BACKGROUND: The evaluation and management of cervical vascular pathologies before orthopedic manual therapy have great significance for reducing risks, ensuring patients’ interests and promoting optimal clinical decision-making. However, the research and exploration of this field in China are still in its infancy. In 2020, the International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) released the International Framework for Examination of the Cervical Region for potential of vascular pathologies of the neck prior to Orthopaedic Manual Therapy (OMT) Intervention: International IFOMPT Cervical Framework (2020). This framework has important references and guiding values for the clinical practice of cervical manipulation in China. OBJECTIVE: To integrate and interpret the core content of the framework, to provide a reference for the clinical practice of cervical manual therapy in China. METHODS: On the basis of a full study of the framework, the authors interpret the core content of the framework from eight aspects including clinical reasoning, patient history, planning the physical examination, physical examination, risk and benefit. Meanwhile, seven databases including PubMed, EMbase, Cochrane Library, CNKI, WanFang, VIP and China Biomedical Literature Service System databases were searched by computer to screen clinical practice guidelines and expert consensus on neck pain. Through longitudinal comparison of multiple high-quality guidelines and consensus, the authors combine with the clinical practice in China to carry out discussion and analysis. RESULTS AND CONCLUSION: This framework expounds the management strategy and implementation path of cervical vascular disease evaluation before cervical manipulation from multiple dimensions, suggesting that we should improve clinicians’ attention to cervical vascular disease evaluation before manipulation, and construct evaluation criteria and implementation path with Chinese clinical characteristics. Meanwhile, we should further carry out basic scientific research with multidisciplinary techniques and promote shared decision-making and teaching model innovation to achieve the best clinical decision.

Background and purpose: Follow-up data of 6 737 patients undergoing surgery for gastric cancer were collected based on hospital registration, and the 1-, 3- and 5-years observed overall survival (OS) rates and disease-free survival (DFS) rates were analyzed to provide real-world research evidence for the prevention and control of gastric cancer and policy making in China. Methods: A total of 6 737 gastric cancer patients who underwent surgical treatment at Fudan University Shanghai Cancer center from 2015 to 2020 were included in this study. Clinical information and the follow-up endpoint data were collected through medical records review, telephone visits and death registry data linkage. The last follow-up date was November 30, 2023. Kaplan-Meier method was applied in evaluating the 1-, 3- and 5-year OS rate and DFS rate, and survival data were described by different subgroups including age group, gender, treatment period, tumor staging, and pathological characteristics. Results: With a median follow-up time of 50.99 months, the 5-year OS rate of surgically resected gastric cancer patients was 70.37%, and 5-year DFS rate in I-III stage cases was 69.46%. The 5-year OS rates of stage I, II, III and IV were 94.32%, 82.56%, 51.01% and 23.97%, respectively. The differences in survival among patients with different age, tumor location, gross classification, Borrmann classification and Lauren classification were significant. Conclusion: Staging is an important factor directly affecting the survival of gastric cancer patients. Screening and early diagnosis and treatment in large population, especially high-risk group, should be strengthened to further improve the patients' survival. [ABSTRACT FROM AUTHOR]

Objective To investigate the relationship between frailty and social activity of the elderly in China, and to study the influencing factors of frailty in the elderly, so as to provide scientific basis for the healthy life of the elderly. Methods Based on 43 health related variables in China Health and Retirement Longitudinal Study (CHARLS) 2018 database, the frailty index (FI) was constructed to evaluate the frailty of the elderly. Binary logistic regression was used to explore the effect of social activity on the frailty of the elderly. Results A total of 1 519 elderly people aged 60 and above were included in the CHARLS 2018 database, including 401 frail elderly, with a frailty rate of 26.4%. The participation rate of the elderly in social activities was 48.5%, and there were 439 elderly people with high level of social activity, accounting for 28.9% of the total. After adjusting for confounding factors, the risk of debilitation in the elderly with high level of social activity was 41.9%, lower than that in those with medium and low level of social activity (0fl=0.581, 95%CH: 0.439-0.77). Conclusion The degree of social activity affects the frailty of the elderly, and the social activity of the elderly in China is generally low. The elderly should be encouraged to participate in social activities, and attention should be paid to the older and female elderly. [ABSTRACT FROM AUTHOR]

BACKGROUND: Lumbar intervertebral disc herniation is a common clinical disease. Its incidence is increasing year by year, which seriously affects the quality of life of patients and brings huge economic losses to the families of patients and society. At present, it is considered that the destruction of the integrity of intervertebral disc fibrous annulus is an important factor affecting the occurrence and development of lumbar disc herniation. Therefore, it is of great significance to restore the integrity of the annulus fibrosus for the treatment and prevention of lumbar disc herniation. OBJECTIVE: To review the research advance in intervertebral disc annulus repair in recent years. METHODS: PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and WanFang databases were searched systematically, with the key words “intervertebral disc, annulus fibrosus, repair, regeneration” in Chinese and English. Relevant articles published in each database in the last five years were collected. RESULTS AND CONCLUSION: In recent years, some progress has been made in the repair and regeneration of annulus fibrosus in and outside China. Although traditional physical repair has some shortcomings, it is still the main way of clinical treatment, while the application of tissue engineering in annulus fibrosus repair is only in the experimental stage and has not been widely used in clinical practice. There are many ways to repair intervertebral disc annulus fibrous, but the best way needs extensive animal and clinical trials to verify its safety and efficacy. The study on tissue engineering of annulus fibrosus repair has broad clinical application prospects. [ABSTRACT FROM AUTHOR]

Objective To explore the correlation between geriatric depression and its related factors, and to reveal their impact on depression through bayesian reasoning, ao as to achieve prevention and treatment of depression. Methods Based on the China Health and Elderly Care Longitudinal Survey (CHARLS)2018, this study employed the Depression Scale of the Center for Epidemiology (CES-D) to conduct a questionnaire survey on the depression of the elderly population, and incorporates it into demographics, health status, lifestyle, etc. Afterwards, Elastic Net was used to conduct a preliminary screening of 12,468 participants. Last, we used Bayesian networks with MMHC algorithm was constructed, and parameter learning was achieved by maximum likelihood estimation. Results Among the 12,468 participants, 5,035 (40. 38% ) participants were subjected to depression. After feature screening using Elastic Net, 9 variables finally entered the model, which was constructed with 10 nodes and 14 directed edges. The model showed that education levels, sleep duration, instrumental activities of daily living (IADL), and self -- reported health were directly related to depression, suggesting that there were parent nodes of depression occurrence. Conclusion BNs can well reveal the complex network connection between depression and its related factors, enabling the identification of direct or indirect risk factors for depression in the elderly. Accordingly, prevention and control of depression occurrence can be made in a targeted manner in the elderly, which provides a reference for reducing the risk of depression and improving the quality of life of the elderly.

To clarify the damage losses of invasive insects, the economic cost of global invasive insects were assessed in monetized form. InvaCost database was used to analyze all insecta data, and the conservative economic costs, expenditure costs, management and loss costs, and major invasive insect species from 1970 to 2017 were counted separately, based on which generalized least squares regression, robust regression, and quantile regression 3 models to predict the possible costs from 2010 to 2019. The results showed that the economic cost due to insect invasion from 1970 to 2017 was 500 438 million dollar, with an annual average of 10 426 million dollar. The United States had the highest spending cost in the world, and China ranked second about 50 352 million dollar (340 113 million yuan), and the economic cost of Aedes spp. was the highest among all invasive insect species. The model predicted a possible economic cost of 292.362~709.725 billion dollar in the 21st century 10s, with a maximum confidence value of 367.224 billion dollar. The assessment showed that the global economic costs of invasive insects over the past few decades had been enormous, but proactive management was clearly lacking. [ABSTRACT FROM AUTHOR]

Geo-relationships both constrain and foster the geo-economy, underscoring the importance of favorable geo-relationships for advancing geo-economic cooperation. Previous studies have analyzed the geo-relationships involving "the Belt and Road", but a gap remains in exploring the temporal and spatial evolution of these relationships among the countries involved. This paper employs the GDELT (Global Database of Events, Language, and Tone), an event database, to investigate the comprehensive characteristics and evolution of the geographic relationships between China and the countries along "the Belt and Road". The primary findings are as follows: ① The geopolitical relationship has transitioned through three stages: "cooperation priority, disagreements occur - cooperation increases, disagreements decrease-cooperation weakens, disagreements further decrease". ② A multi-category analysis reveals that within the geo-relationship between China and "the Belt and Road" countries, "speech augmentation events are concentrated in specific countries, while geopolitical segmentation events frequently occur in many countries". ③ From a multi-scale perspective, the geopolitical segmentation events on the national level exhibit an initial weakening followed by an increase, whereas the geopolitical augmentation events with neighboring countries display a recent downward trend. Analyzing the temporal and spatial evolution characteristics of the geopolitical relationship furnishes valuable insights for achieving a novel form of cooperation and a mutually beneficial relationship between China and "the Belt and Road" countries.

Zombie enterprises are an important source of overcapacity and pollution emissions. Accelerating the disposal of zombie en⁃ terprises is an important starting point for building a new development paradigm and promoting high-quality development and environ⁃ mental protection synergistically. Using the newly released 2006-2014 micro-matching data of China' s industrial pollution database and China' s industrial enterprise database and based on the measurement of the green total factor productivity of micro-enterprises, this study empirically tested the impact of zombie enterprises on green total factor productivity and its micro-mechanism. To alleviate the problem of data staleness, a cross-validation analysis was also carried out based on the identification of zombie enterprises in listed companies and the provincial green total factor productivity data from 2004 to 2018, and the conclusions were robust. The results showed that: ① Zombie enterprises not only had their own green total factor productivity lower than normal enterprises by 7.9%, but al⁃ so showed a significantly negative external green total factor productivity. That is, for each increase of 1 percentage point in the propor⁃ tion of zombie enterprises, the growth rate of green total factor productivity of normal enterprises would decrease by 2.733%. In the end, the existence of zombie enterprises caused the absolute level of overall green total factor productivity to drop by 3.27% and the relative level to drop by 22.4%. ② In the heterogeneous analysis, the negative externality of green total factor productivity of zombie enterprises was more significant for non-state-owned enterprises, small-scale enterprises, and enterprises with strong financing constraints. ③ In terms of the micro-mechanism test, zombie enterprises could inhibit the technological progress of normal enterprises, scale efficiency, and the growth of green total factor productivity. However, they had a certain short-term promotion effect on the pure technical efficien⁃ cy (management efficiency) of normal enterprises, and the micro-mechanism was more pronounced in the samples of non-state-owned enterprises, small-scale enterprises, and enterprises with strong financing constraints. The study also found that zombie enterprises sig⁃ nificantly reduced the labor productivity and environmental productivity of normal enterprises. In view of the conclusion, countermea⁃ sures and suggestions are put forward to speed up the disposal of zombie enterprises and promote high-quality development and environ⁃ mental protection in a coordinated manner.

With diverse crowns, beautiful flowers, colorful fruits, and leaves of different colors in the four seasons, Sorbus L. has a very high ornamental value in landscape. The genus is also one difficult taxa for taxonomic research arising from the combined effects of hybridization, polyploidy and apomixis. In this study, the specimens preserved in National Plant Specimen Resource Center and the database of Global Plants were retrieved and carefully sorted out. Some key information such as herbaria, collectors, collecting sites, collection time were analyzed concretely to understand the collection sites and the distribution center of wild germplasm resources of Sorbus in China and construct the database of Sorbus in China, so as to provide references for the first general survey and collection of forest and grass germplasm resources in China. On the basis of clarifying the distribution range and habitat of Sorbus plant resources, we found that the species of Sorbus in China are the most abundant in the world and Sorbus species are mostly distributed in high-altitude areas. Especially, more than half of Sorbus species are distributed in the mountainous area of southwestern China, and multiple ploidy coexists in this area, which creates unique conditions for hybridization. Is it the key factor of rich species diversity of this genus? With this, the research status of Sorbus plants were further summarized, the problems existing in the study of molecular system biology, conservation biology, phytochemistry and resource development and utilization were pointed out, and the key issues to be paid attention to in the future research of Sorbus were put forward. Suggestions for future research on Sorbus were as follows:(1)We should focus on the study of process of hybridization on the basis of a solid phylogenetic framework;(2)Based on the comprehensive investigation of the wild germplasm resources of Sorbus in China,, we should select the species with high ornamental value and study the molecular regulatory mechanisms of the response of Sorbus species to high-temperature stress in the summer in the low altitude areas by using the latest molecular biology techniques and methods, so as to provide a theoretical basis for the introduction and acclimatization of high-altitude species.

The southwest mountainous region in China is the worst-hit area due to the most developed geohazard chains. In order to better understand the pattern of the geohazard chains in this region, we analyzed the main control factors and characteristics of the geohazard chains based on 19 typical geohazard events in history. Three classification patterns, namely landslide-type, collapse-type, debris flow-type, and five typical hazard-inducing processes, were summarized. A typical hazard-inducing chain process in each model was selected for analysis. On this basis, we discussed the mechanism of the geohazard chain, the construction of a database and technical standard system, and the measures for preventing and controlling transboundary basin chain-type geohazards, aiming to provide a reference for the regional geohazard prevention and mitigation plan, and the major engineering projects' construction and people's safety in town.

(Objective) The China meteorological assimilation driving datasets is a database built up over the past decades specifically for application to the SWAT model (CMADS) in data-poor regions. This paper studies its application in upper reach of the Kaidu river in Northwestern China. (Method) We assessed two aspects. The first one is to assess the performance of the CMADS dataset in terms of estimating precipitation, maximum and minimum temperatures. The second is to compare the simulated results using the CMADS dataset and ground-true meteorological data.(Result) 1 The CMADS dataset is accurate for estimating temperature with its correlation with ground-true data being more than 0.9, but is less accurate for estimating daily precipitation, with its correlation with ground-truth data being 0.59. However, the correlation between calculated and measured monthly precipitations was high, reaching 0.84. 2 The simulated runoff using SWAT combined with CMADS dataset was in general more accurate than the results simulated using SWAT combined with the ground-truth data, indicating that, for regional hydrological modelling, CMADS dataset is more accurate than point-measured data. 3 Using the CMADS overestimated the baseflow and the lowest flow and underestimate the peak flow in model calibration stage, while underestimated the peak flow and overestimated baseflow slightly in model validation stage. In general, the runoff calculated using the CMADS was acceptable, except in a few extreme cases.(Conclusion) Testing the CMADS dataset against the upper reach of Kaidu river basin shows it is accurate and reliable. It can be used to simulate hydrological processes in regions short of measured meteorological data. [ABSTRACT FROM AUTHOR]

Apple and grape are the major cash-trees in China and their main producing areas are located in northern China. The common flood and drought disasters of apples and grapes are adopted as a case how to setup a comprehensive database for cash-trees' disasters with powerfull abilities, which required by the comprehensive prevention technology and the decision-making service platform, for disaster monitoring and early warning, risk assessment, as well as risk transfer in this study. The database is constructed by plentiful data collections and managements, strict data quality controls and multi-source data formats requirements, as well as detailed design for database overall schemes and database interfaces, by involving the open-source MySQL database building techniques with the C/S architecture. Multi-source and multi-type data are well managed by the comprehensive disasters database, such as long-term meteorological and hydrological data, cash-trees' disaster and orchard's producing management information, remote sensing data and its derived information, soil properties and basic geographic information, and so on. These multidiscipline data have been stored in different ways managed by the database system. For example, the quantitative/qualitative attribute data has been input into the database tables, whereas the vector and raster datasets have been kept in the computer operation file system formats and indexed by the database table. For the efficient data management and sharing, a sub-system for database managing activities is developed by using the database software developing tools under the supports of GIS function middleware and Quartz open-source components. Within the sub-system, the Role-Based Access Control (RBAC) model has been introduce to assign the database user's privileges and to control their behaviors for accessing the database tables. Meanwhile, many functions have been developed for task schedules, data collections and updates, data managements and storages, information statistical analyses and extractions, I/O ports accesses and model links from other platforms, as well as the basic data visualization abilities within the sub-system. Under the supports of the completely comprehensive disaster database, the early warning risk and disasters monitoring can been clearly illustrated in the cash-trees' producing areas by using the stored data and in terms of the preliminary disasters' indicators. Therefor, the successful case study of building up this comprehensive disasters' database contributes to promote other disaster database construction for cash-trees' except for apple and grape, or other disasters except for floods and drought, even or other areas except for northern China.

Cultivated land non-agriculturalization has been a major challenge for the food security in China. The spatial-temporal pattern and evolution of cultivated land non-agriculturalization can be one of the most important steps for the decision-making on land use. The high-resolution satellite images have been widely used in surface remote sensing monitoring. However, it is still lacking on the classification system of non-agricultural monitoring using remote sensing, due to the complexity and diversity of the cultivated land non-agriculturalization types. In this study, a classification system was proposed for the remote sensing interpretation samples of the cultivated land non-agriculturalization, in order to construct the corresponding remote sensing interpretation sample database. At the same time, a fast sample collection was also proposed to improve the efficiency and quality of the sample collection using geographical condition monitoring. As such, high temporal, spatial precision and attribute reliability were achieved to verify the feasibility and effectiveness of the classification system and sample collection. The Hubei Province of China was selected as the study area. Nine types of samples were collected in the cultivated land non-agricultural sample system. The geographical conditions covered the flatland, hill, mountain, high-mountain and other terrains. The sample library was formed after training the deep learning model. The Efficient Net deep learning network was selected to extract the spatial distribution of cultivated land non-agricultural in study area. The result showed that: 1) The sample collection using geographical condition monitoring performed the best in the attribute accuracy. The changing pattern was quickly and accurately located in the more efficient solution for sample collection. 2) The model accuracy was significantly improved, when the number of samples exceeded 5000. The accuracy was verified by the internal visual interpretation and field verification points in the verification area. The positive detection rates were 67.0 % and 76.5%, respectively, and the recall rates were 77.9% and 76.5%, respectively. 3) The sample classification system was also used to train the optimized model. There was a significantly improved accuracy of the non-agricultural cultivated land automatic identification in the study area, compared with the full factor sample training model. The positive detection rate of the five verification areas increased by more than 20 percentage points. Therefore, the classification system can be expected to improve the efficiency and accuracy of remote sensing monitoring of cultivated land non-agriculturalization using deep learning. The improved system can be applied to the seasonal remote sensing monitoring of cultivated land at the regional scale. [ABSTRACT FROM AUTHOR]

Based on the financial data of A-share listed companies in China from 2011 to 2019, the authors study the correlation between negative media reports, internal control and audit fees. The results show that the more negative media reports, the higher the audit fees charged by auditors. Further research finds that auditors charge higher audit fees for negative reports in high legal environments, while the relationship is not obvious in low legal environments; the weaker the internal control of enterprises, auditors charge more audit fees; internal control partially mediates the positive relationship between negative media reports and audit fees.

In order to examine the effects of urban construction land agglomeration on urban construction land-use efficiency, this paper adopted the stochastic frontier method to measure the urban construction land-use efficiency, based on the panel data of 278 cities in China from 2003 to 2017. The varied influence mechanisms of different degrees of urban construction land agglomerations on landuse efficiency were studied based on double fixed spatial Durbin model. The results showed that: ① From the perspective of spatio-temporal characteristics, the urban construction land-use efficiency in China generally reflected a trend of steady improvement during the study period, with the highest in the eastern region, followed by the western region and the lowest in the central region. ② Based on the regression results of national data, the scale effect and spillover effect induced by urban construction land agglomeration could improve the utilization efficiency of urban construction land. ③ Based on the analytical results of different groups, the direct effect of the highagglomeration cities (in the eastern developed region) implied that the improvement of urban construction land agglomeration could enhance the land-use efficiency. For the indirect effect, the promotion of construction land agglomeration in a city had an inverted Ushaped effect on the land-use efficiency of the surrounding cities. The direct and indirect effects of low-agglomeration cities (in the less developed regions in central and western China) indicated that the land-use efficiency was characterized by a U-shaped curve, accompanying with the improvement of urban construction land agglomeration. The results suggest that urban construction land agglomeration has a differentiated impact on urban land-use efficiency in different development periods. Therefore, policymakers should formulate differentiated land supply policies based on the characteristics of current development period in order to improve the urban construction land agglomeration. Moreover, policymakers should take targeted measures to enhance regional utilization efficiency of land in order to further sustain socioeconomic development. [ABSTRACT FROM AUTHOR]

In recent years,the emergence of mobile internet-based crowdfunding has provided a new way for the poor to obtain emergency relieves for medical needs. Despite a number of reported scams,medical crowdfunding as a wholes has made an important social contribution to the society. Public opinions and sentiment highlight two practical issues:Are the resources being directed to the people who need the most?And how can we optimize the crowdfunding?To tackle these questions,we focus on the issue of how the socioeconomic status of help seekers affect their internet fundraising outcomes. We ask three research questions:What is the correlation between the socio-economic status of help seekers and their crowdfunding effectiveness? What are the underlying mechanisms for success? Is there a possible optimization path for crowdfunding? Our data is based on the 1930 fundraising cases from a large medical crowdfunding platform in China. The study finds significant differences in effectiveness among different socioeconomic status groups. Higher SES status correlate with higher donation figures,fundraising target completions,a larger number of donations received and more cross-social media platform reposting. This socio-economic gradient phenomenon contradicts the social expectation of prioritizing help to the most needed in medical crowdfunding.The analysis of mediation effect also shows that the offline interpersonal network plays an important intermediary role. While good case narratives are helpful but they are not the intermediary mechanism that links the family’s socio-economic status and crowdfunding effect. Further analysis also finds that when fundraising begins with We Chat friends circles and then moves to public platforms,the impact of socioeconomic gradient seems to reduce its significance.
