慢性炎症是心血管疾病的常见发病机制,它主要通过损伤内皮细胞、氧化应激和刺激血栓形成影响疾病发展。全身免疫炎症指数(SII)作为一种新型炎症指标,最早用于肿瘤患者的预后评估,现已在多学科领域广泛使用,它由中性粒细胞、血小板、淋巴细胞计算得到,更加全面地反映机体炎症状态。SII已经在多项研究中被证实具有良好的预测价值,该文对SII的优势和在心血管疾病的临床研究进展进行综述,为研究的进一步开展提供参考。
Chronic inflammation is a common pathogenesis of cardiovascular disease,which mainly affects disease progression by damaging endothelial cells,oxidative stress and stimulating thrombosis.As a new type of inflammatory index,the systemic immune inflammatory index(SII)was first used to evaluate the prognosis of cancer patients,and has been widely used in multidisciplinary fields.SII has been confirmed to have good predictive value in a number of studies,and this article reviews the advantages of SII and the progress of clinical research in cardiovascular diseases,so as to provide reference for further research development.

目的 从炎症反应和肠道屏障两个方面探究五味苦参肠溶胶囊对葡聚糖硫酸钠(DSS)诱导的小鼠结肠炎的治疗作用。方法 6~8周龄雄性BALB/c小鼠被随机分为3组,分别为正常组、急性肠炎模型组和五味苦参组。急性肠炎模型组和五味苦参组小鼠予含有3% DSS的饮用水1周诱导急性结肠炎,其后急性肠炎模型组予PBS灌肠,五味苦参组予五味苦参肠溶胶囊制备为灌肠液灌肠。每天称量小鼠体质量,观察大便性状及血便情况,第8天处死小鼠,取结肠组织检测炎症细胞因子和肠屏障因子。结果 与正常组相比,急性肠炎模型组肠道炎症明显,五味苦参组有效缓解肠道炎症和有利于肠上皮屏障修复。表现为五味苦参灌肠液有效缓解小鼠体质量下降,具有较低的DAI评分,有较好的组织学表现,其结肠组织IL-1β,IL-6和TNF-α的相对表达下降,Occludin和ZO-1的相对表达增加(P<0.05)。结论 五味苦参肠溶胶囊制备的灌肠液可减轻DSS诱导的小鼠急性结肠炎。
Objective To explore the therapeutic effect of five-flavor sophora flavescens enteric-coated capsules(FSEC)on dextran sulphate sodium(DSS)-induced colitis in mice from inflammatory response and intestinal barrier.Methods Male BALB/c mice aged 6-8 weeks were randomly divided into three groups,namely normal group,acute colitis group and FSEC group.The mice in acute colitis group and FSEC group were given drinking water containing 3% DSS for one week to induce acute colitis,and then they were given PBS enema or FSEC enema respectively.The mice were administered daily,including weight loss,the stool properties and bloody feces.The mice were sacrificed on the 8th day,and the colon tissue was collected to detect inflammatory cytokines and intestinal barrier cytokines.Results Compared with the normal group,the intestinal inflammation in the acute colitis group was obvious,however the FSEC effectively relieved intestinal inflammation and facilitated the intestinal epithelial barrier repair.It showed that FSEC enema effectively relieved weight loss and had a lower disease activity index score.In addition,FSEC enema group had better histological appearance.Compared to acute colitis group,the relative expression of IL-1β,IL-6 and TNF-α in colon tissue decreased,and the relative expression of Occludin and ZO-1 significantly increased in FSEC group(P<0.05).Conclusions FSEC enema can alleviate DSS-induced acute colitis in mice.

高压氧治疗是在高于当地压力的环境下,吸入高于当地大气氧浓度的氧来治疗疾病的方法,主要用于缺氧缺血性疾病或与缺氧缺血有关的疾病的治疗。炎症作为机体对刺激的一种防御机制,是感染、损伤、中毒等疾病共同的病理生理基础,在疾病的发生发展中扮演重要角色。高压氧与炎症的关系密切,围绕高压氧与炎症调节相关的研究进行综述,对深入认识高压氧的作用机制具有重要的意义。
Hyperbaric oxygen therapy is the treatment of diseases by inhaling oxygen at a concentration higher than the local atmospheric oxygen concentration in an environment that higher than the local pressure.It is mainly used in the treatment of hypoxic-ischemic diseases or diseases related to hypoxia-ischemia.As a defense mechanism against stimulation,inflammation is the common pathophysiological basis of infection,injury,poisoning and other diseases,which plays an important role in the occurrence and development of diseases.Hyperbaric oxygen is closely related to inflammation.The review on hyperbaric oxygen and inflammation regulation is of great significance to further understand the mechanism of hyperbaric oxygen.
