The construction of a healthy China cannot be separated from the improvement of the national nutrition and health level， and the improvement and upgrading of the national nutrition and health level cannot be separated from a solid legal system and policy improvement. This paper studied the nutritional laws of the United States and Japan， analyzed and summarized the experiences of the two countries to improve the relevant laws and policies of our country， and to promote the construction of healthy China.

Promoting big data， artificial intelligence and other digital technologies to empower smart supervision is the only way to achieve the informatization of supervision in the new era， and to promote the modernization of national governance systems and capabilities. This article explores the development process and construction ideas of the market supervision informatization project （part of the National Health Commission）； analyzes the economic and social benefits of the project； some countermeasures and suggestions for reference are put forward for the problems exposed in network and data security， business collaboration and data sharing， and digital technology empowerment supervision services. The goal of the research is to point out the right and scientific guidance for the project， and make the project really useful and helpful for the market supervision. The final target is to improve the level of supervision informatization and promote the capacity building of supervision modernization， strengthen the modernization level of the governance system and capabilities， and improve the level of services for improving and guaranteeing people’s livelihood.

The brain vasculature has been increasingly recognized as a key player that directs brain development, regulates homeostasis, and contributes to pathological processes. Following ischemic stroke, the reduction of blood flow elicits a cascade of changes and leads to vascular remodeling. However, the temporal profile of vascular changes after stroke is not well understood. Growing evidence suggests that the early phase of cerebral blood volume (CBV) increase is likely due to the improvement in collateral flow, also known as arteriogenesis, whereas the late phase of CBV increase is attributed to the surge of angiogenesis. Arteriogenesis is triggered by shear fluid stress followed by activation of endothelium and inflammatory processes, while angiogenesis induces a number of pro-angiogenic factors and circulating endothelial progenitor cells (EPCs). The status of collaterals in acute stroke has been shown to have several prognostic implications, while the causal relationship between angiogenesis and improved functional recovery has yet to be established in patients. A number of interventions aimed at enhancing cerebral blood flow including increasing collateral recruitment are under clinical investigation. Transplantation of EPCs to improve angiogenesis is also underway. Knowledge in the underlying physiological mechanisms for improved arteriogenesis and angiogenesis shall lead to more effective therapies for ischemic stroke.

Purpose: To construct a training program for ICU nurses to manage artificial airway gasbags to prevent ventilator-associated pneumonia (VAP) and explore its application in ICU nurses.Methods: From January to March 2023, 17 experts were consulted using the Delphi method to construct the draft of the training program. 52 ICU nurses were selected from a third-level, first-class hospital in Henan Province. They received training using the program for 4 weeks. The training effects were evaluated by examining the theoretical knowledge, testing operation skills, and the ICU medical staff gasbag management knowledge-attitude-behavior questionnaire before and one week after the training in April 2023.Results: The coefficients of expert authority for the two round inquiries were 0.816 and 0.837, respectively. The coordination coefficient of expert opinions ranges from 0.2 to 0.3. The final training program for ICU nurses on managing artificial airway gasbags to prevent VAP was constructed and included 4 primary indicators, 25 secondary indicators, 47 tertiary indicators. After the training by the program, the scores of the ICU nurses' theoretical knowledge (before, 73.73 ± 8.54 VS after, 88.31 ± 6.29; t = 11.017, P< 0.001) and technical operation (before, 75.29 ± 7.48 VS after, 86.92 ± 4.72; t = 8.986, P< 0.001) were significantly increased. The total scores of the ICU nurses' knowledge-attitude-behavior on gasbag management (before, 76.67 ± 10.68 VS after, 109.04 ± 9.87; t = 19.916, P< 0.001) were also significantly increased compared to the performance before training.Conclusion: The training program for ICU nurses on managing artificial airway gasbags to prevent VAP based on the Miller pyramid model is scientific and practical and can enhance the knowledge-attitude-behavior level of ICU nurses. This training program constructed in this study can be recommended and applied after further verification for the ICU nurses to manage the artificial airway gasbags in order to reducing the occurrence of the VAP in the clinical practice.

The cellular redox state is essential for inhibiting ferroptosis. Progranulin (PGRN) plays an important role in maintaining the cellular redox state after ischemic brain injury. However, the effect of PGRN on ferroptosis and its underlying mechanism after cerebral ischemia remains unclear. This study assesses whether PGRN affects ferroptosis and explores its mechanism of action on ferroptosis after cerebral ischemia. We found endogenous PGRN expression in microglia increased on day 3 after ischemia. In addition, PGRN agonists chloroquine and trehalose upregulated PGRN expression, reduced brain infarct volume, and improved neurobehavioral outcomes after cerebral ischemia compared to controls (p < 0.05). Moreover, PGRN upregulation attenuated ferroptosis by decreasing malondialdehyde and increasing Gpx4, Nrf2, and Slc7a11 expression and glutathione content (p < 0.05). Furthermore, chloroquine induced microglial lysosome PGRN release, which was associated with increased neuron survival. Our results indicate that PGRN derived from microglial lysosomes effectively inhibits ferroptosis during ischemic brain injury, identifying it as a promising target for ischemic stroke therapy.
