Ultra-high-altitude females demonstrated higher TEWL, E, M, and b values, but lower CM, ITA, and L values compared with high-altitude females (<i>P</i> < 0.001), with statistically significant differences. Linear, correlation, and phenotypic network analyses showed that pH, CM, TEWL, ITA and L values were linearly correlated with altitude. The b values of both males and females showed a linear relationship with altitude, and the M value of females was linearly correlated with altitude.

In these diabetic mice with poorly-managed blood glucose, the expression of Ki67 in Treg cells was significantly upregulated (&lt;i&gt;P&lt;/i&gt; &lt; 0.05), while the apoptosis of non-Treg cells (Foxp3&lt;sup&gt;-&lt;/sup&gt; non-Treg cells) increased markedly (&lt;i&gt;P&lt;/i&gt; &lt; 0.05). Under high-glucose treatment conditions, the ROS levels in Teff cells increased significantly, and the cell apoptosis also increased significantly. High-glucose treatment induced the activation of transforming growth factor-β (TGF-β) and promoted the differentiation of Treg cells, whereas blocking the TGF-β signaling pathway or neutralizing ROS completely inhibited high glucose-induced Treg differentiation (&lt;i&gt;P&lt;/i&gt; &lt; 0.01).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Sustained hyperglycemic internal environment in poorly-controlled diabetic mice causes high level of ROS production in Teff cells by inducing oxidative stress, which leads to increased apoptosis of Teff cells, promote","PeriodicalId":39321,"journal":{"name":"四川大学学报(医学版)","volume":"56 3","pages":"603-612"},"PeriodicalIF":0.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12439653/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145081952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, medicine and healthcare have been primarily focused on a biomedical paradigm, with particular emphasis on the pathological mechanisms and treatment protocols of diseases. However, in recent years, there has been growing recognition that health is a holistic concept influenced not only by biological factors but also by psychological, social, cultural, and other factors, which leads to the emergence of medical humanities. Herein, we constructed a narrative community shared by physicians and patients through the frameworks of phenomenology, social design, and health design. By integrating narrative medicine with medical animation through storytelling and focusing on the feasibility study of an undergraduate course on medical animation, this study synthesizes the conceptual frameworks and methodologies of the humanities with health-related practices, integrating the theories and techniques of narrative medicine with those of medical animation. Through this interdisciplinary approach, we investigated innovative pathways in medical education, attempting to establish new foundations for a more comprehensive understanding and promotion of human health.</p>","PeriodicalId":39321,"journal":{"name":"四川大学学报(医学版)","volume":"56 3","pages":"887-892"},"PeriodicalIF":0.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12439662/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145081963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their &lt;i&gt;CYP3A5&lt;/i&gt; genotypes were determined. According to the different genotypes, the patients were assigned to two groups, the AA + GA group, or the rapid metabolism group with the genotype &lt;i&gt;CYP3A5&lt;/i&gt;*1/*1, i.e., AA + &lt;i&gt;CYP3A5&lt;/i&gt;*1/*3, and the GG group, or the slow metabolism group with the genotype &lt;i&gt;CYP3A5&lt;/i&gt;*3/*3. The basic information, clinical manifestations, history of other diseases, and medication history of the enrolled patients were collected. According to the principle of simple random grouping, patients in each group were randomly divided into two subgroups, receiving TAC at initial doses of 0.05 mg/(kg·d) and 0.075 mg/(kg·d), respectively. Data on laboratory test indicators, including TAC blood drug concentration, blood pressure, and other relevant clinical follow-up indicators, were collected each month from each group. Patients were also evaluated each month for their clinical remission status. When patients in the 0.05 mg/(kg·d) initial dose group did not achieve clinical remission after 2 months, the TAC dose was increased to 0.075 mg/(kg·d), and the patients were observed until the end of the 6th month. Patients in the 0.075 mg/(kg·d) initial dose group were observed for 6 months, regardless of their remission status.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In the LN patient subgroups receiving TAC at the same initial dose, the cumulative remission rate of patients with the GG genotype was higher than that of patients with the AA+GA genotype, but only in the 0.05 mg/(kg·d) initial dose group, the difference in cumulative remission rate between the two genotypes was statistically significant (&lt;i&gt;P&lt;/i&gt; &lt; 0.05). According to a comparison of patients with the same genotype who received TAC at different initial doses, the remission rate of patients receiving 0.075 mg/(kg·d) initial dose was higher than that of the 0.05 mg/(kg·d) initial dose group, but only in patients with AA + GA genotype, the difference in remission rate between the two initial dose groups was statistically significant (&lt;i&gt;P&lt;/i&gt; &lt; 0.05). Whether it was different genotypes in the same TAC initial dose group or different TAC initial doses of the same genotype, there was no statistically significant difference in the time to achieve complete remission (&lt;i&gt;P&lt;/i&gt; &gt; 0.05).

Studies have shown that FMD not only extends the lifespan and reduces the incidence of cancer and other diseases in healthy individuals, but also enhances the protective effects on normal cells. Furthermore, FMD increases the sensitivity of tumor cells to multiple therapeutic treatments. FMD activates the protective pathways of normal cells by lowering the levels of blood glucose, insulin, and insulin-like growth factor-1, while it induces differential stress sensitization of tumor cells, thereby enhancing the sensitivity of cancer cells to tumor therapy and providing new targets for individualized therapy. Herein, we provide a brief overview of the fundamental concept of FMD, the underlying mechanisms, and its potential application in cancer treatment, highlighting the synergistic effects of FMD applied in combination with conventional cancer therapies, such as chemotherapy and immunotherapy. Moreover, the challenges encountered in translating FMD into clinical practice are discussed, along with the promising future applications of this dietary regimen.</p>","PeriodicalId":39321,"journal":{"name":"四川大学学报(医学版)","volume":"56 3","pages":"873-880"},"PeriodicalIF":0.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12439641/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145081970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
