The red doctor spirit is the red gene formed and developed in the process of the Communist Party of China （CPC） leading the revolution and construction， and in pioneering and developing the people’s health undertakings. It is also the embodiment of the spiritual lineage of the Chinese Communists in the field of healthcare. The red doctor resources is a valuable resource for medical colleges and universities to conduct ideological and political education， playing a vital role in the cultivation of medical talents and the construction of Chinese-style modernization in health and well-being. Combining with the macro-historical background and adopting the method of “university founding background， typical figures， typical cases， and group portrayal，” the university history research team at Xi’an Medical University has excavated representative cases that demonstrate the connotation of the spirit of red medicine， namely “political firmness and excellent technology，” from the university’s history of arduous struggle in its establishment and development. This exploration shows the historical value and practical significance of the red doctor spirit as reflected in university history. On these foundations， the research team explored and carried out ideological and political theory courses and campus culture construction activities with the characteristics of medical universities， thereby enhancing the affinity and persuasiveness of ideological and political theory courses， promoting the in-depth dissemination of the red doctor spirit， and assisting in the construction of health and well-being culture.

To evaluate the therapeutic effect of baicalein topical preparation on atopic dermatitis, we first constructed two atopic dermatitis-like mouse models induced by calcipotriol and 1-fluoro-2,4-dinitrobenzene to assess their therapeutic effect with skin tissue staining and other experiments. It was found that topical preparation of baicalein could alleviate epidermal thickening of diseased skin tissues, repair damaged skin barrier proteins, and inhibit T helper 2 cells (Th2) infiltration and mast cell infiltration and activation in lesional sites. Cyberpharmacology was utilized to analyze whether baicalein could treat atopic dermatitis by interfering with multiple pathogenesis-associated pathways. Results indicated that baicalein reduced the mRNA levels of inflammatory factors and inhibited the phosphorylation of NF-κB p65 and STAT1 proteins in keratinocyte cells. Together, the topical preparation of baicalein may be effective in alleviating atopic dermatitis-like symptoms in mice by down-regulating the phosphorylation level of NF-κB in keratinocytes, thereby decreasing the expression of inflammatory factors in keratinocytes, which provides an idea and a theoretical basis for the topical preparation of baicalein for the treatment of inflammatory skin diseases such as atopic dermatitis.

Objective: To explore the effect of replacing rice bowls with trays on controlling the salt intake among school aged children, providing new evidence and insights for salt reduction intervention. Methods: From April to May 2024, 373 students from grades 4-9 at a boarding school in Guizhou Province were enrolled through stratified random cluster sampling, with one intervention class and one control class per grade. During the intervention period for one month, and the types of meals provided, pricing standards, and dining procedures shall remain consistent with daily operations, the intervention group ( n =181) compartmentalized trays for lunch and dinner, while the control group ( n =192) still used a rice bowl. Pre and post intervention assessments included 24 hour urine collection, questionnaire surveys, and physical measurements. The difference in differences analysis combined with multiple linear regression was used to analyze the changes in sodium intake and to evaluate the net effect of the intervention. Results: The post intervention 24 hour sodium intake in the intervention group was ( 2 222.6 ±1 013.6) mg, an increase of 94.6 mg from baseline, with no statistically significant difference ( t=1.10, P >0.05). In contrast, the post intervention 24 hour sodium intake in the control group was (2 080.5±895.7) mg, a decrease of 190.8 mg from baseline, showing a statistically significant difference ( t=-2.39, P <0.05). The difference in differences results indicated that after adjusting the model for factors such as gender, grade and dietary behaviors affecting sodium intake, the intervention group showed a net increase of 232.5 mg [ β(95%CI )=232.5(-40.3-505.2)] in 24 hour sodium intake compared to the control group, with no statistically significant net effect ( P >0.05). Conclusions Merely changing tableware is insufficient to control children s salt intake effectively. Based on continuous practical explorations and evidence based research grounded in the nudge theory, multi dimensional measures such as salt reduction education and the construction of a supportive environment should be integrated to form an intervention system that achieves synergistic and enhanced effects.

Objective: To investigate the impact of milk and egg supplementation on body composition and bone mineral density of rural primary school students in Yunnan Province, so as to provide a reference for developing targeted nutritional intervention strategies. Methods: In December 2023, a cluster sampling method was adopted to select students from grades one to three in four primary schools each from Jinggu and Shidian countys of Yunnan Province, as the intervention group (662 students). Additionally, two boarding primary schools were selected from each county based on the principle of matching scale and student numbers as the control group (455 students). Starting from April 2023, the intervention group received 200 mL milk and 50 g eggs during the break on school days for 8 months, while the control group maintained their usual diet behavior. Body composition was measured by using bioelectrical impedance analysis, and distal radial bone mineral density was assessed via dual energy X-ray absorptiometry in April and December 2023. The intervention effects were analyzed by using a difference in-differences approach. Results: The final measurements of body fat percentage, skeletal muscle mass and fat free mass of the intervention group and the control group of primary school students were significantly higher than the baseline values, and the net effect of milk and egg intervention on these body composition indicators was not statistically significant ( P >0.05, both before and after adjustment). In contrast, bone mineral density increased significantly by 0.02 g/cm 2 in the intervention group. The net intervention effect on bone mineral density was statistically significant ( β=0.02, 95%CI =0.00-0.04), and remained significant after model adjustment ( β=0.02, 95%CI =0.00-0.04) (both P < 0.05). Subgroup analysis showed statistically significant effects of the intervention among girls ( β=0.02, 95%CI =0.00-0.04), day students ( β=0.04, 95%CI =0.01-0.07), and students with normal nutritional status ( β=0.02, 95%CI =0.00-0.04) (all P <0.05). No significant effect of milk and egg supplementation was observed on body composition indicators (all P <0.05). Conclusions Milk and egg supplementation can improve bone mineral density among rural primary school students in Yunnan Province. It is recommended that rural school aged children should increase intake of milk and eggs to support growth and development.
