Objective:To study the epidemiology of attention-deficit hyperactivity disorder(ADHD) in pupils of Zhenjiang urban districts. Methods: Questionnaire was designed and employed for parents of 3 698 pupils at schools in Zhenjiang urban districts. ADHD was diagnosed according to the international DSM-Ⅳ scale. Differences were determined by Qi-square test and multiple regression analysis. Results: Prevalence of ADHD was 6.54% in pupils of Zhenjiang urban districts, and was 9.14% in male pupils and 4.01% in female. There was significant difference between 2 gender groups (? 2=34.933,P

This study was aimed to investigate the effects of high-dose strictosamide injection on cardiovascular sys-tem of anesthetized beagle dogs and to examine the inhibition of strictosamide on ion channels in vitro. Indexes such as changes of systolic blood pressure (Sys), diastolic blood pressure (Dia), mean blood pressure (MBP), heart rate (HR), PR, QRS, QT, QTcb and QTcv at different time points before and after strictosamide injection in dogs were monitored by the polygraph system. The inhibition of strictosamide at different concentrations on hERG potassium channel in CHO-hERG cells and Nav1.5 sodium channel in HEK-293-Nav1.5 cells were measured by whole-cell patch-clamp method. The results showed that compared with the blank control group, Sys, Dia, MBP and HR were obviously declined 15 min after medication in the strictosamide (60, 18 mg·kg-1) group and the vehicle-control group (containing tween-80) (P < 0.05). After medication, all indexes were recovered. Compared to the vehicle-control group, there were no significant differences at different time points in each medication groups. Compared with the blank control group and before medication, the QT interval, QTcb and QTcv were significantly prolonged 15 min af-ter medication in the strictosamide (60, 18, 6 mg·kg-1) group and the vehicle-control group (P< 0.05). When medi-cation stopped, indexes were recovered at certain level. Compared with the vehicle-control group, there were no sig-nificant differences of QT interval, QTcb and QTcv of each medication group at different time points (P> 0.05). The inhibition of strictosamide on hERG potassium channel and Nav1.5 sodium channel were weak with IC50 values of 560.8 μM and > 900 μM, respectively, which were far greater than the positive controls. It was concluded that sin-gle, high-dose intravenous injection of strictosamide may lead to a lower blood pressure, a slower heart rate and a prolongation on the QT interval in beagle dogs, which returned to basal levels when medication stopped. It was spec-ulated that the reduction of blood pressure and the slowing of heart rate were related to tween-80 contained in the vehicle control group. No significant inhibitory effects were detected on hERG potassium channel and Nav1.5 sodium channel in vitro, which suggested that other mechanisms may be involved in strictosamide-induced QT interval pro-longation in animals.

Objective:The present study was designed to test the hypothesis that inflammation is involved in the end-organ damage(EOD) induced by sinoaortic denervation(SAD) in rats.Method:SAD was performed in male Sprague-Dawley rats at the age of 10 weeks.Under anaesthesia,aortic nerves were cut and the sinus region of the carotid artery was stripped and painted with 10% phenol.Pathological evaluation of EOD and the determination of plasma or tissue levels of the factors related to inflammation,including thromboxane B2(TXB2) interleukin-1(IL-1),tumour necrosis factor α(TNF-α) and reactive oxygen species(ROS) were performed at 16 weeks after SAD.Pathological evaluation of EOD included heart weigh ratio,myocardial and blood vessel hydroxyproline and collagen volume fraction,glomerular injury score and number of infiltrating inflammatory cells.Indomethacin(20 mg/kg per day,orally) or vitamin E(100 mg/kg per day,orally) was administered for 12 weeks,beginning from4 weeks after SAD,to observe their effects on SAD-induced EOD.Results:There were significant fibrosis and inflammatory infiltration in the myocardium and blood vessels,represented by higher hydroxyproline and collagen volume fraction,and a large amount of inflammatory cells in the tissues of SAD rats.Heart weight and kidney glomerular injury score were significantly higher in ed significantly after SAD.Indomethacin and vitamin E significantly decreased the contents of some factors related to inflammation in SAD rats.Both drugs also alleviated myocardial and vessel fibrosis,inflammatory infiltration and kidney damage.Conclusion:Inflammation is involved in the organ damage induced by SAD in rats.

Objective To observe the mechanisms that Xiaoyao powder influences the hypothalamus-pituitary-adrenal (HPA) axis of chronic-stress rats. Methods Chronic stress rats were as researching object,and RU-38486 acted as tool drugs. The serum-GC density of rats were tested with ELISA,and the glucocortcoid(GR) in hippocampus neuron were tested with immunofluorescence,the CRH mRNA in hypothalamus were tested by in situ hybridization (ISH). Results Compared with normal group ( 1.09 ± 0.11 ;0.57 ± 0.10), the expression of GR in hippocampus of model group decreased(0.65 ± 0. 10; P ＜ 0. 01 ), and the expression of CRH mRNA in hypothalamus of model group increased ( 1.12 ±0. 11; P＜0. 0l ) ,the GR in hippocampus of RU-38486 group increased ( 1.59 ± 0. 11; P ＜ 0. 01 ), and the expression of CRH mRNA in hypothalamus of RU-38486 group reduced (0.48±0.10; P＜0.05) ,but both the expression of GR in hippocampus and the CRH mRNA in hypothalamus of Xiaoyao powder group were no change (0.62 ±0.08;0.97 ±0.13; P＞0.05). Compared with model group,both the expression of GR in hippocampus of RU-38486 and Xiaoyao powder group increased (P＜0. 01) ,and both the expression of CRH mRNA in hypothalamus of RU-38486 and Xiaoyao powder group reduced (P＜0.01). Conclusion Multi-stress can result in the expression of GR in hippocampus of rats decreasing and the expression of CRH mRNA in hypothalamus increasing, but those changes can be restrained by Xiaoyao powder, and it is the maybe mechanism of Xiaoyao Powder resisting chronic stress in HPA axis.
