Relationship between high blood pressure and body mass index, waist circumference, and waist-height ratio among children and adolescents in Suzhou / 中国学校卫生

@#To assess the relationship between high blood pressure (HBP) and body mass index (BMI), waist circumference (WC), and waist-height ratio (WHtR) among children and adolescents in Suzhou.@*Methods@#A total of 3 150 children and adolescents aged 7-17 years were enrolled through stratified cluster sampling from September to October, 2019. Questionnaire survey was conducted, and height, weight, WC and BP were measured to calculate BMI and WHtR, relationship of HBP and adiposity indicators were evaluated.@*Results@#The prevalence of HBP was 11.3%, overweight/obesity rate was 28.5%, and centrality obesity based on WC and WHtR was 20.6% and 23.7%, respectively. There were significant relationships between HBP and BMI, WC, and WHtR (χ2=157.80,105.87,124.17,P<0.01). As Logistic regression showed, compared to normal weight group, overweight/obesity based on BMI had positive relation with HBP (OR=3.89, 95%CI=3.09-4.90); compared to normal WC/WHtR, centrality obesity showed positive association with HBP (WC: OR=3.05, 95%CI=2.41-3.86; WHtR: OR=3.35, 95%CI=2.67-4.21). Meanwhile, BMI had joint effects on HBP with WC/WHtR. Specifically subjects with overweight/obesity and center obesity had higher risk of HBP, compared to normal BMI and WC subjects(OR=4.28, 95%CI=3.31-5.53).@*Conclusion@#Significant relationships between HBP and BMI, WC, and WHtR were found. BMI had joint effects on HBP with WC/WHtR. Keeping normal body weight and WC/ WHtR would have significant effects on HBP.

Research advances in endogenous neural stem cells promoting neural repair after ischemic stroke / 生理学报

Neural stem cell therapy, as a new therapeutic method for neural diseases, has aroused a wide concern for over 20 years since neural stem cells were first found in 1992. Ischemic stroke is highly concerned because of its high incidence, mortality and disability rates. Because the brain has a limited ability to repair itself, to improve neural function and promote neural regeneration may help to prevent occurrence and development of neurological diseases. It is noteworthy that some stroke patients showed an ability to repair brain several months after the stroke happened, suggesting an existence of endogenous nerve repair in these patients. The research advances in functions of endogenous neural stem cells in neural regeneration and the related regulators after ischemic stroke are summarized in this review to provide new views of the mechanism of neural functional recovery after ischemic stroke.

Influence of rehabilitation training based on action research method on exercise capacity and pulmonary function in patients with coronary heart disease / 心血管康复医学杂志

Objective :To explore effect of rehabilitation training based on action research method on exercise capacity and pulmonary function in patients with coronary heart disease (CHD).Methods :A total of 132 CHD patients trea-ted in our hospital were randomly and equally divided into routine rehabilitation group (received routine rehabilita-tion training) and action research group (received rehabilitation training based on action research method ) ,both groups were treated for 4 weeks.Pulmonary function indexes ,exercise capacity ,intensity of activity and quality of life (QOL) were compared between two groups after nursing .Results :Compared with routine rehabilitation group after nursing ,there were significant rise in all pulmonary function indexes , treadmill exercise slope [ (9.49 ± 3.76)% vs.(12.91 ± 3.49)%] ,6min walking distance [ (464.98 ± 87.43) m vs.(498.16 ± 93.56) m] ,walk speed [ (4.95 ± 1.30) km/h vs .(5.61 ± 1.12) km/h] ,questionnaire scores of exercise capacity [ (3.02 ± 0.65) scores vs . (4.66 ± 1.34) scores] ,questionnaire intensity of activity [ (3.73 ± 1.84) scores vs.(4.79 ± 1.25) scores] and QOL [ (7.75 ± 1.78) scores vs .(10.35 ± 0.61) scores] in action research group ,P＜0.05 or ＜0.01. Conclusion :Reha-bilitation training based on action research method helps to improve exercise capacity ,pulmonary function and quali-ty of life in patients with coronary heart disease ,which is worth extending .
