In hypoxic-ischemic brain damage (HIBD), the programmed cell death known as ferroptosis is significantly activated. Microglial cells demonstrate a high level of sensitivity to iron accumulation. Understanding how to regulate the dual role of microglia and transforming the microglial ferroptosis to a moderate and controllable process has considerable implications for the targeted treatment in HIBD. This paper serves as an overview of microglia-mediated ferroptosis in HIBD as a disease model. We discuss various aspects centered around microglia, including pathophysiological mechanisms, polarization and functions of microglia, molecular mechanisms of ferroptosis, signaling pathways, and therapeutic strategies. The review aims to provide a reference for studies of ferroptosis in microglia.

National health standards involve all kinds of technical requirements formulated and numbered in accordance with the procedures and formats stipulated in the standardisation system for the implementation of national health and hygiene laws, regulations and policies, and the protection of human health. The establishment of health standards in China should align with our legal framework, including laws, regulations, departmental rules, and health and hygiene policies. During the development of these standards, a comprehensive approach is advocated, encompassing in-depth investigations, rigorous demonstrations, and extensive stakeholder engagement. However, the process of standard formulation may suffer from insufficient research evidence. The evidence-based concept emphasizes the significance of evidence. Therefore, integrating evidence-based concept into the process of developing health standards can enhance the quality and scientific basis of these standards. This article systematically elucidates the current status and development process of health standards in China, explores the necessity and feasibility of incorporating evidence-based concept into the development of these standards, analyzes the challenges and opportunities, and presents reflections and suggestions.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:To explore the role of arginine metabolism in the inflammatory response to influenza A virus (FluA) infection.Methods:Eighteen-month-old mice were infected with FluA via nasal drip, with samples collected on the 6th day post-infection. The concentration of cytokines was determined by the Luminex multifactor assay, while the metabolites in bronchoalveolar lavage fluid (BALF) were analyzed using targeted metabolomic method. Correlation analysis was employed to examine the correlation between cytokines and metabolites. Macrophages were infected with FluA at a multiplicity of infection (MOI) of 1 and cultured with different concentrations of arginine for 24 h. The mRNA and protein expression levels of interleukin (IL)-1β, IL-6, tumor necrosis factor α (TNF-α) and IL-10 were detected by real time fluorescence quantitative RT-PCR (qRT-PCR) and Cytometric Bead Array (CBA).Results:In comparison to the control group, the levels of surfactant protein D (SP-D), TNF-α, monocyte chemotactic protein-1 (MCP-1), IL-1α, IL-6, IL-10, recombinant S100 calcium binding protein (S100) A9, interferon inducible protein 10 (IP-10), macrophage inflammatory protein-1α (MIP-1α), matrix metalloprotein-9 (MMP-9), and Complement Factor D in BALF of FluA infection exhibited a significant elevation. The concentrations of arginine, aspartate, citrulline, glutamic acid, ornithine, proline, creatine, and sarcosine in arginine metabolism were up-regulated, which was correlated with most of elevated cytokine levels. The supplementation of arginine after FluA infection significantly decreased the levels of IL-1β, IL-6, and TNF-α, but increased the level of IL-10 in macrophages.Conclusions:Arginine reduces the inflammatory response induced by FluA infection in macrophages, suggesting that it may be a potential intervention target for severe pulmonary inflammation following FluA infection.

Professor Zhang Zhiyuan, a master of Chinese medicine, made good use of Baizhu (Atractylis macrocephala (Koidz.)). Except for defecation in clinical practice, he usually prescribed processed Baizhu after stir-frying with soil. Baizhu is good at excreting water and removing dampness, so applied it in the formula series with Fuling (Poria cocos) and Guizhi (Cassia Twig) or self-made decoction for diarrhea. High-dose Baizhu could be used for edema by treating obstructive syndrome with tonics, so Baizhu were added in self-made Shugan Qushui Decoction (疏肝祛水汤) or modified Lizhong Decoction (理中汤) for liver cirrhosis ascites. It was emphasized that Baizhu could eliminate phlegm, so added it in modified Zexei Decoction (泽泻汤) for excess syndrome of vertigo. It was also acknow-ledged that Baizhu could strengthen the spleen and stomach, and was suitable for deficiency or excess syndrome of abdominal distension, so applied it in Burun Decoction (补润汤) for abdominal distension with deficiency-excess in complexity, and applied it in Zhizhu Decoction (枳术汤) or self-made Tiaozhong Decoction (调中汤) for deficient abdominal distention.

To summarize Professor ZHANG Zhiyuan's experience in treating leukorrheal diseases based on syndrome differentiation. It is believed that the main pathogenesis of leukorrheal diseases includes mainly depression, dampness and deficiency. Leukorrheal diseases can be classified into four syndrome types: syndrome of stagnation of liver qi and spleen deficiency, syndrome of internal retention of damp-heat, syndrome of cold-dampness invading downward, and syndrome of kidney yang deficiency. The treatment approach focuses on restoring the ascending and descending opening and closing of qi, regulating the liver and spleen to promote yang qi respectively. The four types of syndromes correspond to the application of four different herbal formulas: By using the combination of Danggui Shaoyao Powder (当归芍药散) from the Synopsis of Golden Chamber (《金匮要略》) with wind-dispelling herbs, adjustments are made to harmonize the liver and spleen; By applying modifications to the Baxian Drink (八仙饮) from the Obstetrics Enlightenment (《产科发蒙》) to clear heat and promote diuresis; A self-designed Shiwei Wendai Decoction (十味温带汤) is adjusted to warm the yang and dispel cold; The Baji Tusi Decoction (巴戟菟丝汤) from the New Compilation of Effective Recipes (《验方新编》) is adjusted to tonify and warm the kidney yang.

This parer summarized the clinical experience of Professor ZHANG Zhiyuan in treating stroke sequelae from the perspective of regulating qi and blood. It is believed that the basic pathogenesis of stroke sequelae is disharmony of qi and blood, and it is advocated that the basic treatment method is to regulate qi and blood. For the three major symptoms of stroke sequelae, including hemiplegia, cognitive dysfunction, and sluggish speech, the effective formulas have been summarized. Hemiplegia is often treated with Chongsu Qiju Decoction (重塑起居汤) to tonify the center and replenish qi, activate blood and dredge collaterals. Cognitive dysfunction is often treated with modified San Hua Decoction (三化汤) to resolve phlegm and purge heat, regulate qi and tonify blood. And sluggish speech is often treated with Zishou Jieyu Decoction (资寿解语汤) to warm and tonify yang qi, expel wind and remove phlegm. Meanwhile, the self-made Zhinao Huayu Decoction (治脑化瘀汤) is used to prevent the occurrence of stroke sequelae, and to regulate the blood and qi by using wind medicinals and the method of relaxing and purging bowels to cure the disease.

OBJECTIVES:
Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model.
METHODS:
The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention.
RESULTS:
The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful.
CONCLUSIONS
Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.
