Development and external evaluation of predictions models for mortality of COVID-19 patients using machine learning method.

To predict the mortality of patients with coronavirus disease 2019 (COVID-19). We collected clinical data of COVID-19 patients between January 18 and March 29 2020 in Wuhan, China . Gradient boosting decision tree (GBDT), logistic regression (LR) model, and simplified LR were built to predict the mortality of COVID-19. We also evaluated different models by computing area under curve (AUC), accuracy, positive predictive value (PPV), and negative predictive value (NPV) under fivefold cross-validation. A total of 2924 patients were included in our evaluation, with 257 (8.8%) died and 2667 (91.2%) survived during hospitalization. Upon admission, there were 21 (0.7%) mild cases, 2051 (70.1%) moderate case, 779 (26.6%) severe cases, and 73 (2.5%) critically severe cases. The GBDT model exhibited the highest fivefold AUC, which was 0.941, followed by LR (0.928) and LR-5 (0.913). The diagnostic accuracies of GBDT, LR, and LR-5 were 0.889, 0.868, and 0.887, respectively. In particular, the GBDT model demonstrated the highest sensitivity (0.899) and specificity (0.889). The NPV of all three models exceeded 97%, while their PPV values were relatively low, resulting in 0.381 for LR, 0.402 for LR-5, and 0.432 for GBDT. Regarding severe and critically severe cases, the GBDT model also performed the best with a fivefold AUC of 0.918. In the external validation test of the LR-5 model using 72 cases of COVID-19 from Brunei, leukomonocyte (%) turned to show the highest fivefold AUC (0.917), followed by urea (0.867), age (0.826), and SPO2 (0.704). The findings confirm that the mortality prediction performance of the GBDT is better than the LR models in confirmed cases of COVID-19. The performance comparison seems independent of disease severity. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at(10.1007/s00521-020-05592-1).

Covering Covid-19 Pandemic on Short Video Platforms in China: A Content Analysis of Douyin Accounts of People's Daily and China Daily

As a new form of social media, short videos have been deeply seated in Chinese life. In order to expand their influence, China's mainstream media also opened accounts on short video platforms, especially during the Covid-19 pandemic. They use short video platforms to report news, which play a key role in guiding public opinion and stabilising people's hearts. Based on the pandemic coverage of two of China's representative media, People's Daily and China Daily on Douyin platform, content analysis method is used to analyse the reporting frequency, video length, reporting content, reporting tendency, and user engagement, and compare the similarities and differences between the two media in the above five aspects. It was found that in terms of reporting frequency, the development trend of the two media is different, but they post roughly the same number of videos per day on average, and the number of videos released during the pandemic is higher than usual. In terms of video length, most of the videos of the two media are produced in a duration of one minute. China Daily produced more long videos than People's Daily. In terms of the reporting content, the two media are involved in 11 constructed categories, but the top four categories are different because of the different position. About the reporting tendency, People's Daily has strong subjective emotion, and China Daily reported more neutral news. As for user engagement, People's Daily did better in likes, comments and shares, although both posted more likes, comments and shares than usual during the pandemic.

CT findings and dynamic changes of COVID-19 in the patients younger than 18 years old infected with SARS-CoV-2 omicron variant

Objective: To investigate the chest computed tomography (CT) manifestations and dynamic changes of coronavirus disease 2019 (COVID-19) in the patients younger than 18 years old infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant, and to provide a basis for determining the chest CT changes and efficacy of COVID-19 caused by Omicron virus variant in patients younger than 18 years old. Methods The clinical and imaging data of 30 cases of patients younger than 18 years old infected with COVID-19 Omicron variant, who admitted to the Third People's Hospital of Shenzhen from February 11 to March 26, 2022 were collected and retrospectively analyzed. The clinical manifestations, imaging features and dynamic changes of lesions were summarized. Results A total of 41 intrapulmonary lesions in 30 patients with COVID-19 caused by SARS-CoV-2 Omicron variant. The main manifestations were patchy or nodular ground-glass opacities and/or consolidation, with focal subpleural distribution, lesions mainly occur in the right lung (70.73%, 29/41). There were 42 lesion morphologies, with 22 (52.38%) striped shadows and 16 (38.10%) nodular shadows, with small lamellar and patchy shadows predominating. There were 36 lesion density variations, with ground glass shadows being the most common, with a total of 24 ground glass shadows (66.66%) in each lobe of the lung, and also 6 consolidation lesions (16.67%) and 6 mixed ground glass opacity and consolidation lesions (16.67%). With the progression of the disease, lesions gradually enlarged, appeared on the 2nd day (312.93 mm3), peaked on the 9th day (1 837.18 mm3). The average absorption time of the lesions was (16+or-3) days, and there was no significant difference between the absorption time of patchy and nodular lesions (ground glass and/or consolidation) (t=0.853, P > 0.05). The lesions showed focal ground-glass opacity in the early stage, 77.78% lesions were absorbed after treatment in the late stage. Inflammatory nodules were absorbed slowly (9-19 days), without residual fibrotic changes. Conclusions The imaging manifestations of COVID-19 in patients younger than 18 years old infected with SARS-CoV-2 Omicron variant have certain characteristics, showed patchy or nodular ground glass opacities and/or consolidation, mainly distributed in the subpleural area, with small and few lesions and slow change, didn't remain fibrosis. Being familiar with its clinical and imaging manifestations can assist in early diagnosis, but confirming the diagnosis requires a combination of epidemiological history, clinical symptoms, SARS-CoV-2 nucleic acid and radiological manifestations.

The clinical trial of patients improved from COVID-19: the effectiveness of mindfulness-based cognitive therapy on mental health and life expectancy (single-subject study)

Background & Aims: In early January 2020, a new corona virus called corona was identified as an infectious agent by the World Health Organization and caused a viral pneumonia outbreak, the first of which was reported in Wuhan, China in December 2019. The virus has so far infected most countries in the world and has become a global problem. By this time in December 2021, about 265 million people in the world have been infected with this virus and 5 million 270 thousand people have died from this disease. According to the World Health Organization, the incidence of this disease is still increasing and will become the third leading cause of death in the world by 2030. This disease has a special complexity and has multiple dimensions and consequences that have caused many problems in the field of health, social and economic as well as psychological for people. The emergence of this disease is now a public health crisis. According to this research, exposure to news and restrictions caused by this disease can lead to many mental health problems. In fact, one of the situations that puts a lot of stress on people during the outbreak of covid 19 disease is the inability to predict and uncertainty about the control and end of the disease. Mental health is defined as a harmonious and harmonious behavior with society, recognizing and accepting social realities, the power to adapt to them and meeting one's balanced needs and is an important factor for the health of society. The prevalence of the disease can also increase feelings of loneliness, decrease social support, feelings of fear and anxiety to clinical stress and anxiety, obsessive-compulsive disorder associated with the disease, and decreased life expectancy. One of the hopeful factors is health and the disease can cause despair, fear and even despair of the patient. The outbreak of a disease has a much deeper and wider impact and affects not only the affected community and relatives, but the entire community. Because everyone finds themselves at risk, and therefore people's feel of safe and healthy changes, and this situation causes people to despair. Hope is the capacity to imagine the ability to create paths to desirable goals and to imagine the motivation to move in those paths. Hope predicts physical and mental health such as positive response to medical interventions, mental health, effective getting along, and health-promoting behaviors. Covid 19 disease can also lead to psychological problems due to its infectious nature and unpredictable nature. In this regard, various researchers consider the implementation of public health policies, including areas related to individual and collective mental health in accordance with the different stages of the epidemic of this disease is very necessary. Mindfulness can be an effective tool for achieving peace of mind and body that helps people become aware of their current feelings. Mindfulness-based interventions are considered as one of the third generation or third wave cognitive-behavioral therapies. Mindfulness is a form of meditation rooted in Eastern religious teachings and rituals, especially Buddhism. Segal has defined mindfulness as paying attention to specific and purposeful ways, in the present time, without judgment or prejudice. Linhan stressed for the first time the need to pay attention to mindfulness as one of the essential components of psychological therapy. Mindfulness requires the development of three components: judgment avoidance, purposeful awareness, and focus on the present moment. Focusing on the present and processing all aspects of the above experience makes one aware of the daily activities and automatic functioning of the mind in the past and future world and he controls emotions, thoughts, and physical states through moment-to-moment awareness of thoughts. As a result, it is released from the everyday and automatic mind focused on the past and the future. Although general vaccination has reduced the virus in some countries, including Iran, and reduced the number of infected people, a large num

Decoding the rise of Central Bank Digital Currency in China: designs, problems, and prospects

During the Covid-19 pandemic, there has been a rapid shift in global transaction patterns from offline to online digital payment models, along with a growing interest in the development of Central Bank Digital Currencies (CBDCs) in various countries. This article spotlights the unexamined issue of digital currency regulation by examining the practice and related regulatory rules of the pilot CBDC in China. Beginning with the global design choices of digital currencies, the article comparatively examines the technical design of China's CBDC, known as e-CNY. It further triggers a rethinking of conventional regulations for the protection of digital currency information by investigating the gap between the actual operation and design of e-CNY, as well as the gap between pilot policies and legal provisions such as the Cybersecurity Law, the Data Security Law, and the Personal Information Protection Law. This article argues that, on the one hand, the legislative balance between the protection of personal information and the regulation of illicit financial activities involved in the "loosely coupled account link” system of e-CNY should be reconsidered. On the other hand, the delineation of rights and responsibilities between dissemination institutions, payment service providers, and end-users needs to be further redefined and clarified.

The French automotive industry faces the challenge of the ecological transition

[...]the vehicle of the future must be considered within the broader framework of the mobility of the future, taking into account the entire value chain. Transforming our future into a sustainable future: planning for the automotive transition Didier Sepulchre de Condé, Mechanical industry The automotive industry is in turmoil, firstly because of the economic situation, with a market deeply affected by Covid, shortages of materials and components and disoriented customers;and secondly because of the structural situation, with the forced transition to electrification. The four paradoxes of the ecological transition of the European car industry Alois Kirchner, Former Director of Cabinet of the Minister for Industry The energy transition in the automotive sector is essential for achieving French and European climate objectives. [...]the actions implemented come up against four paradoxes, which must be overcome if this transition is to succeed: * the regulation on the reduction of CO2 emissions from the tank to the wheel, to the exclusion of other sources which now represent the majority of emissions from new vehicles;* the steering of vehicle traffic restrictions based on Crit'air stickers, leading to the prohibition of access to certain cities for vehicles that are more virtuous than others that are still allowed to enter;* the inability to implement policies to support the production of vehicles on European soil that are sufficiently powerful to halt the fall in associated jobs;a situation that benefits production sites that are not subject to the same environmental standards;* and the rising price of "green" vehicles, leading to a slowdown in the renewal of the fleet and the maintenance of a high level of pollution and carbon emissions.

Characteristics of viral shedding in people infected with SARS-CoV-2 during difference stages

Viral shedding of SARS-CoV-2 is a continuous dynamic process, which can be divided into latent stage, initial stage, peak stage and decreasing stage according to the characteristics of viral shedding. After being infected with SARS-CoV-2, the infected person generally stays in the latent period for 1-3 days, which is characterized by continuous negative nucleic acid test results and no infectiousness, and the risk of infection for close contacts is very low. At the initial stage of viral shedding is characterized by a rapid decline in the Ct value of nucleic acid tests in a short time, and clinical symptoms gradually appear. The infectiousness of the infected person gradually increases during this period, and the risk of infection for close contacts also gradually increases, but it is still in the early stage of infection, the possibility of viral shedding is low, and the risk of infection of secondary close contacts is low. The peak of viral shedding is characterized by low Ct value in nucleic acid test and obvious clinical symptoms;during this period, the infected person is the most infectious, and the risk of infection of the contact is the highest, so the scope of close contacts should be expanded appropriately. The decreasing period is characterized by the gradual increase of Ct value of nucleic acid test and the gradual disappearance of clinical symptoms;during this period, the infectiousness of the infected person gradually decreases to disappear. In an outbreak, an infected person in the decreasing phase is more likely to be an early infected person in the transmission chain. If infected individuals in the decreasing phase are found in an area without a SARS-CoV-2 epidemic, it suggests that the local outbreak epidemic has been spreading for some time and may be larger in scale. According to the characteristics of viral shedding, risk personnel can be determined more scientifically and accurately, so as to minimize the risk and reduce the waste of epidemic prevention resources.

SCI-indexed papers and research hotspots of provincial centers for disease control and preven tion in China from 2011 to 2020

[Background] The COVID-19 pandemic hints at the importance of modernizing disease control system. To understand the scientific research strength of our country's disease control system in recent years is conducive to formulating more targeted policies or measures to promote the modernization of the disease control system. [Objective] To understand the scientific research strength and research hotspots of China's provincial-level centers for disease control and prevention (CDCs) from 2011 to 2020, and provide evidence for the development of scientific research work, discipline construction, and talent team construction in CDCs in the future. [Methods] The Science Citation Index Expanded (SCIE) and Social Science Citation Index (SSCI) of the Web of Science Core Collection were used to retrieve SCI-indexed English papers published by 31 provincial CDCs (excluding Taiwan Province, Hong Kong and Macau Special Administrative Regions) in our country from 2011 to 2020, and to screen literature with provincial CDCs as the first affiliation for bibliometric analysis and visual analysis. Bibliometric analysis included the SCI-indexed publications of different provincial CDCs (as co-affiliation and the first affiliation), the number of SCI-indexed papers published by provincial CDCs (as the first affiliation) and funding rates by years, the high-frequency authors of SCI-indexed papers published by provincial CDCs (as the first affiliation) and their distribution, and the characteristics of the journals. Visual analysis software Citespace 5.8.R1 was used to draw keyword co-occurrence maps, cluster information tables, and emergence maps to provide information on research hotspots and their evolution. [Results] From 2011 to 2020, the number of SCI-indexed papers from 31 provincial CDCs was 8 420 (including co-affiliation), of which 2 060 papers listed provincial CDCs as the first affiliation. The provincial CDCs of Zhejiang, Jiangsu, Shanghai, Beijing, Shandong, and Guangdong were the leading six institutes in terms of the total number of SCI-indexed papers contributed as co-affiliation or the first affiliation. There was a large gap in the total number of SCI-indexed papers among the provincial CDCs. The highest total number of SCI-indexed papers contributed by provincial CDCs as the first affiliation was Zhejiang CDC (448 papers), while the lowest number was Xinjiang CDC (only 1 paper). From 2011 to 2020, the total number of SCI-indexed papers contributed by the 31 provincial CDCs as the first affiliation showed an overall increasing trend. Except for 2011, which was 63.1%, the funding rates in other years exceeded 70%. In terms of high-frequency authors, 13 first authors published >=10 SCI-indexed papers: Zhang Yingxiu from Shandong CDC had the highest number of SCI-indexed papers (47), followed by Hu Yu from Zhejiang CDC. Zhejiang, Jiangsu, Beijing, Guangdong, Shanghai, and Shandong still ranked the top six of >=4 first authored-SCI papers. In terms of journal characteristics, the top 20 journals with the highest number of SCI papers published a total of 862 papers, accounting for 41.8% (862/2 060), and PLOS ONE ranked the first (188 papers). The research hotspots were mainly concentrated in the fields of infection, child health, and epidemiology. The main keywords of the first three cluster categories were related to the research fields of adolescent overweight and obesity, HIV, and vaccine immunity. The results of keyword emergence showed that research hotspots shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts. [Conclusion] The past ten years have witnessed increasing numbers of SCI-indexed papers published by provincial CDCs in our country and a stubbornly high funding rate. However, the gap among the provincial CDCs is still large seeing that economically developed eastern provincial CDCs published more SCI-indexed papers. Research hotspots have gradually shifted from overweight, obesity, and body mass index to antibodies, vaccines/vaccination, and cohorts.Copyright © 022 Shanghai Municipal Center for Disease Control and Prevention.

Higher levels of physical activity is associated with better walking ability and fall-related fitness of older adults during COVID-19 in China

This study analyzed the relationship of physical activity levels with walking ability and fall-related fitness in older adults in the Henan Provence, China. Physical activity levels of 288 older adults were assessed using the short form of the International Physical Activity Questionnaire. The participants were divided into low (LPAG, n = 81), moderate (MPAG, n = 106), and high physical activity groups (HPAG, n = 101). The 10-m walking test (10MWT), 3-m backward walking (3MBW), and Berg Balance Scale (BBS) were used to evaluate walking ability. Thirty seconds Sit to Stand Test (30SST), Time up and Go Test (TUGT), and figure-of-8 walk test (8WT) were evaluated for fall-related fitness. One-way ANOVA was used to detect between group differences, whilst Pearson's correlation was used to evaluate the relationship between total physical activity level and the measured variables. Logistic regression analyses were used to compute the odds ratios (ORs) of LPAG and MPAG relative to HPAG. There were significant differences between the groups for walking ability, 10MWT (p < 0.01), 3MBW, and BBS (p < 0.01), and also for variables of fall-related fitness, TUGT (p < 0.01), and 8WT (p < 0.01). Total physical activity levels had significant correlations with all variables except 30SST. In the walking ability, OR for 10MWT was 2.42 and 2.53 times for the LPAG compared to that for HPAG by model 1 and model 2. OR for BBS was 3.24 and 3.54 times for the LPAG and 9.31 and 9.65 times for the MPAG compared to for the HPAG by model 1 and model 2. In the fall-related fitness, OR for 8WT was 14.09 and 16.76 times for the LPAG compared to that for HPAG. High levels of physical activity are positively correlated with good walking ability and fall-related fitness. Increasing physical activity levels can reduce the risks associated with impaired walking ability and fall-related fitness.Copyright ©2023 The Author(s). Published by MRE Press.

APPLICATION AND FEASIBILITY OF VARIOUS TEACHING TOOLS USED IN ONLINE CLASSES DURING COVID-19 IN TERTIARY EDUCATION

The study compares the effectiveness, popularity, and ease of applicability of different learning tools in virtual classrooms among university teachers and students concerning the users' technological literacy and training, as well as equipment support offered by the universities during the pandemic. Comparisons between face-to-face teaching in classrooms and online virtual classrooms will be drawn concerning limitations, incentives, motivation, and effectiveness toward learning. This study also leads to the question of future course development by exploring the possibility of course design and assessment restructuring with a switch to online education with the new mode of technology as the trend.

Forging organizational resilience through green value co-creation: The role of green technology, green operations, and green transaction capabilities

The study assessed the mediating role of green organizational capabilities (green technology development, green operations, and green transactions), in the relationship between green value co-creation and organizational resilience among Chinese manufacturing firms, that is, firms' ability to build strong organizational resilience in response to the COVID-19 pandemic. It focused on manufacturing firms operating within Shenzhen, a coastal city located within the Guangdong province in southeastern China. The sample comprised 234 firms. Data were analysed using a covariance-based structural equation modeling. Findings revealed that green value co-creation had no direct effect on organizational resilience, rather, its effect was realized indirectly through green organizational capabilities. The study concludes that manufacturing companies can augment their organizational capabilities by leveraging the knowledge of their customers through green value co-creation to build strong organizational resilience. Theoretical and managerial implications have been provided.

Continuance intention in financial technology: a framework and meta-analysis

PurposeAlthough many studies have sought to address the topic of continuance intention among Fintech customers, the reported findings are fragmented. Therefore, the present study proposes a research model that integrates the main constructs involved in Fintech continuance intention.Design/methodology/approachThe current study uses a meta-analytic-based correlation analysis of effect sizes, meta-regression analysis and meta-analytic structural equation modeling, with 247 effect sizes in 69 studies involving 26,140 respondents.FindingsThe results reveal continuance intention is driven by satisfaction and trust, with ease of use and usefulness being antecedents of satisfaction and trust. The authors also found evidence to show satisfaction partially mediates the relationship between ease of use and continuance intention and that trust fully mediates the relationship between ease of use and continuance intention and partially mediates the relationship between usefulness and continuance intention. In addition, the authors found that in Western countries, with higher Human Development Index levels and greater of use of electronic payment, satisfaction has more impact on continuance intention.Practical implicationsFrom a theoretical standpoint, this meta-analytic study has implications for the literature on Fintech by offering an empirical generalization on the strength of the antecedents of Fintech continuance intentions and by testing possible moderators in a wide range of countries and studies. In other words, this study's goal is to broaden the scope of the research. Regarding managerial implications, it is important to listen to user opinions regarding the positive and negative points of their experience with these technologies and take them into consideration when planning improvements. Additionally, the analysis shows the importance of using data from user interaction with technology, obtained, for example, through big data analytics, whereby companies can see how users behave, how much time they spend accessing certain functions and which technological features they use most, and thus seek to improve whatever is needed.Originality/valueThis meta-analytic study advances the understanding of Fintech continuance intentions. Using the proposed approach, it is possible to generate accurate estimates of the effect size of each analyzed antecedent as the meta-analytic method jointly evaluates the results produced by a wide variety of studies performed in different contexts, allowing more accurate conclusions to be drawn.

COVID-19: Redefining India-China Bilateral Relations

In a bid to protect their national interest, every nation looks to strike a chord with other nations while maintaining commiserate prominence on a global scale. However, certain events could sway the direction in which international relations tilt at certain points in time. For instance, the COVID-19 pandemic has globally shifted and reshaped the various spheres of human life and activities. The pandemic gave rise to fears across the world and increased acts of hostility toward nations worldwide, in a bid to cater to and uphold their national interests, which they often achieve at the detriment of others. Specifically, China has been at the forefront of hostility or pressure, since the coronavirus originated there. Focusing on the Sino–Indian relationship, the rapid boom of Sino-Indian bilateral trade at the beginning of the 21st century propelled China to become India's biggest trade partner, a position it held from 2008 to 2019, before tensions arose between both nations. This study aims at examining the present state of Sino–Indian relations and reviews the impact of the COVID-19 pandemic on this relationship. To appropriately fulfill the objective of the study, an exploratory design was adopted. The study concludes that the COVID-19 pandemic has caused a disruption in every facet of human life and has created uncertainty about what the future holds for certain sects, organizations, and even nations—based on this, international relationships amongst nations may be affected negatively or positively depending on how governments and world bodies manage and respond to the situation. © 2023 DSR Publishers/ The University of Jordan.

Creative compliance and selective visibility: How Chinese queer uploaders performing identities on the Douyin platform

The growth in video-sharing social media platform use has changed modes of communication, which has helped to improve the visibility of gender and sexual minority groups. This tendency became evident given the social distancing during the COVID-19 pandemic. Likewise, the use of these platforms empowers LGBTQ individuals living in China to share knowledge and experiences, receive social and emotional support and so on. Previous studies rarely interrogate Chinese queer groups' socially sanctioned performance of identities on popular video-sharing platforms such as Douyin. This article undertakes a preliminary discussion of that research gap. It examines the conditions that enable such activities and concludes with a discussion of the strategies and methods that Chinese queer uploaders use in the process. Simply put, this article explores how the queer uploaders accommodate and negotiate their identity performances within a heterosexual and mainstream popular social media environment.

Research highlights on kidney transplantation in 2021: Voices from China

Over the past 70 years, kidney transplantation has become not only the most mature but also the highest-success-rate surgery among all organ transplantation surgeries. However, the long-term survival of kidney transplant recipients is still challenged by such key factors as ischemia-reperfusion injury related to kidney transplantation, rejection, chronic renal allograft dysfunction, renal allograft fibrosis, immunosuppressive therapy, infections and others. Relevant fundamental and clinical studies have emerged endlessly. At the same time, the research related to kidney transplantation also becomes a new hot spot accordingly in the context of the normalization of novel coronavirus pneumonia. This article reviewed the cutting-edge hot spots in relation to the fundamental and clinical aspects of kidney transplantation together with relevant new techniques and new visions. The studies included in this article focused on the reports published by Chinese teams that are more applicable to the current situation of kidney transplantation in China, for the purpose of providing new thoughts and strategies for the diagnosis and treatment of kidney transplantation related issues in China.Copyright © 2022 Organ Transplantation.

Research highlights of renal transplantation in 2020: voice from China

Renal transplantation is the optimal approach to improve the quality of life and restore normal life for patients with end-stage renal diseases. With the development of medical techniques and immunosuppressants, the short-term survival of renal graft has been significantly prolonged, whereas the long-term survival remains to be urgently solved. Renal ischemia-reperfusion injury (IRI), acute rejection, chronic renal allograft dysfunction, renal fibrosis and other factors are still the major problems affecting the survival of renal graft. Relevant researches have always been hot spots in the field of renal transplantation. Meantime, 2020 is an extraordinary year. The novel coronavirus pneumonia (COVID-19) pandemic severely affects the development of all walks of life. Researches related to renal transplantation have also sprung up. In this article, the frontier hotspots of clinical and basic studies related to renal transplantation and the COVID-19 related researches in the field of renal transplantation in China were reviewed, aiming to provide novel therapeutic ideas and strategies.Copyright © 2021 Journal of Zhongshan University.

Research on price transmission in Chinese mining stock market: Based on industry

The strong impact of COVID-19 on the global mining market has caused severe fluctuations in the prices of mineral products and mining stocks. Meanwhile, geopolitical conflicts have exacerbated risks in minerals trade and mining stock transactions. In the face of uncertainties in the international economic landscape and volatility of stock prices, China, as the world's major mineral trading country, has become increasingly linked between its stock market and the mining economy. To clarify the characteristics of mining stock price fluctuations and the evolution of the transmission relationships, and identify the key nodes and main paths of price transmission, we select 100 Chinese mining stocks from January 2019 to October 2022, distinguish them according to the industry category, and use Granger causality test, minimum spanning tree model and complex network analysis method to study. The results show that: (1) Chinese mining stock prices have risen significantly since 2020, and there has been a "decoupling” phenomenon within the stock market, that is, the linkage between some mining stocks has weakened. (2) The stock price fluctuation characteristics and transmission effects of different mining industries are obviously different. Precious metal minerals (PM) have the most dramatic changes in price fluctuations, the most prominent hedging characteristics, and the rapid price response ability, which is the first to accept price transmission. rare earth and rare metal minerals (RE) are sensitive to price fluctuations and are usually the "leader” of the transmission path. Bulk non-ferrous minerals (BNFM) have the most stable price fluctuations and are closely related to other stocks, which is a "transit warehouse” in the transmission path. (3) The price transmission mechanism of Chinese mining stock market has gradually stabilized, and the main transmission paths of "Coal→Agricultural minerals (Agri)→BNFM→Steel” and "PM, Core minerals for new energy (NEM), and RE→BNFM” have been formed in 2022.
