Association between early life factors and cardiometabolic risk factors in children and adolescents / 中国学校卫生

Objective@#To understand the early life factors that influence cardiometabolic risk factors in children and adolescents, so as to provide effective measures to curb cardiometabolic risk factors such as hypertension and diabetes in children and adolescents.@*Methods@#Data were sourced from the 2020 follow up survey of the Xiamen Adolescent Development Cohort. The study involved 1 197 subjects for whom completed anthropometric examination and blood biochemistry testing data, as well as early life data. Early life and sociodemographic data were obtained through questionnaire surveys, while cardiometabolic indicator data were sourced through physical examinations and blood testing. Logistic regression analysis was performed to analyze the impact of early life factors on the cardiometabolic risk factors after adjusting for gender, age, and family history.@*Results@#The prevalence rate of cardiometabolic risk factors clustering in children and adolescents in Xiamen was 17.96%, with boys (26.67%) reporting higher rates than girls (9.64%), and the difference was statistically significant ( χ 2=57.69, P <0.01). For every additional early life risk factor, the risk factors of obesity increased 0.35 times ( OR=1.35, 95%CI=1.03-1.78, P <0.05). Post term pregnancy may be a primary early life risk factors for cardiometabolic risk factors, and it was associated with an increased risk of cardiometabolic risk factors clustering (OR=2.45, 95% CI =1.11-5.41) and high triglycerides ( OR=3.25, 95%CI =1.39-7.61)( P <0.05).@*Conclusion@#Increased cardiometabolic risk factors in youth is associated with early life adverse factors. It is crucial to pay greater attention to post term pregnancy as an early life factor and to consider obesity as a cardiometabolic risk factors. Controlling early life adverse factors is important for the prevention of cardiovascular disease.

Co-occurrence trend of overweight,obesity and elevated blood pressure and its association with lifestyle factors among students in Inner Mongolia Autonomous Region / 中国学校卫生

Objective@#To explore the epidemiological trend of overweight and obesity, elevated blood pressure and their comorbidities in children and adolescents from Inner Mongolia Autonomous Region during 2016-2021, and to analyze its association with lifestyle, so as to provide reference for formulating prevention and control strategies of regional common comorbidities in schools.@*Methods@#A total of 8 908, 8 222, 9 448, 127 068, 100 778, and 138 540 students aged 10-18 years in Inner Mongolia were selected by stratified random cluster sampling in September each year from 2016 to 2021. Physical examination and questionnaire survey were conducted on the included students. The prevalence trends of overweight，obesity, elevated blood pressure and their co-occurrence were analyzed. Logistic regression was used to compare the prevalence of elevated blood pressure in different body mass index (BMI) groups. After excluding individuals without lifestyle information in 2021, Logistic regression analysis was used on 136 374 subjects to analyze the association between overweight，obesity, elevated blood pressure and their co-occurrence and lifestyle factors.@*Results@#During 2016 to 2021, the prevalence of comorbidity of overweight, obesity with elevated blood pressure among students in Inner Mongolia Autonomous Region were 5.04%，5.14%，4.99%，7.51%，7.60% and 9.45%， respectively . The prevalence of overweight and obesity was 26.94%, 28.07%, 29.62%, 34.19%, 36.71% and 37.53%, respectively. The prevalence of elevated blood pressure were 16.05%, 11.54%, 13.12%, 14.85%, 14.12% and 18.40%, respectively. Except for 2016, the risk of elevated blood pressure in overweight and obese people was higher than that in normal BMI group in other years, and there was a positive correlation between overweight and obesity and elevated blood pressure after gender and urban and rural areas ( P < 0.05 ). In 2021, the detection rate of comorbidity of overweight and obesity with elevated blood pressure among children and adolescents in urban areas was higher than that in suburban counties, and the reporting rate of healthy lifestyle was lower than that in suburban counties ( P <0.05).Skipping breakfast ( OR =1.11，95% CI =1.07-1.16) and non daily moderate and high intensity physical activity( OR =1.27，95% CI =1.20-1.34) were positively correlated with the co-occurrence of overweight，obesity and elevated blood pressure among children and adolescents in Inner Mongolia Autonomous Region. Non daily moderate and high intensity physical activity ≥60 min was positively correlated with elevated blood pressure ( OR =1.11，95% CI =1.07-1.16), and insufficient sleep was positively correlated with overweight，obesity ( OR =1.04, 95% CI =1.01-1.06)（ P ＜0.05）.@*Conclusion@#The prevalence of overweight，obesity, elevated blood pressure and their co-occurrence among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Overweight/obesity is an important risk factor for elevated blood pressure, and unhealthy lifestyles are risk factors for co-occurrence of overweight，obesity and elevated blood pressure. Region specific lifestyle interventions are indispensable for the prevention and control of regional common comorbidities. Urban areas may be a key focus for lifestyle interventions.

Virtual screening of antithrombotic alkaloids from Houttuynia cordata / 中国中药杂志

Antithrombus is one of the effective methods to prevent and treat cardiovascular diseases. Based on the theory of traditional Chinese medicine,the author's previous research and relevant literature,it was found that the alkaloids in Houttuynia cordata has potential antithrombotic effect. However,the pharmacological substance basis and antithrombotic mechanism of H. cordata have not been clarified. In this study,molecular docking was used for virtual screening of antithrombotic alkaloids from H. cordata. Seventy alkaloids selected from H. cordata were screened in the docking ligand data-base with teen thrombosis targets with known crystal structures as the receptors. In addition,the small-molecule approved or to be approved drugs of targets from Drug Bank database were set as a positive reference with minimum score(S value) of each target's approved or to be approved drugs as threshold. The Dock module in Molecular Operating Environment(Version 2016) software was applied to screen the potential active compounds which their scores(S value) were lower than the minimum score of reference. At last the mechanism of antithrombotic effect was preliminarily revealed by compared the main active sites of the test alkaloids with original ligands and references. This study provided some useful information to development of antithrombus drugs.

Pharmacological mechanism of traditional sedative effect of alkaloids in Nelumbinis Plumula based on network pharmacology / 中国中药杂志

Nelumbinis Plumula has the traditional sedative effect,but its mechanism is unclear. In this study,the relationship between traditional sedative effect and hypnotic effect of Nelumbinis Plumula was taken as the starting point to study the hypnotic mechanism of the major medicinal components in Nelumbinis Plumula by the network pharmacology method. Targets of active Nelumbinis Plumula alkaloids were screened by Swiss Target Prediction server,TCMSP and BATMAN-TCM. Targets of hypnotic drugs approved by FDA were screened from Drug Bank,OMIM,TTD databases. The common targets were screened by GO and KEGG pathways. Cytoscape 3. 7. 1 software was used to construct the network of " active component-target-pathway-disease". The results of network analysis showed that 21 active compounds were associated with 44 targets and 28 pathways. Among them,21 compounds,35 targets and 15 pathways were predicted to be related to sedative hypnosis. Nelumbinis Plumula showed the hypnotic effect by acting on neuroactive ligand-receptor interaction pathway,regulation of actin cytoskeleton pathway,calcium signaling pathway,cholinergic synapse pathway.This study preliminarily revealed the potential active compounds and possible mechanisms of traditional sedative effect of Nelumbinis Plumula,which provided a theoretical basis for further experimental studies on medicinal materials and its mechanisms.
