ABSTRACT
Objective To explore the behaviors of smokers as well as the tobacco consumption in Jiangxi province.Impact regarding the increases of tobacco retail price on the smoking behaviors among cigarette consumers was also studied.Data was provided for further development on measurements including legislation,taxing and increasing the retail price on tobacco.Methods 805 residents above 15 year-olds were chosen through random clustered sampling,and face to face interviewed,in Shangrao and Yichun of Jiangxi province.A chart was drawn to show the relationship between the change of smoking behavior and the increase of sales price of tobacco.Results The average rate of smoking was 27.08％ (46.62％ for males and 3.05％ for females).16.06％ (35/218) of the smokers had ever tried to quit smoking but failed.The years of smoking ranged from 1 year to 50 years,with 96.33％ of the smokers purchased cigarettes on their own.Price of the cigarette ranged from 15 to 30 RMB per package,and smokers usually spent on average 192 RMB which accounted 13％ of their monthly income,per month.According to the chart,if the cigarette price had a 50％ increase,it would lead to 45％ of the smokers reduce the number of cigarette consumption with another 5％ of the smokers attempt to quit smoking.If cigarette price had an increase by 2 times,50％ of the smokers would attempt to quit smoking.So the chart could be used to estimate the percentage of smokers' behavior change according to the increase of tobacco's sales price.Conclusion The cconomy burden of tobacco consumption among cigarette smokers was huge,suggesting that the Chinese smokers did need to change their smoking behavior.Chinese government should develop tobacco-related legislations and laws and set proper cigarette tax,hopefully this could reduce the number of smokers in a long run.
ABSTRACT
<p><b>OBJECTIVE</b>To study the relation between the nitric-oxide synthase (NOS) expression and nitric oxide (NO) content in the skeletal muscles and the injury condition of soft tissue in the 3rd lumbar vertebrae syndrome model rats, and to observe the effect of acupotomology therapy.</p><p><b>METHODS</b>One hundred and twenty-eight adult SD rats were allocated to 4 groups randomly: normal group, model group, aminoguanidin group and acupotomology treatment group, 32 rats in each group. NOS expression, NO content and injury of the soft tissue in the 3rd lumbar vertebra were observed on the 1st, 3rd, 7th and 14th day after the acupotomology treatment and aminoguanidine intervention.</p><p><b>RESULTS</b>1) Inducible NOS (iNos) activity and NO content in model group was significantly higher (F = 522.860, P < 0.01), in acupotomology group and aminoguanidine group was significantly lower than the model group (FiNOS = 28.894, P < 0.01), and iNOS activity and NO content in all groups was in competence with the condition of soft tissue injuries. 2) Endothelium NOS (eNOS) expression raised in model group and acupotomology group, and achieve peak on the 7th day. There was significant difference between the eNOS expression in acupotomology group and the model group (FeNOS = 3.454, P < 0.05). 3) The expression of neuron NOS (nNOS) in the model group, aminoguanidine group and acupotomology group had no significant (FnNOS = 0.962, P > 0.05).</p><p><b>CONCLUSION</b>Acupotomology treatment can restrain the development of high content NO, release the inflammatory reaction and injury condition, improve microcirculation, prevent the development of scar tissue of the injured soft tissue, and has significant recovering effectiveness in the soft tissue injured model rats.</p>
