Objective · To compare the prevalence of tobacco advertisement before and after implementation of the new edition of Advertising Law of the People's Republic of China and evaluate the effects of implementation of the new Advertising Law. Methods · Tobacco sales places, public places, and streets in Shanghai were randomly selected to observe tobacco advertisement and complete the survey. The survey was carried out in 10 districts of Shanghai in June 2015 with 10 tobacco sales places selected in each district, and in 4 districts of Shanghai in June 2016 with 25 tobacco sales places selected in each district. Sales places included convenient stores, tobacco stores, supermarkets, and kiosks. In addition, public transport waiting points, public transport vehicles, hospitals, shopping centers, restaurants, bars, and Internet cafes were selected into survey in 2016. Results · In 2016, the proportion of tobacco sales places having tobacco advertisement was lower than that in 2015, but the proportion of tobacco promotion behaviors was higher. In 2016, 128 public places and streets were investigated and only 1 had outdoor tobacco advertisement. Conclusion · The new edition of Advertising Law has significant effect on controlling tobacco advertisement, but tobacco sales places still have tobacco advertisement with various disguised promotion forms. Tobacco sales places have diversified business styles and minors often enter these places. It is recommended that a clear definition of disguised forms of tobacco advertisement should be made, tobacco advertisement at tobacco sales places needs to be supervised, the release of tobacco advertisement should be strictly reviewed, and existing tobacco advertisement should be severely punished, so as to prevent minors from exposing to tobacco advertisement and information luring smoking.

Objective To investigate the influence of primary cultured neonatal rat hippocampal neurons caused by human cytomegalovirus (HCMV AD169) infection on intracellular calcium and its mechanism.Methods Twenty SPF SD rats born within 24 hours(10 cases of male and 10 cases of female) were assigned to establish the primary rat hippocampal neuronal monolayer cells; After cultured 8 days in vitro,the eligible cells were randomly divided into HCMV infection group,HCMV + MK-801 group,MK-801 group and control group,with 10 wells in each group.The fluorescence intensity values of the intracellular free calcium were detected after 24 hours of treatment with Fluo-3AM fluorescence staining.Results Inoculation of HCMV neurons after 24 h turned to round and swollen gradually,and 4days later,most of the cells disappeared; by immunohistochemistry in cultures of hippocampal neurons in HCMV,visible early proteins,brownish yellow granules,hematoxylin were found after being stained with brown pigment.The fluorescence intensity values of neuronal intracellular calcium (215.5 ± 14.9) in HCMV group was higher than that of control group (116.4 ± 5.9) (t =15.2,P < 0.01),whilerise,that in MK-801 group (88.1 ± 4.5) was significantly lower than that of control group,with decreased rate of (24.0 ± 6.7) % (t =-9.3,P < 0.01).The fluorescence intensity values of neuronal intracellular calcium in HCMV + MK-801 group (135.5 ± 8.6) was significantly decreased compared with that of HCMV group (215.5 ± 14.9),with decreased rate of (37.0 ± 3.4) % (t =11.3,P < 0.01).Conclusions Intracellular calcium overload of cultured rat hippocampal neurons in vitro with HCMV AD16 strains infection can be detected.One of its main mechanisms is the N-methyl-D-aspartic acid receptor channel-mediated calcium influx.
