Background Identifying the factors constraining the coupling coordination of primary medical resource allocation and high-quality economic development are essential for targeted promoting the coordinated development of the two system coupling. However, there are little research on the influencing factors that hinders the level of coordinated development of coupling. Objective To compare and analyze the coupling coordination level and its hindrance factors between primary medical resource allocation and high-quality economic development in China during the "12th Five-Year Plan" and the "13th Five-Year Plan" periods, identify barrier factors, and predict the coupling coordination trend of the two systems during the "14th Five-Year Plan". Methods The research was conducted from July 2022 to May 2023. The evaluation index system was constructed using 17 indicators, covering three dimensions from the primary medical resource allocation system (health equipment, health technicians, and healthcare funding) and five dimensions from the high-quality economic development system (innovation, coordination, openness, shared development, and green development). Data were sourced from the 2012-2021 China Statistical Yearbook and the corresponding China Health and Family Planning Statistical Yearbook. The entropy value method and comprehensive evaluation function were employed to assess the allocation of primary medical resources and economic high-quality development during the "12th Five-Year Plan" and "13th Five-Year Plan" periods. The coupling coordination model was constructed to facilitate this analysis. In order to ascertain the level of coupling coordination, an obstacle function was established in order to diagnose and identify obstacle factors affecting the coupling coordinated development. Furthermore, a grey model was employed in order to predict the trend of the coupling coordination of the two systems during the "14th Five-Year Plan" period. Results The degree of coordination between the allocation of primary medical resources and high-quality economic development in China increased from 0.15 to 0.68 between the "12th Five-Year Plan" and the "13th Five-Year Plan" periods. This overall trend was observed to be increasing year by year. However, the coupling model exhibited a low level of coordination, despite the relatively fast growth rate. The main obstacles to the coupling level of primary healthcare resource allocation and economic high-quality development binary composite system in the "12th Five-Year Plan" and "13th Five-Year Plan" periods are health equipment, health technicians, shared and green development. The modified GM (1, 1) prediction model indicates that during the "14th Five-Year Plan" period, the coupling degree of the primary medical system and the economic development level system fluctuates around 1.00, and the whole system is in the stage of the coupling degree of coordination rises from 0.73 to 1.12, indicating a rising trend in the overall situation. Furthermore, the degree of relative development is greater than 1.20, which is indicative of an oversupply state. Conclusion In order to empower the development of grass-roots medical and health systems, it is recommended that the development concept of green sharing is recommended to promote the rationalization of medical resources from three aspects from promoting coordinated development of systems, improving the conditions of grass -roots medical facilities, opening up primary medical talents, and integrating primary medical resources.

In order to improve the environmental friendliness of the film stripping solution for printed circuit boards, through experimental research, the formula of the eco-friendly film stripping solution with inorganic alkali as the main component was determined to contain: inorganic base NaOH at 0.5 mol/L, film breaker diethylene glycolmonobutyl ether at 10 mL/L, surfactant alcohols R at 5 mL/L, tin protectant potassium citrate at 1 g/L, with the remainder pure water. The film stripping solution was found to be colorless and transparent, maintaining a stable state. Under the condition of a temperature of 50 ℃, the film was removed within 50～70 s, the size of the film ranged from 5 to 10 mm, the average tin thickness variable was less than 0.5 μm, and the ammonia nitrogen value was measured at 4.632 mg/L. Comparing the film stripping solution with products from the same production line, it was found that the film stripping performance of the two was extremely close. The eco-friendly film stripping solution exhibited lower ammonia nitrogen value and chemical oxygen demand(COD) values, which not only met production needs but also offered good environmental friendliness, thereby reducing the treatment cost of the film stripping waste liquid.

Both the International Mission for Prognosis and Analysis of Clinical Trials (IMPACT) and the Corticosteroid randomization after significant head injury (CRASH) models are globally acknowledged prognostic algorithms for assessing traumatic brain injury (TBI) outcomes. The aim of this study is to externalize the validation process and juxtapose the prognostic accuracy of the CRASH and IMPACT models in moderate-to-severe TBI patients in the Chinese population.

Background At present, the problem of regional imbalance and lack of fairness in the allocation of medical resources in China remains prominent. The report of the 20th National Congress of the Communist Party of China clearly stated that it is necessary to promote the expansion of high-quality medical resources and balanced regional layout. Objective To explore the specific path to improve the efficiency of medical resource allocation in China, and provide scientific reference for realizing the rational and high-efficient allocation of medical resources in China and promoting the equalization of basic public services. Methods The study was conducted from September 2022 to February 2023, and the data were derived from the 2021 China Statistical Yearbook and 2021 China Health Statistics Yearbook. The data envelopment analysis (DEA) method was used to measure the efficiency of medical resource allocation in 31 provinces of China in 2020, considering the number of healthcare institutions, health technicians, and beds as input indicators, the number of visits and admissions as output indicators. Fuzzy-set Qualitative Comparative Analysis (fsQCA) was used to explore the synergistic influence mechanism of internal and external factors on the efficiency of medical resource allocation from a group perspective, taking resource allocation efficiency as the outcome variable, the ratio of health technicians, number of beds per 1 000 population, average hospitalization days of discharged patients, gross domestic product (GDP) per capita, disposable income of the residents, the fiscal revenue decentralization, and ratio of the budgetary expenditures on healthcare as conditional variables, to analyze the conditional configuration of high or non-high level of healthcare resource allocation efficiency, and clarify the multiple paths of efficient and inefficient allocation of medical resources. Results In 2020, the overall level of medical resource allocation efficiency in 31 provinces of China is relatively high, with an average of 0.852, but there were large differences among provinces. The results of configuration analysis showed that the improvement of medical resource allocation efficiency is the result of multiple factors, there are three paths for efficient allocation of medical resources. Path 1: government-led driving path, taking Guangxi Zhuang Autonomous Region as a typical case; Path 2: internal and external coordination driving path, represented by Yunnan Province and Gansu Province; Path 3: balanced driving path, with Guangdong Province, Fujian Province and Hubei Province as representative cases. There are also three paths of non-high medical resource allocation efficiency. Path 1: government-restricted path; Path 2: economic-government dual restriction path, representative cases included Heilongjiang and Jilin Province; Path 3: internal and external constraints path, the typical cases were Shanxi Province and Tibet Autonomous Region. Conclusion The internal and external elements and synergies between elements jointly affect the allocation of medical resources in the process of benign interaction, it is necessary to optimize the internal and external environment, and effectively integrate the key resource elements to form a joint force to promote the rational allocation of regional medical resources.

Face forgery and detection has become a research hotspot.Face forgery methods can produce fake face images and videos.Some malicious videos, often targeting celebrities, are widely circulated on social networks, damaging the reputation of victims and causing significant social harm.As a result, it is crucial to develop effective detection methods to identify fake videos.In recent years, deep learning technology has made the task of face forgery and detection more accessible.Deep learning-based face forgery methods can generate highly realistic faces, while deep learning-based fake face detection methods demonstrate higher accuracy compared to traditional approaches.However, it has been shown that deep learning models are vulnerable to adversarial examples, which can lead to a degradation in performance.Consequently, games involving adversarial examples have emerged in the field of face forgery and detection, adding complexity to the original task.Both fakers and detectors now need to consider the adversarial security aspect of their methods.The combination of deep learning methods and adversarial examples is thus the future trend in this research field, particularly with a focus on adversarial attack and defense in face forgery and detection.The concept of face forgery and detection and the current mainstream methods were introduced.Classic adversarial attack and defense methods were reviewed.The application of adversarial attack and defense methods in face forgery and detection was described, and the current research trends were analyzed.Moreover, the challenges of adversarial attack and defense for face forgery and detection were summarized, and future development directions were discussed.
