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．

弥漫性大B细胞淋巴瘤（DLBCL）是最常见的高度异质性非霍奇金淋巴瘤（NHL）,不同的疾病阶段或临床亚型预后不尽相同。放射治疗作为无交叉耐药的理想局部治疗技术,应用于DLBCL可有效改善患者预后。初治DLBCL通过放射治疗联合化学治疗、免疫治疗等综合治疗可使约60%~70%患者疾病缓解。对于不同预后影响因素,如年龄、肿瘤体积、淋巴结外侵犯等,联合放射治疗也可取得更佳疗效。在复发性/难治性DLBCL的治疗中,自体造血干细胞移植（ASCT）和嵌合抗原受体T细胞免疫治疗（CAR-T）是目前的研究热点,而放射治疗无论是作为ASCT与CAR-T术前的桥接治疗或失败后的挽救性治疗均有助改善患者预后。随着放射治疗技术的日益优化,放射治疗在综合治疗方案中扮演着越来越重要的角色。

Diffuse large B-cell lymphoma（DLBCL）is a highly heterogeneous type of non-Hodgkin lymphoma（NHL）and its prognosis is different for different disease stages or clinical subtypes．Radiation therapy（RT）is a local treatment technique that does not cause cross-resistance and can effectively improve the prognosis of patients with DLBCL．When combined with chemotherapy and immunotherapy,RT can alleviate the disease in more than 60% of patients．Furthermore,RT can achieve better results for different prognostic factors such as age,tumor volume and external nodal invasion．For treating relapsed / refractory DLBCL,autologous stem cell transplantation（ASCT）and chimeric antigen receptor T cell immunotherapy（CAR-T）are currently being researched,while RT can help as bridging therapy before ASCT and CAR-T or salvage therapy after failure．With the increasing optimization of technology,radiotherapy plays an increasingly important role in combined treatment options．

脊柱结核是脊柱感染性疾病中最为常见的类型。本文综述了脊柱结核外科治疗的现状及最新进展。在早期治疗阶段,规范化的抗结核药物治疗能够有效缓解疼痛,改善患者生活质量。但对于中后期,特别是椎旁脓肿较大,椎体骨质破坏较大而导致脊柱不稳定的患者,手术治疗往往是必要且必需的辅助手段,手术可以最大限度清除病变的椎间盘、椎体和脓肿,也应该最大限度保留健康的骨质。其主要原则包括病灶彻底清除、脊髓充分减压、脊柱稳定性重建等步骤。在手术治疗中,一期前路手术作为经典入路已经得到广泛应用,而单纯后路手术治疗也逐渐受到重视。近年来,随着微创手术技术的发展,其在脊柱结核治疗中的应用越来越广泛。微创手术的优势在于术中创伤更小、恢复更快,为患者带来了更好的治疗体验和临床效果。然而,对于手术的选择,临床医师需要综合考虑患者的个体差异性、临床表现及特征、影像学资料和手术适应证等多种因素,以确定最合适的治疗方案。只有充分考虑各种治疗手段的优劣,采取个性化、综合性的治疗方案,才能更好地提高患者的生活质量和治疗效果。

Spinal tuberculosis is the most common types of infectious diseases affecting the spine．This article reviews the current status and progress of surgical treatment for spinal tuberculosis．In the early and initial stages,standardized anti-tuberculosis drug therapy can effectively alleviate pain and improve patients' quality of life．However,for more complex cases in the middle and late stages,surgical treatment is needed,including thorough lesion clearance,adequate spinal cord decompression,and reconstruction of spinal stability．In surgical treatment,anterior approach surgery,as a classical method,has been widely applied,and posterior approach surgery alone has gradually gained attention．In recent years,with the development of minimally invasive surgical techniques,their application in the treatment of spinal tuberculosis has become increasingly widespread．The advantages of minimally invasive surgery lie in smaller intraoperative trauma and faster recovery,providing patients with better treatment experience and clinical outcomes．However,for the selection of surgery,clinicians need to consider multiple factors such as individual differences,clinical manifestations and characteristics,imaging data and surgical indications to determine the most suitable treatment plan．Only by fully considering the advantages and disadvantages of various treatment modalities and adopting personalized,comprehensive treatment plans can the quality of life and treatment outcomes of patients be effectively improved．

目的 探讨学生实验室安全知识盲区,以提高高校实验室安全管理工作的成效。方法 考试人数192人,共计235次考试,根据考试系统的统计分析结果,观察各题目错误率和各选项构成比;结合统计描述和χ²检验,探讨影响学生实验室安全考试成绩的原因和所存在的知识盲区。结果 41%的考生身份为在读硕士研究生,59%的考生为在读本科生,男生占48%,女生占52%,且比较不同身份的性别构成比,差异无统计学意义;题目被归纳分为“行为规范”“应急自救技能”和“事故防范能力”三大部分,比较“行为规范”和“应急自救技能”类题目的错误率,差异存在统计学意义（χ²=7.570,P=0.006）,“应急自救技能”类题目的错误率为3.14%,高于其余两类。结论 高校学生对应急自救技能类可能存在较多的知识盲区,应以之作为实验室安全管理工作关键控制点,加强应急自救技能培训可以极大地降低事故的严重程度。
