Abstract
CONTEXT: In recent decades, there has been a rapid and substantial increase in tobacco consumption in China, particularly by men, but little is known from local epidemiologic studies about the pattern of smoking-related deaths. OBJECTIVE: To assess the current health effects of cigarette smoking in Shanghai, China. DESIGN: Prospective observational study of mortality in relation to cigarette smoking. SETTING: Eleven factories in urban Shanghai. SUBJECTS: A total of 9351 adults (6494 men and 2857 women) aged 35 to 64 years at baseline survey during the 1970s. OUTCOME MEASURES: All-cause and cause-specific mortality. RESULTS: During an average follow-up of 16 years, 881 men and 207 women died. Among men, 61% had described themselves as current cigarette smokers at baseline, and their overall mortality was significantly greater than that of nonsmokers (relative risk [RR], 1.4; 95% confidence interval [CI], 1.2-1.7; P<.001). The excess was almost twice as great (RR, 1.8; 95% CI, 1.5-2.2 [corrected]; P<.001) among the men who had begun smoking before the age of 25 years and was significantly associated with the number of cigarettes smoked (P<.001 for trend) after adjustment for other major risk factors. The chief sources of the excess were lung cancer (RR, 3.8; 95% CI, 2.1-6.8; P<.001), esophageal cancer (RR, 3.6; 95% CI, 1.2-10.5; P=.02), liver cancer (RR, 2.0; 95% CI, 1.1-3.7; P=.03), coronary heart disease (RR, 1.8; 95% CI, 1.0-3.2; P=.04), and chronic obstructive pulmonary disease (RR, 2.5; 95% CI, 1.4-4.4; P<.01). Among the men in this Chinese population, about 20% (95% CI, 12%-29%) of all deaths during the study period could be attributed to cigarette smoking. Of these deaths, one third involved lung cancer, one third involved other cancers, and one third involved other diseases. Only 7% of women described themselves as current cigarette smokers at baseline, but among them there was also a statistically significant excess of overall mortality (RR, 1.7; 95% CI, 1.2-2.5; P<.01). CONCLUSIONS: Cigarette smoking is already a major cause of death in China, and among middle-aged Shanghai men, about 20% of all deaths during the 1980s were due to smoking. The excess was greatest among men who began smoking before the age of 25 years, about 47% of whom would, at 1987 mortality rates, die between the ages of 35 and 69 years (compared with only 29% of nonsmokers). These estimates reflect the consequences of past smoking patterns. The future health effects of current smoking patterns are likely to be greater because of the recent large increase in cigarette consumption, particularly at younger ages, in China.

Abstract
AIM: To determine the combined effect of very low nicotine content (VLNC) cigarettes and usual Quitline care [nicotine replacement therapy (NRT) and behavioural support] on smoking abstinence, in smokers motivated to quit. DESIGN: Single-blind, parallel randomized trial. SETTING: New Zealand. PARTICIPANTS Smokers who called the Quitline for quitting support were randomized to either VLNC cigarettes to use whenever they had an urge to smoke for up to 6 weeks after their quit date, in combination with usual Quitline care (8 weeks of NRT patches and/or gum or lozenges, plus behavioural support) or to usual Quitline care alone. MEASUREMENTS: The primary outcome was 7-day point-prevalence smoking abstinence 6 months after quit day. Secondary outcomes included continuous abstinence, cigarette consumption, withdrawal, self-efficacy, alcohol use, serious adverse events and views on the use of the VLNC cigarettes at 3 and 6 weeks and 3 and 6 months. FINDINGS: A total of 1410 participants were randomized (705 in each arm), with a 24% loss to follow-up at 6 months. Participants in the intervention group were more likely to have quit smoking at 6 months compared to the usual care group [7-day point-prevalence abstinence 33 versus 28%, relative risk (RR) = 1.18, 95% confidence interval (CI): 1.01, 1.39, P = 0.037; continuous abstinence 23 versus 15%, RR = 1.50, 95% CI: 1.20, 1.87, P = 0.0003]. The median time to relapse in the intervention group was 2 months compared to 2 weeks in the usual care group (P

Abstract
BACKGROUND: Advances in technology allowed the development of a novel smoking cessation program delivered by video messages sent to mobile phones. This social cognitive theory-based intervention (called "STUB IT") used observational learning via short video diary messages from role models going through the quitting process to teach behavioral change techniques. OBJECTIVE: The objective of our study was to assess the effectiveness of a multimedia mobile phone intervention for smoking cessation. METHODS: A randomized controlled trial was conducted with 6-month follow-up. Participants had to be 16 years of age or over, be current daily smokers, be ready to quit, and have a video message-capable phone. Recruitment targeted younger adults predominantly through radio and online advertising. Registration and data collection were completed online, prompted by text messages. The intervention group received an automated package of video and text messages over 6 months that was tailored to self-selected quit date, role model, and timing of messages. Extra messages were available on demand to beat cravings and address lapses. The control group also set a quit date and received a general health video message sent to their phone every 2 weeks. RESULTS: The target sample size was not achieved due to difficulty recruiting young adult quitters. Of the 226 randomized participants, 47% (107/226) were female and 24% (54/226) were Maori (indigenous population of New Zealand). Their mean age was 27 years (SD 8.7), and there was a high level of nicotine addiction. Continuous abstinence at 6 months was 26.4% (29/110) in the intervention group and 27.6% (32/116) in the control group (P = .8). Feedback from participants indicated that the support provided by the video role models was important and appreciated. CONCLUSIONS: This study was not able to demonstrate a statistically significant effect of the complex video messaging mobile phone intervention compared with simple general health video messages via mobile phone. However, there was sufficient positive feedback about the ease of use of this novel intervention, and the support obtained by observing the role model video messages, to warrant further investigation.

Abstract
BACKGROUND: Innovative effective smoking cessation interventions are required to appeal to those who are not accessing traditional cessation services. Mobile phones are widely used and are now well integrated into the daily lives of many, particularly young adults. Mobile phones are a potential medium for the delivery of health programmes such as smoking cessation. OBJECTIVES: To determine whether mobile phone-based interventions are effective at helping people who smoke, to quit. SEARCH STRATEGY: We searched MEDLINE, EMBASE, Cinahl, PsycINFO, The Cochrane Library, the National Research Register and the ClinicalTrials register, with no restrictions placed on language or publication date. SELECTION CRITERIA: We included randomized or quasi-randomized trials. Participants were smokers of any age who wanted to quit. Studies were those examining any type of mobile phone-based intervention. This included any intervention aimed at mobile phone users, based around delivery via mobile phone, and using any functions or applications that can be used or sent via a mobile phone. DATA COLLECTION AND ANALYSIS: Information on the specified quality criteria and methodological details was extracted using a standardised form. Participants who dropped out of the trials or were lost to follow up were considered to be smoking. Meta-analysis of the included studies was undertaken using the Mantel-Haenszel Risk Ratio fixed-effect method provided that there was no evidence of substantial statistical heterogeneity as assessed by the I(2) statistic. Where meta-analysis was not possible, summary and descriptive statistics are presented. MAIN RESULTS: Four studies were excluded as they were small non-randomized feasibility studies, and two studies were excluded because follow up was less than six months. Four trials (reported in five papers) are included: a text message programme in New Zealand; a text message programme in the UK; and an Internet and mobile phone programme involving two different groups in Norway. The different types of interventions are analysed separately. When combined by meta-analysis the text message programme trials showed a significant increase in short-term self-reported quitting (RR 2.18, 95% CI 1.80 to 2.65). However, there was considerable heterogeneity in long-term outcomes, with the much larger trial having problems with misclassification of outcomes; therefore these data were not combined. When the data from the Internet and mobile phone programmes were pooled we found statistically significant increases in both short and long-term self-reported quitting (RR 2.03, 95% CI 1.40 to 2.94). AUTHORS' CONCLUSIONS: The current evidence shows no effect of mobile phone-based smoking cessation interventions on long-term outcome. While short-term results are positive, more rigorous studies of the long-term effects of mobile phone-based smoking cessation interventions are needed.

Abstract
Anaplastic lymphoma kinase, an insulin receptor protein-tyrosine kinase, is a very attractive receptor protein target for anticancer therapy. Pharmacophore hypotheses modeling, virtual screening and molecular docking were used to detect potential inhibitors of anaplastic lymphoma kinase in this paper. After the generation of ten pharmacophore hypotheses, Hypo1 with the highest correlation value (0.981), lowest RMS (0.565), highest cost difference (83.850) along with four typical chemical features was regarded as the best hypothesis. Hypo1 contains a hydrogen bond acceptor, a hydrogen bong donor, a hydrophobic and a ring aromatic feature. And then, hypo1 was validated and used to screen three databases after screened by Lipinski's rule of five. 3015 hits screened by Hypo1 were submitted to molecular docking based on the crystal structure of anaplastic lymphoma kinase. Ultimately, 7 molecules with four different scaffolds were selected as potential leads for designing the anaplastic lymphoma kinase inhibitors.

Abstract
A simple and environmentally friendly method for determination of seven phenols using solid-phase microextraction (SPME) coupled to high-performance liquid chromatography (HPLC) has been developed. Several materials were used as stationary phase of SPME fibers and an oxidized multiwalled carbon nanotubes material was found to be effective in carrying out simultaneous extraction of phenols in aqueous samples. Compared with the widely used commercially available SPME fibers, this proposed fiber had much lower cost, longer lifetime (over 150 times), shorter analysis time (30 min of extraction and 3 min of desorption time) and comparable or superior extraction efficiency for the investigated analytes. The extraction and desorption conditions were evaluated and the calibration curves of seven phenols were linear (R(2)> or =0.9908) in the range from 10.2 to 1585 ng mL(-1). The limits of detection at a signal-to-noise (S/N) ratio of 3 were 0.25-3.67 ng mL(-1), and the limits of quantification calculated at S/N=10 were 0.83-12.25 ng mL(-1) for these compounds. The possibility of applying the proposed method to environmental water samples analysis was validated.

Abstract
A novel mesoporous-coated stainless steel wire microextraction coupled with the HPLC procedure for quantification of four polycyclic aromatic hydrocarbons in water has been developed, based on the sorption of target analytes on a selectively adsorptive fiber and subsequent desorption of analytes directly into HPLC. Phenyl-functionalized mesoporous materials (Ph-SBA-15) were synthesized and coated on the surfaces of a stainless steel wire. Due to the high porosity and large surface area of the Ph-SBA-15, high extraction efficiency is expected. The influence of various parameters on polycyclic aromatic hydrocarbons extraction efficiency were thoroughly studied and optimized (such as the extraction temperature, the extraction time, the desorption time, the stirring rate and the ionic strength of samples). The results showed that each compound for the analysis of real water samples was tested under optimal conditions with the linearity ranging from 1.02x10(-3) to 200 mug/ L and the detection limits were found from 0.32 to 2.44 ng/ L, respectively. The RSD of the new method was smaller than 4.10%.

Abstract
A novel titanium dioxide-nanosheets coating on a titanium wire (TiO2NS-Ti) was in situ fabricated by one-step electrochemical anodization in ethylene glycol with ammonium fluoride and followed by phenyl-functionalization for selective solid-phase microextraction (SPME). The fabricated TiO2NS coating exhibits higher specific surface area and more active sites, it also provides an ideal nanostructure and a robust substrate for subsequent surface modification. These characteristics were useful for efficient extraction. The SPME performance of phenyl-functionalized TiO2NS-Ti (ph-TiO2NS-Ti) fiber was evaluated by using ultraviolet filters, polychlorinated biphenyls and polycyclic aromatic hydrocarbons (PAHs) as model compounds coupled to high performance liquid chromatography with UV detection (HPLC-UV). It was found that the ph-TiO2NS-Ti fiber exhibited high extraction capability, good selectivity and rapid mass transfer for PAHs. The main parameters affecting extraction performance were investigated and optimized. Under optimized conditions, the proposed fiber showed good extraction efficiency comparable to those of commercial polydimethylsiloxane and polyacrylate fibers toward PAHs. The calibration graphs were linear over the range of 0.05-300 microg L(-1). The limits of detection of the proposed method were 0.008-0.043 microg L(-1) (S/N=3). Single fiber repeatability varied from 3.51% to 5.23% and fiber-to-fiber reproducibility ranged from 4.43% to 7.65% for the extraction of water spiked with 25 microg L(-1) each analyte (n=5). The established SPME-HPLC-UV method was successfully applied to selective concentration and sensitive determination of target PAHs from real environmental water samples with recoveries from 86.2% to 112% at the spiking level of 10 microg L(-1) and 50 microg L(-1). The relative standard deviations were below 9.45%. Furthermore, the ph-TiO2NS-Ti fiber can be fabricated in a reproducible manner, and has high stability and long service lifetime.

Abstract
A novel zinc-zinc oxide (Zn-ZnO) nanosheets coating was directly fabricated on an etched stainless steel wire substrate as solid-phase microextraction (SPME) fiber via previous electrodeposition of robust Zn coating. The scanning electron micrograph of the Zn-ZnO nanosheets coated fiber exhibits a flower-like nanostructure with high surface area. The SPME performance of as-fabricated fiber was investigated for the concentration and determination of polycyclic aromatic hydrocarbons, phthalates and ultraviolet (UV) filters coupled to high performance liquid chromatography with UV detection (HPLC-UV). It was found that the Zn-ZnO nanosheets coating exhibited high extraction capability, good selectivity and rapid mass transfer for some UV filters. The main parameters affecting extraction performance were investigated and optimized. Under the optimized conditions, the calibration graphs were linear over the range of 0.1-200mugL(-1). The limits of detection of the proposed method were 0.052-0.084mugL(-1) (S/N=3). The single fiber repeatability varied from 5.18% to 7.56% and the fiber-to-fiber reproducibility ranged from 6.74% to 8.83% for the extraction of spiked water with 50mugL(-1) UV filters (n=5). The established SPME-HPLC-UV method was successfully applied to the selective concentration and sensitive determination of target UV filters from real environmental water samples with recoveries from 85.8% to 105% at the spiking level of 10mugL(-1) and 30mugL(-1). The relative standard deviations were below 9.7%.

Abstract
Multiwalled carbon nanotubes (MWCNTs) were used as a novel kind of solid-phase extraction adsorbents in this work as well as an analytical method based on MWCNTs solid-phase extraction (SPE) combined with high-performance liquid chromatography (HPLC) was established for the determination of polycyclic aromatic hydrocarbons (PAHs), some of which belong to typical persistent organic pollutants (POPs) owing to their carcinogenicity and endocrine disrupting activity. Several conditions that probably affected the extraction efficiency including the eluent volume, sample flow rate, sample pH and the sample volume were optimized in detail. The characteristic data of analytical performance were determined to investigate the sensitivity and precision of the method, and the method was applied to the determination of PAHs in environmental water samples such as river water sample, tap water sample and wastewater sample from the constructed wetland effluent. The experimental results indicated that there were excellent linear relationship between peak area and the concentration of PAHs over the range of 0.04-100 microg L(-1), and the precisions (RSD) were 1.7-4.8% under the optimal conditions. The detection limits of proposed method for the studied PAHs were 0.005-0.058 microg L(-1) (S/N=3). The recoveries of PAHs spiked in environmental water samples ranged from 78.7 to 118.1%. It was concluded that MWCNTs packed cartridge coupled with HPLC was an excellent alternative for the routine analysis of PAHs at trace level.
