Despite the fact that non-alcoholic fatty liver disease (NAFLD) and its severe clinical forms [non-alcoholic steatohepatitis (NASH) and NASH-cirrhosis] are highly prevalent in the general population, there are no licensed drugs for NAFLD, and lifestyle intervention remains the only treatment accepted by international guidelines. This is despite massive investments in research by pharmaceutical companies. In the presence of type 2 diabetes, novel anti-diabetic drugs offer an opportunity to reduce the burden of NAFLD, by adequate control of glucose and lipid metabolism, also reducing the risk of NASH progression, advanced fibrosis, and finally hepatocellular carcinoma. We extensively reviewed the literature, based either on registration studies, ad hoc randomized studies or real-world data, to define the effectiveness of anti-diabetic drugs in the treatment of NAFLD and prevention of hepatocellular carcinoma (HCC). Metformin provides the best evidence for decreased risk of HCC, pioglitazone was associated with decreased progression to fibrosis, glucagon-like peptide-1 receptor agonists offer a possible opportunity to reduce NAFLD progression coupled with a definite protection for cardiovascular outcomes, and sodium-glucose cotransporter-2 inhibitors are likely to reduce lipid burden, simultaneously reducing the risk of progressive renal and heart failure. For the latter two drug classes, the effects on NAFLD might largely explained by decreased body weight, in keeping with the beneficial effects of intensive lifestyle intervention.

创伤性颞下颌关节强直是指外伤引起的髁突与颞骨关节窝之间的纤维性或骨性融合,可导致患者张口受限、咀嚼困难,甚至阻塞性睡眠呼吸暂停低通气综合征。当儿童或青少年发生创伤性颞下颌关节强直,还会导致面部发育不对称、小颌畸形、咬合关系错乱等,严重影响患者身心健康。该病一旦发生则治疗困难、易复发,而且发病机制不清,一直是口腔颌面外科研究的热点和难点。本文结合国内外最新的研究进展,明确创伤性颞下颌关节强直的发病因素,如髁突的损伤、关节盘的损伤或移位、关节窝的损伤以及翼外肌的类牵张成骨作用;对“血肿机化”、“翼外肌类牵张成

慢性鼻-鼻窦炎（chronic rhinosinusitis，CRS）是耳鼻咽喉头颈外科常见病，病因和发病机制复杂。当前CRS的发病机制尚未完全明确，其发病主要与解剖结构、遗传及环境等多种因素有关。随着CRS基础及临床研究的不断深入，对其发病机制的认识越来越深刻。本文就CRS发病机制与免疫学机制、微生态、微小RNA和长链非编码RNA等相关的研究进展做一综述。
慢性鼻-鼻窦炎（chronic rhinosinusitis，CRS）是鼻窦黏膜的慢性炎症性疾病，症状主要为鼻塞、流脓涕、头面部胀痛及嗅觉减退和丧失等。近年来内镜鼻窦手术已成为CRS外科治疗的首选方法。虽然鼻窦手术方法较以往取得了长足发展，但临床实践发现鼻内镜手术仍无法彻底清除病灶，术后鼻腔黏膜粘连、水肿、愈合延迟等发生率高。因此临床上更加关注CRS的术后鼻腔处理。鼻腔填塞是术后较常见的治疗手段，

间充质干细胞(mesenchymal stemcells,MSCs)具有自我复制和多向分化能力,对间充质组织的发育和重建十分重要。骨组织损伤修复涉及各种细胞、分子的参与,骨量的恢复需要足够MSCs迁移到损伤部位发挥重建功能。目前已经发现损伤部位的局部炎症反应能募集MSCs,促进新骨形成。同时,MSCs迁移过程中生态位的改变也会影响其生物学性能,启动定向分化阶段。本文探讨了骨组织损伤修复过程中介导MSCs迁移的相关机制,包括炎症反应中的免疫细胞和趋化信号分子通过BMP/Smads等信号通路对骨修复阶段的调控
鼻息肉作为耳鼻咽喉科的常见疾病，人群发病率约为1%～4%。鼻息肉的组织学特征表现为血管内皮间隙增大，导致大量血浆蛋白漏出，组织呈现高度水肿的状态。外泌体作为一种纳米级囊泡，能运载多种蛋白质、mRNA、miRNA等物质，通过影响鼻腔菌群多样性，调节血管生成及通透性，分泌多种特定蛋白质等方式调控鼻息肉的发生发展。本文综述外泌体调控鼻息肉的发病机制，旨在为鼻息肉的临床诊治提供新思路。
嗅觉是人类重要的感觉功能之一。嗅觉功能障碍对人们的生活质量及精神健康影响巨大，尽管目前关于嗅觉功能障碍的治疗手段较多，但其疗效仍欠佳。嗅觉训练作为嗅觉功能障碍的主要治疗方法之一，具有简单易行的特点，同时依据嗅觉系统的神经可塑性作为理论基础，被证实在多种原因所致的嗅觉功能障碍的患者中具有一定疗效。嗅觉训练发展至今，传统的训练方法不断被改进、创新。为进一步了解嗅觉训练及其临床应用价值，本文就嗅觉训练的
