报道了利用同步辐射真空紫外单光子电离飞行时间质谱技术实时分析卷烟烟气的新方法，及其对两种不同类型卷烟主流烟气气相成分进行分析研究所取得的一些实验结果。首先，采用自行设计的注射器对卷烟烟气进行采样，初步研究了陈化时间对烟气化学成分的影响，并通过扫描光电离效率谱（PIE）曲线获得了一些不同质量数的烟气组分的电离能；然后，利用改造后的单通道吸烟机在国际标准条件下抽吸卷烟，探讨了某些单口烟气成分随抽吸口数的变化情况。结果表明，虽然陈化时间对卷烟烟气气相成分有较为明显的影响，但是通过PIE的测量能够较好地对烟气组分进行定性分析；另外，采用商用吸烟机与同步辐射光电离质谱相结合能够实现无需对样品进行前处理的条件下，在秒量级时间内对单口烟气进行分析。

A new method using synchrotron radiation vacuum ultraviolet (VUV) single-photon ionization time-of-flight mass spectrometry for real-time analysis of cigarette smoke was developed by utilizing a home-made sampling device for collecting mainstream smoke and a modified Borgwaldt single-port smoking machine. Results showed that qualitative analysis of multiple components of tobacco smoke can be well accomplished by scanning photoionization efficiency spectra (PIE), although there were aging effects. In addition, commercial smoking machine combined with synchrotron radiation VUV photoionization mass spectrometry can realize puff-by-puff analysis of cigarette smoke without pre-treatment within a few seconds.

应用气相色谱法/原子发射检测器（ GC/AED）分离检测主流烟气粒相物中的含氮碱性成分。3种类型烟叶（典型烤烟、白肋烟和香料烟）、不同香型烤烟烟叶和成品卷烟经过吸烟机抽吸后，收集主流烟气粒相物。粒相物经过连续萃取和反萃取分离，得到含氮的碱性成分，进行GC/AED检测。结果表明，GC/AED能够检测出主流烟气中吡嗪类、吡啶类和烟草微量生物碱类成分。比较了不同样品含氮成分的异同，结果表明，白肋烟烟叶主流烟气粒相物中含氮成分较多，含量最高，烤烟和香料烟烟叶主流烟气粒相物中含氮成分相对较少，含量较低；不同香型烤烟烟叶主流烟气粒相物中主要含氮成分基本类似；不同品牌卷烟主流烟气粒相物中主要含氮成分基本类似，烤烟型卷烟假木贼碱相对百分含量较高（3.84％～4.62％），而混合型卷烟降烟碱相对百分含量较高（5.22％）。

Compounds containing N element in particulate matter of mainstream smoke of different tobacco samples were isolated and determined by GC/AED.The particulate matters of mainstream smoke from 3 types of tobacco leaves ( typical flue-cured tobacco leaf , burley tobacco leaf and orien-tal tobacco leaf ) , different flavor flue-cured tobacco leaves and cigarettes with different brands were collected through smoking machine .The particulate matter was successively extracted with different solvents.Then alkaline extractants containing N element were collected and determined by GC /AED.The results showed that the derivatives of pyrazine , pyridine and tobacco trace alkaloids could be detected by GC/AED.The compounds containing N element in different samples were compared .The kinds and amount of compounds containing N element in the particulate matter of mainstream smoke of burley tobacco leaf were more than those in flue-cured tobacco and oriental tobacco leaves . The kinds and amount of comp

It also will expound the innovation and advance of M8’s rod formation technology by comparing the theory with the production. It is the rod formation technology that guaranties the quality of cigarette while the cigarette maker has an extreme high production speed – 20000 cigarettes per minute.

探讨患者吸烟情况与冠脉旁路移植术(CABG)术后早期结果的相关性。方法:对我院2010年1月至2012年12月间接受CABG的患者共489例行回顾性分析,根据患者术前是否吸烟分为吸烟组(n=276),不吸烟组(n=213)。根据术前戒烟情况将吸烟组分为戒烟亚组(n=81),未戒烟亚组(n=195)。结果:(1)吸烟组患者体质指数、高血压、高脂血症、心肌梗死病史、合并COPD史显著高于不吸烟组,吸烟组平均年龄、左心室射血分数显著低于对照组(均P0.05),戒烟亚组与未戒烟亚组上述指标比较无统计学差异(P0.05)。(2)去除COPD患者分析发现,不吸烟组患者术后肺部并发症、呼吸机辅助时间显著低于吸烟组,戒烟亚组患者术后肺部并发症、呼吸机辅助时间显著低于未戒烟亚组(均P0.05)。(3)Logistic多因素分析显示患者住院期间肺部并发症与患者吸烟情况相关(P0.05)。结论:吸烟可以影响CABG患者早期预后,患者术后肺部并发症增加,呼吸机辅助时间延长,应鼓励CABG患者术前及早戒烟,降低术后并发症。

Objective To investigate the correlation analysis of smoking on early outcomes in patients with coronary artery bypass graft surgery. Methods 489 patients undergoing CABG in our hospital from January 2010 to December 2012 were analyzed retrospectively. Subjects were divided into smoking group (n = 276), non-smoking group (n = 213). According to the condition of patients will quit smoking, smoking group was divided into two subgroups: quit-smoking group (n=81), not quit-smoking group (n=195). Results BMI, hypertension, hyperlipidemia, myocardial infarction, chronic obstructive pulmonary disease history were significantly higher than that of non-smoking group, the average age of left ventricular ejection fraction was significantly lower than that of the control group (P 0.05). If the COPD patients were excluded from the research, postoperative pulmonary complications, the time of mechanical ventilation of non-smoking groups was significantly lower than the smoking group; pulmon
