目的 调查国内养老机构痴呆照护服务现状,为今后国内进一步推进养老机构痴呆照护服务的发展提供可借鉴的依据。方法 2024年1月1日至3月31日以全国养老机构为研究对象, 采取两阶段分层抽样, 随机抽取国内15个省、自治区、直辖市的养老机构, 采用网络问卷调查方法对抽取的养老机构管理人员进行问卷调查。结果 共回收线上调查问卷443份, 经过去重和排除无效问卷, 最终得到的有效问卷为412份, 有效率为93%。调查发现有313家（76%）机构有收住痴呆患者, 养老床位规模为100~299张的养老机构占比最高。小规模的养老机构中,民办民营机构收住痴呆患者的比例高于公建公营机构。有181家机构设置了痴呆照护专区。床位数在300张以上的养老机构中设立痴呆照护专区的比例高于中、小规模的养老机构。结论 本调查较客观地呈现了我国养老机构痴呆照护服务开展的现状, 大规模的养老机构提供痴呆照护服务的能力更高, 设置痴呆照护专区的机构更能满足痴呆患者多层次、多样化的照护需求。目前国内仍存在专业化的痴呆照护服务供给不足、照护人员短缺等现象, 急需国家加强顶层设计, 促进行业健康发展。
Objective To explore the current situation of cognitive care services in nursing homes in China, and provide reference for further promoting the development of cognitive care services in nursing homes in China．Methods From January 1 to March 31, 2024, a two-stage stratified sampling was carried out to randomly select pension institutions in 15 provinces, autonomous regions and municipalities directly under the central government across the country, and a questionnaire survey was conducted on the nursing homes．Results A total of 443 online questionnaires were recovered in this survey, and 412 valid questionnaires were obtained after eliminating duplicated and invalid questionnaires, with an effective rate of 93%．In this survey, 76% of the institutions admitted the elderly with dementia, and the nursing homes with 100-299 beds accounted for the highest proportion．Among the small-scale nursing homes, the proportion of the elderly with dementia in private institutions is significantly greater than that in public institutions．There were 181 nursing homes with special cognitive care areas．The proportion of cognitive care area in nursing homes with more than 300 beds was significantly greater than that in medium and small scale nursing homes．Conclusions This survey Objectively presents the current situation of the development of cognitive care services in nursing homes in our country．Large-scale nursing homes have a higher capacity to provide cognitive care services．Nursing homes that set up special areas for cognitive care can better meet the multi-level and diversified care needs of the elderly with dementia．At present, there are still insufficient supply of professional cognitive care services and shortage of nursing personnel in China．It is urgent for the country to strengthen top-level design and promote the healthy development of the industry．
目的 探索α-突触核蛋白（α-Syn）干预对人单核细胞白血病细胞系（THP-1）巨噬细胞源性泡沫细胞的影响。方法 通过佛波酯（PMA）和氧化型低密度脂蛋白（ox-LDL）构建THP-1巨噬细胞源性泡沫细胞模型,使用不同浓度（33、66、100、133 nmol/L）α-Syn处理泡沫细胞,随后检测细胞胆固醇含量和炎症因子白细胞介素-1β（IL-1β）、白细胞介素-6（IL-6）及白细胞介素-8（IL-8）的mRNA表达以及核因子κB（NF-κB）和凝集素样氧化低密度脂蛋白受体-1（LOX-1）的蛋白表达变化。结果 高剂量（100和133 nmol/L）α-Syn处理可以减少THP-1巨噬细胞源性泡沫细胞内胆固醇的含量（P<0.05）,并且减少IL-1β、IL-6和IL-8的mRNA表达（P<0.05）。进一步发现（100 nmol/L和133 nmol/L）α-Syn可以降低THP-1巨噬细胞源性泡沫细胞p-NF-κB和LOX-1的蛋白表达（P<0.05）。结论 α-Syn可以降低THP-1源性巨噬细胞泡沫细胞胆固醇蓄积和炎症反应,可能是通过下调p-NF-κB和LOX-1蛋白表达。
Objective To explore the effects of α-synuclein（α-Syn）intervention on human monocytic leukemia cell（THP-1）macrophage-derived foam cells．Methods The THP-1 macrophage-derived foam cell model was constructed by phorbol 12-myristate 13-acetate（PMA）and oxidized low-density lipoprotein（ox-LDL）．Foam cells were treated with different concentrations（33, 66, 100, and 133 nmol/L）of α-Syn, and the cellular cholesterol contents, as well as the mRNA expression of IL-1β、IL-6 and IL-8 were detected．Subsequently,alternation in protein expression of NF-κB and LOX-1 was measured．Results High-dose（100 and 133nmol/L）α-Syn treatment significantly reduced the levels of intracellular cholesterol in THP-1-derived macrophage foam cells（P<0.05）and decreased the mRNA expression of IL-1β、IL-6 and IL-8（P<0.05）．It was further found that（100 nmol/L and 133 nmol/L）α-Syn decreased the protein expression of p-NF-κB and LOX-1 in THP-1 macrophage-derived foam cells（P<0.05）．Conclusions The results of the present study suggest that α-Syn reduces cholesterol accumulation and inflammatory response in THP-1-derived macrophage foam cells, possibly by down-regulating p-NF-κB and LOX-1 protein expression．

目的 初步探讨生长因子受体结合蛋白14（GRB14）在肺腺癌患者预后中的具体作用机制。方法 通过TIMER数据库、UALCAN数据库及GEPIA数据库，探讨GRB14 mRNA在肺腺癌及正常肺组织中的表达。运用免疫组织化学通过组织芯片（75例肺腺癌患者和75例癌旁组织）检测其蛋白表达水平，收集国外肿瘤研究团队上传至TCGA数据库229例肺腺癌患者的临床数据，分析评估GRB14在肺腺癌患者的表达及其临床特征及生存预后之间的关系。应用TIMER数据库对GRB14肺腺癌患者进行免疫浸润分析。String数据库探讨GRB14与其他蛋白之间是否存在相互作用。结果 TIMER数据库分析显示，相比正常组织，GRB14 mRNA在多种实体肿瘤和肺腺癌组织中高表达（P＜0.05）。使用UALCAN数据库和GEPIA数据库以正常样本为对照组，肺腺癌患者的GRB14的表达均增加（P＜0.01）。免疫组织化学检测组织芯片结果显示，GRB14蛋白在肺腺癌的表达高于正常肺组织（肺腺癌6.07±1.01 vs 癌旁组织4.80±1.22；P＜0.01）。TCGA数据库分析显示，肺腺癌患者中GRB14高表达组和低表达组的中位总生存期分别为（41.59±5.20）月和（88.67±16.69）月；结合TCGA数据库绘制ROC曲线，发现GRB14的表达对肺腺癌患者具有一定的诊断价值。单因素回归分析结果显示，肿瘤分期（Ⅲ-Ⅳ）（P＜0.01）、肿瘤原发灶的情况（T3-4）（P＜0.01）、淋巴结转移（N1-3）（P＜0.01）和GRB14表达（P＜0.01）是影响肺腺癌中位总生存期的因素；Cox多因素回归分析显示，淋巴结转移（N1-3）（P＜0.05）和GRB14表达（P＜0.01）是影响肺腺癌中位总生存时间的因素。TIMER数据库分析显示，GRB14 mRNA 表达与巨噬细胞（r=-0.164，P＜0.01）、中性粒细胞（r=-0.175，P＜0.01）和树突状细胞（r=-0.148，P＜0.01）具有相关性。通过String数据库分析发现与GRB14相互作用的蛋白质包括EGFR、HRAS、FGFR1、INSR、CNGA1、COBLL1、LYPLAL1、TNKS2、TNKS、PRKCZ。结论 GRB14表达增加与肺腺癌患者预后不良相关。
Objective To assess the specific mechanism of growth factor receptor-bound protein 14（GRB14）in the prognosis of lung adenocarcinoma（LUAD）patients．Methods The expression of GRB14 mRNA in LUAD and normal lung tissue was explored using TIMER database，UALCAN database，and GEPIA database．The expression of GRB14 protein was examined by immunohistochemistry using a tissue microarray．Then，the associations of GRB14 expression with clinicopathological features and clinical outcomes of LUAD were validated by analyzing TCGA database at the mRNA level and statistically evaluating the results．TIMER database was used to analyze immune infiltration of GRB14 in LUAD．Protein-protein interaction of GRB14 were analyzed using the String database．Results Using the TIMER database，we found that GRB14 mRNA was highly expressed in various solid tumors and LUAD tissues compared to normal tissues（P＜0.05）．Comparing with the normal group，the expression of GRB14 was increased in LUAD（P＜0.01）via using UALCAN database and GEPIA database．The expression level of GRB14 protein in the LUAD tissues was significantly higher than that in the noncancerous LUAD tissues（LUAD［6.07±1.01］ vs benign，［4.80±1.22］；P＜0.01）in tissue microarray ．Median overall survival in the high and low GRB14 expression groups in LUAD was（41.59±5.2）and（88.67±16.69）months respectively．We plotted the ROC curves of 3-year survival rate and 5-year survival rate which again suggested that the model had good predictive performance．Univariate analysis revealed that individual cancer stages（Ⅲ-IV）（P＜0.01），tumor（T3-4）（P＜0.01），lymph node metastasis（N1-3）（P＜0.05）and GRB14 expression（P＜0.01）were risk factors affecting the median overall survival time of LUAD．According to Cox multiple regression analysis，we found that lymph node metastasis（N1-3）（P＜0.05）and GRB14 expression（P＜0.01）were risk factors affecting the median overall survival time of LUAD．Using TIMER database analysis，the mRNA level of GRB14 was significantly correlated with macrophages（r=-0.164，P＜0.01），neutrophils（r=-0.175，P＜0.01）and dendritic cells（r=-0.148，P＜0.01）．Through analysis of the String database，it was found that proteins that interacted with GRB14 including EGFR，HRAS，FGFR1，INSR，CNGA1，COBLL1，LYPLAL1，TNKS2，TNKS，PRKCZ．Conclusions The results of the present study suggest that GRB14 may efficiently predict poor survival in LUAD patients．
