ABSTRACT
Objective@#To explore the roles of self efficacy and smoking rationalization tendency in the relationship between college students physical activity and smoking cessation beliefs, in order to provide a basis for the positive effects of college students physical activity on smoking cessation beliefs.@*Methods@#From May 6 to 23 in 2023, 3 048 students from 10 colleges in Jiangxi Province were recruited and surveyed using the Physical Activity Participation Scale, the Smoking Cessation Self efficacy Scale, the Smoking Rationalization Tendency Scale and the Smoking Cessation Belief Scale. The Harman one way test was adopted for common method bias test. Bias correction was unfolded by Bootstrap method, and 95% confidence intervals of parameter estimates were analyzed using repeated sampling 5 000 times.@*Results@#The results of the sequential mediation model analysis showed that physical activity was positively associated with college students beliefs about smoking cessation ( β =0.17), and physical activity, self efficacy and smoking rationalization tendency were positively associated with each other ( β =0.41, 0.08, 0.19) ( P <0.05). Both self efficacy and smoking rationalization tendency positively predicted smoking cessation beliefs ( β =0.19, 0.17, P <0.01). Self efficacy and smoking rationalization tendency mediated the relationship between physical activity and smoking cessation beliefs, with a mediating effect value of 0.09, accounting for 62.82% of the total effect value (0.15).@*Conclusions@#Self efficacy and smoking rationalization tendency have a serial mediating effect between physical activity and smoking cessation beliefs among college students. Interventions should be actively used to enhance college students beliefs about smoking cessation, promote smoking cessation behaviors.
ABSTRACT
Objective To investigate the effects of inhibiting vesicular glutamate transporters (VGLUT) on pain behaviors in animals. Methods The latency in hot plate test, number of writhes in acetic acid and licking time in formeldehyde solution (formalin) tests were recorded to determine the analgesic effect of Chicago sky blue 6B (CSB6B), a selective VGLUT inhibitor. Results Intraperitoneal administration of CSB6B did not affect the acute thermal pain responses in hot plate test. In acetic acid writhing, compared with control group (26.50 ±2.97), CSB6B (2.5 mg/kg, ip) significantly attenuated the acetic acid-induced writhing (8.22±1.90) 30 min after administration (P<0.01);CSB6B (2.5 mg/kg, ip) significantly reduced the acetic acid-induced writhing(9.60±1.84) 60 min after administration(P<0.01). In Formalin test, compared with control group(139.40±21.02), CSB6B (0.5 mg/kg, ip) significantly reduced the licking time(75.10±19.45) 30 min after administration(P<0.05) during the second phase, but not during the first phases. CSB6B(ip) did not affect the licking time 2 h after administration during the first and second phases. Conclusion Inhibition of VGLUTs activity is sufficient to attenuate the inflammatory pain and this finding suggests that VGLUT participate in regulation of inflammatory pain and be a novel therapeutic strategy for treatment of pain.
