Southern Altyn Tagh HP/UHP Belt,Western China:Petrological and Geochronological Evidence显示文摘The kyanite-bearing garnet pelitic gneiss from the Jianggalesavi area in southern Altyn Tagh high pressure/ultra-high pressure belt was proved to have been experienced UHP metamorphism (>12 GPa) by the discovery of kyanite and spinel exsolution microstructure in quartz (precursor stishovite). In this study, three stages of retrograded metamorphism (M2-M4) after the UHP metamorphism (Ml) were identified for the UHP pelitic gneiss. The HP granulite-facies stage (M2) was characterized by the mineral assemblage of garnet+kyanite+K?feldspar+nitile+qiiartz±ilinenite, recording the P-T condition of >1.12 GPa and ?850-930℃. The granulite-facies stage (M3) was represented by the mineral assemblage of garnet rim+K-feldspar+sillimanite (SillJ+biotite (Bti)+plagioclase (Pli)+ilmenite+quartz, and confined under P-T conditions of 0.5-0.8 GPa and^770-795℃. The late cooling stage M4 was accompanied by the appearance of fine-grained Pl2, Sill2 and Bt2 in the matrix, and the P-T conditions were 0.4-0.6 GPa and <675℃. A clockvvised P-T path was obtained for the pelitic gneiss in the P-T pseudosection, which showed a deep subduction/collision processes with subsequent exhumation and cooling. Com? bined with the corresponding multistage metamorphic assemblages, the age dating results implied that the zircons from the gneiss have integrated the recording peak metamorphic (Ml,484±3 Ma) and retrograded metamorphic ages (M2 to M3, 450±2 Ma). There was about 32 Ma interval during the first exhumation from the upper mantle depth (>350 km) to the lower crust depth (-40-20 km), resulting in an average exhumation rate of 9.11-9.70 mm/yr. In the southern Altyn Tagh region, the HP and UHP rocks from different areas had identical peak metamorphic ages. Therefore, contemporary UHP and HP rocks with different metamorphic evolutions were recognized coexisting in the same orogenic belt, which can be interpreted by the model of subduction channel.

| 20 | Extension Protocol for the Investigation on Nutrition Status and Clinical Outcome of Patients with Common Cancers in China(INSCOC)Study:2021 update显示文摘Background Malnutrition is common in patients with cancer,and this adversely affects the survival and quality of life of patients.Chinese Society for Nutritional Oncology issued a multi-center,large-scale,long-term follow-up prospective study,the Investigation on Nutrition Status and Clinical Outcome of Patients with Common Cancers in China(INSCOC study)since 2013.This is an extension to the previous 2013-2020 study protocol.This study still sought to:①address the prognostic impact of nutritional factors and quality of life on cancer patient survival;②describe the overall and cancer-specific incidence and/or distribution of malnutrition and different measurements of patient quality of life.Methods and study design This is an observational,multi-centered,hospital-based prospective cohort study.Data collection will be performed at baseline(within 48 hours after patient admission),during the hospital stay and 30 days after hospital admission.Follow-up will be conducted for 1-20 years after enrollment.The primary outcome will be the all-cause mortality/overall survival,and secondary outcomes will be the length of hospital stay and costs of hospitalization.Study factors will include demographic characteristics,tumor characteristics,information about chronic diseases,hematological measurements(e.g.,red blood cell count,total lymphocyte counts,hemoglobin,albumin,prealbumin,creatinine,C-reactive protein,IL-6),anthropometric measurements(e.g.,height,weight,arm circumference,arm muscle circumference,triceps skinfold thickness,and waist circumference),body composition parameters,PG-SGA scores,quality of life(as indicated by the QLQ-C30 questionnaire),muscle mass(as indicated by the calf circumference),muscle strength(as indicated by the handgrip strength),muscle function(as indicated by the six-meter walking speed test)and physical status assessments(as indicated by the Karnofsky Performance Status scores).This clinical study protocol was approved by local Ethics Committees of all the participating hospitals.Written informed consent is required for each subject included.Discussion This multi-center,large-scale,long-term follow up prospective study will help improve the diagnosis of malnutrition in cancer patients and identify the risk factors associated with adverse clinical outcomes.The anticipated results of this study will highlight the need for a truly scientific appraisal of nutrition therapy in Chinese oncology populations,and finally help treat the potentially reversible elements of malnutrition in cancer patients to improve their clinical outcomes in the future. | Hong Xia Xu Chun Hua Song Liang Yu Yin Chang Wang Zhen Ming Fu Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Zhi Kang Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Xiang Hua Wu Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Ya Yin Yu Quan Jun Lyu Hong Qiu Ming Liu Wei Li Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group | 2022 | Journal of Nutritional Oncology2022,7,2: | 3 |
