Objective Even after successful surgical repair,patients with coarctation of the aorta (CoA) are at high risk of long-term morbidity and mortality due to cardiovascular events,which is probably related to persistent arterial disfunction during long-terr follow-up after operation,The aim of the study was to explore the alterations of vascular structure and function in children with successfully repaired CoA in the short-and mid-term follow-up.Methods A cohort of 20 children who underwent CoA repair between January 2010 and October 2010 in Guangzhou women and children's Medical Center was studied.There were 14 males and 6 females in CoA group,which comprised 6 patients with isolated CoA,14 patients with CoA associated with intracardia anomalies,whose median age of operation was 4 months (rang from lmonth to 10.0 years).And 20 patients with isolated ventricular septal defect (VSD) were included as VSD group during the same time,with 12 males and 8 females,whose median age of operation was 5 months (rang from 1 month to 12.0 years).Resting blood pressure,flow-mediated dilation (FMD) of the brachial artery,carotid intima-media thickness (IMT) were compared in CoA group and VSD group,including preoperative media data and follow-up of 1 month,6 months and 1 year.In addition,as comparison to the operation group,20 health children with normal echocardiographic findings,whose median age was 5 months (rang from 3 month to 10.0 years),were selected as health group for the 1-year following up.None of them had obesity,hyperlipidemia,diabetes mellitus,metabolic diseases or systemic inflammatory disease.Results As a result of the datas before operation and those I month,6 months and 1 year after operation,all children were normotensive at rest.In the same period,Carotid IMT in CoA group[(0.47 ± 0.10)mm,(0.49 ±0.10) mm,(0.57 ±0.07)mm,(0.61 ± 0.07) mm]was significantly thicker than that in VSD group[(0.41 ±0.11) mm,(0.43 ±0.11)mm,(0.51 ±0.08) mm,(0.55 ±0.08) mm](P<0.05) and health group[(0.40 ±0.09) mm,(0.42 ±0.11)mm,(0.50 ±0.08) mm,(0.57 ±0.08) mm](P <0.05),Brachial artery FMI in children with CoA[(5.4,6 ±1.51)%,(5.71 ±1.88)%,(5.42±1.69)%,(5.27±1.02)%]was significantly lower than that in the VSD control group[(6.69±1.45) %,(6.66±1.21)%,(6.81 ±1.03)%,(6.43±1.34)%](P<0.05) and health group[(6.59 ±1.84)%,(6.84±1.41)%,(6.91 ±1.31)%,(6.56±1.62)%](P<0.05).Significant difference could not be found in neither the IMT nor the FMI between the VSI control group and health group in 4 period respectively,P > 0.05.Conclusion Children after successful coarctation repair have abnomal structural and functional properties of the aorta above the place of coarctation even their blood pressure at rest is normal.These results confirm that the alterations in mechanical properties of carotid arteries as well as the generalized endothelial dysfunction in children with coarctation of the aorta are persistent,which can not be prevented or reversed by surgical repair,and which may partly explain the high incidence of cardiovascular disease observed in their adulthood and reduced life expectancy,furtherly supporting the claim that coartation of the aorta is a systemic vascular disorder which needs long-term follow-up of vascular function.

Objective:
To investigate the daily learning time status of elementary school students and understand the implementation of Health Requirements of Daily Learning Time for Secondary and Elementary School Students (GB/T 17223-2012) in schools, so as to provide a reference for strengthening and improving school health and health education in the new era.
Methods:
A stratified cluster random sampling method was used to select 7 776 primary school students in Shandong Province, and a survey questionnaire was designed based on the Health Requirements for Dayily Learning Time for Secondary and Elementary School Students(GB/T 17223-2012) standard to investigate their daily learning arrangements, sleep and physical activities, and breaks between classes. Comparison of intergroup differences were used by Chi square test and Kruskal-Wallis H test.
Results:
About 55.88 % of primary school students for daily learning time met the standard. There was a statistically significant difference in the daily learning time achievement rate among primary school students in three grades for first and second grade, third and fourth grade and fifth and sixth grade ( Z=1 629.47, P <0.01), and the fifth and sixth grade had the highest proportion of achieving the standard (85.92%). Specifically, the proportions of students whose class hours, class numbers and morning reading time meeting the standards were 30.07%, 10.20% and 42.19%, respectively. The sleep deficiency rate of primary school studnets was 58.69%, and the physical activity deficiency rate was 65.78%; and there was a statistically significant difference in the rate of insufficient sleep time and physical activity time among primary school students of different grades ( χ 2=56.39, 95.95, P <0.01), with sixth grade students showing the highest rates for both sleep and physical activity deficiencies (64.35%, 73.37%). Additionally, 49.78% of students had recess time below the standard requirements.
Conclusion
The health status of daily learning time among primary school students in Shandong Province is poor, with insufficient implementation of school standards, and the implementation of standards needs to be further strengthened.

Objective:To monitor the blood pressure in pediatric patients with coarctation of the aorta (CoA) before and 8 years after surgery, and explore the mechanism of elevated blood pressure in pediatric patients with repaired CoA.Methods:A cohort of 23 pediatric patients who underwent CoA repair between January 2010 and October 2010 in Guangzhou Women and Children's Medical Center was studied. And 20 age-, sex-match patients with isolated ventricular septal defect (VSD) who underwent surgery at the same time, 20 age-, sex-match health patients with normal echocardiographic findings were included in the study. Systolic blood pressure (SBP), diastolic blood pressure (DBP), arm-leg SBP gradient, right carotid intima-media thickness (CIMT), serum transforming growth factor-β1 (TGF-β1) were monitored at baseline(1 day before surgery) and 8-year follow-up (8 years after surgery).Results:There were no differences in SBP and DBP among patients with CoA, patients with VSD and health children at baseline ( P>0.05). But at 8-year follow-up, 2 patients with CoA exhibited hypertension. Not only that, patients with CoA had higher SBP than patients with VSD and health children at 8-year follow-up ( P<0.05). Patients with CoA had higher arm-leg SBP gradient than patients with VSD and health children at baseline ( P<0.01). But there were no differences in arm-leg SBP among patients with CoA, patients with VSD and health children at 8-year follow-up ( P>0.05). Patients with CoA had increased CIMT and higher serum levels of TGF-β1 at baseline and 8-year follow-up ( P<0.05). The preoperative levels of CIMT and serum TGF-β1 in the patients with CoA were highly positively correlated with their levels at 8-year follow-up, respectively ( P<0.01). There was a strong correlation between the levels of CIMT and serum TGF-β1 in patients with CoA, both preoperatively and postoperatively ( P<0.01). The preoperative and postoperative levels of CIMT and serum TGF-β1 in the patients with CoA were highly positively correlated with SBP at 8-year follow-up, respectively( P<0.05). Conclusion:Although surgery can successfully cure the anatomical " stenosis" , patients with CoA have elevated systolic blood pressure than normal people and patients with simple congenital heart disease (such as VSD). And some of the patients with CoA suffer from hypertension at long-term follow-up, even they are normotensive preoperatively. It may be related to vascular remodeling, in which TGF-β signaling pathway may be involved. Monitoring CIMT and TGF-β1 in patients with CoA preoperatively may be significative for prediction for the levels of SBP postoperatively.

Objective:To evaluate the effects of remazolam on sublingual microcirculation during anesthesia induction in the patients undergoing off-pump coronary artery bypass grafting under general anesthesia.Methods:Forty-two patients of both sexes, of American Society of Anesthesiologists Physical Status classification Ⅲ or IV, aged 45-75 yr, with body mass index of 18-30 kg/m 2, undergoing off-pump coronary artery bypass grafting under total intravenous anesthesia, were divided into 2 groups ( n=21 each) using a random number table method: propofol group (group P) and remazolam group (group R).Remazolam 0.15-0.35 mg/kg was intravenously infused in group R, and propofol 1.5-2.0 mg/kg was intravenously infused in group P, when patients lost consciousness and they did not response to shoulder tapping, the maintenance dose was adjusted as follows: remazolam 0.15-0.30 mg·kg -1·h -1 in group R and propofol 2.0-4.0 mg·kg -1·h -1 in group P. The BIS value was maintained at 45-55 during operation in the two groups.The proportion of perfused vessels for all vessels (PPV (all)), proportion of perfused small vessels (PPV (small)), perfused vessel density of all vessels (PVD (all)), and perfused small vessel density (PVD (small)) were recorded before induction (T 1), immediately after intubation (T 2) and 30 min after intubation (T 3).The cardiovascular events were recorded during anesthesia induction. Results:Compared with the baseline at T 1, PPV (all), PPV (small) and PVD (all) were significantly decreased at T 3 ( P<0.05), and no significant change was found in PPV (all), PPV (small), PVD (all) and PVD (small) at T 2 in group P ( P>0.05), and no significant change was found in PPV (all), PPV (small), PVD (all) and PVD (small) at T 2 and T 3 in group R ( P>0.05).Compared with group R, PPV (small) was significantly decreased at T 3 in group P ( P<0.01). Conclusions:Remazolam exerts less inhibitory effect on sublingual microcirculation than propofol during anesthesia induction in the patients undergoing off-pump coronary artery bypass grafting.
