Intellectual characteristics of children with attention deficit hyperactivity disorder and developmental dyslexia / 中国当代儿科杂志

OBJECTIVE@#To study the intellectual characteristics of children with attention deficit hyperactivity disorder (ADHD) and developmental dyslexia (DD).@*METHODS@#A total of 55 children with ADHD and DD (ADHD+DD group), 150 children with ADHD alone (ADHD group), and 22 children with DD alone (DD group) were enrolled as subjects. Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) was used to evaluate and compare intellectual characteristics among the three groups.@*RESULTS@#There were significant differences in the scores of full-scale intelligence quotient (FSIQ), verbal comprehension index, perceptual reasoning index, and working memory index among the three groups (@*CONCLUSIONS@#Compared with the children with ADHD alone, the children with ADHD and DD have more severe impairment of FSIQ, verbal comprehension, perceptual reasoning, and working memory, and therefore, it is suggested to enhance the training on similarities, vocabulary, matrix reasoning, picture concepts, and recitation for children with ADHD and DD in clinical practice.

Novel exploration of cathartic pharmacology induced by rhubarb / 中国中药杂志

Rhubarb is well-known for its cathartic effect, and this cathartic effect, which is closely correlated with "whter" of traditional Chinese medicine (TCM), is brought into play in colon. Recent researches about the relation between formation and effects have identified that the anthraquinone glycosides with 1,8-dio-hydroxy and without hydroxyl in the 2, 3, 6, 7 location, such as emodin, rhein, chrysophanol, et al, can bring about fairly obvious effects of "Watery Diarrhea". Aquaporins (AQPs) are expressed abundantly in colonic epithelial cells, and the abnormal expression of AQPs can lead to the less absorption of water in colon and/or the more secretion of intestinal juice, which suggest that AQPs might be one kind of the effector molecules, which some drugs playing pharmacologic actions in colon depend on. This assumption provides a novel field of vision. Is this "Watery Diarrhea" effect induced by rhubarb concerned with the location alteration or the expression change of AQPs. We deduce that the regulative effects of AQPs by rhubarb in colon might provide a new pharmacologic explation about the cathartic effect through the exploration of TCM and Chinese herbal drugs, with TCM theory and the analysis of data about efficiency and pharmacologic researches of rhubarb and the researches of AQPs. This deduction might be used to reveal why rhubarb can bring about multi-efficiency.
