| 1 | The first offshore natural gas hydrate production test in South China Sea显示文摘Natural gas hydrates (NGH)is one of key future clean energy resources.Its industrialized development will help remit the huge demand of global natural gas,relieve the increasing pressure of the environment, and play a vital role in the green sustainable growth of human societies.Based on nearly two decades' studying on the reservoir characteristics in the South China Sea (SCS)and the knowledge of reservoir system,the China Geological Survey (CGS)conducted the first production test on an optimal target selected in Shenhu area SCS in 2017.Guided by the 'three-phase control'exploitation theory which focused on formation stabilization,technologies such as formation fluid extraction,well drilling and completing, reservoir stimulating,sand controlling,environmental monitoring,monitoring and preventing of secondary formation of hydrates were applied.The test lasted for 60 days from May 10^th when starting to pump, drop pressure and ignite to well killing on July 9^th,with gas production of 3.09×10^5 m^3 in total,which is a world record with the longest continuous duration of gas production and maximal gas yield.This successful test brings a significant breakthrough on safety control of NGH production. | Jin-fa Li Jian-liang Ye Xu-wen Qin Hai-jun Qiu Neng-you Wu Hai-long Lu Wen-wei Xie Jing-an Lu Fei Peng Zhen-qiang Xu Cheng Lu Zeng-gui Kuang Jian-gong Wei Qian-yong Liang Hong-feng Lu Bei-bei Kou | 2018 | China Geology2018,1,1: | 117 |
| 2 | Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection. | Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu | 2020 | Science China(Life Sciences)2020,63,3: | 157 |
| 3 | Inhibition of SARS-CoV-2 (previously 2019-nCoV) infection by a highly potent pan-coronavirus fusion inhibitor targeting its spike protein that harbors a high capacity to mediate membrane fusion显示文摘The recent outbreak of coronavirus disease(COVID-19)caused by SARS-CoV-2 infection in Wuhan,China has posed a serious threat to global public health.To develop specific anti-coronavirus therapeutics and prophylactics,the molecular mechanism that underlies viral infection must first be defined.Therefore,we herein established a SARS-CoV-2 spike(S)protein-mediated cell-cell fusion assay and found that SARS-CoV-2 showed a superior plasma membrane fusion capacity compared to that of SARS-CoV.We solved the X-ray crystal structure of six-helical bundle(6-HB)core of the HR1 and HR2 domains in the SARS-CoV-2 S protein S2 subunit revealing that several mutated amino acid residues in the HR1 domain may be associated with enhanced interactions with the HR2 domain.We previously developed a pan-coronavirus fusion inhibitor,EK1,which targeted the HR!domain and could inhibit infection by divergent human coronaviruses tested,including SARS-CoV and MERS-CoV.Here we generated a series of lipopeptides derived from EK1 and found that EK1C4 was the most potent fusion inhibitor against SARS-CoV-2 S protein-mediated membrane fusion and pseudovirus infection with IC50s of 1.3 and 15.8 nM,about 241-and 149-fold more potent than the original EK1 peptide,respectively.EK1C4 was also highly effective against membrane fusion and infection of other human coronavirus pseudoviruses tested,including SARS-CoV and MERS-CoV,as well as SARSr-CoVs,and potently inhibited the replication of 5 live human coronaviruses examined,including SARS-CoV-2.Intranasal application of EK1C4 before or after challenge with HCoV-OC43 protected mice from infection,suggesting that EK1C4 could be used for prevention and treatment of infection by the currently circulating SARS-CoV-2 and other emerging SARSr-CoVs. | Shuai Xia Meiqin Liu Chao Wang Wei Xu Qiaoshuai Lan Siliang Feng Feifei Qi Linlin Bao Lanying Du Shuwen Liu Chuan Qin Fei Sun Zhengli Shi Yun Zhu Shibo Jiang Lu Lu | 2020 | Cell Research2020,30,4: | 81 |

| 7 | Effects of AT1 receptor antagonist,Iosartan,on rat hepatic fibrosis induced by CCl_4显示文摘AIM To investigate effect of losartan,an AT1receptor antagonist,on hepatic fibrosis induced byCCl;and to determine whether or not AT1receptors are expressed on hepatic stellate cells,METHODS AND RESULTS Fifty male Sprague-Dawley rats,weighing(180±20)g,wererandomized into five groups(control group,modelgroup,and three losartan treated groups),inwhich all rats were given the subcutaneousinjection of 40% CCl4(every 3 days for 6 weeks)except for rats of control group.Rats of losartan-treated groups were treated with losartan(20 mg/kg,10 mg/kg,5 mg/kg,daily gavage),After 6weeks liver tissue and serum samples of all ratswere examined.Serum hyaluronic acid(HA),procollagen typeⅢ(PCⅢ)were detected byradioimmunoassays,van Giesion collagen stainingwas used to evaluate the extracellular matrix of ratswith liver fibrosis.The expression of AT1receptors,transforming growth factor-beta(TGF-β),and alpha-smooth muscle actin(a-SMA)inliver tissue were determined byimmunohistochemical techniques.Compared withmodel group,serum ALT and AST of losartan-treated groups were significantly reduced(t=4.20,P<0.01 and t=4.57,P<0.01).Serum HAand PCⅢalso had significant differences(t=3.53,P<0.01 and t=2.20,P<0.05).Thedegree of fibrosis was improved by losartan and correlated with the expressions of AT1 receptors,TGF-β,and α-SMA in liver tissue.CONCLUSION AT1 receptor antagonist,losartan,could limit the progression of the hepatic fibrosisinduced by CCl4.The mechanism may be related tothe decrease in the expression of AT1 receptorsand TGF-β,ameliorating the injury of hepatocytes;activation of local renin-angiotensin system mightrelate to hepatic fibrosis;and during progressionof fibrosis,activated hepatic stellate cells mightexpress AT1 receptors. | Hong Shan Wei Ding Guo Li Han Ming Lu Yu Tao Zhan Zhi Rong Wang Xin Huang Jing Zhang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China | 2000 | World Journal of Gastroenterology2000,6,4: | 42 |

| 9 | Estimation of internal nutrient release in large shallow Lake Taihu, China显示文摘Based on field investigation of wave, sediment suspension and the changes in nutrient concentration of the water column in Lake Taihu, China, we proposed two release models to quantify nutrient release under static and dynamic conditions, respectively. Under static conditions, nutrient release from sediments to the overlying water mainly depends on chemical diffusion induced by concentration gradient, in which the nutrient release is controlled by the temperature, dissolved oxygen concentration in the sediment-water interface, oxidation-reduction potential and the concentration difference between porewater and overlying water. Under dynamic condition (or disturbed condition),both dissolved and particulate nutrients in sediments are released into the water column because of wind-induced sediment suspension. The amount of nutrient release under dynamic conditions is larger than that under the static condition. The release of dissolved nutrients, however, does not increase because the wind induced turbulence made oxidation of metallic elements such as Fe (ferric iron), Mn which are capable of precipitating soluble reactive phosphate (SRP). Under dynamic conditions, therefore, the release of total phosphorus (TP) increases dramatically but the release of SRP is close to those under static conditions. In sediments of Lake Taihu, high Fe content leads to a high ratio of Fe to P contents in sediments (Fe:P ratio). Under dynamic conditions, therefore, nutrient release is controlled by the intensity of disturbance, sediment consolidation and nutrient content in sediments.As for dissolved nutrients, especially SRP, the release is also controlled by the intensity of dynamic re-oxidation, Fe content in sediments and nutrient concentration gradient between porewater and overlying water. Based on these two release modes, the release flux in Lake Taihu has been estimated. In the static condition (i.e. laboratory experimental condition), total release of NH4+-N for whole lake is ca. 10,000 ton/a, and PO43--P is ca. 900 ton/a. In the dynamic condition, nutrient release following sediment suspension was estimated according to three different intensities of wind forcing which were defined as 'calm' (wind speed is less than 2 m/s), 'gentle' (wind speed is greater than 2 m/s and less than 6 m/s) and 'gust' (wind speed is greater than 6 m/s). The release rate in the condition of 'calm' was estimated in terms of the nutrient release in the laboratory experimental static condition; whereas the release rate in conditions of 'gentle' and 'gust' was estimated in terms of measurement during sediment resuspension conducted in flume experiments. With the observation of wind velocity and frequency in 2001, each type of wind forcing took the frequency of 12%, 82% and 6% for 'calm', 'gentle' and 'gust', respectively. The yearly release of nitrogen was 81,000 ton and phosphorus was 21,000 ton, which is about 2-6 folds of annual external loading, respectively. | QIN Boqiang, ZHU Guangwei, ZHANG Lu, LUO Liancong, GAO Guang & GU Binhe Nanjing Institute of Geography & Limnology, Chinese Academy of Sciences, Nanjing 210008, China Everglades Department, South Florida Water Management District, 3301 Gun Club Road, West Palm Beach, FL 33406, USA | 2006 | Science China Earth Sciences2006,49,z1: | 37 |
| 10 | Mechanism and control of lake eutrophication显示文摘A review about lake naturally eutrophi- cating, the internal loading of nutrients from lake sediment as well as the mechanism of algal blooms and the control practices was made, especially the eutrophication problem of shallow lakes since sev- enty percent of fresh water lakes in China are shallow lakes. It was found that shallow lakes are apt toward eutrophication than deep lakes. Without any influ- ences of human activity, shallow lakes in the middle and lower reaches of Yangtze River are still easily eutrophicated, which may be owing to the effects of flood in this area. In shallow lakes, sediments are frequently disturbed by wind-wave and resuspended, which result in huge nutrients release to overlying water. This may be the major reason for higher in- ternal loading of nutrients in shallow lakes than in deep lakes. Algal bloom is an extreme response of lake ecosystem to the eutrophication. Appearance of algal blooms is related to physical condition of lakes, such as underwater radiation (or transparency), temperature, and hydrodynamic conditions, or related to geochemical conditions of lakes, like concentra- tions of nutrients and ratio of nitrogen to phosphorus, as well as the physiological advantage of cyanobac- teria such as vacuole for moving towards the radiant energy-rich zone and the mycosporine-like amino acids (MAAs) for resisting the harm of ultraviolet ra- diation. In shallow lakes, these advantages of cyanobacteria are favorable in the competition than in deep lakes. Also being the shallowness, it is more difficult to reduce nutrient loading and to control algae blooms in shallow lakes. For the control of eutrophi- cation, people should follow the sequence from pollution sources control, ecological restoration tocatchment management. To control the internal nu- trient release, physical, chemical, biological tech- niques, and even bionic techniques could be selected. The idea of ecological restoration for a eutrophic lake is to shift the ecosystem from phytoplankton-domi- nant state to macrophyte-dominant state. To realize the shift of ecosystem state, environmental condition improvement is the fundamental work. Nowadays, we should do more work on environmental condition improvement than on planting of macrophytes since we are lack of the knowledge about the relationship between macrophyte and lake ecosystem. Empha- sizing the macrophyte planting, therefore, has blind- ness at present. Because all lakes have different characteristics of environment and ecosystem, ap- plicable lake harness techniques should be selected based on the distinct ecosystem types and environ- mental problems. | QIN Boqiang YANG Liuyan CHEN Feizhou ZHU Guangwei ZHANG Lu CHEN Yiyu | 2006 | Chinese Science Bulletin2006,51,19: | 38 |
| 11 | Metastatic human hepatocellular carcinoma models in nude mice and cell line with metastatic potential显示文摘Metastatic human HCC model is needed for the studies on mechanism and intervention of metastatic recurrence. By using orthotopic implantation of histologically intact tissues of 30 surgical specimens, a patient like metastatic model of human HCC in nude mice (LCI-D20)and a Iow metastatic model of human HCC in nude mice LCI-D35 ) have been established. All mice with transplanted LCI-D20 tumors exhibited extremely high metastatic ability including spontaneous metastasis to liver, lungs, lymph nodes and peritoneal seeding.Remarkable difference was also found in expression of some of the invasiveness related genes and growth factors between the LCI-D20 and LCI-D35 tumors. PAI-Iincreased gradually following tumor progression in LCID20 model, and correlated with tumor size and AFP level,Phasic expression of tissue intercellular adhesion molecule-I in this model was also observed. Using corneal micropocket model, it was demonstrated that the vascular response induced by LCI-D20 tumor was stronger than that induced by LCI-D35 tumor. Similar report on metastatic human HCC model in nude mice and human HCC cell line with metastatic potential was rarely found in the literature. This LCI-D20 model has been widely used for the studies on intervention of metastasis, including antiangiogenesis, antisense approach, metalloproteinase inhibitor, differentiation inducer, etc. It is concluded that the establishment of metastatic human HCC model in nude mice and human HCC cell line with metastatic potential will provide important models for the in vivo and in vitro study of HCC invasiveness, angiogenesis as well as intervention of HCC recurrence. | Zhao-You Tang Fan-Xian Sun Jian Tian Sheng-Long Ye Yin-Kun Liu Kang-Da Liu Qiong Xue Jie Chen Jing-Lin Xia Lun-Xiu Qin Hui-Chuan Sun Lu Wang Jian Zhou Yan Li Zeng-Chen Ma Xin-Da Zhou Zhi-Quan Wu Zhi-Ying Lin Bing-Hui Yang Liver Cancer Institute of Fudan University and Zhongshan Hospital,Shanghai 200032,China | 2001 | World Journal of Gastroenterology2001,7,5: | 34 |

| 13 | Long-Term Effect of Fertilizer and Rice Straw on Mineral Composition and Potassium Adsorption in a Reddish Paddy Soil显示文摘Increasing K+ adsorption can be an effective alternative in building an available K pool in soils to optimize crop recovery and minimize losses into the environment. We hypothesized that long-term fertilization might change K+ adsorption because of changes in the chemical and mineralogical properties of a rice (Oryza sativa L.). The aims of this study were (i) to determine clay minerals in paddy soil clay size fractions using X-ray diffraction methods and a numerical diagram-decomposition method; (ii) to measure K+ adsorption isotherms before and after H 2 O 2 oxidation of organic matter, and (iii) to investigate whether K+ adsorption is correlated with changes in soil chemical and mineral properties. The 30-yr long-term fertilization treatments caused little change in soil organic C (SOC) but a large variation in soil mineral composition. The whole-clay fraction (<5 μm) corresponded more to the fertilization treatment than the fine-clay fraction (<1 μm) in terms of percentage of illite peak area. The total percentage of vermiculite-chlorite peak area was significantly negatively correlated with the total percentage of illite peak area in the <5 μm soil particles (R=-0.946, P<0.0006). Different fertilization treatments gave significantly different results in K+ adsorption. The SOC oxidation test showed positive effects of SOC on K+ adsorption at lower K+ concentration ( 120 mg L-1) and negative effects at higher K+ concentration (240 mg L-1). The K+ adsorption by soil clay minerals after SOC oxidization accounted for 60-158% of that by unoxidized soils, suggesting a more important role of soil minerals than SOC on K+ adsorption. The K+ adsorption potential was significantly correlated to the amount of poorly crystallized illite present (R=0.879, P=0.012). The availability of adsorbed K+ for plant growth needs further study. | LIAO Yu-lin ZHENG Sheng-xian NIE Jun XIE Jian LU Yan-hong QIN Xiao-bo | 2013 | Journal of Integrative Agriculture2013,12,4: | 30 |
| 14 | The regulatory role of AT 1 receptor on activated HSCs in hepat,c fibrogenesis,effects of RAS inhibitors on hepatic fibrosis induced by CCl_4显示文摘AIM To assess the effect of ACE inhibitor andAng Ⅱ type Ⅰ(AT1)receptor antagonist inpreventing hepatic fibrosis caused by CCl4administration in rats;to investigate whether ornot there are expression of AT 1 receptors onhepatic stellate cells;and to observe the effectof Ang Ⅱ on proliferation and ECM synthesis ofcultured HSCs.METHODS Studies were conducted in maleSprague-Dawley rats.Except for thehepatofibrotic model group and the controlgroup,in three treated groups,either enalapril(5 mg/kg),or Iosartan(10 mg/kg),or enalapril+Iosartan were given to the fibrotic rats bydaily gavage,and saline vehicle was given tomodel and normal control rats.After 6 weeks,liver fibrosis was assessed directly by hepaticmorphometric analysis,which has beenconsidered the gold standard for thequantification of fibrosis.The expressions of AT1 receptors and(α-mooth muscle actin,α-SMA)in liver tissue or isolated hepatic stellate cells(HSCs)were detected by immunohistochemicaltechniques.The effect of Ang Ⅱ on HSCproliferation was determined by MTT method.Effect of Ang Ⅱ on collagen synthesis of HSCswas determined by 3H-proline incorporation.RESULTS Contrasted to the fibrosis in rats ofthe model group,groups of rats treated with either enalapril or Iosartan,or a combination oftwo drugs showed a limited expansion of theinterstitium(4.23±3.70 vs 11.22±4.79,P<0.05),but no difference was observedamong three treated groups(5.38±3.43,4.96±2.96,4.23±2.70,P>0.05).Expression of AT 1receptors was found in fibrotic interstitium offibrotic rats,whereas in normal control rats theywere limited to vasculature only to a very slightdegree.AT 1 receptors were also expressed onactivated HSCs in the culture.At concentrationsfrom 10-9to 10-5mol/L,Ang Ⅱ stimulated HSCproliferation in culture in a dose-dependentmanner.Increasing Ang Ⅱ concentrationsproduced corresponding increases in 3H-prolineincorporation.Differences among groups were significant.CONCLUSION Angiotensin-converting enzyme inhibitors and AT I blocker may slow the progression of hepatic fibrosis; activated HSCs express AT 1 receptors, and Ang Ⅱ can stimulate the proliferation and collagen synthesis of HSCs in a dose-dependent manner; and activation of RAS may be related to hepatic fibrogenesis induced by CCI4. | Hong Shan Wei Han Ming Lu Ding Guo Li Yu Tao Zhan Zhi Rong Wang Xin Huang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China | 2000 | World Journal of Gastroenterology2000,6,6: | 27 |

| 16 | Th22 cells are associated with hepatocellular carcinoma development and progression显示文摘Objective: IL-22-producing CD4+ T helper cells(Th22 cells) have been identified as major inducers of tissue inflammation and immune responses. Currently, no previous study explored the role of Th22 cells in the pathogenesis of hepatocellular carcinoma(HCC). The study aimed to determine the biological function of Th22 cells and its effector IL-22 in HCC patients.Methods: Forty-five HCC patients and 19 healthy controls were recruited and their peripheral blood was collected. The fresh HCC tissues, adjacent HCC tissues and ten normal liver tissues were also collected. Flow cytometry analysis was used to determine the frequencies of circulating Th22 cells and Th17 cells. Serum IL-22 levels were tested by enzyme-linked immunosorbent assay(ELISA). Immunohistochemical staining and real-time polymerase chain reaction(PCR) were used to detect IL-22 protein and mRNA in tissues specimens, respectively.Results: Circulating Th22 cells, Th17 cells and serum IL-22 levels were significantly elevated in HCC patients compared with those of healthy controls(P<0.001). Th22 cells were showed to be positively correlated with IL-22 in HCC patients(P<0.05), but not in healthy controls. No significant differences were found in HCC patients with HBeAg positivity or negativity in term of Th22 cells and serum IL-22 levels. The expression of IL-22 protein and mRNA was highest in HCC tissues, followed by adjacent HCC tissues and normal liver tissues. Furthermore, Th22 cells, serum IL-22 levels and IL-22 mRNA were elevated at stage III-IV compared with stage I-II of HCC(P<0.05).Conclusions: Elevation of circulating Th22 cells and IL-22 may be implicated in the pathogenesis of HCC, and potentially be cellular targets for therapeutic intervention. | Shanyu Qin Shijia Ma Xiaoli Huang Donghong Lu You Zhou Haixing Jiang | 2014 | Chinese Journal of Cancer Research2014,26,2: | 25 |
| 17 | Rapeseed research and production in China显示文摘Rapeseed(Brassica napus L.) is the largest oilseed crop in China and accounts for about 20% of world production.For the last 10 years,the production,planting area,and yield of rapeseed have been stable,with improvement of seed quality and especially seed oil content.China is among the leading countries in rapeseed genomic research internationally,having jointly with other countries accomplished the whole genome sequencing of rapeseed and its two parental species,Brassica oleracea and Brassica rapa.Progress on functional genomics including the identification of QTL governing important agronomic traits such as yield,seed oil content,fertility regulation,disease and insect resistance,abiotic stress,nutrition use efficiency,and pod shattering resistance has been achieved.As a consequence,molecular markers have been developed and used in breeding programs.During 2005–2014,215 rapeseed varieties were registered nationally,including 210 winter-and 5 spring-type varieties.Mechanization across the whole process of rapeseed production was investigated and operating instructions for all relevant techniques were published.Modern techniques for rapeseed field management such as high-density planting,controlled-release fertilizer,and biocontrol of disease and pests combined with precision tools such as drones have been developed and are being adopted in China.With the application of advanced breeding and production technologies,in the near future,the oil yield and quality of rapeseed varieties will be greatly increased,and more varieties with desirable traits,especially early maturation,high yield,high resistance to biotic and abiotic stress,and suitability for mechanized harvesting will be developed.Application of modern technologies on the mechanized management of rapeseed will greatly increase grower profit. | Qiong Hu Wei Hua Yan Yin Xuekun Zhang Lijiang Liu Jiaqin Shi Yongguo Zhao Lu Qin Chang Chen Hanzhong Wang | 2017 | The Crop Journal2017,5,2: | 25 |
| 18 | Beta-Glucosidase Activity in Paddy Soils of the Taihu Lake Region, China显示文摘The profile distribution of β-gulcosidase activity in twelve typical paddy soil profiles with high productivity in the Taihu Lake region of China were investigated. Activities of β-gulcosidase in the plow layers were in the range of 52.68-137.02 μg PNP g-1 soil h-1 with a mean of 89.22 μg PNP g-1 soil h-1. However, most plow layers ranged from 70 to 110 μg PNP g-1 soil h-1. The profile distribution of β-gulcosidase activity in the 12 soil profiles decreased rapidly with soil depth, with activity at the 60 cm depth only about 10% of that in the surface layers (0-15 cm or 0-20 cm). In these soil profiles, β-gulcosidase activity was significantly positively correlated with soil organic carbon and arylsulphatase activity. Meanwhile, a significantly negative correlation was shown between β-gulcosidase activity and soil pH. | WANG Xiao-Chang LU Qin | 2006 | Pedosphere2006,16,1: | 24 |

| 20 | Ten cities cross-sectional questionnaire survey of children asthma and other allergies in China显示文摘Asthma,rhinitis and eczema(allergic or non-allergic)have increased throughout the world during the last decades,especially among children.Changes in the indoor environment are suspected to be important causes.China has experienced a dramatic change in indoor environmental exposures during the past two decades.However,such changes and their associations with children’s asthma and other health aspects have not been thoroughly studied.China,Children,Homes,Health(CCHH),Phase I,was a cross-sectional questionnaire survey of 48219 children 1–8 years old in 10 Chinese cities during 2010–2012.The questionnaire includes the International Study of Asthma and Allergies in Childhood(ISAAC)core health questions and additional questions regarding housing,life habits and outdoor environment.In health analyses,children aged 3–6 years old were included.The prevalences of doctor diagnosed asthma varied from 1.7%to 9.8%(mean 6.8%),a large increase from 0.91%in 1999 and 1.50%in2000.The prevalence of wheeze,rhinitis and atopic eczema(last 12 months)varied from 13.9%to 23.7%,24.0%to 50.8%and4.8%to 15.8%,respectively.Taiyuan had the lowest prevalences of all illnesses and Shanghai the highest,except for wheezewhere the highest value was for Urumqi.We found(1)no obvious association between disease prevalences and ambient PM10concentrations and(2)higher prevalences of disease in humid climates with hot summers and cold winters,but with no centrally heated buildings.Associations between the diseases and economic status as indexed by Gross Domestic Product(GDP)requires further study. | ZHANG YinPing LI BaiZhan HUANG Chen YANG Xu QIAN Hua DENG QiHong ZHAO ZhuoHui LI AnGui ZHAO JiaNing ZHANG Xin QU Fang HU Yu YANG Qin WANG Juan ZHANG Ming WANG Fang ZHENG XiaoHong LU Chan LIU ZhiJian SUN YueXia MO JinHan ZHAO YiLi LIU Wei WANG TingTing NORBCK Dan BORNEHAG Carl-Gustaf SUNDELL Jan | 2013 | Chinese Science Bulletin2013,58,34: | 22 |
