ABSTRACT
Objective:To evaluate the effect of stratified management of cardiovascular diseases risk in community population based on China-PAR.Methods:It was a single arm study. Beijing Jiaotong University faculty and staff who participated in annual health check-up from 2019 to 2021 and met the inclusion/exclusion criteria were enrolled in the study. The general data, physical examination and laboratory test results, including age, residence region, waist circumference, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C),blood pressure (BP), taking antihypertensive drugs,diabetes, family history of cardiovascular diseases,were collected. Participants were stratified according to China-PAR assessment model and then stratified management was carried out. For low-risk populations, family doctors provided online guidance or outpatient follow-up if necessary after their first interview. For middle and high-risk groups, outpatient and telephone follow-up were arranged in addition to online guidance. Relevant examinations were completed and drug treatment or adjustment were given by doctors when necessary. Frequency of outpatient follow-up for middle and high-risk groups was different and patients in these two groups were scored again at the end of 2-year follow-up.Results:A total 284 participants were enrolled,197 participants (69.4%) were males with a age of (46.9±8.8) years. Among them, 205 participants (72.2%) were in low-risk group, including 136 males (66.3%), and their 10-year risk of cardiovascular diseases was (2.5±0.1)%; 59 participants (20.8%) were in middle-risk group, including 43 males (72.9%), and their 10-year risk of cardiovascular diseases was (7.1±0.2)%;20 participants (7.0%) were in high-risk group,including 18 males (90.0%) and their 10-year risk of cardiovascular diseases was (14.0±1.1)%. After 2 years follow-up, the proportion of dietary imbalances and alcohol drinking, waist circumference, blood pressure, fasting glucose levels and risk score decreased significantly in high risk group ( P<0.05). The proportion of dietary imbalances, waist circumference, blood pressure, total cholesterol, and LDL-C levels decreased significantly in medium risk group ( P<0.05). In high-risk group, 2 participants (10.0%) converted to low-risk, 8 participants (40.0%) converted to middle-risk. In middle-risk group, 5 participants (8.5%) converted to low-risk and 7 participants (11.9%) converted to high-risk. Conclusion:The risk factors and risk stratification of cardiovascular disease in community population can be improved by stratified management based on China-PAR risk assessment model.
ABSTRACT
Objective To explore the relationship between cellular rejection and the development of allo-or xenografted primordia from different gestational ages .Methods Whole rat metanephroi from embryonic day E14～ E19 were transplanted into omenta of outbred (SD → SD ,6 groups ,n≥10 each ;E15-E17SDCsA ,3 groups ,n=15 each) ,syngeneic (Lewis→Lewis ,5 groups ,n=8 each) ,allogeneic (Lewis→BN ,E15BN n= 6 each E15BNCsA n= 10 each ,E16BNCsA n= 10 each) rats and xenogeneic (Lewis→C57groups ,E15C57 n=10 each ,E15C57CsA ,n=8 each ;Lewis→Balb/c nude mice ,3 groups ,n=10 each) recipients .Histopathology ,Banff's grading and electron microscopy (EM ) were utilized for assessing the graft development .Similarly ,biochemical indicators and creatinine clearances were measured .Results At 4 weeks post-transplantation , in SD → SD groups ,E14-E17SD metanephroi developed with Banff ' s rejections . E14/E15SD was significantly lighter than E16/E17SD ( P< 0 .01 );E18/E19SD barely developed . After cyclosporine A (CsA , 8 mg·kg -1·d-1 )dosing ,Banff's rejection of E15-E17SDCsA group lessened significantly .In Lewis→BN ,E15BN metanephroi were completely rejected .After dosing CsA (12 mg·kg -1·d-1 ) ,E15BNCsA and E16BNCsA Banff ' s rejections became alleviated . Upon a discontinuation of CsA , both metanephroi were rejected . In Lewis → Lewis , E15 ～ E17Lewis metanephroi developed well . No significant difference existed in Banff's classification (P>0 .05) .E14Lewis and E18Lewis rats had significantly poorly differentiated metanephroi than those in E16 Lewis group .In Lewis→C57BL/6 , E15 metanephroi were rejected at Day 14 post-transplantation (n= 10) and no improvement was evident after CsA dosing (15 mg·kg -1·d-1 ,n=8) .In Lewis→Balb/c nude mice ,all E15～E17Balb/c metanephroi developed well .Both light microscopy and EM examination showed normal nephrons and collecting ducts and wet weight ,creatinine or urea nitrogen of effusion showed no significant difference (P>0 .05) .E15Lewis and E16Lewis had significantly different values of wet weight and creatinine clearances from those of E15SDCsA and E16SDCsA .E15SDCsA had the greatest wet weight and the lowest creatinine clearance rate (P< 0 .01) .Conclusions After controlling rejection during allo-and xenotransplantations ,E15 ,E16 and E17 rat metanephros have similar development characteristics . And cellular immunogenic factors still remain the major barriers to their developments .
ABSTRACT
Objective:To compare acquired immune deficiency syndrome (AIDS) related knowledge, attitudes, behaviors and their influencing factors among college students in different years in Beijing, and to provide evidence for targeted health education among college students in future.Methods: College students were selected by the stratified cluster sampling method, and a questionnaire survey was conducted among college students in year 2006 and 2016 in Beijing.The sample sizes were 1 800 and 3 001 college students, respectively.The contents of the questionnaire included: socio-demographic characteristics, AIDS related knowledge, AIDS related attitude, sex intercourse and its related risk behaviors, condom use intension, and AIDS related health education.Results: Compared with the year 2006, the average AIDS knowledge scores of college students in year 2016 dropped from 12.78±1.95 to 11.90±2.56 (t=12.91, P<0.05), and the correct answer rates of questions in the knowledge part were decreased, too.Except for belief on condom use, the college students were more negative on AIDS related attitude and self-efficacy in year 2016 than in year 2006.Among the students who had sex experience, the rates of commercial sex [17.65% (33/187) vs.6.53% (16/245), χ2=13.003, P<0.001] and the rates of homo-sexual intercourse [15.43% (29/188) vs.4.13% (10/242), χ2=16.356, P<0.001] were higher in year 2016 than in year 2006.The main way for the students seeking pornographic information was changed from books to internet (41.15%) in 2016 compared with the year 2016.In 2016, the influencing factors of intention on condom use were male (OR=0.713), self-efficacy of condom purchase (OR=0.876), never received sex education before college (OR=0.752), self-efficacy of condom use (OR=1.135), belief of condom use (OR=1.775), and attitude towards AIDS patients (OR=1.136).Conclusion: AIDS related knowledge, attitudes and behaviors among college students have been changed, AIDS related health education should be designed and improved based on new characteristics of college students.AIDS health education in colleges should pay more attention to sex attitude and sex responsibility and self-protection awareness among college students as well.
ABSTRACT
<p><b>OBJECTIVE</b>To understand status of health literacy among diabetics and their health management behaviors, and analyze the relationship of health literacy and health management.</p><p><b>METHODS</b>A two-staged cluster randomized sampling method was used to investigate 1 130 diabetics in Beijing, Ningbo and Xiamen from October to November in 2012. All participants should be diagnosed by primary hospital and above and have lived in the community over six months. Diabetic patients who indicated that they had severely impaired vision or cognitive disorder, or had severe physical deterioration, or did not live in the address provided were excluded. A total of 1 130 questionnaires were sent out and 1 083 eligible questionnaires were taken back, accounting for 96.87%. Multivariate logistic regression was adopted to analyze the association between health literacy and health management behaviors and blood glucose level.</p><p><b>RESULTS</b>Among those participants, 47.7% (517) were men, 52.3% (566) were women, the age was (67.0 ± 9.5). According to diabetes health literacy scores, 73.7% (798/1 083) of them were classified as poor health literacy and 26.1% (283/1 083) as essential health literacy. Health literacy was associated with health management behaviors independently, demonstrating that the probability of utilizing health education, free physical examination, lifestyle guidance, monitoring blood glucose on their own, measuring blood glucose more than once a week and taking hypoglycemic agent regularly among diabetics with essential health literacy were 1.40 (95%CI:1.03-1.91), 1.65 (95%CI: 1.19-2.28), 2.70 (95%CI:1.98-3.69), 2.05 (95%CI:1.34-3.15), 2.56 (95%CI:1.85-3.56) , 1.48 (95%CI:1.07-2.06) times of those in diabetics with poor health literacy (P < 0.05).</p><p><b>CONCLUSION</b>Health literacy may affect health management behaviors among diabetics. More activities targeted on diabetics with low health literacy were suggested to improve their' health literacy and their skills about diabetes mellitus management.</p>
