目的 通过年龄、性别等多方面研究各亚型注意缺陷多动障碍（ADHD）儿童的智力结构分布特征的临床研究，为ADHD的个体化干预提供科学依据。方法 实验组纳入ADHD儿童754例，其中注意缺陷型（ADHD-I）280例（37.13%）、多动-冲动型（ADHD-HI）212例（28.12%）、混合型（ADHD-C）262例（34.75%），按年龄分为三组：低龄组（6~8岁）、中龄组（9~11岁）及高龄组（12~14岁）；对照组为正常儿童412例，为同期选择的性别、年龄相匹配的儿童。选择采用韦氏智力评估等方法分别对两组儿童进行评估等，对评估结果进行比较和综合分析。结果 ADHD儿童的智力评估结果低于对照组（P＜0.01），且在言语智商方面表现更为明显，在各分测验中以A因子（言语理解）和C因子（记忆/注意集中）为主，而B因子（知觉组织能力）方面则无差异。ADHD-HI型及ADHD-C型的总智商及操作智商均高于ADHD-I型，ADHD-C型言语智商和A因子均高于ADHD-I型（P＜0.01），ADHD-HI型的智力水平最高，而ADHD-I型与ADHD-C型的智力水平差异无统计学意义（P＞0.05）。各年龄段ADHD儿童的智力发育均受到不同程度的影响，尤其是中龄组儿童及高龄组女童所受影响更明显；低、中龄组儿童的智力发育水平均高于高龄组儿童，提示ADHD儿童的智力损害随年龄增长而加重；同一年龄段ADHD女童的智力损害较男童更为严重。结论 本地区6~14岁ADHD儿童的智力水平较低，以言语智商低下更为明显，ADHD-HI型在3个亚型中智力损害最小，ADHD儿童的智力损害随年龄增长而加重，同一年龄段ADHD女童的智力损害较男童更为严重。

   Objective To investigate the distribution characteristics of intellectual structure in children with different subtypes of attention deficit hyperactivity disorder（ADHD）by age and gender，providing scientific basis for individualized treatment and intervention of ADHD．Methods The experimental group consisted of 754 children with ADHD，including 280 cases（37.13%）of inattentive type（ADHD-I），212 cases（28.12%）of hyperactivity impulsive type（ADHD-HI），and 262 cases（34.75%）of combined type（ADHD-C）．They were divided into three groups by age：young group（6-8 years old），middle group（9-11 years old），and older group（12-14 years old）．The control group consisted of 412 normal children with matched sex and age recruited during the same period and had similar sex ratio．The specific methods of Wechsler Intelligence Scale were mainly applied to evaluate normal children and children with ADHD，and the evaluation results were subjected to multidimensional analysis and comparison．Results The intelligence assessment results of ADHD children were significantly lower than those of the control group（P＜0.01），with a more pronounced performance in verbal intelligence．In various sub tests，factors A（verbal comprehension）and C（memory and attention concentration）were the main factors，while there was no difference in factor B（perceptual organization ability）．The ADHD-HI and ADHD-C types had higher total intelligence and operational intelligence than the ADHD-I type，and the ADHD-C type had higher verbal intelligence and factor A than the ADHD-I type（P＜0.01）．The intelligence level of the ADHD-HI type is the highest，while there is no statistically significant difference in intelligence level between the ADHD-I type and the ADHD-C type．The intellectual development of children in different age groups was affected to varying degrees，especially in the middle and older groups of girls．This study found that the intellectual development of children in the young and middle group was higher than that of children in the older group，indicating that the intellectual development of ADHD children will be increasingly damaged with age．At the same time，it was also found that ADHD girls in the same age group had more severe intellectual development impairment than boys．Conclusions The intelligence level of children with ADHD aged 6-14 in this region is relatively low，with verbal intelligence quotient being more pronounced．ADHD-HI has the smallest intellectual impairment among the three subtypes，and the intellectual development of ADHD children becomes more severe with age．ADHD girls in the same age group have more severe intellectual development impairment than boys．

       目的 探索Nrf2/HO-1通路是否参与远志皂苷元（远志）在脑出血体外细胞模型中对BV2小胶质细胞炎症反应的调控作用。方法 采用红细胞与BV2小鼠小胶质细胞共培养构建体外脑出血模型。分别给予远志单独处理、远志联合Nrf2抑制剂ML385处理，检测炎症因子水平。收集细胞上清制备条件培养基，用于培养SH-SY5Y人神经母细胞瘤细胞，并检测其铁死亡水平。结果 模型组BV2细胞炎症因子（IL-1β，IL-6，TNF-α）水平较对照组显著升高（P＜0.001）；高浓度远志（20 μM）可降低炎症因子水平，并上调Nrf2/HO-1通路蛋白表达，而ML385能逆转该作用。模型组条件培养基可诱导SH-SY5Y细胞铁死亡，而经远志处理的BV2细胞条件培养基则减轻该现象；ML385预处理可削弱远志对SH-SY5Y细胞的保护作用，远志组铁离子、丙二醛、转铁蛋白受体1水平低于远志联合ML385组（P＜0.05），铁转运蛋白、谷胱甘肽和谷胱甘肽过氧化物酶水平高于远志联合ML385组（P＜0.05）。结论 远志皂苷元通过激活Nrf2/HO-1通路抑制BV2小胶质细胞炎症反应，并在脑出血体外模型中发挥神经保护作用。

     Objective To investigate whether the Nrf2/HO1 signaling pathway is involved in the regulatory effect of tenuigenin（TEN）on the inflammatory response of BV2 microglial cells in an in vitro intracerebral hemorrhage（ICH）model．Methods An in vitro ICH model was established by coculturing BV2 murine microglial cells with red blood cells．Cells were treated with TEN alone or in combination with the Nrf2 inhibitor ML385，and the levels of inflammatory factors were measured．The conditioned medium collected from the cell supernatant was used to culture SHSY5Y human neuroblastoma cells，and ferroptosis levels were assessed．Results The levels of inflammatory factors（IL-1β，IL-6，TNF-α）in BV2 cells of the model group were significantly higher than those in the control group（P＜0.001）．High concentration of TEN（20 μM）could reduce the levels of inflammatory factors and up-regulate the expression of Nrf2/HO-1 pathway proteins，while ML385 could reverse this effect．The conditioned medium of the model group could induce ferroptosis in SH-SY5Y cells，while the conditioned medium of BV2 cells treated with TEN could alleviate this phenomenon．Pretreatment with ML385 could weaken the protective effect of TEN on SH-SY5Y cells．The levels of iron ions，malondialdehyde and transferrin receptor protein 1 in the TEN group were lower than those in the TEN combined with ML385 group（P＜0.05），while the levels of ferroportin glutathione and glutathione peroxidase 4 were higher than those in the TEN combined with ML385 group（P＜0.05）．Conclusions TEN inhibits the inflammatory response of BV2 microglial cells by activating the Nrf2/HO1 pathway and exerts a neuroprotective effect in the in vitro ICH model．

      目的 探讨不同体质指数（BMI）分组成年1型糖尿病（T1DM）患者的临床特征以及超重/肥胖与心血管代谢危险因素之间的关系。方法 纳入2015年6月至2022年6月在广州市第一人民医院内分泌代谢科住院的268例成人T1DM患者。分为超重肥胖组（BMI≥24.0 kg/m²，41例）、体质量正常组（18.5≤BMI＜24.0 kg/m²，155例）和体质量过低组（BMI＜18.5 kg/m²，72例）。比较三组人口学、人体测量及代谢指标的差异，采用多元线性回归分析BMI与估算肾小球滤过率（eGFR）的关联。结果 超重肥胖组患者的特征表现为年龄更大、病程更长、体脂肪量更高、腹部皮下脂肪面积更大、腰围、臀围更大、合并高血压比例更高、收缩压更高、高密度脂蛋白胆固醇更低、eGFR更低、糖化血红蛋白（HbA1c）更低。多元线性回归分析显示，校正年龄、性别、病程后，BMI与eGFR呈负相关（β=-2.050，P=0.012）；进一步校正HbA1c、血压、血脂后，该关联不再显著。结论 超重/肥胖成人T1DM患者存在多重代谢异常聚集，BMI与eGFR的负向关联可能主要与血糖、血压、血脂等代谢因素有关。

Objective To investigate the clinical characteristics of adult patients with type 1 diabetes mellitus（T1DM）in different body mass index（BMI）categories and the associations of overweight and obesity with cardiometabolic risk factors．Methods A total of 268 adult T1DM inpatients from Guangzhou First People’s Hospital were enrolled．Patients were divided into three groups：overweight/obese（BMI≥24.0 kg/m²，n=41），normal-weight（18.5≤BMI＜24.0 kg/m²，n=155），and underweight（BMI＜18.5 kg/m²，n=72）．Demographic characteristics，anthropometric measurements，and metabolic parameters were compared among the three groups．Multivariable linear regression analyses were performed to evaluate the association between BMI and estimated glomerular filtration rate（eGFR）．Results Patients in the overweight/obesity group were characterized by older age，longer diabetes duration，higher body fat mass，larger abdominal subcutaneous fat area，greater waist and hip circumferences，a higher prevalence of hypertension，higher systolic blood pressure，lower high-density lipoprotein cholesterol levels，lower eGFR，and lower glycated hemoglobin（HbA1c）levels．Multivariable linear regression analysis demonstrated that BMI was inversely associated with eGFR after adjustment for age，sex，and diabetes duration（β=-2.050，P=0.012）．However，this association was no longer significant after further adjustment for HbA1c，blood pressure，and lipid parameters．Conclusions Overweight/obese adult T1DM patients exhibit clustering of metabolic abnormalities．The negative association between BMI and eGFR may be primarily mediated by metabolic factors such as hyperglycemia，hypertension，and dyslipidemia．

       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．
