Objective To analyze the clinical characteristics and changes of serum tumor markers in lung cancer patients with different smoking status in Hanzhong area. Methods A retrospective analysis was performed on 642 hospitalized lung cancer patients in Hanzhong area from March 2017 to March 2019. According to their smoking status, they were divided into observation group (smoking history, n=404) and control group (no smoking history, n=238). Age, sex, place of residence, basic information of the disease including pathological stage, pathological type, short-term efficacy, survival and serum tumor marker level were analyzed retrospectively. Results The proportion of male in observation group (67.08%) was significantly higher(57.56%) (χ2=5.855,P2=4.824 , P2=2.110 , P2=15.291, P 2=10.817,P2=2.051, P>0.05). The 1-year survival rate of the observation group (64.85%) was significantly lower than that of the control group (73.95%) (χ2=5.255, P<0.05). Conclusion Middle-aged and elderly male smokers in Hanzhong area have a high incidence of lung cancer, multiple stage Ⅲ squamous cell carcinoma, and the level of tumor markers in serum is higher than that of non-smokers. The prognosis is not good, so we should encourage patients to quit smoking, which can improve the survival rate of patients.

@#Objective To evaluate the effect of smoking and drinking status on the prognosis of patients with esophageal squamous cell carcinoma (ESCC). Methods The clinical data of 483 patients with ESCC who underwent surgical treatment in Shannxi Provincial People's Hospital from 2007 to 2016 were retrospectively analyzed. Among them, 352 patients were male and 131 were female, with a median age of 64 (37-80) years. There were 311 smokers and 172 drinkers. The relationship between preoperative drinking or smoking status and the clinicopathological characteristics of patients with ESCC was analyzed. Log-rank method and Cox risk regression were used to conduct univariate and multivariate survival analysis, respectively. Results The preoperative smoking status was related to the patient's tumor location (P=0.030). Drinking status was associated with tumor location (P=0.001), degree of differentiation (P=0.030), pathological T stage (P=0.024) and pathological N stage (P=0.029). Univariate survival analysis showed that smoking status did not affect the disease-free survival (DFS) (P=0.188) and overall survival (OS) (P=0.127) of patients with ESCC. However, patients who drank alcohol had worse PFS than non-drinking patients (29.37 months vs. 42.87 months, P=0.009). It was further proved that alcohol consumption was an independent risk factor affecting patients' recurrence and metastasis by using multivariate analysis (RR=1.28, P=0.040). Alcohol consumption also reduced the OS of patients by 21.47 months (P=0.014), however, multivariate analysis did not yield significant results. Conclusion Preoperative drinking status is related to the stage and differentiation of patients with ESCC. It is an independent risk factor affecting the recurrence and metastasis of ESCC.

Abstract Background Substance use and smoking exert devastating impact on sleep, especially hindering the ease of falling asleep, compromising the sleep maintenance, and distorting the sleep cycles. PERIOD genes are believed to play a role in individual differences in sleep timing by influencing circadian. Objective The aim of this study was to ascertain whether Per3 VNTR variant affects suspectibility of individuals to substance use disorder (SUD) and smoking status in a Turkish population. Methods A total of 549 subjects, including 212 SUD patients, 160 smoker, and 177 healthy controls, matched by ethnicity, age, and gender, were recruited in a case-control study. Genotyping of Per3 variant was performed using PCR method. Results When the SUD, smoker groups and controls were compared in terms of 5R/5R, 5R/4R, 4R/4R genotypes, no significant difference was observed. Besides, allele frequencies of Per3 VNTR were similar among the groups. Discussion Our data indicate that Per3 VNTR variant is not associated with the risk of SUD and smoking status in our population.

OBJECTIVES: The purpose of this study was to investigate the smoking status among adult workers, and current status of sugar intake. METHODS: The survey included 500 men working in Gyeonggi-do from October to November in 2016. Questionnaire items covered their age, working status, smoking status, eating habits, eating behaviors, snack consumption status, habits and behaviors related to sugar intake. All data were analyzed by SPSS program (Ver. 23) and descriptive statistics was performed; a t-test, χ² test, One-way ANOVA and Scheffe test were used for post-hoc test. RESULTS: The study results showed that eating habits and behaviors of non-smokers were better than those of smokers. The frequency of daily snack consumption was the highest in smokers compared to and non-smokers. The smokers' favorite taste after smoking was ‘Sweet’. The average score of sugar-related nutrition knowledge was higher in non-smokers compared to smokers. Non-smokers had better recognition of ‘sugar reduction’, and smokers were more likely to eat sweet foods, respectively. On the other hand, non-smokers could observe that they were trying to control themselves for health reasons. According to the results of the study, non-smokers showed better eating habits and dietary habits and consumed less sugar. Also, it was found that non-smokers tried to drink more water than beverages and refrain from eating sweets to reduce their sugar intake. Further, the most of the bread, coffee and beverages were also consumed at a lower frequency by non-smokers compared to smokers. CONCLUSIONS: This study results showed that smoking and sugar consumption were closely related. Therefore, adult workers should actively promote and learn so that they can maintain healthy and suitable dietary habits through reduction of sugar consumption.

Background and purpose:Life expectancy has continuously improved in recently years with the development of medical level. In 2012, the amount of people who were above 60 years old has reached 810 million and account for 11% of worldwide population. The worldwide population shift towards older ages will inevitably lead to more elderly patients being diagnosed with non-small cell lung cancer (NSCLC). It still remains controversial whether sublobar resection is effective in such cases. In order to solve this question, we need to understand the clinical characteristics of these tumors. Methods:From 2006 to 2012, a total of 310 patients with NSCLC who were above 65 years old underwent surgical resection in Department of Thoracic Surgery, the First Afifliated Hospital of China Medical University and the Second Department of Thoracic Surgical Oncology, Jilin Province Tumor Hospital. The clinical data were retrospectively analyzed in sex, stage, histology, smoking status, smoking amount, drinking status, surgical approaches, multimodality therapy and overall survival. Survival was analyzed by Kaplan–Meier method and log-rank test. Results:There were 256 (82.6%) elderly patients who underwent standard lobectomies and 54 (17.4%) patients who underwent sublobar resections. The overall 5-year survival rate was 52.9%. Patients with different surgical approaches (lobectomy and sublobar resection) had nearly the same 5-year survival rates (60.5%vs 60.8%, P=0.381). The prognosis were signiifcantly inlfuenced by gender (P=0.024), stage of disease (P=0.028), smoking status (P=0.034) and smoking amount (P=0.028). The multivariate Cox proportional hazards analysis revealed that the smoking status was associated with the hazard ratio of 1.660 (1.058-2.606;P=0.028). Conclusion:In elderly NSCLC patients, sublobar resection is considered to be an appropriate treatment in comparison with lobectomy, as this procedure provides an equivalent long-term survival. The survival of elderly patients with lung cancer is closely related to the smoking status.

Objective: To investigate the compliance of smoking cessation and the effect of smoking status on long-term clinical prognosis in male patients with acute coronary syndrome (ACS) after drug-eluting stent (DES) therapy. Methods: A total of 656 ACS patients after DES therapy were studied, according to the post-operative smoking status, the patients were divided into 3 groups: Non-smoking group,n=226, Quit smoking group,n=283 and Persistent smoking group, n=147. The patients were followed-up for the average of 27 months, the major adverse cardio-/cerebral-vascular events (MACCE) were recorded in detail, and the effect of smoking status for MACCE occurrence were evaluated by multivariable Cox regression analysis. Results: The pre-operative smoking rate was 65.5% (430/656) of patients and post-operative smoking rate was 22.4% (147/656). Compared with Non-smoking group and Quit smoking group, the patients in Persistent smoking group had the younger age (P<0.001), more patients with abnormal blood lipids (P=0.005) and having lower level of education (P<0.001). The all cause death rates in Non-smoking group, Quit smoking group and Persistent smoking group were at 1.8%, 1.1% and 6.1% respectively,P=0.004; the MACCE occurrence rates were at 7.1%, 5.3% and 15.0% respectively,P=0.002. Multivariable Cox regression analysis showed that post-operative smoking was the independent risk factor for MACCE occurrence, HR =1.404, 95% CI (1.206-1.793),P=0.008. Conclusion: Smoking is the independent risk factor for MACCE occurrence in male ACS patients after DES therapy.

Objectives: Only a few long-term follow-up studies with a focus on the association between lung function and mortality in the Japanese population have been undertaken. In this study, we examined the associations of lung function, smoking and the results of allergy skin tests with mortality in a longitudinal study of the Japanese population. Methods: Baseline measurements were performed on residents of Fukui, Japan in 1972, and a follow-up survey was conducted in 2002. By employing a nested case-control design, 596 cases (deaths) and 596 age and sex-matched controls (survivals) were selected. Lung function was assessed using forced vital capacity (FVC) expressed as the normal percent predicted (FVC %pred) and the ratio of forced expiratory volume in 1 second (FEV1) to FVC (FEV1/FVC). Allergy skin tests were performed with extracts of house dust, candidia and mixed fungal samples (bronchomycosis). The Brinkman index was used to assess smoking intensity. The Cox proportional hazards model was used to evaluate whether lung function was associated with mortality after adjustment for other potential confounding variables. Results: Those categorized into the first- or second-lowest quartile of FVC %pred had a higher mortality [hazard ratios (HRs) and 95% confidence intervals (CIs): 2.01 (1.26−3.19) and 1.84 (1.11−3.05)], respectively. On top of these, heavy smoking (BI≥400) was associated with a higher mortality [HR and 95%CI: 1.73 (1.18−2.53)]. There were only weak of associations between the results of allergy skin tests and mortality. Conclusions: These results suggest that FVC %pred of lung function and smoking can serve as long-term independent predictors of mortality.

BACKGROUND: Although the rate of smoking in adults is decreasing, its rate in adolescents keeps increasing gradually. Especially, smoking in adolescents is a serious problem that may be deeply related to drug abuse and is the main cause of a number of diseases. Anti-smoking program is essential to prevent this matter. Therefore, analysis of smoking status and its related factors in adolescents in a region where such a program was performed may be useful. METHODS: Questionnaire-survey was performed on 1,516 students of six high schools in a city who wished to participate in the anti-smoking program and analyzed the results concerning smoking status and the related factors on 1,380 students which consisted of 862(62.5%) males and 518(37.5%) females who completed the questionnaire. RESULTS: Smoking prevalences were 40.1% in males and 17.6% in females. Height, weight, educational level of parents and occupation of father were assessed. In the case of male students, the taller they were the more they smoked. In the case of female students, the higher their mother's educational level the more they smoked. Siblings' and close friends' smoking status had influence on smoking in both males and females. Drinking status affected smoking status in both males and females. The total mean of knowledge and attitude score was 1.39 and 1.32, respectively. There was a significant difference in men's knowledge and attitude score and in women's attitude score categorized by smoking status. The men's knowledge and attitude scores were significantly higher than women's. In the results of regression, the knowledge score had a negative coefficient and the attitude score had a positive coefficient as the dependent variable was smoking status in males, and the same results were shown in females. The attitude score, drinking status and close friends' smoking status were factors that influenced smoking in males and the knowledge score, the attitude score, drinking status, close friends' smoking and siblings' smoking in females. CONCLUSION: If we apply these results in school-based anti-smoking program, it will be an effective program for high school students.

A survey of the relationship between smoking and the academic performance of 5th-year students at Kawasaki Medical School was carried out over a 2-year period (1996 and 1997). Students were asked about their smoking habits when they visited our ward to see patients. To assess their academic performance, students were divided into two groups; students who were promoted to the 5th-year without failures (straight-promotion group) and students who had repeated the same year at least once (repeater group). Among male students, smoking rates in the straight-promotion group were 48.9 % in 1996 and 39.1% in 1997, whereas those in the repeater group were 80.6% and 65.4%. Among female students, smoking rates in the straight-promotion group were 8.7% in 1996 and 9.1% in 1997, whereas those in the repeater group were 25.0% and 37.5%. The smoking rate among male students was significantly higher in the repeater group than in the straight-promotion group, whereas there was no statistical difference between the two groups among female students. Our results suggest that smoking and poor academic performance are related. More aggressive antismoking education is needed to reduce the high smoking rate among male medical students in Japan.
