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．

Objective To explore the therapeutic efficacy of Qingke Pingchuan granules combined with acetylcysteine on children with lobar pneumonia (LP) of phlegm-heat obstructing lung type. Methods A total of 118 children with LP of phlegm-heat obstructing lung type admitted to our hospital from January 2023 to November 2025 were retrospectively selected as the research subjects. According to different treatment regimens, they were divided into the control group (59 cases, treated with acetylcysteine) and the combined group (59 cases, treated with Qingke Pingchuan granules combined with acetylcysteine). The clinical efficacy, adverse reactions, as well as the levels of pulmonary function indicators [tidal volume (VT), time to peak tidal expiratory flow ratio (TPTEF/TE), inspiration-expiration ratio (Ti/Te), volume to peak tidal expiratory flow ratio (VPEF/VE)], traditional Chinese medicine (TCM) syndrome scores, immune function and inflammatory factors [interleukin-8 (IL-8), C-C motif chemokine ligand 3 (CCL3), tumor necrosis factor-α (TNF-α), high mobility group box 1 protein (HMGB1)] before and after treatment were compared between the two groups. Results The total effective rate of the combined group was 96.61%, which was higher than 83.05% of the control group (P<0.05). After treatment, the TCM syndrome scores of the combined group were lower than those of the control group (P<0.05). The levels of VT, TPTEF/TE, Ti/Te and VPEF/VE in the combined group were higher than those in the control group after treatment (P<0.05). After treatment, the level of CD8? in the combined group was lower, while the levels of CD3?, CD4? and CD4?/CD8? were higher than those in the control group (P<0.05). The serum levels of IL-8, CCL3, TNF-α and HMGB1 in the combined group were significantly lower than those in the control group after treatment (P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion The combination of Qingke Pingchuan granules and acetylcysteine can enhance the therapeutic efficacy on children with LP of phlegm-heat obstructing lung type, relieve clinical symptoms, improve pulmonary function and immune function, and reduce systemic inflammatory response.

Objective To analyze the distribution of pathogens and the epidemiological characteristics of children with acute lower respiratory tract infections (ALRTI) admitted to Zhengzhou People’s Hospital from February 2024 to February 2026. Methods: A total of 193 pediatric patients with ALRTI who visited Zhengzhou People’s Hospital between February 2024 and February 2026 were selected as study subjects. Throat swab samples were collected from the patients, and pathogen testing results were compiled to compare the distribution of pathogens across different genders, age groups, and seasons of onset. Results: Among the 193 children, 165 tested positive for pathogens, resulting in an overall positive detection rate of 85.49%. The top three most frequently detected pathogens were RSV (20.73%), MP (19.69%), and HRV (15.54%); RSV infection had the highest prevalence (44.83%) among infants, followed by HRV infection (20.69%). Among preschoolers, the prevalence of RSV, HRV, and MP infections (17.31%, 17.31%, and 19.23%, respectively) was relatively high. MP infections were most common among preschool and school-age children (33.33% and 26.32%, respectively); the proportion of mixed infections was lower among infants (6.90%) but higher among preschoolers (20.00%); In spring, the distribution of pathogens was relatively balanced, with high proportions of HRV, MP, and SP infections (14.58%, 12.50%, and 14.58%, respectively). In summer and fall, the MP infection rate was high (31.82% and 28.85%, respectively). In winter, the RSV infection rate (55.10%) was high. The proportion of children with mixed infections was relatively similar across the four seasons, with a relatively higher infection rate (17.31%) in autumn. Conclusion: Among the pathogens identified in children with acute lower respiratory tract infections admitted to Zhengzhou People’s Hospital from 2024 to 2026, RSV and MP were the primary pathogens. The incidence peaks of various respiratory pathogens varied according to the children’s age groups and seasons. Clinicians should conduct early pathogen identification based on actual conditions to guide the development of targeted treatment plans and improve patient outcomes.

目的 调查儿童川崎病（KD）冠状动脉损伤发生情况,并进行危险因素分析。方法 选择2018年1月—2022年12月在泉州市妇幼保健院儿童医院诊治的KD儿童782例为研究对象,所有患儿在入院时均给予超声检查,判定冠状动脉损伤情况,调查所有患儿的一般资料,进行危险因素分析。结果 782例患儿中,超声判断为冠状动脉损伤171例,占比21.9%（冠脉损伤组）,无冠状动脉损伤611例（无冠脉损伤组）。冠脉损伤组的皮疹、肢端硬性红肿、球结膜充血、杨梅舌等临床表现占比分别为83.6%、67.8%、86.0%、81.9%,高于无冠脉损伤组的63.5%、49.7%、62.5%、65.3%（P<0.05）。冠脉损伤组与无冠脉损伤组的性别、年龄、血红蛋白、血红细胞沉降率（ESR）等比较差异无统计学意义（P>0.05）,冠脉损伤组的丙氨酸氨基转移酶、白细胞计数（WBC）、D-二聚体（D-D）、C-反应蛋白（CRP）、降钙素原（PCT）、血小板计数（PLT）、发热时间与无冠脉损伤组比较差异有统计学意义（P<0.05）。多因素Logistic逐步回归分析显示,WBC、D-D、CRP、PCT、PLT、发热时间均为川崎病患儿发生冠状动脉损伤的影响因素（P<0.05）。结论 KD儿童中,冠状动脉损伤发生率较高,可导致患儿临床特征多样化,加重患儿的病情,WBC、D-D、CRP、PCT、PLT、发热时间为导致冠状动脉损伤发生的影响因素。

Objective To investigate the incidence of coronary artery injury in children with Kawasaki disease（KD）and analyze the risk factors．Methods From January 2018 to December 2022,782 children with KD diagnosed and treated in Quanzhou Women’s and Children’s Hospital were selected as the study subjects．All the children were given ultrasound examination on admission to determine the coronary artery injury level．The general information of all the children was investigated and the risk factors were analyzed．Results Among the 782 children,171 cases（21.9%）were diagnosed as the“coronary artery injury group”．The remaining 611 patients did not exhibit any coronary artery injury and were thus categorized as the“no coronary artery injury group”．The clinical manifestations incidences of rashes,hard red swelling of extremity,bulbar conjunctival congestion and bayberry tongue in the coronary injury group were 83.6%,67.8%,86.0% and 81.9%,respectively,which were significantly higher than those in the non-coronary injury group（63.5%,49.7%,62.5% and 65.3%,P<0.05）．There were no significant differences in gender,age,hemoglobin and erythrocyte sedimentation rate between the coronary injury group and the no coronary injury group（P>0.05）．There were significant differences in alanine aminotransferase,white blood cell count（WBC）,D-dimer（D-D）,C-reactive protein（CRP）,procalcitonin（PCT）,platelet count（PLT）and fever duration between the two groups（P<0.05）．Multivariate Logistic stepwise regression analysis showed that WBC,D-D,CRP,PCT and PLT were all important factors leading to coronary artery injury（P<0.05）．Conclusions The incidence of coronary artery injury in children with KD is relatively high,which can lead to the diversification of clinical features and disease aggravation of children．WBC,D-D,CRP,PCT,PLT and fever duration are important risk factors for the occurrence of coronary artery injury．
