目的 探讨亲子合作式音乐疗法对孤独症谱系障碍（autism spectrum disorder,ASD）儿童的核心症状及其母亲的影响。 方法 前瞻性采用随机数字表法将112例ASD儿童及其母亲分为音乐疗法组和应用行为分析法（applied behavior analysis,ABA）组,每组各56例。ABA组采用ABA进行干预,音乐疗法组在ABA组基础上采用亲子合作式音乐疗法。2组干预时长均为8周。采用儿童孤独症评估量表（Childhood Autism Rating Scale,CARS）、儿童孤独症家长评定量表（Autism Behavior Checklist,ABC）、亲职压力简表（Parenting Stress Index-Short Form,PSI-SF）、家庭关怀度指数量表（Family APGAR Index,APGAR）和Herth希望量表（Herth Hope Index,HHI）,评估干预前和干预后ASD儿童的核心症状及其母亲的亲职压力、家庭关怀度和希望水平。 结果 共100对母子参与了全程研究（每组各50对）。干预后音乐疗法组ASD儿童ABC量表总分、感觉维度、社交维度、躯体运动维度得分,以及CARS量表总分低于ABA组（P<0.05）。干预后音乐疗法组母亲的PSI-SF总分、亲子互动失调维度得分,HHI量表总分和各维度得分,以及APGAR量表总分、合作度和亲密度得分均高于ABA组（P<0.05）。 结论 在ABA的基础上,加用亲子合作式音乐疗法可改善ASD儿童的核心症状,减轻母亲的亲职压力,提升其家庭关怀度指数和希望水平。 引用格式：中国当代儿科杂志,2022,24（5）：472-481     

Efficacy of plasma exchange in children with severe hemophagocytic syndrome: a prospective randomized controlled trial北大核心CSCD

目的 探讨血浆置换在辅助救治儿童重症噬血细胞综合征（hemophagocytic syndrome,HPS）中的疗效和应用价值。 方法 采用前瞻性随机对照研究方法,选取2018年10月至2020年10月在湖南省儿童医院儿童重症监护室（pediatric intensive care unit,PICU）接受救治的重症HPS患儿40例为研究对象,将患儿随机分为置换组和常规组（n=20）,常规组患儿进行病因和对症常规支持治疗,置换组在常规治疗的基础上加以血浆置换辅助治疗。对两组患儿的基本情况、治疗前后的临床症状体征、主要实验室检查指标、疗效和预后情况进行比较分析。 结果 两组患儿治疗前在性别、年龄、入院前病程、病因构成、小儿危重病例评分、器官或系统功能累及情况等指标上比较差异均无统计学意义（P>0.05）,在实验室指标的比较上差异亦均无统计学意义（P>0.05）。两组患儿治疗7 d后,临床症状体征均有所缓解和改善。治疗后置换组C反应蛋白、降钙素原、血清铁蛋白、丙氨酸氨基转移酶、总胆红素水平均低于常规组（P<0.05）。置换组的PICU住院时间较常规组明显缩短,总有效率较常规组明显提高（P<0.05）,但两组总的住院时间和3个月病死率比较差异无统计学意义（P>0.05）。 结论 血浆置换在辅助治疗儿童重症HPS上的疗效优于常规治疗,能改善患儿的临床症状体征和部分实验室指标,缩短PICU住院时间,可能成为治疗儿童重症HPS的一项有效辅助治疗方法。     

Clinical assessment of moderate-dose glucocorticoid in the treatment of recurrence of primary nephrotic syndrome in children: a prospective randomized controlled trial北大核心CSCD

Objective To study the clinical effect and adverse drug reactions of different doses of glucocorticoid (GC) in the treatment of children with recurrence of steroid-sensitive nephrotic syndrome (SSNS). Methods A total of 67 children who were hospitalized and diagnosed with SSNS recurrence in the Department of Nephrology, Children's Hospital, Capital Institute of Pediatrics, from November 2017 to December 2019 were enrolled. They were randomly divided into a moderate-dose GC group (32 children) and a full-dose GC group (35 children). The two groups were compared in terms of urinary protein clearance, recurrence rate within 6 months, and incidence rate of GC-associated adverse reactions. Results There was no significant difference in the urinary protein clearance rate between the moderate-dose GC and full-dose GC groups (91% vs 94%, P>0.05). There was also no significant difference in the recurrence rate within 6 months between the two groups (41% vs 36%, P>0.05). At 6 months of follow-up, compared with the full-dose GC group, the moderate-dose GC group had a significantly lower cumulative dose of prednisone [(87± 18) mg/kg vs (98±16) mg/kg, P=0.039 and a significantly lower proportion of children with an abnormal increase in body weight (6% vs 33%, P=0.045). The logistic regression analysis showed that prednisone dose ≥10 mg/alternate day at enrollment was a risk factor for recurrence within 6 months in children with SSNS (P=0.018). Conclusions For children with SSNS recurrence, moderate-dose GC has similar effects to full-dose GC in the remission induction rate and the recurrence rate within 6 months, with a lower cumulative dose and fewer GC-associated adverse reactions within 6 months than full-dose GC. © 2022 Central South University.

目的建立支气管哮喘(哮喘)患儿肺功能长期变化的发展轨迹, 确定哮喘患儿出现长期肺功能损伤的危险因素。方法采用回顾性队列研究, 纳入2019年1月至12月在首都儿科研究所附属儿童医院定期随诊, 并完成肺功能检测的14岁以上哮喘患儿, 收集其肺功能资料及临床信息。采用潜变量增长模型(LCGM)拟合哮喘患儿肺功能发展轨迹, 建立不同的轨迹组, 组间比较采用t检验、方差分析或χ2检验, 确定肺功能长期变化危险因素采用多分类Logistic回归分析。结果共纳入哮喘患儿173例, 年龄6~17岁, 获得肺功能测定1 160例次。拟合4条1秒率(FEV1/FVC)潜分类轨迹:持续高水平组、高于平均水平组、低于平均水平组、持续低水平组, 其病例数分别为27例(15.6%)、66例(38.1%)、66例(38.1%)、14例(8.1%)。不同轨迹组患儿的FEV1/FVC在每一年龄组间的差异均有统计学意义(均P<0.05)。持续高水平组各年龄段的FEV1/FVC均在90%以上, 其余各轨迹组FEV1/FVC随年龄变化整体呈下降趋势, 低于平均水平组的FEV1/FVC在青春期后下降至80%以下;持续低水平组的FEV1/FVC均值在学龄期后即下降至80%以下, 至青春期接近70%。最大用力呼气中段流量(MMEF)的轨迹和波动情况与FEV1/FVC相似。危险因素分析显示, 与持续高水平组相比, 典型哮喘患儿肺功能轨迹处于低于平均水平组的风险是咳嗽变异性哮喘患儿的11.940倍(P=0.008);多重致敏患儿的肺功能轨迹处于低于平均水平组的风险是单一致敏的7.462倍(P=0.015);未规律用药患儿肺功能处于持续低水平组的风险是规律用药者的6.337倍(P=0.035);男童肺功能轨迹处于低于平均水平组的风险是女童的6.186倍(P=0.002)。结论 6~17岁哮喘患儿的长期肺功能变化可确定4条不同轨迹:持续高水平、高于平均水平、低于平均水平、持续低水平;近半数患儿的长期肺功能轨迹处于低水平, 较多患儿在青春期, 少数患儿在学龄期出现持续性气流受限;典型哮喘、多重致敏、未规律用药、男性是哮喘患儿长期肺功能降低的危险因素。     

Serum free fatty acid level in children with primary hypertension北大核心CSCD

目的研究儿童原发性高血压血清游离脂肪酸(free fatty acid,FFA)的水平,探讨其在儿童原发性高血压发病和防治中的临床意义。方法回顾性选取2021年1—6月首都儿科研究所附属儿童医院初治的34例原发性高血压儿童为高血压组,以同期体检的血压正常儿童32例为对照组。比较2组的空腹血清FFA、空腹血清三酰甘油(triglyceride,TG)、总胆固醇(total cholesterol,TC)、低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)、高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)和非高密度脂蛋白胆固醇(non-high-density lipoprotein cholesterol,non-HDL-C)水平。采用多因素logistic回归分析探讨血清FFA对原发性高血压发病的影响。结果高血压组体重指数(body mass index,BMI)、收缩压(systolic blood pressure,SBP)、舒张压(diastolic blood pressure,DBP)高于对照组,差异有统计学意义(P<0.05)。高血压组血清FFA、TG、LDL-C、non-HDL-C高于对照组,而血清HDL-C低于对照组,差异均有统计学意义(P<0.05)。高血压组血清FFA升高(女性>0.45 mmol/L,男性>0.60 mmol/L)率和传统血脂异常(血清TG、TC、LDL-C、HDL-C、non-HDL-C中至少一项异常)率均高于对照组,差异有统计学意义(P<0.05)。纳入年龄、性别、BMI、血清FFA升高、传统血脂异常等指标构建多因素logistic回归方程,结果显示血清FFA升高是儿童原发性高血压的独立危险因素(OR=17.560,95%CI:1.964~157.003,P<0.05)。结论原发性高血压儿童血清FFA明显升高;血清FFA升高可增加儿童原发性高血压的发病风险。     

Detection of RAS gene mutation and its clinical significance in children with acute lymphoblastic leukemia北大核心CSCD

Objective To investigate the mutation rate of the RAS gene and its clinical significance in children with acute lymphoblastic leukemia. Methods A retrospective analysis was performed on the medical data of 120 children with newly diagnosed acute lymphoblastic leukemia, who were admitted to the Third Affiliated Hospital of Zhengzhou University from January 2015 to January 2020 and underwent next-generation sequencing. The clinical and molecular features were analyzed. The impact of RAS gene mutation on the overall survival rate was evaluated in these children. Results Among the 120 children, 35 (29.2%) had RAS gene mutation, 30 (25.0%) had KRAS gene mutation, and 5 (4.2%) had both NRAS and KRAS gene mutations. All NRAS mutations and 71% (25/35) of KRAS mutations were located at the 12th and 13th codons. RAS gene mutation was detected in 35 (33.3%) out of 105 children with B-lineage acute lymphoblastic leukemia, but it was not detected in those with acute T lymphocyte leukemia. Of all the children, 11 (9.2%) were lost to follow-up, and among the 109 children followed up, 16 (14.7%) died. The children with RAS gene mutation had a significantly lower 2-year overall survival rate than those without RAS gene mutation (P<0.05). The prognosis of children with RAS gene mutation combined with WT1 overexpression and WBC>50×109/L at diagnosis was worse (P<0.05). Conclusions RAS gene mutation is commonly observed in children with B-lineage acute lymphoblastic leukemia and may have an adverse effect on prognosis. © 2022 Xiangya Hospital of CSU.

Methods Clinical features and laboratory results of 270 cases with IM admitted to the Department of Pediatrics in Strategic Support Force Medical Center of People's Liberation Army from January 2012 to December 2020 were retrospectively analyzed. χ2 test was used for comparison between groups. Results IM mainly occurred in children aged 5 months to 18 years old in autumn and spring. The highest incidence rate (105 cases, 38.9 %) was 3 - <6 years old (preschoolers). There were 253 cases (93.7%) with fever, 266 cases (98.5 %) with adenopharyngitis, 196 cases (72.6%) with tonsil pseudomembrane or exudation, 248 cases (91.9%) with cervical lymphadenopathy, 92 cases (34.1%) with eyelid edema, 202 cases (74.8%) with nasal obstruction, 124 cases (45.9%) with nasal obstruction and snoring, 24 cases (8. 9 %) with rash, and 112 cases (41.5%) with splenomegaly. A total of 225 cases (83.3%) presented with typical triplets of IM (fever, adenopharyngitis and cervical lymphadenopathy). Sixty - two IM patients were complicated with pulmonary infections and 3 cases with diarrhea. The main co - infection pathogens in children with IM were Mycoplasma pneumonia (M P) (79 cases, 29.3%), influenza A or B virus (34 cases, 12.6%), Streptococcus pneumonia (S P) (18 cases, 6.7%), adenovirus (22 cases, 8.1%) and cytomegalovirus (3 cases, 1.11%). A total of 46 cases (17.0%) had multiple infections. Laboratory test results suggested that absolute lymphocyte count 5. 0 x 109/L was found in 199 cases (73.7%), and abnormal lymphocyte ratio > 0.10 was found in 225 cases (83.3%). Some children had elevated transaminase levels. Epstein - Barr virus capsid antigen - immunoglobulin M (EBV - VCA - IgM) was positive in 249 cases (92.2%), Epstein - Barr virus capsid antigen - immunoglobulin G (EBV - VCA - IgG) was positive in 238 cases (88.1%), and Epstein - Barr virus nuclear antigen - immunoglobulin G (EBV - NA - IgG) was negative in all cases. EBV - VCA - IgG showed low affinity in all cases (< 40%). EBV DNA tests of peripheral blood plasma were carried in 153 cases, of which 118 cases (77.1%) were positive. Conclusions EBV related IM mainly attacks preschoolers. Most patients are presented with typical triplets of IM. Eyelid edema, nasal obstruction, snoring, splenomegaly and elevated transaminase levels are prevalent in IM children. Most cases have a favorable prognosis. © 2022 ＣｈｉｎＪＡｐｐｌＣｌｉｎＰｅｄｉａｔ.
