Objective To compare the effica cy of three N,N-diethyl-m-toluamide (DEET) formulations against Schistosoma japonicum infection in mice. Methods Three 10% DEET formulations (DEET isopropanol solution,DEET cr eam and DEET vaseline ointment)were prepared and two experiments, no-dipping or dipping after applying DEET preparation ,were designed. In each experiment, mice were randomly divided into three experiment groups and three control groups . D ifferent DEET preparations were applied in the experiment groups and isopropanol solution, “yumeijing” cream , vaseline ointment were applied in the control g roups, respectively. At different time points after skin application (0.5, 1, 2 , 4 h and 8 h),the mice were infected with (50?5) Schistosoma j apon icum cercariae on the abdominal skin in no dipping experiment. I n dipping experiment,after mice skin were applied and were dipped for 10,30 min, 1 ,2 h and 4 h, respectively, the mice were infected with (50?5) cercariae. Af ter 6-7 weeks ,all the mice were sacrificed and the worms were collected by hea rt perfusion and counted.Worm reduction rates were calculated and rank sum tests w ere carried out. Results In no-dipping experim ent,three DEET formulations provided 100.0% protection in mice at least for 1 h .A t 2 ,4 h and 8 h ,the worm reduction rates were 94.8%,89.9% and 13.3% for DE ET isopropanol solution, 100.0%,97.8% and 50.7% for DEET cream and 100.0%,9 9.0% and 9 8.0% for DEET vaseline oinment, respectively. In dipping experi-ment, given 50.0% wor m reduction rate as efficient in preventing penetration by the cercariae, the e ffective times were 10 min for DEET isopropanol solution,30 min for DEET cream a nd 2 h for DEET vaseline oinment,respectively. Conclusion Three DEET formulations are effectiv e in preventing Schistosoma japonicum infection in mice.DEET vaseline oinment can provide better protection than the other two D EET formulations.

Background Attention deficit hyperactivity disorder (ADHD) is one of the most commonly diagnosed psychiatric disorder in childhood.ADHD children with overlapping symptoms and signs of motor problems have more serious prognosis than that of children with ADHD only.However,the motor and sensory processing problems in children with ADHD have not been studied well.Few people adopt the technique of computerized dynamic posturography (CDP) in the study of ADHD,which is applied widely in clinical and laboratory research to objectively evaluate human's balance performance.This study aimed to assess the characteristics of postural control and sensory information processing of boys with two subtypes of ADHD by using CDP,so as to provide the proof for non-drug therapy of ADHD.Method From June 2003 to September 2004,a total of 73 boys (7-15 years of age) with ADHD and 73 normal developing boys matched by age and intelligence quotient from Peking University Institute of Mental Health were recruited in the study.The Sensory Organization Test was adopted to test the static balance performance under six sensory input conditions by SMART EquiTest 8.0 (NeuroCom) instrument.The sensory information from three sensory systems were available under condition 1,the visual inputs were removed or distorted under condition 2 or 3,the somatosensory inputs were in conflict with or without the visual inputs removed under condition 4 or 5,and both the visual and somatosensory inputs were in conflict under condition 6.The indexes of equilibrium score,somatosensory,vestibular,and visual ratios,and strategy scores were analyzed to indicate the subjects' postural control ability.Results ADHD boys had significantly lower composite equilibrium score (CES) than the normal group (P <0.05).Under condition 1 and conditions 3-6,the equilibrium scores (ES) of the ADHD group were significantly lower (all P <0.05) than those of the control.Significantly lower visual and vestibular ratios and strategy scores under conditions 4-6 were found in boys with ADHD compared with the control group (P <0.05).Boys of ADHD-predominantly inattentive (ADHD-I) type had a significantly lower CES and ES under conditions 4-6 than the controls (all P <0.05) while the ESs of ADHD-combined type (ADHD-C) boys under each condition were similar with that of boys with ADHD-I and no significant difference was found between boys with ADHD-C and the control group (all P >0.05).Compared with the control group,the ADHD-I boys showed significantly lower visual and vestibular ratios and strategy scores under conditions 4-6 whereas the ADHD-C boys showed a trend of lower visual ratio (all P <0.05).Conclusions ADHD boys had a poorer static postural control ability and impaired function of processing visual and vestibular information compared with the normal control.Boys with ADHD-I showed particularly severe defect of static postural control and vestibular function integrating conflict information than normal boys.These deficits may be an important contributor to the clinical presentation of ADHD children and their cognitive deficits.Assessment and training of postural control function would be suggested during the diagnosis and treatment of ADHD children.

Objective:
To investigate the relationship between fine motor skills and executive function in school aged boys with attention deficit hyperactivity disorder (ADHD) aged 6-10 years, so as to provide a reference for promoting executive function.
Methods:
From November 2022 to May 2021,65 boys with ADHD were recruited from a tertiary hospital in Beijing and a public elementary school in Beijing, and 65 boys with typical development according to age and sex were recruited as controls. Children s fine motor skills were assessed using the movement assessment battery for children, second version (MABC-2), and children s inhibitory control, working memory, and cognitive flexibility were assessed using the Stroop color word test (SCWT), Rey osterrich complex figure test (ROCFT) and trail making test (TMT), respectively. Independent samples t-tests were used to analyze the differences between the two groups, and Pearson correlation analysis and stratified regression analysis were used to explore the relationship between fine motor skills and executive functioning in boys with ADHD.
Results:
In the fine motor skills test, boys with ADHD scored significantly lower (8.68±3.62) than control boys (11.22±2.27)( t =4.80, P <0.05); in the executive function test, the results of SCWT, ROCFT, and TMT tests were significantly worse in boys with ADHD than in normal boys ( t =-4.53-4.42, P < 0.05). Correlation analysis showed that the fine motor skill scores of boys with ADHD were negatively correlated with the number of word sense errors ( r =-0.35) and color errors ( r =-0.42), and positively correlated with memory scores for delayed structure ( r =0.30) and detail ( r =0.25), which were negatively correlated with TMT-A ( r =-0.34),TMT-B reaction time ( r =-0.26), number of errors ( r =-0.43) ( P <0.05). Stratified regression analysis showed that fine motor skill scores of boys with ADHD were predictive of test results for inhibitory control, working memory and cognitive flexibility, with explanatory rates of 15%, 7%, and 19%, respectively.
Conclusion
Fine motor skills in boys with ADHD are correlated with executive functions, and fine motor skills could predict inhibitory control, working memory and cognitive flexibility to some extent. The development of fine motor skills in boy with ADHD could promote their executive functions.

Chinese Journal of School Health 2019;40(8):1194-1199
Objective:
The cross-sectional study examined associations between gross motor competence and physical fitness in 3-5 years old children.
Methods:
A convenient sampling method was used to select 201 children aged 3-5 years, to assess gross motor competence, each child accomplished the Test of Gross Motor Development-3(TGMD-3). The level of physical fitness was measured by National Physical Fitness Test, comprising eight different tasks including height, weight, flexibility(sit-and-reach test), balance (walking on a balance beam), explosive force(Standing long jump), strength(Tennis ball throwing), agility(10-shuttle-run test), strength and coordination(Continuous foot jump).
Results:
With the increase of age, the scores of locomotor skills,object control skills, gross motor competence, height, weight, walking on a balance beam, continuous foot jump, tennis ball throwing and standing long jump were better(P<0.01). Significant differences were not found in the gross motor competence, locomotor skills, 10-shuttle-run test, continuous foot jump, standing long jump and walking on a balance beam(P>0.05). In the object control skills and tennis ball throwing, the boys showed a greater performance(P<0.01). In the sit-and-reach test, girls showed a greater performance(P<0.01). The results revealed a significant relationship between gross motor competence and the following items: 10-shuttle-run test, continuous foot jump, standing long jump, walking on a balance beam, tennis ball throwing(P<0.05). There were no associations among gross motor competence, BMI(r=0.02), sit-and-reach test(r=0.07). There were no associations between gross motor competence and physical fitness in 3-5 years old(r=-0.13-0.21), except for 5 years old children’s object control skills and continuous foot jump(r=0.42). Sex, age, height , BMI (R2=0.05,F=2.62, P>0.05) as well as gross motor competence(△R2=0.04, F=2.00, P>0.05) did not predict physical fitness.
Conclusion
The results indicated a relationship between motor competence and physical fitness in 3-5 years old. In order to increase the level of physical fitness, the educators should pay attention to the development of children’s gross motor.

Objective:To explore the effect of acute exercise on the executive function in patients with atten-tion deficit hyperactivity disorder(ADHD),and to provide a theoretical basis for the exercise intervention of ADHD.Methods:Experimental studies on the effect of acute exercise on executive function in patients with ADHD published up to 21 April 2023 were searched from PubMed,Web of Science,Cochrane Library,Embase,CNKI,Wanfang,and other data platforms.Results:A total of 15 studies were included,and 515 patients with ADHD were included.The results of meta-analysis showed that a single exercise could improve inhibitory control(SMD=0.36,95%CI=0.17-0.55,P<0.05)and cognitive flexibility(SMD=0.40,95%CI=0.10-0.69,P<0.05)in pa-tients with ADHD.The results of subgroup analysis showed that in terms of the age of the participants,a single ex-ercise could only improve inhibitory control and cognitive flexibility in children and adolescents with ADHD(SMD=0.36,0.43,Ps<0.05),but not in adult patients with ADHD(SMD=0.34,0.14,Ps>0.05).In terms of exer-cise regimen,only a single exercise with moderate and high intensity,≤ 20 minutes,and open motor skills could simultaneously improve inhibitory control(SMD=0.47,0.51,0.47,Ps<0.05)and cognitive flexibility(SMD=0.86,0.65,0.86,Ps<0.05)in patients with ADHD.Conclusion:Acute exercise could improve inhibitory control and cognitive flexibility in children and adolescents with ADHD,but has no significant effect on working memory and executive function in adult patients.
9.Tracking observation of fine motor development in children aged 6-8 with attention deficit hyperactivity disorder
Chinese Journal of School Health 2024;45(6):831-834
Objective:
To examine the developmental trajectory of fine motor ability in schoolage children with attention deficit hyperactivity disorder (ADHD) for two years, so as to provide scientific evidence to promote motor development in ADHD children.
Methods:
From April to June 2019, 31 children aged 6-8 years old were selected from a public elementary school. They were diagnosed with ADHD by two psychiatric professionals according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Additionally, 31 typical developmental children, matched for age, sex and IQ with the ADHD group, were recruited as the control group. Fine motor ability was assessed with tasks of hand manual dexterity in Movement Assessment Battery for Children-2 (MACB-2), and a followup assessment was conducted from April to June 2021. The development changes of fine motor ability between two groups of children were compared by using t test and repeated measures analysis of variance.
Results:
Between baseline and followup periods after two years, the total score of hand fine motor in the ADHD group did not show significant improvement (7.4±3.0, 8.0±3.4; t=-1.05, P>0.05), while there was a small effect size improvement in typically developing control group (9.5±2.1, 10.5±2.4; t=-2.12, effect size=0.38, P<0.05). Followup after two years, coin/peg throwing scores with dominant hand improved between ADHD group and control group (7.0±3.3, 9.5±3.2; 8.4±2.8, 11.6±1.6) (t=-3.74, -6.33, P<0.01; effect size=0.67, 1.14), with a smaller improvement in the ADHD group. The score for threading beads/threads decreased in between ADHD group and control group (7.9±2.4, 5.8±3.1; 9.2±1.1, 8.2±1.9) (t=3.89, 2.78, P<0.01; effect size=0.70, 0.50), with a greater decrease in the ADHD group.
Conclusions
The development speed of fine motor ability in children with ADHD aged 6-8 is slow and continues to lag behind normal developmental children. Fine motor development in children with ADHD should be closely monitored, and targeted interventions should be implemented when necessary.
