目的 构建首发脑出血患者并发卒中相关性肺炎的风险预测模型并验证模型的预测性能。方法 回顾性分析2012年1月—2022年12月广州市第一人民医院治的419例首发脑出血患者的临床资料，按照7︰3比例随机化分为训练列（293例）和验证队列（126例）。统计基于开发队列数据，采用Logistic回归模型分析首发脑出血患者并发卒中相关性肺炎的影响因素，并构建风险预测模型。基于开发队列和验证队列数据，采用校准曲线、受试者操作特征（ROC）曲线下面积和决策曲线分析模型的预测性能。结果 419例首发脑出血患者中有113例发生卒中相关性肺炎，发生率为26.97%。美国国立卫生研究院卒中量表（NIHSS）评分、吞咽困难、初始血肿体积、中性粒细胞百分比与白蛋白比值（NPAR）、中性粒细胞计数与淋巴细胞计数比值（NLR）、手术治疗、气管插管、留置胃管均是首发脑出血患者并发卒中相关性肺炎的影响因素（P＜0.05）。基于上述影响因素构建了首发脑出血患者并发卒中相关性肺炎的风险预警模型，校准曲线显示模型在开发队列和验证队列中预测卒中相关性肺炎发生率均与实际发生率相近；ROC曲线显示此模型在开发队列、验证队列中预测的曲线下面积分别为0.906（95%CI：0.867~0.937）、0.884（95%CI：0.815~0.934）；决策曲线分析显示当开发队列阈概率在3%~80%内、验证队列阈概率在2%~76%内使用此模型干预比全/无干预更有临床价值。结论 基于NIHSS评分、吞咽困难、初始血肿体积、NPAR、NLR、手术治疗、气管插管、留置胃管构建的首发脑出血患者并发卒中相关性肺炎的风险预测模型具有良好预测性能和临床应用价值。

      Objective To construct a risk prediction model for stroke associated pneumonia in patients with initial cerebral hemorrhage（ICH）and validate the predictive performance of the model．Methods A retrospective analysis was conducted on the clinical data of 419 patients with ICH admitted to our hospital from January 2012 to December 2022．They were randomly divided into a development cohort（293 cases）and a validation cohort（126 cases）according to a 7∶3 ratio．The Logistic regression model was used to analyze the influencing factors of stroke related pneumonia in patients with ICH based on the development cohort data，and a risk prediction model was constructed．Based on the development cohort data and validation cohort data，the predictive performance of the model was analyzed using calibration curves，receiver operating characteristic（ROC）curve，and decision curve analysis．Results Among 419 patients，113 developed stroke associated pneumonia，with a rate of 26.97%．The National Institutes of Health Stroke Scale（NIHSS）score，swallowing difficulties，initial hematoma volume，neutrophil percentage to albumin ratio（NPAR），neutrophil count to lymphocyte count ratio（NLR），surgical treatment，endotracheal intubation，and indwelling gastric tube were all independent influencing factors for stroke associated pneumonia in patients with ICH（P＜0.05）．Based on the above influencing factors，a risk prediction model for stroke associated pneumonia in patients with ICH was constructed．The calibration curve showed that the predicted incidence of stroke associated pneumonia by the model in both the development and validation cohorts was close to the actual incidence．The ROC curve showed that the predicted area under the curve for this model in the development cohort and validation cohort was 0.906（95%CI：0.867-0.937）and 0.884（95%CI：0.815-0.934），respectively．The decision curve analysis showed that when the threshold probability of the development cohort was between 3%-80%，and the threshold probability of the validation cohort was between 2%-76%，the intervention using this model was more clinically valuable than all/no intervention．

Conclusions The risk prediction model for stroke associated pneumonia in patients with ICH based on NIHSS score，swallowing difficulties，initial hematoma volume，NPAR，NLR，surgical treatment，tracheal intubation，and indwelling gastric tube has good predictive performance and clinical application value．

    Autosomal dominant polycystic kidney disease（ADPKD）stands as a leading cause of inherited renal failure，with current therapeutic strategies lacking effective means to reverse disease progression．Stem cell therapy，owing to its potential in tissue repair and immunomodulation，has emerged as a focal point of research．This review systematically elucidates the mechanisms by which hematopoietic stem cells（HSCs）intervene in ADPKD pathology through paracrine effects，metabolic reprogramming，and immune regulation．Furthermore，it summarizes clinical translational evidence of HSCs in both acute kidney injury and chronic kidney disease．This article also comparatively analyzes the unique advantages and challenges of mesenchymal stem cells（MSCs）and induced pluripotent stem cells（iPSCs）in the context of ADPKD treatment，thereby providing theoretical support for the development of multimodal stem cell therapies．

       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．
