Objective:To examine the association between parental characteristics and risk of autism spectrum disorder (ASD) in children.Methods:In this case-control study, the cases were defined as children who were diagnosed with ASD and were recruited from June 2018 to February 2019 in Shanghai Mental Center ( n=104). The controls were defined as children who did not have ASD and were recruited in the two community health centers in Jing-an District of Shanghai during the same period ( n=149). All children recruited in this study were 2-6 years old. A multivariate logistic regression model was used to examine the association between parental characteristics and the risk of ASD in offspring, and further to estimate the interaction coefficient. Results:According to multivariate regression analysis, the association between maternal age, previous pregnancy complication and the risk of ASD in children appeared to be not statistically significant. After adjusted, advanced paternal age (≥35 years old)( OR=3.65, 95% CI=1.19-11.15, P=0.023), parental disease before or during pregnancy ( OR=3.34, 95% CI=1.41-7.94, P=0.006) and gender of child (male) ( OR=5.84, 95% CI=2.98-11.44, P<0.001) were associated with increased risk of ASD. The results also showed that the boys whose father was 35 years old or more had a higher risk of ASD than the boys whose fahter was less 35 years old and the girls whose father was 35 years old or more ( P=0.005, P=0.006). Conclusion:Advanced paternal age was associated with increased risk of ASD in offspring and this effect may be more pronounced in boys.

Influenza virus has a continuous and extensive impact on human health around the world. Its extensive animal host characteristics and highly variable characteristics lead to continuous antigen drift and change of susceptible populations, causing repeated global influenza epidemics, and also affecting the protective effect of seasonal influenza vaccine. This research in a number of subtypes of influenza a virus, for example, from the antigenic drift of antigenicity, influence of the seasonal influenza vaccine strains and popular strain compatibility, broad-spectrum flu vaccine development train of thought, etc. summarizes the progress of relevant research, to deepen the understanding of the influenza virus antigenic evolution, provide reference for flu vaccine development in the future.

Objective: To discuss the characteristics of symptoms improvement based on the follow-up evaluation of Eustachian tube balloon dilation medium to long-term efficacy in patients with symptomatic Eustachian tube dysfunction (SETD). Methods: Patients from 2015 to 2017 were followed up after Eustachian tube balloon dilation (with the sense of aural fullness, or tinnitus and hearing ambiguity). All participants had been done ETDQ-7 before surgery and were re-evaluated with ETDQ-7 in follow-up. The improvement of overall and individual symptoms scores in ETDQ-7, the effects of gender and the difference of scores at different stages (12-18 months, 18-24 months and 24-30 months) after the operation were analyzed. Results: There were 29 patients, including 16 males and 13 females, whose age ranged from 20 to 62 years old. The medium to long-term score of ETDQ-7 significantly declined after surgery (27.0±7.9 vs. 14.1±7.5, P<0.05). Among all symptoms, symptoms like "blockage feeling in ear or being like under the water, constriction feeling" , "sound of blisters or explosions in the ear" decreased obviously (P<0.05). Comparing different stages after surgery, the scores of ETDQ-7 existed no difference (P>0.05). And the difference of gender showed no significant influence on surgery effects. Conclusion The subjective symptoms of patients with Eustachian tube dysfunction diagnosed with SETD can be significantly improved in the medium to long-term follow-up after Eustachian tube balloon dilation, and the degree of improvement is not linearly related to the postoperative time.

With the increase of obesity and type 2 diabetes, gestational diabetes mellitus (GDM) is growing public health problem worldwide. GDM is one of the most ubiquitous diseases affecting pregnancy outcomes in perinatal women, which increases the incidence of adverse outcomes such as miscarriage, macrosomia, premature birth and stillbirth. Non-coding RNA (ncRNA) plays an important role in regulating the occurrence and development of GDM, and it is also related to the occurrence of complications of GDM. NcRNA is a type of RNA that don't encode proteins, including long non-coding RNA (LncRNA), microRNA (miRNA) and circular RNA (circRNA). More and more studies show ncRNA contains abundant information. This review discusses the relationship between three kinds of ncRNA and GDM, in aim to provide theoretical basis for further research on gestational diabetes.

Objective: To understand sexual and reproductive health (SRH) knowledge and access to sexual health information among pupils in higher grades, and to provide the scientific basis for conducting sexual education in family and school. Methods: A total of 1 098 pupils in grade four and five from 4 primary schools in a county, Jiaxing City, Zhejiang Province were selected for an anonymous computer assisted self-interview to get the information, including sexual and reproductive information and its sources, the condition about getting sexual education from school and family, and so on. Results: The percentage of correct answers about boy’s and girl’s puberty changes ranged from 15%~54%, and about reproduction and physiology ranges from 14%~70%. The awareness of private body parts ranged from 59%~98%. About 70%~95% could correctly identify sexual abuse scenes. The average score for knowledge on puberty changes, reproduction and physiology, identification of private body and identification of sexual abuse scenes was 31.89, 38.21, 77.03, and 85.72, with total average score of 58.21. In general, girls and students from urban areas or in grade five had higher knowledge level than boys and students from rural areas or in grade four did (P<0.05). Participants mainly obtained SRH knowledge from their mother(63.02%), father(40.53%) and teachers(27.50%). Girls and students from urban areas or in grade five reported higher proportion in access to information on human development, puberty development and health care, self-protection from parents and school teachers than boys and students from rural areas or in grade four(P<0.05). Conclusion Pupils in higher grades lacked SRH knowledge. It is necessary to raise awareness among school teachers and parents about the importance of providing sexuality education for pupils.

Objective To investigate the effect of Athos intelligent sportswear combined with MOTOmed intelligent sports training system for substituting partial artificial rehabilitation treatment on upper limb function and activities of daily living in the patients with stroke hemiplegia.Methods Forty-eight patients were randomly divided into the intelligent treatment group(IT) and conventional treatment(CT).The CT group adopted the routine rehabilitation treatment,and the IT group adopted the treatments of Athos intelligent sportswear combined with MOTOmed intelligent sports training system instead of passive motor training for upper extremities,flexion assistive motion training,flexion active anti-resistance training and antispasm exercise training by rehabilitation therapists.The correlation analysis between the biceps Lovett myodynamia testing results and Athos intelligent sportswear myodynamia testing results was conducted before treatment.The Fugl-Meyer assessment of upper extremity(FMA-UE) and Barthel index(BI) of activities of daily living(ADL) were assessed after 1-month and 3-month treatment.Results Thebiceps Lovett myodynamia testing results in 44 cases had significantly positive correlation with the Athos intelligent sportswear muscular strength monitoring results(r=0.929,P＜0.01).The FMA-UE and BI scores at 1,3 months of tratment in the two groups were all significantly increased compared with before tratment(P＜0.01).However,the intergroup difference after tratment was not statistically significant(P＞0.05).Conclusion Applying the Athos intelligent sportswear combined with MOTOmed movement therapy system for substituting partial manual tratment by rehebilitation therapist does not reduce the clinical effect and is conducive to alleviate the one-to-one manual training burden of rehabilitation therapists.
