Introduction: China is the biggest tobacco producer and consumer in the world. Raising cigarette taxes and increasing tobacco retail prices have been prove as effective strategies to reduce tobacco consumption and the prevalence of smoking in western countries. But in China, it is uncertain how an increase of cigarette retail price will influence the tobacco consumption. Methods: From April to July, 2012, we selected 4025 residents over 15 years by a three stage random sampling in four cities, Jiangxi Province, China. We conducted interviews of their current smoking habits and how they would change their smoking behavior if tobacco retail prices increase. Results: Overall, the prevalence of smoking is 27 % (47 % for male, 3.1 % for female). 15 % of smokers have tried to quit smoking in the past but all relapsed (168/1088), and over 50 % of current smokers do not want to quit, The average cigarette price per pack is 1.1 USD (range = 0.25-5.0). If retail cigarette prices increases by 50 %, 45 % of smokers say they will smoke fewer cigarettes, 20 % will change to cheaper brands and 5 % will attempt to quit smoking. Smokers who have intention to quit smoking are more sensitive to retail cigarette price increase. With retail cigarette price increases, more smokers will attempt to quit smoking. Conclusion: Chinese smokers will change their smoking habits if tobacco retail prices increase. Consequently the Chinese government should enact tobacco laws which increase the retail cigarette price. The implementation of new tobacco laws could result in lowering the prevalence of smoking. Meanwhile, price increase measures need to apply to all cigarette brands to avoid smokers switching cigarettes to cheaper brands. © 2015 wang et al. Source

BACKGROUND: In April 2013, a hospital in Suzhou City notified authorities of a patient with nitrite poisoning with two other family members who had similar toxic symptoms five days prior. We investigated the event to identify the cause, source and possible route of contamination.METHODS: A case was defined as any person living in the Yang Shan Hua Yuan community who had been diagnosed with cyanoderma and food poisoning symptoms from 15 to 25 April 2013. Active case finding was conducted by interviewing community residents and reviewing medical records from local clinics; information was then retrospectively collected on the patient's food history, cooking procedures and food sources.RESULTS: We identified three nitrite poisoning cases, one male and two females, from the same family. The time between dinner and onset of illness was less than an a hour. A retrospective survey showed that a substance presumed to be sugar mixed with asparagus on 17 April and with stir-fried asparagus on 21 April was the suspected contaminant. The presumed sugar came from a clean-up of a neighbouring rental house. Nitrite was detected in a vomitus sample, the sugar substance and two leftover food samples.CONCLUSION: This family cluster of nitrite poisoning resulted from the mistaken use of nitrite as sugar to cook dishes. We recommend that sodium nitrite be dyed a bright colour to prevent such a mistake and that health departments strengthen food hygiene education to alert people about the danger of eating unidentified food from an unknown source.
