ABSTRACT
Objective@#To explore the relationship among jogging risk perception, jogging risk behavior and the incidence of jogging risk, so as to provide a feasible way to reduce the risk of college students extracurricular jogging exercise.@*Methods@#The method of convenience sampling was used to conduct a follow up survey among 470 college students at a university in Beijing participating in extracurricular jogging exercise and the sports world campus app was used to record and monitor jogging exercise. During the tracking period, the jogging related information was counted once a month, a total of 6 times. At the same time, three questionnaires were distributed in three stages to collect relevant information. SPSS 26.0 was used for the descriptive analysis, and AMOS 22.0 was used for correlational analysis.@*Results@#The risk rate of extracurricular jogging exercise of college students during the past academic year was 71.06 %, score of knowledge on jogging risk was(3.68±0.59), was (3.25±0.91)for jogging injury, and was( 3.23± 0.96)for jogging related disease. Significant negative correlation between college students jogging risk perception and jogging risk behavior ( r =-0.34), negative correlation between jogging risk perception and the incidence of jogging injuries ( r =-0.27), and positive correlation between jogging risk behavior and the incidence of jogging injuries ( r =0.28) were observed( P <0.01). PE(physical education) class was the main way of obtaining the knowledge about jogging risks among college students(43.40%). @*Conclusion@#College students show high vulnerability for extracurricular jogging related risks, and low level of perception of jogging risks and jogging injuries. Relevant measures need to be taken to improve the cognitive level of running risk among college students, so as to reduce the incidence of running risk.
ABSTRACT
Objective:To study the difference in dissolution behavior of clozapine tablets in four different media between the do-mestic preparations and original preparation to compare the internal quality of the tablets from various manufacturers and provide refer-ence for the drug control. Methods:Referring to the methods of in vitro dissolution test, the dissolution profiles of 46 batches of sam-ples from 18 pharmaceutical enterprises were determined in four kinds of dissolution media with different pH values, and the results were compared with that of the original drug by the method of f2 similarity factor. Results: Totally 46 dissolution profiles were drawn out. The profiles of two batches of samples from one pharmaceutical enterprise were similar to that of the original drug, which account-ing for 4%, and that of the other samples showed notable difference from that of the original drug. Conclusion:The preparation tech-nology of the tablets from domestic has great difference, which leads to significant difference in dissolution behavior. The screening and optimization of the production process in domestic pharmaceutical enterprises should be strengthened to improve the preparation technol-ogy of clozapine tablets.
