AIM: To evaluate the influences of triptolide on serum cytokines, symptoms and pulmonary function in patients with steroid - resistant asthma, so as to investigate if there is therapeutic effect of triptolide on these patients. METHODS: Sixteen patients with steroid - resistant asthma were randomly divided into two groups (A and B, n =8 for each group). All of the patients took procaterol (50 - 100 μg/d) and theophylline (400 mg/d) orally as baseline treatment. Additionally, triptolide was prescribed for group A (33 μg, orally, three times per day for 4 weeks). Asthmatic symptom score calculation, serum cytokines ( interferon - γ, IFN - γ; interleukin - 4, IL - 4; and interleukin - 5, IL - 5)determination and pulmonary function test (FVC%, FEV1%, PEF%, V50% and V25% ) were undertaken before and at the end of the study. RESULTS: At baseline, no significant difference was found between group A and group B with respect to the above mentioned indices. Following the administration of triptolide, group A had significantly increased serum IFN -γlevel, FVC%, FEV1%, PEF%, V50% and V25%, and significantly decreased asthmatic symptom score and serum IL-4, IL-5 levels (P<0.01 compared with baseline in the same group, and P<0.05 compared with group B at the end of the study). Compared with baseline, no significant change was observed for group B regarding all the indices at the end of the study. CONCLUSION: Triptolide in combination with procaterol and theophylline may be a novel and effective strategy for the treatment of steroid - resistant asthma.

Autism spectrum disorders(ASD)is an important disease in children′s neuropsychic development disorder.The incidence rate is increasing now, which brings heavy burden to family and society.Functional studies of ASD related different single gene mutation models have showed that these overlapping phenotypes shared the common mechanism of the homeostatic synaptic plasticity impairment.Retinoic acid receptor α(RARα)regulate synaptic plasticity of the nervous system in both directions, through glutamate receptor subunit 1(GluR1)translation and RARα/mTOR signaling pathway, and affect the integration of sensory information and situational adaptive learning, and then affect the learning and memory function and neural synaptic signal network through the growth of dendritic spines.These researches suggest that RARα may work as a potential drug target for ASD, playing an important role in stable regulation of homeostatic synaptic plasticity, which is helpful for molecular typing accurate diagnosis and treatment of ASD.

Objective:To investigate the correlation between social and linguistic parenting behaviors and developing capability of children with autism.Methods:From August 2020 to December 2020, the social and linguistic parenting behaviors of 302 parents of children diagnosed with autism were investigated in the outpatient department of the hospital.Meanwhile, the data of Gesell scale for children, the social life competence scale for infant and junior middle school students, the autism behavior checklist and the Cancy autism behavior scale were collected.SPSS 20.0 software was used for statistical analysis.Independent sample t test and analysis of variance were used to compare the social and linguistic parenting behaviors of different parents.Pearson correlation analysis was used to analyze the correlation between the social and linguistic parenting behaviors of parents and children's developmental ability and symptom severity. Results:There were no statistically significant differences in children's social and language development parenting behavior between father and mother ( t=1.033, P=0.303; t=-0.312, P=0.756). There were no statistically significant differences in children's social and linguistic parenting behaviors between fathers of different age groups ( F=1.425, P=0.244; F=1.127, P=0.345). Among mothers of different age groups, the social parenting behaviors of <30 years old and 30-34 years old groups were significantly better than those of 35-39 years old group ( F=3.374, P=0.019; LSD: P=0.010, P=0.006). Among fathers, the social parenting behavior( F=4.346, P=0.008; LSD: P=0.020, P=0.001) and social + linguistic parenting behavior in the graduate group and college group were significantly better than those in the high school/vocational group( F=3.965, P=0.012; LSD: P=0.020, P=0.002). Among mothers, the social parenting behavior ( F=2.812, P=0.040; LSD: P=0.008, P=0.023, P=0.009), linguistic parenting behavior ( F=3.769, P=0.011; LSD: P=0.010, P=0.025, P=0.001), social + linguistic parenting behavior ( F=3.654, P=0.013; LSD: P=0.005, P=0.015, P=0.002) in graduate and above groups were significantly better than those in college group, high school/vocational group, junior high school and below groups.The scores of social parenting behavior(40.72±6.80), linguistic parenting behavior(27.20±5.22), and social + linguistic parenting behavior(67.92±11.10) were significantly correlated with children’s fine motor(61.75±16.41)( r=0.193, P=0.001; r=0.153, P=0.009; r=0.190, P=0.001), cognition(68.28±16.83)( r=0.231, P=0.000; r=0.186, P=0.001; r=0.229, P=0.000), language(53.01±18.55) ( r=0.262, P=0.000; r=0.305, P=0.000; r=0.304, P=0.000) and social self-care(61.44±17.85) ( r=0.264, P=0.000; r=0.238, P=0.000; r=0.274, P=0.000). The scores of linguistic parenting behavior and social + linguistic parenting behavior were correlated with children's social life ability (8.65±0.89) ( r=0.142, P=0.046; r=0.140, P=0.049). There was no significant correlation between social parenting behavior, linguistic parenting behavior, social + linguistic parenting behavior and the scores of ABC scale (50.53±21.39) ( r=-0.089, P=0.336; r=-0.115, P=0.215; r=-0.107, P=0.250) and CABS scale (13.96±4.54) ( r=-0.050, P=0.490; r=-0.059, P=0.411; r=-0.058, P=0.421). Conclusions:The social and linguistic parenting behaviors are related to their age and educational level, and are significantly correlated to developing capability of children with autism, but have nothing to do with the severity of children's symptoms.

Objective:To understand the health status of children in an organization in the urban area of Beijing.Methods:From October to November 2019, 558 children aged from 0 to 13 of employees in an organization in Beijing received physical examination, including height, weight, ophthalmology and otorhinolaryngology, heart and lung examination, etc.Statistical analysis was conducted on the items related to physical status and with higher detection rate. Body mass index (BMI)≥P 85(P is the percentile compared to the standardized growth curve) was defined as overweight and BMI≥P 95 as obese. The rate and composition ratio were used to describe the relevant data of each item in children′s physical examination. The differences between different age groups and gender groups were compared with the chi-square test. Results:The items with high detection rate were overweight, obesity, rhinitis, caries, phimosis, etc. The ratio of children′s weight and height ≤P 10 were 3.4% and 2.7%, ≥P 97 were 12.0% and 7.0%respectively; the rates of overweight (BMI≥P 85) and obesity (BMI≥P 95) in children were 13.8% and 13.3% respectively, the ratio of weight ≥P 97, height ≥P 97 and BMI≥P 95all increased with age in all children and in boys (all P<0.05), the ratio of BMI≤P 5 increased with age ( P<0.05), and the ratio of body weight ≥P 75 decreased with age in boys ( P<0.05); the ratio of weight ≥P 75 in boys was significantly higher than that in girls ( P<0.05). The prevalence of rhinitis in children was 39.8%, among which the prevalence of allergic rhinitis was 14.9%.The prevalence of allergic rhinitis in the 3.0-5.9 age group of all children was significantly higher than that in 0.0-0.9 age group and 6.0-9.9 age group (both P<0.05), the prevalence of total rhinitis in the 3.0-5.9 age group of girls was significantly higher than that in 0.0-0.9 age group, 1.0-2.9 age group and 10.0-13.9 age group (all P<0.05). The prevalence of dental caries in children (excluding the group of 0.0-0.9 years old) was 26.0%, the prevalence of dental caries in the 3.0-5.9 age group of all children was significantly higher than that in 1.0-2.9 age group and 10.0-13.9 age group (both P<0.05), the prevalence of dental caries in 3.0-5.9 age group and 6.0-9.9 age group of boys and girls were both significantly higher than that in 1.0-2.9 age group (all P<0.05). The prevalence of phimosis in boyswas 31.5%, the phimosis rates were significantly higher in the 1.0-2.9 age group and 3.0-5.9 age group than that in 6.0-9.9 age group and 10.0-13.9 age group (all P<0.05). No statistical differences were found in the prevalence of allergic rhinitis and dental caries between obese and non-obese children ( P>0.05). Conclusion:The severity of overweight and obesity in children is beyond our expectation, the allergenicity problem is becoming more and more prominent, the prevention and treatment of dental caries needs to be improved urgently, and the phimosis problem in boys needs to be paid attention to.

Objective:To understand the identification value of pointing gestures in children with autism spectrum disorder(ASD) and its relationship with functional development.Methods:From December 2020 to November 2021, 1 099 children from Children’s Health Care Center of Beijing Children’s Hospital were tested by pointing gestures test, including 942 ASD children and 157 typical developed children.And the data of children's neuropsychological development scale from 800 children aged 1.0-5.9 were collected.SPSS 20.0 was used for statistical analysis. Trend test was used to analyze the distribution of pointing gestures test sensitivity in autistic children, and ANOVA was used to analyze the relationship between pointing gestures test scores and functional development fields.Results:The sensitivity of pointing gestures was 83.5% in children aged 1.0-10.0 years, 76.3%-93.1% in children aged 1.0-4.9 years, and 93.1%-95.1% in children aged 1.0-2.9.With the increase of age, the sensitivity of pointing gestures in autistic children (linear-by-linear association =164.889, P<0.001) and the Yoden index had a decreasing trend. The positive predictive value (91.53%-100.00%) and negative predictive value (75.36%-91.84%) were found in the children aged 1.0-10.0 years.The sensitivity of pointing gestures test was 44.9% in children with mild autism aged 1.0-10.0 years and 46.5%-65.9% in children with mild autism aged from 1.0-3.9 years. The sensitivity of pointing gestures test was 81.5% in children with moderate autism aged from 1.0-10.0 years and 87.3%-97.8% in children with moderate autism aged 1.0-3.9 years. The sensitivity of the pointing gestures test was 97.2% in children with severe autism aged 1.0-10.0 years, and 100.0% in children with severe autism aged 1.0-3.9 years. The sensitivity of the pointing gestures in mild, moderate and severe autism children decreased with age (linear-by-linear association values were 16.725, 64.232, 66.732 respectively, all P<0.001). The children with severe autism mainly scored 2 points (80.3%, 419/522) on the pointing gestures test , and children with moderate autism mainly scored 1 point(64.2%, 170/265) on the pointing gestures test. There were significant differences in functional development among different pointing gestures test groups.Functional development score in the autism children with 0 score of pointing gestures test was significantly higher than those with 1 score and 2 scores of pointing gestures test (all P<0.05). Conclusion:Pointing gestures has good sensitivity in children with autism (especially 1.0-4.9 years of age), and may serve as an objectively observable screening method. The better children with autism score on the pointing gestures, the better their functional development.
