ABSTRACT
Objective To investigate the effectiveness of Varenicline combined with MEDCHART application software for health education and follow-up in patients at smoking cessation clinic.Methods A total of 104 cases who had smoking cessation counseling and intervention at smoking cessation clinic from February 2014 to January 2015 were divided randomly into MEDCHART APP group (n=51) and conventional group (n=53).Both groups were intervened by brief admonishment and given Varenicline.The 9-12 weeks and 26th week protracted continuous abstinence rates were observed.Results There were no significant difference in 9-12 week protracted withdrawal rate between 26th week APP and conventional groups (56.9％ vs.45.3％),the 26th week abstinence rates in group MEDCHART APP (41.2％) were significantly higher than the conventional group (20.8％)(x2=5.088,P＜0.05).There was significant difference in full course completion rates between the two groups;15 cases (29.4％) completed the course in group MEDCHART APP,whereas 5 cases (9.4％) did so in conventional group (x2=4.405,P＜0.05).Conclusion MEDCHART APP can strengthen health education and follow-up,which helps extend the time for Varenicline,increase 26th week smoking cessation withdrawal rate.It is a useful tool for smoking cessation education and follow-up.
ABSTRACT
With the foreign students into the clinical practice stage,how to improve the teaching quality is very important for teachers. Sufficient preparations before practice; adopting PIO teaching methods; training the exact thinking of the clinical medicine and examing students'medical case records in detail are important factors to the successful teaching.
ABSTRACT
AIM:To investigate rat Urotensin-II(ra t U-II)-induced vasoconstriction of rat main pulmonary arteries and the role of mitogen-activated protein kinase(MAPK). METHODS: The main pulmon ary artery was dissected from the male Sprague -Dawley rats and artery ring width was 3-4 mm. Concentration-response curves wer e gene rated to rat U-II(0 03 nmol/L-30 nmol/L).Inhibitor of MAPK,PD 98059(0 1 ?mol/ L -10 ?mol/L) were added into the medium after rat U-II(30 nmol/L)induced vasoc onstriction had reached plateau to construct the relaxant concentration-respons e curves and their EC 50 and E max . RESULTS: Rat U-II was a potent vasoconstrictor of isolated rat main pulmonary arteries [EC 50 =7 95?0 4 0, E max =(14 28?6 34)% of the response to 60 mmol/L KCl]; PD 98059 caused c oncentration-dependent relaxations of rat U-II precontracted arteries [EC 50 =5 91?0 45, E max =(81 39?13 65)%]. CONCLUSION: Rat U- II was a potent vasoconstrictor of rat main pulmonary arteries and this response was med iated through MAPK.
