目的 探究肺泡灌洗液靶向高通量测序（tNGS）在鹦鹉热衣原体肺炎中应用效果。方法 选取2021年5月—2025年3月我院收治的35例鹦鹉热衣原体肺炎患者进行研究，患者均接受肺泡灌洗液tNGS检测、肺泡灌洗液常规病原检测，以病原学为金标准，分析肺泡灌洗液tNGS对鹦鹉热衣原体肺炎的诊断效能。结果 金标准对鹦鹉热衣原体阳性检出35例，检出率100.00%，肺泡灌洗液tNGS阳性检出率高于传统病原检测，检测结果回报耗时短于肺泡灌洗液传统病原检测（P＜0.05）。结论 鹦鹉热衣原体肺炎临床症状缺乏特异性，容易转为重症肺炎，肺泡灌洗液tNGS可提高鹦鹉热衣原体肺炎检出率且结果回报较快，采用四环素类、喹诺酮类抗生素有助于改善患者预后。

     Objective To investigate the application effect of targeted next-generation sequencing（tNGS）of bronchoalveolar lavage fluid（BALF）in Chlamydia psittaci pneumonia．Methods Thirty-five patients with Chlamydia psittaci pneumonia admitted to our hospital from May 2021 to March 2025 were selected for the study．All patients underwent BALF tNGS and conventional BALF pathogen detection．With etiology as the gold standard，the diagnostic efficacy of BALF tNGS for Chlamydia psittaci pneumonia was analyzed．Results The gold standard detected 35 cases of Chlamydia psittaci positive，with a detection rate of 100.00%．The positive detection rate of tNGS in alveolar lavage fluid was higher than that of traditional pathogen detection，and the results report time of tNGS was shorter than that of traditional pathogen detection（P＜0.05）．Conclusions Chlamydia psittaci pneumonia lacks specificity in clinical symptoms and is easy to turn into severe pneumonia，bronchoalveolar lavage fluid tNGS can improve the detection rate of Chlamydia psittaci pneumonia and the results return quickly，and the use of tetracyclines and quinolones antibiotics can help improve the prognosis of patients．

       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．

       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．

[Abstract]Objective:To explore the impact of refined intraoperative instrument management by operating room nurses on the efficiency and safety of HVR surgery.Methods:The study subjects included 110 patients with VHD who underwent HVR treatment at our hospital from June 2024 to May 2026, along with 22 instrument nurses who participated in the surgeries synchronously. Using the random number table method, the enrolled patients and nurses were divided into a control group (55 patients, 11 nurses) and an experimental group (55 patients, 11 nurses). Nurses in the conventional group implemented routine instrument management during surgery, while nurses in the experimental group implemented zoned and refined instrument management during surgery. The surgical efficiency, perioperative safety events of the two groups of patients, as well as the work efficiency and intraoperative instrument management of the surgeries participated by the nurses in the two groups were compared.Results:Under different instrument management modes, the aortic occlusion time, extracorporeal circulation time, intraoperative non-essential waiting time, and total surgical time of patients in the experimental group were all lower than the control group (t=8.817，5.730，20.609，9.632; P<0.05). The incidence of perioperative safety events in the experimental group was 9.09% (5/55) lower than that in the control group 25.45% (14/55) (x2=5.153; P<0.05). The instrument placement time, instrument delivery response time, number of surgical interruptions, instrument sorting time, and instrument handover time of nurses in the experimental group were lower than those in the control group (t=3.347，6.505，5.971，3.795，5.838; P<0.05). The error rate of nurses in the experimental group was lower than the control group (x2=5.238; P < 0.05).Conclusion:Refined intraoperative zone-specific instrument management by instrument nurses enhances surgical efficiency for HVR patients and reduces the risk of perioperative safety incidents, thereby positively impacting the quality of instrument care provided by nurses and preventing instrument-related adverse events.

Abstract Objective To investigate the application effect of nutrition management based on the E-Coach health management model combined with active cycle of breathing technique (ACBT) in patients undergoing chemotherapy for non-small cell lung cancer (NSCLC). Methods A total of 98 NSCLC patients receiving chemotherapy in our hospital from June 2023 to August 2025 were selected and randomly divided into a combination group and a conventional group using a random number table method, with 49 cases in each group. The conventional group received routine intervention, while the combination group received nutrition management based on the E-Coach health management model combined with ACBT in addition to the routine intervention. The nutritional status, lung function, exercise endurance, quality of life, and incidence of malnutrition were compared between the two groups before and after the intervention. Results After 12 weeks of intervention, BMI, ALB, PA, and Hb in both groups increased compared with baseline, and the levels in the combination group were higher than those in the conventional group (P<0.05). The FVC, FEV1, MVV, and 6MWT in the combination group were significantly higher than those in the conventional group (P<0.05). There was no statistically significant difference in 6MWT between the two groups before intervention (P>0.05); after 4, 6, 8, and 12 weeks of intervention, the 6MWT in both groups increased compared with baseline, and the walking distance in the combination group was significantly longer than that in the conventional group (P<0.05). After 12 weeks of intervention, the scores of physical function, social/family function, emotional function, and functional well-being in both groups increased compared with baseline, and the scores in the combination group were higher than those in the conventional group (P<0.05). Conclusion Nutrition management based on the E-Coach health management model combined with ACBT can effectively improve the nutritional status and lung function of NSCLC patients undergoing chemotherapy, and enhance their quality of life and exercise endurance.

心肌纤维化是心力衰竭等心血管疾病演化过程中的关键性病理改变，该病的进展机制依赖巨噬细胞与成纤维细胞的相互调控。现有现代医学研究证实巨噬细胞可凭借M1、M2表型极化行为介导炎症反应与组织修复过程，成纤维细胞能够分化形成肌成纤维细胞并推动细胞外基质异常沉积，两类细胞可依托TGF-β/Smad、CSF-1/CSF-1R等信号通路构建相互调控的作用网络并介导心肌纤维化恶化。中医痰瘀互结病机理论指出痰浊与瘀血可相互滋生、交织阻滞，是各类慢性迁延性疾病的关键发病基础。本文以中医痰瘀互结理论为研究切入点，剖析该病机理论与巨噬细胞、成纤维细胞交互作用的内在关联，整合现代医学关于两种细胞交互作用的现有研究成果，深入分析细胞互作在心肌纤维化发病过程中的协同机制与病理关联，旨在为心肌纤维化的中西医协同防治提供理论依据，为相关动物实验及临床应用研究筑牢研究基础。

Myocardial fibrosis is a key pathological change in the progression of cardiovascular diseases such as heart failure. The progression mechanism of this disease relies on the reciprocal regulation between macrophages and fibroblasts. Current modern medical research has confirmed that macrophages can mediate inflammatory responses and tissue repair processes through M1 and M2 phenotypic polarization behaviors, and fibroblasts can differentiate into myofibroblasts and promote abnormal extracellular matrix deposition. The two types of cells can construct a reciprocal regulatory network through signaling pathways such as TGF-β/Smad and CSF-1/CSF-1R, thereby mediating the deterioration of myocardial fibrosis. The theory of phlegm and blood stasis intermingling in traditional Chinese medicine suggests that phlegm turbidity and blood stasis can mutually generate and interweave to cause obstruction, serving as a key pathological basis for various chronic and persistent diseases. This article takes the traditional Chinese medicine theory of phlegmblood stasis intermingling as a research entry point, analyzes the intrinsic relationship between this pathological theory and the interaction of macrophages and fibroblasts, integrates existing modern medical research findings on the interaction between the two cell types, and deeply analyzes the synergistic mechanisms and pathological correlations of cellcell interactions in the pathogenesis of myocardial fibrosis. The aim is to provide a theoretical basis for the integrated traditional Chinese and Western medicine prevention and treatment of myocardial fibrosis, and also to lay a solid research foundation for related animal experiments and clinical application studies.

【摘要】 目的 探讨基于峰值呼气流速（peak expiratory flow rate，PEFR）的呼吸性肌肉力量减低对I-IIIA期非小细胞肺癌（non-small cell lung cancer，NSCLC）患者术后预后的影响。方法 回顾性分析我院2020年1月-2025年11月接受根治性手术切除的I-IIIA期NSCLC患者临床及影像资料，包括基于肺功能的PEFR（呼吸性肌肉力量指标）及胸部CT的胸肌质量指数（pectoralis muscle index, PMI）。分别采用Jonckheere-Terpstra检验、Spearman’s相关分析比较PEFR与PMI随年龄的变化规律及二者的相关性。低PEFR定义为小于PEFR的性别特异性下四分位数，进一步采用单、多因素Cox回归分析探讨PEFR及PMI对NSCLC患者术后结局的影响。结果 共纳入102例患者，中位年龄62岁（53-67岁），男性65例（63.7%），低低PEFR组24例（23.5%）。低PEFR组在年龄、FEVI、DLCO、FEV1/FVC、FVC、血清白蛋白及随访时间等方面均与正常组间存在显著差异（P＜0.05）。在男、女性患者中，PEFR均表现为随年龄增长逐渐下降的趋势；且与PMI具有较好的相关性（r=0.25，P=0.001）。单因素及多因素Cox回归分析显示，低PEFR是影响NSCLC患者术后无进展生存期（progression free survival, PFS）的独立危险因素（HR=1.57，95%CI：1.03-2.39；P=0.036）结论 呼吸性肌肉力量减低是NSCLC患者术后PFS的独立危险因素，有望成为NSCLC术后复发的早期生物学标志物。

【Abstract】 Objective To investigate the impact of reduced respiratory muscle strength, assessed by peak expiratory flow rate (PEFR), on postoperative outcomes in patients with stage I-IIIA non-small cell lung cancer (NSCLC). Methods Clinical and imaging data of patients with stage I-IIIA NSCLC who underwent radical resection at our hospital from January 2020 to November 2025 were retrospectively analyzed, including PEFR (an indicator of respiratory muscle strength) based on pulmonary function tests and the pectoralis muscle index (PMI) derived from chest CT. The Jonckheere-Terpstra test and Spearman’s correlation analysis were used to evaluate age-related changes in PEFR and PMI and their correlation, respectively. Low PEFR was defined as values below the sex-specific lower quartile of PEFR. Univariate and multivariate Cox regression analyses were performed to assess the impact of PEFR and PMI on postoperative prognosis in NSCLC patients.Results A total of 102 patients were enrolled, with a median age of 62 years (range 53-67 years); 65 patients (63.7%) were male, and 24 (23.5%) were classified into the low PEFR group. The low PEFR group showed significant differences from the normal PEFR group in age, FEV1, DLCO, FEV1/FVC, FVC, serum albumin, and follow-up duration (all P < 0.05). In both male and female patients, PEFR progressively decreased with age and was positively correlated with PMI (r = 0.25, P = 0.001). Univariate and multivariate Cox regression analyses identified low PEFR as an independent risk factor for postoperative progression-free survival (PFS) in NSCLC patients (HR = 1.57, 95% CI: 1.03–2.39; P = 0.036).Conclusion Reduced respiratory muscle strength is an independent risk factor for postoperative PFS in NSCLC patients and may serve as an early biomarker for postoperative recurrence.

目的 探讨动态社交行为技巧练习联合生物反馈对学龄注意缺陷多动障碍（ADHD）患儿临床症状和社会功能的影响。方法 回顾性选取我院2021年1月~2024年3月收治的81例学龄ADHD患儿作为研究对象，按照治疗方法不同分为对照组（40例）、观察组（41例），对照组接受生物反馈治疗，观察组接受动态社交行为技巧练习联合生物反馈治疗。比较两组临床疗效、临床症状、社会功能、脑电波频率[β波、θ波、感觉运动节律（SMR）波]。结果 观察组总有效率90.24%较对照组的72.50%高（P＜0.05）；治疗后观察组对抗性行为、多动-冲动、注意力不集中评分均低于对照组（P＜0.05）；治疗后观察组家庭、学习与学校、生活技能、自我管理、社交活动及风险活动评分均低于对照组（P＜0.05）；治疗后观察组β波、SMR波均高于对照组，θ波低于对照组（P＜0.05）。结论 动态社交行为技巧练习联合生物反馈对学龄ADHD患儿临床疗效确切，可进一步改善患儿临床症状、社会功能。

Objective To explore the effect of dynamic social behavior skills training combined with biofeedback on clinical symptoms and social function in school-age children with attention deficit hyperactivity disorder (ADHD). Methods A total of 81 school-age children with ADHD admitted to our hospital from January 2021 to March 2024 were retrospectively selected as the research objects. According to different treatment methods, they were divided into control group (40 cases) and observation group (41 cases). The control group received biofeedback therapy, and the observation group received dynamic social behavior skills training combined with biofeedback therapy. The clinical efficacy, clinical symptoms, social function, brain wave frequency [β wave, θ wave, sensorimotor rhythm ( SMR ) wave] were compared between the two groups. Results The total effective rate of the observation group was 90.24% higher than that of the control group (72.50%) (P<0.05). After treatment, the scores of antagonistic behavior, hyperactivity-impulsion and inattention in the observation group were lower than those in the control group (P<0.05). After treatment, the scores of family, learning and school, life skills, self-management, social activities and risk activities in the observation group were lower than those in the control group (P<0.05). After treatment, the β wave and SMR wave in the observation group were higher than those in the control group, and the θ wave was lower than that in the control group (P<0.05). Conclusion Dynamic social behavior skill training combined with biofeedback has definite clinical efficacy in school-age children with ADHD, which can further improve their clinical symptoms and social functioning.
