Mindfulness-based cognitive therapy is associated with distinct resting-state neural patterns in patients with generalized anxiety disorder.

Introduction: Mindfulness-based cognitive therapy (MBCT) may be effective for generalized anxiety disorder (GAD); however, the neural mechanism is poorly understood. In this study, we examined the potential neural mechanisms through which MBCT may reduce anxiety in patients with mild-to-moderate GAD.

Methods: Eight weekly group MBCT sessions (2 h each) were conducted with 32 GAD patients.

[Effect of parent training in combination with methylphenidate treatment on family relationships for children with attention deficit/hyperactivity disorder].

Objective: To investigate the effect of parent training combined with methylphenidate treatment on family relationships in children with attention deficit/hyperactivity disorder (ADHD).

Methods: Fifty-nine parents of children with ADHD under methylphenidate treatment participated in a modified 5-week training program. The intervention effect was evaluated using the Conners Parent Symptom Questionnaire, ADHD Rating Scale-IV Home Version (ADHD-RS-IV Home Version), Caregiver Strain Questionnaire, Parent-Child Relationship Self-rating Scale and Piers-Harris Children's Self-Concept Scale.

[Study on attention-deficit hyperactivity disorder in children based on resting-state functional magnetic resonance imaging].

Objective: To compare resting-state functional magnetic resonance imaging (fMRI) findings of children with attention-deficit hyperactivity disorder (ADHD) and normal children, and to investigate the possible mechanism of brain dysfunction in children with ADHD.

Methods: Resting-state fMRI was performed on 18 children who met the DSM-IV diagnostic criteria for ADHD (ADHD group) and 18 normal children (control group) matched for age, sex, IQ, degree of education and handedness. The two groups were compared in terms of amplitude of low frequency fluctuation (ALFF) and regional homogeneity (ReHo).

[Influential factors for methylphenidate treatment compliance in children with attention deficit hyperactivity disorder].

Objective: To investigate influential factors for the tendency to medicate and medication compliance in children with attention deficit hyperactivity disorder (ADHD).

Methods: A total of 188 children aged from 5 to 16 years, who were initially diagnosed with ADHD according to DSM-IV criteria, were included in the study. They underwent symptom assessment and cognitive function test.

[Leaf morphological structure and physiological and biochemical characteristics of female and male Hippophae rhamnoides subsp. sinensis under different soil moisture condition].

A field experiment was conducted to study the leaf morphological structure and physiological and biochemical characteristics of female and male Hippophae rhamnoides subsp. sinensis under different soil moisture condition. When the soil moisture condition was poorer, the leaf structure of the plants displayed distinct xeromorphic characteristics, being more obvious for the female plants.

Control of diesel soot and NOx emissions with a particulate trap and EGR.

The exhaust gas recirculation (EGR), coupled with a high-collection efficiency particulate trap to simultaneously control smoke and NOx emissions from diesel engines were studied. This ceramic trap developed previously provided the soot cleaning efficiency of 99%, the regeneration efficiency reaches 80% and the ratio of success reaches 97%, which make EGR used in diesel possible. At the presence of EGR, opening of the regeneration control valve of the trap was over again optimized to compensate for the decrease of the oxygen concentration in the exhaust gas resulted from EGR.
