ABSTRACT
Objective@#To study the current situation and influencing factors of college students use of fitness live stream, so as to provide a reference basis for promoting the scientific fitness of the whole people, especially the physical health of young college students.@*Methods@#A total of 2 151 sample students of 18 colleges from Zhengzhou, Kaifeng and Luoyang in He nan Province, were by the three stage random sampling method from May to August in 2022. Univariate analysis and Logistic regression model were constructed to study the influencing factors of the use of fitness live stream among college students.@*Results@#About 48.6% of college students reported of using fitness live stream, which varied significantly by genders, grades, major, monthly consumption, health attitudes, fitness awareness, fitness motivation, and fitness frequency ( χ 2=111.17, 39.06, 218.45, 278.05, 515.67, 30.45 , 104.17, P <0.01). The results of Logistic regression analysis showed that gender, grade, major, monthly consumption, health attitude, fitness awareness, fitness motivation and fitness frequency were the main factors related to the use of fitness live stream among college students ( OR =1.12-2.25, P <0.01).@*Conclusion@#The college student community has a high acceptance of fitness live stream. Appropricate fitness awareness and fitness behaviors could also promote college students to actively participate in the activities of fitness live stream.
ABSTRACT
Objective@#To analyze the current situation and associated factors of fitness APP usage among college students.@*Methods@#By using three stage compound sampling method, 2 171 college students were selected, and a binary Logistic regression model was established to analyze the influencing factors fitness APP usage.@*Results@#The rate of fitness APP usage among college students was 61.9%, with significant differences by grade, physical health perception, fitness awareness, fitness purpose and exercise frequency( χ 2=28.01, 37.15, 214.12, 32.23, 316.21, P <0.01). The Logistic regression analysis showed that, grade( β = -0.31 ), fitness awareness( β =0.46), fitness purpose (improving health, β =0.52, weight loss, β =0.65), APP user friendliness ( β =0.34) and specific type of sports (running, β =1.24, racket movement, β =0.80) were associated with fitness APP usage( P < 0.05 ). Gender( β =0.30), major ( β =0.01) and exercise frequency ( β =-0.29) have less effect on fitness APP usage among college students( P >0.05).@*Conclusion@#College students have a high level of acceptance and usage of fitness APP. Grade, fitness awareness and purpose, sports type and fitness APP design are prominent factors affecting fitness APP usage among college students. The personalized custom design of fitness APP could be improved for college students.
ABSTRACT
Objective To report our first clinical experience with a novel modified culotte technique for the treatment of true coronary bifurcation lesions. Methods The novel modified culotte technique (the mono-ring culotte) stenting was done in which the side branch (SB) stent was deployed firstly followed by ex vivo wiring of a most proximal cell of SB stent with the hard end of main branch (MB) wire. Secondly, the MB stent was deployed through the most proximal cell of SB stent. The procedure was ended with kissing balloon dilation. From June 2014 to March 2015, 15 patients with true coronary bifurcation lesion were treated with mono-ring culotte stenting in our center. Results The procedures were successful in all cases without procedural complication and in-hospital major adverse cardiovascular events. The procedural time was (34. 3 ± 9. 6) min, fluoroscopic time was (18. 1 ± 3. 8) min, and contrast volume was (112. 0 ± 24. 5) ml, respectively. Post-procedurally, the residual stenosis of the main and the side branch were (10. 0 ± 2. 5)% and (10. 2 ± 5. 3)% , respectively. Conclusions The mono-ring culotte stenting is safe and feasible for treatment of true coronary bifurcation lesions, and may be superior to the conventional culotte stenting.
ABSTRACT
Objective To evaluate the changes of cardiac function, cardiac cavity size and hemodynamic after percutaneous balloon mitral valvuloplasty (PBMV) in patients with rheumatic mitral stenosis and small left ventricle Methods PBMV was performed with Inoue technique in 27 patients with rheumatic mitral stenosis and small left ventricle The diameter of balloon was the height (cm) of patient/10+10 mm To measure the changes of hemodynamic during PBMV; to evaluate the cardiac function, size of the left atrium and ventricle, mitral valve area and its mean gradient, maximal pulmonary systolic pressure by echocardiogram 1 week before PBMV and 1 week, 1, 3, 6 month after PBMV Results The left atrial pressure, mean gradient and diastolic murmur decreased; and diastolic pressure of left ventricle increased immediately after PBMV; the cardiac function improved at 1 month after PBMV Conclusion The diameter of balloon can be height (cm) of patient/10+10 mm in the patients with rheumatic mitral stenosis and small left ventricle The cardiac cavity size has significant changes at 1 week and the largest effect was seen at 1 month At 1 month the cardiac function has been improved apparently
ABSTRACT
Objective To compare the procedural difficulty index (PDI) and immediate outcome (IM) of percutaneous coronary intervention (PCI) in patients with various stages of myocardial infarction.Methods Ninety-four patients with myocardial infarction were divided into three groups, direct PCI(n=38), delayed PCI(n=22) and late PCI(n=34). The characteristics of infarct-related coronary artery, PDI and IM of PCI were evaluated angiographically, and severe procedural complications (SPC) and major adverse cardiac events (MACE) during hospitalstay were documented. Results In the three groups, PDI was 1.47 ?1.79, 1.82 ?1.72 and 2.85 ?2.83, respectively (P
