Objective To investigate the retrieval mechanism of prospective memory,spatiotemporal patterns of event-related potentials (ERP) were used to reveal neural correlates of the prospective interference effect. Methods A task of matching two sequential patterns was taken as the ongoing task and the detection of patterns with two salient levels as prospective memory tasks. Experiments were performed in blocks for single ongoing task block and two prospective memory blocks. Results No significant behavioral effect was found for prospective interference [reaction time(ms):control blocks 750.29±161.33,high salience blocks 770.94±174.89,low salience bocks 764.79±174.12,F(1.52,25.82)=0.48,P =0.57 and correction rate(%):control blocks 85.89±8.07,high salience blocks 88.26±7.00,low salience blocks 87.91±7.28,F(1.50,25.57)=2.46,P =0.12].But significant ERP effect was found at bilateral frontal regions from 160 ms to 240 ms for both two prospective memory blocks. Moreover,greater negativity at the right frontal polar region appeared significantly at 360'440 ms for higher salient patterns. Conclusion Prospective memory is retrieved based on strategic monitoring and high salient stimuli may enhance to keep the prospective goal and improve task switching.

Functional constipation(FC) in childhood is characterized by a low defecation frequency in combination with either involuntary loss of stools(encopresis),passage of large amounts of stool,retentive posturing,or hard and often painful defecation.It represents 3%-5% of general pediatric outpatient visits and up to 25% of pediatric gastroenterology consultations.FC is a diagnosis made by history and physical examination.No testing is necessary or desirable.The decision to seek medical care for symptoms arises from a parent′s or caretaker′s concern for children.The caretaker′s threshold for concern varies with his or her experiences and expectations,coping style,and perception of illness,till now there is not an universal native criteria established in spite of much has been done in it.The criteria used are still to draw assistance from the foreign standard,among which the classic criteria,the Rome Ⅱ and Rome Ⅲ criteria are considered commonly used.The purpose of this paper is to descript the several foreign criteria,and to make comparison among them,and to explore their applicability and effectiveness in childhood FC

Objective To investigate the interventional effect of multidimensional strategy to reduce the incidence of neonatal ventilator-associated pneumonia.Methods The patients who were admitted to the NICU department and received mechanical ventilation (MV) for more than 48 hours from October 2012 to September 2014 were recruited. The control group received the experienced interventions from October 2012 to September 2013, neonates from October 2013 to September 2014 were recruited as the intervention group receiving multidimensional controlling strategy, including bundle care, education, pro-cess and outcome surveillance and feedback on the practices. The compliance of before-after implementation of interventions were quantitatively evaluated,and the rate of VAP was compared between the two groups.Results The compliance rate of hand hygiene and the qualiifed rate of sputum suction, oral care, drain condensation from ventilator circuit, semi-recumbent posi-tion, and preventing of stress-ulcers were increased 17.0%, 11.4%, 14.7%, 18.2%, 37.5% and 56.3% respectively after implemen-tation of multidimensional strategy, and had statistical difference (χ2=36.47-294.36,P<0.01). But the qualiifed rate of antibiotic use only was 66.1% in the post-VAP bundle phases, and showed no statistical difference before and after(P>0.05). The VAP rate was 41.7 cases per 1000 MV-days during control group and 19.7 cases per 1000 MV-days during intervention group, had statis-tical signiifcance (P<0.05). But the rate of ventilator application showed no statistical difference between two group (P>0.05). ConclusionThe multidimensional strategy can effectively prevent the incidence of VAP.

Objective:To observe the effect of rapid point pressure on clinical effect and pulmonary function of patients with chronic persistent bronchial asthma.
Methods:A total of 60 confirmed chronic persistent bronchial asthma cases were randomly allocated into two groups, 30 in each group. Cases in the treatment group were treated with rapid point pressure, 1 h for the initial treatment, and 40 min for the ensuing treatments. The treatment was done once a day for 40 d. Cases in the control group were treated with Compound Methoxyphenamine Hydrochloride Capsules, 2 capsules for each dose, 3 times a day. The treatment lasted for 7 consecutive days. A 1-year follow-up was made for both groups.
Results:After treatment, the scores of each symptom and total symptom scores for the traditional Chinese medicine (TCM) symptoms in the treatment group were significantly higher than those in the control group (P<0.05);the total effective rates in the treatment group were higher than those in the control group in each time frame; and there was a between-group statistical significance in total effective rate after 7 d of treatment (P<0.01). After 40-day treatments, there were statistical significances in the forced expiratory volume in 1 s percentage of predicted value (FEV 1%) and inspiratory capacity (IC%) in the treatment group (P<0.05); however, there were no statistical significances (P>0.05) in forced expiratory volume in 1 second to forced vital capacity ratio (FEV1/FVC), peak expiratory flow rate (PEF%) and maximum midexpiratory flow rate (MMEF%); and there were no statistical significances in pulmonary function parameters in the control group. In addition, as for pulmonary function parameters, there were no intra-group statistical significances in differences before and after treatment (P>0.05).
Conclusion:Rapid point pressure can alleviate patients’ TCM symptoms and improve their FEV%and IC%.

Objectives: To assess the feasibility and stability of right ventricular outflow tract (ROVT) pacing under current technology by comparing the results of ROVT pacing with the traditional right ventricular apex (RVA) pacing. Methods: A total of 42 patients (at mean age of 63.5±10.4 years) without structural heart disease were randomly divided into two groups. RVA pacing group (n=14),and RVOT pacing group(n=28). An active fixation lead was implanted in all patients whose pacemaker could automatically measure the pacing threshold every day. The operation time,X-ray exposure time and lead parameters detected during the operation were collected to evaluate the feasibility of RVOT pacing. The complications related to lead and implantation procedure and the trend of threshold change during the follow-up time were used to assess the stability of RVOT pacing.Results: There were no statistic differences between RVA pacing group and RVOT pacing group in terms of operation time,X-ray exposure time and lead parameters. In RVOT group,the change of threshold during acute period was similar to those in RVA group (P=0.23). Chronic pacing threshold was also comparable between two groups,mean threshold at 6 months follow-up time was 0.55±0.11V and 0.54±0.09V at 0.4 pulse width in RVA group and RVOT group respectively (P=0.787).Conclusion: RVOT pacing was feasible and stable in operation time and lead characteristics compared with the conventional RVA pacing under current pacing technology.
