Impact of intervention on tobacco related knowledge, attitudes and practice of smokers / 中华流行病学杂志

<p><b>OBJECTIVE</b>To evaluate the impact of intervention on tobacco related knowledge, attitudes and practice of smokers.</p><p><b>METHODS</b>An observational study was conducted among the smokers seeking counsel at smoking cessation clinic in our hospital from October 2008 to August 2013. First, a face to face counsel and mental intervention for more than 30 minutes was given to smoker, then 4 interventions through telephone call for 15-20 minutes for each time were conducted 1 week later, 1 month later, 3 months later and 6 months later, respectively. The controls were smokers receiving health examination in our hospital. No interventions were conducted among them. The tobacco related knowledge, attitudes and practice at baseline survey and follow up 1 year later were compared between intervention group and control group.</p><p><b>RESULTS</b>The intervention group included 414 smokers and the control group included 213 smokers. Intentional analysis indicated that the awareness/acceptance rates of 5 items about tobacco related knowledge and attitudes at follow up 1 year later was higher than those at baseline survey in intervention group. The smoking cessation rate was 27.3% in intervention group and 4.7% in control group. Multivariate logistic regression analysis indicated that the smoking cessation rate was positively correlated with intervention, female, highly nicotine dependence and positive change of tobacco related knowledge and attitudes (smoking can cause heart disease, all kinds of tobacco advertisements should be prohibited, smoking waste money and restaurant should be smoking free) with OR (95% CI): 2.85 (2.00-4.07), 3.34 (1.23-9.07), 2.78 (1.64-4.72), 2.30 (1.03-5.15), 5.33 (1.47-19.32), 6.32 (1.56-25.62) and 10.47 (2.25-48.84), respectively.</p><p><b>CONCLUSION</b>The awareness rate of tobacco related harm was high among the smokers seeking counsel at smoking cessation clinic. Systematic smoking cessation intervention can improve smokers' tobacco related knowledge and attitudes and increase smoking cessation rate.</p>

Effectiveness of Varenicline with counseling programs on smoking cessation in a targeted clinical setting in China / 中华流行病学杂志

<p><b>OBJECTIVE</b>To evaluate the effectiveness of Varenicline for smoking cessation in a community-based smoking-cessation-clinic (SCC) in Chinese smokers.</p><p><b>METHODS</b>A prospective observational study was conducted in Beijing, China. 799 smokers (762 men and 37 women) were assessed on data gathered from structured questionnaires at baseline and follow up programs at 1, 3 and 6 months. Trained physician counselors provided free individual counseling and follow-up interviews with brief counseling for all the subjects. 272 subjects were additionally prescribed Varenicline according to their own choice and reported data were compared to those without Varenicline. Outcomes were self-reported, regarding the 7-day point prevalence on abstinence rate and continuous abstinence rates at 1, 3 and 6 month follow-up periods.</p><p><b>RESULTS</b>At 6-month and by intention-to-treat, the 7-day point prevalence on abstinence rate with Varenicline and counseling, was significantly higher than the group with counseling only (34.6% versus 23.1%; OR = 1.75, 95% CI: 1.27-2.42;P < 0.001). The 3-month continuous abstinence rate at 6 month was higher in the group with Varenicline(31.3% versus 18.2% ;OR = 2.04, 95% CI:1.46-2.86;P < 0.001). Varenicline also showed better outcomes at 1 and 3 month follow-up.</p><p><b>CONCLUSION</b>Varenicline prescription in the smoking cessation clinic appeared to be effective that doubled the rates of quitting among Chinese smokers in the practice at a community-based SCC.</p>

Predictors for 'successful quitting smoking' among males carried out in a smoking cessation clinic / 中华流行病学杂志

<p><b>OBJECTIVE</b>To investigate the predictors for 'quitting' among male smokers in a smoking cessation clinic.</p><p><b>METHODS</b>The target population consisted of smokers who volunteered to seek treatment for cessation at our clinic in Beijing. Smokers received face-to-face counseling and psychological intervention at the first visit by trained physicians and standardized telephone discussion, was carried out with counselors at 1 week, 1/3/6 months a follow-up study. The main outcomes would involve 'successful quitting' at the 7-day point, continuous quit rates at 3 and 6 months as well as the predictors of 'quitting'.</p><p><b>RESULTS</b>From October 2008 to December 2012, we collected 355 eligible male smokers among whom 255 had completed the 6-month follow-up program. Results from the analysis (n = 255) showed that the quitting rates at the 7-day point and 3 months were 34.9% and 25.5%, while the rates were 25.1% and 18.3% among the 355 smokers who had the intention for treatment. Data from the stepwise logistic regression model analysis showed that lower exhaled CO level at the first visit, higher perceived confidence in quitting, lower expenditure on cigarettes and had diagnosed tobacco-related chronic diseases by physicians, were important predictors for quitting smoking. The main reasons of failure to quit were addiction of tobacco cigarette, craving for cigarettes to relieve pressure from work, peer influence from other smokers, lack of mental preparation and perseverance to quit, etc.</p><p><b>CONCLUSION</b>Smokers who smoked less cigarettes, had higher perceived confidence in quitting and had physician-diagnosed tobacco-related chronic diseases seemed easier to quit. Regular follow-up intervention services for smokers should be established to enhance the motivation for quitting so as to create a favorable environment for the smokers.</p>

Correlation between flagellin and TNF-? in acute lung injuries induced by sepsis in rats / 解放军医学杂志

Objective The aim of present study was to observe the correlation between flagellin and tumor necrosis factor ?(TNF-?)in rats with sepsis-induced acute lung injury(ALI).Methods A total of 120 male healthy Wistar rats were randomly assigned into 2 groups:sepsis group which was reproduced by cecal ligation and puncture(CLP),and sham operated group which underwent laparotomy only.All the indexes were observed at the time points of 2h,4h,6h,12h,24h and 48h after operation.Changes in partial pressure of oxygen in artery(PaO2)were determined by blood gas analysis.Pathological changes in pulmonary-tissue were observed by light microscopy.The levels of flagellin in serum,bronchoalveolar lavage fluid and pneumono-homogenate,as well as TNF-? of serum,were determined by enzyme linked immunosorbent assay(ELISA).Results Rats with acute lung injury induced by sepsis was successfully reproduced.The PaO2 of sepsis group significantly decreased at 12h after injury and reached the lowest point at 48h after injury.PaO2 of sepsis group was remarkably lower than that of sham operated group at the time points of 12h,24h and 48h after injury(P
