慢性萎缩性胃炎是常见的胃癌前病变,不仅治疗过程漫长,治疗难度大,而且患者依从性欠佳。不仅会对患者的生理、心理健康和生活质量造成严重不良的影响,还会给患者家属造成负担,成为临床上不可忽视的难题。但是本病发病机制目前尚未完全明确,临床治疗还未达成共识。文章综述了近10年基于Hedgehog信号通路的中医药干预慢性萎缩性胃炎的研究概况。中医药调控Hedgehog信号通路辨证论治是治疗慢性萎缩性胃炎的一种独具特色的疗法,近年来有关基于Hedgehog信号通路的中医药干预治疗慢性萎缩性胃炎的报道越来越多。文章主要通过遵循疾病本虚标实的病性,以脾胃虚弱为本,瘀血、气滞、湿热、痰浊等为标,探讨选方治疗对慢性萎缩性胃炎的影响,认为中医药联合Hedgehog信号通路实行现代化发展能够有效干预治疗慢性萎缩性胃炎,以期为进一步临床研究与应用提供参考。

Chronic atrophic gastritis,a common precancerous lesion of gastric cancer,requires a long-term treatment and is difficult to cure．Therefore,it usually leads to decreased patient compliance．It will not only have a serious adverse impact on the patient’s physical and mental health and quality of life,but also cause a burden to the patient’s family,which has become a difficult problem that can not be ignored clinically．However,the pathogenesis has not yet been totally clarified,not to mention a consensus on the clinical treatment．This paper reviews the research revolving around Chinese medicine intervention in chronic atrophic gastritis based on the Hedgehog signaling pathway in the last decade．It’s creative therapy of chronic atrophic gastritis that utilizing Traditional Chinese Medicine to regulate and control Hedgehog signaling pathway,which has been increasingly reported in recent years．This paper is based on “deficiency in origin” and “excess in superficiality” principle．Concretely,spleen-stomach vacuity is characterized by deficiency in origin,and excess in superficiality manifests blood stasis,qi stagnation,dampness-heat and phlegm turbidity as excess in superficiality．By this way,the paper explores the effect of prescription selection on chronic atrophic gastritis．It is believed that the modern therapy that combines traditional Chinese medicine with Hedgehog signaling pathway can tackle chronic atrophic gastritis,thus providing a reference for further clinical trials and practices．

炎症性肠病（IBD）作为一种慢性、易复发的炎症性疾病,被世界卫生组织归类为现代医疗领域的难治性疾病之一。其确切发病机制尚不清晰,目前主要认为与肠菌失衡触发宿主过度的肠黏膜免疫反应,进而在遗传易感性的个体中引发肠黏膜的损伤有关。目前,尚无特效的靶点能治愈IBD。过氧化物酶体增殖物激活受体（PPARs）作为核受体超家族的一员,在机体的生长发育、炎症调控以及代谢过程中扮演着重要角色,且被视为治疗包括IBD在内的多种疾病的重要潜在靶点,并被认为与肠道菌群关系密切。文章旨在探讨PPARs与肠道菌群的关系在IBD中的作用,从而挖掘IBD新的潜在诊疗靶点,开发新的治疗策略,为临床上IBD的诊断和治疗提供新的思路和方法。

Inflammatory bowel disease（IBD）,characterized as a chronic and recurrent inflammatory condition,is classified by the World Health Organization as one of the intractable diseases in modern medicine．The precise pathogenesis of IBD remains unclear,but current research widely believes that it is closely related to dysbiosis of the gut microbiota．Imbalance in the gut flora triggers an excessive immune response in the host’s intestinal mucosa,leading to mucosal damage in genetically susceptible individuals．To date,no specific targets have been identified that can cure IBD．Peroxisome proliferator-activated receptors（PPARs）,as members of the nuclear receptor superfamily,play significant roles in growth and development,inflammation regulation,and metabolic processes．They are regarded as potential effective targets for treating various diseases,including IBD,and are closely related to the gut microbiota．This review aims to discuss the progress in understanding the role of the relationship between PPARs and gut microbiota in IBD,so as to find new potential targets for the diagnosis and treatment of IBD,develop new treatment strategies,provide new ideas and methods for the diagnosis and treatment of IBD in clinical practice．

《流行病学》作为公共卫生与预防医学的主干课程,对于培养高质量公共卫生人才至关重要。在大数据、人工智能和互联网技术迅猛发展的时代背景下,传统的单一教学模式已无法满足现代医学教育的需求。线上线下混合教学模式逐渐成为高等医学教育的主要教学方式。这种模式结合了线上资源的丰富性和线下课堂的互动性,能够拓展教学内容,提高学生的自主学习能力。通过大数据分析和人工智能技术,可以提供个性化学习体验和实时反馈,优化教学效果。然而,这一模式在实际应用中仍面临诸如资源整合不够、师生互动不足等挑战。文章以广州医科大学为例,分析了《流行病学》课程中混合教学模式的优势与不足,并提出了针对性的改进建议。通过这些建议,旨在提升混合教学模式的有效性,为未来教学改革提供新的思路和参考。

Epidemiology,as a core course in public health and preventive medicine,is crucial for training high-quality public health professionals．With the rapid development of big data,artificial intelligence,and internet technologies,traditional single-mode teaching methods no longer meet the demands of modern education．The blended learning model,combining online and offline teaching,has gradually become a primary method in higher medical education．This model integrates the richness of online resources with the interactivity of offline classes,expanding instructional content and enhancing students' self-directed learning abilities．By leveraging big data analysis and artificial intelligence,personalized learning experiences and real-time feedback can be provided to optimize teaching effectiveness．However,this model still faces challenges such as inadequate resource integration and insufficient teacher-student interaction in practical application．This study uses a medical university as a case study to analyze the advantages and limitations of the blended learning model in epidemiology courses and proposes targeted improvement suggestions．The aim is to enhance the effectiveness of blended learning and provide new insights and references for future teaching reforms．
