目的探讨幽门螺杆菌(HP)在肝硬化门脉高压性胃病发生、发展中的作用及临床意义,观察HP感染与食管静脉曲张程度的关系。方法随机选取新乡市中心医院肝硬化门脉高压性胃病患者76例及同期在同医院经胃镜和组织学检查确诊为无肝病病史中的慢性胃炎和消化性溃疡患者87例,进行分析。结果肝硬化门脉高压组HP感染率为30.3%,显著低于慢性胃炎组的76.5%(P<0.05)和消化性溃疡组的83.3%(P<0.05)。门脉高压性胃病患者慢性活动性胃炎HP感染率为53.6%,非活动性胃炎HP感染率为16.7%,两者差异有统计学意义(P<0.05)。HP感染率随食管静脉曲张程度的增加而下降(无食管静脉曲张者HP阳性率为58.3%,有食管静脉曲张者HP阳性率为21.2%,P<0.05。)结论肝硬化门脉高压性胃病是一种独特类型的胃病,其发生与发展与HP感染无显著相关性;HP感染不是门脉高压性胃病的主要致病因素,但HP感染和门脉高压性胃胃病黏膜的慢性活动性胃炎密切相关;肝硬化门脉高压影响HP感染率。

Meningeal lymphatic vessels form a relationship between the nervous system and periphery, which is relevant in both health and disease. Meningeal lymphatic vessels not only play a key role in the drainage of brain metabolites but also contribute to antigen delivery and immune cell activation. The advent of novel genomic technologies has enabled rapid progress in the characterization of myeloid and lymphoid cells and their interactions with meningeal lymphatic vessels within the central nervous system. In this review, we provide an overview of the multifaceted roles of meningeal lymphatic vessels within the context of the central nervous system immune network, highlighting recent discoveries on the immunological niche provided by meningeal lymphatic vessels. Furthermore, we delve into the mechanisms of crosstalk between meningeal lymphatic vessels and immune cells in the central nervous system under both homeostatic conditions and neurodegenerative diseases, discussing how these interactions shape the pathological outcomes. Regulation of meningeal lymphatic vessel function and structure can influence lymphatic drainage, cerebrospinal fluid-borne immune modulators, and immune cell populations in aging and neurodegenerative disorders, thereby playing a key role in shaping meningeal and brain parenchyma immunity.
