OBJECTIVES: To study the effect of parent-child cooperative music therapy on the core symptoms of children with autism spectrum disorder (ASD) and their mothers. METHODS: In this prospective study, 112 children with ASD and their mothers were divided into a music therapy group and an applied behavior analysis (ABA) group using a random number table (n=56 each). The children in the ABA group were treated with ABA, and those in the music therapy group were given parent-child cooperative music therapy in addition to the ABA treatment. The duration of intervention was 8 weeks for both groups. Childhood Autism Rating Scale (CARS), Autism Behavior Checklist (ABC), Parenting Stress Index-Short form (PSI-SF), Family APGAR Index, and Herth Hope Index (HHI) were used to evaluate the core symptoms of children with ASD and the parenting stress, family APGAR index, and hope level of mothers before and after intervention. RESULTS: A total of 100 child-mother dyads completed the whole study, with 50 child-mother dyads in each group. After intervention, the children in the music therapy group had significantly lower total score of ABC scale and scores of sensation, social interaction, and somatic movement, as well as a significantly lower total score of CARS than those in the ABA group (P<0.05). After intervention, compared with the mothers in the ABA group, the mothers in the music therapy group had significantly higher total score of PSI-SF and score of parent-child dysfunctional interaction, significantly higher total score of HHI and scores of each dimension, and significantly higher total score of APGAR and scores of cooperation and intimacy (P<0.05). CONCLUSIONS: Parent-child cooperative music therapy combined with ABA can alleviate the core symptoms of children with ASD, reduce the parenting stress of their mothers, and improve family APGAR index and hope level.

[Curative effect of progressively integrated sandplay therapy on core symptoms and sleep management in preschool children with mild-to-moderate autism spectrum disorder].

OBJECTIVE: To explore the curative effect of progressively integrated sandplay therapy on core symptoms and sleep management in preschool children with mild-to-moderate autism spectrum disorder (ASD). METHODS: A total of 50 mild-to-moderate ASD preschool children were randomly divided into an experimental group (n=25) and a control group (n=25). The control group was treated with structured teaching and auditory integration training (AIT). Based on these, the experimental group was treated with progressively integrated sandplay therapy. The Autism Behavior Checklist (ABC), Children Autism Rating Scale (CARS), Social Responsiveness Scale (SRS), Children's Sleep Habit Questionnaire (CSHQ) and emotion recognition tools were used to evaluate the overall curative effect before treatment and 3 months after treatment. RESULTS: The experimental group had significantly lower scores of feeling, social interaction, somatic motor, language factor, total ABC and total CARS than the control group (P<0.05). The experimental group had also significantly lower scores of social cognition, social communication, social motivation, autistic behavior factor and total SRS than the control group (P<0.05). The experimental group had a significantly higher accurate rate of recognition of the upper facial expression and lower facial expression than the control group (P<0.05). The experimental group had significantly lower scores of bedtime resistance, sleep onset, sleep duration, night waking, daytime sleepiness, and total CSHQ than the control group (P<0.05). The experimental group had significantly reduced themes of wounding and significantly increased themes of healing after sandplay therapy (P<0.05). CONCLUSIONS: Progressively integrated sandplay therapy can effectively improve the core symptoms and sleep quality of preschool children with mild-to-moderate ASD, which can be used as an early rehabilitation measure.

[Clinical efficacy of interactive group sandplay versus individual sandplay in the treatment of preschool children with autism spectrum disorder].

OBJECTIVE: To study the clinical efficacy of interactive group sandplay versus individual sandplay in the treatment of preschool children with autism spectrum disorder (ASD). METHODS: A total of 80 ASD children, aged 4-6 years, were enrolled and randomly divided into experimental and control groups, with 40 children in each group. The children in the experimental group joined group sandplay with normal children at a ratio of 1: 3, and those in the control group were treated with individual sandplay. The Aberrant Behavior Checklist (ABC) and Autism Treatment Evaluation Checklist (ATEC) were used to evaluate the treatment outcome after three months of intervention. RESULTS: There were 33 children in the experimental group and 28 in the control group. After three months of intervention, the experimental group had significant reductions in the scores of irritability, social withdrawal, and stereotypic behavior and the total score of the ABC scale (P<0.05), and the control group had significant reductions in the scores of behavior and inappropriate speech and the total score of the ABC scale (P<0.05). Compared with the control group, the experimental group had significantly greater improvements in the score of social withdrawal and the total score of the ABC scale after three months of intervention (P<0.05). After three months of intervention, the experimental group had significant reductions in the scores of sociability, sensory and cognitive awareness, and physical/health behavior and the total score of the ATEC scale (P<0.05), and the control group had significant reductions in the scores of speech, sociability, and physical/health behavior and the total score of the ATEC scale (P<0.05). Compared with the control group, the experimental group had significantly greater improvements in the scores of speech, sociability, and sensory and cognitive awareness and the total score of the ATEC scale after intervention (P<0.01). Compared with the control group, the experimental group also had significantly greater improvements in eye contact and sand stereotyped arrangement (P<0.05). CONCLUSIONS: Both interactive group sandplay and individual sandplay are effective in the treatment of ASD in preschool children. Interactive group sandplay is better than individual sandplay in the treatment of ASD, with significant improvements in sociability, emotion and stereotypic behavior.

[Clinical effect of integrated sandplay therapy in children with Asperger syndrome].

OBJECTIVE: To study the clinical effect of integrated sandplay therapy in preschool children with Asperger syndrome (AS). METHODS: A total of 44 preschool children with AS were randomly divided into an experimental group and a control group, with 22 children in each group. The children in the control group were given routine training, and those in the experimental group were given integrated sandplay therapy in addition to the routine training. The treatment response was assess by the Social Responsiveness Scale (SRS), emotional recognition tools and changes in sandplay theme characteristics after 6 months of treatment. RESULTS: Before intervention, there were no significant differences between the two groups in the total score of SRS, the score of each factor of SRS, and correct rates of facial expression recognition of the upright position, inverted position, upper face and lower face (P>0.05). After 6 months of intervention, both groups had significant reductions in the total score of SRS and the score of each factor of SRS (P<0.01); the control group had significant increases in the correct rates of facial expression recognition of all positions except the upright position (P<0.05), while the experimental group had significant increases in the correct rates of facial expression recognition of all positions (P<0.05). Compared with the control group after intervention, the experimental group had significantly lower total score of SRS and scores of all factors of SRS except social perception (P<0.01) and significantly higher correct rates of facial expression recognition of all positions (P<0.01). The experimental group had a significant change in the number of sandplay theme characteristics after intervention (P<0.01). CONCLUSIONS: Integrated sandplay therapy can improve social responsiveness and emotion recognition ability in preschool children with AS.

Seed structure characteristics to form ultrahigh oil content in rapeseed.

BACKGROUND: Rapeseed (Brassica napus L.) is an important oil crop in the world, and increasing its oil content is a major breeding goal. The studies on seed structure and characteristics of different oil content rapeseed could help us to understand the biological mechanism of lipid accumulation, and be helpful for rapeseed breeding. METHODOLOGY/PRINCIPAL FINDINGS: Here we report on the seed ultrastructure of an ultrahigh oil content rapeseed line YN171, whose oil content is 64.8%, and compared with other high and low oil content rapeseed lines. The results indicated that the cytoplasms of cotyledon, radicle, and aleuronic cells were completely filled with oil and protein bodies, and YN171 had a high oil body organelle to cell area ratio for all cell types. In the cotyledon cells, oil body organelles comprised 81% of the total cell area in YN171, but only 53 to 58% in three high oil content lines and 33 to 38% in three low oil content lines. The high oil body organelle to cotyledon cell area ratio and the cotyledon ratio in seed were the main reasons for the ultrahigh oil content of YN171. The correlation analysis indicated that oil content is significantly negatively correlated with protein content, but is not correlated with fatty acid composition. CONCLUSIONS/SIGNIFICANCE: Our results indicate that the oil content of YN171 could be enhanced by increasing the oil body organelle to cell ratio for some cell types. The oil body organelle to seed ratio significantly highly positively correlates with oil content, and could be used to predict seed oil content. Based on the structural analysis of different oil content rapeseed lines, we estimate the maximum of rapeseed oil content could reach 75%. Our results will help us to screen and identify high oil content lines in rapeseed breeding.

The BnGRF2 gene (GRF2-like gene from Brassica napus) enhances seed oil production through regulating cell number and plant photosynthesis.

Seed yield and oil content are two important agricultural characteristics in oil crop breeding, and a lot of functional gene research is being concentrated on increasing these factors. In this study, by differential gene expression analyses between rapeseed lines (zy036 and 51070) which exhibit different levels of seed oil production, BnGRF2 (Brassica napus growth-regulating factor 2-like gene) was identified in the high oil-producing line zy036. To elucidate the possible roles of BnGRF2 in seed oil production, the cDNA sequences of the rapeseed GRF2 gene were isolated. The Blastn result showed that rapeseed contained BnGRF2a/2b which were located in the A genome (A1 and A3) and C genome (C1 and C6), respectively, and the dominantly expressed gene BnGRF2a was chosen for transgenic research. Analysis of 35S-BnGRF2a transgenic Arabidopsis showed that overexpressed BnGRF2a resulted in an increase in seed oil production of >50%. Moreover, BnGRF2a also induced a >20% enlargement in extended leaves and >40% improvement in photosynthetic efficiency because of an increase in the chlorophyll content. Furthermore, transcriptome analyses indicated that some genes associated with cell proliferation, photosynthesis, and oil synthesis were up-regulated, which revealed that cell number and plant photosynthesis contributed to the increased seed weight and oil content. Because of less efficient self-fertilization induced by the longer pistil in the 35S-BnGRF2a transgenic line, Napin-BnGRF2a transgenic lines were further used to identify the function of BnGRF2, and the results showed that seed oil production also could increase >40% compared with the wild-type control. The results suggest that improvement to economically important characteristics in oil crops may be achieved by manipulation of the GRF2 expression level.

Maternal control of seed oil content in Brassica napus: the role of silique wall photosynthesis.

Seed oil content is an important agronomic trait in rapeseed. However, our understanding of the regulatory processes controlling oil accumulation is still limited. Using two rapeseed lines (zy036 and 51070) with contrasting oil content, we found that maternal genotype greatly affects seed oil content. Genetic and physiological evidence indicated that difference in the local and tissue-specific photosynthetic activity in the silique wall (a maternal tissue) was responsible for the different seed oil contents. This effect was mimicked by in planta manipulation of silique wall photosynthesis. Furthermore, the starch content and expression of the important lipid synthesis regulatory gene WRINKLED1 in developing seeds were linked with silique wall photosynthetic activity. 454 pyrosequencing was performed to explore the possible molecular mechanism for the difference in silique wall photosynthesis between zy036 and 51070. Interestingly, the results suggested that photosynthesis-related genes were over-represented in both total silique wall expressed genes and genes that were differentially expressed between genotypes. A potential regulatory mechanism for elevated photosynthesis in the zy036 silique wall is proposed on the basis of knowledge from Arabidopsis. Differentially expressed ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco)-related genes were used for further investigations. Oil content correlated closely with BnRBCS1A expression levels and Rubisco activities in the silique wall, but not in the leaf. Taken together, our results highlight an important role of silique wall photosynthesis in the regulation of seed oil content in terms of maternal effects.

[Qianlie Beixi Capsules for unliquefiable semen: a multi-center clinical study].

OBJECTIVE: To investigate the efficacy and possible action mechanism of Qianlie Beixi Capsules in the treatment of unliquefiable semen. METHODS: A total of 190 patients with unliquefiable semen were treated with Qianlie Beixi Capsules for 1 or 2 courses (3 weeks per a course). The seminal changes were observed and recorded. RESULTS: Of the 190 patients in the 1-course treatment arm, 99 were cured and 91 failed to respond after the first course. And the effectiveness rate was 52.1%. Of the 122 patients in the 2-course treatment arm, 81 were cured and 41 failed to respond after the second course. And the effectiveness rate was 66.4%. The efficacy of 2-course regimen was obviously better than that of 1-course regiment. In the meantime, sperm density improved in the 2-course treatment arm. Sperm motility improved slightly in the effective subjects of 1-course treatment arm. All the above results had statistically significant differences (P < 0.05). CONCLUSION: Qianlie Beixi Capsules is both safe and effective for unliquefiable semen and may shorten the time of seminal liquefaction.
