摘要： BACKGROUND Oral potential malignant disorders(OPMDs)are a precancerous condition of oral disease.Several studies have found that betel quid chewing,smoking and alcohol drinking might be the risk factors of OPMDs.But the relationships of them,especially their interaction are still inconclusive.AIM To evaluate the relationship between betel quid chewing and OPMDs and to explore the interaction of smoking and alcohol drinking on the relationship.METHODS We searched Pub Med,Web of Science,Embase and the Cochrane Library databases with items complete until January 2021 for relevant studies.The research data were extracted according to the inclusion criteria.The pooled odds ratios(ORs)and 95%confidence intervals(CIs)were used to evaluate the effect size.Subgroup analysis was performed to assess interactions between exposures and OPMDs.Relative excess risk of interaction(RERI)was used to estimate the size of interaction.RESULTS Nine articles were selected in the final meta-analysis.The results showed that betel quid chewing(pooled OR:8.70,95%CI:5.18-14.61),alcohol consumption(pooled OR:1.95,95%CI:1.5-2.55),and smoking(pooled OR:4.35,95%CI:3.06-6.2)could significantly increase the risk of OPMDs compared to individuals without these behaviors.Smoking and alcohol drinking synergistically increased the association between betel quid chewing and OPMDs(pooled OR;:14.38,95%CI:7.14-28.95;pooled OR;:11.12,95%CI:8.00-15.45,respectively).The RERI;and RERI;were 2.33 and 1.47,respectively.CONCLUSION The synergistic effects between smoking/drinking and betel quid highlights the importance of focusing on individuals with multiple exposures.Further study should be conducted to confirm these interactions.

摘要： The purpose of this scoping review is to create a single narrative that describes the impact of smoking cessation on metabolic parameters in people with diabetes.It is generally well accepted that smoking enhances the harmful effects of elevated blood glucose levels,accelerating the vascular damage seen in patients with diabetes.Smoking cessation has clear benefits in terms of reducing cardiovascular morbidity and mortality.However,there is less evidence for the impact of smoking cessation on other diabetes-related complications.Studies in people with diabetes have shown improvement as well as temporary deterioration in glycemic control after ceasing smoking.Only a few studies have described the effect of quitting smoking on insulin resistance and lipid parameters,however,their results have been inconclusive.In this situation,healthcare professionals should not assume that cessation of smoking will improve metabolic parameters in patients with diabetes.It seems they should, first of all, emphasize the prevention of weight gain that may be associatedwith quitting smoking. The lack of data regarding the metabolic effects of smoking and smokingcessation in diabetes is very disappointing and this area needs to be addressed.

摘要： Objective:To study the related factors of aspirin resistance(AR)in acute ischemic stroke.Methods:A total of 138 patients with acute ischemic stroke treated in hospital affiliated to Xuzhou medical university from August 2016 to August 2018 were the study subjects,examine his medical data from the past.They were divided into the AR group(40 cases)and the non-AR group(98 cases)according to whether AR appears.Gender,disease history,biochemical indicators and etc.were compared between the two groups.The independent risk factors of AR were investigated using univariate analysis and logistic regression analysis.Results:40 cases of AR occurred in 138 patients,with an incidence rate of 28.99%.Diabetes,platelet count(PLT),microRNA-19a(m iR-19a)expression,smoking,high-sensitivity C-reactive protein(hs-CRP),Low-density lipoprotein cholesterol(LDL-C),fibrinogen(FIB)and age difference between the AR group and non-AR group was statistically significant(P0.05).Logistic regression analysis showed that the independent risk factors for AR in acute ischemic stroke were diabetes(OR=2.773,95%CI:1.102~5.065,P=0.025),miR-19a(OR=3.021,95%CI:1.322~6.545,P=0.021),hs-CRP(OR=2.719,95%CI:1.301~5.022,P=0.028)and smoking(OR=1.983,95%CI:1.114~3.887,P=0.040).Conclusion:The incidence of AR is higher in acute ischemic stroke.Risk factors include diabetes,miR-19a expression,hs-CRP,smoking,etc.Clinical intervention measures can be taken to reduce the risk of AR and improve acute ischemic stroke prognosis.

摘要： Background: It is uncertain that whether smoking is a risk factor of colorectal advanced adenomas compared to nonadvanced adenomas, so we peformed the case-control study to explore this issue. Material and Methods: The cases were defined as patients with advanced adenomas and the controls were patients with nonadvanced adenomas. Clinical data were extracted from the hospital information system. Missing data were imputed with the multiple imputation of chained equations method, and the effect of smoking on the risk of advanced adenomas was calculated by binary logistic regression models to obtain odds ratios (ORs) and 95% confidence interval. Results: Current smoking rate in patients with advanced adenomas was significantly higher than that in patients with nonadvanced adenomas (31.6% VS 23.1%), the OR of advanced adenoma for current smoking compared with nonsmoking was 1.54 (1.09, 2.18), P = 0.013, and the weighted ORs ranged from 1.50 (1.01, 2.23) to 1.58 (1.09, 2.30), and the results of sensitivity analyses were still consistent. Conclusion: In adults with Han ethnicity in South China, current smoking is a risk factor of colorectal advanced adenomas compared to nonadvanced adenomas.

摘要： In the United States, type 2 diabetes mellitus (T2DM) disproportionately affects the African American (AA) community, which has not been systematically included in molecular studies of underlying mechanisms. As part of a gene expression study, we recruited cases with T2DM and matched, unaffected controls at an urban hospital in Washington, DC, with a majority AA population. Here we describe the profile of socio-demographic, behavioral, and health-related associations of the study population. Self-reported data were collected from cases with T2DM (N = 77) and age- and gender-matched controls (N = 80), ages 45 - 65 years. Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI). As expected, obesity, hypertension, and cardiovascular disease were more prevalent in cases than in controls. Tobacco smoking and working alongside other tobacco smokers were also associated with T2DM. After adjusting for covariates, current tobacco smoking remained statistically associated with the disease (OR per half pack of cigarettes 1.43, 95% CI 1.04 - 1.95;p-value 0.027). HbA1c levels were elevated in T2DM cases who smoked more than a pack of cigarettes daily. These associations highlight the comorbid burdens of T2DM in an AA urban community setting and identify tobacco control as an unmet need for future prevention and control efforts.

摘要： BACKGROUND In healthy people,the lowest daily blood glucose concentration is usually observed in the early morning,after overnight fasting.However,the clinical relevance and the prevalence of fasting biochemical hypoglycemia(FBH)are poorly understood in people who do not have diabetes,although the clinical implications of such hypoglycemia have been extensively studied in patients with diabetes.FBH can be influenced by many factors,including age,sex,body mass,smoking,alcohol drinking,exercise levels,medications,and eating behaviors,such as breakfast skipping and late-night eating.AIM To determine the prevalence of FBH and investigated its association with potential risk factors in a population without diabetes.METHODS Clinical parameters and lifestyle-related factors were assessed in a cross-sectional study of 695613 people aged 40-74 years who had undergone a health check-up(390282 men and 305331 women).FBH was defined as fasting plasma glucose<70 mg/dL(3.9 mmol/L)after overnight fasting,regardless of any symptoms.The absence of diabetes was defined as HbA1c<6.5%,fasting plasma glucose<126 mg/dL(7.0 mmol/L),and no pharmacotherapy for diabetes.Multivariate logistic regression analysis,with adjustment for confounding factors,was used to identify associations.RESULTS FBH was present in 1842 participants(0.26%).There were significantly more women in the FBH group(59.1%)than in the non-FBH group(43.9%).Values of most of the clinical parameters,but not age,were significantly lower in the FBH group than in the non-FBH group.Logistic regression analysis showed that a body mass index of≤20.9 kg/m2(reference:21-22.9 kg/m2)and current smoking were significantly associated with FBH,and this was not altered by adjustment for age,sex,and pharmacotherapy for hypertension or dyslipidemia.Female sex was associated with FBH.When the data were analyzed according to sex,men in their 60s or 70s appeared more likely to experience FBH compared with their 40s,whereas men in their 50s and women aged≥50 years appeared less likely to experience FBH.The relationships of FBH with other factors including alcohol drinking and pharmacotherapies for hypertension and dyslipidemia also differed between men and women.CONCLUSION FBH occurs even in non-diabetic people,albeit at a very low frequency.FBH is robustly associated with low body mass and smoking,and its relationship with lifestyle factors varies according to sex.

摘要： BACKGROUND Previous meta-analyses related smoking to death or severe infection from coronavirus disease 2019(COVID-19)in hospitalized patients,but considered only a few studies,did not adjust for demographics and comorbidities,and inadequately defined smoking.AIM To review and meta-analyse epidemiological evidence on smoking and COVID-19,considering a range of endpoints,populations and smoking definitions and the effect of adjustment.METHODS Studies were identified from publications in English up to 30 September,2020 involving at least 100 individuals,carried out in Europe,Israel,America or Australasia,not restricted to those with specific other diseases,and providing information relating smoking to various COVID-related endpoints.Meta-analyses were carried out for combinations of population and endpoint,with variation studied by smoking definition,adjustment level and other factors.RESULTS From 96 publications,74 studies were identified,37 in the United States,10 in the United Kingdom,with up to four in the other countries.Three involved over a million individuals,and 37 involved less than a thousand.Adjusted results for smoking were available in 42 studies,with adjustment not considered in 20 studies.Results were considered by endpoint.No significant effect of smoking on COVID-19 positivity was seen in the general population,but there was a reduced risk in those tested.Best-adjusted estimates for current(vs never)smoking were 0.87(95%confidence interval:0.52-1.47)in the general population and 0.52(0.43-0.64)in those tested.For those hospitalized due to COVID-19,unadjusted rates were significantly increased in current smokers(1.20,1.01-1.42)and ever smokers(1.64,1.41-1.91),but those adjusted for comorbidities showed no increase for current(0.82,0.52-1.30)or ever smokers(1.00,0.76-1.32).There was little evidence to suggest that smoking was associated with intensive care admission.For those hospitalized with COVID-19,best-adjusted estimates were 0.88(0.72-1.08)for current smokers and 1.10(0.99-1.22)for ever smokers.In those hospitalized with COVID-19,smoking was not significantly related to subsequent mechanical ventilation,with best-adjusted estimates of 1.12(0.60-2.09)for current smokers and 1.05(0.88-1.25)for ever smokers.For those hospitalized with severe COVID-19,best-adjusted estimates were 0.74(0.49-1.12)for current smokers and 1.15(0.87-1.51)for ever smokers;few estimates were adjusted for comorbidities.While smoking was associated with increased mortality in unadjusted analyses,the association disappeared after adjustment for comorbidities.For example,in those hospitalized with COVID-19,the unadjusted estimate for ever smokers of 1.59(1.37-1.83)reduced to 1.07(0.82-1.38)when adjusted for comorbidities.Studies on those with severe COVID-19 showed that smoking tended to be associated with worsening of the disease.However,no estimate was adjusted,even for demographics.Estimates did not clearly vary by location or study size,and there was too little evidence to usefully study variations by age,amount smoked or years quit.CONCLUSION The increased COVID-19 death rate in smokers seen in unadjusted analyses disappears following adjustment for demographics and comorbidities.Among those tested,smoking is associated with lower COVID-19 infection rates.

摘要： Our study investigated preservation Undulate venus (Paphia undulate) by canning via three treatments that are canned raw, canned smoked and canned cooked as a healthy product with high nutritional value. Results reported that edible meat of Paphia undulate was free from Cu, Pb and Cd as a result of washing process. There was significantly (p of canned smoked and canned cooked of Paphia undulate, and there was significantly reduction of protein content (p of canned smoked and canned cooked compared with the canned raw. Significant different (p was canned raw , the three treatments of canned shellfish Paphia undulate had significant difference (p Paphia undulate showed the lowest value of pH. All treatments of canned shellfish Paphia undulate were rich in minerals where canned raw treatment was higher in Ca, Fe, Zn, Mg, and Mn. While canned smoked had minerals content lower than canned raw. Lightness (L*) had slightly difference between all treatments of canned shellfish Paphia undulate. Reduction on lightness and redness was noticed at the same time in all treatments of canned shellfish Paphia undulate, canned raw had the highest value of lightness (L*), and redness (a*). Canned smoked had the highest value of hardness followed by canned raw then canned cook. Slightly significant difference (p red canned cooked than raw canned and canned smoked, degree of canned cooked was excellent.

摘要： Electronic cigarettes (EC) have gained popularity among smokers due to their taste, smell, appearance, and easy availability compared to traditional cigarettes, as well as the perception that they are safer than traditional cigarettes. These devices result in aerosols containing nicotine, propylene glycol, glycerin, ethylene glycol, vitamin E, and chemical flavors inhaled into the lungs. Other components found in these vapors include heavy metals such as nickel, chromium, lead, manganese, and tin. In addition, some ingredients volatilization leads to toxic aldehydes formation such as formaldehyde, acetaldehyde, and acrolein. Smoking cigarettes is addictive and has been associated with many health issues such as heart disease, lung cancer, etc. Rising awareness of these dangers moves more people towards these electronic delivery systems, reducing the health effects of cigarettes. The toxicity of EC’s ingredients is well studied when ingested;however, their toxicity through inhalation remains unclear. Consequently, the use of ECs has become a significant concern worldwide and raises whether it is indeed safe to use. This paper will serve as a literature review paper to discuss the toxicity of commonly found ingredients in ECs and their associated health issues. Our conclusion emphasizes that even though smoking EC is less risker than smoking traditional cigarettes, it is still not safe due to the potentially harmful effect these E-cig’s ingredients have on the human’s health. In addition, E-cigarette’s aerosol could also contain toxic compounds such as formaldehyde, acetaldehyde, and acrolein due to glycerin’s thermo-degradation.

摘要： Background: Inverted Papilloma (IP) is the most common benign neoplasms arising from the mucosal lining of the of the Sino-Nasal tract with single or multifocal attachment sites. The high propensity to recur, local aggressive behavior and possibility of malignant transformation attract considerable interest. Objective: To assess the factors affecting Sino-nasal IP, malignant transformation rate, and post-operative recurrence rate. Methods: A retrospective study was carried out on all cases diagnosed as Sino-Nasal Papilloma between January 2010 and December 2020 at Salmaniya Medical Complex, Bahrain. Data gathered from medical records were analyzed using SPSS. A total of 49 Sino-Nasal Papilloma cases were recorded of which 37 were IP. Factors affecting Sino-Nasal IPs are presented. Results: Sino-Nasal IP was recorded in 37 cases, composed of 28 males and 9 females with first presentation average age of 45.86 years. These involved 20 cases in the left side, 14 in the right side and 3 were bilateral. Recurrence in males and females was found to be 35.7% and 33%, respectively, with an average of 12.6 months. The symptoms include nasal blockage (97.3%), epistaxis and postnasal drip (13.5% each), headache (8.1%) and hyposmia and rhinorrhea (5.4%, each). The main recurrence was at stage T2 (60.5%), while in smokers (26.7%) and non-smokers (50%). Malignant transformation occurred in one patient only (2.6%). Conclusion: IP is the most common type of SNP with male predominance. The recurrence rate is high with an average of a year and the malignant transformation occurred in 2.6 % of the cases.

摘要： Objective To investigate the exactly relationship between smoking and systolic blood pressure (SBP), diastolic blond pressure (DBP), and the rank of blood pressure, and to provide evidences for hypertension prevention and cure and tobacco control.Methods 1'he methods of mufti-stage random cluster sampling and KISH card were used to sample the investigation areas and subjects.14 investigation areas and 4480 subjects were included in this study.The questionnaire was used to investigate sex, age, smoking, drinking liquor, eating habit, physical activity, and so on, and 4318 completed questionnaires were got.Body height, bodyweight, waistline, blood pressure and other biomarkers were measured for all subjects.Results The average SBP and DBP in men were significant higher than that in women, and Heat，also in smoking and nonsmoking.The results of correlation analysis indicated that there were significant relationships between the amount of tobacco use and SBP (pearson correlation-0.067, p=0.004), DBP (pearson correlation=0.075, p=0.001)，and rank of blood pressure (pearson correlation=0.053, p=0.022).As the age, sex, BMI, waistline, and so on were adjusted, the results of multi-Logistic analysis indicated that OR of got hypertension was 1.196 (95% CI was 1.056-1.355) in smoking person compared with nonsmoking, the OR was increased as the, amount of tobacco use was raised.Conclusion There were significant relationships between smoking and SPB, DBP and the rank of blood pressure.Smoking can significant increase the risk of hypertension.
