Objective To investigate the influence of parental compliance on the therapeutic effect of children with epilepsy.Methods Two hundred and sixty children with epilepsy and their parents admitted to the First People's Hospital of Wenling from December 2013 to June 2016 were enrolled,and the classical Morisky medication adherence questionnaire (MMAS-8) was applied to evaluate the compliance of parents for treatment of their children with epilepsy;after the patient taking drug for 3 days,fasting venous blood was collected in the morning,the concentration of the blood drug was tested and the influence of parent compliance on the blood drug concentration of the child with epilepsy was evaluated.Results In 260 patients,122 cases took karma form,and 138 cases took valproate orally.There were parents with good medication compliance in 130 cases (50％),medium medication compliance 80 cases (30.76％) and poor adherence to the doctor order in 50 cases (19.23％).In cases using medication irregularly,there were 26 cases sometimes without taking any drug (10.0％),17 patients' medication being interrupted (6.54％) and 10 cases having excessive medication (3.85％);no relationships were found between parental compliance and each of the following items,family role,occupation and age (all P ＞ 0.05);and the compliance was related to gender,indicating that women's good compliance level was higher than that of males';the education level was positively proportional to the compliance,and the compliance of parents with senior high school or above degree was higher than those with primary school and junior secondary school levels (83 cases vs.9 cases,38 cases,both P ＜ 0.01).Under situation of parents with poor compliance,their children had blood drug concentration higher or lower than proper range of drug level (high in 22 cases,low in 41 cases,higher than the result in good compliance 0 cases and 17 cases respectively),thus seriously affected the safety and efficacy of the treatment;the patients' frequency of irregular medication in parents' good compliance group was significantly lower than that in parents' poor compliance group [3.08％ (4/130) vs.72.0％ (36/50),P ＜ 0.05].Conclusion To improve the therapeutic effect of epileptic children,their parental good cooperation is necessary.

Objective To assess the reproducibility of contrast-enhanced echocardiography and conventional echocardiography for measurements of left ventricular ejection fraction(LVEF) and left ventricular volume in patients undergoing cancer chemotherapy. Methods One hundred and two patients undergoing cancer chemotherapy were divided into satisfactory image group(36 subjects) and unsatisfactory image group(66 subjects) according to the quality of the recorded images.High frame rate two-dimensional and three-dimensional images were recorded from apical long-axis view,four-chamber view and two-chamber view of left ventricle. Contrast-enhanced echocardiography was performed in the unsatisfactory image group.Two equally experienced examiners measured the LVEF and left ventricular volume in all patients by EchoPac software. Results The reproducibilities of Simpson′s biplane method and 3D full-volume echocardiography were low for measurements of LVEF in unsatisfactory image group ( P < 0.01).But they were improved significantly with contrast-enhanced echocardiography ( P > 0.05 ). The reproducibilities of Simpson′s biplane method and 3D full-volume echocardiography for measurements of left ventricular end-diastolic volume in unsatisfactory image group were also improved by performing contrast-enhanced echocardiography ( P > 0.05). The reproducibilities for measurements of left ventricular end-systolic volume were well in both group.Conclusions The reproducibilities for measurements of LVEF and left ventricular volume are improved in patients undergoing cancer chemotherapy with unsatisfactory images by using contrast-enhanced echocardiography.

Objective To explore the effects of adenosine stress on myocardial strain in healthy mice by speckle tracking imaging (STI).Methods A high-resolution rodent ultrasound machine Vevo 2100 was used to perform conventional transthoracic echocardiography at baseline and after intravenous infusion of adenosine in 34 C57BL/6 mice.Echocardiography images from standardized parasternal long axis and short axis at papillary muscle level were consecutively acquired in real-time.All dynamic images were recorded for off-line analysis.Left ventricular myocardial mechanical strain parameters were acquired both under resting status and during adenosine stress.Results Thirty-four experimental animals successfully underwent STI before and during adenosine stress. There was no significant difference in heart rate,left ventricular structure and functional parameters between before and after the adenosine stress ( P >0.05).Global peak longitudinal strain value in left ventricular long-axis view was significantly increased during stress compared with those at resting status ( P < 0.05);while there was no significant increase in the global peak circumferential strain and global peak radial strain values in short-axis view at papillary muscle ( P >0.05).Conclusions Myocardial strain is obtained in healthy mice before and after adenosine stress.This provides an evidence to the application of stress echocardiography in mice with coronary heart disease or other cardiovascular disease in the future.

Objective To explore the effects of adenosine stress on myocardial perfusion in healthy mice by myocardial contrast echocardiography ( MCE) . Methods MCE was carried out to quantify regional myocardial perfusion at rest and during adenosine stress using a VEVO 2100 system in 26 C57BL/6 mice . Echocardiography images from standardized parasternal long axis and short axis at papillary muscle level were consecutively acquired in real‐time . All dynamic images were recorded for off‐line analysis . Left ventricular myocardial perfusion quantitative parameters were acquired both under resting status and during adenosine stress . Replenishment curves of myocardial contrast were obtained and myocardial blood flow ( MBF) was calculated . Results Twenty‐six experimental animals successfully underwent MCE before and during adenosine stress . T here was no significant difference in heart rate ,left ventricular structure and functional parameters before and during adenosine stress ( all P ＞0 .05) . Rates of signal rise β values which were used to estimate blood velocity of middle anterior septum and posterior wall in left ventricular long‐axis view and anterior wall ,lateral wall ,inferior wall and septal wall in short‐axis view at papillary muscle increased significantly during stress compared with those at rest ( all P ＜0 .05 ) . T here was no significant difference in the plateau intensity A values( all P ＞0 .05 ) . T he MBF in each segment of the myocardium increased significantly during stress compared with those in resting state ( all P ＜0 .05) . Conclusions T he physiological characteristics of myocardial perfusion in mice before and during adenosine stress were preliminarily obtained ,w hich provided a basis for the application of adenosine stress echocardiography in cardiovascular disease models such as coronary heart disease in mice .
