Findings from 2010 Global Adult Tobacco Survey: implementation of MPOWER policy in China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To assess the implementation of five key tobacco control policies in China: protection from second-hand smoke (SHS); offering help to quit; health warnings regarding tobacco use; the enforcement of bans on tobacco advertising, promotion, and sponsorship; and increasing tobacco taxes and prices.</p><p><b>METHODS</b>Using 2010 Global Adults Tobacco Survey in China (GATS-China), 10 indicators are used to assess the implementation of five key tobacco control policies of MPOWER in China.</p><p><b>RESULTS</b>Overall, 63.3% and 72.7% of adults noticed people smoking indoor workplaces and public places, respectively. Approximately 60% of smokers were not asked about their smoking habits and approximately 67% were not advised to quit on their visit to a health worker. Sixty percent of adults noticed health warning messages on cigarette packaging and in the media in the last 30 days, 63.6% stated that they would not consider quitting. Twenty percent of respondents noticed tobacco advertising, promotion, and/or sponsorship activities in the 30 days prior to the survey. Among them, 76.3% noticed the direct advertising and 50% noticed from TV programs. Although purchasing price of one pack of cigarettes ranged from 1 to 200 RMB, 50% of current smokers (about 150 million) spent 5 RMB or less on one pack of cigarette. The expenditure on 100 packets of cigarettes represents 2% of 2009 GDP per capita.</p><p><b>CONCLUSION</b>The average score for the implementation of the 5 policies of MPOWER in China is 37.3 points, indicating tobacco control policies in China is poor and there is a large gaps from the FCTC requirements.</p>

Studies on characteristic fingerprints of fat-soluble components of Marsdenia tenacissima by GC / 中国中药杂志

<p><b>OBJECTIVE</b>To study characteristic fingerprints of the fat-soluble components of different Marsdenia tenacissima samples by GC and GC-MS.</p><p><b>METHOD</b>The sample was split in the 280 degrees C injection port, with 10:1 split ratio, and separated on a fused silica capillary column (DB-5, 30 m x 0.25 mm I. D., 0.25 microm film). The temperature program was 70 degrees C for 5 min, 8 degrees C x min(-1) to 200 degrees C, then 5 degrees C x min-1 to 260 degrees C, 260 degrees C for 10 min. The high pure nitrogen was used as a carrier gas, The FID temperature was 300 degrees C.</p><p><b>RESULT</b>There are 15 common peaks in the GC fingerprints of M. tenacissima and they are identified by GC-MS. The analyses on cluster and similarity degree of the finger the crude drugs from various habitats have been performed.</p><p><b>CONCLUSION</b>The method has good repeatability. The GC fingerprint combined with the HPLC fingerprint of M. tenacissim can be used to evaluate its quality integrally.</p>
