Polychlorinated naphthalenes(PCNs)are detrimental to human health and the environment.With the commercial production of PCNs banned,unintentional releases have emerged as a significant environmental source.However,relevant information is still scarce.In this study,provincial emissions for eight PCNs homologues from 37 sources in the Chinese mainland during the period of 1960-2019 were estimated based on a source-specific and time-varying emission factor database.The results showed that the total PCNs emissions in 2019 reached 757.0 kg with Hebei ranked at the top among all the provinces and iron&steel industry as the biggest source.Low-chlorinated PCNs comprised 90%of emissions by mass,while highly chlorinated PCNs dominated in terms of toxicity,highlighting divergent priorities for mitigating emissions and safeguarding human health.The emissions showed an overall upward trend from 1960 to 2019 driven by emission increase from iron&steel industry in terms of source,and from North China and East China in terms of geographic area.Per-capita emissions followed an inverted U-shaped environmental Kuznets curvewhile emission intensities decreased with increasing per-capita Gross Domestic Product(GDP)following a nearly linear pattern when log-transformed. 展开更多

Background Access to primary healthcare(PHC)services is a critical determinant of population health outcomes and a key indicator of health system performance.However,comprehensive methods for batch assessment of PHC accessibility and the associated economic burden are relatively scarce.This gap is particularly evident in developing countries,where accessibility challenges are often more pronounced.Methods We developed an integrated assessment methodology for the large-scale calculation of travel costs to access PHC services.This methodology combines high-resolution friction surface mapping,the construction of a comprehensive PHC facility spatial dataset,and the application of least-cost path algorithms.The batch processing capability of the methodology ensures efficient computation while maintaining high spatial resolution,enabling a detailed evaluation of PHC accessibility and its economic burden across diverse geographical contexts.Results Our analysis revealed that 88.70%of Chinese mainland's population could access PHC facilities within an hour,indicating relatively good overall accessibility to primary healthcare services.However,significant regional disparities in accessibility and associated economic burdens were observed.While urban areas,particularly in eastern and coastal regions,generally exhibit high levels of accessibility,rural and remote areas,especially in the western and northwestern regions,face substantial challenges in reaching PHC facilities.The total economic burden associated with travel to PHC facilities in Chinese mainland is estimated at approximately 38.29 billion CNY annually.The southern,northern,and northwestern regions accounted for 62.91%,21.72%,and 14.94%of the total burden respectively,with northwestern provinces facing a disproportionately high economic burden relative to their GDP.Conclusions Our methodology supports future large-scale,high-resolution accessibility analyses that can guide interventions aimed at addressing healthcare disparities and improving equity.The empirical application of this methodology in Chinese mainland revealed significant disparities in PHC access across the country and quantified the substantial economic costs associated with these disparities. 展开更多

This study focuses on resolving moderate amounts of crustal motion at the continental scale based on a large volume of global positioning system(GPS)data during 1998e2014.A state-of-the-art GPS processing strategy was used to resolve position time series and velocities from carrier beat phases for all available data.Position time series were closely analyzed to estimate linear constant,coseismic displacements,postseismic motions,and other parameters.We present coseismic offsets inferred from the GPS data for the 2010 Yushu and 2014 Yutian earthquakes,and also illustrate transient postseismic motions following the 2001 Kokoxili,2008 Wenchuan,and 2011 Tohoku-Oki earthquakes.Since not all GPS position time series dominated by postseismic motions can be modeled and corrected reasonably,we present contemporary horizontal velocities from 2009 to 2014 for campaign stations and from 1998 to 2014 for continuous stations,irrespective of postseismic deformations.Our study concludes that we need to accumulate observations over a greater duration and apply accurate postseismic modeling to correct for transient displacement in order to resolve reasonable interseismic velocity. 展开更多

Introduction Over 300000 people in China die each year of hepatocellular carcinoma(HCC),which accounts for approximately half of HCCrelated deaths worldwide.Liver transplantation(LT)is generally recognized as one of the most effective therapeutic approaches for end-stage liver diseases.Since the beginning of the second LT boom in the 1990s,LT in China has been developed rapidly with professional and large-scale trends,and it is approaching or has reached the level of developed countries in terms of quantity and quality.According to the China Liver Transplant Registry,the number of transplants for HCC accounted for 36.8%of the total number of LT cases during the past 5 years in the mainland of China.In order to develop an effective,safe and standardized protocol to guide the national LT practice,the clinical guidelines of LT for HCC was launched in 2014 by multidisciplinary experts from Chinese Society of Organ Transplantation,Chinese Medical Association and Chinese Association of Organ Transplantation,Chinese Medical Doctor Association.Recently,there have been new clinical and scientific advances in the field of LT and to keep abreast of these achievements,the original clinical practice guidelines need to be updated. 展开更多

Electric power consumption(EPC)is one of the basic indices for evaluating electric power use.Obtaining timely and accurate data on the spatiotemporal dynamics of EPC is crucial for understanding and practical deployment of electric power resources.In this study,an EPC model was developed using stable nighttime lights time-series data from the Defense Meteorological Satellite Program Operational Linescan System(DMSP/OLS).The model was used to reconstruct the spatial patterns of EPC in Chinese Mainland at the county level from 1995 to 2008.In addition,the spatiotemporal dynamics of EPC were analyzed,and the fol-lowing conclusions were drawn.(1)The EPC model reliably represented the spatiotemporal dynamics of EPC in Chinese Mainland with approximately 70%accuracy.(2)The EPC in most regions of Chinese Mainland was at low to moderate levels,with marked temporal and spatial variations;of high-level EPC,58.26%was concentrated in eastern China.Six urban agglomerations(Beijing-Tianjin-Tangshan region,Shanghai-Nanjing-Hangzhou region,Pearl River Delta,Shandong Peninsula,middle-south of Liaoning Province,and Sichuan Basin)accounted for 10.69%of the total area of Chinese Mainland but consumed 39.23%of the electricity.(3)The EPC of most regions in Chinese Mainland increased from 1995 to 2008,and 64%of the mainland area showed a significant increase in EPC.Moderate increases in EPC were found in 61.62%of eastern China and 80.65%of central China from 1995 to 2008,whereas 75.69%of western China showed no significant increase in EPC.Meanwhile,77.27%,89.35%,and 66.72%of the Shanghai-Nanjing-Hangzhou region,Pearl River Delta,and Shandong Peninsula,respectively,showed high-speed increases in EPC.Moderate increases in EPC occurred in 71.12%and 72.13%of the Beijing-Tianjin-Tangshan region and middle-south of Liaoning Province,respectively,while no significant increase occurred in 56.34%of the Sichuan Basin. 展开更多

AIM To assess the validity and reliability of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Colorectal Cancer 29 (EORTC QLQ-CR29) in Chinese patients with colorectal cancer (CRC). METHODS From March 2014 to January 2015, 356 patients with CRC from four different hospitals in China were enrolled in the study, and all patients self-administered the EORTC QLQ-CR29 and the quality of life core questionnaire (EORTC QLQ-C30). Evaluation of the scores was based on the Karnofsky Performance Scale (KPS). The reliability and validity of the questionnaires were assessed by Cronbach's proportional to coefficient, the Spearman correlation test and Wilcoxon rank sum test. RESULTS The EORTC QLQ-CR29 showed satisfactory reliability (proportional to > 0.7), although the urinary frequency and blood and mucus in stool dimensions had only moderate reliability (proportional to = 0.608). The multitrait scaling analyses showed good convergent (r > 0.4) and discriminant validity. Significant differences were obtained for each item in the different KPS subgroups (KPS 80). Body image and most single- item dimensions showed statistically significant differences in patients with a stoma compared with the rest of the patients. CONCLUSION The EORTC QLQ-CR29 exhibits high validity and reliability in Chinese patients with CRC, and can therefore be recommended as a valuable tool for the assessment of quality of life in these patients. 展开更多

Objective To compare the characteristics of suicides in the four main demographic groups： urban males, urban females, rural males and rural females in order to help clarify the demographic pattern of suicides in China. Methods A detailed psychological autopsy survey instrument was independently administered to 895 suicide victims in family members and close associates from 23 geographically representative locations from around the country. Results Pesticide ingestion accounted for 58% （519） of all suicides and 61% （3181519） of deaths were due to unsuccessful medical resuscitation. A substantial proportion （37%） of suicide victims did not have a mental illness. Among the 563 victims with mental illness, only 13% （76/563） received psychiatric treatment. Compared to other demographic groups, young rural females who died from suicide had the highest rate of pesticide ingestion （79%）, the lowest prevalence of mental illness （39%）, and the highest acute stress from precipitating life events just prior to the suicide. Contusion Many suicides in China are impulsive acts of deliberate self-harm following acute interpersonal crises. Prevention of suicides in China must focus on improving awareness of psychological problems, improving mental health services, providing alternative social support networks for managing acute interpersonal conflicts, limiting access to pesticides, and improving the resuscitation skills of primary care providers. 展开更多

Swidden agriculture is by far the dominant land use system in the uplands of Southeast Asia （SEA）, as well as other tropical regions, which plays an important role in the implementation of Reducing Emissions from Deforestation and Forest Degradation （REDD） of United Nations. To our knowledge, the long-term inter-annual area of newly burned plots （NBP） of swidden agriculture in mainland Southeast Asia is still not available, let alone in the whole tropics. With the strengthening regional geo-economic cooperation in SEA, swidden agriculture has experienced and/or is still experiencing extensive and drastic transformations into other diverse market-oriented land use types since the 1990s. In this study, high-level surface reflectance products of Landsat 4151718 family sensors including Thematic Mapper （TM）, Enhanced Thematic Mapper Plus （ETM＋） and Operational Land Imager （OLI） acquired in March, April and May of each year between 1988 and 2016 were firstly utilized to detect and monitor the extent and area of NBP of swidden agriculture with multiple thresholds of four commonly-used vegetation indices, namely the Normalized Difference Vegetation Index （NDVI）, Normalized Difference Moisture Index （NDMI）, Normalized Burn Ratio （NBR） and Soil Adjusted Vegetation Index （SAVI）, in combination with local phenological features of swid- dening and topographical data. The results showed that： （1） an annual average of 6.08×104 km2 of NBP of swidden agriculture, or 3.15% of the total land area of MSEA, were estimated in the past nearly three decades. （2） Annual NBP were primarily distributed in four major geomorphic units including the Central Range of Hills, Northern Mountainous Region, West- ern Myanmar Hills, and Annamite Chain. （3） A decadal average analysis indicated that the NBP of swidden agriculture opened year by year declined as a whole, especially after 2010, merely with an average of 5.23×104 km2. （4） The top ten provincial administrative units in Cambodia, Laos, Myanmar, Thailand and Vietnam, which consistently accounted for over 90% of the newly opened swiddens of each country, showed distinct fluctuations in usingslash-and-burn practices in the last decades. The Landsat-based （30 m） reconstructed 29-year longitudinal updated maps （including extent and area） of the NBP of swidden agri- culture may contribute to REDD and local livelihood related studies in Continental Southeast Asia. Our study further demonstrated that the multiple vegetative indices thresholds approach holds great potential in detecting swidden agriculture in tropical mountainous regions. 展开更多

AIM:To investigate the current status of peritoneal carcinomatosis(PC) management,as well as the usage of cytoreductive surgery(CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC) in China's Mainland.METHODS:A potentially curative therapeutic strategy for selecting patients with PC,known as "Techniques",consists of CRS in combination with HIPEC.A systemic search of published works and clinical trials was performed.Additional papers were retrieved by crosschecking references and obtaining information from Chinese oncologists and relevant conferences.One hundred and one papers and one registered clinical trial on HIPEC were included.RESULTS:A literature review identified 86 hospitals in 25 out of all 31 areas of China's Mainland that perform HIPEC.The earliest report included in our survey was published in 1993.Different approaches to HIPEC have been utilized,i.e.palliative,prophylactic,and possiblycurative treatment.Only one center has consistently performed HIPEC according to the "Sugarbaker Protocol",which involves evaluating the extent of PC with peritoneal cancer index and the results of CRS with the completeness of cytoreduction.Positive preliminary results were reported:7 of 21 patients with PC survived,free of tumors,during an 8-43-mo follow-up period.Hyperthermic strategies that include HIPEC have been practiced for a long time in China's Mainland,whereas the "Sugarbaker Protocol/Techniques" has been only rarely implemented in China.The Peritoneal Surface Oncology Group International hosts a biannual workshop with the intent to train more specialists in this field and provide support for the construction of quality treatment centers,especially in developing countries like China,whose population is huge and has a dramatically increased incidence of cancer.CONCLUSION:To popularize Sugarbaker Protocol/Techniques in China's Mainland in PC management arising from gastric cancer or colorectal cancer will be the responsibility of the upcoming Chinese Peritoneal Surface Oncology Group. 展开更多

The relation between plate tectonics and earthquake evolution is analyzed systematically on the basis of 1998-2010 absolute and relative gravity data from the Crustal Movement Observation Network of China. Most earthquakes originated in the plate boundary or within the fault zone. Tectonic deformation was most intense and exhibited discontinuity within the tectonically active fault zone because of the differential movement; the stress accumulation produced an abrupt gravity change, which was further enhanced by the earthquake. The gravity data from China's Mainland since 2000 obviously reflected five major earthquakes （Ms 〉 7）, all of which were better reflected than before 2000. Regional gravity anomalies and a gravity gradient change were observed in the area around the epicenter about 2 or 3 years before the earthquake occurred, suggesting that gravity change may be a seismic precursor. Furthermore, in this study, the medium-term predictions of the Ms7.3 Yutian, Ms8.0 Wenchuan, and Ms7.0 Lushan earthquakes are analytically pre- sented and evaluated, especially to estimate location of earthquake. 展开更多

Monkeypox virus(MPXV),a DNA virus belonging to the Orthopoxvirus genus,causes a self-limiting zoonotic disease known as mpox.The human monkeypox infection was first recorded in a 9-month-old child in the Republic of Congo in the 1970s(Ladnyj et al.,1972).For a long time,mpox was mainly prevalent in the humid forests of Central Africa and parts of West Africa(Kabugae and El Zowalaty,2019).In recent years,MPXV has been spread to other countries through trade and travel.In 2003,a group of rare pets carrying MPXV was exported from Africa to the United States,and an outbreak of animal-to-human transmission occurred(Di Giulio and Eckburg,2004).In 2018,two cases of mpox were confirmed in travelers from Nigeria to the United Kingdom and one case was confirmed in Israel(Vaughan et al.,2018;Erez et al.,2019).Then,in 2019,one case was confirmed in Singapore(Ng et al.,2019).The outbreak of mpox in multiple non-endemic countries in North America and Europe started in May 2022(WHO,2022b).On July 23,2022,the WHO declared MPXV a Public Health Emergency of International Concern(PHEIC)(WHO,2022a).As of March 5,2023,86,309 confirmed mpox cases have been reported from 107 countriesegions worldwide(WHO,2023).In the mainland of China,the first imported case was confirmed by the Chinese Center for Disease Control and Prevention(Zhao et al.,2022),making this the fifth confirmed mpox infection in China.Neglected zoonotic mpox has been restricted in Africa but now it is back in the spotlight worldwide(Tan and Gao,2022). 展开更多

We have developed an automatic regional focal mechanism inversion system based on the Earthquake Rapid Report(ERR) system and the real-time three-component seismic waveform stream of 1 000 broadband seismic stations provided by the China Earthquake Networks Center(CENC). The system can rapidly provide a double couple solution and centroid depth within 5–15 min after receiving earthquake information from the ERR system.The data processing is triggered by earthquake information obtained from the ERR system. The system is capable of determining the focal mechanism of all shallow-depth earthquakes in the Chinese mainland with a magnitude of 5.5–6.5. It utilizes waveform data recorded by seismic stations located within 500 km from the epicenter,enabling the reporting of a focal mechanism solution within 5–15 min of an earthquake occurrence. Additionally,the system can assign a corresponding grade(A B C) to the focal mechanism solution. We processed a total of 301earthquakes that occurred from 2021 to June 2022, and after the quality control, 166 of them were selected.These selected solutions were manually checked, and 160 of them were compiled in a focal mechanism catalog.This catalog can be conveniently downloaded online via the Internet. The automatic focal mechanism solution of earthquakes in eastern China exhibits a good agreement with that provided by the Global Centroid Moment Tensor(GCMT), when available. The average Kagan angle between this catalog and GCMT is 22°, and the average difference in MWis 0.17. Furthermore, compared with GCMT, the minimum magnitude of our catalog has been reduced from approximately 5.0 to 4.0. The correlation between the centroid depth and crustal thickness in the Chinese mainland confirms the distribution of the centroid depth. 展开更多

The Chinese mainland is subject to complicated plate interactions that give rise to its complex structure and tectonics. While several seismic velocity models have been developed for the Chinese mainland, apparent discrepancies exist and, so far, little effort has been made to evaluate their reliability and consistency. Such evaluations are important not only for the application and interpretation of model results but also for future model improvement. To address this problem, here we compare five published shear-wave velocity models with a focus on model consistency. The five models were derived from different datasets and methods (i.e., body waves, surface waves from earthquakes, surface waves from noise interferometry, and full waves) and interpolated into uniform horizontal grids (0.5° × 0.5°) with vertical sampling points at 5 km, 10 km, and then 20 km intervals to a depth of 160 km below the surface, from which we constructed an averaged model (AM) as a common reference for comparative study. We compare both the absolute velocity values and perturbation patterns of these models. Our comparisons show that the models have large (> 4%) differences in absolute values, and these differences are independent of data coverage and model resolution. The perturbation patterns of the models also show large differences, although some of the models show a high degree of consistency within certain depth ranges. The observed inconsistencies may reflect limited model resolution but, more importantly, systematic differences in the datasets and methods employed. Thus, despite several seismic models being published for this region, there is significant room for improvement. In particular, the inconsistencies in both data and methodologies need to be resolved in future research. Finally, we constructed a merged model (ChinaM-S1.0) that incorporates the more robust features of the five published models. As the existing models are constrained by different datasets and methods, the merged model serves as a new type of reference model that incorporates the common features from the joint datasets and methods for the shear-wave velocity structure of the Chinese mainland lithosphere. 展开更多

The long-term earthquake prediction from 2021 to 2030 is carried out by researching the active tectonic block boundary zones in the Chinese mainland.Based on the strong earthquake recurrence model,the cumulative probability of each target fault in the next 10 years is given by the recurrence period and elapsed time of each fault,which are adopted from relevant studies such as seismological geology,geodesy,and historical earthquake records.Based on the long-term predictions of large earthquakes throughout the world,this paper proposes a comprehensive judgment scheme based on the fault segments with the seismic gap,motion strongly locked,sparse small-moderate earthquakes,and apparent Coulomb stress increase.This paper presents a comprehensive analysis of the relative risk for strong earthquakes that may occur in the coming 10 years on the major faults in the active tectonic block boundary zones in the Chinese mainland.The present loading rate of each fault is first constrained by geodetic observations;the cumulative displacement of each fault is then estimated by the elapsed time since the most recent strong earthquake. 展开更多

Submarine cable network is one of the most important connectivity infrastructures in the digital era.In the past 20 years,the submarine cable network of Chinese mainland has formed a complex connectivity structure.This paper focuses on exploring the structure and evolution of the submarine cable network of Chinese mainland.The results show that the evolution can be divided into four stages:an initial stage(1993-1998),a developmental stage(1999-2002),a stagnation stage(2003-2015)and an accelerated stage(2016-2018).The connectivity structure can be analyzed at micro,meso and macro scales.Statistically,the connectivity increased significantly overall,but showed significant differences in space.For the microscale,the landing cities were characterized by“extensive but low,exclusive and high”;for the mesoscale,the connectivity of countries or regions was characterized by“distance attenuation”as a whole,but,in part,by a“regional identity”;for the macroscale,intercontinental connectivity differences have been declining.The hierarchy has been upgraded from a“3 system”to a“2+3 system”.Finally,this paper discusses the interaction between submarine cable network construction and international relations,and puts forward policy suggestions for China’s submarine cable construction. 展开更多
