目的 研究靶向NKG2A抑制剂抗头颈部鳞状细胞癌（HNSCC）的作用。方法 应用GEO和TCGA数据库分析NKG2A及其配体HLA-E单细胞表达情况、与患者预后以及免疫微环境的相关性。构建HNSCC皮下抑制瘤模型,流式细胞技术检测化学治疗（化疗）对免疫检测点NKG2A表达的影响。动物实验验证NKG2A抑制剂以及NKG2A抑制剂联合多西他赛化疗的抗肿瘤作用。结果 NKG2A（KLRC1）主要表达在NK细胞,少量表达在T淋巴细胞。HNSCC肿瘤高表达NKG2A/HLA-E（P<0.01）,与患者不良预后密切相关;肿瘤微环境中NKG2A/HLA-E与多个免疫细胞浸润以及免疫检测点表达密切相关（P<0.01）。动物实验显示化疗能上调T、B淋巴细胞表达免疫检查点NKG2A的表达水平（P<0.01）;化疗的基础上联合NKG2A抑制剂能更有效地介导抗肿瘤作用（P=0.013）。结论 化疗基础上联合NKG2A抑制剂能更有效地介导抗肿瘤作用,为探索HNSCC临床新策略提供实验和理论基础。

Objective To investigate the anti-tumor effects of NKG2A inhibitor on head and neck squamous cell carcinoma（HNSCC）．Methods The single-cell expression of NKG2A ,its ligand HLA-E and their correlations with patient prognosis and immune microenvironment were analyzed in GEO and TCGA databases．The subcutaneous tumor model of HNSCC was constructed,and the effects of chemotherapy on the expression of NKG2A on T and B lymphocytes were detected by flow cytometry．Animal experiments were used to confirmed the anti-tumor effects of NKG2A inhibitor and NKG2A inhibitors combined with docetaxel．Results NKG2A（KLRC1）was mainly expressed in NK cells,and a small amount was expressed in T lymphocytes．The high expression of NKG2A/HLA-E in HNSCC tumors（P<0.01）were closely related to poor prognosis．NKG2A/HLA-E in tumor microenvironment were closely related to the infiltration of multiple immune cells and the expression of immune checkpoints（P<0.01）．Animal experiments showed that chemotherapy could up-regulate the expression of NKG2A in T and B lymphocytes（P<0.01）．Chemotherapy in combination with NKG2A inhibitor could mediate more effective antitumor effects in HNSCC（P=0.013）．Conclusions Combined with NKG2A inhibitor on the basis of chemotherapy can mediate more effective anti-tumor effects,and this study may provide experimental and theoretical basis for exploring new clinical strategies of HNSCC．

目的 探讨多梳蛋白SUZ12对肝细胞肝癌（HCC）细胞增殖、血管生成拟态形成和人脐静脉内皮细胞（HUVECs）血管生成的影响。方法 分别利用MTT比色法及体外血管生成实验检测SUZ12表达水平改变对HCC细胞SMMC-7721、Hep3B增殖、血管生成拟态形成和HUVECs血管生成的影响。结果 MTT结果显示,在HCC细胞中分别敲低或过表达SUZ12均对HCC细胞的增殖能力无明显影响。将SUZ12低表达HCC细胞与HUVECs共培养后,HCC细胞的血管生成拟态管样结构形成增多。此外,将SUZ12敲低组HCC细胞的培养上清用于培养HUVECs后,HUVECs的血管生成拟态管样结构形成也明显增多。结论 SUZ12对HCC细胞的增殖无影响,其在HCC中可抑制HCC细胞和HUVECs的血管生成拟态管样结构形成。上述结果提示SUZ12可能通过调控HCC细胞及HUVECs的血管生成发挥抑癌作用。

Objective To investigate the effects of SUZ12 on cell proliferation of hepatocellular carcinoma（HCC）,vasculogenic mimicry formation and human umbilical vein endothelial cells（HUVECs）angiogenesis．Methods MTT assay was performed to detect the proliferation of SMMC-7721 and Hep3B cells．The effects of SUZ12 on the angiogenesis of HCC cells and HUVECs cells were studied by in vitro angiogenesis experiment．Results The result of MTT assay showed that SUZ12 knockdown or overexpression in HCC cells had no significant effect on the proliferation of HCC cells．We found that when HCC cells with low SUZ12 expression were co-cultured with HUVECs cells,the formation of vasculogenic mimicry tubular structures in HCC cells increased．In addition,we also found that after the culture supernatant of HCC cells in the SUZ12 knockdown group was used to culture HUVECs cells,the formation of vasculogenic mimicry tubular structures in HUVECs cells also increased significantly．Conclusions SUZ12 has no effect on the proliferation of HCC cells,but it can inhibit the formation of vasculogenic mimicry tubular structures in HCC cells and HUVECs cells．These results suggest that SUZ12 plays a role in cancer inhibition by regulating the angiogenesis of HCC cells and HUVECs cells．

Objective To investigate the prognostic value of serum syndecan-1（SCD-1）and soluble vascular endothelial growth factor receptor-2（sVEGFR-2）expression levels in elderly patients with chronic heart failure. Methods A total of 110 elderly patients with chronic heart failure admitted to our hospital were selected,with a time interval of January 2023 to March 2024．Serum SCD-1 and sVEGFR-2 levels were detected and follow-up investigations were conducted to understand their re hospitalization and cardiogenic death due to heart failure．Multiple logistic regression analysis was used to explore the prognostic factors affecting elderly patients with chronic heart failure. Results According to logistic retrospective analysis,heart function grading（OR=3.433,95%CI：0.934-6.431）,elevated B-type brain natriuretic peptide（OR=2.462,95%CI：0.861-4.765）,elevated serum SCD-1（OR=3.795,95%CI：0.972-6.894）,and elevated serum sVEGFR-2（OR=3.842,95%CI：0.942-6.912）were important factors affecting the poor prognosis of elderly patients with chronic heart failure,with differences P<0.05．The area under the curve of combined serum SCD-1 and sVEGFR-2 was 0.962,and the area under the curve of B-type brain peptide sodium was 0.844,which was significantly higher than that of a single SCD-1 curve of 0.658 and sVEGFR-2 curve of 0.712,with a difference of P<0.05. Conclusions Research has confirmed that the prognosis of elderly patients with chronic heart failure is not satisfied,and their serum SCD-1 and sVEGFR-2 monitoring levels are abnormally elevated,which is related to the poor prognosis of elderly patients with chronic heart failure．It can be regarded as the main biomarker for defining the prognosis of elderly patients with chronic heart failure．

随着糖尿病发病率不断攀升,人们逐渐聚焦于糖尿病合并骨质疏松。围绕此疾病,国内外学者开展了广泛而深入的研究,临床实践聚焦于两点：糖尿病的精准治疗和骨质疏松的有效干预。在确保血糖稳定的基础上,致力于抑制骨吸收、促进骨形成。在此治疗理念指导下,临床医生应当更加全面了解血糖管理与抗骨质疏松药物的作用机制并合理应用,更大程度改善患者的临床症状及预后。然而,药物作用机制复杂,联合应用存在潜在药物相互作用问题。未来研究方向包括探索更安全有效的联合治疗方案,更加精确化地治疗以提高临床疗效。文章分析了降糖药物及抗骨质疏松药物对疾病的疗效,并展望未来的研究方向,旨在为临床实践提供更为深刻与全面的指导。

As the incidence of diabetes mellitus continues to rise,people are also gradually focusing on diabetes mellitus combined with osteoporosis,which puts patients at a higher risk of fragility fracture．Scholars at home and abroad have conducted extensive and in-depth research around this condition,and clinical practice has focused on two points：first,the precise treatment of diabetes,and second,the effective intervention of osteoporosis．On the basis of ensuring blood glucose stabilization,we are committed to inhibiting bone resorption and promoting bone formation．Under the guidance of this therapeutic concept,we should have a more comprehensive understanding of the mechanism of action of blood glucose management and anti-osteoporosis drugs and apply them rationally,aiming to improve the clinical symptoms and prognosis of patients to a greater extent through dual intervention． However,the mechanism of action of different drugs is complex,and there are potential drug-drug interactions and safety issues associated with their combined use．Future research directions should include exploring safer and more effective combination therapies,developing novel drugs,and more precise and individualized treatments to improve clinical efficacy．This article analyzes the efficacy of glucose-lowering drugs and anti-osteoporosis drugs on the disease and looks forward to future research directions,aiming to provide more profound and comprehensive guidance for clinical practice．

自发性脑出血（SICH）是脑卒中的一种常见形式,其预后通常较差,因此早期评估和调节患者出血后的免疫状态至关重要。免疫检查点是评估T淋巴细胞活跃性和增殖状态的关键指标,监测这些检查点有助于预测脑出血患者的预后。程序性死亡蛋白1（PD-1）和细胞分化抗原28（CD28）作为两个典型的免疫检查点,它们在脑出血预后评估中的应用正逐渐成为研究的热点。该文综述了脑出血后机体免疫状态的变化,以及PD-1和CD28在脑出血后评估和治疗中的研究进展。

Spontaneous intracerebral hemorrhage（SICH）is a common cause of stroke,with specific outcomes often being poor．Therefore,early assessment and modulation of the immune status after hemorrhage are of critical importance．Immune checkpoints serve as key indicators for assessing the activation and proliferation of T cells,and monitoring these checkpoints can help to predict the outcomes of patients with intracerebral hemorrhage．PD-1（programmed death 1）and CD28（Cluster of Differentiation 28）are two representative immune checkpoints,and their use in prognostic assessment after intracerebral hemorrhage is becoming a focus of research．This article reviews the changes in the immune state of the body after intracerebral hemorrhage,as well as the research progress on the use of PD-1 and CD28 in the evaluation and treatment following intracerebral hemorrhage．
