肥胖是一种以慢性低度炎症为特征的进展性疾病,与多种代谢性疾病的发生、发展密切相关。脂肪组织作为一种内分泌和免疫器官,可分泌多种生物活性物质及炎症因子,参与肥胖患者体内的代谢过程。减重手术是治疗病态性肥胖及相关代谢性疾病的有效方法之一,能够调节机体内的炎症反应、有效改善代谢状态。但减重手术对于炎症因子的作用如何,目前国内外的文献证据仍有争议。本文将系统阐述肥胖与代谢性炎症的关系以及减重手术对炎症因子的影响,旨在为肥胖代谢外科的诊疗过程提供参考。

Obesity is a progressive disease characterized by chronic low-grade inflammation,which is closely related to the occurrence and development of a variety of metabolic diseases．As an endocrine and immune organ,adipose tissue can secrete a variety of bioactive substances and inflammatory factors,which participate in the metabolic process of obese patients．Bariatric surgery is one of the effective methods for the treatment of morbid obesity and related metabolic diseases,which can regulate the inflammatory response in the machine and effectively improve the metabolic state．However,the effect of bariatric surgery on inflammatory factors is still controversial at home and abroad．This article will systematically explain the relationship between obesity and metabolic inflammation and the effect of bariatric surgery on inflammatory factors,aiming to provide a reference for the diagnosis and treatment process of bariatric surgery．

新生儿期的免疫系统发育阶段对维持新生儿健康至关重要,具有独特的免疫调节机制。近年来,人们越来越关注髓源性抑制细胞（MDSCs）在新生儿免疫调节中的作用。MDSCs是一类免疫抑制功能强大的异质性细胞群体,它们能够通过多种机制调节免疫应答。MDSCs在新生儿中的调节作用对防止过度免疫反应和促进免疫耐受至关重要,有助于预防新生儿期炎症性疾病,并对其后续健康产生积极影响。近期研究文献分析展示了MDSCs在新生儿免疫调节中的多种作用机制,包括在特定病理条件下的保护作用、与新生儿期炎症反应的相互作用,以及对长期免疫发展的潜在影响。因此,深入理解MDSCs在新生儿免疫中的角色,不仅有助于揭示其复杂的调节机制,也为制定新的预防和治疗新生儿炎症性疾病的策略提供了新的思路。

The developmental stage of the immune system during the neonatal period is crucial for maintaining neonatal health,characterized by unique immunoregulatory mechanisms．In recent years,increasing attention has been drawn to the role of myeloid-derived suppressor cells（MDSCs）in neonatal immune regulation．MDSCs represents a heterogeneous population of cells with potent immunosuppressive functions,capable of modulating immune responses through various mechanisms．The regulatory role of MDSCs in neonates is vital for preventing excessive immune reactions and promoting immune tolerance,thereby aiding in the prevention of neonatal inflammatory diseases and positively influencing subsequent health outcomes．Analysis of recent research literature reveals multiple mechanisms through which MDSCs contribute to neonatal immune regulation,including protective effects under specific pathological conditions,interactions with neonatal inflammatory responses,and potential impacts on long-term immune development．Therefore,a comprehensive understanding of the role of MDSCs in neonatal immunity not only helps elucidate their intricate regulatory mechanisms but also provides novel insights for developing strategies for the prevention and treatment of neonatal inflammatory diseases．

心肌梗死是由冠状动脉阻塞所引起的心肌缺氧坏死,其发病率和病死率居高不下。近年研究发现,利用组织工程手段仿生构建心肌微环境能有效改善心肌梗死区微环境,对心肌的再生能力有着重要的调控作用,能在一定程度上促进心肌再生,有望成为将来治疗心肌梗死的新方向。然而,由于对仿生心肌微环境和机体微环境交互作用、引发的生物学效应及作用机制不清楚,直接影响心肌损伤修复的过程和质量。因此,阐明仿生心肌微环境在心肌损伤修复过程中的交互作用过程及其介导的生物学效应迫在眉睫。该文系统性综述了仿生心肌微环境的构建策略及植入体内后介导的生物学效应,包括免疫调控效应、促血管再生效应以及再生协同效应等,为新型心肌补片的仿生设计和临床应用提供理论支持。

Myocardial infarction（MI）,arising from coronary artery obstruction resulting in hypoxic necrosis of myocardium,remains high morbidity and mortality．Recent studies have revealed that constructing myocardial microenvironment bionically through tissue engineering methods can effectively ameliorate the microenvironment in the infarcted area and exert a crucial regulatory role in myocardial regeneration,which promotes myocardial regeneration to a certain extent and holds promise for the treatment of MI．However,the interaction between biomimetic myocardial microenvironment and host microenvironment,as well as the triggered biological effects and mechanisms are not clear,which directly affects the process and quality of myocardial repair．Therefore,it is urgent to clarify the interaction process and biological effects mediated by the biomimetic myocardial microenvironment during myocardial repair．This review systematically summarizes the construction strategies of biomimetic myocardial microenvironment and their mediated biological effects after implantation,including immunomodulatory effects,pro-vascular regenerative effects,and regenerative synergistic effects,which provides theoretical support for the biomimetic design and clinical application of novel cardiac patches．

本文分析了广州市南沙区某公立医院人力资源管理现状,并基于SWOT分析法探索其发展策略。研究发现,该医院的人力资源管理具有成熟的管理体系和一体化管理的实施优势,但也面临财政支持不足和人才及岗位结构不均衡的劣势。政策支持与区域医疗资源扩展为其提供了重要的机遇,但日益增长的行业竞争和人才吸引与保留的难题构成了威胁。医院应优化管理架构,加强顶层设计,改善学科和人才结构,采取一体化与差异化发展策略,以构建高效的人才队伍,提升医院竞争力。本文通过对优势、劣势、机遇和威胁的综合分析,制定了针对性的管理对策,为同类医疗机构提供了参考。

This paper analyzes the current state of human resource management（HRM）in a public hospital in Nansha District,Guangzhou,and explores development strategies based on a SWOT analysis．The study reveals that the hospital’s HRM benefits from a mature management system and the implementation of integrated management．However,it also faces challenges such as insufficient financial support and an imbalance in the structure of personnel and positions．Policy support and the expansion of regional medical resources present significant opportunities,while increasing industry competition and challenges in attracting and retaining talent pose threats．The hospital should optimize its management structure,enhance top-level design,improve the discipline and personnel structure,and adopt integrated and differentiated development strategies to build an efficient talent team and enhance its competitiveness．Through a comprehensive analysis of strengths,weaknesses,opportunities and threats,this paper formulates targeted management strategies,providing valuable references for similar medical institutions．
