Effects of strict control of tobacco advertisement after implementation of the Advertising Law WEI Xiao-xia, LI Ming, CHEN De, CAI Yu-yang, GAO Jing-rong 2017, 37 (02):  137.  doi: 10.3969/j.issn.1674-8115.2017.02.001 Abstract ( 882 )   PDF (5465KB) ( 1023 )   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.

Methods ·From July to October 2014, pregnant women and their spouses were recruited for a questionnaire investigation at the antenatal care clinics of 3 maternity hospitals and 3 community hospitals in Shanghai. The questionnaire included demographic information, family basic situation and cognitive status of passive smoking. Results · The passive smoking rate before pregnancy in the 2 831 pregnant women, who were involved in the investigation, was 17.1%. The passive rate during pregnancy was 7.8%. The difference between these two rates was statistically significant (P<0.05). 71.0% of the pregnant women have passive smoking for 15~59 min each day. Relative to home and work place, the passive smoking rate of pregnant women in public place was the highest (P<0.05). The passive smoking rate of pregnant women was significantly associated with the educational level of smoking spouses and the attitude of pregnant women when they faced the smokers. Conclusion · The passive smoking rate of pregnant women is influenced by the educational level of their spouses and the pregnant women’s feedback to the smokers face to face. Public places are the most important exposure places to secondhand smoke for pregnant women. In order to reduce the harm from passive smoking to pregnant women and their fetuses, the related measures of smoking control at home education and smoking ban in public place should be made.

Micro-structure changes in rat tooth movement process through micro-computed tomography dynamic observation CHEN Peng, YANG Feng-xue, ZHOU Jian-ping, DAI Hong-wei 2017, 37 (02):  193.  doi: 10.3969/j.issn.1674-8115.2017.02.012 Abstract ( 776 )   PDF (8478KB) ( 781 )   Objective · To observe the micro-structure changes in rat tooth movement process under different force values through Micro-CT dynamic observation. Methods · Fifteen SD adult male rats at the age of 8 weeks were divided into three groups randomly (n=5), with the left maxillary as the experimental side and the nickel titanium coil springs, fixed between the first molar and incisor where thrust augmentation was conducted respectively by 20, 50 and 100 gf (1gf=0.009 8 N) for continuous 14 d to it. Rat scanning in vivo through Micro-CT was carried out at day 0, 3, 7, 10 and 14 after force values were loaded on. The root resorption crater volumes and structure parameters for bone trabecula at different time points were measured. Results · Three days after thrust augmentation was conducted, root resorption crater volume for each group had a slight increase and an obvious increase occurred from the 3rd day to the 10th day, and then a slow increase happened 10 d later; from the 7th day to the 14th day, root resorption crater volume for 100 gf stress group was obviously greater than those of the other groups with statistical differences (P<0.05). With time for thrust augmentation passing by, bone volume fraction at the pressure side of alveolar bone decreased gradually and bone trabecula morphology became tiny and exiguous; besides, bone trabecula gap became narrow first and broad afterwards, and trabeculae trended to change from clintheriform to rhabditiform. Furthermore, alveolar bone resorption occurred in each stress group with consistent tendency. Conclusion · Different orthodontic force values all can cause root resorption, which experiences lag phase, rapid phase and stationary phase. Over-loaded orthodontic force induces more root resorption. During the process of the tooth movement, the pressure side of alveolar bones appears reconstruction and absorption, whose variation is not related with force degree. Related Articles | Metrics

Methods · The 8 vein samples were screened from 20 ESRD patients at their first time of the AVF construction (non-stenosis group), and the other 8 vein samples were screened from 15 ESRD patients at their at least second time of the AVF repair operation (stenosis group). Sections were prepared and stained with hematoxylin & eosin (H-E) or Masson’s trichrome for observation. The intimal thickness was measured by the cellSens software, and its correlation with patients’ renal function, calcium-phosphorus metabolism, iron metabolism and inflammatory reaction in the non-stenosis group were analyzed. Results · In the non-stenosis group, there were varying degrees of intimal hyperplasia in 5 (62.5%) cases, loss of endothelial cell layer in 3 (37.5%) cases, and vascular wall replacement by collagenous with atrophy or loss of muscle layer in 5 (62.5%) cases. In the stenosis group, almost all vein samples showed general thickening of the wall and 2 (25.0%) totally lost the muscle layer. Avg It of those two groups were statistically significant (P<0.01). In the non-stenosis group, both of average I/M thickness and average I/M area were negatively related to glomerular filtration rate (GFR) (P<0.05) and positively related to serum phosphorus and calcium-phosphorus product (P<0.05). Conclusion · Some apparently normal vein of ESRD patients showed varying degrees of intimal hyperplasia before AVF construction. The intimal hyperplasia had a remarkable correlation with GFR or calcium-phosphorus metabolism. Early intervention of the intimal hyperplasia prior to AVF construction may be a new prevention and control means. Related Articles | Metrics

In recent years, many researches have showed that colonized intestinal microbiota plays an important role in the communication between gut and brain. On one hand, microbiota can influence the development and function of brain via GBA. On the other hand, brain can also change the composition of gut microbiota. These findings gradually become a novel medical research highlight, i.e. the microbiota-gut-brain axis. This paper reviews the interaction between gut microbiota and brain via GBA in order to provide supports for studying functions of gastrointestinal tract and brain, as well as the treatment of related diseases.
