| 1 | Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control. | Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu | 2021 | Science China(Life Sciences)2021，64，5： | 46 |
| 2 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |
| 3 | Effects of warming and clipping on plant and soil properties of an alpine meadow in the Qinghai-Tibetan Plateau, China显示文摘Climate warming and livestock grazing are known to have great influences on alpine ecosystems like those of the Qinghai-Tibetan Plateau(QTP) in China. However, it is lacking of studies on the effects of warming and grazing on plant and soil properties in these alpine ecosystems. In this study, we reported the related research from manipulative experiment in 2010–2012 in the QTP. The aim of this study was to investigate the individual and combined effects of warming and clipping on plant and soil properties in the alpine meadow ecosystem. Infrared radiators were used to simulate climate warming starting in July 2010, while clipping was performed once in October 2011 to simulate the local livestock grazing. The experiment was designed as a randomized block consisting of five replications and four treatments: control(CK), warming(W), clipping(C) and warming+clipping combination(WC). The plant and soil properties were investigated in the growing season of the alpine meadow in 2012. The results showed that W and WC treatments significantly decreased relative humidity at 20-cm height above ground as well as significantly increases air temperature at the same height, surface temperature, and soil temperature at the depth of 0–30 cm. However, the C treatment did not significantly decrease soil moisture and soil temperature at the depth of 0–60 cm. Relative to CK, vegetation height and species number increased significantly in W and WC treatment, respectively, while vegetation aboveground biomass decreased significantly in C treatment in the early growing season. However, vegetation cover, species diversity, belowground biomass and soil properties at the depth of 0–30 cm did not differ significantly in W, C and WC treatments. Soil moisture increased at the depth of 40–100 cm in W and WC treatments, while belowground biomass, soil activated carbon, organic carbon and total nitrogen increased in the 30–50 cm soil layer in W, C and WC treatments. Although the initial responses of plant and soil properties to experimental warming and clipping were slow and weak, the drought induced by the downward shift of soil moisture in the upper soil layers may induce plant belowground biomass to transfer to the deeper soil layers. This movement would modify the distributions of soil activated carbon, organic carbon and total nitrogen. However, long-term data collection is needed to further explain this interesting phenomenon. | Man Hou XU Fei PENG Quan Gang YOU Jian GUO Xia Fei TIAN Min LIU Xian XUE | 2015 | Journal of Arid Land2015，7，2： | 14 |
| 4 | Celastrol induces ferroptosis in activated HSCs to ameliorate hepatic fibrosis via targeting peroxiredoxins and HO-1显示文摘Ferroptosis is a form of regulated cell death, characterized by excessive membrane lipid peroxidation in an iron-and ROS-dependent manner. Celastrol, a natural bioactive triterpenoid extracted from Tripterygium wilfordii, shows effective anti-fibrotic and anti-inflammatory activities in multiple hepatic diseases. However, the exact molecular mechanisms of action and the direct protein targets of celastrol in the treatment of liver fibrosis remain largely elusive. Here, we discover that celastrol exerts anti-fibrotic effects via promoting the production of reactive oxygen species(ROS) and inducing ferroptosis in activated hepatic stellate cells(HSCs). By using activity-based protein profiling(ABPP) in combination with bio-orthogonal click chemistry reaction and cellular thermal shift assay(CETSA), we show that celastrol directly binds to peroxiredoxins(PRDXs), including PRDX1, PRDX2, PRDX4 and PRDX6,through the active cysteine sites, and inhibits their anti-oxidant activities. Celastrol also targets to heme oxygenase 1(HO-1) and upregulates its expression in activated-HSCs. Knockdown of PRDX1, PRDX2,PRDX4, PRDX6 or HO-1 in HSCs, to varying extent, elevated cellular ROS levels and induced ferroptosis. Taken together, our findings reveal the direct protein targets and molecular mechanisms via which celastrol ameliorates hepatic fibrosis, thus supporting the further development of celastrol as a promising therapeutic agent for liver fibrosis. | Piao Luo Dandan Liu Qian Zhang Fan Yang Yin-Kwan Wong Fei Xia Junzhe Zhang Jiayun Chen Ya Tian Chuanbin Yang Lingyun Dai Han-Ming Shen Jigang Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 14 |
| 5 | Seroepidemiological Investigation of Lyme Disease and Human Granulocytic Anaplasmosis among People Living in Forest Areas of Eight Provinces in China显示文摘Objective Lyme disease and Human granulocytic anaplasmosis are tick‐borne diseases caused by Borrelia burgdorferi and Anaplasma phagocytophilum respectively. We have investigated infection and co-infection of the two diseases in the population of forest areas of eight provinces in China by measuring seroprevalence of antibodies against B. burgdorferi and A. phagocytophilum. Methods Forest areas in 8 provinces were chosen for investigation using whole sampling and questionnaire survey methods. 3 669 serum samples from people in the forest areas were tested for the presence of antibodies by indirect immunofluorescent assay (IFA). Results Seroprevalence against B. burgdorferi was 3% to 15% and against A. phagocytophilum was 2% to 18% in the study sites in the 8 provinces in China. We also found co-infection of B. burgdorferi and A. phagocytophilum in 7 of the 8 provinces (the exception being the Miyun area in Beijing). The seroprevalence for both B. burgdorferi and A. phagocytophilum was significantly higher among people exposed to ticks than among people who were not exposed to ticks. Conclusion We conclude that both pathogens are endemic in the forest areas in the eight provinces, but the prevalence of B. burgdorferi and A. phagocytophilum differs between the provinces. | HAO Qin GENG Zhen HOU Xue Xia TIAN Zhen YANG Xiu Jun JIANG Wei Jia SHI Yan ZHAN Zhi Fei LI Guo Hua YU De Shan WANG Hua Yong XU Jian Guo WAN Kang Lin | 2013 | Biomedical and Environmental Sciences2013，26，3： | 13 |
| 6 | Casticin induces caspase-mediated apoptosis via activation of mitochondrial pathway and upregulation of DR5 in human lung cancer cells显示文摘Objective:To assess if casticin induces caspase-mediated apoptosis via activation of mitochondrial pathway and upregulation of DR5 in human lung cancer ceils.Methods:Human non-small-cell lung carcinoma cell lines H460,AS49 and H157 were cultured in vitro.The cytotoxic activities were determined using MTT assay.The apoptotic cells death was examined by flow cytometry using PI staining and DMA agarose gel electrophoresis.The activities of caspase-3, -8 and -9 were measured via ELISA.Cellular fractionation was determined by flow cytometry to assess release of cytochrome c and the mitochondrial transmembrane potential.Bcl-2/Bcl-XL/ XIAP/Bid/ DR5 and DR4 proteins were analyzed using western blot.Results:The concentrations required for a 50%decrease in cell growth(IC50) ranged from 1.8 to 3.2 Jt M.Casticin induced rapid apoptosis and triggered a series of effects associated with apoptosis by way of mitochondrial pathway,including the depolarization of the mitochondrial membrane,release of cytochrome c from mitochondria,activation of procaspase-9 and -3,and increase of DNA fragments.Moreover, the pan caspase inhibitor zVAD-FMK and the caspase-3 inhibitor zOEVD-FMK suppressed casticin-induced apoptosis.In addition,casticin induced XIAP and Bcl-XL down-regulation, Bax upregulation and Bid clearage.In H157 cell line,casticin increased expression of DRS at protein levels but not affect the expression of DR4.The prelreatmenl with DR5/Fc chimera protein effectively attenuated casticin-induced apoptosis in H157 cells.No correlation was found between cell sensitivity to casticin and that to p53 status,suggesting that casticin induce a p53- independent apoptosis.Conclusions:Our results demonstrate that casticin induces caspase-mediated apoptosis via activation of mitochondrial pathway and upregulation of DRS in human lung cancer cells. | Yuan Zhou Yi Peng Qi-Qi Mao Xia Li Ming-Wu Chen Ting Su Li Tian Nai-Quan Mao Ling-Zhi Long Mei-Fang Quan Fei Liu Su-Fang Zhou Yong-Xiang Zhao | 2013 | Asian Pacific Journal of Tropical Medicine2013，6，5： | 11 |
| 7 | Major advances in studies of the physical geography and living environment of China during the past 70 years and future prospects显示文摘The natural environment provides material essentials for human survival and development. The characteristics,processes, regional differentiation and forcing mechanisms of the elements of the natural environment(e.g. geomorphology,climate, hydrology, soil, etc.) are the main objects of research in physical geography. China has a complex natural environment and huge regional differentiation and therefore it provides outstanding reserach opportunities in physical geography. This review summarizes the most important developments and the main contributions of research in the physical geography and human living environment in China during the past 70 years. The major topics addressed are the uplift of the Tibetan Plateau and the evolution of its cryosphere, the development of fluvial systems, the acidification of the vast arid region of the Asian interior, variations in the monsoon and westerly climate systems on multiple timescales, the development of lakes and wetlands, the watershed system model, soil erosion, past human-environment interactions, biogeography, and physical geographic zonality. After briefly introducing international research developments, we review the history of research in physical geography in China, focusing on the major achievements and major academic debates, and finally we summarize the status of current research and the future prospects. We propose that in the context of the national demand for the construction of an ecological civilization, we should make full use of the research findings of physical geography, and determine the patterns and mechanisms of natural environmental processes in order to continue to promote the continued contribution of physical geography to national development strategies, and to further contribute to the theory of physical geography from a global perspective. | Fahu CHEN Bojie FU Jun XIA Duo WU Shaohong WU Yili ZHANG Hang SUN Yu LIU Xiaomin FANG Boqiang QIN Xin LI Tingjun ZHANG Baoyuan LIU Zhibao DONG Shugui HOU Lide TIAN Baiqing XU Guanghui DONG Jingyun ZHENG Wei YANG Xin WANG Zaijun LI Fei Wang Zhenbo HU Jie WANG Jianbao LIU Jianhui CHEN Wei HUANG Juzhi HOU Qiufang CAI Hao LONG Ming JIANG Yaxian HU Xiaoming FENG Xingguo MO Xiaoyan YANG Dongju ZHANG Xiuhong WANG Yunhe YIN Xiaochen LIU | 2019 | Science China Earth Sciences2019，62，11： | 11 |
| 8 | Analysis on hydrochemical characteristics of groundwater in strongly exploited area in Hutuo River Plain显示文摘The Hutuo River alluvial-proluvial fan is located in North China Plain, and groundwater is the main source of water supply for agriculture and domestic water. Shijiazhuang depression funnels due to the long-term excessive exploitation are the bottleneck of the regional economic development. Analyzing the chemical characteristics of groundwater under the condition of strong human activities, can provide a scientific basis for further study of strong groundwater mining area environmental change. 143 groups of shallow groundwater samples are collected during the period of 2007-2008. In this paper, the hydrochemical characteristics of groundwater in the Hutuo River Plain area are analyzed systematically, using hydrogeochemical theory, combined with statistical methods and hydrochemical methods. Results are shown as follows: HCO_3^- and Ca^(2+) are major anion and cation. The variation coefficients of K^+, Ca^(2+), Mg^(2+) and HCO_3^- between 0.25 and 0.52, which means small and stable relatively. The variation coefficient of are Na^+, NO_3^-, Cl-, SO2-4 were large(0.89-1.01). They are sensitive and vulnerable to environmental change affect. Due to the impact of human activities, from the top to the edge of the alluvial-proluvial fan, the hydrochemical types of groundwater change from single to multiple, followed by HCO_3^-Ca·Mg, HCO_3·SO_4-Ca·Mg, HCO_3·SO_4·Cl-Ca·Mg, HCO_3·Cl-Ca·Mg and other types. | TIAN Xia FEI Yu-hong ZHANG Zhao-ji LI Ya-song DUN Yu GUO Chun-yan | 2017 | Journal of Groundwater Science and Engineering2017，5，2： | 3 |
| 9 | Serum semaphorin 4C as a diagnostic biomarker in breast cancer:A multicenter retrospective study显示文摘Background:To date,there is no approved blood-based biomarker for breast cancer detection.Herein,we aimed to assess semaphorin 4C(SEMA4C),a pivotal protein involved in breast cancer progression,as a serum diagnostic biomarker.Methods:We included 6,213 consecutive inpatients from Tongji Hospital,Qilu Hospital,and Hubei Cancer Hospital.Training cohort and two validation cohorts were introduced for diagnostic exploration and validation.A pan-cancer cohort was used to independently explore the diagnostic potential of SEMA4C among solid tumors.Breast cancer patients who underwent mass excision prior to modified radical mastectomy were also analyzed.We hypothesized that increased pretreatment serum SEMA4C levels,measured using optimized in-house enzymelinked immunosorbent assay kits,could detect breast cancer.The endpoints were diagnostic performance,including area under the receiver operating characteristic curve(AUC),sensitivity,and specificity.Post-surgery pathological diagnosis was the reference standard and breast cancer staging followed the TNM classification.There was no restriction on disease stage for eligibilities.Results:We included 2667 inpatients with breast lesions,2378 patients with other solid tumors,and 1168 healthy participants.Specifically,118 patients with breast cancer were diagnosed with stage 0(5.71%),620 with stage I(30.00%),966 with stage II(46.73%),217 with stage III(10.50%),and 8 with stage IV(0.39%).Patients with breast cancer had significantly higher serum SEMA4C levels than benign breast tumor patients and normal controls(P<0.001).Elevated serum SEMA4C levels had AUC of 0.920(95%confidence interval[CI]:0.900–0.941)and 0.932(95%CI:0.911–0.953)for breast cancer detection in the two validation cohorts.The AUCs for detecting early-stage breast cancer(n=366)and ductal carcinoma in situ(n=85)were 0.931(95%CI:0.916–0.946)and 0.879(95%CI:0.832–0.925),respectively.Serum SEMA4C levels significantly decreased after surgery,and the reduction was more striking after modified radical mastectomy,compared with mass excision(P<0.001).The positive rate of enhanced serum SEMA4C levels was 84.77%for breast cancer and below 20.75%for the other 14 solid tumors.Conclusions:Serum SEMA4C demonstrated promising potential as a candidate biomarker for breast cancer diagnosis.However,validation in prospective settings and by other study groups is warranted. | Ya Wang Long Qiao Jie Yang Xiong Li Yaqi Duan Jiahao Liu Shaoqi Chen Huayi Li Dan Liu Tian Fang Jingjing Ma Xiaoting Li Fei Ye Junxiang Wan Juncheng Wei Qin Xu Ensong Guo Ping Jin Mingfu Wu Lin Zhang Yun Xia Yaqun Wu Jun Shao Yaojun Feng Qing Zhang Zongyuan Yang Gang Chen Qinghua Zhang Xingrui Li Shixuan Wang Junbo Hu Xiaoyun Wang Mona P.Tan Kazuaki Takabe Beihua Kong Qifeng Yang Ding Ma Qinglei Gao | 2021 | Cancer Communications2021，41，12： | 3 |
| 10 | Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China. | HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li | 2014 | Biomedical and Environmental Sciences2014，27，5： | 3 |
| 11 | Background Characteristics of Atmospheric CO2 and the Potential Source Regions in the Pearl River Delta Region of China显示文摘Mole fractions of atmospheric CO2(XCO2)have been continuously measured from October 2014 to March 2016 at the Guangzhou Panyu Atmospheric Composition Site(23.00°N,113.21°E;140 m MSL)in the Pearl River Delta(PRD)region using a cavity ring-down spectrometer.Approximately 66.63%,19.28%,and 14.09%of the observed values were filtered as background,pollutant source,and sink due to biospheric uptake,respectively,by applying a robust local regression procedure.Their corresponding mean values were 424.12±10.12 ppm(×10-6 mol mol-1),447.83±13.63 ppm,and 408.83±7.75 ppm.The background XCO2 levels were highest in spring and winter,moderate in autumn,and lowest in summer.The diurnal XCO2 was at a minimum from 1400-1600 LST(Local Standard Time)and a maximum at 0500 LST the next day.The increase of XCO2 in spring and summer was mainly associated with polluted air masses from south coastal Vietnam,the South China Sea,and the southeast Pearl River Estuary.With the exception of summer,airflow primarily from marine regions southeast of Taiwan that passed over the Pearl River Estuary had a greater impact on XCO2,suggesting an important potential source region. | Boru MAI Xuejiao DENG Fang ZHANG Hao HE Tian LUAN Fei LI Xia LIU | 2020 | Advances in Atmospheric Sciences2020，37，6： | 2 |

| 16 | Liver resection versus liver transplantation for hepatocellular carcinoma within the Milan criteria based on estimated microvascular invasion risks显示文摘Background:Preoperative prediction of microvascular invasion(MVI)in hepatocellular carcinoma(HCC)may optimize individualized treatment decision-making.This study aimed to investigate the prognostic differences between HCC patients undergoing liver resection(LR)and liver transplantation(LT)based on predicted MVI risks.Methods:We analysed 905 patients who underwent LR,including 524 who underwent anatomical resection(AR)and 117 who underwent LT for HCC within the Milan criteria using propensity score matching.A nomogram model was used to predict preoperative MVI risk.Results:The concordance indices of the nomogram for predicting MVI were 0.809 and 0.838 in patients undergoing LR and LT,respectively.Based on an optimal cut-off value of 200 points,the nomogram defined patients as high-or low-risk MVI groups.LT resulted in a lower 5-year recurrence rate and higher 5-year overall survival(OS)rate than LR among the high-risk patients(23.6%vs 73.2%,P<0.001;87.8%vs 48.1%,P<0.001)and low-risk patients(19.0%vs 45.7%,P<0.001;86.5%vs 70.0%,P=0.002).The hazard ratios(HRs)of LT vs LR for recurrence and OS were 0.18(95%confidence interval[CI],0.09–0.37)and 0.12(95%CI,0.04–0.37)among the high-risk patients and 0.37(95%CI,0.21–0.66)and 0.36(95%CI,0.17–0.78)among the low-risk patients.LT also provided a lower 5-year recurrence rate and higher 5-year OS rate than AR among the high-risk patients(24.8%vs 63.5%,P=0.001;86.7%vs 65.7%,P=0.004),with HRs of LT vs AR for recurrence and OS being 0.24(95%CI,0.11–0.53)and 0.17(95%CI,0.06–0.52),respectively.The 5-year recurrence and OS rates between patients undergoing LT and AR were not significantly different in the low-risk patients(19.4%vs 28.3%,P=0.129;85.7%vs 77.8%,P=0.161).Conclusions:LT was superior to LR for patients with HCC within the Milan criteria with a predicted high or low risk of MVI.No significant differences in prognosis were found between LT and AR in patients with a low risk of MVI. | Pinghua Yang Fei Teng Shilei Bai Yong Xia Zhihao Xie Zhangjun Cheng Jun Li Zhengqing Lei Kui Wang Baohua Zhang Tian Yang Xuying Wan Hao Yin Hao Shen Timothy M Pawlik Wan Yee Lau Zhiren Fu Feng Shen | 2023 | Gastroenterology Report2023，11，1： | 1 |
| 17 | Record Arctic Ozone Loss in Spring 2020 is Likely Caused by North Pacific Warm Sea Surface Temperature Anomalies显示文摘Record ozone loss was observed in the Arctic stratosphere in spring 2020.This study aims to determine what caused the extreme Arctic ozone loss.Observations and simulation results are examined in order to show that the extreme Arctic ozone loss was likely caused by record-high sea surface temperatures(SSTs)in the North Pacific.It is found that the record Arctic ozone loss was associated with the extremely cold and persistent stratospheric polar vortex over February-April,and the extremely cold vortex was a result of anomalously weak planetary wave activity.Further analysis reveals that the weak wave activity can be traced to anomalously warm SSTs in the North Pacific.Both observations and simulations show that warm SST anomalies in the North Pacific could have caused the weakening of wavenumber-1 wave activity,colder Arctic vortex,and lower Arctic ozone.These results suggest that for the present-day level of ozone-depleting substances,severe Arctic ozone loss could form again,as long as certain dynamic conditions are satisfied. | Yan XIA Yongyun HU Jiankai ZHANG Fei XIE Wenshou TIAN | 2021 | Advances in Atmospheric Sciences2021，38，10： | 1 |
| 18 | Quality evaluation of groundwater in the North China Plain显示文摘This paper presents a method combining single-indicator comprehensive evaluation and influence factor identification to measure groundwater quality. This method not only reflects groundwater quality classification with clear physical significance, but also divides the possibilities of man-made pollution in regional groundwater. The paper selects 6 063 representative groundwater wells in the North China Plain to evaluate 49 groundwater inorganic and organic index and comes to a conclusion: Controlled by geological environment and hydrogeological conditions, the groundwater quality in the North China Plain deteriorates from the bottom of maintain to coastal area, with Class I to III groundwater decreasing from 49% to 3.9% while Class V groundwater increasing from 21% to 86.9%; the quality of deep groundwater is better than that of shallow groundwater; the contribution rate of manganese, total hardness, total dissolved solids and iodide in shallow groundwater to over-III type water exceeds 50%; the contribution rate of nitrite in pollution index reaches 20%; while heavy metal and organic indexes have limited impact on regional groundwater quality. The North China Plain is an important economic area in China. Over decades, it has witnessed intense human activities, and water resource quantity demanded has been far greater than quantity supplied. Due to scarce surface water resource, groundwater becomes the pillar supporting regional economic development. This has led to increasing groundwater exploitation and development. According to statistics, the exploitation degree of shallow groundwater reaches 105% in the North China Plain and 118% in the Hebei Plain; the exploitation degree of deep groundwater reaches 143% in the North China Plain and 163% in the Hebei Plain. The serious over-exploitation of groundwater brings various geological environmental problems, with the worsening of groundwater quality being a typical one. Besides impact brought by human activities, the poor quality of natural water in the North China Plain is also an important factor. Therefore, to understand the current regional groundwater quality situation and to master influence factors and influence degree can provide reliable scientific protection for regional economic development. | FEI Yu-hong ZHANG Zhao-ji LI Ya-song GUO Chun-yan TIAN Xia | 2015 | Journal of Groundwater Science and Engineering2015，3，4： | 1 |
| 19 | Association between duration of return of spontaneous circulation and outcomes after out-of-hospital cardiac arrest显示文摘Background:Return of spontaneous circulation(ROSC)is a core outcome element of cardiopulmonary resuscitation(CPR);however,the definition or criterion of ROSC is disputed and varies in resuscitation for out-of-hospital cardiac arrest(OHCA).Methods:This was a retrospective study of 126 patients with OHCA who achieved ROSC between January and December 2020.The probability of survival after OHCA related to CPR and ROSC duration was analyzed using the probability density function and empirical cumulative density functions.Results:There were no significant differences between ROSC sustained until emergency department arrival and that sustained for at least 20 minutes in terms of the 24-hour survival rate(31.3%[31/99]vs.35.7%[10/30];P=0.84),30-day survival rate(23.2%[23/99]vs.25.0%[7/30];P=0.99),or survival at 30 days with cerebral performance category(CPC)1 and 2(18.2%[18/99]vs.10.7%[3/30];P=0.44).The Kolmogorov-Smirnov test values from the empirical cumulative density functions with ROSC sustained until hospital arrival and that sustained for at least 20 minutes were 0.44,0.20,and 0.24 for CPC 1 or 2,CPC 3 or 4,and CPC 5,respectively.Conclusion:Return of spontaneous circulation is a core outcome element of CPR.It should be defined as sustained for at least 20 minutes or until arrival at the emergency department and as a basic standard for evaluating resuscitation success after OHCA. | Huixin Lian Andong Xia Xinyan Qin Sijia Tian Xuqin Kang Luxi Zhang Shengmei Niu Fei Qin Jinjun Zhang | 2022 | Emergency and Critical Care Medicine2022，2，4： | 1 |
| 20 | Refractive outcomes and optical quality of PRESBYOND laser-blended vision for presbyopia correction显示文摘AIM: To investigate the one-year refractive outcomes and optical quality following PRESBYOND laser-blended vision(LBV).METHODS: This retrospective study included 20 patients who underwent PRESBYOND treatment between Jan 2019 and Aug 2020. The patients were asked to attend a followup outpatient visit one year after surgery. Distance and near visual acuity as well as subjective refraction were examined. Optical quality was assessed using wavefront-supported custom ablation. A questionnaire evaluating optical quality and satisfaction was completed at the last visit.RESULTS: The average patient age was 48.1±7.4 y(range, 41 to 58 y). The mean preoperative spherical equivalent was-7.59±2.39D. At the one-year follow-up, two eyes(both dominant eyes) lost one line of corrected distance visual acuity(CDVA), while the remaining eyes(38/40) maintained or gained lines of CDVA. The average binocular uncorrected distance visual acuity improved from 0.15±0.03 to 0.90±0.26(decimal vision;P<0.001). The average binocular uncorrected near visual acuity increased from 0.34±0.28 to 0.97±0.07(P<0.001). The spherical aberration was 0.04±0.06 μm in the nondominant eye and 0.09±0.09 μm in the dominant eye(P=0.02). All patients were satisfied with or accepted the outcomes of the surgery. The primary complaints were related to disturbances in night vision and relatively inferior near vision.CONCLUSION: Over the one-year observation period, PRESBYOND is a safe and effective option for presbyopia correction. The optical quality and near vision deserve further investigation. | Dan Fu Aruma Aruma Ye Xu Tian Han Fei Xia Xing-Tao Zhou | 2022 | International Journal of Ophthalmology(English edition)2022，15，10： | 1 |
